If the construction of the house is carried out from aerated concrete, the best overlap for it is wooden. This is the most economical option that can be made by hand.
Only two people are required to install it. Another advantage of wood is its low weight, which is very important for aerated concrete.
Wooden floors in a house made of aerated concrete are interfloor, basement and attic. The fundamental difference between them is small, but there are some features of their arrangement.
Since gas blocks have a relatively fragile structure, it is necessary to form a reinforcing belt of reinforced concrete before arranging the ceiling on the walls. It will evenly distribute pressure loads over the entire area of the walls, and also additionally strengthen the walls of the house.
To create an armored belt, U-shaped gas blocks are used, which are stacked as the top row. In the absence of such blocks, they can be made independently by cutting out recesses in ordinary aerated concrete. After laying the U-shaped blocks, a power frame of reinforcement is formed in the recesses. It consists of four longitudinal rods interconnected in single structure. Pieces of wood are placed under the bottom reinforcement to create a monolithic layer of concrete under the metal.
After that, concrete is poured into blocks. The surface for laying the floor is ready. The armored belt can also be made without U-shaped blocks, simply by pouring concrete into the formwork fixed over the walls, but this method is too time-consuming.
We list the procedure for performing work on the creation of an interfloor ceiling made of wood.
Approximate scheme of a wooden floor. Designations: 1 - floor; 2 - waterproofing; 3 - insulation; 4 - counter rail; 5 - beam; 6 - draft ceiling; 7 - vapor barrier; 8 - interior finishing.
The formation of the overlap begins with the laying of power beams on the walls. They are placed perpendicular to long walls Houses. The laying step usually does not exceed 1 m. B Alkas should go on the walls at least 15 cm. First, the extreme beams are installed, which are displayed in level, by means of a long and even board, placed on the end. There should not be a tight abutment of the extreme beams to the walls. A gap of about 3–4 cm should be left between them. Subsequently, this gap will be filled with insulation.
Installed wooden beams
The outer beams are mounted on the wall, after which the remaining beams are installed. Not only their level is controlled, but also the horizontal position. If the length of the support beams turned out to be insufficient, they can be built up with the same material. To do this, two beams are overlapped from 0.5 m to 1 m, after which they are bolted. Such a connection is considered quite reliable.
The beam is fastened to the armored belt by means of anchor plates in the following order:
Tip: the ends of the beams must not be coated with oily impregnations or paint. In this case, the evaporation of moisture from the wood will be disturbed.
The voids between the laid beams are filled. This can be done with bricks, but preferably with gas blocks. Between the blocks and the tree, it is necessary to leave gaps of 2-3 cm. These voids are tightly clogged mineral wool. This prevents the formation of condensate and dampness of the wood from contact with the walls.
To insulate the ceiling, it is necessary to make a roll. Along the bottom of the laid beams, 5x5 cm bars are attached. They can be fixed with long self-tapping screws. Boards of boards are laid on them, but separate cut-out pieces of boards can also be used. Insulation (mineral wool or expanded polystyrene) is tightly laid on the boards. The recommended thickness of the insulation is from 10 cm.
On top of the created structure, perpendicular to the beams, logs are laid, which are also pre-treated with special impregnations. Logs usually have a smaller section than beams. The step of laying the log is 50–70 cm. The logs are attached to the beams. Floor boards are laid over the fixed logs. The bottom cover is sheathed OSB boards, chipboard, drywall or plywood.
If the ceiling is made over a heated basement, its design is no different from the interfloor ceiling device. If the basement is cold, like basement, there are some features of its arrangement.
Since water vapor tends to circulate from warm room in a cold basement, the heat insulator will absorb a lot of moisture. To prevent this, a layer of vapor barrier is laid on top of it. It is also recommended to increase the thickness of the insulation layer to 20 cm. All beams, as well as others wooden elements floors must be protected from decay with special compounds.
difference attic floor from the interfloor consists in the absence of a floor, as well as in the use of a thicker layer of thermal insulation. If an attic is arranged on top, then the floor is also made. A wooden floor for walls made of aerated concrete blocks, with correct installation, will ensure the reliability and durability of the built house. At the same time, the cost of work and materials will be much lower than when using reinforced concrete floors.
Aerated concrete is a material with which you can quickly build a house. It holds heat well and is easy to install. Aerated concrete buildings build a maximum of up to 3 floors. This is due to the calculation of the ultimate load. Overlapping in such houses are different types, depending on the wishes of the customer. Let's try to understand most of them.
The floors of the first floor are a structurally important part of the building. It is on them that the entire vertical load of the walls of the house made of aerated concrete falls. Also, the ceilings have to withstand the weight of the installed furniture, flooring and people living in the building. In addition, they provide the necessary rigidity to the structure. Photo of wooden beams different section at the bottom.
It is especially important to correctly calculate and select floors for houses made of aerated concrete. This material, due to its porosity, has a lower compressive strength, which must be taken into account when choosing beams of different sections or other structures for a building made of gas silicate blocks.
There are several floor options for aerated concrete houses. Each of them has its pros and cons and is suitable in a particular case. Types best designs overlays can be divided into the following types depending on the materials used and installation technologies.
Below you can see a photo of the installation of structures with beams of different sections and others.
Installation wooden floors V aerated concrete house on the beams is one of the best options. A feature of this design is the obligatory armored belt on aerated concrete, on which it will be installed. Wooden beams of different sections are fixed with studs, as well as metal corners and plates. This method is quite reliable for structures made of gas silicate blocks.
The device of wooden floors in a house made of aerated concrete on large-section beams differ from each other according to several criteria. First of all, this concerns the material from which the beams are made. The best forms are edged board or timber, in some cases a log. Increasingly in Lately I-beams are widely used for installation, a little less often glued laminated timber in a private house made of aerated concrete.
The arrangement of ceilings from wooden beams of large cross-section on an armored belt on aerated concrete may also differ in the way the voids are filled. For this, the roll of their shields on top of the cranial bars, as well as insulation, vapor and waterproofing materials can be used.
The arrangement and installation of wooden floors in a house made of aerated concrete along the beams on the armored belt may also differ according to the material used for filing the beams. It can be drywall sheets, plywood, chipboard, plastic lining, Often the bottom of a wooden floor in a house made of aerated concrete along the beams is left without filing, creating the effect of antiquity or embodying others design solutions. Photo and video solutions with beams and their The best way installation is below.
Monolithic overlap in a house made of aerated concrete, along beams of different sections, it is done independently at the construction site. The exception is the concrete itself, which is needed for installation. It is not recommended to do it in small-sized mixers, but it is better to order it ready-made directly from specialized companies. This is due to the fact that monolithic floors are a structure that is responsible for the safety of people living in aerated concrete houses. Manually preparing reliable concrete is quite difficult.
The most important part of a monolithic floor is the frame. It is made from small section reinforcement and required thickness, tying with wire. The metal frame will take all the load from the concrete. It is mounted in a pre-prepared wooden formwork. Usually the thickness of a monolithic floor in gas silicate houses is made with a thickness of 150-300 mm. heavy load gas silicate blocks may not endure.
The advantages of a monolithic design include:
Monolithic structures in a house made of gas silicate blocks, in addition to the advantages, have a number of disadvantages. These include:
The device of the best interfloor floors in a house made of aerated concrete on wooden beams of different sections or on a monolithic basis is one of the most important. Its feature is the need to install a floor on which people will walk and household items and furniture will be installed. As a result, the load on the best interfloor ceilings will increase significantly in the aerated concrete house on the installed beams.
One of the best solutions is the installation of a wooden floor, namely natural or glued beams, as well as modern I-beams. The step of their installation in the best interfloor ceiling in an aerated concrete house depends on the section, but usually it is 0.6 - 1.2 meters. The best length of large beams in the house is 6 meters. In the photo you can see the correct calculation and installation of the best wooden floor and the number of beams on the first and second floor.
In the wooden floor of an aerated concrete house, excellent beams are mounted at right angles to the load-bearing walls. They will be installed on a reinforced concrete reinforcing belt prepared in advance. Previously, under the wooden beams installed on the walls, in the planned arrangement of floors in the house of aerated concrete, a layer of waterproofing is laid.
The size of the niche should be 2-3 cm. The beam in the aerated concrete house should lie on the reinforcing belt for a length of 15 cm. The supporting part should be wrapped in a layer of roofing material over bitumen or with a self-adhesive membrane. In places where wooden beams are installed on a monolithic reinforcing belt of aerated concrete house, anchors or plates are installed. Look at the photo best solutions installations on gas silicate blocks.
According to the principle of the device basement on wooden beams aerated concrete house almost does not differ from the interfloor. Although there are some features.
A feature of the device of the attic wooden floor in aerated concrete houses, in contrast to the interfloor, is the absence of laying the floor along the beams in most cases. Except for the moments when the attic will be used as living rooms.
If the premises will be used as a pantry, for example, then only the subfloor along the beams will be enough. Most often on the attic wooden floor in elite house from aerated concrete, instead of the floor, unlike the interfloor, they will simply lay bridges, along which you can exercise control over the state truss system or roofs.
To prevent cold from penetrating from an unheated attic into the interblock space, insulation should be laid along the beams. His optimum thickness should be 15-20 cm. Due to the lower load on the wooden floor in the house of aerated concrete, in contrast to the interfloor, it can be made from beams of smaller diameter, as seen in the photo.
Regardless of which material is chosen for the installation of floors in an aerated concrete house, the work requires special knowledge and skills. The video below shows step by step the process of installing wooden beams on gas silicate blocks.
For the installation of metal and wooden interfloor floors of a house from gas silicate blocks, the main stages are the manufacture of beams, their installation on special gaps in the reinforcing belt, the installation of flooring from boards or profiles, all necessary insulation and waterproofing layers, gender.
The monolithic works of the first floor consist of the preparation of the formwork, the manufacture of the frame and the pouring of concrete. Tiled interfloor are considered the simplest, you just need to correctly place the workpieces on the bearing walls of gas silicate blocks, as in the photo.
For the device of overlapping the first floor in a house made of aerated concrete, any possible types of structures can be suitable. It can be tiled, monolithic, wooden or metal beams along a reinforced belt. The ceilings of the first floor in the house do not receive negative effects from either cold or damp basement, nor from the attic. Although often they account for the main load on the beams.
Usually heavy furniture, bedrooms are placed on the second floor, people often move. Therefore, you need to carefully calculate the load on interfloor monolithic wooden floors and beams in a house made of gas silicate blocks, see the photo.
After overlapping the second floor, there is usually an attic. If it is made in the form of an attic, where it is supposed to be placed living rooms, then the requirements for the interfloor wooden floor made of beams in a house made of gas silicate blocks will be the same as after the first floor. If the attic is non-residential or not equipped at all due to its low height, then you can make a lightweight structure without flooring or limit yourself to installing a rough one. A photo of the beams is just below.
The device of a reinforced belt on an aerated concrete house is a fundamental thing for floors of the first floor along wooden beams. It has several meanings. First, thanks to the interfloor monolithic armored belt the entire aerated concrete house is strengthened on the aerated concrete, reliably tightening the aerated concrete.
The room becomes more protected from sediment and deformation. Secondly, wooden or metal floor beams in an aerated concrete house are laid on the reinforcing belt. Photos and videos of the reinforced belt are just below.
In order to install a monolithic armored belt on aerated concrete under wooden floors, special material with a gutter is used. They set metal carcass from fittings. Then concrete is poured for the reinforced belt. To preserve heat outside the wall, polystyrene insulation is added for floors on wooden beams in an aerated concrete house.
If it is impossible to purchase special aerated concrete, then you can make a regular monolithic reinforced belt or make the necessary holes yourself. Photos and videos of the structure below, as well as the wooden beams located on them.
What is the best floor for an aerated concrete house? Or which one is more reliable? Such questions are often asked by people planning to build a house from aerated concrete. There is no single answer to them. But it is possible to highlight the fundamental points.
But aerated concrete also has a minus - due to its low strength, when pressure is applied to it from ceilings, the walls can crack. For this reason, when building floors in such houses, it is necessary. Next, we will talk about wooden floors in a house made of aerated concrete.
Wooden beams boast their lightness and ease of installation. There is an erroneous opinion that a reinforcing layer is not needed for light wooden floors. This is fundamentally not true.
For aerated concrete walls, regardless of the type of overlap, an armored belt is always needed!
In the case of wooden floors, its construction will distribute the load from the beams around the entire perimeter of the walls and prevent cracking of aerated concrete from point loads.
The advantages of wooden beams are:
There are also negative sides to wood:
Despite such significant negative qualities, a tree is still chosen much more often, and here's why: special compounds for impregnating wood can extend its service life, protect it from decay and ignition. And low strength is eradicated by using more beams and reducing the laying step.
Now consider concrete floors and their disadvantages:
As you can see, all the shortcomings are connected only with the price. To make a final decision, check out the article about.
For the construction of floors between floors of a building, I usually use only three types of wooden beams:
We will figure out which of them are most suitable specifically for each design, highlight the disadvantages and advantages of each type.
Beams made of solid timber are distinguished by their strength, but they are inferior in the maximum possible length. In order for the beam not to bend over time, it is recommended not to install it longer than 5 meters. That is, timber floors are only suitable for small houses.
Of the significant disadvantages, one can single out the fact that, without proper processing, the floors can eventually begin to rot and become moldy. Do not exclude the risk of fire.
Attention!
Glulam beams have one undeniable advantage — their length without deflection can reach 12 meters.
Glued beams have the following advantages:
However, this material is much more expensive.
I-beams considered one of the most durable and reliable due to the shape of the profile, because they consist of several layers, each of which is protected by various impregnations.
The advantages of I-beams include:
The number of beams, their dimensions, the installation step depend directly on the area of \u200b\u200bthe room and the expected loads. Most experts believe that the optimal load on the floors is 0.4 tons per one square meter area (400 kg / m 2). This load includes the weight of the beam itself, the mass of the draft and finish coat floor above and ceiling below, insulation, communications, as well as furniture and people.
The best section for rectangular wooden beams is considered to be with a height to width ratio of 1.4: 1.
The cross section also depends on what kind of wood the floors are made of. Now let's bring average recommended values at a laying step of 60 cm:
If the step increases, then the size of the beam section should also be increased.
Here is a table of sections of wooden floor beams, depending on the span and installation step, with a load of 400 kg / m2:
span (m)/ |
2,0 |
2,5 |
3,0 |
4,0 |
4,5 |
5,0 |
6,0 |
---|---|---|---|---|---|---|---|
0,6 | 75x100 | 75x150 | 75x200 | 100x200 | 100x200 | 125x200 | 150x225 |

If it is not planned to load the floors (in case non-residential attic for storing light things), then lower load values from 150 to 350 kg / m 2 are permissible. Here are the values for the installation step of 60 cm:
Loads, kg/rm. m | Cross-section of beams with span length, m | ||||||

On the net you can find online calculators for calculating bearing capacity wooden beams. I will give a link to one of them: http://vladirom.narod.ru/stoves/beamcalc.html
Also, for example, you can replace one beam with a section of 100x200 with two boards 50x200, sewn together with bolts or nails every meter. They do this for various reasons:
It is recommended to stitch the boards so that the wood fibers are in different directions. This increases the strength of the structure.
Now, only three types of floors are mainly used:
The first option is standard, it was for him that the dimensions of the section were described. Ribbed and beam-ribbed ceilings are practically not used in the present due to the increased time of work and the complexity of the design, so we will not dwell on them.
The main stage is, of course, the installation of beams. It implies competent preparation at the stage of construction of the first floor.
At first the tree must be pre-treated fire-fighting compound, as well as liquid from decay(this must be done with the entire crossbar). This must be done immediately after purchase. If the material will lie for some time before laying, it must be shifted: a row of beams, then 3-4 bars across, then the next row. So the board will be ventilated and dry. This will prevent mold from forming.
The part of the beam embedded in the wall should also be covered with:
This is done due to the fact that wood in contact with concrete and blocks can absorb moisture and eventually begin to rot.
For aerated concrete, the maintenance moisture content of 3-5% is considered normal. No matter how dry the blocks seem, direct contact of wood with this material is unacceptable.
The beam must be embedded in the load-bearing wall by at least 12 cm. The ends are cut at an angle of 70 degrees in order to ensure the removal of moisture.
Attention!
Cut off the end of the beam waterproofing material no need. Otherwise, access to the evaporation of moisture will be closed. Required to leave a small air gap between the end of the beam and the wall.
The fastening of beams to the armo-belt in gas silicate houses is carried out with anchor bolts.
For insulation from the side of the street, a heater can be placed in front of the beam. As a rule, the outer ends of the beams from the outside are insulated with expanded polystyrene.
Filling the voids between the laid beams is done with gas blocks. Between the gas silicate and the timber, gaps of 2-3 cm are left. They are tightly clogged with mineral wool, thus preventing the formation of condensate and dampening of the beams.
Do not forget to consider the placement of the stairs to the second floor, since the opening must be provided immediately:
Well, that's all, the floors are ready. Now you can proceed to the next finishing.
Upon completion of the construction of the ceiling, it is recommended to wait before starting to carry out finishing work so that the beams shrink. Overlappings are recommended to be “hidden” behind a fine finish before the onset of cold weather so that they are not exposed to damp weather conditions.
You also need to make a roof. If this cannot be done before winter, then the entire structure should be covered with a film or awning material, including windows, so that moisture does not enter the building. But it is still recommended to leave small through “gaps” so that there is an optimal level of humidity inside the room.
Now directly to the post-installation finish. First, a draft ceiling is made from the bottom of the ceiling. It can also be made from plywood, if the construction of, for example, a false ceiling is provided for in the future.
You should start from the bottom of the beam, since insulation is usually placed between the ceiling and the floor, which also acts as sound insulation.
After installing the ceiling, insulation and vapor barrier are already placed on top (if necessary). For example, if the upper and lower floors are constantly heated, then insulation is not necessary. But it should be noted that insulation works and how soundproofing. If the second floor is an attic, then you definitely need to insulate - otherwise the heat will go away.
After laying the insulation, you can lay a subfloor (it will help in the further construction of the building, since you do not have to install scaffolding).
Fine finishing must be done after windows appear in the house and it shrinks.
Wooden floors are one of the most optimal solutions. After all, wooden beams are strong, light and at the same time cheap. They are easy to install and do not put excessive pressure on the walls. Main, correctly calculate and be sure to process a wooden structure.
To increase the strength of the structure, metal I-beams can be used instead of wood. In this case, you will need a crane for installation. And metal costs more than wood. And if you are ready for such expenses, then isn’t it easier then to opt for? Since the main advantage of overlapping on wooden beams in an aerated concrete house is cost savings.
Ceilings in a house made of aerated concrete are carried out, as a rule, along an armored belt. With all the unique advantages of aerated concrete, the strength of the blocks is too low to build aerated concrete houses higher than two or three floors. The overlap along aerated concrete walls is mounted on a design reinforced reinforced concrete belt, passing along the entire contour of the enclosing walls at the basement level, under each interfloor overlap and under the roof. Armor belts are necessary for an aerated concrete house not only as supports for beam systems. The floors of the house carry and redistribute the load on the supporting structures of the walls, and aerated concrete has a lack of fragility. Supporting beams on light porous blocks can lead to local punching, therefore, regardless of the type of overlap, armored belts are performed, including in order to increase the spatial rigidity of the structure.
The requirements for floors of houses made of aerated concrete take into account the insufficient compressive strength of aerated concrete (due to the cellular structure of the blocks). The cover must provide:
Types of floors for aerated concrete houses:
Various types of floors modern cottages, modern and expressive - tented, coffered, arched, brick vaults and others - for gas-block houses are too structurally complex and uneconomical.
The difference between an aerated concrete house is a necessity reinforced belts for any terrain, even if seismic phenomena in the construction area are completely excluded. The beam ceiling, regardless of the material of the beams, is always equipped according to the armored belt. The first stage of the armo-belt device is the alignment of the exact horizontality of the upper cut of the bearing walls, which is unrealistic in practice. All defects are eliminated by erasing the aerated concrete material until it is completely leveled, then the overlap is performed according to the technology.
Any type of overlap is possible, provided that the load calculation is performed. The optimal floor for an aerated concrete house is considered to be a similar floor from factory autoclaved aerated concrete slabs. But classic wooden beams are still more popular.
The difference in mass of traditional hollow and ribbed reinforced concrete slabs with aerated concrete slabs also determines the choice. For quick build Houses prefabricated ceiling optimal if there are conditions:
The slabs are mounted along the armored belt (options for brick pillows under the slab floor are possible if there is a calculation). The slabs are monolithic with a cement-sand mortar, the ends of the floor are thermally insulated.
Justified complex and time-consuming monolithic overlap for unique buildings of aerated concrete, complex in plan and/or having curved walls. Concrete is made on light aggregates (polystyrene, vermiculite), the reinforcement cage is calculated, usually at least two meshes - lower and upper. It also requires high-quality formwork for overlapping, inventory is best. Homemade board and board formwork requires deflection control and careful insulation, and is usually applied locally in small difficult areas. The total thickness of the slab is 150-200 mm, depending on the span, and each cm of thickening will greatly affect the total load on the aerated concrete walls.
Professional calculation for monolithic floors - required condition. In addition, in order to reduce and redistribute loads, they change the design: not a flat floor, but a ribbed one - with beams and thin layers concrete pouring. But this option is closer to the beam monolithic ceiling, since the efforts are perceived by the ribs-beams. The formwork is non-removable and includes reinforcing metal profile sheets. Concrete pouring must be continuous, cold joints are excluded. As for the laboriousness of manufacturing such a ribbed monolithic floor, it is considerable, as well as the cost, but for large-span cottages (9.0 m or more), this expensive type of non-standard floor is quite justified.
Advantages of monolithic floors:
To the minuses of monolithic concrete floors include:
A gas block house with a standard configuration and distances between bearing walls up to 6.0 m is traditionally covered with deck beams - metal or wood. Rolled metal for beams is quite an expensive material, and requires careful anti-corrosion treatment, and special equipment is needed for the installation of heavy profiles. Therefore, a wooden beam ceiling for a house made of aerated concrete is still in the lead among private builders. An important advantage of a wooden floor is the possibility of independent work.
Aerated concrete is used for the construction of buildings, the strength of which is determined by a number of factors. It is necessary to take into account the quality of the material used and determine the execution of the interfloor structure. Thinking about the construction of the floor of the lower floor in the house or the formation of a reinforced concrete base over the basement, you should figure out how to make floors in the house from aerated concrete. It is important to take into account the dimensions of the beams, the magnitude of the load on bearing bars and form a reinforced concrete base of the required thickness. Consider how the installation of plates is carried out.
Ceilings for a house made of aerated concrete are critical elements of the building. After all, the margin of safety of gas blocks does not allow the construction of buildings with a height of more than three floors, and aerated concrete loses in terms of strength characteristics ordinary concrete. That is why a set of requirements is imposed on the ceilings of aerated concrete structures.
The interfloor structure must have the following properties:
An important point is the uniform distribution of loads transmitted by floor slabs or the surface of the support beam to the main walls. To enhance the rigidity of the structure and equalize the efforts, an armored belt is constructed on aerated concrete. It is necessary for any wall thickness. Reinforced concrete edging along the perimeter of the box prevents cracking of the blocks on which the floor beams rest.
Thinking about the construction of a building envelope above the basement of the building and between floors, developers have to look for the answer to the question: “What floors are best for aerated concrete houses?”. Some believe that the optimal solution is a wooden floor, characterized by low weight, affordable price and maintainability. The main argument in choosing this option is the ease of installation of wooden beams.
However, there are limitations:
That is why it is advisable to give preference to a ceiling formed on a metal profile, or to choose an interfloor structure made of reinforced concrete.
When choosing an option, it is important to consider the results of the load calculation, as well as the following factors:
It is advisable to entrust the choice of overlapping option professional builders who will develop project documentation and correctly perform the necessary calculations.
Regardless design features floors for an aerated concrete house, the general algorithm of actions for the construction of an interfloor structure includes the following steps:
To ensure a long service life of the overlapping structure, it is important to choose the right type of overlap and comply with the requirements of the technology.
Each variety interfloor overlap has its own characteristics.
For a building constructed from aerated concrete blocks, the following options for overlapping structures are used:
Let us dwell in more detail on each option for overlapping.
Using standard floor slabs for aerated concrete houses, it is easy to build a separating structure over the basement part of the building, as well as between floors, in a limited time. Quantity reinforced concrete panels determined by the size of the building. It is important to choose the right slabs, taking into account the span. In this case, the size of the supporting surface on the aerated concrete wall must be at least 15 cm in accordance with the requirements of building codes and regulations.
Panels are used to form the floor various designs and sizes:
Laying is carried out on the planned surface of aerated concrete walls. A thin layer of cement mixture is applied to the end plane.
Advantages of the prefabricated option:
Design cons:
To improve the heat-insulating and noise-protective characteristics, the internal cavities in the slabs are filled with mineral wool.
Monolithic ceiling is built directly on construction site. The process of erecting a solid structure is quite laborious, however, it is indispensable for a non-standard configuration of the structure. Developers are attracted by the fact that the monolithic floor in the house made of aerated concrete does not have butt joints and is different flat surface.
The sequence of actions for the construction of a monolithic version:
The technology allows the use of a metal profile for the construction of formwork, which greatly simplifies the work and allows you to form a flat ceiling surface.
Advantages of one-piece construction:
TO weaknesses relate:
The one-piece option is in demand when it is necessary to concrete the ceiling in a building of a non-standard shape.
Prefabricated-monolithic technology allows you to form floors different ways:
The second method, which does not require the use of lifting equipment, is more preferable. It has a number of advantages:
With the help of granulated expanded clay, mineral wool or polystyrene foam sheets, high thermal insulation characteristics are provided. For the construction of the ceiling by the prefabricated-monolithic method using polystyrene concrete blocks, it is necessary to correctly calculate the distance between the beams, taking into account the dimensions of the blocks.
Beam technology allows you to quickly build ceilings in small aerated concrete structures based on the following elements:
The first installation method does not require significant costs, unlike the expensive method using a metal profile.
The beam ceiling construction technology provides for:
Advantages of a beam ceiling:
Technology cons:
Despite the shortcomings, the beam method is popular in private housing construction.
Prior to commencement of construction activities, it is necessary to determine constructive option and learn how to make floors in aerated concrete house according to the requirements of the technology. It is necessary to take a responsible approach to the performance of work, the quality of which determines the stability and durability of the aerated concrete structure.
