Stringers are adopted according to Series 1.050.9-4.93, issue 3, wall and front beams - according to Series 1.050.9-4.93, issue 3
Element interface units - according to Series 1.050.9-4.93 issue 0-1.
The order for the steps must specify that all main stages LS-12 and LS-15 must have M 1 embedded parts for fastening the racks stair railing taking into account the option of stairs with clockwise rise. Staircase landings are designed according to Series 1.050.9-4.93, issue 0-0. BNB 5.03.01-02
The stringers are attached to the platform beams using M16 bolts. After checking the correct position of the mounted structures, the bolt nuts must be secured by welding them to the bolt rod, or by hammering the threads.
Welding is carried out using electrodes E-42 hshv.=6mm according to GOST-5264-80.
Stringers and beams are covered with steel woven mesh 1-R-12-1.6 GOST 8536-80 and plastered with cement-sand mortar M50 25 mm thick.
The beams rest on the rear mounted on a monolithic belt
Specialized design programs significantly save time when developing drawings, calculating the main dimensions of structures, and drawing up accompanying documentation for products. In addition, using the programs, there is no doubt that all design stages will be carried out in compliance with existing SNiP and GOST standards. The article will help you understand how to build a staircase in AutoCAD.
Modeling
The program allows you to design structures for any purpose, even for a beginner who does not have much experience in using the system, which includes:
The program has its own data library, which includes regulations to select a design, its parameters or SNiPs, and the rules for constructing the model. A series of regulations includes the basics of constructing metal structures, GOST standards for the materials used, fire safety requirements and basic urban planning rules.
The documentation or series regulates the basics of constructing structures and fencing for them, provides rules for proper installation of products and operation, and contains a list of additional elements.
Drawings made in AutoCad must comply with certain rules:
To develop a drawing “for yourself,” these are the basic provisions for working with the program.
Initially, you should choose the type of its design and material of manufacture.
Types in AutoCad
Types shown in the photo:
The choice of type is influenced by:
The choice of material depends on the capital of the house and the degree of its fire resistance. The most convenient design, which ensures the safest ascent, is flat with one flight, with 15 steps.
How to draw in AutoCAD
When virtually creating a structure, ready-made blocks are used that are offered by the program - they can be edited by setting the required parameters. The composition includes several basic elements.
These include:
Blocks for AutoCAD
In AutoCad, drawings are created by drawing up and selecting parameters for each specific element. The versatility of such computer software allows you to carry out and calculate in advance absolutely any design with or without a platform.
Elements of marches with platforms
The entire drawing is developed in section, which allows you to carefully view all selected elements. Each of them in the drawing shows not only the structure itself, but also all the main dimensions.
A set of ready-made documentation, which was developed in the AutoCad program, includes longitudinal and cross section objects, specification with the necessary fasteners. Everything is done in compliance with the relevant GOST standards.
Marches and nodes in AutoCad are carried out in accordance with GOST 9818-85.
The steps for them can be:
In this case, the flat ones are installed on the slab, and the ribbed types are installed on the stringer. At the same time, LMP flights have a large-sized structure, united together by a slab.
For each type of structure, a site is selected, included in the program.
Tip: You should pay attention to the turn - it can be right or left.
Wiring diagram
As an example, we consider the most complex option - creating a structure in the AutoCad program. In this case, the steps from bottom to top are placed around a common post.
The user sets the radius on the screen, in the absence of restrictions on the trajectory of the model. In another case, the radius must be determined taking into account the given length of the tread and the parameters of its shape. To get the desired radius, you should adjust the tread length.
Initial design stage
To create a model of a given tread width according to midline(T), you need:
Design
Tip: Before selecting tools, to display the Properties palette, you need to click sequentially: the “Home” tab, then the “Creation” panel, then the “Tools” drop-down list and Properties.
After that:
The video shows the construction of any structure in more detail.
Modern technologies can significantly save time on drawing development, wiring diagrams for metal structures, for the necessary calculations. The program allows you to get acquainted with all angles in 3D projection staircase design, see its location in the space of the room. By designing a section based on the model, you can get an idea of its design, internal structure the entire building.
Application of specialized computer program allows you to significantly simplify and speed up construction in AutoCAD. However, if possible, better process entrust the development of drawings to a professional. The cost of even a small mistake turns out to be too high, because the staircase is one of the most important components of the building.
In order to carry out a competent, correct calculation of the stairs, it is possible to use the special AutoCad program, which will greatly help and save time.
The use of specialized design programs significantly saves time in the process of preparing drawing documentation, as well as in calculations. In addition, using the programs, you can be sure that the design is made in accordance with existing building codes and GOST standards.
Thanks to AutoCad, even a beginner can design a metal staircase for any purpose, without any special knowledge of the program. AutoCad systems and equipment include ready-made components for the design of metal staircase structures, industrial and domestic use, fire escapes, and also contains information about installation and installation.
Based given parameters buildings, using AutoCad you can make a drawing of a metal structure of any configuration, and, importantly, in accordance with fire safety standards.
The staircase structure will be “built” from ready-made blocks offered by the program, which can be edited by setting the necessary parameters.
Metal staircase consists of several main elements:
In the program, the drawing will be created by compiling and selecting the parameters of each specific element. Thanks to the versatility of such computer software, it is possible to design and calculate in advance absolutely any metal staircase with or without a platform.
The entire drawing will be presented in a section so that you can view the selected element more carefully. Each selected and approved element in the drawing is presented not only structurally, but also all the main dimensions of flights of stairs or flights are shown.
The set of ready-made documentation, made in AutoCad system, there will be not only a longitudinal section of the constructed objects, but also a transverse one, as well as a specification with the necessary fasteners and the corresponding GOSTs.
Flights of stairs in the program are carried out in accordance with GOST 9818-85 and can be of the following types:
Flat and ribbed types have one significant difference: some are installed on a slab, while others are installed on a stringer. LMP staircases are more large structures, which are joined together by a slab.
For each type of staircase structures, according to the articles included in the program, it is selected landing, for example, marching type or ribbed.
Need to pay Special attention for turning the staircase structure - it can be made in two versions: right and left.
The AutoCad program has its own data library, which includes regulatory documents and construction rules. Such documentation, on the basis of which drawings are constructed, is called a series. The series of regulations includes not only the basics of constructing a specific metal structure, but also GOST for the material used, fire safety and rules of basic urban planning.
For example, to build metal stairs with a platform, you should take Series 1.450.3-7.94 Metal stairs, platforms, fences as a basis. Issue 2.
There are issues 0-2, which characterize the material used, so issue No. 2 involves the design of structures from hot-rolled profiles.
Documentation - series, regulate the basics of construction and installation of steel stairs, railings for them, and the necessary knowledge for their proper installation and operation, as well as a set of additional elements.
Railings and railings are used in the construction of stairs, which are installed with floor heights from 3 to 4.5 meters, erected under standard construction conditions.
Also, stair railings are applicable for reconstruction of residential buildings with floor heights of 2.8 meters.
Specialized march fencing is designed taking into account standard sizes buildings of series 1.251.1-4, issue 1 and series 1.252.1-4, issue 1 and stairs of individual steps according to GOST 8717.0-84 and GOST 8717.1-84.
Also, the products of this release provide fencing for staircase structures at entrances to basements.
Fire escape, unlike standard ones metal structures, is carried out in accordance with certain norms and standards, based on where it will be located:
External stairs are most often lightweight, small-sized structures, the steps and railings of which are made of special reinforcing steel. This is done in order to eliminate possible troubles with accumulated snow in winter time, as well as to facilitate the design. Fire escapes installed on streets must be treated with a special anti-corrosion compound. This is due to the need to extend the service life of the metal structure.
Metal fire escapes installed inside the house are intended mainly to evacuate the population, so the handrails and steps must be as safe and fireproof as possible. For this purpose, a special fire-resistant coating is used.
A drawing made in AutoCad must meet certain standards:
The beginning of construction must begin with the axial and bearing lines that run in the middle of the stairs.
The section of the staircase structure must be made in such a way that all bevels and bends are visible.
The staircase structure must be tied to the walls.
It is necessary to mark (with dimensions) the level line of the floor, ceiling, second floor, attic floor.
Outside the outline of the main drawing, dotted markings of window and door openings are placed.
If the drawing is done “for oneself”, for self-made stairs, in the future, such simple basics will be enough to work with the program.
To start building a staircase structure, you need to set the initial parameters:
To the benefits modern technologies significant time savings can be attributed to the execution of drawings, diagrams, plans, as well as the necessary calculations. In addition, the program allows you to see 3D projections, examine all the angles of the staircase structure, its location relative to the space of the room.
Not only professionals, but also beginners can use such a program. Having started to build the stairs yourself, you should resort to the help of computer technology.

When not one floor, but two or three are planned in a residential building, it is imperative to think through the structure that will lead to the upper tiers. A drawing of a metal staircase, created based on measurements, will help facilitate the work and make the arrangement process accessible.
Schemes and drawings of metal stairs
The design of a metal staircase has all the necessary safety and durability parameters. That is why they often rely on this type of product. Metal is practically not susceptible to corrosion, it advantageously emphasizes the style of the room and brings rigor and elegance to the design. Looking at a wide variety of the proposed metal stairs, one can understand that even a person who has no experience in such incarnations can make them with his own hands.
Drawing with dimensions of a metal staircase The most important thing is to choose a design that will be feasible to draw, prepare and install in the space of the room or outside it.
Based on the priorities and shortcomings of the material and design as a whole, you can bet in favor or against such a decision.
It is much easier to make a drawing of a metal staircase if the structure is equipped with the help of stringers. This is due to the fact that you need to calculate the distance for each step and prepare the material that will subsequently be fixed to the base. Stringers are the base (foundation) in the form of a future staircase. 
It can be made from different materials and be secured as required by the premises. Of course, to purchase suitable stringers, measurements are still required.
After all, the design must fit the parameters of the space allocated for the stairs. A ladder on metal stringers will help even inexperienced craftsmen complete the installation task.
The main thing is to correctly mark the place where the gangway will be located. And also have on hand the tools and materials necessary to implement this idea in your own home.
Metal staircase design option Due to the fact that gangways equipped with stringers have earned their vocation, positive sides such a solution is obvious:
These are not all the positive aspects of staircases on stringers; each owner of a private house finds his own independent advantages.
It is necessary to correctly determine the size of the base for the steps so that the structure fits clearly into the interior. It is not difficult to make such calculations. Simply measure the height, angle and width of the required installation.
Make your own drawing of a metal staircase with my own hands simple enough. To do this, you need to take measurements of the space in which the steps leading to the second floor will be located.
In order to measure space, you should have the following accessories on hand:
This is a minimum set of accessories that will help you carry out the measurement process efficiently and quickly.
To make the diagram as accurate and correct as possible, you should also prepare a number of stationery items. Namely:
You should draw the diagram carefully and carefully so that during the actual installation process you do not make errors that are difficult to correct.
In order not to make a mistake and correctly make a drawing with your own hands, you will need to make the following measurements:
After taking measurements, you can transfer the recorded parameters onto a sheet of paper, forming a diagram of future gangways.
When taking measurements, be sure to pay special attention to the following factors:
It can be different, but each of them is worthy and we often choose. The designs of metal stairs are:
| Screw | Such gangways will help maintain maximum usable space in room. The steps will highlight the sophistication of the design and add a spark to the big picture interior space. The only thing that can stop you is the difficulty of implementing the drawing yourself. Without special skills, a person cannot cope with the measurements necessary for such complex design. And also the direct process of installing stair structures requires some skill and skill. Knowing all the features spiral staircase, a person will be able to implement the idea of installing such a structure in a gangway. After the implementation of the plan, the interior will immediately sparkle with new colors. |
| Marching | This option is most often used to implement the idea of installing staircase structures. For such an array it is easy to draw a diagram even for those who have never encountered such a task before. Marching stairs can be straight, leading to the second floor or with turns (this helps to save space). Measuring the parameters required for drawing any of these types of gangways is very simple. Enough to have on hand necessary tools and devices. Direct installation of the structure is also elementary. You just have to stick to it step-by-step actions, which can be read about in any thematic literature. |
| Mounted | There are structures leading to the second floor that are supported on the wall. No supports are installed under such structures. The main load-bearing and load-bearing structure is the wall. Therefore, before proceeding, you should make sure that the walls are strong and ready to withstand such high load. If yes, then you can safely equip a hanging metal staircase. Such a staircase will help save space and make the style of the room elegant. |
Stairs are load-bearing structures of a building that serve for vertical communication between floors. When designing a staircase made of stacked reinforced concrete steps on steel stringers, it is important to pay special attention to the connection between the individual parts of the staircase.
If load-bearing structures flight of stairs and the interfloor platform are channels, they can be connected using a mounting element made of hot-rolled angle, to which the load-bearing structures are attached by welding.
Using standard parts from the GraphhiCS SPDS database, you can quickly draw the junction of the staircase to the interfloor landing (If you have not yet installed this program, you can do this using ). A drawing created in this way in AutoCAD will be dynamic, i.e. easy to make changes.
