Steel structure staircase production and installation
The use of steel structure assembly spiral staircase, indoor staircase, steel staircase with less fulcrum, high bearing, modeling, high technical content known, not easy to be affected by columns, floor structure, solid. The staircase is made of square pipe, round pipe, Angle iron, channel steel, I-steel, etc., with a variety of shapes. Staircases should be designed with spatial integrity in mind. It is best to design the location of stairs on the basis of not destroying the integrity of each functional space, that is, to consider the functional space of 2 floors at the same time
Because of the characteristics of steel staircase, its application is also very wide. It can be used for outdoor facilities such as street overpasses and subway handrails, as well as indoor facilities such as restaurants, factories, warehouses, gymnasiums, large markets and leisure resorts.
The calculation of steel stair (steel structure stair) mainly includes load calculation, internal force calculation, section calculation and bearing capacity calculation. The safety of steel frame stairs (steel structure stairs) is the primary consideration, so in the design of steel structure stairs, safety work should be put in the first place.
This project is the production and installation project of spiral staircase and balustrade. The height of steel structure spiral staircase is increased to 3.75m in the northwest corner of the atrium on the first floor underground, and 20mm stone is laid on the stair steps and platform. 20m of new balustrade stair handrail is added, about 350m of atrium balustrade on the first and second floors, and about 60m of outdoor balustrade.
This project is a new outdoor steel staircase project for the elderly apartment in Chaoyang. Due to the use needs, a new steel fire staircase is needed outside the two buildings. The construction photos are as follows:

This project is a house renovation project. According to the owner's interior renovation of the villa, the original hole should be blocked, hydrodrill static cutting of the hole, steel reinforcement of the hole, new beams and plates, and steel stairs
This project is a new steel structure staircase project between buildings, the project is located in Changping District North seven, in building 1, building 2 each steel structure staircase. Floor 1 to Floor 5, Floor 2 to Floor 8. Contract projects: from design to processing plant disassembly drawing, to site installation, etc. The construction is as follows:
Steel structure workshop is a kind of steel structure, steel structure workshop has the characteristics of short construction time, low cost, practical and so on. Because our steel output increases, many have begun to adopt steel structure. Steel structure plant is divided into light and heavy steel structure plant
Steel structure factory building is generally a space system composed of roof structure, column, crane beam (or truss), various supports and wall frame. These components can be divided into the following categories according to the role they play
1. Horizontal framing
2. Roof structure
3. Support system (roof part support and support between columns: bearing connection)
4. Crane beam and brake beam (or brake truss)
5. Wall frame
- Advantages of steel structure:
1. Wide use: can be used in factories, warehouses, office buildings, stadiums, hangars and so on. It is suitable for single-storey large-span buildings, and can also be used to build multi-storey or high-rise buildings.
2. Simple construction and short construction period: All components are prefabricated in the factory and simply assembled on site, thus greatly shortening the construction period. A building of 6000 square meters can be basically installed in 40 days.
3. Durable and easy to repair: Steel structures designed for general purpose computers are weather-resistant and require minimal maintenance.
4. Beautiful and practical: the lines of steel structure workshop are simple and smooth, with a modern sense. The colorful wall body panel is available in a variety of colors, and the wall can also be made of other materials, so it has more flexibility.
5. Reasonable cost: steel structure light weight, reduce the foundation cost, fast construction speed, can be built and put into production as soon as possible, comprehensive economic benefits are much better than concrete structure building, using steel structure can save 30% steel structure plant cost.
The installation process depends on the quality of the steel structure workshop project. Each step of the installation process of the steel structure workshop is strictly controlled, and the next step can only be carried out after the acceptance of each process.
Steel structure plant features:
Steel structure plant has the advantages of overall light, saving foundation, less material, low cost, short construction period, large span, safe and reliable, beautiful shape, stable structure and so on. Steel structure plant is widely used in long-span industrial plant, metal and plastic, mechanical equipment, printing paper products, mold and other industries. Warehouse, cold storage, high-rise buildings, office buildings, multi-storey parking and residential construction industry.
Note:
1. Pay attention to the positioning of anchor bolts during construction.
2. Repeatedly compound the axis positioning and perpendicularity of each steel column
3. Processing of connection joints between steel column and steel beam or tie rod
