Construction process of steel structure building

Steel structure building has good stability, short construction cycle and low cost. It is a building form with high cost performance at present. Next, let's briefly introduce the construction process of steel structure buildings.

1. Foundation construction.

No matter what kind of building, it should start from the foundation. The steel structure building has light self weight, simple foundation treatment and less soil during foundation construction. The foundation is mainly reinforced concrete strip. The connection between steel structure and concrete foundation adopts 10-12 ground angle bolts and is embedded along the bearing wall with a spacing of 1.2m to 1.5m.

2. Component production.

After the architectural design drawing of steel structure is drawn, it will be sent to the factory to produce the main frame and components of steel structure. Generally, it can be directly sent to the site for assembly after production.

3. Dragon frame installation.

After the foundation is completed, the waterproof treatment shall be carried out, and then the Dragon skeleton can be installed. Generally speaking, the light steel keel adopts double-sided aluminum zinc plated steel, which has good toughness and ductility, ensures the seismic performance of the house and improves the overall safety performance of the house.

4. Truss structure installation.

The truss structure of steel structure building is located between floors, which is the guarantee of the stability of the physical system of steel structure. Generally speaking, the area of components and the thickness of enclosure structure are relatively small, which can increase the service area of the building.

5. Wall construction.

The wall of steel structure building is composed of installation function board, which has different types such as fire prevention, waterproof, noise prevention, thermal insulation, decoration and so on. In addition, the wall process combines civil engineering technology and fire-proof and moisture-proof insulation technology, which can pre install the water and electricity pipelines in the wall.

6. Roof treatment.

The roof treatment of steel structure building is to add sunscreen and waterproof layer, and finally cover with tiles. After completing these basic work, you can choose building exterior decoration materials, such as exterior wall sealing plate, which can not only improve the integrity of the structure, but also have aesthetics.
