How to Build a Light Structural Steel Workshop
Light steel structure is a new type of structure developed on the basis of ordinary steel structure, which includes all steel structures used under light roofs.
Compared with ordinary steel structure, it has better economic indicators. The light steel structure is not only light in weight, low in steel consumption, and fast in construction speed, but also has strong seismic resistance and can improve the overall seismic performance of the entire house. It is a structure that is currently widely used in industrial plants.
Form and characteristics of rigid frame
1. The lightweight roof made by the BMS rollforming machine can not only reduce the cross-sectional size of beams and columns, but also reduce the foundation accordingly.
2. In a multi-span building, it can be made into a large double-slope roof with a ridge, which creates conditions for long-slope drainage. The middle column can reduce the span of the beam, thereby reducing the cost. The middle column adopts the up and down hinged swing column made of steel pipe, which takes up a small space.
3. The lateral rigidity of the rigid frame Made by BMS roll forming machine is ensured by the support of the purlin, eliminating the need for longitudinal rigid components and reducing the width of the fl**ge.
4. The rigid frame can adopt variable cross-section, and the cross-section is proportional to the bending moment; when the cross-section is variable, the height and thickness of the web and the width of the fl**ge can be changed according to the needs, so as to make the best use of the material.
5. The web of the rigid frame that made by BMS roll forming machine can be designed according to the effective width, that is, part of the web is allowed to lose stability and its strength after buckling can be used.
6. The vertical load is usually the designed control load, but when the wind load is large or the house is high, the effect of the wind load should not be ignored. In the portal frame of light roof, the seismic effect generally does not have a controlling effect.
7. BMS roll forming machine makes the support lighter. Connect it to the web directly or with a horizontal gusset plate. Tensioned round steel can be used.
8. The structural components can all be made in the factory, with a high degree of industrialization. The component units can be divided according to the transportation conditions, and the units are connected by bolts on the spot, which is convenient and fast to install, and the amount of civil construction is small.
