Support and stretching are usually round steel tiles, which can be divided into two types, one is single tile (color steel tile). Both are composite boards. (Polyurethane or rock wool is sandwiched between two color-coated boards, which helps to keep warm in winter and cool in summer, sound insulation and fire prevention.) Light weight, high strength, and large span: Although the steel structure workshop has a higher density than other building materials, its strength very high. Under the same stress conditions, the steel structure has a small self-weight and can be made into a large-span structure.
Short construction period: The construction part of the steel structure workshop is mainly prefabricated in the factory, and the installation is stopped after being transported to the construction site, which is convenient for assembly and construction. High refractoriness: When the surface temperature of the steel is within 150℃, the strength does not change much, and when it exceeds 150℃, the strength decreases significantly.
Generally speaking, fire retardant coating is applied on the surface of steel structure workshop to form a protective film and improve the fire resistance of components. Of course, it is also very important to reasonably divide the fire functional area and use fire shutters. Anti-seepage and waterproof: Rainwater penetrates mainly through joints and gaps. In order to prevent leakage and waterproofing, it is necessary to use a gasket at the screw port, then covertly fix it, use sealant and welding on the overlapping part of the board, remove the overlapping part with the full-length board, and use expansion waterproofing treatment on each joint.
The design of the steel structure workshop node determines the safety of the industrial building, and the design of the node must fully consider the rationality and the safety of the building.
