How to choose materials for steel structure villas in Chongqing

In the design of steel structure villas, choosing a reasonable steel structure villa is also one of the cost savings of steel structure engineering, because steel structure villas make full use of high-efficiency section steel, such as flange-rolled steel width H and thin-walled and thin-walled, to achieve greater economic benefits. Benefits such as: Steel structure villas choose 1.H steel and T steel: Due to the thicker flanges and sturdy parts. It can be used as a separate component in steel structures (beams, columns and lattice ropes, etc.) without combined machining. Construction works can be reduced by 1/2-2/3; when used as lattice ropes, the storage of reinforcement panels and filler panels (or splice panels) has better economical results. 2. Thin-walled steel. It is suitable for ordinary steel structure platform beams, wall frame beams, lightweight floor coverings and ceilings, etc., saving 14%-20% higher than ordinary steel. The choice of steel structure villa 3. Steel pipe (Cao round pipe and square pipe): For axial compression members, this is especially economical, because when the cross-sectional area is the same, the turning radius of the steel pipe is larger. It is more suitable for steel structures such as tower structures and roof structures. When used in roof lattice structures, about 10% of steel can be saved due to the reduction of stiffeners and reduced section economy. Steel savings of 25% when using round inclined steel tube supports. In addition, in the environment of corrosive gas, it is more advantageous to use the steel pipe structure. 4. Cold-formed steel: Mainly used in steel structure villa projects, the thickness is generally 2-6 mm, which can save 10% of the steel buckle. Steel structure villa sandwich manufacturing method: Steel structure villa material selection 1. According to the design of the drawings, the steel components used in the factory prefabrication will be removed, polished and coated with anti-oxidation paint. 2. Use the laser level to measure the highest point, then find the reference point, measure the horizontal line of the steel structure and display the standard position line on the wall. 3. The rear wall of the pre-assembled steel plate is slotted and has a shovel (leveling layer), and the wall skin on the back of the frame is also peeled off. 4. Embedded steel plate is fixed. The steel structure villa is made of material 5, and the frame is fixed. 6. Install the main beam. 7. Installation of auxiliary beams for steel structure villas. 8. Install cement press plate and steel base plate. 9. Placement and arrangement of steel bars and concrete poles.
