The light steel structure parts of light steel villas are manufactured with a high degree of factoryization and mechanization, and a high degree of commercialization. The construction speed of the site is fast, and it will not affect the nearby residents to facilitate civilized construction. Structural buildings are environmentally friendly and sustainable products. Light weight and good seismic performance. The comprehensive economic index is not higher than the reinforced concrete structure. Compared with brick-concrete houses, it can avoid the waste of resources caused by using soil to burn bricks. Because the wall thickness is smaller, it can increase the effective use area than brick-concrete structures; compared with reinforced concrete houses, light steel structure steel can be recycled in the future Use. Good seismic performance. Since the earthquake activity is left and right and up and down, the light steel structure connected by screws forms a safe and stable box, which will not cause the wall to collapse or the floor fall to endanger personal safety due to the shaking of the earthquake.
