  • Many details need to be considered in the design of steel structure buildings, such as: appropriate structural damping ratio, rigid column foot design, beam and column rigid connection design, floor design and so on. Next, I will tell you the details of steel structure building design.

  • The horizontal height is measured with laser level, the bottom line of the horizontal structure is drawn, the leveling layer of the ring beam channel steel and embedded steel plate is removed, the embedded steel plate is fully connected with the load-bearing wall, and the firm degree, tension and stress are increased. After the material enters the field, carefully remove dirt and rust, and apply anti-rust paint. Fixed embedded steel plate and ring beam: drill with impact hammer, blow dust with compressed air pipe, and then put into chemical structure rubber hose, insert chemical anchor bolt into the hole with power tools, wait for curing time, and then install embedded steel plate and ring beam channel steel. The setting time of chemical rubber hose is generally more than 30 minutes.

  • The processing and installation of steel grid structure engineering. Steel grid is a spatial structure made up of multiple bars connected by nodes according to a certain grid form. Due to its advantages of space force, light weight, high stiffness, good seismic performance and so on, it is widely used in the roof of the stadium, cinema, exhibition hall, waiting hall, stadium and other buildings. Let's understand the construction and installation process of steel grid structure engineering.
