Before construction of steel structure, measure the overall structure level and pop out horizontal lines on the wall. If there is a screed, be sure to remove first. The purpose is to bring the frame beam close to the load-bearing wall. Conducive to stress, then draw the exact location of each bolt hole. After drilling a suitable hole with a hammer drill, empty the remaining ash inside the hole, insert a chemical hose, drill a chemical screw with a power tool, and wait for the chemical reaction to cure. This time period usually takes more than 30 minutes and is appropriate. After curing time, tighten the frame, tighten the screws, spot welding screws to prevent the frame from loosening.

In steel structure, industrial steel is used as the main bearing beam to connect the support points at both ends of the main beam. The construction of industrial steel should be reasonable, and it is the part with great force in the construction of the whole structure; In the process of lapping the main beam, the screed of embedded steel plate must be removed first. Cement wall skin, then fixed embedded steel plate. At the same time, the steps are basically the same as the framework building process. The measurement of the main beam is very important, and the error is less than 4mm. The main beam overlaps to a certain extent. Full welding, both ends of the main beam 360℃ full welding, industrial steel vertical placement, the force is the same.

The main beam structure of the sandwich steel structure is made of H-beam made of Q345B. A steel floor should be laid on the main structure, followed by pouring 120-200mm thick concrete behind the rebar.

Steel column is one of the main components of steel structure plant. Steel column, as the name suggests, is a column made of steel. Its section forms have two kinds -- solid belly column and lattice column. As for the steel column device, after the purchase part enters the field, the components shall be reinspected during the installation, and the attributes such as serial number, size, shape and connecting square hole shall be corresponded to the drawings one by one before the device construction of the components can be carried out.
