The technical process of steel structure engineering construction

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.

After the installation of the ring beam, the joints shall be strengthened and welded; Separate the spacing of I-beam and measure the specific size of main beam with the error no more than 4mm. I beam blanking processing, spot welding after installation, reinforcing full welding; Separation of auxiliary beams, measurement, cutting, assembly, spot welding and full welding. Welding rebar is particularly important. After 360 degree welding, secondary welding is performed. After the completion of the steel structure project, such as laying wood or steel plate, the protruding part of the spot welding joint on the upper horizontal surface should be polished and polished, and the anti-rust paint should be brushed twice; If it is a steel-concrete structure, the pressing steel plate should be laid directly, welded on the I-beam, woven steel mesh structure, poured light concrete, and brushed with secondary anti-rust paint. Steel structure in the assembly process does not need a lot of manpower and material resources, assembly is convenient. Assembly can be completed in a short time and put into use as soon as possible. That's why so many people now choose steel structures. In addition, it has a high cost performance and running speed, effectively reduce the cost.

At present, steel structure engineering is very popular, many industrial plants, production workshops, exhibition halls, hotels and shopping places are using steel structure to achieve the function of the layer.
