Installation of steel components in steel structure engineering construction

Today to introduce to you about the installation of steel components in the construction of steel structure engineering, a total of eight summary, let's have a detailed look together.

1. Review the specification, positioning size, elevation and exposed length of embedded bolts, and confirm the age of embedded concrete. Check the consistency between the number of the components on site and the design against the drawing to prevent misassembly.

2. Investigate the operation site, determine the route of the crane, and formulate the hoisting implementation plan.

3. When installing high-strength bolts, the bolts should be able to freely penetrate into the hole, and can not be reamed at will. High-strength bolts can not be used instead of temporary bolts.

4, choose 16T wheel crane as lifting machinery.

5. The steel column is lifted by one or two points, temporarily fixed after being in place, and fixed after correction.

6. The steel beam adopts two-point lifting method. Before hoisting, the lifting point should be determined in advance and test lifting should be carried out to ensure its stability. The steel beam shall be temporarily fixed after hoisting, and the horizontal support shall be installed and fixed after checking the verticality.

7. After the installation of the overall frame, the frame should be installed again to check the correctness of the installation of all components, whether the connecting parts have been fastened, and whether the overall bending degree is within the deviation specified in the specification.

8. After the steel frame is checked and correct, the concrete of the column floor shall be timely poured by the civil construction unit, and the concrete shall be expanded concrete. Finish paint construction of steel members can also be implemented.

The above is our introduction to the installation of steel components in the construction of steel structure engineering.
