Installation according to the importance of the structure, the characteristics of the load, the form of the weld, the working environment, and the stress state
When installing the steel structure, pay attention to the following problems:
1. Before the
steel structure is installed, all components should be performed for multiple inspections, such as whether the number, length, verticality, and size between the bolt holes at the installation node in the component meet the design requirements; Deformation should be corrected on the ground and properly solved.
2. The steel column and the foundation generally use the embedded anchor bolt connection. Therefore, the size of the pillar scoop bolts should be checked before installing the steel column, exposing the length of the basic surface, whether the elevation of the basic top surface meets the design and play, and the column Whether the threads of the foot anchor bolt are damaged (usually measured during infrastructure to protect the pillar anchor bolt and its threads are not damaged).
3. When the steel structure is lifted, it should be taken to prevent excessive bending and deformation. The same corresponding corresponding to the contact part of the contact site of the rope and the component to prevent the engraving component.
4. After the steel structure is lifted, it should be tied to support and other connected components in time to protect the stability of the structure.
5. The lifting of all the upper structures needs to be carried out in the lower structure, correction, and fastening the supporting components before it can be carried out.
6. Depending on the construction capacity of the construction site, assembled into a larger installation unit on the ground to reduce the workload of high -altitude operations.
