Hoisting function of seismic support
Importance of seismic support for buildings seismic support can play an excellent role in structural maintenance of buildings.
1、 To be smooth and stable: when the composite seismic support with guaranteed quality stops installation, it is not only necessary to ensure that the support is firmly fixed, but also the position of the support should be calculated accurately. After installation, it is necessary to ensure the flatness, and also close contact with the supporting pipeline, so that it can play an excellent seismic role.
2、 No jamming phenomenon: the combined seismic support has many different categories. Assuming that the required installation of the guiding and sliding seismic support, the installation position should be offset from the center of the maintenance surface to the purpose of the opposite displacement. The sliding surface of the seismic support should be kept clean and flat. During the sliding process of the support, there should be no tilting and jamming phenomenon.
3、 Welding treatment shall be qualified: since there are many components in the combined seismic support and hanger, and the support and hanger need to be welded, qualified welders shall be responsible for welding treatment, and the center of the required welding shall be free from missing welding, lack of welding, welding cracks and other defects. At the same time, When the pipeline is directly welded with the seismic resistance, the pipeline shall not show undercut and burn through.
4、 The temporary support shall not be in dispute with the formal support: when the temporary support is assumed to be selected first during installation, the temporary support and hanger shall not be in dispute with the position of the formal composite seismic support, and obvious signs shall be made to distinguish them. When the installation is completed, the temporary support shall be removed.

3、 Strengthen the foundation of common sense, technology and progressive implementation.
Common sense and technology are supplied by personnel. It not only shows the talent demand for completing tasks, but also shows the power and quality of completing tasks.
Therefore, the examination of a person's common sense and technology is not limited to his ability and quality, and it should be evaluated in terms of time, cost, quality, and impact on the surrounding environment. Similarly, the time it takes to end a thing is different, the cost is used up and down, the quality of the end is good or bad, the use of capital is different, and the impact on the surrounding environment is good or bad.
Therefore, the evaluation of him and his talents should be multidimensional. Modern society is a society that pays attention to power.
The successful operation of any project has its time and capital needs, which should be put into a system to pay attention to. If one task cannot be completed, the next task cannot be carried out; Failure to complete one policy will affect all policies.
This puts forward higher demands on our practitioners in terms of common sense and technology. This should lead us to pay great attention to it.
