Our knowledge of seismic supports is limited to understanding, far inferior to those professionals. Nowadays, there are no particularly strict regulations or standards for the installation of seismic supports. We cannot judge whether the deepening treatment of seismic supports is reasonable based solely on a calculation sheet issued by the design party or the client. Some clients may try to minimize the use of seismic brackets in the early design stage in order to obtain the bidding documents, but in the later deepening stage of seismic brackets, they may communicate with customers to increase the number of seismic brackets. How can this be avoided? These issues are troubling us, who have limited knowledge about seismic supports.

It is generally recommended to adopt intelligent design. Design standards need to be issued before the installation of seismic supports. And we can communicate with the design party or party A to request optimization of the seismic support pipeline before the design drawings are released. The advantage of communicating in advance is to ensure the clear height of the seismic support. In addition, the first party responsible for installing seismic brackets will provide a report certified by a third-party authoritative organization before winning the bid. This report includes the load values of seismic supports, which can ensure the correctness and rationality of the installation of seismic supports. We can request Party A to provide a copy for review and use after the installation of the seismic bracket. Generally, before winning the bid, Party A needs to provide a preliminary design plan for the seismic support and a quotation for the project. If winning the bid, Party A needs to provide multiple drawings. For example, the list of materials used for seismic supports, calculation sheets, detailed drawings and location diagrams of seismic support nodes. Generally speaking, on-site installation guidance does not require additional charges. So which local department can conduct acceptance inspection after the installation of seismic brackets? Of course, the local quality inspection station is responsible for the acceptance work. The general acceptance will compare the actual installed seismic support with the design drawing. In addition, many projects will include systems such as fire hydrants, sprinklers, water supply, electrical systems, and smoke and exhaust accident ventilation. Of course, destructive testing may be required in some special projects.

The standardization of seismic brackets has not been implemented for a long time, and some brands commonly used in the market are from regulatory agencies. Therefore, some domestic brands currently have relatively high prices in the market. But this has also attracted many manufacturers who see business opportunities. So, how to choose seismic brackets on the market? Here are a few suggestions. Firstly, understand and verify the basic introduction of the brand. We can request the manufacturer to provide similar past cooperation cases, testing reports, third-party certification materials, etc. Secondly, we can visit the manufacturing factory to confirm the supplier's supply capability and product quality. Among them, the annual output and management of the seismic bracket production factory, as well as the production process of seismic brackets, are the focus of the investigation. Thirdly, we can go to the installation site of the project that has already been handled by the seismic support manufacturer. At the installation site of the seismic bracket, the installation quality of the staff can be monitored and customer feedback on the installation can be received.
