Description

Technical Field

[0001] The utility model relates to the technical field of seismic equipment, in particular to a novel support hanger. Background Art

[0002] In the field of construction engineering, the laying of cable trays is a crucial link. In order to reduce the damage caused by earthquakes and other vibrations to cable trays, it is particularly important to install seismic support hangers. Such support hangers can efficiently control the vibration of cable trays during earthquakes, ensuring that the load is safely transmitted to the building structure. During an earthquake or vibration, the seismic support hanger can provide the necessary stability for the cable tray and resist the vibration impact from different directions. All components of the seismic support hanger should be designed as prefabricated parts for easy and quick installation and operation.

[0003] Currently, traditional seismic support hangers mostly use angle steel connectors to connect the cable tray and the support hanger. One end of the angle steel is fixedly connected to the cable tray through a bolt in a penetrating manner, and the other end is fixed to the seismic support hanger. This connection method requires prefabricating penetrating holes on the side of the cable tray, which often has a large error in the actual installation process and needs to be adjusted, which not only affects the installation efficiency but also increases the workload. In addition, since the angle steel connector is fixedly connected by bolts, which is a rigid connection method, during vibration, this connection method not only lacks shock absorption protection for the cable tray, but also the bolt connection may become loose due to vibration, which poses a threat to the stability of the entire structure. Therefore, improving the design and connection method of the seismic support hanger to enhance its seismic performance and installation efficiency is an urgent problem to be solved currently.
