The types of seismic supports mainly include the following:
Lateral seismic support hanger: This type of support hanger is installed on the same side of the pipeline and is mainly used to resist the left and right swing of the pipeline. Its design principle is to provide lateral resistance through slant support parallel to the cross section of the pipeline, which is usually used for shear wall, frame, inter story shear connection and other structures.
Longitudinal seismic supports and hangers: There are lateral seismic supports and hangers that are mainly used to resist the forward and backward swinging of pipelines. Longitudinal seismic supports and hangers are installed in the vertical parts of buildings, such as columns or walls, to provide vertical stiffness and stability.
Single pipe support: It is composed of a load-bearing hanger and an anti-seismic slant support, and is suitable for scenes requiring simple support.
Door type seismic support and hanger: It is composed of two or more load-bearing hangers, beams and seismic slant support, and is suitable for scenes requiring greater support.
Comprehensive seismic support hanger: suitable for complex pipeline systems, providing comprehensive seismic support.
Rectangular duct seismic support hanger: specifically designed for seismic support of rectangular ducts.
The purpose and installation requirements of seismic supports:
Seismic supports are mainly used to limit the displacement of ancillary mechanical and electrical engineering facilities, control facility vibration, and transfer loads to the load-bearing structure. In earthquakes, seismic supports can significantly reduce damage to facilities, minimize economic losses and casualties. During installation, it is necessary to select the appropriate type of support and hanger based on the diameter and weight of the pipeline, and ensure that all connecting components achieve rigid fit with the channel steel, without displacement and precise positioning.
