Description

Technical Field

[0001] This utility model relates to the field of seismic bracing technology, and in particular to a suspended seismic bracing. Background Technology

[0002] In existing technologies, suspended seismic bracing (also known as portal seismic bracing hangers) is an important seismic support device in building electromechanical systems, achieving lateral and longitudinal seismic protection for pipelines through specific structural design. Structural components: a load-bearing hanger, consisting of two or more vertical hangers, used to bear the gravity load of the pipeline system; horizontal beams and seismic braces, with the horizontal beams connecting the hangers to form a portal frame; the seismic braces are connected by hinges or right angles, achieving horizontal and vertical constraints by decomposing seismic forces; and an accessory system, including C-channel steel, channel steel locks, expansion bolts, high-strength screws, etc., to ensure overall rigidity and connection reliability.

[0003] Chinese patent application number 202322249490.6 discloses a portal-type seismic bracing system. This portal-type seismic bracing system facilitates the adjustment of the length of the vertical columns. However, the vertical columns are equipped with springs, which, although increasing the buffering performance and helping to resist impact, reduces the rigidity of the overall device and causes a certain degree of instability. This is not conducive to improving the support capacity and seismic resistance of the overall device in actual use. Utility Model Content

[0013] As a further improvement of this utility model: a bracket connecting cylinder is fixedly connected to the top of the mounting connector, and a reinforcing support frame is fixedly inserted into the inside of the bracket connecting cylinder.

[0014] As a further improvement of this utility model: the outer wall of the bracket connecting cylinder is fitted with an installation connecting plate, and both ends of the upper surface of the installation connecting plate are fixedly connected with positioning rotating frames.

[0015] As a further improvement of this utility model: a reinforcing inclined arm is rotatably mounted inside the positioning rotating frame, and a sliding inclined arm is fixedly mounted inside the inner cavity of the reinforcing inclined arm.
