Description

Technical Field

[0001] The utility model relates to the technical field of earthquake-resistant brackets, and more specifically to the technical field of a bidirectional earthquake-resistant bracket for a single pipeline. Background Art

[0002] In electromechanical engineering, brackets are often used to fix pipes. However, if a single pipe is directly designed as a bracket according to conventional ideas, the cost of electromechanical installation will increase and the economy will be not strong, especially in projects with strict control of construction costs. When brackets are not used but pipes are installed using pipe bundles, in order to improve the safety and firmness of the pipes, the vertical hangers need to be encrypted. Existing patents disclose the following technologies:

According to the present invention, the adjustment of the rise or fall of the connecting rod is more labor-saving and convenient, and the overall construction and installation balance of the bearing plate and the pipeline is also facilitated.

[0004] The patent with the publication number CN111244858A and the patent name "A Cable Seismic Bracket" discloses the following content: A cable seismic bracket, including a ceiling and a cable, a connecting piece is fixed to the lower surface of the ceiling by screws, a reinforcing frame is fixed to the bottom end of the connecting piece by bolts, a fixing pile is welded to the bottom end of the reinforcing frame, connecting piles are arranged on both sides of the bottom end of the fixing pile, and the connecting piles are hinged to the fixing piles, a connecting frame is welded to the other end of the connecting pile, a wiring box is arranged on the upper surface of the connecting frame, a protective cover is arranged on the upper surface of the wiring box, a seismic bracket is arranged on the inner side of the wiring box, connecting mechanisms are arranged on both sides of the seismic bracket, a through slot is penetrated and opened on the inner wall of the seismic bracket, a seismic mechanism is arranged on the inner side of the through slot, a cable is arranged on the surface of the seismic mechanism, springs are arranged on both sides of the seismic mechanism, and a sleeve is arranged on the outer surface of the spring. The present invention has a cable vibration storage space, increases the tensile strength of the bracket, and improves the seismic performance.

[0005] The existing technology and the above-mentioned patents disclose seismic brackets, which have excessive rigidity due to the large spacing between vertical hangers. When an earthquake wave occurs, key nodes such as the pipe bundle support are damaged first, causing the bracket to fall off and the pipeline to collapse, thus affecting the normal use of the pipeline, which has become an urgent problem to be solved.
