Anti-seismic bracket with bump damping adjusting function

Abstract

The invention discloses an anti-seismic bracket with the bump damping adjusting function. The anti-seismic bracket comprises a supporting cross beam, traction end parts and traction parts; an ejectorrod assembly is upwards connected to each traction end part at the two ends of the supporting cross beam along the dead center; the upper ends of the ejector rod assemblies are connected to a ceiling;the traction end parts are supported by utilizing the ejector rod assemblies; the traction parts are hinged to the symmetric positions of the left sides and the right sides of the ejector rod assemblies and the positions right behind the ejector rod assemblies; and the upper ends of the traction parts are fixed to the ceiling through hinge bases. According to the anti-seismic bracket, the bump damping adjusting function is achieved, in addition, after thrust is applied to the centers of the traction end parts at the two ends of the supporting cross beam and balance tensile force is simultaneously applied on the periphery of the thrust, prestress thrust can be added to the ejector rod assembly providing the thrust by utilizing the interaction between the thrust and the tensile force, pre-stress tensile force is provided for the traction parts providing the tensile force, so that the traction end parts at the two ends of the supporting cross beam can be in a stress state, the stabilityof the supporting cross beam can be well improved, and therefore the stability of a pipeline component is improved.

Description

technical field [0001] The invention belongs to the technical field of pipeline anti-seismic auxiliary supports, and in particular relates to an adjustable anti-seismic support with shock-absorbing and damping effects. Background technique [0002] Existing components such as cable ducts or air ducts used on the top of buildings are made by inserting expansion wire sleeves on the roof (ceiling) and connecting the expansion wires as hanging parts. The connection strength is very weak. When an earthquake occurs, the building will swing. , the pipes installed on the top of the building will also swing along with the cables and other components. This component swing will not be eliminated by itself, and the swing amplitude of the components will gradually increase with the swing of the building, and may even resonate with the swing of the building , Repeated high-intensity swing action will cause damage to the fixed parts of the pipeline components, and then cause damage to the ...
