Multidimensional composite tensile-bearing-type anti-seismic joint device

Abstract

The invention belongs to the technical field of anti-seismic safety and particularly relates to a multidimensional composite tensile-bearing-type anti-seismic joint device. The multidimensional composite tensile-bearing-type anti-seismic joint device is constituted by a special-shaped steel base, an anchoring component, a spherical cage universal coupling, damping and energy-consumption tensile-bearing rods, a bolt, an aluminum alloy cover plate, a rubber damping pad and rubber strips. The anchoring component and a concrete beam are poured together, so that the special-shaped steel base and the concrete beam are connected into a whole; one end of the aluminum alloy cover plate is connected with the special-shaped steel base through screws, and gaps between the aluminum alloy cover plate and the special-shaped steel base are filled with the rubber strips. The special-shaped steel base and a net-shaped composite damping and energy-consumption unit are connected through the spherical cageuniversal coupling, and the composite damping and energy-consumption unit is constituted by a large quadrilateral structure constituted by the damping and energy-consumption tensile-bearing rods, andthe rubber damping pad arranged in a quadrangle in a filled mode. Multidimensional change of anti-seismic joint deformation can be achieved in the vibrating direction, the material property is sufficiently utilized, the anti-seismic and damping efficiency is improved, and the good composite damping effect is achieved.

Description

Technical field [0001] The invention belongs to the technical field of seismic safety, and particularly relates to a seismic joint anti-seismic device of a building structure, which is suitable for multi-dimensional damping and energy consumption of seismic joints of a building structure and improves the seismic safety of the building structure. Background technique [0002] The responsibility for the safety of building structures is heavy, ranging from economic losses to human life. Therefore, in the process of structural construction, safety design and construction quality are the guarantee for the safety of the building structure, and the seismic resistance of the building structure is the basis of safety design. [0003] In the prior art, traditional devices can provide displacements in both longitudinal and vertical directions for seismic joints used on floors and exterior walls. The displacement between seismic joints caused by seismic vibrations is in any direction. Tradition...

Problems solved by technology

[0005] The technical problems in the prior art that the present invention solves are the multi-dimensionality of the movement between the building's anti-seismic joints caused by the arbitrariness of the seismic wave, the energy of the seismic wave is huge, but the energy consumption efficiency of the anti-seismic joint device is low, and the structures on both sides of the anti-seismic joint can resist overturning during an earthquake Aiming at the above-mentioned existing technical problems, a multi-dimensional composite tie-able anti-seismic joint device was designed.
