Description

Connecting structure capable of replacing coupling beam damper

Technical Field

Energy dissipation and shock absorption of a building structure mean that a proper energy dissipation part is arranged in the building structure, and the energy dissipation part can be composed of an energy dissipation and shock absorption support, a steel plate damper, a viscous damper and the like and a supporting member.

The connecting beam is widely applied to shear wall structures and frame-tube structure systems and is used as a first anti-seismic defense line for energy consumption. The traditional reinforced concrete coupling beam has the defects of low ductility, difficult repair after damage and the like, the engineering industry proposes that the coupling beam damper is adopted to replace the traditional coupling beam for centralized energy consumption, and the coupling beam damper can realize replacement after earthquake through bolt connection so as to improve the earthquake-resistant toughness of the building. In addition, the arrangement of the coupling beam damper has little influence on the building function, and has wide application prospect in the field of earthquake-resistant energy dissipation of buildings.

In the prior art, the connecting beam damper is generally replaceable by adopting bolt connection, but bending resistance and shearing resistance of a connecting surface are only realized by adopting bolt connection, the requirement of general bolts is large, and meanwhile, experiments show that the slippage of the bolts is also large, so that the energy consumption effect of the connecting beam damper is influenced. On the basis, the patent document discloses a connecting structure of a replaceable coupling beam and a building (CN 206448394U) containing the connecting structure, wherein the connecting structure adopts a groove and a bulge for shearing resistance so as to reduce the slippage of a bolt under the action of an earthquake, and the same construction method is also adopted in the 'replaceable steel coupling beam anti-seismic performance test research' (the test research on the anti-seismic performance of replaceable steel coupling beam [ J ] of architecture structure academic newspaper, 2015,36(10):1-10 ]), but the technical scheme has the following defects: (1) the processing of the convex part is complex, and more steel needs to be cut off on a thick steel plate; (2) due to the existence of the bulge part, the installation can be realized only by adopting lateral insertion, and when the equipment pipeline is arranged laterally, the equipment pipeline is required to be firstly dismantled for installation; (3) when the residual deformation after the earthquake exceeds a certain range, the connecting beam damper can be replaced extremely complexly. Therefore, the replaceable coupling beam damper which is simple to machine and manufacture, convenient to disassemble and assemble and clear in stress has important significance in popularization of coupling beam energy dissipation and shock absorption.
