I-shaped energy dissipation connecting part for coupled shear wall structure

Abstract

The invention provides an I-shaped energy dissipation connecting part for a coupled shear wall structure and belongs to the technical field of prefabricated concrete component structures. The I-shapedenergy dissipation connecting part comprises a T-shaped connecting piece I, a T-shaped connecting piece II, friction plates and friction type high-strength bolts. T-shaped structural parts are arranged between shear wall columns and a connecting beam, the friction plates and the friction type high-strength bolts are arranged between the structural parts, and the friction energy dissipation function is realized. The I-shaped energy dissipation connecting part has good energy dissipation capacity, has sufficient strength and rigidity and high energy dissipation efficiency and can have a function of protecting a main structure by dissipating earthquake energy when the main structure is under the action of an earthquake, besides, the connecting beam can be timely repaired and replaced when damaged, and the cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of prefabricated concrete component structures, and in particular relates to an I-shaped energy-dissipating connector for combined-limb shear wall structures. Background technique [0002] Prefabricated concrete buildings refer to prefabricated concrete components produced in factories. Concrete structure housing buildings designed and constructed through on-site assembly. The assembly methods of components generally include on-site post-casting laminated layer concrete, steel bar anchoring and post-casting concrete connection, etc. The steel bar connection can be connected by sleeve grouting connection, welding, mechanical connection and lap connection of reserved holes. In the 1980s, prefabricated prefabricated large-slab houses, which were popular in my country, had many hidden dangers and defects that affected structural safety and normal use due to poor structural integrity, leakage, and floor cracks, ...

Problems solved by technology

[0004] In order to solve the above-mentioned existing technical problems, the present invention provides an I-shaped energy-dissipating connector for a combined shear wall structure, mainly for the purpose of developing an engineering energy-dissipating connector with a simple structure and high energy consumption efficiency. The shear wall branches and connecting beams are provided with T-shaped structural parts, and the structural parts are provided with friction plates and friction-type high-strength bolts to play the role of frictional energy dissipation. The present invention not only has excellent energy dissipation capacity, but also has sufficient Strength and rigidity, when the main structure is affected by earthquakes, it can play the role of consuming seismic energy and protecting the main structure. At the same time, when the connecting beam is damaged, it can be repaired and replaced in time, which reduces the cost and can effectively avoid the collapse of buildings caused by earthquakes. Excessive earthquake response leads to high subsequent maintenance costs
