A kind of prefabricated plate beam interface vibration damping and shear connection structure

Abstract

The invention provides an assembled plate-girder interface vibration-damping and shear-resisting connection structure, which includes shear-resisting steel bars, the lower part of the shear-resisting steel bars is pre-buried in the assembled beam; For the shear reinforcement, at the periphery of the prefabricated hole, at the bottom of the prefabricated slab near the interface of the slab beam, two additional first tensile bars for preventing concrete splitting are attached, and the shear reinforcement at the top of the prefabricated beam Nearby, a second tensile reinforcement for preventing concrete shearing and cracking is attached; the surface of the reinforcement is wrapped with elastic material; the contact part between the assembled beam top and the assembled plate is provided with a damping plate, and a hollow hollow is arranged in the damping plate. A cylindrical space is reserved in the center of the cylindrical space, and a through hole that penetrates up and down is reserved. The invention has the advantages of simple structure, convenient construction and strong shear bearing capacity, and has good effects on damage and service life caused by the seismic capacity of repeated vibration loads.

Description

Technical field: [0001] The invention relates to the field of prefabricated prefabricated concrete structure buildings, in particular to a connection structure of an assembled slab beam. Background technique [0002] Prefabricated structure is an important construction method for prefabricated buildings. The safe, reliable, convenient and efficient connection between prefabricated parts, slabs, columns, walls and other components directly determines the development of concrete structure assembly technology. It is one of the important directions for the development of building structures in my country. It is conducive to the development of building industrialization in China, improving production efficiency, saving energy, developing green and environmentally friendly buildings, and improving and ensuring the quality of construction projects. [0003] The connection methods of prefabricated concrete joints mainly include the following. One is the sleeve grouting connection tec...

Problems solved by technology

In the prior art, especially the anti-seismic capacity of the plate-girder joints subjected to repeated vibration loads, and the durability of the anti-seismic structure have not been involved; in addition, if the vibration-absorbing structure is added, it is often necessary to increase the steel structure to complete, the process is complicated, and the cost higher
