Prefabricated concrete anti-seismic joint

Abstract

The invention discloses a prefabricated concrete anti-seismic joint. The prefabricated concrete anti-seismic joint comprises a prefabricated concrete column, a prefabricated concrete beam, an upper connecting steel plate, a lower connecting steel plate, transverse bolts, vertical steel padding plates, vertical bolts and a steel cross shearing-resistant piece, wherein the transverse bolts and the vertical bolts are bolts applying prestressing force, the prefabricated concrete column is provided with a bracket, two rectangular grooves are formed in the end, away from the concrete beam, of the concrete column, and are matched the vertical steel padding plates, first transverse bolt holes are formed in the rectangular grooves respectively and used for transversely running through the concretecolumn, the cross section of the prefabricated concrete beam is in a T shape, second transverse bolt holes matched with the first transverse bolt holes are formed in the end of the concrete beam, andfirst vertical bolt holes are vertically formed in the portions, close to the end, of the concrete beam. The prefabricated concrete anti-seismic joint is easy to assemble, convenient and fast and highin anti-seismic effect.

Description

technical field [0001] The invention relates to a building connection node, in particular to a prefabricated assembled concrete anti-seismic node. Background technique [0002] In the past few decades, the research on structures in our country is mainly reflected in the research on the integrity of the structure and the research on the seismic performance of components, and there are theoretical deficiencies in the joints. In the early 1980s, node research gradually gained the attention of scholars and researchers. Scholars at home and abroad have done a series of research on this. But as far as the current research, especially the domestic research, the main problems and limitations are: first, most of the designs cannot be completely separated from the cast-in-place, and the combination of dry and wet is used, and there is still the situation of on-site welding, which cannot be efficient and quick ; Second, the node design is too complicated, the accessories are cumberso...

Problems solved by technology

But as far as the current research, especially the domestic research, the main problems and limitations are: first, most of the designs cannot be completely separated from the cast-in-place, and the combination of dry and wet is used, and there is still the situation of on-site welding, which cannot be efficient and quick ; Second, the node design is too complicated, the accessories are cumbersome, and it is not easy to replace

At the same time, in the current construction market, most consumers are still not confident about the seismic performance of prefabricated buildings. , the seismic resistance of structural joints is still a problem that must be solved urgently
