Problems solved by technology

[0003] 1) The joint damage of the dry-connected beam-column joints is mainly concentrated on the angle steel. With the large residual deformation of the angle steel, the occurrence of cracks in the beam-column joints will be aggravated;
[0004] 2) When an earthquake occurs, the existing beam-column joints mainly rely on the prestressed tendons to bear the shear force and resist the bending moment, which will cause different degrees of prestres

Abstract

The invention relates to a prestress self-resetting reinforced concrete dry type connecting beam-column joint. The joint comprises a reinforced concrete column, a reinforced concrete beam, a hidden bracket, a prestress rib, an anchorage device, angle steel, a bolt and an embedded bolt sleeve. The prestress self-resetting reinforced concrete dry type connecting beam-column joint has the beneficialeffects that the joint has the remarkable advantages of energy conservation, environmental protection, high field construction efficiency and the like, the shear capacity and residual deformation resistance of a reinforced concrete structure can be effectively improved, the joint has good self-resetting capacity after an earthquake, and the purposes of structural shock insulation and effective prolonging of the service life of a building are achieved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a prestressed self-resetting reinforced concrete dry connection beam-column node. Background technique [0002] In recent years, with the rapid development of my country's science and technology and economy, the industrialization of construction has gradually become an inevitable trend in the development of my country's construction industry. At the same time, the increasingly serious shortage of labor in the construction industry and the environmental problems of construction sites have attracted more and more attention from the community, which has further accelerated the development process of construction industrialization. The research on prefabricated building systems is one of the important links in promoting the research of construction industrialization, and the dry connection of beams and columns of prefabricated concrete structures is the most important p...
