Problems solved by technology

[0004] Due to the late start of my country's prefabricated buildings, basic research is blank in many areas, which cannot provide guidance for engineering practice
Due to the characteristics of assembly, the connection mode and construction characteristics of nodes not only affect the overall mechanical performance of the structure but also affect the production efficiency
At present, my country mainly adopts wet connection, but wet connection affects the construction period and cannot fully utilize the advantages of assembly
Although there are applications for dry connections, the structure is complicated and installation is difficult, and the energy dissipation capacity is seriously insufficient.

Example Embodiment

[0037] In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of the embodiments of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0038] Such as Figure 1-4 As shown, a new type of dry connection energy-consuming beam-column node in the embodiment of the present application includes high-strength bolts 5 for connection and fastening, and a precast concrete corbel column 1 for bearing vertical loads. Rectangular precast concrete notched beam 2, connecting steel plat

Abstract

The invention provides a novel dry process connected energy-consuming beam column joint based on a corbel. The joint comprises a prefabricated concrete corbel column, pre-buried steel plates and connecting steel plates, wherein the corbel section of the prefabricated concrete corbel column is stepped, and a notch section of a prefabricated concrete notch beam is matched with the stepped section ofthe corbel and is in lap joint to the stepped section; the pre-buried steel plates are separately pre-buried on the upper and lower surfaces of the corbel and the prefabricated concrete notch beam, friction plates are arranged outside the pre-buried steel plates, and slight tooth spaces are arranged on the sides, facing the pre-buried steel plates, of the friction plates; and the connecting steelplates are arranged on the left and side sides of the prefabricated concrete notch beam and the corbel lap joint section. The beam column joint overcomes the defect that it still needs to support a framework, cast concrete on site and maintain the concrete in a construction site in a current wet process operation, so that the construction efficiency is improved, a template bracket is reduced andthe economical benefit is improved.
