Beam-column connection structure based on combination of anti-seismic embedded steel plate and steel module

Abstract

The invention discloses a beam-column connection structure based on combination of an anti-seismic embedded steel plate and a steel module. The beam-column connection structure comprises a prefabricated concrete column, a prefabricated concrete beam, a bending-resistant steel plate and a shearing-resistant steel plate. A concrete column steel module is arranged at one side of the prefabricated concrete column; a steel module groove matching the concrete column steel module is arranged at one end, facing the prefabricated concrete column, of the prefabricated concrete beam; the bending-resistant steel plate is arranged horizontally in the concrete column steel module; and one end of the bending-resistant steel plate extends into the prefabricated concrete column and the other end of the bending-resistant steel plate extends out of the concrete column steel module. A first groove perpendicular to the bending-resistant steel plate is formed in the concrete column steel module above the bending-resistant steel plate. According to the invention, standardized production of all components is realized while the high connection reliability of the prefabricated concrete column and the prefabricated concrete beam. The construction cost is low and the construction efficiency is high.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to an anti-seismic pre-embedded steel plate and concealed corbel matching type beam-column connection structure. Background technique [0002] The prefabricated concrete structure means that each component is processed according to the standard size in the prefabricated factory, and transported to the site for direct splicing and lapping to form the building structure. Prefabricated buildings can overcome the shortcomings of traditional concrete structure construction methods such as inconsistent construction standards, long construction period, susceptibility to site environment, serious pollution, and high cost, and can greatly improve the safety and seismic performance of prefabricated structures. Therefore, in Public buildings, long-span structures, high-rise and super high-rise buildings all over the world have a wide range of applications. [0003] Whether the pre...

Problems solved by technology

Judging from the current domestic research, the main problems and limitations are that most of the designs cannot be completely separated from cast-in-place, the design of the precast concrete connection structure is complicated, the accessories are cumbersome, and it is not easy to replace; most of them involve the use of exposed corbels, which are safe under stress Reliable but not aesthetically pleasing, dark corbels are beautiful in appearance, more suitable for commercial buildings or residential areas, but not used effectively
