Abstract

The invention relates to a fabricated frame structure column-column bundled rebar connecting structure. The fabricated frame structure column-column bundled rebar connecting structure comprises a prefabricated concrete column and a bundled rebar. The bundled rebar is anchored on the prefabricated concrete column, an inwards-recessed cavity structure is arranged in the prefabricated concrete column, and the bundled rebar anchored on the prefabricated concrete column is mounted in the inwards-recessed cavity structure. An anchor socket for mounting the bundled rebar is arranged at the upper endof the prefabricated concrete column, and a middle round hole and peripheral threaded holes are formed in the anchor socket. The bundled rebar comprises an edge longitudinal bar on the upper portion,anchoring longitudinal bars on the lower portion and an anchoring seat in the middle. The lower portion of the edge longitudinal rebar is anchored in the prefabricated concrete column. A grouting holecommunicating with the inwards-recessed cavity structure is formed in the lower portion of the prefabricated concrete column, and a grout discharge hole communicating with the inwards-recessed cavitystructure is formed in the upper portion of the prefabricated concrete column. As for the problems that prefabricated component rebars in a fabricated building are abundantly and densely configured,the number of connector is large, and the mounting efficiency is low, based on an efficient rebar configuration design concept, the hoisting weight is reduced, and rapid and effective assembly is achieved.

Description

technical field [0001] The invention relates to the technical field of prefabricated buildings, in particular to a post-column bundled steel bar connection structure of a prefabricated frame structure. Background technique [0002] Prefabricated buildings are buildings assembled from prefabricated parts and components on site, which have the advantages of improving building quality, improving efficiency, saving materials, saving labor and improving working conditions. According to different connection methods, it can be divided into "assembled monolithic concrete structure" and "fully assembled concrete structure". [0003] The PC components of the fully assembled concrete structure are formed into a whole by dry connection (such as bolt connection, welding, etc.). Assembled integral concrete structure refers to a structure that is connected by prefabricated concrete components in a reliable way and then poured concrete and cement-based grouting material on site to form an ...
