Assembled reinforced concrete framework structure beam-column joint and manufacturing method thereof

Abstract

The invention relates to an assembled reinforced concrete framework structure beam-column joint and a manufacturing method thereof, and belongs to the technical field of building materials and building construction. The assembled reinforced concrete framework structure beam-column joint is composed of a splicing joint (13) of a prefabricated framework column (11) and a prefabricated framework beam (12), and cast-in-place concrete (14). Column longitudinal ribs (131) in the prefabricated framework column (11) extend out of the top of the column to form column top reserved longitudinal ribs (1311). A plurality of joint column hoops (132) are arranged around the column top reserved longitudinal ribs (1311) and bound to the column top reserved longitudinal ribs (1311). The prefabricated framework beam (12) is spliced to the top of the prefabricated framework column (11). A beam bottom longitudinal rib (133) in the prefabricated framework beam (12) extends out towards the splicing head of the prefabricated framework beam (12), and penetrates through the splicing joint (13) to be linearly anchored. According to the assembled reinforced concrete framework structure beam-column joint and the manufacturing method thereof, the design of connection of a framework joint and a framework beam column around the framework joint is modified, linear anchoring of the framework beam bottom longitudinal rib and continuous through anchoring of a framework beam top longitudinal rib are achieved, connection integrity of an assembled reinforced concrete framework structure is enhanced, and the assembled reinforced concrete framework structure can possess better earthquake-resistant ductility.

Description

technical field [0001] The invention belongs to the technical field of building materials and building construction, and relates to an assembled reinforced concrete frame structure beam-column node and a manufacturing method thereof. Background technique [0002] Prefabricated concrete structures refer to concrete structures assembled by prefabricated concrete components through reliable connection methods, including assembled integral concrete structures, fully assembled concrete structures, etc. In construction engineering, it is referred to as prefabricated building; in structural engineering, it is referred to as prefabricated structure. Prefabricated components refer to concrete components prefabricated in factories or on site, such as beams, slabs, walls, columns, balconies, stairs, canopies, etc. [0003] Traditional building construction technology has low production efficiency, slow construction speed, long construction period, high material consumption and high la...

Problems solved by technology

[0014] The purpose of the present invention is to overcome the deficiencies of the prior art, aiming at the longitudinal bars of the frame beams at the joints of prefabricated reinforced concrete frame beams and columns that are not anchored in a straight line into the frame columns until the frame beams of the adjacent spans, the longitudinal bars of the frame beams are anchored In order to solve the problem of poor stability, improve the design of the connection between the frame nodes and the surrounding frame beams and columns, realize the linear anchorage of the longitudinal reinforcement at the bottom of the frame beam and the continuous penetration anchorage of the longitudinal reinforcement at the top of the frame beam, and strengthen the connection of the prefabricated reinforced concrete frame structure The integrity of the structure makes it have better seismic ductility, and at the same time solves the problem of the fabrication method of the beam-column joints of the fabricated reinforced concrete frame structure
