Fabricated concrete structure beam-column dry-wet combination connection structure and implementation method

Abstract

The invention discloses a fabricated concrete structure beam-column dry-wet combination connection structure and an implementation method, and belongs to the technical field of fabricated buildings. Acylindrical cavity structure is arranged at the intersection of a transverse beam and a longitudinal beam, the cylindrical cavity structure comprises an outer cylinder and an inner cylinder, and a square ring-shaped cavity is formed by enclosing the outer cylinder and the inner cylinder; column corner part longitudinal reinforcement bars I and column corner part longitudinal reinforcement bars IIare arranged at four corners of the square ring-shaped cavity, transverse beam longitudinal reinforcement bars and longitudinal beam longitudinal reinforcement bars in the transverse beam and the longitudinal beam penetrate through the outer cylinder and the inner cylinder in sequence; and anchoring heads are connected to the inner ends of the transverse beam longitudinal reinforcement bars and the longitudinal beam longitudinal reinforcement bars. According to the fabricated concrete structure beam-column dry-wet combination connection structure and the implementation method, a modular beam-column joint core area connection structure is formed through the construction method of the inner cylinder and outer cylinders, the problems of multi-directional reinforcement bar anchoring connection of a beam body, complex intersection anchoring connection of column body longitudinal reinforcement bars of and stirrups crossing and installation are solved, the process link and construction costof a formwork and a support are saved, and the fabricated concrete structure beam-column dry-wet combination connection structure has the advantages and characteristics of modularization, integration,integration and informatization.

Description

technical field [0001] The invention relates to the technical field of prefabricated buildings, in particular to a dry-wet combined connection structure and implementation method of prefabricated concrete structure beams and columns. Background technique [0002] Prefabricated buildings are industrialized buildings assembled by building structural components, building components and parts, electromechanical equipment, etc. through reliable connections, including prefabricated concrete structures, steel structures, wood structures, and hybrid structures. Prefabricated concrete buildings are one of the main forms of prefabricated buildings in my country, an important part of new industrialization, and an important way to realize the modernization of the construction industry. The use of prefabricated buildings is conducive to improving the quality, efficiency and benefits of construction projects, improving the working environment and saving labor; it is conducive to promoting...

AI Technical Summary

Problems solved by technology

[0007] One is the location conflict of steel bars, the number of steel bars is large, the location is dense, the length of steel bar anchorage in the joint area is large or the anchorage is bent, especially the longitudinal steel bars in the four directions of the vertical and horizontal beams are difficult to avoid in the prefabricated installation of the joint core area;

[0008] The second is that it is inconvenient to lift and install during construction, and it is difficult to lift in place due to the location and installation of steel bars;

[0009] The third is that the shape of the joint area is complex, and the longitudinal reinforcement of the column, the stirrup, the vertical and horizontal reinforcement of the beam body, etc. intersect, and there are problems such as supporting formwork, pouring concrete, supporting and frame erection in wet construction.

The problems existing in wet construction are not conducive to the development and promotion of industrialization, informatization, and modular construction of prefabricated concrete structures
