Fabricated building frame hollow column joint structure and construction method thereof

Abstract

The invention relates to a fabricated building frame hollow column joint structure. The fabricated building frame hollow column joint structure comprises lower-layer prefabricated stand columns, connecting column bodies inserted into the upper portions of the lower-layer prefabricated stand columns, upper-layer prefabricated stand columns arranged on the upper portions of the connecting column bodies in a sleeving mode and cross beams with the ends installed on the lower side walls of the upper-layer prefabricated stand columns and the upper side walls of the lower-layer prefabricated stand columns; mounting cavities are formed in the upper end faces of the upper-layer prefabricated stand columns and the lower end faces of the lower-layer prefabricated stand columns in the vertical direction, dovetail grooves extending in the horizontal direction are formed in the outer side walls, located in the mounting cavities, of the upper-layer prefabricated stand columns and the outer side walls, located in the mounting cavities, of the lower-layer prefabricated stand columns, mounting plates are fixedly connected to the ends of the cross beams, dovetail blocks embedded in the dovetail grooves in a sliding mode are arranged on the side wall of the mounting plates in a protruding mode, and the mounting cavities are provided with limiting mechanisms for limiting the sliding positions of the dovetail blocks. The fabricated building frame hollow column joint structure has the effect of facilitating installation of the beam column joint.

Description

technical field [0001] The present application relates to the field of prefabricated concrete frames, in particular to a hollow column joint structure of prefabricated building frames and a construction method thereof. Background technique [0002] With the country's vigorous promotion of industrialized buildings, technologies related to prefabricated buildings have developed rapidly. While studying the performance of prefabricated buildings, the research on structural components of prefabricated buildings is also changing with each passing day, among which there are many studies on the form of prefabricated components. [0003] Beam-column joints are the connection center of column modules and beam modules, and its construction measures are one of the main issues in frame structure design. Traditionally, when assembling the column modules and the beams installed and connected to the column modules, it is usually necessary to weld and fix the steel bars reserved for the bui...

AI Technical Summary

Problems solved by technology

Traditionally, when assembling the column modules and the beams installed and connected to the column modules, it is usually necessary to weld and fix the steel bars reserved for the building modules. The welding time is long and the assembly is troublesome. Alignment assembly is more difficult, and some measuring tools need to be combined with repeated inspections, and the installation efficiency is low
