Beam column integral prefabricated joint with rigid template support at connecting position and construction method of beam column integral prefabricated joint

Abstract

The invention discloses a beam column integral prefabricated joint with a rigid template support at a connecting position and a construction method of the beam column integral prefabricated joint. Thebeam column integral prefabricated joint with the rigid template support at the connecting position comprises a cross beam, a steel template and a prefabricated column with a prefabricated joint, theprefabricated joint extends to form a butt-joint segment in butt joint with the cross beam, the steel template is fixedly connected with the butt-joint segment, the cross beam is connected to the steel template, the steel template, the butt-joint segment and the cross beam are fixedly connected through a casting connecting segment, the butt-joint segment extends to form an inclined connection steel bar and column connection steel bars, the inclined connection steel bar and the column connection steel bars extend into the casting connecting segment, the extending-out end of the inclined connection steel bar is fixedly connected with the steel template, the cross beam extends toward the casting connection segment to form beam connecting steel bars, and the beam connecting steel bars in thecasting connection segment are in overlap joint with the beam connection steel bars. The stress of the casting connection segment is smaller than that of a casting segment of a traditional beam columnjoint.

Description

technical field [0001] The invention relates to the field of construction, in particular to a beam-column integral prefabricated joint with a rigid formwork support at the joint and a construction method thereof. Background technique [0002] The prefabricated building has the advantages of improving project quality, shortening the construction period, simplifying the on-site construction process, reducing construction intensity, improving the site environment, reducing pollution, and reducing wet operations. At the same time, prefabricated buildings can effectively save resources and energy and improve material efficiency. In terms of achieving building energy efficiency and structural performance, reducing the demand for site and environmental conditions for on-site construction, reducing the number of on-site construction labor, reducing construction waste and adverse impacts of construction on the environment, facilitating information management, etc., in line with the re...

AI Technical Summary

Problems solved by technology

[0005] (1) The traditional prefabricated beam-column connection adopts mechanical sleeve grouting connection, which requires precise alignment of the steel bars protruding from the beam end and the protruding steel bars at the column nodes, which is difficult in actual operation and has hidden safety and quality risks;

[0006] (2) The welded connection of steel bars needs to transport the welding machine to the installation layer, and the quality of the weld seam during the welding process is difficult to control;

[0007] (3) The pouring strength of the beam end pouring section using ordinary concrete is low, and the integrity of the concrete frame structure is poor
