Cast-in-place area outside moved form-erecting-free fabrication integral joint and construction method thereof

Abstract

The invention discloses a cast-in-place area outside moved form-erecting-free fabrication integral joint and a construction method thereof. The cast-in-place area outside moved form-erecting-free fabrication integral joint comprises a prefabricated column member and a prefabricated beam member. A joint area of the prefabricated column member penetrates up and down and externally extended horizontal longitudinal steel bars are arranged at the joint area, a prefabricated groove is formed in the end part of the prefabricated beam member, the prefabricated groove is formed by enclosing side plateson two sides of a beam and a bottom plate, horizontal longitudinal steel bars extending from the beam end is arranged in the prefabricated groove, the prefabricated groove is a cast-in-place area, concrete is poured in the prefabricated groove, fabrication connection of the prefabricated column member and the prefabricated beam member is realized, and the cast-in-place area is located outside thejoint area of the prefabricated column member. According to the cast-in-place area outside moved form-erecting-free fabrication integral joint, through beam and column prefabrication, concrete precast of the joint area is achieved, the pouring quality of the members and joint concrete is guaranteed, the longitudinal steel bars of the beam and the joint area are in overlap joint and anchored outside the joint area, outside moving of a beam end plastic hinge can be realized, and realization of an aseismic design concept of string column and weak beam, strong shear capacity and weak bending capacity and strong joint and weak member is facilitated.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a formwork-free assembly integral node for moving outside the cast-in-place area and a construction method thereof. Background technique [0002] As a structural form in line with industrial production, precast concrete structure has superior economic, environmental, social benefits and good structural performance, and has been widely used in developed countries and regions such as Europe, America, and Japan. my country's construction industrialization level is relatively low, and the prefabricated assembly technology is backward. It is necessary to innovate and conduct in-depth research on the precast concrete structure system and assembly technology to promote the application and development of precast concrete structures in my country. [0003] In the prior art, the prefabricated concrete structure is mainly an assembled monolithic concrete structure that imitates the mec...

AI Technical Summary

Problems solved by technology

[0005] Assembling the monolithic concrete structure needs to set up formwork in the joint area, and there are many steel bars in the joint area. The concrete is not easy to vibrate and compact, which affects the quality of concrete pouring in the joint area. At the same time, it is necessary to set up supports under the beams, which increases the construction difficulty and cost of the assembled concrete structure.
