Construction method for joint of fabricated prefabricated wall and cast-in-place structure

Abstract

The invention relates to a construction method for a joint part of an assembly type prefabricated wall body and a cast-in-place structure. Comprising the following steps: deepening rabbets of prefabricated parts; prefabricated parts are installed, wherein an outer wallboard is hung firstly, and then an inner wallboard is hung; a modular hoisting beam is adopted for hoisting the wallboards; the prefabricated wall panel is quickly positioned, and when the prefabricated wall body is hoisted in place, quick positioning measure parts are used for quickly positioning; mounting a prefabricated wallboard inclined support; after the wallboards are rapidly in place, the wallboards are accurately adjusted; a formwork is manufactured and installed; pouring concrete; performing decoration construction; checking and accepting to ensure the perpendicularity of the wall body; the perpendicularity is required not to exceed 3mm. According to the construction method provided by the invention, the integrity of the prefabricated wall and the cast-in-place structure is guaranteed through methods of deepening the rabbets, guaranteeing the perpendicularity of the vertical components, smearing the elastic materials and the like, and the good effects of beforehand prevention and afterwards remedy of cracks of the prefabricated wall and the cast-in-place section can be achieved.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a construction method for the junction of an assembled prefabricated wall and a cast-in-place structure. Background technique [0002] During the construction of the junction between the prefabricated prefabricated wall and the cast-in-place structure, due to the deviation of the verticality of the tongue and vertical components, cracks are prone to appear. Once a crack occurs, high maintenance costs will be required in the remedial process. At the same time, it will also reduce the quality and aesthetics of the entire prefabricated building. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defects, and propose a construction method for controlling cracks at the interface between an assembled prefabricated wall and a cast-in-place structure, which can prevent cracks at the interface during the construction process...
