Construction method for after-pouring band beam-slab template

Abstract

The invention relates to a construction method of a post-pouring strip beam slab template, and is characterized in that the invention comprises the following procedures in sequence: the axial line is rechecked, the beam slab template support is erected, the template of 800 mm-1000 mm width is erected on the both sides of the post-pouring strip, and the reinforcing bar is arranged, the template support becomes an independent system, a concrete beam slab is poured and cured, firstly, the template is removed after the strength of the pouring concrete beam slab reaches the requirement of the template removal, the template on the both sides of the post-pouring strip and the support are not removed, the roughening in the construction joint is cleaned and wetted, the post-pouring strip template is arranged, the epithelium elevation and the smoothness of the pouring strip template after being checked are fixed with the adjacent template at both sides. The invention ensures the wholeness of a post-pouring strip beam slab structure on the both sides, the performance quality of the concrete cast-in-situ at a concrete joint is effectively ensured, in particular to the clean water concrete. Because the method of the invention can not repeatedly remove the post-pouring strip template support system, the mass labor force is saved during the construction, and the construction speed is accelerated, as well as the engineering cost is reduced.

Description

technical field [0001] The invention belongs to a construction method of a building formwork, in particular to a construction method of a post-cast beam plate formwork in a cast-in-place reinforced concrete structure. Background technique [0002] At present, in construction engineering, in order to meet the functional needs and solve the settlement difference between the main body and the podium, the shrinkage and deformation of reinforced concrete, and the temperature stress of concrete, the post-pouring belt method has been widely used in construction engineering. [0003] The traditional construction process of the post-cast beam slab formwork is the same as that of the ordinary beam slab formwork, that is, the top support is used for reinforcement. During construction, the entire beam slab formwork (including the position of the post-pouring belt) is supported as a whole, and then the concrete beam slab is poured and maintained. After the strength of the poured concrete...

AI Technical Summary

Problems solved by technology

The support of the beam-slab formwork on both sides of the post-casting belt is not coherent and not timely. During the concrete pouring process of the post-casting belt, there will inevitably be micro-settlement deformation in the roof frame system. It is difficult to achieve a smooth integration of the old and new concrete joints. The phenomenon of grout leakage and wrong platform often occurs, which not only affects the structural quality of the post-cast concrete, but also causes unsatisfactory appearance
