Typified form support method for expansion joint between residence apartments

Abstract

The invention discloses a typified form support method for an expansion joint between residence apartments. The method comprises the following steps that a plurality of expansion joint inner and outerform clamping devices are acquired, then two inner forms located at the expansion joint and two outer forms on the outer sides of the inner forms are erected, the outer side of the outer form on oneside is provided with the expansion joint inner and outer form clamping devices in a vertically and horizontally interval arrangement mode, and the expansion joint inner and outer form clamping devices can clamp the inner forms and the outer forms on the two sides. According to the method, the construction difficulty is reduced, meanwhile, the form support is stable, and the concrete pouring quality is improved.

Description

technical field [0001] The invention relates to the field of concrete construction, in particular to a formwork support method for expansion joints between residential unit buildings. Background technique [0002] The traditional formwork method for the expansion joints between residential units is mostly to fill the expansion joints with polystyrene boards to separate the formwork or to set up the formwork twice. The method of filling polystyrene boards often leads to instability of the formwork system, and because polystyrene boards are filled at the expansion joints, which are flexible materials, it is easy to cause the formwork to shift during the concrete pouring process, resulting in problems of poor verticality and flatness . What's more, there will be quality problems of mold explosion, resulting in waste of concrete, and a lot of manual processing is required, which is wasteful and laborious. At the same time, it is very troublesome to remove the formwork at the e...

AI Technical Summary

Problems solved by technology

The method of filling polystyrene boards often leads to instability of the formwork system, and because expansion joints are filled with polystyrene boards, which are flexible materials, it is easy to cause the formwork to shift during the concrete pouring process, resulting in problems of poor verticality and flatness

What's more, there will be quality problems of mold explosion, which will cause waste of concrete and require a lot of manual processing, which is wasteful and laborious

At the same time, it is very troublesome to remove the formwork at the expansion joint in the traditional method, which will cause great damage to the formwork and cause a lot of loss of the formwork

However, the method of pouring the formwork twice will cause a waste of construction period, and at the same time, there will be quality problems of poor verticality and flatness of the wall during the second formwork pouring
