Construction method for reducing thickness of aluminum formwork wall

Abstract

The invention discloses a construction method for reducing a thickness of an aluminum formwork wall. The construction method comprises the following steps that an aluminum alloy section inlay strip equivalent to the wall unilateral thinning amount is designed according to a constructed building wall thickness modulus; the aluminum alloy section inlay strip is processed; the aluminum alloy sectioninlay strip is fixedly connected with an internal corner formwork through a connecting pressing plate; and the internal corner formwork connected with the aluminum alloy section inlay strip is correspondingly connected with a wall formwork and a floor formwork. According to the construction method, an original wall formwork, the floor formwork or the internal corner formwork is not needed to be replaced, so that the general rate of a standard formwork is high, and the production efficiency and the processing efficiency are improved; and meanwhile, a method the same as an installation method ofan existing formwork is adopted, the internal corner formwork connected with the aluminum alloy section inlay strip is correspondingly connected with the wall formwork and the floor formwork for mounting, a corner formwork at a three-internal-corner junction is replaced, the influence of replacing of the formwork on the construction progress is avoided, the construction efficiency is improved, the operating difficulty is reduced, and the labor cost is reduced.

Description

technical field [0001] The invention relates to the field of building formwork, in particular to a construction method for reducing the thickness of an aluminum formwork wall. Background technique [0002] With the rapid development of urbanization, low-rise buildings are transformed into high-rise buildings to increase the building use area and reduce the land occupation area. The load-bearing walls of the building are usually aluminum formwork walls, and the aluminum formwork walls are formed by aluminum alloy. Formwork, floor formwork, internal corner formwork, corner formwork, and wall column end formwork are combined and installed as a wall frame, and the reinforced concrete structure wall is cast and formed. Reduce the thickness of the load-bearing wall to save construction costs and increase the usable area of ​​the building. [0003] Among them, there are two construction methods for changing the thickness of the load-bearing wall. One is to replace the inner and ou...

Problems solved by technology

[0003] Among them, there are two construction methods for changing the thickness of the load-bearing wall. One is to replace the inner and outer combined wall formwork and floor formwork of different sizes. figure 1 ), the disadvantage of this construction method is that for each variable thickness wall, a large number of wall formwork and floor formwork need to be replaced, resulting in reduced construction efficiency and increased labor costs, resulting in low generalization rate of standard formwork and high overall cost; the second is to replace Different sizes of wall-to-wall, wall-to-floor internal corner templates (see the attached manual figure 2 ), this method needs to replace all the internal corner forms involved in changing the thickness of the wall and the corner formwork at the intersection of the three internal corners of the wall and the floor, and needs to increase the specifications and varieties of the internal corner formwork, the number of molds and the inventory. As a result, the operation is more difficult, the construction efficiency is lower, and the labor intensity and comprehensive cost are still high
