Construction method for backward supporting aluminum alloy independent column with post-cast strip

Abstract

The invention discloses a construction method for backward supporting aluminum alloy independent column with a post-cast strip, and belongs to the technical field of building construction. The construction method aims at solving the problems that a traditional top plate post-cast strip supporting system occupies a large number of formworks and supporting materials for a long time, daily management difficulty is large, the supporting materials are extremely easy to damage and even are manually dismantled, the formworks, square timber, jacks and other materials are easy to deform, decay, rust and the like, so that the post-cast strip formwork supporting system is loosened. The method comprises the following steps that a 200 mm * 200 mm hole is reserved in the formwork splicing position to serve as an aluminum alloy stand column backward supporting position, an aluminum alloy independent column support is kept all the time, the aluminum alloy independent column cannot be dismounted halfway, whole-course supporting of the aluminum alloy independent column is achieved, and the aluminum alloy independent column can be dismantled until post-cast strip concrete pouring is completed and forced formwork dismantling is achieved. The method has the advantages of being high in construction speed, convenient to install, reliable in quality, economical, reasonable, high in applicability, wide in application range, green and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method of a back-top aluminum alloy independent column after pouring. Background technique [0002] During the construction process, the post-cast formwork bracket and the frames on both sides are installed and formed at one time, and support points should be added at intervals in the middle of the pouring plate after settlement to reinforce the formwork and support system. However, the template support frame of the post-casting belt should be set independently. The formwork on both sides can only be dismantled after the post-cast concrete is poured to ensure that the bottom of the slab is flat. The structures on both sides of the beam and slab in the post-cast belt span are under cantilever stress for a long time, so it is required that the formwork and supports in the span cannot be removed during construction, otherwise it may cause problems in th...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the traditional roof post-cast belt support system occupies a large number of templates and supporting materials for a long time, and the daily management is difficult. Deformation, decay, corrosion, etc., cause the problem of loosening of the support system of the post-cast belt formwork, and propose a construction method for post-cast belt back-top aluminum alloy independent columns
