Construction process of concrete steel formwork

Abstract

The invention discloses a construction process of a concrete steel formwork. The construction process of the concrete steel formwork comprises the following steps of formwork design, formwork assembling, formwork splicing, prefabrication preparation, inspection and correction, concrete pouring, concrete vibrating, concrete curing, strength testing, cast part taking through formwork disassembling,and steel formwork maintenance. According to the construction process of the concrete steel formwork, a column formwork and column loops are mounted, an upper end formwork and a lower end formwork arefastened through screws, and fasteners such as U-shaped clamps and disc-shaped fasteners of hook bolt outer pads are used for fastening, so that deformation of the whole steel formwork is avoided inthe construction process, and concrete can be fixed more firmly; a demolding isolation agent of the steel formwork is processed, so that concrete is prevented from being left on the steel formwork after demolding; water is poured for wetting, so that the situation that moisture of the concrete is absorbed by the steel formwork, and consequentially, the concrete is not compact, and a pitted surfaceis caused is avoided, and the forming quality and strength of the concrete are improved; and meanwhile, a plastic film is used for maintenance in the seventh step, so that water losses are avoided while heat preservation is achieved.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a construction technique of a concrete steel formwork. Background technique [0002] Concrete steel formwork is a steel formwork used for concrete pouring and forming. After the steel formwork structure concrete is poured and formed, an ideal rough interface can be formed. In construction projects, steel formwork is used for its multiple uses and beautiful concrete pouring. Widely used, in the existing concrete steel formwork construction technology, there is no improvement in the concrete fixing and form removal process, the concrete is easy to remain, causing environmental pollution and corrosion to the steel formwork, and in the existing concrete steel formwork construction technology, Concrete is internally hardened in a short period of time, and it is prone to not being compacted.

[0002] Concrete steel formwork is a steel formwork used for concrete pouring and forming. After the steel formwork structure concrete is poured and formed, an ideal rough interface can be formed. In construction projects, steel formwork is used for its multiple uses and beautiful concrete pouring. Widely used, in the existing concrete steel formwork construction technology, there is no improvement in the concrete fixing and form removal process, the concrete is easy to remain, causing environmental pollution and corrosion to the steel formwork, and in the existing concrete steel formwork construction technology, Concrete is internally hardened in a short period of time, and it is prone to not being compacted. After the formwork is removed, the surface of the concrete will appear pitted, which will affect the overall project quality. At the same time, the existing concrete steel formwork construction process is not good enough for the concrete curing process. Concrete building parts are easy to crack and damage, and the water loss is serious. Therefore, the present invention proposes a construction process of concrete steel formwork to solve the problems existing in the prior art
