Example Embodiment

[0015] In the following, the method for controlling the steel protection layer of the fair-faced concrete wall column provided by the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments. According to the following description and claims, the advantages and features of the present invention will be clearer. It should be noted that the drawings all adopt a very simplified form and all use imprecise ratios, which are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0016] The core idea of ​​the present invention is that the method for controlling the steel protection layer of fair-faced concrete wall pillars can improve the appearance quality of fair-faced concrete, keep the surface color of fair-faced concrete consistent without obvious color difference, no obvious cracks, uniform and small bubbles, and after demolding The surface is flat and s...

Abstract

The invention provides a method for controlling a bare concrete wall column reinforcement protective cover. The method comprises the steps that a galvanized steel pipe or a PVC pipe is arranged in advance for concrete pouring, the galvanized steel pipe or the PVC pipe are pulled upwards every time concrete with the thickness ranging from 500 mm to 600 mm is poured, and bubbles generated during concrete pouring disperse from the galvanized steel pipe or the PVC pipe; when concrete pouring is finished, the galvanized steel pipe or the PVC pipe is pulled out completely. According to the method for controlling the bare concrete wall column reinforcement protective cover, the appearance quality of the bare concrete is improved, the surface color of the bare concrete is kept consistent, no obvious color difference exists, no obvious cracks exist, the bubbles are uniform and tiny, the surface is flat and smooth after mold release, no oil stains or rusty spots or powdered objects exist, meanwhile, it is ensured that the thickness of the protective cover can meet the design requirement, and therefore durability of the concrete is improved.

Description

technical field [0001] The invention relates to the field of architectural engineering design, in particular to a method for controlling the steel bar protective layer of fair-faced concrete wall columns. Background technique [0002] At present, in addition to high requirements on geometric dimensions, concrete appearance quality requires consistent color, no obvious color difference and surface rust spots, and the area and depth of surface air bubbles are strictly controlled. In the past, the protective layer of the project mainly used conventional concrete or plastic pads to control the concrete protective layer. This construction method is easy to cause: first, the protective layer pads are exposed, which is inconsistent with the surface color of the newly poured concrete; The fixation is not firm, and the thickness cannot be guaranteed, which affects the durability of the concrete; the third is that due to the high sealing requirements of the fair-faced concrete wall co...
