Construction method of ultrahigh facing bare concrete vertical column

Abstract

The invention relates to a concrete vertical column construction process, in particular to a construction method of an ultrahigh facing bare concrete vertical column. A traditional concrete column construction process is integrated and improved through process optimization of all links such as the match ratio of bare concrete, quality control of raw materials, a material of formworks, a material of a release agent, formwork mounting and dismounting, pouring and vibration of the bare concrete, rain shed curing of the bare concrete, and protection of a finished bare concrete product. According to the process, the problems that as for a special-shaped facing bare concrete column, modelling construction is difficult, and the appearance quality is difficult to guarantee are effectively solved,it is guaranteed that the facing bare concrete is poured to be formed at a time, pitted surface bubbles are avoided, the color is uniform, and opposite joints of the formworks are regular and uniform,and have the mechanism and texture of the concrete.

Description

technical field [0001] The invention relates to a construction technique for a concrete column, in particular to a construction method for a super-high-faced fair-faced concrete column. Background technique [0002] Fair-faced concrete is a new, green, high-performance concrete that integrates structure and decoration. Economically, it is beneficial to save resources. The fair-faced concrete structure is no longer used for exterior decoration, which saves traditional decoration materials, which is of great significance to the conservation of natural resources, and does not require exterior decoration, which greatly reduces project costs. And as facing concrete, there is a higher standard in appearance quality than fair-faced concrete. [0003] With the rapid development of high-speed railway construction, the construction standards of railway stations and canopies are getting higher and higher. At present, most station platform canopies are in the form of steel structure c...

Problems solved by technology

[0004] The present invention is a construction method for super-high-decorated fair-faced concrete columns. This method is mainly aimed at the curved-surface and irregular-faced fair-faced concrete canopy project with complex shape and tight construction period, and the traditional construction method cannot meet the design appearance effect, and mainly solves the following problems : ① After the concrete pouring of super-high-finish fair-faced concrete columns, the surface color is uneven, and there are phenomena such as air bubbles and pockmarks; ② Because the columns are curved and special-shaped structures, ordinary wood formwork cannot achieve the appearance effect required by the design; ③ Due to the heavy steel formwork , the problem of missing edges and corners of facing concrete columns caused by difficult demolition
