Construction method of vertical face exposed aggregate concrete wall

Abstract

The invention discloses a construction method of a vertical face exposed aggregate concrete wall. The method comprises the following steps of S1, supporting a pouring template; S2. producing a pouringpartition plate, wherein the pouring partition plate is made of a high-strength metal material with a smooth surface; S3, installing the pouring partition plate, and vertically placing the pouring partition plate in a pouring cavity of the pouring template before pouring, wherein independent exposed aggregate concrete pouring cavities and common concrete pouring cavities are formed on the two sides of the pouring partition plate; S4, pouring concrete, first pouring the exposed aggregate concrete, and then pouring common concrete; and S5, after the common concrete is initially set, pulling outthe pouring partition plate upwards, and in the process of pulling out the partition plate upwards, slightly tapping the outer side wall of the pouring template to improve the fusion degree of the bonding surface of exposed aggregate concrete and common concrete. According to the method, common concrete is poured in the inner layer, and the surface is filled with exposed aggregate concrete, so that the concrete wall body can exhibit rich texture and color effect without secondary decoration, and meanwhile, the inner and outer layer concrete is not prone to cracking and falling off and the like.

Description

technical field [0001] The invention belongs to the technical field of decorative concrete wall construction, and in particular relates to a construction method for a vertically exposed aggregate concrete wall. Background technique [0002] The exposed aggregate concrete body originated in the 1970s and was applied in China at the beginning of this century. In recent years, it has been widely used in road paving and urban squares. It has high durability, one-time molding, no need for secondary decoration, and water permeability. Good characteristics, is a good ground paving material. [0003] At present, exposed aggregate concrete is affected by the technology, and it is mostly used in plane paving projects, but less in vertical walls, and its application range is limited to a certain extent. Compared with fair-faced concrete walls, exposed concrete walls have the characteristics of rich colors and textures. [0004] The Chinese invention patent with the patent number of 2...

AI Technical Summary

Problems solved by technology

This kind of wall panel manufacturing method has the following defects: (1) make wall panels on the ground (plane construction), and then install the wall panels on the wall, the overall construction period is long, easy to fall off, and the area of ​​the wall panels cannot If it is too large, there are many joints; (2) The pouring period of the wallboard is long; it is necessary to wait for a period of time after the initial setting of the colored exposed aggregate concrete layer to pour the ordinary concrete, so as to avoid the excessive fusion of the colored concrete and the ordinary concrete; (3) The pouring process is difficult to control; if the colored concrete with exposed aggregates solidifies for too short a time and ordinary concrete is poured, the two types of concrete will be too blended and the color effect will be affected; The bonding surface of the concrete is not firm, and the wall is installed vertically. After a long time of use, the two kinds of concrete will separate or fall off.

This method takes a long time and is costly when pouring exposed aggregate concrete on the formed wall, and the exposed aggregate concrete on the surface layer is easy to crack and fall off between the printed wall
