Construction method of overlong and superhigh single-side fair-faced concrete wall

Abstract

The invention relates to a construction method of an overlong and superhigh single-side fair-faced concrete wall. The method comprises the following steps of: (a) carrying out deepening design on a template drawing; (b) finishing binding shear wall reinforcing bars and welding positioning reinforcing bars; (c) mounting a template: mounting the template by dividing the template into a fair-faced template and an ordinary concrete template, mounting the fair-faced template firstly and then mounting the ordinary concrete template; (d) supporting and reinforcing the mounted templates; (e) pouring concrete into the templates: arranging a rear pouring band along the length direction of the concrete wall, and pouring by layers from top to bottom along the height direction of the concrete wall; (f) dismantling the templates to maintain the concrete; and (g) circularly using the dismantled templates on other construction sections according to construction requirements and repeating the steps from (b) to (f) to finish the construction of the whole wall body. The invention is suitable for the construction of the overlong and superhigh single-side fair-faced concrete wall, and not only guarantees the mounting quality of the fair-faced concrete template, but also reduces the construction cost.

Description

technical field [0001] The invention relates to a construction method for a concrete wall with a clear water finish, in particular to a construction method for an ultra-long and super-high single-sided clear water finish concrete wall. Background technique [0002] For the construction process of ordinary concrete walls, the formwork is generally installed first, then the concrete is poured, and finally it is removed for maintenance. However, for the construction of super-long and super-high single-sided fair-faced concrete walls, if traditional construction methods are used, there will be some problems: [0003] (1) Since the dry wall is super high and long, it is necessary to arrange the post-casting strips of the concrete wall reasonably, carefully plan the vertical and horizontal construction joints, and avoid a large number of construction joints, which will affect the construction effect of the dry wall; [0004] (2) The ultra-high-definition water-resistant concrete ...

Problems solved by technology

[0005] (3) It is difficult to control the verticality of the ultra-high-definition concrete wall, especially for multiple vertical pours, and the verticality of the formwork is prone to deviation;

[0006] (4) It is difficult to control the horizontal straightness and flatness of the ultra-high-definition water-resisting concrete wall, especially when pouring multiple times in the horizontal direction, the horizontal straightness of the formwork is prone to deviation;

[0007] (5) It is difficult to control the straightness of the vertical and horizontal open seams and the straightness of the bolt holes of the ultra-long ultra-high-definition concrete wall;
