Problems solved by technology

However, the concrete formwork is only a square or square formwork. Although the formwork can be made in the factory, it still needs a lot of assembly at the construction site. The construction efficiency is low, and there is still room for further improvement.

Embodiment 1

[0072] The construction method of the shear wall concrete formwork provided by the present embodiment comprises the following steps:

[0073] S1: Stitching templates, such as figure 1 As shown, the standardized concrete formwork 1 is spliced ​​into a pre-designed shear wall formwork 100. The concrete formwork 1 can be a concrete formwork in the prior art, but it needs to be ensured that one side is a smooth surface, which is compatible with the concrete when pouring concrete grout. The slurry contacts and forms the surface of the condensed building component, and the other surface needs to be provided with quick-connect grooves or similar structures so that various fixtures can be installed. The concrete formwork 1 used in this embodiment is a Chinese utility model patent ZL201220200056. 8 disclosed concrete formwork, its structure is as figure 2 As shown, the size can be set according to actual needs. The shear wall formwork 100 is closed, and its closed interior forms a c...

Embodiment 2

[0089]The difference between this embodiment and Embodiment 1 is that in step S3, the gap in the horizontal direction between the concrete forms 1 on the same plane is also adjusted, and the adjustment method includes the following steps:

[0090] a. In step S3, after installing the horizontal fixed pipe 5, ensure that the horizontal fixed pipe 5 can move along its length direction under a predetermined force. The specific installation method is to lock the horizontal fixed pipe 5 on the concrete with the screw 6 On the formwork 1, properly control the locking force of the screw 6 so that it will not lock the horizontal fixing pipe 6 and the concrete formwork 1 too tightly. Move, the installation hole that is used for locking screw 6 on the horizontal fixed pipe 5 needs to be slightly larger than the outer diameter of screw 6, preferably be designed as the waist-shaped hole that the longitudinal direction is consistent with the horizontal fixed pipe 5 lengthwise. In addition, ...

Embodiment 3

[0097] The difference between this embodiment and Embodiment 1 is that the concrete formwork 1 used in this embodiment is further improved on the basis of the concrete formwork disclosed in Chinese utility model patent ZL201220200056.8, which is disclosed in Chinese utility model patent ZL201220200056. In 8, the splicing surface of the concrete formwork 1 and its smooth surface are perpendicular to each other, that is, there is an angle of 90° between them. It is not convenient to disassemble after pouring concrete, and a large disassembly force is required. In this embodiment, the angle between the joint surface of the concrete formwork 1 and its smooth surface is changed from 90° to 45°. Those skilled in the art can also design the clamps of only part of the splicing surface of the concrete formwork 1 and its smooth surface to be 45° according to the actual dismounting force, and the other splicing surfaces are still at an angle of 90°.

Abstract

The invention provides a construction method of a shear wall concrete formwork with higher utilization efficiency, which includes the steps of splicing formwork, fixed spacing, horizontal reinforcement, longitudinal reinforcement, integral hoisting, pouring shear wall, and removal of formwork. Concrete formwork is spliced, and the splicing efficiency is high. At the same time, because the standardized concrete formwork can be reused, the use efficiency is higher. The spliced ​​shear wall formwork can be used repeatedly in the shear wall construction of each floor. The invention also provides a column construction method similar to the construction method of the shear wall formwork. With this method, the splicing of the shear wall formwork and columns can be prefabricated in a factory outside the construction site without occupying the operating space on the construction site, and the shear wall formwork can be directly installed and used after being hoisted to the construction site without splicing again , Improve the construction efficiency of the construction site.

Description

technical field [0001] The invention relates to a construction method of a concrete building component, in particular to a construction method of a concrete formwork for a shear wall and a concrete formwork for a column. Background technique [0002] A large number of formwork is used in the process of prefabricating concrete components. Because different shapes of buildings use different concrete formwork, most of the formwork cannot be reused, resulting in great waste; for this purpose, standardized formwork units are used, and the formwork units can be repeated. Use and can be spliced ​​into concrete formwork of various shapes. [0003] Chinese invention patent ZL93103864.2 discloses a cement concrete formwork and its pouring construction method. The standard formwork formed by plastic or metal is connected to each other to form building components of different shapes, such as models of columns, beams, walls, ceilings, etc. For pouring cement concrete slurry, the formwor...
