Full water stopping side wall template system

Abstract

The invention discloses a full water stopping side wall template system. The full water stopping side wall template system is characterized in that a side wall template is a steel template, the back of the side wall template is provided with a triangular bracket which is composed of a vertical bar, a horizontal bar and an oblique brace, and the triangular bracket supports the side wall template triangularly. The side wall template and the vertical bar of the triangular bracket are connected into a whole by hook bolts; a pre-embedded anchoring bolt is arranged; and the pre-embedded anchoring bolt and the bottom part of the triangular bracket, which is near to the side wall, are anchored with a high-strength nut through an external-connection screw. Due to the adoption of the full water stopping side wall template system, the quality of the water-stopping engineering and the like can be ensured, the construction efficiency can be improved, and the construction cost can be reduced.

Description

technical field [0001] The invention relates to a side wall formwork system, more specifically, the formwork system is especially applied to the side wall concrete construction in subway stations and other places with strict waterproof requirements and complicated construction conditions. Background technique [0002] image 3 As shown, a certain subway station has a double-layer four-span cast-in-place frame structure, and the thickness of the side wall 4 is 800mm. Use the pull method to stand the mold. Therefore, construction joints shall be provided at the junction of the side wall and the floor slab, and the side wall shall be poured separately, using single-sided wall formwork. [0003] According to the existing structure, the side wall formwork uses bamboo plywood as the panel, square wood as the skeleton, steel pipes as the support, and the side wall formwork and the outside of the side wall are connected with water-stop bolts. The following problems exist in actual...

AI Technical Summary

Problems solved by technology

[0004] 1. The connection form of the side wall formwork and the outside of the side wall is connected by water-stop bolts. In actual construction, the water-stop effect of the water-stop bolts cannot guarantee to meet the requirements of project quality, and the cost is high;

[0005] 2. The installation density of supporting steel pipes is high, the disassembly and assembly procedures are cumbersome, and the construction efficiency is low;

[0006] 3. Since there are no good fixing measures at the bottom of the side wall, the formwork may float up under the action of steel pipe diagonal braces, which will affect the forming quality of the concrete;

[0007] 4. The bamboo plywood formwork has large joints, resulting in poor flatness of the concrete;

[0008] 5. The bamboo plywood formwork is easy to corrode and damage, and the reuse rate is low, which brings about an increase in cost
