Problems solved by technology

[0002] In the prior art, the single-side formwork of the underground concrete structure wall is installed by pre-embedding iron parts or steel bars on the structural floor, and using full scaffolding and diagonal steel pipes to form a truss for support. Therefore, the steel pipe truss requires a large number of scaffolding pipes and buckles. It takes a long time to set up and requires a lot of labor, but in the end it is impossible to avoid the common problems of the verticality and flatness of the wall, and the quality of the wall is poor.

Embodiment Construction

[0020] The present invention is further illustrated below by specific examples.

[0021] Such as figure 1 , figure 2 and image 3 As shown, a method for installing a concrete wall formwork on one side comprises the following steps;

[0022] Step 1. When constructing the lower underground concrete structure 10, bury the iron piece 2 at the bottom of the vertical reinforcement 5 near the outside of the structure;

[0023] Step 2. Weld the bottom end of the lower pull screw rod 3 on the iron piece 2;

[0024] Step 3. Weld the bottom end of the upper pulling screw rod 4 to the H-shaped steel or steel sheet pile or the main reinforcement of the continuous wall in the foundation pit enclosure structure. The welding point 8 formed must be outside the scope of this pouring, that is, the welding point 8 It must be above the concrete pouring height of 20°C;

[0025] Step 4, install formwork component 7 from bottom to top;

[0026] Step 5. Connect and fix the formwork components i...

Abstract

The invention relates to the field of concrete structure wall construction, in particular to an installation method for a one-side formwork of a concrete wall. The method is characterized by including the steps that step1, an iron part is embedded into the top of an ungrounded concrete structure on the lower layer; step2, lower split lead screws are welded to the iron part; step3, upper split screw rods are welded to a foundation pit support structure, wherein the height of welding points should be larger than the concrete pouring height; step4, a formwork assembly is installed; step5, the formwork assembly in the step4 is connected and fixed through the split screw rods; step6, concrete is poured; step7, the welding points between the upper split screw rods and the foundation pit support structure are cut off, and then the work is completed. The construction method is simple and easy to understand, solves the common problem that due to the one-side formwork, the verticality and flatness of the underground concrete structure wall are out of tolerance and improves the appearance quality of the wall.
