Single-side support formwork structure and construction method for reinforcement construction of enlarged section

Abstract

The invention discloses a one-side support formwork structure for enlarging a section and strengthening construction and a construction method. The structure comprises a side formwork assembly, anchor ribs implanted in an original concrete wall surface and pulling and connecting assemblies pulled and connected between the side formwork assembly and the anchor ribs, a pouring space for pouring strengthened structures is formed between the side formwork assembly and the original concrete wall surface, and each pulling and connecting assembly is provided with a top formwork rib which abuts against the inner side of the side formwork assembly. According to the one-side support formwork structure for enlarging the section and strengthening construction and the construction method, due to the fact that the anchor ribs are implanted in the original concrete wall surface, the pulling and connecting assemblies are welded to the anchor ribs, side plate assemblies are pulled and connected to the anchor ribs through the pulling and connecting assemblies, and the pouring space for pouring the strengthened structures is formed between the side formwork assembly and the original concrete wall surface, the difficulty of strengthening of the one-side support formwork structure in the strengthening project can be solved by means of matching of the anchor ribs and the pulling and connecting assemblies, and meanwhile the pulling and connecting strength of the side plate assemblies and the original concrete wall surface is improved.

Description

technical field [0001] The invention relates to the field of engineering construction, in particular to a single-side support formwork structure and a construction method for reinforcement construction with enlarged sections. Background technique [0002] In existing structural reinforcement projects, the cross-section of concrete vertical members is enlarged, and the traditional formwork methods often have the following types: [0003] 1. Look for the original split bolt holes and wear the split bolts, but the original bolt holes are often blocked by debris and cannot be penetrated, and formwork reinforcement cannot be performed; [0004] 2. Set up one-sided formwork braces to reinforce the formwork, but the stability of the braces is poor, it is easy to cause mold expansion, it is difficult to control the flatness, and the molding quality is not good; [0005] 3. Re-drilling holes on the original structural members is often difficult due to the thick thickness of the orig...
