Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and specifically relates to a construction method for reinforcing the formwork of a filling wall anti-camber. Background Art

[0002] The anti-camber is an important waterproof foundation structure set at the partition wall of rooms with waterproof requirements in buildings. It usually protrudes from the floor surface. Therefore, the construction of the anti-camber is mostly completed by the method of formwork support and pouring. During the construction process, it is necessary to set the anti-camber formwork to shape the anti-camber. In order to ensure that the anti-camber does not bulge, it is usually necessary to reinforce the anti-camber formwork with a reinforcement fixture. However, simply using the reinforcement fixture is prone to deviation during the pouring process.

[0003] Based on this, in the existing technology, in order to prevent the anti-camber from deviating, the formwork is usually fixed by drilling holes in the floor and implanting steel bars. When drilling holes, the embedded pipeline in the floor is often damaged, and the repair of the pipeline is difficult. At the same time, it causes certain damage to the quality of the floor. Summary of the Invention
