Post-pouring belt structure for outer wall of basement and construction method thereof

Abstract

The invention relates to a post-pouring belt structure for an outer wall of a basement, which comprises an outer wall of the basement and a post-pouring belt arranged on the outer wall of the basement, wherein a prefabricated plate is arranged on the outer side of the outer wall of the basement; the length of the prefabricated plate is larger than the width of the post-pouring belt; the prefabricated plate comprises a plurality of fixed plates with equal sizes; a connecting portion is arranged between adjacent fixing plates, and the connecting portion is used for connecting the adjacent fixingplates; a waterproof coiled material and a coiled material waterproof additional layer are sequentially arranged on the inner side of the prefabricated plate; a single-side template for plugging thepost-pouring belt is arranged on the inner side of the outer wall of the basement; a threaded rod perpendicular to the wall is embedded in the inner side and the outer side of the underground outdoorwall, and the threaded rods are located on both sides of the post-pouring belt; the prefabricated plate and the single-side template are mounted on the outer wall of the basement by means of a positioning nut and the threaded rod. The construction method has the advantages that the structure is simple, the construction is convenient, the waterproof performance of the post-pouring belt is improved,and the precast slab replaces the brick wall, so that workers can install the precast slab well before the construction, and the one-time installation is achieved in place during the construction, thereby shortening the construction period.

Description

technical field [0001] The invention relates to the technical field of post-cast belt construction, in particular to a post-cast belt structure and a construction method for a basement exterior wall. Background technique [0002] During the construction process of the basement, post-casting belts are often installed. According to the regulations, the post-casting belts can only be poured and closed after the main body of the structure is capped for 2 months. However, due to the different water levels in the construction area, it often brings a lot of leakage during the construction process. How to adopt a better construction method to avoid common construction problems is particularly important. [0003] At present, the conventional construction method is to build a brick wall on the outside of the post-cast belt of the basement exterior wall, and then perform plastering and waterproofing of cement mortar. However, the construction period of the above-mentioned construction ...

Problems solved by technology

[0003] At present, the conventional construction method is to build a brick wall on the outside of the post-cast belt of the basement exterior wall, and then perform plastering and waterproofing of cement mortar, but the construction period of the above-mentioned construction method is relatively long. However, there are still problems such as narrow space, limited height of bricklaying, difficult operation, and deformation of bricklaying when the backfill soil is rammed.
