Embodiment Construction

[0016] Combine below figure 1 Describe in detail the construction process of the post-pouring tape on the exterior wall of the basement.

[0017] The construction process of the basement external wall post-pouring tape includes the following steps:

[0018] 1) Build shale solid brick masonry 4 at the post-casting zone 2 of the basement exterior wall 1;

[0019] 2) Construction of exterior wall waterproof membrane 5;

[0020] 3) Backfill soil.

[0021] Wherein, the whole body 4 is provided with steel bar tension connection. The surface of the masonry 4 is painted with double-sided cement mortar 6 . The thickness of the basement exterior wall 1 is 350 mm, the width of the post-casting strip 2 is 800 mm, the masonry is U-shaped, the inner side of the masonry is 0.8 m away from the basement exterior wall, and the distance between the left and right sides of the masonry is the post-casting strip 300mm on both sides, and the thickness of the masonry is 240mm. A steel plate wat...

Abstract

The invention discloses basement exterior wall post-cast strip construction technology. The basement exterior wall post-cast strip construction technology includes the steps: 1) building a shale and solid brick masonry at the position of a basement exterior wall post-cast strip; 2) performing exterior wall waterproof roll construction; and 3) backfilling. Since construction is performed by using the masonry for protecting the post-cast strip, the basement exterior wall post-cast strip construction technology is convenient, rigidity is increased, and safety is higher.

Description

technical field [0001] The invention relates to a construction technology of a post-cast belt on an outdoor wall of a basement. Background technique [0002] At present, the construction of the post-cast belt of the basement exterior wall generally adopts the advanced water-stop method, that is, during the construction of the foundation raft, the area of ​​the post-cast belt is correspondingly increased with reinforcement and vertical rubber water-stop plates, and the structural shear wall is constructed at the same time. [0003] Due to the production of additional steel bars, there is a certain degree of difficulty. The fixed cost of the rubber waterstop is high, the amount of concrete increases, and there are many processes, which also affect the time. In addition, the mold may explode when the concrete is poured. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a construction process of the post-cast belt on t...
