Rear pouring band with prefabricated concrete edge sealing plate for basement outer shear wall

Abstract

The invention discloses a rear pouring band with a prefabricated concrete edge sealing plate for a basement outer shear wall, comprising a two-side coagulated wall body, transverse reinforcing steel bars, longitudinal reinforcing steel bars, an inner pouring template of the rear pouring band and a prefabricated concrete edge sealing plate. The invention can realize the synchronous deformation of the prefabricated concrete edge sealing plate and structural entities at two sides of the rear pouring band so as to realize tight fitting. The rear pouring band has the advantages of convenient construction and good waterproof effect.

Description

Technical field: [0001] The invention relates to a basement outdoor shear wall post-cast belt, in particular to a basement outdoor shear wall post-cast belt with a prefabricated concrete edge-sealing plate. Background technique: [0002] In the construction of construction projects, the waterproof construction of the basement and the surrounding backfill soil generally need to be carried out after the post-pouring belt is poured and closed, and the post-pouring belt is generally placed 60 days after the concrete pouring of the basement outdoor wall according to the design requirements. Or the closed construction of the post-cast belt can only be carried out after the structure is capped, and the waterproof construction and earthwork backfilling of the outer side of the basement exterior wall can be carried out after the closed construction of the post-cast belt is completed, which greatly affects the construction progress. In order to solve this problem, the method of brick ...

Problems solved by technology

[0002] In the construction of construction projects, the waterproof construction of the basement and the surrounding backfill soil generally need to be carried out after the post-pouring belt is poured and closed, and the post-pouring belt is generally placed 60 days after the concrete pouring of the basement outdoor wall according to the design requirements. Or the closed construction of the post-cast belt can only be carried out after the structure is capped, and the waterproof construction and earthwork backfilling of the outer side of the basement exterior wall can only be carried out after the closed construction of the post-cast belt is completed, which greatly affects the construction progress

In order to solve this problem, the method of brick retaining wall is generally adopted in the prior art to close the outer wall gap of the basement outdoor wall at the post-casting belt, and then carry out earthwork backfilling on the outer side of the basement outdoor wall. Work, this construction method is not only complicated, but also affects the construction of the subsequent basement waterproofing project, and the pouring construction of the post-pouring belt in the later stage is very inconvenient, its waterproof effect is poor, and water leakage is prone to occur

In addition, precast concrete slabs are also used for post-cast edge banding. The four corners of the precast concrete slab are welded with the steel bars of the shear wall and installed close to the shear wall. This method is convenient for construction and improves the waterproof effect. However, its installation adopts the rigid connection method of welding with the shear wall reinforcement, which cannot make the structural entities on both sides of the precast concrete edge banding plate and the post-cast belt realize three-dimensional movement, so there are also quality defects
