Basement external wall post-cast strip construction method and building structure thereof

Abstract

The invention discloses a basement external wall post-cast strip construction method and a building structure thereof. The construction method comprises the steps that when an exterior wall is cast, aguide wall is cast on the outer side of a post-cast strip, and waste generated during wall body casting and or excess materials left by wall body casting are used as materials of the guide wall. Thebuilding structure comprises the exterior wall. The guide wall is cast on the outer side of the post-cast strip. The waste generated during wall body casting and or the excess materials left by wall body casting are used as materials of the guide wall. The construction progress is greatly accelerated, the project quality is improved, due to the fact that the strength of the guide wall is high, theguide wall is not liable to collapse even under the action of pressure of backfill, the potential safety hazards are eliminated, meanwhile, bricks do not need to be purchased additionally, the building cost is reduced, the waste generated during wall body casting and or the excess materials left by wall body casting are used for a new purpose, waste is avoided, and in addition, extra cost is reduced. Natural stretching and contracting of the exterior wall and the guide wall are facilitated.

Description

technical field [0001] The invention relates to a construction method of a basement exterior wall and a building structure thereof, in particular to a construction method of a back-casting belt for the basement exterior wall and a building structure thereof. Background technique [0002] The post-casting belt is a temporary construction joint set up to overcome the harmful cracks that may occur due to temperature and shrinkage during the construction of the cast-in-place reinforced concrete structure. The joint needs to be reserved for a period of time according to the design requirements and then poured to connect the entire structure into a whole. [0003] like figure 1 As shown, in the prior art, the construction method of the post-casting zone is that after pouring the outer wall 1, the outer side of the reserved post-casting zone 2 is built with bricks to form a fence 3', backfill soil, and the post-casting zone is reserved. The inner support form of position 2 is pou...

AI Technical Summary

Problems solved by technology

Such a construction method has greatly affected the progress of the construction and the quality of the project.

Due to the low strength of the fence, the fence may collapse under the pressure of the backfill soil, which poses a great safety hazard

At the same time, additional bricks need to be purchased, which increases the construction cost

The waste generated when pouring the wall and / or the remaining material after pouring the wall must be cleaned up, which increases the transportation cost, or is buried as backfill, resulting in a great waste of construction materials
