Design and implementation method of novel waterproof structure for building sedimentation post-cast strip

Abstract

The invention aims to provide a design and implementation method of a novel waterproof structure for a building sedimentation post-cast strip. According to the technical scheme, building design, building construction and building material technologies are integrated, and the waterproof function of the building sedimentation post-cast strip is ensured. A first structure (a bottom plate post-cast strip structure at the junction of a high layer and a podium) of the building sedimentation post-cast strip mainly comprises five parts of a foundation mat layer, a sponge bar for increasing elongation,a waterproof coil layer, a sliding metal isolation layer and an expansion anti-permeable concrete layer.

Description

technical field [0001] A new type of waterproof structure design and implementation method of the post-settlement pouring belt of the present invention adopts the structural measures of increasing the elongation of the coiled material and reducing the friction between the coiled material and the concrete, that is: a new type of waterproof structure design of the post-settlement pouring belt of the building And the implementation method avoids the leakage caused by the shearing damage of the waterproof membrane. Background technique [0002] Leakage in the basement of construction projects in my country is a common quality problem, especially at the junction of high-rise buildings and podiums or complex foundations or basement floors and exterior walls with large foundation areas need to be equipped with post-settlement pouring belts. [0003] The post-settlement pouring belt is generally poured after the completion of the high-rise building structure, but due to the continuo...

AI Technical Summary

Problems solved by technology

[0003] The post-settlement pouring belt is generally poured after the completion of the high-rise building structure, but due to the continuous increase of live loads such as secondary structures and decoration works, the post-settlement pouring belt is still affected by uneven settlement, and it is very easy to waterproof the post-casting belt Concrete Shear Cracks

[0004] Due to the fact that the membrane waterproof layer at the pouring belt after settlement is under a huge load of friction between the cushion and the concrete protection layer, it cannot display the characteristics of elongation. When uneven settlement occurs, the elongation of the membrane waterproof layer is not enough to resist The amount of shear will cause damage and water seepage, which will seriously affect the function of use
