Anti-seepage structure for post-cast strip of outer wall

Abstract

The outer wall post-cast strip anti-seepage structure is characterized in that an inserting plate is inserted into one end of an L-shaped connecting column, and an anti-seepage assembly is arranged between the inserting plate and the L-shaped connecting column; the anti-seepage assembly comprises a rubber sleeve, the rubber sleeve is a conical sleeve, a conical groove is formed in one side of the L-shaped connecting column, the rubber sleeve is fixedly connected to the interior of the conical groove, and the gap between the rubber sleeve and the conical groove is filled with two air bags. The rubber sleeve in the conical groove is pushed to expand and sleeve the outer side of the insertion plate to seal the insertion plate, and along with deep movement of the insertion plate, the insertion plate extrudes the two air bags, so that the air bags are stacked at the notch of the conical groove to extrude the rubber sleeve, the rubber sleeve is tightly attached to the outer side of the insertion plate, and the sealing performance between the insertion plate and the L-shaped connecting column is improved; and concrete between the L-shaped baffle and the inserting plate is prevented from leaking to the post-cast strip, and operation is easy and convenient.

Description

technical field [0001] The invention relates to the field of post-cast strips for exterior walls, in particular to an anti-leakage structure for post-cast strips for exterior walls. Background technique [0002] According to the requirements of the design or construction specifications, the concrete strips left at the corresponding positions of the foundation floor, walls, and beams are called post-cast strips. When pouring waterproof concrete, certain technical measures should be taken to ensure the structural waterproof quality of the post-cast strips. Traditional The post-pouring belt of the basement exterior wall usually uses multiple baffles to separate the concrete. Since there are gaps between the concrete baffles, the concrete and water will flow into the post-casting zone through the baffles, and the existing The width of the anti-seepage baffle of the post-casting tape is single and fixed, and the width of the baffle cannot be adjusted freely according to different...

[0002] According to the requirements of the design or construction specifications, the concrete strips left at the corresponding positions of the foundation floor, walls, and beams are called post-cast strips. When pouring waterproof concrete, certain technical measures should be taken to ensure the structural waterproof quality of the post-cast strips. Traditional The post-pouring belt of the basement exterior wall usually uses multiple baffles to separate the concrete. Since there are gaps between the concrete baffles, the concrete and water will flow into the post-casting zone through the baffles, and the existing The width of the anti-seepage baffle of the back-casting tape is single and fixed, and the width of the baffle cannot be adjusted freely according to different needs. Therefore, a leak-proof structure of the post-casting tape on the exterior wall is proposed
