Abstract
The utility model discloses a putty type self-adhesive water-swelling sealing strip, which comprises a swelling sealing strip body and a self-adhesive layer; the expansion water stop strip body is integrally square and comprises a rubber framework and an outer expansion water stop layer, the rubber framework is H-shaped, and the outer expansion water stop layer is covered outside the inner rubber framework to form a sandwich structure; the self-adhesive layer is arranged at the bottom of the expansion water stop strip body. The water-stopping expansion water-stopping device is reasonable in structural design, water absorption expansion water stopping is realized through the outer expansion water-stopping layer, integral structural support is realized through the rubber framework, auxiliary sealing is realized through the extending part, and better water stopping is realized and durability is ensured.
Description
Technical Field
The utility model relates to a water stop strip, in particular to a putty type self-adhesive water-swelling water stop strip with an improved structure.
Background
The water-swelling sealing strip, also called a slow-swelling rubber sealing strip, is a strip-shaped rubber sealing material prepared by reacting natural rubber, an inorganic water-absorbing material and high-viscosity resin. The water stop strip is widely applied to construction joints, expansion joints and cracks of civil air defence, swimming pools, sewage treatment projects, underground railways, tunnels, culverts and the like and other concrete projects.
In the water-swelling sealing strip, the putty type water-swelling sealing strip has high swelling multiplying power and strong mobile replenishment, has strong balanced self-healing function after being placed in a construction joint, can automatically seal new tiny cracks caused by settlement, and can be used for stopping leakage again in finished engineering such as gap seepage and leakage.
The existing putty-type self-adhesive water-swelling water stop bar is simple in structure in autumn and mostly in a simple square shape, and in the actual use process, water stop and service life are insufficient to a certain extent, so that great improvement space and needs still exist.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects in the prior art and provides a putty type self-adhesive water-swelling water stop strip with an improved structure.
In order to achieve the purpose, the technical scheme adopted by the utility model is as follows: a putty type self-adhesive water-swelling sealing strip comprises a swelling sealing strip body and a self-adhesive layer; the expansion water stop strip body is integrally square and comprises a rubber framework and an outer expansion water stop layer, the rubber framework is H-shaped, and the outer expansion water stop layer is covered outside the inner rubber framework to form a sandwich structure; the self-adhesive layer is arranged at the bottom of the expansion water stop strip body.
Furthermore, the four ends of the rubber framework extend out of the outer expansion water stop layer.
Furthermore, the upper edge and the lower edge of the outer expansion water stop layer are provided with edge expansion water stop strips, and the edges of the edge expansion water stop strips are triangular.
Furthermore, the left end surface and the right end surface of the outer expansion waterproof layer are arc-shaped and convex.
The water-stopping expansion water-stopping device is reasonable in structural design, water absorption expansion water stopping is realized through the outer expansion water-stopping layer, integral structural support is realized through the rubber framework, auxiliary sealing is realized through the extending part, and better water stopping is realized and durability is ensured.
