1 results about "Longitudinal contraction" patented technology

This utility model discloses a wall longitudinal contraction joint edge-sealing device, belonging to the field of contraction joint technology. Its key technical features include two longitudinal wall bodies, with a water-stopping mechanism positioned between opposite sides of the two longitudinal wall bodies. A decorative cover body is positioned on the front side of each longitudinal wall body, and pulling mechanisms are positioned at the top and bottom of the rear side of the decorative cover body. The water-stopping mechanism includes four screws, two fixing frames, a water-stopping strip body, and two protrusions. The surface of the water-stopping strip body contacts the inner wall of the fixing frames. This solves the problem that in existing longitudinal wall contraction joint edge-sealing devices, the water-stopping strip, after installation, directly and tightly contacts the edge of the longitudinal wall. The rough and sharp edges of the wall can easily cause localized pressure damage to the rubber water-stopping strip, affecting the waterproofing effect. Furthermore, it is inconvenient to open the decorative cover, making it difficult to replace the aged water-stopping strip after long-term use.
