[0024] By arranging the buffer assembly 3 and the internal compounded tensile strip 4 between the two water stop bodies 1, and arranging the non-slip plate 5 and the non-slip strip 6 on both sides of the water stop body 1, a whole tensile and non-slip structure is formed, which significantly improves the tensile performance, interface bonding strength and waterproof effect of the water stop, and solves the problems of easy breakage, sliding and insufficient waterproof performance of the traditional water stop.

[0025] In a specific embodiment, as shown in Figure 1 andFigure 2 As shown, the buffer assembly 3 includes a deformation cylinder 301 and a wire mesh cylinder 302, the deformation cylinder 301 is fixedly connected with the two waterstop bodies 1 respectively, and the wire mesh cylinder 302 is arranged in the deformation cylinder 301; the plurality of tensile strips 4 are all fixedly connected with the deformation cylinder 301 and the wire mesh cylinder 302 through the deformation cylinder 301.

[0027] In a specific embodiment, the tensile strip 4 is made of thermoplastic polyurethane material.

[0028] By using thermoplastic polyurethane TPU material to make the tensile strip 4, the high strength, high elasticity and wear resistance of TPU are utilized to significantly improve the tensile performance and durability of the waterstop, and to adapt to greater concrete displacement and complex stress state.

[0029] In a specific embodiment, as shown in Figure 1 and Figure 3 The connecting piece 7 includes a connecting plate 701, the connecting plate 701 is combined in the waterstop body 1, a plurality of mounting holes 702 are formed on the connecting plate 701 along the length direction of the connecting plate 701, and the mounting holes 702 are arranged through the waterstop body 1; the plurality of tensile strips 4 are fixedly connected with the connecting plate 701.

[0030] Through the mounting holes 702 on the connecting plate 701, the concrete can be connected through anchoring pieces such as bolts or steel bars, and the connecting plate 701 is fixedly connected with the tensile strips 4 to form an overall tensile structure.
