[0024] In a specific embodiment, as shown in Figure 1 And 2 As shown, it comprises two waterstop bodies 1 and a deformation cylinder 3, the two waterstop bodies 1 are fixedly connected on the two sides of the deformation cylinder 3, and the top surface and the bottom surface of the two waterstop bodies 1 are fixedly connected with a plurality of waterproof strips 2; the waterstop body 1, the waterproof strip 2 and the deformation cylinder 3 are integrally formed and are all made of rubber material, the two waterstop bodies 1 are fixedly connected with two anti-skid plates 4 at the end away from the deformation cylinder 3, the two anti-skid plates 4 are provided with anti-skid parts at the ends away from each other, the anti-skid plate 4 is fixedly connected with an anti-skid strip 5 at the end away from the waterstop body 1, and the two anti-skid plates 4 on each waterstop body 1 are arranged at an angle; the deformation cylinder 3 is provided with a buffer assembly 6, and the buffer assembly 6 is used for buffering the tensile force of the two waterstops borne by the deformation cylinder 3.
[0025] In a specific embodiment, the buffer assembly 6 includes a buffer cylinder 601 and several connecting plates 602. The buffer cylinder 601 and the connecting plates 602 are arranged throughout and pass through the deformation cylinder 3. Several connecting plates 602 are arranged at equal intervals in the gap between the deformation cylinder 3 and the buffer cylinder 601. Each connecting plate 602 is arranged throughout the buffer cylinder 601 and one end is fixedly connected to the outer wall of the buffer cylinder 601. The other end of the connecting plate 602 is fixedly connected to the inner wall of the deformation cylinder 3.
[0026] By configuring the buffer tube 601 and the connecting plate 602, when the concrete structure changes, tension is first generated at both ends of the two waterstop bodies 1 and transmitted to the deforming tube 3, causing the deforming tube 3 to deform toward the waterstop bodies 1 on both sides. This in turn generates tension on the connecting plate 602, which in turn generates tension on the buffer tube 601, causing it to deform. This disperses the tension on the deforming tube 3, improves the tensile strength of the waterstop, protects the waterstop and the overall structure from damage, and extends its service life.
[0027] Specifically, there are four connecting plates 602 , two of which are vertically arranged and fixedly connected to both sides of the buffer cylinder 601 , and the other two connecting plates 602 are horizontally arranged and fixedly connected to both sides of the buffer cylinder 601 .
[0028] Specifically, the buffer tube 601 and connecting plate 602 are both made of rubber and are integrally formed with the deformable tube 3. The rubber material imparts elasticity to both the buffer tube 601 and connecting plate 602, enabling them to elastically deform under tension. The integral formation of the buffer tube 601, connecting plate 602, and deformable tube 3 enhances the connection strength between the buffer tube 601, connecting plate 602, and deformable tube 3.
[0029] In one embodiment, the cross section of the anti-slip strip 5 is a triangular structure, which can further enhance the contact area and connection strength between the anti-slip strip 5 and the concrete.
[0030] In one embodiment, Figure 2 As shown, the anti-slip portion includes a plurality of vertical bars 7 , and a plurality of horizontal bars 8 are provided between two adjacent vertical bars 7 . Both the vertical bars 7 and the horizontal bars 8 are made of rubber material and are integrally formed with the anti-slip plate 4 .
[0031] It should be noted that the angle between the two anti-skid plates 4 is not less than 30 degrees.
[0032] By providing the horizontal bars 8 and the vertical bars 7 , the friction between the anti-slip plate 4 and the concrete structure can be increased, thereby preventing the waterstop body 1 from sliding and falling off in the horizontal and vertical directions.
[0033] In one embodiment, Figure 3As shown, the anti-skid part comprises a corrugated strip 9 arranged along the length of the anti-skid plate 4, which is made of rubber and integrally formed with the anti-skid plate 4.
[0034] Through the arrangement of the corrugated strip 9, the same effect as the horizontal strip 8 and the vertical strip 7 can be achieved, preventing the waterstop body 1 from sliding and falling in the horizontal and vertical directions.
[0035] The working principle of the utility model is as follows: in the utility model, during construction, the embedded rubber waterstop is embedded in the joint, deformation joint or construction joint of the concrete structure, and as the concrete is poured and hardened, the waterstop is combined with the concrete, when the concrete structure is deformed due to thermal expansion and cold contraction or other external forces, the anti-skid plate 4, the anti-skid strip 5 and the anti-skid part on the anti-skid plate 4 can enhance the contact area and friction force between the two ends of the waterstop body 1 and the concrete structure, thereby enhancing the waterproof effect of the waterstop and the connection relationship with the concrete structure, ensuring the stability and durability of the entire waterstop structure and preventing the waterstop from moving.
[0036] The embodiments in the specification are described in a progressive manner, and each embodiment focuses on the difference from other embodiments, and the same or similar parts between the embodiments can be referred to each other.
[0037] The above-described embodiments are only used to describe the preferred modes of the utility model, and do not limit the scope of the utility model, and various modifications and improvements to the technical solutions of the utility model made by those skilled in the art without departing from the design spirit of the utility model shall fall within the protection scope of the utility model.
