The clamping strips 3 are in a T shape. Through the design of the T-shaped clamping strip 3 structure, the contact area between the waterstop and the concrete is greatly increased, while ensuring the firmness of the waterstop and improving the sealing performance of the waterstop, thereby more effectively preventing water penetration. A plurality of clamping strips 3 are symmetrically distributed on the left and right sides of the telescopic deformation tube 2. The lower end of the left side wall of the waterstop main body 1 is fixedly connected with a bottom connecting plate 6, and the upper end of the right side wall of the waterstop main body 1 is fixedly connected with a top connecting plate 11. The left end of the upper surface of the waterstop main body 1 is provided with an upper adhesive groove 10, and the right end of the lower surface of the waterstop main body 1 is provided with a lower adhesive groove 15. The top connecting plate 11 is adapted to the lower adhesive groove 15, and the bottom connecting plate 6 is adapted to the upper adhesive groove 10. A main adhesive layer 4 is arranged at the lower end of the waterstop main body 1, and a main release film 5 is arranged on the side of the main adhesive layer 4 away from the waterstop main body 1;
[0027] A snap-in groove 7 is provided at the left end of the waterstop body 1, and a snap-in plate 13 is fixedly connected to the right end of the waterstop body 1. The snap-in plate 13 is adapted to the snap-in groove 7, and the lower inner wall of the snap-in groove 7 and the upper end surface of the bottom connecting plate 6 are located in the same plane, and the lower end surface of the snap-in plate 13 and the upper inner wall of the lower pasting groove 15 are located in the same plane, so as to ensure the flatness of the upper and lower sides of the device when the bottom connecting plate 6 and the lower pasting groove 15 and the top connecting plate 11 and the upper pasting groove 10 cooperate;
[0028] The clamping plate 13 and the clamping slot 7 are both L-shaped;
[0029] The bottom connecting plate 6 and the inner side wall at the end of the lower clamping groove 7 are both provided with an auxiliary adhesive layer 1 8, and the lower end of the top connecting plate 11 is provided with an auxiliary adhesive layer 2 12. The outer ends of the auxiliary adhesive layer 1 8 and the auxiliary adhesive layer 2 12 are both provided with dustproof release films. When multiple waterstop belt bodies 1 are required to cooperate, the dustproof release films are torn off, and the bottom connecting plate 6 and the lower adhesive groove 15, and the top connecting plate 11 and the upper adhesive groove 10 are closely fitted under the action of the auxiliary adhesive layer 1 8 and the auxiliary adhesive layer 2 12, thereby ensuring the sealing of the connection between the two waterstop belt bodies 1;
[0030] A matching groove 9 is provided at the left end of the waterstop body 1, and an expansion waterstop strip 14 is fixedly connected to the right end of the waterstop body 1. When water accumulates and leaks at the position of the upper pasting groove 10 and the top connecting plate 11, the expansion waterstop strip 14 expands when it encounters water and fits tightly to the inner wall of the matching groove 9, thereby greatly improving the water-stopping effect of the device;

[0032] Working principle: When the paste type of the waterstop main body is required, tear off the main release film 5, and use the main adhesive layer 4 to paste the waterstop main body 1 at the wall gap. When multiple waterstops need to be used in cooperation, bring the two waterstops closer to each other. Through the cooperation of the bottom connecting plate 6 and the lower adhesive groove 15 of the two waterstop strips, the clamping plate 13 and the clamping groove 7 cooperate, and the top connecting plate 11 and the upper adhesive groove 10 cooperate, thus completing the splicing of the two waterstops. Under the action of the auxiliary adhesive layer 1 and the auxiliary adhesive layer 2, the firmness of the connection between the two waterstop main bodies 1 is improved. At the same time, the cooperation of the L-shaped clamping plate 13 and the clamping groove 7 further improves the firmness between the two waterstops, and can greatly improve the waterstop effect at the joint, effectively avoiding the problem of leakage at the joint; A fitting groove 9 is provided at the left end of the waterstop main body 1, and an expansion waterstop strip 14 is provided at the right end of the waterstop main body 1. During use, the expansion waterstop strip 14 is used in cooperation with the fitting groove 9. When water leaks at the position of the upper adhesive groove 10 and the top connecting plate 11, the expansion waterstop strip 14 swells when encountering water and tightly adheres to the inner wall of the fitting groove 9, thereby greatly improving the waterstop effect of the device.
