[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0023] It should be noted that the terms "upper", "lower", "inside", "outside", etc., which are used to indicate orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. This is only for the convenience of describing the technical solution of the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the solution of the utility model.
[0024] like Figure 1 to Figure 4 As shown, a serrated self-adhesive waterstop comprises a base belt, wherein the base belt comprises a middle stretch belt 1 and side wing belts 2 which are integrally formed and connected; the side wing belts 2 are symmetrically arranged on both sides of the middle stretch belt 1.
[0025] In order to improve the stretchability, the upper surface of the middle stretching belt 1 is provided with an upward ridge 1a, and the corresponding position of the lower surface is provided with an upward groove 1b, the number of the upward ridge 1a and the upward groove 1b are both ≥2, and a front and rear through hole 1c is provided between the upward ridge 1a and the upward groove 1b; through the above scheme, the middle stretching belt 1 has a strong ability to adapt to stretching and extrusion deformation, and the waterstop belt can better adapt to and resist deformation when stretched, thereby maintaining its water-stopping effect. In the deformation joint of the building, placing the middle stretching belt 1 in the middle of the deformation joint can ensure that the product plays a good water-stopping role.
[0026] An array of serrations 2a is provided on the upper surface of the wing strip 2, the apex of the serrations 2a being lower than the apex of the upward convex ridge 1a. The design of the serrations 2a increases the contact area between the water stop strip and the building, thereby improving the friction. A glue groove 2b is provided on the lower surface of the side band 2, and an adhesive bag 2c is provided between the serration 2a and the glue groove 2b. The adhesive bag 2c includes a hollow cavity 2c-1, and an adhesive film 2c-2 is provided in the hollow cavity 2c-1. The adhesive film 2c-2 is filled with adhesive liquid, and a glue outlet opening 2c-3 is provided at the bottom of the hollow cavity 2c-1. A nail 2c-4 is provided above the adhesive film 2c-2, and the nail tip of the nail 2c-4 is set downward, and the root thereof is connected to the hollow cavity 2c-1. The glue groove 2b includes intersecting longitudinal grooves and transverse grooves, and the longitudinal grooves and the transverse grooves are staggered into a grid structure. The intersection points of the two are connected to the glue outlet opening 2c-3, so the number of intersection points of the longitudinal grooves and the transverse grooves is equal to the number of the adhesive film 2c-2. When in use, the nail 2c-4 is squeezed downward, and the glue liquid flows out from the damaged wrapping film 2c-2 and fills the criss-cross glue grooves 2b through the glue outlet opening 2c-3.
[0027] A serrated self-adhesive waterstop in the present technical solution can fit tightly into the gaps in the building structure through its self-adhesiveness to form a tighter waterproof layer, thereby effectively preventing water penetration and leakage. The use of the waterstop needs to follow certain steps and precautions to ensure its effectiveness and safety. The area needs to be cleaned before installation to ensure that the area where the waterstop needs to be installed is clean, and dust, oil and other impurities are reduced as much as possible. When the base tape is laid in place, the adhesive package 2c is squeezed downward from the top to make the nail 2c-4 penetrate the adhesive film 2c-2, and the adhesive flows out from the adhesive film 2c-2. The adhesive outlet opening 2c-3 fills the criss-crossing adhesive grooves 2b downward, and the adhesive flows evenly and forms a firm bond with the contact surface of the building after drying. Finally, the concrete needs to be fully shaken during pouring to ensure that the waterstop is tightly bonded to the concrete.
[0028] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited thereto. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the utility model, relevant changes, modifications or additions should all fall within the protection scope of the utility model.
