Description

Technical Field

[0001] The utility model relates to the technical field of water stop belts, in particular to an externally bonded rubber water stop belt. Background Technique

[0002] The rubber water stop belt is mainly made of natural rubber and various synthetic rubbers, and is added with various additives and fillers. It is formed by plasticizing, mixing and pressing. It has many varieties and specifications. The externally bonded rubber water stop belt, also known as the back-bonded water stop belt or the external water stop belt, is a water stop structure arranged on the outer side (water-facing side) of the concrete deformation joint and settlement joint wall panel of underground structures. It has the ability to adapt to the expansion and contraction deformation of concrete with the elastic material and structural form of the water stop belt. The externally bonded rubber water stop belt utilizes the high elasticity of rubber to produce elastic deformation under various loads, so as to play a firm sealing role, effectively prevent the leakage and seepage of building structures and play a shock-absorbing and buffering role. In the design of many engineering buildings, there are certain expansion and contraction requirements between civil engineering and soil and water structures, and there are also problems such as waterproofing and earthquake prevention. Therefore, the adoption and installation of rubber water stop belts are effective means to solve the above problems.

[0003] At present, two water stop belts are usually bonded to each other with glue. The connection is unstable and easy to loosen and separate. Moreover, after the glue is applied and connected, it takes a long time to wait until the glue dries. Waiting at the construction site wastes time and reduces the normal construction efficiency. In addition, since the two water stop belts are bonded with glue and the glue has a certain shelf life, when the water stop belt is used for a long time, the glue will fail, and then cracks will appear in the two bonded water stop belts, causing water leakage. Content of the Utility Model

[0004] The purpose of the utility model is to provide an externally bonded rubber water stop belt to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: An externally bonded rubber water stop belt, including a water stop belt baseband, further comprising:

[0006] A clamping mechanism arranged outside the water stop belt baseband for connecting multiple water stop belt basebands. The clamping mechanism includes a first splicing block and a second splicing block fixed outside the water stop belt baseband. A clamping groove is opened at the bottom of the first splicing block, a clamping bar is fixed at the top of the second splicing block, the clamping bar is clamped on the inner wall of the clamping groove, a sealing groove is opened at the top of the clamping bar, and a sealing strip is fixed on the inner wall of the clamping groove. The sealing strip is clamped on the inner wall of the sealing groove.

[0007] Preferably, a reinforcing layer for improving its service life is fixed at the bottom of the water stop belt baseband, and the material of the reinforcing layer is set as a bendable waterproof aluminum plate.

[0008] Preferably, a plurality of sleeves are equidistantly arranged at the bottom of the reinforcing layer, and reinforcing ribs for improving the strength of the reinforcing layer are fixed to the inner wall of the sleeves.

[0009] Preferably, a protective layer is fixed to the bottom of the reinforcing layer, and fluorescent particles are arranged inside the protective layer.

[0010] Preferably, a wear-resistant layer for improving the wear resistance of the waterstop is fixed to the bottom of the protective layer, and the material of the wear-resistant layer is set as butyl rubber.

[0011] Preferably, a filling strip and a plurality of joint strips for facilitating fixation with concrete are respectively fixed to the top of the waterstop baseband.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] The present utility model can facilitate the connection of two adjacent waterstops by setting a clamping mechanism. Among them, two adjacent waterstops are connected by a first splicing block and a second splicing block. While being fixed with glue, the clamping strip is clamped and fixed with the clamping groove, so that the first splicing block and the second splicing block are fixed, preventing dislocation when the connecting glue is not dry, saving the time for waiting for the glue to dry, and improving work efficiency. By setting the clamping and fixing of the sealing groove and the sealing strip, the connection between the first splicing block and the second splicing block is more sealed. Even if cracks appear due to the failure of the glue in the later stage, the water will be blocked by the sealing groove and the sealing strip, and there will be no problem of water leakage.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-4 As shown, an externally attached rubber waterstop includes a waterstop baseband 1. By providing the waterstop baseband 1, it can prevent water or other liquids from penetrating into the joints of the building, ensuring the structural integrity and service life of the building. It also includes a clamping mechanism 2 provided on the outer side of the waterstop baseband 1 for connecting multiple waterstop basebands 1. By providing the clamping mechanism 2, it is convenient to connect multiple waterstop basebands 1, with convenient installation and time saving. The clamping mechanism 2 includes a first splicing block 21 and a second splicing block 22 fixed to the outer side of the waterstop baseband 1. By providing the first splicing block 21 and the second splicing block 22, it is convenient to splice two adjacent waterstop basebands 1. A card slot 23 is formed at the bottom of the first splicing block 21, and a card strip 24 is fixed to the top of the second splicing block 22. The card strip 24 is clamped to the inner wall of the card slot 23. By providing the card slot 23, it is convenient for the card strip 24 to be clamped thereto, thereby clamping and fixing the first splicing block 21 and the second splicing block 22. A sealing groove 25 is formed at the top of the card strip 24, and a sealing strip 26 is fixed to the inner wall of the card slot 23. The sealing strip 26 is clamped to the inner wall of the sealing groove 25. By providing the sealing groove 25, it is convenient for the sealing strip 26 to be hermetically clamped thereto, making the sealing performance better when the first splicing block 21 and the second splicing block 22 are joined, and thus making the connection waterproof sealing performance of the waterstop baseband 1 stronger and not easily causing water to flow out from the clamped gap.

[0021] Please refer to Figure 1 、 Figure 3 and Figure 4As shown, a reinforcing layer 3 for improving its service life is fixed to the bottom of the waterstop baseband 1. The material of the reinforcing layer 3 is set as a bendable waterproof aluminum plate. By setting the reinforcing layer 3, the service life of the waterstop baseband 1 can be improved; a number of sleeves 4 are equidistantly arranged at the bottom of the reinforcing layer 3, and reinforcing ribs 5 for improving the strength of the reinforcing layer 3 are fixed to the inner wall of the sleeves 4. By setting a number of sleeves 4 and reinforcing ribs 5 and using them in cooperation with the reinforcing layer 3, the structural strength of the waterstop is improved, making the waterstop more resistant to tensile tearing, preventing the waterstop from being pulled and broken due to the deformation of the building object during use and unable to be normally sealed, and improving the service life of the waterstop; a protective layer 6 is fixed to the bottom of the reinforcing layer 3, and fluorescent particles 7 are arranged inside the protective layer 6. By setting the protective layer 6 and the fluorescent particles 7 in cooperation, the structure of the waterstop is buffered and protected, making the waterstop more resistant to pressure, and when the waterstop has cracks, the fluorescent particles 7 are exposed, facilitating the staff to directly observe whether there is fluorescence on the surface of the waterstop to judge whether the waterstop is broken, preventing the staff from making mistakes due to the small fracture lines of the waterstop that cannot be observed by the naked eye and affecting the subsequent sealing; a wear-resistant layer 8 for improving the wear-resistant effect of the waterstop is fixed to the bottom of the protective layer 6. The material of the wear-resistant layer 8 is set as butyl rubber. By setting the wear-resistant layer 8, the surface of the waterstop can be protected, increasing the surface wear-resistant performance of the waterstop, and during installation and use, the friction of objects will not damage the waterstop; a filling strip 9 and a plurality of joint strips 10 convenient for fixing with concrete are respectively fixed to the top of the waterstop baseband 1. By setting the filling strip 9 and the plurality of joint strips 10, it is convenient for the waterstop to be more stably connected to the concrete and not easy to fall off.

[0022] Working principle: During the construction process, workers first need to splice multiple base waterstop belts 1. Take two adjacent base waterstop belts 1, such that the first splicing block 21 on one side of one base waterstop belt 1 is located above the second splicing block 22 on one side of the other base waterstop belt 1. Use tools to friction-polish the surfaces at the positions below the first splicing block 21 and the second splicing block 22. The worker applies the adhesive glue on the contacting planes of the first splicing block 21 and the second splicing block 22 that are close to each other, and then pushes the corresponding strip 24 into the slot 23. The strip 24 is a rubber convex strip and has a certain elasticity. While the strip 24 is engaged with the slot 23, the sealing strip 26 in the slot 23 is engaged in the sealing groove 25 in the strip 24, making the connection between the first splicing block 21 and the second splicing block 22 more sealed. At this time, the first splicing block 21 and the second splicing block 22 are mutually attached, and the glue on their surfaces is adhesively bonded to each other. Moreover, the strip 24 and the slot 23 play a role in limiting and fixing, so that the positions where the adhesive glue is applied will not separate from each other. At the same time, the reinforcing layer 3 and the reinforcing rib 5 both improve the structural strength of the waterstop belt, making the waterstop belt not easily break. And the reinforcing rib 5 is perpendicular to the joint strip 10, improving the tensile capacity of the waterstop belt and preventing the waterstop belt from being torn when the installed building deforms. The surface of the waterstop belt has a wear-resistant layer 8, improving the friction resistance of the waterstop belt, so that the surface of the waterstop belt will not be damaged when there is friction with an object during installation and use, making its service life longer. During the use of the waterstop belt, workers need to detect and maintain it, and replace it in time when the waterstop belt is damaged or broken. When it is night, workers observe the surface of the waterstop belt. If cracks appear on the surface of the waterstop belt, the fluorescent particles 7 will emit fluorescence. Workers can then replace and maintain the corresponding waterstop belt, making the observation more convenient and preventing the cracks from being too small to be observed by the naked eye of the workers.
