Description

Technical Field

[0001] The utility model relates to the technical field of waterstops, in particular to a rubber waterstop. Background Art

[0002] Rubber waterstop is a waterstop product made by utilizing the flexible and elastic properties of rubber materials when subjected to stress. It can form a waterstop effect as the expansion joint moves, ensuring a sealing and waterproof effect.

[0003] However, most rubber waterstops on the market primarily utilize grooves on their surfaces to enhance the stability of their connection to the concrete base. For example, in the rubber waterstop patented CN215977794U, ridges are affixed to the base strip on either side of the deformation hole to enhance the connection strength between the waterstop and the concrete. Alternatively, in the rubber waterstop patented CN220118137U, several wavy reinforcement strips are affixed to either side of the base strip to increase the contact area with the concrete and enhance the connection.

[0004] However, when the deformation joint shifts, the rubber structure experiences stress deformation. Due to the different material properties of the rubber and concrete, simply using rubber ridges or reinforcement strips integrally molded with the rubber will still result in insufficient connection strength between the rubber and concrete. The joint between the two structures is prone to separation, causing the deformation hole in the middle of the rubber to deviate from the deformation joint, affecting the sealing and reducing the water-stopping effect. Therefore, a rubber waterstop is urgently needed to solve the above problem. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0028] Reference Figure 1-Figure 2 The utility model provides a rubber waterstop, comprising:

[0029] The rubber body 1 is a double-layer vulcanized structure. The upper layer of the rubber body 1 is symmetrically provided with a water retaining portion along the center, and the lower layer of the rubber body 1 is symmetrically provided with a barb portion along the center.

[0030] The support body 2 is wrapped in the rubber body 1. The support body 2 is provided with at least two support ends, and the two support ends are respectively wrapped in the water retaining portion and the barb portion.

[0031] There are a plurality of support bodies 2 , which are arranged at equal intervals along the length direction of the rubber body 1 .

[0032] The utility model prepares a rubber body 1 through a vulcanizer, and divides the rubber body 1 into an upper and lower double-layer structure, forms a water retaining portion by integral vulcanization on the upper layer of the rubber body 1, and forms a barb portion by integral vulcanization on the lower layer of the rubber body 1, and in addition, fills a support body 2 in the rubber body 1, utilizes the characteristic that the structural strength of the support body 2 is greater than that of the rubber body 1, and provides the support body 2 with a plurality of support ends, and respectively fills the water retaining portion and the barb portion through the support ends, thereby ensuring the structural strength of the rubber body 1, and at the same time, enhancing the fixing stability of the rubber body 1 and the concrete under the action of the barb portion.

[0033] Moreover, in the present technical solution, multiple support bodies 2 are spaced apart along the length direction of the rubber body 1, and the structural strength is greater than that of the rubber body 1. On the basis of improving the strength of the rubber body 1, the deformation effect of the rubber body 1 can also be guaranteed. Therefore, when the deformation joint produces stress displacement, the overall rubber waterstop structure can undergo adaptive deformation to ensure the water-stopping effect.

[0034] Furthermore, the water retaining part includes:

[0035] At least one pair of first connectors are integrally formed on the top surface of the rubber body 1 symmetrically along the center, and a first protrusion 101 is provided on the top of the first connector.

[0036] By integrally molding the first connector with the rubber body 1 and symmetrically arranging at least one pair along the center of the rubber body 1, the first protrusion 101 extending from the first connector relative to the rubber body 1 is utilized to provide a water-blocking effect for the top of the rubber body 1, thereby forming the water-blocking structure proposed in this patent.

[0037] Furthermore, the barb portion includes:

[0038] At least one pair of second connectors are integrally formed on the bottom surface of the rubber body 1 symmetrically along the center, and a second protrusion 102 is formed on the bottom of the second connector.

[0039] Similarly, a pair of second connectors are symmetrically fixed to the bottom surface of the rubber body 1, and a second protrusion 102 is extended along the bottom surface of the rubber body 1 to form the barb structure in this patent to enhance the fixing stability of the rubber body 1 and the concrete.

[0040] Furthermore, it also includes:

[0041] A pair of third connectors are integrally formed on both sides of the rubber body 1 . The outer ends of the third connectors are provided with third protrusions 103 , which are arranged perpendicular to the large surface of the rubber body 1 .

[0042] In addition, a third connector is also arranged in this technical solution, and a third protrusion 103 is extended from the third connector relative to the rubber body 1 to form a reinforcing rib structure that can act on the rubber body 1, thereby improving the structural strength of the rubber body 1 and reducing the possibility of damage to the rubber body 1.

[0043] Furthermore, the support body 2 is a plate-molded block structure, the rubber body 1 is wrapped around the support body 2 , and the support body 2 and the rubber body 1 are fixedly bonded by vulcanization.

[0044] Furthermore, the first protrusion 101 is a T-shaped structure.

[0045] Furthermore, the second protrusion 102 is a V-shaped structure.

[0046] It can be understood that the structural shape of the first protrusion 101 and the second protrusion 102 in the present technical solution is not limited to the above-mentioned form. Both can adopt a T-shaped or V-shaped structure. It is only necessary to ensure that the support body 2 can be filled in the first protrusion 101 and the second protrusion 102 to effectively improve the connection strength between the overall rubber water stop and the concrete.

[0047] Furthermore, the support body 2 is formed by processing a stainless steel plate.

[0048] The structural strength of the support body 2 is greater than that of the rubber body 1. By filling the support body 2 in the rubber body 1 and extending a T-shaped plate-like support structure corresponding to the first protrusion 101 and a V-shaped plate-like support structure corresponding to the second protrusion 102, the structural strength of the rubber body 1 is improved, and at the same time, the water-retaining effect and the connection stability between the rubber body 1 and the concrete are improved.

[0049] In another embodiment of the present technical solution, the support body 2 extends a plate-shaped support structure, which serves as a support structure for the third protrusion 103. By filling the extended end of the support body 2 into the third protrusion 103, the strength of the formed reinforcing rib structure can be further improved.

[0050] The method of using the rubber waterstop of the utility model is as follows:

[0051] The through hole 104 integrally formed in the center of the rubber body 1 corresponds to the position of the expansion joint, and one side of the bottom surface of the rubber body 1 is fitted with the concrete base, and the barbed portion of the lower layer of this side is buried in the concrete. Utilizing the structural characteristics of the rubber body 1 that swells when exposed to water, the gap in the concrete joint is filled to form a sealing and water-stopping effect. Then repeat the above steps on the other side of the rubber body 1, and finally make the rubber body 1 horizontally distributed, and the two barbed portions are relatively arranged and respectively connected to the concrete base. Then by pouring concrete on both sides of the top surface of the rubber body 1, the water retaining portion and the third protrusion 103 are anchored and connected with the concrete to complete the installation of the rubber waterstop.
