Description

Technical Field

[0001] This utility model relates to the technical field of steel-edged rubber waterstops, and in particular to an anti-aging steel-edged rubber waterstop. Background Technology

[0002] Steel-edged rubber waterstops are waterproof materials made of high-quality rubber and galvanized steel edges through a special vulcanization process. The structure consists of a rubber body and galvanized steel strips on both sides. The rubber portion typically uses aging-resistant rubber materials such as natural rubber, neoprene rubber, or nitrile rubber, while the steel edges are formed through a special vulcanization process. It usually appears as a rubber strip with steel edges, and its length can be customized to meet specific needs, generally ranging from one to several meters.

[0003] Steel-edged rubber waterstops typically use rectangular steel strips. One side of the steel strip is vulcanized with the rubber waterstop body, while the other side overlaps with the concrete. However, during the vulcanization process, the adhesion between the steel strip and the rubber waterstop is weak, resulting in an unstable connection. This makes them prone to detachment during construction. Furthermore, typical steel-edged rubber waterstops often have sharp angles or bends, where significant stress can cause breakage. Therefore, ensuring a secure connection between the steel strip and the rubber waterstop, and avoiding sharp angles, are crucial design challenges for anti-aging steel-edged rubber waterstops. Utility Model Content

[0004] This utility model provides an anti-aging steel-edged rubber waterstop to address the issues of insufficient connection between the steel strip and the rubber waterstop, as well as the presence of certain bends and turns on the steel-edged rubber waterstop.

[0005] This utility model solves the above-mentioned technical problems through the following technical solutions:

[0006] This utility model provides an anti-aging steel-edged rubber waterstop, including a rubber waterstop and further comprising:

[0007] A steel-edged structure is provided on both sides of the rubber waterstop.

[0008] The first protrusion is provided on the upper and lower sides of the rubber waterstop, and the first protrusion increases the contact area of ​​the rubber waterstop.

[0009] Preferably, the sidewalls of the rubber waterstop at the middle and both ends are arc-shaped and expand outwards, and the turning points of the expanded parts of the rubber waterstop are arc-shaped transitions.

[0010] In this technical solution, the enlarged sidewalls at the middle and both ends of the rubber waterstop can increase the contact area with concrete. At the same time, the transition at the turning point is made by a rounded arc, which can better avoid the existence of sharp corners, which would cause greater stress at the turning point and make the rubber waterstop prone to breakage.

[0011] Preferably, a deformation groove is formed in the side wall of the enlarged middle section of the rubber waterstop, and the cross-section of the deformation groove is elliptical.

[0012] In this technical solution, a deformation groove is provided in the middle of the rubber waterstop, which allows the rubber waterstop to be stretched and shortened within a certain range, thereby improving the elongation of the rubber waterstop and making the rubber waterstop better adaptable to concrete.

[0013] Preferably, the positions of the protrusions fixed on the upper and lower sides of the rubber waterstop are corresponding to each other, the protrusions are distributed on both sides of the deformation groove, the top of the protrusion is set in a pointed shape, and the sidewalls on both sides of the protrusion are provided with grooves.

[0014] In this technical solution, the setting of protrusion one also increases the contact area between the rubber waterstop and the concrete. At the same time, the grooves opened on both sides of protrusion one can further make protrusion one tightly connected.

[0015] Preferably, the rubber waterstop is composed of a rubber substrate, a thermal insulation layer and a waterproof layer. The thermal insulation layer is fixedly installed on the upper and lower sidewalls of the rubber substrate, and the waterproof layer is fixedly installed on the upper and lower sidewalls of the thermal insulation layer.

[0016] Preferably, the insulation layer is made of glass wool.

[0017] In this technical solution, glass wool is made of glass fiber, which has good heat insulation and fire resistance, good weather resistance and is not easy to age. The insulation layer is made of glass wool, which can reduce the impact of external temperature on the internal rubber matrix and reduce the possibility of rubber matrix aging.

[0018] Preferably, the waterproof layer is made of polyvinyl chloride waterproof membrane.

[0019] In this technical solution, the polyvinyl chloride (PVC) waterproof membrane is made from PVC resin and other raw materials, possessing excellent chemical resistance, aging resistance, and weather resistance. It maintains stable performance in various environments, is easy to construct, maintain and repair, and is relatively inexpensive. Therefore, PVC waterproof membrane is an economical and practical waterproof material with strong durability. Using PVC waterproof membrane for the waterproof layer provides effective waterproofing, reduces the impact of external humidity on the internal rubber matrix, and further minimizes the possibility of rubber matrix aging.

[0020] Preferably, the steel edge structure includes a steel strip, positioning holes, and connectors. Positioning holes are provided at equal intervals on the side wall of the steel strip. A connector is fixedly connected to one side of the steel strip. The connector is fixedly installed inside the side wall of the enlarged end of the rubber waterstop.

[0021] Preferably, the sidewall of the connector near the steel strip has an arc-shaped groove, the sidewall of the connector away from the steel strip has a spherical groove, and the upper and lower sidewalls of the connector have two grooves.

[0022] In this technical solution, the first connector is provided with a spherical groove that connects spherically with the side wall of the rubber waterstop, which can effectively prevent the connector from detaching from the rubber waterstop. The arc-shaped groove on the first connector can generate greater resistance when the connector moves outward, thereby further preventing the connector from detaching from the rubber waterstop. The second grooves on the upper and lower sides of the connector cooperate with the side wall of the rubber waterstop. The side wall of the rubber waterstop extending into the second groove will generate greater movement resistance, thereby again preventing the connector from detaching from the rubber waterstop. This ensures a firm connection between the steel strip and the rubber waterstop, effectively preventing the steel strip from detaching from the rubber waterstop during construction.

[0023] Preferably, two protrusions are fixedly connected at equal intervals on the sidewalls of the upper and lower sides of the steel strip, and the two protrusions are in the form of an ">" shape.

[0024] In this technical solution, the two protrusions fixedly connected to the side walls on both the upper and lower sides of the steel strip can increase the contact area between the steel strip and the concrete, thereby making the connection between the steel strip and the concrete firm.

[0025] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0026] The positive and progressive effects of this utility model are as follows:

[0027] 1. By using a rounded transition at the turning point, it is easier to avoid sharp angles at the bend, which would cause greater stress at the bend and make the rubber waterstop more prone to breakage.

[0028] 2. The spherical groove on connector one connects spherically with the side wall of the rubber waterstop, effectively preventing the connector from detaching from the rubber waterstop. The arc-shaped groove on connector one generates significant resistance when the connector moves outward, further preventing the connector from detaching from the rubber waterstop. The grooves on the upper and lower sides of connector two cooperate with the side wall of the rubber waterstop, and the side wall of the rubber waterstop extending into the groove two generates further significant movement resistance, thus again preventing the connector from detaching from the rubber waterstop. This ensures a firm connection between the steel strip and the rubber waterstop, effectively preventing the steel strip from detaching from the rubber waterstop during construction.

[0029] 3. By setting an insulation layer and a waterproof layer on the outside of the rubber matrix, the influence of temperature and humidity on the rubber matrix is ​​reduced, which facilitates a better improvement in the overall anti-aging effect of the rubber waterstop.

[0036] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments described herein.

[0037] like Figure 1-4 As shown, an anti-aging steel-edged rubber waterstop includes a rubber waterstop 1, and further includes:

[0038] Steel edge structure 5, wherein the steel edge structure 5 is disposed on both sides of the rubber waterstop 1;

[0039] The first protrusion 3 is provided on the upper and lower sides of the rubber waterstop 1, and the first protrusion 3 increases the contact area of ​​the rubber waterstop 1.

[0040] The sidewalls of the middle and both ends of the rubber waterstop 1 are arc-shaped and expand outwards, and the turning points of the expanded parts of the rubber waterstop 1 are arc-shaped transitions.

[0041] The enlarged sidewalls at the middle and both ends of the rubber waterstop 1 increase the contact area with concrete. At the same time, the rounded transition at the turning points can better avoid sharp angles that would cause greater stress at the turning points, making the rubber waterstop 1 prone to breakage.

[0042] A deformation groove 2 is provided in the side wall of the enlarged middle part of the rubber waterstop 1, and the cross-section of the deformation groove 2 is elliptical.

[0043] The rubber waterstop 1 has a deformation groove 2 in the middle, which allows the rubber waterstop 1 to be stretched and shortened within a certain range, thereby improving the elongation of the rubber waterstop 1 and making the rubber waterstop 1 better adaptable to concrete.

[0044] The positions of the protrusions 3 fixed on the upper and lower sides of the rubber waterstop 1 correspond to each other. The protrusions 3 are distributed on both sides of the deformation groove 2. The top of the protrusions 3 is set in a pointed shape. The side walls on both sides of the protrusions 3 are provided with grooves 4.

[0045] The addition of protrusion 3 increases the contact area between the rubber waterstop 1 and the concrete. At the same time, the grooves on both sides of protrusion 3 can further ensure that protrusion 3 is tightly connected.

[0046] The rubber waterstop 1 is composed of a rubber substrate 101, a thermal insulation layer 102 and a waterproof layer 103. The thermal insulation layer 102 is fixedly installed on the upper and lower side walls of the rubber substrate 101, and the waterproof layer 103 is fixedly installed on the upper and lower side walls of the thermal insulation layer 102.

[0047] The insulation layer 102 is made of glass wool.

[0048] Glass wool is made of glass fiber, which has good heat insulation and fire resistance, good weather resistance and is not easy to age. The insulation layer 102 is made of glass wool, which can reduce the impact of external temperature on the internal rubber matrix 101 and reduce the possibility of aging of the rubber matrix 101.

[0049] The waterproof layer 103 is made of polyvinyl chloride waterproof membrane.

[0050] Polyvinyl chloride (PVC) waterproof membrane is made from PVC resin and other raw materials, possessing excellent chemical resistance, aging resistance, and weather resistance. It maintains stable performance in various environments, is easy to install, maintain and repair, and is relatively inexpensive. Therefore, PVC waterproof membrane is an economical and practical waterproof material with strong durability. The waterproof layer 103, made of PVC waterproof membrane, provides effective waterproofing, reduces the impact of external humidity on the internal rubber matrix 101, and further minimizes the possibility of aging of the rubber matrix 101.

[0051] The steel edge structure 5 includes a steel strip 501, positioning holes 502 and connectors 503. Positioning holes 502 are provided at equal intervals on the side wall of the steel strip 501. Connector 503 is fixedly connected to one side of the steel strip 501. Connector 503 is fixedly installed in the side wall of the enlarged end of the rubber waterstop 1.

[0052] An arc-shaped groove is provided on the side wall of the connector 503 near the steel strip 501, a spherical groove 511 is provided on the side wall of the connector 503 away from the steel strip 501, and grooves 513 are provided on the upper and lower side walls of the connector 503.

[0053] The connector 503 has a spherical groove 511 that connects spherically with the side wall of the rubber waterstop 1, which effectively prevents the connector 503 from detaching from the rubber waterstop 1. The arc-shaped groove on the connector 503 generates significant resistance when the connector 503 moves outward, further preventing the connector 503 from detaching from the rubber waterstop 1. The grooves 513 on the upper and lower sides of the connector 503 cooperate with the side wall of the rubber waterstop 1. The side wall of the rubber waterstop 1 extending into the groove 513 generates significant movement resistance, further preventing the connector 503 from detaching from the rubber waterstop 1. This ensures a firm connection between the steel strip 501 and the rubber waterstop 1, effectively preventing the steel strip 501 from detaching from the rubber waterstop 1 during construction.

[0054] The steel strip 501 has two protrusions 6 fixedly connected at equal intervals on the side walls on both the upper and lower sides. The two protrusions 6 have an “>” shaped structure.

[0055] The protrusions 6 fixedly connected to the upper and lower side walls of the steel strip 501 can increase the contact area between the steel strip 501 and the concrete, thereby making the steel strip 501 firmly connected to the concrete.

[0056] In use, the rubber waterstop 1 has a deformation groove 2 in the middle, which allows the rubber waterstop 1 to be stretched and shortened within a certain range, improving the elongation of the rubber waterstop 1 and making the rubber waterstop 1 better adapt to concrete. The enlarged sidewalls at the middle and both ends of the rubber waterstop 1 can increase the contact area with concrete. At the same time, the transition at the turning point is made by a rounded arc, which can better avoid the existence of sharp corners, which would cause greater stress at the turning point and make the rubber waterstop 1 prone to breakage. The setting of the protrusion 3 also increases the contact area between the rubber waterstop 1 and the concrete. At the same time, the grooves opened on both sides of the protrusion 3 can further make the protrusion 3 tightly connected.

[0057] The connector 503 is provided with a spherical groove 511 that connects spherically with the side wall of the rubber waterstop 1, which can effectively prevent the connector 503 from detaching from the rubber waterstop 1. The arc-shaped groove on the connector 503 provides greater resistance when the connector 503 moves outward, thereby further preventing the connector 503 from detaching from the rubber waterstop 1. The grooves 513 on the upper and lower sides of the connector 503 cooperate with the side wall of the rubber waterstop 1. The side wall of the rubber waterstop 1 that extends into the groove 513 will generate greater resistance to movement, thereby again preventing the connector 503 from detaching from the rubber waterstop 1. This makes the connection between the steel strip 501 and the rubber waterstop 1 firm and effectively prevents the steel strip 501 from detaching from the rubber waterstop 1 during construction.

[0058] The protrusions 6 fixedly connected to the upper and lower side walls of the steel strip 501 can increase the contact area between the steel strip 501 and the concrete, thus making the connection between the steel strip 501 and the concrete firm. The glass wool is made of glass fiber, which has good heat insulation and fire resistance, good weather resistance and is not easy to age. The insulation layer 102 is made of glass wool, which can reduce the impact of external temperature on the internal rubber matrix 101 and reduce the possibility of aging of the rubber matrix 101. The polyvinyl chloride waterproof membrane is made of polyvinyl chloride resin and other raw materials, which has excellent chemical resistance, aging resistance and weather resistance. It can maintain stable performance in various environments. The waterproof layer 103 is made of polyvinyl chloride waterproof membrane, which can effectively waterproof and reduce the impact of external humidity on the internal rubber matrix 101, further reducing the possibility of aging of the rubber matrix 101, thereby improving the overall anti-aging effect of the rubber waterstop 1.
