Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, and in particular to a device for preventing leakage in building engineering. Background Technology
[0002] Concrete structures expand and contract with changes in temperature and foundation settlement, forming expansion joints. These expansion joints can leak in various forms and to varying degrees during construction and use. This not only affects the building's appearance and normal functionality, but also causes steel reinforcement corrosion and cement neutralization, thus shortening the building's lifespan and jeopardizing its normal use and structural durability.
[0003] Currently, in the process of dealing with leakage in expansion joints, rigid cement mortar, quick-drying cement, epoxy and other materials are used for sealing. The principle of setting up expansion joints is to meet the needs of building deformation. Rigid sealing will restrict the needs of building deformation. As time goes by, the sealing will soon be torn and deformed, causing damage. Rigid sealing becomes temporary, and leakage will soon reappear.
[0004] Therefore, it is necessary to provide a new anti-seepage treatment device for building engineering to solve the above-mentioned technical problems. Utility Model Content

[0007] Preferably, the two ends of the rubber bladder are semi-circular, its sidewalls are planar, and the thickness of the rubber bladder is greater than the thickness of the deformation joint.
[0008] Preferably, the construction joint has two layers of rubber bladders, one upper and one lower, and the interior of each rubber bladder is hollow. The gap between the two layers of rubber bladders is filled with the sealing filler layer.

[0010] Preferably, the surface of the decorative layer is flush with the surface of the concrete structure, and the thickness of the limiting block is the same as the thickness of the limiting groove.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0021] Please see Figures 1-5 ,in Figure 1 A schematic diagram of a preferred embodiment of the building engineering anti-seepage treatment device provided by this utility model; Figure 2 for Figure 1 The enlarged structural diagram of part A is shown below; Figure 3 for Figure 1 The diagram shows the structural schematic of the positioning structure. Figure 4 for Figure 1 The diagram shows the structure of the rubber bladder. Figure 5 for Figure 1The diagram shows the overall structure of the groove structure. The building engineering anti-seepage treatment device includes: a rubber bladder 1, which is fitted inside the expansion joint between concrete structures 6; a sealing filling layer 2, which fills the interior of the expansion joint; and a groove structure 7, which is located on the surface of the concrete structure 6 at the top of the expansion joint. The groove structure 7 includes a limiting groove 71, an arc-shaped groove 72, and a placement groove 73. The placement groove 73 is located on the surface of the concrete, the arc-shaped groove 72 is located at the opening at the top of the expansion joint, and the limiting groove 71 is located on both sides of the concrete structure at the top of the expansion joint. The structure 6 has the following components: a surface; a waterproof material 3, which is laid inside the placement groove 73; a limiting structure 5, which is laid on the surface of the waterproof material 3; and a positioning structure 4, which is fixed at the center of the bottom surface inside the placement groove 73. The positioning structure 4 includes a positioning plate 41, a fixing nail 42, a spring piece 43, and an elastic filling layer 44. The positioning plate 41 is fixed at the center of the bottom surface inside the placement groove 73 by the fixing nail 42. The spring piece 43 is located at the center of the positioning plate 41, and the elastic filling layer 44 fills the interior of the spring piece 43.
[0022] In the specific implementation process, such as Figure 1 , Figure 2 , Figure 5 As shown, the two ends of the rubber bladder 1 are semi-circular, its sidewalls are flat, and the thickness of the rubber bladder 1 is greater than the thickness of the expansion joint; the construction joint is provided with two layers of the rubber bladder 1, and the inside of the rubber bladder 1 is hollow, and the gap between the two layers of the rubber bladder 1 is filled with the sealing filling layer 2; this allows the rubber bladder 1 to be held in place inside the expansion joint by its own elasticity, thereby enabling the rubber bladder 1 to adapt to the deformation of the concrete structure 6 caused by temperature, and the sealing filling layer can seal the construction joint.
[0023] In the specific implementation process, such as Figure 1 and Figure 2 As shown, the limiting structure 5 includes a decorative layer 51 and a limiting block 52. The limiting block 52 squeezes the waterproof material 3 and engages it inside the limiting groove 71. The decorative layer 51 is laid on the surface of the waterproof material 3. The surface of the decorative layer 51 is flush with the surface of the concrete structure 6, and the thickness of the limiting block 52 is the same as the thickness of the limiting groove 71. This allows the waterproof material 3 to be squeezed and fixed at both ends by the limiting block 52, effectively preventing water from seeping inward from the edge of the waterproof material 3. The decorative layer 51 also helps maintain the integrity of the concrete structure 6.
[0024] In the specific implementation process, such as Figure 1 and Figure 2 As shown, the sidewall of the spring piece 43 is arc-shaped, and the spring piece 43 presses the waterproof material 3 to fit against the inner sidewall of the arc-shaped groove 72; this facilitates the spring piece 43 supporting the waterproof material 3 recessed in the arc-shaped groove 72, thereby sealing the top opening of the deformation joint, and the arc-shaped spring piece 43 can adapt to the deformation of the concrete structure 6.
[0025] The working principle of the building engineering seepage prevention and control device provided by this utility model is as follows:
[0026] In use, firstly, a portion of the sealing filler layer 2 is injected into the bottom of the expansion joint through the top opening, sealing the bottom opening of the expansion joint with the sealing filler layer 2. Then, the rubber bladder 1 is inserted from the top of the expansion joint, so that it abuts against the sealing filler layer 2 pre-filled at the bottom of the expansion joint. Next, another layer of the sealing filler layer 2 is filled into the interior of the expansion joint, fixing the lower rubber bladder 1 between the two layers of the sealing filler layer 2. Then, another layer of the rubber bladder 1 is inserted into the interior, and another layer of the sealing filler layer 2 is filled in here to align and seal and fix it, so that the sealing filler layer 2 can fill the gap in the expansion joint. Then, with the expansion joint as the center, the placement groove 73 is opened on the surface of the concrete structure 6 on both sides of its top, and the arc-shaped groove 72 is opened at the top opening of the expansion joint. The limiting groove 71 is set at the corresponding position inside the placement groove 73. Then, the waterproof material 3 is laid on the bottom surface inside the placement groove 73. Then, the spring piece 43 is placed in the center of the waterproof material 3 through the positioning plate 41, and the arc-shaped sidewall of the spring piece 43 is made to press the waterproof material 3 into the inside of the arc-shaped groove 72. The position of the positioning plate 41 is fixed by the fixing nail 42. Then, the positioning block is made to press the waterproof material 3 into the inside of the limiting groove 71, and the position of the waterproof material 3 is fixed by the limiting block 52 and the positioning plate 41. The waterproof material 3 seals the top opening of the expansion joint to prevent water leakage. This device has the advantages of being able to meet the expansion and contraction deformation caused by factors such as temperature changes and foundation settlement, and can effectively prevent leakage of expansion joints.
[0027] Compared with related technologies, the building engineering seepage prevention and control device provided by this utility model has the following beneficial effects:
[0028] This utility model provides a device for preventing leakage in building engineering. First, the sealing filling layer 2, together with the rubber bladder 1, is filled into the interior of the expansion joint. The sealing filling layer 2 not only seals the gap of the expansion joint, but also independently fixes the rubber bladder 1 in two layers, clamping it inside the expansion joint. This allows the rubber bladder 1 to adapt to the deformation of the concrete structure 6 caused by factors such as temperature changes. Then, the waterproof material 3 is laid in a groove structure 7 on the outer side of the top of the expansion joint of the concrete structure 6, and fixed by the positioning structure 4 and the limiting tube. This seals the top opening of the expansion joint with the waterproof material 3. The decorative layer 51 is poured onto the surface of the waterproof material 3, and the surface of the decorative layer 51 is flush with the surface of the concrete structure 6, which helps to enhance the integrity of the concrete structure 6.
