Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative efforts belong to the range of protection of the utility model.
[0025] Embodiment: please refer to Figures 1-4The external pasting type waterstop structure with active and passive integrated waterstop comprises a waterstop belt body 1, side edge belts 2 fixedly connected to both sides of the top end of the waterstop belt body 1, and a main and passive waterstop structure arranged at the top end of the waterstop belt body 1 for improving the waterstop effect.
[0026] The main and passive waterstop structure comprises waterstop bags 7 fixedly connected to both sides of the top end of the waterstop belt body 1, a first expansion material 10 movably connected to the inside of the waterstop bag 7, and first water permeation holes 8 formed in both sides of the waterstop bag 7 and fixedly connected with the inside of the waterstop bag 7.
[0027] The waterstop bags 7 arranged at both sides of the top end of the waterstop belt body 1 are symmetrically arranged, and the first water permeation holes 8 are connected with the inside of the waterstop bag 7.
[0028] The center line of the waterstop bag 7 is on the same vertical plane as the center line of the waterstop belt body 1, and the first expansion material 10 is movably connected with the waterstop belt body 1.
[0029] Specifically, as shown in Figure 1 , Figure 2 and Figure 4 , a group of waterstop bags 7 are arranged at both sides of one end of the waterstop belt body 1, when the passive waterstop effect of the waterstop sheets 3 arranged at both sides is insufficient and water leakage occurs, the water leaks inward and permeates into the inside of the waterstop bag 7 through the first water permeation holes 8, the first expansion material 10 in the inside of the waterstop bag 7 expands rapidly to deform and enlarge the waterstop bag 7, so as to tightly adhere to the building component, thereby achieving the passive waterstop effect, and realizing the active and passive integrated waterstop to improve the waterstop effect.
[0030] The waterstop belt body 1 is fixedly connected with deformation sheets 12 at both sides of the top end, the deformation sheets 12 are fixedly connected with deformation bags 6 at one side, the deformation bags 6 are provided with second water permeation holes 11 at one side, the second water permeation holes 11 are fixedly connected with water permeation nets 16 in the inside, the top end of the deformation sheet 12 is fixedly connected with an arc-shaped sheet 5, the top end of the waterstop belt body 1 is provided with a groove 13, the other side of the deformation sheet 12 is fixedly connected with a convex strip 14, and the inside of the deformation bag 6 is movably connected with a second expansion material 15.
[0031] The second water permeation holes 11 are connected with the inside of the deformation bag 6, and the center line of the groove 13 is on the same vertical plane as the center line of the waterstop belt body 1.
[0032] The center line of the arc-shaped sheet 5 is on the same vertical plane as the center line of the waterstop belt body 1, and the second expansion material 15 is movably connected with the waterstop belt body 1.
[0033] Specifically, as shown in Figure 1 and Figure 3As shown, after installation, the waterstop strip allows the arc-shaped piece 5 to fit against one end of the building's expansion joint or deformation joint. When water leaks at these joints, the water will seep into the interior of the deformation bag 6 through the second seepage hole 11. The second expansion material 15 inside the deformation bag 6 quickly expands and squeezes the deformation piece 12. The deformation piece 12 automatically squeezes the arc-shaped piece 5 to deform, making it tightly fit against one end of the joint, thereby improving the water-stopping effect at the joint. This achieves the ability to automatically block the joint to improve the water-stopping effect at the joint.
[0034] Two sets of water-blocking plates 3 are fixedly connected to both sides of the top end of the waterstop body 1, and a positioning plate 4 is fixedly connected to the top end of the water-blocking plate 3.
[0035] The centerline of the positioning piece 4 and the centerline of the water-blocking piece 3 are on the same vertical plane, and the centerline of the water-blocking piece 3 and the centerline of the water-stopping strip 1 are on the same vertical plane.
[0036] Specifically, such as Figure 1 As shown, the waterstop strip body 1 has side strips 2 and water-blocking plates 3 on both sides of one end. The side strips 2 and water-blocking plates 3 provide a passive water-stopping effect while being tightly connected to the building components, which can ensure the firmness of the waterstop strip. The positioning plate 4 at one end of the water-blocking plate 3 is also connected to the building components, which can further improve the firmness of the waterstop strip installation and ensure the water-stopping effect, thus improving the firmness of the waterstop strip installation.
[0037] Working Principle: In use, the waterstop 1 has side strips 2 and water-blocking plates 3 on both sides of one end. The side strips 2 and water-blocking plates 3 provide a passive water-stopping effect while being tightly connected to the building components, ensuring the waterstop's stability. Furthermore, the positioning plate 4 at one end of the water-blocking plate 3 is also connected to the building components, further enhancing the waterstop's installation stability and ensuring the water-stopping effect. After installation, the arc-shaped plate 5 fits against one end of the building's expansion joint or deformation joint. When water leaks at these joints, it seeps into the interior of the deformation bag 6 through the second seepage hole 11. The second expansion material 15 inside the deformable bag 6 rapidly expands and squeezes the deformable sheet 12. The deformable sheet 12 deforms and automatically squeezes the arc-shaped sheet 5 to deform, so that it fits tightly against one end of the gap, thereby improving the water-stopping effect at the gap. A set of water-stop bags 7 are respectively set on both sides of one end of the water-stop tape body 1. When the passive water-stopping effect of the water-blocking sheet 3 on both sides is insufficient and water leakage occurs, water leaks inward and seeps into the interior of the water-stop bag 7 through the first seepage hole 8. The first expansion material 10 inside the water-stop bag 7 rapidly expands, causing the water-stop bag 7 to deform and become larger, so that it fits tightly against the building component and achieves a passive water-stopping effect.
