[0034] Please refer to the attached document. Figures 1-7 This application illustrates a water-stopping device for perforated steel plates on the top of a steel grid structure, used for waterproofing projects at the perforation locations of the steel plates. Specifically, it includes: a first sealing element 3, a second sealing element 4, and a connecting strip 5.

[0035] The first sealing element 3 and the second sealing element 4 are joined from both sides to the two sides of the through plate support 2, and are fastened to the outside of the first sealing element 3 and the second sealing element 4 by the connecting strap 5, so that the first sealing element 3 and the second sealing element 4 are tightly clamped to both sides of the through plate support 2 to form a stable seal. This connection method is easy to install and has high reliability after installation.

[0036] Specifically, the first sealing element 3 includes, from the inside to the outside, an inner layer 303, an arc-shaped metal plate 302, and an outer layer 301. The inner layer 303 and the outer layer 301 are both made of rubber. The inner side of the inner layer 303 is provided with a side opening 304 that mates with the side of the through plate support 2. The second sealing element 4 has the same structure as the first sealing element 3.

[0037] After the first sealing element 3 and the second sealing element 4 are installed, the fastening force of the connecting strip 5 presses the outer layer 301, causing the outer layer 301 to deform. This causes the fastening force to be applied stably to the arc-shaped metal plate 302. Then, the arc-shaped metal plate 302 evenly applies the fastening force to the inner layer 303, making the inner layer 303 fit tightly against the side of the through plate support 2, thus forming a good seal.

[0038] The through-plate support 2 is generally made of angle steel or I-beam, depending on the support requirements of the actual equipment installed on the top of the through-plate support 2. The through-plate support 2 shown in the attached figure is an I-beam.

[0039] In one embodiment, to ensure that the bottoms of the first sealing member 3 and the second sealing member 4 can be in close contact with the top surface of the color steel plate 1, a first inclined surface a corresponding to the top surface of the color steel plate 1 is provided at the bottom of both the first sealing member 3 and the second sealing member 4, such as... Figure 2 As shown, after the first seal 3 and the second seal 4 are installed, the bottoms of the first seal 3 and the second seal 4 are tightly attached to the top surface of the color steel plate 1 to form a contact sealing surface.

[0040] In one embodiment, the top of both the first seal 3 and the second seal 4 is provided with a second inclined surface b that slopes outward, so that water falling along the side of the through plate support 2 is diverted down from the second inclined surface b at the top of the first seal 3 and the second seal 4.

[0041] In one embodiment, such as Figure 5 As shown, the arc-shaped metal plate 302 and the outer layer 301 are both arc-shaped, the inner layer 303 is semi-circular, and the arc-shaped metal plate 302 and the inner layer 303 are eccentrically arranged, while the outer layer 301 and the inner layer 303 are concentrically arranged.

[0042] The arc-shaped metal plates corresponding to the first sealing element 3 and the second sealing element 4 are centrally symmetrical. When the arc-shaped metal plates corresponding to the first sealing element 3 and the second sealing element 4 are simultaneously pressed inward, they can be staggered. For example, the end of the arc-shaped metal plate 302 in the first sealing element 3 can be pressed and embedded in the outer and inner layers of the second sealing element 4 to form an interlaced and tightly compressed structure.

[0043] In one embodiment, the side of the arc-shaped metal plate 302 is provided with a mesh opening 305. The first sealing member 3 and the second sealing member 4 are manufactured as a single unit using a mold and a machine. The outer layer 301 and the inner layer 303 are connected as a single unit at the mesh opening 305.

[0044] In one embodiment, the connecting belt 5 includes a toothed belt 501, a guide portion 502 is fixedly provided at the first end of the toothed belt 501, and a connector 503 is fixedly connected to the second end of the toothed belt 501. In use, the first end of the toothed belt 501 is inserted into the connector 503, the connecting belt 5 forms a ring, and the first seal 3 and the second seal 4 are fastened.

[0045] In one embodiment, the connecting strip 5 is made of stainless steel, which is not easily corroded and has a long service life.
