Abstract
Description
Technical Field
[0001] This utility model relates to the field of building engineering technology, specifically a water-stopping device for openings in basement shear walls. Background Technology
[0002] Basements typically require the installation of various pipes and equipment for ventilation, water supply and drainage, electrical systems, and civil defense facilities. These pipes need to pass through shear walls, thus necessitating the pre-reserved or specially designed openings. These openings in the basement shear walls are weak points in waterproofing; under hydrostatic pressure, water can easily seep into the room through the gaps between the openings and the pipes. Common methods to address this issue include sealing with sealant. After the pipes are installed, the gaps between the pipes and the openings are filled with waterproof sealant or grouted. However, due to the often poor precision in the size and shape of the openings, complete filling is difficult, and grouting can easily create cavities, allowing moisture to easily seep into the gaps through the wall at the opening. Summary of the Invention
[0003] The purpose of this utility model is to provide a water-stopping device for the opening of a basement shear wall, so as to solve the problems existing in the prior art.
[0004] To achieve the above objectives, the present invention provides a water-stopping device for a basement shear wall opening, comprising a first water-stopping pipe and a second water-stopping pipe; the first water-stopping pipe includes an inner pipe and a first sealing ring plate, the first sealing ring plate being disposed on one side of the inner pipe and extending outward, and a first water-stopping ring plate also being disposed on the outer side of the inner pipe; the second water-stopping pipe includes an outer pipe and a second sealing ring plate, the second sealing ring plate being disposed on one side of the outer pipe and extending inward and outward from the outer pipe, and a second water-stopping ring plate also being disposed on the inner side of the outer pipe.
[0005] Furthermore, the inner and outer tubes have the same wall thickness, and the gap between the inner tube and the first water-stop ring plate, and between the outer tube and the second water-stop ring plate, is slightly larger than the wall thickness; the outer diameter of the inner tube is the same as the inner diameter of the outer tube.
[0006] Furthermore, a water-stop strip is provided in the gap between the inner tube and the first water-stop ring plate, and between the outer tube and the second water-stop ring plate. A water-stop strip is wrapped around the outer tube, and annular water-stop rings are provided inside the first sealing ring plate and the second sealing ring plate.
[0007] Furthermore, an installation sleeve is also covered on the outside of the outer tube. The installation sleeve 3 is a barrel-shaped structure with openings at both ends, and one side is attached to the second sealing ring plate of the second waterstop pipe.
[0008] Furthermore, the water-stopping device also includes an installation tool, which includes a crossbar, a first pressure plate, and a second pressure plate. The crossbar has a threaded portion on one side and a crossbar on the other end. The first pressure plate has a long slot on one side of its length, and the second pressure plate has a through hole in the center. The crossbar passes through the slot of the first pressure plate and the through hole in the center of the second pressure plate, and a nut is provided on the threaded portion.
[0009] Furthermore, a raised water-blocking ring is provided in the middle of the first sealing ring plate and the second sealing ring plate, and several raised extrusion strips are provided on the inner side of the first sealing ring plate and the second sealing ring plate.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] As attached Figure 1-4As shown, the water-stopping device for the basement shear wall opening involved in this utility model includes a first water-stopping pipe 1 and a second water-stopping pipe 2; the first water-stopping pipe 1 includes an inner pipe 11 and a first sealing ring plate 12, the first sealing ring plate 12 is disposed on one side of the inner pipe and extends outward, and a first water-stopping ring plate 13 is also disposed on the outside of the inner pipe 11. A gap is provided between the inner pipe 11 and the first water-stopping ring plate 13.
[0018] The second water-stopping pipe 2 includes an outer pipe 21 and a second sealing ring plate 22. The second sealing ring plate 22 is disposed on one side of the outer pipe and extends inward and outward from the outer pipe 21. A second water-stopping ring plate 23 is also disposed on the inner side of the outer pipe 21. A gap is provided between the outer pipe 21 and the second water-stopping ring plate 23.
[0019] The inner tube 11 and the outer tube 21 have the same wall thickness. The gap between the inner tube 11 and the first water-stop ring plate 13, and between the outer tube 21 and the second water-stop ring plate 23, is slightly larger than the wall thickness, about 0.5 cm, to accommodate the water-stop strip. The outer diameter of the inner tube 11 is the same as the inner diameter of the outer tube 21.
[0020] In use, the first waterstop pipe 1 and the second waterstop pipe 2 are inserted relative to each other. The end of the outer pipe 21 is inserted into the gap between the inner pipe 11 and the first waterstop ring plate 13, and the inner pipe 11 is inserted into the gap between the outer pipe 21 and the second waterstop ring plate 23. The first sealing ring plate 12 and the second sealing ring plate 22 are fixed to both sides of the wall. In the attached diagram, the first sealing ring plate 12 and the second sealing ring plate 22 are fixed with bolts. During on-site construction, the lengths of the inner pipe 11 and the outer pipe 21 can be cut according to the thickness of the wall.
[0021] To further improve the sealing effect, a water-stop strip is provided in the gap between the inner pipe 11 and the first water-stop ring plate 13, and between the outer pipe 21 and the second water-stop ring plate 23. A water-stop strip z is wrapped around the outer pipe 21, and annular water-stop rings are provided inside the first sealing ring plate 12 and the second sealing ring plate 22. The aforementioned water-stop strip and water-stop ring are commercially available products. In one embodiment of the applicant's work, a water-swellable water-stop strip is wrapped around the outer side of the outer pipe. By adjusting the thickness of the water-stop strip, due to its large deformation adaptability, good contact and sealing effect between it and the opening can be ensured.
[0022] As attached Figure 1 As shown in Figure 3, to facilitate installation, an installation sleeve 3 is also covered on the outside of the outer pipe 21. This reduces the amount of dust and sand falling from the wall surface into the space between the inner pipe 11 and the outer pipe 21 during installation. The installation sleeve 3 is a barrel-shaped structure with open ends made of plastic film. One side is pasted onto the second sealing ring plate 22 of the second waterstop pipe 2. It is compressed and fitted onto the outside of the outer pipe at the factory. During installation, the installation sleeve 3 is pulled open, the second waterstop pipe 2 is passed through the entire opening, and then the first waterstop pipe 1 is inserted into the installation sleeve 3 to cooperate with the second waterstop pipe 2.
[0023] This application also includes an installation tool 4 for use with the above-mentioned water-stopping device, the installation tool 4 including a crossbar 41, a first pressure plate 42, and a second pressure plate 43.
[0024] The crossbar 41 has a threaded portion on one side and a crossbar at the other end. The first pressure plate 42 has an elongated slot 421 on one side of its length, and the second pressure plate 43 has a through hole in its center. The crossbar 41 passes through the slot 421 of the first pressure plate 42 and the through hole in the center of the second pressure plate 43. A nut is provided on the threaded portion. In use, the first pressure plate 42 is tilted (the presence of the elongated slot 421 allows the first pressure plate 42 to tilt, and its tilt angle is related to the length of the elongated slot 421). After passing through the opening, the first pressure plate 42 becomes vertical under the action of gravity and is then locked with the nut. The first pressure plate 42 and the second pressure plate 43 compress the first sealing ring plate 12 and the second sealing ring plate 22, thereby achieving the nesting of the two water-stopping pipes through compression. By installing the aforementioned water-stopping device, a through-pipe with a regular shape and high surface dimensional accuracy can be formed at the wall opening. It can also effectively prevent leakage between the wall and the water-stopping pipe, facilitating the subsequent installation of related pipes and sealing operations.
[0025] As attached Figure 4 As shown, further, in order to reduce the flow of water from the wall surface into the inner pipe 11 through the first sealing ring plate 12 and the second sealing ring plate 22, a raised water-blocking ring d is provided in the middle of the first sealing ring plate 12 and the second sealing ring plate 22, and the top of the water-blocking ring d is provided with an outward protrusion.
[0026] Furthermore, to improve the sealing effect of the first sealing ring plate 12 and the second sealing ring plate 22, several raised extrusion strips t are provided on the inner side of the first sealing ring plate 12 and the second sealing ring plate 22 to improve the tightness of the connection with the water-stop ring when fastened to the wall.
[0027] To prevent the first pressure plate 42 and the second pressure plate 43 from crushing the water-retaining ring d, the installation tool 4 also includes a pressure ring 44, which is circular in shape and has an inner diameter larger than the outer diameter of the water-retaining ring d. In use, it is placed outside the water-retaining ring, and its thickness is greater than the height of the water-retaining ring d. The pressure ring 44 has grooves to avoid affecting the tightening of the bolts on the first sealing ring plate 12 and the second sealing ring plate 22.
[0028] It should be noted that, unless otherwise explicitly specified and limited, terms such as "installation," "connection," "joining," "fixing," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
