Description

Technical Field

[0001] This utility model relates to the field of waterproof sleeves, and in particular to a flexible waterproof sleeve device for through-wall applications. Background Technology

[0002] Cast-in-place concrete structures are widely used in current construction industry design as the mainstream approach. However, to comprehensively consider the functional requirements of buildings, pipes and pipelines often pass through areas such as basement exterior walls and retaining walls at the junction of the main building and basement roof slabs during design and construction. Currently, the main approach for pipes or pipelines passing through basement exterior walls and retaining walls at the junction of the main building and basement roof slabs is to pre-embed flexible waterproof sleeves during the main structure construction. When constructing the integrated pipelines (line) in the basement, the pipes (line) pass through the pre-embedded flexible waterproof sleeves, are adjusted to the center of the sleeves, and then filled with asphalt-impregnated hemp fibers. After filling, the ends of the flexible waterproof sleeves are sealed with sealant. However, because the inner wall of the flexible waterproof sleeve has a smooth surface, directly filling with asphalt-impregnated hemp fibers cannot effectively guarantee the bonding between the asphalt-impregnated hemp fibers and the inner wall of the flexible waterproof sleeve, resulting in poor sealing performance. This poses a risk of capillary water seeping into the gaps at the junction of the asphalt-impregnated hemp fibers and the inner wall of the flexible waterproof sleeve, affecting the subsequent construction and functionality of the building.

[0003] Therefore, it is necessary to provide a flexible waterproof sleeve device for through-wall construction to solve the above-mentioned technical problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a flexible waterproof sleeve device for wall penetration.

[0005] This utility model provides a flexible waterproof sleeve device for wall penetration, comprising: a steel circular steel pipe, a steel water-stop ring, asphalt hemp fibers, a rubber water-stop ring, and a metal plug. The steel circular steel pipe is welded and fixed at both ends and the middle position on the outer side. When the wall penetration pipeline passes through the steel circular steel pipe, the asphalt hemp fibers fill the gap between the steel circular steel pipe and the wall penetration pipeline. A rubber water-stop ring is installed inside the steel circular pipe at the end of the asphalt hemp fiber, and a metal plug is installed at the end of the steel circular pipe. When the through-wall pipeline passes through the metal plug, the asphalt hemp fiber fills the gap between the metal plug and the through-wall pipeline.

[0006] Preferably, the inner wall of the circular steel pipe is provided with annular threads, and the spacing of the annular threads is uniform.

[0007] Preferably, the metal plug comprises a circular steel plate, a hollow steel cylindrical tube, an L-shaped fastener, and asphalt sealant. A circular steel plate is welded to the outer side of one end of the hollow steel cylindrical tube. A circular hole is provided at the center of the circular steel plate, through which the wall-penetrating pipeline can pass. The other end of the hollow steel cylindrical tube is embedded within the circular steel tube, and the end of the hollow steel cylindrical tube contacts a rubber water-stop ring. The center of the hollow steel cylindrical tube coincides with the center of the circular steel plate. The inner wall of the hollow steel cylindrical tube coincides with the inner wall of the circular hole provided at the center of the circular steel plate.

[0008] Preferably, the hollow cylindrical steel tube has an integrally formed L-shaped fastener at one end of the circular steel tube. The inner wall of the circular steel tube has an opening that engages with the L-shaped fastener. The L-shaped fastener corresponds to the opening at the end of the circular steel tube. When pressed inward until the L-shaped fastener extends into the opening, it is rotated to the left, and the L-shaped fastener and the opening at the end of the circular steel tube engage with each other.

[0009] Preferably, the upper part of the metal plug, made of steel circular plate, is coated with asphalt mastic at the joint between the asphalt hemp fiber and the wall-penetrating pipe for secondary sealing.

[0010] The operating procedure (principle) of a through-wall flexible waterproof sleeve device is as follows: 1. Weld the steel water-stop rings to both ends and the middle of the steel circular pipe. The welds should be full and uniform, without slag inclusions or air bubbles. 2. The through-wall pipe passes through a steel circular pipe and is positioned at the center of the steel circular pipe; asphalt hemp fibers are filled into the steel circular pipe. When filling the asphalt hemp fibers, an object is used to compress the asphalt hemp fibers to ensure that the asphalt hemp fibers are in full contact with the threads on the inner wall of the steel circular pipe, thus sealing the gaps at the contact surface. 3. After the asphalt-fiber filling is completed, place the rubber waterstop ring on the outside of the asphalt-fiber; 4. The metal plug is made of a steel circular plate, a steel hollow cylindrical tube, and an L-shaped fastener, which are welded together. The steel hollow cylindrical tube is welded to the surface of the steel circular plate, and the center of the steel hollow cylindrical tube coincides with the center of the steel circular plate. The inner wall of the steel hollow cylindrical tube coincides with the inner wall of the circular hole set at the center of the steel circular plate. 5. Weld the L-shaped fastener to the outer wall of the hollow steel cylinder, with the top flush with the lower surface of the circular steel plate; 6. After the metal plug passes through the central circular hole of the wall-penetrating pipe, insert the hollow steel cylindrical steel pipe into the steel circular steel pipe until the end of the hollow steel cylindrical steel pipe reaches the rubber water-stop ring. Press inward until the L-shaped fastener extends into the opening at the end of the steel circular steel pipe. Rotate to the left, and the L-shaped fastener and the opening at the end of the steel circular steel pipe will interlock. 7. Fill the central circular hole of the metal plug with asphalt-impregnated hemp fibers and the area where the pipe passes through the wall. Apply asphalt sealant to the joint between the steel circular plate on the upper part of the metal plug, the asphalt-impregnated hemp fibers, and the pipe passing through the wall for secondary sealing.

[0011] Compared with related technologies, the present invention provides the following beneficial effects: With its compact structure and easy operation, it can solve the problems of poor bonding and sealing performance between the smooth inner wall of the flexible waterproof sleeve and the asphalt hemp fiber in cast-in-place concrete structures, and reduce the risk of capillary water seeping into the gaps at the joint between the asphalt hemp fiber and the inner wall of the flexible waterproof sleeve in the later stage.

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0015] Please refer to the following: Figures 1 to 3 A flexible waterproof sleeve device for wall penetration has the following structural components: the device mainly includes a steel circular steel pipe 1, a steel water-stop ring 2, asphalt hemp fiber 3, a rubber water-stop ring 4, and a metal plug 5.

[0016] Steel water-stop rings 2 are fixed to both ends and the middle of the outer side of the steel circular pipe 1 by welding. This design can effectively prevent water from seeping in from the gap between the steel pipe and the wall. After the through-wall pipe passes through the steel circular pipe 1, asphalt hemp fiber 3 is filled into the gap between the steel circular pipe 1 and the through-wall pipe to play a preliminary role in waterproofing and sealing.

[0017] Inside the circular steel pipe 1, a rubber water-stop ring 4 is installed at the end of the asphalt-impregnated hemp fiber 3 to further enhance the waterproof effect. Simultaneously, a metal plug 5 is installed at the end of the circular steel pipe 1. When the through-wall pipe passes through the metal plug 5, the gap between the metal plug 5 and the through-wall pipe is also filled with asphalt-impregnated hemp fiber 3 to ensure the gap is sealed.

[0018] Preferably, the inner wall of the steel circular pipe 1 is provided with annular threads, and the spacing of the annular threads is uniform. This design helps to enhance the stability of the connection between the steel pipe and other components.

[0019] Furthermore, the metal plug 5 is composed of a steel circular plate 5-1, a steel hollow cylindrical tube 5-2, an L-shaped fastener 5-3, and asphalt sealant 6. The steel circular plate 5-1 is welded and fixed to the outer side of one end of the steel hollow cylindrical tube 5-2, and a circular hole is provided at the center of the steel circular plate 5-1, through which the wall-penetrating pipeline can pass. The other end of the steel hollow cylindrical tube 5-2 is embedded inside the steel circular tube 1, and its end is in close contact with the rubber water-stop ring 4. In addition, the center of the steel hollow cylindrical tube 5-2 coincides with the center of the steel circular plate 5-1, and the inner wall of the steel hollow cylindrical tube 5-2 also coincides with the inner wall of the circular hole at the center of the steel circular plate 5-1. This design ensures that the wall-penetrating pipeline can pass smoothly and maintain a tight connection with all components.

[0020] A hollow cylindrical steel tube 5-2 is located at one end of a circular steel tube 1, and an L-shaped fastener 5-3 is integrally provided thereon. Simultaneously, the inner wall of the circular steel tube 1 has an opening that engages with the L-shaped fastener 5-3. During actual installation, the L-shaped fastener 5-3 can be aligned with the opening at the end of the circular steel tube 1 and pressed inwards until it extends into the opening. Then, it can be rotated counterclockwise, causing the L-shaped fastener 5-3 to engage with the opening at the end of the circular steel tube 1, thereby firmly fixing the metal plug 5.

[0021] Finally, asphalt paste 6 will be applied to the joint between the steel circular steel plate 5-1 on the upper part of the metal plug 5, the asphalt hemp fiber 3, and the wall-penetrating pipeline to perform secondary sealing and ensure that the waterproof performance of the entire wall-penetrating flexible waterproof sleeve device reaches the best state.
