Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a water-stop sleeve for a layout hole. Background Technology

[0002] Floor layout holes are common in the current construction industry. Their purpose is to ensure accurate layout of the upper floors during construction. These holes are pre-drilled on each floor to transfer control points from one floor to the next. This not only guarantees the structural safety and spatial quality of the building but also improves the efficiency and precision of construction.

[0003] Traditional construction layout holes are often pre-drilled using wedge-shaped wooden boxes or PVC sleeves without waterproofing. While this ensures accurate transmission of control points, it creates hidden dangers for later sealing. Firstly, if the wedge-shaped wooden boxes are not reinforced with steel bars, cracks will inevitably form along the corners after the concrete has set, directly affecting the quality of the concrete. Secondly, during sealing, the concrete slab sidewalls need to be roughened. Improper roughening will affect the bonding between the old and new concrete, increasing the risk of floor leakage. Finally, if PVC sleeves without waterproofing are used, a specialist must chisel away the embedded sleeves before roughening the floor slab sidewalls, incurring additional labor costs, which can be a significant expense for large-scale projects. Utility Model Content

[0004] One objective of this utility model is to provide a water-stop sleeve for the layout hole, which solves the technical problem that the pre-reserved parts for the layout hole are prone to cracking or increase the risk of floor leakage in the prior art.

[0026] Figure 1 This is a schematic structural diagram of the water-stop sleeve 100 for the wire hole according to an embodiment of the present invention. Figure 2 yes Figure 1 A schematic structural diagram of the first sleeve 10 of the wire-laying hole water-stop sleeve 100 shown. Figure 3 yes Figure 1 A schematic structural diagram of the second sleeve 20 of the water-stop sleeve 100 for the wire-laying hole shown. Figure 4 yes Figure 1 A schematic cross-sectional view of the water-stop sleeve 100 for the cable-laying hole is shown. Figures 1 to 4As shown, in some embodiments, the water-stop sleeve 100 for the wiring hole includes a first sleeve 10 and a second sleeve 20. The first sleeve 10 includes a first flange plate 11 and a first connecting pipe 12 that are perpendicular to each other. The outer wall of the first connecting pipe 12 is provided with a first thread 121, and the inner wall is provided with a first water-stop ring 122. The second sleeve 20 includes a second flange plate 21 and a second connecting pipe 22 that are perpendicular to each other. The inner wall of the second connecting pipe 22 is provided with a second thread 221, and the outer wall is provided with a second water-stop ring 222. The first sleeve 10 and the second sleeve 20 are connected by the cooperation of the first thread 121 and the second thread 221. Here, the second sleeve 20 with the second water-stop ring 222 is pre-embedded to achieve the effect of primary water-stopping. When the on-site construction conditions reach the conditions for sealing the opening, the matching first sleeve 10 with the first water-stop ring 122 is tightened onto the second sleeve 20. After tightening, concrete can be poured to achieve the effect of secondary water-stopping.

[0027] This embodiment avoids the quality risks of floor slab cracking caused by using wedge-shaped wooden boxes through the design of the first sleeve 10 and the second sleeve 20. Once the opening is sealed, the second sleeve 20 is simply tightened to the first sleeve 10. The design of the first water-stop ring 122 and the second water-stop ring 222 achieves a water-stopping effect, reducing the risk of floor slab leakage. No chiseling is required, saving the labor costs associated with using ordinary PVC sleeves. Furthermore, the threaded connection between the first sleeve 10 and the second sleeve 20 allows for flexible adjustment of the installation height of the water-stop sleeve 100 for the wiring hole, making it highly adaptable.

[0028] In some embodiments, the height of the first sleeve 10 and the second sleeve 20 can be designed according to the thickness of the floor slab. Then, through the cooperation of the first thread 121 and the second thread 221, the total height of the first sleeve 10 and the second sleeve 20 can be adjusted, so that it can be freely adjusted according to the thickness of the floor slab.

[0029] In some embodiments, the first water-stop ring 122 has a straight portion 123 and an inclined portion 124, the inclined portion 124 being inclined upward from one end of the straight portion 123. In this embodiment, the first water-stop ring 122 is designed to be inclined upward, and the outer edge of the first water-stop ring 122 forms a reverse slope, making it difficult for water to pass over the first water-stop ring 122 and enter the hole.

[0030] In some embodiments, the outer surfaces of the first water-stop ring 122 and the second water-stop ring 222 both have a serrated structure or a corrugated structure, which can improve the adhesion and water-stopping ability with the concrete interface.

[0031] In some embodiments, the number of first water-stop rings 122 and second water-stop rings 222 can be set to multiple, with multiple first water-stop rings 122 arranged sequentially at vertical intervals along the first connecting pipe 12. Multiple second water-stop rings 222 are arranged sequentially at vertical intervals along the second connecting pipe 22. This embodiment can further improve the water-stopping effect by designing multiple first water-stop rings 122 and multiple second water-stop rings 222.

[0032] In some embodiments, the drain hole waterstop sleeve 100 further includes a first expansion waterstop strip 30 and a second expansion waterstop strip 40. The first expansion waterstop strip 30 is located on the side of the first flange plate 11 facing the second flange plate 21 and expands after absorbing water. The second expansion waterstop strip 40 is located on the side of the second flange plate 21 facing the first flange plate 11 and expands after absorbing water.

[0033] In this embodiment, the first expansion waterstop strip 30 and the second expansion waterstop strip 40 can expand when exposed to water, which can enhance the water-stopping effect.

[0034] In some embodiments, both the first expansion waterstop strip 30 and the second expansion waterstop strip 40 are annular. In other embodiments, the shapes of the first expansion waterstop strip 30 and the second expansion waterstop strip 40 can be determined according to specific design requirements.

[0035] In some embodiments, both the first expansion waterstop strip 30 and the second expansion waterstop strip 40 are installed by adhesive bonding. That is, the first expansion waterstop strip 30 is adhesively bonded to the side of the first flange plate 11 facing the second flange plate 21, and the second expansion waterstop strip 40 is adhesively bonded to the side of the second flange plate 21 facing the first flange plate 11.

[0036] In another embodiment, the first flange plate 11 has a first limiting groove on the side facing the second flange plate 21, and the first expansion waterstop strip 30 is limited within the first limiting groove. The second flange plate 21 has a second limiting groove on the side facing the first flange plate 11, and the second expansion waterstop strip 40 is limited within the second limiting groove, to prevent the first expansion waterstop strip 30 and the second expansion waterstop strip 40 from shifting during construction or use and to improve the reliability of waterstopping. It can be understood that the expansion waterstop strip can be installed on the flange plate by adhesive or by installation within the limiting groove. In other embodiments, the first expansion waterstop strip 30 and the second expansion waterstop strip 40 can also be installed by other methods.

[0037] In some embodiments, the outer surfaces of both the first thread 121 and the second thread 221 are provided with a waterproof coating. Here, the waterproof coating can be an epoxy resin, polyurethane, or fluorocarbon coating, which has excellent water resistance, alkali resistance, and adhesion. During construction, the waterproof coating forms a dense barrier layer, preventing external moisture or concrete grout from seeping in along the thread gaps. Furthermore, the waterproof coating prevents oxidation or corrosion of the threaded metal surface in humid environments, maintains thread engagement accuracy and mechanical strength, and ensures that the first sleeve 10 and the second sleeve 20 maintain a stable and reliable water-stopping effect under long-term service conditions.

[0038] In some embodiments, the outer sides of both the first thread 121 and the second thread 221 are wrapped with PTFE tape. The PTFE tape has good ductility and chemical stability, and can be squeezed into the gap between the two threads during the engagement of the first thread 121 and the second thread 221, forming a dense sealing layer. This sealing layer not only effectively prevents water slurry or moisture from seeping into the thread gap during concrete pouring, but also absorbs stress caused by minor deformation during long-term use, thereby maintaining the sealing stability of the connection. Furthermore, the PTFE tape generates a certain frictional damping effect after the threads are engaged, preventing the threaded connection from loosening due to construction vibration, temperature differences, or water pressure fluctuations, further improving the anti-loosening and anti-seepage reliability of the waterstop sleeve 100 for the laying hole.

[0039] In some embodiments, both the first water-stop ring 122 and the second water-stop ring 222 are made of rigid materials. Here, the rigid material can be made of stainless steel or copper. The rigid water-stop rings maintain their shape during concrete pouring and curing, and will not deform due to external forces or temperature changes, thus forming a stable mechanical embedment at the interface between the sleeve and the concrete. This structure not only effectively prevents the formation of seepage channels but also improves the overall compressive strength and durability of the sleeve, significantly enhancing the reliability of the water-stopping mechanism.

[0040] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
