[0002] The pre-reserved hole sealing structure in floor slab construction is a specially designed structure to solve the problem of leakage in pre-reserved holes during floor slab construction. It is composed of a variety of materials and components. These materials work together to form a tight and durable sealing layer around the hole, effectively blocking water penetration. This ensures that even under different water pressure, humidity and other environmental factors during the long-term use of the building, it can still maintain a good anti-seepage effect, thus protecting the integrity and waterproof performance of the floor slab.

[0003] A search revealed Chinese Patent Publication No. CN221856294U, which discloses a seepage-proof sealing structure for pre-reserved holes in floor slab construction. The structure includes floor slab holes, a floor slab enlargement groove, a first concrete filler, a second concrete filler, a waterproof coating interlayer, and a waterproof coating surface layer. The floor slab holes are through-holes extending into the floor slab. The floor slab enlargement groove is a groove located above the floor slab holes and has a diameter larger than the holes, with the upper opening of the floor slab holes located within the enlargement groove. The first concrete filler fills the floor slab holes. The second concrete filler fills the floor slab enlargement groove. A waterproof coating interlayer is provided between the floor slab enlargement groove and the second concrete filler. A waterproof coating surface layer is provided on the surface of the second concrete filler, extending outwards to cover the transition joint between the floor slab and the floor slab enlargement groove. This structure offers advantages such as tiered construction and improved seepage prevention. However, due to the varying sizes of the holes, the sealing structure cannot be applied to holes of different specifications, potentially leading to water seepage. Utility Model Content

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0039] Reference Figure 1 and Figure 4This utility model provides an embodiment of a seepage-proof sealing structure for pre-reserved holes in floor slab construction, including a pre-reserved groove pipe 1, an expansion box 3 in the middle of the pre-reserved groove pipe 1, a knob 4 on the top of the expansion box 3, and a rotating shaft 5 fixedly connected to the bottom of the knob 4. Rotating the knob 4 drives the rotating shaft 5 to rotate. A metal gear 6 is fixedly connected to the bottom of the rotating shaft 5, which in turn drives the metal gear 6 to rotate. A semi-circular locking block 1 7 is provided on the left side of the expansion box 3, and a toothed rod 1 8 is fixedly connected to the right side of the semi-circular locking block 1 7. The front side of the outer wall of the metal gear 6 meshes with the toothed rod 1 8. A semi-circular locking block 2 9 is provided on the right side of the expansion box 3, and a semi-circular locking block 2 9 is fixedly connected to the left side of the semi-circular locking block 2 9. A toothed rod 10 is fixedly connected, and the rear side of the outer wall of the metal gear 6 meshes with the toothed rod 10, which allows the semi-circular locking block 7 and the semi-circular locking block 9 to unfold to both sides. A warning mechanism 2 is installed at the bottom of the reserved groove tube 1. The warning mechanism 2 is used to provide a warning when the reserved groove tube 1 leaks. A rubber ring 11 is provided at the bottom end of the reserved groove tube 1. A screw 12 is threadedly connected to the outer side of the rubber ring 11. The rubber ring 11 is fixed by the screw 12. Multiple warning stickers 13 are equidistantly arranged on the outer wall of the reserved groove tube 1. A screw 22 is threadedly connected to the outer side of the warning sticker 13. The warning sticker 13 is fixed by the screw 22 and serves as a warning.

[0040] Specifically, when sealing pre-reserved slots 1 of different sizes, the operator rotates the knob 4 to drive the rotating shaft 5 fixed at the bottom to rotate. The bottom of the rotating shaft 5 is equipped with a metal gear 6. The rotation of the gear will cause the meshing toothed rod 1 8 and toothed rod 2 10 to move. Semicircular locking blocks 1 7 and 2 9 are fixed on toothed rod 1 8 and toothed rod 2 10 respectively. In this way, semicircular locking blocks 1 7 and 2 9 can be unfolded to adapt to pre-reserved holes of various sizes and achieve effective sealing. At the bottom of the pre-reserved slot 1, a rubber ring 11 is configured. The outer edge of the rubber ring 11 is connected to screw 1 12 by threads. In addition, a warning sticker 13 is installed on the pre-reserved slot 1. The warning sticker 13 is fixed by screw 2 22 and serves as a warning.

[0041] Reference Figure 2 and Figure 5The reserved slot tube 1 includes a fixing plate 201, which is located at the bottom of the reserved slot tube 1. A connecting column 202 is fixedly connected to the top of the fixing plate 201. A spring 203 is fixedly connected to the top of the connecting column 202. The spring 203 rebounds under pressure. A connecting block 204 is fixedly connected to the top of the spring 203. A sponge 205 is fixedly connected to the top of the connecting block 204. A pressing block 206 is fixedly connected to the bottom right end of the connecting block 204. A pressure sensor 207 is installed on the top right end of the fixing plate 201. A slot 14 is opened on the front side of the top of the reserved slot tube 1. A cover plate 15 is provided on the top of the reserved slot tube 1 to provide preliminary protection for the reserved holes. A placement block 16 is fixedly connected to the upper middle part of the left side of the outer wall of the reserved slot tube 1. A handle 17 is fixedly connected to the outside of the placement block 16 to facilitate the operation of the operator.

[0042] Specifically, a fixing plate 201 is set at the lower end of the reserved slot tube 1, and a connecting post 202 is installed on top of it. A spring 203 is arranged on the connecting post 202. The spring 203 has the functions of pressing down and rebounding. A connecting block 204 is fixed above the spring 203. A sponge 205 is attached to the surface of the connecting block 204. In the event of leakage, the sponge 205 absorbs water and its weight increases, thereby applying pressure to the spring 203. A pressure sensor 207 is installed at the bottom of the connecting block 204. When the pressing block 206 acts on the pressure sensor 207, an alarm will be issued. A slot 14 is provided at the top of the reserved slot tube 1. A cover plate 15 is arranged at the top of the reserved slot tube 1 for initial waterproofing. A placement block 16 is installed on the reserved slot tube 1. A handle 17 is provided on the outside of the placement block 16. The pressure sensor 207 is a GemsCL.

[0043] Reference Figure 3 A rubber ring 18 is provided on the outside of the knob 4. A screw 19 is threadedly connected to the outside of the rubber ring 18. The rubber ring 18 is fixed by the screw 19. A fixing rod 20 is fixedly connected to the top of the knob 4. A ring 21 is fixedly connected to the top of the fixing rod 20. The knob 4 can be operated better through the ring 21.

[0044] Specifically, a rubber ring 18 is specially designed on the outer part of the knob 4. This rubber ring 18 not only increases the grip of the knob 4, but also plays a certain role in anti-slip. In addition, the outer side of the rubber ring 18 is designed with threads, which can be easily connected to the screw 19. The addition of the screw 19 makes the knob 4 more secure and also facilitates the connection with other components. A fixing rod 20 is fixed on the top of the knob 4. The design of the fixing rod 20 makes the knob 4 more stable to operate. A ring 21 is fixedly connected to the top of the fixing rod 20, which improves the convenience and accuracy of operation.

[0045] Working Principle: During the sealing operation, the operator needs to precisely seal the pre-reserved slots 1 of different sizes. The operator first rotates knob 4, which in turn rotates the fixed shaft 5 at the bottom. A metal gear 6 is fixed to the bottom of shaft 5. When shaft 5 rotates, metal gear 6 also rotates, causing the meshing toothed rods 8 and 10 to move accordingly. Semicircular locking blocks 7 and 9 are fixed to toothed rods 8 and 10 respectively. These blocks can unfold to accommodate pre-reserved holes of different sizes. The operator can then flexibly perform the sealing operation according to actual needs, ensuring the best sealing effect for the pre-reserved slots 1.

[0046] At the bottom of the reserved groove 1, a fixing plate 201 is installed. At the top of the fixing plate 201, a connecting post 202 is placed. Above the connecting post 202, a spring 203 is installed. This spring 203 has excellent compressive rebound function, quickly returning to its original shape when subjected to external force, ensuring the stability and reliability of the device. Above the spring 203, a connecting block 204 is installed. This connecting block 204 serves to fix the spring 203. A sponge 205 is attached to the connecting block 204; this sponge 205 has extremely strong water absorption. When leakage occurs, the sponge 205 quickly absorbs water and becomes heavier due to its increased weight. This increased weight directly exerts downward pressure on the spring 203. A pressure sensor 207 is installed at the bottom of the connecting block 204. The pressure sensor 207 can accurately sense the pressure change caused by the sponge 205 absorbing water and becoming heavier. When the pressure reaches a certain level, the pressure sensor 207 will immediately send a signal. The pressing block 206 will directly act on the pressure sensor 207, thereby triggering an alarm and ensuring that leakage problems are detected and dealt with in a timely manner.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
