Description

Technical Field

[0001] The utility model belongs to the technical field of floor anti-seepage, and particularly relates to an anti-seepage structure for reserved holes in cast-in-place floors. Background Art

[0002] With the continuous improvement of people's requirements for the living environment, the water supply and drainage system is particularly important in people's production and life. Although the indoor water supply and drainage project accounts for a small proportion in the overall construction project, the requirements for the construction quality are very high. Especially for the plugging operation at the reserved holes of pipes and floors, if the plugging is not thorough, leakage will occur under the long-term action of water, causing damage to the floor structure and posing a safety hazard.

[0003] At present, the traditional construction method is to use concrete to plug the reserved holes of pipes and floors. However, due to the poor adhesion effect of concrete on the pipe wall, the bonding effect between the secondary concrete and the pipe wall of the water pipe, and between the secondary concrete and the floor concrete is not good, resulting in a poor plugging effect. Once there is an intrusion of surface water, there will be a large potential for leakage around the water pipe on the floor. Content of the Utility Model

[0004] In view of the above-mentioned disadvantages of the prior art, the purpose of the present utility model is to provide an anti-seepage structure for reserved holes in cast-in-place floors, which is used to solve the problems of poor plugging effect and easy water seepage at the reserved holes of pipes and floors in the prior art.

[0005] To achieve the above object and other related objects, the present utility model provides an anti-seepage structure for reserved holes in cast-in-place floors, including:

[0006] A pipe body, which is penetrated through the reserved hole in the floor;

[0007] A plugging formwork, which is sleeved on the outer wall of the pipe body and abuts against the bottom of the floor;

[0008] A plugging layer, which is filled between the inner wall of the reserved hole in the floor and the outer wall of the pipe body;

[0009] An anti-seepage component, which includes an inclined plate and a water stop plate. Two ends of the inclined plate are respectively fixedly connected to the outer wall of the pipe body and one end of the water stop plate. The water stop plate is horizontally arranged on the top of the floor and completely covers the plugging layer. There are at least two plugging holes on the water stop plate, and at least two of the plugging holes are communicated with the plugging layer. There are water seepage holes on the outer wall of the pipe body, and the water seepage holes are located above the upper end of the outer wall of the pipe body fixedly connected with the inclined plate;

[0010] A sealing component, which is used to seal the connection position between the anti-seepage component and the floor.

[0011] Optionally, the sealing assembly includes an annular water retaining platform, a first seal, and a second seal. The annular water retaining platform is fixedly connected to the top of the floor slab. The bottom of the water retaining platform has an upwardly concave groove, and the groove is fixedly connected to the water stop plate. A water seepage space is formed between the pipe body, the inclined plate, and the inner wall of the groove. The annular water retaining platform is provided with a water leakage hole, and the diameter of the water leakage hole is larger than the outer diameter of the pipe body.

[0012] The first seal is disposed at the intersection of the inclined plate, the water stop plate, and the annular water retaining platform.

[0013] The second seal is disposed at the intersection of the annular water retaining platform and the floor slab.

[0014] Optionally, both the first seal and the second seal are sealants.

[0019] Optionally, the pipe body, the inclined plate, and the water stop plate are integrally formed.

[0020] Optionally, the plugging layer is micro-expansion fine stone concrete.

[0021] As described above, a cast-in-place floor slab reserved hole anti-seepage structure of the present utility model has at least the following beneficial effects:

[0022] The water on the top of the floor slab is guided into the pipe body by the inclined plate and flows away, so that the water is far away from the connection part between the pipe body and the floor slab, thereby preventing water seepage. The water stop plate is horizontally arranged on the top of the floor slab and completely covers the plugging layer, thereby blocking the moisture on the top of the floor slab from infiltrating into the plugging layer and around the pipe body, improving the anti-seepage effect.

[0023] The connection position between the anti-seepage component and the floor slab is sealed by a sealing component, further preventing moisture from seeping in through the gaps between the anti-seepage component and the floor slab, and jointly forming a complete waterproof system with the anti-seepage component, effectively improving the waterproof performance and durability at the pipe body and the reserved hole of the floor slab.

[0031] The following various embodiments are only for illustration purposes. Combinations can be made between the various embodiments, and it is not limited to the content shown in the following single embodiment.

[0032] In this embodiment, please refer to Figures 1 to 3 , this utility model provides a leakage prevention structure for the reserved hole of a cast-in-place floor slab 2, including:

[0033] A pipe body 1, a plugging formwork 3, a plugging layer 4, a seepage prevention component 5, and a sealing component 6. The pipe body 1 passes through the reserved hole of the floor slab 2; the plugging formwork 3 is sleeved on the outer wall of the pipe body 1 and abuts against the bottom of the floor slab 2, which helps to accurately determine the position of the pipe body 1 in the reserved hole of the floor slab 2, keep it vertical and stable, and prevent the pipe body 1 from shaking or shifting; the plugging layer 4 is filled between the inner wall of the reserved hole of the floor slab 2 and the outer wall of the pipe body 1, which not only plays a waterproof role but also provides a lateral supporting force to the pipe body 1, fills the gap between the pipe body 1 and the inner wall of the reserved hole of the floor slab 2, and makes the pipe body 1 and the floor slab 2 form an integral structure; the seepage prevention component 5 includes an inclined plate 51 and a water stop plate 52. Both the inclined plate 51 and the water stop plate 52 are annular. Two ends of the inclined plate 51 are respectively fixedly connected to the outer wall of the pipe body 1 and one end of the water stop plate 52. The water stop plate 52 is horizontally arranged on the top of the floor slab 2 and completely covers the plugging layer 4. There are at least two plugging holes 53 on the water stop plate 52. During the construction process, construction workers can grout through the plugging holes 53 and observe the filling situation of the plugging layer 4 to ensure that the plugging layer 4 is filled densely. At least two of the plugging holes 53 communicate with the plugging layer 4. There is a seepage hole 54 on the outer wall of the pipe body 1, and the seepage hole 54 is located above the end where the outer wall of the pipe body 1 is fixedly connected to the inclined plate 51; the sealing component 6 is used to seal the connection position between the seepage prevention component 5 and the floor slab 2.

[0034] The water at the top of the floor slab 2 is guided into the pipe body 1 by the inclined plate 51 and flows away, so that the water is far away from the connection part of the pipe body 1 and the floor slab 2, thereby preventing water leakage. The water stop plate 52 is horizontally arranged on the top of the floor slab 2 and completely covers the sealing layer 4, thereby blocking the moisture on the top of the floor slab 2 from seeping into the sealing layer 4 and around the pipe body 1, improving the anti-leakage effect. The sealing component 6 seals the connection position between the anti-seepage component 5 and the floor slab 2, further preventing moisture from seeping in from the gap between the anti-seepage component 5 and the floor slab 2, and jointly forms a complete waterproof system with the anti-seepage component 5, effectively improving the waterproof performance and durability of the reserved hole of the pipe body 1 and the floor slab 2.

[0035] In this embodiment, please refer to Figure 2 and Figure 3 Figure, the sealing component 6 includes an annular water retaining platform 61, a first seal 62 and a second seal 63. The annular water retaining platform 61 is fixedly connected to the top of the floor slab 2. The bottom of the water retaining platform has an upward concave groove, and the groove is fixedly connected to the water stop plate 52. An infiltration space is formed between the pipe body 1, the inclined plate 51 and the inner wall of the groove. A water leakage hole 64 is provided on the annular water retaining platform 61, and the diameter of the water leakage hole 64 is larger than the outer wall diameter of the pipe body 1. The first seal 62 is arranged at the intersection of the inclined plate 51, the water stop plate 52 and the annular water retaining platform 61. The second seal 63 is arranged at the intersection of the annular water retaining platform 61 and the floor slab 2.

[0036] By fixedly connecting the annular water retaining platform 61 to the top of the floor slab 2 and fixedly connecting the groove at its bottom to the water stop plate 52, a waterproof structure surrounding the pipe body 1 is formed, which can effectively prevent external moisture from seeping into the connection part of the anti-seepage component 5 and the floor slab 2, thereby enhancing the waterproof performance of the connection of the entire pipe body 1 and the reserved hole of the floor slab 2. Since the annular water retaining platform 61 is provided with a water leakage hole 64 with a diameter larger than the outer wall diameter of the pipe body 1, and an infiltration space is formed between the pipe body 1, the inclined plate 51 and the inner wall of the groove, when there is water on the top of the floor slab 2, the water can quickly gather at the water leakage hole 64 through the infiltration space and be discharged, avoiding the accumulation of moisture inside the sealing component 6 and preventing damage to the structure of the sealing component 6 and the floor slab 2 due to excessive water accumulation. The first seal 62 is arranged at the intersection of the inclined plate 51, the water stop plate 52 and the annular water retaining platform 61. The first seal 62 can fill the tiny gaps at the intersection, prevent moisture from seeping through these gaps, and improve the waterproof effect of the sealing component 6 at the key part. The second seal 63 is arranged at the intersection of the annular water retaining platform 61 and the top of the floor slab 2, and can prevent moisture from seeping in from the connection surface of the annular water retaining platform 61 and the floor slab 2.

[0037] In this embodiment, please refer to Figure 2 and Figure 3, both the first seal 62 and the second seal 63 are sealants. Sealants have good sealing performance and durability. During construction, they can fully fill various irregular and tiny gaps at the intersection of the inclined plate 51, the water stop plate 52, and the annular water retaining platform 61, as well as at the intersection of the annular water retaining platform 61 and the floor slab 2, thus having good sealing performance. Using sealants for construction has a simple process, reduces construction difficulty, saves construction time costs, and sealants are common sealing materials with low material costs.

[0038] In this embodiment, please refer to Figure 2 , a plurality of water seepage holes 54 are equidistantly arranged along the circumferential direction of the outer wall of the pipe body 1. The plurality of water seepage holes 54 can be four, and the four water seepage holes 54 are evenly distributed along the circumferential direction of the outer wall of the pipe body 1, which can achieve uniform drainage, timely drain the water, and ensure the waterproof performance of the reserved hole between the pipe body 1 and the floor slab 2.

[0039] In this embodiment, please refer to Figure 2 , the water seepage holes 54 are inclined at the same angle as the inclined plate 51. The design that the water seepage holes 54 are inclined at the same angle as the inclined plate 51 enables the water entering from the leakage hole 64 to flow along the inclined plate 51, improving the drainage efficiency.

[0040] In this embodiment, please refer to Figure 2 , the diameter of the water seepage holes 54 is 5 - 10 mm. The diameter of the water seepage holes 54 being 5 - 10 mm can not only timely drain the water into the pipe body 1 but also prevent blockage.

[0041] In this embodiment, please refer to Figure 2 , seal adhesives 7 are provided between the plugging layer 4 and the outer wall of the pipe body 1, between the plugging layer 4 and the inner wall of the reserved hole of the floor slab 2, and between the inclined plate 51 and the plugging layer 4. Through the seal adhesives 7, the connection strength between the plugging layer 4 and the outer wall of the pipe body 1, the inner wall of the reserved hole of the floor slab 2, and the inclined plate 51 can be enhanced. The plugging layer 4 plays a role of filling and sealing in the whole structure. When its connection with the surrounding components is strengthened by the seal adhesives 7, the whole structure can maintain better integrity when bearing external forces and can also provide better waterproof performance.

[0042] In this embodiment, please refer to Figure 2 or Figure 3 , the pipe body 1, the inclined plate 51, and the water stop plate 52 are integrally formed. Through integral forming, a continuous waterproof barrier is formed, and water cannot seep into the structure interior through gaps, greatly improving the waterproof performance of the whole structure.

[0043] In this embodiment, please refer to Figure 2, the plugging layer 4 is micro-expansion fine stone concrete. The micro-expansion property enables the fine stone concrete to generate a certain amount of expansion during the setting and hardening process, which can effectively fill the gap between the inner wall of the reserved hole in the floor slab 2 and the outer wall of the pipe body 1, ensuring that the plugging layer 4 is in close contact with the surrounding structure and preventing the formation of gaps caused by concrete shrinkage. It can effectively prevent the formation of leakage channels and greatly improve the waterproofness and durability of the plugging layer 4.

[0044] Working principle: When in use, it includes the following steps:

[0045] Reserving the hole: When pouring the floor slab 2, use a straight-wall mold to reserve the hole;

[0046] Installing the plugging formwork 3: Sleeve the plugging formwork 3 on the outer wall of the pipe body 1 and abut and fix the plugging formwork 3 against the bottom of the floor slab 2;

[0047] Applying the sealing adhesive 7: Apply the sealing adhesive 7 between the plugging layer 4 and the outer wall of the pipe body 1, the inner wall of the reserved hole in the floor slab 2, and the inclined plate 51. The sealing adhesive 7 can enhance the connection strength between the plugging layer 4 and the outer wall of the pipe body 1, the inner wall of the reserved hole in the floor slab 2, and the inclined plate 51;

[0048] Filling the plugging layer 4: Inject the micro-expansion fine stone concrete from the plugging hole 53 to solidify and form the plugging layer 4. During the construction process, the construction personnel can inject slurry through the plugging hole 53 and observe the filling situation of the plugging layer 4 to ensure that the plugging layer 4 is filled densely. After the plugging layer 4 is filled, seal the plugging hole 53 with micro-expansion fine stone concrete;

[0049] Sealing construction: The material of the annular water retaining platform 61 is processed with micro-expansion fine stone concrete. It is fixedly connected to the top of the floor slab 2 through the annular water retaining platform 61, and its bottom groove is fixedly connected to the water stop plate 52, forming a waterproof structure surrounding the pipe body 1, which can effectively prevent external water from seeping into the connection part between the anti-seepage component 5 and the floor slab 2, thereby enhancing the waterproof performance of the connection between the entire pipe body 1 and the reserved hole in the floor slab 2. The first seal 62 and the second seal 63 respectively fully fill various irregular and tiny gaps at the intersection of the inclined plate 51, the water stop plate 52 and the annular water retaining platform 61 and at the intersection of the annular water retaining platform 61 and the floor slab 2, so as to have good sealing performance, and guide the water on the top of the floor slab 2 to flow into the pipe body 1 and away from the connection part between the pipe body 1 and the floor slab 2, thereby being able to prevent water leakage and improve the anti-seepage effect.

[0050] In summary, the utility model guides the water on the top of the floor slab 2 to flow away inside the pipe body 1 through the inclined plate 51, so that the water is far away from the connection part of the pipe body 1 and the floor slab 2, thereby preventing water leakage. The water stop plate 52 is horizontally arranged on the top of the floor slab 2 and completely covers the sealing layer 4, thus blocking the moisture on the top of the floor slab 2 from infiltrating into the sealing layer 4 and around the pipe body 1, and improving the anti-leakage effect. The connection position between the anti-seepage component 5 and the floor slab 2 is sealed by the sealing component 6, further preventing moisture from infiltrating from the gap between the anti-seepage component 5 and the floor slab 2, and jointly forming a complete waterproof system with the anti-seepage component 5, effectively improving the waterproof performance and durability of the reserved hole of the pipe body 1 and the floor slab 2. The annular water retaining platform 61 is fixedly connected to the top of the floor slab 2, and the groove at its bottom is fixedly connected to the water stop plate 52, forming a waterproof structure surrounding the pipe body 1, so that the external moisture can be effectively prevented from infiltrating from the connection part of the anti-seepage component 5 and the floor slab 2, thereby enhancing the waterproof performance of the connection of the entire pipe body 1 and the reserved hole of the floor slab 2. The annular water retaining platform 61 is provided with a water leakage hole 64 with a diameter larger than the outer wall diameter of the pipe body 1, and a water seepage space is formed between the pipe body 1, the inclined plate 51 and the inner wall of the groove. When there is water on the top of the floor slab 2, the water can quickly gather at the water leakage hole 64 through the water seepage space and be discharged, avoiding the accumulation of moisture inside the sealing component 6 and preventing damage to the structures of the sealing component 6 and the floor slab 2 due to excessive water accumulation. The first sealing member 62 is arranged at the intersection position of the inclined plate 51, the water stop plate 52 and the annular water retaining platform 61. The first sealing member 62 can fill the tiny gaps at the intersection, preventing moisture from infiltrating from these gaps and improving the waterproof effect of the sealing component 6 at the key position. The second sealing member 63 is arranged at the intersection position of the annular water retaining platform 61 and the top of the floor slab 2, and can prevent moisture from infiltrating from the connection surface of the annular water retaining platform 61 and the floor slab 2. Therefore, the utility model effectively overcomes various shortcomings in the prior art and has high industrial utilization value.

[0051] The above embodiments are only illustrative of the principles and effects of the utility model, and are not used to limit the utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the utility model. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the utility model should still be covered by the claims of the utility model.
