Description

Technical Field

[0001] The present application relates to the technical field of indoor waterproof structures, and in particular to a composite baseboard structure for waterproofing the ground of a basement or a semi-basement. Background Art

[0002] A basement refers to a room where the height of its floor is lower than the outdoor ground level by more than one-half of the room's net height; a semi-basement refers to a room where the average height of its indoor floor is lower than the outdoor design ground by more than 1 / 3 but not more than 1 / 2 of the room's average net height.

[0003] Since the indoor floor is lower than the outdoor ground level, both basements and semi-basements need to be strictly waterproofed. Common basement and semi-basement waterproofing projects mostly use traditional rigid waterproof materials for waterproofing, such as waterproof mortar, waterproof concrete, etc. After the waterproof mortar or waterproof concrete is completed, a structural raft is formed, on which floor heating can be laid or other construction can be carried out.

[0004] However, due to the influence of factors such as long-term stress on the basement floor, changes in groundwater pressure, and uneven ground settlement, the rigid waterproof layer (also known as the structural raft) is prone to cracks, leading to water leakage problems. Utility Model Content

[0005] In order to reduce the occurrence of water seepage in basements or semi-basements, the present application provides a composite base plate structure for waterproofing the ground of a basement or semi-basement.

[0006] The composite floor structure for waterproofing the basement or semi-basement provided in this application adopts the following technical solution:

[0007] A composite base plate structure for waterproofing the ground of a basement or semi-basement includes a structural raft of the basement or semi-basement and a decorative layer located above the structural raft, a drainage board is arranged between the decorative layer and the structural raft, the drainage board forms a drainage channel on a side close to the structural raft, a drainage pipe is connected to the drainage board, one end of the drainage pipe is connected to the drainage channel, and the other end is connected to a pre-dug water collection well, and the water in the drainage channel can flow into the water collection well along the drainage pipe.

[0008] By adopting the above technical solution, the drainage board forms a drainage channel on the side close to the structural raft. When the waterproof performance of the structural raft decreases due to uneven ground settlement, water enters the drainage channel. After entering the drainage channel, the water can flow along the drainage pipe to the water collection well to achieve drainage, reducing water seepage inside the basement.

[0009] Optionally, the drainage channels are provided in plurality, and the plurality of drainage channels are interconnected.

[0010] By adopting the above technical solution, the provision of multiple drainage channels makes it possible to adapt to water seepage at different positions of the structural raft, and at the same time, the multiple drainage channels are connected to facilitate the discharge of water.

[0011] Optionally, the height of the drainage channel ranges from 15 mm to 30 mm.

[0012] By adopting the above technical solution, the thickness of the drainage board is controlled to ensure the space of the drainage channel and ensure that the water can be discharged quickly.

[0013] Optionally, a protective layer is provided between the decorative layer and the drainage board, and the protective layer is used to support the decorative layer.

[0014] By adopting the above technical solution, the decorative layer is supported by the protective layer, which facilitates the support of the decorative layer and can prevent moisture from spreading to the decorative layer, thereby protecting the decorative layer.

[0015] Optionally, a moisture-proof layer is provided between the protective layer and the decorative layer, and the moisture-proof layer is used to prevent moisture from spreading toward the decorative layer.

[0016] By adopting the above technical solution, the moisture-proof layer is provided to further prevent moisture from contacting the decorative layer, thereby improving the protective effect of the decorative layer and increasing the service life of the decorative layer.

[0017] Optionally, a waterproof layer is provided between the structural raft and the waterproof board.

[0018] By adopting the above technical solution, a waterproof layer is arranged on the structural raft slab to improve the waterproof effect of the basement or semi-basement waterproofing project.

[0019] Optionally, an anti-back pressure layer is provided between the structural raft and the waterproof layer, and the anti-back pressure layer is used to improve the structural strength of the waterproof layer.

[0020] By adopting the above technical solution, the structural strength of the waterproof layer is improved through the anti-back pressure layer, thereby reducing the occurrence of rupture of the waterproof layer and further improving the waterproof effect of the waterproof layer.

[0021] Optionally, the edge of the waterproof layer is folded in a direction perpendicular to the waterproof layer toward the decorative layer, and extends to a side of the decorative layer away from the drainage board.

[0022] By adopting the above technical solution, the edge of the waterproof layer is folded and wrapped around the drainage board, protective layer and other layer structures, preventing moisture from entering the inner layer structure through the gaps between adjacent layer structures, thereby further improving the waterproof effect of the waterproof project.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. Install drainage boards to implement the concept of prevention first and drainage prevention structure to improve the overall waterproof performance of the basement floor.

[0025] 2. Drain water through drainage channels and drainage pipes to reduce the occurrence of indoor water seepage in basements or semi-basements. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following is combined with Figure 1 This application is described in further detail.

[0029] The embodiments of the present application disclose a composite base plate structure for waterproofing a basement or semi-basement floor.

[0030] Reference Figure 1 The composite floor structure for waterproofing the basement or semi-basement floor comprises a drainage board 1, which is located between the decoration layer 3 of the basement (the decoration layer 3 here refers to a structure that can play a decorative role in the basement, or has certain functions in the basement, such as a floor heating layer, a tile layer, etc.; in this embodiment, the decoration layer 3 is a floor heating layer) and the structural raft 2. The drainage board 1 forms a drainage channel 11 on one side close to the structural raft 2, and a drainage pipe (not shown in the figure) is buried under the drainage board 1. One end of the drainage pipe is connected to the drainage channel 11, and the other end extends to a pre-dug water collection well (not shown in the figure).

[0031] Reference Figure 1 During the long-term use of the basement or semi-basement, when the structural raft 2 is cracked due to uneven settlement of the basement or semi-basement, water penetrates from bottom to top and gathers in the drainage channel 11. The water in the drainage channel 11 can flow to the water collection well along the drainage pipe, realizing the combination of waterproofing and drainage in the construction of the basement or semi-basement, ensuring that the water can be discharged when the waterproof performance of the rigid waterproof structure decreases, and reducing the occurrence of water seepage inside the basement or semi-basement.

[0032] Reference Figure 1 A plurality of drainage channels 11 are arranged on one side of the drainage board 1 close to the structural raft 2, and the plurality of drainage channels 11 are interconnected. On the one hand, the drainage efficiency is improved, and on the other hand, it is convenient to discharge water bodies at different positions.

[0033] Reference Figure 1 The height of the drainage channel 11 is between 15 mm and 30 mm to ensure that the water has enough space to flow and ensure the drainage effect. The thickness of the drainage board 1 in this embodiment is 20 mm, and in other embodiments it can also be 18 mm or 25 mm.

[0034] Reference Figure 1 A protective layer 4 is provided between the decorative layer 3 and the drain board 1. The protective layer 4 separates the drain board 1 from the decorative layer 3. On the one hand, it can prevent moisture from spreading upward and contacting the decorative layer 3. On the other hand, it can prevent the decorative layer 3 from directly contacting the drain board 1, which may cause damage or deformation of the drain board 1. At the same time, the protective layer 4 can support the decorative layer 3, which is convenient for the construction of the decorative layer 3. In this embodiment, the protective layer 4 is fine stone concrete, and the thickness of the protective layer 4 is 45mm-55mm. In this embodiment, the thickness of the protective layer 4 is 50mm, and in other embodiments, it can be 47mm, 52mm, etc.

[0035] Reference Figure 1 A moisture-proof layer 5 is provided between the decorative layer 3 and the protective layer 4. The moisture-proof layer 5 is used to prevent moisture from moving toward the decorative layer 3, so as to further prevent moisture from contacting the decorative layer 3. In this embodiment, the moisture-proof layer 5 is formed after the moisture-proof mortar solidifies, and the thickness of the moisture-proof layer 5 is 3 mm to 8 mm. In this embodiment, the thickness of the moisture-proof layer 5 is 5 mm, and in other embodiments, it can be 4 mm, 6 mm, etc.

[0036] Reference Figure 1 In order to improve the waterproof effect of the structural raft 2, a waterproof layer 6 is provided between the structural raft 2 and the drain board 1. The waterproof layer 6 is formed by coating with a GES-310A type polyurethane waterproof coating with a coating thickness of 1.5 mm. The waterproof layer 6 blocks the water from spreading upward. The edge of the waterproof layer 6 is folded in a direction perpendicular to its own direction toward the decorative layer 3 and extends to the side of the decorative layer 3 away from the drain board 1. The waterproof layer 6 covers each layer structure, further improving the waterproof effect of the waterproof project of the basement or semi-basement.

[0037] Reference Figure 1 An anti-back pressure layer 7 is provided between the structural raft 2 and the waterproof layer 6, and the anti-back pressure layer 7 is used to improve the structural strength of the waterproof layer 6 and further improve the waterproof performance of the waterproof layer 6. In this embodiment, the anti-back pressure layer 7 is formed by coating with an emulsion paint (specifically, the model is DRYLOK Extreme).

[0038] The implementation principle of the composite base plate structure for waterproofing the basement or semi-basement floor in the embodiment of the present application is as follows: during the construction of the basement or semi-basement, a drainage board 1 is pre-installed to allow water to be discharged after the rigid waterproof structure cracks, thereby reducing water seepage in the basement or semi-basement during use.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
