Abstract
Description
Technical Field
[0001] This utility model relates to the field of basement waterproofing and drainage technology, and in particular to a basement waterproofing and drainage structure for building decoration. Background Technology
[0002] Building decoration is the process of treating the interior and exterior surfaces and spaces of a building in various ways, aiming to protect the main structure, improve its functionality, and beautify the building. With the continuous advancement of urbanization, more and more buildings are building basements to save space. However, basements are subject to the long-term effects of changes in groundwater levels. Since the basement floor is located below the ground, it is frequently eroded by groundwater. Therefore, waterproofing and moisture-proofing measures are an important part of basement building decoration.
[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: In the prior art, the drainage structure collects water into the drainage chamber and then discharges it through the drainage pipe. However, impurities in the water flow can easily clog the drainage pipe, causing water to overflow onto the basement surface and making it difficult to drain the basement normally. Utility Model Content
[0004] To address the aforementioned problems, this utility model provides a basement waterproofing and drainage structure for building decoration.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0006] A basement waterproofing and drainage structure for building decoration includes a cement base layer, a drainage groove formed on the upper surface of the cement base layer, a drainage pipe running through the cement base layer and communicating with the bottom wall of the drainage groove, a waterproof board on the upper surface of the cement base layer, multiple seepage grooves formed on the upper surface of the waterproof board, a basement floor slab on the upper surface of the waterproof board, a stepped groove formed on the upper surface of the basement floor slab, a drainage cover on the stepped groove, multiple drainage holes formed through the upper surface of the drainage cover, and a filter assembly for filtering the drainage pipe installed in the drainage groove. The filter assembly includes a support plate fixed to the inner wall of the drainage groove, a plug-in block fixed to the upper surface of the support plate, and a filter box set on the upper surface of the support plate. The bottom of the filter box has a plug-in groove for plugging into the plug-in block.
[0007] By adopting the above technical solution, the water accumulated on the basement floor enters the drainage channel through the drainage holes on the drainage cover. The drainage holes filter out larger impurities in the water, and the waterproof membrane plays an effective role in preventing seepage. The water flows through the seepage grooves on the upper surface of the waterproof membrane and is discharged into the drainage channel, thereby improving the waterproof and seepage-proof performance of the basement. The water entering the drainage channel is filtered by the filter box and then discharged downward into the drainage pipe, reducing the probability of impurities in the water flow clogging the drainage pipe and facilitating normal drainage of the basement. When the impurities in the filter box are full, the staff only needs to open the drainage cover and remove the filter box from the drainage channel, which is convenient for cleaning the impurities in the filter box.
[0008] Furthermore, all of the aforementioned seepage channels are inclined downwards toward one side of the drainage channel.
[0009] By adopting the above technical solution, the inclined seepage channel causes water to flow towards the drainage channel, which is conducive to the water flowing quickly from the waterproof board into the drainage channel.
[0010] Furthermore, the upper surface of the drain cover is arc-shaped.
[0011] By adopting the above technical solution, the arc-shaped cover plate allows water on the basement floor to move towards the center of the drainage cover under the action of gravity and enter the drainage channel through the drainage hole, which facilitates the rapid flow of water through the drainage cover into the drainage channel.
[0012] Furthermore, the bottom wall of the drainage trough is inclined downwards towards the side facing the drainage pipe.
[0013] By adopting the above technical solution, the inclined bottom wall of the drainage trough causes the filtered water to flow towards the drain pipe, which is conducive to the rapid discharge of the filtered water from the drain pipe.
[0014] Furthermore, a handle is hinged to the upper surface of the filter box.
[0015] By adopting the above technical solution, the handle provides a leverage point for the filter box, making it easier for staff to lift the filter box upwards using the handle.
[0016] Furthermore, a chamfer is provided at the intersection between the upper surface of the plug block and the side wall of the plug block.
[0017] By adopting the above technical solution, the chamfer setting reduces the difficulty of aligning the filter box and the plug-in block, making it easier for staff to align and insert the filter box and the plug-in block.
[0018] Furthermore, an annular groove is formed in the bottom wall of the drainage trough, and an annular plate that is inserted into and cooperates with the annular groove is provided in the drainage trough. A filter screen is fixed on the upper surface of the annular plate.
[0019] By adopting the above technical solution, the filter screen plays a secondary filtration role in the drain pipe, further reducing the probability of drain pipe blockage.
[0020] Furthermore, the cross-section of the filter screen is hemispherical.
[0021] By adopting the above technical solution, the hemispherical filter screen increases the filtration area, allowing impurities to fall off the filter screen and reducing the probability of filter screen clogging.
[0022] Furthermore, the inner wall of the drainage channel is lined with waterproof membrane.
[0023] By adopting the above technical solutions, the waterproof membrane has a good waterproof effect, protects the cement substrate, and reduces the probability of water intrusion into the cement substrate causing damage and corrosion.
[0024] In summary, this utility model has the following beneficial effects:
[0025] 1. In this application, the water accumulated on the basement floor slab enters the drainage trough through the drainage holes on the drainage cover. The drainage holes filter out larger impurities in the water, and the waterproof membrane plays an effective role in preventing seepage. The water flows through the seepage groove on the upper surface of the waterproof membrane and is discharged into the drainage trough, thereby improving the waterproof and seepage-proof performance of the basement. The water entering the drainage trough is filtered by the filter box and then discharged downward into the drainage pipe, reducing the probability of impurities in the water flow clogging the drainage pipe and facilitating normal drainage of the basement. When the impurities in the filter box are full, the staff only needs to open the drainage cover and then remove the filter box from the drainage trough, which is convenient for cleaning the impurities in the filter box.
[0026] 2. In this application, the filter screen plays a secondary filtration role in the drain pipe, further reducing the probability of drain pipe blockage;
[0027] 3. In this application, the waterproof membrane has a good waterproof effect, which protects the cement substrate and reduces the probability of water intrusion into the cement substrate causing damage and corrosion. Attached Figure Description

Detailed Implementation
[0032] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0033] like Figures 1-3 As shown in the embodiment of this application, a basement waterproofing and drainage structure for building decoration is disclosed, including a cement base layer 1, a drainage pipe 2, a waterproof board 3, a basement floor slab 4, a drainage cover 5, and a filter assembly 6.
[0034] The cement base layer 1 is made of cement, and a drainage groove 11 is formed on its upper surface. The drainage pipe 2 is a vertically arranged circular pipe structure that passes through the cement base layer 1 and connects to the drainage groove 11. The waterproof membrane 3 is installed on the upper surface of the cement base layer 1, and multiple seepage grooves 31 are formed on its upper surface. The basement floor slab 4 is installed on the upper surface of the waterproof membrane 3, and stepped grooves 41 are formed on its upper surface. The drainage cover 5 is installed on the stepped grooves 41, and multiple drainage holes 51 are formed through its upper surface.
[0035] A filter assembly 6 is installed inside the drain trough 11. The filter assembly 6 is used to filter the drain pipe 2. The filter assembly 6 includes a support plate 61, a connector block 62, and a filter box 63. The support plate 61 is a rectangular plate structure, fixed to the inner wall of the drain trough 11, and two support plates symmetrically arranged. The connector block 62 is a cuboid structure, fixed to the upper surface of the support plate 61, and two connector blocks 62 are provided and fixed to the upper surfaces of two support plates 61 respectively. The filter box 63 is located on the upper surface of the support plate 61, and the bottom of the filter box 63 has a connector groove 631 for insertion and mating with the connector block 62.
[0036] Water accumulated on the basement floor slab 4 enters the drainage trough 11 through the drainage hole 51 on the drainage cover 5. The drainage hole 51 filters out larger impurities in the water, and the waterproof board 3 effectively prevents seepage. Water flows through the seepage groove 31 on the upper surface of the waterproof board 3 and is discharged into the drainage trough 11, thereby improving the waterproof and seepage-proof performance of the basement. After the water entering the drainage trough 11 is filtered by the filter box 63, it flows downward into the drainage pipe 2, reducing the probability of impurities in the water clogging the drainage pipe 2 and facilitating normal drainage of the basement. When the impurities in the filter box 63 are full, the staff only needs to open the drainage cover 5 and remove the filter box 63 from the drainage trough 11 to facilitate cleaning of the impurities in the filter box 63.
[0037] In order to enable water to flow quickly from the waterproof membrane 3 into the drainage channel 11, multiple seepage channels 31 are inclined downwards towards one side of the drainage channel 11. The inclined seepage channels 31 cause water to flow towards one side of the drainage channel 11, which is conducive to the water flowing quickly from the waterproof membrane 3 into the drainage channel 11.
[0038] In order to facilitate the rapid flow of water through the drainage cover 5 into the drainage channel 11, the upper surface of the drainage cover 5 is arc-shaped. The arc-shaped cover plate causes the water on the basement floor 4 to move towards the center of the drainage cover 5 under the action of gravity and enter the drainage channel 11 through the drainage hole 51, thereby facilitating the rapid flow of water through the drainage cover 5 into the drainage channel 11.
[0039] In order to facilitate the rapid discharge of filtered water from the drain pipe 2, the bottom wall of the drain trough 11 is inclined downwards on the side facing the drain pipe 2. The inclined bottom wall of the drain trough 11 causes the filtered water to flow towards the drain pipe 2, which facilitates the rapid discharge of filtered water from the drain pipe 2.
[0040] To facilitate lifting the filter box 63, a handle 7 is hinged to the upper surface of the filter box 63. The handle 7 provides a point of leverage for the filter box 63, making it easier for the operator to lift the filter box 63 upwards using the handle 7.
[0041] To facilitate the alignment and insertion of the filter box 63 and the plug-in block 62, a chamfer 621 is provided at the intersection between the upper surface of the plug-in block 62 and the side wall of the plug-in block 62. The chamfer 621 reduces the difficulty of aligning the filter box 63 and the plug-in block 62, thus making it easier for the staff to align and insert the filter box 63 and the plug-in block 62.
[0042] To further reduce the probability of blockage in the drain pipe 2, an annular groove 12 is provided on the bottom wall of the drain trough 11. An annular plate 8 is provided in the drain trough 11 to be inserted into the annular groove 12. A filter screen 9 is fixed on the upper surface of the annular plate 8. The filter screen 9 plays a secondary filtration role for the drain pipe 2, thereby further reducing the probability of blockage in the drain pipe 2.
[0043] To reduce the probability of filter screen 9 becoming clogged, the cross-section of filter screen 9 is hemispherical. The hemispherical shape of filter screen 9 increases the filtration area of filter screen 9, allowing impurities to fall off the filter screen 9, thereby reducing the probability of filter screen 9 becoming clogged.
[0044] To reduce the probability of moisture intruding into the cement base layer 1, the inner wall of the drainage channel 11 is covered with a waterproof membrane (not shown in the figure). The waterproof membrane has a good waterproof effect and protects the cement base layer 1, thereby reducing the probability of moisture intruding into the cement base layer 1 and causing damage and corrosion.
[0045] The working principle of a basement waterproofing and drainage structure in this embodiment is as follows:
[0046] Water accumulated on the basement floor slab 4 enters the drainage trough 11 through the drainage hole 51 on the drainage cover 5. The drainage hole 51 filters out larger impurities in the water, and the waterproof board 3 effectively prevents seepage. Water flows through the seepage groove 31 on the upper surface of the waterproof board 3 and is discharged into the drainage trough 11, thereby improving the waterproof and seepage-proof performance of the basement. After the water entering the drainage trough 11 is filtered by the filter box 63, it flows downward into the drainage pipe 2, reducing the probability of impurities in the water clogging the drainage pipe 2 and facilitating normal drainage of the basement. When the impurities in the filter box 63 are full, the staff only needs to open the drainage cover 5 and remove the filter box 63 from the drainage trough 11 to facilitate cleaning of the impurities in the filter box 63.
[0047] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
