Description

Technical Field

[0001] This utility model belongs to the field of basement roof drainage technology, and in particular relates to a construction structure for waterproof drainage of basement roof. Background Technology

[0002] Basement roof slabs directly bear the hydrostatic pressure of groundwater. If the waterproofing fails, moisture will seep through the capillary pores of the concrete, causing corrosion of the internal steel reinforcement and reducing the load-bearing capacity; the interior walls will become damp and moldy, affecting their functionality; long-term leakage may cause concrete carbonization, shortening the building's lifespan. Therefore, basement roof slabs usually need to be used with waterproof drainage boards for waterproofing and drainage. Waterproof drainage boards are typically functional boards made of polymer materials and often use a hollow column structure with concave and convex shapes.

[0003] Chinese patent publication number 202323432761.8 discloses a waterproof and drainage construction structure for a basement roof slab, comprising a basement concrete roof slab layer, a polyurethane waterproof and thermal insulation integrated material layer, a cement mortar leveling layer, a drainage collection layer, a soil covering layer, and a greening layer. The polyurethane waterproof and thermal insulation integrated material layer is located as the innermost layer of the basement concrete roof slab layer and covers its entire inner wall. The cement mortar leveling layer is positioned above the polyurethane waterproof and thermal insulation integrated material layer, the drainage collection layer is positioned above the cement mortar leveling layer, and the soil covering layer is positioned above the drainage collection layer. This basement roof slab waterproof and drainage construction structure forms a continuous, seamless shell for the entire basement roof slab. The PDS zero-slope siphon drainage collection system can systematically remove excess moisture from the soil, resulting in fast construction speed and preventing condensation in the basement due to the integrated waterproofing and thermal insulation.

[0004] However, existing technologies have the following problems when used: The waterproofing and drainage structure of basement roof slabs often suffers from problems such as untimely collection of seepage water and obstructed drainage paths, which can easily lead to water accumulation and leakage risks. The poor sealing performance of the connection parts of the drainage structure makes the connection gaps easy to become new seepage points, and the insufficient stability of the installation and fixing of the seals further reduces the reliability of waterproofing. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned technical problems by providing a waterproofing and drainage construction structure for basement roof slabs, comprising: A substrate, the bottom of which is fixedly connected to a water-guiding plate, and a drainage component for collecting infiltrated water is provided on the substrate and the water-guiding plate. A drainage board is provided on the side wall of the substrate, and the water inlet end of the drainage board corresponds to the water outlet of the drainage assembly. One end of the drainage board is provided with a fixing part, and the fixing part is fixedly installed with the water guide plate. A sealing plate is installed between the water inlet plate and the fixing part to prevent seepage water from being discharged between the water inlet plate and the fixing part; A fastener, located at one end of the fixing part, is used to fix the sealing plate between the water inlet plate and the fixing part.

[0006] Furthermore, the drainage assembly includes a waterproof groove, which is formed on the top of the substrate, and a drainage hole is formed at the bottom of the inner cavity of the waterproof groove.

[0007] Furthermore, the inner cavity of the water-guiding plate is provided with a drainage channel, which is connected to the drainage hole, and the outlet end of the drainage channel is adapted to the inlet end of the drainage plate.

[0008] Furthermore, the sidewall of the substrate is provided with a positioning groove, and the top of the drainage plate is provided with a positioning part, which is engaged in the inner cavity of the positioning groove.

[0009] Furthermore, a first limiting groove is provided on both sides of the fixing part, and a second limiting groove is provided at both ends of the sealing plate.

[0010] Furthermore, the fixing member includes a fixing plate and a limiting plate. The fixing plate is located in the inner cavity of the first limiting groove, and the limiting plate is located in the inner cavity of the second limiting groove. A connecting plate is fixedly connected between one end of the limiting plate and the fixing plate.

[0011] Furthermore, the side wall of the fixing plate is provided with screw holes that can be detachably connected to the first limiting groove.

[0012] Furthermore, the drainage board has detachable partitions fixed at both ends.

[0013] Furthermore, a drain pipe is provided on one side of the drain board, and a connecting pipe is connected to the top of the drain pipe. The connecting pipe is inserted into one end of the bottom of the drain board.

[0014] Furthermore, the inner cavity of the drainage plate is fixedly connected with a guide plate for guiding the permeated water to the connecting pipe.

[0015] Compared with existing technologies, the basement roof waterproofing and drainage construction structure of this utility model has the following advantages: 1.

[0022] like Figures 1-6 As shown, a waterproofing and drainage construction structure for a basement roof slab includes: The substrate 100 has a water-guiding plate 130 fixedly connected to its bottom, and a drainage assembly for collecting infiltrated water is provided on the substrate 100 and the water-guiding plate 130. A drainage plate 200 is provided on the side wall of the substrate 100, and the water inlet end of the drainage plate 200 corresponds to the water outlet of the drainage assembly. A fixing part 220 is provided at one end of the drainage plate 200, and the fixing part 220 is fixedly disposed with the water guide plate 130. A sealing plate 240 is provided at the connection between the water inlet plate 130 and the fixing part 220 to prevent seepage water from being discharged between the water inlet plate 130 and the fixing part 220; A fastener is provided at one end of the fixing part 220 and is used to fix the sealing plate 240 between the water inlet plate 130 and the fixing part 220.

[0023] As a preferred example of this utility model, the substrate 100 and the water-guiding plate 130 are fixed together, and the drainage assembly can capture the seepage water from the roof slab to achieve initial collection; the water inlet end of the drainage plate 200 is aligned with the water outlet of the drainage assembly to achieve the discharge of seepage water; the fixing part 220 is fixed to the water-guiding plate 130; the sealing plate 240 can seal the connection gap between the fixing part 220 and the water-guiding plate 130; and the fixing part at the end of the fixing part 220 is used to fix the sealing plate 240, thereby improving the waterproof reliability of the basement roof slab; in some examples of this application, the substrate 100 may include several substrate sub-modules arranged in an array, and the drainage plate 200 is fixed on the side wall of the outermost substrate sub-module.

[0024] In the example of this application, the drainage component includes a waterproof groove 110, which is formed on the top of the substrate 100, and a drainage hole 120 is formed at the bottom of the inner cavity of the waterproof groove 110.

[0025] As a preferred example of this utility model, the waterproof groove 110 has a groove structure that can collect the seepage water above the substrate 100 and achieve rapid drainage of the accumulated water through the drain hole 120. Specifically, the waterproof groove 110 has a slope design to guide the seepage water to the drain hole 120.

[0026] In the example of this application, the inner cavity of the water inlet plate 130 is provided with a drainage channel 140, which is connected to the drainage hole 120. The water outlet end of the drainage channel 140 is adapted to the water inlet end of the drainage plate 200. Specifically, the drainage channel 140 is cross-shaped and is adapted to the adjacent drainage channel 140. The drainage channel 140 that is not connected to the drainage plate 200 is blocked by a sealing plug.

[0027] As a preferred example of this utility model, the drainage channel 140 is connected to the drainage hole 120 on the substrate 100, ensuring that the permeable water discharged from the drainage hole 120 can flow directly into the drainage channel 140. The other end of the drainage channel 140 is matched with the water inlet end of the drainage plate 200 to form a flow guide path, thereby ensuring the smoothness of the drainage process.

[0028] In the example of this application, a positioning groove 150 is provided on the side wall of the substrate 100, and a positioning part 210 is provided on the top of the drainage plate 200. The positioning part 210 is snapped into the inner cavity of the positioning groove 150.

[0029] As a preferred example of this utility model, the positioning groove 150 matches the positioning part 210 provided on the top of the drainage plate 200. During installation, the positioning part 210 can be directly snapped into the inner cavity of the positioning groove 150, providing an installation positioning reference for the drainage plate 200.

[0030] In the example of this application, the fixing part 220 is provided with a first limiting groove 221 on both sides, and the sealing plate 240 is provided with a second limiting groove 241 at both ends.

[0031] As a preferred example of this utility model, the fixing member achieves the fixing of the fixing part 220 and the sealing plate 240 through the first limiting groove 221 and the second limiting groove 241.

[0032] In the example of this application, the fastener includes a fixing plate 250 and a limiting plate 260. The fixing plate 250 is located in the inner cavity of the first limiting groove 221, and the limiting plate 260 is located in the inner cavity of the second limiting groove 241. A connecting plate 261 is fixedly connected between one end of the limiting plate 260 and the fixing plate 250.

[0033] As a preferred example of this utility model, during assembly, the fixing plate 250 is embedded in the inner cavity of the first limiting groove 221 of the fixing part 220, and the limiting plate 260 is correspondingly inserted into the second limiting groove 241 of the sealing plate 240. The connecting plate 261 fixes the ends of the limiting plate 260 and the fixing plate 250 to form an integrated clamping and fixing structure, which can press the sealing plate 240 between the water inlet plate 130 and the fixing part 220, improve the installation stability of the sealing plate 240, and ensure the sealing and anti-leakage effect.

[0034] In the example of this application, the side wall of the fixing plate 250 is provided with a screw hole 251 that can be detachably connected to the first limiting groove 221, and the bolts are used to fix the fixing plate 250 to the first limiting groove 221 through the screw hole 251.

[0035] As a preferred example of this utility model, specifically, the bolt passes through the screw hole 251 on the fixing plate 250, so that the fixing plate 250 and the first limiting groove 221 can be detachably connected.

[0036] In the example of this application, the drainage board 200 is detachably fixed with partitions 280 at both ends.

[0037] As a preferred example of this utility model, the partition 280 can close the port of the drainage plate 200. When the structure enters normal drainage conditions, the partition 280 ensures that the infiltrated water flows inside the drainage plate 200.

[0038] In the example of this application, a drain pipe 270 is provided on one side of the drain board 200, and a connecting pipe 271 is connected to the top of the drain pipe 270. The connecting pipe 271 is inserted into one end of the bottom of the drain board 200. Specifically, the drain pipe 270 can be embedded in the wall.

[0039] As a preferred example of this utility model, the connecting pipe 271 at the top of the drain pipe 270 is connected to one end of the bottom of the drain plate 200 by a plug-in method, so that the seepage water collected in the drain plate 200 can be concentrated and discharged through the drain pipe 270.

[0040] In the example of this application, the inner cavity of the drainage plate 200 is fixedly connected to a guide plate 230 for guiding the permeated water to the connecting pipe 271.

[0041] As a preferred example of this utility model, the guide plate 230 adopts an inclined design, with its inclined direction facing the location of the connecting pipe 271. When the permeated water enters the inner cavity of the drainage plate 200, the guide plate 230 can guide the dispersed water flow and concentrate the water flow to the connecting pipe 271.

[0042] In practical use, the seepage water from the basement ceiling first collects in the waterproof groove 110 at the top of the substrate 100. The seepage water in the waterproof groove 110 flows into the cross-shaped drainage channel 140 in the inner cavity of the water-guiding plate 130 through the drainage hole 120 at the bottom of its inner cavity. The drainage channel 140, which is not connected to the drainage plate 200, is pre-blocked with a sealing plug to limit the direction of water flow. The seepage water in the drainage channel 140 flows into the inlet end of the matching drainage plate 200 through its outlet end. When installing the drainage plate 200, firstly, the positioning part 210 at the top is snapped into the positioning groove 150 on the side wall of the substrate 100 to complete the positioning. Then, the fixing part 220 at one end of the drainage plate 200 is aligned with the water-guiding plate 130. A sealing plate 240 is placed between the fixing part 220 and the water-guiding plate 130. Then, the fixing plate 250 in the fixing member is embedded into the fixing part. Within the first limiting grooves 221 on both sides of 220, bolts are passed through the screw holes 251 on the side wall of the fixing plate 250 to fix the fixing plate 250 to the first limiting grooves 221. At the same time, the limiting plate 260 is embedded into the second limiting grooves 241 at both ends of the sealing plate 240. The limiting plate 260 is fixedly connected to one end of the fixing plate 250 by the connecting plate 261 to complete the fixing of the sealing plate 240. The inclined guide plate 230 in the inner cavity of the drainage plate 200 guides the inflowing permeable water, so that the water flows along the inclined direction of the guide plate 230 to the connecting pipe 271 at one end of the bottom of the drainage plate 200. The permeable water enters the drainage pipe 270 through the connecting pipe 271 and is finally discharged. The two ends of the drainage plate 200 are pre-fixed with partition plates 280 by a detachable structure to close the port, ensuring that the water flows in a directional manner inside the drainage plate 200, thus completing its use.

[0043] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
