[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0032] Please refer to the attached Figure 1 - attached Figure 3, an embodiment provided by the present utility model: a waterproof structure for a basement floor slab, including a waterproof board 1. A diversion board 3 is arranged on the right side of the waterproof board 1. The left side of the diversion board 3 is in contact with the right side of the waterproof board 1. Diversion layers 14 are opened on the inner walls of the waterproof board 1. A partition board 15 is fixedly connected to the bottom of the inner wall of the diversion layer 14. A filling layer 16 is opened at the bottom of the partition board 15. Diversion holes 11 are opened on the inner walls of the diversion board 3. A drainage board 6 is arranged on the right side of the diversion board 3. The left side of the drainage board 6 is in contact with the right side of the diversion board 3. An inlet 5 is opened on the inner wall of the drainage board 6. A hollow column 7 is fixedly connected to the middle of the inlet 5. Filter holes 8 are opened on the outer walls of the hollow column 7. A drainage hole 9 is opened at the bottom of the drainage board 6. A heat preservation mechanism 2 is fixedly connected to the right side of the diversion board 3 near the edge. The heat preservation mechanism 2 is used for heat preservation. Handling grooves 10 are opened on the inner walls of the inlets 5 near the edge. Absorbent materials and isolation membranes are arranged in multiple filling layers 16;
[0033] Specifically, drainage holes 9 are opened at the bottom of the drainage board 6. These drainage holes 9 can drain water into the sewer, thereby keeping the basement floor slab dry. The handling grooves 10 can conveniently fix and handle the whole structure. An isolation membrane is first laid in the filling layer 16, and then absorbent materials such as sand and gravel are filled on it, thereby performing preliminary waterproofing. The partition board 15 is fixedly arranged obliquely, so that the permeated water in the diversion layer 14 can flow into the drainage board 6.
[0034] Please refer to the attached Figure 1 -attached Figure 3 , the heat preservation mechanism 2 includes a convex block 205. The outer wall of the convex block 205 is fixedly connected to the right side of the diversion board 3. Shallow grooves 203 are opened on the outer walls of the waterproof board 1. Temperature guiding grooves 204 are opened on the inner walls of the waterproof board 1 and the diversion board 3 near the edge. Polystyrene layers 201 are fixedly connected to the bottoms of the waterproof board 1 and the diversion board 3. Rock wool heat insulation layers 202 are fixedly connected to the bottoms of the waterproof board 1 and the diversion board 3. The inner wall of the shallow groove 203 is slidably connected to the outer wall of the convex block 205. Multiple diversion boards 3 are opened at the same horizontal height;
[0035] Specifically, the polystyrene layer 201 can effectively isolate the temperature of the soil at the bottom of the floor slab and the base layer. The rock wool heat insulation layer 202 can isolate the indoor temperature from the temperature inside the floor slab. The two cooperate to reduce the overall heat conduction performance at the bottom. While ensuring the stable installation of the structure, the convex block 205 and the shallow groove 203 leave an installation gap, avoiding the reduction of the heat preservation effect caused by cracking due to thermal expansion and contraction.
[0036] Please refer to the attached Figure 1 -attached Figure 3, anti-slip patterns 4 are fixedly connected to the tops of both the waterproof board 1 and the diversion board 3. The bottom of the hollow column 7 communicates with the inner wall of the drain hole 9. A support column 13 is fixedly connected to the middle of the partition board 15. A support plate 12 is fixedly connected to the inner wall of the diversion hole 11. The left side of the diversion hole 11 communicates with the inner wall of the diversion layer 14. The right side of the diversion hole 11 communicates with the inner wall of the water inlet 5. The multiple partition boards 15 are arranged at equal intervals, and the multiple partition boards 15 are all set at an inclined angle;
[0037] Specifically, the support column 13 can reinforce the waterproof board 1 to improve its bearing capacity inside, the support plate 12 can improve the bearing capacity of the diversion board 3, the anti-slip pattern 4 can enhance the friction on the upper side of the bottom plate, and the bottom of the hollow column 7 communicates with the inner wall of the drain hole 9, so that the water flowing into the hollow column 7 through the filter hole 8 can be discharged into the sewer through the drain hole 9. The left side of the diversion hole 11 communicates with the inner wall of the diversion layer 14, so that the water seeping into the diversion layer 14 can be discharged.
[0038] Working principle: During the installation and laying process, the drainage board 6 is laid in the middle, and then the diversion board 3 is laid around it. Then the waterproof board 1 is laid all over the basement, and the drain hole 9 is connected to the sewer. When the basement gets damp and water seeps up, first through the filling layer 16, in which an isolation film is first laid and then sand and gravel are filled, the seeping water will be isolated and absorbed. Then the water will penetrate through the diversion layer 14 into the diversion layer 14. Since the partition board 15 has an inclined angle, the water seeping up through capillary action will flow along the diversion layer 14 into the diversion board 3, then flow into the water inlet 5 through the diversion hole 11, and finally be discharged into the drain hole 9 through the filter hole 8 on the outer wall of the hollow column 7;
[0039] When the temperature difference between indoors and outdoors is large, or when it is necessary to store items in a heat-insulated manner, the polystyrene layer 201 isolates the temperature inside the waterproof board 1 and the diversion board 3 from the indoor temperature, and the rock wool heat-insulating layer 202 isolates the underground temperature from the temperature of the waterproof board 1 and the diversion board 3, and the internal air is circulated through the heat conduction groove 204 to prevent local temperature from being too low or too high. The fitting of the convex block 205 and the shallow groove 203 leaves an installation gap during installation, so as to prevent cracking caused by thermal expansion and contraction from reducing the heat-insulating effect.
[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
