Description

Technical Field

[0001] This utility model relates to the field of indoor waterproofing technology, specifically to an indoor waterproofing structure. Background Technology

[0002] Waterproofing during interior decoration is a crucial step in ensuring the long-term durability of a house and preventing leakage problems. It involves multiple areas such as bathrooms, kitchens, balconies, and basements. Waterproofing is a vital part of the interior decoration process. Improper waterproofing can lead to a series of serious problems, affecting not only living comfort but also property damage and safety hazards.

[0003] The Chinese utility model patent with authorization announcement number "CN221646262U" is specifically "an indoor waterproof structure". It includes a concrete floor slab, a stone base fixedly installed on the top surface of the concrete floor slab, the stone base being made of cement and piled on the ground, the surface of the concrete floor slab being tiled, and a water-blocking strip made of marble fixedly installed on the surface of the stone base. The water-blocking strip is set between the wash area and the shower area in the bathroom. The surface of the tiles in the shower area is equipped with waterproof components, which can waterproof the shower area and solve the problem of inconvenience caused by the small space in the shower area when washing anti-slip stones.

[0004] While the aforementioned device can achieve a waterproof effect, water on the surface of the shower area will seep into the tiles through the tile gaps. The water under the tiles cannot drain and cannot dry quickly. Over time, a large amount of sewage will remain under the tiles, emitting an unpleasant and pungent odor, thus affecting the living environment. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an indoor waterproof structure that can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides an interior waterproof structure, including: a floor slab, a waterproof layer on the surface of the floor slab, a permeable layer on the surface of the waterproof layer, a cement mortar leveling layer on top of the permeable layer, a ceramic tile on top of the cement mortar leveling layer, a drain pipe fixedly connected to the bottom of the floor slab, a first filter screen fixedly connected to the top of the drain pipe, a floor drain installed at the top of the first filter screen, a drain pipe fixedly connected to the bottom of the floor drain, and a second filter screen snapped onto the top of the floor drain.

[0008] Furthermore, the waterproof layer includes a ground sloping layer, which is laid on the surface of the floor slab and coated with a waterproof coating layer.

[0009] Furthermore, the penetrating layer includes a gravel layer laid on the surface of the waterproof coating layer, and a sand and gravel layer laid on the surface of the gravel layer to fill the gaps inside the gravel layer.

[0010] Furthermore, the bottom surface of the tile is coated with tile adhesive, and a through hole is opened in the middle of the first filter screen, into which the drain pipe is inserted.

[0011] Furthermore, a threshold stone is fixedly connected to one side of the top of the floor slab. One side of the threshold stone is coated with a waterproof coating layer, and a water-stop strip is fixedly connected to one side of the threshold stone. The bottom end of the water-stop strip is fixedly connected to the surface of the tile.

[0012] Furthermore, a door track is fixedly connected to the top of the threshold stone, and a sliding door is slidably connected to the top of the door track.

[0013] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0014] With the setup of a first filter screen, a drain pipe, and a drain pipe, the first filter screen is fixedly connected to the top of the drain pipe during use, and the drain pipe is inserted into the middle of the first filter screen. Wastewater on the tile surface can flow into the drain pipe through the drain pipe, while water that flows into the waterproof layer surface through the tile gaps will flow into the drain pipe through the first filter screen. This achieves the effect of drainage on the waterproof layer surface without affecting the drainage of the tile surface, thus ensuring that no wastewater remains on the waterproof layer surface and improving the living environment.

[0015] By setting up a permeable layer, which includes a gravel layer and a sand layer, and laying the permeable layer between the cement mortar leveling layer and the waterproof coating layer, the sewage flowing in through the tile gaps can be discharged more easily, greatly improving drainage efficiency.

[0016] By installing a water-blocking strip, the strip is fixedly connected to the joint between the threshold stone and the tile, thereby preventing sewage from flowing into the waterproof layer through the joint between the tile and the threshold stone, thus improving the waterproofing effect.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] The present invention will be further described below with reference to the embodiments.

[0026] Example 1

[0027] Reference Figure 1-4 This is the first embodiment of the present utility model, which discloses an indoor waterproof structure, including: a floor slab 1, a waterproof layer 2 on the surface of the floor slab 1, a permeable layer 3 on the surface of the waterproof layer 2, a cement mortar leveling layer 4 on the top of the permeable layer 3, a ceramic tile 5 on the top of the cement mortar leveling layer 4, a drain pipe 6 fixedly connected to the bottom of the floor slab 1, a first filter screen 7 fixedly connected to the top of the drain pipe 6, a floor drain 8 on the top of the first filter screen 7, a drain pipe 9 fixedly connected to the bottom of the floor drain 8, and a second filter screen 10 snapped onto the top of the floor drain 8.

[0028] With the setup of the first filter screen 7, drain pipe 6, and drain pipe 9, the first filter screen 7 is fixedly connected to the top of the drain pipe 6 during use, and the drain pipe 9 is inserted into the middle of the first filter screen 7. Wastewater on the surface of the tile 5 can flow into the drain pipe 6 through the drain pipe 9, and water flowing into the surface of the waterproof layer 2 through the gaps in the tile 5 will flow into the drain pipe 6 through the first filter screen 7. Thus, the surface of the waterproof layer 2 can also drain simultaneously without affecting the drainage of the surface of the tile 5, thereby achieving the effect that no wastewater will remain on the surface of the waterproof layer 2, improving the living environment.

[0029] Example 2

[0030] Reference Figure 1-4 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0031] The waterproof layer 2 includes a ground slope layer 201, which is laid on the surface of the floor slab 1. The ground slope layer 201 is coated with a waterproof coating layer 202. The penetrating layer 3 includes a gravel layer 301, which is laid on the surface of the waterproof coating layer 202. A sand and gravel layer 302 is laid on the surface of the gravel layer 301, which is used to fill the gaps inside the gravel layer 301.

[0032] By setting up the permeable layer 3, which includes a gravel layer 301 and a sand and gravel layer 302, and laid between the cement mortar leveling layer 4 and the waterproof coating layer 202, the sewage flowing in through the gaps in the tiles 5 can be discharged more easily, greatly improving drainage efficiency.

[0033] The bottom surface of the tile 5 is coated with tile adhesive 501. The first filter screen 7 has a through hole in the middle. The drain pipe 9 is inserted into the through hole. A threshold stone 11 is fixedly connected to one side of the top of the floor slab 1. A waterproof coating layer 202 is applied to one side of the threshold stone 11. A water-blocking strip 12 is fixedly connected to one side of the threshold stone 11. The bottom end of the water-blocking strip 12 is fixedly connected to the surface of the tile 5. A door track 13 is fixedly connected to the top of the threshold stone 11. A sliding door 14 is slidably connected to the top of the door track 13.

[0034] By setting up the water-blocking strip 12, the water-blocking strip 12 is fixedly connected to the joint between the threshold stone 11 and the tile 5 during use, thereby preventing sewage from flowing into the waterproof layer 2 through the joint between the tile 5 and the threshold stone 11, thus improving the waterproof effect.

[0035] The remaining structure is the same as that in Example 1.

[0036] The working principle of this utility model is as follows:

[0037] First, before waterproofing construction, the surface of floor slab 1 must be treated. The surface of floor slab 1 must be cleaned to remove dust, oil and debris. Then, a ground slope layer 201 is laid with cement mortar. The lowest point of the ground slope layer 201 is located at the top of the drain pipe 6. Then, a layer of interface agent is applied to the surface of the ground slope layer 201 to enhance the adhesion between the ground slope layer 201 and the waterproof coating. The interface agent is an environmentally friendly emulsion interface agent, which has good penetration and adhesion and can penetrate into the pores of floor slab 1 to form a strong bonding layer. Then, the waterproof coating layer 202 is applied.

[0038] Secondly, a first filter screen 7 is fixedly installed at the top of the drain pipe 6, and then a gravel layer 301 is laid. Next, a sand and gravel layer 302 is laid on the surface of the gravel layer 301 to fill the gaps between the gravel. With the setting of the permeable layer 3, when in use, the permeable layer 3 includes the gravel layer 301 and the sand and gravel layer 302, and the permeable layer 3 is laid between the cement mortar leveling layer 4 and the waterproof coating layer 202, so that the sewage flowing in through the gaps of the tile 5 can be discharged more easily, which greatly improves the drainage efficiency.

[0039] Finally, cement mortar is used to level the surface of the sand and gravel layer 302 to form a cement mortar leveling layer 4. Then, tile adhesive 501 is applied to the back of the tile 5 and the tile 5 is laid on the surface of the cement mortar leveling layer 4. Then, the drain pipe 9 at the bottom of the floor drain 8 is inserted into the middle of the first filter screen 7. With the arrangement of the first filter screen 7, the drain pipe 6 and the drain pipe 9, the first filter screen 7 is fixedly connected to the top of the drain pipe 6 and the drain pipe 9 is inserted into the middle of the first filter screen 7. Sewage on the surface of the tile 5 can flow into the drain pipe 6 through the drain pipe 9, and water that flows into the surface of the waterproof layer 2 through the gaps in the tile 5 will flow into the drain pipe 6 through the first filter screen 7.

[0040] This allows the waterproof layer 2 to drain simultaneously without affecting the drainage of the tile 5 surface, thus preventing sewage residue on the waterproof layer 2 surface and improving the living environment. Then, the water-blocking strip 12 is fixed at the connection between the threshold stone 11 and the tile 5. With the water-blocking strip 12 in use, it is fixedly connected to the connection between the threshold stone 11 and the tile 5, thereby preventing sewage from flowing into the waterproof layer 2 through the joint between the tile 5 and the threshold stone 11, thus improving the waterproofing effect.

[0041] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
