Description

Technical Field

[0001] The present invention relates to a waterproofing system and construction method for a bathroom, belonging to the technical field of bathroom waterproofing. Background Art

[0002] The bathroom is a space area with a relatively large amount of water used in people's living or working places. In order to reduce water seepage and leakage during the use of the bathroom, resulting in water accumulation in the bathroom and even affecting the normal use of other space areas.

[0003] Currently, waterproofing construction is carried out on the bathroom during the construction or renovation of the bathroom. In the related art, generally, a waterproof coating is first applied to the lower part of the rough wall surface and the floor of the completed bathroom, and then a water test is carried out. After the test is qualified, decorative materials with a certain waterproof performance such as tiles are then pasted on the floor and wall, thus completing the bathroom waterproofing construction.

[0004] However, the current bathroom waterproofing systems on the market have poor effects and are very prone to ground seepage, resulting in damage and leakage of the ceiling of the lower floor, thus affecting the normal life of residents.

[0005] Therefore, a new solution is needed to solve this problem. Summary of the Invention

[0006] The technical problem to be solved by the present invention is as follows: to provide a waterproofing system and construction method for a bathroom, which solves the problem that the current bathroom waterproofing systems on the market have poor effects and are very prone to ground seepage, resulting in damage and leakage of the ceiling of the lower floor, thus affecting the normal life of residents.

[0007] The technical problem to be solved by the present invention is achieved by adopting the following technical solutions: a waterproofing system for a bathroom, including a floor, a water passing port is provided on the floor, a floor drain is arranged in the water passing port, the floor includes a base layer, a waterproof layer, a sand cushion layer and a surface layer laid in sequence from bottom to top, the surface layer is formed by laying a plurality of floor tiles, adjacent floor tiles are connected by a connecting structure, the connecting structure includes a connecting plate, connecting blocks are arranged at both bottom sides of the connecting plate, mounting plates are arranged around the floor tiles, convex plates are arranged at the top of the side of the mounting plate away from the floor tile, and a sealing cavity for injecting sealant is formed between the connecting block and the floor tile.

[0008] By adopting the above technical solution, since the floor includes a base layer, a waterproof layer, a cushion sand layer and a surface layer laid in sequence from bottom to top, and the surface layer is formed by laying a plurality of floor tiles, and adjacent floor tiles are connected by a connecting structure, when laying the floor tiles, only the connecting plate needs to be placed on the convex plate of the adjacent floor tile, so that the connecting block enters between the convex plate and the side wall of the floor tile, and the convex plate enters between the two connecting blocks, thereby making it difficult for water to overflow from the gap between the connecting block and the convex plate and flow into the cushion sand layer, improving the waterproof effect of the surface layer. And because a sealing cavity is formed between the connecting block and the floor tile, by injecting sealant into the sealing cavity, not only can the connecting plate be connected to the floor tile, but also the gap between the connecting plate and the floor tile can be filled, greatly improving the sealing performance, thus making it difficult for the ground to seep water, avoiding damage and water leakage of the ceiling of the lower floor house, and ensuring the normal life of residents.

[0009] The present invention is further configured such that: a water-absorbing and expanding rubber is provided between the convex plates of adjacent floor tiles.

[0010] By adopting the above technical solution, since a water-absorbing and expanding rubber is provided between the convex plates of adjacent floor tiles, when water overflows from the gap between the connecting block and the convex plate and enters the gap between the connected convex plates, the water-absorbing and expanding rubber will absorb water and expand. On the one hand, it can fill the gap between adjacent convex plates, and on the other hand, it can also lift the connecting plate, enabling people to notice the bulge of the connecting plate, thereby noticing the water leakage here and urging people to repair the surface layer, effectively playing a warning role.

[0011] The present invention is further configured such that: the opposite surfaces of the connecting block and the convex plate are both inclined.

[0012] By adopting the above technical solution, since the opposite surfaces of the connecting block and the convex plate are both inclined, when the water-absorbing and expanding rubber expands, it can not only apply an upward force to the connecting plate, but also apply a force to both sides, so that the convex plates tend to move away from each other. Thus, under the guiding action of the inclined connecting block and convex plate, the connecting plate can bulge more easily, making the warning effect of the connecting plate more obvious.

[0013] The present invention is further configured such that: a plurality of drainage pipes with a semicircular cross-section are provided and interconnected at positions between adjacent floor tile gaps in the cushion sand layer, and a water pipe communicating with the plurality of drainage pipes is further provided on the cushion sand layer, and one end of the water pipe communicates with a water passing port.

[0014] By adopting the above technical solution, since a plurality of drainage pipes with a semicircular cross-section are provided and interconnected at positions between adjacent floor tile gaps in the cushion sand layer, when water flows over the water-absorbing and expanding rubber and enters the cushion sand layer, it can enter the drainage pipes, and the water accumulated in the drainage pipes will flow into the water passing port through the water pipe, thereby improving the drainage capacity of the bathroom and further enhancing the waterproof effect of the bathroom.

[0015] The present invention is further configured such that: two clamping plates for clamping into the water passing port are oppositely arranged at the bottom of the floor drain, and clamping blocks with a trapezoidal cross-section are arranged on the outer walls of the clamping plates.

[0016] By adopting the above technical solution, since two clamping plates are arranged at the bottom of the floor drain and clamping blocks are arranged on the outer walls of the clamping plates, the clamping plates can enable the floor drain to be clamped into the water passing port and not easy to shake. The arrangement of the clamping blocks can effectively improve the connection strength of the floor drain, making the floor drain not easy to break away from the water passing port and achieving a better filtering effect. Since the cross-section of the clamping block is trapezoidal, that is, both the upper and lower ends are inclined, through the guiding effect of the inclined surface, when the clamping plate is clamped into the water passing port, the two clamping blocks will first approach each other to meet the diameter at the installation opening of the floor drain, and then return to their original state and abut against the inner wall of the water passing port after being clamped into the water passing port.

[0017] The present invention is further configured such that: convex blocks are arranged on the surface of the floor drain, and a groove for the convex blocks to be clamped into is formed on the surface of one floor tile.

[0018] By adopting the above technical solution, since convex blocks are arranged on the surface of the floor drain and a groove for the convex blocks to be clamped into is formed on the surface of one floor tile, after the convex blocks are clamped into the groove, the groove limits the convex blocks, making the floor drain not easy to shake and achieving a positioning effect.

[0019] The present invention is further configured such that: a water inlet is formed on one of the clamping blocks, and one end of the water passing pipe inclines downward and is communicated with the water inlet.

[0020] By adopting the above technical solution, since a water inlet is formed on one of the clamping blocks and one end of the water passing pipe inclines downward and is communicated with the water inlet, when the convex block is clamped into the groove, the water inlet on the clamping block is just communicated with the end of the water passing pipe, so that the leaked water can flow into the water passing port through the water inlet and be discharged.

[0021] The present invention is further configured such that: a waterproof coiled material is also laid between the waterproof layer and the sand cushion layer, and the waterproof layer is composed of a plurality of polypropylene fabrics stacked and laid.

[0022] By adopting the above technical solution, since a waterproof coiled material is also laid between the waterproof layer and the sand cushion layer and the waterproof layer is composed of a plurality of polypropylene fabrics stacked and laid, the laying of the waterproof coiled material greatly improves the waterproof effect of the bathroom floor. The polypropylene fabric has excellent hydrophobicity, making the bathroom more difficult to leak.

[0023] A construction method of a waterproof system for a bathroom, characterized by comprising the following steps:

[0024] Step 1, clean the bottom plate of the bathroom and sweep away the dust;

[0025] Step 2: Subbase construction. Reserve the position for the drain pipe, and then evenly lay cement on the bathroom floor slab to complete the subbase laying.

[0026] Step 3: Waterproof layer laying. Evenly lay and stack several polypropylene fabrics on the surface of the subbase to form a waterproof layer.

[0027] Step 4: Lay waterproof coiled materials on the surface of the waterproof layer, and use edge pressing treatment between adjacent waterproof coiled materials.

[0028] Step 5: Bedding sand layer laying. Reserve grooves for the drainage pipe and the water pipe on the surface of the bedding sand layer, and place the drainage pipe and the water pipe.

[0029] Step 6: Floor tile paving. Evenly lay several floor tiles on the surface of the bedding sand layer according to the contour position formed by the drainage pipe. Then place the water-absorbing and expanding rubber between the adjacent convex plates. Then connect the adjacent floor tiles through the connecting plate, and apply sealant on the sealing cavity of the floor tile. Then snap in the floor drain so that the convex block snaps into the groove, and connect the water inlet with one end of the water pipe to complete the waterproof construction of the bathroom.

[0030] The beneficial effects of the present invention are as follows: Since the floor includes a subbase, a waterproof layer, a bedding sand layer and a surface layer laid in sequence from bottom to top, and the surface layer is composed of several floor tiles laid, and the adjacent floor tiles are connected by a connecting structure, when laying the floor tiles, only need to place the connecting plate on the convex plate of the adjacent floor tiles, so that the connecting block enters between the convex plate and the side wall of the floor tile, and the convex plate enters between the two connecting blocks, so that the water flow is not easy to overflow from the gap between the connecting block and the convex plate and flow into the bedding sand layer, improving the waterproof effect of the surface layer. And because a sealing cavity is formed between the connecting block and the floor tile, by injecting sealant into the sealing cavity, not only can the connecting plate be connected with the floor tile, but also the gap between the connecting plate and the floor tile can be filled, greatly improving the sealing performance, so that it is not easy to cause ground water seepage, avoiding damage and water leakage of the ceiling of the lower floor house, and ensuring the normal life of residents.

Specific embodiments

[0037] In order to clearly understand the technical means, creative features, achieved purposes and effects of the present invention, the present invention will be further described below with reference to specific drawings.

[0038] As Figures 1 to 3 shown, a waterproof system for a bathroom includes a floor, a water inlet 1 is opened on the floor, a floor drain 2 is arranged in the water inlet 1, the floor includes a base layer 3, a waterproof layer 4, a sand cushion layer 5 and a surface layer 6 which are sequentially laid from bottom to top, a waterproof coiled material 21 is also laid between the waterproof layer 4 and the sand cushion layer 5, the waterproof layer 4 is composed of a plurality of polypropylene fabrics stacked and laid, the surface layer 6 is composed of a plurality of floor tiles 7 laid, adjacent floor tiles 7 are connected by a connecting structure, the connecting structure includes a connecting plate 8, connecting blocks 9 are arranged at the bottoms of both sides of the connecting plate 8, mounting plates 10 are arranged around the floor tiles 7, convex plates 11 are arranged at the tops of the sides of the mounting plates 10 away from the floor tiles 7, a sealing cavity 12 for pouring sealant is formed between the connecting blocks 9 and the floor tiles 7, and the opposite surfaces of the connecting blocks 9 and the convex plates 11 are both inclined.

[0039] As Figure 3 shown, water swellable rubber 13 is arranged between the convex plates 11 of adjacent floor tiles 7, a plurality of drainage pipes 14 with semicircular cross-sections are arranged and communicated with each other at the positions of the sand cushion layer 5 between the gaps of adjacent floor tiles 7, a water pipe 15 communicated with the plurality of drainage pipes 14 is also arranged on the sand cushion layer 5, and one end of the water pipe 15 is communicated with the water inlet 1.

[0040] As Figure 1 , Figure 4 and Figure 5 shown, two clamping plates 16 for clamping into the water inlet 1 are oppositely arranged at the bottom of the floor drain 2, clamping blocks 17 with trapezoidal cross-sections are arranged on the outer walls of the clamping plates 16, a convex block 18 is arranged on the surface of the floor drain 2, a groove 19 for the convex block 18 to be clamped into is opened on the surface of one floor tile 7, a water inlet 20 is opened on one clamping block 17, and one end of the water pipe 15 is inclined downward and communicated with the water inlet 20.

[0041] Since the floor includes a base layer 3, a waterproof layer 4, a cushion sand layer 5, and a surface layer 6 laid in sequence from bottom to top, and the surface layer 6 is composed of a number of floor tiles 7, and adjacent floor tiles 7 are connected by a connection structure. When laying the floor tiles 7, only need to place the connecting plate 8 on the convex plate 11 of the adjacent floor tiles 7, so that the connecting block 9 enters the gap between the convex plate 11 and the side wall of the floor tile 7, and the convex plate 11 enters the gap between the two connecting blocks 9. Thus, it is not easy for water to overflow from the gap between the connecting block 9 and the convex plate 11 and flow into the cushion sand layer 5, improving the waterproof effect of the surface layer 6. And because a sealing cavity 12 is formed between the connecting block 9 and the floor tile 7, by injecting sealant into the sealing cavity 12, not only can the connecting plate 8 be connected to the floor tile 7, but also the gap between the connecting plate 8 and the floor tile 7 can be filled, greatly improving the sealing performance, thus not easily causing ground water seepage, avoiding damage and water leakage of the ceiling of the lower floor house, and ensuring the normal life of residents.

[0042] Since a water-absorbing and expanding rubber 13 is provided between the convex plates 11 of adjacent floor tiles 7, when water overflows from the gap between the connecting block 9 and the convex plate 11 and enters the gap between the connected convex plates 11, the water-absorbing and expanding rubber 13 will absorb water and expand. On the one hand, it can fill the gap between adjacent convex plates 11, and on the other hand, it can also lift the connecting plate 8, enabling people to notice the bulge of the connecting plate 8, thus noticing the water leakage here and urging people to repair the surface layer 6, effectively playing a warning role.

[0043] Since the opposite sides of the connecting block 9 and the convex plate 11 are both inclined, when the water-absorbing and expanding rubber 13 expands, it can not only apply an upward force to the connecting plate 8, but also apply forces to both sides, so that the convex plates 11 tend to move away from each other. Thus, under the guiding action of the inclined connecting block 9 and convex plate 11, the connecting plate 8 can bulge more easily, making the warning effect of the connecting plate 8 more obvious.

[0044] Since a number of drainage pipes 14 with semicircular cross-sections are provided and interconnected at the positions between adjacent floor tiles 7 in the cushion sand layer 5, when water flows over the water-absorbing and expanding rubber 13 and enters the cushion sand layer 5, it can enter the drainage pipes 14, and the water accumulated in the drainage pipes 14 will flow into the water through-hole 1 through the water pipe 15, thus improving the drainage capacity of the bathroom and further enhancing the waterproof effect of the bathroom.

[0045] Since there are two clamping plates 16 provided at the bottom of the floor drain 2, and clamping blocks 17 are provided on the outer walls of the clamping plates 16, the clamping plates 16 can make the floor drain 2 be clamped into the water inlet 1 and not easy to shake. The clamping blocks 17 can effectively improve the connection strength of the floor drain 2, making the floor drain 2 not easy to break away from the water inlet 1, and achieving a better filtering effect. Since the cross-section of the clamping block 17 is trapezoidal, that is, both the upper and lower ends are inclined, through the guiding function of the inclined surface, when the clamping plate 16 is clamped into the water inlet 1, the two clamping blocks 17 will first approach each other to meet the diameter at the installation opening of the floor drain 2, and then return to their original state and abut against the inner wall of the water inlet 1 after being clamped into the water inlet 1.

[0046] Since there are convex blocks 18 provided on the surface of the floor drain 2, and a groove 19 for the convex blocks 18 to be clamped into is provided on the surface of one floor tile 7, through the limitation of the convex blocks 18 by the groove 19 after the convex blocks 18 are clamped into the groove 19, the floor drain 2 is not easy to shake and achieves a positioning effect.

[0047] Since a water inlet 20 is provided on one clamping block 17, and one end of the water pipe 15 inclines downward and is communicated with the water inlet 20, when the convex block 18 is clamped into the groove 19, the water inlet 20 on the clamping block 17 is just communicated with the end of the water pipe 15, so that the leaked water can flow into the water inlet 1 through the water inlet 20 and be discharged.

[0048] Since a waterproof coiled material 21 is also laid between the waterproof layer 4 and the sand cushion layer 5, and the waterproof layer 4 is composed of a plurality of polypropylene fabrics stacked and laid, the laying of the waterproof coiled material 21 greatly improves the waterproof effect of the bathroom floor. The polypropylene fabric has excellent hydrophobicity, making the bathroom less likely to leak.

[0049] A construction method of a waterproof system for a bathroom includes the following steps:

[0050] Step 1: Clean the bottom plate of the bathroom and sweep away the dust;

[0051] Step 2: Construct the base layer 3, reserve the position of the drain pipe, and then evenly lay cement on the bottom plate of the bathroom to complete the laying of the base layer 3;

[0052] Step 3: Lay the waterproof layer 4, evenly lay and stack a plurality of polypropylene fabrics on the surface of the base layer 3 to form the waterproof layer 4;

[0053] Step 4: Lay the waterproof coiled material 21 on the surface of the waterproof layer 4, and perform edge pressing treatment between adjacent waterproof coiled materials 21;

[0054] Step 5: Lay the sand cushion layer 5, and reserve grooves 19 for the drain pipe 14 and the water pipe 15 on the surface of the sand cushion layer 5 and place the drain pipe 14 and the water pipe 15;

[0055] Step 6: Laying floor tiles 7. Lay a number of floor tiles 7 evenly on the surface of the bedding sand layer 5 according to the contour position formed by the drainage pipe 14. Then place the water-absorbing and expanding rubber 13 between the adjacent convex plates 11. Then connect the adjacent floor tiles 7 through the connecting plate 8, and apply sealant on the sealing cavity 12 of the floor tiles 7. Then snap in the floor drain 2 so that the convex block 18 snaps into the groove 19, and connect the water inlet 20 with one end of the water pipe 15, thus completing the waterproof construction of the bathroom.
