Description

[Detailed explanation of the idea] [Industrial application field]

The present invention mainly relates to a drainage floor structure installed in a wash area of a bathroom on the second floor or above.

[Prior art and its problems]

Conventionally, a drainage device as shown in FIG. 3 has been used in the washing area of a bathroom. In this drainage device, a main body 30 is buried under the floor, and a drain pipe 20 with screws carved around it is raised and lowered to make the pipe opening 22 substantially flush with the floor surface 24, and waste water from the washing area floor is discharged from the pipe opening 22. This is how it was done. However, since this structure has a water-sealed trap inside the main body 30, drainage efficiency is not good, and when there is a lot of drainage, it temporarily accumulates near the drain outlet on the floor 24, making it unclean. . By the way, in Utility Model Application No. 59-70015, a drainage basin is proposed to be installed in the washing area of a bathroom to improve drainage efficiency. This drainage basin is constructed by attaching a floor trap to the drainage part at the bottom and burying it in the washing area floor. According to this, even when there is a lot of drainage,
Since the wastewater is temporarily collected in the drainage basin itself, it does not overflow into the washing area and does not become unclean. Also, during construction,
It also has the advantage of making it easier to slope the floor tiles and allowing the use of wider floor tiles. However, on the other hand, this drainage basin has a long boundary with the floor tiles, so there is a high possibility of water leaking from the boundary. Therefore, if the construction site is on the first floor, there is not much of a problem, but if the construction is to be carried out in a bathroom on the second floor or higher, if there is a leak, water will flow downstairs, so it is necessary to use the drainage basin mentioned above, where there is a high possibility of water leakage. A solution to this problem was desired during construction.

[Means to solve the problem]

The measures taken by the present invention to solve the above problems are as follows. That is, in the present invention, a drainage basin with a drain pipe facing downward is buried in the floor of the bathroom washing area, and a water collecting flange is installed on the outer periphery of the floor to collect leakage water. A water collection device equipped with a drainage trap device and a water-blocking member provided in layers are buried therein, and the water collection device communicates with the drain pipe, and the water-collection edge of the water-blocking member is buried. The section extends over the water collection flange to collect leakage water blocked by the water shielding member, and the side wall of the water collection device is further provided with a required number of communication lines leading from the water collection flange into the inside of the water collection device. This is a bathroom drainage floor structure with holes. Although a water-shielding sheet is normally used as the water-shielding member, other known water-shielding members may also be used. In the case of a water-shielding sheet, a through hole can be provided at the water collecting device, or the edge of the water-shielding sheet can be positioned. A perforated plate or mesh body for separating hair and the like is usually placed on the top of the drain pipe. The material of the water collecting device may be cast iron, plastic, etc., but is not particularly limited. The shape of the water collection flange of the water collection device is a disk shape with an inclined surface, but the shape is not particularly limited as long as it fulfills the function of collecting leakage water. The structure of the communication hole, such as a groove or a hole, is not particularly limited as long as it can discharge leakage water collected by the water collection flange into the water collection device main body.

【Example】

The present invention will be explained in more detail based on embodiments shown in the drawings. FIG. 1 is a sectional view showing an embodiment of the present invention. A water collection device 3 is buried in the concrete slab 50. A water-blocking sheet 51 is laid on the upper surface of the concrete slab 50. Penetration portions 510 are provided at predetermined locations on the water-blocking sheet 51. The concrete slab 50 at the peripheral edge of the penetrating portion 510 is formed to be slightly depressed, and the water-blocking sheet 51 is laid along it. The water collection tool 3 is disposed below the penetration part 510 of the water-blocking sheet 51, and the peripheral edge of the penetration part 510 is placed on the water collection flange 31 of the water collection tool 3. A base mortar 52 is placed on top of the water-shielding sheet 51. A drainage basin 1 is buried in the base mortar 52, and a drainage pipe 2 is attached to the drainage basin 1. Additionally, floor tiles 53 are stretched over the base mortar 52. FIG. 2 is an exploded perspective view of the drainage basin, drainage tube, and water collection device. The structures of the drainage basin, drainage tube, and water collection device will be explained with reference to FIGS. 1 and 2. The drainage basin 1 is a rectangular box in plan view with an open top, and includes a drainage basin body 11 and a lid 12. A required number of drainage holes 120 are formed in the lid 12 which is placed over the drainage basin body 11. Also, the drainage basin body 11
A circular drain port 15 is provided at one end of the bottom plate 13, and a flange portion 14 is provided at the inner edge of the drain port 15.
is formed. A drain pipe 2 of a predetermined length is attached to the flange portion 14, and a separation net 21 is placed on the upper part of the drain pipe 2. A water collection tool 3 is connected to the lower part of the drain pipe 2. The water collecting device 3 has an insertion portion 32 into which the drain tube 2 is inserted, formed at the upper part of a substantially bowl-shaped main body 30, and a gasket 35 is attached to an inner wall 33 of the insertion portion. Then, the drain tube 2 is inserted in a watertight state with a gasket 35. A disc-shaped water collection flange 31 is provided to surround this insertion portion 32. The insertion depth of the drain pipe 2 can be adjusted within a certain range, so that the drain basin main body 11 can be installed even on bathroom washroom floors of different heights. In addition, Patsukin 3
5 can also be attached to the drain pipe 2 side. An upper edge 34 is provided on the periphery of the insertion portion 32 to protrude upward, and a disc-shaped water collection flange 31 is formed slightly below the periphery of the upper edge 34. The peripheral edge of the water collection flange 31 is inclined upward,
This makes it easier to collect leakage water. Four communication holes 36 are formed between the upper surface of the water collection flange 31 and the upper edge 34 to communicate with the inside of the main body 30.
Leakage water collected by the water collection flange 31 is discharged into the main body 30. A cylindrical drainage part 37 is formed in the lower part of the main body 30 (Fig. 1), the upper part of the drainage part 37 protrudes upward from the bottom of the main body 30, the lower part protrudes downward, and a drainage pipe is provided on the inner wall of the lower part. An attaching portion 38 is formed to attach the. The upper part of the drainage part 37 is covered with a bowl body 39 having a placing part 390 inside to form a water-sealing type trap. According to this, when water leaks from the joints around the drainage basin main body 11 or the joints of the floor tiles 53, the leakage is stopped by the water-shielding sheet 51 and flows through the water-shielding sheet 51 to the water collection flange 31. Since the water is collected inside the water collecting device 3 through the communication hole 36, there is no need to worry about it leaking downstairs. Note that the present invention is not limited to the illustrated embodiment, and various modifications can be made within the scope of the claims of the utility model registration.

[Effects of the invention] The present invention has the above-mentioned configuration, and if this drainage floor structure is installed on the washing area floor of a bathroom, even if water leaks from the joints between the drainage basin and floor tiles, it will be prevented by the water-blocking material. Leakage water is collected and drained from the water collection device, so there is no need to worry about water leaking downward. Therefore, it is possible to construct drainage basins with high drainage efficiency, which previously had problems when installed in bathrooms on the second floor or above due to the risk of water leakage.
