The following problems arise when installing this drainage basin in the washing area of a bathroom located on the second floor or higher of a multi-story building.

In other words, in bathrooms installed on the second floor or higher of a building, a waterproof layer is formed on the concrete floor to prevent water from leaking downstairs, and water that leaks from between the tiles is stopped by the waterproof layer. (See Figure 3).

However, if the above-mentioned drainage basin is buried in the floor as it is, there is a risk that water leaking between the tiles, etc. will flow through the waterproof layer and leak down the floor between the outer wall of the drainage basin and the concrete floor.

[Object of the Invention] Therefore, the object of the present invention is to provide a drainage basin that prevents water from leaking even when the drainage basin is buried in the washing area of a bathroom installed on the second floor or above of a building. be.

Another object of the present invention is to provide a drainage basin that can be adjusted so that the drainage inlet and the washing base surface are flush even if the thickness of the tiles or the thickness of the waterproof layer changes slightly. It is about providing.

[Structure of the Invention] The present invention comprises: a drainage basin main body having a discharge port and an open upper part; a depth adjustment frame; a water collection flange for receiving water leakage is formed around the opening of the drainage basin body; the depth adjustment frame has a peripheral wall; A drainage port is provided to allow the drained water to flow into the drainage basin body, and a water passage portion is provided between the drainage basin body and the depth adjustment frame to guide leakage water received at the water collection flange into the drainage powder body. This is a drainage basin with a depth adjustment frame.

The shape of the drainage basin can be, for example, a square or a rectangle in plan view.

The trap can be made separately from the drainage basin and attached to the drain outlet of the drainage basin itself, or the trap case can be integrally molded into the drainage basin body and the trap body can be built into it. It can also be done.

The water passage portion is formed by a gap provided between the drainage basin main body and the depth adjustment frame, but a groove may be provided instead of the gap. The point is that the water passage part is where leakage water flowing from the water collection flange flows into the wastewater powder body.

[Example] The present invention will be described in more detail based on an example shown in the drawings. FIG. 1 is an exploded perspective view showing a first embodiment.

Reference numeral 1 denotes the main body of the drainage basin, which is made of metal plate, plastic, ceramics, etc., and is formed in the shape of a rectangular parallelepiped of a required length with an open top. A water collection flange 11 is formed on the periphery of the opening of the drainage basin body 1 to receive leakage water leaking through the waterproof layer and guide it to the drainage basin body 1. The edge of the water collecting flange 11 is bent upward to form a protruding edge 110.

The bottom plate 12 of the drainage basin body 1 is sloped from one side to the other in the length direction, and a drain port 13 is formed at the sloped end. The drain port 13 is equipped with a trap 3.

An arbitrary number of protrusions 15 are formed on the inner surface of the side wall of the drainage basin main body 1 in the height direction. The protrusions 15 can also be recessed to form grooves.

The depth adjustment frame 16 is fitted into the drainage basin main body 1 so as to be able to rise and fall freely, and a flange 17 is formed around the inlet 16a to be positioned on the same plane as the floor of the washing area. A bent portion 170 is provided. The outer shape of the peripheral wall 16b of the depth adjustment frame 16 is formed so that it can be fitted into the drainage basin body 1 somewhat tightly. The lower edge of the depth adjustment frame 16 is bent inward to form a stepped portion 19 on which the support leg 21 of the lid 2 is placed, and the area surrounded by the stepped portion 19 is located at the inlet port 1.
It serves as a drain port 16c through which the wastewater flowing in from 8a flows into the drainage basin body 1. When the depth adjustment frame 16 is fitted and installed in the drainage basin main body 1, a water passage portion 20 is formed between the inner wall of the drainage powder main body 1 and the outer surface of the peripheral wall 16b of the depth adjustment frame 16.

Reference numeral 2 denotes a lid that is placed over the wastewater powder main body 1, and is made of a metal plate, plastic, ceramics, etc., and has a supporting leg 21 whose upper surface M2 is at the same height as the upper surface of the flange 17. The lid 2 is fitted into the adjustment frame 16. The lid 2 can also be shaped like a flat plate, in which case the stepped portion 19 is formed at the periphery of the inlet 16a. A required number of drainage holes 22 are formed in the lid 2 to allow drainage to flow into the drained powder body 1, and a finger hook 23 is formed on the edge for easy removal from the drained powder body 1.

In the drainage powder according to this embodiment, the bottom plate 12 of the drainage powder main body 1 is sloped to facilitate water flow, so the top surface of the drainage powder main body 1 can be installed parallel to the floor of the washing area, and construction work is easy. Easy to do.

FIG. 2 is an exploded perspective view showing a second embodiment of the present invention without a lid.

In this embodiment, the inner surface of the side wall of the drained powder main body 1 is a smooth surface, and an arbitrary number of protrusions 18 are formed on the outer surface of the peripheral wall 16b of the depth adjustment frame 16 in the height direction. The protrusions 18 can also be recessed to form grooves.

Note that the same or equivalent parts as in the first embodiment are indicated by the same reference numerals.

Next, the installation method and operation will be explained with reference to FIG.

■ Bury the drainage powder body 1 in the concrete floor C so that it overlaps the flange 110 of the water collection flange 11,
A waterproof layer S of coal tar or the like is formed on the floor C.

- Floor concrete 30 is poured to a predetermined height on top of the waterproof layer S, and tiles T are pasted through mortar M. At that time, the depth adjustment frame 16 is pulled up and adjusted so that the flange 17 is located between the surface of the tile and the road. For adjustment, for example, a height adjustment device 100 consisting of a long nut and bolt is used.
By interposing an arbitrary number of holes between the flange 17 and the water collection flange 11, the depth adjustment frame 16 does not move, making the construction work easier. Of course, other means can also be adopted.

The drainage powder installed in this way acts as follows.

When drainage water from the washing base floor or the like leaks from between the tiles T, etc., the leakage water is stopped by the waterproof layer S and flows toward the drainage powder main body 1. The leaked water is received by the water collection flange 11 and flows over it, flows into the drainage powder body 1 from the water passage part 20 between the drainage powder body 1 and the depth adjustment frame 16, and is drained from the drain port 13. It flows into trap 3 and is drained.

[Effects of the Invention] The present invention comprises a wastewater powder main body having a discharge port and an open upper part; A water collection flange is formed around the opening of the drainage powder main body to receive water leakage, and the depth adjustment frame has a peripheral wall, and a bottom portion is provided with a water collection flange for receiving water leakage, and a bottom portion is provided with a water collection flange for receiving water leakage. A drain port is provided to allow the drained water to flow into the wastewater powder body, and further, a water passage portion is provided between the wastewater powder body and the depth adjustment frame to guide leakage water received at the water collection flange into the wastewater powder body. (1) If wastewater powder is buried in the washing area of a bathroom installed on the second floor or above of a building, leakage water from the waterproof layer can be reliably flushed into the wastewater powder. . Therefore, drainage powder can be used without water leakage.

(2) Since the main body of the waste water powder is buried before the washing base surface is formed, if the thickness of the tile or the thickness of the waterproof layer changes, there will be an inconvenience that the inlet will not be flush with the floor surface. However, in the present invention, the depth adjustment frame is fitted into the drainage powder main body so that it can be raised and lowered, so even if the thickness of the tile or the thickness of the waterproof layer changes slightly, the depth adjustment frame can be raised and lowered to drain water. It can be adjusted so that the inlet and the washing base surface are flush with each other.
