Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention is used in the field of drainage equipment. More specifically, it is used in the field of bathroom drainage equipment.

The present invention relates to a drainage basin equipped with a depth adjustment frame.

[Prior art and its problems] Even when a trap is used, wastewater does not accumulate on the floor of the washing area, and a drainage basin that makes it easier to slope the washing area and use large tiles on the floor has been developed. No. 59-76688.

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 downstairs between the outer wall of the drainage basin and the concrete floor.

[Purpose of the invention]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a drainage basin that prevents water from leaking even when the drainage basin is buried in a washing area of a bathroom installed on the second floor or above of a building.

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

[Structure of the invention]

The present invention includes: a drainage basin main body having a discharge port and an open upper part; a depth adjustment frame fitted into the drainage basin main body so as to be movable up and down, and having a drainage inlet in the upper part; A water collection flange is formed at the periphery of the opening of the drainage basin body to receive water leakage, the depth adjustment frame has a peripheral wall, and the bottom part collects wastewater flowing from the inlet into the drainage basin body. A drainage hole is provided to allow water to flow into the drainage basin, and a water flow part 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 basin body. It is a drainage basin with a 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 then glued 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. You can also.

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

〔Example〕

The present invention will be explained in more detail based on embodiments 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 a metal plate, plastic, ceramics, etc., and is formed in the shape of a rectangular parallelepiped of a required length with an open top. At the periphery of the opening of the drainage basin main body 1, there is a water collection flange 11 that receives leakage water transmitted through the waterproof layer and guides it to the drainage basin main body 1.
is formed. 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 body 1 so as to be able to rise and fall freely.A flange 17 is formed around the inlet 16a to be positioned flush with the floor of the washing area, and the tip is folded downward. A curved 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 where the inflow from the inflow port 16a is formed. It serves as a drain port 16c through which wastewater flows into the drainage basin body 1. Then, when the depth adjustment frame 16 is fitted and installed in the drainage basin main body 1, the inner wall of the drainage basin main body 1 and the peripheral wall 16 of the depth adjustment frame 16
A water passage portion 20 is formed between the outer surface of b.

2 is a lid that is placed on the drainage basin body 1, and is made of a metal plate,
A supporting leg 21 made of plastic, ceramics, etc., whose upper surface of the lid 2 is approximately at the same height as the upper surface of the flange 17.
have. 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 drainage basin body 1, and a finger hook part 23 is formed on the edge for easy removal from the drainage basin body 1.

In the drainage basin according to this embodiment, the bottom plate 12 of the drainage basin main body 1 is sloped to make it easier for water to flow, so the upper surface of the drainage basin 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 drainage basin 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. Projection 1
It is also possible to make a groove by recessing the part 8.

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.

A drainage basin main body 1 is buried in a concrete floor C, and a waterproof layer S of coal tar or the like is formed on the floor C so as to overlap the protruding edge 110 of a water collection flange 11.

Floor concrete 30 is poured to a predetermined height on top of the waterproof layer S, and tiles T are attached via mortar M. At that time, the depth adjustment frame 16 is pulled up and the flange 17 is adjusted to be substantially the same as the tile T surface. For adjustment, if an arbitrary number of height adjustment devices 100 made of long nuts and bolts are interposed between the flange 17 and the water collection flange 11, the depth adjustment frame 16 will not move, making the work easier. Of course, other means can also be adopted.

The drainage basin installed in this way operates as follows.

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

〔Effect of the invention〕

The present invention provides a drainage basin main body having a discharge port and an open upper part; a depth adjustment frame fitted into the drainage basin main body so as to be movable up and down, and having a drainage inlet in the upper part; A water collection flange is formed around the opening of the drainage basin main body to receive water leakage, the depth adjustment frame has a peripheral wall, and the bottom part collects the drainage water flowing from the inflow port into the drainage basin. A drainage port is provided to drain the water into the main body, and a water passage is provided between the drainage basin main body and the depth adjustment frame to guide leakage water received at the water collection flange to the drainage basin main body. 1) When a drainage basin 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 drainage basin. Therefore, the drainage basin can be used without water leakage.

(2) Since the drainage basin itself is buried before the washing area floor is formed, if the thickness of the tiles or the thickness of the waterproof layer changes, the inlet may not be flush with the floor. However, in the present invention, the depth adjustment frame is fitted into the drainage basin body so that it can be raised and lowered, so even if the thickness of the tiles or the thickness of the waterproof layer changes slightly, the depth adjustment frame can be raised and lowered to drain water. The inlet can be adjusted so that it is flush with the washing area floor.
