Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a drainage unit used to provide a drainage groove in the floor of a tiled bathroom, kitchen, or toilet.

[Prior art and its problems]

In this type of drainage unit, a stainless steel top cover with a number of through holes is removably placed over the top opening of a drainage box with a predetermined length and a drain port for connecting a drain pipe. (Utility Model Publication No. 59-76688, No. 60-186393, No. 61-15388)
(see issue).

By the way, when this drainage unit is installed as a drainage channel in a bathroom, it is desirable to bury the drainage box part so as to match the joints of tiles pasted on the floor of the bathroom. If both ends of the drain box are in conflict with the tile joints, the appearance of the bathroom floor will be impaired and the work of tiling around the drain box will be extremely troublesome.

Therefore, in conventional drainage units, the length of the drainage box is selected to be a predetermined length that corresponds to a multiple of the length of one side of the tile.

However, due to the plumbing of the drain pipe connected to the drainage box, there are cases where it is not possible to bury both ends of the drainage box in line with the tile joints. A drainage unit did not previously exist.

[Purpose of invention]

Therefore, the present invention provides a method for covering the top opening of the drainage box even when it is not possible to bury both ends of the drainage box so that they match the tile joints due to plumbing problems of the drainage pipe connected to the drainage box. To provide a drainage unit which can be installed by adjusting a part exposed on the floor surface such as a top cover to match tile joints.

[Structure of the idea]

In order to achieve this purpose, the present invention has a top opening of a drain box of a predetermined length, which is equipped with a drain port for connecting a drain pipe, and is removably covered with a top cover with a large number of through holes. In the drainage unit configured as above, the upper lid and a support frame to which the upper cover is removably fitted are formed to be shorter by a predetermined length than the length of the upper opening of the drainage box, and the support frame is connected to the upper opening of the drainage box. The support frame is movable along the length direction of the opening, and partition plates are provided at both front and rear ends of the support frame when viewed from the direction of movement, for partitioning the space inside the drainage box. .

[Effect of invention]

According to the present invention, the top cover and the support frame to which the top cover is removably fitted are formed to be shorter than the length of the top opening of the drain box, and are configured to be movable along the top opening. Therefore, even if it is not possible to bury the drain box in a position that coincides with the tile joints due to plumbing problems, the support frame with the top cover fitted can be moved along the length of the top opening of the drain box. By doing so, both front and rear ends or at least one end of the support frame can be aligned with the tile joint.

In this state, the space formed at both ends of the drainage box by the partition plates provided at both the front and rear ends of the support frame is filled with cement, etc., so that the support frame with the top lid fitted cannot be moved. Fix it.

As a result, the drainage unit is fixed with both ends of the support frame fitted with the top cover aligned with the tile joints, making tiling work easier. Since it is hidden under the tiles attached around the support frame, it does not spoil the appearance of the floor of the bathroom, etc.

〔Example〕

Hereinafter, embodiments of the present invention will be specifically described based on the drawings.

FIG. 1 is a perspective view showing an example of a drainage unit according to the present invention.

In the figure, 1 is a drainage box of a predetermined length provided with a drainage port 2 for connecting a drainage pipe, and the upper surface opening 3 of the drainage box 1 has a large number of through holes 4, 4.
An upper lid 5 having holes therein is configured to be removably covered.

This upper lid 5 has a top opening 3 of the drain box 1.
The support frame 6 is removably fitted to a support frame 6 which is arranged to move along the length of the support frame 6.

These upper lid 5 and support frame 6 are
It is formed to be shorter than the length of the upper surface opening 3 of the drainage box 1 by a predetermined length.

For example, when the length of the drainage box 1 is 750 mm, which corresponds to five 150 mm square tiles, the length of the support frame 6 is selected to be 600 mm, which is shorter by one tile. Note that the width of the support frame 6 is selected to be 150 mm, which is the same as the tile width.

Further, the support frame 6 that moves along the upper surface opening 3 of the drain box 1 is provided with partition plates 7 at both front and rear ends thereof, respectively, for partitioning the space inside the drain box 1 when viewed from the direction of movement.

The drainage box 1 is molded from synthetic resin and includes a support frame 6 and an upper lid 5 fitted onto the support frame 6.
are each made of stainless steel plate.

However, due to piping limitations of the drain pipe connected to the drain port 2 of the drain box 1, as shown in FIG. Even if the tile joint 10 cannot be buried, the support frame 6 fitted with the top cover 5 can be moved along the length direction of the top opening 3 of the drainage box 1, and both ends of the support frame 6 can be buried in line with the tile joint 10. match. At this time, since the support frame 6 can be moved by a distance corresponding to the length of one tile at most, the tile joint 10
can be reliably matched.

In this state, spaces 11 formed between the partition plates 7 formed at both ends of the support frame 6 and both ends of the drainage box 1 are filled with cement 12, etc., and the support frame 6 is closed. At the same time as fixing it, tiles 9 are pasted around it. On this occasion,
Since both ends of the support frame 6 are aligned with the tile joints 10, it is extremely easy to attach the tiles 9 to the corresponding parts.

As shown in FIG. 3, the drainage unit installed in this manner has a support frame 6 fitted with a top cover 5, with both ends of the support frame 6 completely aligned with the tile joints 10. Since the entire drainage box 1 is completely hidden by the top cover 5, support frame 6 and tiles 9, the construction finish is very neat and looks good.

Further, since the drainage box 1 is completely hidden, there is no need to manufacture the drainage box 1 from expensive stainless steel plate or the like as in the past, and it may be integrally molded from an inexpensive synthetic resin as in the embodiment.

As shown in FIG. 4, the drain port 2 is provided so as to be movable in the width direction of the drain box 1 as shown by the chain line, and the support frame 6 is attached to the drain box 1 relative to the drain port 2. By making it movable in a direction perpendicular to the movement direction as shown by the chain line, it is also possible to adjust the front, rear, left and right sides of the support frame 6 to perfectly match the vertical and horizontal tile joints.

That is, a relatively large-diameter hole 13 is bored in the bottom of the drain box 1 into which the drain port 2 with a drain trap is loosely inserted, and the drain box 1 is inserted into the drain port 2.
It can be moved relative to the direction perpendicular to the moving direction of the support frame 6 while slidingly contacting the lower surface of the brim-like flange 2a formed at the upper end. After the drain box 1 is moved to match the tile joints in this manner, the brim-like flange 2a of the drain port 2 is adhered and fixed to the bottom of the drain box 1.

In addition, in the embodiment, a case has been described in which the drainage box 1 is molded from synthetic resin, but the present invention is not limited to this, and may be molded from a stainless steel plate as in the conventional case.

Furthermore, the drainage unit according to the present invention is not limited to being used in bathrooms, but can also be used on the floors of kitchens and toilets in restaurants, for example.

[Effect of idea]

As mentioned above, the drainage unit according to the present invention can be used in cases where the drainage box cannot be buried in line with the joints of tiles pasted on the floor of a bathroom, etc. due to the plumbing of the drainage pipe connected to the drainage box. Even if the top cover is fitted, both ends or at least one end of the support frame is fixed in line with the tile joints, and the tiles are pasted around it, making the tiling work extremely easy. Since both ends of the drainage box buried in conflict with the joint are hidden under the tiles pasted around the support frame, it has an excellent effect of not spoiling the appearance of the floor surface of the bathroom or the like.
