BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof pan for bathrooms, toilets and washing machines, and more particularly to a waterproof pan having a level adjusting function.

[0002]

2. Description of the Related Art A conventional waterproof pan has a concrete
A support stand will be prepared on the ground such as G, a waterproof pan will be set on this, and a unit bath will be placed on this. However, usually the support base is equipped with multiple support legs, but if there is an uneven (uneven) part on the base, the support legs do not have an adjustment function, so it is possible to cut or fill the uneven part. It was carried out, and the plate for adjustment was pinched. In view of such a current situation, the inventors have conducted research on a waterproof pan that can be accompanied by uneven adjustment of the base,
We have prepared a support stand that can be adjusted separately from the waterproof pan, and we are studying the structure of the structure where the level of this support stand is adjusted and the waterproof pan is installed on it.

FIG. 3 is a side view showing a waterproof pan for a unit bath which has been developed and tested by the inventors in the course of research. In the figure, reference numeral 1 denotes a waterproof pan, and support bases 2 and 3 for the waterproof pan 1 are concrete bases 4.
It is installed on top. In the figure, the support base 2 may be a little shorter than the support base 3, and a unit bath (not shown) is arranged on the waterproof pan 1 on the support base 2 side. The waterproof pan 1 on the side serves as a washing area.

In order to set such a waterproof pan 1 on the concrete base 4, first, the support bases 2 and 3 are arranged on the concrete base 4 and the level 5 of which level can be adjusted.
The level will be adjusted with. In general, the support bases 2 and 3 are provided with 4 to 6 bolt-shaped legs 5, which are screwed together with nuts 6 attached to the support bases 2 and 3 to rotate the legs 5. Move it to match the level. In the figure, 7 is a drainage port for water flowing on the waterproof pan 1.

[0005]

[Problems to be Solved by the Invention] However, the waterproof pan 1
The following drawbacks have been pointed out in the method of disposing the support bases 2 and 3 which are separate from the above. That is, in addition to the waterproof pan 1, the cost increase due to the production of the separate support bases 2 and 3 naturally causes the occurrence of new work for transporting and storing the support bases 2 and 3.

Further, the size of the support bases 2 and 3 and the degree of level adjustment differ depending on the shape of the waterproof pan 1, and it is not always possible to manufacture only the support bases 2 and 3 in advance, and always. It has to be taken into consideration the compatibility with the waterproof pan 1, and it is manufactured in relatively small quantities, which also causes a cost increase.

Further, regarding the installation of the waterproof pan, since the waterproof pan is set on the support base, the height becomes relatively high. Therefore, if the height of the waterproof pan is regulated in order to secure the ceiling height above a certain level,
You may not be able to use this type of support,
There was also a problem that a support with a more special structure had to be provided.

The present invention has been made in view of the above situation, and an object thereof is to provide a waterproof pan which is low in cost and easy to install.

[0009]

That is, the structure of the present invention is as follows.
A waterproof pan provided on a concrete base, wherein the waterproof pan is provided with a through hole and an internal thread member fitted to the through hole, and the internal thread member is attached to the head for rotation. A male screw-shaped leg member having a joint is screwed,
The present invention relates to a waterproof pan having a level adjusting function, which is characterized in that a male screw-shaped leg member is rotated to adjust a level, and then a closing member is watertightly attached to the through hole from above the waterproof pan.

In the head portion of the leg member, one character groove or a cross groove is formed as a rotary engaging portion, and a driver or the like is inserted into the through hole of the waterproof pan, and the groove and the tip of the driver are inserted. The level of the leg member can be adjusted by engaging with and rotating this.

The closing member attached to the through hole is
It is necessary to make the water on the waterproof pan watertight so as not to leak, and in general, it is screwed and attached via an O-ring.

[0012]

Since the present invention adopts the above construction, the waterproof pan itself is provided with a level adjusting function, which can be adjusted on the waterproof pan. Therefore, it is not necessary to manufacture a support base separate from the waterproof pan, and the work of installing the waterproof pan can be performed quickly. Furthermore, the waterproof pan is ready for construction simply by placing it on the concrete base in advance, and the height of the waterproof pan can be adjusted as it is by adjusting the level of the leg members directly provided on the waterproof pan. In addition, since the worker can adjust the level while riding on the waterproof pan, the man-hours required for the work can be remarkably shortened.
