Abstract

PURPOSE:To facilitate the piping work by forming an opening for work and inspection on the floor part of a bath tab installation part and so on having a stepped portion in its part so that it extends over a vertical surface and a horizontal surface and by blocking it with a freely removable lid body. CONSTITUTION:An opening 14 located in the neighborhood of the piping joint part 8 of a waterproof floor part 2 for a bath unit having a stepped portion 5a in its part is formed extending over a vertical surface 6 and a horizontal surface 5. A lid body 15 having a stepped portion is removably attached to the opening 14. And even if the depth of the stepped part 5a is small, the opening 14 which is sufficient for piping work is opened. By this process, the installation workability can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a waterproof floor for use in residential bath units.

BACKGROUND OF THE INVENTION Conventional waterproof floors of this type are shown in FIGS. 4 to 6. It is integrally molded with synthetic resin, and the standing walls 2a and 3a are on the outer periphery.
A waterproof floor part 2 having a water-proof base 2 and a waterproof washing base 3 are arranged side by side, and a bathtub l is installed on the waterproof floor part 2. Also,
A pipe connection part 8 consisting of a fitting such as a water faucet is installed on the horizontal surface 5 of a step part 5a integrally formed with the vertical wall 2a of the waterproof floor part 2, facing the bathtub flange part 1a of the bathtub l. This was done through the open lower inspection window provided on the vertical surface 6. 5 and 6 show details of the inspection window 7. FIG. For the faucet piping, a joint 8 is connected to a piping 13 on the horizontal surface 5 of the waterproof floor 2 with a packing 11 and a nut 12. This work is done through the inspection window 7, and the lid 9 shown in Fig.
0, it has a structure in which it is fixed to the vertical surface 6 of the step portion 5a.

Problems to be Solved by the Invention However, in the above conventional configuration, if the depth H of the vertical portion 6 of the stepped portion 5a depending on the vertical wall 2a of the waterproof floor portion 2 shown in FIG. However, if the depth H is small, it will be impossible to open a sufficient inspection window for the work due to conditions such as the space for tightening the screw 10 shown in Figure 5. It had drawbacks.

SUMMARY OF THE INVENTION An object of the present invention is to provide a waterproof floor that allows a sufficient inspection window for piping work even if the depth of the waterproof floor is reduced.

Means for Solving the Problems In order to achieve this object, the present invention provides an opening that serves as an inspection window for the stepped section provided in a part of the floor not only on the vertical surface of the stepped section but also on the vertical and horizontal surfaces. It is set up astride.

Effect: With the above configuration, an inspection window sufficient for work can be formed without being affected by the depth of the waterproof floor.

EXAMPLES Examples of the present invention will be described below with reference to FIGS. 1 to 3. Note that the same parts as those in the prior art are given the same reference numerals, detailed explanations are omitted, and different parts will be mainly explained. 14 is an opening that serves as an inspection window, and is located on the vertical surface 6 of the stepped portion 5a.
It opens across the horizontal plane [5]. The opening I4 is closed by forming the lid 15 into an L-shape as shown in FIG. 2 and attaching it to the vertical surface 6 and horizontal surface 5 of the stepped portion 5a with screws 10.

In the above embodiment, since the opening 14 is structured to span the vertical surface 6 and the horizontal surface 5 of the stepped portion 5a, the connection work portion of the pipe 13 to the joint 8 can be visually seen in the box shown in FIG. Furthermore, by making the lid 15 L-shaped, the strength of the lid 15 is increased, and when installing the lid 15, it becomes possible to place the L-shaped part on the horizontal surface 5 of the stepped part 5a, and tighten the screws. Work becomes easier.

Effects of the Invention As described above, the present invention facilitates piping work without being affected by the depth of the floor, and increases the strength of the lid and improves workability when attaching the lid. I can do it.
