Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a waterproof floor pan used in a unit room of a unit bath, and more specifically, to the waterproof floor pan with an improved drain pipe mounting structure.

[Prior art] In unit rooms such as unit baths,
One-piece waterproof floor pans made of FRP (glass fiber reinforced resin) are widely used.

FIG. 2 is a plan view showing an example of the shape of a waterproof floor pan for a unit bath, and FIG. 3 is a sectional view taken along the line shown in FIG. 2. This waterproof floor pan 1 is provided with a drain port 2, and a drain pipe 3 is connected to the drain port 2 and is attached along the back surface of the floor pan 1. On the back surface of the floor pan 1, in addition to legs 4 for installing the floor pan 1, a suitable number of reinforcing ribs 5 are integrally formed.

The drain pipe 3 is attached to this reinforcing rib 5 via a fitting. FIGS. 4 and 5 are a sectional view and a perspective view showing a conventional structure for attaching a drain pipe to a rib. As shown, rib 5
A drain pipe 3 is attached to the drain pipe 3 by a pipe fixing fitting consisting of a pedestal portion 6 and a saddle band 7.
The pedestal part 6 has a bolt 8a and a nut 8b attached to the rib 5.
The saddle band 7 is arranged so as to enclose the drain pipe 3, and is attached to the pedestal part 6 with screws 9.

[Problems to be Solved by the Invention] It is important that the drain pipe of the waterproof floor pan is installed correctly so that it has a certain slope so that drainage can flow smoothly. However, in the above-mentioned conventional mounting structure, a pipe fixing fitting consisting of a pedestal portion 6 and a saddle band 7 is used, and it is extremely difficult to tilt the pipe 3. That is, the pedestal part 6
To attach the rib 5 to the rib 5, a bolt insertion hole is opened in the rib 5, and the bolt 8a is inserted into the bolt insertion hole of the pedestal part 6 and the bolt insertion hole of the rib 5 and tightened. If the opening position of the insertion hole is shifted even slightly in the vertical direction, the mounting height of the pipe 3 will immediately change, resulting in a deviation from the designed slope. Therefore,
Bolt insertion holes had to be formed in the ribs 5 with high precision, making the work unnecessarily difficult.

Furthermore, in the conventional mounting structure described above, two metal fittings (the pedestal part and the saddle band) are used as pipe fixing fittings, so it takes a lot of time and effort to tighten them, and the work takes a long time.

[Means for solving the problem] The waterproof floor pan of the present invention has a drain pipe mounting part for attaching a drain pipe integrated with a reinforcing rib at a height that is aligned with the slope of the drain pipe installation. The drain pipe is fixed by coming into contact with the drain pipe mounting portion.

[Function] With this configuration, the drain pipe can be correctly installed at the designed slope. Since this drain pipe attachment part is integrally molded when manufacturing the waterproof floor pan, it is made to the same height as the molding mold and is formed with high precision. Since the drain pipe is disposed in contact with the drain pipe attachment portion, it is possible to reliably obtain the correct inclination as designed. According to the present invention, only one metal fitting is required when installing the drain pipe, and the effort required during installation is greatly simplified.

[Examples] The present invention will be described in more detail below with reference to embodiments shown in the drawings.

FIG. 1 is a front view showing the structure of a drain pipe attachment part of a waterproof floor pan according to an embodiment of the present invention, and FIG. 6 is a sectional view thereof. In FIG. 1, a drain pipe attachment part 10 is formed integrally with the rib 5,
A drain pipe 3 is disposed in contact with the lower side 10a of this attachment portion 10. Reference numeral 11 denotes a saddle band, which has a U-shape, and its base end 11a is fixed to the mounting portion 10 with bolts 8a and nuts 8b.

This mounting part 10 is molded integrally with the rib 5, and has a height that matches the dimensions of the mold for forming the waterproof floor pan, so that its lower side 10a forms the correct slope of the drain pipe. It has the height as designed for this purpose. Since the drain pipe 3 is immediately brought into contact with the lower side 10a of the mounting portion 10, the inclination of the drain pipe is as designed, allowing smooth drainage flow.

In addition, the saddle band 11 is the only metal fitting for fixing the drain pipe 3, and a pedestal part is not required as in the conventional case, so it is possible to obtain effects such as a reduction in the number of parts and a reduction in the number of tightening man-hours.

FIG. 7 is a front view of a drain pipe attachment part for explaining a different embodiment of the present invention. In FIG. 7, a recess 10b for positioning the drain pipe is formed in the lower side 10a of the drain pipe mounting portion 10, and the structure is configured so that the drain pipe can be easily positioned in the left and right direction when installing the drain pipe. has been done.

In the above embodiment, the mounting portion 10 is formed to hang downward from the rib 5 like a tongue-shaped piece.
In the present invention, the mounting portion 10 may be formed by increasing the vertical width over the entire length of the rib 5. However, if the tongue-shaped piece is used as in the illustrated embodiment, there is an effect that the amount of FRP used for forming the attachment portion can be reduced.

FIGS. 8 and 9 are perspective views showing other examples of exhaust pipe fixing fittings that can be used in the present invention. A saddle band 11' shown in FIG. 8 has a base end 11a formed inside the saddle band. In addition, the one shown in FIG. 9 has a base end portion 11a formed by twisting the base end side of the saddle band 11'' by 90 degrees.The present invention is directed to such a saddle band 1.
1, 11', and 11'', it is possible to fasten the drain pipe extremely easily and reliably.Of course, the present invention also allows the drain pipe to be fastened using metal fittings such as saddle bands of other shapes. It is clear that it is possible.

[Effects of the invention] As detailed above, according to the waterproof floor pan of the invention, the drain pipe can be correctly fixed at the designed slope. In addition, this fastening work can be performed extremely easily and quickly, and only one type of metal fitting is required for fastening, making it possible to significantly reduce various costs such as material costs and manufacturing costs.
