Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a waterproof pan, and more particularly to an improvement in the structure of a floor pan when forming a unit bath, a toilet unit, a washbasin unit, etc., or a draining portion of a bathtub with a floor pan.

Conventionally, the draining part of the above-mentioned waterproof pan is integrally formed with resin such as FRP in a stepped shape, so after molding, the wall mounting surface part deforms inwardly, outwardly, or upwardly into an arched shape due to contraction of the resin. As a result, variations in dimensional accuracy occur, resulting in disadvantages such as a gap being created between the wall to be mounted and the wall mounting surface.

For this reason, conventionally, to prevent deformation of the draining section, strong reinforcements such as wooden crosspieces and angles were applied to the back of the draining section, but there was a wall-mounting surface made of resin. Deformation and warping are disadvantages that cannot be completely prevented.

The present invention was developed in view of the above-mentioned conventional circumstances, and its purpose is to prevent warping and deformation of the draining section by forming the entire surface of the draining section or the wall mounting surface and the water return surface with metal members. In addition to improving dimensional accuracy, there is no gap between the wall and the wall mounting surface, eliminating the need for deburring and preventing damage even if the drain part comes into contact with obstacles during transportation. It is an object of the present invention to provide a waterproof pan equipped with a drain section.

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

In the figure, A indicates a pan body, and this pan body A is a floor plate of a bath unit, a toilet unit, a washbasin unit, etc., and has a saucer shape, and a drain portion B is integrally formed on its periphery.

The draining section B includes a draining surface section 1 that is vertically disposed from the periphery of the floor surface 1A of the bread body A, a wall mounting surface section 2 that extends outward from the draining surface section 1, and a wall mounting surface section 2 that extends perpendicularly from the mounting surface section 2. The inner wall mounting surface 2 and the water return surface 3 are constructed of a floor surface 1A made of resin such as reinforced plastic and a different material such as stainless steel or other metal. It is integrally formed with a metal member 4.

The metal member 4 has a substantially square shape in longitudinal section, and four embodiments of the metal member 4 are shown in FIGS. 1 to 4.

First, the metal member 4 shown in FIG. 1 has engagement prevention protrusions 5a as engagement parts 5 integrally formed on the back surface of the wall mounting surface portion 2, extending over the entire width of the back surface and extending at appropriate intervals.

The metal member 4 in FIG. 2 has an engaging tooth portion 5b integrally engraved as an engaging portion 5 on the back surface of the wall placement surface portion 2, and a hook for hooking the wall body 6 at the tip of the wall placement surface portion 2. The portion 7a is integrally bent and formed as a means 7 for hooking and fixing the wall body 6.

The metal member 4 in FIG. 3 has a retaining protrusion 5 having a conical tip as an engagement portion 5 on the back surface of the wall mounting surface portion 2.
A wall locking projection 7b is integrally formed as a means 7 for locking and fixing the wall 6 on the upper surface of the wall mounting surface portion 2.

The metal member 4 shown in FIG. 4 has a bent engagement piece 5d formed as an engagement part 5 at the tip of the wall mounting surface 2, and is attached to the water return surface 3 as a hooking and fixing means 7 for the wall 6. A screw hole 7c is drilled.

Then, a metal member 4 is placed around the part corresponding to the drainage part B on the mold 8, and after laying a glass mat 9, a filling resin (FRP,
Other resins) are applied, cured, and then released to form waterproof pans.

At this time, the engagement and removal prevention protrusions 5a, engagement teeth 5b, and removal prevention protrusions 5c shown in FIGS. It bites into a strong bond.

Further, the bending engagement piece 5d shown in FIG. 4 is surface-engaged with the upper end of the water cutting surface 1, and is firmly and irremovably connected as in the above-mentioned embodiment.

The metal member 4 prevents warpage of the drain section B, especially the wall mounting surface section 2, due to shrinkage of the resin after molding.

The wall 6 is erected on the wall mounting surface 2 of the metal member 4 embedded integrally with the bread body A in this manner, and the hook 7a, the wall locking protrusion 7b, and the screw 10 are installed.
to keep it fixed through.

As described above, in the present invention, the draining part or the inner wall mounting surface part and the water returning surface part of the draining part are formed of metal members, so that the wall mounting surface part is prevented from warping or deforming due to shrinkage of the resin after molding. can be prevented.

Therefore, although we have made the most important reinforcements such as wooden beams and angles, the presence of a resin wall mounting surface ensures that the product deforms more reliably than conventional products, which cannot prevent deformation and warping. Warpage can be prevented, the cost is low, and the dimensional accuracy of the waterproof pan itself can be improved.

There is no gap caused by warping or deformation between the wall that is fixed on the upper wall mounting surface and the wall mounting surface, which is effective in terms of interior aesthetics and sealing performance. It's large.

Furthermore, even if the drainage part collides with an obstacle during transportation, it will not be damaged because it is made of metal, and there is no need for deburring, which is a characteristic of resin waterproof pans.

Thus, the intended purpose can be achieved.
