Description

[Detailed Description of the Invention] The present invention relates to a water-stop structure for a bathtub unit installed in a bathroom.

The water-stopping structure of a conventional bathtub unit is shown in a cross-sectional view in FIG.

In the figure, reference numeral 1 denotes a bathtub unit, which is usually integrally molded of metal such as stainless steel or plastic, and a back-up material is provided in the gap between the outer peripheral surface of the folded edge 2 of the bathtub unit 1 and the surrounding wall surface 3 of the bathtub. By interposing 4 and filling caulking material 5 such as putty from above,
This prevents water from leaking to the building foundation floor 6 on which the bathtub unit 1 is placed.

Note that 7 is a base interposed between the bathtub unit 1 and the floor surface 6.

Bathtubs having a conventional water-stop structure using caulking material 5 such as putty as described above have various problems.

In other words, both hardening and non-hardening types of caulking material 5 are used, but when the former is used, the caulking material does not have elasticity, so repeated use may cause slight damage to the edges of the bathtub unit 1. However, if dimensional changes such as warping occur, cracks will form in the caulking material 5, causing water leakage to the building foundation floor 6.

Furthermore, when a non-curing caulking material is used, children often pry out the caulking material 5 with their fingers, causing water leakage.

Such water leakage causes accelerated deterioration of the building foundation floor 6.

Furthermore, it is difficult to finish the surface of the caulking material 5 into a uniform surface with no unevenness, which causes problems in the conventional structure, such as the caulking portion spoiling the aesthetics of the bathroom and requiring a great deal of effort to wipe off the caulking material adhering to the wall surface. was there.

The object of the present invention is to provide a new water-stopping structure for a bathtub unit that solves the above-mentioned conventional problems.

The present invention will be described in detail below with reference to the drawings.

FIG. 2 is a cross-sectional view of one embodiment of the present invention, and the same reference numerals as in FIG. 1 are used for parts that are the same as those of the prior art.

That is, 1 is a bathtub unit, 6 is a building foundation floor surface on which this unit 1 is installed via a base 7, and 3
is the surrounding wall surface that partitions the bathtub.

To explain the present invention according to the construction order, first, the frame 8 is positioned on the wall surface 3 around the bathtub at a height slightly lower than the planned upper edge position of the bathtub unit 1.
Fixed at 0 etc.

This frame body 8 includes fins 8A for attachment to the wall surface 3, horizontal fence plates 8B integrally connected to the ends of the fins 8A, and upright fins integrally connected to the ends of the fence plates 8B. 8C
Furthermore, the upright fins 8C are formed in a closed curve shape with a contour that is approximately the same as the contour shape of the folded line groove 2A of the bathtub unit 1.

Here, as the watertight material 9, a rubber plate, various sealants, etc. can be used, but commercially available butyl rubber tape is suitable from the viewpoint of workability.

Next, along the inside of the folded line groove 2A of the bathtub unit 1,
The bathtub unit 1 is filled with a filler 11 such as urethane foam, which cures at room temperature and is extremely soft when discharged from the storage container, and the upright fins 8C of the frame 8 are fitted into the folded line grooves 2A. is installed on the base 7.

Next, the surrounding wall surface 3 of the bathtub and the folded edge 2 of the bathtub unit 1
A gasket 13 made of a rubber-like elastic material such as soft vinyl chloride and formed into a frame shape to match the outline of the gap 12 is fitted into the gap 12 formed between the gap 12 and the outer circumferential surface to perform waterproof construction. is completed.

The gasket 13 can also be used as a type in which it is simply embedded while being elastically deformed, but as shown in the second figure, a groove is provided on the outer surface of the gasket body, and tongue pieces 13A and 13B located on both sides of the groove are provided. The thickness of the base of the tongue pieces 13A, 13B is made slightly thinner so that the tongue pieces 13A, 13B can be easily bent.After fitting the gasket body into the gap, the string-like zipper member 13C can be pushed into the groove.
If B can be press-fitted to the wall 3 and the side of the bathtub unit 1, then the gasket 13 can be attached to the zipper.
If you use type gasket, workability will be further improved.

As explained above in the embodiments, the present invention has a bathtub unit 1.
A positioning frame body 8 having an upright fin 8C formed to have an outline approximately equal to the shape outline of the folding line groove 2A is fixed to the surrounding wall surface 3 of the location where the bathtub unit 1 is installed via a watertight material 9 such as butyl rubber. The bathtub unit 1 is installed with the upright fins 8C of the body 8 fitted into the folded line grooves 2A of the bathtub unit 1, and a rubber-like elastic material is installed in the gap 12 between the outer peripheral surface of the folded edge 2 of the bathtub unit 1 and the surrounding wall surface 3. This is a water-stop structure for a bathtub unit in which a gasket 13 made of material is fitted, and has the following advantages.

(a) The gap between the wall around the bathtub and the bathtub unit is designed to stop water with a pre-formed gasket without using caulking, so even if the bathtub unit warps or otherwise slightly deforms due to repeated use. Due to the elasticity of the gasket, changes in the gap can be sufficiently absorbed.

(b) Since the bathtub has a triple water-stopping structure consisting of the gasket 13, the frame body 8, and the watertight material 9, leakage of water to the foundation floor of the building below the bathtub is almost completely prevented.

(c) By using the frame 8, the bathtub unit 1 can be positioned reliably and quickly.

(d) Unlike conventional methods, there is no need to perform any incidental work associated with waterproofing construction, such as removing unevenness from the caulking agent surface or wiping off the caulking agent that has adhered to the surrounding area, so the overall work can be done quickly and can give a clean appearance.
