Description

[Detailed description of the invention] The present invention relates to a joint structure between a bathtub and a waterproof pan that has excellent waterproofness, durability, and earthquake resistance. An apron having a height that reaches the floor is hung along the outer peripheral wall of the bathtub, and the side ends of the waterproof pan for the bathroom floor are bent to form a rising edge, and the fitting part of the apron is inserted into a predetermined position. Further, a raised edge is inserted between the apron and the bathtub, a joining fitting and a sealing material are interposed between the apron and the waterproof pan, and the apron and the waterproof pan are bolted to the joining fitting. This invention relates to a joint structure between a bathtub and a waterproof pan, characterized in that they are fixed to each other with screws or the like.

Conventional waterproof pans and bathtubs simply have a double structure, and this part is simply bonded with adhesive, so the temperature caused by filling the bathtub with boiling water, etc. If the joint becomes bent due to changes in the bathtub or due to the weight shift between the floor and the bathtub during bathing, or if it is used for a long time or there is an earthquake, this joint can easily separate. As a result, water leaked from this area and corroded the beams of surrounding buildings, especially those on the second floor.

The joining structure according to the present invention relates to a completely new technology developed in view of the drawbacks of the conventional art.

To explain the structure according to the present invention with reference to figures, in Figs. 1 to 3, 1 is a bathtub, and the upper edge 2 facing the washing area has a height that reaches the floor of the washing area. An apron 3 with a lower part bent outward in steps is provided in a hanging manner. Reference numeral 4 denotes a waterproof pan for the bathroom floor, whose side end on the bathtub 1 side is bent upward to form a raised edge 5, and on the horizontal surface adjacent to this raised edge 5 is the apron 3.
A recessed groove 6 is formed into which a fitting portion at the lower end can be inserted. Reference numeral 7 denotes a joining metal fitting interposed between the apron 3 and the waterproof pan 4, the tip of which is formed with a reinforcing part 7' bent into a stepped shape similar to the lower part of the apron 3; Standing piece 8 at the base
is installed protrudingly. 9 and 10 are band-shaped sealing materials made of butyl rubber or the like. 11 is the apron 3
Reinforced plywood that can be reinforced from the back side, 12 is a screw that can fix the joining fitting 7 to the reinforcing plywood 11, 13 is a bolt that can fix the waterproof pan 4 and the joining fitting 7, 1
4 is a nut that can be screwed onto this bolt 13.

In assembling the structure according to the present application, as shown in FIGS. 2 and 3, the rising edge 5 of the waterproof pan 4 is inserted into the back surface of the apron 3, and the reinforcing plywood 11 is attached to the back surface of the apron 3. Next, the joining fittings 7 and the sealing materials 9 and 10 are inserted into predetermined positions between the apron 3 and the waterproof pan 4, respectively, and the apron 3 is
The lower end of the metal fitting 7 is inserted into the groove 6, and the upright piece 8 of the joint metal fitting 7 is fixed to the reinforcing plywood 11 via the screw 12, and this time, the metal fitting 7 is attached to the waterproof pan 4 with the bolt 1.
3 and nuts 14, the entire assembly can be constructed.

The reinforcing plywood 11 in the above embodiment is omitted,
It is also possible to directly fix the joining fitting 7 to the apron 3. In the figure, 15 is the entrance door of the bathroom.

As mentioned above, the structure of the present invention is such that an apron is provided in a predetermined part of the bathtub, and the end of the waterproof pan is raised up, and the raised edge is inserted into the back side of the apron. Water leakage at the joint with the waterproof pan can be completely prevented,
In addition, a joining fitting and a sealing material are interposed between the apron and the waterproof pan, and the apron and the waterproof pan are connected to each other by being fixed to the joining fittings through screws, bolts, etc. So,
The joints are mechanically extremely firmly fixed, completely preventing water leakage, and there is no risk of the joints between the bathtub and waterproof pan coming apart due to weight shifts, temperature changes, earthquakes, etc. It has the characteristics that there is no such thing.
