In this incorporated state, the wall contact portion 23 including the folded wall 25 of the grooved connecting member 22 is fitted to the connecting member fitting portion 41 of the water blocking material 35. Further, the wall contact portion 13 of the connecting member 12 with protrusions is in contact with the band portion 50 of the second end portion 37 of the water blocking material 35.

Next, as shown in FIGS. 5A and 5B, the first wall panel 1 is brought close to the connecting member 3 incorporating the water blocking material 35 from the inside of the bathroom, and the first wall panel 1 is folded back. The portion 7 is inserted into the intermediate portion 38 of the water blocking material 35. Note that FIG. 5A shows a state in which the first wall panel 1 is brought close to the connecting member 3 from the inside of the bathroom, but vice versa, the connecting member 3 is connected to the first wall panel 1 and the first wall panel 1 is placed outside the bathroom. You may approach from.

Then, as shown in FIG. 5B, the folded contact portion 8 of the first wall panel 1 is brought into contact with the first contact portion 51 of the water blocking material 35, and the first wall panel 1 is brought into contact with the first contact portion 51. The folded-back portion 7 of the above is brought into contact with the water-stopping portion 55.

Next, as shown in FIG. 6A, the second wall panel 2 is brought close to the connecting member 3 to which the water blocking material 35 is incorporated and attached to the first wall panel 1 from the inside of the bathroom, and FIG. ), The folded-back portion 7 of the second wall panel 2 is inserted into the intermediate portion 38 of the water blocking material 35. In this state, the folded portions 7 and 7 of the first wall panel 1 and the second wall panel 2 are in a facing state.

After that, although not shown, the protruding connecting member 12 is lowered, and the small diameter portion 17 of the protrusion of the protruding connecting member 12 is moved obliquely downward along the narrow groove 29 of the grooved connecting member 22. Then, the connecting member 12 with protrusions slides from the state shown in FIG. 6 (b) to the state shown in FIG. 7 (a).

As a result, as shown in FIGS. 7 (a) and 7 (b), the first wall panel 1 and the second wall panel 2 are brought into close contact with each other, and the folded-back portions 7 and 7 are brought into close contact with each other, and the first wall panel 1 and the second wall panel 2 are brought into close contact with each other.

Further, the folded portions 7 and 7 of the first wall panel 1 and the second wall panel 2 come into contact with the water blocking portions 55 of the water blocking material 35, respectively. As a result, it is possible to prevent water from passing between the folded-back portion 7 of the first wall panel 1 and the folded-back portion 7 of the second wall panel 2 from the bathroom side, and further improve the watertightness.

(Comparison with comparative example)
By the way, as shown in FIGS. 3 (b) and 7 (c), the water blocking material 35 of the present invention has a central portion 61 substantially parallel to the first and second wall panels 1 and 2 and left and right inclined portions. The bottom portion 54 having 62 is provided, and the distance W1 between the left and right ends of the bottom portion 54 is formed to be substantially the same as or slightly larger than the distance W2 between the first and second contact portions 51 and 52.

As a comparative example different from the configuration of the water blocking material 35 of the present invention, the water stopping material 65 has a problem of water stopping, and while comparing with the problem, the characteristic of the water stopping structure 59 of the present invention. Clarify the composition and effects.

The water blocking material 65 and the water stopping structure 70 of the comparative example have substantially the same configurations as the water stopping material 35 and the water stopping structure 59 of the present invention, except that, as shown in FIG. 8A, the water stopping material is still water. The bottom portion 66 of the material 65 is substantially in the shape of a letter in a plan view, has a small width, and the first contact portion 68 and the second contact portion 69 are formed from the left and right connecting portions 67 of the bottom portion 66. It has a structure that projects laterally in a character shape and has a bulge on the side.

With such a configuration, as shown in FIG. 8 (a), when a force F (see the white arrow) from the outside of the bathroom acts on the bottom 66, or as shown in FIG. 8 (b). When a force F from the left and right sides acts on the left and right abutting portions 68 and 69, the left and right abutting portions 68 and 69 greatly project laterally in a dogleg shape, so an imaginary line (two-point chain line). As shown by, the bottom 66 is easily deformed by moving toward the outside of the bathroom.

On the other hand, the bottom portion 54 of the water blocking material 35 of the present invention is formed from the central portion 61 and the left and right inclined portions 62 in a bow shape in a plan view, and the distance W1 between both ends is shown in FIG. 7 (c). As described above, the distance between the base end portion 57 of the first contact portion 51 and the base end portion 58 of the second contact portion 52 is substantially the same as or slightly larger than the distance W2.

Therefore, even if a force from the inside of the bathroom acts on the bottom 54, or a force from the left and right sides acts on the first and second contact portions 51 and 52, the bottom 54 is a beam (stretched). Since it acts like a beam) and the width of the bottom 54 is large, the first and second contact portions 51 and 52 do not project so much in a dogleg shape to the left and right, so the water blocking material is used. It is hard to be deformed, and the bottom 54 is suppressed from moving toward the outside of the bathroom and being deformed.

By the way, as shown in FIG. 8C, in the water blocking structure 70 incorporating the water blocking material 65 of the comparative example, the force F (pressing force F from the bathroom side against the first and second wall panels 1 and 2 ( When the white arrow (see white arrow) acts, the bottom 66 is pushed to the outside of the bathroom through the folded parts 7 of the first and second wall panels 1 and 2, as shown by the imaginary line (dashed line). Easy to deform outward.

Further, as shown in FIG. 9A, when a force F pulling toward the bathroom side (a force applied from the outside to the inside of the bathroom; see the white arrow) acts on the first and second wall panels 1 and 2, the first and second wall panels 1 and 2. The folded contact portions 8 of the first and second wall panels 1 and 2 move the first and second contact portions 68 and 69 of the water blocking material 65 to the inside of the bathroom as shown by the arrow M.

At that time, the first and second contact portions 68, 69 approach each other by the folded walls 25, 15 of the grooved connecting member and the protruding connecting member 22, 12 as shown by the imaginary line (dashed line). It is crushed in the direction, and the bottom 66 is easily deformed to the outside of the bathroom.

When the bottom portion 66 of the water blocking material 65 is deformed toward the bathroom due to such a cause, a gap is formed between the water blocking portion 71 of the water blocking material 65 and the folded-back portion 7 of the first and second wall panels 1 and 2. It occurs and the water stopping effect is reduced.

On the other hand, in the water blocking structure 59 as shown in FIGS. 7A and 7B incorporating the water blocking material 35 of the present invention, the first and second wall panels 1 and 2 are pushed from the indoor side. Further, even if a force that is pulled toward the room side and further moves laterally and applies a force that is applied to the water blocking material 65 of the comparative example is applied to the water blocking material 35, the water blocking material 35 is stopped as shown in FIG. 7 (c) as described above. The bottom portion 54 of the water material 35 acts like a beam, the water stop material 35 is not easily deformed, and the water stop portion 55 of the bottom 54 suppresses the separation from the first and second wall panels 1 and 2. And the water stopping effect can be maintained.

The water blocking material 35 provided at the connection portion between the first wall panel 1 and the second wall panel 2 does not protrude or be exposed inside the bathroom, and the first wall panel 1 is viewed from the inside of the bathroom. And the connection part of the second wall panel 2 becomes a natural connection, and it looks good.

Further, since the wall panel (first wall panel 1, second wall panel 2) and the connecting member 3 are in contact with each other via the water blocking material 35, the strength of the wall panel connecting structure itself is strong. Also improves.

Although the embodiment for implementing the water-stopping structure of the wall panel according to the present invention has been described above based on the examples, the present invention is not limited to such examples and is described in the scope of claims. It goes without saying that there are various examples within the scope of the technical matters.

Since the water blocking structure of the wall panel according to the present invention has the above-described configuration, it can be applied not only to the connecting portion of the wall panel of the bathroom but also to the connecting portion of the wall panel of the room requiring water stopping in the building. is there.
