Description

The present invention relates to a wall panel connecting structure for connecting wall panels to each other, and particularly to a wall panel connecting structure for connecting wall panels to which water leakage prevention means is applied, such as in a bathroom.

Conventionally, as a connecting material for connecting two wall panels to each other, one of the two wall panels and the connecting material is provided with a protrusion consisting of a neck and a large-diameter tip head, and the other is provided with a vertically elongated hole and a large hole. A configuration is known in which an engaging hole is provided and the protrusion is engaged with the engaging hole (see Patent Documents 1 and 2).

Further, the following structure is known as a mounting structure of a column panel (door top panel) mounted on a door in a bathroom. Reinforcing materials are attached to the connecting parts of the column panel and the wall panel, respectively, and the connecting members having the first engaging part and the second engaging part that can be positioned vertically with respect to both reinforcing materials are engaged with both reinforcing materials. There is known a structure in which a column panel is attached to a wall panel by allowing the column panel to be attached (see Patent Document 2).

It is known that a wall panel that is perpendicular to or in line with the door is provided with a door lateral corner angle or a door lateral flat angle that is shorter than the height of the wall panel by the height of the upper panel of the door so as to be in contact with the floor surface (patented). Reference 4).

Connecting portions with engaging holes are provided at both ends of the back surface of the door upper wall panel, and engaging protrusions with a huge tip are projected from the panel receiving portion protruding from the bathroom wall panel. It is known that the door upper wall panel is attached to the bathroom wall panel by engaging the engaging protrusion with the engaging hole (see Patent Document 5).

By the way, FIG. 7 shows a conventional waterproof structure around the floor of the wall panel 50 of the bathroom. In this waterproof structure, as shown in FIGS. 7A and 7B, a waterproof molding 52 is inserted into the gap 51 between the connecting portions of the two wall panels 50 for waterproofing, and further, on the floor 55. The caulking 57 is filled on the front side (see FIG. 7C) of the back guard 56 when viewed from the bathroom.

Japanese Patent No. 2627394 Japanese Patent No. 5092441 Japanese Unexamined Patent Publication No. 2004-011221 JP-A-2009-114692 Japanese Unexamined Patent Publication No. 2009-263939

In the conventional waterproof structure around the floor of the wall panel 50 of the bathroom shown in FIG. 7, the water that has entered the gap of the fin 53 of the waterproof molding 52 flows downward, is dammed by the caulking 57, and further downward. The structure is such that water leakage is prevented without invading the back guard 57 side.

Since a back guard 56 is provided around the floor of the wall panel 50 in the bathroom, when the caulking 57 is filled, the caulking 57 is confined in the floor 55, the back guard 56, and both side ends of the wall panel 50. It does not flow out.

However, for example, at the connecting portion between the wall panel 50 and the door upper panel, since the floor 55 and the back guard 56 are not provided, when the caulking 57 is filled, the caulking 57 flows downward and is difficult to fill. ..

An object of the present invention is to solve the above-mentioned conventional problems, and even if there is no floor or back guard below or behind the gap between two panels to be connected, caulking can be performed during caulking filling. The challenge is to realize a wall panel connection structure that can stop the flow.

In order to solve the above problems, the present invention is a connection in which two wall panels arranged with a gap are fitted to the back surface of the wall panels over the two wall panels and the wall panels are connected to each other.

The neck portion 30 of the protruding portion is formed to be smaller than the width of the narrow width portion 19 of the slit 17.

(Action)
The operation of the wall panel connecting structure having the above configuration when used for connecting the door upper panel 3 and the wall panel 6 will be described below.

As shown in FIGS. 2A and 2B, when the door upper panel 3 and the wall panel 6 adjacent to each other are connected by the connecting member 1, the large diameter portions 31 of the left and right protrusions 29 of the connecting member 1 are connected. , The wide portion 18 of the slit 17 of the vertical rail 12 is inserted into the slit 17, and the connecting member 1 is moved downward to fit the large diameter portion 31 of the protrusion 29 into the narrow portion 19. The folded-back portion 25 is inserted into the gap between the reinforcing member 10 and the vertical rail 12.

Then, in the door upper panel 3 and the wall panel 6, the vertical rail 12 abuts on the left and right abutting portions 23 of the connecting member 1, and the left and right protrusions of the connecting member 1 on the narrow portion 19 of the slit 17 of the vertical rail 12. By fitting the portions 29 so that they do not come off, as shown in FIGS. 3A and 3B, the portions 29 are fixed to the connecting member 1 and connected to each other via the connecting member 1.

FIG. 1B is a view in which a part of the wall panel 6 (the portion indicated by the alternate long and short dash line) is broken for the convenience of explanation in a state where the door upper panel 3 and the wall panel 6 are connected by the connecting member 1. However, as shown in this figure, the tongue portion 26 formed at the lower end of the connecting member 1 is configured to extend toward the surface side below the gap between the door upper panel 3 and the wall panel 6.

After connecting the door upper panel 3 and the wall panel 6 with the connecting material 1, the caulking 35 extends from the gap between the door upper panel 3 and the wall panel 6 into the recess 24 at the lower part of the connecting material 1 and above the tongue portion 26. (See FIG. 3 (b)). Further, as shown in FIGS. 3A and 3B, the waterproof molding 34 is inserted into the gap between the door upper panel 3 and the wall panel 6.

The caulking 35 filled from the gap between the door upper panel 3 and the wall panel 6 into the recess 24 hardens over time, but immediately after filling, it is fluid and therefore flows downward. However, by catching it from below at the tongue portion 26, the caulking 35 is prevented from flowing downward.

The caulking 35 is present on both sides of the lower part of the water blocking molding 34 from the gap between the door upper panel 3 and the wall panel 6 into the recess 24. As a result, as in the case of the conventional example shown in FIG. 7B, the water that has entered the gap between the door upper panel 3 and the wall panel 6 and has entered the fin 36 of the water blocking molding 34 can flow down. It is dammed by the caulking 35 and produces a water blocking effect. As a result, the risk of water leaking to the outside through the gap between the door upper panel 3 and the wall panel 6 can be reduced.

The connecting member 1 of the first embodiment is applied to the connecting structure of the door upper panel 3 and the wall panel 6 as described above, but is not limited to such a connecting structure. That is, of the two wall panels 6 adjacent to each other, the lower end of one of the wall panels 6 is located above the floor surface, does not come into contact with the floor surface, and is as shown in FIG. 7 (c). Even in the case of a configuration without a back guard, by providing the tongue portion 26 at the lower end of the recess 24 of the connecting member 1, the caulking 35 can be held without flowing downward.

For example, in a unit bath, one of the two wall panels 6 adjacent to each other has no bathtub pan below the wall panel 6 and is used as an installation part of an attachment device, and the lower end of the one wall panel 6 is used. Is located above the floor surface and does not have a back guard. By providing the tongue portion 26 at the lower end of the recess 24 of the connecting member 1 of the two wall panels 6, the caulking 35 can flow downward. It becomes possible to hold without.

(Example 2)
Example 2 of the wall panel connecting structure according to the present invention will be described with reference to FIGS. 5 and 6. The connecting member 41 of the second embodiment is a member for connecting wall panels orthogonal to each other, and here, a configuration in which the door upper panel 3 and the wall panel 6 in the bathroom are connected orthogonally to each other (see FIG. 1A). Will be described.

The door upper panel 3 and the wall panel 6 connected by the connecting member 41 of the second embodiment are arranged orthogonal to each other as shown in FIGS. 1 (a), 6 (a), and 6 (b). The configuration of the door upper panel 3 and the wall panel 6 itself is the same as the configuration in the first embodiment, respectively.

As shown in FIGS. 5A and 5B, the connecting member 41 of the second embodiment has a configuration in which the left and right contact portions 42 are orthogonal to each other as compared with the connecting member 1 of the first embodiment. Although they are different, they are the same for other configurations, so the same code is used for the same configuration.

In particular, also in the connecting member 41 of the second embodiment, similarly to the connecting member 1 of the first embodiment, the tongue portion 26 extending horizontally from the lower end of the concave portion 24 to the surface side is formed so as to be bent.

In the connecting structure of the door upper panel 3 and the wall panel 6 connected by the connecting member 41 of the second embodiment, as shown in FIG. 6B, the door upper panel 3 and the wall panel 6 are connected at right angles to each other. Except for the configuration, the door upper panel 3 and the wall panel 6 using the connecting member 1 of the first embodiment are substantially the same as the connecting structure for connecting to each other.

Also in the connecting structure to which the connecting member 41 of the second embodiment is applied, as in the first embodiment, the gap between the door upper panel 3 and the wall panel 6 and above the tongue portion 26 of the recess 24 are shown in FIG. 6 (b). As described above, the caulking 35 is filled, and the water blocking molding 34 is further inserted into the gap between the door upper panel 3 and the wall panel 6 from the surface side.

Immediately after the caulking 35 is filled, even if it flows downward, it is received by the tongue portion 26 and does not flow downward. Therefore, also in the second embodiment, the water is stopped by the caulking 35 and the water stop molding 34 in the gap between the door upper panel 3 and the wall panel 6 and above the tongue portion 26 of the recess 24.

Although the embodiment for implementing the wall panel connecting structure 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 connecting structure of the wall panel according to the present invention has the above-described configuration, at least one wall panel is used in connecting the door upper panel and the wall panel in the bathroom, connecting adjacent wall panels in other building structures, and the like. Even when the lower end of the door is above the floor surface and there is no back guard, it is useful for the panel connection structure for each application where water stoppage is required.
