(In the first embodiment, it is simply referred to as “wall panel 6”).

  In the first embodiment, as described above, the connecting member 1 of the bathroom door upper panel 3 and the wall panel 6 will be described. In the description of the first embodiment, the outer side is referred to as the rear side when viewed from the bathroom, and the inner side is referred to. Say the front side.

  As shown in FIG. 1A, the door 2 is provided so as to be openable and closable within the door frame 7, and the door upper panel 3 having a smaller vertical dimension than the wall panel 6 is placed on the door frame 7. Has been. In the first embodiment, one side of the door upper panel 3 is linearly connected to the wall panel 6 by the connecting member 1 for the flat portion, and the other is connected to the other wall panel 6 in the second embodiment described later. It is connected at right angles to the connecting member 41 for the corner.

  FIGS. 2A and 2B show a state in which the door upper panel 3 and the wall panel 6 are linearly arranged. Although the wall panel 6 and the door upper panel 3 have different vertical dimensions, their structures are as follows. Since they have substantially the same configuration, the configuration will be described here with the door upper panel 3 as the center.

  As shown in FIGS. 2A and 2B, the door upper panel 3 includes a reinforcing member 10 that serves as a core, a surface material 11, and a vertical rail 12 provided on the back side of the left and right ends of the surface material 11. And. For example, a material such as gypsum board is used for the reinforcing material 10, and the surface side thereof is covered with the surface material 11.

  The surface material 11 is made of a metal thin plate, and a thin film such as vinyl chloride is applied to the surface of the surface material 11 so as to have rust prevention, water resistance, and corrosion resistance. As shown in FIGS. 2A and 2B, the surface material 11 is bent at the side end so that the cross section along the vertical rail 12 is formed in a substantially U shape on the back side. 13 is formed.

  The vertical beam 12 is formed in a substantially square pipe shape in cross section, and a slit 17 for fitting a connecting material is formed in the back wall 15. The slit 17 includes a wide portion 18 and a narrow portion 19. The vertical beam 12 is held between the bent portions 13 of the surface material 11, and a dowel (not shown) provided on the back surface is engaged with a dowel hole (not shown) formed in the surface material 11. It is fixed by the part 20.

  The adjacent wall panel 6 and door upper panel 3 having the above-described configuration are linearly arranged in the same vertical plane as shown in FIGS. 2 (a) and 2 (b). As shown in (b), they are connected via the connecting material 1.

  The connecting material 1 is formed by bending a metal material into a shape as shown in FIGS. That is, the connecting member 1 includes left and right contact portions 23, a recess 24 between the left and right contact portions 23, left and right folded portions 25, and a tongue portion 26 formed at the lower end of the recess 24. ing.

  The recess 24 is formed on the rear side from the left and right contact portions 23 (in the opposite direction to the wall panel. In the structure in which the door upper panel 3 and the wall panel 6 are connected, the door upper panel 3 and the wall panel 6 correspond to the opposite directions. It is a configuration that is recessed toward

  The left and right folded portions 25 are provided on the outer side in the lateral width direction with respect to each of the left and right contact portions 23 (in the wall panel direction. In the structure in which the door upper panel 3 and the wall panel 6 are connected, (Corresponding to the direction of the wall panel 6).

  When the wall panel 6 and the door upper panel 3 are connected to each other in the connecting member 1, the tongue portion 26 is connected to the wall panel 6 and the door upper panel 3 at the lower end located between the wall panel 6 and the door upper panel 3. It is substantially vertical and is formed so as to extend toward the surface side (in the direction of the wall panel. In the structure in which the door upper panel 3 and the wall panel 6 are connected, it corresponds to the direction of the door upper panel 3 and the wall panel 6). .

  In the first embodiment, the tongue 26 is bent substantially horizontally from the lower end of the recess 24 toward the surface side (corresponding to the direction of the wall panel 6 in the structure in which the wall panel 6 and the door upper panel 3 are connected). It is formed to extend. As shown in FIGS. 4A and 4B, the tongue portion 26 is formed so as to be substantially the same as the position on the surface side of the contact portion 23.

  As shown in FIGS. 4A and 4B, the left and right contact portions 23 are each provided with a protruding portion 29 projecting to the surface side. The protruding portion 29 is formed of a neck portion 30 fixed to the contact portion 23 and a large-diameter portion 31 that expands in a tapered shape toward the front via the neck portion 30.

  The maximum diameter of the large-diameter portion 31 of the protrusion 29 is smaller than the width of the wide width portion 18 of the slit 17 and larger than the width of the narrow width portion 19. The neck portion 30 of the protruding portion is formed smaller than the width of the narrow width portion 19 of the slit 17.

(Function)
The operation when the connecting member 1 having the above configuration is 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 connecting the door upper panel 3 and the wall panel 6 adjacent to each other with the connecting material 1, the large-diameter portions 31 of the left and right protrusions 29 of the connecting material 1 are used. Then, it is inserted into the slit 17 from the wide width portion 18 of the slit 17 of the vertical rail 12, the connecting material 1 is moved downward, and the large diameter portion 31 of the projection portion 29 is fitted to the narrow width portion 19. The folded 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 beam 12 comes into contact with the left and right contact parts 23 of the connecting material 1, and the left and right protrusions of the connecting material 1 are formed in the narrow width part 19 of the slit 17 of the vertical beam 12. By fitting so that the part 29 does not come out, as shown in FIGS. 3A and 3B, the parts 29 are fixed to the connecting material 1 and connected to each other via the connecting material 1.

  FIG. 1B is a diagram in which a part of the wall panel 6 (part indicated by a two-dot chain line) is broken for convenience of explanation in a state in which the door upper panel 3 and the wall panel 6 are connected by the connecting material 1. However, as shown in this figure, the tongue 26 formed at the lower end of the connecting member 1 is configured to extend to 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 below the connecting material 1 and above the tongue 26. (See FIG. 3B). Further, as shown in FIGS. 3A and 3B, the water stop 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 as time elapses, but immediately after filling, the caulking 35 flows downward. However, when the tongue 26 is received from below, the caulking 35 is prevented from flowing downward.

  The caulking 35 exists on both sides of the lower part of the water stop molding 34 from the gap between the door upper panel 3 and the wall panel 6 into the recess 24. Thus, as in the case of the conventional example shown in FIG. 7B, even if the water that has entered the gap 36 between the door upper panel 3 and the wall panel 6 and enters the fin 36 of the water stop molding 34 flows down, It is dammed by the caulking 35 and a water stop effect is produced. As a result, the risk of water in the bathroom leaking outward from the gap between the door upper panel 3 and the wall panel 6 can be reduced.

  In addition, although the connection material 1 of Example 1 was applied to the connection structure of the door upper panel 3 and the wall panel 6 as mentioned above, it is not restricted to such a connection structure. That is, of the two wall panels 6 adjacent to each other, the lower end of one wall panel 6 is located above the floor surface, does not touch the floor surface, and as shown in FIG. Even in the case of a configuration without a back guard, it is possible to hold the coking 35 without flowing downward by providing the tongue 26 at the lower end of the recess 24 of the connecting member 1.

  For example, in the unit bath, one of the two wall panels 6 adjacent to each other, one wall panel 6 is used as an installation part of the attachment device without a bathtub pan below it, and the lower end of one wall panel 6 Is located above the floor surface and has no back guard, the tongue 26 is provided at the lower end of the recess 24 of the connecting member 1 of the two wall panels 6 so that the caulking 35 flows downward. It becomes possible to hold it.

(Example 2)
Embodiment 2 of the connecting material according to the present invention will be described with reference to FIGS. The connecting member 41 of the second embodiment is a member that connects wall panels that are orthogonal to each other. Here, the door upper panel 3 and the wall panel 6 in the bathroom are connected to each other orthogonally (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 FIG. 1 (a), FIG. 6 (a), and (b). The configurations of the door upper panel 3 and the wall panel 6 themselves are the same as those in the first embodiment.

  Compared with the connecting material 1 of the first embodiment, the connecting material 41 of the second embodiment is configured such that the left and right contact portions 42 are orthogonal to each other, as shown in FIGS. Although it is different, since it is the same for other configurations, the same reference numerals are used for the same configurations.

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

  As shown in FIG. 6B, the door upper panel 3 and the wall panel 6 are connected to each other at right angles to each other, as shown in FIG. 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 in which they are connected to each other.

  Also in the connection structure to which the connection 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 the tongue 26 of the recess 24 are shown in FIG. As described above, the caulking 35 is filled, and the water stop molding 34 is inserted into the gap between the door upper panel 3 and the wall panel 6 from the surface side.

  Even if the caulking 35 flows downward immediately after being filled, it is received by the tongue 26 and does not flow downward. Therefore, also in Example 2, water is stopped by the caulking 35 and the water stop molding 34 above the gap between the door upper panel 3 and the wall panel 6 and the tongue portion 26 of the recess 24.

  As mentioned above, although the form for implementing the connection material which concerns on this invention was demonstrated based on the Example, this invention is not limited to such an Example, The technical scope described in the claim It goes without saying that there are various embodiments within the scope of the matter.

  Since the connecting material according to the present invention is configured as described above, the lower end of at least one of the wall panels is used for connecting the door upper panel and the wall panel in a bathroom, or connecting adjacent wall panels in other building structures. Even when there is no back guard above the floor surface, it is useful for the connection structure of panels for various applications that require water-stopping.
