  Embodiments of the present invention will be described below with reference to the accompanying drawings. In addition, the 1st wall surface panel demonstrated below has a base material formed with non-metallic materials, such as a cement board, and a 2nd wall surface panel is a base material formed with the metal plate. .

FIG. 2 is a plan view of an example of a unit bathroom. In this example, one of the four wall surfaces is formed by the first wall surface panel W1, and the other three surfaces are formed by the second wall surface panel W2. That is, in the figure, at the corners A and B, it is necessary to interconnect the first and second wall surface panels W1 and W2.
Here, a representative example of the first wall panel W1 is a base coat layer and a top coat layer formed on the surface of a special cement plate or the like, and a back coat layer formed on the back surface. From the back of the layer, a structure in which a hollow back frame made of aluminum or the like is attached by welding or bonding is used for reinforcement and connection, but is not limited thereto.
In addition, the second wall surface panel W2 is formed by using a metal plate such as an aluminum zinc steel plate as a base material, forming a base layer, a surface layer such as PET resin on the surface, and forming a back layer on the back surface. Although the thing which comprises the structure which bent | folded and formed the connection rib is employ | adopted, it is not limited to it.

The first wall surface panel W1 and the second wall surface panel W2 have the structural differences as described above, but due to their structural features, the second wall surface panel W2 is more than the first wall surface panel W1. Generally, it is formed to be thin.
That is, both panels W1 and W2 have a large difference in the panel side end portions to be connected, and require connecting members having shapes suitable for the respective side end portions. Furthermore, there is a difference in weight and strength, and it is necessary to connect them in consideration of these points.
Below, this corner part connection structure, the corner connection member of a wall surface panel, and the corner connection reinforcement of this invention are demonstrated. In addition, since the corners C and D are connected by the same type of conventional connection method, the description is omitted.

FIGS. 3A and 3B are diagrams showing a procedure for fixing the corner connecting member, where FIG. 3A is a view before connection, and FIG. 3B is a view showing the state after connection from the back side of the panel. FIG. 4 is a partial perspective view of the corner connecting member 10.
The first wall panel W1 includes a panel main body 1a having a base material as a cement board, and a hollow back frame 1b that is mounted on the back surface of the panel main body 1a and that runs vertically and horizontally (only the upper and lower sides are shown in the figure). Is done. On the panel side end face side of the back frame 1b, there is formed a saddle hole 1c in which large and small holes having different hole diameters are communicated vertically. In addition, the code | symbol 1d is a cutting step part.
On the other hand, the second wall surface panel W2 is integrally formed with a panel main body 2a whose base material is made of metal, and a hook-shaped connecting rib 2b is formed at the end. The connecting rib 2b is formed by bending the end of the panel body 2a.

The corner connecting member 10 includes a connecting piece 11 fixed along the side edge of the back frame 1b, and a connecting piece fixed to the connecting rib 2b and bent at a substantially right angle and extended. The surrounding wall 12 has a structure formed in the longitudinal direction, and has a lamellar cross-sectional shape when viewed from above as shown in the figure. The corner connecting member 10 is preferably manufactured by processing a metal plate, but other materials having the same strength as metal may be used.
Such a connecting member 10 has an inner assembled metal fitting 30 provided with a plurality of long holes (not shown) in the vertical direction at predetermined intervals in a hollow back frame 1b attached to the side end of the first wall panel W1. Insert the back frame mounting piece 11 formed with the sill hole 13 corresponding to the long hole to the side surface of the hollow back frame 1b and screw the fixing screw S1 from the slat hole 13 toward the long hole of the inner assembly 30. The inner assembled metal fitting 30 is driven into the back frame 1b and buried.
Thus, after attaching the connecting piece 11 to the back frame 1b of the first wall surface panel W1, the connecting rib 12b surrounds the connecting rib 2b formed at the side end of the second wall surface panel W2. In this state, the screw S2 is screwed into the connecting rib 2b from the screw hole 14 on the surrounding wall side to fix the second wall surface panel (see FIGS. 3A and 3B).

  Thus, by using the corner connecting member 10 integrally including the connecting piece 11 for the first wall surface panel W1 and the connecting wall 12 for the second wall surface panel as a connecting member, different shapes and different base materials are obtained. The side ends of the first and second wall surface panels W1, W2 can be connected to each other.

  The corner connecting member 10, together with the inner assembled metal fitting 30, is slightly lower in height than the wall panel W 1, W 2, and is matched to the height of the cut step 1 d provided at the upper end on the back frame 1 b side. This is because the height positions of the upper surfaces of the wall surface panels W1 and W2 and the upper surface of the horizontal connection piece portion 21 of the corner connection reinforcing tool 20 when a corner connection reinforcing tool 20 (see FIG. 1) described later is inserted. This is to keep it constant.

  Next, with reference to FIGS. 1 and 5, a corner connection reinforcing tool 20 for reinforcing the corner connection will be described. FIG. 1 is a perspective view for explaining a procedure of inserting the corner connecting reinforcing tool 20 of the present invention into the wall surface panels W1 and W2 after being connected by the corner connecting member 10. FIG. ), (B) are plan views showing the insertion procedure of the corner connecting reinforcing tool 20. The corner connecting reinforcing tool 20 is integrally formed by punching and bending a metal plate. The corner connecting reinforcement 20 may be made of a material other than metal.

  The first and second wall surface panels W1, W2 are connected by a corner connecting member 10 and can be connected and reinforced by inserting a corner connecting reinforcing tool 20 from above. The corner connection reinforcing tool 20 is formed with first and second leg pieces 22 and 23 in the horizontal connection piece portion 21, and the first leg piece 22 is formed in the hollow portion of the hollow back frame 1 b of the first wall panel W 1. In addition, the upper ends of the first and second wall panels W1 and W2 are fixedly connected by press-fitting the second leg pieces 23 into the connection surrounding wall 12 of the corner connecting member 10 from above. . Further, a positioning fold piece 24 is formed at one end of the first leg piece 22 at substantially right angles so as to be in surface contact with the inner surface of the back frame 1b. Note that the positioning folding piece 24 may not be formed.

  More specifically, as shown in FIGS. 5A and 5B, the first leg piece 22 is press-fitted between the inner assembly 30 and the back frame 1b. The second leg piece 23 is inserted so as to be in surface contact with a surface orthogonal to the side end surface in the back frame 1b, while the second leg piece 23 is in contact with the back surface of the panel body 2a inside the connection surrounding wall 12 of the corner connection member 10. Press insert. The portion indicated by the thick line in FIG. 5B shows the leg pieces 22 and 23 and the positioning folding piece 24 that are press-fitted.

  As shown in FIG. 5, the widths of the first and second leg pieces 22, 23 are formed to match the sizes of the back frame 1 b and the connecting surrounding wall 12. Further, the length (width) (L1, L2 in the figure) of the horizontal connecting piece portion 21 up to the bent position of each leg piece is the side edge position of the back frame 1b, the second wall panel body 2a. The length is determined by the position of the back surface, and in the case of the present embodiment, the length (L1) to the first leg piece 22 is slightly longer. Moreover, although the width | variety of the center part of the horizontal connection piece part 21 which does not bend the leg piece is shorter than L2, it is not limited to this, You may make it wider in order to raise reinforcement power . The length and shape of the first and second leg pieces 22 and 23 will be described later.

  Thus, since it can fix with the two leg pieces 22 and 23 from the upper part of both the panels connected with the corner connection member 10, the connection in a corner part can be hold | maintained with high connection intensity | strength. . Furthermore, it is possible to connect and reinforce the corner connection upper end portion, which tends to be weak, and to prevent the upper end from opening.

In addition, the corner connecting reinforcing tool 20 is provided with the following various devices in order to facilitate the press-fitting of the first and second leg pieces 22 and 23 into the wall surface panels W1 and W2.
FIG. 6 is a front view showing the characteristics of each part of the corner connecting reinforcing tool 20.
First, the first leg piece 22 is longer downward than the second leg piece 23. Thereby, after inserting the 1st leg piece 22 in the predetermined position on the 1st wall surface panel side, the 2nd leg piece 23 can be inserted in the predetermined position on the 2nd wall surface panel side. That is, by providing a step on the leg piece, it is not necessary to insert two leg pieces at the same time with respect to both wall surface panels W1 and W2, and it is possible to insert them one by one, thereby facilitating the construction.
Further, a positioning fold piece 24 is formed at one end of the first leg piece 22 (see FIG. 4). According to this, by inserting the first leg piece 22 into a predetermined position on the first wall surface panel side, it is possible to determine the mounting angle of the corner connection reinforcing tool 20 with respect to the first wall surface panel W1, and to determine the second leg. By inserting the piece 23 into a predetermined position on the second wall surface panel side, the angle of the second wall surface panel W2 with respect to the first wall surface panel W1 can be positioned at a predetermined angle.
Furthermore, since the tapered leading portion 22a is formed at the lower portion of the first leg piece 22, the insertion into the hollow portion of the back frame 1b is facilitated. Similarly, since the tapered leading portion 23a is also formed in the lower portion of the second leg piece 23, it is easy to insert it into the connection surrounding wall 12.
