2. Description of the Related Art FIG. 9 is a perspective view showing a room space A such as a bathroom with a part cut away. In the chamber space A, wall panels 1, 1, ... Are erected on the upper surface 7b of the rising edge portion 7a provided on the outer peripheral portion of the waterproof pan 7, and
It is formed by supporting the ceiling panel 2 by the upper end surface of each wall panel 1,1 .... FIG. 10 is an exploded perspective view showing a connecting portion between the waterproof pan 7 and the wall panel 1. In the wall panel 1, a base plate 4 such as an asbestos slate plate is screwed to a holding frame 3 framed by a shaped steel such as a C-shaped steel or a square pipe, and a surface building material 5, 5 such as a tile is attached to the surface of the base plate 4. ，
These are aligned and glued. In the holding frame 3 of the wall panel 1, the lower end surface 3a is provided at both ends thereof with a downward opening 3c formed by a shaped steel used in the vertical direction. To connect the wall panel 1 to the waterproof pan 7, the hook metal fitting 8 is used. The hook fitting 8 is formed by bending a seat plate portion 8a and a hook portion 8b into a substantially L shape, and has two boss portions 9 and 9 that bulge upward in the seat plate portion 8a. Are formed. Further, in the hook metal fitting 8, when the hook portion 8b is hooked on the rib 7c attached to the rising edge portion 7a of the waterproof pan 7, the seat plate portion 8a comes into contact with the upper surface 7b of the rising edge portion 7a. It is like this. Therefore, one boss portion 9 of the seat plate portion 8a
To the other boss 9 in the hook metal fitting 8 (seat plate portion 8a), the opening 3c provided on the lower end surface 3a of the wall panel 1 is fitted to the wall panel adjacent to the other boss 9. The lower end surface opening (3c) (not shown) is fitted.

On the other hand, FIG. 11 is a partially cutaway perspective view showing a disassembled portion of the wall panel 1 and the ceiling panel 2.
The ceiling panel 2 is formed by laminating a backing material 10 such as a gypsum board on a steel plate 6 having a folded edge 2a on the outer periphery thereof. To connect the ceiling panel 2 to the wall panel 1, a clip metal fitting 11 is used that is complicatedly bent so as to have a substantially F-shape as a whole (illustrated in an inverted state in the figure). When mounting the clip metal fitting 11, the vertical split portion 11a is provided at the folding edge 2a of the ceiling panel 2.
After inserting into the wall panel 1
The holding frame 3 is pushed in so that the top side 3b of the holding frame 3 is clamped.

[0004]

When the wall panel 1 and the waterproof pan 7 are connected (see FIG. 10), the hook metal fitting 8 used for the connection can be applied only to the connection point between the adjacent wall panels 1. It is a thing. That is, only two places are joined to one wall panel 1,
Inevitably, the standing state remains instable, which is a cause that the wall panel 1 cannot be upsized.

On the other hand, when connecting the wall panel 1 and the ceiling panel 2 (see FIG. 11), the work is performed from the inspection port (see arrow B in FIG. 9) provided in the ceiling panel 2 to the space above the ceiling. It is something that I have no choice but to lean on. Moreover, since the clip metal fitting 11 must be positioned on the opposite side (back surface side) of the wall panel 1 when viewed from the operator side, the operator is forced to take a very unreasonable posture, which makes the work difficult. Was extremely high. Not only that, the mounting state of the clip metal fitting 11 on the wall panel 1 cannot be visually confirmed, and thus the reliability is extremely low.

The present invention has been made in view of the above circumstances, and the horizontal plate member forming the floor portion or the ceiling portion can be securely connected to the wall panel, and the connecting work is very easy. It is an object of the present invention to provide two new structures (hereinafter, referred to as a first structure of the present invention and a second structure of the present invention) that can be performed.

The wall panel 12 is formed by directly adhering a surface building material 5 such as a tile to the surface of a board-shaped base 12a having a predetermined thickness. The base 12a is formed of an inorganic material such as cement as a raw material, and an extrusion molding method or the like is applied to its manufacture. The thickness of the base 12a is determined by the upper surface 7 of the rising edge 7a of the waterproof pan 7.
In order to keep the placement relationship with respect to b (relationship between the surface building material 5 and the rising edge 7a) and the like,
It is almost the same as the conventional holding frame 3 (see FIG. 10). A plurality of grooves 13, 13, ... Are provided on the back surface (front side surface in FIG. 1) of the base 12a of the wall panel 12 as a measure for reducing the overall weight of the wall panel 12. Therefore, a ridge is left formed between the respective grooves 13, 13, ... However, in the first structure of the present invention, this ridge is attached to the attachment projection 2 for attaching the couplers 15, 18.
It was used as 1, 2, ... Since the groove 13 on the back surface is not an essential structure for the wall panel 12, the attachment protrusion 21 is rather the wall panel 12 instead.
It should be said that the groove 13 is formed between the attachment protrusions 21, 21, ... As a result, the protrusion 13 is formed so as to project toward the back surface thereof. In this embodiment, the cross-sectional shape of the attachment protrusion 21 (virtual cross section of the groove 13) is dovetail-shaped. Further, the groove 13 is provided over the entire height of the base 12a, and the upper end surface and the lower end surface of the wall panel 12 are provided with opening portions having the same shape as the virtual cross section of the groove 13. (The opening portion is used as insertion ports 14, 14, ... For inserting the coupling tools 22, 25 in the second structure of the present invention described later). The surface building material 5 adhered to the surface of the base 12a may be natural stone, metal, plastic, or other small pieces, or a suitable decorative material, in addition to the tile.

FIG. 2 shows a coupling tool 15 used for coupling the wall panel 12 and the horizontal plate for the floor (waterproof pan 7).

At this time, in order to facilitate the insertion of the coupling tool 15, it is convenient to give a chamfered radius as shown by a chain double-dashed line in FIG. 2 to the upper end corners of both the claw pieces 16, 16. Further, as shown in FIG. 4, when the front surface gap X and the side surface gap Y with respect to the attachment projection 21 are provided on the inner surface of the coupling tool 15, the outer shape error associated with the wall panel 12 in manufacturing is absorbed. It is possible and convenient. As shown in FIG. 1, the connector 1
When the attachment of 5 is completed, the hook portion 1 of the coupling tool 15
By hooking 7 on the rib 7c of the waterproof pan 7,
The wall panel 12 is joined to the waterproof pan 7. It is needless to say that the attachment pitch and the number of attachments of the coupler 15 may be increased or decreased according to the size and weight of the wall panel 12.

On the other hand, a connecting tool 18 used when connecting the wall panel 12 and the horizontal plate for the ceiling (ceiling panel 2).

The main body portion 18a includes a hook portion 20 that is formed so as to project upward from the back surface side. Further, the bent portions on the front side of the main body portion 18a so as to face each other are used for attaching to the wall panel 12, and the holding claw pieces 19, 1 are used.
It is supposed to be 9. When a chamfered radius (refer to a chain double-dashed line) for facilitating the attachment of the wall panel 12 to the attachment projections 21 and 21 is applied to the claw pieces 19 and 19, the claw pieces 19 and 19 are used. Shall be applied to the lower corners of the. The reason for this is that the connecting member 18 is to be inserted from the insertion ports 14 and 14 which are opened at the upper end surface of the wall panel 12 to the lower side thereof (see FIG. 1). Further, the hook portion 20 of the coupling tool 18 is formed so as to be inserted into the folding edge 2a of the ceiling panel 2 and hold and hold it. Therefore, after the ceiling panel 2 is supported on the upper end surface of the wall panel 12, the attachment protrusions 21, 21 of the wall panel 12 are supported.
By inserting the connector 18 into the (insertion ports 14, 14), the engagement between the wall panel 12 and the connector 18 and the engagement between the connector 18 and the ceiling panel 2 can be performed reliably and easily. Becomes
