BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connection structure of a wall panel forming a side wall of a unit room such as a unit bath, and more particularly to a connection structure of a corner.

[0002]

2. Description of the Related Art In a unit room such as a unit bath, a standardized wall panel, a floor panel (floor pan), a ceiling panel, etc. for a side wall are produced in a factory in advance, and these are produced on site through connecting members and the like. It can be easily formed by assembling. As a connection structure that can easily connect the wall panels to each other, for example, as shown in FIG. 4, a frame 102 is provided opposite to the back surface of the wall panel 101, and the connection hardware 103 is held by holding the frame 102.
And a wedge 104 is driven between the frame 102 and the front surface of the wall panel 101 (see Japanese Utility Model Application Laid-Open No. 62-15 / 1987).
5107) and a frame 202 provided along the back surface of one wall panel 201 as shown in FIG.
The fixing member 204 of the hook type clamp 203 to the screw 20
5 and the frame 202 of the other wall panel 201 is engaged with a movable member 206 provided adjacent to the fixing member 204 of the clamp 203 (see FIG. 2).
A connection structure as shown in JP-A-11914 is already proposed.

[0003]

However, the above connection structure has the following problems. That is, in the structure of FIG. 4, since the wedge 104 is driven between the wall panels 101, the structure cannot be applied to the corner structure and the wedge 104 is inserted from the front. There is a problem that the space between the wall 101 and the wall panel 101 is too wide, and the appearance is poor when viewed from the indoor side.

On the other hand, in the structure shown in FIG. 5, the fixing member 204 is fixed to the frame 202 even if only one wall panel 201 is to be removed in order to later pass a pipe or the like into the space on the back side of the panel. Because the screw 205 cannot be unfastened from the indoor side, it may be necessary to remove even the adjacent wall panel 201, and the workability is poor, and the frame of one wall panel 201 is moved by the spring force of the movable member 206. The wall panel 2
01 has a problem with the fixing force. Moreover, in this structure, when the frame 202 is fitted to the movable member 206, a large load is applied to the clamp 203, and the clamp 203 may be deformed and a desired connection state may not be obtained.

In view of such circumstances, the present invention can be assembled firmly only by working from the indoor side, can be easily removed, can reduce the gap of the connecting portion, and can accurately obtain the desired corner structure. It is an object of the present invention to provide a connection structure of a wall panel that can form a wall panel.

[0006]

According to the present invention, in order to achieve such an object, a connection panel for a corner wall of a unit room according to the present invention is arranged such that two wall panels substantially contact an edge on the indoor side. And a spacer having two wall surfaces having a desired crossing angle is interposed between the two wall panels so that the wall surface is in close contact with the side wall surface of the wall panel, and extends along the vertical direction of the rear surface of the wall panel. At the upper end of the provided frame, a locking projection protruding from a surface opposite to the spacer is detachably locked in a notch groove of a locking piece extending from both sides of the fixing bracket, Further, the wedge is press-fitted into the gap between the intermediate portion of the fixing bracket and the frame from above.

[0007]

According to the above construction, first, two wall panels are
A spacer having a wall surface having a crossing angle corresponding to a desired corner angle is interposed between the spacers so that the indoor side edge thereof is substantially in contact. In addition, the end face is brought into close contact with the wall surface of the spacer. Thereby, both wall panels are accurately positioned so as to form a desired corner angle.

Then, a hand is inserted between the wall panel and the wall surface of the building from the indoor side over the upper edge of the wall panel to lock the locking piece of the fixing bracket to the locking projection. Next, a wedge is driven from above into a gap formed between the fixing bracket and the frame and press-fitted. Since the locking piece of the fixing bracket receives a force in the direction away from the wall panel by press fitting of the wedge, the side wall surface of the locking projection and the inner wall surface of the notch groove are pressed against each other, so that the detachment of the fixing bracket can be prevented. The wall panels can be securely connected with the desired corner angles.

On the other hand, when it is necessary to pass piping or the like between the wall panel and the building wall, and the wall panel must be removed once, the ceiling panel and the like are removed and the upper part of the wall panel to be removed is opened. After that, insert your hand or tool from the top of the wall panel, hold the top of the wedge and remove the wedge. Then, a desired wall panel can be removed by removing the fixing bracket from the locking projection.

When the unit room is a bathroom or the like using water or the like, it is necessary to cover the wall surface of the spacer with an elastic material having a high waterproof property.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings showing embodiments thereof. FIG. 1 is a perspective view of a connecting part of a wall unit in a corner part of a bathroom unit when viewed from the rear side, and FIG. 2 is a cross-sectional view when viewed from above as an embodiment for explaining a connecting structure of a wall panel according to the present invention. It shows.

As shown in FIGS. 1 and 2, in this embodiment, two wall panels 1 and 1 are suspended from a portion forming a corner with a spacer 2 interposed therebetween. In the vertical installation, the side wall surface 1a of the wall panel 1 is brought into close contact with the surface 21 of the spacer 2, and the edge of the wall panel 1 is brought into close contact. The interior side of the wall panel 1 is formed of a marble decorative material 11 and a backing material 12
Are integrated. A frame 13 is provided on the base material 12 along the vertical direction of the wall panel 1.

The spacer 2 is formed such that the intersection angle of the two surfaces 21 is the same as the complementary angle (45 ° in the present embodiment) of the included angle (135 ° in the present embodiment). The surface portion is formed of a material having high watertightness and elasticity (for example, butyl rubber). That is, the side wall surface 1a of the wall panel 1
By simply contacting the wall panel 21 with the surface 21, the two wall panels 1, 1 have a predetermined corner angle, and the interior and exterior can be separated in a watertight state. Note that the spacer 2 is 2
The two surfaces 21 do not need to substantially intersect, and may have a substantially trapezoidal cross section with a corner portion cut out.

Opposite frames 13 of both wall panels 1, 1
Are provided with locking projections 14 near their upper edges. The locking projection 14 includes a locking portion 14a and a locking portion 14a.
And a larger diameter head 14b. The locking projection 14 has a locking portion 14 a engaged with a notch groove 32 formed in a locking piece 31 of the fixing fitting 3.

A wedge 5 is press-fitted into a gap 6 between the fixture 3 and the frame 13. It is preferable that at least one of the locking pieces 31 of the fixing member 3 always has elasticity to urge the frame 13 side, and stainless steel or the like is used as a material. Next, the connection method will be described. First, the two wall panels 1 and 1 are arranged so as to be adjacent to each other with the spacer 2 interposed therebetween, and the fixing fitting 3 is attached from the indoor side over the wall panels 1 and 1 to the wall panel 1. And both the frames 13 are held by the locking pieces 31 by inserting the frame 13 between the frame 13 and the inner wall surface (not shown) of the building. Then, if the fixing metal 3 is pressed downward in this state, the fixing metal 3 is lowered along the frame 13 and the locking portion 14 a of the locking projection 14 is inserted into the notch groove 32.
Will be engaged.

Next, after this engagement is completed, a wedge 5 is inserted from above the wall panel 1 and its tip is inserted into a gap 6 formed between the fixing bracket 3 and the frames 13, 13. Then, the head of the wedge 5 is driven into the gap 6 with a hammer or the like. By driving the wedge 5 into the gap 6,
Since the locking pieces 31 of the fixing bracket 3 are pulled in the directions of arrows A and B, the inner wall surface of the notch groove 32 and the outer peripheral surface of the locking portion 14a of the locking projection 14 are pressed against each other. Thus, the two wall panels 1, 1 are firmly fixed with a predetermined corner angle. In addition, the locking piece 31
Is prevented by the head 14b of the protrusion 14 from spreading outward.

In the figure, reference numeral 7 denotes a silicon caulking material as a sealing material, which is filled into the gap between the wall panels 1 from the room side as required after the above connection is completed. On the other hand, when disconnecting the connection, the ceiling panel (not shown) is removed, and a hand or a jig is placed between the wall panel 1 and the building inner wall (not shown) from the indoor side over the upper part of the wall panel 1. After inserting, pulling the wedge 5 upward and releasing the pressure contact between the outer peripheral surface of the locking portion 14a and the inner wall surface of the notch groove 32, the engagement of the locking protrusion 14 with the notch groove 32 is released to fix the fixing fitting 3
Is removed, the connection of the wall panel 1 can be disassembled only by work from the indoor side.

The connection structure of the wall panel according to the present invention is not limited to the above embodiment. For example, as shown in FIG. 3, the fixing bracket 3 has at least one of the locking pieces 31 having elasticity that can be freely separated and attached in the direction of the frame 13, and both locking pieces 31 are wider than the head 14 b of the projection 14. An elongated hole 38 having a smaller width than the engaging portion 14a of the projection 14 is provided horizontally as a notch groove, and a hole having a diameter larger than the head portion 14b of the projection 14 is provided in the intermediate portion 36 of the fixing member 3 of the elongated hole 38. 37 may be provided. With such a structure, one frame 13 is inserted into the hole 37 of the locking piece 31 on the non-elastic side.
After the projection 14 is inserted, the projection 14 of the other frame 13 is inserted into the hole 37 of the engagement piece 31 while pushing the elastic locking piece 31 in the direction away from the other frame 13. If the wedge 5 is driven into the gap between the frame 13 and the fixing fitting 3, the fixing fitting 3 slides, and the locking portion 14a of the projection 14 enters the elongated hole 38 as shown in the figure, and the locking piece 31 Is locked to the projection 14,
The wall panel 1 and the wall panel can be fixed.
