[0001]

[Industrial applications]

 The present invention relates to a connection structure for wall panels forming a side wall of a unit room such as a unit bath, and more particularly to a connection structure for a projecting corner.

[0002]

[Prior Art]

 For unit rooms such as unit baths, standardized wall panels for side walls, floor panels (floor pans), ceiling panels, etc. are produced in advance at the factory, and these are easily assembled on-site through connecting members. It can be formed into. Then, as a connection structure capable of easily connecting the wall panels to each other, for example, as shown in FIG. 5, a frame 102 is provided opposite to the back surface of the wall panel 101, and the frame 102 is connected so as to embrace the frame 102. A structure in which a metal member 103 is provided and a wedge 104 is driven between the front surface of the wall panel 101 and the frame 102 (see Japanese Utility Model Laid-Open No. 62-155107), or one wall panel 201 as shown in FIG. The fixing member 204 of the hook-type clamp 203 is fixed to the frame 202 provided along the back surface of the frame with the screw 205, and the frame 202 of the other wall panel 201 is provided adjacent to the fixing member 204 of the clamp 203. There has already been proposed a connection structure such as a structure (see Japanese Utility Model Laid-Open No. 11914/1990) adapted to be attached to the member 206.

[0003]

[Problems to be solved by the device]

 However, the above connection structure has the following problems. That is, in the structure of FIG. 5, since the wedge 104 is driven between the wall panels 101, there is a problem that it cannot be applied to the projecting corner structure. On the other hand, the structure of FIG. 6 cannot be applied to the projecting corner structure, and for example, even if only one wall panel 201 is to be removed in order to pass a pipe or the like through the space on the back side of the panel, it is fixed. Since the screw 205 for fixing the member 204 to the frame 202 cannot be unfastened from the inside of the room, it may be said that even the adjacent wall panel 201 must be removed, which leads to poor workability and the spring force of the movable member 206. However, since the frame 202 of the one wall panel 201 is fixed, there is a problem in the fixing force of the wall panel 201. 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 the desired connection state may not be obtained.

In view of such circumstances, the present invention is firmly assembled only by the work from the inside of the room, is easy to remove, can reduce the gap of the connecting portion, and can accurately produce the desired corner. It is an object of the present invention to provide a wall panel connection structure capable of forming a structure.

[0005]

[Means for Solving the Problems]

 In order to achieve such an object, the projecting corner wall panel connecting structure of the unit room according to the present invention comprises two wall panels, each of which is provided with a corner material having a corner part formed at a desired projecting angle. The end face of the wall panel is brought into close contact with the end face of the corner member and sandwiched from both sides, and the interior surface of the wall panel is arranged to be flush with the interior face of the corner member. The upper end of the frame along the side of the frame has locking projections protruding from the surface opposite to the corner material, and is detachably locked in the notch grooves of the locking pieces extending from both sides of the fixing bracket. The wedge is press-fitted into the gap between the intermediate portion of the fixed metal fitting and the frame from above.

Further, according to a second aspect of the present invention, the back surface side edge of the wall panel is notched, and the frame is provided closer to the center of the wall panel than the notched portion. If necessary, the gap between the corner material and the wall panel may be filled with a silicone caulking material or the like as a sealing material.

[0007]

[Action]

 According to the above configuration, first, the two wall panels are arranged with the corner member sandwiched from both sides so as to be flush with the surface forming the corner of the corner member. In addition, the end surface of the corner material and the end surface of the wall panel should be in close contact with each other. Then, insert a hand between the wall panel and the building wall surface over the upper edge of the wall panel from the indoor side to lock the locking piece of the fixing bracket to the locking projection.

Next, a wedge is driven into the gap formed between the fixing metal member and the frame from above and press-fitted. When the wedge is pressed in, force is applied to the locking piece of the fixing bracket in the direction away from the wall panel, so that the side wall surface of the locking protrusion and the inner wall surface of the cutout groove are pressed together to prevent the fixing bracket from coming off. With the corner material sandwiched between the wall panels, it can be securely connected with the desired corner angle.

On the other hand, when it is necessary to pass piping between the wall panel and the building wall surface and the side wall panel has to be removed once, the ceiling panel or the like is removed and the upper portion of the wall panel to be removed is opened. After that, insert your hand or a tool from the top of the wall panel, hold the upper edge of the wedge, and remove the wedge. Then, the desired wall panel can be removed by removing the fixing fitting from the locking protrusion.

When the unit room is a bathroom using water or the like, it is necessary that at least the contact surface of the corner material with the wall panel is made of an elastic material having a high waterproofness.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the drawings showing an embodiment thereof. FIG. 1 is a perspective view of a wall panel connecting portion at a corner of a bathroom unit as seen from the rear side, and FIG. 2 is a cross section as seen from above, as an embodiment for explaining a wall panel connecting structure according to the present invention. It is represented.

As shown in FIGS. 1 and 2, in this embodiment, a corner material having a corner portion 21 formed at a desired projection angle 8 (135 ° in this embodiment) in a portion where a projection structure is required. 2 are arranged, and two wall panels 1 and 1 are vertically installed so as to sandwich the corner member 2. In the case of vertical installation, the end face 1a of the wall panel 1 is brought into close contact with the side wall face 2a of the corner member 2, and the surface of the wall panel 1 (inside the room) is flush with the surface of the corner member 2. So that

The wall panel 1 is formed of a decorative material 11 made of marble on the indoor side, and a base material 12 is integrated on the back surface thereof. A frame 13 is provided on the base material 12 along the vertical direction of the wall panel 1. The corner material 2 has a surface portion formed of a material having high watertightness and elasticity (for example, butyl rubber). That is, by simply bringing the side wall surface 1a of the wall panel 1 into close contact with the side wall surface 2a of the corner member 1, the two wall panels 1 and 1 have a predetermined projecting angle, and the inside and outside can be separated into a watertight state. It is like this.

The opposing frame 13 of both wall panels 1, 1 is provided with a locking projection 14 near the upper edge thereof. The locking protrusion 14 is composed of a locking portion 14a and a head portion 14b having a diameter larger than that of the locking portion 14a. The locking portion 14 a of the locking projection 14 is engaged with the notch groove 32 formed in the locking piece 31 of the fixing fitting 3.

It is preferable that at least one of the locking pieces 31 of the fixing fitting 3 always has elasticity for urging toward the frame 13 side, and examples of the material thereof include stainless steel. Next, the connection method will be described. First, the two wall panels 1 and 1 are arranged on both sides of the corner member 2 so that the end faces 1a are in close contact with the side wall faces 2a of the corner member 2. Next, from the indoor side, the fixing metal fitting 3 is inserted between the wall panel 1 and the inner wall surface (not shown) of the wall panel 1, 1 or the corner member 2 and the both frames 13 are held by the locking pieces 31. Let Then, when the fixing metal fitting 3 is pushed downward in this state, the fixing metal fitting 3 is lowered along the frame 13 and the locking portion 14a of the locking projection 14 is engaged with the notch groove 32.

Next, after this engagement is completed, the wedge 5 is inserted from above the wall panel 1 and the tip thereof is inserted into the gap 6 formed between the fixing metal fitting 3 and the frames 13, 13. After that, the head of the wedge 5 is driven in the direction of the gap 6 with a hammer or the like. By driving the wedge 5 into the gap 6, the locking pieces 31 of the fixing fitting 3 are pulled in the directions of the arrow A and the arrow B, respectively. The locking portion 14a and the outer peripheral surface are pressed into contact with each other, and the two wall panels 1 and 1 are firmly fixed in a state of having a predetermined projecting angle. Further, even if the locking piece 31 expands outward, the locking piece 31 is locked by the head portion 14b of the protrusion 14 and the expansion is prevented.

In the figure, 7 is a silicon caulking material as a sealing material, and after the above connection is completed, it is filled in a gap between the wall panel 1 and the corner material 2 from the indoor side, if necessary. The watertightness can be improved and the corner material 2 can be prevented from coming off. On the other hand, when disconnecting, the ceiling panel (not shown) is removed, and a hand or a jig is inserted 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 and pulling the wedge 5 upward to release the pressure contact between the outer peripheral surface of the locking portion 14a and the inner wall surface of the cutout groove 32, the engagement of the locking projection 14 with the cutout groove 32 is released, and the fixing bracket 3 is released. If removed, the connection of the wall panel 1 can be disassembled only by working from the inside of the room.

FIG. 3 is a sectional view showing another embodiment of the projected corner wall panel connection structure according to the present invention when viewed from above. In the wall panel connection structure of the present embodiment, the base material 12 of the wall panels 8 and 8 has a width narrower than that of the decorative material 11 on the front surface, and the back side edge of the wall panel 8 is cut out in a stepwise manner. In addition, the same as the first embodiment except that the frame 13 is provided along the end face of the base material 12, that is, at a position that is closer to the center side than the cutout 81 of the wall panel 8. It has become. In the figure, 16 is a metal reinforcing member that prevents the end of the decorative material 11 protruding laterally from the base material 12 from being damaged during transportation.

According to the wall panel connection structure of the present embodiment, as shown in the figure, a desired corner structure can be achieved even with a small corner material 9, and the interior decoration can be further enhanced. . 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. 4, in the fixing member 3, at least one of the locking pieces 31 has elasticity so as to be separable and contactable in the frame 13 direction, and both locking pieces 31 have heads of the protrusions 14. An elongated hole 38, which is narrower than 14b and wider than the locking portion 14a of the protrusion 14, is provided as a notch groove on the horizontal surface, and the head 14b of the protrusion 14 is located on the intermediate portion 36 side of the fixing fitting 3 of the elongated hole 38. A structure in which a hole 37 having a larger diameter is provided may be used. With such a structure, after inserting the protrusion 14 of one frame 13 into the hole 37 of the non-elastic side locking piece 31, the elastic locking piece 31 is moved away from the other frame 13. The protrusion 14 of the other frame 13 is inserted into the hole 37 of the locking piece 31 while pushing and expanding in the direction. Then, if the wedge 5 is driven into the gap between the frame 13 and the fixing metal fitting 3, the fixing metal fitting 3 slides and the locking portion 14a of the projection 14 enters the long hole 38 as shown in the figure, and the engaging portion 14a is engaged.
