[Problems to be Solved by the Invention]
In the one described in Japanese Patent No. 40324, since the frame is made of "C" shaped steel having slits, it is weak in the twisting direction, so that the strength is low and there is a problem in durability. Therefore, in order to prevent this decrease in strength, reinforcement has been conventionally performed, which causes a problem that it is troublesome, productivity is poor, and weight is increased.

Further, in the one disclosed in Japanese Utility Model Laid-Open No. 63-179313, there is a problem that a clamp has to be manufactured separately in addition to the clamp receiver, and further, the end portions of the wall panel are connected to each other. There is a problem in that the rigidity of the joint is low because the clamp receiver is made of an elastic plate and is engaged with the clamp. The present invention has been proposed in view of the above problems, and has an object to provide a wall panel connection structure that has a simple structure without lowering productivity and that can sufficiently enhance the rigidity of the joint. That is the purpose.

[0005]

In order to achieve the above object, a wall panel connection structure according to the present invention is a wall panel in which side edge portions are juxtaposed with each other to form a side wall of a chamber. The wall panel is composed of a frame formed of a member having a rectangular closed cross section and a decorative plate stretched on one side of the frame. Inside, the locking screw is fixed to the surface along the side-by-side operation direction of the wall panels and on the surface on the side away from the side edge of the adjacent frame in a state in which its head projects from the surface portion of the frame, An engaging piece made of an elastic plate material whose tip portion wraps around from the other frame to the head of the locking screw is provided, and the tip of the engaging piece is fitted to the head of the locking screw. Form a combined recess and fit when the wall panels are operated side by side. It is characterized in that the edges between the use recess adjacent panels fitted to the head of the screw for hooking has to be connected.

[0006]

In the wall panel connection structure of the present invention, when one wall panel is juxtaposed, one frame forming the side edge portion of the adjacent wall panel is preliminarily provided with a locking screw, the head of which is a surface portion of the frame. Securely fix it so that it protrudes from. Next, an engaging piece made of an elastic plate material whose tip portion wraps around from the other frame at the height position corresponding to the head of the locking screw to the head of the locking screw is provided, and the locking screw is fixed. While making the side edges of the wall panel and the wall panel provided with the engaging pieces adjacent to each other,
When operated in the juxtaposed direction, the fitting recesses of the engaging pieces are securely fitted to the heads of the locking screws, and the side edges of the two wall panels are securely connected to each other.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a connecting portion of a wall panel forming a side wall of a unit room such as a prefabricated bathroom. In the drawing, reference numeral 1 is a side-by-side arrangement in which end edges are adjacent to each other, and a connector 2
Shows wall panels connected by.

Although not shown in the drawing, the wall panel 1 is entirely omitted, but a frame 4 is formed by framing a rectangular pipe 3 having a closed cross section, and a waterproof decorative plate 5 is provided on the front surface of the frame 4. Is formed by sticking. The connecting tool 2
Is composed of an engagement piece 6 to be described later and a locking screw 7 with which the tip end of the engagement piece 6 is engaged.

That is, as shown in FIG. 2, the engaging piece 6 is formed by bending a plate material having elasticity into a substantially U-shape by opening a length D which is about twice the width H of the rectangular pipe 3. A short contact portion 8 is formed at one end and an engagement portion 9 is formed at the other end. A screw hole 11 for inserting a fixing screw 10 is provided at a portion of the back portion 6a near the contact portion 8. Has been drilled. This engaging part 9
The fitting recess 12 is bent so as to fit the head 7a of the locking screw 7, which will be described later, and the tip of the fitting recess 12 has an inclined guide surface 13 that is folded back outward. Has been formed.

Further, as shown in FIG. 3, the locking screw 7 forming the connecting tool 2 is formed by a tapping screw having a round head 7a. Next, the case where the wall panel 1 is connected using the connecting tool 2 configured as described above will be described. First, as shown in FIG. 2, a screw hole 11 is formed in the back portion 6a of the engaging piece 6.
The fixing screws 10 inserted through the wall panel 1 installed side by side
The engaging piece 6 is screwed to the frame 4 of the one wall panel 1
To fix.

Next, as shown in FIG.
Of the frame 4 forming the other wall panel 1 arranged side by side,
Side part 3 of the rectangular pipe 3 facing the inner side of the frame 4
At a, it is screwed into a position substantially corresponding to the engaging piece 6. Then, the wall panel 1 to which the locking screw 7 is fixed and the engaging piece 6
4 and FIG. 1 are operated in a state in which the side panels are in contact with each other in the side-by-side direction indicated by arrow A in FIG.
When the decorative plates 5 and 5 are substantially flush with each other, the inclined guide surface 13 at the tip of the engaging piece 6 attached to the frame 4 of the one wall panel 1 moves to the other wall panel 1 during this operation. After climbing on the locking screw 7 fixed to the frame 4,
As shown in FIG. 4, the fitting recessed portion 12 is fitted into the head portion 7a of the locking screw 7, and the side edge portions of the wall panel 1.1 are securely connected to each other. The connection work of No. 1 is completed.

The connection of the wall panels 1.1 described above is a case where the wall panels 1.1 are arranged side by side in the same plane. For example, in order to form a corner, the wall panels 1.1 are in a substantially right angle state. When they are installed in parallel with each other, they are arranged as shown in FIG. That is, since the decorative board portions 5 and 5 are arranged at a substantially right angle in a state of being close to each other,
In order to bridge the engagement pieces 6 across the frames 4 and 4 which are positioned with a space therebetween, the engagement pieces 6 are formed in a substantially "W" shape in plan view, and the points are the above-mentioned engagement pieces 6 The other configurations and operations are the same as those described above.

In this case, as shown by an imaginary line Y in the drawing, the intermediate portion formed in a substantially "W" shape may be short-circuited. In such a case, the short-circuited portion functions as a beam, so that the rigidity of the corner can be improved. In addition, the reference numeral 19 in FIG.
This is an angle for backing up the filler 20 filled in between.

Further, in the above embodiment, the head 7a of the locking screw 7 is formed by a round head tapping screw, but instead of this, a square bolt or a hexagon socket head bolt can be used. In this case, the fitting recess 12 of the engagement piece 6
Will be formed into a substantially U-shape when viewed from above.

[0015]

As described above, in the wall panel connection structure according to the present invention, the wall panel is stretched to one side of the frame and the frame formed of a frame having a rectangular closed cross-section. Since the frame is made of a decorative plate, the rigidity of the frame is high, and the strength of the wall panel does not decrease due to the slit, as in the case of the conventional frame made of "C" shaped steel having slits. As a result, productivity can be significantly improved by eliminating the conventional troublesome reinforcement, and the advantage that the structure for reinforcement can be complicated and the increase in weight can be prevented. is there.

Further, the wall panel having the locking screw fixed to the frame and the wall panel having the engaging piece provided on the frame are operated in a side-by-side direction with their side edge portions adjacent to each other, and Firmly fit the fitting recess into the head of the locking screw,
Since the side edge portions of both wall panels are connected to each other, compared to the case where the side edge portions of both wall panels are connected by engaging the clamp receiver and the clamp, a clamp other than the clamp receiver is used. There is an advantage that the connection structure of the partition wall panel can be made inexpensive because it does not have to be separately manufactured.

Furthermore, since the engaging pieces are securely fitted to the heads of the locking screws to connect the side edge portions of both wall panels, the end portions of the wall panels can be connected to each other. Compared with the conventional joint structure of the wall panel, which is performed by the engagement between the clamp receiver formed of the elastic plate material and the clamp, there is almost no elastic deformation at the joint portion, and the rigidity can be significantly improved. There is also.
