DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connection structure of a ceiling panel which forms a ceiling wall by connecting with each other on a side wall of a sanitary equipment room such as a bathroom unit.

[0002]

2. Description of the Related Art Conventionally, as a connection structure of a ceiling panel constituting a ceiling wall on a side wall such as a wall panel of a bathroom unit, there is known a structure described in Japanese Utility Model Application Laid-Open No. 2-47353.

FIG. 6 shows a conventional connection structure of a ceiling panel.
As shown in the above, when the ceiling wall a is assembled on the side wall of the sanitary equipment room, the end surfaces of the ceiling panels b, which are in abutting relationship with each other, are over the entire length of the upper surface end near the end surface thereof.
A first mold member c and a second mold member d which are engaged with each other are fixed, and the ceiling panels b are arranged side by side on the side wall of the sanitary equipment room in parallel, and the adjacent first mold member c and second mold member d are arranged. Are interlocked with a water sealing material (foamed polyethylene) interposed therebetween, and fastened with a fastener e to assemble and form a ceiling wall a.

[0004]

However, in the conventional ceiling panel connection structure, as described above, the adjacent first and second mold members c and d are engaged with each other via a sealing material (polyethylene foam). Then, when the tightening torque is strongly applied to each of the fasteners e, a concentrated load is applied and the connection part is deformed, and a step is formed on the ceiling surface of the connection part. The appearance may be unsightly. In addition, the work of engaging the ceiling panels b and then fastening the first and second mold members c and d through the fasteners e is troublesome behind the ceiling. Furthermore, it is necessary to bond and fix each of the mold members c and d to the ceiling panels b in advance, which increases the number of parts and the number of parts and increases the material cost.

In view of such circumstances, the present invention provides a ceiling panel connection structure which is excellent in appearance without producing a step or the like in a connection portion of the ceiling panel, and is simple in connection work and requires a small number of parts. It is intended to provide.

[0006]

In order to achieve such an object, a connection structure for a ceiling panel according to the invention of claim 1 (hereinafter referred to as a "connection structure for a ceiling panel of claim 1").
Is provided with a connection groove that opens outward at one end of one ceiling panel, and a bent piece that projects outward is provided at one end of the other ceiling panel. The connector comprises a joint fitting portion of a ceiling panel formed by fitting a bent piece into the connection groove, and a holding tool having an insertion groove formed by holding pieces protruding from both sides of the substrate. The connection fitting portion is inserted into the insertion groove of the tool.

In the connection structure for a ceiling panel of the first aspect, the material of the ceiling panel is not particularly limited, but a backing material such as a PVC steel plate and a gypsum board adhered to the back surface of the PVC steel plate is preferable.

In the above-mentioned connection structure for a ceiling panel, the shape of the holding member is a spring steel plate bent and formed to have a U-shaped cross section or the tip of the holding piece curved inward. You may.

Further, the ceiling panel connection structure according to the invention of claim 2 (hereinafter referred to as “ceiling panel connection structure of claim 2”) is the same as the ceiling panel connection structure of claim 1. A screw is inserted into the attachment through each of the holding pieces, and the opening width of the insertion groove is adjusted by tightening the screw to the holding piece.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention will be described below in detail with reference to the drawings. 1 to 5 show an embodiment of a ceiling panel connection structure according to the present invention.

As shown in FIG. 1, ceiling panels A, A
An outer flange 3, which is made of a PVC steel plate 1 and a gypsum board 2 stuck to the back surface of the PVC steel plate 1 and protrudes outward from one side end of the ceiling panel A, is once bent at a right angle. A connection groove 4 that is folded back to the side A and opens outward is formed. The tip 5 of the connection groove 4 is located at the outermost position. The outer flange 6 protruding outward from one side end of the other adjacent wall panel A is once bent at a right angle, and further bent outwardly in the horizontal direction to form a horizontal piece 7. Is bent downward to form a hanging piece 8, whereby a bent piece 9 protruding outward is formed. Horizontal piece 7
The tip 81 of the hanging piece 8 comes into contact with the connection groove 4.

The outer panels 3, 6 abut against the wall panels A, A,
The hanging piece 8 is fitted into the connection groove 3 while the horizontal piece 7 presses the tip 5 of the connection groove 4 to form the joint fitting portion B.

In the ceiling panel connection structure of the present invention, a clip 10 is attached to the joint B as shown in FIG. As shown in FIG. 2, the holding member 10 is formed by bending a short piece of a spring plate material, and is bent downward from both sides of the substrate 11 to protrude the holding members 12 and 12 a. One of the holding pieces 12 is bent inward at the tip, the other holding piece 12a is bent inclining inward and the tip is slightly bent outward, so that the holding piece 12 The insertion groove 13 is formed so as to face the piece 12a. The ceiling panel A is inserted into the insertion groove 13 of the clipping tool 10 so as to clamp the joint B.

FIG. 3 shows another embodiment of the ceiling panel connection structure according to the present invention. In the ceiling panel connection structure shown in FIG. 3, the clip 20 is attached to the joint fitting portion B. As shown in FIG. 4, the clip 20 is formed by bending a short piece of a spring plate material.
Are bent downward at right angles from both sides thereof, and insertion pieces 22 and 22a are protruded, and insertion grooves 23 are formed so that the insertion pieces 22 and 22a face each other. One holding piece 22 is provided with a screw hole 24 in the vicinity of the substrate 21, and the other holding piece 22 a is provided with an insertion hole 25.
Is screwed into the screw hole 24 such that the screw tool 26 penetrates through the insertion hole 25.

In order to connect the adjacent ceiling panels A, A by using the clipping device 20, as shown in FIG. Wall panels C surrounding the periphery of the waterproof pan and ceiling panels A, A covering the rectangular upper opening formed by the wall panels C, are arranged side by side, and the flanges 3, 6 are connected to each other. To form a joint fitting portion B, and fix the peripheral portions 30, 60 of the ceiling panels A, A to the upper end portions of the wall panels C. At this time, the user enters the back side of the ceiling panel from the inspection opening D, leans out of the upper body, and inserts the holding member 20 into which the screw 26 has been previously screwed through the joint fitting portion B of the ceiling panels A, A. By inserting into the insertion groove 23 and turning the screw 26 in the screw tightening direction, the opening width of the insertion groove 20 is reduced, and the flanges 3 and 6 at the connection part of the ceiling panel can be brought into close contact. .

[0016]

As described above, the connection structure of the ceiling panel according to the present invention is constructed as described above, so that the connection portion of the ceiling panel is not deformed and a step is formed on the ceiling surface of the connection portion. It is excellent. In addition, it can be connected simply by attaching the clipping tool to the joint fitting portion with one touch, and can be easily installed by anyone. Moreover, since the number of parts is small, the number of construction steps is small, and the manufacturing cost can be reduced.

In particular, according to the configuration of claim 2, furthermore,
There is no need to insert screws after the ceiling panels come into contact with each other, and it is possible to easily connect them without any gaps only by tightening screws. Therefore, construction workability is better,
Cost reduction can also be achieved.
