Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a ceiling panel interconnecting device that constitutes a ceiling wall by connecting to each other on a side wall of a sanitary facility room.

[Prior art and its problems]

Conventionally, this type of ceiling panel interconnection device is shown in FIGS. 6 to 7.

In this prior art, when a ceiling wall (a ₁ ′) is assembled, the ceiling panel (a ₁ ) whose end faces are in abutting relationship with each other have a L-shaped cross section over the entire length of the upper end portion near the end face (a ₁ ). 1)
(1) is fixed, and the ceiling panels (a ₁ ) are arranged in a river shape, that is, in parallel on the side wall (a ₂ ) of the sanitary facility room (A), that is, the adjacent shape members (1) The ceiling wall (a ₁ ′) is assembled and formed by fastening (1) with the fastening metal fitting (2) with the sealing material (3) (foamed polyethylene) interposed.

By the way, such as lighting to change the atmosphere of the mirror and the room,
Many customers want to install a new ceiling wall (a ₁ ′).

However, according to the prior art, when a new mirror body or lighting is installed,
As shown in FIG. 7, the tip of the water sealing material (3) interposed between the mold materials (1) and (1) is deformed into a V shape, and the standing piece (4) of the mold material (1) (1) is deformed. ) (4) is locally pressed to cause settling, which lowers the water sealing function, and the clamping force of the clamping metal fittings (2) for connecting the mold members (1) and (1) to each other. (1) Although the structure is such that the connection strength is exhibited by the rigidity of (1) (L-shaped material), the fastening metal fitting (2) is buckled or deformed due to long-term use, and the shape material (1) (1)
However, since it is plastically deformed and the ceiling wall (a ₁ ′) cannot be stably maintained in a flat plate shape, the ceiling wall (a ₁ ′) is gradually bent and deformed, which is dangerous, and there is a problem that the customer's request cannot be dealt with.

By the way, the fastening with the fastening metal fittings (2) is done by the mold material (1) (1).
Although it is performed at equal intervals over the entire length, it is an artificial work, and the tightening torque is subtly different in each tightening metal fitting (2), and wrinkles and partial overlaps are formed on the water sealing material (3). Therefore, there are many cases in which small through holes that are difficult to distinguish between the ceiling panels (a ₁ ) and (a ₁ ) are forced to be generated, and the ceiling space direction of the downlight suspended on the ceiling wall (a ₁ ′). There is also another problem that the leakage of radiation to the inside is directly seen from the room (sanitary equipment room) through the small through hole, and the usability is impaired.

[Technical issues]

 The technical problems of the present invention are as follows.

To increase the strength of connection between ceiling panels, to prevent the sealing material between ceiling panels from sagging (the property of eliminating the repulsive force) even when the bending deformation force acts on the ceiling walls, and between the ceiling panels In addition, even if a small through hole is formed due to the imbalance of the tightening torque in the tightening fitting, the leakage of radiation into the ceiling space should not be visually recognized from the room (sanitary equipment room).

[Technical means]

The technical means taken to achieve the above technical problem is to fix the connecting metal fittings to the upper end portions of the ceiling panels in the vicinity of the end surfaces of the ceiling panels where the end surfaces are in abutting relationship with each other, and the connecting metal fittings are provided next to each other. In the ceiling panel, the first mold member fixed to one of the upper end portions near the end faces in abutting relationship with each other and the second mold member fixed to the other end member are provided on the extension of the ceiling panel end face. The rising piece is provided over the entire length, and the second mold member is formed on the extension of the ceiling panel end surface and has a hook-shaped hooking piece over which the tip of the standing piece engages at the tip. That is.

[Action]

 The operation of the technical means of the present invention is as follows.

The first mold member fixed to one of the upper surface end portions near the end faces of the ceiling panels whose end faces are in contact with each other and the second mold member fixed to the other end are Connection is made with a connection strength in which the engaging force between the standing piece and the hooking piece of the second mold material and the rigidity of both mold materials are synergistic.

Even if a flexural deformation force is generated on the ceiling wall, the tip of the water sealing material interposed between the standing members of the first mold member and the hook-shaped hooking member formed to rise on the second mold member are interposed between the mold members. The crushing force acting on is minimized.

The hook-shaped hooking piece of the second mold member covers the portion directly above the connection portion between the ceiling panels and prevents the irradiation light leaking into the ceiling space from entering through the small through-hole formed at the connection portion of the ceiling panel.

[Effect of device]

Since the present invention is configured as described above, it has the following advantages.

The ceiling panels are connected to each other by cooperation of the tightening force of the tightening metal fittings, the engaging force between the standing piece of the first mold material and the hooking piece of the second mold material, and the rigidity of both mold materials, and the mirror body or another lighting The ceiling panel can be connected with a connection strength that does not cause bending deformation even if the equipment and equipment required by the customer are attached.

Since the tip of the standing piece of the first mold material and the hooking piece of the second mold material are engaged with each other on the sealing material between the ceiling panels, when the fixtures and fixtures are attached to the ceiling wall, the engaging force is used to seal the water. Prevents excessive crushing of the material and does not cause fatigue.

The hook-shaped hooking piece of the second mold member covers the portion directly above the ceiling panels and prevents the leakage of light from the ceiling sky, so that the user does not feel discomfort.
