2. Description of the Related Art Heretofore, a punched plate material has been used for a ceiling panel as a decoration for improving the appearance of a ceiling surface. In attaching the punched plate material to the panel frame, the plate material is welded in a state in which screws are projected upward from the periphery of the plate material, and the plate material is formed in a state in which the plate material is brought into contact with the lower surface of the frame material. Such a configuration has been adopted that the nut is tightened after the screw is passed through the hole.

By the way, in the ceiling panel having the above-described structure, the frame material of the panel frame must be formed to be somewhat wide in order to attach the plate material to the panel frame. However, if the frame material is seen through the punched holes of the plate material from the lower surface, the appearance of the ceiling surface is impaired, so a blank portion without a punched hole is formed around the plate material, but such a wide margin portion exists. By doing so, the appearance of the ceiling surface is also impaired.

There is also a ceiling panel formed by bending a plate material without using a frame material. However, when the plate material is punched and then bent, a punching hole is formed in a corner of the lower surface of the ceiling panel. And the appearance of the ceiling panel is also impaired.

[0006]

SUMMARY OF THE INVENTION In view of the above prior art, an object of the present invention is to provide a ceiling panel having a good appearance in which a punching hole is opened to the vicinity of a peripheral portion on the lower surface of the ceiling panel.

The second outer corners of the plate are fixed to the second inner corners and are urged in a direction to separate the locking portions from the second inner corners. It is pushed toward the outside. In this state, even if the flange portion has a small amount of protrusion, it is possible to sufficiently restrict the plate material from falling downward.

According to the second characteristic configuration, the mounting spring urges the pair of legs and the protruding portion in a direction of separating the pair of legs, but the pair of legs is engaged with the second inner corner. By stopping, the plate can be pressed at two places by one spring.

[0012]

As described above, according to the first characteristic configuration of the present invention, the ceiling panel can be formed even if the amount of protrusion of the flange portion is small, and the peripheral portion of the frame material which can be the above-mentioned margin portion can be sufficiently formed. Can be narrower. Further, even if punching is performed on the entire surface of the plate material, punching holes are not located at corners on the lower surface of the ceiling panel. Therefore, it is possible to provide a ceiling panel having a good appearance in which punching holes are opened to the vicinity of the peripheral portion on the lower surface of the ceiling panel.

Further, according to the second feature, the plate can be efficiently pressed with a small number of mounting springs.

Furthermore, according to the third characteristic configuration, the collar portion
By forming a first outer corner that is sharper than the second outer corner at the intersection of the lower surface of the lower part and the outer surface of the rising part, a sharper panel is formed, as compared to the case where the ceiling panel is formed by bending only the plate material. Appearance can be obtained. Moreover,
By providing a retaining means between the rising portion and the plate material to prevent the plate material from falling downward with respect to the rising portion, even if the center portion of the ceiling panel is accidentally stepped on, the plate material can be prevented from falling off. .

[0015]

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 to 4, the ceiling panel 2 according to the present invention includes a panel frame 6 formed by combining the frame members 4 in a rectangular shape, and a plate member 8 formed with a plurality of punched holes 8 b by punching. And a plate member 8 attached to the panel frame 6.

Each of the frame members 4 has a rising portion 10 extending vertically. In addition, a flange portion 12 along the longitudinal direction of each frame member 4 is protruded from a lower portion of the rising portion 10 toward the inside of the rectangle, and an intersection between an upper surface of the flange portion 12 and an inner surface of the rising portion 10. the first of the interior angle portion 14 to
While forming the lower surface of the flange portion 12 and the rising portion 10
A first outer corner 16 is formed at the intersection with the outer surface . Further, a locking portion 20 for locking one end of a mounting spring 18 described later is provided to project from the rising portion 10 toward the inside of the rectangle. Each frame member 4 is formed integrally with the rising portion 10, the flange portion 12, and the locking portion 20 by extrusion molding using aluminum or the like, and the end portions of these frame members 4 are welded to each other to form the panel frame 6. Constituting and mounting spring 18
Can be attached at any position. The frame member 4 may be formed of a metal or resin other than aluminum, or an adhesive may be used for assembling the frame members.

The plate member 8 is formed by bending each side end upward to form a second outer corner 24 and a second inner corner 22. As the plate material 8, for example, a plate thickness of 0.8 mm
Although a thin plate made of steel is used, the material is not limited to steel, and aluminum, stainless steel, plastic, or the like may be used, or a thick plate having a plate thickness of about 3 to 4 mm may be used. The punching hole 8b may be formed not only on the entire lower surface of the plate member 4 but also on a portion rising from the second outer corner 24, but in this embodiment, the formation of the punching hole 8b is stopped short of the outer corner 24. ing. Note that the punching hole 8b is not limited to a round hole, and may adopt various shapes.

The plate member 8 is fitted inside the panel frame 6 in a state where the second outer corner portion 24 comes into contact with the first inner corner portion 14. Then, the mounting spring 18 is locked to the locking portion 20 and the second inner corner portion 22, respectively, and is urged in a direction to separate the locking portion 20 and the second inner corner portion 22. The plate 8 is attached to the panel frame 6. The mounting spring 18 is formed of a line having a projecting portion 18b projecting to a side opposite to the leg portion between the pair of leg portions 18a, 18a, and the leg portions 18a, 18a and the projecting portion 18b are formed. Is a spring that urges in a direction that separates them from each other. More specifically, the mounting spring 18 is formed by bending the wire into a gentle "U" shape at the center to form the protruding portion 18b, while bending both ends of the wire to form the legs. By twisting the leg which is curved with respect to the plane to which the portion of the line that is bent in the shape of a "U", it is formed in a shape that is bent even in a side view. When the mounting spring 18 is locked, the pair of legs 18a, 18a is locked to the second inner corner portion 22, so that the second inner corner portion 22 can be pressed at two places by one mounting spring 18. It is possible.

Since the second outer corner 24 is formed by bending a steel plate, it is slightly rounded. Therefore, the step H between the lower surface of the frame member 4 and the lower surface of the plate member 8 is reduced by forming the flange portion 12 so as to be thinner toward the inside of the rectangle of the panel frame 6. The first outer corner 16 provided between the flange 12 and the lower end of the rising part 10 is provided with the second outer corner 24.
It has a sharper appearance than that of a type of ceiling panel in which a steel plate is bent to form an outer corner. In particular, when a thick plate having a plate thickness of about 3 to 4 mm is used as the plate material 8, it is difficult to form the second outer corners 24 sharply, and therefore, there is a high benefit of making the first outer corners 16 sharp. In addition, since it is sufficient for the flange portion 12 to receive the first outer corner portion 16, the width W of the frame member 4 when viewed from the lower surface is small.

Between the rising portion 10 and the plate member 8, there is provided a retaining means 26 for preventing the plate member 8 from falling downward with respect to the rising portion 10. This retaining means 2
6 is formed by forming a through hole in the retaining piece 8a and the rising portion 10 extending further upward from the bent side of the plate material 8 and driving a rivet 28 into the through hole. As shown by reference numeral R in FIG. 1, two retaining means 26 are provided for each side of the panel frame 6, and as shown by reference numeral S in FIG. There are three locations.

The ceiling panel 2 having the above configuration is supported by a V-spring 30 so as to be vertically movable, as shown in FIGS. The V-spring 30 has a winding portion 30a at the center and bent portions 30b, 30 for retaining at both ends.
It has a substantially V shape with b. Further, a bolt 32 is slidably and non-rotatably fitted into a groove 10 a integrally formed above the rising portion 10 of the ceiling panel 2, and washers 34, 34, a cylinder 36, and a V-spring 3 are fitted into the bolt 32.
The nut 30 is fastened by penetrating the 0 winding part 30a. The joint material 39 is supported by a hanger 40 attached to a suspension bolt 31 hanging down from a ceiling slab, and a notch 4 for locking the V spring 30 to the joint material 39 is provided.
The locking member 42 provided with 2a is fitted. And
By bending and locking both legs of the V spring 30 with respect to the notch 42a, the ceiling panel 2 is raised by the repulsive force of the V spring 30, and the upper surface of the contact flange 44 provided on the periphery is jointed. When it comes into contact with the material 39, the attachment is completed. Further, the ceiling panel 2 can be pulled down against the repulsive force of the V spring 30. The locking member 42 is provided with a positioning curved surface 45 that contacts the ceiling panel 2 and positions the panel.

Next, a method of assembling the ceiling panel 2 will be described. First, the above-mentioned plate member 8 having the edge portions bent is fitted into the assembled panel frame 6 from the lower surface side of the panel frame 6. Then, with the second outer corner 24 abutting on the first inner corner 14, the mounting spring 18 is pushed between the second inner corner 22 and the locking portion 20. At this time, as shown by the dashed line in FIG. 3, both leg portions of the mounting spring 18 are brought into contact with the second inner corner portion 22, and the bent convex side surface 1 is viewed from the side.
Pushing 8c in a position facing the rising portion 10 makes it easy to attach the spring. The engaging portion 20 is formed in a shape having a groove on the outside of the rectangle, and the mounting spring 18 is engaged with the engaging portion 2 in such a manner that the convex side surface 18c faces the rising portion 10.
By locking to 0, the projecting portion 18b of the mounting spring is locked by the groove of the locking portion 20 at a nearly vertical angle, and the mounting spring 20 is very difficult to come off. When fitting the mounting spring 18, the protrusion 18 b may be locked to the locking portion 20, and then the legs 18 a, 18 a may be locked to the second inner corner 22.

After the pushing of each mounting spring 18 is completed,
A through hole is drilled in a portion where the retaining piece 8a and the rising portion 10 overlap, and a rivet 28 is formed in the through hole.
To complete the assembly of the ceiling panel 2. In addition,
The rivet through holes formed in the retaining piece 8a and the rising portion 10 may be formed in advance before assembly. The retaining piece 8a is formed separately from the plate 8 and
May be welded.

Next, a second embodiment of the present invention will be described with reference to FIG. In this embodiment, in configuring the retaining means 26, a countersunk screw 50 is passed through a through hole provided in the retaining piece 8a and the rising portion 10, and a bolt 52 is screwed inside the rising piece. In addition, the hole formed in the rising portion 10 is conical counterbore to receive the head of the flathead screw.

Further, in this embodiment, the locking portion 56 of the leaf spring 58 is formed by providing a slope inclined inward in the rectangle as it goes upward. The mounting spring 58 is formed by bending both ends of the leaf spring to form the legs 58b, 58b, and bending the intermediate portion to the side opposite to the curved side of the legs 58b. And, as in the first embodiment, the leaf spring 5
8, the leaf spring 58 is fitted with the bent convex side 58a facing the rising piece 10 side.
