DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling panel mounting structure, and more particularly to a joint structure formed of panel materials arranged side by side, which makes it easy to mount and remove the panel materials. The present invention relates to a ceiling panel mounting structure.

[0002]

2. Description of the Related Art As an example of a conventional ceiling panel mounting structure of this type, a structure as shown in FIGS. 7 to 11 has been generally implemented. The mounting structure of a ceiling panel shown in FIG. 7 is such that joints 2 are formed by arranging panel materials 1 such as metal plates in parallel at right and left with a predetermined interval, and each of these panel materials 1 is preliminarily attached to the panel material 1. Is mounted and fixed to a mounting base 5 provided on the ceiling of a building via a second panel frame member 3, joint bottom plate 3a, and screws 4 attached to the base.

The mounting structure of the ceiling panel shown in FIG. 8 has the same basic structure as the mounting structure shown in FIG. 7, and is a part of the mounting structure shown in FIG. That is, the joint between the left and right O-shaped panel frame members 3 exposed at the bottom of the joint portion 2 and the screw 4 are covered with the cover 8 respectively. The cover 8 is detachably fixed to a cover receiver 6 fixed to the mounting base 5 via screws 7.

In the panel mounting structure shown in FIG. 9, the left and right panel members 1 are fixedly mounted on a mounting substrate 5a via a U-shaped panel frame member 3a and bolts 9, respectively, and are provided in the mounting substrate 5a. The joint bottom plate 10 is sandwiched between the square pipe-shaped mounting base 5b and the U-shaped panel frame members 3a on both sides so that the screws 4 and the like are not exposed at the bottom of the joint portion 2.

[0005] In the panel mounting structure shown in FIG. 10, the panel materials 1 on both sides are fixed to mounting bases 5 with screws 4, respectively, by using a modified O-shaped panel frame material 3 b having a step a in the middle. Utilizing the step a of the deformed O-shaped panel frame material 3b, both ends of the joint base plate 10 are placed on the step a on both sides, and the joint base plate 10
The joint bottom plate 10 is fixed with a cushion material 11 interposed between the screw and the head of the screw 4.

The panel mounting structure shown in FIG.
An arm 12 having a hook b is provided on both sides of the mounting base 5c, and a panel frame member 3c having a hook c at the upper end capable of engaging with the hook b is fitted and locked between the mounting base 5c and the arm 12. In addition, the structure is such that the panel member 1 is attached to the panel frame member 3c.

[0007]

However, the above-described ceiling panel mounting structure shown in FIG. 7 has two steps of mounting the panel frame member 3 to the mounting base 5 after mounting the joint bottom plate 3a to the mounting base 5. Since the work is required, there is a problem that the work is complicated. Further, since the screws 4 used when attaching the panel frame member 3 to the attachment base 5 are exposed and visible on the inner surface of the joint portion 2, there is a problem that the appearance is extremely poor and the appearance is impaired.

Further, the mounting structure shown in FIG. 8 requires the cover 8 and the cover receiver 6 separately, so that there is a problem that the structure is complicated and the cost is increased. Further, each time the panel material 1 or the like is removed, it is necessary to separate the cover 8 from the cover receiver 6 and the cover 8 or the like may be deformed at the time of separation.

The ceiling panel mounting structure shown in FIG.
Although it is possible to form a good-looking joint, it is difficult to perform the installation from the indoor side, and the installer must enter the ceiling and perform the installation. There was a problem that a space had to be provided above the ceiling and an installation scaffold was required. Moreover, when constructing a plurality of panel materials 1, it is necessary to follow a certain order for attachment or detachment, and there is a problem that it is impossible to construct a panel material 1 at an arbitrary place. .

The mounting structure of the ceiling panel shown in FIG. 10 has a problem that the panel frame member 3b having a very special structure must be used. In addition, the cushion material 11 and the joint bottom plate 10 must be sequentially inserted and attached to a specific space formed by a pair of panel frame members 3b provided on the back side of the narrow joint portion 2, which is extremely difficult. There was a problem.

Further, both ends of the joint bottom plate 10 have to be placed on the step portions a of the panel frame member 3b, and there is a problem that the joint bottom plate 10 is difficult to be attached and detached. In the ceiling panel mounting structure shown in FIG. 11, the special arm 12 having the hook b must be provided on both sides of the mounting base 5c.
In addition, it is necessary to accurately assemble and assemble the panel frame member 3c having the hook c at the tip, so that the structure is complicated as a whole and the panel member 1 is difficult to remove. Furthermore, since the panel member 1 is attached by engaging the hook c of the panel frame member 3c with the hook b of the arm 12, there is a possibility that the panel member 1 may fall off due to vibration such as an earthquake.

The panel mounting structure according to the present invention is a completely new technique developed in view of the above-mentioned conventional problems, and can form an extremely well-shaped joint portion, and can install the panel on the ceiling. It offers a completely new technology that allows easy attachment and detachment of materials.

[0013]

The panel mounting structure according to the present invention is a technique which fundamentally improves on the above-mentioned conventional problems, and the gist of the invention is that a plurality of panel members are connected to a panel frame member. In the ceiling panel mounting structure in which the joints are attached to the ceiling in parallel with both sides of the joint by using the mounting base and the innermost part of the joint is closed by the joint bottom plate, On the back side, the side edges of each panel frame material are erected along the joint portion, and the joint portion is closed by abutting the joint bottom plate on the side edges of the panel frame materials on both sides, and further, the joint bottom plate is connected to one side thereof. A ceiling panel mounting structure characterized by being movably mounted on a panel frame material via an elastic body inserted into a hole provided in a portion of the ceiling panel.

According to the present invention, the side edges of the panel frame material are erected along the joint portion on the back side of the panel materials arranged side by side through the joint portion as described above, and the panel frame material is placed on the side edge of the panel frame material. Since the joint bottom plate is disposed so as to be in contact with the joint plate, the innermost portion of the joint portion can be closed by the joint bottom plate.

Since the joint bottom plate is movably attached to the panel frame material via an elastic body, a construction is required in which the joint base is attached to or removed from the ceiling via screws or the like using the joint portion. In this method, the joint bottom plate is temporarily moved via an elastic body to easily open the innermost portion of the joint portion entirely and easily, and can be easily restored to the original state after construction.

Further, since the joint bottom plate is attached to the panel frame material through the elastic body inserted and engaged with the hole provided on one side thereof as described above, it can be used for many years. The joint base plate does not drop or move due to vibration or vibrations such as earthquakes.
