Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling panel and a method of mounting the same, and more specifically, to a ceiling panel installed on a ceiling finishing material arranged in parallel via hanging bolts hanging from a ceiling slab. And its mounting method.

[0002]

2. Description of the Related Art In general, there is known a ceiling structure in which ceiling finishing materials are arranged in parallel via hanging bolts suspended from a ceiling slab and a ceiling panel is installed between these ceiling finishing materials. As one of conventional methods for mounting a ceiling panel in this type of ceiling structure, there is a structure in which the ceiling panel is placed and engaged with a locking receiving portion formed at the lower end of the ceiling finishing material. In such a ceiling structure, the ceiling panel has outward facing flanges formed on two opposing sides of a rectangular panel body, and the outward facing flanges are mounted on the lock receiving portions at the lower ends of the facing ceiling finishing materials. It is attached by matching.

[0003]

However, in the conventional structure of this type, since the outward flanges provided on the ceiling panels are placed and engaged with the locking receiving portions of the ceiling finishing material, the ceiling panels are mounted on the ceiling panels. There is a problem that bending easily occurs and the appearance of the ceiling surface is impaired. As a means to solve this problem,
A method of concealing the ceiling finishing material by inserting the ceiling panel into the ceiling finishing material is conceivable.However, in this method, it is necessary to form an engaging concave-convex strip at the end of the ceiling panel on the continuous side.
There are problems that it takes time to process the ceiling panel and that it requires skill to mount the ceiling panel.

The present invention has been made in view of the above circumstances, and the ceiling panel and the mounting thereof, in which the edge portions between the adjacent ceiling panels are close to each other and the strength of the ceiling panels is enhanced so that the ceiling panels can be easily mounted. It is intended to provide a method.

[0005]

In order to achieve the above object, a first ceiling panel of the present invention is installed between ceiling finishing materials arranged in parallel via suspension bolts suspended from a ceiling slab. Assuming that the ceiling panel is a ceiling panel, the inward flange that engages with the ceiling finishing material is formed on one of the two facing sides of the rectangular ceiling panel body that forms the ceiling surface, and the other side is adjacent An outward flange that engages with the inward flange of the ceiling panel is formed.

According to a second method for mounting a ceiling panel of the present invention, in mounting the ceiling panel according to claim 1, after the inward flange of the ceiling panel is engaged with one of the facing ceiling finishing materials, After one ceiling panel is installed by engaging the outward facing flange with the other facing ceiling finishing material, and after engaging the inward facing flange of the ceiling panel adjacent to the above-mentioned 1 ceiling panel with the ceiling finishing material, It is characterized in that the facing flanges are engaged with the inward flanges of the above-mentioned ceiling panel, and the ceiling panels are sequentially installed on the same row.

In the present invention, if the ceiling panel body is formed in a rectangular shape and has an inward flange formed on one of two opposing sides and an outward flange formed on the other side, the two sides are formed. The side orthogonal to the side may be formed in a flat shape, but it is preferable to form the reinforcing inward flange on the side orthogonal to the side having the inward flange and the outward flange. Further, the ceiling panel may be formed of one metal panel, or may be a composite panel in which a heat insulating / sound absorbing material is attached to the back surface of the metal panel body. In this case, for example, a ceiling panel can be formed by a perforated metal panel body having a large number of small holes and a heat insulating / sound absorbing material such as glass wool.

[0008]

According to the ceiling panel of the present invention configured as described above, one of two opposing sides of the rectangular ceiling panel body forming the ceiling surface is inwardly engaged with the ceiling finishing material. A flange is formed, and on the other side, an outward flange that engages with an inward flange of an adjacent ceiling panel is formed. Can be installed by raising.

In mounting the ceiling panel, the inward flange of the ceiling panel is engaged with one of the opposing ceiling finishing materials, and the outward flange is engaged with the other opposing ceiling finishing material. The ceiling panel of No. 1 is installed, and the inward flange of the ceiling panel adjacent to the above-mentioned ceiling panel is engaged with the ceiling finishing material, and then the outward flange is engaged with the inward flange of the above-mentioned ceiling panel. Then, the ceiling panels can be easily attached by sequentially installing the ceiling panels on the same row.

By pressing the upper surface of b, the ceiling finishing material 7 is fixed at an arbitrary position. Therefore, the shift preventing member 55 can prevent the ceiling panel 10 from rattling in the horizontal direction (short direction) (see FIG. 2). In addition, the slip prevention member 55 is previously slidably attached to the ceiling finishing material 7,
It is also possible to engage with the positioning slit 17 of the ceiling panel 10.

Next, a method of mounting the ceiling panel of the present invention constructed as above will be described.

First, a hanging bolt 3 is hung on the ceiling slab 1 with an anchor 2 and the hanging bracket 4 is attached to the hanging bolt 3.
Install with the nut 3a. Next, after the ceiling base material 5 is hung by the hook portion 4a of the hanging metal fitting 4, the fixing metal fitting 6 is
The ceiling finishing material 7 is orthogonally connected to the lower portion of the ceiling base material 5 to form a panel mounting space 8 between the facing ceiling finishing materials 7 and 7 and a grid portion 9.

Next, after the inward flange 16 of the ceiling panel 10 is locked to one of the lower horizontal piece 7e and the locking upright piece 7d of the facing ceiling finishing material 7 in the panel mounting space 8, the other facing ceiling. The outer flange 15 is locked to the lower horizontal piece 7e and the locking upright piece 7d of the finishing material 7, and the ceiling panel 10 of 1 is installed. Hereinafter, in the same manner, three ceiling panels 10 are installed in a grid portion 9 formed by the ceiling base material 5 and the ceiling finish material 7, and the ceiling finish material 7 below the adjacent ceiling base materials 5 and 5 is installed. , 7, the equipment panel 20 is erected by the same procedure.

After the ceiling panel 10 is installed in the grid section 9 in this manner, the ceiling panel 10 and the equipment panel 20 are also installed in the adjacent grid section 9 as well. As shown, first, after the ceiling panel 10 is inserted into the panel mounting space 8 in a state where the outward flange 15 side is lifted and inclined (see FIG. 11).
(A)) Lift up the inward flange 16 side and move it to the lower horizontal piece 7e and the locking upright piece 7d of the ceiling finishing material 7 (Fig. 11 (b)), and drop the inward flange 16 to lower the horizontal direction. It is locked to the piece 7e and the locking upright piece 7d (FIG. 11).
(C)). Then, the outward flange 15 is locked to the upper side of the inward flange 16 of the ceiling panel 10 that has already been locked, and the ceiling panel 10 is installed (FIG. 11).
(D)).

When removing the mounted ceiling panel 10,
As shown in FIGS. 12 (a) to 12 (c), the ceiling panel 10 can be removed by a procedure reverse to the above-mentioned mounting procedure. At this time, when removing the middle ceiling panel 10,
The inward flange 16 and the outward flange 1 of the ceiling panel 10 to be removed are pushed up on the outward flange 15 side of the adjacent ceiling panel 10 and are in a standby state.
The ceiling panel 10 can be removed by releasing the locked state of No. 5.

The equipment panel 20 is also attached in the same manner as the ceiling panel 10. The lighting device 21 mounted on the equipment panel 20 is supported by a fixing bolt 71 and a fixing nut 72 on an equipment mounting member 70 which is erected and fixed by a mounting bracket 60 between the facing ceiling base materials 5 and 5.
