Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a ceiling panel, and particularly to a ceiling panel that simplifies assembly work at a construction site.

Conventional technology In conventional building construction, ceilings are constructed by suspending channel steel sections from ceiling slabs on upper floors using hanging bolts, and placing lightweight steel frames with an M-shaped cross section called M-bars orthogonally to these section steel sections to create a lattice-like structure. A base is prepared, and a ceiling finishing material (for example, rock wool board, gypsum board, calcium silicate board, etc.) is attached to this base using screws or other methods.

Problems that the invention aims to solve It is very time-consuming to assemble the M-bar, channel-shaped steel, and other base materials mentioned above at the construction site, and then attach multiple pieces of ceiling finishing material one by one to this, especially when facing upward. The long hours of work are quite painful. Therefore, an object of the present invention is to propose a ceiling panel that solves the above-mentioned drawbacks.

Means for Solving the Problems The ceiling panel of the present invention is made by cutting a conventional ceiling surface vertically and horizontally in a grid pattern, and each of the cut ceiling finishing materials has M bars on the back side. It is assumed that a base material equivalent to channel steel is integrally provided, and at the construction site, edge materials are attached to this ceiling panel and joined vertically and horizontally, and attached to the hanging bolts hanging from the floor slab on the upper floor. This was done with the idea of being able to easily and quickly install ceiling surfaces by hooking them up.

That is, in the ceiling panel according to the present invention, a long board is bent to form a metal or plastic edge material 2 having two recesses 3 and 4 such that the respective openings are located on opposite sides. One recess 3 of the material 2 is fitted and fixed to the periphery of the ceiling finishing material 1, and an L-shaped reinforcing material 5 is inserted and fixed into the other recess 4 of the edge material 2 at the corner of the ceiling finishing material. It is characterized in that the lower end bent portion 9 of the ceiling panel reinforcing material 8 suspended from above is inserted into and engaged with the opposing recessed portion 4 of the edge material 2 excluding the corner portion.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. Fig. 1 is a rear perspective view of the ceiling panel 7, 1 is a ceiling finishing material, 2, 2... are attached to the periphery of the ceiling finishing material 1. It is a border material. As the ceiling finishing material 1, a rock wool board, a glass wool board, a gypsum board, a calcium silicate board, a fireproof board, etc. are used. Also, edge material 2, 2...
has a self-shaped cross-sectional shape, and metals or plastics made of bent plates such as aluminum or iron plates, or extruded materials are used. These edge materials 2, 2... are fixed by applying adhesive to the periphery of the ceiling finishing material 1, and then fitting and fixing them. It is installed so that there are no gaps between the parts. The edge material 2 is formed such that the fitting recess 3 of the ceiling finishing material 1 and the recess 4 above it are oriented in opposite directions.

At the corner part of the ceiling finishing material 1, a substantially L-shaped reinforcing material 5 is applied with adhesive and inserted into the recess 4 of the edge material 2. It is securely fixed by screwing in, and thereby the corner joints of each single member of the edge material 2 are strongly reinforced. By fixing the corner portions in this way, it is possible to maintain correct right angles, and it is also possible to prevent misalignment of the joints and prevention of openings at the joints.

According to this embodiment, larger panels can be easily made compared to conventional panels, but the ceiling panel 7
When the ceiling panel becomes larger or equipment such as lighting equipment, air conditioning equipment, sprinklers, etc. are installed on the ceiling panel, a suspended ceiling panel reinforcing plate 8 is attached as shown in Figure 4 as a reinforcement. This further improves rigidity. This ceiling panel reinforcing plate 8 has a bent part 9 at the lower end.
This is fitted into the recesses 4 of the edge material 2 located on opposite sides of the ceiling finishing material 1 and suspended from above.

Furthermore, if you want to make the dimensions of the ceiling panel even larger, a fifth
Arrange the ceiling finishing material reinforcing board 10 as shown in the figure,
The lower end bent portion 11 is fixed to the back surface of the ceiling finishing material 1 with adhesive, and both ends of the reinforcing plate 10 are bent to form 12, which is fixed to the side surface of the ceiling panel reinforcing plate 8 with screws or bolts. This further improves the strength. Furthermore, if a large ceiling panel cannot be obtained due to the material of the ceiling finishing material, it is also possible to connect and bond the reinforcing plate 10 under the lower bent portion 11. Therefore, even if conventional large ceiling panels had sagging in the center and could not be used as a ceiling finishing material, this drawback can be eliminated by the method of the present invention.

Effects of the invention In the ceiling panel of the present invention, the edge material is fitted and fixed in advance to the periphery of the ceiling finishing material, L-shaped reinforcing material is inserted and fixed at the corner part, and both sides of the edge material are opposite to each other. Since it is equipped with a ceiling panel reinforcing plate that is fixed in the recess of the ceiling, at the construction site, if the ceiling panel reinforcing plate is hooked to a hanging bolt suspended from the floor slab on the upper floor with a hook fitting, etc., the ceiling surface will be fixed. A section is formed. By attaching the ceiling finishing materials one after another vertically and horizontally in this way, the ceiling surface can be compared with the conventional method where the ceiling finishing materials are fixed to the base material that has been prepared in advance on the building frame. It can be constructed easily and quickly with easy assembly work. In addition, the ceiling panel reinforcing plate significantly improves the strength of the ceiling finishing material, making it possible to manufacture large ceiling panels, and making use of the reinforcing plate to easily attach various equipment to the ceiling panel.
