In addition, the ceiling material can provide a comfortable indoor life by providing a sound absorbing material on one side to absorb various noises that may occur indoors.

In the past, plywood, chipboard, balmlight, and gypsum board were mainly used as ceiling materials. However, these ceiling materials cannot provide both structural strength and insulation properties with only one material, so most of them have glass wool, rock wool, styrofoam, etc. built into the ceiling materials. It was being used in its form. However, the law has recently been revised to require the use of non-combustible, semi-non-combustible, and flame-retardant materials for all interior finishing materials, and the use of some ceiling materials has been banned because they produce carcinogens harmful to the human body, so the use of metal ceiling materials is expanding. .

The base includes a fixing plate, a hole formed in the center of the fixing plate, and a piece that is inserted through the hole and screwed to the clip bar through the engaging hole.

However, in this conventional ceiling material system, the upper surface of the fixing plate is formed flat, and the upper surface of this fixing plate is in overall contact with the lower surface of the ceiling plate, thereby increasing the mutual contact area, which causes the contact between the fixing plate and the ceiling plate through the piece. When fastening, the area of the ceiling plate that is pressed by the fixing plate expands and the pressure is distributed, so there is a problem in that it is difficult to fasten firmly.

In addition, the conventional ceiling material system has a problem in that when vibration due to an earthquake or wind is applied, the piece fastened to the clip bar through the fixing plate and ceiling plate can be easily loosened.

In addition, the conventional ceiling material system has a problem in that pieces can easily come loose, causing safety accidents such as falling of the ceiling plate.

In addition, the conventional ceiling material system has a problem in that a lot of force is required when fastening the fixing plate and the ceiling plate through the pieces, which may reduce workability.

When the piece 700 is fastened to the clip bar 300 through the through hole 611a, the sealing guard 600 is secured by the elasticity of the bottom portion 611 and the inclined portion 613, which are the loosening prevention portion 610. As a result, tension is applied to the piece 700, thereby suppressing rotational loosening of the piece 700. This may be the same principle as a spring washer, and in particular, in this sealing guard 600, even when vibration due to an earthquake or wind is applied, the loosening prevention part 610 acts as a spring washer, so that the piece 700 is damaged by vibration. This can prevent it from coming loose easily.

Referring to FIG. 5, a hole 613a may be formed in the inclined plate. At least one hole 613a may be formed in the inclined plate. The hole 613a may be formed as a square hole. The hole 613a may be formed from the top to the bottom of the swash plate along the slope of the swash plate. The hole 613a may serve to reduce the elastic modulus of the loosening prevention portion 610. The ceiling guard 600 can fasten the piece 700 with a small force due to the hole 613a when fastening the ceiling guard 600 and the ceiling material 500 through the piece 700, which improves workability. It can be improved.

The bottom portion 611' may be formed of a plate having an equilateral triangle shape that is smaller than the flange portion 620'. An inclined portion 613' may be formed integrally with the bottom portion 611'. The inclined portion 613' may be formed to be inclined outward over the entire circumference of the bottom portion 611'. The inclined portion 613' may be interposed between the bottom portion 611' and the flange portion 620' to connect the bottom portion 611' and the flange portion 620'. The inclined portion 613' may be formed in the shape of a triangular pyramid whose cross-sectional area increases from the bottom portion 611' to the flange portion 620'. The flange portion 620' may be formed to be stepped from the bottom portion 611' by an inclined portion 613'. The inclined portion 613' may include a plurality of inclined plates. The inclined plate may be formed as a trapezoid-shaped plate. The inclined plate may be formed on each of the four sides of the bottom portion 611' and may be formed to surround the bottom portion 611'. The upper end of the inclined plate may be connected to the flange portion 620', and the lower end may be connected to the bottom portion 611'.

When the piece 700 is fastened to the clip bar 300 through the through hole 611a', the sealing guard 600' has a bottom portion 611' that is a loosening prevention portion 610' and an inclined portion 613. '), tension is applied to the piece 700 due to its elasticity, thereby suppressing rotational loosening of the piece 700. This may be the same principle as a spring washer, and in particular, this sealing guard 600' has a loosening prevention part 610' acting as a spring washer even when vibration due to an earthquake or wind is applied, so that the piece 700 is damaged by vibration. ) can be prevented from being easily released.

Referring to FIG. 10, a hole 613a' may be formed in the inclined plate. At least one hole 613a' may be formed in the inclined plate. The hole 613a' may be formed as a square hole. The hole 613a' may be formed from the top to the bottom of the swash plate along the slope of the swash plate. The hole 613a' may serve to reduce the elastic modulus of the loosening prevention portion 610'. The ceiling guard 600' can fasten the piece 700 with a small force due to the hole 613a' when fastening the ceiling material 500' with the ceiling guard 600' through the piece 700. This can improve workability.
