Abstract

PROBLEM TO BE SOLVED: To develop a ceiling board with excellent heat insulating property. SOLUTION: This ceiling board is formed in flat cylindrical shape, and the interior is formed as a tubular cavity part extending along a lengthwise direction. The cavity part is filled with air, and since air is a heat insulating material of good quality, heat transfer between the surface and back face of the ceiling board is suppressed. The ceiling board itself therefore has heat insulating performance. The ceiling board of such shape can be easily manufactured at a low cost by extrusion-molding plastic.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling plate constituting a ceiling of a building.

[0002]

2. Description of the Related Art FIG. 6 is a cross-sectional view in the width direction of a state in which a conventional ceiling panel 40 is constructed. There are various types of ceiling plates, and FIG. 6 shows a long plate-like ceiling plate 40. Such a long and slender ceiling panel is often used as a ceiling panel for a living room, a bathroom, an entrance, and the like because of its quick construction and good appearance. The ceiling plate 40 has mounting portions 41 at both ends in the width direction,
42 is fixed to the ceiling base 15 by screws 16.

[0003]

The conventional ceiling plate 40
Since it was merely a plate of plastic or metal, it had little heat insulation, the efficiency of the air conditioning equipment was low, and the cost of utilities was high. In addition, when used in a bathroom, there is a problem that dew condensation easily occurs and mold is easily generated. In order to impart heat insulation to such a conventional ceiling panel, asbestos must be sprayed on the back surface of the ceiling panel 40 or a foamed plastic must be adhered to the ceiling panel 40, which requires labor and cost. An object of the present invention is to develop a ceiling plate which itself has excellent heat insulating properties without performing such treatment on the back surface.

[0004]

According to the present invention, there is provided a ceiling plate characterized by being formed in a flat cylindrical shape and having a tubular cavity along the length thereof.

[0005] The ceiling plate of the present invention is formed in a flat cylindrical shape, and the inside is a tubular cavity along the length direction. The cavity is filled with air, and since the air is a high-quality heat insulating material, heat is less likely to be transmitted between the surface and the back surface of the ceiling plate. Therefore, the ceiling plate itself of the present invention has heat insulation performance. A ceiling plate having such a shape can be easily and inexpensively manufactured by extrusion molding of plastic.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings showing embodiments. FIG. 1 shows a ceiling panel 1 of the embodiment.
FIG. 2 is a partial bottom view of the ceiling panel 1, FIG. 3 is an explanatory view of a construction state of the ceiling panel 1, and FIG. 4 is a ceiling panel 2 of the embodiment.
0 is a cross-sectional view in the width direction, and FIG.

A ceiling plate 1 shown in FIGS. 1 to 3 is formed in a substantially flat cylindrical shape by a front plate 2, a back plate 3, and side plates 4, 5, and the interior is formed by two partition plates 6 along the length direction. Classified,
Three tubular cavities 7 are formed between the front plate 2 and the back plate 3 along the length direction. In FIG. 1, a mounting plate 8 is formed so as to protrude above one side (left side) of the ceiling plate 1. The groove 9 of the mounting plate 8 is provided so that a screw for mounting on a ceiling base can easily penetrate. Mounting plate 8
A holding unit 10 is provided below the head. On the other side (right side) of the ceiling plate 1, a raised portion 11 is formed so as to protrude, and as shown in FIG. 3, the raised portion 11 rides on a holding portion 10 of the ceiling plate on the right side to support the right side of the ceiling plate 1. . As shown in the figure, the left side of the ceiling plate 1 is supported by screws 16 on a ceiling base 15.

The ceiling plate 1 has a cavity 7 between the front plate 2 and the back plate 3.
Having. The cavity 7 is filled with air, and the air is a high-quality heat insulating material. Therefore, heat is hardly transmitted between the surface of the front plate 2 and the rear surface of the back plate 3, and the ceiling plate 1 itself has heat insulating performance. It has what has. Although the partition plate 6 is not always necessary, the provision of the partition plate divides the cavity and restricts the convection of the air inside, so that not only the heat insulation performance is improved but also the strength of the ceiling plate is improved.

As shown in FIG. 3, the head of the screw 16 is not exposed at the joint 12 formed by installing the ceiling plate 1, which is excellent in design. This is because the joint bottom is formed by the riding portion 11 and hides the screw head.

The ceiling plate 1 can be manufactured easily and inexpensively by extrusion molding of plastic. By applying baking paint of various colors or metal plating, the design value can be enhanced.

The ceiling plate 20 shown in FIGS. 4 and 5 is formed into a substantially flat cylindrical shape by a front plate 21, a back plate 22, and side plates 23 and 24, and the inside is divided by two partition plates 25 and 26, and Three tubular cavities 27 are formed between the plate 21 and the back plate 22 along the length direction. In FIG. 4, a mounting plate 28 is formed to protrude above one side (right side) of the ceiling plate 20. The groove 29 of the mounting plate 28 is provided so that a screw for mounting on a ceiling base can easily penetrate. The holding portion 31 is provided at the tip of the mounting plate 28, and the holding portion 30 is provided below. On the other side (left side) of the ceiling plate 20, riding portions 32 and 33 are formed to protrude,
As shown in FIG. 5, the right side of the ceiling plate 1 is supported by riding the climbing portion 32 on the holding portion 30 of the ceiling plate on the right and the riding portion 33 riding on the holding portion 31 of the ceiling plate on the right. As shown in the figure, the left side of the ceiling plate 20 is supported on the ceiling base 15 by screws 16.

Since the ceiling plate 20 also has a cavity 27 between the front plate 21 and the back plate 22, heat is hardly transmitted between the surface of the front plate 21 and the back surface of the back plate 22, and the ceiling plate 20 itself is insulated. It has performance.

Further, as shown in FIG. 5, the head of the screw 16 is not exposed at the joint 34 formed by installing the ceiling plate 20, so that the design is excellent.

[0014]

According to the ceiling panel of the present invention, since the ceiling panel itself has heat insulating properties, it is not necessary to perform heat insulating processing on the rear surface of the ceiling panel, so that the efficiency of the air conditioning equipment is improved and the utility cost can be reduced.
In addition, dew condensation hardly occurs and the generation of mold can be prevented.
