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 ceiling structure applied to a ceiling structure having a ventilation slit and a radiant cooling / heating function in a building such as a house or a general heat insulating ceiling structure.

[0002]

2. Description of the Related Art Conventionally, various studies have been conducted on ceiling radiant cooling and heating equipment for comfortable cooling and heating. In the ceiling radiant cooling and heating, a ceiling plate is a radiator plate made of a high heat conductive material such as an aluminum plate, and cooling and heating is performed by the radiant heat. Heating and cooling of the radiator plate are performed by, for example, flowing cold and hot water through a pipe attached to the back surface of the radiator plate. The applicant has developed a ventilation slit provided between the ceiling panels juxtaposed on the ceiling surface in order to promote ventilation in the room in combination with such a ceiling radiant cooling and heating facility. In this case, the central side of the ceiling surface is a ceiling radiating panel and the side edge side is a normal ceiling panel through the ventilation slit. Also in this normal ceiling panel, it is preferable that the ceiling for performing the radiative cooling and heating as described above has a heat insulating function.
Therefore, various prototypes of ceiling panels provided with a heat insulating material such as glass wool were manufactured.

However, if a metal frame is provided on the outer periphery of the ceiling panel, the weight of the ceiling panel becomes heavy and the workability is poor. It is not preferable in terms of fire resistance to use a resin frame instead of the metal frame. Therefore, an attempt was made to simply use a plate-like heat insulating material such as glass wool with a cloth attached to the lower surface, but the shape of the fore edge of the panel was not linear, and the appearance was poor. In particular, in the part along the ventilation slit, the unevenness is conspicuous unless the shape of the panel edge part is linear.

The present invention solves the above-mentioned problems, and the panel edge can be finished linearly,
Moreover, it is an object of the present invention to provide a ceiling panel and a ceiling structure capable of achieving heat insulation and weight reduction.

[0005]

A ceiling panel according to the present invention comprises a plate-like base material made of glass wool, which is formed on a lower side edge of the base material.
A flange-shaped fore part is integrally provided, and the fore part is impregnated with a resin for strengthening rigidity, and a sheet-like finishing material that covers the lower surface of the base material and is wound up to the upper surface of the fore part is provided. is there. A reinforcing frame may be partially provided on the upper surface of the base material. In this case, it is preferable that the reinforcing frame is made of light iron, and is fixed to the base material by a fastener that is inserted into an end surface portion of the base material above the small edge portion. As described above, since the sheet-like finishing material is attached to the base material made of glass wool, it is lightweight and has excellent heat insulation and nonflammability. Further, since the forehead portion is impregnated with resin to enhance the rigidity, the edge of the forehead portion and its rectangular cross-sectional shape can be maintained in a linear and orderly shape. When the reinforcing frame is provided, the reinforcing effect and the attachment to the building frame can be improved, but the partial reinforcing frame as described above can alleviate the increase in weight. When the reinforcing frame is made of light iron, it can be lightweight and have sufficient strength, and also maintain nonflammability. As described above, by using the fasteners inserted into the end surface of the base material made of glass wool, the reinforcing frame can be easily connected to the base material.

The ceiling structure of the present invention is a ceiling structure in which a plurality of ceiling panels are arranged side by side, and a slit for ventilation is provided between adjacent ceiling panels, and the ceiling is arranged on one side or both sides of this slit. The panel is a ceiling panel in which the fore edge portion having the above-mentioned configuration is reinforced. In this ceiling structure, a ceiling panel that is arranged in parallel with the above-mentioned ceiling panel for strengthening the edge through a slit may be a ceiling radiant panel having a radiant cooling / heating function. in this way,
When combined with the ceiling radiating panel, the heat insulating property of the ceiling panel of the present invention is effectively exhibited. In addition, in this ceiling structure, a non-combustible ceiling base board may be stretched above the ceiling panel. When the double ceiling is used as described above, the non-combustibility can be secured by the ceiling base board, so that the selection range of the finishing material to be attached to the ceiling panel is expanded. For example,
It is also possible to use a non-woven fabric or the like as a finishing material. When pasting the finishing material so as to be wound around the fore edge portion, incombustible materials such as glass cloth, it is difficult to attach due to problems such as glass fiber breaking, but if noncombustibility is unnecessary,
You can freely select finishing materials that are excellent in sticking work and makeup. Moreover, the use of a double ceiling can prevent heat from escaping to the outside through the back of the ceiling, and can enhance the effect of ceiling radiant cooling and heating.
