Description

[Detailed description of the invention] This invention relates to a ceiling structure that enhances indoor heating and cooling effects.

In a general-purpose ceiling structure, the insulation effect of the ceiling body or the roof is poor, and therefore the heating and cooling effect in the room is easily influenced by the outside air, reducing the heating and cooling efficiency.

This project aims to improve the general-purpose ceiling structure and sufficiently increase heating and cooling efficiency by cutting off the influence of outside air on indoor conditions.

To describe in detail the illustrated embodiment of this project, the ceiling body 1 of the building is made of decorative board, gypsum board, etc.
A heat insulating layer 2 made of glass fiber or the like is laid out on the upper surface with a space 3 provided, and a ceiling space 5 between the roof 4 and the heat insulating layer 2 laid out on the ceiling body 1 is used for ventilation provided on the side wall 6 of the building. communicates with loa,
A communication path 8 between the ventilation lower and the ceiling space 5 is isolated from the room 9.

This ventilation lower can be freely adjusted to open and close, and a ventilation fan 10 is provided so that forced automatic intake and exhaust can be performed.

In addition to the ventilation opening 7, a natural ventilation opening 11 may also be provided so that it can be opened and closed freely.

On the other hand, for the structure under the slope, the ground 13 surrounded by the cloth foundation 12 is leveled and the lower sand 14 is laid down to a thickness of about 50 mm, and a moisture prevention sheet 15 such as vinyl chloride cloth is placed on the lower sand 14. The upper sand 16 is further layered on the entire surface of the sheet 15 by approximately 50 m, rn, while the base material for the main body 18 of the upper structure 17 constructed on the cloth foundation 12 is A heat insulating layer 19 made of fiberglass or the like is placed on the lower surface of the main body 18.
An underfloor ventilation hole 20 is provided on the side of the cloth foundation 12.
is provided to communicate with the underfloor space 21, and the underfloor ventilation opening 20 can be opened and closed freely.

The present invention is constructed as described above. In the summer, the ventilation fan 10 of the ventilation lower is operated to forcibly exhaust hot air or warm air within the ceiling space 5 to lower the temperature within the ceiling space 5 as much as possible. The indoor cooling efficiency is increased by lowering the temperature conducted to the ceiling body 1.

At the same time, open the natural ventilation port 11.

In addition, in winter, when the ventilation lower and natural ventilation [11] are closed, some of the hot air conducted from the insulation layer 4 is trapped in the ceiling space 5, so it is warm and the cold air from outside does not directly enter the ceiling space. Combined with this, it is possible to increase the heating efficiency of the room without the ceiling itself becoming cold.

In this plan, a heat insulating layer is installed on the top of the ceiling body like a diagonal top, and a ventilation hole is installed on the side of the building to forcibly ventilate or block the ceiling space, so it is difficult to use in the summer. Ventilation promotes the insulation effect of the insulation layer and increases indoor cooling efficiency.

Also, in the winter, by blocking the ventilation openings, some of the hot air that travels through the insulation layer gets trapped in the ceiling space and becomes warmer, increasing the efficiency of heating the room.
