[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof panel for a wooden house or the like, and more particularly to a heat-insulated roof panel having excellent airtightness.

[0002]

[Technical background of the invention] In recent years, in wooden buildings, etc.,
In order to effectively maintain the cooling and heating effect in the living space, not only the wall structure but also the roof structure often use a heat insulating material made of a foamed resin or the like. In this case,
The heat insulating material is interposed between the rafters on the lower surface of the baseboard, thereby increasing the heat insulating property and airtightness of the roof structure.

On the other hand, from the viewpoint of simplifying the construction of a wooden building, a roof panel integrating a rafter, a heat insulating material, a field board, a waterproof layer and the like has been developed and put into practical use. This roof panel has only to be installed in the main building because the heat insulating material etc. are integrated, and as in the past, rafters are arranged in the main building and the like, the field board is attached, and the heat insulating material is interposed Work is no longer required, greatly simplifying construction work.

[0004] Such roof panels include, for example, purlins,
Two rafters placed on an eaves girder, a plate-like heat insulating material formed of a synthetic resin disposed between the rafters, and a rafter on the upper side of the heat insulating material so as to face the same. It consists of a field board fixed to The roof panel, for example, is disposed on the main building, and if the rafters are nailed to the main building and fixed to the frame of the timber building, the heat insulating roof structure can be configured, so that the workability of the construction can be significantly simplified. .

[0005] However, in recent years, in the wooden house, despite the fact that the wall structure and the roof structure are highly airtight and highly insulated, the above-mentioned roof panel has a heat insulating material made of synthetic resin and a wooden material. Because rafters can not always be in close contact, for example, vibration during transportation, impact during construction, vibration due to traffic of vehicles after construction, or earthquake, etc., careless force is applied to the roof panel, As a result, a gap is formed between the heat insulating material and the rafters, and there is a possibility that the airtightness and heat insulation of the room may be reduced. In addition, if the rafters are not sufficiently dried, the rafters may become thin, warped, bent, etc. due to changes in humidity or temperature.
There may be gaps between the insulation and the rafters. Furthermore, since there is a difference between the expansion ratio of the synthetic resin heat insulating material and the wooden rafter, a gap may be generated between the heat insulating material and the rafter due to a change in temperature. Then, from the gap between the heat insulating material and the rafters, there has been a problem that cool air or warm air in the living space flows out to the outside, and a cooling and heating effect cannot be effectively maintained.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above situation, and has an airtight member between a rafter and a heat insulating material for keeping the airtight between them. Accordingly, an object of the present invention is to provide a roof panel that can further improve the airtightness and heat insulation of the roof panel, make the living space airtight for a long period of time, and effectively maintain the cooling and heating effect.

[0007]
