2. Description of the Related Art Conventionally, in a typical wooden house, the upper end of a pillar erected on all sides and the studs erected in the middle of the pillar has a shed bar installed in the beam direction and an eave girder installed in the girder direction. As a roof structure for connecting and framing, and supporting the roof on this framing with a predetermined slope, erection of the huts from the hut above, and the height position at the upper end of the huts is different. The purlins and haze are laid in parallel along the direction of the girder as a horizontal bridge, and a plurality of rafters are laid in parallel on the horizontal bridge at a predetermined gradient along the beam-to-beam direction. A base material called a field board is stretched on the top, and a sheet-shaped waterproof material such as asphalt roofing is stretched on the upper surface, and then roofing materials such as roof tiles are attached.

However, it has become difficult to secure skilled human resources and a wide working space, and to improve work efficiency to shorten the construction period and cost by the conventional construction method mainly for on-site construction. Therefore, in recent years, a unit construction method in which each part of the building is unitized in advance and produced in a factory, which is carried into the site and assembled is actively carried out, and in particular, paneling is particularly remarkable for walls, floors and roof structures. In the case of these roof structures, for example, a roof panel in which a foundation panel is stretched on both upper and lower sides of a timber framed in a grid pattern, and a heat insulating material such as expanded polystyrene foam is mounted between the foundation panels. There is a construction in which the above is manufactured at a factory and is carried to the site and is attached to the above-mentioned purlins and the eaves with a predetermined gradient along the beam direction.

Can not be effectively used for dehumidification or heating, etc., and warps the base panel to make the placement of the roof tile unstable or deteriorate the adhesive layer of the sheet-shaped waterproof material to deteriorate the waterproofness. There is a fear.

Secondly, if timber is previously attached to the roof panel, it is inconvenient to handle when carrying it in or assembling it, and it cannot be freely cut and used. Is unsuitable for use in roof structures with butt joints such as.

Therefore, the heat insulating roof panel according to the present invention is mainly aimed at solving the above-mentioned problems of the prior art. Particularly, the radiant heat of the heat insulating material is convected to be appropriately dissipated, and it is convenient to handle and can be cut freely. Thermal insulation roof panel and roof structure that can be used as
