BACKGROUND OF THE INVENTION
The present invention relates to a roof panel constituting a roof surface of a wooden house, and more particularly to a ventilated roof panel for constructing a roof structure having a ventilation layer and a mounting structure thereof.
[0002]
[Prior art]
In order to construct the roof surface of a wooden house, a roof panel prepared by previously filling a heat insulating material in a factory or the like is used. This roof panel is attached to a climbing beam or the like of a hut structure that is a frame structure that supports the roof at the site. Such a heat insulating roof panel is described in, for example, (1) JP-A-5-340018.
[0003]
When the roof surface is formed of a roof panel filled with such a heat insulating material, a ventilated roof structure is formed in which a vent layer is formed between the panel upper surface and the base plate in order to prevent condensation and the like. Conventionally, in order to form this ventilation layer, after attaching a roof panel at the site, a rafter was attached to the roof surface by field construction, and a field board was attached thereon.
[0004]
However, the installation work of rafters and field boards in such on-site construction is troublesome and requires a long construction period.
Therefore, a roof panel in which a ventilation layer is previously formed on the upper surface of the heat insulating material between the front surface material and the back surface material of the panel has been proposed ((2) JP-A-8-277596). By attaching the roof panel having such a ventilation structure to the roof surface, it is not necessary to attach a rafter or a field board for the ventilation structure at the site, and the workability is improved.
[0005]
The heat insulating panel having a ventilation layer described in this publication covers a front surface and a back surface of a frame member with a front surface plate and a back surface plate, respectively, and forms a heat insulating material and a ventilation layer inside thereof to form a rectangular body (housing shape) heat insulation. The panel is configured. When this heat insulating panel is attached to the roof surface, a plurality of heat insulating panels are arranged side by side with their adjacent frame members facing each other.

However, in the heat insulating panel described in the above-mentioned publication (2), the peripheral side surface of the casing-like panel is planar, and when arranging a plurality of panels adjacent to each other, the side surfaces are brought into contact with each other. When fixing to a beam or the like, it must be fixed by using a fixing member such as a nail having a length longer than the thickness of the panel or by other special attachment means. Therefore, the workability of the heat insulation panel is not sufficiently improved, and problems are likely to occur in terms of airtightness.
[0007]
On the other hand, in the heat insulating panel structure described in the above (1), a frame is formed by covering both sides of a frame material filled with a heat insulating material with a rectangular plywood, and the bonding plywood is shifted in the vertical direction on both upper and lower surfaces. The heat insulating panels adjacent to each other are fitted and connected at the shifted portion. However, in the heat insulating panel structure described in this publication, since the plywood for bonding is further provided above and below the upper and lower plywood constituting the panel housing, the thickness of the entire panel is increased, and if a ventilation layer is further combined with this, As in the case of the above-mentioned publication (2), problems are likely to arise in terms of workability and airtightness in terms of attachment to a beam or the like when the thickness is increased and unitized as a heat insulation panel.
[0008]
The present invention is based on the above prior art, and has a ventilated roof panel having a compact shape and a ventilation layer and a heat insulating material integrated into a single unit to improve installation workability on the site and airtightness, and its The purpose is to provide a mounting structure.
