DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to
The present invention relates to a member for easily forming a heat insulating space having a high surface support strength and an architectural exterior structure using the same.

[0002]

2. Description of the Related Art Conventionally, a roof or the like described in JP-A-53-30127 is known as an exterior structure in which a heat insulating space is formed on the back surface of a building exterior material such as a metal plate in order to improve heat insulation and sound insulation. Are known. This roof has a configuration in which a plurality of tile rods are laid in a substantially parallel manner at a fixed interval, and a shingle is arranged at the laying interval to form an air layer on the back surface of the shingle.

[0003]

However, since the roof having the above structure is not supported at all except for both side edges, when a worker walks on a portion other than the tile rod portion during or after the construction, the roof is not supported. However, there is a problem in that the roof slab is deformed due to the body weight, resulting in poor appearance or partially crushing the air layer (insulated space). Similar problems are also caused by heavy snowfall in cold regions.

Therefore, in order to solve the above problem, to support the load applied to the shingle from below, and to obtain heat insulation performance,
It has been practiced to lay a urethane or styrene resin foam insulation board or a hard glass wool board in the air layer. However, the rectangular board material impedes the flow of air in the air layer. There is also a problem that the possibility of dew condensation increases, which leads to an increase in component costs.
Further, when a hard base material such as a wood chip cement board is used to increase the supporting strength, there is a problem that the original heat insulating performance is impaired. Further, an increase in the number of members per unit area inevitably leads to an increase in transport cost, and as a result, there is a problem that the overall cost also increases.

[0005]

SUMMARY OF THE INVENTION The present invention has been proposed in view of the above, and has a base material, a middle frame member provided on one surface side of the base material, and a position regulating means. The member is connected to one surface of the base material, and from the first state in which the middle frame member is superimposed substantially flush on one surface side of the base material, the middle frame member is expanded and bent to extend in the longitudinal direction. A heat insulating space forming member for a building, characterized in that it can be converted into a second state in which a cylindrical support portion can be assembled, and the second state is maintained by a position restricting means. Related to the exterior structure of the building.

This is a configuration for maintaining the second state.

One example of the concrete production of the forming member 1 of the illustrated embodiment will be described below. First, the base material 2 and the middle frame member 3 are both made of a wide and long material, but the position regulating member 42 is a strip-shaped short plate material having a constant width. The guide piece 41 may be a long material or a plurality of short materials arranged at appropriate intervals.
