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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the embodiments shown in the drawings. The forming member 1 of the present invention comprises a base material 2, a middle frame member 3 provided on one surface side of the base material 2, and a position regulating means 4.
And a member for easily forming the heat insulating space 11 having high surface support strength.

The forming member 1 of the present invention can be changed in shape as shown in FIG. 1 or FIG. First, before use, as shown in the upper half of FIG. 1A, the upper half of FIG. 2A and FIG. It is in the first state of being polymerized. Next, from the first state, the middle frame member 3 is tilted to expand in the vertical direction to be in the second state shown in the lower half of FIG. 2 (b). It is in a stable state. Therefore, when the position restricting portion 41 provided to be tiltable on the middle frame member 3 is tilted orthogonally to the middle frame member 3 and its free edge is fitted to the adjacent middle frame member 3, FIG. 1
As shown in the lower half of (a), FIG. 1 (b) and FIG. 2 (c), the second state is stably held and becomes the use state.

[0008] The base material 2, the middle frame member 3, and the position regulating portion 41.
Paper, resin, resin-impregnated fibers, etc., can be used as the material that constitutes the material. Typically, the material has strength like a corrugated cardboard such as corrugated paper, plastic corrugated cardboard, and can be bent (a small number of times). (Repeated) material can be used. The height width of the middle frame member 3 is substantially the same as or slightly lower than the height width of a mounting member such as a rafter described later. Also,
When the middle frame member 3 is made of a corrugated cardboard material, a node (a portion fixed to the base material 2) for bending is formed by press working or the like. Furthermore, the middle frame member 3 may be a thin panel material formed of a lightweight metal material represented by aluminum in a corrugated cardboard structure, and may be integrated with the base material 2 in a foldable manner using metal, woven tape or the like (FIG. 4e, 12e in the figure
Is a metal tape). In this case, there is no need to provide a node for the bending. Such a configuration is the same for the position regulating unit 41. On the other hand, since the base material 2 does not need to be bent like the middle frame member 3 and the position regulating portion 41, the same material as the middle frame member 3 and the position regulating portion 41 may be used. A rigid metal plate or the like can also be used.

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 long, the base material 2 is wide, and the middle frame member 3 is made of a narrow material. It is made of the same short material. A bendable fixed portion is provided at one end of the middle frame member 3 and one end of the position regulating portion 41,
An appropriate connecting means described later is selected, and the fixed portion is joined to the base material 2 or the middle frame member 41. Further, as a configuration in which the free edge of the position restricting portion 41 is fitted to the adjacent middle frame member 3, a projecting piece 42 is formed on the free edge of the position restricting portion 41, and the fitting provided on the middle frame member 3 is performed. The protrusion 42 was inserted into the hole 43 and fitted.

When each member is made of corrugated paper,
A treatment such as waterproofing, flame retarding, and hardening may be appropriately performed according to the use environment. Fig. 3
As shown in FIG. 7A, a corrugated core flap 33 is sandwiched between facing skin materials 32, 32. Therefore, a corrugated paperboard made by laminating a synthetic resin film or using a paperboard coated with a synthetic resin solution as the skin material 32 or the core flap 33 is prepared, and this corrugated paperboard is used as the outer frame member 2 and the middle frame member 3. When used, it becomes extremely waterproof and water-resistant. Further, one surface is coated or impregnated with about 30 g / m ^{2 of a} rust inhibitor composed of an amine, an alkali salt of an organic acid such as ethanolamine acid, a sulfur compound such as thiourea, and a polyolefin-based or polypropylene-based material is coated on the other side. When the corrugated paperboard made of the paperboard laminated with the film or the aluminum or steel-based metal foil as the skin material 32 and the core flap 33 is used as the outer frame member 2 and the middle frame member 3, the physical strength is significantly increased. It improves chemical properties such as rust prevention and water resistance, and can withstand long-term use. When the corrugated paper is used so that the waveform of the core flap 33 is in the vertical direction, the strength in the vertical direction is improved, and a high supporting strength can be obtained. Also, as shown in FIGS. 3B to 3D, two corrugated paperboards 3a are provided.
Alternatively, when three sheets are polymerized and used, the strength is further improved,
In particular, when the corrugated paper 3a is corrugated so that the corrugation of the core flap 33 becomes horizontal as shown in FIGS. 3 (c) and 3 (d), the strength in the horizontal direction as well as in the vertical direction is improved, Bending at portions other than the predetermined joints can be prevented.

The connection between the base member 2 and the middle frame member 3 is not particularly limited. However, in the case where a fixed portion is provided at one end of the middle frame member 3 as in the illustrated embodiment, the connection is made. Figure 4

2b, rivets 12c, special fasteners 12d, and the like can be appropriately selected and used. Also, the middle frame member 3
The connection may be made by using a metal tape 12e as shown in FIG. Although FIG. 4 shows the connection between the base member 2 and the middle frame member 3, the same applies to the connection between the middle frame member 3 and the position regulating portion 41. Further, the position restricting portion 41 may be formed such that a substantially U-shaped cut is formed in the middle frame member 3 and the cut is bent in the second state.
