DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building exterior material capable of easily forming a heat insulating space having high surface support strength on the back side of an exterior surface, and a building 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.

On the other hand, in order to form a space that exhibits heat insulation and soundproofing effects on the back surface of a metal plate as a building exterior material,
A metal roofing sheet material disclosed in Japanese Utility Model Publication No. 60-7157 is proposed in which a plastic film sheet having a large number of convex protrusions forming independent air chambers is integrally joined via an adhesive layer or an adhesive layer. Have been. However, since the sheet as a space forming member has a configuration in which a number of convex protrusions forming independent air chambers are arranged, when the space height is large, the volume of the member alone is inevitably increased, and transportation is inevitable. There is a problem that the cost rises. In addition, since the material is made of a thin thermoplastic film, there is a problem particularly in the durability of the protruding portion under a temperature condition that reaches a maximum of about 80 ° C. immediately below the roof panel.

[0006]

The present invention has been proposed in view of the above, and is an architectural exterior material comprising a main plate serving as an exterior surface and a space forming member integrated on the back surface of the main plate, wherein the main plate is A substantially flat flat portion in the center, a forming portion for connection formed on the left and right side edges, and the space forming member includes a middle frame member provided on the back surface of the main plate so as to be expandable, and position regulating means. From the first state in which the inner frame member is superimposed substantially flush on the back side of the main plate, a tubular support portion is assembled in the longitudinal direction by expanding and bending the inner frame member. The present invention relates to a building exterior material characterized by being capable of being converted to a second state and maintaining the second state by a position regulating means, and a building exterior structure using the same.

A holding engagement portion 223 projecting inward is provided in the middle of 21. The main plate 2 having the above configuration can be produced by appropriately molding a material generally used as an exterior material,
For example, a metal material such as a color stainless steel, a color aluminum, a titanium, a color steel plate, a copper plate, or the like is formed by processing such as roll forming and pressing.

The space forming member 3 has a middle frame member 4 and a position regulating means 5 provided on the back surface of the main plate 2 so as to be expandable, and the middle frame member 4 is substantially flush with the back surface of the main plate 2. By expanding and bending the middle frame member 4 from the first state in which it is superposed in a shape, it can be converted to a second state in which the cylindrical support portion 41 can be assembled in the longitudinal direction. 5, the second state is maintained. The architectural exterior material 1 in the embodiment shown in FIG. 1 has a main plate 2 and a base member 31 as a separate member, and connects one side end of a pair of left and right middle frame members 4 and 4 to one surface (back surface) of the base member 31. Then, the other surface (front surface) of the substrate 31 and the back surface of the main plate 2 were joined. As described above, the middle frame member 4 may be configured to be connected to the main plate 2 via the base member 31 of another member, or may be directly connected to the main plate 2.

Further, the space forming member 3 can be changed in shape as shown in FIG. 2 and is provided in a building exterior structure in the shape shown in FIG. Note that FIGS. 2 and 3
The configuration of the main plate 2 to be integrated with the base material 31 is omitted, and in particular, FIG. 3 is shown upside down to clearly show the shape of the middle frame member 4. First, before use, as shown in FIG. 2A, the first state is such that the middle frame member 4 is superimposed substantially flush on the back surface side of the base material 31. From this first state, the middle frame member 4
Is expanded and bent as shown in FIG. 2 (b). Specifically, since the middle frame member 4 is provided with a node for bending at a predetermined position, the nodes of the pair of left and right middle frame members 4 and 4 are bent in a predetermined direction to form a horizontal S-shape. When folded into a shape,
This is the second state in which the rectangular cylindrical support portions 41 are formed in the longitudinal direction, and this second state is used. In the drawing, reference numeral 51 denotes a guide piece located substantially at the center with respect to the left and right middle frame members 4 and 4. In the second state, it is tilted in the vertical direction to form a short vertical wall. Then, the space forming member 3 of the illustrated embodiment is downwardly facing as shown in FIG. 3 (downward in the drawing, but upward when used for an architectural exterior structure. The same applies hereinafter). 52
1. The position regulating member 52, which is a strip-shaped plate provided with the side fitting slits 522 and 522, is used as the position regulating means 5,
In this configuration, the second state is maintained by being mounted so as to fit orthogonally to the middle frame members 4 and 4 in the second state.

An example of the concrete production of the space forming member 3 of the illustrated embodiment will be described below. First, the base material 31 and the middle frame member 4 are both made of a wide and long material.
Reference numeral 2 denotes a strip-shaped short plate having a constant width. Guide piece 51
May be a long material or a plurality of short materials arranged at appropriate intervals. The middle frame member 4 is provided with five nodes parallel to the longitudinal direction in the width direction and a first node near one end to form a fixed portion to the base material 31,
The other four nodes are provided at equal intervals so as to divide the remaining portion into five. Further, a first slit 42 orthogonal to the third node portion and a second slit 43 orthogonal to the other end are provided. In the illustrated embodiment, the middle frame member 4 disposed on the left side (on the drawing) is disposed such that the first node is located on the left side in the first state, and the fixed portion of the base member 31 (on the drawing) Joined to the upper surface. At the time of conversion from the first state to the second state, in order from the first node, vertically upward (on the drawing),
It may be folded horizontally, vertically downward (in the drawing), horizontally, vertically upward (in the drawing). Then, the first vertical surface 411 rising upward (in the drawing) from the fixed portion, the horizontal surface 412 extending horizontally from the first vertical surface 411, and the horizontal surface 412 (in the drawing)
A cylindrical support portion 41 is formed in the longitudinal direction by the second vertical surface 413 that folds downward and the base material 31, and a vertical wall located at the center is formed. The middle frame member 4 arranged on the right side in the illustrated embodiment may be configured to be left and right reversed from the above and bent. Although the left and right middle frame members 4 and 4 of the illustrated embodiment form a superimposed central vertical wall via the guide piece 51, the guide piece 51 is not necessarily provided.

[0012] The material constituting each of the above members is paper,
A resin, a resin-impregnated fiber, or the like can be used. Typically, a material that has strength and can be bent (a small number of repetitions), such as corrugated cardboard such as corrugated paper or plastic corrugated cardboard, can be used. . When the middle frame member 4 and the guide piece 51 are made of a corrugated cardboard material, the nodes for bending are formed by press working or the like. On the other hand, the substrate 3 of the illustrated embodiment
Since the first and position regulating members 52 are flat without any bent portions, the same material as the above-described middle frame member 4 may be used, or a metal plate or the like having rigidity higher than the above-mentioned materials may be used. .

When each member is made of corrugated cardboard, a process such as waterproofing, flame retarding, and hardening may be appropriately performed according to the use environment. Normal corrugated paper 4a
FIG. 4A shows a configuration in which a corrugated core flap 45 is sandwiched between opposing skin materials 44, 44 as shown in FIG. Therefore, when a corrugated paperboard 4a is prepared by laminating a synthetic resin film or using a paperboard coated with a synthetic resin solution as the skin material 44 or the core flap 45, and using this corrugated paperboard as each member, extremely waterproof properties are obtained. , It is rich in water resistance. Also,
A rust inhibitor consisting of an alkali salt of an organic acid such as amines or ethanolamine acid, a sulfur compound such as thiourea, etc.
About 0 g / m ^{2 is} applied or impregnated, and polyolefin-based or polypropylene-based film or aluminum,
A paperboard laminated with steel-based metal foil is used as a skin material 44.
When the corrugated paper 4a prepared as the core flap 45 is used as each member, the physical strength is remarkably increased, the chemical characteristics such as rust prevention and water resistance are improved, and it is possible to withstand long-term use. Further, in the corrugated paperboard 4a, when the waveform of the core flap 45 is used so as to be in the vertical direction, the strength in the vertical direction is improved, and a high support strength can be obtained. Further, as shown in FIGS. 4B to 4D, the strength is further improved when two or three corrugated paperboards 4a are superimposed and used, and particularly as shown in FIGS. 4C and 4D. In this way, when the corrugated paper flap 45 of the other corrugated paperboard 4a is used by superimposing it in the horizontal direction, the strength in the vertical direction as well as in the horizontal direction is improved, and bending at portions other than the predetermined joints is prevented. Can be prevented.

The connection between the main plate 2 and the middle frame member 4 is not particularly limited. However, in order to prevent intrusion of rainwater or the like from the exterior surface, an adhesive 12a as shown in FIG. 5B, or may be fixed with a rivet 12b using a suitable waterproofing means such as packing as shown in FIG. 5B. The same applies to the connection between the main plate 2 and the base material 31 and the connection between the main plate 2 and the guide piece 51. On the other hand, the connection between the base material 31 and the middle frame member 4 or the base material 31
The connection between the guide piece 51 and the guide piece 51 does not require the above-described waterproofing treatment. Therefore, in addition to the above-described connection means, a connection means such as a stapler, a rivet (not using the waterproofing means), a special fastener, etc. Can be joined.

The building exterior material 1 of the present invention having such a configuration is in the first state shown in FIG. 2A in which the middle frame member 4 is superimposed substantially flush before use. A large number of building exterior materials 1 can be stacked and transported in a package that is extremely easy to transport, and transport costs can be minimized.
At the time of use, the middle frame member 4 is expanded and bent as described above, so that the cylindrical support portion 41 is assembled in the longitudinal direction to the second state of FIG. Since the second state is maintained by fitting the second member 52 to the middle frame member 4, the heat insulating space 11 can be formed, and the load applied to the flat portion 21 of the main plate 2 can be supported.
In particular, when the middle frame member 4 is made of a corrugated cardboard material and the waveform of the middle core flap 45 is used in the vertical direction, high supporting strength can be obtained with a lightweight member, and the cost can be reduced. Further, in this embodiment, since the middle frame member 4 is made of two bendable plate-like materials, the manufacture of the member is easy, and the large heat insulating space 11 is formed depending on the shape of the supporting portion 41 to be assembled. It can also be done. Furthermore, since the inside of the support portion 41 is continuous in the longitudinal direction, the heat insulating space 11 formed by the building exterior material 1 becomes a circulating air layer that is continuous in the building eaves direction, and can prevent internal dew condensation. .

FIG. 6C shows another embodiment of the building exterior material 1 in which the space forming member 3 is configured such that one end of the middle frame member 4 is directly connected to the back surface of the main plate 2. The position restricting member 53 having the same length as the horizontal width of the flat portion 21 without the base member 3 and the guide piece 51 in the example is provided.
The configuration is almost the same as that of the above embodiment except that the first state is used, and the state can be converted from the first state shown in FIG. 6B to the second state shown in FIG. As shown in FIG. 6 (a), the position regulating member 53 has a semicircular center (air) passage portion 534 in the center and the side, and a small circular side (air) passage portion 53.
5 are provided, and a total of 4 side fitting slits 532 are provided.
Book is provided. Accordingly, the first slit 42 of the middle frame member 4 is orthogonal to the second and third nodes. Since the first slit 42 is U-shaped in the second state, the vertical portion (the first vertical surface 411, the second vertical surface 413) and the side fitting slit 532 are fitted, and the second slit is formed. The position restricting member 53 is attached in a state where the 43 (the central vertical wall) and the lower edge of the central passage portion 534 are fitted. The inside of the support portion 41 and the left and right empty portions of the central vertical wall are provided with a center (air) passage portion 534 and a side (air) passage portion 5.
Since the heat insulating space 11 formed by the architectural exterior material 1 does not become clogged halfway by 35, the heat insulating space 11 also becomes a circulating air layer continuous in the longitudinal direction, and can prevent internal dew condensation. In the building exterior material 1, since the position regulating member 53 is fitted to all of the five vertical wall surfaces of the middle frame members 4 and 4 to prevent the inclination thereof, the comparison is made over the entire flat surface 21 of the main plate 2. It has a uniform and high support strength to receive the load.

In order to construct a building exterior structure which is a vertically-roofed roof shown in FIGS. 7 and 8 using the building exterior material 1, firstly, a base surface 60 composed of an RC frame or a base plate or the like is appropriately placed on a ground surface 60.
