Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a face plate material used as a roof plate or exterior plate of a building.

[Prior Art] As shown in Japanese Unexamined Patent Publication No. 1819/1983, a field board is known in which a metal plate is attached to at least one of the inner and outer surfaces of plywood with a heat insulating material interposed therebetween. There is. Further, as the above-mentioned face plate, as shown in FIG. 14, a face plate in which engaging parts 3 and 4 are formed integrally with the intermediate part 2 on one side edge and the other side edge of a single metal plate by bending them, respectively. 1 is generally used, and by engaging the engaging part 3 on one side edge of this face plate 1 with the engaging part 4 on the other side edge of the adjacent face plate 1, the adjacent face plate 1 can be attached to the eaves. It is common practice to connect them in different directions and lay them horizontally to construct a roof. Furthermore, as a face plate material, as shown in FIG.
As shown in the figure, the inner and outer surfaces of the metal plate 5 or the inner
A face plate is known in which one of its outer surfaces is coated with coating materials 7 and 8 made of synthetic resin or the like. A face plate material is also known in which a synthetic resin such as styrene resin is poured into a box-shaped cross section formed by bent inner and outer metal plates 9 and 10 and foamed to form a heat insulating material layer 6 as shown in FIG. It is being

[Problems to be Solved by the Invention] However, it is not possible to form the engaging portions 3 and 4 as shown in FIG. It is difficult, and the engaging part 3,
Even if 4 is formed, the thickness of the engaging parts 3 and 4 becomes thick up to the leading ends due to the presence of the heat insulating material layer 6 up to the engaging parts of the face plate, especially the tips of these parts, making it difficult to make the engaging parts large. There are problems in that the heat insulating material layer 6 is exposed and is easily peeled off or the surface is easily scratched. When the engaging portions 3 and 4 shown in FIG. 14 are formed on the material, the thickness can be reduced, but there is a problem that the heat insulation property is not sufficient, and the face plate material shown in FIG. When the bending process is performed, the overlapping portions of both side edges of the inner and outer metal plates 9 and 10 are opened, so there was a problem that the engaging portions 3 and 4 as shown in FIG. 14 could not be formed.

The present invention solves the above-mentioned problems, allows forming engaging parts and caulking parts on both side edges by bending, and provides heat insulation and sound insulation properties.
It is an object of the present invention to provide a face plate material for buildings that can easily be obtained with different cross-sectional shapes such as engaging parts.

[Means for Solving the Problems] The building face plate material of the present invention has an intermediate portion in which a material layer made of a material different from these metal plates is interposed between the inner and outer metal plates integrally with the inner and outer metal plates. A series of both side edges of a predetermined width are provided on both sides of the inner and outer metal plates, and the width of one of the inner and outer metal plates forming the both side edges is made wider than the other metal plate. Also, the end of one metal plate is folded back toward the other metal plate, and the end of the other metal plate is held inside this folded surface, and the end of the other metal plate is folded back. A gap was provided between the two parts as a deformation allowance.

[Function] As mentioned above, the building face plate material of the present invention has the following properties:
There is a material layer interposed between the inner and outer metal plates in the middle part, so by selecting the material appropriately,
It can provide sufficient elasticity, sound insulation, etc.
In addition, the inner and outer metal plates are directly joined at both side edges, and the relative displacement of the inner and outer metal plates that may occur when bending the engagement part with the adjacent face plate or the caulking connection part is avoided. The gap between the folded part of one metal plate and the end of the other metal plate absorbs the water. Since the inner and outer metal plates do not necessarily need to be bonded, the bending process can be easily performed.
Therefore, a face plate having a desired shape can be obtained.

[Examples] Examples of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment of the invention. In Fig. 1, 11 is an outer metal plate made of corrosion-resistant material such as copper or stainless steel with a thickness of about 0.1 to 0.2 mm, and 12 is a relatively strong steel plate with a thickness of about 0.5 to 1.6 mm. The inner metal plate consisting of etc., 13 has a thickness of
The face plate material 14 is a heat insulating material layer made of a rubber or synthetic resin plate with a thickness of about 0.5 to 5 mm.

The inner metal plate 12 and the outer metal plate 11 are directly joined at both side edges 14a and 14b of the face plate material 14 in the width direction. A thermally insulating material layer 1 is provided in the intermediate portion 14c of the face plate material 14 between the side edges 14a and 14b.
3 is interposed therebetween, and this material layer 13 is fixed to the inner and outer metal plates 12 and 11 by heat fusion or adhesive bonding. Note that the inner metal plates 12 are each bent outward at the intermediate portion 14c of the face plate material 14 to ensure a gap in which the material layer 13 is interposed.

In addition, both side edges 14 of the inner and outer metal plates 12 and 11
The dimensions in the width direction at a and 14b are different from each other, for example, at the right end shown in FIG.
2 is large, and from the middle of the outer metal plate 11
The outer metal plate 11 is bent in a substantially U-shape direction to form a folded part 14d, and the end of the outer metal plate 11 is held between the ends of the folded part 14d. On the other hand,
Similarly, at the left end, the inner metal plate 12 is large in size, and is bent halfway toward the outer metal plate 11 in an inverted U shape to form a folded part 14e, and at the end of this folded part 14e, the inner metal plate 12 is large. The structure is such that the ends of the plate 12 are held in place. Furthermore, gaps 14f and 14g as deformation allowances are provided inside the folded portions 14d and 14e at both ends, respectively, between the ends of the outer metal plate 11 and the inner metal plate 12. In this case, as described above, the folded portion 14d is formed on the inner metal plate 12 at one side edge 14a, while the folded portion 14e is formed on the outer metal plate 11 at the other side edge 14b. As will be described in detail later, this face plate material 14 is premised on bending one side edge 14a outward and the other side edge 14b inward to obtain the face plate 17 as a finished product. It is. In addition, as described above, both side edges 14a of the inner and outer metal plates 12, 11,
14b is a folded portion 1 formed at each end.
4d and 14e, the inner and outer metal plates 12 and 11 are maintained in an integrated state without needing to be bonded at the respective side edges 14a and 14b. ,
This part can also be bonded together using a sticky adhesive or the like, if necessary. Further, in this embodiment, both side edges 14a of both plates 14,
The width of the intermediate portion 14b is 50 mm, and the width of the intermediate portion 14c is 300 mm.

Face plate material 14 of the embodiment configured as above
As shown in FIGS. 3 and 4, engaging portions 15 and 1 are formed on both side edges 14a and 14b by secondary bending.
6 is used as a finished product face plate 17. The engaging portion 15 on one side edge of the face plate 17 is formed in a cross-sectional shape in which an S-shaped portion 15b is continuous on the inclined folded portion 15a, and the engaging portion 16 on the other side edge is formed downward in a substantially U-shape. The lower side 16a of the bent portion is bent into an F-shape, and an upwardly folded curved portion 16b is formed at the tip. and,
This face plate 17 is arranged such that the end portion of the lower side 16a of the engaging portion 16 and the folded curved portion 16b are connected to the adjacent face plate 17.
It is used to construct a side-roofed roof in the same way as the conventional one shown in FIG.

By the way, when bending the face plate 14 as described above, as shown in FIGS. 5A to 5C, the stronger the angle of bending inward (or outward), the more the face plate 14 becomes inward with respect to the curve. The outer metal plate 11 tends to move relatively toward the tip due to the deviation between it and the inner metal plate 12 due to bending, but this movement is caused by the gap 14f being formed inside the folded portion 14d. It is absorbed by this gap 14f, and the outer metal plate 11 can escape toward the distal end while being held by the folded portion 14d. Needless to say, this point also applies when bending the other edge 14b. Therefore, the above-mentioned bending process can be easily performed, in other words, it is possible to perform strong or acute bending, so that the engaging parts 15 and 16 are not unnecessarily enlarged, and furthermore, the aforementioned bending process can be carried out easily. This will improve the appearance of the roof when it is raised. In addition, if the inner and outer metal plates 12 and 11 are firmly joined to each other at both side edge portions 14a and 14b using a highly rigid adhesive or welding, the inner and outer metal plates 12 and 11 due to the bending process will be Since the misalignment between the metal plates 12 and 11 cannot be absorbed, there is a risk that the metal plate on the inside of the bend may buckle and become deformed, especially during fine bending. Such inconveniences can be reliably avoided. In addition,
Both side edges 14a, 14 of inner and outer metal plates 12, 11
If the part b is pasted together using adhesive, the inner and outer metal plates 12 and 1 will be removed during the bending process.
Since the adhesive itself may be deformed by the shearing force generated during step 1, deformation of the metal plate side can be avoided.

The face plate material 14 of this embodiment is not limited to the one shown in FIGS. 3 and 4, but also has an appropriate cross-sectional shape by bending both side edges 14a and 14b, as shown in FIGS. 6 to 9. In this case, the width of at least one side edge of the face plate material 14 may be cut off if necessary.

10 to 13 show different embodiments of the face plate material according to the invention. The face plate material 14 shown in FIG. 10 has narrower widths at both side edge portions 14a, 14b where the inner and outer metal plates 12, 11 are directly joined, and folded portions 14d, 14e as shown in FIGS. 3 and 4. It was formed upside down. The face plate material 14 shown in FIG. 11 has both side edges 14a,
14b is made wider on one side and narrower on the other, and the face plate 17 is processed into a continuous trapezoidal wave-like cross-sectional shape called a folded plate shape as shown in Fig. 12, and the vertical roof as shown in the figure is used. Used when constructing a new or reroofing. Face plate material 1 shown in Figure 13
4 is suitable for bending both side edge portions 14a and 14b in the same direction, that is, outward in this example, and in this case, folded portions 14d and 14e are formed at both ends of the inner metal plate 12. Needless to say, it will happen. Note that the face plate material 14 of the present invention is
Folded portions 14 are provided at the tips of both side edges 14a and 14b.
d and 14e are provided, safety during construction work is higher than when these are not present, i.e., where the cut end of the metal plate is directly used as the end of the face plate. From the viewpoint of preventing injuries to workers at both ends, it is not necessarily necessary to perform spiral bending on both ends as shown in the above embodiments. In addition, in the present invention, the material layer interposed between the inner and outer metal plates may be a synthetic resin foam, a wood wool board made of wood wool fixed with cement, an appropriate fireproof material, fireproof paper, or a lead board. One of the inner and outer metal plates may be a flat plate, and the other may have a groove into which the material layer is fitted.It can also be used as a face plate for the exterior of a building. The surface may be coated with an appropriate coating to prevent peeling of the material layer.

[Effects of the Invention] As explained above, the face plate material of the present invention has the following properties:
A material layer made of a material different from that of the inner and outer metal plates, such as a heat insulating material, is interposed between the inner and outer metal plates in the width direction of the face plate,
In addition, due to the folded parts provided at the tips of both side edges,
By maintaining the direct bonding state of the outer metal plates and ensuring enough deformation allowance for the inner and outer metal plates during bending, it is possible to bend the edges on both sides when fabricating the face plate through secondary processing. Even when the inner and outer metal plates are pressed against each other, there is no possibility of undesirable deformation, and therefore, the engaging portions and the like can be easily formed. Furthermore, since the face plate made of the face plate material according to the present invention does not have a heat insulating material interposed between the inner and outer metal plates of the engaging part, the engaging part can be made smaller and the engagement of adjacent face plates can be made smaller. By appropriately selecting the material of the material layer interposed between the inner and outer metal plates of the intermediate part, sufficient heat insulation and sound insulation properties can be obtained. The effect is that mass production can be carried out in a short period of time.
