Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an improvement of a double fold plate material mainly used for a roof.

[Conventional technology]

Conventionally, as a plate material as described above, for example, Japanese Patent Laid-Open No. 61-25
As shown in No. 4737, a heat insulating material is filled between the widthwise intermediate portions of the outer metal plate in the cross-sectional shape in which the peaks and the valleys are alternately continuous by the inclined portions, One in which both sides of the outer metal plate are brought into contact with each other, one side edge of the inner and outer metal plates is lengthened and folded back, and the other side edges of the inner and outer metal plates are sandwiched between the folded back portions. there were.

[Problems to be Solved by the Invention]

Since the conventional double fold plate material having the inner and outer metal plates has the above-mentioned structure, it is not possible to form an air layer or an air passage between the inner and outer metal plates, and the inner and outer metal plates are not formed. There is a drawback that the connecting structure in the width direction is complicated, such as one side edge portion of the plate being lengthened to form a folded-back portion, the manufacturing is troublesome, and it is difficult to connect the folding material in the longitudinal direction.

In addition, there is a prior art of a heat insulating roof disclosed in Japanese Utility Model Publication No. 60-143816, but this heat insulating roof has a heat insulating material such as glass wool in a hollow portion formed by an outer metal plate which constitutes a folded plate. It is filled and the inner and outer plates are fastened with insulation bolts.
For this reason, there is a problem that the space between the inner and outer folded plates is maintained by heat insulating bolts, and the hollow portion is non-breathable, which is not suitable for a folded plate structure in which breathability is important.

Further, the adiabatic corrugated sheet disclosed in Japanese Utility Model Laid-Open No. 60-138928 is intended to reinforce by supporting a corrugated sheet material between upper and lower two synthetic resin sheets with a plate-like rib. Since the plate material and the plate-shaped rib are integrally formed by a continuous extrusion method using a thermoplastic synthetic resin as a material, the heat insulating corrugated plates having different heights are
There was a problem in that separate mold materials had to be provided for each. Moreover, there was no hollow portion between the upper and lower corrugated sheet materials.

The present invention has been made in order to solve the above-mentioned problems, and a space holding member is provided between the inner and outer metal plates.
It is an object of the present invention to provide a double fold plate material which can form an air layer or an air flow path between outer metal plates and can be adjusted in height and is easy to manufacture and inexpensive.

[Means for Solving the Problems]

The double fold plate material of the present invention has a cross-sectional shape in which a mountain portion and a valley portion are alternately continuous by an inclined portion, and forms a space portion over substantially the entire surface of these metal plates between outer metal plates,
Double folding in which a connecting portion formed of only an outer metal plate having at least one mountain portion and an inclined portion continuing to the outside thereof is provided on one side edge portion of the plate material along the mountain portion and the valley portion. In the plate material, at least one of a mountain portion and a valley portion in the space portion is provided with a space holding member that regulates a space between the inner and outer metal plates and forms an air flow passage.

[Action]

Since the double fold plate material of the present invention has the space between the inner and outer metal plates over substantially the entire surface of these metal plates, this space can function as an air layer and an air flow passage, and the inner and outer metal plates can be used. Since the plate is separated by the space even at both ends in the longitudinal direction, among other double fold plates located below, among the double fold plates located above the outer metal plate upper end, By overlapping and supporting the lower ends of the outer metal plates, these double fold plates can be easily connected in the longitudinal direction (usually the eaves direction), and problems such as rain leaks can be avoided. Does not happen.

On the other hand, since the inner and outer metal plates are configured to interpose a spacing member in at least one of the crests and valleys of the space portion, adhesion, spot welding, etc. can be appropriately performed depending on the material and shape of the spacing member. The space holding member and the inner and outer metal plates can be fixed by the fixing means, which facilitates the molding of the inner and outer metal plates and facilitates the formation of the uniform thickness of each space. Moreover, it becomes possible to manufacture at low cost.

Further, the double fold plate material of the present invention is only an outer metal plate having at least one ridge portion and an inclined portion continuing to the outside at each side edge portion of the fold plate material along the ridges and valleys. Since it has a structure in which a connecting portion consisting of is extended, when connecting the plate material in a lateral direction (a purlin direction orthogonal to the longitudinal direction),
It is possible to easily superimpose the connecting portion formed only of the outer metal plate from above the peak portion or the inclined portion located at the side edge portion of the other adjacent double-folding plate material.

In this case, since the connecting portion has a configuration in which the side edge portion of the other double-folding plate material adjacent to the mountain portion and the sloped portion continuous with the mountain portion are covered, there is no possibility that rainwater or the like will enter from the connecting portion. .

In addition, the space between the inner and outer metal plates can be formed continuously between adjacent double fold plates, so the heat insulation and strength peculiar to the double fold plate must be sufficiently maintained at the joints. Is possible.

[Effects of the Invention] As described above, according to the double fold plate material of the present invention, the space holding member is formed between the inner and outer metal plates by substantially the entire space of the metal plates. The space can be used as an air layer or air flow passage,
Since the inner and outer metal plates are separated by the space even at both ends in the longitudinal direction, the double fold plate located above the upper ends of the inner and outer metal plates is positioned higher than the other double fold plate material located below. By supporting the lower ends of the inner and outer metal plates in an overlapping manner, these double-folded plates can be easily connected in the longitudinal direction, and problems such as rain leakage do not occur.

On the other hand, since the inner and outer metal plates are configured to interpose a spacing member in at least one of the ridges and valleys of the space, adhesion, spot welding, etc. are appropriately performed depending on the material, shape, etc. of the spacing member. Since the space holding member can be fixed to the inner and outer metal plates by the fixing means of (3), the inner and outer metal plates can be easily formed, and the space portion with uniform thickness can be easily formed. It can be manufactured at low cost.

Further, the vertical adjustment of the inner and outer metal plates can be easily performed by changing the height of the spacing member.

Further, in particular, the double fold plate material of the present invention has at least one ridge portion and an inclined portion continuing to the outside at each side edge portion of the inner and outer metal plates along the ridge portion and the valley portion. Since a structure in which a connecting part consisting of only a metal plate and a connecting part consisting of only an outer metal plate are respectively extended is provided, when connecting the double-folding plate to the side, the double-folding plate is used. It is possible to easily superimpose the connecting portion of the other adjacent double-folding plate material from above one end portion of one. At this time, since the connecting portion formed of the outer metal plate covers the side edge portion of the other double-folding plate material by the mountain portion and the inclined portion continuous with the mountain portion, rainwater or the like does not enter from the connecting portion. In addition, since the space between the inner and outer metal plates is continuously formed between the adjacent double fold plates,
The heat insulating property and strength peculiar to the double fold plate material can be sufficiently retained even at the connecting portion.

Further, in the double-folding plate material of the present invention, at least the dimension in the longitudinal direction thereof is set to a predetermined value, so that the handling, portability, construction workability, and economical efficiency are improved, and the same number By forming an outer connecting portion and an inner connecting portion by shifting the inner and outer metal plates having a mountain portion and a valley portion from each other in the width direction by one mountain portion and superposing them, a conventional double fold is formed. There are many effects that the production cost can be further reduced by using the corrugated plate material for the plate as it is.
