Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an improvement of a standard length orthograph material mainly used for roofs.

[Conventional technology]

Conventionally, as the standard length plate material as described above, for example, JP-A-61
As disclosed in Japanese Patent Publication No. 254737, a heat insulating material is filled between the widthwise intermediate portions of the inner and outer metal plates having a wavy cross section in which peaks and valleys are alternately connected by inclined portions. Both side portions of the inner and outer metal plates are brought into contact with each other, and one side edge portion of the inner and outer metal plates is lengthened and folded back, and the other side edge portions of the inner and outer metal plates are sandwiched between the folded back portions. There was something.

[Problems to be Solved by the Invention]

Since the conventional fixed-length plate material having the inner and outer metal plates has the above-described structure, it is impossible 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 problem in that it is troublesome to manufacture by making one side edge of the plate long to form a folded-back portion, and further it is difficult to connect the fixed-length plate material in the longitudinal direction.

Further, the dew condensation prevention roofing material disclosed in Japanese Patent Laid-Open No. 59-27055 is a deformable synthetic resin waterproof sheet, in which a large number of ridges are formed on the back surface of a synthetic resin corrugated sheet. It is made by laminating and integrating the elastic sheets. Moreover, the width of the ridge is
Since the height of the ridge is 0.5 to 10 mm and the height of the ridge is 0.5 to 10 mm, it is practically almost the same as a sheet made of foam attached to the back of a synthetic resin corrugated sheet. However, there is a room for improvement in terms of breathability, and there is a problem that it is not suitable for a metal folding roof.

Further, there is a prior art of a heat insulating roof disclosed in Japanese Utility Model Publication No. 60-143816, but this heat insulating roof is provided with 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 a heat insulating bolt and the hollow portion is non-breathable, which is not suitable for a folded plate structure in which breathability is important.

The present invention has been made to solve the above-mentioned various problems, and it is possible to form an air layer or an air passage between the inner and outer metal plates, and to easily connect them in the longitudinal direction. It is an object of the present invention to provide a standard length orthograph material that can be obtained easily and at low cost.

[Means for Solving the Problems]

The invention of claim 1 forms a space portion over the entire surface of these metal plates between the inner and outer metal plates of the cross-sectional shape in which the peaks and the valleys are alternately continuous by the inclined portions, and the inside of the space is formed. This is a standard length plate material in which a spacing member is fixed to both the peaks and valleys, and the inner and outer metal plates are fixed via the spacing member.

Further, the invention of claim 2 is the above-mentioned standard length plate material,
The spacing member is a plate-shaped member having a support portion in which the inner and outer metal plates have a width equal to the width of the short sides facing each other at the peaks and valleys, and inclined portions bent from both sides of the support portion. And the tip of the inclined portion is formed at an interval equal to the width of the long side where the inner and outer metal plates face each other at the peak and the valley, and the tip of the inclined portion of the spacing member is provided on both sides of the long side. The inner and outer metal plates are engaged with the bent portions of the slanted portions, and the supporting portions of the spacing members are supported on the short sides where the inner and outer metal plates face each other at the peaks and valleys.

[Work]

In the fixed-length plate material according to claim 1, since the space portion is formed between the inner and outer metal plates over the entire surface of these metal plates, the space portion can be used as an air layer or an air passage, and
Since the outer metal plate is separated by the space even at both ends in the longitudinal direction, the fixed metal plate placed above the upper end portion of the outer metal plate in the fixed-length plate material arranged below. By supporting the lower ends of the metal plates in the shaku origami plate by overlapping them,
It is possible to easily connect the standard length plate materials in the longitudinal direction without causing problems such as rain leakage.

Since the inner and outer metal plates are fixed with the spacing members at both the peaks and the troughs of the space and are fixed through the spacing members, the material and shape of the spacing members are different. Accordingly, the spacing member and the inner and outer metal plates can be fixed to each other by an appropriate means such as adhesion or spot welding. Therefore, coupled with the ease of forming the inner and outer metal plates,
It is possible to easily and inexpensively manufacture a space in which the thickness of each part is uniform.

Further, in the fixed-length plate material of claim 2, the spacing member has a support portion formed with a width equal to the width of the short sides of the inner and outer metal plates facing each other at the ridges and valleys, and the support portion. It is made of a plate-shaped material having an inclined portion formed by bending from both sides, and the tip of the inclined portion is formed with an interval equal to the width of the long sides where the inner and outer metal plates face each other at the peak and the valley, and the spacing member By locking the tip of the inclined portion of the inclined portion to the bent portion of the inclined portion of the inner and outer metal plates continuous on both sides of the long side, and supporting the support portion of the spacing member on the short side, The space holding member can be easily positioned with respect to the facing surfaces of the peaks and valleys of the inner and outer metal plates, and therefore the work of fixing the inner and outer metal plates via the space holding member becomes easier.
