Prepare a board made by pasting felt onto a metal plate in advance,
Corrugated plates are processed using a forming machine temporarily installed at the construction site. In addition, when producing corrugated plates at a factory, in order to improve work efficiency and to create a curing space for the adhesive after the felt is bonded, it is sometimes necessary to prepare a plate made by bonding felt to a metal plate, etc. in advance. There are many. Therefore, it was necessary to use a special product with a synthetic fiber nonwoven fabric attached to the felt side to prevent wrinkles and cuts during molding. However, when a thin nonwoven fabric is used, the effect of preventing wrinkles and breaks during molding is insufficient, and when a thick nonwoven fabric is used, there is a problem in that the nonflammability is impaired. Further, it has the disadvantage that scratches and dirt on the surface during construction are easily noticeable, and the cost of the product also increases.

等が発生し易くなる。[Problems to be Solved by the Invention] When lining a corrugated plate such as a metal plate with felt, the metal plate or the like to which the felt is pasted is bent in advance to form the shape of the corrugated plate. For example, when forming an uneven corrugated shape with corners, the felt is bent to match the uneven shape. At this time, since the felt is greatly curved at the corners, cracks, breaks, etc. are likely to occur in the felt.

裏張り材本来の役目を果たさなくなる。[0005] The occurrence of defects such as cracks and breaks can be suppressed by imparting elongation to the felt. However, if the elongation is large, the felt will also elongate in the direction perpendicular to the waveform pitch, causing wrinkles. That is, the felt is wound up into a roll and then unwound along the direction perpendicular to the pitch, and then attached to the metal plate. At this time, if the felt partially stretches in the direction perpendicular to the pitch, it will be pulled from the periphery after being stretched, resulting in wrinkles. As a result, not only does the appearance of the product deteriorate, but also parts of poor adhesion occur between the metal plate and the felt around the wrinkles. These areas with poor adhesion may peel off from the base material due to impact, friction, etc. during handling or use as roofing sheets, etc.
The lining material no longer fulfills its original role.

In order to achieve this purpose, the present invention includes a sheet made of inorganic fibers knitted into a felt shape, and a corrugated plate to which the sheet is laminated, and the elongation rate of the corrugated plate in the pitch direction of the corrugations is set at a pitch of The elongation rate is larger than the elongation rate in the perpendicular direction.

Further, as the corrugated plate, a metal plate or a synthetic resin plate having corrugated shapes such as projections and depressions is used.

に関する伸び率よりも大きくなる。[Function] An inorganic fiber sheet can be made to have anisotropy in elongation rate by adjusting the directionality of the inorganic fibers knitted into the sheet. For example, when the blending ratio of inorganic fibers arranged in the longitudinal direction is increased, the elongation rate in the longitudinal direction of the sheet becomes smaller than the elongation rate in the width direction. Furthermore, when increasing the proportion of the flexible binder resin that interconnects the inorganic fibers in the width direction and increasing the number of binding points of the inorganic fibers in the width direction, the elongation rate in the width direction of the sheet can also be increased. is larger than the elongation rate in the longitudinal direction.

波形板２０の長手方向では、屈曲されることがない。[0010] When forming a metal plate made by laminating sheets with different elongation rates in the longitudinal and width directions into a corrugated plate, the anisotropy in the elongation rate of the sheet prevents cracks, wrinkles, etc. A product free of defects is obtained. For example, Figure 1
As shown in , when forming a metal plate 10B to which a sheet 10A unwound from a roll is pasted into a corrugated plate 20, a plurality of forming rolls corresponding to the size and pitch of the peaks 21 and troughs 22 of the corrugated plate 20 are used. The metal plate 10B to which the sheet 10A is attached is bent using a forming tool 30 equipped with 31 to 35. At this time, the sheet 10A is folded in the width direction of the corrugated plate 20 according to the peaks 21 and troughs 22. On the other hand,
The corrugated plate 20 is not bent in the longitudinal direction.

ｂの引張り力Ｆがシート１０Ａに作用する。[0011] Depending on this molding form, the amount of elongation of the sheet differs in the width direction and longitudinal direction of the corrugated plate 20. In particular, in a state where the straight lines intersect as shown in the figure, the peak portion 21 and the valley portion 22
In the corrugated plate 20 in which the sheet 10A is formed, the sheet 10A greatly expands and contracts at the bending points of the peaks 21 and troughs 22. Then, at the corner 23 of the peak 21, the direction a-
A tensile force F of b acts on the sheet 10A.

止している。The sheet 10A is stretched by the tensile force F, but when the tensile force F exceeds the elongation rate of the sheet 10A, defects such as cracks and breaks occur in the sheet 10A bonded around the corners 23. Therefore, in the present invention, by increasing the elongation rate in the width direction of the sheet 10A, that is, in the pitch direction of the peaks 21 and troughs 22 of the corrugated plate 20, defects that tend to occur in the corners 23 are prevented. There is.

ることが防止される。On the other hand, the elongation rate of the sheet 10A in the longitudinal direction of the corrugated plate 20 is set to be relatively small. Therefore, the sheet 10A is bonded to the metal plate 10B without the elongation in the longitudinal direction being locally large in a part of the width direction. Therefore, the sheet 10A bonded to the corrugated plate 20 is prevented from being wrinkled due to local elongation.

０．５〜０．２程度の範囲に維持することが好ましい。The elongation rate of the sheet 10A can be normally measured using a tensile strength tester for nonwoven fabrics, etc. The elongation rate in the longitudinal direction relative to the elongation rate in the width direction is determined by the corrugated plate 2 to which the sheet 10A is bonded.
It can be changed depending on the uneven shape of 0, and cannot be uniquely determined. For example, in the case of a sheet 10A that is bonded to a corrugated plate 20 in which peaks 21 and valleys 22 are formed with corners 23 at an angle of 120 degrees,
The elongation rates in the longitudinal direction and width direction are α and β, respectively.
When α/β=0.7 or less, preferably α/β=
It is preferable to maintain it within a range of about 0.5 to 0.2.

A felt product having a thickness of 4 mm was used. This sheet 10A has an elongation rate of 61% and 16% in the width direction and longitudinal direction, respectively, as measured by a universal testing machine used for measuring the tensile strength of nonwoven fabrics, and the tensile strength is 2 kg/cm2 in the width direction and 4 kg/cm2 in the longitudinal direction.

The length of the top surface is 40 mm in the width direction.
It was bent at an angle of 5 degrees to reach the trough 22, forming a crest 21 and a trough 22 with a bottom length of 200 mm.
