Description

[Technical field]

[0001] The present invention relates to a building board forming machine that easily and quickly forms rising portions on both sides of the width of a building board, which have a continuous triangular cross-sectional mountain-shaped portion along the longitudinal direction and an arc-shaped portion along the longitudinal direction and on the horizontal plane. [Background technology]

[0002] Conventionally, architectural boards having continuous triangular ribs formed thereon, which run perpendicular to the longitudinal direction of the main board and along the width direction, have been used as exterior enclosures such as roofs and walls of buildings such as large commercial facilities, factories, gymnasiums, etc. Such architectural boards are usually long, strip-shaped materials having flat main board portions several meters to several tens of meters long.

[0003] Furthermore, some of these building boards are arched with an appropriate radius of curvature along the longitudinal direction and on the top and bottom surfaces, and are used to construct roofs with gentle curves or roofs with curves near the eaves. These building boards have vertical rising parts on both sides in the width direction, and multiple building boards are arranged in parallel and seam welded to the facing rising parts of adjacent building boards to construct the roof. There are also various types of forming machines that form building boards that are arched or have partial sections along the longitudinal direction.

[0004] However, in recent years, the appearance (design) of buildings has become more and more unique and complex. Therefore, there is an increasing demand for architectural boards with ribbed ribs that run in the longitudinal direction and on the horizontal plane. In other words, there is a demand for architectural boards that can be installed on roofs, walls, and other exterior structures in a gentle arc (curve) on the horizontal plane.

[0005] [Patent Document 1] JP 2001-30016 A Summary of the Invention [Problem to be solved by the invention]

[0006] Such building boards formed in a gentle arc (curve) along a horizontal plane can be easily bent artificially in the longitudinal direction and on the horizontal plane if they are extremely long, over several tens of meters. Therefore, such building boards that are arc-shaped on a horizontal plane can be manufactured as long materials in the longitudinal direction using a building board forming machine that can form normal ripples. In recent years, there has been a demand for building boards that are arc-shaped along a horizontal plane and have rising parts on both sides in the width direction and along the longitudinal direction for roofs, walls, etc., not only for large-scale buildings but also for the exterior enclosures of medium-scale buildings and smaller, such as roofs and walls.

[0007] However, in a normal roll forming machine, which is used to form rising portions along the longitudinal direction on both sides of a strip-shaped raw material having a ripple-like portion formed with a series of ribs perpendicular to the longitudinal direction, it is difficult to smoothly and accurately form the rising portions due to the arc shape of the raw material in the longitudinal direction and on a horizontal plane. Therefore, the problem (technical problem or purpose) that the present invention aims to solve is to provide a building board forming machine that can smoothly and quickly form rising portions on both sides of the width direction and along the longitudinal direction of a building board that is arc-shaped along the longitudinal direction and on a horizontal plane. [Means for solving the problem]

[0008] Therefore, the inventors have conducted intensive research to solve the above problems, and as a result, have come up with the invention of claim 1, which comprises a plurality of upper and lower forming roll units which rise from a gentle incline to a vertical state on one side in the width direction, and a rise height adjustment device having a position regulating unit for regulating the position of the raw material in front of the installation position of the first forming roll unit, the rise height adjustment device being capable of changing the position along the width direction of the raw material when it is properly arranged, the raw material being formed into an arc shape along the longitudinal direction and on the horizontal plane, and the rise parts are formed by the forming roll units in order on one side and the other side of the width direction of the raw material, one by one, The rising height adjustment device is provided in two units, one of which has the position regulating portion positioned toward the outer side in the width direction, and the other of which has the position regulating portion positioned toward the inner side in the width direction.

The above problems have been solved by providing a building board forming machine having the above structure.

Effect of the Invention

[0012] In the invention of claim 1, a building board forming machine is provided with a plurality of upper and lower forming roll sets that rise from a gentle incline to a vertical shape along the feed direction of the raw material at a position on one side of the width direction (sometimes referred to as the Y direction) of the properly arranged raw material. In front of the installation position of the first forming roll set, a rise height adjustment device having a position regulation part that regulates the position of the raw material in the width direction (Y direction) is provided.

[0013] The raw material is formed in an arc shape along the longitudinal direction and on the horizontal plane. In the building board forming machine, such raw material is appropriately arranged and its position can be changed along the width direction, and the forming roll unit forms the rising portions on one side and the other side of the raw material in the width direction one by one in order. As a result, the rising portions are formed in the width direction of the raw material one by one in order, so that the rising portions can be formed with extremely high precision without applying excessive load to the raw material.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. First, a building board 9 formed by the building board forming machine according to the present invention is formed by forming a raw material P of a thin flat band-shaped metal plate with a triangular cross-sectional mountain-shaped portion continuing in a substantially zigzag shape along the longitudinal direction of the raw material P, and forming an arc shape along the longitudinal direction and on the horizontal plane of the band-shaped metal plate (see FIG. 5). The arc shape may also be called a curved shape or a crescent shape.

[0020] The raw material P is a metal strip several meters (less than about 10 meters) to several tens of meters long, and is wound in a roll before being formed into a building board 9. The building board 9 formed from the raw material P by the building board forming machine of the present invention has a series of mountain-shaped portions with triangular cross sections arranged in a roughly zigzag pattern along its length, and is formed in an arc along the length and on the horizontal plane. Fig. 4(B) shows the overall shape of the building board 9, with the length of the building board 9 being L and the amount of deflection (camber) due to the arc on the horizontal upper surface being s.

[0021] The zigzag-like mountain-shaped portions of the architectural board 9, each having a triangular cross section, are called ribs 91, and a group of such ribs is called a "ripple." When the architectural board 9 is actually used to construct an exterior structure such as a roof or wall, a substantially vertical rising portion is formed on both sides in the width direction (Y direction). A plurality of architectural boards 9 processed in this manner are arranged in parallel on a base, the rising portions 92, 92 of adjacent architectural boards 9 are abutted against each other, and the rising portions 92, 92 are fixed to each other by a fixing means such as seam welding, and an exterior structure such as a roof or wall is constructed (see FIG. 6(D)).

[0022] In addition, one of the rising portions 92 on both sides of the width direction (Y direction) of the building board 9 may be formed slightly higher than the other. The part of the rising portions 92, 92 that is formed higher than the other is folded back downward to cover the upper end of the other rising portion 92 and to prevent the upper end of the connected rising portion 92 from becoming sharp (see FIG. 6(D)).

[0023] The building board 9 formed by the building board forming machine of the present invention is finished from a raw material P. The raw material P is flat on both sides in the width direction (Y direction), and ripples are formed on the entire surface. The raw material P is formed into an arc shape along the longitudinal direction and on the horizontal plane while ripples are formed by another forming machine prior to forming by the building board forming machine of the present invention, and is provided with a camber (warp or deflection) s (see FIG. 4(A)). The raw material P is formed into an arc shape along the longitudinal direction and on the horizontal plane, and here, the building board 9 has a small diameter side and a large diameter side, and the small diameter side is called the small diameter side Ma and the large diameter side is called the large diameter side Mb (see FIG. 5).

[0024] In the raw material P, on the side of the small diameter side Ma, the height dimension Ha of the rib 91 is maximum, and the pitch dimension Ka between adjacent ribs 91 is minimum (see Figs. 5(A), (B), and (D)). On the side of the large diameter side Mb, the height dimension Hb of the rib 91 is minimum, and the pitch dimension Kb between adjacent ribs 91 is maximum. The pitch dimension of the rib 91 may be equal to the width dimension of the rib 91 in the longitudinal direction of the raw material P (see Figs. 5(B) and (C)). In this state, the raw material P on which the rib 91 is formed is formed so as to be arc-shaped in the longitudinal direction and on the horizontal plane (see Figs. 4 and 5(A)).

[0025] In the description of the building board forming machine of the present invention, there are the terms X direction and Y direction as terms indicating directions. The X direction is the direction in which the raw material P is fed into the building board forming machine of the present invention and the raw material P moves during the forming process. In addition, when the raw material P and the building board 9 are placed in the building board forming machine, the longitudinal direction of the raw material P and the building board 9 is the X direction. In this state, the X direction of the building board forming machine is the same as the X direction of the raw material P and the building board 9 (see FIG. 1).

[0026] The Y direction is the width direction of the raw material P when the raw material P is properly placed in the building board forming machine, and in this state, the Y direction of the building board forming machine is also the same as the Y direction of the raw material P. In addition, in the X direction of the building board forming machine, the side into which the raw material P is fed is the front side, and the side from which the raw material P is shaped and fed out as a building board 9 is the rear side.

[0027] The building board forming machine of the present invention serves to form rising portions 92, 92 on both sides in the width direction of raw material P, which is arc-shaped in the longitudinal direction and on the horizontal plane and has ripples formed therein, to form a building board 9. As shown in Fig. 1, the building forming machine is mainly composed of a plurality of forming roll sections A, a raw material feed bed 82, a rising height adjustment device 3, a raw material presser 5, a drive motor 7, and a machine frame 8 (see Fig. 1). Here, there is a forming and feeding direction of the raw material P in the building forming machine.

[0028] The raw material feed direction is the direction in which the raw material P moves during the process of feeding the raw material P into the building board forming machine and forming the rising portion 92, and coincides with the X direction. The side from which the raw material P starts to move by the building board forming machine is called the front side, and the side from which it is fed is called the rear side. The raw material feed direction coincides with the long dimension direction (also called the longitudinal direction) of the raw material P, and the width direction of the raw material P is called the Y direction. The X and Y directions also apply to the building board forming machine when it is assumed that the raw material P is properly installed (see FIG. 1).

[0029] Of the multiple forming roll sections A, A, ..., each forming roll section A has an upper forming roll and a lower forming roll, which are configured as an upper and lower pair. The multiple forming roll sections A, A, ... are arranged only on one side of the width direction (Y direction) of the raw material P properly arranged in the building board forming machine, so that the multiple forming roll sections A, A, ... form a group along the X direction and are arranged in a row. In other words, a plurality of multiple forming roll sections A, A, ... are provided, and the multiple forming roll sections A, A, ... are arranged in a row along the X direction only on one side of the width direction (Y direction) of the raw material feed bed 82 of the building board forming machine.

[0030] The multiple forming roll sections A, A, ... form the rising portion 92 by gradually raising it from a gentle incline to a vertical shape. The raw material P passes through the multiple forming roll sections A, and the rising portions 92 are formed one by one at the ends of the width direction (Y direction) of the raw material P. In other words, the building plate forming machine of the present invention positions either the small diameter side Ma side or the large diameter side Mb side of the raw material P in the group of forming roll sections A, A, ... to form the rising portion 92, then turns the raw material P over and sends it back into the building plate forming machine, where the other side is positioned in the forming roll sections A, A, ... to form the rising portion 92 (see FIG. 4).

[0031] For example, in a building board forming machine, a rising portion 92 is formed from the small diameter side Ma of the raw material P, and when the raw material P is completely fed out of the building board forming machine, the raw material P is turned over and this time positioned so that the large diameter side Mb is on the forming roll section A side, and fed into the building board forming machine again. In this way, rising portions 92, 92 are formed on both sides of the raw material P in the width direction (Y direction), and the formation of the building board 9 is completed.

[0032] As described above, a plurality of roll forming units A are provided along the X direction to form a group of roll forming units A, and the roll forming units A each have a different shape of forming roll. Two or more roll forming units A are provided. In the embodiment of the present invention, a configuration in which three sets of roll forming units A are provided will be described (see Figs. 1 and 2).

[0033] In the case where there are three sets of roll forming units A, they are referred to as the first roll forming unit A1, the second roll forming unit A2, and the third roll forming unit A3 in the order in which they perform roll forming on the raw material P. That is, the first roll forming unit A1, the second roll forming unit A2, and the third roll forming unit A3 are arranged in this order from the front side to the rear side in the X direction. The first roll forming unit A1, the second roll forming unit A2, and the third roll forming unit A3 are arranged in a group along the X direction. In addition, in the group of the roll forming units A, A, ... described above, the forming roll unit A located first is the first roll forming unit A1.

[0034] The first roll forming section A1, the second roll forming section A2, and the third roll forming section A3 are provided only on one side in the width direction (Y direction) of the raw material feed bed 82 (see FIG. 1(A)). In other words, the first roll forming section A1, the second roll forming section A2, and the third roll forming section A3 are provided only on one side in the width direction (Y direction) of the raw material P properly placed on the raw material feed bed 82. As a result, the building board forming machine forms a rising portion 92 only on one side of the small diameter side Ma or the large diameter side Mb in the width direction (Y direction) of the raw material P in the first pass.

[0035] The first roll forming section A1 has a first upper forming roll 11 and a first lower forming roll 21, the second roll forming section A2 has a second upper forming roll 12 and a second lower forming roll 22, and the third roll forming section A3 has a third upper forming roll 13 and a third lower forming roll 23 (see Figures 1(B) and 3).

[0036] In the first roll forming section A1, the first upper forming roll 11 and the first lower forming roll 21 are arranged in parallel in the vertical direction to form a pair (see Figs. 1(B) and 3(B)). The first upper forming roll 11 is formed in a disk shape having a flat outer peripheral side surface 11a. The first lower forming roll 21 is a roll in which a substantially conical inclined outer peripheral side surface 21b and a flat outer peripheral side surface 21a are continuously provided.

[0037] The first lower forming roll 21 is formed to have a smaller diameter than the first upper forming roll 11, specifically, the diameter of the first lower forming roll 21 is approximately half the diameter of the first upper forming roll 11. The inclined outer peripheral side surface 21b of the first lower forming roll 21 has a small, gentle inclination angle with respect to the axial direction, specifically, approximately 30 degrees or less, and further, this angle may be set appropriately depending on the situation.

[0038] The flat outer peripheral side surface 11a of the first upper molding roll 11 and the flat outer peripheral side surface 21a of the second lower molding roll 22 are in the same position in the axial direction, and the inclined outer peripheral side surface 21b is located adjacent to and outside the flat outer peripheral side surface 21a in the axial direction (see FIG. 1(B)). The first upper molding roll 11 is provided with a rotating shaft 11c, and the first lower molding roll 21 is provided with a rotating shaft 22c.

[0039] Either the first upper forming roll 11 or the first lower forming roll 21 is driven to rotate by a motor, and it is preferable that the first lower forming roll 21 is driven to rotate. The raw material P passing between the first upper forming roll 11 and the first lower forming roll 21 of the first roll forming section A1 is pressed in the vertical direction when passing between the flat outer peripheral side surface 11a of the first upper forming roll 11 and the flat outer peripheral side surface 21a of the first lower forming roll 21, and the width direction end of the raw material P is raised upward at a gentle incline with respect to the horizontal by the inclined outer peripheral side surface 21b of the first lower forming roll 21 (see FIG. 3(B)).

[0040] The second upper forming roll 12 and the second lower forming roll 22 in the second roll forming section A2 have substantially the same configuration as the first upper forming roll 11 and the first lower forming roll 21 of the first upper forming roll 11. Regarding the second upper forming roll 12 and the second lower forming roll 22, the second upper forming roll 12 and the second lower forming roll 22 are arranged in parallel in the vertical direction (see FIG. 3(C)).

[0041] The second upper forming roll 12 is formed in a disk shape having a flat outer peripheral side surface 12a. The second lower forming roll 22 is a roll in which a substantially conical inclined outer peripheral side surface 22b and a flat outer peripheral side surface 22a are continuously provided. The second lower forming roll 22 is formed to have a smaller diameter than the second upper forming roll 12, and specifically, the diameter of the second lower forming roll 22 is approximately half the diameter of the second upper forming roll 12 (see FIG. 3(C)).

[0042] The inclined outer peripheral side surface 22b of the second lower forming roll 22 has a steeper inclination angle with respect to the axial direction than the inclination angle of the inclined outer peripheral side surface 21b of the first lower forming roll 21, specifically in the range of about 60 degrees. The second upper forming roll 12 is provided with a rotating shaft 12c, and the second lower forming roll 22 is provided with a rotating shaft 22c. The other configurations are the same as those of the first upper forming roll 11 and the second lower forming roll 21. The raw material P passing between the second upper forming roll 12 and the second lower forming roll 22 of the second roll forming section A2 is formed such that the width direction end of the raw material P is raised upward at a steep incline with respect to the horizontal by the inclined outer peripheral side surface 22b of the second lower forming roll 22.

[0043] The third upper forming roll 13 and the third lower forming roll 23 in the third roll forming section A3 have substantially the same configuration as the first upper forming roll 11 and the first lower forming roll 21 in the first roll forming section A1. Regarding the third upper forming roll 13 and the third lower forming roll 23, the third upper forming roll 13 and the third lower forming roll 23 are arranged in parallel in the vertical direction (see FIG. 3(D)).

[0044] The third upper forming roll 13 is formed in a disk shape having a flat outer peripheral side surface 13a. The third lower forming roll 23 is a roll in which a substantially conical inclined outer peripheral side surface 23b and a flat outer peripheral side surface 23a are continuously provided. The third lower forming roll 23 is formed to have a smaller diameter than the third upper forming roll 13, and specifically, the diameter of the third lower forming roll 23 is approximately half the diameter of the third upper forming roll 13 (see FIG. 3(D)).

[0045] The inclined outer peripheral side surface 23b of the third lower forming roll 23 is a vertical surface (including a substantially vertical surface). In other words, the range of inclination of the inclined outer peripheral side surface 23b includes a vertical surface (substantially vertical surface). The third lower forming roll 23 is configured with two continuous disks having different diameters. The third upper forming roll 13 is provided with a rotating shaft 13c, and the third lower forming roll 23 is provided with a rotating shaft 23c.

[0046] The rest of the configuration is the same as that of the first upper forming roll 11 and the second lower forming roll 21. The raw material P passing between the third upper forming roll 13 and the third lower forming roll 23 of the third roll forming section A3 has its width direction ends raised upward at a right angle (including approximately a right angle) to the horizontal by the approximately vertical inclined outer peripheral side surface 23b of the third lower forming roll 23, and the forming of the rising portion 92 is completed in a state where the raw material P is raised at an approximately right angle.

[0047] In addition, the diameters of the flat outer peripheral sides 21a, 22a, 23a of the first lower forming roll 21, the second lower forming roll 22, and the third lower forming roll 23 may be the same (including being approximately the same).By configuring in this way, when the raw material P passes through the first roll forming section A1, the second roll forming section A2, and the third roll forming section A3, the raw material P can always be maintained in a horizontal state, resulting in a stable feed state.

[0048] Next, the rising height adjustment device 3 will be described. The rising height adjustment device 3 has the role of properly positioning the raw material P on the raw material feed bed 82 of the building board forming machine of the present invention, and feeding it accurately and properly along the X direction to the first forming roll section A, i.e., the first roll forming section A1, and of setting the height of the rising portion 92. In other words, it has the role of determining the position of one end side where the rising portion 92 is formed in the width direction (Y direction) of the raw material P, and of setting the height dimension of the rising portion 92.

[0049] The rising height adjustment device 3 is located at the front side of the first forming roll section A, i.e., the first roll forming section A1, in the raw material feed direction of the raw material P. The rising height adjustment device 3 is basically composed of a position regulating section 31 and an attachment section 32. The position regulating section 31 is formed in a vertical plate shape, and the attachment section 32 is formed in a horizontal plate shape. There are two embodiments of the rising height adjustment device 3, and the first embodiment has two rising height adjustment devices 3 (see FIG. 3(E)). The second embodiment of the rising height adjustment device 3 has only one rising height adjustment device (see FIG. 3(F)).

[0050] First, in the first embodiment of the rising height adjustment device 3, two rising height adjustment devices 3 are provided. The position of the position regulating unit 31 of one rising height adjustment device 3 is located toward the outer side in the width direction (Y direction) of the raw material feed bed 82, and the position regulating unit 31 of the other rising height adjustment device 3 is located toward the inner side in the width direction (Y direction) of the raw material feed bed 82. The outer side in the width direction (Y direction) of the raw material feed bed 82 is the side away from the width direction (Y direction) of the raw material feed bed 82. The inner side in the width direction (Y direction) of the raw material feed bed 82 is the side close to the end of the width direction (Y direction) of the raw material feed bed 82.

[0051] That is, the two rise height adjustment devices 3 are used to set the rise amount K of the rise portion 92, which will be described later, to two different levels, high and low (see FIG. 3(E)). In the two rise height adjustment devices 3, the position regulating portion 31 is in the form of a vertical plate, and the position regulating portion 31 that sets the rise amount K high is in the form of a single plate (see FIG. 3(E)(I)). In addition, the position regulating portion 31 that sets the rise amount K low is provided on the surface where the adjustment plate piece 31a abuts against the end of the raw material P in the width direction (Y direction) (see FIG. 3(E)(II)).

[0052] The thickness of the adjustment plate piece 31a is set according to the rise amount K of the rising portion 92. The adjustment plate piece 31a may be formed integrally with the position regulating portion 31. That is, the adjustment plate piece 31a may change the thickness by making the position regulating portion 31 stepped. The two rise height adjustment devices 3 set the rise amount K, which is the distance between a rise reference line J (described later) and the position regulating portion 31, to two types, high and low.

[0053] In the building board forming machine of the present invention, the position regulating unit 31 determines the position of the end edge on the side where the rising portion 92 in the width direction (Y direction) of the raw material P is to be formed and the rising amount K of the rising portion 92, with the raw material P being properly positioned on the raw material feed bed 82. The raw material P has a small diameter side Ma side and a large diameter side Mb side on both sides in the width direction (Y direction), and the rising height adjusting device 3 can adjust to either side.

[0054] The mounting portion 32 is a portion where the rise height adjustment device 3 is attached to the machine frame 8, and is fixed by fasteners such as bolts and nuts. In the first embodiment, the through hole 32a of the mounting portion 32 for fasteners such as bolts and nuts is a circular hole that is slightly larger than the diameter of the bolt, and the structure does not allow the position of each mounting portion 32 of the two rise height adjustment devices 3 relative to the machine frame 8 to be adjusted.

[0055] In the second embodiment of the rise height adjustment device 3, one rise height adjustment device is provided, and the mounting portion 32 is configured to move and be fixed along the width direction (Y direction) of the building plate forming machine (see FIG. 3(F)). In this embodiment, the through hole 32b of the mounting portion 32 for fasteners such as bolts and nuts is an elongated hole formed long along the width direction (Y direction). The mounting portion 32 is capable of adjusting the position of the position regulating portion 31 of the rise height adjustment device 3 in the width direction (Y direction) by the through hole 32b which is an elongated hole and fasteners such as bolts and nuts, and by the through hole 32b which is an elongated hole in the loosened state. As a result, the rise amount K of the rise portion 92 can be adjusted and set to a desired amount by one rise height adjustment device 3.

[0056] The rising height adjusting device 3 in either the first or second embodiment sets the height dimension, i.e., the rising amount K, of the rising portion 92 to be formed in the raw material P, and first appropriately sets the position of the position regulating unit 31 in the width direction (Y direction) of the building board forming machine. Specifically, the position of the outer peripheral edge 11t in the width direction (Y direction) of the first upper forming roll 11 of the first roll forming unit A1 becomes the bending start position of the rising portion 92 to be formed in the raw material P.

[0057] The position of the outer peripheral edge 11t in the width direction (Y direction) of the first upper forming roll 11 is the left edge of the first upper forming roll 11 in Figures 2(C), (E) and 3(B). A line extending vertically from the peripheral edge 11t of the first upper forming roll 11 is defined as the rising reference line J. The distance between the rising reference line J and the position regulating portion 31 is defined as the rising amount K. The rising amount K is the height dimension of the rising portion 92 of the building board 9 (see Figures 2(C) to (F) and 3).

[0058] The rising reference line J is fixed due to the outer peripheral edge 11t of the first upper forming roll 11, and the position regulating unit 31 is variable in the width direction (Y direction) of the building board forming machine, so that the position can be changed as appropriate. When the rising portion 92 of the raw material P is set high, the rising amount K is increased (see Figs. 2(C) and (D)). When the rising portion 92 of the raw material P is set low, the rising amount K is set small (see Figs. 2(E) and (F)D). This allows one of the rising portions 92, 92 on both sides of the building board 9 in the width direction (Y direction) to be set higher or lower than the other rising portion 92.

[0059] In some embodiments, a pressure roll 4 is provided in front of the rising height adjustment device 3. The pressure roll 4 has a position regulating portion 31 extended forward, and the pressure roll 4 is attached to the position regulating portion 31. Two pressure rolls 4 may be provided in parallel. In the forming machine of the present invention, the first roll forming portion A1, the second roll forming portion A2, and the third roll forming portion A3 are driven by a transmission means such as an electric motor 7 and a chain drive 71.

[0060] Reference numeral 5 denotes a raw material holder. The raw material holder 5 is provided on the machine frame 8, and together with the rising height adjustment device 3, serves to accurately position the raw material P on the raw material feed bed 82 and to prevent misalignment in the width direction (Y direction) during roll forming of the rising portion 92. The raw material holder 5 is composed of a tip holder 51 and an extension adjustment part 52 equipped with a screw shaft and a handle, and the tip holder 51 moves along the width direction (Y direction) of the building board forming machine by operating the extension adjustment part 52. The raw material P is supported in a guided state on both sides of the width direction (Y direction) on the raw material feed bed 82 by the position regulating part 31 of the rising height adjustment device 3 and the tip holder 51 of the raw material holder 5.

[0061] In addition to the semi-circular arc-shaped building board 9 formed from the raw material P according to the present invention, there is also a roughly S-shaped curve with two continuous arc-shaped regions, a convex and a concave, as shown in Figs. 6(A) and 6(B). When forming this S-shaped building board 9, first, a building board forming machine forms ripples up to the middle position in the longitudinal direction of the raw material P to form a convex arc-shaped region. Then, the raw material P is temporarily removed from the building board forming machine, and the building board forming machine is used again to form ripples in the region where no ripples are formed, forming a concave arc-shaped portion. Fig. 6(A) shows a roof consisting of a single arc-shaped building board 9 and an S-shaped building board 9 having two arcs, and Fig. 6(C) shows a house such as a factory, warehouse, or commercial facility using this roof.

[0062] The use of the building board forming machine in the present invention will be described. The raw material P is arc-shaped in the longitudinal direction and on the horizontal plane, and has a small diameter side Ma and a large diameter side Mb in the width direction (Y direction). In order to form the rising portion 92 in the raw material P in the building board forming machine, the rising portion 92 is formed on one side of either the small diameter side Ma or the large diameter side Mb, and then the rising portion 92 is formed on the other side.

[0063] More specifically, the raw material P is placed on the raw material feed bed 82 of the building board forming machine. At this time, either the small diameter side Ma side or the large diameter side Mb side of the raw material P is positioned on the forming roll unit A group side, and the forming roll unit A group is started to form a rising portion 92 on one side of the width direction (Y direction) of the raw material P. When the first forming of the rising portion 92 for the raw material P is completed and the raw material P is completely sent out from the building board forming machine, the raw material P is turned over on a horizontal plane. Next, the turned over raw material P is sent back to the building board forming machine, and the other side side is positioned at the forming roll units A, A, ... to form the rising portion 92, so that the rising portions 92, 92 are formed on both sides of the width direction (Y direction) of the raw material P, and the forming of the building board 9 is completed (see FIG. 4).

[0064] For example, in a building board forming machine, a rising portion 92 is formed from the small diameter side Ma of the raw material P, and when the raw material P is completely fed out of the building board forming machine, the raw material P is then turned over and arranged so that the large diameter side Mb is on the forming roll section A side, and is fed into the building board forming machine again. In this way, rising portions 92, 92 are formed on both sides of the raw material P in the width direction (Y direction), and the formation of the building board 9 is completed.
