  By the way, when using such a roll molding machine, for example, when molding an extremely short length (less than 1 m in length), it is difficult to transfer the plate material from the roll pair to the roll pair. Therefore, it is molded in advance using a plate material having a long length, and is then cut to a desired length through a cutting operation using a high-speed cutting machine or a plasma cutting machine with an abrasive disk. However, in such a cutting operation, a positioning step for determining the cutting site is indispensable, and there is a problem that the cutting itself takes time, and the occurrence of burrs is also unavoidable. It cannot be said that it can be manufactured. In addition, when the plate material involved in molding has a complicated cross-sectional shape, there is a concern that the cross-sectional shape may be deformed at the time of cutting, which may limit the molding of the plate material using a roll molding machine. There is still room for improvement.

A roll-molded plate-like body provided with a cross-sectional shape having a shape, the plate-like body being formed from one end to the other end in the width direction, and a fixed-plate shape by bending with the portion as a base point It is a roll-formed plate-like body characterized by having at least one planned break line that can be separated into the body.

  The planned breaking line has a thickness equivalent to that of the plate material, and is formed from at least one narrow piece that can be broken by bending of the portion, and at least one notch formed adjacent to the narrow piece. Or at least one narrow piece that has the same thickness as the plate material and can be broken by bending the portion, and is formed adjacent to the narrow piece, It is preferable to consist of at least one through-hole penetrating in the thickness direction.

  Further, the present invention provides a method for manufacturing a roll-formed plate-like body, wherein a planned fracture line is formed on a plate material paid out from a steel plate coil, and then a roll molding machine including a roll pair sandwiching the plate material is used. A method for producing a roll-formed plate-like body, characterized in that a cross-sectional shape having a shape equivalent to that of a caliber formed on the roll surface of the roll is imparted by passing the plate once or multiple times.

  Furthermore, the present invention comprises at least one pair of roll pairs for sandwiching a plate material paid out from a steel plate coil, and allows the roll surfaces of the rolls to pass through the rolls between the rolls one or more times.

Hereinafter, the present invention will be described more specifically with reference to the drawings.
FIG. 1 is an external view showing an embodiment of a roll-molded plate according to the present invention as an example of a fitting roof material (upper flat roof material) provided with an upper goby and a lower goze at the end in the width direction. FIG. 2A is a perspective view, FIG. 2A is a plan view of FIG. 1, and FIG. 2B is a front view of FIG. Specifically, the roll-formed plate-like body is a metal such as a galvanized steel sheet having a thickness of about 0.3 to 1.2 mm, an aluminum zinc alloy plated steel sheet, a stainless steel sheet, a copper sheet, an aluminum sheet, or a coated or coated steel sheet thereof. What was comprised with the manufacturing member is applied.

  The mating roofing material shown in FIGS. 1 and 2 has the same cross-sectional shape, and prepares a plurality of pieces having different lengths and planar shapes. By linking them together, the roofing materials can be joined together from the eaves of the building structure to the ridge, while the upper and lower goby are fitted to the lower and upper gores of the adjacent roofing material. Thus, the roof materials along the eaves of the building structure can be joined together, and roofing is performed by repeating these joining operations.

  Reference numeral 1 in the figure denotes a flat roofing material body, 2 a lower goby provided at one widthwise end of the roofing material body 1, and 3 a roofing material body 1 in the other width direction. It is an upper goby provided at the end. Reference numeral 4 denotes a planned fracture line formed from one end in the width direction of the roof material body 1 toward the other end. The planned fracture line 4 has the same thickness as the plate material before molding, and a narrow piece 4a that can be broken by bending the portion, and a through-hole that penetrates in the thickness direction of the roof material body 1 4b. The dimensions of the breakable narrow piece 4a are appropriately determined according to conditions such as the material and thickness of the target roofing material. For example, in the case of a galvanized steel sheet having a thickness of about 0.3 to 0.5 mm, it is about 1 to 20 mm. In addition, although the planned break line 4 shows an example of a combination of the narrow piece 4a and the through hole 4b, the narrow piece 4a and the notch 4c (see FIGS. 8 and 10) or the narrow piece 4a, the through hole 4b, and the notch 4c can be combined as appropriate. The opening gap t of the through opening 4b is also determined as appropriate according to the material and thickness of the target roofing material. For example, in the case of a galvanized steel sheet having a thickness of about 0.3 to 0.5 mm, it is about 1 to 20 mm.

  In the case of manufacturing a fitting roof material such as the above using a plurality of roll pairs, for example, using a multi-stage roll molding machine, if the object is extremely short, the plate material, Since it is difficult to transfer from roll pair to roll pair, a long length is usually molded in advance, and then the desired length is obtained through a cutting operation using a high-speed cutting machine or a plasma cutting machine with an abrasive disk. As described above, it is difficult to perform efficient production with such a molding method.

  The roll molded plate-like body of the present invention has a length as shown in FIG. 3 simply by bending the plate material itself with the planned fracture line 4 as a base point after the roll-formed plate-like body is molded, and cutting the narrow piece 4a. The plate-shaped body is cut into short plate-like bodies, and the cut-out plate-like body does not require a complicated cutting operation as in the prior art and can be used as a product as it is.

  Reference numeral 8 denotes a puncher which is disposed on the entry side of the roll molding machine 7 and forms the planned fracture line 4 on the plate 5 '. As the puncher 8, for example, a press type equipped with a punching die can be used. However, the type of the puncher 8 is not particularly limited as long as the planned fracture line 4 can be efficiently formed.

  In order to manufacture a roll-formed plate-like body as shown in FIG. 1 using such a manufacturing equipment row, first, a puncher 8 applies a plate material 5 ′ discharged from the steel plate coil 5 to FIG. 5. A planned fracture line 4 as shown is formed. Then, the plate material 5 ′ may be passed through the roll molding machine 7 and molded.

  Here, the planned fracture line 4 is shown as an example in which the end shape after the roll-formed plate-like body is cut off is provided with an inclination angle, but the planned fracture line 4 is shown in FIGS. The line type and shape as shown in FIG. 11 can also be used, and the arrangement form and planar shape of the narrow piece 4a and the through hole 4b of the planned breaking line 4 are the same as those of the plate material used as a product. Various modifications are made according to the purpose of use, and the present invention is not limited to the illustrated one. In addition, the code | symbol 4c in FIG. 9, 11 has displayed the notch.

  Moreover, it cannot be overemphasized that the fracture | rupture planned line 4 is arbitrarily formed according to the length of a desired roll molding plate-shaped object.
