Description

産業上の利用分野Industrial application fields

薄鋼板波板および薄鋼板カラー波板の曲げ加工は、パイプハウス等に設ける多用途利用の曲げ薄鋼板波板であり、波板張りパイプハウスの保温構成（特許出願番号２００５−２５６７１号）に設ける曲げ薄鋼板波板である。  The bending of the thin steel plate corrugated sheet and the thin corrugated sheet color corrugated sheet is a versatile bent thin steel sheet corrugated sheet provided in a pipe house or the like, and the thin bending sheet provided in the heat retaining structure of the corrugated sheet pipe house (Patent Application No. 2005-25671). It is a steel plate corrugated sheet.

従来の薄鋼板波板および薄鋼板カラー波板には、曲げ加工および曲げ波板はなかった。  Conventional thin steel sheet corrugated sheets and thin steel sheet color corrugated sheets have no bending and bending corrugated sheets.

発明が解決しようとする課題点Problems to be solved by the invention

アーチ形等のパイプハウスはフィルムを設ける構成であり、薄鋼板波板および薄鋼板カラー波板（以下、薄鋼板波板と記述する）を設けることは少なかった。樹脂波板をパイプハウスに設ける場合には曲げ加工を必要としないのであるが、薄鋼板波板では折れが生じる欠点があった。したがって、パイプハウス等に設ける薄鋼板波板の曲げ加工が必要であり、曲げ加工に関する開発をしようとするものである。  An arched pipe house or the like has a structure in which a film is provided, and a thin steel sheet corrugated sheet and a thin steel sheet color corrugated sheet (hereinafter referred to as a thin steel sheet corrugated sheet) are rarely provided. When the resin corrugated sheet is provided in the pipe house, bending is not necessary, but the thin steel sheet corrugated sheet has a drawback in that it bends. Therefore, it is necessary to bend a thin steel plate corrugated sheet provided in a pipe house or the like, and it is intended to develop a bending process.

２・曲面盤４および駆動ローラー３を曲面に設け、波形状ベルト５を設ける。
３・最終曲面には曲げを必要とする半径の曲面を設ける。
４・曲面盤４の表面に多数の小円形状等のディンプル（くぼみ）を設ける。
５・波形状ベルトの低速回転による薄鋼板波板の曲げ加工。1. A roller 2 and a driving roller 3 provided at a minimum interval are provided on a curved surface, and a corrugated belt 1 is provided.
2. The curved disk 4 and the driving roller 3 are provided on the curved surface, and the corrugated belt 5 is provided.
3. A curved surface with a radius that requires bending is provided on the final curved surface.
4. A large number of small circular dimples (recesses) are provided on the surface of the curved disk 4.

作用Action

アーチ形等のパイプハウスに設ける薄鋼板波板の曲げ加工は、曲面に設けた上下の波形状ベルト１と５の低速回転により、薄鋼板波板を銜え曲げてゆくのである。この波形状ベルト１または５には、最小間隔に設けたローラー２または曲面盤４を設けて駆動ローラー３により波形状ベルト１または５を回転するものである。最小間隔に設けたローラー２または曲面盤４は、波形状ベルトのたわみを防ぎ、薄鋼板波板の曲げ加工時による変形および折れ等を防ぐのである。また、曲面盤４に設けた多数のディンプルは波形状ベルト５の摩擦抵抗を軽減するものである。  The bending process of the thin steel plate corrugated sheet provided in the arched pipe house is made by bending the thin steel sheet corrugated sheet by the low-speed rotation of the upper and lower corrugated belts 1 and 5 provided on the curved surface. The corrugated belt 1 or 5 is provided with a roller 2 or a curved disk 4 provided at a minimum interval, and the corrugated belt 1 or 5 is rotated by the driving roller 3. The roller 2 or the curved disk 4 provided at the minimum interval prevents the corrugated belt from being bent, and prevents deformation and bending of the thin steel sheet corrugated sheet during bending. Further, a large number of dimples provided on the curved disk 4 reduce the frictional resistance of the corrugated belt 5.

したがって、最小間隔のローラー２および駆動ローラー３を曲面に設け、波形状ベルト１の低速回転により薄鋼板波板を曲げ加工するものである。このように曲げ加工した薄鋼板波板をアーチ形等のパイプハウスの屋根および桁行の肩部や棟に設けるのである。An embodiment of claim 1 will be described.
Bending of a thin steel plate corrugated sheet in which a corrugated belt 1 is provided on a roller 2 and a driving roller 3 provided on a curved surface.
When steel corrugated sheets (named from the Building Practice Glossary) are installed on the roof of an arched pipe house, bending work is required, especially the shoulders of the girders (named underground push-in pipe house safety structure) The bending process (from the guideline) is important. In this bending process of the thin steel sheet corrugated sheet, the roller 2, the driving roller 3, and the corrugated belt 1 are provided. The bending process is the roof of the pipe house such as an arch shape and the shoulders of the beam. The curved surface provided on the roller 2 and the driving roller 3 provided at the minimum interval is provided with a radius that requires bending on the final curved surface.
Therefore, the roller 2 and the driving roller 3 with the minimum interval are provided on the curved surface, and the thin steel plate corrugated sheet is bent by the low speed rotation of the corrugated belt 1. The thin steel plate corrugated sheet thus bent is provided on the roof of an arched pipe house or the shoulder or ridge of a girder.

したがって、曲面盤４および駆動ローラーを曲面に設けて波形状ベルト５の低速回転により、薄鋼板波板を曲げ加工するのである。An embodiment of claim 2 will be described.
Bending of a thin steel plate corrugated sheet provided with a corrugated belt 5 and a curved roller 4 and a driving roller 3 on a curved surface.
When a thin steel plate corrugated sheet is provided in an arch-shaped pipe house, it is necessary to bend the thin steel sheet corrugated sheet at the roof and the shoulder of the girder, and the bending at the shoulder of the girder is particularly important. For bending the thin steel plate corrugated sheet, the curved disk 4 and the driving roller 3 are provided on the curved surface, and the corrugated belt 5 is provided. The bending process of the thin steel plate corrugated plate is the shoulders and roofs or ridges of the girders in the arch-shaped pipe house, and the curved surfaces of the curved disk 4 and the driving roller 3 are provided with a radius that requires bending on the final curved surface.
Therefore, the curved plate 4 and the driving roller are provided on the curved surface, and the corrugated belt 5 is bent by the low speed rotation of the corrugated belt 5.

薄鋼板波板の曲げ加工に設ける曲面盤４の表面には、小円形状等のディンプル（くぼみ）を多数設けるのである。この曲面盤４の表面に設けたディンプルは、低速回転による波形状ベルト５との抵抗の軽減である。
したがって、曲面盤４の表面に小円形状等のディンプル（くぼみ）を多数設けて、波形状べルト５との摩擦抵抗を少なくし、薄鋼板波板を曲げ加工するものである。An embodiment of claim 3 will be described.
Bending of a thin steel plate corrugated sheet having dimples (indentations) on the surface of the curved disk 4.
A large number of dimples (hollows) such as small circles are provided on the surface of the curved plate 4 provided for bending the thin steel plate corrugated sheet. The dimples provided on the surface of the curved disk 4 reduce the resistance with the corrugated belt 5 by low-speed rotation.
Therefore, a large number of small circular dimples (indentations) are provided on the surface of the curved surface board 4 to reduce the frictional resistance with the corrugated belt 5 and bend the thin steel sheet corrugated sheet.
