しかし、支柱を足場板に溶接して固定する方法では、支柱を固定しようとする足場板の下方に機械設備等が有る場合、足場板の下方に溶接の火花が落下するのを防ぐための火気養生をする必要があった。また、支柱のベースプレートを足場板にボルトで締結して固定する方法では、支柱を固定しようとする足場板の下方に作業スペース等が有る場合、固定用ナットを足場板の下側から押さえるための他の仮設足場を設ける必要があった。このため、支柱を固定しようとする足場板の下方の空間の利用に制限が生じていた。例えば、支柱を足場板に固定する作業中に、足場板の下方の空間における生産活動を停止する必要があった。また、これとは逆に、支柱を固定しようとする足場板の下方に製造ライン等が存在し、これを停止できない場合には、足場板に支柱を取り付ける作業を実施することが困難であった。 However, in the method of fixing the post to the scaffolding board by welding, if there is machinery below the scaffolding board to which the post is to be fixed, fire is required to prevent welding sparks from falling below the scaffolding board. I needed to nurture. In addition, in the method of fixing the base plate of the post to the scaffolding board with bolts, if there is work space below the scaffolding board to which the post is to be fixed, the fixing nut must be held down from the underside of the scaffolding board. Other temporary scaffolding had to be provided. For this reason, the use of the space under the scaffold board to which the support is to be fixed is restricted. For example, it was necessary to stop production activities in the space below the scaffolding board during the work of fixing the posts to the scaffolding board. Conversely, if there is a production line or the like below the scaffolding board to which the support is to be fixed, and this cannot be stopped, it is difficult to carry out the work of attaching the support to the scaffolding board. .

上記課題を解決するため、本発明は、手摺等の支柱を足場板に固定する際に、足場板の下方に火気養生や他の仮設足場を設ける必要がなく、足場板の上面側からの作業のみで支柱を簡単に固定することのできる、支柱の固定構造及び支柱の固定方法を提供することを目的とする。 In order to solve the above problems, the present invention eliminates the need to provide fire protection or other temporary scaffolding under the scaffolding board when fixing a support such as a handrail to the scaffolding board, thereby enabling work from the upper surface side of the scaffolding board.

また、第一の固定部材又は第二の固定部材として用いた板金ビス１２、１３、２３、３３やフックボルト２２、Ｕ字フックボルト３２の組み合わせも上記実施形態には限らない。例えば、第２実施形態及び第３実施形態において、ベースプレート３０を支持材７に固定する第二の固定部材として、板金ビス２３、３３ではなくＵ字フックボルトを用いてもよい。この場合、Ｕ字フックボルトを挿入するための開口を支持材７に予め形成しておくことが好ましい。 Further, the combinations of the sheet metal screws 12, 13, 23, 33, the hook bolts 22, and the U-shaped hook bolts 32 used as the first fixing member or the second fixing member are not limited to those of the above embodiments. For example, in the second and third embodiments, U-shaped hook bolts may be used instead of the sheet metal screws 23 and 33 as the second fixing member for fixing the base plate 30 to the support member 7 . In this case, it is preferable to previously form an opening in the support member 7 for inserting the U-shaped hook bolt.

本発明の支柱の固定構造及び支柱の固定方法を適用して足場板の上に支柱を固定する場合について、施工試験を行い、従来の支柱の固定構造及び支柱の固定方法により足場板の上に支柱を固定した際の過去実績との施工費用および足場板の下方の空間の利用制限日数を比較して、本発明の効果を検証した。 In the case of fixing a support post on a scaffolding board by applying the support fixing structure and support fixing method of the present invention, a construction test was conducted, and the conventional support fixing structure and support fixing method were applied to the scaffolding board. The effect of the present invention was verified by comparing the construction cost and the limited number of days of use of the space under the scaffold board with the past results when the support was fixed.

本施工試験では、工場内の上部クレーンの点検歩廊の床板を構成する足場板を対象とした。そして、点検歩廊の全長２２０ｍの区間のうち、既存の手摺が設けられている部分を除くチェッカープレート１９ｍとエキスパンドメタル１４３ｍの計１６２ｍの区間の各々に手摺用の支柱を固定した（本発明例）。 In this construction test, the target was a scaffold board that constitutes the floor board of the inspection corridor of the upper crane in the factory. Then, of the 220m long section of the inspection corridor, 19m of the checker plate and 143m of expanded metal, excluding the portion where the existing handrail is provided, for a total of 162m, was fixed to each of the sections for handrails (example of the present invention). .

チェッカープレートの区間（１９ｍ）に対しては、本発明の第１実施形態の支柱の固定構造及び支柱の固定方法を適用した。 The column fixing structure and column fixing method of the first embodiment of the present invention were applied to the section (19 m) of the checker plate.

また、エキスパンドメタルの区間（１４３ｍ）に対しては、本発明の第２実施形態の支柱の固定構造及び支柱の固定方法を適用した。なお、本発明例では、１６２ｍの区間に１．１ｍ間隔で１５１本の支柱を設置した。 The column fixing structure and column fixing method of the second embodiment of the present invention were applied to the expanded metal section (143 m). In addition, in the example of the present invention, 151 pillars were installed at intervals of 1.1 m in a section of 162 m.

一方、従来の支柱の固定構造及び支柱の固定方法（過去実績）では、各支柱の下端部を支持材に溶接する方法により、本発明例と同じ本数の支柱を設置した（従来例）。なお、従来例では、足場板の下方に火気養生を行った。 On the other hand, in the conventional column fixing structure and column fixing method (past results), the same number of columns as in the example of the present invention were installed by welding the lower end of each column to the support material (conventional example). In addition, in the conventional example, fire curing was performed under the scaffold board.

この結果、本発明例の施工費用は、従来例の２．５分の１となり、施工費用が大幅に抑えられることが確認された。また、従来例では、足場板の下方の空間について１０日間に亘って利用制限する必要が生じ、点検歩廊の下方の製造ラインを停止する等、工場の生産活動に影響を生じたのに対し、本発明を適用した場合はこのような利用制限が生じなかった。 As a result, it was confirmed that the construction cost of the example of the present invention was reduced to 1/2.5 of that of the conventional example, and that the construction cost could be greatly reduced. In addition, in the conventional example, it was necessary to restrict the use of the space under the scaffolding board for 10 days, which affected the production activities of the factory, such as stopping the production line under the inspection corridor. When the present invention was applied, such use restrictions did not arise.
