PRECEDING HANDRAIL OF TEMPORARY STRUCTURE
PROBLEM TO BE SOLVED: To provide a preceding handrail having a hook contacting an outer surface of a support post in a pressurizing state when assembled, the hook never falling out from a flange hole, thereby ensuring work safety.SOLUTION: A horizontal part of a preceding handrail is pivoted rotatably on an engaging hook 7 fastened on a tip part 61 on a top part of a diagonal material 6 or on the diagonal material 6. When assembling, the diagonal material 6 is inserted into a hole of a flange and installed at a prescribed angle while intersecting in an X-form with the other diagonal material. When fixing, a rotary part 73 provided on an inner side of the engaging hook 7 rotates around an outside wall 22 of the hole of the flange, and a contact part 75 is provided on an appropriate location on an outer peripheral part 74 of the engaging hook 7 that presses an outer periphery of a support post in a pressurizing state as the diagonal material 6 rotates. When the preceding handrail has been assembled, the contact part 75 of the engaging hook 7 of both diagonal materials 6 butts against the outside wall 22 of the hole of the flange, to maintain the pressurizing state on the outer periphery of the support post.SELECTED DRAWING: Figure 4
【課題】組み立てた際にはフックが支柱の外面に加圧状態で当接して、フックがフランジ孔から抜け出すことがなく、作業の安全性を確保できる先行手摺りを提供する。【解決手段】先行手摺りの水平部は、斜材６の上方の先端部６１或いは斜材６に固着された係止フック７に回動可能に軸支され、組み立て時には互いにＸ字状に交叉する状態で、斜材６がフランジの孔に挿入され所定の角度で架設され固定する際には、係止フック７は内側に設けた回動部７３がフランジの孔の外側壁２２を中心に回動するとともに、該係止フック７の外周部７４の適所には斜材６の回動に伴って支柱外周を加圧状態で押圧する当接部７５を設け、先行手摺りを組み上げた状態では、両斜材６の係止フック７の前記当接部７５が前記フランジの孔の外側壁２２に対して突っ張るように支柱外周に加圧状態に維持する先行手摺り。【選択図】図４
