足場構築体は、先行手摺等に代表されるように、作業の安全のための手摺装置を設置することが一般的とされている。そこで、支保工においても、連結支持機構Ｓ２の構築や、支保工サポートＳ３の構築に際して、作業者の安全を期するための手摺装置を設けることが望ましい。 As represented by a preceding handrail and the like, it is common for a scaffold construction body to be installed with a handrail device for work safety. Therefore, also in the support work, it is desirable to provide a handrail device for ensuring the safety of the operator when the connection support mechanism S2 and the support work support S3 are constructed.

この点に関して、特許文献１は、足場支柱の上端部にソケットを挿着し、左右に隣接するソケットの間に手摺を架設する技術を開示している。しかしながら、支保工、つまり、上述の連結支持機構Ｓ２の構築や、支保工サポートＳ３の構築は、ソケットの上にジャッキを挿着することにより、該ソケットの上方領域で行われるため、手摺が作業安全のために機能していない。 In this regard, Patent Document 1 discloses a technique in which a socket is inserted into an upper end portion of a scaffolding column and a handrail is installed between sockets adjacent to the left and right. However, since the support work, that is, the construction of the above-described connection support mechanism S2 and the support work support S3 are performed in the upper region of the socket by inserting a jack on the socket, the handrail is operated. Not functioning for safety.

At that time, a support fitting with a jack is inserted into the upper end of the scaffolding column as described above. For this reason, the attachment means of the handrail support column must use the fastening means provided on the peripheral side portion of the scaffold support column.

しかしながら、足場支柱の緊結手段に対して、手摺支柱に設けたブラケットを緊結する場合、手摺支柱の支持が片持ち状態となるので、手摺装置の取付強度に問題を生じる可能性がある。 However, when the bracket provided on the handrail support is fastened to the fastening means of the scaffold support, the support of the handrail support is in a cantilever state, which may cause a problem in the attachment strength of the handrail device.

特に、足場支柱の上端部の領域は、支持金具のジャッキ用ハンドルの旋回空間や、大引きが搭載される支持金具の受部により占められているので、これらと干渉しないように手摺支柱を足場支柱から離間した片持ち状態で、しかも、強固に支持することができる構造を提供する必要があり、困難な課題を提起することになる。 In particular, the area of the upper end of the scaffolding strut is occupied by the swivel space of the jack handle of the support bracket and the support bracket receiving portion on which the large pull is mounted. It is necessary to provide a structure that can be firmly supported in a cantilever state separated from the support column, which poses a difficult problem.

The support bracket 20 provided separately below the binding bracket 19 is brought into contact with the surface of the scaffolding column 1 so that it can be installed in a stable state free from grazing.

足場支柱１に設置される柱脚部１７Ａから上方に長く延びる柱頭部１７Ｂは、手摺桟１８を緊結するための楔孔等の緊結部２１ａを備えたフランジ等から成る緊結手段２１を固設している。図示実施形態の場合、単管から成る手摺桟１８の両端部は、緊結部２１ａの楔孔に楔片を打ち込むことにより手摺支柱１７に連結固着される楔緊結式が採用されているが、これに限定されるものではなく、楔緊結式とは異なる形式の締結手段を採用しても良い。 The column head portion 17B extending long upward from the column base portion 17A installed on the scaffolding column 1 is fixedly provided with a fastening means 21 including a flange having a fastening portion 21a such as a wedge hole for fastening the handrail bar 18. ing. In the case of the illustrated embodiment, the both ends of the handrail bar 18 made of a single pipe adopts a wedge-tightening type that is connected and fixed to the handrail strut 17 by driving a wedge piece into the wedge hole of the binding portion 21a. However, the fastening means may be of a type different from the wedge-tightening type.

前記緊結ブラケット１９は、図５及び図６（Ｂ）に示すように、手摺支柱１７の柱脚部１７Ａと足場支柱１の間において、柱脚部１７ＡからＸ方向に延びる基台２２と、足場支柱１の緊結手段４から前記Ｘ方向に交差するＹ方向に延びる緊結部２３を備えており、緊結部２３に設けた楔片により前記緊結手段４に緊結される。図示実施形態の場合、前記基台２２と緊結部２３は、平面視を直角三角形とされた継手部２４を介して連結されている。基台２２、継手部２４、緊結部２３は、それぞれ金属板を折曲することにより形成されており、図５（Ｂ）に示すように、手摺支柱１７に対して、順に、基台２２、継手部２４、緊結部２３が溶接等により固着される。 As shown in FIGS. 5 and 6B, the binding bracket 19 includes a base 22 extending in the X direction from the column base 17A between the column base 17A of the handrail support 17 and the scaffold support 1, and a scaffold. A fastening portion 23 extending in the Y direction intersecting the X direction from the fastening means 4 of the support 1 is provided, and is fastened to the fastening means 4 by a wedge piece provided in the fastening portion 23. In the case of the illustrated embodiment, the base 22 and the fastening portion 23 are connected via a joint portion 24 that is a right triangle in plan view. The base 22, the joint portion 24, and the binding portion 23 are formed by bending metal plates, respectively. As shown in FIG. 5B, the base 22, The joint portion 24 and the tightening portion 23 are fixed by welding or the like.

A separation distance L2 is formed. At this time, as shown in FIG. 6C, the separation distance L1 in the X direction is set so that the handrail support column 17 is installed at a position that does not overlap the outer surface of the receiving portion 6 in the X direction. The Y-direction separation distance L2 is the position where the inner surface of the handrail support column 17 is made to approach the large pull 7 from the outer surface of the receiving portion 6 with respect to the Y direction, that is, the distance L2 is approached. It is set to be installed at a position close to the large pull 7.

その結果、緊結部２３を足場支柱１の緊結手段４に緊結した状態において、手摺支柱１７は、図６（Ｃ）に示すように、大引き７を支持するための受部６や、パイプサポート３の台板１５に干渉しない位置に配置され、更に、図６（Ｄ）に示すように、ジャッキ用ハンドル８の旋回軌跡の外側に配置され、連結支持機構Ｓ２及び支保工サポートＳ３の構築を妨げることはない。 As a result, in the state in which the binding portion 23 is fastened to the fastening means 4 of the scaffolding strut 1, the handrail strut 17 has a receiving portion 6 for supporting the large pull 7 and a pipe support as shown in FIG. 3 is arranged at a position where it does not interfere with the base plate 15, and further, as shown in FIG. 6D, it is arranged outside the turning locus of the jack handle 8, and the connection support mechanism S2 and the support support S3 are constructed. There is no hindrance.

因みに、図７は、足場支柱１の上に挿着するジャッキ付き支持金具５の受部６が２本の大引き７、７を支持可能とするダブルサイズとされている場合に用いられる手摺支柱１７を示している。この場合、緊結ブラケット１９は、足場支柱１と手摺支柱１７の軸心の離間距離（上記のＬ１及びＬ２）を図示するようなＸ方向の離間距離ＬＬ１とＹ方向の離間距離ＬＬ２のように大きく形成している。図６と図７を比較すると明らかなように、このような離間距離の相違は、緊結ブラケット１９における継手部２４のサイズを変更するだけで可能であり、その他の構成は変更の必要がない。 Incidentally, FIG. 7 shows a handrail column used when the receiving portion 6 of the support metal fitting 5 with a jack that is inserted on the scaffold column 1 is of a double size that can support the two large pulls 7 and 7. 17 is shown. In this case, the binding bracket 19 is as large as the separation distance LL1 in the X direction and the separation distance LL2 in the Y direction as shown in the figure, the separation distance between the shaft centers of the scaffolding strut 1 and the handrail strut 17 (L1 and L2 above). Forming. As is apparent from a comparison between FIG. 6 and FIG. 7, such a difference in the separation distance is possible only by changing the size of the joint portion 24 in the fastening bracket 19, and other configurations do not need to be changed.

前記支持ブラケット２０は、手摺支柱１７の中心と足場支柱１の中心を結ぶ傾斜連結線Ｑ（図６（Ｂ）及び図７（Ｂ）参照）に沿って延びるアーム部２５と、該アーム部２５の先端に位置して足場支柱１の外周面に当接する当接部２６を備えている。アーム部２５は、金属板を手摺支柱１７の下端側部に溶接等で固着することにより形成され、当接部２６は、足場支柱１の周面に適合する円弧状の金属板を前記アーム部２５の先端に溶接等で固着することにより形成される。 The support bracket 20 includes an arm portion 25 extending along an inclined connecting line Q (see FIGS. 6B and 7B) connecting the center of the handrail column 17 and the center of the scaffold column 1, and the arm unit 25. The contact part 26 which contacts the outer peripheral surface of the scaffolding pillar 1 is provided. The arm portion 25 is formed by fixing a metal plate to the lower end side portion of the handrail support column 17 by welding or the like, and the abutting portion 26 is an arc-shaped metal plate that fits the peripheral surface of the scaffold support column 1. It is formed by being fixed to the tip of 25 by welding or the like.

上記のように手摺支柱１７を足場支柱１に取着し、互いに隣り合う手摺支柱１７、１７を手摺桟１８で連結することにより、図８ないし図１０に示すように、連結支持機構Ｓ２の周側部のうち、Ｘ１方向に沿う手摺装置１６Ａと、Ｘ２方向に沿う手摺装置１６Ｂが設置され、連結支持機構Ｓ２を好適に囲み、連結支持機構Ｓ２の構築や支保工サポートＳ３の構築の際の作業の安全を約束する。 By attaching the handrail support column 17 to the scaffolding support column 1 and connecting the adjacent handrail support columns 17 and 17 with the handrail bar 18 as described above, as shown in FIGS. Among the side portions, a handrail device 16A along the X1 direction and a handrail device 16B along the X2 direction are installed, and suitably surround the connection support mechanism S2, and when the connection support mechanism S2 is constructed or the support support S3 is constructed. Promises work safety.

手摺桟１８を連結するための緊結手段２１は、手摺支柱１７の柱頭部１７Ｂに上下間隔をあけて複数個を設けることが好ましく、これにより、単管から成る手摺桟１８を上下平行に配置した柵状の手摺装置を提供することができる。 It is preferable that a plurality of fastening means 21 for connecting the handrail bars 18 are provided on the column head portion 17B of the handrail support column 17 with a vertical interval therebetween, whereby the handrail bars 18 made of a single tube are arranged in parallel vertically. A rail-like handrail device can be provided.

この際、前記緊結手段２１は、図５及び図６（Ｂ）に示すように、手摺支柱１７の外周に関して支保工サポートＳ３に臨む側を内側ＹＳとし、その反対側を外側としたとき、手摺支柱１７の外側面に接するＸ方向の接線ＸＬから内側ＹＳにのみ位置して設けることが好ましい。手摺支柱１７の周方向に間隔をあけて３個の楔孔から成る緊結部２１ａを設けたフランジにより緊結手段２１を形成した図示実施形態の場合、緊結部２１ａは、手摺支柱１７の外周面のうち、Ｘ方向の両側面と、ＹＳ側の面にのみ設けられており、外側には突起物が形成されないように構成している。 At this time, as shown in FIG. 5 and FIG. 6 (B), the binding means 21 has a handrail when the side facing the support support S3 with respect to the outer periphery of the handrail support column 17 is the inside YS and the opposite side is the outside. It is preferable to be provided only on the inner side YS from the tangent line XL in the X direction in contact with the outer surface of the support column 17. In the case of the illustrated embodiment in which the fastening means 21 is formed by a flange provided with a fastening portion 21 a made up of three wedge holes at intervals in the circumferential direction of the handrail support column 17, the fastening portion 21 a is formed on the outer peripheral surface of the handrail support post 17. Of these, it is provided only on both side surfaces in the X direction and on the surface on the YS side, and is configured such that no protrusion is formed on the outside.

これにより、手摺装置１６は、手摺支柱１７及び手摺桟１８の外側には突起物を有しないものとして構成される。しかも、上述のような緊結ブラケット１９により、手摺支柱１７が偏位距離Ｄだけ大引き７に近接させられた位置に設置されているので、接線ＸＬが支保工サポートＳ３の上方空間から大きくはみ出すこともない。このため、支保工サポートＳ３の側方にコンパネから成る壁体等の構築物が臨んでいるときでも、手摺装置１６を該構築物に可及的近接状態で組付けることが可能になる。 As a result, the handrail device 16 is configured as having no protrusions on the outside of the handrail support column 17 and the handrail bar 18. Moreover, since the handrail support column 17 is installed at a position close to the large pull 7 by the displacement distance D by the tightening bracket 19 as described above, the tangent line XL protrudes greatly from the upper space of the support support S3. Nor. For this reason, even when a structure such as a wall made of a panel faces the side of the support support S3, the handrail device 16 can be assembled to the structure as close as possible.

上述のように、手摺支柱１７の緊結ブラケット１９は、足場支柱１に取着された状態で、手摺支柱１７を足場支柱１からＸ方向の離間距離Ｌ１とＹ方向の離間距離Ｌ２だけ離間した位置に設置するので、手摺支柱１７がジャッキ用ハンドル８に干渉せず、しかも、大引き７の受部６やパイプサポート３の台板１５にも干渉することがなく、手摺装置１６が設置された後における連結支持機構Ｓ２の構築と支保工サポートＳ３の構築を好適に実行可能とする。 As described above, the binding bracket 19 of the handrail support column 17 is attached to the scaffolding support column 1, and the handrail support column 17 is separated from the scaffold support column 1 by the separation distance L1 in the X direction and the separation distance L2 in the Y direction. The handrail device 16 is installed without the handrail support column 17 interfering with the jack handle 8 and without interfering with the receiving portion 6 of the large pull 7 or the base plate 15 of the pipe support 3. The construction of the connection support mechanism S2 and the construction of the support support S3 can be suitably executed later.

更に、Ｘ方向の基台２２とＹ方向の緊締部２３による緊結ブラケット１９のＬ形構成と、手摺支柱１７と足場支柱１の中心を結ぶ傾斜連結線Ｑに沿うアーム部２５を介して当接部２６を足場支柱１の周面に当接させる支持ブラケット２０の傾斜構成は、その両者が相俟って、手摺装置１６の設置強度を確保するために貢献する。 Further, the L-shaped configuration of the fastening bracket 19 by the base 22 in the X direction and the fastening portion 23 in the Y direction, and the arm portion 25 along the inclined connection line Q connecting the center of the handrail column 17 and the scaffold column 1 are contacted. The inclined configuration of the support bracket 20 that causes the portion 26 to contact the peripheral surface of the scaffolding column 1 contributes to securing the installation strength of the handrail device 16 together.

図１１（Ａ）は、作業者が寄りかかる等、手摺支柱１７及び手摺桟１８に対して、連結支持機構Ｓ２の上から足場構築体の外側に向かう力Ｆ１が与えられた場合を示している。この場合、前述のＬ形構成とされた緊結ブラケット１９により、Ｘ方向と平行なＸ軸廻りのモーメントＭ１が生じる。その結果、手摺支柱１７の下端部を矢印Ｐ１に向けて揺動させようとするが、矢印Ｐ１に向かう力は、支持ブラケット２０により足場支柱１の周面に堅固に支持されるので、手摺装置１６が設置姿勢を崩すことはない。 FIG. 11A shows a case where a force F1 is applied to the handrail support column 17 and the handrail bar 18 from the top of the connection support mechanism S2 toward the outside of the scaffold structure, such as when an operator leans on. In this case, a moment M1 around the X axis parallel to the X direction is generated by the binding bracket 19 having the L-shaped configuration described above. As a result, the lower end portion of the handrail column 17 tries to swing toward the arrow P1, but the force directed to the arrow P1 is firmly supported by the support bracket 20 on the peripheral surface of the scaffold column 1, so the handrail device 16 does not break the installation posture.

図１１（Ｂ）は、作業者が手で押さえる等、手摺支柱１７及び手摺桟１８に対して、下向きの力Ｆ２が与えられた場合を示している。この場合、前述のＬ形構成とされた緊結ブラケット１９により、Ｙ方向と平行なＹ軸廻りのモーメントＭ２が生じる。その結果、手摺支柱１７の下端部を矢印Ｐ２に向けて揺動させようとするが、矢印Ｐ２に向かう力は、支持ブラケット２０により足場支柱１の周面に堅固に支持されるので、手摺装置１６が設置姿勢を崩すことはない。 FIG. 11B shows a case where a downward force F2 is applied to the handrail column 17 and the handrail bar 18 such as when the operator holds the hand. In this case, a moment M2 around the Y axis parallel to the Y direction is generated by the fastening bracket 19 having the L-shaped configuration described above. As a result, the lower end portion of the handrail column 17 tries to swing toward the arrow P2, but the force directed to the arrow P2 is firmly supported by the support bracket 20 on the peripheral surface of the scaffold column 1, so the handrail device 16 does not break the installation posture.

これにより手摺装置１６は、本来の安全手摺としての機能を好適に果たすことができ、作業者の作業安全性を確保する。 Thereby, the handrail device 16 can suitably fulfill the function as an original safety handrail, and ensure the work safety of the operator.
