When the nut is screwed in the state where it is engaged with the pipe from the side, the pressing member presses and fixes the outer edge of the scaffolding plate to the single pipe, but the pressing member is fixed to the outer edge of the scaffolding plate. When the engaging member is engaged with the single pipe pipe from the lateral direction so as to be along the upper surface corner of the section, the engaging member is pushed forward from the rear side of the single pipe pipe. In the state where the engaging member is engaged with the single pipe, the engaging member is locked to the single pipe by the locking claw, so that the pressing member presses the scaffold plate against the single pipe. Even if it is not, the metal fittings will not fall out of the single pipe pipe, which is safe Reliably and easily it can be fixed anchorage plate to single tube pipe.

また、足場を解体する際は、ナットを緩めて足場板の押圧状態を解除した後、金具の係止爪を非係止位置に回動させた状態で、係合部材を単管パイプから離反する方向にスライドさせて単管パイプとの係合を解除すればよいので、単管パイプに対する足場板の固定解除作業も簡単に行うことができる。   When disassembling the scaffold, loosen the nut to release the pressed state of the scaffold plate, and then move the engagement member away from the single pipe pipe with the locking claw of the bracket turned to the non-locking position. Since it is sufficient to release the engagement with the single pipe pipe by sliding in the direction to be fixed, it is possible to easily perform the fixing release operation of the scaffold plate with respect to the single pipe pipe.

特に、請求項６に係る発明の金具のように、押圧部材の角部における足場板の上面に対応する部分から足場板の側端面に対応する部分に渡って、軸部材が挿通される長孔を形成しておくと、ナットを外すことなく、軸部材の挿通位置を変更することができ、足場板の上面に対応する部分を足場板の側端面に対応する部分に、足場板の側端面に対応する部分を足場板の上面に対応する部分に入れ替えた状態で押圧部材を使用することが可能となる。従って、使用する足場板の厚みに合わせて、両部分の張出し長さをそれぞれ異なる長さに設定しておくと、厚みの異なる足場板に対応することができる。   In particular, like the metal fitting of the invention according to claim 6, a long hole through which the shaft member is inserted from a portion corresponding to the upper surface of the scaffold plate at a corner portion of the pressing member to a portion corresponding to the side end surface of the scaffold plate. If it is formed, the insertion position of the shaft member can be changed without removing the nut, and the portion corresponding to the upper surface of the scaffold plate is changed to the portion corresponding to the side end surface of the scaffold plate, and the side end surface of the scaffold plate It is possible to use the pressing member in a state where the portion corresponding to is replaced with the portion corresponding to the upper surface of the scaffold plate. Therefore, if the lengths of the protruding portions of the two portions are set to different lengths in accordance with the thickness of the scaffold plate to be used, it is possible to deal with scaffold plates having different thicknesses.

The operation portion 33 has a central hole 33a that can be inserted into the upper end portion of the shaft member 12 and that coincides with the insertion hole 31a of the base plate 31.

以上のように構成された金具１及び操作治具３を用いて足場枠を構成している単管パイプの上に掛け渡した隣接する２枚の足場板を単管パイプに固定する足場板の固定方法について、図９〜図１４を参照しながら説明する。   A scaffold plate for fixing two adjacent scaffold plates spanned on a single pipe constituting the scaffold frame using the metal fitting 1 and the operation jig 3 configured as described above to the single pipe. The fixing method will be described with reference to FIGS.

まず、図９（ａ）〜（ｃ）に示すように、固定済みの足場板ＳＰに一方の側縁を当接させるように新たな足場板ＳＰを単管パイプＰの上に掛け渡した後、図１０（ａ）〜（ｃ）に示すように、金具１の押圧板１３を軸部材１２の最上位に移動させ、その押圧板１３を足場板ＳＰの上側に位置させた状態で、２個の金具１を足場板ＳＰの他方の側縁に沿わせてスライドさせることによって、それぞれの係合部材１１を足場板ＳＰの長手方向の両端側に位置する２本の単管パイプＰにそれぞれ係合させる。   First, as shown in FIGS. 9A to 9C, after a new scaffold plate SP is placed over the single pipe P so that one side edge is brought into contact with the fixed scaffold plate SP. 10 (a) to 10 (c), the pressing plate 13 of the metal fitting 1 is moved to the uppermost position of the shaft member 12, and the pressing plate 13 is positioned above the scaffolding plate SP. By sliding the metal fittings 1 along the other side edge of the scaffolding plate SP, the respective engaging members 11 are respectively attached to the two single pipes P located on both ends in the longitudinal direction of the scaffolding plate SP. Engage.

この金具１の係合部材１１を単管パイプＰに横方向から係合させる際は、図１１（ａ）〜（ｃ）に示すように、一端側が係止位置に押し上げられている係止爪１５の上面に単管パイプＰが当接することによって、係止爪１５の一端側が係止位置から非係止位置側に押し下げられながら、係止爪１５部分が単管パイプＰの下面を通過し、係合部材１１の半円部１１ａが単管パイプＰに係合する。このようにして、係合部材１１の半円部１１ａが単管パイプＰに係合すると、係止爪１５の一端側がダブルトーションばね１６の付勢力によって元の係止位置に押し上げられ、係止爪１５によって金具１が単管パイプＰに係止されるので、金具１が単管パイプＰから容易に脱落することがない。   When the engaging member 11 of the metal fitting 1 is engaged with the single pipe P from the lateral direction, as shown in FIGS. 11A to 11C, the locking claw whose one end is pushed up to the locking position. When the single pipe P is brought into contact with the upper surface of 15, one end side of the locking claw 15 is pushed down from the locking position to the non-locking position side, and the locking claw 15 part passes through the lower surface of the single pipe P. The semicircular portion 11a of the engaging member 11 is engaged with the single pipe P. When the semicircular portion 11a of the engaging member 11 is engaged with the single pipe P in this way, one end side of the locking claw 15 is pushed up to the original locking position by the urging force of the double torsion spring 16, and the locking Since the metal fitting 1 is locked to the single pipe P by the claw 15, the metal fitting 1 is not easily detached from the single pipe P.

続いて、図１２（ａ）〜（ｃ）に示すように、新たな足場板ＳＰを、その一方の側縁を金具１に当接させるように、単管パイプＰの上に掛け渡した後、図１３（ａ）〜（ｃ）に示すように、操作治具３を、その挿通孔３１ａに金具１の軸部材１２の上端部（ストッパ部材１２ａ）を挿通すると共に、一対の凸部３２を金具１の押圧板１３の嵌合穴１３ｂに嵌合させた状態で、押圧板１３の上に載置し、この操作治具３の操作部３３を、電動ドライバーＥＤ等の工具を用いて回転操作することによって、金具１の押圧板１３を締め込むと、図１４（ａ）〜（ｃ）に示すように、金具１の押圧板１３によって隣接する２枚の足場板ＳＰの側縁部が単管パイプＰに押圧され、金具１を介して隣接する２枚の足場板ＳＰが単管パイプＰに固定される。なお、金具１を用いて足場板ＳＰを単管パイプＰに固定した状態では、軸部材１２の上端部の突出量が５〜２ｍｍ程度になるように、ストッパ部材１２ａを含む軸部材１２の長さが設定されている。   Subsequently, as shown in FIGS. 12A to 12C, after the new scaffolding plate SP is laid over the single pipe P so that one side edge thereof is brought into contact with the metal fitting 1. As shown in FIGS. 13A to 13C, the operation jig 3 is inserted through the insertion hole 31 a through the upper end portion (stopper member 12 a) of the shaft member 12 of the metal fitting 1, and a pair of convex portions 32. Is placed on the pressing plate 13 in a state of being fitted in the fitting hole 13b of the pressing plate 13 of the metal fitting 1, and the operating portion 33 of the operating jig 3 is used with a tool such as an electric screwdriver ED. When the pressing plate 13 of the metal fitting 1 is tightened by rotating, the side edges of the two scaffolding plates SP adjacent to each other by the pressing plate 13 of the metal fitting 1 as shown in FIGS. Is pressed by the single pipe P, and two adjacent scaffold plates SP are fixed to the single pipe P through the metal fitting 1. In addition, in the state which fixed the scaffold board SP to the single pipe P using the metal fitting 1, the length of the shaft member 12 including the stopper member 12a is set so that the protruding amount of the upper end portion of the shaft member 12 is about 5 to 2 mm. Is set.

以上のように、この金具１は、単管パイプＰに係合させる係合部材１１の下側直線部１１ｃに係止ユニット１４が取り付けられており、係合部材１１を単管パイプＰに係合させると、係止ユニット１４の係止爪１５がダブルトーションばね１６によって係止位置に回動し、係止爪１５によって係合部材１１が単管パイプＰに係止されるので、単管パイプＰに一旦係合した係合部材１１の係合状態が容易に解除されることがなく、金具１自体が組立途中の足場から落下するという不測の事態を防止することができる。   As described above, in the metal fitting 1, the locking unit 14 is attached to the lower straight portion 11 c of the engagement member 11 to be engaged with the single pipe P, and the engagement member 11 is engaged with the single pipe P. When combined, the locking claw 15 of the locking unit 14 is rotated to the locking position by the double torsion spring 16, and the engaging member 11 is locked to the single pipe P by the locking claw 15. The engagement state of the engagement member 11 once engaged with the pipe P is not easily released, and it is possible to prevent an unexpected situation that the metal fitting 1 itself falls from the scaffold during assembly.

また、この金具１では、係合部材１１を単管パイプＰに係合させる際、係止爪１５は、単管パイプＰに押圧されることによって係止位置から非係止位置に移動し、係合部材１１が単管パイプＰに係合した時点で、係止位置に復帰するようになっているので、係合部材１１を単管パイプＰに係合させる際に、係止爪１５を非係止位置に移動させるための動作が不要であり、単管パイプＰへの金具の取付作業性が良い。   Further, in the metal fitting 1, when the engaging member 11 is engaged with the single pipe P, the locking claw 15 is moved from the locking position to the non-locking position by being pressed by the single pipe P, When the engaging member 11 is engaged with the single pipe P, the locking member 15 is returned to the locking position. The operation for moving to the non-locking position is unnecessary, and the workability of attaching the metal fitting to the single pipe P is good.

また、この金具１は、係止爪１５が、係止位置から非係止位置に回動させるための操作片１５ｃを有しているので、金具１を単管パイプＰから取り外す際、係止爪１５を、係止位置から非係止位置に容易に回動させることができ、単管パイプＰから金具１を取り外す際の作業性にも優れている。   Further, the metal fitting 1 has an operation piece 15c for allowing the locking claw 15 to rotate from the locking position to the non-locking position. The claw 15 can be easily rotated from the locking position to the non-locking position, and the workability when removing the metal fitting 1 from the single pipe P is excellent.

また、この金具１では、係合部材１１を単管パイプに横方向から係合させる際、押圧板１３を足場板ＳＰの上側に位置させた状態で、足場板ＳＰの側縁に沿わせながらスライドさせることによって係合部材１１を単管パイプＰに係合させればよいので、足場板と単管パイプとを番線で固定する場合のように、単管パイプに掛け渡した足場板の前方側に作業者が身を乗り出す必要がなく、作業者が足場板から転落する危険性が大幅に低減される。   Further, in this metal fitting 1, when the engaging member 11 is engaged with the single pipe pipe from the lateral direction, the pressing plate 13 is positioned on the upper side of the scaffolding plate SP while being along the side edge of the scaffolding plate SP. Since the engaging member 11 has only to be engaged with the single pipe P by sliding, the front of the scaffold plate spanned over the single pipe as in the case where the scaffold plate and the single pipe are fixed with a wire. There is no need for the operator to lean on the side, and the risk of the operator falling from the scaffolding plate is greatly reduced.

また、この金具１を用いて隣接する２枚の足場板ＳＰの側縁部を単管パイプＰに固定するには、上述したように、係合部材１１を単管パイプＰに係合させた状態で、隣接する双方の足場板ＳＰの側縁部に張り出している押圧板１３を回転させてねじ込むだけでよいので、作業者は熟練及び労力を必要とせず、簡単に短時間で足場板ＳＰを単管パイプＰに固定することができる。   Further, in order to fix the side edge portions of the two adjacent scaffold plates SP to the single pipe P using the metal fitting 1, the engaging member 11 is engaged with the single pipe P as described above. In this state, it is only necessary to rotate and screw the pressing plate 13 projecting from the side edges of both adjacent scaffolding plates SP, so that the operator does not need skill and labor and can easily perform the scaffolding plate SP in a short time. Can be fixed to the single pipe P.

また、足場を解体する際は、押圧板１３を逆方向に回転させて２枚の足場板ＳＰの押圧状態を解除した後、外側の足場板ＳＰを外側にずらして２枚の足場板ＳＰ間に手の入る隙間を形成し、図６（ａ）、（ｂ）に示すように、係止爪１５の操作片１５ｃを指でもって係止爪１５の一端側を下方側に押し下げると、単管パイプＰに対する係止爪１５の係止状態が解除されるので、その状態で、係合部材１１を単管パイプＰから離反する方向にスライドさせて単管パイプＰとの係合を解除するだけで、金具１を単管パイプＰから取り外すことができる。従って、単管パイプＰに対する足場板ＳＰの固定解除作業も簡単に行うことができ、取り外した金具１は他の工事現場で繰り返し使用することができる。   Further, when dismantling the scaffold, the pressing plate 13 is rotated in the opposite direction to release the pressing state of the two scaffolding plates SP, and then the outer scaffolding plate SP is shifted to the outside to move between the two scaffolding plates SP. 6A and 6B, when the operation piece 15c of the locking claw 15 is pushed down with one finger and the one end side of the locking claw 15 is pushed downward, Since the locking state of the locking claw 15 with respect to the pipe pipe P is released, in this state, the engagement member 11 is slid away from the single pipe P to release the engagement with the single pipe P. Only the metal fitting 1 can be removed from the single pipe P. Therefore, the fixing operation of the scaffold plate SP with respect to the single pipe P can be easily performed, and the removed metal fitting 1 can be repeatedly used at other construction sites.

また、この金具１を用いて足場板ＳＰを単管パイプＰに固定した状態では、足場板ＳＰ上に押圧板１３が載置され、その押圧板１３の中央部に軸部材１２の上端部が突出することになるが、その突出量が５〜２ｍｍ程度になるように軸部材１２の長さが設定されているので、足場板ＳＰ上を歩行する作業者の障害となることもない。   Further, in a state where the scaffolding plate SP is fixed to the single pipe P using the metal fitting 1, the pressing plate 13 is placed on the scaffolding plate SP, and the upper end portion of the shaft member 12 is at the center of the pressing plate 13. Although it protrudes, since the length of the shaft member 12 is set so that the protruding amount is about 5 to 2 mm, it does not become an obstacle for the worker walking on the scaffolding plate SP.

なお、この金具１では、操作治具３を用いて押圧板１３を締め込んだり、緩めたりするようになっているが、これに限定されるものではなく、手動工具または電動工具を用いて、押圧板１３自体を直接回転させるようにしてもよい。   In this metal fitting 1, the pressing plate 13 is tightened or loosened using the operation jig 3. However, the present invention is not limited to this, and using a manual tool or an electric tool, The pressing plate 13 itself may be directly rotated.

図１５(ａ)〜（ｄ）は、足場枠を構成している単管パイプＰの上に掛け渡した最端位置の足場板の外側縁部を単管パイプＰに固定する金具２を示している。この金具２は、同図に示すように、金具１における軸部材１２の雄ねじ部にねじ込まれる円形状の押圧板１３に代えて、足場板の上面に対応する部分に軸部材１２が挿通される断面逆Ｌ字状の押圧部材２３及び軸部材１２の雄ねじ部にねじ込まれるナット２４を採用している点を除き、基本的に金具１と同一構成を有しているので、同一構成要素には、同一符号を付してその説明を省略し、異なる構成要素について説明する。なお、軸部材１２の長さは、金具１の軸部材１２の長さよりも８ｍｍ程度長く設定されている。   15 (a) to 15 (d) show the metal fitting 2 that fixes the outer edge of the endmost scaffold plate spanned over the single pipe P constituting the scaffold frame to the single pipe P. FIG. ing. In this metal fitting 2, as shown in the figure, the shaft member 12 is inserted into a portion corresponding to the upper surface of the scaffolding plate instead of the circular pressing plate 13 screwed into the male screw portion of the shaft member 12 in the metal fitting 1. Since it has basically the same configuration as that of the metal fitting 1 except that the pressing member 23 having an inverted L-shaped cross section and the nut 24 screwed into the male screw portion of the shaft member 12 are employed, The same reference numerals are attached and the description thereof is omitted, and different components will be described. The length of the shaft member 12 is set to be about 8 mm longer than the length of the shaft member 12 of the metal fitting 1.

前記押圧部材２３は、図１６（ａ）〜（ｃ）に示すように、足場板の側端面に沿う縦板２３ａと、縦板２３ａの上端から水平に張り出して足場板の上端面に沿う横板２３ｂとから構成されており、縦板２３ａの長さ（高さ）Ｌ１は、足場板の厚みより僅かに短めに設定されていると共に、横板２３ｂの張出長さＬ２は、厚みの異なる他の足場板の厚みより僅かに短めに設定されている。   As shown in FIGS. 16 (a) to 16 (c), the pressing member 23 has a vertical plate 23a along the side end surface of the scaffolding plate and a horizontal plate extending horizontally from the upper end of the vertical plate 23a and along the upper end surface of the scaffolding plate. The length (height) L1 of the vertical plate 23a is set to be slightly shorter than the thickness of the scaffold plate, and the overhang length L2 of the horizontal plate 23b is the thickness of the plate 23b. It is set slightly shorter than the thickness of other different scaffolding plates.

また、前記押圧部材２３の角部には、縦板２３ａから横板２３ｂに渡って、軸部材２２が挿通される長孔２３ｃが形成されており、図１７（ａ）、（ｂ）に示すように、ナット２４を外すことなく、押圧部材２３を同図（ａ）に矢印で示す方向に回転させることで、軸部材２２の挿通位置を変更することができ、厚みの異なる他の足場板を使用する場合は、縦板２３ａを足場板の上面に対応する部分に、横板２３ｂを足場板の側端面に対応する部分に入れ替えた状態で押圧部材２３を使用することができるようになっている。   In addition, a long hole 23c through which the shaft member 22 is inserted is formed at the corner of the pressing member 23 from the vertical plate 23a to the horizontal plate 23b, as shown in FIGS. 17 (a) and 17 (b). In this way, the insertion position of the shaft member 22 can be changed by rotating the pressing member 23 in the direction indicated by the arrow in FIG. , The pressing member 23 can be used in a state in which the vertical plate 23a is replaced with the portion corresponding to the upper surface of the scaffolding plate and the horizontal plate 23b is replaced with the portion corresponding to the side end surface of the scaffolding plate. ing.

以上のように構成された金具２を用いて単管パイプＰの上に掛け渡した最端位置の足場板の外側縁部を単管パイプＰに固定する足場板の固定方法について、図１８〜図２１を参照しながら説明する。   About the fixing method of the scaffold board which fixes the outer side edge part of the scaffold board of the extreme end position spanned on the single pipe P using the metal fitting 2 comprised as mentioned above to the single pipe P FIG. This will be described with reference to FIG.

まず、図１８（ａ）〜（ｃ）に示すように、固定済みの足場板ＳＰに一方の側縁を当接させるように最後の足場板ＳＰを単管パイプＰの上に掛け渡した後、図１９（ａ）〜（ｃ）に示すように、金具２のナット２４を軸部材１２の上端側に移動させ、押圧部材２３の横板２３ｂを足場板ＳＰの上側に位置させた状態で、２個の金具２を足場板ＳＰの他方の側縁に沿わせてスライドさせることによって、それぞれの係合部材１１を足場板ＳＰの長手方向の両端側に位置する２本の単管パイプＰにそれぞれ係合させる。   First, as shown in FIGS. 18A to 18C, after the last scaffold plate SP is placed over the single pipe P so that one side edge is brought into contact with the fixed scaffold plate SP. 19 (a) to 19 (c), the nut 24 of the metal fitting 2 is moved to the upper end side of the shaft member 12, and the horizontal plate 23b of the pressing member 23 is positioned above the scaffold plate SP. By sliding the two metal fittings 2 along the other side edge of the scaffolding plate SP, the two single-pipe pipes P positioned at both ends in the longitudinal direction of the scaffolding plate SP. Are engaged with each other.

このとき、金具１と同様に、単管パイプＰによって係止ユニット１４の係止爪１５が係止位置から非係止位置側に押し下げられながら、係合部材１１の半円部１１ａが単管パイプＰに係合し、一旦係合すると、係止爪１５の一端側がダブルトーションばね１６の付勢力によって元の係止位置に押し上げられ、係止爪１５によって金具２が単管パイプＰに係止されるので、金具２が単管パイプＰから容易に脱落することがない。   At this time, as with the metal fitting 1, the semi-circular portion 11a of the engaging member 11 is moved to the single tube while the locking claw 15 of the locking unit 14 is pushed down from the locking position to the non-locking position side by the single pipe P. Once engaged with the pipe P and once engaged, one end of the locking claw 15 is pushed up to the original locking position by the urging force of the double torsion spring 16, and the metal fitting 2 is engaged with the single pipe P by the locking claw 15. Since it stops, the metal fitting 2 does not fall off from the single pipe P easily.

続いて、図２０（ａ）〜（ｃ）に示すように、電動ドライバーＥＤ等の工具を用いてナット２４を回転操作することによって締め込むと、図２１（ａ）〜（ｃ）に示すように、金具２の押圧部材２３（横板２３ｂ）によって最端位置の足場板ＳＰの外側縁部が単管パイプＰに押圧され、金具２を介して最端位置の足場板ＳＰが単管パイプＰに固定される。   Subsequently, as shown in FIGS. 20A to 20C, when the nut 24 is tightened by rotating the tool 24 using a tool such as an electric screwdriver ED, as shown in FIGS. 21A to 21C. Further, the outer edge portion of the endmost scaffold plate SP is pressed against the single pipe P by the pressing member 23 (horizontal plate 23b) of the bracket 2, and the endmost scaffold plate SP is connected to the single pipe through the bracket 2. Fixed to P.

以上のように、この金具２は、押圧部材２３を足場板ＳＰの外側縁部における上面角部に沿わせるように、係合部材１１を単管パイプＰに横方向から係合させる際、単管パイプＰの後方側から係合部材１１を前方側に押し出すようにして単管パイプＰに係合させればよく、係合部材１１を単管パイプＰに係合させた状態では、係止爪１５によって係合部材１１が単管パイプＰに係止されるので、押圧部材２３が足場板ＳＰを単管パイプＰに押圧していない状態であっても、金具２が単管パイプＰから脱落することがなく、金具１と同様に、安全、確実かつ簡単に足場板ＳＰを単管パイプＰに固定することができる。   As described above, when the engagement member 11 is engaged with the single pipe P from the lateral direction so that the pressing member 23 is along the upper surface corner of the outer edge of the scaffolding plate SP, the metal fitting 2 is The engaging member 11 may be engaged with the single pipe P by pushing the engaging member 11 forward from the rear side of the pipe pipe P. When the engaging member 11 is engaged with the single pipe P, Since the engaging member 11 is locked to the single pipe P by the claw 15, even if the pressing member 23 is not pressing the scaffold plate SP against the single pipe P, the metal fitting 2 is removed from the single pipe P. The scaffolding plate SP can be fixed to the single pipe P in a safe, reliable and simple manner as with the metal fitting 1 without falling off.

また、この金具２を用いて足場板ＳＰの外側縁部を単管パイプＰに固定するには、係合部材１１を単管パイプＰに係合させた後、ナット２４をねじ込むだけでよいので、作業者は熟練及び労力を必要とせず、簡単に短時間で足場板ＳＰを単管パイプＰに固定することができる。   Further, in order to fix the outer edge portion of the scaffold plate SP to the single pipe P using this metal fitting 2, it is only necessary to screw the nut 24 after engaging the engaging member 11 with the single pipe P. The operator does not need skill and labor, and can easily fix the scaffolding plate SP to the single pipe P in a short time.

また、足場を解体する際は、ナット２４を緩めて押圧部材２３による最端位置の足場板ＳＰの押圧状態を解除した後、係止爪１５の操作片１５ｃを指でもって係止爪１５の一端側を下方側に押し下げて単管パイプＰに対する係止爪１５の係止状態を解除した状態で、係合部材１１を単管パイプＰから離反する方向にスライドさせて単管パイプＰとの係合を解除するだけで、金具２を単管パイプＰから取り外すことができるので、単管パイプＰに対する足場板ＳＰの固定解除作業も簡単に行うことができ、取り外した金具２は他の工事現場で繰り返し使用することができる。   When the scaffold is disassembled, the nut 24 is loosened to release the pressing state of the scaffold plate SP at the extreme end position by the pressing member 23, and then the operating piece 15c of the locking claw 15 is held with a finger. In a state where one end side is pushed down to release the locking claw 15 from the single tube pipe P, the engagement member 11 is slid in a direction away from the single tube P, and Since the metal fitting 2 can be detached from the single pipe P simply by releasing the engagement, the fixing work of the scaffolding plate SP with respect to the single pipe P can be easily performed. Can be used repeatedly on site.

また、この金具２を用いて足場板ＳＰを単管パイプＰに固定した状態では、足場板ＳＰの外側縁部の上面角部に配設された押圧部材２３における横板２３ｂの上に軸部材１２の上端部が突出することになるが、その突出位置は最端位置の足場板ＳＰの外側縁部であるので、軸部材１２の突出部が足場板ＳＰ上を歩行する作業者の障害となることもない。   Further, in a state where the scaffolding plate SP is fixed to the single pipe P using the metal fitting 2, the shaft member is placed on the horizontal plate 23b of the pressing member 23 disposed at the upper surface corner of the outer edge of the scaffolding plate SP. The upper end of 12 projects, but the projecting position is the outer edge of the scaffolding plate SP at the extreme end, so that the projecting part of the shaft member 12 is an obstacle to the worker walking on the scaffolding plate SP. It will never be.

特に、この金具２は、上述したように、ナット２４を外すことなく、軸部材１２の挿通位置を変更することができ、厚みの異なる他の足場板を使用する場合は、縦板２３ａを足場板の上面に対応する部分に、横板２３ｂを足場板の側端面に対応する部分に入れ替えた状態で押圧部材２３を使用することができるようになっているので、厚みの異なる複数種類の足場板に対応することができる。   In particular, as described above, the metal fitting 2 can change the insertion position of the shaft member 12 without removing the nut 24. When using another scaffold plate having a different thickness, the vertical plate 23a is used as the scaffold. Since the pressing member 23 can be used in a state in which the horizontal plate 23b is replaced with a portion corresponding to the side end surface of the scaffolding plate in a portion corresponding to the upper surface of the plate, a plurality of types of scaffolds having different thicknesses Can correspond to a board.
