And there is always a danger of accidents. Therefore, baseboards are attached on the side edges of the scaffolding board.

従来の足場板用幅木として、例えば、下記特許文献1に記載されたものがある。これは、幅木本体の外面側に、複数のスライドロック金具が、夫々ロックボルトの回動操作によって幅木本体に対し上下にスライドするように取り付けられ、各スライドロック金具は、幅木本体よりも下方に突出する下部に幅木本体の下面と対向するロック片を備え、このロック片と幅木本体の下面との間に足場板の側縁部を嵌め込んだ状態で、スライドロック金具が上方へスライドするようにロックボルトを締め付けることによって、幅木本体が垂直姿勢に固定されるようになっている。   As a conventional scaffold board skirting board, there exists what was described in the following patent document 1, for example. This is because a plurality of slide lock fittings are mounted on the outer surface side of the skirting board body so that each slide lock fitting slides up and down with respect to the skirting board body by rotating the lock bolt. The lower part of the base plate has a lock piece that faces the lower surface of the skirting board body, and the slide lock bracket is fitted with the side edge of the scaffolding plate between the lock piece and the lower surface of the skirting board body. By tightening the lock bolt so as to slide upward, the skirting board main body is fixed in a vertical posture.

The lever 8 is gripped by a grip 8o at its upper end and rotated downward to slide the slide plate 9a of the gripping metal 9 through the leaf spring 11 to the lower limit position of the slide range. From the state where the space between the hook portion 10 and the tip portion 10o is widened to the maximum, the side bent portion 1b of the scaffold plate 1 is fitted into this space portion, and the state as shown in FIG.

上記のようにして幅木本体5の下面と掴み金具9下部側のフック部10との間に足場板1の側面折り曲げ部1bを嵌め込んだ状態とした後、図6の(c) に示すように操作レバー8を上向きに回転させることにより、板バネ11を介して掴み金具9のスライド板9aを上方へスライドさせて、足場板1の側面折り曲げ部1bをフック部10で掴み、そして更に操作レバー8を回転させて起立状態にすると、(d) に示すようにスライド板9aが板バネ11を介しスライド範囲の上限位置までスライドして、フック部10が足場板1の側面折り曲げ部1bを掴んでフック部10の底板部9bが側面折り曲げ部1bの下面1boに当接すると共に、フック部10の先端部である、フック部10の上端部10oが足場板1の天板部1a下面に当接した状態にロックされる。   After the side bent portion 1b of the scaffolding plate 1 is fitted between the lower surface of the skirting board main body 5 and the hook portion 10 on the lower side of the gripping metal 9 as described above, it is shown in FIG. Thus, by rotating the operating lever 8 upward, the slide plate 9a of the gripping bracket 9 is slid upward through the leaf spring 11, the side bent portion 1b of the scaffold plate 1 is gripped by the hook portion 10, and further When the operation lever 8 is rotated to stand up, the slide plate 9a is slid to the upper limit position of the slide range via the leaf spring 11 as shown in (d), and the hook portion 10 is bent to the side bent portion 1b of the scaffold plate 1. The bottom plate portion 9b of the hook portion 10 is in contact with the lower surface 1bo of the side bent portion 1b, and the upper end portion 10o of the hook portion 10, which is the tip portion of the hook portion 10, is on the lower surface of the top plate portion 1a of the scaffold plate 1. In contact It is locked.

このように操作レバー8を起立状態にすることによって、掴み金具9のフック部10が足場板1の側面折り曲げ部1bを掴んだ位置にロックされるが、この場合、仮にフック部10の上端部10oが足場板1の天板部1a下面に当接せず、そのフック部10が足場板1の側面折り曲げ部1bを掴んだだけの状態でロックされるものとすれば、幅木本体5に足場板1の内側から大きな横荷重がかかった時に、側面折り曲げ部1bには掴み金具9のスライド板9aにより大きな曲げモーメントが作用して変形するおそれがある。しかし、このワンタッチロック金具6にあっては、フック部10が足場板1の側面折り曲げ部1bを掴むと同時に、フック部10の先端部10oが足場板1の天板部1a下面で支持されるため、側面折り曲げ部1bが大きな曲げを受けず、その変形が防止される。   Thus, by making the operating lever 8 stand up, the hook portion 10 of the gripping metal 9 is locked at the position where the side bent portion 1b of the scaffold plate 1 is gripped. In this case, the upper end portion of the hook portion 10 is temporarily assumed. Assuming that 10o is not in contact with the lower surface of the top plate portion 1a of the scaffold plate 1 and that the hook portion 10 is locked in a state where the side plate bent portion 1b of the scaffold plate 1 is only gripped, When a large lateral load is applied from the inside of the scaffold plate 1, there is a possibility that a large bending moment acts on the side bent portion 1 b due to the slide plate 9 a of the gripping metal 9 and deforms. However, in this one-touch lock fitting 6, the hook portion 10 grips the side bent portion 1b of the scaffold plate 1, and at the same time, the tip portion 10o of the hook portion 10 is supported by the lower surface of the top plate portion 1a of the scaffold plate 1. For this reason, the side bent portion 1b is not subjected to large bending, and its deformation is prevented.

また、この場合、掴み金具9のフック部10が足場板1の側面折り曲げ部1bを掴んでフック部10の底板部9bが側面折り曲げ部1bの下面1boに当接すると共に、フック部10の先端部10oが足場板1の天板部1aの下面に当接するようになっているから、フック部10が側面折り曲げ部1bを的確に掴持することができて、フック部10と足場板1の天板部1a及び側面折り曲げ部1bとが一体化し、幅木本体5を足場板1に対し安定良く強固に固定することができる。   In this case, the hook portion 10 of the gripping metal 9 grasps the side surface bent portion 1b of the scaffold plate 1 so that the bottom plate portion 9b of the hook portion 10 contacts the lower surface 1bo of the side surface bent portion 1b, and the tip portion of the hook portion 10 Since 10o abuts on the lower surface of the top plate portion 1a of the scaffold plate 1, the hook portion 10 can accurately hold the side bent portion 1b, and the top of the hook portion 10 and the scaffold plate 1 can be secured. The plate portion 1a and the side bent portion 1b are integrated, and the baseboard body 5 can be stably and firmly fixed to the scaffold plate 1.

尚、上記のようにフック部10の底板部9bが側面折り曲げ部1bの下面1boに当接すると共にフック部10の先端部10oが足場板1の天板部1aの下面に当接するように構成するのが好ましいが、この掴み金具9で最も重要なことは、フック部10が足場板1の側面折り曲げ部1bを掴んだ状態でフック部10の先端部10oが足場板1の天板部1aの下面に当接することであるから、フック部10の底板部9bが、側面折り曲げ部1bの下面1boに当接せず、その下面1boからある程度離間していてもよい。   As described above, the bottom plate portion 9b of the hook portion 10 is in contact with the lower surface 1bo of the side bent portion 1b, and the tip portion 10o of the hook portion 10 is in contact with the lower surface of the top plate portion 1a of the scaffold plate 1. However, the most important thing in this gripping metal 9 is that the tip portion 10o of the hook portion 10 of the top plate portion 1a of the scaffold plate 1 is in a state where the hook portion 10 grips the side bent portion 1b of the scaffold plate 1. Since it is in contact with the lower surface, the bottom plate portion 9b of the hook portion 10 may not be in contact with the lower surface 1bo of the side bent portion 1b and may be spaced apart from the lower surface 1bo to some extent.

幅木本体5を足場板1から取り外すには、図6の(a) 〜(d) によって説明した取付手順を逆に行えばよい。即ち、(d) に示すように起立姿勢にある操作レバー8を、把手8oを掴んで(c) に示すように下方へ回転させると、操作レバー8と連動する板バネ11によりスライド板9aが下方へスライドし、この操作レバー8を更に下向きに回転させることにより、(b) に示すようにスライド板9aがスライド範囲の下限位置までスライドして、幅木本体5の下面とフック部10の先端部10oとの間隔が最大に広がるから、この状態で掴み金具9を足場板1の側面折り曲げ部1bから抜き取って、幅木本体5を足場板1から取り外すことができる。   In order to remove the skirting board main body 5 from the scaffold board 1, the attachment procedure described with reference to FIGS. That is, when the operating lever 8 in the standing posture as shown in (d) is gripped by the handle 8o and rotated downward as shown in (c), the slide plate 9a is moved by the leaf spring 11 interlocked with the operating lever 8. By sliding downward and rotating the operation lever 8 further downward, the slide plate 9a slides to the lower limit position of the slide range as shown in FIG. Since the distance from the distal end portion 10o is maximized, the base metal body 5 can be detached from the scaffold board 1 by pulling the gripping metal 9 from the side bent portion 1b of the scaffold board 1 in this state.

以上説明したように、この足場板用幅木4は、幅木本体5の外面側に複数のワンタッチロック金具6を設けたもので、幅木4を足場板16の側縁部1a上に取り付ける時には、操作レバー8を下向きに回転させることにより、板バネ11を介して掴み金具9のスライド板9aをスライド範囲の下限位置までスライドさせて、幅木本体5下面とフック部10の先端部10oとの間隔を最大に広げた状態から、足場板1の側面折り曲げ部1bを嵌め込んだ後、操作レバー8を上向きに回転させて起立状態にすれば、スライド板9aが上限位置までスライドして、掴み金具9のフック部10が足場板1の側面折り曲げ部1bを掴み、フック部10の先端部10oが足場板1の天板部1a下面に当接した状態にロックされ、また幅木4を足場板1から取り外す時は、起立姿勢にある操作レバー8を下方へ回転させるだけで掴み金具9がロック解除されるから、足場板1への取付け及び足場板1からの取外しをワンタッチで簡単に行うことができる。   As described above, the scaffold board baseboard 4 is provided with a plurality of one-touch lock fittings 6 on the outer surface side of the baseboard body 5, and the baseboard 4 is attached on the side edge 1 a of the scaffold board 16. Sometimes, by rotating the operation lever 8 downward, the slide plate 9a of the gripping metal piece 9 is slid to the lower limit position of the slide range via the leaf spring 11, and the lower surface of the baseboard body 5 and the tip portion 10o of the hook portion 10 are moved. From the state where the distance between the slide plate 9a and the side plate 1b is set to the maximum, after the side bent portion 1b of the scaffolding plate 1 is fitted, the operation lever 8 is rotated upward to bring the slide plate 9a to the upper limit position. The hook portion 10 of the gripping metal 9 grips the side bent portion 1b of the scaffold plate 1, the tip portion 10o of the hook portion 10 is locked in contact with the lower surface of the top plate portion 1a of the scaffold plate 1, and the baseboard 4 From scaffolding board 1 When removing, the handle 9 is unlocked simply by rotating the operating lever 8 in the standing posture downward, so that the attachment to the scaffold plate 1 and the removal from the scaffold plate 1 can be easily performed with one touch. it can.

また、この足場板用幅木4のワンタッチロック金具6では、操作レバー8が起立して掴み金具9がロック位置にある時、操作レバー8の上端部に形成された把手8oが幅木本体5の上方に突出するようになっているから、操作レバー8の操作が容易となる。尚、この実施形態では、操作レバー8の把手8oが幅木本体5の上端から上方に突出するようになっているが、操作レバー8の把手8oが幅木本体5の外面側から外側方へ突出するようになっていてもよい。何れにしても、操作レバー8の把手8oは、操作レバー8が起立姿勢にある時に、幅木本体5の内部に収納されず、幅木本体5の外側に突出する必要があり、そうすることによって操作レバー8の操作が容易となる。   Further, in the one-touch lock fitting 6 of the scaffold board skirting board 4, when the operation lever 8 stands up and the gripping fitting 9 is in the locked position, the handle 8 o formed at the upper end of the operation lever 8 is the skirting board body 5. Therefore, the operation lever 8 can be easily operated. In this embodiment, the handle 8o of the operation lever 8 protrudes upward from the upper end of the baseboard body 5. However, the handle 8o of the operation lever 8 extends outward from the outer surface side of the baseboard body 5. It may come to protrude. In any case, the handle 8o of the operation lever 8 is not housed inside the skirting board body 5 when the operation lever 8 is in the standing posture, and needs to protrude to the outside of the skirting board body 5. Thus, the operation of the operation lever 8 becomes easy.

また、図6に示すように、幅木本体5が足場板1の天板部1aの側縁部上に載置される時ちは、幅木本体5の下部側フランジ5c下面に突設された凸条部5oが、足場板1の天板部1a上面に形成された凹条部1oに係合するため、幅木本体5は天板部1a上で位置ズレすることがなく、定位置に保持される。   Further, as shown in FIG. 6, when the skirting board body 5 is placed on the side edge of the top plate part 1 a of the scaffolding board 1, the skirting board body 5 protrudes from the lower surface of the lower flange 5 c of the skirting board body 5. Since the raised ridge portion 5o engages with the recessed portion 1o formed on the top surface of the top plate portion 1a of the scaffold plate 1, the baseboard body 5 is not displaced on the top plate portion 1a. Retained.

なお、前記実施形態では、ワンタッチロック金具6を幅木4の長手方向の2カ所に設けるようになっているが、幅木4の全長が短い場合、あるいは、幅木4を足場板1の妻側に設ける場合には、幅木の全長は、例えば50cm程度であり、このように幅木全長の短い場合には幅木長手方向中央部にワンタッチロック金具6を単体設けるだけで足る場合がある。   In the above-described embodiment, the one-touch lock fittings 6 are provided at two positions in the longitudinal direction of the skirting board 4, but when the skirting board 4 is short in length, or the skirting board 4 is used as the wife of the scaffold board 1. When it is provided on the side, the total length of the skirting board is, for example, about 50 cm. When the total length of the skirting board is short as described above, it may be sufficient to provide the one-touch lock fitting 6 alone at the center part in the longitudinal direction of the skirting board. .
