そして、この回転金具１０は、ボルト（支軸）９より外側の金具部１０Ａの重量がボルト９より内側の金具部１０Ｂよりも重くなるように設定されていて、ボルト９によりこの回転金具を基枠部８に水平姿勢で回転自在に取り付けた時に、その自重により回転して、内側金具部１０Ｂが持ち上がるようになっている。 The rotating metal fitting 10 is set so that the weight of the metal fitting portion 10A outside the bolt (support shaft) 9 is heavier than the metal fitting portion 10B inside the bolt 9, and the bolt 9 is used to base the rotating metal fitting 10A. When the frame portion 8 is rotatably mounted in a horizontal posture, the inner metal portion 10B is lifted by rotating by its own weight.

上記のように構成される各固定具６を組み立てるには、図５に示すように、固定枠７の下端部にある基枠部８を回転金具１０内に挿入して、回転金具１０の両側板１９，１９に設けてあるボルト挿通孔２３，２３と、基枠部８の両基板部８ａ，８ａに設けてあるボルト挿通孔２７，２７とに亙ってボルト（支軸）９を挿通し、その挿通端部にナット２５を螺合して、基枠部８に回転金具１０をボルト９によって回転自在に取り付ける。この状態では、回転金具１０は、外側金具部１０Ａが内側金具部１０Ｂより重いため、水平姿勢に対し内側金具部１０Ｂが持ち上がった傾斜姿勢となる。 In order to assemble each fixture 6 configured as described above, as shown in FIG. 5, the base frame portion 8 at the lower end portion of the fixed frame 7 is inserted into the rotary fitting 10, and both sides of the rotary fixture 10 are inserted. Bolts (support shafts) 9 are inserted through the bolt insertion holes 23 and 23 provided in the plates 19 and 19 and the bolt insertion holes 27 and 27 provided in both the substrate portions 8a and 8a of the base frame portion 8. Then, the nut 25 is screwed into the insertion end portion, and the rotating metal fitting 10 is rotatably attached to the base frame portion 8 by the bolt 9. In this state, the rotating metal fitting 10 has an inclined posture in which the inner metal fitting portion 10B is lifted with respect to the horizontal posture because the outer metal fitting portion 10A is heavier than the inner metal fitting portion 10B.

次に、ネジロッド１１のロッド部１１ｂをナット部材１２から基枠部８内に挿通して、その挿通端部よりコイルバネ１３を嵌挿し、このコイルバネ１３の一端部を基枠部８の開口部１７に臨むナット部材１２の内端面に当接すると共に、コイルバネ１３を圧縮した状態でその他端部を、ロッド部１１ｂの中間部に挿着した止めピン２６で止着した後、このロッド部１１ｂを基枠部８内にある立上片１６のガイド孔１８に挿通し、そして持ち上がっている内側金具部１０Ｂを上から押し下げた状態でロッド部１１ｂの挿通端部を、回転金具１０内に設けてある載置部２４上に載置する。 Next, the rod portion 11 b of the screw rod 11 is inserted into the base frame portion 8 from the nut member 12, and the coil spring 13 is fitted and inserted from the insertion end portion, and one end portion of the coil spring 13 is connected to the opening portion 17 of the base frame portion 8. The other end portion of the nut member 12 that contacts the inner end surface of the nut member 12 facing the rim is fastened with a stop pin 26 that is inserted into the intermediate portion of the rod portion 11b while the coil spring 13 is compressed. An insertion end portion of the rod portion 11b is provided in the rotating metal fitting 10 while being inserted through the guide hole 18 of the rising piece 16 in the frame portion 8 and pushing down the raised inner metal fitting portion 10B from above. Place on the placement unit 24.

こうして基枠部８側のナット部材１２から立上片１６のガイド孔１８に挿通させたロッド部１１ｂの先端部を回転金具１０側の載置部２４上に載置することによって、回転金具１０は、重量の軽い内側金具部１０Ｂがネジロッド１１のロッド部１１ｂ先端部で上から押し付けられて、内側金具部１０Ｂと外側金具部１０Ａとの均衡状態が保たれる（図２の(a) 参照）。これによって、固定具６の組み立てが完了する。 In this way, by placing the tip end portion of the rod portion 11b inserted from the nut member 12 on the base frame portion 8 side into the guide hole 18 of the rising piece 16 on the placement portion 24 on the rotation fitting 10 side, the rotating fitting 10 is provided. The inner metal part 10B, which is light in weight, is pressed from above at the tip of the rod part 11b of the screw rod 11, so that the balanced state between the inner metal part 10B and the outer metal part 10A is maintained (see FIG. 2A). ). Thereby, the assembly of the fixture 6 is completed.

上記のようにして固定具６を組み立てた後、固定具６の固定枠７を幅木本体５の外面側両端部に固定する。即ち、固定枠７の取付板部１５，１５を、幅木本体５の外面側にある上下フランジ５ｄ，５ｄの所定箇所に当て付けて、リベットＲ（図２〜図４参照）により固定する。こうして固定具６を幅木本体５に取付け固定した幅木４を完成した状態を図２の(a) に示す。 After assembling the fixing tool 6 as described above, the fixing frame 7 of the fixing tool 6 is fixed to both end portions on the outer surface side of the baseboard body 5. That is, the attachment plate portions 15 and 15 of the fixed frame 7 are applied to predetermined positions of the upper and lower flanges 5d and 5d on the outer surface side of the skirting board main body 5 and fixed by the rivet R (see FIGS. 2 to 4). FIG. 2 (a) shows a state in which the skirting board 4 in which the fixing tool 6 is attached and fixed to the skirting board main body 5 is completed.

上記のように幅木本体５に固定具６を取り付けた幅木４を足場板１に設置する手順を以下に説明する。 The procedure for installing the skirting board 4 with the fixture 6 attached to the skirting board body 5 as described above on the scaffolding board 1 will be described below.

先ず、図２の(b) に示すように、幅木本体５を足場板１の側縁部上に載せて、この足場板１の側面部１ｂを幅木本体５下面と固定枠７との間に引き込んだ状態とする。この時、回転金具１０は、軽い方の内側金具部１０Ｂがネジロッド１１のロッド部１１ｂ先端部で上から押えられて均衡状態を保し、水平姿勢にある。尚、図２の(b) において、実線で示す足場板１の側面部１ｂは、その高さが低い（例えば４０ｍｍ）の足場板１を示し、仮想線で示す側面部１ｂは、高さが高い（例えば５０ｍｍ）足場板１示すもので、この固定具６は、側面部１ｂの高さの高低異なる足場板１にも使用可能となる。 First, as shown in FIG. 2 (b), the baseboard body 5 is placed on the side edge of the scaffold board 1, and the side face 1 b of the scaffold board 1 is placed between the lower surface of the baseboard body 5 and the fixed frame 7. It is in a state of being drawn in between. At this time, the rotating metal fitting 10 is in a horizontal posture with the lighter inner metal fitting portion 10B being pressed from above at the tip of the rod portion 11b of the screw rod 11 to maintain an equilibrium state. In FIG. 2 (b), the side portion 1b of the scaffold plate 1 indicated by a solid line indicates the scaffold plate 1 having a low height (for example, 40 mm), and the side portion 1b indicated by a virtual line has a height of As shown in a high (for example, 50 mm) scaffolding plate 1, the fixture 6 can be used for the scaffolding plate 1 having different heights of the side surface portion 1b.

それから、図３の(a) に示すように、蝶ボルトからなるネジロッド１１を、コイルバネ１３の付勢力に抗して手前側へ引くと、ロッド部１１ｂの先端部が回転金具１０の内側金具部１０Ｂの載置部２４から離れて、ロッド部１１ｂと内側金具部１０Ｂとの縁が切れ、そうすると外側金具部１０Ａが内側金具部１０Ｂよりも重いため、外側金具部１０Ａは内側金具部１０Ｂに打ち勝ってその自重により、回転金具１０は、この図３の(a) のように外側金具部１０Ａが下がり、内側金具部１０Ｂが持ち上がった状態に回転変位する。 Then, as shown in FIG. 3 (a), when the screw rod 11 made of a butterfly bolt is pulled to the near side against the urging force of the coil spring 13, the tip of the rod portion 11b becomes the inner fitting portion of the rotating fitting 10. The edge of the rod part 11b and the inner metal part 10B is cut away from the mounting part 24 of 10B, and the outer metal part 10A is heavier than the inner metal part 10B, so that the outer metal part 10A overcomes the inner metal part 10B. Due to its own weight, the rotating metal fitting 10 is rotationally displaced so that the outer metal fitting part 10A is lowered and the inner metal fitting part 10B is lifted as shown in FIG.

こうして内側金具部１０Ｂが持ち上がった状態に回転金具１０が回転変位した状態で、ネジロッド１１のネジ部１１ａを基枠部８のナット部材１２に螺合して数回閉め込んで、図３の(a) に示すようにロッド部１１ｂの先端を、外側金具部１０Ａ側の底板２０内面を押接することにより、図３の(b) に示すように回転金具１０が更に回転して、内側金具部１０Ｂの足場板押え２２が足場板１の側面部１ｂに押し付けられ、それによりこの足場板押え２２と固定枠７のチャンネル部１４（正確には、その両側板部１４ａ，１４ａの先端縁１４ｃ，１４ｃ）とで足場板１の側面部１ｂが挟持されて固定枠７が足場板１に固定され、幅木４が幅木本体５が足場板１の側縁部上に載置した状態に固定される。 In the state where the rotary metal fitting 10 is rotated and displaced while the inner metal fitting portion 10B is lifted up, the screw portion 11a of the screw rod 11 is screwed into the nut member 12 of the base frame portion 8 and closed several times. As shown in FIG. 3B, the end of the rod part 11b is pressed against the inner surface of the bottom plate 20 on the outer metal part 10A side, whereby the rotary metal part 10 is further rotated as shown in FIG. The scaffolding plate retainer 22 of 10B is pressed against the side surface portion 1b of the scaffolding plate 1, whereby the scaffolding plate retainer 22 and the channel portion 14 of the fixed frame 7 (precisely, the leading edge 14c of the both side plate portions 14a, 14a, 14c), the side part 1b of the scaffolding board 1 is clamped, the fixed frame 7 is fixed to the scaffolding board 1, and the baseboard 4 is fixed in a state where the baseboard body 5 is placed on the side edge of the scaffolding board 1. Is done.

要するに、幅木４を足場板１に設置する時は、幅木本体５を足場板１の側縁部上に載せて、足場板１の側面部１ｂを幅木本体５下面と固定枠７との間に引き込んだ状態で、ネジロッド１１を手前側へ引いて、回転金具１０を自重で回転させて内側金具部１０Ｂを持ち上げた状態から、ネジロッド１１のネジ部１１ａをナット部材１２に螺合させて数回ねじ込めばよい。 In short, when the skirting board 4 is installed on the scaffolding board 1, the skirting board main body 5 is placed on the side edge of the scaffolding board 1, and the side part 1 b of the scaffolding board 1 is placed on the lower surface of the skirting board main body 5 and the fixed frame 7. In a state where the screw rod 11 is pulled to the near side, the rotating metal fitting 10 is rotated by its own weight to lift the inner metal fitting portion 10B, and then the screw portion 11a of the screw rod 11 is screwed to the nut member 12. Can be screwed in several times.

また、幅木４を足場板１から取り外す時は、図４に示すように、ネジロッド１１のネジ部１１ａを緩めてナット部材１２から引き出した後、回転金具１０の外向き延設片２１を持ち上げて回転金具１０を水平姿勢まで回転させるだけでよい。取外し後は、ネジロッド１１のロッド部１１ｂ先端部を内側金具部１０Ｂの載置部２４に載置すれば、図２の(a) に示す元の状態となる。 Further, when removing the skirting board 4 from the scaffolding plate 1, as shown in FIG. 4, the screw part 11 a of the screw rod 11 is loosened and pulled out from the nut member 12, and then the outwardly extending piece 21 of the rotary fitting 10 is lifted. Thus, it is only necessary to rotate the rotating metal fitting 10 to the horizontal posture. After removal, if the tip of the rod portion 11b of the screw rod 11 is placed on the placement portion 24 of the inner metal fitting 10B, the original state shown in FIG.

この幅木４の固定具６では、上記のように回転金具１０を自重により回転させて内側金具部１０Ｂを持ち上げ、この持ち上げた内側金具部１０Ｂの足場板押え２２を足場板１の側面部１ｂに押し付けて、固定枠７を足場板１に固定する構造であって、幅木本体５下面から下方に十分な空間部がとれるから、板厚の異なる複数種類の足場板１にも適用可能となる。 In the fixing member 6 of the skirting board 4, as described above, the rotating metal fitting 10 is rotated by its own weight to lift the inner metal fitting portion 10B, and the scaffolding plate presser 22 of the lifted inner metal fitting portion 10B is used as the side surface portion 1b of the scaffolding plate 1. And the fixing frame 7 is fixed to the scaffolding plate 1, and a sufficient space can be taken downward from the lower surface of the baseboard body 5, so that it can be applied to a plurality of types of scaffolding plates 1 having different thicknesses. Become.

また、この固定具６においては、ネジロッド１１が、蝶形頭部１１ｃに隣接するネジ部１１ａと、ネジ部１１ａから同軸一体に延びるロッド部１１ｂとを有する蝶ボルトからなるため、ネジロッド１１の押し引き及び回転操作を蝶形頭部１１ｃで容易に行うことができる。 Further, in this fixture 6, the screw rod 11 is composed of a butterfly bolt having a screw portion 11a adjacent to the butterfly head portion 11c and a rod portion 11b extending coaxially from the screw portion 11a. Pulling and rotating operations can be easily performed with the butterfly head 11c.

またこの固定具６では、基枠部８の外端部側にナット部材１２を設け、このナット部材１２に対向する内端部側に、ナット部材１２に挿通したネジロッド１１のロッド部１１ｂをロッド長手方向スライド自在に支持案内するガイド部１８を設けているため、ネジロッド１１を常に水平姿勢に保持でき、ロッド部１１ｂの先端部によって回転金具１０の内側金具部１０Ｂを的確に支持することができる。 Further, in the fixture 6, a nut member 12 is provided on the outer end side of the base frame portion 8, and the rod portion 11 b of the screw rod 11 inserted through the nut member 12 is connected to the inner end side facing the nut member 12. Since the guide portion 18 that is supported and guided so as to be slidable in the longitudinal direction is provided, the screw rod 11 can always be held in a horizontal posture, and the inner metal portion 10B of the rotating metal fitting 10 can be accurately supported by the tip portion of the rod portion 11b. .

また、回転金具１０の内側金具部１０Ｂに、ナット部材１２に挿通したロッド部１１ｂの先端部側を載置する載置部２４を設けることにより、回転金具１０の内側金具部１０Ｂを所定姿勢に確実に支持することができる。 In addition, by providing a mounting portion 24 for mounting the tip end side of the rod portion 11b inserted through the nut member 12 in the inner metal fitting portion 10B of the rotary fitting 10, the inner metal fitting portion 10B of the rotating metal fitting 10 is brought into a predetermined posture. It can be reliably supported.

以上説明した実施形態では、２つの固定具６を幅木本体５の両端部に装備しているが、幅木本体５の長さが長い場合は３つ以上の固定具６を装備してもよく、また幅木本体５の長さが短い場合には、固定具６は幅木本体５の中央部に１つだけ装備してもよい。 In the embodiment described above, the two fixing tools 6 are provided at both ends of the baseboard body 5, but when the baseboard body 5 is long, three or more fixing tools 6 may be provided. In addition, when the length of the skirting board main body 5 is short, only one fixing tool 6 may be provided at the center of the skirting board main body 5.

以上説明した実施形態では、回転金具１０は、ボルト（支軸）９より外側の金具部１０Ａの重量がボルト９より内側の金具部１０Ｂよりも重くなるように設定され、ボルト９によりこの回転金具を基枠部８に水平姿勢で回転自在に取り付けた時に、その自重により回転して、内側金具部１０Ｂが持ち上がるようにした自重回転方式を採用したものであるが、図９以下に示すように、バネ付勢手段によって回転金具１０を回転させるバネ付勢回転方式を採用してもよい。なお、図９以下の説明において、前記実施形態と同じ構成要素については、同一符号を付してその説明を省略することもある。 In the embodiment described above, the rotating metal fitting 10 is set so that the weight of the metal fitting part 10A outside the bolt (support shaft) 9 is heavier than the metal fitting part 10B inside the bolt 9, and the rotating metal fitting 10 Is mounted on the base frame portion 8 in a horizontal posture so as to rotate freely, and is rotated by its own weight so that the inner metal fitting portion 10B is lifted. However, as shown in FIG. A spring biasing rotation method in which the rotating metal fitting 10 is rotated by a spring biasing means may be employed. In the description of FIG. 9 and subsequent figures, the same components as those in the above embodiment may be denoted by the same reference numerals and the description thereof may be omitted.

即ち、図９に示すように、固定枠７と回転金具１０とにわたってねじりバネからなる回転金具回転付勢バネ２８を介在させて、該回転付勢バネ２８の付勢力によって、回転金具１０は、ボルト（支軸）９より外側の金具部１０Ａがその支軸９より下向きに下がり、ボルト９より内側の金具部１０Ｂが持ち上がるようになっている。 That is, as shown in FIG. 9, a rotating bracket rotating biasing spring 28 made of a torsion spring is interposed between the fixed frame 7 and the rotating bracket 10, and the rotating bracket 10 is rotated by the biasing force of the rotating biasing spring 28. A metal part 10A outside the bolt (support shaft) 9 is lowered downward from the support shaft 9, and a metal part 10B inside the bolt 9 is lifted.

この回転付勢バネ２８は、図１２に示すように、ねじりバネからなり、ねじり巻き部２８ｂとその一端部両側部の二股状の回転側端部２８ａ，２８ａとその他端部中央部の固定側端部２８ｃとからなり、ねじり巻き部２８ｂを支軸９に巻き付け、その一端部両側部の二股状の回転側端部２８ａ，２８ａを回転金具１０に取り付ける。詳細には、図７の（ｃ）に示すように、回転金具１０の底板２０の両側端部に２個の取付孔２９，２９を穿ち、この取付孔２９，２９に前記二股状の回転側端部２８ａ，２８ａを挿入して取り付ける。又、その他端部中央部の固定側端部２８ｃを固定枠７に取り付ける。詳細には、図６の（ｂ）に示すように、固定枠７の基枠部８の背板部１４の中央部に取付孔３０を穿ち、この取付孔３０に前記固定側端部２８ｃを挿入して取り付けるものである。 As shown in FIG. 12, the rotation urging spring 28 comprises a torsion spring, a torsion winding portion 28b, bifurcated rotation end portions 28a and 28a on both sides of one end portion thereof, and a fixed side at the center portion of the other end portion.

The edge of the rod part 11b and the inner metal part 10B is cut away from the mounting part 24 of 10B, and then the outer metal part 10A is lowered around the support shaft 9 by the urging force of the rotation urging spring 28, and the inner metal part is lowered. The part 10B is rotationally displaced in a lifted state.

こうして内側金具部１０Ｂが持ち上がった状態に回転金具１０が回転変位した状態で、ネジロッド１１のネジ部１１ａを基枠部８のナット部材１２に螺合して数回閉め込んで、図１０の(a) に示すようにロッド部１１ｂの先端を、外側金具部１０Ａ側の底板２０内面を押接することにより、図１０の(b) に示すように回転金具１０が更に回転して、内側金具部１０Ｂの足場板押え２２が足場板１の側面部１ｂに押し付けられ、それによりこの足場板押え２２と固定枠７のチャンネル部１４とで足場板１の側面部１ｂが挟持されて固定枠７が足場板１に固定され、幅木４が幅木本体５が足場板１の側縁部上に載置した状態に固定される。 In a state where the rotary metal fitting 10 is rotated and displaced while the inner metal fitting portion 10B is lifted up, the screw portion 11a of the screw rod 11 is screwed into the nut member 12 of the base frame portion 8 and closed several times. As shown in FIG. 10 (a), when the tip of the rod portion 11b is pressed against the inner surface of the bottom plate 20 on the side of the outer metal fitting 10A, the rotary metal fitting 10 further rotates as shown in FIG. The scaffolding plate retainer 22 of 10B is pressed against the side surface portion 1b of the scaffolding plate 1, whereby the scaffolding plate retainer 22 and the channel portion 14 of the fixed frame 7 sandwich the side surface portion 1b of the scaffolding plate 1 so that the fixed frame 7 is fixed. The base plate 4 is fixed to the scaffold board 1 and the base board body 5 is fixed to a state where the base board body 5 is placed on the side edge of the scaffold board 1.

要するに、幅木４を足場板１に設置する時は、幅木本体５を足場板１の側縁部上に載せて、足場板１の側面部１ｂを幅木本体５下面と固定枠７との間に引き込んだ状態で、ネジロッド１１を手前側へ引くことによって、回転金具１０を回転付勢バネ２８の付勢力によって回転させて内側金具部１０Ｂを持ち上げた状態から、ネジロッド１１のネジ部１１ａをナット部材１２に螺合させて数回ねじ込めばよい。 In short, when the skirting board 4 is installed on the scaffolding board 1, the skirting board main body 5 is placed on the side edge of the scaffolding board 1, and the side part 1 b of the scaffolding board 1 is placed on the lower surface of the skirting board main body 5 and the fixed frame 7. In a state where the screw rod 11 is pulled in between, the rotating metal fitting 10 is rotated by the urging force of the rotation urging spring 28 to lift the inner metal fitting portion 10B from the state where the inner metal fitting portion 10B is lifted. May be screwed into the nut member 12 and screwed in several times.

また、幅木４を足場板１から取り外す時は、図１１に示すように、ネジロッド１１のネジ部１１ａを緩めてナット部材１２から引き出した後、回転付勢バネ２８の付勢力に抗して回転金具１０の外向き延設片２１を持ち上げて回転金具１０を水平姿勢まで回転させるだけでよい。取外し後は、ネジロッド１１のロッド部１１ｂ先端部を内側金具部１０Ｂの載置部２４に載置すれば、図９の(a) に示す元の状態となる。 Further, when removing the skirting board 4 from the scaffolding plate 1, as shown in FIG. 11, after loosening the screw portion 11 a of the screw rod 11 and pulling it out from the nut member 12, the urging force of the rotary biasing spring 28 is resisted. It is only necessary to lift the outwardly extending piece 21 of the rotating bracket 10 and rotate the rotating bracket 10 to a horizontal posture. After removal, if the tip of the rod portion 11b of the screw rod 11 is placed on the placement portion 24 of the inner metal fitting 10B, the original state shown in FIG.

この回転付勢バネ２８によるバネ付勢回転方式だけで、回転金具１０を回転させるようにしてもよいが、前記自重回転方式による回転力を補うために、バネ付勢回転方式を併用してもよい。即ち、回転金具１０の外側金具部１０Ａを内側金具部１０Ｂよりも重く、両者の重量差によって回転金具１０に回転力を付与するだけでは、未だ回転力が不足している場合に、このバネ付勢回転方式を併用することによって回転金具１０の回転力を円滑に取り出すことができ、その作動状態を良好に維持することができる。 The rotating metal fitting 10 may be rotated only by the spring biased rotation method by the rotation biasing spring 28. However, in order to supplement the rotational force by the self-weight rotation method, the spring biased rotation method may be used in combination. Good. That is, when the outer metal part 10A of the rotary metal fitting 10 is heavier than the inner metal fitting part 10B and the rotational force is still insufficient due to the difference in weight between the two metal parts, the spring attachment is provided. By using the force rotation method in combination, the rotational force of the rotating metal fitting 10 can be taken out smoothly, and the operating state can be maintained well.
