Description

本発明は、囲い枠を有していて折り畳み可能な足場台装置に関する。 The present invention relates to a scaffolding device that has an enclosure and is foldable.

建築工事現場等で使用される足場台装置は、足場板の側部に側枠を立設したもの、さらに足場板の端部に立地のための脚体を設けたものがあり、運搬容易にするために側枠は折り畳み可能になっている。
特許文献１に開示された従来技術は、一対の梯子状の主脚間に天板を架け渡し、前記天板の４隅に主脚に沿って折り畳み可能に取り付けた棒状の手掛かり部材を立設可能とした可搬式作業台において、天板の長さ方向では、立設状態の前記手掛かり部材同士に長手方向用手摺桟を掛け渡し、天板の幅方向では、長手方向用手摺桟に収納可能で、かつ、一端を長手方向用手摺桟に軸着した短手方向用手摺桟を対向する長手方向用手摺桟に掛け渡している（請求項１）。 Scaffolding devices used at construction sites and the like have side frames erected on the sides of the scaffolding board, and further have legs at the ends of the scaffolding board for positioning, and the side frames are foldable to make them easier to transport.
The prior art disclosed in Patent Document 1 is a portable workbench in which a top plate is spanned between a pair of ladder-shaped main legs, and rod-shaped handrail members are foldably attached along the main legs at the four corners of the top plate and can be erected, in which a longitudinal handrail rail is spanned between the upright handrail members in the lengthwise direction of the top plate, and a short-side handrail rail that can be stored in the longitudinal handrail rail and has one end pivotally attached to the longitudinal handrail rail is spanned across the opposing longitudinal handrail rail in the width direction of the top plate (Claim 1).

特開２００７－３２１３５０号公報JP 2007-321350 A

前記従来技術は、短手方向の手摺桟によって、天板の昇降口の位置を作業者に知らせることはできるが、天板の４隅の手掛かり部材は主脚と天板とに対して回動自在に連結されており、手掛かり部材間の長手方向の手摺桟は分割体となっているので、手掛かり部材を主脚に沿って折り畳み可能とするために、長手方向側の側枠として立設したときの剛性を維持することが難い構造になっている。 In the above-mentioned conventional technology, the handrail bars on the short sides can inform the worker of the position of the access point on the tabletop, but the handrail members on the four corners of the tabletop are connected to the main legs and the tabletop so that they can rotate freely, and the handrail bars in the long direction between the handrail members are separate bodies, so that the handrail members can be folded along the main legs, making it difficult to maintain rigidity when erected as side frames on the long sides.

本発明は、このような従来技術の問題点を解決できるようにした足場台装置を提供することを目的とする。
本発明は、側枠の支柱を足場板に対して昇降可能にしかつ屈曲可能にして、側枠を足場板に立設状態から折り畳み、側枠の剛性を維持したまま折り畳めるようにした足場台装置を提供することを目的とする。 An object of the present invention is to provide a scaffolding device that can solve the problems of the conventional technology.
To provide a scaffolding device in which the support pillars of the side frames can be raised and lowered relative to the scaffolding board and can be bent, so that the side frames can be folded from an upright state onto the scaffolding board while maintaining the rigidity of the side frames.

本発明における課題解決のための具体的手段は、両端縁３ａと両側縁３ｂとを有する矩形状の足場板３と、この足場板３の各側縁３ｂに沿って配置された側枠４とを備えており、前記側枠４は一対の支柱５と、この支柱５の上端に連結される側桟部材６とを有し、前記各支柱５の下部は各側縁３ｂの両端部に固定の支持具７に装着されている足場台装置であって、
前記支持具７は支柱５を昇降可能でかつ倒れを防止した状態で嵌合する嵌合部７ａと、この嵌合部７ａに嵌合した支柱５下部を固定する固定手段８とを有しており、
前記支柱５は、上下方向に長い支柱本体５Ａの上部に、上端に側桟部材６と連結しかつ支柱本体５Ａの上方に伸張された伸張姿勢Ｅと、支柱本体５Ａを屈曲して略水平方向姿勢にする屈曲姿勢Ｋとに姿勢変更可能な屈伸連結体９を設けていることを特徴する。 The specific means for solving the problems in the present invention is a scaffolding platform device comprising a rectangular scaffolding board 3 having both end edges 3a and both side edges 3b, and side frames 4 arranged along each side edge 3b of the scaffolding board 3, the side frames 4 having a pair of posts 5 and side rail members 6 connected to the upper ends of the posts 5, and the lower part of each of the posts 5 is attached to fixed supports 7 at both ends of each side edge 3b,
The support 7 has a fitting portion 7a that fits the support 5 in a state in which the support 5 can be raised and lowered and is prevented from falling over, and a fixing means 8 that fixes the lower part of the support 5 that is fitted into the fitting portion 7a,
The pillar 5 is characterized in that, at the top of the pillar main body 5A which is long in the vertical direction, there is provided a bending/extending connector 9 which is connected to the upper end of the side rail member 6 and can be changed between an extended position E in which the pillar main body 5A is extended above the pillar main body 5A, and a bent position K in which the pillar main body 5A is bent to an approximately horizontal position.

本発明によれば、側枠の剛性を維持したまま足場板に側枠を折り畳むことができる。
即ち、側桟部材６と連結される支柱５を支持具７の嵌合部７ａに昇降可能でかつ倒れを防止した状態で嵌合するので、側枠４は剛性が低下されることがなく、固定手段８を解除して屈伸連結体９を嵌合部７ａ内に配置して、屈伸連結体９を屈曲することにより、支柱本体５Ａを足場板３に沿うように折り畳むことができる。 According to the present invention, the side frame can be folded onto the scaffolding board while maintaining the rigidity of the side frame.
In other words, the support 5 connected to the side rail member 6 is fitted into the fitting portion 7a of the support device 7 in a state where it can be raised and lowered and is prevented from falling over, so that the rigidity of the side frame 4 is not reduced, and by releasing the fixing means 8 and placing the bending and extension connecting body 9 in the fitting portion 7a and bending the bending and extension connecting body 9, the support main body 5A can be folded so as to fit along the scaffolding board 3.

以下、本発明の実施の形態を図面に基づいて説明する。
図１において、足場台装置１は、両端縁３ａと両側縁３ｂとを有する矩形状の足場板３と、この足場板３の各側縁３ｂに沿って立設配置された側枠４とを備え、さらに一対の側枠４には、一方から他方まで掛け渡されて足場板３の端縁３ａを作業者に知覚させる感知バー１０を設けている。この足場台装置１は仮設足場上に載置し、複数台を直線配置することができる。 Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
1, the scaffolding platform device 1 comprises a rectangular scaffolding board 3 having both ends 3a and both sides 3b, and side frames 4 arranged upright along each side edge 3b of the scaffolding board 3, and furthermore, a pair of side frames 4 are provided with sensing bars 10 that span from one side to the other and allow a worker to sense the edge 3a of the scaffolding board 3. This scaffolding platform device 1 can be placed on a temporary scaffold, and multiple units can be arranged in a straight line.

また、足場台装置１は、図２に示すように、側枠４に加えて、矩形状の足場板３の両側縁３ｂの端部にブラケット１２を固定し、このブラケット１２に立地姿勢Ｒと足場板３の下面に略沿う折り畳み姿勢Ｔとに姿勢変更可能な脚体１３を連結している。この足場台装置１は可搬式となり、作業現場にて独立して配置することができる。
図１～１０において、前記足場板３は、長方形の上板の下面に複数本のリブを一体に有する長方形単板３Ａを形成し、この長方形単板３Ａを２枚並列しており、足場板３の両側縁３ｂの両端部に支持具７を配置し、対の支持具７が２組で２枚の単板３Ａを挟むようにして締結手段１４で挟持固定している。 2, in addition to the side frames 4, the scaffolding device 1 has brackets 12 fixed to the ends of both side edges 3b of the rectangular scaffolding board 3, and legs 13 that can be changed between a standing position R and a folded position T that is generally along the underside of the scaffolding board 3 are connected to the brackets 12. The scaffolding device 1 is portable and can be independently arranged at a work site.
1 to 10, the scaffolding board 3 forms a rectangular veneer 3A having multiple ribs integrally formed on the underside of a rectangular upper plate, and two of these rectangular veneers 3A are arranged in parallel. Supports 7 are arranged at both ends of both side edges 3b of the scaffolding board 3, and the two sets of pairs of support devices 7 sandwich the two veneers 3A together and secure them in place with fastening means 14.

締結手段１４は２本の締結棒２１と一対の裏当て材２２とを有する。締結棒２１は単板３Ａ上面に宛がわれ、両端のＬ字状に屈曲された締結部２１ａが支持具７と裏当て材２２とに貫通され、ナット２３が螺合される。
ナット２３の螺合により、裏当て材２２は支持具７の下面と足場板３の側縁３ｂに押し当てられ、２枚の単板３Ａ、一対の支持具７及び裏当て材２２を挟持固定する。 The fastening means 14 has two fastening rods 21 and a pair of backing materials 22. The fastening rods 21 are placed on the upper surface of the veneer 3A, and fastening portions 21a bent into an L-shape at both ends are passed through the support 7 and the backing materials 22, and nuts 23 are screwed into them.
By screwing the nut 23, the backing material 22 is pressed against the underside of the support 7 and the side edge 3b of the scaffolding board 3, clamping and fixing the two veneers 3A, the pair of supports 7 and the backing material 22.

締結手段１４は足場板３に一対の支持具７及び裏当て材２２を締結固定した状態で、締結棒２１は足場板３の端縁３ａ付近の上面に位置することになり、その存在が足場板３上で作業をする作業者に足下での足場板３の端縁３ａを知覚することを可能にする。なお、締結棒２１は１本でもよい。
前記支持具７は上下に貫通した角筒形状の嵌合部７ａが形成され、この嵌合部７ａの足場板３と面する面と反対側の外面に２条のリブ兼案内をする凸条部７ｂが形成され、支持具７同士が対向する側の壁にはガイド溝７ｃが形成されている。 With the fastening means 14 fastening and fixing the pair of supports 7 and the backing material 22 to the scaffolding board 3, the fastening rod 21 is positioned on the upper surface of the scaffolding board 3 near the edge 3a, and its presence enables a worker working on the scaffolding board 3 to feel the edge 3a of the scaffolding board 3 under his feet. Note that the number of fastening rods 21 may be one.
The support 7 has a square cylindrical fitting portion 7a that penetrates vertically, and two ribs and ridges 7b that act as guides are formed on the outer surface of the fitting portion 7a opposite the surface facing the scaffolding board 3, and a guide groove 7c is formed in the wall on the side where the supports 7 face each other.

前記嵌合部７ａは支柱５を昇降可能でかつ倒れを防止した状態で嵌合する。前記２条の凸条部７ｂ間には嵌合部７ａに嵌合した支柱５の下部を固定する固定手段８が配置される。前記ガイド溝７ｃは後述する屈伸連結体９の屈曲部材２８が挿入される。
足場板３の各側縁３ｂに沿って配置される側枠４は、足場板３上で作業する作業員に側縁３ｂの存在を知らしめ、また手摺りとなるものであり、一対の支柱５と、この支柱５の上端に連結される側桟部材６とを有し、各支柱５の下部が支持具７の嵌合部７ａに嵌合装着される。 The fitting portion 7a fits the support 5 in a state in which the support 5 can be raised and lowered and is prevented from falling over. A fixing means 8 for fixing the lower part of the support 5 fitted into the fitting portion 7a is disposed between the two protruding strips 7b. A bending member 28 of the bending and extension connector 9, which will be described later, is inserted into the guide groove 7c.
The side frames 4, which are arranged along each side edge 3b of the scaffolding board 3, inform workers working on the scaffolding board 3 of the presence of the side edges 3b and also serve as handrails.The side frames 4 have a pair of posts 5 and side railing members 6 connected to the upper ends of the posts 5, and the lower parts of the posts 5 are fitted into the fitting portions 7a of the supports 7.

前記支柱５は、上下方向に長い断面角形状の支柱本体５Ａと、この支柱本体５Ａの上部に伸張姿勢Ｅと屈曲姿勢Ｋとに姿勢変更可能に連結されかつ側桟部材６と連結された屈伸連結体９とを有している。
前記支柱本体５Ａは、支持具７から立設された姿勢で前記固定手段８の固定棒２５が係止される２つの係止部ｍ１、ｍ２を有し、上端にはスリット状の係合凹部５ａが形成されている。 The support 5 has a support body 5A having an angular cross-sectional shape that is long in the vertical direction, and a bending/extending connecting body 9 that is connected to the upper part of the support body 5A so that its position can be changed between an extended position E and a bent position K, and is connected to a side rail member 6.
The pillar body 5A has two locking portions m1, m2 to which the fixing rod 25 of the fixing means 8 is locked in a position in which the pillar body 5A is erected from the support 7, and a slit-shaped engagement recess 5a is formed at the upper end.

固定手段８の固定棒２５は略Ｌ字形状であって、この固定棒２５は中間の直線部２５ａの一端から屈曲した長尺足２５ｂを有し、この長尺足２５ｂが支柱本体５Ａの下係止部ｍ２に挿入されかつスプリング２６によって挿入方向に付勢されている。また、直線部２５ａの他端から屈曲した短尺足２５ｃを有し、支柱本体５Ａの上係止部ｍ１に係脱自在に係合される。 The fixed rod 25 of the fixing means 8 is roughly L-shaped, and has a long leg 25b bent from one end of the middle straight section 25a, which is inserted into the lower locking section m2 of the support body 5A and is biased in the insertion direction by a spring 26. It also has a short leg 25c bent from the other end of the straight section 25a, which is detachably engaged with the upper locking section m1 of the support body 5A.

前記固定手段８は固定棒２５の直線部２５ａを支持具７の２条の凸条部７ｂ間に入るように嵌合部７ａに宛がうことにより、支柱本体５Ａを嵌合部７ａに対して上下位置を規制した状態で固定する。
固定手段８の固定棒２５はスプリング２６に抗して移動することにより、短尺足２５ｃを上係止部ｍ１から離脱可能であり、これを離脱することにより、支柱本体５Ａは嵌合部７ａに対して下方へ摺動可能になる。また、短尺足２５ｃが係合可能な補助係止部ｍ３は側桟部材６に形成されている。 The fixing means 8 fixes the pillar body 5A in a state where its vertical position is restricted relative to the fitting portion 7a by fitting the straight portion 25a of the fixing rod 25 to the fitting portion 7a so that it fits between the two convex strip portions 7b of the support 7.
The fixing rod 25 of the fixing means 8 moves against the spring 26, so that the short leg 25c can be released from the upper locking portion m1, and by releasing this, the support body 5A can slide downward relative to the fitting portion 7a. In addition, the auxiliary locking portion m3 with which the short leg 25c can be engaged is formed on the side rail member 6.

図３～５において、屈伸連結体９は、直径方向に貫通する上下スリット２７ａ，２７ｂを形成した筒形状の鉛直部材２７と、この鉛直部材２７の下部と支柱本体５Ａの上部とに渡って挿入された楔形状の屈曲部材２８とを有している。
鉛直部材２７の上スリット２７ａには側桟部材６が嵌入され、ピン２９で直交状態に連結固定されている。鉛直部材２７の下スリット２７ｂには屈曲部材２８の上部が挿入され回動ピン３０で連結されている。 In Figures 3 to 5, the bending and extension connecting body 9 has a cylindrical vertical member 27 having upper and lower slits 27a, 27b that penetrate in the diametrical direction, and a wedge-shaped bending member 28 inserted between the lower part of the vertical member 27 and the upper part of the support main body 5A.
The side rail member 6 is fitted into the upper slit 27a of the vertical member 27 and is connected and fixed perpendicularly by a pin 29. The upper part of the bending member 28 is inserted into the lower slit 27b of the vertical member 27 and is connected by a pivot pin 30.

屈曲部材２８は下部がＬ字状に屈曲され、支柱本体５Ａの上部に入って係合凹部５ａに係合されて回り止めされ、ピン３１によって連結固定されている。
屈曲部材２８の上部は山形状（楔形状）になっており、その中央に前記回動ピン３０が挿通される上下方向に長い長孔３３が形成され、山形状の裾の部分には、鉛直部材２７の内側に楔状に入って係合する回動規制部３４と、下スリット２７ｂに嵌入する位置規制部３５と、この位置規制部３５より下側で支柱本体５Ａの係合凹部５ａに係合する固定片部３６とが形成されている。 The bending member 28 has its lower portion bent into an L-shape, inserted into the upper portion of the support body 5A and engaged with the engaging recess 5a to prevent it from rotating, and is connected and fixed by a pin 31.
The upper part of the bending member 28 is shaped like a mountain (wedge), and in the center of the mountain is formed a long hole 33 that is long in the vertical direction through which the pivot pin 30 is inserted. At the base of the mountain shape are formed a pivot control portion 34 that engages with the inside of the vertical member 27 in a wedge-like shape, a position control portion 35 that fits into the lower slit 27b, and a fixed piece portion 36 that engages with the engagement recess 5a of the pillar main body 5A below this position control portion 35.

なお、位置規制部３５の幅は鉛直部材２７の直径に略等しく、固定片部３６の幅は支柱本体５Ａの一辺幅に略等しく形成されているが、位置規制部３５の幅を固定片部３６の幅と同一にしてもよい。
前記屈曲部材２８は回動規制部３４が鉛直部材２７の内面に当接し、位置規制部３５が下スリット２７ｂに嵌入すると、回動ピン３０周りの相対回動は規制され、支柱本体５Ａから直上方向に延びる伸張姿勢Ｅ（図１～５に示す。）となる。 In addition, the width of the position regulating portion 35 is approximately equal to the diameter of the vertical member 27, and the width of the fixed piece portion 36 is approximately equal to the width of one side of the pillar main body 5A, but the width of the position regulating portion 35 may be the same as the width of the fixed piece portion 36.
When the rotation control portion 34 of the bending member 28 abuts against the inner surface of the vertical member 27 and the position control portion 35 fits into the lower slit 27b, the relative rotation around the pivot pin 30 is restricted and the bending member 28 assumes an extended position E (shown in Figures 1 to 5) extending straight upward from the support body 5A.

前記屈伸連結体９は、固定手段８を解除して嵌合部７ａ内で支柱５を下降し、屈伸連結体９を嵌合部７ａ内に配置したときに、支柱本体５Ａとの連結部を嵌合部７ａの下方に、側桟部材６との連結部を嵌合部７ａの上方にそれぞれ配置する上下寸法Ｌを有する。即ち、鉛直部材２７は上下スリット２７ａ，２７ｂ間の寸法Ｌａが嵌合部７ａの上面からガイド溝７ｃの上端までの寸法Ｌｂと略等しくなっている。 The bending and extension connecting body 9 has a vertical dimension L such that when the fixing means 8 is released, the support 5 is lowered within the fitting portion 7a, and the bending and extension connecting body 9 is placed within the fitting portion 7a, the connecting portion with the support body 5A is located below the fitting portion 7a and the connecting portion with the side rail member 6 is located above the fitting portion 7a. In other words, the vertical member 27 has a dimension La between the upper and lower slits 27a, 27b that is approximately equal to the dimension Lb from the top surface of the fitting portion 7a to the upper end of the guide groove 7c.

前記屈曲部材２８は長孔３３の範囲内で鉛直部材２７から引き離す方向に移動し、回動規制部３４を鉛直部材２７の内面から離脱させ、位置規制部３５を下スリット２７ｂから離脱させると、回動ピン３０周りの相対回動は許容され、屈伸連結体９は中途部で屈曲することができる。即ち、鉛直部材２７に対して屈曲部材２８及び支柱本体５Ａを回動ピン３０周りに回動して屈曲姿勢Ｋ（図７、８、１０に示す）にすることができる。 When the bending member 28 moves within the range of the long hole 33 in a direction away from the vertical member 27, the rotation restriction part 34 is released from the inner surface of the vertical member 27, and the position restriction part 35 is released from the lower slit 27b, relative rotation around the pivot pin 30 is permitted and the bending/extending connector 9 can bend at its midpoint. In other words, the bending member 28 and the support body 5A can be rotated around the pivot pin 30 relative to the vertical member 27 to assume the bent position K (shown in Figures 7, 8, and 10).

前記支柱５は屈曲部材２８及び支柱本体５Ａと鉛直部材２７とをＬ字状に屈曲して折り畳み可能な構成であり、鉛直部材２７を嵌合部７ａ内まで下降したとき、側桟部材６は嵌合部７ａの上面に当接し、屈曲部材２８は長孔３３の分だけ鉛直部材２７に対して下降する。
この状態で屈曲部材２８及び支柱本体５Ａは回動ピン３０を中心に回動が可能になり、略９０度回動すると、屈曲部材２８は位置規制部３５が下スリット２７ｂに嵌入するとともに嵌合部７ａのガイド溝７ｃにも嵌入し、略水平方向姿勢で振れ止めがなされた状態で支柱本体５Ａは屈曲姿勢Ｋになる。 The support 5 is configured to be foldable by bending the bending member 28, the support main body 5A, and the vertical member 27 into an L shape, and when the vertical member 27 is lowered into the fitting portion 7a, the side rail member 6 abuts against the upper surface of the fitting portion 7a, and the bending member 28 descends relative to the vertical member 27 by the amount of the long hole 33.
In this state, the bending member 28 and the support main body 5A become able to rotate around the pivot pin 30, and when rotated approximately 90 degrees, the position control portion 35 of the bending member 28 fits into the lower slit 27b and also fits into the guide groove 7c of the fitting portion 7a, and the support main body 5A assumes the bent position K with the vibration-proofing provided in an approximately horizontal position.

図１～１０において、前記各側枠４は足場板３の各端縁３ａの上方に配置する感知バー１０を１本ずつ有している。前記感知バー１０は、一端に一方の側桟部材６に枢支された枢軸部１０ａを有し、他端に前記一方の側桟部材６に沿った位置で係合する係合部１０ｂを有し、他方の側桟部材６に前記係合部１０ｂが掛け渡しのために係合する被係合部ｈ１が形成されている。 In Figures 1 to 10, each side frame 4 has one sensing bar 10 disposed above each edge 3a of the scaffolding board 3. The sensing bar 10 has a pivot portion 10a pivotally supported on one side rail member 6 at one end, and an engaging portion 10b that engages at a position along the one side rail member 6 at the other end, and an engaged portion h1 is formed on the other side rail member 6 with which the engaging portion 10b engages for hanging.

前記枢軸部１０ａは側桟部材６に挿入されていて、スプリング４１によって添接するように付勢されており、スプリング４１に抗して引き上げることにより係合部１０ｂを被係合部ｈ１から離脱することができる。
感知バー１０は、係合部１０ｂを被係合部ｈ１に係合することにより、一方の側桟部材６から他方の側桟部材６まで掛け渡されて足場板３の端縁３ａを作業者に知覚させる作用状態になるが、収納するときは、枢軸部１０ａが枢支されている側の側桟部材６の中途部に形成した収納被係合部ｈ２に係合部１０ｂを係合して、側桟部材６の上面に沿わせるようにする。 The pivot portion 10a is inserted into the side rail member 6 and is biased by a spring 41 so that it comes into contact with the side rail member 6. By pulling up against the spring 41, the engaging portion 10b can be released from the engaged portion h1.
By engaging the engaging portion 10b with the engaged portion h1, the sensing bar 10 is hung from one side rail member 6 to the other side rail member 6, and is in an operative state that allows the worker to sense the edge 3a of the scaffolding board 3. When storing, the engaging portion 10b is engaged with the storage engaged portion h2 formed in the middle of the side rail member 6 on the side to which the pivot portion 10a is pivotally supported, and is aligned along the top surface of the side rail member 6.

側桟部材６の中途部の側面には、折り畳み用補助係止部ｍ３が形成されている。この補助係止部ｍ３には固定手段８の固定棒２５の短尺足２５ｃが係合する。支柱本体５Ａを折り畳んだときに、固定棒２５を支柱本体５Ａから側桟部材６に渡って架設することにより、支柱本体５Ａの折り畳み姿勢を維持できるようにしている。この場合、折り畳まれた側桟部材６が足場板３から浮き上がるのも防止できる。 An auxiliary locking portion m3 for folding is formed on the side of the middle part of the side rail member 6. The short leg 25c of the fixing rod 25 of the fixing means 8 engages with this auxiliary locking portion m3. When the support body 5A is folded, the fixing rod 25 is installed across from the support body 5A to the side rail member 6, so that the folded position of the support body 5A can be maintained. In this case, the folded side rail member 6 can also be prevented from floating up from the scaffolding board 3.

図１に示す使用状態の足場台装置１は、単板３Ａを２枚並列し、この２枚の単板３Ａを挟んで両端部側にそれぞれ一対の支持具７を配置し、２枚の単板と各対の支持具７とを同時に締結手段１４で挟持固定して足場板３を構成し、足場板３の各側縁３ｂに配置された支持具７に側枠４を立設している。
側枠４の支柱５は、支柱本体５Ａの下部が嵌合部７ａに嵌入され、２つの係止部ｍ１、ｍ２に固定手段８の固定棒２５の両端が係止され、固定棒２５は嵌合部７ａに跨がるように固定されて、支柱本体５Ａを支持具７に立設姿勢に固定する。 The scaffolding platform device 1 in use as shown in Figure 1 has two veneers 3A arranged in parallel, with a pair of supports 7 placed on each end side of the two veneers 3A in between, and the two veneers and each pair of supports 7 are simultaneously clamped and fixed with fastening means 14 to form the scaffolding board 3, with side frames 4 erected on the supports 7 arranged on each side edge 3b of the scaffolding board 3.
The lower part of the pillar main body 5A of the support 5 of the side frame 4 is fitted into the fitting portion 7a, and both ends of the fixing rod 25 of the fixing means 8 are engaged with the two engagement portions m1 and m2, and the fixing rod 25 is fixed so as to straddle the fitting portion 7a, thereby fixing the pillar main body 5A to the support device 7 in an upright position.

支柱本体５Ａの上端には、屈伸連結体９の屈曲部材２８の下部が固定されており、この屈曲部材２８に鉛直部材２７の下スリット２７ｂが嵌合して、支柱本体５Ａの上端に屈伸連結体９が伸張姿勢Ｅで保持される。
鉛直部材２７の上スリット２７ａには側桟部材６が嵌入され、屈伸連結体９と側桟部材６とはピン２９が貫通されてＴ字状に結合されており、側枠４の支柱５と側桟部材６とは側面視門形の強固な手摺り構造体となる。 The lower part of the bending member 28 of the bending/extension connecting body 9 is fixed to the upper end of the support main body 5A, and the lower slit 27b of the vertical member 27 is fitted into this bending member 28, so that the bending/extension connecting body 9 is held in an extended position E at the upper end of the support main body 5A.
The side rail member 6 is inserted into the upper slit 27a of the vertical member 27, and the bending/extending connecting body 9 and the side rail member 6 are connected in a T-shape by a pin 29 passing through it, and the support pillar 5 of the side frame 4 and the side rail member 6 form a sturdy handrail structure that is gate-shaped when viewed from the side.

一対の側枠４は、一対の側桟部材６の互いに反対側の端部近傍に感知バー１０の一端の枢軸部１０ａを枢支している。この枢軸部１０ａを引き抜くように感知バー１０を上方移動すると、感知バー１０は枢軸部１０ａを中心に回動でき、感知バー１０の他端の係合部１０ｂを他方の側桟部材６に形成した被係合部ｈ１に係合することにより、感知バー１０は２本の側桟部材６に掛け渡される。 The pair of side frames 4 support the pivot portion 10a at one end of the sensing bar 10 near the opposite ends of the pair of side rail members 6. When the sensing bar 10 is moved upward as if to pull out this pivot portion 10a, the sensing bar 10 can rotate around the pivot portion 10a, and the engagement portion 10b at the other end of the sensing bar 10 engages with the engaged portion h1 formed on the other side rail member 6, so that the sensing bar 10 is suspended across the two side rail members 6.

感知バー１０は足場板３の各端縁３ａの位置を作業者に知覚させ、足場板３上からの不本意な逸脱を防止することができる。
足場台装置１を前記使用状態から折り畳み状態にするときは、まず、感知バー１０を引き上げてそれを枢支している側桟部材６に沿う状態まで回動し、係合部１０ｂを収納被係合部ｈ２に係合して、側桟部材６に添接する状態に収納する。 The sensing bar 10 allows the worker to perceive the position of each edge 3a of the scaffolding board 3, and prevents unintentional deviation from the scaffolding board 3.
When changing the scaffolding device 1 from the usage state to the folded state, first the sensing bar 10 is pulled up and rotated until it is aligned with the side rail member 6 to which it is pivoted, and then the engaging portion 10b engages with the storage engaged portion h2, and the scaffolding device 1 is stored in a state in which it is abutted against the side rail member 6.

次に、固定手段８の固定を解除して、支柱本体５Ａを嵌合部７ａ内で摺動下降させ、屈伸連結体９を嵌合部７ａ内に挿入させ、側桟部材６を足場板３の側縁３ｂに略沿う位置まで下降させる。
下降した側桟部材６は嵌合部７ａの上端に当接し、鉛直部材２７は嵌合部７ａ内に収まり、屈曲部材２８は鉛直部材２７に対して長孔３３の範囲内でさらに下降し、回動規制部３４及び位置規制部３５が鉛直部材２７の下スリット２７ｂから下降し、伸張姿勢Ｅが解消されて回動ピン３０周りの相対回動が可能な状態になる。 Next, the fixing means 8 is released, the support main body 5A is slid down within the fitting portion 7a, the bending and extension connecting body 9 is inserted into the fitting portion 7a, and the side rail member 6 is lowered to a position approximately along the side edge 3b of the scaffolding board 3.
The lowered side rail member 6 abuts against the upper end of the fitting portion 7a, the vertical member 27 fits within the fitting portion 7a, the bending member 28 descends further within the range of the long hole 33 relative to the vertical member 27, the rotation control portion 34 and the position control portion 35 descend from the lower slit 27b of the vertical member 27, the extended position E is eliminated, and relative rotation around the pivot pin 30 becomes possible.

屈曲部材２８の上端は略山形形状であるので、回動ピン３０周りに回動すると、屈曲部材２８の位置規制部３５は嵌合部７ａのガイド溝７ｃに挿入され（下スリット２７ｂにも挿入されている。）、支柱本体５Ａは屈曲姿勢Ｋとなって下降した側桟部材６に略沿うようになる。
前記解除した固定手段８の固定棒２５は、長尺足２５ｂが支柱本体５Ａの下係止部ｍ２に挿入されたままであるが、短尺足２５ｃが支柱本体５Ａの上係止部ｍ１から離脱しており、この短尺足２５ｃを側桟部材６の補助係止部ｍ３に係合することにより、支柱本体５Ａは側桟部材６側に折り畳まれて屈曲姿勢Ｋが保持される。 Since the upper end of the bending member 28 is approximately mountain-shaped, when it rotates around the pivot pin 30, the position regulating portion 35 of the bending member 28 is inserted into the guide groove 7c of the fitting portion 7a (also inserted into the lower slit 27b), and the support main body 5A assumes a bent posture K and approximately aligns with the lowered side rail member 6.
The fixed rod 25 of the released fixing means 8 has its long leg 25b still inserted into the lower engagement portion m2 of the pillar main body 5A, but its short leg 25c has disengaged from the upper engagement portion m1 of the pillar main body 5A. By engaging this short leg 25c with the auxiliary engagement portion m3 of the side rail member 6, the pillar main body 5A is folded toward the side rail member 6 and the bent posture K is maintained.

前述した実施形態の足場台装置１においては、両端縁３ａと両側縁３ｂとを有する矩形状の足場板３と、この足場板３の各側縁３ｂに沿って配置された側枠４とを備えており、前記側枠４は一対の支柱５と、この支柱５の上端に連結される側桟部材６とを有し、前記各支柱５の下部は各側縁３ｂの両端部に固定の支持具７に装着されている足場台装置であって、前記支持具７は支柱５を昇降可能でかつ倒れを防止した状態で嵌合する嵌合部７ａと、この嵌合部７ａに嵌合した支柱５下部を固定する固定手段８とを有しており、前記支柱５は、上下方向に長い支柱本体５Ａの上部に、上端に側桟部材６と連結しかつ支柱本体５Ａの上方に伸張された伸張姿勢Ｅと、支柱本体５Ａを屈曲して略水平方向姿勢にする屈曲姿勢Ｋとに姿勢変更可能な屈伸連結体９を設けているので、固定手段８を解除して、側桟部材６と共に一対の支柱５を降下させて、屈伸連結体９を嵌合部７ａ内に配置すると、支柱本体５Ａを屈曲して足場板３の各側縁３ｂに沿わせることができ、足場板３に対して側枠４を折り畳むことができ、側枠４は足場板３から立設された使用姿勢の時、屈伸連結体９は支柱本体５Ａの上部に伸張姿勢Ｅになるので、枠としての剛性を強固に維持できる。 The scaffolding device 1 of the above-mentioned embodiment is equipped with a rectangular scaffolding board 3 having both end edges 3a and both side edges 3b, and a side frame 4 arranged along each side edge 3b of the scaffolding board 3. The side frame 4 has a pair of posts 5 and a side rail member 6 connected to the upper end of the posts 5. The lower part of each post 5 is attached to a fixed support 7 at both ends of each side edge 3b. The support 7 has a fitting part 7a that fits the post 5 in a state where it can be raised and lowered and is prevented from falling over, and a fixing means 8 that fixes the lower part of the post 5 fitted to the fitting part 7a. The post 5 is attached to the upper part of the post main body 5A that is long in the vertical direction. The upper end of the bending/extending connector 9 is connected to the side rail member 6 and can be moved between an extended position E in which it is extended above the main pillar body 5A, and a bent position K in which the main pillar body 5A is bent into a substantially horizontal position. When the fixing means 8 is released and the pair of pillars 5 are lowered together with the side rail member 6, and the bending/extending connector 9 is placed in the fitting portion 7a, the main pillar body 5A can be bent to fit along each side edge 3b of the scaffolding board 3, and the side frame 4 can be folded against the scaffolding board 3. When the side frame 4 is in the usage position erected from the scaffolding board 3, the bending/extending connector 9 is in the extended position E above the main pillar body 5A, so the rigidity of the frame can be firmly maintained.

また、足場台装置１においては、屈伸連結体９は、上端が側桟部材６に連結された鉛直部材２７と、下部が支柱本体５Ａの上部に固定された屈曲部材２８とを有し、鉛直部材２７と屈曲部材２８とは、屈曲部材２８の上部に鉛直部材２７の下部を係合して伸張姿勢Ｅとなりかつ屈曲部材２８の上部を鉛直部材２７の下部から離脱しかつ回動して屈曲姿勢Ｋとなるべく連結されているので、屈伸連結体９だけで支柱５の立設と折り畳みとができる。 In addition, in the scaffolding device 1, the bending/extending connector 9 has a vertical member 27 whose upper end is connected to the side rail member 6, and a bending member 28 whose lower part is fixed to the upper part of the support body 5A. The vertical member 27 and the bending member 28 are connected so that the lower part of the vertical member 27 engages with the upper part of the bending member 28 to assume the extended position E, and the upper part of the bending member 28 disengages from the lower part of the vertical member 27 and rotates to assume the bent position K. Therefore, the support 5 can be erected and folded using only the bending/extending connector 9.

さらに、足場台装置１においては、足場板３の端縁３ａを作業者に知覚させる感知バー１０が一方の側桟部材６から他方の側桟部材６まで掛け渡されているので、感知バー１０を他方の側桟部材６に掛け渡すことにより、足場板３上で作業をする作業者に足場板３の端縁３ａを知覚させることができる。
さらにまた、足場台装置１においては、感知バー１０は、一端に一方の側桟部材６に枢支された枢軸部１０ａを有し、他端に前記一方の側桟部材６に沿った位置で係合する係合部１０ｂを有し、他方の側桟部材６に前記係合部１０ｂが掛け渡しのために係合する被係合部ｈ１が形成されているので、側桟部材６を折り畳むときは感知バー１０を側桟部材６に沿わせることができる。 Furthermore, in the scaffolding platform device 1, a sensing bar 10 that allows a worker to perceive the edge 3a of the scaffolding board 3 is hung from one side rail member 6 to the other side rail member 6, so that by hanging the sensing bar 10 to the other side rail member 6, the worker working on the scaffolding board 3 can perceive the edge 3a of the scaffolding board 3.
Furthermore, in the scaffolding device 1, the sensing bar 10 has at one end a pivot portion 10a pivoted to one of the side rail members 6, and at the other end an engaging portion 10b which engages at a position along the one of the side rail members 6, and an engaged portion h1 is formed on the other side rail member 6 with which the engaging portion 10b engages for hanging, so that when the side rail member 6 is folded, the sensing bar 10 can be aligned along the side rail member 6.

そして、足場台装置１においては、支柱本体５Ａは、支持具７から立設された姿勢で前記固定手段８が係止される２つの係止部ｍ１、ｍ２を有し、前記屈伸連結体９に対して支柱本体５Ａを屈曲したときに、２つの係止部ｍ１、ｍ２の一方と係止した前記固定手段８を係止する補助係止部ｍ３を側桟部材６に形成しているので、支柱本体５Ａを支持具７から立設した姿勢で固定する固定手段８を用いて、屈伸連結体９から屈曲した支柱本体５Ａを側桟部材６に係止することができる。 In the scaffolding device 1, the pillar body 5A has two locking portions m1, m2 to which the fixing means 8 is locked in an upright position from the support 7, and when the pillar body 5A is bent relative to the bending and extension connecting body 9, an auxiliary locking portion m3 is formed on the side rail member 6 to lock the fixing means 8 that is locked with one of the two locking portions m1, m2. Therefore, the pillar body 5A bent from the bending and extension connecting body 9 can be locked to the side rail member 6 using the fixing means 8 that fixes the pillar body 5A in an upright position from the support 7.

そしてまた、足場台装置１においては、両端縁３ａと両側縁３ｂとを有する矩形状の足場板３の両側縁３ｂの端部にブラケット１２が固定され、このブラケット１２に立地姿勢Ｒと足場板３の下面に略沿う折り畳み姿勢Ｔとに姿勢変更可能な脚体１３が連結されているので、独立設置可能な装置として構成でき、かつ足場板３に沿うように、一対の側枠４も脚体１３も折り畳むことができる。 Furthermore, in the scaffolding device 1, a bracket 12 is fixed to the end of both side edges 3b of a rectangular scaffolding board 3 having both end edges 3a and both side edges 3b, and legs 13 that can be changed between a standing position R and a folded position T that roughly follows the underside of the scaffolding board 3 are connected to this bracket 12, so that it can be configured as an independently installable device, and both the pair of side frames 4 and the legs 13 can be folded to follow the scaffolding board 3.

また、足場台装置１においては、足場板３は長方形単板３Ａを２枚並列され、２枚の単板３Ａを挟んで一対の支持具７が配置され、２枚の単板と一対の支持具７とを同時に締結手段１４で挟持固定しているので、２枚の単板３Ａ及び一対の支持具７を締結手段１４で挟持固定して、足場板３を簡単かつ強固に組み立て構成することができる。
さらに、足場台装置１においては、前記足場板３と一対の支持具７とを同時に締結手段１４で挟持固定しており、前記締結手段１４は、足場板３の端縁３ａ近傍の上面に宛がわれる締結棒２１と、支持具７と足場板３の側縁３ｂとに押し当てられて締結棒２１とともに足場板３と支持具７とを挟持する裏当て材２２とを有しているので、足場板３上で作業をする作業者に足下での足場板３の端縁３ａの知覚を可能にする。 In addition, in the scaffolding platform device 1, the scaffolding board 3 comprises two rectangular veneers 3A arranged in parallel, with a pair of supports 7 sandwiched between the two veneers 3A, and the two veneers and the pair of supports 7 are simultaneously clamped and fixed by the fastening means 14. Therefore, by clamping and fixing the two veneers 3A and the pair of supports 7 with the fastening means 14, the scaffolding board 3 can be assembled simply and firmly.
Furthermore, in the scaffolding platform device 1, the scaffolding board 3 and a pair of supports 7 are simultaneously clamped and fixed by the fastening means 14, and the fastening means 14 has a fastening rod 21 attached to the upper surface near the edge 3a of the scaffolding board 3, and a backing material 22 pressed against the supports 7 and the side edges 3b of the scaffolding board 3 to clamp the scaffolding board 3 and the supports 7 together with the fastening rod 21, thereby enabling a worker working on the scaffolding board 3 to feel the edge 3a of the scaffolding board 3 under his feet.

なお、本発明は前記実施形態に限定されるものではなく、部材の形状、構成及び組み合わせ等を変更したりすることもできる。
例えば、感知バー１０は側桟部材６間に掛け渡された位置から側桟部材６に沿う位置まで移動可能に設けられているが、一対の側桟部材６に連結固定してもよい。
また、支柱５を支持する支持具７は２枚の単板３Ａを併設する締結手段１４を兼ねているが、締結手段１４とは別個に形成して足場板３の各側縁３ｂに固定してもよい。 The present invention is not limited to the above-described embodiment, and the shapes, configurations, and combinations of the members can be changed.
For example, the sensing bar 10 is provided so as to be movable from a position spanning between the side rail members 6 to a position along the side rail members 6, but it may also be connected and fixed to a pair of side rail members 6.
In addition, the support 7 supporting the support post 5 also serves as the fastening means 14 for holding two veneers 3A side by side, but it may also be formed separately from the fastening means 14 and fixed to each side edge 3b of the scaffolding board 3.
