The insertion bar 22 can relatively take the lowest position and the uppermost position to the long hole 17 by moving along the longitudinal direction of the long hole 17, allows rocking in a lower position, and makes the rocking impossible in a state where the plate body 14 and the insertion bar 22 engage with the connection frame in an upper position.

Description

本発明は、架設用の足場に使用され、足場を補強するための筋交を備えている足場用補強部材に関するものである。   The present invention relates to a scaffold reinforcing member that is used in a scaffold for erection and has a brace for reinforcing the scaffold.

従来から建設現場等ではパイプ材を枠状に組み上げて作業用の架設の足場が組まれる。足場には通常横あるいは斜め方向からの加重に耐え得るように筋交が設けられる。このような筋交の一例として特許文献１を挙げる。特許文献１の図８に示すように、この従来の筋交５１では筋交５１の両端に固着された連結具５２を支柱５３側に形成された連結枠５４に対して連結することで筋交５１を装着するようにしている。より詳しくこの従来の連結手段を説明する。特許文献１の図９に示すように、連結具５２は連結ピン５５を有しており、この連結ピン５５を連結枠５４に挿入する。この挿入時において、くさび片５６は一旦図上２点鎖線で示す位置にて保持する。このようにくさび片５６を保持するのは、連結ピン５５を連結枠５４に挿入する際にくさび片５６が邪魔とならないようにするためである。そして、連結ピン５５にて連結具５２を連結枠５４に対して仮止めした状態で、保持状態にあったくさび片５６を把持して図上垂直方向に押し込み、更にハンマー等で打ち込んでいく。
くさび片５６は傾斜側面５６ａが上板５７及び下板５８の孔５７ａ,５８ａの内周縁に当接するため、打ち込みにつれてこれら内周縁からの反力により連結枠５４方向（連結ピン５５方向）に移動させられる。くさび片５６は図上実線で示す位置において連結枠５４に強く押し当てられ、連結ピン５５と協働して連結枠５４を挟み込む。このような作用によって連結具５２は連結枠５４に固定されることとなる。
また、特許文献２も特許文献１と同様にくさび片３３を打ち込んで筋交２１の両端の連結具１０を固定するものである（例えば、特許文献２の図３）。 Conventionally, at construction sites and the like, pipe materials are assembled into a frame shape and a working scaffold is assembled. The scaffolding is usually provided with braces so that it can withstand the load from the side or diagonal. Patent document 1 is given as an example of such a bracing. As shown in FIG. 8 of Patent Document 1, in this conventional bracing 51, bracing is performed by connecting a connecting tool 52 fixed to both ends of the bracing 51 to a connecting frame 54 formed on the column 53 side. 51 is installed. This conventional connecting means will be described in more detail. As shown in FIG. 9 of Patent Document 1, the connection tool 52 has a connection pin 55, and the connection pin 55 is inserted into the connection frame 54. At the time of this insertion, the wedge piece 56 is temporarily held at a position indicated by a two-dot chain line in the drawing. The reason why the wedge piece 56 is held in this manner is to prevent the wedge piece 56 from becoming an obstacle when the connecting pin 55 is inserted into the connecting frame 54. Then, in a state where the connection tool 52 is temporarily fixed to the connection frame 54 with the connection pin 55, the wedge piece 56 in the holding state is gripped and pushed in the vertical direction in the figure, and further driven with a hammer or the like.
Since the inclined side surface 56a contacts the inner peripheral edge of the holes 57a and 58a of the upper plate 57 and the lower plate 58, the wedge piece 56 moves in the direction of the connection frame 54 (direction of the connection pin 55) by the reaction force from these inner peripheral edges as it is driven. Be made. The wedge piece 56 is strongly pressed against the connecting frame 54 at a position indicated by a solid line in the figure, and sandwiches the connecting frame 54 in cooperation with the connecting pin 55. By such an action, the connecting tool 52 is fixed to the connecting frame 54.
In addition, Patent Document 2 also drives the wedge piece 33 in the same manner as Patent Document 1 to fix the connecting tools 10 at both ends of the brace 21 (for example, FIG. 3 of Patent Document 2).

上記のように、従来の架設足場において筋交を取り付ける場合にはくさび片を打ち込むことが前提であった。しかし、常にくさび片を必要とするということは、少なくともくさび片を打ち込むための連結部分（連結具）が作業者の作業できる位置にあることが前提となる。つまり、作業者は筋交を斜め上下方向に配置するためには上側に配置される連結部分（連結具）にくさび片を打ち込むために上側の作業位置で作業をし、更に下側に配置される連結部分（連結具）にくさび片を打ち込むために下側の作業位置でも作業をしなければならないわけである。そのため、従来では筋交を備えている足場用補強部材を設置するための作業効率が非常に悪かった。
本発明は、このような従来の技術に存在する問題点に着目してなされたものである。その目的とするところは、筋交を配置する際に上側の連結部分についてくさび片の打ち込みを不要にし、作業効率を向上させた足場用補強部材を提供することにある。 As described above, it is assumed that a wedge piece is driven when attaching a brace in a conventional erection scaffold. However, the fact that a wedge piece is always required is based on the premise that at least a connecting portion (connecting tool) for driving the wedge piece is in a position where an operator can work. In other words, the operator works at the upper working position to drive the wedge piece into the connecting portion (connector) arranged on the upper side in order to arrange the braces diagonally in the vertical direction, and is further arranged on the lower side. In order to drive the wedge piece into the connecting portion (connecting tool), the work must be performed even at the lower working position. Therefore, conventionally, the work efficiency for installing the reinforcing member for scaffolding provided with braces has been very poor.
The present invention has been made paying attention to such problems existing in the prior art. An object of the present invention is to provide a scaffold reinforcing member that eliminates the need to drive a wedge piece at the upper connecting portion when arranging the braces and improves the working efficiency.

上記目的を達成するために、第１の手段では、少なくとも筋交と、同筋交の両端に装着された連結部とを備え、足場に設けられた上下方向にかけて連通された連結枠に対して前記連結部を連結させることで前記足場に前記筋交を斜め架設させるようにした足場用補強部材において、前記筋交を架設した状態で前記筋交の上方端側に配置される前記連結部は、連結部本体と、同連結部本体に形成された長孔に対して揺動可能に軸支されるとともに前記連結部本体に接近した第１の位置と揺動して先端側が外方に離間した第２の位置を取り得る挿入片とを備え、前記挿入片は前記長孔の長手方向に沿って移動することで軸部が前記長孔の最下方位置に配置される前記連結部本体に対して相対的に最も下降した位置と、前記軸部が前記長孔の最上方位置に配置される前記連結部本体に対して相対的に最も上昇した位置とを取り得るとともに、前記下方位置では前記第２の位置方向への揺動が許容され、前記上方位置では前記連結部本体側に配設されたストッパ部材と干渉して前記第２の位置方向への揺動が不能とされ、前記連結部本体又は前記挿入片の少なくとも一方には係合部が形成され、前記係合部は前記連結枠に前記連結部を連結した際に前記連結枠の下面に係合可能とされていることをその要旨とする。   In order to achieve the above object, in the first means, at least a bracing and a connecting portion attached to both ends of the bracing, with respect to a connecting frame communicated in the vertical direction provided on the scaffold In the reinforcing member for scaffolding, in which the bracing is obliquely installed on the scaffold by connecting the connecting portions, the connecting portion disposed on the upper end side of the bracing in a state where the bracing is installed, The connecting portion main body and a long hole formed in the connecting portion main body are pivotally supported so as to be swingable and swing from a first position close to the connecting portion main body, and the tip side is separated outward. An insertion piece capable of taking the second position, and the insertion piece moves along the longitudinal direction of the long hole so that the shaft portion is disposed at the lowermost position of the long hole. Position relative to the lowest position, and the shaft is at the top of the slot. A position that is relatively elevated with respect to the connecting portion main body disposed at a position, and swinging in the second position direction is allowed at the lower position, and the connecting portion is at the upper position. Interfering with the stopper member disposed on the main body side, it is impossible to swing in the second position direction, and an engaging portion is formed on at least one of the connecting portion main body or the insertion piece. The gist of the joint portion is that it can be engaged with the lower surface of the connecting frame when the connecting portion is connected to the connecting frame.

また、第２の手段では、少なくとも一対の筋交と、同各筋交の両端に装着された連結部と、前記両筋交を架設した状態で前記筋交の上方端側に隣接配置される前記連結部間に配設された先行手すりとなる水平材とを備え、前記連結部を足場に設けられた上下方向にかけて連通された連結枠に対して前記各筋交を交差するように連結することで前記足場に先行手すりを水平に架設させるようにした足場用補強部材において、前記筋交を架設した状態で前記筋交の上方端側に配置される前記連結部は、連結部本体と、同連結部本体に形成された長孔に対して揺動可能に軸支されるとともに前記連結部本体に接近した第１の位置と揺動して先端側が外方に離間した第２の位置を取り得る挿入片とを備え、前記挿入片は前記長孔の長手方向に沿って移動することで軸部が前記長孔の最下方位置に配置される前記連結部本体に対して相対的に最も下降した位置と、前記軸部が前記長孔の最上方位置に配置される前記連結部本体に対して相対的に最も上昇した位置とを取り得るとともに、前記下方位置では前記第２の位置方向への揺動が許容され、前記上方位置では前記連結部本体側に配設されたストッパ部材と干渉して前記第２の位置方向への揺動が不能とされ、前記連結部本体又は前記挿入片の少なくとも一方には係合部が形成され、前記係合部は前記連結枠に前記連結部を連結した際に前記連結枠の下面に係合可能とされていることをその要旨とする。   In the second means, at least a pair of braces, a connecting portion attached to both ends of each brace, and an upper end side of the braces are arranged adjacent to each other in a state where the braces are erected. A horizontal member serving as a preceding handrail disposed between the connecting portions, and connecting the connecting portions so as to cross the braces with respect to a connecting frame communicated in the vertical direction provided on the scaffolding. In the scaffold reinforcement member that is configured to horizontally lay the preceding handrail on the scaffold, the connecting portion disposed on the upper end side of the bracing in a state where the bracing is laid, the connecting portion main body, A second position that is pivotally supported by a long hole formed in the connecting portion main body so as to be swingable and swings from a first position approaching the connecting portion main body and the tip side is spaced outward. An insertion piece that can be taken, and the insertion piece moves along the longitudinal direction of the slot By doing so, the position where the shaft portion is relatively lowered with respect to the connection portion main body disposed at the lowest position of the long hole and the connection where the shaft portion is disposed at the uppermost position of the long hole A position that is most elevated with respect to the main body, and is allowed to swing in the second position direction at the lower position, and is disposed on the coupling main body side at the upper position. Interference with the stopper member makes the swing in the second position direction impossible, and an engaging portion is formed in at least one of the connecting portion main body or the insertion piece, and the engaging portion is attached to the connecting frame. The gist of the present invention is that when the connecting portion is connected, it can be engaged with the lower surface of the connecting frame.

これらの手段のような構成においては、使用の際には、まず挿入片をその軸部が連結部本体側の長孔の最下方位置に配置されるように連結部本体に対して相対的に下方向に移動させる。これによって挿入片は連結部本体に接近した第１の位置から離間した第２の位置方向へ揺動可能となる。この状態で足場側の連結枠に対して上方から挿入する。挿入した状態では挿入片を第１の位置に戻しておく。
次いで、足場用補強部材全体を下側に引くように操作することで挿入片は連結枠に係合されたままで、連結部本体が下降する。つまり相対的に軸部が長孔の最上方位置に配置される（挿入片は連結部本体に対して相対的に上方向に移動される）こととなる。この位置において挿入片は連結部本体側のストッパ部材と干渉して揺動できなくなる。そして、連結部本体又は挿入片の少なくとも一方に係合部が形成され、その係合部は連結枠の下面に係合可能に配置されるため、上方への引き抜き力がこの連結部にかかっても脱落してしまうことがない。
これによって、筋交の上方側に配置される連結部については連結枠に対して固定するためにくさび片を打ち込む必要がなくなるため、筋交を備えた足場用補強部材の設置の際の作業効率が向上する。また、第２の手段においては、足場用補強部材として下方位置における作業だけで先行手すりとなる水平材を上方位置にしっかりと設置することができるので、先行手すりの設置が容易となる。 In the configuration such as these means, in use, the insertion piece is first relative to the connecting portion main body so that the shaft portion is disposed at the lowest position of the long hole on the connecting portion main body side. Move down. Accordingly, the insertion piece can swing in the second position direction away from the first position approaching the connecting portion main body. In this state, it inserts from above with respect to the connecting frame on the scaffold side. In the inserted state, the insertion piece is returned to the first position.
Next, by operating the entire scaffold reinforcing member so as to be pulled downward, the connecting piece main body is lowered while the insertion piece remains engaged with the connecting frame. That is, the shaft portion is relatively disposed at the uppermost position of the long hole (the insertion piece is moved upward relative to the coupling portion main body). At this position, the insertion piece interferes with the stopper member on the connecting portion main body side and cannot swing. And since an engagement part is formed in at least one of a connection part main body or an insertion piece, and the engagement part is arrange | positioned so that engagement with the lower surface of a connection frame, upward pulling force is applied to this connection part. Will not fall off.
This eliminates the need to drive a wedge piece to fix the connecting portion arranged on the upper side of the bracing with respect to the connecting frame. Therefore, work efficiency when installing the reinforcing member for scaffolding having the bracing Will improve. Further, in the second means, the horizontal member that becomes the preceding handrail can be firmly installed at the upper position only by the work at the lower position as the reinforcing member for the scaffold, so that the preceding handrail can be easily installed.

また、第３の手段では第１又は第２の手段に加え、前記ストッパ部材は前記長孔の長手方向に沿った第１の当接面を備え、前記挿入片は前記上方位置で前記第１の当接面に面着する第２の当接面を備えていることをその要旨とする。
これは、より具体的な挿入片を揺動不能に保持するための構成であって、面同士が当接することで挿入片の揺動を規制するものである。第１及び第２の当接面は必ずしも平面である必要はない。 Further, in the third means, in addition to the first or second means, the stopper member includes a first contact surface along the longitudinal direction of the elongated hole, and the insertion piece is located at the upper position in the first position. The gist of the present invention is to provide a second abutment surface that contacts the abutment surface.
This is a configuration for holding a more specific insertion piece in a non-oscillating manner, and restricts the oscillation of the insertion piece by bringing the surfaces into contact with each other. The first and second contact surfaces do not necessarily have to be flat.

また、第４の手段では第１〜第３のいずれかの手段に加え、前記長孔の前記最下方位置に対して前記最上方位置は前記挿入片に対して遠い位置に配置されていることをその要旨とする。
これによって、挿入片が連結枠に挿入された状態で連結部本体を下降させると連結部本体は連結枠に接近することとなり、挿入片と連結枠との間のがたつきを抑えることが可能となる。更に、連結部本体に係合部を形成した場合には連結部本体を下降させると同時に連結枠に接近させることとなるため係合部を連結枠の下面位置に配置させることが可能となる。
また、第５の手段では第１〜第４のいずれかの手段に加え、前記係合部は前記連結部を連結した際に前記連結枠の下方に突出する前記挿入片の側面部分に形成された係合爪であることをその要旨とする。
これは係合部の具体的な構成であって、挿入片のこのような部分に係合部として係合爪を形成することで係合部は連結枠の下面に係合可能となる。
また、第６の手段では第１〜第５のいずれかの手段に加え、前記係合部は前記連結部本体の前記挿入片と対面する側の下方位置に形成された係合爪であることをその要旨とする。
これも係合部の具体的な構成であって、連結部本体のこのような位置に係合部として係合爪を形成することで係合部は連結枠の下面に係合可能となる。 Further, in the fourth means, in addition to any one of the first to third means, the uppermost position with respect to the lowermost position of the elongated hole is disposed at a position far from the insertion piece. Is the gist.
As a result, when the connecting part body is lowered while the insertion piece is inserted into the connection frame, the connection part body approaches the connection frame, and rattling between the insertion piece and the connection frame can be suppressed. It becomes. Furthermore, when the engaging portion is formed in the connecting portion main body, the connecting portion main body is lowered and simultaneously brought close to the connecting frame, so that the engaging portion can be arranged at the lower surface position of the connecting frame.
Further, in the fifth means, in addition to any one of the first to fourth means, the engaging portion is formed on a side surface portion of the insertion piece protruding below the connecting frame when the connecting portion is connected. The gist is that it is an engaging claw.
This is a specific configuration of the engaging portion. By forming an engaging claw as an engaging portion in such a portion of the insertion piece, the engaging portion can be engaged with the lower surface of the connecting frame.
Further, in the sixth means, in addition to any one of the first to fifth means, the engaging portion is an engaging claw formed at a lower position on the side of the connecting portion main body facing the insertion piece. Is the gist.
This is also a specific configuration of the engaging portion. By forming an engaging claw as an engaging portion at such a position of the connecting portion main body, the engaging portion can be engaged with the lower surface of the connecting frame.

本発明によれば、筋交を配置する際に上側の連結部分についてくさび片の打ち込みを不要にし、作業効率を向上させることができる。   According to the present invention, it is not necessary to drive a wedge piece for the upper connecting portion when arranging the braces, and work efficiency can be improved.

As shown in FIG. 1, the swing plate 20 is inserted into a male screw 25 as a swing shaft in a state where the through hole 22 of the base plate 21 is matched with the long hole 17 of the both plate bodies 14, and between the both plate bodies 14. Suspended and supported. The rocking plate 20 is a nylon nut (a nylon ring with a locking function is provided on the inner periphery) with a washer 26 interposed from the other plate 14 side to a male screw 25 inserted from the other plate 14 side. The nut (27 fitted) 27 is screwed and cannot be removed.

図２、図５及び図６に示すように、揺動プレート２０は揺動軸としての雄ネジ２５が長孔１７に沿って（つまり長孔１７に案内されて）移動することが可能となる。雄ネジ２５が長孔１７の最上方位置に配置された場合には図２及び図６に示すように板体１４に対して相対的に揺動プレート２０は最も上昇した位置に配置される。一方、雄ネジ２５が長孔１７の最下方位置に配置された場合には図５に示すように板体１４に対して相対的に揺動プレート２０は最も下降した位置に配置される。揺動プレート２０が板体１４に対して相対的に最も上昇した位置にある場合には図６に示すように当接ブロック１８の第１の当接面１８ａとベースプレート２１の第２の当接面２１ａがちょうどぴったりと面着されることとなる。そして、挿入バー２２は板体１４に対して最も接近した状態とされる。この状態では雄ネジ２５を中心に図上時計回り方向に回動させようとしても面同士が当接して揺動プレート２０は回動することはできない。
一方、揺動プレート２０が板体１４に対して相対的に最も下降した位置にある場合には図５に示すように当接ブロック１８の第１の当接面１８ａからベースプレート２１の第２の当接面２１ａは斜め前方下方にずれた位置に移動することとなって、雄ネジ２５を中心に図上時計回り方向に回動させようとする場合に揺動プレート２０の進行方向に余裕（空間）ができるため、揺動可能となる。
正面視において揺動プレート２０は両板体１４間に吊り下げ支持された状態でベースプレート２１が張り出し部１５と概ね重複状に配置され、挿入バー２２は最も板体１４側に接近した状態（雄ネジ２５が長孔１７の最上方位置に配置された場合）で図２及び図６に示すようにその係合爪２３が板体１４側の係合片１６と一部重複位置関係とされる。 As shown in FIGS. 2, 5, and 6, the rocking plate 20 can move a male screw 25 as a rocking shaft along the long hole 17 (that is, guided by the long hole 17). . When the male screw 25 is disposed at the uppermost position of the long hole 17, the swing plate 20 is disposed at the most elevated position relative to the plate body 14 as shown in FIGS. 2 and 6. On the other hand, when the male screw 25 is disposed at the lowermost position of the long hole 17, the swing plate 20 is disposed at the lowest position relative to the plate body 14 as shown in FIG. 5. When the swinging plate 20 is at the most elevated position relative to the plate member 14, the first contact surface 18a of the contact block 18 and the second contact of the base plate 21 as shown in FIG. The surface 21a is just exactly worn. Then, the insertion bar 22 is in a state closest to the plate body 14. In this state, even if an attempt is made to rotate the male screw 25 in the clockwise direction in the drawing, the surfaces come into contact with each other and the swing plate 20 cannot rotate.
On the other hand, when the swing plate 20 is at the lowest position relative to the plate member 14, the second contact of the base plate 21 from the first contact surface 18a of the contact block 18 as shown in FIG. The contact surface 21a moves to a position shifted diagonally forward and downward, so that it is possible to move the rocking plate 20 in the traveling direction when it is intended to rotate around the male screw 25 in the clockwise direction in FIG. Since the space is created, it can swing.
In the front view, the swing plate 20 is suspended and supported between the two plate bodies 14 and the base plate 21 is disposed so as to substantially overlap the overhanging portion 15, and the insertion bar 22 is closest to the plate body 14 side (male). When the screw 25 is disposed at the uppermost position of the long hole 17), as shown in FIGS. 2 and 6, the engagement claw 23 is partially overlapped with the engagement piece 16 on the plate body 14 side. .

次に、足場用補強部材を設置した際に下側に配置される第２の連結部１２について説明する。
第２の連結部１２の連結具本体１１は２枚の同形状の板体３１より構成されている。以下の第１の連結部１１の説明では図４における右方を前方として説明する。また、図４における第２の連結部１２の配置における上下方向をもって垂直方向とする。
一対の板体３１は所定の間隔を有して鏡像関係となるように向かい合わせに、かつ平行に配置されている。両板体３１の前方には連結バー３２が固着されており、両板体３１の間であって連結バー３２後方にはくさび片３３が遊嵌されている。板体３１間の空間の内の上部寄りには筋交１０のプレスされた先端部１０ａが挿入され溶着固定されている。すなわち、連結バー３２の肉厚と筋交１０の先端部１０ａの肉厚がちょうど両板体３１の間隔に相当する。両板体３１の上半身部分は前方に長く張り出しており、くさび片３３を両側から挟むくさび片挿入部３４とされている。くさび片通過部３４の下側後方寄りは切り欠き状にえぐられて棚部３５が形成されている。 Next, the 2nd connection part 12 arrange | positioned below when installing the reinforcement member for scaffolds is demonstrated.
The connector main body 11 of the second connecting part 12 is composed of two plate bodies 31 having the same shape. In the following description of the first connecting portion 11, the right side in FIG. Further, the vertical direction in the arrangement of the second connecting portions 12 in FIG.
The pair of plate bodies 31 are arranged face-to-face and in parallel so as to have a mirror image relationship with a predetermined interval. A connecting bar 32 is fixed in front of both plate bodies 31, and a wedge piece 33 is loosely fitted between the two plate bodies 31 and behind the connecting bar 32. Near the upper part of the space between the plate bodies 31, a pressed tip 10a of the brace 10 is inserted and fixed by welding. That is, the thickness of the connecting bar 32 and the thickness of the distal end portion 10 a of the brace 10 correspond to the distance between both plate bodies 31. The upper body portions of the two plate bodies 31 extend long forward, and serve as wedge piece insertion portions 34 that sandwich the wedge pieces 33 from both sides. A shelf portion 35 is formed by cutting out the lower rear side of the wedge piece passage portion 34 in a notch shape.

くさび片３３は板状に形成されており、基部側には張り出し部を有する頭部３８が形成されている。頭部３８はハンマー等でくさび片３３を打ち込む際の打点となるとともに、この頭部３８が両板体３１の上端部分に干渉することとなるため、連結具本体１１からの下方への脱落が防止されている。くさび片３３の先端寄り側方には突起３６が突設されている。そのため、くさび片３３は上方に持ち上げた際にこの突起３６が一方の板体３１（図３では手前側）のくさび片挿入部３４の下端部分に干渉することとなるため、連結具本体１１のくさび片挿入部３４から上方に抜き取ることができなくなっている。くさび片３３の下端よりも若干上方位置には板体３１方向に向かって突出した係合爪３７が形成されている。   The wedge piece 33 is formed in a plate shape, and a head portion 38 having an overhanging portion is formed on the base side. The head 38 serves as a hitting point when the wedge piece 33 is driven with a hammer or the like, and the head 38 interferes with the upper end portions of the two plate bodies 31. It is prevented. A protrusion 36 is provided on the side of the wedge piece 33 closer to the tip. Therefore, when the wedge piece 33 is lifted upward, this projection 36 interferes with the lower end portion of the wedge piece insertion portion 34 of one plate body 31 (front side in FIG. 3). The wedge piece insertion portion 34 cannot be extracted upward. At a position slightly above the lower end of the wedge piece 33, an engaging claw 37 protruding toward the plate body 31 is formed.

このように構成された足場用補強部材は足場材５０に形成されたた連結枠５１に対して連結されることとなる。足場材５０を縦材とし、足場材５０に対して梁部材と踏み板及び足場用補強部材等を組み合わせることで足場５５が構築される。尚、連結枠５１は梁部材を架設する際にも使用される。以下では足場用補強部材を連結することに特化して説明する。図７〜図９に示すように、水平方向での断面がチャンネル状となる連結枠５１がパイプ材より構成された足場材５０の外周に形成されている。連結枠５１は足場材５０の外周面に突設された上下に連通された枠体であって、対抗配置された一対の側板５１ａと両側板５１ａ間に懸架された前板５１ｂとより構成されている。一対の連結枠５１は１８０度対向する位置に配置されており、この一対の連結枠５１に対して上下方向にずれ、かつ９０度変位した位置に他の一対の連結枠５１が配置されている。すなわち四方に向いた連結枠５１が形成された連結ポイント５３が構成されている。このような連結ポイント５３が足場材５０には所定間隔で配置されている。   The scaffold reinforcing member configured as described above is connected to the connecting frame 51 formed on the scaffold member 50. The scaffold 55 is constructed by using the scaffold member 50 as a vertical member and combining the scaffold member 50 with a beam member, a footboard, a scaffold reinforcing member, and the like. The connecting frame 51 is also used when installing a beam member. Below, it demonstrates focusing on connecting the reinforcement member for scaffolds. As shown in FIGS. 7 to 9, a connecting frame 51 having a channel-like cross section in the horizontal direction is formed on the outer periphery of a scaffold material 50 made of a pipe material. The connecting frame 51 is a vertically extending frame projecting on the outer peripheral surface of the scaffold member 50, and includes a pair of side plates 51a opposed to each other and a front plate 51b suspended between the side plates 51a. ing. The pair of connection frames 51 are arranged at positions facing each other by 180 degrees, and the other pair of connection frames 51 are arranged at positions shifted vertically by 90 degrees with respect to the pair of connection frames 51. . That is, the connection point 53 in which the connection frame 51 facing in all directions is formed. Such connection points 53 are arranged on the scaffold member 50 at predetermined intervals.

次に、このような足場用補強部材を足場５５（足場材５０）に取り付ける際の取り付け工程について説明する。
この足場用補強部材は必ず上方側に配置される第１の連結部１１側から先に、ある足場材５０のある連結枠５１に対して連結し、しかる後に隣接配置された足場材５０の下方位置（斜め下方位置）に形成された連結枠５１に連結するようにするものである。
まず、作業者は第１の連結部１１を図５のように雄ネジ２５が長孔１７の最下方位置に配置されるようにする。この状態では揺動プレート２０は仮想線の最も板体１４に接近した位置から実線のような揺動位置（実際にはこの図示以上に大きく揺動することは可能である）に自在に揺動させることができる。ここでは連結枠５１への上方からの挿入をしやすくするするために筋交１０を若干寝かし気味に保持し、揺動プレート２０を相対的に板体１４から離間する方向に揺動させて両者間の間隔を開けるようにすることがよい。この保持状態で揺動プレート２０の挿入バー２２を連結枠５１の上方位置から下降させていく進入に従って挿入バー２２の基部寄りの第３の当接面２１ｂが連結枠５１の上端に当接することとなる。挿入に伴って作業者は揺動プレート２０が図５の仮想線の位置となるように筋交１０を回動させていき、あわせて筋交１０を斜め下方、つまり筋交１０の長手方向に沿って下方に引っ張るようにする。すると、第１の連結部１１及び筋交１０は揺動プレート２０のみが連結枠５１に載置されて残った状態で、それ以外の全体が長孔１７分だけ斜め下方に移動することとなる。すなわち、図２及び図６の雄ネジ２５が長孔１７の最上方位置に配置された状態である。そして、板体１４の張り出し部１５の下面が第３の当接面２１ｂに代わって連結枠５１の上端に当接することとなる。また、挿入バー２２の下方位置に形成された係合爪２３と板体１４下方位置に形成された係合片１６がいずれも平面視において連結枠５１と重複する位置に配置されることとなる。 Next, an attachment process when attaching such a reinforcing member for scaffold to the scaffold 55 (scaffold material 50) will be described.
This reinforcing member for scaffolding is connected to the connecting frame 51 with a certain scaffolding material 50 first from the first connecting part 11 side arranged on the upper side, and then below the scaffolding material 50 arranged adjacently. It connects with the connection frame 51 formed in the position (diagonal downward position).
First, the operator places the first connecting portion 11 so that the male screw 25 is disposed at the lowest position of the long hole 17 as shown in FIG. In this state, the swing plate 20 freely swings from the position closest to the plate 14 of the imaginary line to a swing position such as a solid line (actually, it can swing larger than this figure). Can be made. Here, in order to facilitate the insertion into the connecting frame 51 from above, the bracing 10 is held slightly asleep, and the swinging plate 20 is swung relatively away from the plate body 14 to both. It is better to leave a gap between them. In this holding state, the third contact surface 21b near the base of the insertion bar 22 comes into contact with the upper end of the connection frame 51 as the insertion bar 22 of the swing plate 20 is lowered from the upper position of the connection frame 51. It becomes. With the insertion, the operator rotates the bracing 10 so that the swing plate 20 is located at the position of the phantom line in FIG. 5, and also moves the bracing 10 diagonally downward, that is, in the longitudinal direction of the bracing 10. Pull it down along. Then, the first connecting portion 11 and the brace 10 are left with only the rocking plate 20 placed on the connecting frame 51, and the rest of the first connecting portion 11 and the brace 10 move obliquely downward by the long hole 17 minutes. . That is, the male screw 25 of FIGS. 2 and 6 is in a state of being arranged at the uppermost position of the long hole 17. And the lower surface of the overhang | projection part 15 of the board 14 will contact | abut to the upper end of the connection frame 51 instead of the 3rd contact surface 21b. Further, the engaging claw 23 formed at the lower position of the insertion bar 22 and the engaging piece 16 formed at the lower position of the plate body 14 are both arranged at a position overlapping the connecting frame 51 in plan view. .

この状態で図６に示すようにスライド移動した揺動プレート２０は第２の当接面２１ａがストッパ１８の第１の当接面１８ａとちょうどぴったりと面着されてしまうので揺動プレート２０がその挿入バー２２が板体１４から離間する方向に揺動することはない（つまり、挿入バー２２が開かない）。図７及び図９に示すように第１の連結部１１が上側の連結枠５１に連結された状態で上方への引き抜き力が働いても挿入バー２２が開かず、挿入バー２２側の係合爪２３と板体１４側の係合片１６が連結枠５１の下端面に干渉することとなるため第１の連結部１１が連結枠５１から脱落してしまうことはない。
以上のような工程で第１の連結部１１をある連結枠５１に連結した後に、続いて下方位置に形成された連結枠５１に第２の連結部１２を連結する。
図４に示すように、まずくさび片３３を棚部３５上に載置する。そして、連結バー３２の連結枠５１の上方から挿入する。この状態では第２の連結部１２は連結枠５１に固定されておらず仮止め状態である。次いで、くさび片３３を棚部３５の上から降ろすとくさび片３３は自重で落下する。次いで、くさび片３３をハンマー等で打ち込むことでくさび片３３を連結枠５１に対して押しつけることとなり、第２の連結部１２はしっかりと連結枠５１に固定される。図９は２セットの足場用補強部材を交差させるように足場５５に取り付けた状態である。
足場用補強部材を取り外す場合には、上記とは逆に、まずハンマー等で第２の連結部１２のくさび片３３の下端部を叩き、これを緩めてくさび片３３を一旦棚３５の上に載置する。そして、筋交１０を持って連結バー３２を連結枠５１から抜き、第２の連結部１２を外す。
次いで、筋交１０をを斜め上方、つまり筋交１０の長手方向に沿って上方に押すようにする。これによって、第１の連結部１１は挿入バー２２が図２及び図６の状態から図５の位置に変位することとなり、固定状態が解除されるため足場用補強部材を足場５５（足場材５０）から取り外すことができる。 In this state, the swing plate 20 slid and moved as shown in FIG. 6 has its second contact surface 21 a just exactly flush with the first contact surface 18 a of the stopper 18. The insertion bar 22 does not swing in a direction away from the plate 14 (that is, the insertion bar 22 does not open). 7 and 9, the insertion bar 22 does not open even when an upward pulling force is applied in a state where the first coupling portion 11 is coupled to the upper coupling frame 51, and the insertion bar 22 side is engaged. Since the nail | claw 23 and the engaging piece 16 by the side of the board 14 interfere with the lower end surface of the connection frame 51, the 1st connection part 11 does not drop from the connection frame 51. FIG.
After connecting the 1st connection part 11 to a certain connection frame 51 by the above processes, the 2nd connection part 12 is connected with the connection frame 51 formed in the downward position succeedingly.
As shown in FIG. 4, the wedge piece 33 is first placed on the shelf portion 35. And it inserts from the upper direction of the connection frame 51 of the connection bar 32. In this state, the second connecting portion 12 is not fixed to the connecting frame 51 and is in a temporarily fixed state. Next, when the wedge piece 33 is lowered from the shelf 35, the wedge piece 33 falls by its own weight. Next, the wedge piece 33 is driven against the connecting frame 51 by driving the wedge piece 33 with a hammer or the like, and the second connecting portion 12 is firmly fixed to the connecting frame 51. FIG. 9 shows a state in which two sets of scaffold reinforcing members are attached to the scaffold 55 so as to cross each other.
When removing the reinforcing member for scaffolding, contrary to the above, first, the lower end portion of the wedge piece 33 of the second connecting portion 12 is hit with a hammer or the like and loosened to temporarily place the wedge piece 33 on the shelf 35. Place. Then, holding the bracing 10, the connecting bar 32 is pulled out of the connecting frame 51 and the second connecting portion 12 is removed.
Next, the bracing 10 is pushed diagonally upward, that is, upward along the longitudinal direction of the bracing 10. As a result, the insertion bar 22 is displaced from the state of FIGS. 2 and 6 to the position of FIG. 5 in the first connecting portion 11, and the fixed state is released, so that the scaffold reinforcing member is used as the scaffold 55 (scaffold material 50 ) Can be removed.

以上のように構成することで実施の形態１の足場用補強部材では次のような効果が奏される。
（１）筋交を備えた足場用補強部材において自分よりも上方位置にある連結枠５１に対しては第１の連結部１１を連結する際にくさび片を打ち込む必要がなくなるため、上下それぞれの位置で作業する必要がなくなる。つまり、作業者は第２の連結部１２のくさび片３３を打ち込むために下側だけで作業することが可能となるため、上側の作業が省略されることとなり作業効率がアップする。
（２）くさび片が不要となるため第１の連結部１１の部材点数が少なくなり、軽量化やコストダウンに貢献する。
（３）第１の連結部１１が連結された状態で上方への引き抜き力が働いても挿入バー２２が開かず、挿入バー２２側の係合爪２３と板体１４側の係合片１６の両方が連結枠５１の下端面に干渉することとなるため第１の連結部１１の連結枠５１からの脱落が確実に防止される。
（４）筋交１０を斜め下方に引っ張ることで、第１の連結部１１の板体１４は下動すると同時に連結枠５１に接近することとなる。つまり、板体１４側の係合片１６は揺動プレート２０が板体１４に対して相対的に上方位置にある場合には連結枠５１から離間した位置に配置され、下動して初めて連結枠５１と干渉可能な接近した位置に配置されるようになっており、挿入バー２２を連結枠５１に挿入させる際に板体１４や係合片１６が挿入の邪魔になりにくいようになっている。 With the configuration as described above, the scaffold reinforcing member of Embodiment 1 has the following effects.
(1) Since there is no need to drive a wedge piece when connecting the first connecting portion 11 to the connecting frame 51 in a position higher than the self in the reinforcing member for scaffolding having a brace, No need to work in position. That is, since the operator can work only on the lower side in order to drive the wedge piece 33 of the second connecting portion 12, the upper work is omitted and the work efficiency is improved.
(2) Since the wedge piece is unnecessary, the number of members of the first connecting portion 11 is reduced, which contributes to weight reduction and cost reduction.
(3) Even if an upward pulling force is applied in a state where the first connecting portion 11 is connected, the insertion bar 22 does not open, and the engagement claw 23 on the insertion bar 22 side and the engagement piece 16 on the plate 14 side Since both of them interfere with the lower end surface of the connecting frame 51, the first connecting portion 11 is reliably prevented from falling off the connecting frame 51.
(4) By pulling the bracing 10 diagonally downward, the plate 14 of the first connecting portion 11 moves downward and approaches the connecting frame 51 at the same time. That is, the engagement piece 16 on the plate body 14 side is disposed at a position separated from the connection frame 51 when the swing plate 20 is in an upper position relative to the plate body 14, and is not connected until it moves downward. It is arranged at a close position where it can interfere with the frame 51, and the plate body 14 and the engagement piece 16 are less likely to obstruct insertion when the insertion bar 22 is inserted into the connecting frame 51. Yes.

（実施の形態２）
実施の形態２では作業者が下側位置にいて自分よりも上方位置にある連結枠５１に対して第１の連結部１１を連結させることができる、という本発明の特性を利用して筋交１０による補強と同時に先行手すりを設置する実施の形態について説明する。上記実施の形態１と同様の構成については図面に同じ番号を付することで詳しい説明は省略する。
図１０及び図１１に示すように実施の形態２の足場用補強部材では実施の形態１の筋交１０の両端に第１の連結部１１と第２の連結部１２を固着した筋交部材７１を２セット用意する。両筋交部材７１の第１の連結部１１間にはパイプ材よりなる水平材７２が継ぎ手プレート７３を介して溶接によって固着されている。水平材７２の長手方向は第１の連結部１１の挿入バー２２の延出方向（つまり垂直方向）に対して直交している。 (Embodiment 2)
In the second embodiment, the bracing is performed by utilizing the characteristic of the present invention that the first connecting portion 11 can be connected to the connecting frame 51 located at the lower position and higher than the operator. An embodiment in which a preceding handrail is installed at the same time as reinforcement by 10 will be described. About the structure similar to the said Embodiment 1, detailed description is abbreviate | omitted by attaching | subjecting the same number to drawing.
As shown in FIGS. 10 and 11, in the reinforcing member for scaffolding of the second embodiment, the bracing member 71 in which the first connecting portion 11 and the second connecting portion 12 are fixed to both ends of the bracing 10 of the first embodiment. Prepare two sets. A horizontal member 72 made of a pipe material is fixed between the first connecting portions 11 of the two bracing members 71 through a joint plate 73 by welding. The longitudinal direction of the horizontal member 72 is orthogonal to the extending direction (that is, the vertical direction) of the insertion bar 22 of the first connecting portion 11.

このような構成の足場用補強部材では、上側の連結枠５１に対して第１の連結部１１を連結させる際には挿入バー２２が水平材７２によって動きが規制されているため、挿入バー２２と板体１４とを離間させる際には板体１４側を揺動させる必要がある。他の操作については上記実施の形態１と同様である。すなわち、隣接した足場材５０の同じ高さのある連結枠５１に対して同時に挿入バー２２を上方から挿入し、その後筋交部材７１の筋交１０を交差させ、上記実施の形態１と同様に筋交１０を斜め下方に引っ張り、第２の連結部１２を下側の連結枠５１に連結するようにする。このように構成することで上記実施の形態１の効果に加え、作業者は下方位置にいてこれから足場を上方に組み上げて行く際の先行手すりを設置することができる。   In the reinforcing member for scaffolding having such a configuration, when the first connecting portion 11 is connected to the upper connecting frame 51, the movement of the insertion bar 22 is restricted by the horizontal member 72. When separating the plate 14 and the plate 14, it is necessary to swing the plate 14 side. Other operations are the same as those in the first embodiment. That is, the insertion bar 22 is simultaneously inserted from above into the connecting frame 51 having the same height of the adjacent scaffold 50, and then the bracing 10 of the bracing member 71 is crossed, as in the first embodiment. The bracing 10 is pulled obliquely downward so that the second connecting portion 12 is connected to the lower connecting frame 51. By configuring in this way, in addition to the effect of the first embodiment, the operator can install a handrail at the lower position and then assemble the scaffold upward.

・板体１４が下動した際に連結枠５１方向に接近しないように長孔１７を傾斜させずに構成するとことも可能である。
・ストッパ部材（当接ブロック１８）の形状や位置について上記は一例である。
・長孔１７の形状は上記に限定されない。
・揺動軸の構成について上記実施の形態では雄ネジ２５とナイロンナット２７で構成していたが、他の手段（例えば、リベット留め）を使用して揺動プレート２０を吊り下げ支持するようにしてもよい。
・上記実施の形態では挿入バー２２側の係合爪２３と板体１４側の係合片１６の両方を備える構成であったが、いずれか一方だけでもよい。
・連結具本体１１は一対の板体３１でなくともよい。例えば、１枚の板体であっても打ち込んだくさび部材が脱落せず、連結具を固定させるための当接部があれば足る。もちろん、形態として板体である必要はない。
その他、材質は不問である、部材の接合は溶接以外の手段でもよい等本発明の趣旨を逸脱しない態様で実施することは自由である。 In addition, this invention can also be embodied in the aspect changed as follows.
It is also possible to configure the long hole 17 without inclining so that the plate body 14 does not approach in the direction of the connecting frame 51 when the plate member 14 moves down.
The above is an example of the shape and position of the stopper member (contact block 18).
-The shape of the long hole 17 is not limited to the above.
-Concerning the structure of the swinging shaft In the above embodiment, the swinging shaft 20 is composed of the male screw 25 and the nylon nut 27. However, the swinging plate 20 is suspended and supported using other means (for example, riveting). May be.
In the embodiment described above, the engaging claw 23 on the insertion bar 22 side and the engaging piece 16 on the plate body 14 side are both provided, but either one may be used.
The connector main body 11 does not have to be a pair of plate bodies 31. For example, even if it is a single plate body, the wedge member that has been driven in does not fall off, and it is sufficient if there is a contact portion for fixing the coupling tool. Of course, the plate need not be a plate.
In addition, the material is not required, and it is free to carry out in a mode that does not depart from the gist of the present invention, such as joining of members may be means other than welding.
