Description

本発明は、建築足場を構築するために使用される布材やブラケット等の梁・筋交い部材、梁・筋交い部材の支柱側の緊結部への連結構造及び連結方法に関するものである。 TECHNICAL FIELD The present invention relates to a beam and bracing member such as a cloth material and a bracket used for constructing a building scaffold, and a connection structure and a coupling method of a beam and a bracing member to a column-side binding portion.

一般に建築現場等に仮設される建築足場は、所定の間隔で立設された支柱と、梁部材（布材、ブラケット等）とを縦横に組み合わせ、梁部材に踏み板を架設することで基本的骨格が構築されている。作業者はこの踏み板上で作業をし、また踏み板上を移動する。建築足場における梁部材の一例として特許文献１及び２を挙げる。
例えば特許文献１の図１、図３及び図８等に示すように、架設材としての横架部１５の両端部にくさび式連結部のくさび片としてのフック部１４がその先端が側方に向かって突設されるように固定されて梁部材が構成されている。特許文献２でも同様に図３に示すように架設材としての腕木３の両端部にくさび式連結部のくさび片としてのくさび９が側方に向かって突設されるように固定されて梁部材が構成されている。
これら梁部材は隣り合って配置された特許文献１の図２に示すような支柱において対応する緊結部としての２つの緊結ホルダーに対してそれぞれくさび片（フック部１４、くさび９）を上方から挿入させ、ハンマー等の道具によって叩き込んで固定するようにしている。 In general, building scaffolds temporarily set up at construction sites, etc., have a basic skeleton by combining struts erected at predetermined intervals and beam members (cloth materials, brackets, etc.) vertically and horizontally, and erection steps on the beam members. Has been built. The worker works on the tread board and moves on the tread board. Patent documents 1 and 2 are mentioned as an example of a beam member in a building scaffold.
For example, as shown in FIGS. 1, 3, and 8 of Patent Document 1, hook portions 14 as wedge pieces of a wedge-type connecting portion are provided at both ends of a laterally extending portion 15 as a construction material, and the tip thereof is lateral. The beam member is configured to be fixed so as to protrude toward the front. Similarly, in Patent Document 2, as shown in FIG. 3, a beam member is fixed so that a wedge 9 as a wedge piece of a wedge-type connecting portion protrudes laterally at both ends of a brace 3 as a construction material. Is configured.
These beam members are inserted adjacently into the two fastening holders as the corresponding fastening parts in the support columns as shown in FIG. 2 of Patent Document 1 from the upper side, respectively (hook part 14 and wedge 9). It is fixed by hitting with a tool such as a hammer.

このように、従来の梁部材では作業者は、必ずくさび片を緊結ホルダーに対してしっかりと強い力で叩き込む作業が必要となる。この作業は時間と体力が必要となる。そのため、従来からこのような叩き込み作業を軽減させることが求められていた。また、梁部材だけでなく両端にくさび片が形成された筋交い部材についても同じ課題が生じていた。
本発明は、上記課題を解決するためのものである。その目的は、くさび片を強く叩き込む作業をしなくとも梁・筋交い部材の連結部を支柱側の緊結部に固定することができる梁・筋交い部材、梁・筋交い部材の支柱側の緊結部への連結構造及び連結方法を提供することにある。 As described above, in the conventional beam member, the operator is required to strike the wedge piece against the binding holder with a strong force. This work requires time and physical strength. Therefore, conventionally, it has been required to reduce such a driving work. Moreover, the same problem has arisen not only for the beam member but also for the bracing member in which wedge pieces are formed at both ends.
The present invention is for solving the above-mentioned problems. The purpose is to fix the connecting part of the beam and bracing member to the tying part on the column side without the work of striking the wedge piece strongly, to the tying part on the column side of the beam and bracing member It is to provide a connection structure and a connection method.

上記課題を解決するために、第１の手段として、上下方向に連通する係合孔を有する鍔状の緊結部が外周に形成された支柱を複数用意し、前記支柱を隣り合って立設配置した状態で、隣接する前記支柱の前記緊結部間に連結させられる梁・筋交い部材において、架設材と、同架設材の両端に形成された連結部を備え、少なくとも一方の前記連結部は前記緊結部側の前記係合孔に対して上方から挿入され前記緊結部の下方に突出する第１の挿入部が形成された連結部本体と、同連結部本体に対して上下動可能に支持され、前記第１の挿入部に対して隣接して配置され前記係合孔に対して上方から挿入される第２の挿入部とを備え、前記第２の挿入部は前記第１の挿入部側に向いた面が上下方向で凸となるように湾曲して構成され上下動する際にその湾曲面形状に略沿って移動し、前記第２の挿入部が前記第１の挿入部に対して相対的に上方側に移動した際に前記第２の挿入部の下端側は前記第１の挿入部に接近し、前記第２の挿入部が下方側に移動した際に前記第２の挿入部の下端側は前記第１の挿入部から離間するようにした。 In order to solve the above-mentioned problem, as a first means, a plurality of struts each having a hook-like tightening portion having an engagement hole communicating in the up-down direction are formed on the outer periphery, and the struts are arranged side by side. In this state, the beam and bracing member that is connected between the tightening portions of the adjacent struts includes a construction material and connection portions formed at both ends of the construction material, and at least one of the connection portions is the tightness connection. A connecting portion main body formed with a first insertion portion that is inserted from above into the engagement hole on the part side and protrudes below the binding portion, and is supported to be movable up and down with respect to the connecting portion main body, A second insertion portion that is disposed adjacent to the first insertion portion and is inserted into the engagement hole from above, and the second insertion portion is disposed on the first insertion portion side. When the up and down movement is configured and curved so that the facing surface is convex in the vertical direction When the second insertion portion moves relatively upward with respect to the first insertion portion, the lower end side of the second insertion portion is moved toward the first insertion portion. When the second insertion portion moves downward, the lower end side of the second insertion portion is separated from the first insertion portion.

このような構成の梁・筋交い部材とすることで、くさび片を叩き込む作業をしなくとも第２の挿入部が緊結部の係合孔内に落下すると第２の挿入部の下端側は第１の挿入部から離間した位置、言い換えれば外方に張り出すようになるため、第２の挿入部の下端側が連結部を上動させようとする場合に第２の挿入部が緊結部と干渉することとなって、必ずしも第２の挿入部を叩き込まなくとも、緊結部から連結部が外れてしまうことがない。これによって、従来のようなくさび片を叩き込む作業が不要となり作業効率がアップすることとなる。
ここで、第２の挿入部は叩かなくとも自重で緊結部と干渉する位置に下動するわけであるが、実際においては念のために軽く叩いてよりしっかりと連結部を固定するような作業をすることがあり、本発明はこのような付随的な打ち込みまでも排除する意図ではない。また、第２の挿入部が緊結部に食い込むこともあるため、連結部の取り外しの際には第２の挿入部を下から上に向かって叩くことはありうる。
第１の挿入部が連結部本体と一体化しており、第２の挿入部が上下動できるのであれば具体的な形状は適宜変更可能である。また、本発明にかかる連結部は架設材の両側にあっても片方のみであってもよい。 By using the beam and bracing member having such a configuration, the lower end side of the second insertion portion is the first side when the second insertion portion falls into the engagement hole of the tightening portion without performing the operation of striking the wedge piece. The second insertion portion interferes with the tightening portion when the lower end side of the second insertion portion tries to move the connecting portion upward, because the second insertion portion protrudes outward from the position away from the insertion portion. In other words, the connecting portion does not necessarily come off from the binding portion without necessarily hitting the second insertion portion. This eliminates the need to strike the wedge pieces as in the prior art and increases the work efficiency.
Here, the second insertion part moves down to a position where it interferes with the tightening part by its own weight without hitting, but in actuality, it is a work to fix the connecting part more firmly by tapping lightly just in case. The present invention is not intended to exclude even such incidental driving. In addition, since the second insertion portion may bite into the binding portion, the second insertion portion can be hit from the bottom upward when removing the connecting portion.
If the 1st insertion part is integrated with the connection part main part and the 2nd insertion part can move up and down, a concrete shape can be changed suitably. Moreover, the connection part concerning this invention may be in the both sides of a construction material, or may be only one side.

第２の手段として、前記第２の挿入部が上下動する際に案内手段によって案内されるようにした。
この構成によって第２の挿入部の上下動がスムーズとなる。案内手段としては、例えば第２の挿入部の内周面に外周と近似した湾曲面を形成し、その湾曲面が連結部本体側の突起に当接してスライド移動をする場合がある。そのような湾曲面を逆に連結部本体側に形成して第２の挿入部側に突起を設けるようにしてもよい。突起は１つでもよいが複数あることでより正確な案内が可能である。 As a second means, when the second insertion portion moves up and down, it is guided by the guide means.
With this configuration, the vertical movement of the second insertion portion becomes smooth. As the guide means, for example, there is a case where a curved surface approximate to the outer periphery is formed on the inner peripheral surface of the second insertion portion, and the curved surface comes into contact with the protrusion on the connecting portion main body side and slides. On the contrary, such a curved surface may be formed on the connecting portion main body side and a protrusion may be provided on the second insertion portion side. Although there may be only one protrusion, more accurate guidance is possible by having a plurality of protrusions.

第３の手段として、前記第２の挿入部が下方側に移動した位置で前記連結部本体から脱落しないように第１の保持手段に係合されて第１の位置で保持されるようにした。
このように保持されることで、第２の挿入部は上下動可能であり、かつ自重で下方向に移動しても連結部本体から脱落してしまうことがない。この位置は、連結部を上動させようとすると第２の挿入部が緊結部と干渉してしまう程度に第１の保持手段に対して第２の挿入部の下端が離間している距離でもある。
第４の手段として、前記第２の挿入部が上方側に移動した位置で前記連結部本体から脱落しないように第２の保持手段に係合されて第２の位置で保持されるようにした。
このように保持されることで、第２の挿入部は上下動可能であり、かつ上方に配置した位置で保持することができる。これによって第２の挿入部を一旦非挿入としたい他の作業、例えば連結部の緊結部からの取り外しのような作業をする際、連結部を緊結部から速やかに取り外しできるように第２の挿入部を一旦非挿入状態として保持しておくことが可能となる。 As a third means, the second insertion portion is engaged with the first holding means so as not to drop off from the connecting portion main body at the position where the second insertion portion moves downward, and is held at the first position. .
By being held in this way, the second insertion portion can move up and down, and even if it moves downward due to its own weight, the second insertion portion does not fall off the connecting portion main body. This position is a distance that the lower end of the second insertion portion is separated from the first holding means to the extent that the second insertion portion interferes with the tightening portion when the connection portion is moved upward. is there.
As a fourth means, the second insertion portion is engaged with the second holding means so as not to fall off from the connecting portion main body at the position where the second insertion portion moves upward, and is held at the second position. .
By being held in this manner, the second insertion portion can move up and down and can be held at a position disposed above. As a result, when the second insertion portion is temporarily non-inserted, for example, when the connection portion is removed from the tightening portion, the second insertion is performed so that the connection portion can be quickly removed from the tightening portion. It becomes possible to hold the part once in a non-inserted state.

第５の手段として、前記第２の挿入部が前記連結部本体に対して上方側に移動させた際に前記連結部本体側の部材と直接的又は間接的に干渉して前記連結部本体からの取り外しが不能とされているようにした。
第２の挿入部が連結部本体から上方側に容易に取り外されないためである。直接的に干渉する場合とは第２の挿入部自身の形状によって連結部本体側と干渉する場合であり、間接的に干渉する場合とは他の部材を介在させて連結部本体側と干渉する場合である。 As a fifth means, when the second insertion portion is moved upward with respect to the connecting portion main body, it directly or indirectly interferes with a member on the connecting portion main body side, and from the connecting portion main body. It was made impossible to remove.
This is because the second insertion portion is not easily removed upward from the connecting portion main body. The case of directly interfering is the case of interfering with the connecting part main body side due to the shape of the second insertion part itself, and the case of indirect interference is interfering with the connecting part main body side through another member. Is the case.

第６の手段として、前記第２の挿入部は前記第１の挿入部に対して相対的に上方側に移動した際に重心が架設材側に移動するようにした。
このような構成であると、湾曲した第２の挿入部は第１の挿入部に対して相対的に上方側に移動することで重心が架設材側（後ろ寄り）となって、架設材方向に倒れやすくなるため、第２の挿入部が挿入部に対して相対的に上方側に移動した際に第２の挿入部の下端側は第１の挿入部に接近しやすくなる。また、このような作用を助長するため上方側をより重く構成することがよい。また、上記のような第２の保持手段によって係合させる場合もこのような相対的な第２の挿入部の移動によって架設材方向に倒れやすいことを利用して行うことがよい。 As a sixth means, the center of gravity moves to the construction material side when the second insertion portion moves upward relative to the first insertion portion.
With such a configuration, the curved second insertion part moves upward relative to the first insertion part, so that the center of gravity becomes the construction material side (backward), and the construction material direction Therefore, when the second insertion portion moves upward relative to the insertion portion, the lower end side of the second insertion portion is likely to approach the first insertion portion. Moreover, in order to promote such an effect | action, it is good to comprise an upper side more heavily. Further, when engaging with the second holding means as described above, it is preferable to make use of the fact that the relative movement of the second insertion portion tends to cause the body to fall in the direction of the construction material.

第７の手段として、第１〜第６のいずれかの手段に記載の前記梁・筋交い部材を使用した前記緊結部に対する連結構造であって、前記連結部の前記緊結部への装着状態において、前記連結部は前記挿入部及び前記第２の挿入部が前記緊結部の前記係合孔に挿入された状態で前記緊結部上に保持され、前記第１の挿入部及び前記第２の挿入部の前記緊結部の下方に突出する部分の前後幅は前記緊結部の前記係合孔の前後幅よりも大きくなる部分を有し、前記第２の挿入部は前記緊結部に対して前記第２の挿入部を上方側に移動させることで干渉する位置に配置されるようにした。
このような構造であると、自重で落下した第２の挿入部が外方に張り出して第１の挿入部及び第２の挿入部の緊結部の下方に突出する部分の前後幅が緊結部の係合孔の前後幅よりも大きくなるため、その状態で連結部を上方に移動させても第２の挿入部が干渉して外すことができなくなる。これによって、従来のようなくさび片を叩き込む作業が不要となり作業効率がアップすることとなる。
第８の手段として第７の手段において、前記第１の挿入部及び前記第２の挿入部の前記緊結部の下方に突出する部分における前記緊結部の前記係合孔の前後幅よりも大きくなる前後幅の部分とは、前記挿入部の下端位置における前後幅の部分であるようにした。つまり、第２の挿入部の部分を最も張り出させるという発想である。従って、この思想から最も外方に張り出す部分が最も下端でなくともよいこととなる。 As a seventh means, a connection structure to the tightening portion using the beam and bracing member according to any one of the first to sixth means, in the mounting state of the connection portion to the tightening portion, The connecting portion is held on the binding portion in a state where the insertion portion and the second insertion portion are inserted into the engagement holes of the binding portion, and the first insertion portion and the second insertion portion The front-rear width of the portion projecting downward of the tightening portion has a portion that is larger than the front-rear width of the engagement hole of the tightening portion, and the second insertion portion is the second portion with respect to the tightening portion. The insertion part is moved to the upper side so as to be arranged at the position where interference occurs.
With such a structure, the front and rear widths of the portion where the second insertion portion dropped due to its own weight protrudes outward and protrudes below the fastening portion of the first insertion portion and the second insertion portion are Since it becomes larger than the front-rear width of the engagement hole, the second insertion portion cannot be removed due to interference even if the connecting portion is moved upward in that state. This eliminates the need to strike the wedge pieces as in the prior art and increases the work efficiency.
In the seventh means as the eighth means, the first insertion portion and the second insertion portion are larger than the front-rear width of the engagement hole of the tightening portion in the portion protruding below the tightening portion. The front-rear width portion is the front-rear width portion at the lower end position of the insertion portion. That is, the idea is that the portion of the second insertion portion is projected most. Therefore, the portion that protrudes outward most from this idea may not be the lowest end.

第９の手段として、第１〜第６のいずれかの手段に記載の前記梁・筋交い部材を使用した前記緊結部に対する連結方法であって、前記第２の挿入部が下方側に移動した位置で前記連結部を前記緊結部の上方位置に配置し、前記挿入部を前記緊結部の前記係合孔に挿入させながら前記挿入部から離間した前記第２の挿入部を前記緊結部の上面に干渉させることで、前記第２の挿入部を相対的に前記第１の挿入部に対して上動させ、相対的な上動に伴って離間状態の前記第２の挿入部の下端側を前記挿入部に接近させ前記緊結部の上面との干渉を解除し、前記第２の挿入部の自重によって下動させて前記第２の挿入部を前記緊結部の前記係合孔に挿入させるようにした。
第１０の手段として第９の手段において、前記第２の挿入部が前記連結部の前記緊結部への装着状態において、前記緊結部に対して前記第２の挿入部を上動させることで干渉する位置に配置されるようにした。
このような方法であれば、前もって第２の挿入部をそのデフォルト位置として下方側に移動させておき、連結部を緊結部の上方位置から下降させるだけで、第１の挿入部を緊結部の係合孔に挿入させた後に若干の時間差をもって第２の挿入部が自重で係合孔に挿入され、なおかつ第２の挿入部の下端側が張り出すため、上方から強く叩き込む必要もない。これによって、単に連結部を緊結部に対して上方から接近させて第１の挿入部を挿入させるだけで自動的に第２の挿入部が落下して係合孔に挿入されることとなり、いわゆるワンタッチで固定できることとなり、作業効率がアップする。 As a ninth means, it is a connecting method to the binding part using the beam and bracing member according to any one of the first to sixth means, wherein the second insertion part has moved downward. The connecting portion is disposed above the binding portion, and the second insertion portion spaced from the insertion portion is inserted on the upper surface of the binding portion while the insertion portion is inserted into the engagement hole of the binding portion. By causing interference, the second insertion portion is moved upward relative to the first insertion portion, and the lower end side of the second insertion portion in the separated state is moved along the relative upward movement. Approaching the insertion portion, releasing interference with the upper surface of the binding portion, and moving downward by the weight of the second insertion portion to insert the second insertion portion into the engagement hole of the binding portion. did.
In the ninth means as the tenth means, the second insertion portion interferes by moving the second insertion portion upward relative to the tightening portion when the connecting portion is attached to the tightening portion. It was arranged at the position to do.
In such a method, the second insertion portion is moved downward as the default position in advance, and the first insertion portion of the binding portion is simply lowered by moving the connecting portion from the upper position of the binding portion. Since the second insertion portion is inserted into the engagement hole by its own weight with a slight time difference after being inserted into the engagement hole, and the lower end side of the second insertion portion protrudes, there is no need to strike it strongly from above. As a result, the second insertion portion is automatically dropped and inserted into the engagement hole by simply bringing the connection portion closer to the binding portion from above and inserting the first insertion portion. It can be fixed with a single touch, improving work efficiency.

And a substantially circular circular wall portion 21 arranged on the outer side perpendicular to the line. The distance between the side walls 18 and the diameter of the pipe material 12 substantially match each other, and the curve on the outer periphery of each side wall 18 substantially matches the curve on the outer periphery of the pipe material 12. An upper communication portion 19 and a lower communication portion 20 are formed in the upper and lower positions of the housing portion 15A, each opening in a square shape. As shown in FIG. 2, a pair of front and rear through holes 18a are formed near the upper communication portion 19 of both side walls 18 and closer to the tenon portion 15B, and a second holding means is formed between the two through holes 18a. A rivet 22 is driven in between the side walls 18. Long holes 23 extending in the vertical direction are formed in the side walls 18 at positions closer to the circular wall portion 21 than the through holes 18a. The long hole 23 is a through hole formed along the movement path of the movable piece 17 and is configured in a length and shape corresponding to the movement amount and the movement direction.

第１の挿入部としての挿入片１６は筐体部１５Ａから下方に向かって突出するように筐体部１５Ａと一体的に形成されている。図１〜図３に示すように、挿入片１６は横断面形状がチャンネル状とされた板体から構成された部材である。挿入片１６は筐体部１５Ａの円壁部２１とデザイン的に一体化した板部を構成する幅広板部２５と、幅広板部２５と直交するように幅広板部２５の幅方向の端部に一体形成された縁板部２４とから構成されている。幅広板部２５と円壁部２１の外面の面方向はパイプ材１２の延出方向に対して直交する方向とされている。縁板部２４は開放端面側が若干先細りになるようにテーパ状に構成されている。そのため、挿入片１６はくさびとしての機能を有する。
前後の側壁部１８に隣接した下部位置には水平板部２６が形成されている。水平板部２６は挿入片１６の縁板部２４とデザイン的に一体化してＬ字状の外観とされている。水平板部２６の水平な下面は当接面２６ａとされている。前後の水平部２５間には案内手段としての水平案内板２７が配設されている。水平案内板２７は前後の側壁部１８の間隔保持も兼ねている。前記下方連通部２０は前後の水平部２５と水平案内板２７と幅広板部２５とによって包囲された空間によって構成される。 The insertion piece 16 as the first insertion portion is formed integrally with the housing portion 15A so as to protrude downward from the housing portion 15A. As shown in FIGS. 1-3, the insertion piece 16 is a member comprised from the plate body by which the cross-sectional shape was made into channel shape. The insertion piece 16 includes a wide plate portion 25 constituting a plate portion integrated with the circular wall portion 21 of the housing portion 15A in design, and an end portion in the width direction of the wide plate portion 25 so as to be orthogonal to the wide plate portion 25. It is comprised from the edge-plate part 24 integrally formed. The surface directions of the outer surfaces of the wide plate portion 25 and the circular wall portion 21 are orthogonal to the extending direction of the pipe material 12. The edge plate portion 24 is configured to be tapered so that the open end face side is slightly tapered. Therefore, the insertion piece 16 has a function as a wedge.
A horizontal plate portion 26 is formed at a lower position adjacent to the front and rear side wall portions 18. The horizontal flat plate portion 26 is integrated with the edge plate portion 24 of the insertion piece 16 in design and has an L-shaped appearance. The horizontal lower surface of the horizontal plate portion 26 is a contact surface 26a. A horizontal guide plate 27 as a guide means is disposed between the front and rear horizontal portions 25. The horizontal guide plate 27 also serves to maintain the distance between the front and rear side wall portions 18. The lower communication portion 20 is constituted by a space surrounded by the front and rear horizontal portions 25, the horizontal guide plate 27, and the wide plate portion 25.

ほぞ部１５Ｂは側壁部１８を挟んで円壁部２１と対向する位置に配設されている。ほぞ部１５Ｂはパイプ材１２に嵌合されている。ほぞ部１５Ｂはパイプ材１２の内周のカーブに対応するカーブが外面に形成された一対の差し込み片２８と両差し込み片２８の間に配置された間隔保持片２９とから構成されている。差し込み片２８と側壁１８との接続部分はパイプ材１２の厚みに略一致する段差２８ａが形成されている。前記上方連通部１９は前後の側壁部１８と円壁部２１と間隔保持片２９とによって包囲された空間によって構成される。
このような構成のほぞ部１５Ｂに対してパイプ材１２はその端部側から嵌合させ、段差２８ａに突き合わせた状態で溶着されている。パイプ材１２の連結部１３への取着状態でパイプ材１２の外周面のカーブは側壁１８の外周面のカーブとほぼ連続的に接続されることとなる。 The tenon portion 15B is disposed at a position facing the circular wall portion 21 with the side wall portion 18 interposed therebetween. The tenon portion 15B is fitted to the pipe material 12. The tenon portion 15 </ b> B includes a pair of insertion pieces 28 in which a curve corresponding to the curve of the inner periphery of the pipe material 12 is formed on the outer surface, and a distance holding piece 29 disposed between the insertion pieces 28. A connecting portion between the insertion piece 28 and the side wall 18 is formed with a step 28 a that substantially matches the thickness of the pipe material 12. The upper communication portion 19 is constituted by a space surrounded by the front and rear side wall portions 18, the circular wall portion 21, and the interval holding piece 29.
The pipe member 12 is fitted to the tenon portion 15B having such a configuration from its end side and is welded in a state of being in contact with the step 28a. When the pipe member 12 is attached to the connecting portion 13, the curve of the outer peripheral surface of the pipe member 12 is connected almost continuously with the curve of the outer peripheral surface of the side wall 18.

第２の挿入部としての可動片１７は筐体部１５Ａ内に上下動可能に配設されている。可動片１７は等幅に形成された外側に凸である湾曲板部３０と、湾曲板部３０の内側の幅方向の端部に一体形成された一対の縁板部３１とから構成されている。湾曲板部３０の外面は滑らかな上下方向に渡って一定の曲率で構成された凸状の湾曲面３０ａとされており、湾曲面３０ａ側がパイプ材１２とは逆方向、つまり筐体部１５Ａ内において幅広板部２５を向くようにセットされている。
縁板部３１の端面に中央から若干上方に寄った位置には切り欠き部３２が形成されている。切り欠き部３２よりも上方側の縁板部３１の端面は一定の曲率で湾曲して構成された凹状の第１のスライド部３３とされている。一方、切り欠き部３２よりも下方側の縁板部３１の端面は第２のスライド部３４とされている。例えば図３（ａ）に示すように、第１のスライド部３３においては湾曲板部３０の外面（湾曲面）からの距離は一定であるが、第２のスライド部３４では上寄りほど距離が遠くなっている。図３（ａ）において第１のスライド部３３の湾曲板部３０の外面からの距離（つまり可動片１７の幅）をＬ１とすると、第２のスライド部３４側の対応する距離は下端側ではＬ１より短く上寄りでは長くなっている。最も長い位置をＬ２とすると、下方連通部２０の間隔Ｌ３よりもＬ２は若干長く構成されている。このような構成によって図３（ｂ）に示すように可動片１７が下動するとＬ２に近い位置で下方連通部２０内に嵌まり込みそれ以上の下動ができないようになっている。つまり、筐体部１５Ａから下方へ脱落することが防止されている。下方連通部２０と第２のスライド部３４側によって第１の保持手段が構成されている。
両縁板部３１の長手方向の中央位置には両縁板部３１の前後方向に突出するようにピン３５が固着されている。ピン３５の両端は側壁１８に形成された長孔２３内に進出させられている。このような構成によって可動片１７が筐体部１５Ａの上方連通部１９から上方へ抜けてしまうことが防止されている。 The movable piece 17 as the second insertion portion is disposed in the housing portion 15A so as to be movable up and down. The movable piece 17 includes an outwardly convex curved plate portion 30 that is formed to have an equal width, and a pair of edge plate portions 31 that are integrally formed at the end in the width direction inside the curved plate portion 30. . The outer surface of the curved plate portion 30 is a convex curved surface 30a configured with a constant curvature over a smooth vertical direction, and the curved surface 30a side is opposite to the pipe material 12, that is, inside the housing portion 15A. Is set so as to face the wide plate portion 25.
A notch 32 is formed in the end face of the edge plate 31 at a position slightly above the center. An end surface of the edge plate portion 31 above the notch portion 32 is a concave first slide portion 33 that is curved with a certain curvature. On the other hand, an end surface of the edge plate portion 31 below the notch portion 32 is a second slide portion 34. For example, as shown in FIG. 3A, the distance from the outer surface (curved surface) of the curved plate portion 30 is constant in the first slide portion 33, but the distance increases toward the upper side in the second slide portion 34. It ’s far away. 3A, when the distance from the outer surface of the curved plate portion 30 of the first slide portion 33 (that is, the width of the movable piece 17) is L1, the corresponding distance on the second slide portion 34 side is the lower end side. Shorter than L1 and longer on the upper side. If the longest position is L2, L2 is configured to be slightly longer than the interval L3 of the lower communication portion 20. With such a configuration, as shown in FIG. 3B, when the movable piece 17 moves downward, the movable piece 17 is fitted into the lower communication portion 20 at a position close to L2, and cannot be further moved downward. That is, it is prevented from dropping downward from the housing portion 15A. The lower communication part 20 and the second slide part 34 side constitute a first holding means.
A pin 35 is fixed to the center position in the longitudinal direction of both edge plate portions 31 so as to protrude in the front-rear direction of both edge plate portions 31. Both ends of the pin 35 are advanced into a long hole 23 formed in the side wall 18. With such a configuration, the movable piece 17 is prevented from coming out upward from the upper communication portion 19 of the housing portion 15A.

可動片１７は第１のスライド部３３がリベット２２に案内され、また、第２のスライド部３４が水平案内板２７に案内されてスムーズにかつ安定した湾曲面に沿った軌跡で上下動することとなる。また、水平案内板２７は可動片１７の先端が後述する係合部４４の干渉部４４ａから外方に逃げないようにする案内の役割もする。可動片１７の先端が干渉部４４ａの外側にあると透孔４５方向に導かれずに可動片１７を下降させても透孔４５内に挿入されなくなってしまうからである。可動片１７が下方に移動させられて図３（ｂ）のように下方連通部２０間に嵌まった状態（上記の脱落が防止された状態）が可動片１７の下端寄りが挿入片１６から最も離間した位置となる。
一方、図３（ａ）のように上方に移動させられて可動片１７が切り欠き部３２に筐体部１５Ａ側のリベット２２が係合された状態が最も上方に移動した状態である。この状態で可動片１７の下端寄りが最も挿入片１６に接近した位置となる。 The movable piece 17 moves up and down along a locus along a smooth and stable curved surface by the first slide portion 33 being guided by the rivet 22 and the second slide portion 34 being guided by the horizontal guide plate 27. It becomes. Further, the horizontal guide plate 27 also serves as a guide for preventing the tip of the movable piece 17 from escaping outward from an interference portion 44a of the engaging portion 44 described later. This is because if the tip of the movable piece 17 is outside the interference portion 44a, the movable piece 17 cannot be inserted into the through hole 45 even if the movable piece 17 is lowered without being guided toward the through hole 45. The state in which the movable piece 17 is moved downward and is fitted between the lower communication portions 20 as shown in FIG. 3B (the state in which the drop-off is prevented) is located closer to the lower end of the movable piece 17 from the insertion piece 16. It is the most distant position.
On the other hand, the state in which the movable piece 17 is moved upward as shown in FIG. 3A and the rivet 22 on the housing portion 15A side is engaged with the cutout portion 32 is the state in which the movable piece 17 is moved upward. In this state, the lower end of the movable piece 17 is closest to the insertion piece 16.

次に、このような構成の足場用布材１１の足場用支柱４１への架設作業について説明する。まず、足場用支柱４１について概略説明をする。
図４に示すように、足場用支柱４１の支柱本体４２には所定間隔で緊結ホルダー４３が形成されている。緊結ホルダー４３は４回対称となる回転対称形状の鍔状の金属板片である。緊結ホルダー４３には中央に足場用支柱４１を配置した状態で９０度ずつずれた４方向には独立した係合部４４が形成される。各係合部４４には６角形形状の透孔４５が形成され、支柱本体４２と対向する透孔４５を挟んだ位置に配置される辺は可動片１７が干渉する干渉部４４ａとされる。図５に示すように、透孔４５の径方向の幅をＬ４とする。 Next, the construction work of the scaffolding material 11 having such a structure on the scaffolding column 41 will be described. First, the scaffold post 41 will be outlined.
As shown in FIG. 4, tight holders 43 are formed at predetermined intervals on the column main body 42 of the scaffold column 41. The binding holder 43 is a rotationally symmetrical bowl-shaped metal plate piece that is four-fold symmetric. In the binding holder 43, independent engaging portions 44 are formed in four directions shifted by 90 degrees with the scaffolding column 41 disposed in the center. Each engagement portion 44 is formed with a hexagonal through hole 45, and the side disposed at a position sandwiching the through hole 45 facing the column main body 42 is an interference portion 44 a on which the movable piece 17 interferes. As shown in FIG. 5, the radial width of the through hole 45 is L4.

まず、図５に示すように足場用布材１１を緊結ホルダー４３の上方に配置する。この時可動片１７を筐体部１５Ａ内における最も下方側に移動させた位置とする（図３（ｂ）の状態）。これが連結部１３における可動片１７のデフォルト位置となる。この時、図３（ｂ）に示すように、挿入片１６と可動片１７とを併せた最大幅をＬ５とすると緊結ホルダー４３側の透孔４５の幅Ｌ４よりも幅Ｌ５は長く構成されていることとなる。
そして、この状態で、挿入片１６が緊結ホルダー４３の透孔４５内に収まるように足場用布材１１を下動させていく。すると、挿入片１６は透孔４５内に進出（下動）していくものの、可動片１７は緊結ホルダー４３の干渉部４４ａの上面に干渉してその場に留まることとなり、可動片１７は挿入片１６に対して相対的に上動することとなる。図６に示すように、挿入片１６の進出（下動）に伴って可動片１７は相対的な上動と同時に足場用支柱４１側に対しては矢印のように干渉部４４ａ上を徐徐に透孔４５方向に移動することとなる。そして、図７のように干渉部４４ａとの干渉関係がなくなった段階で一気に自重で透孔４５内に落下し、図８及び図９のように挿入片１６とともに透孔４５内に配置される。図９に示すように、挿入片１６はリベット２２と円壁部２１の内側面と干渉部４４ａの内側の下面角部の３カ所において接触して保持されることとなる。
連結部１３は水平板部２６の当接面２６ａが緊結ホルダー４３の上面に接地して位置決めされることとなる。この状態で、図９に示すように可動片１７は再びデフォルト位置に配置されることとなり、連結部１３を上方に移動させようとしても可動片１７の下端部分が干渉部４４ａの内側の下面角部に干渉してしまうため、連結部１３が緊結ホルダー４３から外れてしまうことはない。この状態で連結が完了する。よりしっかりと連結部１３を緊結ホルダー４３に固定するために必要な場合には可動片１７を軽く上方からハンマーのような工具で叩くようにしてもよい。尚、図６〜図８（図９）の動作は実際には足場用布材１１の下動動作に伴って瞬時に行われるものである。そのため、挿入片１６の方が若干早く下動するが、ほとんど時間差なく可動片１７も追随して下動することとなる。 First, as shown in FIG. 5, the scaffolding material 11 is disposed above the binding holder 43. At this time, the movable piece 17 is moved to the lowest position in the casing 15A (state shown in FIG. 3B). This is the default position of the movable piece 17 in the connecting portion 13. At this time, as shown in FIG. 3B, when the maximum width of the insertion piece 16 and the movable piece 17 is L5, the width L5 is configured to be longer than the width L4 of the through hole 45 on the binding holder 43 side. Will be.
Then, in this state, the scaffolding cloth material 11 is moved downward so that the insertion piece 16 fits in the through hole 45 of the binding holder 43. Then, although the insertion piece 16 advances (lowers) into the through hole 45, the movable piece 17 interferes with the upper surface of the interference portion 44a of the binding holder 43 and stays there, and the movable piece 17 is inserted. It moves up relative to the piece 16. As shown in FIG. 6, as the insertion piece 16 moves forward (downward movement), the movable piece 17 gradually moves on the interference portion 44a as shown by the arrow with respect to the scaffolding column 41 side at the same time as the relative upward movement. It moves in the direction of the through hole 45. Then, when the interference relationship with the interference portion 44a disappears as shown in FIG. 7, it falls into the through hole 45 by its own weight at a stroke, and is arranged in the through hole 45 together with the insertion piece 16 as shown in FIGS. . As shown in FIG. 9, the insertion piece 16 is held in contact with the rivet 22, the inner surface of the circular wall portion 21, and the lower corner portion on the inner side of the interference portion 44 a.
The connecting portion 13 is positioned with the contact surface 26 a of the horizontal plate portion 26 contacting the upper surface of the binding holder 43. In this state, as shown in FIG. 9, the movable piece 17 is again placed at the default position, and even if the connecting portion 13 is moved upward, the lower end portion of the movable piece 17 is the lower surface angle inside the interference portion 44a. Therefore, the connecting portion 13 is not detached from the binding holder 43. In this state, the connection is completed. If necessary to more firmly fix the connecting portion 13 to the binding holder 43, the movable piece 17 may be lightly hit from above with a tool such as a hammer. 6 to 8 (FIG. 9) is actually performed instantaneously with the downward movement of the scaffolding material 11. Therefore, the insertion piece 16 moves down slightly faster, but the movable piece 17 follows and moves down with little time difference.

一方、連結状態から連結部１３を緊結ホルダー４３から取り外す際には、可動片１７を下方から上方に押し上げるようにする。すると、可動片１７のみ上方へ移動し、その移動に伴って可動片１７の上端側がパイプ材１２方向に進出するため、連結状態でほぼ透孔４５内に存在していた重心もパイプ材１２方向に移動して可動片１７はパイプ材１２方向に倒れやすくなる。そのため、押し上げるだけで自然に可動片１７は筐体部１５Ａ側のリベット２２に第１のスライド部３３が案内され最終的に切り欠き部３２がリベット２２に係合されるようになる。図１０は可動片１７の切り欠き部３２がリベット２２に係合された状態である。この状態ですでに連結部１３の上方への移動が可能となっているため、足場用布材１１を持ち上げて取り外す。尚、長い間連結状態にあると可動片１７や挿入片１６を手では容易に押し上げられない場合がある。その場合には軽く下方からハンマーのような工具で叩くようにしてもよい。 On the other hand, when removing the connecting portion 13 from the binding holder 43 from the connected state, the movable piece 17 is pushed upward from below. Then, only the movable piece 17 moves upward, and the upper end side of the movable piece 17 advances in the direction of the pipe material 12 along with the movement. The movable piece 17 is likely to fall in the direction of the pipe material 12 by moving to. Therefore, the movable piece 17 is naturally guided by the rivet 22 on the housing portion 15 </ b> A side only by pushing up, and finally the notch 32 is engaged with the rivet 22. FIG. 10 shows a state in which the notch 32 of the movable piece 17 is engaged with the rivet 22. Since the upward movement of the connecting portion 13 is already possible in this state, the scaffolding material 11 is lifted and removed. In addition, when it is in a connected state for a long time, the movable piece 17 and the insertion piece 16 may not be easily pushed up by hand. In that case, it may be lightly struck with a tool such as a hammer from below.

上記のように構成することにより本実施の形態１の足場用布材１１は以下のような効果を奏する。
（１）足場用布材１１の連結部１３を緊結ホルダー４３上に載置するだけで、自動的に可動片１７が落下して緊結ホルダー４３と干渉する位置に配置されるため、従来のようにくさび片を打ち込まなくとも連結部１３を連結することができ、作業効率が向上する。
（２）可動片１７が最も下方向に移動した下方への抜け止め位置は同時に連結部１３を緊結ホルダー４３に連結した際に連結部１３を上方に移動させると緊結ホルダー４３に干渉する位置でもあるため両方の構造を別々に有する必要がなく、構造が簡単となる。
（３）連結状態から連結部１３を緊結ホルダー４３から取り外す際に可動片１７を上方に移動させると自動的に可動片１７を上方位置でリベット２２に支持させることができるため、取り外しの際の作業が効率化する。 By configuring as described above, the scaffolding fabric material 11 according to the first embodiment has the following effects.
(1) Since the movable piece 17 automatically falls and interferes with the binding holder 43 simply by placing the connecting portion 13 of the scaffolding cloth material 11 on the binding holder 43, it is as in the conventional case. Even if the wedge piece is not driven in, the connecting portion 13 can be connected, and the working efficiency is improved.
(2) The downward retaining position where the movable piece 17 has moved downward is the same as the position where it interferes with the fastening holder 43 when the connecting portion 13 is moved upward when the connecting portion 13 is connected to the fastening holder 43 at the same time. Therefore, it is not necessary to have both structures separately, and the structure becomes simple.
(3) Since the movable piece 17 can be automatically supported by the rivet 22 at the upper position when the movable piece 17 is moved upward when removing the connecting portion 13 from the binding holder 43 from the connected state, Work becomes more efficient.
