Description

この発明は、各種作業用の足場や支保工を組み立てる仮設構造物において、特に足場板の長手方向に取付けられる巾木の取付構造に関するものである。 The present invention relates to a baseboard attachment structure that is attached in the longitudinal direction of a scaffold plate, particularly in a temporary structure for assembling scaffolds and supporting works for various operations.

本出願人は仮設構造物について、作業員や資材の落下を防止するための手摺り枠に関する技術を既に開示している（例えば、特許文献１、２）。 The present applicant has already disclosed a technique related to a handrail frame for preventing a worker or material from falling about a temporary structure (for example, Patent Documents 1 and 2).

上記手摺り枠は、主として作業員の落下防止を目的としており、これより小さい工具や資材については落下防止は期しがたい。また、単なる平板状の足場板だけでは、作業員が足を踏み外すことも考えられる。 The handrail frame is mainly intended to prevent the worker from falling, and it is difficult to prevent the tool and material smaller than this from falling. In addition, it is conceivable that an operator steps off his / her foot with a simple flat plate.

そこで、従来から足場板の左右縁には作業員の膝下程度の高さの巾木を取付けて、工具や資材の落下を防止し、作業員が誤って足を踏み外さないような構造を採用することがある。 Therefore, traditionally, a baseboard that is about the height of the worker's knees is attached to the left and right edges of the scaffolding plate to prevent tools and materials from falling and prevent the worker from accidentally stepping off the foot. There are things to do.

こうした背景に鑑み、本発明の目的とするところは、簡易に取付けられ、しかも取り付け後、ぐらつきや不用意な脱落もなく、また小物も確実に落下防止を図ることができる巾木の取付構造を開示することである。 In view of such a background, the object of the present invention is to provide a baseboard mounting structure that can be easily attached, and does not wobble or inadvertently fall off after attachment, and can reliably prevent small items from falling. It is to disclose.

上述した目的を達成するために本発明では、足場板の長手方向に沿って巾木を取付ける構造であって、足場板は隅角部付近の上面および側面に係合孔を設けてなる一方、巾木は立ち上がり板と、該立ち上がり板の下方に位置して設けられ、足場板の前記隅角部と合致するように水平部と垂直部からなる屈曲部材の前記水平部および垂直部それぞれに前記係合孔と嵌合可能な係合片を設けてなる取付金具とから巾木の取付構造を構成した。本発明によれば、９０度の関係にある係合片によって巾木を取付けるものであるから、両者が共働で双方の抜け止め機能を発揮する。 In order to achieve the above-described object, the present invention has a structure in which the baseboard is attached along the longitudinal direction of the scaffold plate, and the scaffold plate is provided with engagement holes on the upper surface and the side surface near the corner, The baseboard is provided on the rising plate and the lower portion of the rising plate, and each of the horizontal portion and the vertical portion of the bending member including the horizontal portion and the vertical portion so as to coincide with the corner portion of the scaffold plate. A baseboard attachment structure was configured from an attachment fitting provided with an engagement piece that can be engaged with the engagement hole. According to the present invention, since the baseboard is attached by the engagement pieces having a 90-degree relationship, the both work together to exert both retaining functions.

係合孔は足場板の長手方向に向かって長孔に形成されると共に、巾木の少なくとも一方の係合片はその下端を長手方向に９０度屈曲してなる抜け止め爪を具備し、当該係合片を前記係合孔に差し込み後、スライドさせることにより係合孔から抜脱不能とすることによって、抜け止め爪がより確実な抜け止め機能を発揮する。 The engagement hole is formed as a long hole in the longitudinal direction of the scaffolding plate, and at least one engagement piece of the baseboard is provided with a retaining claw having its lower end bent 90 degrees in the longitudinal direction. By making the engagement piece inserted into the engagement hole and then sliding it, it is impossible to remove the engagement piece from the engagement hole, so that the retaining claw exhibits a more reliable retaining function.

巾木の取付金具は、その屈曲部材の垂直部に足場板の側面に向かって弾発的に付勢されたピン部材を有すると共に、足場板の側面には前記スライドした状態で、ピン部材が嵌合する丸孔を設けることによって、ピン部材が丸孔に嵌合したとき、そのクリック音によってスライドにより抜け止め爪が係合孔に係合したことを知ることができる。 The base metal mounting bracket has a pin member that is elastically biased toward the side surface of the scaffolding plate at a vertical portion of the bending member, and the pin member is in a sliding state on the side surface of the scaffolding plate. By providing the round hole to be fitted, when the pin member is fitted into the round hole, it is possible to know that the retaining claw has been engaged with the engagement hole by sliding due to the click sound.

巾木の立ち上がり板は、屈曲部材の垂直部から水平部に向かって内側に折曲されたチャンネル部を介して、取付金具から上方部分が足場板の側面と同一線上若しくはこれよりも内側より立ち上がるように構成することによって、立ち上がり板は足場板の側面よりも内寄りに位置することになる。 The rising board of the baseboard rises from the vertical part of the bending member to the horizontal part toward the horizontal part, the upper part from the mounting bracket rises on the same line as the side face of the scaffolding board or from the inside. With such a configuration, the rising plate is positioned more inward than the side surface of the scaffold plate.

上述したように本発明によれば、巾木を足場板の上面および側面に同時に係合させ得る取付金具を採用したので、簡易に取付けが可能でありながら、ぐらつきや不用意な脱落がなく、巾木を足場板に取付けることができる。このとき、本発明の巾木は、下段の足場板から一つ上の足場板に先行して取付けることができるため、安全に巾木の取付作業を行うことができる。また、係合片を係合孔に嵌合した後、スライドさせて抜け止め爪を係合孔に係合する構造を採用したので、係合片の係合孔からの抜脱機能が高まり、より強固に巾木を取付けることができる。また、弾発的に丸孔に嵌合するピン部材のクリック音により、上記スライドによる抜け止め爪の係合を知ることができるので、作業性を向上させることができる。 As described above, according to the present invention, since the mounting bracket capable of simultaneously engaging the baseboard with the upper surface and the side surface of the scaffolding plate is adopted, it can be easily mounted without wobbling or inadvertent dropping. A baseboard can be attached to the scaffolding board. At this time, since the baseboard of the present invention can be attached in advance to the scaffold board one level higher than the lower stage scaffold board, the baseboard can be safely attached. In addition, since the engagement piece is fitted into the engagement hole and then slid to engage the retaining claw with the engagement hole, the function of removing the engagement piece from the engagement hole is enhanced. A baseboard can be attached more firmly. Further, since the engagement of the retaining pawl due to the slide can be known from the click sound of the pin member that is elastically fitted into the round hole, workability can be improved.

さらに、巾木の立ち上がり板の取付金具から上方部分を足場板の側面と同一線上若しくはこれよりも内側より立ち上がるように構成したので、足場板の側面と立ち上がり板の間に隙間が生ぜず、小物の落下をより確実に防止することができる。 In addition, since the upper part of the base plate from the mounting plate of the baseboard rises from the same line as the side of the scaffolding board or from the inside, there is no gap between the side of the scaffolding board and the rising board, and small items fall. Can be prevented more reliably.

以下、本発明の好ましい実施の形態を添付した図面に従って説明する。図１、２は、本発明の一実施形態に係る巾木を示したものであり、図中、１は横長の立ち上がり板、２はその下方数カ所（本実施形態では３箇所）に設けられた取付金具である。取付金具２は９０度に折曲してなる略逆Ｌ字状の屈曲部材３の水平部４先端および垂直部５下端をさらに９０度折曲して、係合片６・７を形成している。この取付金具２は、屈曲部３の垂直部５背面を溶接等により立ち上がり板１の下方に固定しているのであるが、ここで立ち上がり板１は取付金具２の固定箇所から屈曲部材３の水平部４に沿って内側に折曲してチャンネル部１ａを形成し、立ち上がり板１の取付金具２よりも上方部分が屈曲部材３の垂直部５よりも内側に位置するように構成されている。また、立ち上がり板１の下方部分はコ字状に折曲され受け部１ｂを形成し、該受け部１ｂにはＪ字状（受け部の深さによってはＵ字状でも可）の板バネ８が収容され、該板バネ８によりピン部材９を弾発的に突出するように付勢している。さらに、取付金具２の係合片６・７は、図２において円で囲った拡大図に示すように、その先端を巾木の長手方向に向かって９０度に折曲して抜け止め爪１０ａ・１０ｂを形成している。この実施形態では双方の係合片６・７に抜け止め爪１０ａ・１０ｂを形成することとしたが、何れか一方の係合片６・７のみに形成することも可能である。 Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. 1 and 2 show a baseboard according to an embodiment of the present invention. In the figure, 1 is a horizontally long rising plate, and 2 is provided at several locations below (three in this embodiment). It is a mounting bracket. The mounting bracket 2 is further bent 90 degrees at the distal end of the horizontal portion 4 and the lower end of the vertical portion 5 of the substantially inverted L-shaped bending member 3 bent at 90 degrees to form engagement pieces 6 and 7. Yes. In this mounting bracket 2, the back surface of the vertical portion 5 of the bent portion 3 is fixed to the lower portion of the rising plate 1 by welding or the like. The channel portion 1 a is formed by bending inward along the portion 4, and the upper portion of the rising plate 1 is positioned inward of the vertical portion 5 of the bending member 3. Further, the lower portion of the rising plate 1 is bent in a U shape to form a receiving portion 1b. The receiving portion 1b has a J-shaped plate spring 8 (may be U-shaped depending on the depth of the receiving portion). And the pin spring 9 is urged by the leaf spring 8 so as to project elastically. Further, as shown in the enlarged view surrounded by a circle in FIG. 2, the engagement pieces 6 and 7 of the mounting bracket 2 are bent at 90 degrees in the longitudinal direction of the baseboard to prevent the retaining claws 10a. -10b is formed. In this embodiment, the retaining claws 10a and 10b are formed on both the engaging pieces 6 and 7. However, it is also possible to form the retaining claws 10a and 10b only on one of the engaging pieces 6 and 7.

これに対して足場板は、図３に示すように、隅角部１１に近傍する上面１２および側面１３の３箇所に、取付金具２に対応した間隔で、前記係合片６・７が嵌合可能な係合孔１４・１５が形成されている。該係合孔１４・１５は抜け止め爪１０ａ・１０ｂをも差し込むことができるように、長手方向に向かって長孔に形成されている。即ち、当該構成により、係合片６・７を係合孔１４・１５に差し込んだ後、巾木をスライドさせることによって、抜け止め爪１０ａ・１０ｂが足場板の内部において係合孔１４・１５に係合して、取付金具２がロックされることとなる。さらに、足場板の側面１３には、前記スライド後に、ピン部材９が嵌合する丸孔１６が形成されており、ピン部材９が該丸孔１６に嵌合したときに発生するクリック音によって取付金具２がロックされたことを知ることができる。 On the other hand, as shown in FIG. 3, in the scaffold plate, the engagement pieces 6 and 7 are fitted at three positions on the upper surface 12 and the side surface 13 near the corner portion 11 at intervals corresponding to the mounting bracket 2. Engaging engagement holes 14 and 15 are formed. The engagement holes 14 and 15 are formed as long holes in the longitudinal direction so that the retaining claws 10a and 10b can be inserted. That is, according to this configuration, after the engagement pieces 6 and 7 are inserted into the engagement holes 14 and 15, the baseboards are slid so that the retaining claws 10a and 10b are engaged with the engagement holes 14 and 15 inside the scaffold plate. And the mounting bracket 2 is locked. Further, a round hole 16 into which the pin member 9 is fitted after the sliding is formed on the side surface 13 of the scaffold plate, and the side plate 13 is attached by a click sound generated when the pin member 9 is fitted into the round hole 16. It can be known that the metal fitting 2 is locked.

上記構成の巾木を足場板に取付けるには、図４〜６に示したように、先ず巾木を斜めに倒した状態として、足場板の上面１２側係合孔１４に取付金具２の水平部４側係合片６を差し込む（図４）。なお、足場板はもちろん、本発明の巾木も、下階からの作業により上階に先行取り付けすることができるから、作業性の安全が確保される。そして、立ち上がり板１が起立するように、巾木全体を回転させ（図５）、取付金具２の垂直部５側係合片７を足場板の側面１３側係合孔１５に差し込む（図６）。ここで、各係合片６・７に抜け止め爪１０ａ・１０ｂを形成していなかったとしても、水平部４側係合片６の抜けは垂直部５側係合片７によって、垂直部５側係合片７の抜けは水平部４側係合片６によって、それぞれ規制されるから、巾木の不用意な脱落はある程度防止することができる。 In order to attach the baseboard having the above-described structure to the scaffolding plate, as shown in FIGS. 4 to 6, first, the baseboard is tilted obliquely, and the mounting bracket 2 is horizontally inserted into the upper surface 12 side engagement hole 14 of the scaffolding plate. The part 4 side engagement piece 6 is inserted (FIG. 4). In addition to the scaffolding board, the baseboard of the present invention can be attached in advance to the upper floor by work from the lower floor, so that the safety of workability is ensured. Then, the entire baseboard is rotated so that the rising plate 1 rises (FIG. 5), and the vertical portion 5 side engagement piece 7 of the mounting bracket 2 is inserted into the side surface 13 side engagement hole 15 of the scaffold plate (FIG. 6). ). Here, even if the retaining claws 10a and 10b are not formed on the engaging pieces 6 and 7, the horizontal part 4 side engaging piece 6 is removed by the vertical part 5 side engaging piece 7 and the vertical part 5 Since the disconnection of the side engaging pieces 7 is regulated by the horizontal portion 4 side engaging pieces 6, inadvertent dropping of the baseboard can be prevented to some extent.

しかし、本実施形態では各係合片６・７の先端に抜け止め爪１０ａ・１０ｂを形成し、上記差し込み後に巾木をスライドさせることによって、足場板の裏側において抜け止め爪１０ａ・１０ｂを係合孔１４・１５に係合するようにしているため、より確実に巾木のぐらつきや不用意な脱落を防止することができる。図６においては、当該スライド前の状態を示しているから、ピン部材９は足場板側面１３の丸孔１６と合致せず、足場板の側面１３と当接して、板バネ８の付勢力に抗し後退した状態にあるが、この状態から巾木を図面の紙面奥に向かってスライドさせることによりピン部材９が丸孔１６に弾発的に嵌合することはもちろんである。 However, in the present embodiment, the retaining claws 10a and 10b are formed at the tips of the engagement pieces 6 and 7, and the baseboard is slid after the insertion, thereby engaging the retaining claws 10a and 10b on the back side of the scaffolding plate. Since the joint holes 14 and 15 are engaged with each other, it is possible to more reliably prevent the baseboard from wobbling or inadvertently falling off. In FIG. 6, since the state before the slide is shown, the pin member 9 does not coincide with the round hole 16 on the side surface 13 of the scaffold plate, but abuts on the side surface 13 of the scaffold plate, so Of course, the pin member 9 is elastically fitted into the round hole 16 by sliding the baseboard from this state toward the back of the drawing sheet.

さらに、図６から明らかなように、本実施形態では、巾木の取り付け後、立ち上がり板１のチャンネル部１ａが取付金具２の垂直部５の厚みを吸収して、立ち上がり板１の取付金具２よりも上方部分は足場板の側面１３よりも内側から立ち上がることになるため、足場板の側面１３と立ち上がり板１の間に隙間が生ぜず、小物の落下も確実に防止することができる。ここで、チャンネル部１ａの幅を大きく確保すると、足場板の上面の有効面積が減少するため、その幅は巾木を取付けた後に足場板の側面１３と隙間ができない最小限の幅に設定することが好ましい。 Further, as is apparent from FIG. 6, in this embodiment, after attaching the baseboard, the channel portion 1 a of the rising plate 1 absorbs the thickness of the vertical portion 5 of the mounting bracket 2, and the mounting bracket 2 of the rising plate 1. Since the upper part rises from the inner side than the side surface 13 of the scaffolding plate, no gap is formed between the side surface 13 of the scaffolding plate and the rising plate 1, and the fall of small items can be reliably prevented. Here, if the width of the channel portion 1a is ensured to be large, the effective area of the upper surface of the scaffold plate is reduced. Therefore, the width is set to a minimum width that does not allow a gap with the side surface 13 of the scaffold plate after the baseboard is attached. It is preferable.

なお、この実施形態では、巾木と足場板を３箇所において取付けるようにしたが、取付金具２や係合孔１４・１５の数はこれに限らず、例えば、それぞれ巾木および足場板の中央１箇所または前後２箇所に設けることであってもよいし、４箇所以上に設けることであってもよい。また、取付金具２と係合孔１４・１５の数も必ずしも同数とすることはなく、取付金具２の数を係合孔１４・１５よりも少なくすることも可能である。 In this embodiment, the baseboard and the scaffold board are attached at three locations. However, the number of the mounting bracket 2 and the engagement holes 14 and 15 is not limited to this, and for example, the center of the baseboard and the scaffold board, respectively. It may be provided at one place or at two places before and after, or may be provided at four or more places. Further, the number of mounting brackets 2 and the engagement holes 14 and 15 are not necessarily the same, and the number of mounting brackets 2 can be smaller than that of the engagement holes 14 and 15.

さらに、一枚の足場板により足場を構築する場合は、その左右側面および両隅角部の上面に係合孔１４・１５を形成する必要があるが、図７に示したように、足場板を複数並設する場合（図７は２枚の足場板を並設）は、最も外側に位置する足場板の一方側面および片側の隅角部上面に係合孔１４・１５を形成することで足りる。 Furthermore, when constructing a scaffold with a single scaffold plate, it is necessary to form engagement holes 14 and 15 on the left and right side surfaces and the upper surfaces of both corners, but as shown in FIG. When two or more scaffolds are arranged side by side (FIG. 7 shows two scaffold plates arranged side by side), the engagement holes 14 and 15 are formed on one side surface of the outermost scaffold plate and the upper surface of one corner. It ’s enough.
