Description
本考案は、構造物の作業用ブラケット足場に関するものである。 The present invention relates to a work bracket scaffold for a structure.
従来から、擁壁などの傾斜面又は鉛直面を備える枠組み足場を設置できない条件下にある構造物を構築又は補修する際には、斜面の傾斜面又は鉛直面に沿った作業用ブラケット足場又は転落防止用作業床（以下、作業用ブラケット足場と称する）が使用されている。このような作業用足場は、鋼材からなる各部材を溶接によって連結することで構築されている。このため、設置の際には、斜面の勾配に合わせた作業用ブラケット足場を製作し、設置する高さに合わせてボルトなどで壁面に固定する必要があるなどの問題があった。 Conventionally, when constructing or repairing structures under conditions where it is not possible to install a framework scaffold with a sloped surface or vertical surface such as a retaining wall, a work bracket scaffold or fall along the sloped surface or vertical surface of the slope A work floor for prevention (hereinafter referred to as work bracket scaffold) is used. Such a working scaffold is constructed by connecting members made of steel by welding. For this reason, there has been a problem in that it is necessary to manufacture a work bracket scaffolding that matches the slope of the slope and to fix it to the wall surface with bolts or the like according to the installation height.
さらに、例えば、特許文献１では、ダムの越流部や擁壁等の簡易足場には、斜面足場用ブラケットが用いられ、この斜面足場用ブラケットは、水平材、取付材、斜材、手摺柱各々の連結に六角ボルトを使用している。このため、組み立て・解体の際には、各部材がバラバラになり乱雑となるうえ、ボルトを紛失する原因ともなっていた。また、水平材に軽量溝形鋼２本を使用しているために、一般に使用されている丸パイプ用クランプが使用できない。そのため、隣接するブラケット間が手摺の丸パイプだけで繋がった状態となり、手摺をセットするまでは動きやすく固定しにくかった。そこで、特許文献１には、水平材と取付材と斜材と手摺柱とからなる斜面足場用ブラケットが開示されている。これらの部材は、ピンによって一体化されているため、部品がばらばらになることはない。さらに、組み立て、及び解体が容易にできるようになる。また、水平材に丸パイプを使用したことで、布付き足場板を装着できるようになるため、足場板を装着した状態でも左右に振れずに安定し固定しやすくなる。 Further, for example, in Patent Document 1, a slope scaffolding bracket is used for a simple scaffold such as a dam overflow part or retaining wall, and the slope scaffolding bracket is composed of a horizontal member, a mounting member, a diagonal member, and a handrail column. Hexagon bolts are used for each connection. For this reason, when assembling and disassembling, each member becomes disjointed and messy, and the bolt is lost. Moreover, since two lightweight channel steels are used for the horizontal member, generally used round pipe clamps cannot be used. For this reason, the adjacent brackets are connected only by a round pipe of the handrail, and it is difficult to move and fix until the handrail is set. Therefore, Patent Document 1 discloses a bracket for slope scaffolding including a horizontal member, a mounting member, a diagonal member, and a handrail column. Since these members are integrated by pins, the parts do not fall apart. Further, assembly and disassembly can be easily performed. In addition, since a circular pipe is used as the horizontal member, a cloth-attached scaffolding plate can be attached, so that even when the scaffolding plate is attached, it can be stably fixed without shaking left and right.
しかしながら、特許文献１の斜面足場用ブラケットは、取付材に固定された取付フックを型枠の横端太に取り付け、浮き上がり防止具によって固定する構造になっている。そのため、横端太が存在する型枠の高さ位置のみに配置が限定される、という問題があった。 However, the bracket for slope scaffolding of Patent Document 1 has a structure in which an attachment hook fixed to an attachment member is attached to a thick lateral end of a formwork and is fixed by a lifting prevention tool. For this reason, there is a problem that the arrangement is limited only to the height position of the formwork where the thick side edges exist.
そこで、本考案は、型枠に加えて、構造物本体の任意の高さと任意の傾斜面又は鉛直面に配置することができる作業用ブラケット足場を提供することを目的としている。 Therefore, an object of the present invention is to provide a working bracket scaffold that can be disposed on an arbitrary height and an arbitrary inclined surface or vertical surface of a structure body in addition to a formwork.
前記目的を達成するために、本考案の作業用ブラケット足場は、傾斜面又は鉛直面を有する構造物の作業用ブラケット足場であって、前記構造物の基礎又はボルトなどに固定されて前記傾斜面又は鉛直面に沿って配置される縦支柱と、第１端部及び第２端部を有する水平材であり、前記第１端部が前記縦支柱の所定の箇所に回動可能に締結される、水平材と、前記水平材の前記第２端部に取り付けられる手摺柱と、前記水平材上に設置される足場板と、上端部及び下端部を有する斜材であり、前記上端部が前記水平材の前記第２端部に回動可能に連結されるとともに、前記下端部が、前記水平材が略水平になるように、前記縦支柱の所定の箇所に回動可能に締結される、斜材と、を備えることを特徴としている。 In order to achieve the above object, the work bracket scaffold of the present invention is a work bracket scaffold of a structure having an inclined surface or a vertical surface, and is fixed to the foundation or a bolt of the structure and the inclined surface. Or it is the horizontal material which has the vertical support | pillar arrange | positioned along a vertical surface, and a 1st end part and a 2nd end part, and the said 1st end part is fastened to the predetermined location of the said vertical support | pillar so that rotation is possible.

The diagonal member 6 is fastened to a predetermined portion of the vertical column 2 so as to be rotatable so as to be substantially horizontal.
縦支柱２は、図３に示すように、所定の長さの角形鋼管２０と、角形鋼管２０の一方の端部に溶接等によって固定された側板２１、２１と、を有している。なお、角形鋼管２０と側板２１の固定方法は、上述した方法に限定されるものではなく、強固に固定できれば、どのように固定してもよい。そして、各側板２１には取付孔２１ａが削孔されている。さらに、角形鋼管２０の側板２１、２１と反対側の他方の端部にも取付孔２０ａ、２０ａが削孔されている。そして、複数の縦支柱２、２を準備したうえで、一方の縦支柱２の側板２１、２１の取付孔２１ａ、２１ａと、他方の縦支柱２の取付孔２０ａ、２０ａの位置を合わせ、ボルト・ナットで連結することでヒンジ構造を構成できる。ヒンジ構造を介して、縦支柱２どうしが連結されることで、縦支柱２を相当の高さまで伸ばしていくことができる。なお、ヒンジ構造は、上述したボルト・ナットに限定されるものではなく、ヒンジ構造であれば、どのような構造であってもよい。 As shown in FIG. 3, the vertical column 2 includes a square steel pipe 20 having a predetermined length, and side plates 21 and 21 fixed to one end of the square steel pipe 20 by welding or the like. In addition, the fixing method of the square steel pipe 20 and the side plate 21 is not limited to the method described above, and may be fixed in any way as long as it can be firmly fixed. Each side plate 21 has a mounting hole 21a. Further, mounting holes 20a, 20a are also drilled in the other end of the rectangular steel pipe 20 opposite to the side plates 21, 21. Then, after preparing a plurality of vertical struts 2, 2, the mounting holes 21 a, 21 a of the side plates 21, 21 of one vertical strut 2 and the mounting holes 20 a, 20 a of the other vertical strut 2 are aligned, -A hinge structure can be configured by connecting with nuts. The vertical struts 2 can be extended to a considerable height by connecting the vertical struts 2 via the hinge structure. The hinge structure is not limited to the bolts and nuts described above, and may be any structure as long as it is a hinge structure.
また、縦支柱２のヒンジ構造の回動軸は、構造物の前面に配置された状態で、水平面内において傾斜面と平行になるように配置される。さらに、縦支柱２の取付孔２０ａ、２０ａと、側板２１の取付孔２１ａ、２１ａとは、同一方向に削孔されている。このような構成によって、縦支柱２は、傾斜面に沿って途中で傾斜を変更可能でありつつも、作業用ブラケット足場１の左右への転倒を防止できる。 Moreover, the rotation axis | shaft of the hinge structure of the vertical support | pillar 2 is arrange | positioned so that it may become in parallel with an inclined surface in the horizontal surface in the state arrange | positioned in the front surface of a structure. Furthermore, the mounting holes 20a, 20a of the vertical column 2 and the mounting holes 21a, 21a of the side plate 21 are drilled in the same direction. With such a configuration, the vertical support column 2 can prevent the work bracket scaffold 1 from falling to the left and right while being able to change the inclination along the inclined surface.

For this reason, it becomes the work bracket scaffold 1 which can be arrange | positioned in arbitrary heights.
すなわち、縦支柱２は、構造物側（基礎コンクリート９１）に固定されて、上下方向（縦方向）に伸びるように配置される。そして、この上下方向に伸びる縦支柱２の適切な位置を選択して３点ヒンジブラケット構造を設置できる。換言すると、型枠を押さえる端太の位置等に影響されることなく、足場を自由に配置できる。加えて、本実施例の構造であれば、構造物の傾斜に関係なく、足場を正確に水平に配置できるというメリットもある。さらに、軽量で運搬、組立・組外が容易な足場構造となる。また、３点ヒンジブラケットは、構造物の傾斜に合わせてその都度製作する必要がなく、別の構造物に転用することもできる。 That is, the vertical strut 2 is fixed to the structure side (foundation concrete 91) and arranged to extend in the vertical direction (vertical direction). And the three-point hinge bracket structure can be installed by selecting an appropriate position of the vertical column 2 extending in the vertical direction. In other words, the scaffold can be freely arranged without being affected by the position of the end thickness that holds the formwork. In addition, the structure of the present embodiment also has an advantage that the scaffold can be accurately placed horizontally regardless of the inclination of the structure. Furthermore, the scaffolding structure is lightweight and easy to transport, assemble and assemble. Further, the three-point hinge bracket does not need to be manufactured each time according to the inclination of the structure, and can be diverted to another structure.
（２）具体的な構造としては、水平材３の第１端部及び斜材６の０下端部には、それぞれヒンジとしてのヒンジ部材３２、６１を介してクランプ部材３３、６２が連結され、各クランプ部材３３、６２が縦支柱２を締め付けることによって、水平材３及び斜材６が縦支柱２に締結されることを特徴としている。このため、きわめて簡易な構造によって、任意の高さに水平に足場を設置できる。さらに、クランプ部材３３、６２を、ヒンジ部材３２、６１に対して、回転軸を介して連結することにより、横方向に足場を傾斜させて設置することもできる。 (2) As a specific structure, clamp members 33 and 62 are connected to the first end portion of the horizontal member 3 and the 0 lower end portion of the diagonal member 6 via hinge members 32 and 61 as hinges, respectively. The horizontal members 3 and the diagonal members 6 are fastened to the vertical columns 2 by the clamp members 33 and 62 tightening the vertical columns 2. For this reason, a scaffold can be installed horizontally at an arbitrary height with a very simple structure. Furthermore, by connecting the clamp members 33 and 62 to the hinge members 32 and 61 via a rotation shaft, it is possible to install the clamp members 33 and 62 with the scaffold inclined in the lateral direction.
（３）さらに、縦支柱２は、ヒンジを介して継足すことができるように形成され、ヒンジの回動軸は、水平面内において傾斜面と平行になるように配置される。すなわち、縦支柱２が一方の端部の側板２１に設けた取付孔２１ａと他方の端部に設けた取付孔２０ａとを有することで、複数の縦支柱２、・・・を継ぎ足しながら伸ばしていくことができる。さらに、回動軸を傾斜面と平行になるように配向して設置することで、足場の左右への転倒を防止できる。 (3) Further, the vertical column 2 is formed so as to be able to be connected via a hinge, and the rotation axis of the hinge is arranged to be parallel to the inclined surface in the horizontal plane. That is, the vertical column 2 has the mounting hole 21a provided in the side plate 21 at one end and the mounting hole 20a provided in the other end, so that the plurality of vertical columns 2,. I can go. Furthermore, the scaffold can be prevented from falling to the left and right by installing the rotating shaft so as to be parallel to the inclined surface.
（４）また、縦支柱２の最下部は、構造物の基礎に固定されたヒンジを介して、構造物の基礎に回動可能に連結されることで、構造物の傾斜に合わせて作業用ブラケット足場１を設置できる。 (4) Further, the lowermost part of the vertical support column 2 is connected to the foundation of the structure via a hinge fixed to the foundation of the structure so that it can be rotated according to the inclination of the structure. The bracket scaffold 1 can be installed.
（５）そして、縦支柱２と傾斜面との間隔を保持する間隔保持部材７をさらに備えることで、足場と傾斜面との距離を一定に保持できるため、足場上で作業しやすくなる。間隔保持部材７は、構造物躯体に固定することもできる。なお、間隔保持部材７を構造物側に固定しない場合には、全体の重心を足場が転倒しないように配分する必要がある。すなわち、図１の一点鎖線に示すように、最下段の３点ヒンジブラケット構造が基礎部８の回動軸よりも構造物側に位置していることが必要である。 (5) Since the distance holding member 7 that holds the distance between the vertical column 2 and the inclined surface is further provided, the distance between the scaffold and the inclined surface can be kept constant, so that it becomes easy to work on the scaffold. The spacing member 7 can also be fixed to the structure housing. In addition, when the space | interval holding member 7 is not fixed to the structure side, it is necessary to distribute the whole gravity center so that a scaffold may not fall down. That is, as shown by the one-dot chain line in FIG. 1, the lowermost three-point hinge bracket structure needs to be positioned on the structure side with respect to the rotation shaft of the base portion 8.
以上、図面を参照して、本考案の実施例を詳述してきたが、具体的な構成は、この実施例に限らず、本考案の要旨を逸脱しない程度の設計的変更は、本考案に含まれる。 The embodiment of the present invention has been described in detail with reference to the drawings, but the specific configuration is not limited to this embodiment, and design changes that do not depart from the gist of the present invention can be made in the present invention. included.
例えば、実施例では、縦支柱２、水平材３、斜材６として角形鋼管を用いる場合について説明したが、これに限定されるものではなく、いわゆる単管パイプを用いることもできるし、溝形鋼など他の部材を用いることもできる。さらに、水平材３の内空に水平材３の内径より小さい径の鋼管を摺動自在に挿入し、必要に応じて伸長させることで足場幅を拡幅することもできる。 For example, in the embodiment, the case where a square steel pipe is used as the vertical column 2, the horizontal member 3, and the diagonal member 6 has been described. Other members such as steel can also be used. Furthermore, the scaffold width can be widened by inserting a steel pipe having a diameter smaller than the inner diameter of the horizontal member 3 into the inner space of the horizontal member 3 so as to be slidable and extending as necessary.
また、実施例では、傾斜面を有する構造物に本考案の作業用ブラケット足場１を適用する場合について説明したが、これに限定されるものではない。鉛直面を有する構造物に本考案を適用することもできるし、傾斜面と鉛直面の両方を有する構造物に本考案を適用することもできる。 Moreover, although the Example demonstrated the case where the work bracket scaffold 1 of this invention was applied to the structure which has an inclined surface, it is not limited to this. The present invention can be applied to a structure having a vertical surface, and the present invention can also be applied to a structure having both an inclined surface and a vertical surface.
