Description

本発明は建築用足場を構築するに際し、所定間隔を保って立設する建枠の間に架設するための足場用踏板に関する。   The present invention relates to a scaffolding tread for erection between building frames that are erected at a predetermined interval in constructing a building scaffold.

従来、建造物等の建築のために足場を形成するに際しては、所要数所定間隔を保って対向させた建枠の夫々の間に、足場用踏板を水平状態で架設すること通例とする。 そして、当該足場用踏板の架設は、その両端に突設するつかみ金具を、建枠の水平杆部分に引っ掛けてその固定化を図るものである。   Conventionally, when forming a scaffold for building such as a building, it is customary to install a scaffolding tread in a horizontal state between each of the building frames facing each other with a predetermined number of intervals. And the construction of the footboard for scaffolding is intended to fix the holding metal fittings protruding at both ends thereof by hooking them on the horizontal ridge portion of the building frame.

ところで、上述したような形態で、各建枠間に足場用踏板を水平にかつ一列状に架設した場合、当該踏板の夫々の端部の対向部分には、必然的に隙間が生じてしまうこととなる。 すなわち、足場用の踏板の両端部の両側につかみ金具を突出させて形成してあるため、当該突出状態のつかみ金具を、建枠の水平杆部分に引っ掛けた場合、各足場用踏板の端縁間には、当該つかみ金具の突出長さ分の空間的隙間が生じてしまうこととなる。 そして、このような空間的隙間の存在は、作業員が足を引っ掛けて重大事故を招いてしまったり、作業用の部品を落下させてしまったりするような問題が生じることを余儀なくされた。   By the way, when the scaffolding treads are laid horizontally and in a row between the building frames in the form as described above, gaps are inevitably generated in the opposing portions of the respective end portions of the treads. It becomes. In other words, since the grip brackets are formed on both sides of the both ends of the scaffolding tread, when the projecting grip bracket is hooked on the horizontal heel part of the building frame, the edge of each scaffold tread In the meantime, a spatial gap corresponding to the protruding length of the gripping metal is generated. The existence of such a spatial gap has inevitably caused problems such as a worker getting caught in a foot and causing a serious accident or dropping work parts.

従来、このような問題を解決するための手段としては、当該空間的隙間を埋めるために、足場用踏板の端縁長さとほぼ等しい長さを具えた巾木状の板材を用い、当該巾木状の板材の嵌め込むように構成したものがある（例えば、特許文献１参照。）   Conventionally, as a means for solving such a problem, in order to fill the spatial gap, a baseboard-like board material having a length substantially equal to the edge length of the scaffolding tread is used. There is a configuration in which a plate-like plate material is fitted (for example, see Patent Document 1).

特開２００８−５０９３９号公報JP 2008-50939 A

上述したような巾木状の板材で、各足場用踏板の端部空間を埋めるように構成したものであると、当該巾木状板材が別体部材であるため、各足場用踏板を架設した後に、これを嵌め込まなければならないため、足場構築用作業の煩雑性が伴うばかりでなく、そのための作業時間も掛かってしまうこととなった。 更に、当該巾木状の板材を、足場用踏板とは別個に保管し、使用する足場用踏板に合せてその数量を用意しなければならないというような保管上の煩雑性が伴うことを余儀なくされた。   When the baseboard-like board material as described above is configured to fill the end space of each scaffolding tread, the scaffolding board is constructed because the baseboard board is a separate member. Since this has to be inserted later, not only is the work for constructing the scaffold complicated, but it also takes time for the work. Furthermore, the baseboard-like plate material must be stored separately from the scaffolding tread, and the storage complexity of having to prepare the quantity according to the scaffolding tread to be used is inevitably involved. It was.

本発明はこのような従来の問題の解消化を図った新規の足場用踏板の提供を図ったものである。   The present invention is intended to provide a novel scaffold tread that solves such conventional problems.

The present invention relates to a scaffold tread that is configured to additionally fix a gap filling material 3 having a side-right triangular shape that is a horizontal plane to be the same horizontal plane as the scaffold tread main body 1.

本発明は請求項２に記載したように、両端面の両側部に架設用つかみ金具２を突設して成る公知の足場用踏板主体１に於いて、当該両端面の中央に、上面3ａを当該足場用踏板主体１と同一水平面とするための水平面とした側面直角三角形状を呈する隙間埋め材３を、付加的に固設すると共に、当該隙間埋め材３は、その長さ方向の幅寸法Ｍが、架設用つかみ金具２を掛け止めるための足場構築用建枠Ａにおける管状横架材ａに対して、その中心軸線を越えない位置にしてかつその上方位置に先端が臨まされる程度の寸法とするように構成した足場用踏板を実施の態様とする。 According to the present invention, as described in claim 2, in a well-known scaffold tread main body 1 formed by protruding gripping metal fittings 2 on both sides of both end surfaces, an upper surface 3a is formed at the center of the both end surfaces. A gap filling material 3 having a right side triangular shape that is a horizontal plane to be the same horizontal plane as the scaffolding tread main body 1 is additionally fixed, and the gap filling material 3 has a width dimension in its length direction. M is such that the front end of the tubular horizontal member a in the scaffold construction building frame A for holding the erection clasp 2 is positioned so as not to exceed the center axis and to be positioned above the center axis. A footboard for scaffolding configured to have dimensions is used as an embodiment.

本発明は請求項３に記載したように、両端面の両側部に架設用つかみ金具２を突設して成る公知の足場用踏板主体１に於いて、当該両端面の中央に、上面3ａを当該足場用踏板主体１と同一水平面とするための水平面とした側面直角三角形状を呈する隙間埋め材３を、付加的に固設すると共に、当該隙間埋め材３は、その長さ方向の幅寸法Ｍが、架設用つかみ金具２を掛け止めるための足場構築用建枠Ａにおける管状横架材ａに対して、その中心軸線を越えない位置にしてかつその上方位置に先端が臨まされる程度の寸法とし、更に、その横幅寸法Ｌを足場用階段Ｂのつかみ金具ｂの間隔より内輪とする寸法に設定するように構成した足場用踏板を実施の態様とする。   According to the present invention, as described in claim 3, in a well-known scaffold tread plate main body 1 in which the gripping metal fittings 2 are provided on both sides of both end surfaces, an upper surface 3a is formed at the center of the both end surfaces. A gap filling material 3 having a right side triangular shape that is a horizontal plane to be the same horizontal plane as the scaffolding tread main body 1 is additionally fixed, and the gap filling material 3 has a width dimension in its length direction. M is such that the front end of the tubular horizontal member a in the scaffold construction building frame A for holding the erection clasp 2 is positioned so as not to exceed the center axis and to be positioned above the center axis. Further, a scaffolding tread that is configured to have a size and a width L that is set to be an inner ring based on the interval between the grips b of the staircase B for scaffolding is an embodiment.

本発明は請求項４に記載したように、隙間埋め材３として、一枚の板材を折曲げて成形したものを用いるように構成した請求項１乃至請求項3の何れかに記載の足場用踏板を実施の態様とする。 As described in claim 4, the present invention is the scaffold according to any one of claims 1 to 3, wherein the gap filling material 3 is formed by bending a single plate material. A tread is an embodiment.

本発明は請求項５に記載したように、隙間埋め材３として、引き抜き加工に基づき三角形のパイプ状に成形したものを用いるように構成した請求項１乃至請求項3の何れかに記載の足場用踏板を実施の態様とする。   As described in claim 5, the present invention provides a scaffold according to any one of claims 1 to 3, wherein the gap filling material 3 is formed into a triangular pipe shape based on a drawing process. A tread board is an embodiment.

本発明は請求項１に記載したような構成、すなわち、両端面の両側部に架設用つかみ金具２を突設して成る公知の足場用踏板主体１に於いて、当該両端面の中央に、上面3ａを当該足場用踏板主体１と同一水平面とするための水平面とした側面直角三角形状を呈する隙間埋め材３を、付加的に固設するように構成したから、複数の建枠Ａを介して一直線状に並べられた各足場用踏板主体１の突合せ間隙部（建枠Ａの管状横架材ａに架設した部分の間隙）は、夫々の足場用踏板主体１に固設されている隙間埋め材３によって、当該間隙部分を覆うが如きカバー状態に保たれることとなり、従って、当該間隙部の存在に基づく部品の不測の落下事故、或いは、作業員が足を引っ掛けての落下事故というような事態発生を未然に防ぐこととなる。 そして、本発明はこのような作用を奏させるための隙間埋め材３を足場用踏板主体１に固設するように構成したから、これを別部品化したような従来品（例えば特許文献１に記載されたもの）において生じた、組立て作業の煩雑性と部品管理の煩雑性というような問題が全く解消されることとなる。   The present invention has a structure as described in claim 1, that is, in a well-known scaffold tread main body 1 formed by projecting gripping metal fittings 2 on both sides of both end faces, Since the gap filling material 3 having a side-right triangular shape in which the upper surface 3a is the same horizontal plane as the scaffolding tread main body 1 is configured to be additionally fixed, the plurality of building frames A are interposed. The butt gaps (the gaps between the portions of the building frame A laid on the tubular horizontal member a) of the scaffold treads 1 arranged in a straight line are the gaps fixed to the respective scaffolds treads 1. The filling material 3 covers the gap portion, and the cover state is maintained. Therefore, an accidental drop accident of a part based on the existence of the gap portion, or a fall accident in which an operator catches the foot. Such a situation will be prevented in advance. And since this invention comprised so that the gap filling material 3 for having such an effect | action might be fixedly provided to the footboard main body 1 for scaffolding, it is a conventional product which made this another part (for example, patent document 1) The problems such as the complexity of assembling work and the complexity of parts management, which occur in the above-described (1) described, are completely solved.

更に、本発明は公知の足場用踏板主体１に対する実施、すなわち、既に使用されている足場用踏板主体１であっても、これに隙間埋め材３を付加的に固設するだけで、上記のような作用効果を奏する本発明の実施が可能とされるものであるから、その実施は低コストで達成される。   Furthermore, the present invention can be applied to a well-known scaffold tread main body 1, that is, even if the scaffold tread main body 1 is already used, only the gap filling material 3 is additionally fixed to the above. Since it is possible to implement the present invention with such operational effects, the implementation is achieved at low cost.

本発明は請求項２に記載のような構成、すなわち、両端面の両側部に架設用つかみ金具２を突設して成る公知の足場用踏板主体１に於いて、当該両端面の中央に、上面3ａを当該足場用踏板主体１と同一水平面とするための水平面とした側面直角三角形状を呈する隙間埋め材３を、付加的に固設すると共に、当該隙間埋め材３は、その長さ方向の幅寸法Ｍが、架設用つかみ金具２を掛け止めるための足場構築用建枠Ａにおける管状横架材ａに対して、その中心軸線を越えない位置にしてかつその上方位置に先端が臨まされる程度の寸法とするように構成したから、請求項１の場合と同様な作用効果が奏される。   The present invention has a structure as described in claim 2, that is, in a known scaffold tread main body 1 formed by projecting gripping metal fittings 2 on both sides of both end faces, at the center of both end faces, A gap filling material 3 having a side-right triangular shape in which the upper surface 3a is the same horizontal plane as the scaffolding tread main body 1 is additionally fixed, and the gap filling material 3 has a length direction. The width dimension M of the tubular horizontal member a in the scaffolding construction frame A for latching the erection gripping metal fitting 2 is set so as not to exceed the central axis, and the tip is exposed at an upper position thereof. Since it is configured to have a certain size, the same effect as in the case of claim 1 can be obtained.

同時に、隙間埋め材３の長さ方向の幅寸法Ｍを上記のように構成したことにより、足場構築用建枠Ａにおける管状横架材ａが殆ど隠蔽されたような状態、換言すれば、各足場用踏板主体１は殆ど隙間がない状態で連続的に敷設されたような外観を呈するため、前記した間隙部分の存在に基づく事故発生をより一層防止することとなる。 At the same time, since the width dimension M in the length direction of the gap filling material 3 is configured as described above, the state in which the tubular horizontal material a in the scaffold building construction frame A is almost concealed, in other words, Since the scaffolding tread main body 1 has the appearance of being continuously laid with almost no gap, the occurrence of an accident based on the presence of the gap portion is further prevented.

本発明は請求項３に記載のような構成、すなわち、両端面の両側部に架設用つかみ金具２を突設して成る公知の足場用踏板主体１に於いて、当該両端面の中央に、上面3ａを当該足場用踏板主体１と同一水平面とするための水平面とした側面直角三角形状を呈する隙間埋め材３を、付加的に固設すると共に、当該隙間埋め材３は、その長さ方向の幅寸法Ｍが、架設用つかみ金具２を掛け止めるための足場構築用建枠Ａにおける管状横架材ａに対して、その中心軸線を越えない位置にしてかつその上方位置に先端が臨まされる程度の寸法とし、更に、その横幅寸法Ｌを足場用階段Ｂのつかみ金具ｂの間隔より内輪とする寸法に設定するように構成したから、前述した請求項１及び請求項２の場合と同様な作用効果が奏される。 The present invention is configured as described in claim 3, that is, in a well-known scaffold tread main body 1 formed by projecting gripping metal fittings 2 on both sides of both end faces, in the center of both end faces, A gap filling material 3 having a side-right triangular shape in which the upper surface 3a is the same horizontal plane as the scaffolding tread main body 1 is additionally fixed, and the gap filling material 3 has a length direction. The width M of the tubular horizontal member a in the scaffolding construction frame A for holding the erection gripping metal 2 is set so that it does not exceed the central axis, and the tip is exposed at the upper position. In addition, since the width L is set to the dimension that makes the inner ring more than the interval between the grips b of the staircase B for scaffolding, the same as in the case of the first and second aspects described above. The effect is effective.

同時に、隙間埋め材３の横幅寸法Ｌを足場用階段Ｂのつかみ金具ｂの間隔より内輪とする寸法に設定するように構成したから、足場用階段Ｂの取付けに際しても、当該階段Ｂの下端に固設してあるつかみ金具ｂの掛け止めを阻害しないような形態で、当該隙間埋め材３が設けられているため、足場組立て上の齟齬をきたすことがない。   At the same time, since the width L of the gap filling material 3 is set to be an inner ring dimension from the interval between the holding brackets b of the staircase B for scaffolding, the lower end of the staircase B is attached to the staircase B for mounting. Since the gap filling material 3 is provided in a form that does not impede the latching of the gripping metal fittings b that are fixed, there will be no wrinkles on the scaffold assembly.

本発明は請求項４に記載のような構成、すなわち、隙間埋め材３として、一枚の板材を折曲げて成形したものを用いるように構成することにより、当該隙間埋め材３としてスチール材を用いた簡易作業での形成が可能とされる。 According to the present invention, a steel material is used as the gap filling material 3 by using a configuration as described in claim 4, that is, as the gap filling material 3 by using a material obtained by bending a single plate. It is possible to form with the simple work used.

本発明は請求項５に記載のような構成、すなわち、隙間埋め材３として、引き抜き加工に基づき三角形のパイプ状に成形したものを用いるように構成することにより、アルミ材を用いて大量生産に適した合理的かつ安価な形成形態を採ることが可能化される。   The present invention is configured to use the aluminum material for mass production by using the configuration as described in claim 5, that is, the gap filling material 3 is formed into a triangular pipe shape based on a drawing process. It is possible to adopt a suitable rational and inexpensive form of formation.

図１及び図２は本発明に係る足場用踏板を表したものである。 １は足場用踏板主体であって、その長手方向の両端両側部には架設用つかみ金具２が突設してある。 2ａは当該つかみ金具２に設けた固定用掴み金具である。
なお、上記のような形態を具えた足場用踏板主体１は公知技術に属し、本発明はこのような既存の足場用踏板主体１に対して、付加的に施すことを特徴とするものである。 1 and 2 show a footboard for scaffolding according to the present invention. Reference numeral 1 denotes a scaffold tread main body, and erection gripping metal fittings 2 project from both end portions in the longitudinal direction. Reference numeral 2 a denotes a fixing grip provided on the grip 2.
The scaffold tread main body 1 having the above-described form belongs to a known technique, and the present invention is characterized in that it is additionally applied to such an existing scaffold tread main body 1. .

３はその上面3ａを水平面とする側面直角三角形状を呈する隙間埋め材であって、上述した足場用踏板主体１の前端縁1ａの中央部に対して、当該上面3ａが当該足場用踏板主体１の上面と面一状（同一水平面状）に連なるように取付けてある。 そして、その取付け手段であるが、図１に示すようにリベット４の打ち込みに基づき固定化を図ることを通例とするが、その他、螺子止め、溶接、接着剤等に基づき取付けるように構成しても良い。 4aは当該離別との打込み案内用孔を示す。 Reference numeral 3 denotes a gap filling material having a right-sided triangular shape with the upper surface 3a as a horizontal plane, and the upper surface 3a is in relation to the center portion of the front edge 1a of the above-described scaffold tread main body 1 and the scaffold tread main body 1 It is attached so that it may be flush with the upper surface of the same. As shown in FIG. 1, the fixing means is usually fixed based on driving of the rivet 4, but in addition, it is configured to be fixed based on screwing, welding, adhesive or the like. Also good. 4a shows a driving guide hole for the separation.

そして、本発明において上記取付けは付加的に行うと言うことが重要である。 換言すると、足場用踏板主体１の製造時に当該隙間埋め材３を取付ける以外、既に使用に供されている足場用踏板主体１を用いて本発明に係る足場用踏板に改良的に付設してその実施を図ることができる。 これは本発明の大きな特長の一つとするものである。   In the present invention, it is important that the attachment is additionally performed. In other words, except that the gap filling material 3 is attached at the time of manufacturing the scaffold tread main body 1, the scaffold tread main body 1 already in use is used to improve the attachment to the scaffold tread according to the present invention. Implementation is possible. This is one of the major features of the present invention.

図３は本発明に係る足場用踏板における架設用つかみ金具２を、既存の足場構築用建枠Ａにおける管状横架材ａに対して掛け止めた状態を表した使用例を示したものである。 そして、当該既存の足場構築用建枠Ａは所定間隔を保って所要数対向状態で立設すると共に、各対向建枠間に足場用踏板を架設することにより、作業員が作業を行うための足場を構成するものである。   FIG. 3 shows an example of use showing a state in which the mounting bracket 2 for the scaffolding tread according to the present invention is latched to the tubular horizontal member a in the existing building frame A for building a scaffold. . The existing scaffold building construction frame A is erected in the required number of facing states while maintaining a predetermined interval, and a scaffolding tread is erected between the opposing building frames, so that workers can perform work. It constitutes a scaffold.

更に、上述したような組み立て状態にある足場を縦方向に所要段数連結する事により、建築対象物に即した高さとするような積み上げを行うものである。 そして、このような場合、図４に示すように、上位の足場板に上がるための足場用階段Ｂを取付けることが必要とされる。 その取付けは、当該階段Ｂの下端に固設してあるつかみ金具ｂを、上述した建枠Ａの管状横架材ａに対して掛け止めて行うが、この際、前述した足場用踏板１の架設用つかみ金具２の内側に、上記階段Ｂのつかみ金具ｂが位置するように構成されている。   Further, the scaffolds in the assembled state as described above are connected in the vertical direction to the required number of steps so as to be stacked to have a height corresponding to the building object. And in such a case, as shown in FIG. 4, it is necessary to attach the staircase B for scaffolding to go up to an upper scaffold board. The attachment is performed by holding the grip metal fitting b fixed to the lower end of the staircase B with respect to the tubular horizontal member a of the building frame A described above. It is configured so that the grip b of the stairs B is positioned inside the erection grip 2.

本発明に係る足場用踏板は、図３及び図４で表したような使用を可能とするために、本発明の要旨部品たる隙間埋め材３は、下記のような形態を具えたものとするように構成してある。   In order that the footboard for scaffolding according to the present invention can be used as shown in FIGS. 3 and 4, the gap filling material 3, which is a gist of the present invention, has the following form. It is constituted as follows.

すなわち、当該隙間埋め材３の横幅Ｌは上記した階段Ｂのつかみ金具ｂの間に位置させることを可能とするために、当該階段Ｂのつかみ金具ｂの間隔より内輪とする寸法に設定することが重要である。 更に、当該隙間埋め材３の長さ方向の幅Ｍは、架設用つかみ金具２を掛け止めるための足場構築用建枠Ａにおける管状横架材ａの中心軸線を越えずかつ当該管状横架材ａ上にその先端が臨まされる程度の寸法を具えたものとするように構成してある。 これは、複数の足場用踏板を水平方向に並べて架設した際、その互いの隙間埋め材３の端部が接触せず、かつ、あまり離れすぎない程度の間隔を保って対向させることにより、各足場用踏板間の隙間があまり生じないようするためである。   That is, the lateral width L of the gap filling material 3 is set to a dimension that makes the inner ring from the interval of the gripping metal b of the staircase B so that it can be positioned between the gripping metal parts b of the staircase B. is important. Furthermore, the width M in the length direction of the gap filling material 3 does not exceed the central axis of the tubular horizontal material a in the building frame A for constructing a scaffold for latching the mounting grip 2 and the tubular horizontal material. It is configured so as to have a size such that its tip is exposed on a. This is because, when a plurality of scaffolding treads are laid side by side in the horizontal direction, the end portions of the gap filling material 3 are not in contact with each other, and are opposed to each other with an interval that is not too far away. This is to prevent the gap between the footboards for scaffolding from being generated so much.

ところで、上記した隙間埋め材３であるが、その具体的寸法としては、長さ方向の幅Ｍを３２０ｍｍ程度することが、また、その横幅Ｌを４９,５ｍｍ程度することが好ましいが、これに限定されるものではない。   By the way, although it is the above-mentioned gap filling material 3, it is preferable that the width M in the length direction is about 320 mm and that the lateral width L is about 49,5 mm. It is not limited.

更に、当該隙間埋め材３は先細の三角形状に形成することにより、その先端より下面が足場構築用建枠Ａにおける管状横架材ａに接触することなく、その上面側に重なった状態で位置することが出来るように構成してある。   Furthermore, the gap filling material 3 is formed in a tapered triangular shape, so that the lower surface of the gap filling material 3 is positioned on the upper surface side without contacting the tubular horizontal material a in the building frame A for scaffold construction. It is configured to be able to do.

なお、当該隙間埋め材３の側面形状であるが、図５に示すように一枚の板材を折曲げて形成することを通例とするが、図６に示すように引き抜き加工に基づき三角形のパイプ状に形成するように構成して実施することもできる。 前者は主としてスチール材での形成に適しており、また、後者はアルミニウム材での形成に適している。 その他、本発明は前述したような基本的条件が網羅できるものであれば、その形成手段は如何なるものであっても可とする。   In addition, although it is the side surface shape of the said gap filling material 3, it is usual to bend and form one board | plate material as shown in FIG. 5, but it is a triangle pipe based on drawing as shown in FIG. It can also be configured to be formed in a shape. The former is mainly suitable for formation with a steel material, and the latter is suitable for formation with an aluminum material. In addition, as long as the basic conditions as described above can be covered, the present invention can be formed by any means.

本発明に係る足場用踏板は既存の踏板と同様にして使用に供するものである。
そして、足場構築用建枠Ａにおける管状横架材ａに架設した状態では、その隙間埋め材３が当該架設空間を覆い、また、足場用階段Ｂの取付けに際しても、当該階段Ｂの下端に固設してあるつかみ金具ｂの掛け止めを阻害しないような形態とするように、当該隙間埋め材３が構成されているため、このような足場の組立て上に齟齬をきたすことがない。 The scaffold tread according to the present invention is used in the same manner as an existing tread.
When the scaffolding building frame A is installed on the tubular horizontal member a, the gap filling material 3 covers the installation space, and when the scaffolding staircase B is attached, it is fixed to the lower end of the staircase B. Since the gap filling material 3 is configured so as not to obstruct the latching of the gripping metal fittings b provided, no wrinkles are caused on the assembly of such a scaffold.

更に本発明における隙間埋め材３であるが、これは足場用踏板を新規に製造する場合は、その製造作業時に同時的に付設するが、既に流通している踏板に際する実施に当たっては、現場でアダプター的固設作業を施して実施することができる。 すなわち、本発明の実施は既存の踏板に対する実施が可能であるため、実施のための経済的負担性が最小化される。   Further, the gap filling material 3 according to the present invention is provided at the same time when the footboard for scaffolding is newly manufactured, but at the time of the implementation for the footboard that has already been distributed, It can be carried out with an adapter fixing work. That is, since the implementation of the present invention can be performed on existing treads, the economic burden for implementation is minimized.
