Description

本発明は、足場板の側面に設ける幅木を取り付ける縦支柱、及び、それを使用した仮設足場システムに関するもので、更に詳しくは、配管取り付金具とは別に幅木取り付金具を縦支柱に固着した仮設足場用の縦支柱、及び、それを使用した仮設足場システムに関する。 TECHNICAL FIELD The present invention relates to a vertical support for attaching a baseboard provided on the side of a scaffold board, and a temporary scaffolding system using the vertical support. and a temporary scaffolding system using the same.

近年、建設工事現場や土木工事現場の仮設足場において、作業員が足場板から転落したり、工具類が落下したりする事故を防止するために、足場板で構成した通路の両側や、建物の反対側に足場板の外側に幅木を配置するようになっており、この幅木に関する提案も多くなされている。
例えば、特許文献１には、幅木固定金具が開示されているが、足場板に幅木を固定するための挟持具であり、足場板の幅や厚さなどの寸法によらず、幅木を固定できるが、幅木は基本的に支持部の先端の突起部に係止する構成であるため衝撃や振動によって脱落しやすい。
また、特許文献２に開示されている足場用幅木は、縦支柱への固定腕で固定し、横架材には固定腕で固定されているが、機構が複雑であるうえ、固定腕での固定も押圧してであるので、同様に、係止する構成であるため衝撃や振動によって脱落しやすいといった問題点があった。 In recent years, in temporary scaffolding at construction sites and civil engineering sites, in order to prevent accidents such as workers falling from scaffolding boards and tools falling, A skirting board is arranged on the outside of the scaffold board on the opposite side, and many proposals regarding this skirting board have been made.
For example, Patent Literature 1 discloses a baseboard fixing bracket, which is a clip for fixing a baseboard to a scaffold board. However, since the baseboard is basically configured to be locked to the protrusion at the tip of the support, it is likely to fall off due to impact or vibration.
Further, the skirting board for scaffolding disclosed in Patent Document 2 is fixed by a fixed arm to the vertical support and fixed to the horizontal member by a fixed arm. Since it is also fixed by pressing, there is also a problem that it is likely to fall off due to impact or vibration because it is a locking structure.

特開２０１７－２０３２８６号公報JP 2017-203286 A 実用新案登録第３２１５５９１号公報Utility Model Registration No. 3215591

本発明は、上記の問題点に鑑みてなされたもので、建設現場等における足場板の側面に配置する幅木を、強固に且つ簡単に縦支柱に固定できる仮設足場用の縦支柱、及び、それを使用した仮設足場システムを提供しようとするものである。 SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and provides a vertical support for temporary scaffolding capable of firmly and easily fixing baseboards arranged on the side surface of a scaffold board at a construction site or the like to the vertical support; It is intended to provide a temporary scaffolding system using it.

上記課題を解決するために、本発明は、仮設足場における垂直配管である縦支柱において、該縦支柱に配管取り付金具によって水平足場配管を取り付けるとともに該水平足場配管に足場板を取り付け、該足場板の側面部に幅木を設ける縦支柱であって、前記配管取り付金具の近傍上部に、幅木バーを取り付ける幅木取り付金具を固着し、該幅木取り付金具は、縦支柱を囲むように等間隔でＴ字状の４個の嵌合孔を設け、該Ｔ字状の嵌合孔は縦支柱の軸心に向かう短辺と該短辺と直交する長辺からなり、該嵌合孔に幅木端部に設けた下向きに長い幅木係止片を挿入して幅木を固定し、前記４個のそれぞれの嵌合孔は３方向のいずれからも幅木を取り付けることが可能である仮設足場用の縦支柱、及び、それらを組み合わせて仮設足場を構築する仮設足場システムである。 In order to solve the above-mentioned problems, the present invention provides a vertical pillar, which is a vertical pipe in a temporary scaffold, in which a horizontal scaffolding pipe is attached to the vertical pillar by a pipe mounting bracket, a scaffolding plate is attached to the horizontal scaffolding pipe, and the scaffolding is provided. A vertical strut provided with a baseboard on the side surface of a plate, wherein a baseboard mounting bracket for mounting a baseboard bar is fixed to the upper part near the piping mounting bracket, and the baseboard mounting bracket surrounds the vertical strut. Four T-shaped fitting holes are provided at equal intervals, and the T-shaped fitting holes consist of a short side facing the axis of the vertical support and a long side perpendicular to the short side. The baseboard is fixed by inserting a long baseboard locking piece provided at the end of the baseboard into the hole, and the baseboard can be attached to each of the four fitting holes from any of the three directions. and a temporary scaffold system for constructing a temporary scaffold by combining them.

本発明の仮設足場用の縦支柱、及び、それらを組み合わせて仮設足場を構築する仮設足場システムによれば、予め幅木取り付金具が縦支柱に溶接等で固着されているが、今までの仮設足場の縦支柱に幅木取り付金具等が固着した縦支柱が無く、幅木を取り付けるには専用金具や、クランプを使用し固定していた。その為作業時間に時間が掛かったうえ金具やクランプの落下の危険性があり、また、幅木の位置関係など見ながら取り付けないといけない場合があり単純作業ではなかった。これに反して、本発明では縦支柱にすでに幅木取り付金具が固着してある為幅木取り付作業の時間を短縮でき、作業員や工具の落下による危険性の心配がない。更に、取り付の作業においても位置関係など気にすることもなく簡単作業ですむ。また、この予め溶接等で強固に固着された幅木取り付金具の嵌合孔に幅木を組み込んでいるので、幅木が縦支柱から外れることがなく安全である。なお、仮設足場等の現場で足場を組み立てる以前に、取り付けも幅木側の幅木係止片を嵌合孔に挿入するだけの簡単な操作で取り付けることができる。 According to the vertical pillars for temporary scaffolding of the present invention and the temporary scaffolding system for constructing a temporary scaffold by combining them, the baseboard mounting hardware is fixed to the vertical pillars in advance by welding or the like. There was no vertical support to which baseboard mounting metal fittings were fixed to the vertical support of the scaffold, and special metal fittings or clamps were used to attach the baseboard. Therefore, it took a long time to work, and there was a danger that the metal fittings and clamps would fall off. On the other hand, in the present invention, since the baseboard mounting hardware is already fixed to the vertical support, the time required for the baseboard mounting work can be shortened, and there is no risk of the worker or tool falling. Furthermore, the mounting work can be done easily without worrying about the positional relationship. In addition, since the baseboard is incorporated into the fitting hole of the baseboard mounting bracket which is firmly fixed in advance by welding or the like, the baseboard is not detached from the vertical support and is safe. Before assembling the temporary scaffolding on site, it can be attached by a simple operation of inserting the baseboard locking piece on the side of the baseboard into the fitting hole.

以下に本発明の仮設足場用の縦支柱、及び、それを使用した仮設足場システムの好適な実施例を図面に沿って説明する。
先ず、図１に示すように、本発明の実施例の仮設足場は、縦支柱１に配管取り付金具６と幅木取り付金具７とを溶接等で固着したものである。配管取り付金具６は従来の仮設足場と同様に、水平足場配管２が接続装置２１を介して縦支柱１に固定されるが、本発明の実施例では、更に、幅木取り付金具７が固定されるのが特徴の１つである。 A preferred embodiment of the vertical support for temporary scaffolding of the present invention and a temporary scaffolding system using the same will be described below with reference to the drawings.
First, as shown in FIG. 1, the temporary scaffolding according to the embodiment of the present invention is constructed by fixing a pipe fitting 6 and a baseboard fitting 7 to a vertical post 1 by welding or the like. As with the conventional temporary scaffolding, the pipe fittings 6 are fixed to the vertical pillars 1 through the connection devices 21 by the horizontal scaffolding pipes 2, but in the embodiment of the present invention, the skirting board fittings 7 are further fixed. One of the features is that

図２は本発明の縦支柱を組み合わせた仮設足場を構築したシステムの図で、図２(ａ)は、縦支柱１の１８００mm,２７００mm,３６００mmの標準サイズを連結して適宜の高さの縦支柱１を形成し、これらを適宜組み合わせ１８００mm毎に足場板４を水平足場配管２に掛け渡して通路を形成するとともに、手摺り部３を取り付け、足場板４で形成する通路の両側、或いは建物の外側に幅木５を組み込んである。図２で符号１１は継ぎ目であるが、図２(ｂ)に示すように、適宜、継ぎ目１１でつなぎ合わせて所望の高さの縦支柱を形成することができる。
本発明の仮設足場システムの特徴は、従来の縦支柱１の配管取り付金具６の８cm(５～２５cm)程度の上部適所に、複数の方向に幅木が取り付け可能な幅木取り付金具７を予め溶接等で固着したことを特徴の１つとしたものである。 FIG. 2 is a diagram of a system in which a temporary scaffolding is constructed by combining the vertical struts of the present invention. FIG. Supports 1 are formed, scaffolding boards 4 are strung over horizontal scaffolding pipes 2 every 1800 mm by appropriately combining them to form a passage, and a handrail part 3 is attached to both sides of the passage formed by the scaffolding boards 4 or a building. A skirting board 5 is incorporated on the outside of the . Reference numeral 11 in FIG. 2 denotes a joint, and as shown in FIG. 2(b), it is possible to form a vertical strut having a desired height by joining the joints at the joint 11 as appropriate.
A feature of the temporary scaffolding system of the present invention is that baseboard mounting brackets 7, which can be attached to baseboards in multiple directions, are installed in appropriate places about 8 cm (5 to 25 cm) above pipe mounting brackets 6 of conventional vertical posts 1. One of the features is that they are fixed in advance by welding or the like.

［水平足場配管２の接続装置２１］
したがって、図２(ａ),(ｂ)に示すように、配管取り付金具６と幅木取り付金具７とは対応して予め配置されている。ここで、図３に示すように、配管取り付金具６に接続装置２１を介し固定キー２１１を打ち込むことによって縦支柱１に固定し、この配管取り付金具６に水平足場配管２を組み付け、この水平足場配管２に足場板４を取り付ける。
この際に留意すべきことは、接続装置２１に打ち込む固定キー２１１が縦支柱１の管外周から少し離れた位置にする必要があり、このようなタイプの接続装置を選ぶ必要がある。これは、本発明で配管取り付金具６の少し上に幅木取り付金具７が配置しているために、固定キー２１１を打ち込むために従来のような管外周に密着した位置であると固定キー２１１の打ち込み作業の邪魔になるからである。
本実施例では図３に示す接続装置２１を使用したが、この接続装置２１を図４、図５、図６、図７に沿って更に詳しく説明する。
図４は、配管取り付金具６に接続金具２を組み込む前の斜視図であるが、固定キー２１１は縦支柱１の管外周１２から少し離れた位置にして固定キー２１の打ち込み作業を容易にする必要があり、このために、図５に示すように、管外周１２と固定キー２１１との間に可動部材２１２を介在させ、固定キー２１１を縦支柱１から離している。
組み立てに際しては、図５、図６、図７に示すように、先ず、接続装置２１の先端に設けた歯形の嵌合部２１３を、配管取り付金具６の嵌合孔６１に嵌合する(図６)。次に、この嵌合状態を固定するために、可動部材２１２が固定キー２１１の打ち込みによって、可動部材２１２の斜行面２１５と長孔２１６に沿って可動部材２１２が管外周１２側に移動し、可動部材２１２の管外周１２側の先端の押出部２１４が接続装置２１の本体から突出することにより、接続装置２１及び水平足場配管２が縦支柱１に強固に固定される。なお、図５、図６における固定ピン２１７に設けられた板バネ２１８は、接続装置２１が仮設足場から外されている場合には可動部材を内側に押し込んでおくものである。 [Connection device 21 for horizontal scaffold pipe 2]
Therefore, as shown in FIGS. 2(a) and 2(b), the pipe mounting bracket 6 and the baseboard mounting bracket 7 are pre-arranged so as to correspond to each other. Here, as shown in FIG. 3, the pipe mounting bracket 6 is fixed to the vertical support 1 by driving a fixing key 211 through the connection device 21, and the horizontal scaffolding pipe 2 is assembled to the pipe mounting bracket 6. A scaffolding board 4 is attached to a horizontal scaffolding pipe 2. - 特許庁
At this time, it should be noted that the fixing key 211 to be driven into the connection device 21 needs to be positioned slightly away from the outer circumference of the pipe of the vertical support 1, and it is necessary to select such a type of connection device. This is because the baseboard mounting bracket 7 is arranged slightly above the pipe mounting bracket 6 in the present invention, so that the fixing key 211 is placed in close contact with the outer periphery of the pipe as in the conventional case. This is because it interferes with the driving operation of 211.
Although the connection device 21 shown in FIG. 3 is used in this embodiment, this connection device 21 will be described in more detail with reference to FIGS.
FIG. 4 is a perspective view of the pipe fitting 6 before the connection fitting 2 is assembled. For this purpose, as shown in FIG.
When assembling, as shown in FIGS. 5, 6, and 7, first, the tooth-shaped fitting portion 213 provided at the tip of the connection device 21 is fitted into the fitting hole 61 of the pipe fitting 6 ( Figure 6). Next, in order to fix this fitted state, the movable member 212 moves toward the pipe outer circumference 12 along the oblique surface 215 and the long hole 216 of the movable member 212 by driving the fixed key 211 . , the connecting device 21 and the horizontal scaffolding pipe 2 are firmly fixed to the vertical support 1 by the extruding portion 214 at the end of the movable member 212 on the pipe outer circumference 12 side protruding from the main body of the connecting device 21 . A leaf spring 218 provided on the fixing pin 217 in FIGS. 5 and 6 pushes the movable member inward when the connecting device 21 is removed from the temporary scaffolding.

［幅木５］
次に、図８、図１１に示すように、前記足場板の側面の必要箇所に、作業員の安全や工具の落下防止のために垂直に幅木５を取り付けるが、本実施例での幅木５は垂直面５２と水平面５３とからなる断面Ｌ字状で、幅木５の両端には、幅木取り付金具７の嵌合孔７１に、挿入する下方に向かう幅木係止片５１が設けられている。
ここで、幅木５の全体形状はＬ字状ではなく、単純に平面でもよいが、幅木５の下辺に隙間が生じることを防ぐため、Ｌ字状の形状が好ましい。また、幅木係止片５１は、幅木５とは別体にして後から幅木５の両端に固着するようにしてもよい。
また、幅木係止片５１の機能も嵌合孔７１に単に上から下方向に挿入し、抜くときは単に上方にあげれば抜ける構造でもよく、或いは、挿入が容易であるが着脱は困難な構造、例えば、傘のストッパー構造のような傾斜面と水平面とバネからなり、幅木係止片５１の挿入時はバネ力に抗して斜面に沿って移行し、着脱時は水平面が嵌合孔７１に止まるストッパー構造でもよい。 [Baseboard 5]
Next, as shown in FIGS. 8 and 11, baseboards 5 are attached vertically to the necessary portions of the side surfaces of the scaffolding board for the safety of workers and the prevention of tools from falling. The tree 5 has an L-shaped cross section consisting of a vertical surface 52 and a horizontal surface 53. At both ends of the baseboard 5, baseboard locking pieces 51 are inserted into fitting holes 71 of the baseboard mounting bracket 7 and directed downward. is provided.
Here, the overall shape of the baseboard 5 is not L-shaped, and may be simply flat. Further, the baseboard locking pieces 51 may be separated from the baseboard 5 and fixed to both ends of the baseboard 5 afterward.
Also, the function of the baseboard locking piece 51 may be such that it is simply inserted into the fitting hole 71 from above downward and removed by simply pulling it upward, or it may be easy to insert but difficult to remove. Structure, for example, an umbrella stopper structure consisting of an inclined surface, a horizontal surface, and a spring, when the baseboard locking piece 51 is inserted, it moves along the slope against the spring force, and when it is removed, the horizontal surface is engaged. A stopper structure that stops at the hole 71 may be used.

［幅木取り付金具７］
前述した幅木を縦支柱１に取り付ける幅木取り付金具７を図９、図１０に沿って説明する。
図９、図１０に示すように、幅木取り付金具７は、４個の嵌合孔７１が設けられるが、この嵌合孔７１は縦支柱１（或いは縦支柱用孔７２）を囲むように等間隔でＴ字状の４個の嵌合孔７１を設け、この嵌合孔７１は縦支柱１の軸心Ｘに向かう短辺７１１とこれと直交する長辺７１２とからなるＴ字状であり、このＴ字状は上下を圧縮した形状ではあるが、これは幅木５の組み込み方向を２方向から３方向に増やすための形状である。
すなわち、図３及び図１１に示すように、嵌合孔７１に幅木端部に設けた下向きに長い係止片５１を挿入して幅木５を固定し、図１０に示すように、４個の嵌合孔７１のそれぞれには縦支柱１の左右側と直交する３方向のいずれからも幅木５の幅木係止片５１が挿入可能であり、幅木取り付金具７の嵌合孔７１は、縦支柱１の外周に等間隔（９０度の間隔でもある)に４個設けられているので、結局、３方向×４＝１２方向に幅木５が取り付けることができる。 [Baseboard mounting bracket 7]
The baseboard mounting hardware 7 for mounting the above-described baseboard to the vertical support 1 will be described with reference to FIGS. 9 and 10. FIG.
As shown in FIGS. 9 and 10, the baseboard mounting bracket 7 is provided with four fitting holes 71. The fitting holes 71 are formed so as to surround the vertical support 1 (or the vertical support hole 72). Four T-shaped fitting holes 71 are provided at equal intervals, and these fitting holes 71 are T-shaped with a short side 711 facing the axis X of the vertical support 1 and a long side 712 perpendicular thereto. Although this T-shape is a shape in which the top and bottom are compressed, this is a shape for increasing the mounting direction of the baseboard 5 from two to three.
That is, as shown in FIGS. 3 and 11, the baseboard 5 is fixed by inserting a locking piece 51 provided at the end of the baseboard into the fitting hole 71, and as shown in FIG. The baseboard locking pieces 51 of the baseboard 5 can be inserted into the respective fitting holes 71 from any of the three directions orthogonal to the left and right sides of the vertical support 1, and the fitting holes 71 of the baseboard mounting brackets 7 can be inserted. 71 are provided on the outer periphery of the vertical support 1 at equal intervals (also at intervals of 90 degrees), so that the baseboards 5 can be attached in 3 directions×4=12 directions.

[組み立て完了した構成]
図１１は、図１の配管取り付金具６に水平足場配管２を取り付け、更に足場板４を取り付けた仮設足場において、幅木取り付金具７の１つの嵌合孔７１に幅木５の幅木係止片５１を挿入して仮設足場を完成させたものであり、仮設足場全体としては、図２に示すように、水平足場配管２の配管取り付金具６と一対で幅木取り付金具７が予め溶接等で固着されており、このような一対の配管取り付金具６と幅木取り付金具７と固着した仮設足場システムとすることで、従来のように幅木を取り付けるには専用金具や、クランプを使用し固定するのではなく、予め幅木取り付金具７が固着しているので、幅木５の組み込みも容易となる。 [Assembled configuration]
FIG. 11 shows a temporary scaffold in which a horizontal scaffold pipe 2 is attached to the pipe mounting bracket 6 of FIG. A temporary scaffolding is completed by inserting locking pieces 51. As a whole temporary scaffolding, as shown in FIG. It is preliminarily fixed by welding or the like, and the provision of a temporary scaffolding system in which the pair of pipe fittings 6 and the baseboard mounting fittings 7 are fixed to each other makes it possible to attach the baseboards as in the past without special metal fittings, Since the baseboard mounting bracket 7 is fixed in advance instead of using a clamp, the baseboard 5 can be easily incorporated.

本発明の実施例は、以上のような構成であるので、仮設足場用の縦支柱、及び、それらを組み合わせて仮設足場を構築する仮設足場システムにおいて、予め幅木取り付金具が縦支柱に溶接等で固着されているが、今までの仮設足場の縦支柱に幅木取り付金具が溶接等で固着した縦支柱が無く、幅木を取り付けるには専用金具や、クランプを使用し固定していた。その為作業時間に時間が掛かったうえ金具やクランプの落下の危険性があった。また、幅木の位置関係など見ながら取り付けないといけない場合があり単純作業ではなかった。また、この幅木取り付金具の嵌合孔に幅木を組み込んでいるので、幅木が縦支柱から外れることがなく安全である。 Since the embodiment of the present invention is configured as described above, in a temporary scaffolding system for constructing a temporary scaffold by combining vertical posts for temporary scaffolding, baseboard mounting brackets are previously welded to the vertical posts. However, there is no vertical support where baseboard mounting hardware is fixed to the vertical support of temporary scaffolding by welding, etc., and special hardware or clamps are used to attach baseboards. As a result, it took a long time to work, and there was a danger that the metal fittings and clamps would fall. In addition, it was not a simple task because it was sometimes necessary to install while looking at the positional relationship of the baseboards. In addition, since the baseboard is incorporated in the fitting hole of the baseboard mounting bracket, the baseboard does not come off from the vertical support and is safe.

本発明では縦支柱にすでに幅木取り付金具が固着してある為に、幅木取り付作業の時間を短縮でき、作業員や工具の落下による危険性の心配がない。更に、取り付の作業においても位置関係など気にすることもなく簡単作業ですむ。なお、仮設足場を組み立てる以前に取り付けも幅木側の幅木係止片を嵌合孔に挿入するだけの簡単な操作で取り付けることができる。また、現場以外で取り付けも幅木側の幅木係止片を嵌合孔に挿入するだけの簡単な操作で取り付けることができる。
なお、本発明の特徴を損なうものでなければ、上記の実施例に限定されるものでないことは勿論であり、例えば、幅木５も断面略Ｌ字状以外の平板等でもよく、また、幅木５を幅木取り付金具７の嵌合孔７１に挿入し固定できるものであれば、図８や図１１の形以外のものでも良い。 In the present invention, since the metal fittings for mounting the baseboard are already fixed to the vertical support, the time for mounting the baseboard can be shortened, and there is no concern about the danger of falling workers or tools. Furthermore, the mounting work can be done easily without worrying about the positional relationship. Before assembling the temporary scaffolding, it can be attached by a simple operation of inserting the baseboard locking piece on the side of the baseboard into the fitting hole. In addition, it can be installed by a simple operation of inserting the baseboard locking piece on the side of the baseboard into the fitting hole even when it is installed outside the site.
It goes without saying that the present invention is not limited to the above embodiments as long as it does not impair the characteristics of the present invention. Any shape other than that shown in FIGS. 8 and 11 may be used as long as the tree 5 can be inserted into the fitting hole 71 of the baseboard mounting bracket 7 and fixed.
