Description

【０００１】
【発明の属する技術分野】
本発明は、土木、建築などの工事分野において、建築物の外壁などにそって設置する建築用等の枠組足場の手摺に関するものである。
【０００２】
【従来の技術】
土木、建築の建設工事現場において、枠組足場の建枠を上下方向、左右方向に所要数連結して枠組足場を構築して施工しているが、その組み立てや解体では作業員はその最上段の足場の上に乗ってその作業を行っている。
【０００３】
しかし、最上段の足場には、その周囲に安全のための柱や手摺が無いことがあり、作業に恐怖感を憶えたり、転落などの危険性があった。
【０００４】
【先行技術文献】
そこで、出願人は、上記のような枠組足場の安全手摺について特許調査を行った結果、特開平７−２７９４０４号公報、特開２００２−２２０９２６号公報、特開２００２−２０６３３６号公報が検索できた。
【０００５】
【発明が解決しようとする課題】
これらについて検討したところ、これらの先行技術資料はいずれも、足場用建枠の両側の縦材に手摺を取着して、作業の安全をはかることが提案されている。しかし、手摺は、建枠の縦材の所定の位置でクランプするようにしているが、これらの手摺同士を連結していない。
【０００６】
このように、枠組足場に手摺が配設されているが、建枠を順次組み立てたり、分解する際には手摺はぐらぐらして安全性に乏しい。そのため、隣接する手摺同士を締結金具で締結して強化することも行われているが、迅速に建枠を組み立てたり、解体しにくくなるとともに、その作業に手間がかかるもので、簡易、迅速に安全な枠組足場を組み立て、解体できる建築用の枠組足場を開発するのが課題であった。
【０００７】
【課題を解決するための手段】
本発明は、上記のような点に鑑みたもので、上記の課題を解決するために、建築用等の枠組足場の建枠の脚柱に手摺の支柱部を昇降可能に配設するとともに、枠組足場の組み立て、解体時にこの手摺の支柱部の昇降に対応可能に上記手摺の支柱部間に安全柵用の横桟を屈曲可能にリンク材を介して支柱部間に接続自在に設け、手摺の支柱部の昇降に対応してリンク部材が支柱部側から側方に突き出て斜めに伸び、隣の支柱部が上昇すると突き出たリンク部材が元の状態の支柱部側にへこんで、手摺の横桟が常に支柱部間に接続した状態を維持できるように形成したことを特徴とする建築用等の足場の手摺を提供するにある。
【０００８】
【発明の実施の形態】
本発明の建築用等の足場の手摺は、建築用等の枠組足場の建枠の脚柱に手摺の支柱部を昇降可能に配設するとともに、枠組足場の組み立て、解体時にこの手摺の支柱部の昇降に対応可能に上記手摺の支柱部間に安全柵用の横桟を屈曲可能にリンク材を介して支柱部間に接続自在に設け、手摺の支柱部の昇降に対応してリンク部材が支柱部側から側方に突き出て斜めに伸び、隣の支柱部が上昇すると突き出たリンク部材が元の状態の支柱部側にへこんで、手摺の横桟が常に支柱部間に接続した状態を維持できるように形成したことを特徴としている。
【０００９】
土木や建築用等の枠組足場１は、図１（ａ）、（ｂ）のように従来の枠組足場用の建枠２を上下方向、左右方向に連結し、所要の高さ、幅に組み立てて構築できるもので、その建枠２に手摺３を昇降摺動可能として枠組足場１を安全に組み立て、解体作業を行えるようにしている。
【００１０】
手摺３は、図１、図２のようにその支柱部４を細長い箱枠状に形成し、この支柱部４の両側の平行の垂直材５に所定の間隔で水平材６を架設し、図３のように水平材６にガイドローラの挟着摺動材７を所定の角度のほぼハの字状に傾けて軸着し、その間に建枠２の脚柱８に挟着して所定距離にわたって昇降摺動可能としているものである。
【００１１】
そして、このような支柱部４の中程部に、図１、図２のようにストッパー９を配設しているもので、ストッパー９は図４（ａ）、（ｂ）のように支柱部４の両側の垂直材５に水平材１０を配設し、この水平材１０に所要の間隔、建枠２の脚柱８よりも広い間隔で左右対称状にストッパー部材１１をやや後方側に突き出してコイルスプリング等のばね１２に抗して開閉可能に配設し、手摺３を上方側に移動するときは建枠２の横材１３の端部に当接しても自由に開いて通過し、手摺３を下方に移動するときは建枠２の横材１３の端部に当接すると横材１３の側面にそって引っ掛けて係止して組み付けておけるようにしている。
【００１２】
上記ストッパー部材１１には、図４（ａ）、（ｂ）のように左右のストッパー部材１１の下方側に建枠２に当たらないようにＶ字状にリンク材１４を接続してその接合部１５に押上材１６を取り付け、押上材１６をばね１２に抗して押し上げることによって、左右のストッパー部材１１を左右に押し拡げ、係止材１３を通過して手摺３を上方や下方に自由に移動できるようにして組み立て、解体を容易にできるようにしている。
【００１３】
上記したストッパー９としては、公知のクランプ材等を使用して建枠２の所要の位置に係止させるようにもできる。
【００１４】
このように形成した手摺３の支柱部４間には、図１、図２のように安全柵用の横棧１７を上下二段等の多段状にボルト、ナットや公知の着脱手段を介して架設するようにしているとともに、隣り合う手摺３のぐらつきを防止できるように精度よく密接して取着するようにしている。
【００１５】
上記した横棧１７は、伸縮自在にそれぞれの支柱部４の垂直材５に接続して枠組足場１の建枠２の組み立て、解体時に取り外す必要がなく、支柱部４間を接続できるようにしているもので、たとえば図１、図２に示すように手摺３の昇降量に対応して横棧１７の一端部側を屈曲自在にリンク材１８を介して支柱部４間に接続し、常に支柱部４間に横棧１７を架設状態とした安全柵としている。
【００１６】
上記横棧１７の伸縮手段としては、図１、図２のようにリンク部材１８が側方に突き出て斜めに伸び、隣りの支柱部４を上昇すると、突き出たリンク部材１８は元の状態にへこみ、横棧１７が水平に支柱部４間に架設するようにできる。
【００１７】
この横棧の接続手段や取着手段としては、周知のボルト、ナットで行なうことができるが、着脱自在に茄子環接続、蝶番ボルト・柄付きナット接続、回転して掛け外しできる締め付けボルト接続などとするのが作業効率を向上できて好ましい。
【００１８】
【実施例】
図１以下は、本発明の一実施例を示すものである。所定の高さ、幅に組み立てる枠組足場１の建枠２の脚柱８に、手摺３の上記した細長い箱枠状の支柱部４に配設した上下の挟着摺動材７の左右のガイドローラをそれぞれ挟着して手摺３を配設するようにしたもので、この支柱部４の左右の垂直材５に横棧１７を上下二段にそれぞれリンク接続して枢着して接続し、隣り合う支柱部４を強化するようにしている。
【００１９】
そして、手摺３の支柱部４を建枠２間に架設した足場板１９に登載して図１、図２のように建枠２にそって上方に押し上げると、支柱部４は建枠２の脚柱８にそって上昇し、建枠２の横材１３にストッパー９が通過した状態で停止すると、ストッパー部材１１がばね１２で引き寄せられて閉じて横材１３に引っ掛けて係止させることができる。
【００２０】
また、支柱部４の側部の横棧１７は、リンク部材１８が側方に突き出て斜めに伸び、隣りの支柱部４を上昇すると、突き出たリンク部材１８は元の状態にへこみ、横棧１７が水平に支柱部４間に架設した状態となって安全に足場板１９を順次組み上げていくようにしている。
【００２１】
したがって、枠組足場１を組み立てるのに、たとえば図１、図２のように先ず最下段となる建枠２の脚柱８の間に足場板１９を架設し、その足場板１９に登載して手摺３の挟着摺動材７を上記建枠２の脚柱８に挿入して支柱部４を挟着するようにして装着していく。そして、この支柱部４の両側の垂直材５に予め一端を取り付けた横棧１７、リンク材１８を図１、図２のようにリンク接続し、横棧１７による安全柵を形成していく。
【００２２】
ついで、上記した建枠２の上に上位となる建枠２を図１、図２のように組み立て、足場板１９を持ち上げて上段に架設し、上記したように手摺３の支柱部４を建枠２間に架設した足場板１９に登載して建枠２にそって上方に押し上げて、手摺３を建枠２の上段に移動していく。このようにして建枠２の上に順次建枠２、足場板１９を組み上げて、手摺３を順次組み立てる建枠２の上方へ移動していって、常に横棧１７を支柱部４間に接続した状態で組み立て作業を行うことができるものである。
【００２３】
また、枠組足場１を解体するにあっても、逆に、組み立てた最上段の建枠２の手摺３のストッパー１６を押して支柱部４を図１、図２のように下げていき、上位の建枠２を順次解体していくことができるもので、この際にも、手摺３の横棧１７は常に支柱部４間に接続した状態を維持できるので、安全に作業を遂行することができる。
【００２４】
このように手摺３の支柱部４間に常に横棧１７を接続した状態で枠組足場１の組み立て、解体の作業ができ、かつ支柱部４を隣り合う横棧１７で補強できて支柱部４のぐらつきも防止できるものである。
【００２５】
また、支柱部４を細長い箱枠状として建枠２の脚柱８を抱き込みように挟着しているので、手摺３がはずれるおそれがなく、安全に維持することができるものである。
【００２６】
【発明の効果】
以上のように本発明にあっては、建築用等の枠組足場の建枠の脚柱に手摺の支柱部を昇降可能にそれぞれ配設して、これらの支柱部間に手摺の安全柵用の横棧を手摺の支柱部の昇降に対しても、常に支柱部間に横棧を接続した状態の安全柵とでき、しかも隣り合う支柱部を横棧で補強できて支柱部のぐらつきを防止できて安全に枠組足場の組み立て、解体作業を行うことができる。
【００２７】
特に、安全柵用の横桟を屈曲可能にリンク材を介して支柱部間に接続自在に設け、手摺の支柱部の昇降に対応してリンク部材が支柱部側から側方に突き出て斜めに伸び、隣の支柱部が上昇すると突き出たリンク部材が元の状態の支柱部側にへこんで、手摺の横桟が常に支柱部間に接続した状態を維持できるように形成したことによって、安全柵の横桟をリンク材を介して支柱部間に接続すると、支柱部の側部の横棧はリンク部材が側方に突き出て斜めに伸び、隣りの支柱部を上昇すると、突き出たリンク部材は元の状態にへこみ、横棧が水平に支柱部間に架設できて、上記したように常に支柱部間に横棧を接続した状態の安全柵とでき、安全に作業できる。
【００２８】
また、手摺の安全柵用の横棧を屈曲自在にリンク接続して支柱部間に上下二段として装着することによって、手摺の安全柵の横棧を上下二段として上記のように接続した状態に維持することができる。
【００２９】
さらに、手摺の支柱部部を細長い箱枠状に形成して、この細長い箱枠状の支柱部内に挟着摺動材を配設して枠組足場の建枠の脚柱を挟着して昇降可能に形成することによって、手摺の支柱部を建枠の脚柱からはずれなく、安全に作業を行うようにできるものである。
【００３０】
またさらに、手摺の支柱部に手摺を所定の位置に係止可能にストッパーを設け、手摺を昇降するときにストッパーを解放自在に形成し、所定位置に停止するときにストッパーが枠組足場の建枠に突設した横棧等の係止材に引っ掛けて係止するように形成することによって、建枠の脚柱にそって手摺の支柱部を昇降することで枠組足場を所定の位置に組み上げたり、分解することができ、簡易、迅速に作業を遂行できるものである。

Therefore, as a result of conducting a patent survey on the safety scaffolding of the framework scaffold as described above, the applicant was able to search for JP-A-7-279404, JP-A-2002-220926, and JP-A-2002-206336. .
[0005]
[Problems to be solved by the invention]
When these were examined, it has been proposed that all of these prior art documents secure the work by attaching handrails to the vertical members on both sides of the scaffolding frame. However, the handrail is clamped at a predetermined position of the vertical member of the building frame, but these handrails are not connected to each other.
[0006]
As described above, the handrails are disposed on the frame scaffolding. However, when the building frames are sequentially assembled or disassembled, the handrails sway and have poor safety. For this reason, the adjacent handrails are tightened and tightened with fastening brackets, but it is difficult to quickly assemble or disassemble the building frame, and it takes time and effort to perform the work easily and quickly. The challenge was to develop an architectural framework scaffold that could assemble and disassemble a safe framework scaffold.
[0007]
[Means for Solving the Problems]
The present invention has been made in view of the above points, and in order to solve the above-described problems, a handrail column is disposed on a pedestal of a building frame of a frame scaffold such as a building so as to be movable up and down. A side rail for a safety fence can be bent between the support rails of the handrail so that it can be moved up and down at the time of assembly and disassembly of the frame scaffolding. Corresponding to the lifting and lowering of the column part, the link member protrudes sideways from the column part and extends diagonally, and when the adjacent column part rises, the protruding link member is dented to the original column part side, and the handrail An object of the present invention is to provide a handrail for a scaffold for building or the like, characterized in that the horizontal rail is formed so as to be always connected between the columns .
[0008]
DETAILED DESCRIPTION OF THE INVENTION
The handrail of the scaffolding for construction of the present invention is arranged such that the pillar portion of the handrail can be moved up and down on the building pillar of the framework scaffolding for construction and the like, and the pillar portion of the handrail at the time of assembling and dismantling the frame scaffolding A horizontal rail for the safety fence can be bent between the support rails of the handrail so that it can be connected to the support rails via a link material so that the link member can be connected to the support rail. Protruding from the column side to the side and extending diagonally, when the adjacent column part rises, the protruding link member is dented to the column state of the original state, and the state where the rail of the handrail is always connected between the column parts It is characterized by being formed so that it can be maintained .
[0009]
As shown in Figs. 1 (a) and 1 (b), the framework scaffold 1 for civil engineering and construction is assembled to the required height and width by connecting the conventional framework scaffold 2 to the vertical and horizontal directions. The handrail 3 can be moved up and down on the building frame 2 so that the frame scaffold 1 can be safely assembled and dismantled.
[0010]
As shown in FIGS. 1 and 2, the handrail 3 is formed with a column portion 4 in an elongated box frame shape, and horizontal members 6 are installed at predetermined intervals on parallel vertical members 5 on both sides of the column portion 4. As shown in FIG. 3, the guide roller sandwiching sliding member 7 is tilted in a substantially C-shape with a predetermined angle on the horizontal member 6 and is axially attached to the horizontal member 6. It can be moved up and down.
[0011]
In addition, a stopper 9 is disposed in the middle part of the column part 4 as shown in FIGS. 1 and 2, and the stopper 9 is a column part as shown in FIGS. 4 (a) and 4 (b). The horizontal member 10 is disposed on the vertical member 5 on both sides of the four, and the stopper member 11 is protruded slightly rearward in a symmetrical manner at a predetermined interval, wider than the pillars 8 of the building frame 2. It is arranged to be openable and closable against a spring 12 such as a coil spring, and when moving the handrail 3 upward, it can freely open even if it abuts against the end of the cross member 13 of the building frame 2, When the handrail 3 is moved downward, when it is in contact with the end of the cross member 13 of the building frame 2, it is hooked along the side surface of the cross member 13 to be locked and assembled.
[0012]
4A and 4B, the link member 14 is connected to the stopper member 11 in a V shape so as not to hit the building frame 2 on the lower side of the left and right stopper members 11. The push-up member 16 is attached to 15 and the push-up member 16 is pushed up against the spring 12 to expand the left and right stopper members 11 to the left and right, pass through the locking member 13 and freely move the handrail 3 upward and downward. It can be moved, assembled and disassembled easily.
[0013]
As the stopper 9 described above, a known clamping material or the like can be used to lock the building frame 2 at a required position.
[0014]
Between the support pillars 4 of the handrail 3 formed in this way, as shown in FIG. 1 and FIG. 2, a horizontal fence 17 for a safety fence is formed in multiple stages such as upper and lower two stages through bolts, nuts and known attaching / detaching means. In addition to being constructed, it is closely attached with high precision so as to prevent wobble of adjacent handrails 3.
[0015]
The above-mentioned recumbent ridges 17 are connected to the vertical members 5 of the respective column portions 4 so as to be freely stretchable, so that it is not necessary to remove them when assembling and dismantling the building frame 2 of the frame scaffold 1 so that the column portions 4 can be connected. For example, as shown in FIGS. 1 and 2, one end side of the horizontal bar 17 is flexibly connected between the column parts 4 via the link members 18 in accordance with the amount of elevation of the handrail 3, and is always A safety fence with a horizontal beam 17 installed between the parts 4 is used.
[0016]
As the expansion / contraction means of the horizontal bar 17, as shown in FIGS. 1 and 2, the link member 18 protrudes sideways and extends obliquely, and when the adjacent column part 4 is lifted, the protruding link member 18 returns to its original state. The dents and the recumbent rods 17 can be installed between the support columns 4 horizontally.
[0017]
As the connecting means and attaching means of this horizontal anchor, it can be done with well-known bolts and nuts, but it can be detachably connected with an insulator ring, a hinge bolt / handled nut connection, a tightening bolt connection that can be rotated and detached, etc. It is preferable that the working efficiency can be improved.
[0018]
【Example】
FIG. 1 and subsequent figures show an embodiment of the present invention. The left and right guides of the upper and lower sandwiched sliding members 7 disposed on the above-mentioned elongated box-frame-like column portions 4 of the handrail 3 on the leg columns 8 of the building frame 2 of the frame scaffold 1 assembled to a predetermined height and width. The handrails 3 are disposed by sandwiching the rollers, and the horizontal rods 17 are linked and connected to the vertical members 5 on the left and right sides of the support column 4 in two upper and lower stages. Adjacent struts 4 are strengthened.
[0019]
Then, when the column 4 of the handrail 3 is placed on the scaffolding plate 19 installed between the building frames 2 and pushed upward along the building frame 2 as shown in FIGS. 1 and 2, the column 4 is attached to the building frame 2. When the stopper 9 is raised along the pedestal 8 and stopped in a state where the stopper 9 has passed through the cross member 13 of the building frame 2, the stopper member 11 is attracted by the spring 12 to be closed and hooked on the cross member 13 to be locked. it can.
[0020]
Moreover, when the link member 18 protrudes to the side and extends obliquely and the adjacent support member 4 is lifted, the link member 18 protrudes into the original state, and the link member 18 on the side portion of the support member 4 dents into the original state. The scaffolding plate 19 is sequentially assembled safely in a state where 17 is horizontally installed between the support columns 4.
[0021]
Therefore, for assembling the frame scaffold 1, for example, as shown in FIGS. 1 and 2, first, a scaffold plate 19 is erected between the pillars 8 of the lowermost building frame 2, and is placed on the scaffold plate 19 to be handrailed. 3 is inserted into the pillars 8 of the building frame 2 so as to sandwich the support column 4. Then, the horizontal rod 17 and the link material 18 having one end attached in advance to the vertical member 5 on both sides of the support column 4 are linked as shown in FIGS. 1 and 2 to form a safety fence by the horizontal rod 17.
[0022]
Next, the upper building frame 2 is assembled on the above-described building frame 2 as shown in FIGS. 1 and 2, the scaffolding plate 19 is lifted and installed on the upper stage, and the column part 4 of the handrail 3 is built as described above. It is placed on the scaffolding plate 19 installed between the frames 2 and pushed upward along the building frame 2 to move the handrail 3 to the upper stage of the building frame 2. In this way, the building frame 2 and the scaffolding plate 19 are sequentially assembled on the building frame 2, and moved to above the building frame 2 for sequentially assembling the handrails 3, and the reed 17 is always connected between the support columns 4. Assembling work can be performed in the state which was carried out.
[0023]
In dismantling the frame scaffold 1, conversely, the stopper 16 of the handrail 3 of the assembled uppermost building frame 2 is pushed to lower the support column 4 as shown in FIG. 1 and FIG. The building frame 2 can be dismantled sequentially, and also in this case, the recumbent rod 17 of the handrail 3 can always maintain the state of being connected between the support columns 4, so that the work can be performed safely. .
[0024]
In this manner, the frame scaffold 1 can be assembled and disassembled with the horizontal beam 17 always connected between the column parts 4 of the handrail 3, and the column part 4 can be reinforced by the adjacent horizontal beam 17 to It can also prevent wobble.
[0025]
Moreover, since the support | pillar part 4 is made into the shape of an elongate box frame and is clamped so that the leg pillar 8 of the building frame 2 may be held, there is no possibility that the handrail 3 will come off and it can maintain safely.
[0026]
【The invention's effect】
As described above, according to the present invention, the handrail support pillars are arranged to be movable up and down on the building pillars of the framework scaffolding for construction and the like, and the safety fence for the handrail is provided between these support pillars.

As a result, it is possible to safely assemble and disassemble the framework scaffold.
[0027]
In particular, a horizontal rail for the safety fence can be flexibly connected between the support columns via the link material, and the link member protrudes from the support column side to the side in response to the lifting and lowering of the support rail support column. The safety fence is formed by extending the link member that protrudes when the adjacent column part rises, so that the protruding side of the link member is dented to the original column part, and the horizontal rail of the handrail is always connected between the columns. When connecting the horizontal rail between the struts via the link material, the link on the side of the strut portion protrudes sideways and extends obliquely, and when the adjacent strut portion rises, the protruding link member is Indented into the original state, the recumbent can be installed horizontally between the struts, and as described above, it can be a safety fence in which the recumbent is always connected between the struts.
[0028]
In addition, the side rail for the safety rail of the handrail is flexibly linked and attached as two steps up and down between the columns, so that the side rail of the railing of the handrail is connected as above in two steps Can be maintained.
[0029]
Furthermore, the support rail part of the handrail is formed in an elongated box frame shape, and a sandwich sliding material is disposed in the elongated box frame-like column part to sandwich the leg of the building frame of the frame scaffold. By forming it as possible, it is possible to perform the work safely without detaching the support column of the handrail from the pedestal of the building frame.
[0030]
Furthermore, a stopper is provided on the support rail of the handrail so that the handrail can be locked at a predetermined position, the stopper is formed so as to be freely releasable when the handrail is raised and lowered, and when the stopper stops at the predetermined position, the stopper is a building frame of the frame scaffolding.
