Description

本発明は足場構造に係り、とくに足場板の長さ方向の両端にそれぞれ鳥居枠を立設し、しかも足場板の少なくとも一方の側面に沿うように両側の鳥居枠の支柱間に先行手摺りを取付けた足場構造に関する。   The present invention relates to a scaffold structure, and in particular, torii frames are erected at both ends in the length direction of the scaffold plate, and a leading handrail is provided between the columns of the torii frames on both sides so as to be along at least one side surface of the scaffold plate. It relates to the attached scaffold structure.

２階以上の高さの建造物を構築するときや、予め完成している建造物の外壁の塗装や補修工事等を行なうために、仮設足場を設けるようにしている。仮設足場は、フレームとなる鳥居枠を何段にも積重ねるとともに、鳥居枠を横方向に順次連結し、それぞれのユニットの中に足場板を取付けるようにしたものであって、とくに高所作業の作業性を改善し、安全性を確保するものである。   Temporary scaffolding is provided when building a building with a height of 2 floors or more, or for painting or repairing the outer wall of a previously completed building. The temporary scaffolding is a stack of torii frames that serve as frames, and the torii frames are sequentially connected in the horizontal direction so that scaffolding plates are installed in each unit. This will improve the workability and ensure safety.

このような足場構造において、とくに両側の鳥居枠の間に足場板を組込んだユニットの配列方向の終端において、鳥居枠の両側の支柱間の部分が開放されたままであると、転落事故を起す可能性がある。そこでこのような転落事故を防止するために、終端の鳥居枠の両側の支柱間に安全ガードを取付けるようにしている。また鳥居枠を何段にも組合せてユニットを上下に積重なるようにした足場構造において、とくに下段のユニットの外側面に先行手摺りを下から順次取付けるようにすると、次に取付けられる上段のユニットの外側面が下段の先行手摺りの上縁によって覆われているために、積重ね作業の安全性が向上する。   In such a scaffold structure, a fall accident may occur if the part between the supports on both sides of the torii frame remains open, especially at the end of the arrangement direction of the unit in which the scaffolding plate is incorporated between the torii frames on both sides. there is a possibility. Therefore, in order to prevent such a fall accident, safety guards are attached between the supports on both sides of the terminal torii frame. Also, in a scaffold structure in which the torii frames are combined in multiple steps and the units are stacked up and down, especially when the leading handrail is attached sequentially from the bottom to the outer surface of the lower unit, the upper unit to be installed next Since the outer side surface is covered with the upper edge of the lower handrail, the safety of the stacking work is improved.

ところが上記の鳥居枠の終端の支柱間の開放部分を閉じる安全ガードと、側面を覆う先行手摺りとが互いに直角に取付けられるようにした場合に、両者の干渉が起こって円滑に組立てができない可能性がある。   However, when the safety guard that closes the open part between the support pillars at the end of the torii frame and the preceding handrail that covers the side are attached at right angles to each other, they may interfere with each other and cannot be assembled smoothly. There is sex.

以下本願発明を図示の実施の形態によって説明する。図１は本実施の形態に係る足場構造に用いられる鳥居枠１０を示している。鳥居枠１０は、両側の一対の直立する支柱１１を備えるとともに、両側の支柱の両端部は横バー１２で連結されている。そして横バー１２と支柱１１とを両側の湾曲する補強材１３によって連結している。支柱１１は、上端側が一回り細い挿入軸１４から構成されている。何段にも積重ねたときに、下側の段の挿入軸１４が上側の段の鳥居枠１０の支柱１１の受入れ筒１５と嵌合され、これによって何段にも積重ねられるようになっている。   The present invention will be described below with reference to embodiments shown in the drawings. FIG. 1 shows a torii frame 10 used in the scaffold structure according to the present embodiment. The torii frame 10 includes a pair of upright support columns 11 on both sides, and both ends of the support columns on both sides are connected by horizontal bars 12. And the horizontal bar 12 and the support | pillar 11 are connected by the reinforcing material 13 which curves on both sides. The support | pillar 11 is comprised from the insertion axis | shaft 14 whose upper end side is a little thin. When many stages are stacked, the lower stage insertion shaft 14 is fitted to the receiving cylinder 15 of the support column 11 of the upper stage torii frame 10, thereby stacking many stages. .

次に足場ユニットの前面側の部分を覆う先行手摺り２０について図２により説明する。先行手摺り２０はその両端側が縦桟２１から構成され、縦桟２１と平行に、例えば２本の中桟２２が配設され、さらに両端の縦桟２１と中間の２本の中桟２２の上端とを横桟２３によって連結している。また縦桟２１の上端は斜めに屈曲されるとともに、両側の斜めに屈曲した縦桟２１の上端を連結するように上桟２４が固定される。また縦桟２１、中桟２２の下端を連結するように下桟25が取付けられる。   Next, the preceding handrail 20 that covers the front side portion of the scaffold unit will be described with reference to FIG. The leading handrail 20 is composed of vertical rails 21 at both ends, for example, two middle rails 22 are arranged in parallel with the vertical rails 21, and the vertical rails 21 at both ends and two intermediate rails 22 in the middle. The upper end is connected by a horizontal rail 23. The upper end of the vertical beam 21 is bent obliquely, and the upper beam 24 is fixed so as to connect the upper ends of the vertical beam 21 bent obliquely on both sides. A lower rail 25 is attached so as to connect the lower ends of the vertical rail 21 and the middle rail 22.

先行手摺り２０の両端にはそれぞれ押えレバー２６が取付けられるようになっている。押えレバー２６はとくに図１０および図１１に示すように、長さ方向に延びる長孔２７が形成して成り、この長孔２７に係合されるピン２８が先行手摺り２０の縦桟２１と連結されるようになっている。そして押えレバー２６が断面形状がＵ字状に構成されるとともに、基端側が切欠かれた切欠き２９を備え、この切欠き２９内に縦桟２１が挿通される。また押えレバー２６の底部であって切欠き２９と反対側の係合部３０は、鳥居枠１０の支柱１１を受入れて係合するようになっている。   A presser lever 26 is attached to each end of the preceding handrail 20. As shown in FIGS. 10 and 11, the presser lever 26 is formed with a long hole 27 extending in the length direction, and a pin 28 engaged with the long hole 27 is connected to the vertical rail 21 of the preceding handrail 20. It is designed to be connected. The presser lever 26 is configured to have a U-shaped cross section, and includes a notch 29 with a base end notched, and the vertical beam 21 is inserted into the notch 29. Further, the engaging portion 30 on the bottom side of the presser lever 26 and opposite to the notch 29 is adapted to receive and engage the column 11 of the torii frame 10.

次に終端の鳥居枠１０の支柱間に取付けられる安全ガード３３について図３〜図６により説明する。安全ガード３３は、横方向に延びる取付けバー３４を備えるとともに、この取付けバー３４の下側には、Ｕ字状バー３５が取付けられるようになっている。取付けバー３４およびＵ字状バー３５は、何れも鋼パイプから構成され、両端が押し潰されて扁平になっている。そしてＵ字状バー３５の両側の上端部が溶接位置３６において、取付けバー３４の下面に溶着されている。そして取付けバー３４はその両端の部分がクランパ３７を介して鳥居枠１０の支柱１１に結合されるようになっている。クランパ３７を取付けバー３４の両端に取付けるために、中空リベット３８が用いられ、図６に示すように取付けバー３４の両端の取付け孔３９の部分に中空リベット３８を介してクランパ３７が取付けられている。またＵ字状バー３５にはその外側部にそれぞれ横方向に突出するように当接片４０が溶接して取付けられている。   Next, the safety guard 33 attached between the supports of the terminal torii frame 10 will be described with reference to FIGS. The safety guard 33 includes a mounting bar 34 extending in the lateral direction, and a U-shaped bar 35 is attached to the lower side of the mounting bar 34. Both the attachment bar 34 and the U-shaped bar 35 are made of steel pipes, and both ends are crushed and flattened. The upper ends of both sides of the U-shaped bar 35 are welded to the lower surface of the mounting bar 34 at the welding position 36. The mounting bar 34 is coupled to the support column 11 of the torii frame 10 through clampers 37 at both ends. In order to attach the clamper 37 to both ends of the mounting bar 34, hollow rivets 38 are used. As shown in FIG. 6, the clamper 37 is attached to the portions of the mounting holes 39 on both ends of the mounting bar 34 via the hollow rivets 38. Yes. Abutting pieces 40 are welded to the U-shaped bar 35 so as to protrude laterally from the outer side of the U-shaped bar 35, respectively.

図７はこのような安全ガード３３を鳥居枠１０の支柱１１間に取付け固定した構成を示している。ここで安全ガード３３のＵ字状バー３５の両側の垂直部分は、鳥居枠１０の両側の支柱１１に対して、後述する足場板の幅方向に対して内側に偏倚するようになっており、このために先行手摺り２０の押えレバー２６が安全ガード３３のＵ字状バー３５と干渉することが防止されるようになっている。なお安全ガード３３の当接片４０と先行手摺り２０の押えレバー２６との干渉の防止は、両者を互いに高さ方向において上下にずらすことにより行なわれる。   FIG. 7 shows a configuration in which such a safety guard 33 is attached and fixed between the columns 11 of the torii frame 10. Here, the vertical portions on both sides of the U-shaped bar 35 of the safety guard 33 are biased inward with respect to the pillar 11 on both sides of the torii frame 10 with respect to the width direction of the scaffolding plate described later, For this reason, the presser lever 26 of the preceding handrail 20 is prevented from interfering with the U-shaped bar 35 of the safety guard 33. The interference between the contact piece 40 of the safety guard 33 and the presser lever 26 of the preceding handrail 20 is prevented by shifting both of them up and down in the height direction.

図８は両側の鳥居枠１０と、前面側の先行手摺り２０と、背面側の斜め桟４５とによって組立てられた足場構造のユニットを示している。鳥居枠１０を互いに足場板４６の長さ方向に所定の間隔をおいて配設するとともに、背面側の部分を互いに斜めに交差する２本の斜め桟４５によって連結する。なお連結する部位には、予め係止手段が設けられている。また一対の鳥居枠１０の間であって前面側の部分には先行手摺り２０が取付けられる。先行手摺り２０は、その両端にそれぞれ取付けられている押えレバー２６を鳥居枠１０の支柱１１の部分に係合させることによって、上端のばらつきが防止される構造になっている。   FIG. 8 shows a unit of the scaffold structure assembled by the torii frames 10 on both sides, the front handrail 20 on the front side, and the diagonal beam 45 on the back side. The torii frames 10 are arranged with a predetermined interval in the length direction of the scaffolding plate 46, and the back side portions are connected by two oblique bars 45 that obliquely intersect each other. In addition, the latching means is previously provided in the site | part to connect. A leading handrail 20 is attached between the pair of torii frames 10 and on the front side. The leading handrail 20 has a structure in which variations in the upper end are prevented by engaging the presser levers 26 respectively attached to both ends thereof with the column 11 of the torii frame 10.

ここで先行手摺り２０は、下段側の足場ユニットを組立てると、上半分が上段の前面側を覆うようになる。すなわち組立てられる前の段階ですでに先行手摺り２０の上側の部分の約１ｍの高さまで上桟２４が足場板４６よりも上方に延びてきており、これによって前面が開放された状態の発現を防止する。これにより、開放された前面から転落するのが防止され、何段にも順次組み立てていく場合の安全性が著しく高まるようにしたものである。なお各ユニットの足場の底部を覆うように足場板４６が取付けられる。また図８の構造は、前面側が先行手摺り２０から構成され、背面側が斜め桟４５をクロスさせて配置した構成になっているが、背面側についても先行手摺り２０を取付けるようにしてもよい。一般に建物の外壁に近接して足場を構築する場合には、図８のような形態の組み立てが多くなる。   Here, when the lower hand side scaffolding unit 20 is assembled, the upper hand half of the leading handrail 20 covers the upper front side. That is, in the stage before the assembly, the upper rail 24 has already extended above the scaffolding plate 46 to a height of about 1 m in the upper part of the leading handrail 20 so that the front surface is opened. To prevent. As a result, it is possible to prevent falling from the opened front face, and to significantly increase the safety when assembling in order. A scaffold plate 46 is attached so as to cover the bottom of the scaffold of each unit. Further, in the structure of FIG. 8, the front side is composed of the leading handrail 20 and the rear side is arranged by crossing the oblique rails 45, but the leading handrail 20 may be attached to the back side as well. . In general, when a scaffold is constructed in the vicinity of the outer wall of a building, assembly in the form as shown in FIG. 8 increases.

次に図９〜図１１は、このようにして前面側に先行手摺り２０が装着され、終端の鳥居枠１０の支柱１１間に安全ガード３３が取付けられたときの先行手摺り２０の押えレバー２６と安全ガード３３の当接片４０との干渉の防止の構造を示している。先行手摺り２０の押えレバー２６はピン２８によって縦桟２１に回動可能に取付けられ、この押えレバー２６を水平に倒すと、押えレバー２６の先端側の係合部３０が鳥居枠１０の支柱１１の側面に係合され、これによって先行手摺り２０の上端側の部分のばたつきが支柱１１によって防止されるようになる。しかも安全ガード３３は、そのＵ字状バー３５の垂直部分の足場板４６の幅方向の寸法が上記鳥居枠１０の支柱１１間の寸法よりも短くなっており、Ｕ字状バー３５の垂直部分が足場板４６の幅方向内側に偏倚している。従って押えレバー４６が安全ガード３３のＵ字状バー３５の垂直部分と干渉されることがない。しかも押えレバー２６と安全ガード３３のＵ字状バー３５の両端に外方に突出するように設けられている当接片４０とは、互いに高さ方向の異なる位置に取付けられており、両者が互いに干渉することがない。図１１はとくに当接片４０が押えレバー２６に対して上方位置にあるときの関係を示している。   Next, in FIGS. 9 to 11, when the leading handrail 20 is mounted on the front side in this way, and the safety guard 33 is attached between the columns 11 of the terminal torii frame 10, the holding lever of the leading handrail 20 is shown. 26 shows a structure for preventing interference between the contact guard 26 and the contact piece 40 of the safety guard 33. The presser lever 26 of the leading handrail 20 is pivotally attached to the vertical beam 21 by a pin 28. When the presser lever 26 is tilted horizontally, the engaging portion 30 on the front end side of the presser lever 26 becomes the support column of the torii frame 10. 11 is engaged with the side surface of the front rail 11, and fluttering of the upper end side portion of the handrail 20 is prevented by the column 11. In addition, the safety guard 33 has a vertical dimension of the U-shaped bar 35 in the width direction of the scaffolding plate 46 shorter than the dimension between the supports 11 of the torii frame 10, and the vertical part of the U-shaped bar 35. Is biased inward in the width direction of the scaffold plate 46. Therefore, the presser lever 46 is not interfered with the vertical portion of the U-shaped bar 35 of the safety guard 33. Moreover, the presser lever 26 and the abutment piece 40 provided so as to protrude outwardly at both ends of the U-shaped bar 35 of the safety guard 33 are attached to different positions in the height direction. They do not interfere with each other. FIG. 11 particularly shows the relationship when the contact piece 40 is in the upper position with respect to the presser lever 26.

以上のような構成に係る足場構造は、横方向に連結される鳥居枠１０間の前面側の開口部が先行手摺り２０によって閉じられるとともに、終端の鳥居枠１０の両側の支柱１１間の部分が安全ガード３３によって閉じられる。従って安全性が高い構造になる。しかもこれらの先行手摺り２０および安全ガード３３は、何れも作業性を損なうことがない。また先行手摺り２０の押えレバー２６と安全ガード３３の当接片４０との干渉がないために、組立てに支障を生ずることがない。また足場ユニットを何段にも積重ねる際に、下段側のユニットの先行手摺り２０が上段の前面の足場板４６の上面から約１ｍの高さまで延びるようになっているために、前面側の部分の開放が回避され、さらに安全性が高まる。   In the scaffold structure according to the above configuration, the opening on the front side between the torii frames 10 connected in the lateral direction is closed by the leading handrail 20 and the portion between the columns 11 on both sides of the terminal torii frame 10 Is closed by the safety guard 33. Therefore, the structure is highly safe. In addition, neither the handrail 20 nor the safety guard 33 impairs workability. Further, since there is no interference between the presser lever 26 of the preceding handrail 20 and the contact piece 40 of the safety guard 33, there is no problem in assembling. Further, when stacking the scaffold units in many stages, the leading handrail 20 of the lower unit extends from the upper surface of the upper front scaffolding plate 46 to a height of about 1 m. Opening of the part is avoided, and safety is further increased.

また安全ガード３３は、上述の如くＵ字状バー３５の縦方向に延びる垂直部分が内側に偏倚しており、先行手摺り２０の押さえレバー２６と干渉しないようになっている。しかも取付けバー３４とＵ字状バー３５とによって、閉じた枠体を構成しているために、持運んだり吊るし上げたりするときの安全性が高くなる。しかも取付けバー３４の両端が中空リベット３８によってクランパ３７と結合されるようになっているために、軽量化が図られ、ボルトから成る突出部が無くなり、しかも中空リベット３８の内側の孔を係止手段として利用することが可能になる。   As described above, the vertical portion of the safety bar 33 extending in the vertical direction of the U-shaped bar 35 is biased inward so as not to interfere with the pressing lever 26 of the preceding handrail 20. Moreover, since the mounting bar 34 and the U-shaped bar 35 form a closed frame body, the safety when carrying or lifting is increased. Moreover, since both ends of the mounting bar 34 are connected to the clamper 37 by the hollow rivets 38, the weight is reduced, the projecting parts made of bolts are eliminated, and the holes inside the hollow rivets 38 are locked. It can be used as a means.

以上本願発明を図示の一実施の形態によって説明したが、本願発明は上記実施の形態によって限定されることなく、本願発明の技術的思想の範囲内において各種の変更が可能である。例えば上記実施の形態における足場ユニットの裏側の部分についても、斜め桟４５に代えて先行手摺り２０を取付ける構造を採用してもよい。また先行手摺り２０や押えレバー２６の具体的な構造についても、各種の設計変更や寸法の変更が可能である。   While the present invention has been described with reference to the illustrated embodiment, the present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the technical idea of the present invention. For example, a structure in which the handrail 20 is attached to the back portion of the scaffold unit in the above embodiment instead of the oblique beam 45 may be employed. Various design changes and dimension changes can be made to the specific structures of the handrail 20 and the presser lever 26.

本願発明は、建築工事等の高所作業における安全性の向上と作業性の改善のための足場構造として広く利用することが可能である。   The present invention can be widely used as a scaffold structure for improving safety and improving workability in high-place work such as construction work.
