Description

この発明は、例えば2階建てや3階建て等の低中層の戸建住宅用足場に関するものである。   The present invention relates to a scaffold for a low-mid-rise detached house such as a two-story building or a three-story building.

一般に、戸建住宅を建設する場合、地上に適宜間隔をおいて立設される複数の支柱と、各支柱に装着されるブラケット間に架設される足場板と、手摺とを具備する足場を組み立てて外装作業や屋根作業等を行っている。この場合、金属板を断面略コ字状に曲折した楔受け部材を溶接等によって支柱に固着して、ブラケットあるいは手摺の端部に装着された楔体をハンマで叩いてブラケットや手摺等を固定する楔式足場が知られている(例えば、特許文献1参照)。
特開平5−222839号公報(特許請求の範囲、段落番号0009〜0012、図2)
In general, when constructing a detached house, assemble a scaffolding that includes a plurality of columns that are erected on the ground at appropriate intervals, a scaffolding plate that is installed between brackets that are attached to each column, and a handrail. We are doing exterior work and roof work. In this case, a wedge receiving member obtained by bending a metal plate into a substantially U-shaped cross section is fixed to the support by welding or the like, and the bracket or the handrail attached to the end of the handrail is hit with a hammer to fix the bracket or the handrail. A wedge-type scaffold is known (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 5-2222839 (Claims, paragraph numbers 0009 to 0012, FIG. 2)

ところで、この種の足場においては、作業効率を高めるために支柱に取り付けられる手摺やブラケットを直交状に交差して取り付ける場合があり、そのため、4個の楔受け部材を上下方向に近接してクロス状に配設して溶接等で固着している。   By the way, in this kind of scaffolding, there are cases where handrails and brackets attached to the support pillars are attached so as to intersect at right angles in order to increase work efficiency. Therefore, the four wedge receiving members are crossed close to each other in the vertical direction. It is arranged in a shape and fixed by welding or the like.

しかしながら、従来の楔受け部材においては、脚部先端部の溶接部において溶け込みが少ないため、溶接強度が弱くなるので、ビードの余盛りを大きくしなければならない。しかし、ビードの余盛りを大きくすると、楔受け部材に楔体を挿入したとき、上段の楔受け部材に楔体を挿入した場合には、楔体が近傍下側の直交する楔受け部材の溶接部に当り、また、下段の楔受け部材に楔体を挿入した場合には、近傍上側の楔受け部材の溶接部に楔体が当ってしまい、手摺やブラケットの取付及び解体の作業性が悪いばかりか、楔体が溶接部に当たったまま楔体を挿入すると、溶接部に亀裂等が生じて楔受け部材が支柱から浮き上がることがある。このように楔受け部材が支柱から浮き上がると、手摺やブラケットの他端側の楔体の挿入に支障をきたし、手摺やブラケットの取付状態が不安定になるという問題があった。   However, in the conventional wedge receiving member, since there is little penetration in the welded portion at the tip of the leg portion, the welding strength is weakened, so the extra bead must be increased. However, if the surplus of the bead is increased, when the wedge body is inserted into the wedge receiving member, when the wedge body is inserted into the upper wedge receiving member, the wedge body is welded to the orthogonal wedge receiving member on the lower side in the vicinity. When the wedge body is inserted into the lower wedge receiving member, the wedge body hits the welded portion of the upper wedge receiving member, and the workability of attaching and dismantling the handrail and bracket is poor. In addition, if the wedge body is inserted while the wedge body is in contact with the welded portion, a crack or the like may occur in the welded portion, and the wedge receiving member may float from the support column. When the wedge receiving member is lifted from the column in this way, there is a problem that the insertion of the wedge body at the other end of the handrail or the bracket is hindered, and the attachment state of the handrail or the bracket becomes unstable.

この発明は上記事情に鑑みてなされたもので、構成部材に軽量かつ強度性を持たせて組立及び解体の作業性の向上と安全性の向上を図れるようにした戸建住宅用足場の取付構造を提供することを目的とする。   The present invention has been made in view of the above circumstances, and has a structure for mounting a scaffold for a detached house, which can improve the workability and safety of assembling and dismantling by giving the components light weight and strength. The purpose is to provide.

上記課題を解決するために、請求項1記載の発明は、地上に適宜間隔をおいて立設される複数の支柱と、各支柱に固着された楔受け部材に楔着される楔体を有するブラケットと、このブラケット間に着脱可能に架設される足場板と、上記楔受け部材に楔着される楔体を有する手摺とを具備する戸建住宅用足場の取付構造であって、 上記楔受け部材が、断面略コ字状であって、その脚部の先端部の外側に薄肉段差部を設けた形状に押出成形された形材を、所定長さに切断してなり、 上記楔受け部材の脚部先端部を上記支柱の外周面に当接した状態で、上記薄肉段差部と支柱外周面とを溶接により固着してなる、ことを特徴とする。   In order to solve the above-mentioned problem, the invention according to claim 1 has a plurality of support columns standing on the ground at appropriate intervals, and a wedge body wedged by a wedge receiving member fixed to each support column. A structure for mounting a scaffold for a detached house comprising a bracket, a scaffold plate detachably mounted between the brackets, and a handrail having a wedge body wedged on the wedge receiving member, The member has a substantially U-shaped cross section, and is cut into a predetermined length from a shape that has been extruded into a shape in which a thin stepped portion is provided outside the tip of the leg, and the wedge receiving member The thin stepped portion and the support outer peripheral surface are fixed by welding in a state in which the leg tip end portion is in contact with the outer peripheral surface of the support post.

この発明において、上記楔受け部材における薄肉段差部が、上部から下部に渡って漸次小さくなるような勾配を有するように切断されている方が好ましい(請求項2)。   In the present invention, it is preferable that the thin stepped portion of the wedge receiving member is cut so as to have a gradient that gradually decreases from the upper part to the lower part (Claim 2).

また、上記楔受け部材の薄肉段差部の段部を傾斜状に形成する方が好ましい(請求項3)。   Further, it is preferable that the step portion of the thin step portion of the wedge receiving member is formed in an inclined shape (claim 3).

加えて、上記支柱の外周面に、楔受け部材の取付段部溝を沿設し、この取付段部溝に、上記楔受け部材の脚部を係合させるようにする方が好ましい(請求項4)。   In addition, it is preferable that the mounting step portion groove of the wedge receiving member is provided along the outer peripheral surface of the support column, and the leg portion of the wedge receiving member is engaged with the mounting step portion groove. 4).

この発明によれば、上記のように構成されているので、以下のような効果が得られる。   According to this invention, since it is configured as described above, the following effects can be obtained.

(1)請求項1記載の発明によれば、楔受け部材が、断面略コ字状であって、脚部の先端部の外側に薄肉段差部を設けた形状に押出成形された形材を、所定長さに切断してなるので、金属板を折曲してなる楔受け部材に比べて軽量な楔受け部材を容易に作製することができる。また、楔受け部材の脚部先端部を支柱の外周面に当接した状態で、薄肉段差部と支柱外周面とを溶接により固着することにより、ビードの余盛りを大きくすることなく、楔受け部材を支柱に強固に固着することができる。更に、楔体の打ち込みの際に溶接部に当たる心配がない。したがって、足場の組立及び解体の作業性の向上と安全性の向上を図ることができる。   (1) According to the first aspect of the present invention, the wedge receiving member has a substantially U-shaped cross section and is extruded into a shape in which a thin step portion is provided outside the tip end portion of the leg portion. Since it is cut to a predetermined length, a lightweight wedge receiving member can be easily produced as compared with a wedge receiving member formed by bending a metal plate. In addition, the wedge receiving member can be secured without increasing the extra bead by fixing the thin stepped portion and the outer peripheral surface of the support by welding in a state in which the leg tip of the wedge receiving member is in contact with the outer peripheral surface of the support. The member can be firmly fixed to the column. Furthermore, there is no worry of hitting the welded portion when the wedge body is driven. Therefore, it is possible to improve the workability and safety of assembling and dismantling the scaffold.

(2)請求項2記載の発明によれば、楔受け部材における薄肉段差部を、上部から下部に渡って漸次小さくなるような勾配を有するように切断することにより、上端が拡開し、下端が狭小する勾配をもたせて楔受け部材を支柱に容易に固着することができる。したがって、上記(1)に加えて更に楔受け部材と楔体との係合を強固にすることができる。   (2) According to the invention described in claim 2, the upper end is expanded and the lower end is cut by cutting the thin stepped portion of the wedge receiving member so as to have a gradient that gradually decreases from the upper part to the lower part. It is possible to easily fix the wedge receiving member to the support column with a narrowing gradient. Therefore, in addition to the above (1), the engagement between the wedge receiving member and the wedge body can be further strengthened.

(3)請求項3記載の発明によれば、楔受け部材の薄肉段差部の段部を傾斜状に形成することにより、溶接部のビードの接触面積を大きくすることができると共に、ビードの余盛りを容易にすることができる。したがって、上記(1),(2)に加えて更に楔受け部材の固着を強固にすることができると共に、安全性の向上を図ることができる。   (3) According to the invention described in claim 3, by forming the stepped portion of the thin stepped portion of the wedge receiving member in an inclined shape, the contact area of the bead of the welded portion can be increased, and the remaining bead is increased. The serving can be facilitated. Therefore, in addition to the above (1) and (2), the wedge receiving member can be further firmly fixed, and safety can be improved.

(4)請求項4記載の発明によれば、支柱の外周面に、楔受け部材の取付段部溝を沿設し、この取付段部溝に、楔受け部材の脚部を係合させるようにすることにより、楔受け部材を固着する際の位置決めを容易にすることができると共に、楔受け部材の支柱への固着を確実にすることができる。したがって、上記(1)〜(3)に加えて更に楔受け部材の固着を強固にすることができると共に、安全性の向上を図ることができる。   (4) According to the invention described in claim 4, the mounting step portion groove of the wedge receiving member is provided along the outer peripheral surface of the support column, and the leg portion of the wedge receiving member is engaged with the mounting step portion groove. By doing so, positioning at the time of fixing the wedge receiving member can be facilitated, and fixing of the wedge receiving member to the support column can be ensured. Accordingly, in addition to the above (1) to (3), the wedge receiving member can be further firmly fixed, and safety can be improved.

以下に、この発明の最良の実施形態を添付図面に基づいて詳細に説明する。   DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the best embodiment of the present invention will be described in detail with reference to the accompanying drawings.

図1は、この発明の戸建住宅用足場の要部を示す斜視図、図2は、図1のI部の拡大断面図、図3は、図2のII−II線に沿う断面図、図4は、図1のI部の拡大斜視図である。   1 is a perspective view showing a main part of a scaffold for a detached house according to the present invention, FIG. 2 is an enlarged sectional view of a portion I in FIG. 1, and FIG. 3 is a sectional view taken along line II-II in FIG. FIG. 4 is an enlarged perspective view of a portion I in FIG.

上記足場は、地上に適宜間隔をおいて立設される複数の支柱1と、各支柱1に固着された楔受け部材2に楔着される楔体3を有するブラケット20と、このブラケット20間に着脱可能に架設される足場板40と、各支柱1の楔受け部材2に楔着される楔体3を有する手摺30とで主に構成されている。   The scaffold includes a plurality of struts 1 standing on the ground at appropriate intervals, a bracket 20 having a wedge body 3 wedged on a wedge receiving member 2 fixed to each strut 1, and a space between the brackets 20. It is mainly comprised by the scaffolding board 40 constructed so that attachment or detachment is possible, and the handrail 30 which has the wedge body 3 wedged by the wedge receiving member 2 of each support | pillar 1.

上記支柱1は、弾性変形可能なロックピン50を介して着脱可能に嵌挿固定される、外径寸法が略同一の複数の支柱体10にて構成されており、少なくとも一つの支柱体10はアルミニウムパイプにて形成されている。この場合、例えば、地上に設置されるジャッキベース部材4に連結される最下段の支柱体10Aを鉄製のパイプ部材にて形成し、支柱体10A以外の支柱体10を全てアルミニウムパイプ製にするか、あるいは、鉄製パイプとアルミニウムパイプの混合とすることができる。なお、ジャッキベース部材4に連結される最下段の支柱体を含めて全てアルミニウムパイプ製の支柱体10とすることも可能である。   The support column 1 is composed of a plurality of support columns 10 which are detachably fitted and fixed via elastically deformable lock pins 50, and have substantially the same outer diameter. It is made of aluminum pipe. In this case, for example, is the bottom column 10A connected to the jack base member 4 installed on the ground formed of an iron pipe member and all columns 10 other than the column 10A are made of aluminum pipes? Alternatively, a mixture of an iron pipe and an aluminum pipe can be used. In addition, it is also possible to make all the support bodies 10 made of aluminum pipes including the lowermost support body connected to the jack base member 4.

アルミニウムパイプ製支柱体10(以下に、支柱体10という)は、上端に小径部11を延在し、下端部には下段に位置する支柱体10(10A)の上端小径部11を嵌挿し得る拡管部12を有し、拡管部12の対向する側面にロックピン50の係合孔14を有し、かつ、この支柱体10の外周面の対向する4箇所に、楔受け部材2を取り付けるための断面略直角状の取付段部溝15が支柱体10の長手方向に沿設されている(図3及び図4参照)。また、支柱体10における適宜間隔をおいた取付段部溝15には、断面略コ字状に形成される楔受け部材2の脚部である脚片2aが係合されると共に、その接合部が溶接Wによって固着されている(図3参照)。したがって、楔受け部材2の脚片2aが取付段部溝15の底面と側面に接触するので、溶接部の接触面積が広くなり、楔受け部材2が強固に固着される。   The aluminum pipe support 10 (hereinafter referred to as the support 10) has a small diameter portion 11 extending at the upper end, and the upper end small diameter portion 11 of the support 10 (10A) positioned at the lower stage can be inserted into the lower end. In order to attach the wedge receiving member 2 to the four opposing locations on the outer peripheral surface of the column body 10, having the expanded tube portion 12, the engaging hole 14 of the lock pin 50 on the opposing side surface of the expanded tube portion 12. The mounting step groove 15 having a substantially right-angle cross section is provided along the longitudinal direction of the column 10 (see FIGS. 3 and 4). In addition, a leg piece 2a, which is a leg portion of the wedge receiving member 2 formed in a substantially U-shaped cross section, is engaged with the mounting step portion groove 15 at an appropriate interval in the column body 10, and its joint portion. Is fixed by welding W (see FIG. 3). Therefore, the leg pieces 2a of the wedge receiving member 2 come into contact with the bottom and side surfaces of the attachment step groove 15, so that the contact area of the welded portion is widened, and the wedge receiving member 2 is firmly fixed.

なお、この場合、4個の楔受け部材2が近傍部位に固着されており、対向する2個の楔受け部材2が同一高さ位置に固着され、残りの2個の楔受け部材2が上段の楔受け部材2の近傍下方側の直交する対向位置に固着されている(図2ないし図4参照)。   In this case, the four wedge receiving members 2 are fixed in the vicinity, the two opposing wedge receiving members 2 are fixed at the same height position, and the remaining two wedge receiving members 2 are in the upper stage. The wedge receiving member 2 is fixed to the opposite position on the lower side in the vicinity (see FIGS. 2 to 4).

この場合、楔受け部材2は、図5に示すように、断面略コ字状であって、両脚部である脚片2aの先端部の外側に薄肉段差部2bを設けた形状に押出成形されたアルミニウム合金製の形材を、所定長さに切断したものにて形成されている。また、楔受け部材2における薄肉段差部2bは、上部から下部に渡って漸次小さくなるような勾配2cを有するように切断されており、楔受け部材2の薄肉段差部2bの段部2dに傾斜面2eが形成されている(図5(b)参照)。   In this case, as shown in FIG. 5, the wedge receiving member 2 has an approximately U-shaped cross section and is extruded into a shape in which a thin stepped portion 2b is provided on the outer side of the distal end portion of the leg piece 2a that is both legs. It is formed by cutting a shape made of aluminum alloy into a predetermined length. Further, the thin step 2b in the wedge receiving member 2 is cut so as to have a gradient 2c that gradually decreases from the upper part to the lower part, and is inclined to the step 2d of the thin step 2b of the wedge receiving member 2. A surface 2e is formed (see FIG. 5B).

このように、楔受け部材2の脚片2aの先端部に設けられる薄肉段差部2bに上部から下部に渡って漸次小さくなるような勾配2cを設けることにより、上端が拡開し、下端が狭小する勾配をもたせて楔受け部材2を支柱体10に容易に固着することができるので、楔受け部材2と楔体3との係合を強固にすることができる。   Thus, by providing the thin step 2b provided at the tip of the leg piece 2a of the wedge receiving member 2 with the gradient 2c that gradually decreases from the upper part to the lower part, the upper end is expanded and the lower end is narrow. Since the wedge receiving member 2 can be easily fixed to the support column 10 with a gradient, the engagement between the wedge receiving member 2 and the wedge body 3 can be strengthened.

また、楔受け部材2の薄肉段差部2bの段部2dに傾斜面2eを形成することにより、溶接W部のビードの接触面積を大きくすることができると共に、ビードの余盛りを容易にすることができるので、楔受け部材2の固着を強固にすることができると共に、安全性の向上を図ることができる。   Further, by forming the inclined surface 2e on the stepped portion 2d of the thin stepped portion 2b of the wedge receiving member 2, it is possible to increase the contact area of the bead of the welded W portion and to facilitate the overfilling of the bead. Therefore, the wedge receiving member 2 can be firmly fixed and safety can be improved.

また、支柱体10は、押出成形によって取付段部溝15を同時に形成したアルミニウムパイプにて形成される支柱体基部10aの上端開口部に、アルミニウムパイプにて形成される小径部11を挿入し、支柱体基部10aの上端部の側面に設けられた貫通孔10bを溶接Wして支柱体基部10aと小径部11とを固定している。なお、支柱体基部10aの下端部を拡管加工して拡管部12を形成する。このように形成される支柱体10は、異なる長さの数種類、例えば3m80cm、1m90cm、95cmの3種類が用意されて、目的に応じて組み合せできるようになっている。なお、支柱体10,10Aの外径寸法は、略同一寸法であれば任意の寸法であってもよい。   Further, the column body 10 has a small diameter portion 11 formed of an aluminum pipe inserted into an upper end opening of a column body base portion 10a formed of an aluminum pipe in which the mounting step groove 15 is simultaneously formed by extrusion molding. The through-hole 10b provided in the side surface of the upper end part of the support | pillar base 10a is welded W, and the support | pillar base 10a and the small diameter part 11 are fixed. In addition, the expanded pipe part 12 is formed by expanding the lower end of the column base 10a. The pillar body 10 formed in this way is prepared in several types with different lengths, for example, 3 m80 cm, 1 m90 cm, and 95 cm, and can be combined according to the purpose. In addition, the outer diameter dimensions of the support bodies 10 and 10A may be arbitrary dimensions as long as they are substantially the same dimensions.

上記のように、支柱体10と鉄製支柱体10Aの外径寸法、小径部11の外径寸法を同一にすると共に、拡管部12の内径寸法と鉄製支柱体10Aの内径寸法とを同一にすることにより、支柱体10と鉄製支柱体10Aとに互換性を持たせて選択使用することができる。すなわち、支柱体10の拡管部12に鉄製支柱体10Aの小径部11Aを嵌挿したり、あるいは、鉄製支柱体10Aの下端部に支柱体10の小径部11を嵌挿して、支柱体10と鉄製支柱体10Aとを適宜選択して使用することができる。したがって、既存の鉄製支柱体10Aと支柱体10とを同様に取り扱うことができるので、在庫管理や運搬が便利となる。   As described above, the outer diameter size of the support column 10 and the iron support body 10A and the outer diameter size of the small diameter portion 11 are made the same, and the inner diameter size of the tube expansion portion 12 and the inner diameter size of the iron support body 10A are made the same. Thus, it is possible to select and use the column body 10 and the iron column body 10A with compatibility. That is, the small-diameter portion 11A of the iron strut body 10A is inserted into the expanded portion 12 of the strut body 10, or the small-diameter portion 11 of the strut body 10 is inserted into the lower end portion of the iron strut body 10A, The support 10A can be appropriately selected and used. Therefore, since the existing iron support 10A and the support 10 can be handled in the same manner, inventory management and transportation are convenient.

上記手摺30は、図6及び図7に示すように、上下部に肉厚部32が形成されると共に、対向する両外側面に、端部側に開口して軸方向に延びる凹状取付部33が形成されたアルミニウムパイプ製の手摺本体31と、この手摺本体31の端部に装着されるアルミダイキャスト製の楔体3とを具備している。   As shown in FIGS. 6 and 7, the handrail 30 has thick portions 32 formed at the upper and lower portions thereof, and concave mounting portions 33 that open to the end portions and extend in the axial direction on opposite outer side surfaces. A handrail main body 31 made of an aluminum pipe formed with an aluminum pipe, and a wedge body 3 made of aluminum die cast attached to an end portion of the handrail main body 31.

この場合、楔体3は、図8ないし図10に示すように、手摺本体31の凹状取付部33に嵌合する凹状部34を有する取付筒部35と、この取付筒部35に例えば溶接等によって固着、あるいは一体に形成される楔部36とで形成されている。なお、楔体3の先端側の支柱当接面3aには、支柱体10の外周面と相似形状の凹状面3bが形成されている(図8参照)。このように、楔体3の先端側の支柱当接面3aに、支柱体10の外周面と相似形状の凹状面3bを形成することにより、楔体3を楔受け部材2に打ち込んだ状態において凹状面3bが支柱体10の外周面に密接して、ガタツキを防止することができる。   In this case, as shown in FIGS. 8 to 10, the wedge body 3 includes an attachment cylinder portion 35 having a concave portion 34 that fits into the concave attachment portion 33 of the handrail main body 31, and, for example, welding to the attachment cylinder portion 35. And a wedge portion 36 that is fixed or integrally formed. Note that a concave surface 3b having a similar shape to the outer peripheral surface of the column body 10 is formed on the column contact surface 3a on the distal end side of the wedge body 3 (see FIG. 8). In this manner, in the state in which the wedge body 3 is driven into the wedge receiving member 2 by forming the concave surface 3b similar to the outer peripheral surface of the column body 10 on the column contact surface 3a on the distal end side of the wedge body 3. The concave surface 3b is in close contact with the outer peripheral surface of the column body 10, and rattling can be prevented.

上記のように形成される楔体3を手摺本体31に装着するには、図9に示すように、取付筒部35及び手摺本体31の凹状取付部33に穿設された貫通孔37を貫通するボルト38にナット39を締結して手摺本体31に楔体3を固着する。この際、ボルト38の頭部38a及びナット39を凹状部34内に納めて、外部への突出部をできる限り少なくしてある。したがって、作業者が不用意に手摺30に手や衣服を引っ掛けるのを防止することができる。   In order to attach the wedge body 3 formed as described above to the handrail main body 31, as shown in FIG. 9, it penetrates through the through-hole 37 formed in the attachment cylindrical portion 35 and the concave attachment portion 33 of the handrail main body 31. The nut 39 is fastened to the bolt 38 to be fixed, and the wedge body 3 is fixed to the handrail main body 31. At this time, the head portion 38a and the nut 39 of the bolt 38 are accommodated in the concave portion 34, and the protruding portion to the outside is reduced as much as possible. Therefore, it is possible to prevent an operator from inadvertently hooking a hand or clothes on the handrail 30.

上記ブラケット20は、図11に示すように、上下部に肉厚部22が形成されるアルミニウムパイプ製のブラケット本体21と、このブラケット本体21の両端部に装着されるアルミダイキャスト製の楔体3Aと、先端がブラケット本体21の下面に溶接等によって固着され、基端部に支柱体10(10A)の側面に当接するV字状当接部23を有するアルミニウム板製のブレース24と、このブレース24の基端側とブラケット本体21の下面とにそれぞれ溶接等によって固着されるアルミニウム製の補強板25と、ブラケット本体21の対向する4箇所にそれぞれ溶接等によって固着される4個の断面略コ字状の楔受け部材2Aとを具備している。なお、ブラケット本体21の両側の2箇所の対向する部位には、断面略コ字状の楔受け部材2Aが溶接等により固着されている。   As shown in FIG. 11, the bracket 20 includes a bracket body 21 made of aluminum pipe having thick portions 22 formed at the upper and lower portions thereof, and a wedge body made of aluminum die cast that is attached to both ends of the bracket body 21. 3A, an aluminum plate brace 24 having a distal end fixed to the lower surface of the bracket body 21 by welding or the like and having a V-shaped contact portion 23 that contacts the side surface of the column 10 (10A) at the proximal end portion, An aluminum reinforcing plate 25 fixed to the base end side of the brace 24 and the lower surface of the bracket main body 21 by welding or the like, and four cross sections substantially fixed to four opposing positions of the bracket main body 21 by welding or the like, respectively. And a U-shaped wedge receiving member 2A. Note that a wedge receiving member 2A having a substantially U-shaped cross section is fixed to two opposing portions on both sides of the bracket body 21 by welding or the like.

この場合、楔体3Aは、ブラケット本体21に嵌合される取付筒部35と、この取付筒部35に例えば溶接等によって固着、あるいは一体に形成される楔部36とで形成されている。この楔体3Aをブラケット本体21に装着するには、取付筒部35及びブラケット本体21に穿設された貫通孔(図示せず)を貫通するボルト38にナット39を締結してブラケット本体21に楔体3Aを固着する。この楔体3Aはブラケット本体21の両端部に装着されており、対峙する支柱1{具体的には、支柱体10(10A)}に固着された対向する楔受け部材2に楔着されることによってブラケット20を強固に取り付けることができるようになっている。なお、楔体3Aは必ずしもブラケット本体21の両端部に装着する必要はなく、少なくともブレース24の基端側に位置する端部に装着されていればよい。なお、楔体3Aも、楔体3と同様に、先端側の支柱当接面3aには、支柱体10の外周面と相似形状の凹状面3bが形成されている(図11(a)参照)。   In this case, the wedge body 3 </ b> A is formed by an attachment tube portion 35 fitted to the bracket body 21 and a wedge portion 36 fixed to the attachment tube portion 35 by, for example, welding or integrally formed. In order to attach the wedge body 3A to the bracket main body 21, a nut 39 is fastened to the bracket main body 21 by fastening a nut 39 to a bolt 38 passing through a mounting cylinder portion 35 and a through hole (not shown) drilled in the bracket main body 21. The wedge body 3A is fixed. The wedge body 3A is attached to both ends of the bracket main body 21 and is wedged to the opposing wedge receiving member 2 fixed to the opposing strut 1 {specifically, the strut body 10 (10A)}. Thus, the bracket 20 can be firmly attached. The wedge body 3 </ b> A does not necessarily have to be attached to both ends of the bracket body 21, and may be attached to at least the end located on the base end side of the brace 24. Similarly to the wedge body 3, the wedge body 3 </ b> A is also formed with a concave surface 3 b similar to the outer peripheral surface of the column body 10 on the column contact surface 3 a on the distal end side (see FIG. 11A). ).

一方、上記足場板40は、図12及び図13に示すように、長手方向に沿う複数例えば7個(列)の凸部41a,41bを有する凹凸状の踏み板部41と、この踏み板部41の両端から下面に垂下する一対の断面略L字状の補強側壁片42と、踏み板部41の下面中間部の両側に垂下する互いに平行な2列の断面略矩形状の中空補強部43とを具備するアルミニウム製押出形材にて形成されている。また、足場板40の踏み板部41の凸部41a,41bには、適宜間隔をおいて多数の滑り止め兼用の水抜き孔44a,44bが穿設されている。この場合、両中空補強部43の間には3列の凸部41aが形成され、中空補強部43より外側には凸部41aより幅広の2列の凸部41bが形成されており、凸部41aには略方形状の水抜き孔44aが狭いピッチ間隔で穿設され、また、凸部41bには長手方向が長い略矩形状の水抜き孔44bが同じく狭いピッチ間隔で穿設されている。したがって、足場板40の踏み板部41は、開口率(例えば37%)の大きい水抜き孔44a,44bが形成されるので、滑り難い上、表面に汚れが付き難く、しかも、建物の壁を汚す雨だれの跳ね返りを防止することができる。   On the other hand, as shown in FIGS. 12 and 13, the scaffold plate 40 includes an uneven tread plate portion 41 having a plurality of, for example, seven (rows) convex portions 41 a and 41 b along the longitudinal direction, and the tread plate portion 41. A pair of substantially L-shaped reinforcing side wall pieces 42 that hang down from both ends to the lower surface, and two parallel rows of hollow reinforcing portions 43 that are parallel to each other and hang down on both sides of the lower surface middle portion of the tread plate 41 are provided. It is made of an aluminum extruded profile. In addition, a number of drainage holes 44a and 44b, which are also used as anti-skids, are formed in the convex portions 41a and 41b of the tread plate portion 41 of the scaffold plate 40 at appropriate intervals. In this case, three rows of convex portions 41 a are formed between the hollow reinforcing portions 43, and two rows of convex portions 41 b wider than the convex portions 41 a are formed outside the hollow reinforcing portions 43. 41a is formed with substantially rectangular drain holes 44a with a narrow pitch interval, and the convex part 41b is provided with substantially rectangular drain holes 44b with a long longitudinal direction at a narrow pitch interval. . Accordingly, since the drainage holes 44a and 44b having a large opening ratio (for example, 37%) are formed in the step board portion 41 of the scaffold board 40, it is difficult to slip, the surface is difficult to get dirty, and the wall of the building is soiled. It can prevent the raindrop from bouncing off.

また、足場板40における長手方向の両端部にはアルミニウム製の塞ぎ板45が溶接等によって固着されている。この塞ぎ板45を介して足場板40の一側には、長手方向の外方に突出するステンレス鋼製のフック金具46がボルト47及びナット48によって固定されている。また、足場板40における長手方向の両端部の他側部には、ブラケット20に設けられた楔受け部材2Aに挿入されるステンレス鋼製の楔体3Bが溶接等によって固着されている。なお、塞ぎ板45における中空補強部43を塞ぐ部位には、水抜き孔49が設けられている。   In addition, an aluminum closing plate 45 is fixed to both ends of the scaffold plate 40 in the longitudinal direction by welding or the like. A stainless steel hook metal fitting 46 protruding outward in the longitudinal direction is fixed to one side of the scaffolding plate 40 through the closing plate 45 by bolts 47 and nuts 48. Further, a stainless steel wedge body 3B inserted into a wedge receiving member 2A provided on the bracket 20 is fixed to the other side of both ends of the scaffold plate 40 in the longitudinal direction by welding or the like. A drain hole 49 is provided at a portion of the closing plate 45 that closes the hollow reinforcing portion 43.

次に、この発明に係る足場の一例の組立手順について説明する。まず、ジャッキベース部材4と最下段の支柱体例えば鉄製支柱体10Aを連結する。次に、支柱体10Aの小径部11Aにロックピン50を取り付ける。ロックピン50を取り付けるには、弾性力に抗して押圧して両第1及び第2の傾斜片52,54を近づけて、支柱体10Aの小径部11A内に挿入した後、押圧力を解除して、小径部11Aに設けられた窓孔13内から屈曲部53を外方に突出した状態にセットする。なお、ロックピン50を予め支柱体10Aの小径部11Aに取り付けておいてもよい。この状態で、支柱体10Aを立て、ジャッキベース部材4を図示しないアンカで固定して、複数の支柱体10Aを適時間隔に設置する。   Next, an assembly procedure of an example of the scaffold according to the present invention will be described. First, the jack base member 4 and the lowermost support column, for example, an iron support 10A are connected. Next, the lock pin 50 is attached to the small diameter portion 11A of the column body 10A. To attach the lock pin 50, press against the elastic force to bring both the first and second inclined pieces 52 and 54 close together and insert them into the small diameter portion 11A of the column body 10A, and then release the pressing force. Then, the bent portion 53 is set in a state of protruding outward from the inside of the window hole 13 provided in the small diameter portion 11A. In addition, you may attach the lock pin 50 to the small diameter part 11A of 10 A of support | pillar bodies previously. In this state, the column body 10A is erected, the jack base member 4 is fixed with an anchor (not shown), and the plurality of column bodies 10A are installed at appropriate intervals.

次に、支柱体10Aにブラケット20を取り付ける。この際、ブラケット20の楔体3Aをハンマで叩いて支柱体10Aに固着された楔受け部材2に楔着して、ブラケット20を取り付ける。同様にして各支柱体10Aにブラケット20を取り付ける。   Next, the bracket 20 is attached to the column body 10A. At this time, the wedge body 3A of the bracket 20 is hit with a hammer to be wedged on the wedge receiving member 2 fixed to the support body 10A, and the bracket 20 is attached. Similarly, the bracket 20 is attached to each column 10A.

次に、隣接する支柱体10Aに取り付けられたブラケット20間に足場板40を架設する。この際、足場板40に設けられた楔体3Bをハンマで叩いてブラケット20に固着された楔受け部材2に楔着すると共に、足場板40に設けられたフック金具46をブラケット本体21に引っ掛けて足場板40を強固に架設することができる。   Next, the scaffolding plate 40 is installed between the brackets 20 attached to the adjacent column bodies 10A. At this time, the wedge body 3B provided on the scaffold plate 40 is hit with a hammer to be wedged on the wedge receiving member 2 fixed to the bracket 20, and the hook metal fitting 46 provided on the scaffold plate 40 is hooked on the bracket body 21. Thus, the scaffold plate 40 can be firmly installed.

次に、架設された足場板40を利用して隣接する支柱体10Aに手摺30を取り付ける。この際、手摺30に設けられた楔体3をハンマで叩いて支柱体10Aに固着された楔受け部材2に楔着して、手摺30を強固に取り付けることができる。   Next, the handrail 30 is attached to the supporting column body 10A using the installed scaffolding plate 40. At this time, the handrail 30 can be firmly attached by hitting the wedge body 3 provided on the handrail 30 with a hammer to be wedged on the wedge receiving member 2 fixed to the column body 10A.

また、足場板40を利用して支柱体10Aの先端小径部11Aに2段目の支柱体例えばアルミニウムパイプ製支柱体10を連結する。この際、支柱体10の下端の拡管部12内に小径部11Aを嵌挿させると、ロックピン50の屈曲部53が支柱体10の係合孔14に係合して支柱体10が固定される。これにより、支柱体10は回転が阻止されると共に、不用意に抜けることがなくなる。このようにして、各支柱体10Aの小径部11Aに拡管部12を嵌挿して支柱体10を連結する。   Further, a second-stage strut body, for example, an aluminum pipe strut body 10 is connected to the small-diameter portion 11A at the tip end of the strut body 10A using the scaffold plate 40. At this time, when the small-diameter portion 11A is inserted into the expanded tube portion 12 at the lower end of the column body 10, the bent portion 53 of the lock pin 50 engages with the engagement hole 14 of the column body 10, and the column body 10 is fixed. The As a result, the column body 10 is prevented from rotating and is not accidentally pulled out. In this manner, the expanded tube portion 12 is inserted into the small diameter portion 11A of each support column 10A, and the support columns 10 are connected.

次に、支柱体10に、上記と同様にブラケット20を取り付ける。すなわち、ブラケット20の楔体3Aをハンマで叩いて支柱体10に固着された楔受け部材2に楔着して、ブラケット20を取り付ける。同様にして各支柱体10にブラケット20を取り付ける。   Next, the bracket 20 is attached to the support 10 in the same manner as described above. That is, the wedge body 3 </ b> A of the bracket 20 is hit with a hammer to be wedged on the wedge receiving member 2 fixed to the column body 10, and the bracket 20 is attached. Similarly, the bracket 20 is attached to each column body 10.

次に、隣接する支柱体10に取り付けられたブラケット20間に、上記と同様に足場板40を架設する。すなわち、足場板40に設けられた楔体3Bをハンマで叩いてブラケット20に固着された楔受け部材2に楔着すると共に、足場板40に設けられたフック金具46をブラケット本体21に引っ掛けて足場板40を強固に架設する。   Next, the scaffolding plate 40 is constructed between the brackets 20 attached to the adjacent support columns 10 in the same manner as described above. That is, the wedge body 3B provided on the scaffold board 40 is hit with a hammer to be wedged on the wedge receiving member 2 fixed to the bracket 20, and the hook metal fitting 46 provided on the scaffold board 40 is hooked on the bracket body 21. The scaffold board 40 is firmly constructed.

架設された足場板40を利用して隣接する支柱体10に、上記と同様に手摺30を取り付ける。すなわち、手摺30に設けられた楔体3をハンマで叩いて支柱体10に固着された楔受け部材2に楔着して、手摺30を強固に取り付けることができる。   The handrail 30 is attached to the adjacent column 10 using the scaffolding plate 40 constructed in the same manner as described above. That is, the handrail 30 can be firmly attached by hitting the wedge body 3 provided on the handrail 30 with a hammer to be wedged on the wedge receiving member 2 fixed to the support body 10.

以下、同様に、足場板40を利用して、支柱体10の小径部11にロックピン50を介して支柱体10を嵌挿固定し、各支柱体10にブラケット20を取り付けると共に、ブラケット20間に足場板40を架設し、更に、隣接する支柱体10間に手摺30を取り付けて、所定の高さの足場を組み立てる。   Hereinafter, similarly, using the scaffold plate 40, the support body 10 is fitted and fixed to the small diameter portion 11 of the support body 10 via the lock pin 50, and the bracket 20 is attached to each support body 10. A scaffolding plate 40 is installed on the frame, and a handrail 30 is attached between the adjacent column bodies 10 to assemble a scaffold having a predetermined height.

上記のようにして組み立てられた足場は、最下段に鉄製の支柱体10Aを位置させ、その上方にアルミニウムパイプ製の支柱体10を使用し、また、ブラケット20はアルミニウム製のブラケット本体21を有し、手摺30においてもアルミニウムパイプからなる手摺本体31を有するので、足場構成部材を軽量化することができ、高所での作業を容易にすると共に、安全に行うことができる。また、支柱体10においても肉厚に形成されているので、強度が得られる。また、ブラケット20及び手摺30においては、ブラケット本体21及び手摺本体31の上下部に肉厚部22,32が形成され、しかも、アルミダイキャスト製の楔体3,3Aを装着してなるため、取り付ける際にハンマで叩いても変形する虞がなく、十分な強度が得られるので、寿命の増大が図れ、繰り返し使用することができる。また、手摺30は、手摺本体31と楔体3とを連結(締結)するボルト38の頭部38a及びナット39を凹状部34内に納めているので、手摺30からの突起部をできる限り少なくすることができ、作業者が不用意に手を引っ掛けたり、衣服を引っ掛ける心配がなく、作業を安全にすることができる。   In the scaffold assembled as described above, the iron support 10A is positioned at the bottom, the aluminum pipe support 10 is used above, and the bracket 20 has an aluminum bracket body 21. However, since the handrail 30 also has the handrail main body 31 made of an aluminum pipe, it is possible to reduce the weight of the scaffold component, facilitate the work at a high place, and perform it safely. Moreover, since the support column 10 is also formed thick, strength can be obtained. Further, in the bracket 20 and the handrail 30, the thick portions 22 and 32 are formed on the upper and lower portions of the bracket main body 21 and the handrail main body 31, and the wedge bodies 3 and 3A made of aluminum die cast are mounted. There is no risk of deformation even if it is struck with a hammer at the time of attachment, and sufficient strength can be obtained, so that the life can be increased and it can be used repeatedly. Further, since the handrail 30 stores the head portion 38a and the nut 39 of the bolt 38 for connecting (fastening) the handrail body 31 and the wedge body 3 in the concave portion 34, the number of protrusions from the handrail 30 is reduced as much as possible. Therefore, there is no worry that an operator carelessly catches hands or clothes, and the work can be made safe.

足場を解体する場合は、手摺30と足場板40とブラケット20においては、楔体3,3Aの取付筒部35の下面等をハンマで叩いて楔体3,3A,3Bと楔受け部材2(2A)との楔着を解いて、手摺30、足場板40及びブラケット20を順に取り外す。また、支柱1を解体する場合は、上述したように、支柱体10(10A)をロックピン50の第1及び第2の傾斜片52,54の傾き方向に回転する(捻る)ことにより、ロックピン50の固定を解除して、支柱体10(10A)を取り外す。   When disassembling the scaffold, in the handrail 30, the scaffold plate 40, and the bracket 20, the lower surfaces of the mounting cylinder portions 35 of the wedge bodies 3 and 3A are hit with a hammer to form the wedge bodies 3, 3A, 3B and the wedge receiving member 2 ( 2A), the handrail 30, the scaffold plate 40, and the bracket 20 are removed in order. Further, when disassembling the support 1, as described above, the support 10 (10 </ b> A) is locked by rotating (twisting) the first and second inclined pieces 52 and 54 of the lock pin 50 in the direction of inclination. The fixing of the pin 50 is released, and the column body 10 (10A) is removed.

足場を解体する場合においても、支柱体10がアルミニウム製であり、また、ブラケット20はアルミニウム製のブラケット本体21を有し、手摺30においてもアルミニウムパイプからなる手摺本体31を有するので、高所での作業を容易にすると共に、安全に行うことができる。また、ブラケット20及び手摺30においては、ブラケット本体21及び手摺本体31の上下部に肉厚部22,32が形成され、しかも、アルミダイキャスト製の楔体3,3Aを装着してなるため、取り外しの際にハンマで叩いても変形する虞がなく、十分な強度が得られるので、寿命の増大が図れ、繰り返し使用することができる。   Even when the scaffold is dismantled, the support 10 is made of aluminum, the bracket 20 has an aluminum bracket body 21, and the handrail 30 also has a handrail body 31 made of an aluminum pipe. This can be done easily and safely. Further, in the bracket 20 and the handrail 30, the thick portions 22 and 32 are formed on the upper and lower portions of the bracket main body 21 and the handrail main body 31, and the wedge bodies 3 and 3A made of aluminum die cast are mounted, There is no risk of deformation even if it is struck with a hammer at the time of removal, and sufficient strength can be obtained, so that the life can be increased and it can be used repeatedly.

なお、上記説明では、最下段に鉄製の支柱体10Aを位置させ、その上方にアルミニウム製の支柱体10を位置させる場合について説明したが、鉄製の支柱体10Aとアルミニウムパイプ製の支柱体10とは互換性があり、しかも支柱体10は肉厚に形成されて強度性を有するので、適宜選択して支柱1を構成することは可能である。   In the above description, the case where the iron support 10A is positioned at the bottom and the aluminum support 10 is positioned above the bottom is described. However, the iron support 10A and the aluminum pipe support 10 Are compatible with each other, and the column body 10 is formed thick and has strength, so that the column 1 can be configured by appropriately selecting.
