Description

本発明は、例えば建築現場等で組み立てられる仮設足場において、現場作業者が足場板から転落するのを防止するための仮設足場用手摺に関するものである。  The present invention relates to a temporary scaffolding handrail for preventing a site worker from falling from a scaffolding plate in a temporary scaffolding assembled at a construction site, for example.

従来、仮設足場は、例えばビル等の建築工事現場において建築物に沿うようにして設けられ、現場作業者が建築物の補修等の工事を行うために用いられる。仮設足場としては、各部材の連結に例えばくさびが用いられたくさび緊結式足場が知られている(例えば特許文献1参照)。  Conventionally, a temporary scaffold is provided along a building, for example, at a construction site such as a building, and is used for a site worker to perform construction such as repairing the building. As a temporary scaffold, there is known a wedge-tight scaffold in which, for example, a wedge is used to connect each member (see, for example, Patent Document 1).

くさび緊結式足場では、建築物の外面に沿って上下方向に複数の支柱が設けられ、隣り合う支柱同士の間に現場作業者が通行するための足場板や、現場作業者が足場板から転落するのを防止するための仮設足場用手摺等が敷設される。  In wedge-tight scaffolds, multiple pillars are provided in the vertical direction along the outer surface of the building. Scaffolding plates for on-site workers to pass between adjacent struts, and on-site workers falling from the scaffolding plates A handrail for temporary scaffolding or the like for preventing this is laid.

図8は、支柱及びそれに取付けられた仮設足場用手摺の一例を示す図である。同図によると、左右方向に所定の間隔を隔てて複数の支柱31が立設されており、支柱31には、例えば複数のフランジ32が高さ方向に所定の間隔を隔てて設けられている。これら隣り合う支柱1の複数のフランジ32には、これらを利用して仮設足場用手摺33(以下、単に「手摺33」という。)が取付けられる。  FIG. 8 is a diagram illustrating an example of a support pillar and a handrail for a temporary scaffold attached thereto. According to the figure, a plurality of support posts 31 are erected with a predetermined interval in the left-right direction, and for example, a plurality of flanges 32 are provided on the support column 31 with a predetermined interval in the height direction. . Temporary scaffolding handrails 33 (hereinafter simply referred to as “handrails 33”) are attached to the plurality of flanges 32 of the adjacent struts 1 using these.

手摺33は、例えば水平方向に延び、通常、安全帯等が掛着される水平材34と、水平材34の両端に設けられフランジ32に掛止される掛止フック35と、各掛止フック35に一端側が接続され、各掛止フック35にそれぞれ回動自在に支持された2本の斜材36と、斜材36の他端側に設けられフランジ32に斜材36を固定するための固定部材37とによって構成される。  The handrail 33 extends, for example, in the horizontal direction, and generally includes a horizontal member 34 to which a safety belt or the like is hooked, hook hooks 35 provided at both ends of the horizontal member 34 and hooked to the flange 32, and the hooks. 35 is connected to one end side of each of the hooks 35 so as to be rotatably supported by the respective hooks 35, and the diagonal member 36 is fixed to the flange 32 provided on the other end side of the diagonal member 36. And a fixing member 37.

手摺33では、フランジ32に形成された係止孔(図略)に2つの掛止フック35がそれぞれ掛止される。また、他のフランジ32の係止孔に2つの固定部材37のクサビ38が打ち込まれて2つの固定部材37がそれぞれ固着される。これにより、手摺33は、隣り合う支柱31間に取付けられる。なお、例えば固定部材37が固定された高さ位置には、ほぼ同じ高さに足場板39が敷設される。  In the handrail 33, two latching hooks 35 are respectively latched in locking holes (not shown) formed in the flange 32. Further, the wedges 38 of the two fixing members 37 are driven into the locking holes of the other flanges 32 and the two fixing members 37 are fixed to each other. Thereby, the handrail 33 is attached between the adjacent columns 31. For example, a scaffold plate 39 is laid at substantially the same height at the height position where the fixing member 37 is fixed.

上記手摺33は、現場作業者が足場板39から転落するのを防止するために設けられるが、近年、日本人の平均身長は伸び傾向にあり、現場作業者の作業中の安心感を与える観点からも、足場板39から水平材34までの高さH0を適切な高さ位置まで高くしてほしいといった要請がある。  The handrail 33 is provided in order to prevent the field worker from falling from the scaffolding plate 39. In recent years, the average height of Japanese people tends to increase, and the viewpoint that gives the field worker a sense of security during work. Therefore, there is a request for increasing the height H0 from the scaffold plate 39 to the horizontal member 34 to an appropriate height position.

図9は、そのような要請に応えた仮設足場用手摺の他の例を示す図である。なお、同図に示す支柱31には、図8に示すフランジ32に代えて中空状のポケット40が設けられ、手摺33Aはポケット40に取付けられる。  FIG. 9 is a diagram showing another example of a handrail for temporary scaffolding that meets such a request. The column 31 shown in the figure is provided with a hollow pocket 40 instead of the flange 32 shown in FIG. 8, and the handrail 33 </ b> A is attached to the pocket 40.

同図によると、水平材34Aの両端は、掛止フック35Aの上部から上方に延びかつ湾曲して形成され、中央の水平部分が図8に示す手摺33に比べ、その高さ位置が高くなるようにされている。そのため、この手摺33Aを用いれば、水平材34Aの水平部分の高さ位置が高くなるので、現場作業者に安心感を与えることができる。  According to the figure, both ends of the horizontal member 34A extend upward from the upper portion of the latching hook 35A and are curved, and the height of the central horizontal portion is higher than that of the handrail 33 shown in FIG. Has been. Therefore, if this handrail 33A is used, since the height position of the horizontal part of the horizontal member 34A becomes high, a sense of security can be given to the field worker.

ところで、上記の手摺33,33Aでは、運搬時や梱包時において支柱31から取り外された場合、斜材36が掛止フック35,35Aを基点にして回動されることにより折り畳まれる。そして、通常、複数の手摺33,33Aが束ねられて運搬、梱包される。  By the way, when the handrails 33 and 33A are detached from the support column 31 during transportation or packing, the diagonal members 36 are folded by being rotated with the hooks 35 and 35A as the base point. Usually, a plurality of handrails 33, 33A are bundled and transported and packed.

ところが、図9に示す手摺33Aでは、水平材34Aの両端が湾曲して形成されているため、運搬時や梱包時に折り畳まれたとき、図10に示すように、水平材34Aのための平面的なスペースが必要となり全体的に嵩張ることになる。そのため、運搬時や梱包時に手摺33Aを束ねるようにしても、広範な梱包スペースを要するといった問題点がある。  However, in the handrail 33A shown in FIG. 9, both ends of the horizontal member 34A are curved, so that when folded at the time of transportation or packing, as shown in FIG. A large space is required and the whole is bulky. Therefore, even if the handrails 33A are bundled during transportation or packing, there is a problem that a wide packing space is required.

それに対し、図8に示す手摺33は、図11に示すように、折り畳まれた状態では略棒状となる。そのため、運搬時や梱包時には、複数の手摺33を束ねても密な状態となり、その梱包スペースも比較的コンパクトとされる。  On the other hand, as shown in FIG. 11, the handrail 33 shown in FIG. 8 is substantially rod-shaped in the folded state. Therefore, when carrying or packing, a plurality of handrails 33 are bundled to form a dense state, and the packing space is relatively compact.

しかしながら、上記手摺33の運搬時や梱包時では、以下の問題点がある。すなわち、上記手摺33では、斜材36が掛止フック35を基点にして回動されて折り畳まれるが、図12に示すように、斜材36が水平材34側に回動し過ぎて水平材34と交差してしまうことが多い。  However, when the handrail 33 is transported or packed, there are the following problems. That is, in the handrail 33, the diagonal member 36 is rotated and folded with the latch hook 35 as a base point, but as shown in FIG. 12, the diagonal member 36 is excessively rotated toward the horizontal member 34 and the horizontal member 36 is folded. Often crosses 34.

そのため、例えば複数の手摺33を束ねて梱包された状態から一つの手摺33を取り出すとき、斜材36のみや水平材34のみを手で把持して引っ張り出すと、図12に示す状態になり、手摺33同士が絡み合って、一つの手摺33の取り出しがスムーズにできないといったことがある。  Therefore, for example, when one handrail 33 is taken out from a state in which a plurality of handrails 33 are bundled and packed, if only the diagonal member 36 or only the horizontal member 34 is gripped and pulled out, the state shown in FIG. 12 is obtained. In some cases, the handrails 33 are entangled with each other and one handrail 33 cannot be taken out smoothly.

すなわち、複数の手摺33から一つの手摺33を取り出すとき、水平材34及び2本の斜材36をまとめて把持して取り出せばよいのであるが、手摺33と他の手摺33の部材同士が混在して絡み合っていると、どの部材が一つの手摺33を構成するのかが現場作業者には不明となり、手摺33の取り出しが非常に困難となる。  That is, when one handrail 33 is taken out from a plurality of handrails 33, the horizontal member 34 and the two diagonal members 36 may be grasped and taken out together, but the members of the handrail 33 and the other handrails 33 are mixed. If they are intertwined, it becomes unclear to the field worker which member constitutes one handrail 33, and it is very difficult to take out the handrail 33.

また、複数の手摺33から一つの手摺33を取り出すとき、手摺33と他の手摺33の部材同士が混在して絡み合っていると、斜材36と水平材34との間に手を挟んだり、斜材36の一端が広がり過ぎてその端部が他の障害物と衝突し損傷したりすることが生じる。  Further, when taking out one handrail 33 from a plurality of handrails 33, if the members of the handrail 33 and the other handrail 33 are mixed and intertwined, a hand is sandwiched between the diagonal member 36 and the horizontal member 34, One end of the diagonal member 36 is excessively widened, and the end portion collides with another obstacle and is damaged.

さらに、斜材36が水平材34側に回動し過ぎて水平材34と交差してしまう状態は、斜材36の回動軸と水平材34との距離が離れているほど、斜材36が水平材34の反対側に回動する角度が大きくなる。そのため、図9に示した水平材34Aの両端が湾曲状になった手摺33Aでは、その傾向がより顕著となり、手摺33Aの取り出しがより困難になるといった問題点がある。  Further, the state in which the diagonal member 36 rotates too far to the horizontal member 34 and intersects the horizontal member 34 is such that the longer the distance between the rotation shaft of the diagonal member 36 and the horizontal member 34 is, the longer the diagonal member 36 is. The angle at which the shaft rotates to the opposite side of the horizontal member 34 increases. Therefore, in the handrail 33A in which both ends of the horizontal member 34A shown in FIG. 9 are curved, the tendency becomes more conspicuous, and there is a problem that it is more difficult to take out the handrail 33A.

特開2011−111888号公報JP 2011-111888 A

本発明は、上記した事情のもとで考え出されたものであって、水平材の高さ位置についての要請に応えつつ折り畳み時に斜材が水平材側に必要以上に回動することのない仮設足場用手摺を提供することをその課題とする。  The present invention has been conceived under the circumstances described above, and the diagonal member does not rotate more than necessary to the horizontal member side when folded while responding to the request for the height position of the horizontal member. An object is to provide a handrail for a temporary scaffold.

本発明によって提供される仮設足場用手摺は、所定の間隔を隔てて立設された隣り合う支柱間に、前記支柱に設けられる被嵌挿体に対して取付けられることにより敷設される仮設足場用手摺であって、略水平方向に延びた水平材と、前記水平材の少なくとも一端近傍に下方向に延びて設けられた延出部材と、前記延出部材の下部に回動自在に支持されるとともに、前記支柱に取付けられた状態では両端が前記支柱の前記被嵌挿体に保持される略棒状の斜材と、前記斜材が前記水平材側に回動されるとき、その回動角度を規制する規制部材と、を備えることを特徴としている。  A handrail for a temporary scaffold provided by the present invention is for a temporary scaffold laid by being attached to a fitting insert provided on the support between adjacent support columns that are erected at a predetermined interval. A handrail, which is supported by a horizontal member extending in a substantially horizontal direction, an extending member extending downward at least near one end of the horizontal member, and a lower portion of the extending member. In addition, when mounted on the support column, both ends of the support member are held by the fitted inserts of the support column, and the angle of rotation of the diagonal member is rotated to the horizontal member side. And a restricting member for restricting the pressure.

本発明の仮設足場用手摺において、前記延出部材は、前記水平材の延出方向に沿った面を有する本体からなり、前記規制部材は、前記本体の表面と直交する方向に延出された当接片からなり、前記斜材は、前記水平材側に回動されるとき、所定の回動角度で前記当接片に当接されるとよい。  In the handrail for a temporary scaffold according to the present invention, the extending member includes a main body having a surface along the extending direction of the horizontal member, and the restricting member extends in a direction orthogonal to the surface of the main body. It is preferable that the diagonal member is made of an abutment piece, and the diagonal member is brought into contact with the abutment piece at a predetermined rotation angle when being rotated to the horizontal material side.

本発明の仮設足場用手摺において、前記当接片は、前記斜材が前記当接片に当接されたとき、前記水平材及び前記斜材が略棒状になるように、上下方向の長さが設定されているとよい。  In the handrail for a temporary scaffold according to the present invention, the contact piece has a length in the vertical direction so that the horizontal member and the diagonal member are substantially rod-shaped when the diagonal member is in contact with the contact piece. Should be set.

本発明の仮設足場用手摺において、前記斜材の一端には、前記被嵌挿体に形成された係止孔に掛止されるフックが形成されており、前記斜材の他端には、前記被嵌挿体とは異なる他の被嵌挿体に形成された係止孔に固定される固定部材が設けられているとよい。  In the temporary scaffolding handrail of the present invention, one end of the diagonal member is formed with a hook that is hooked in a locking hole formed in the fitted insert, and the other end of the diagonal member is It is good to provide the fixing member fixed to the latching hole formed in the other to-be-inserted body different from the said to-be-inserted body.

本発明の仮設足場用手摺において、前記被嵌挿体は、少なくとも一つの係止孔を有するフランジであるとよい。  In the temporary scaffolding handrail of the present invention, the fitted insert may be a flange having at least one locking hole.

本発明によれば、仮設足場用手摺は、水平材に対して延出部材が下方向に延びて設けられているので、足場板の表面から水平材までの高さを、従来の構成に比べ高くすることができ、現場作業者の安心感を高めることができる。また、仮設足場用手摺が折り畳まれて斜材が回動されたとき、当接片が斜材の回動角度を規制するため、仮設足場用手摺は、略棒状の状態となる。そのため、例えば複数の仮設足場用手摺を束ねて梱包された状態から一つの仮設足場用手摺を取り出すときであっても、仮設足場用手摺同士が絡み合う可能性を低くすることができ、従来の構成に比べ、よりスムーズに取り出すことができる。  According to the present invention, since the handrail for the temporary scaffold is provided with the extending member extending downward with respect to the horizontal member, the height from the surface of the scaffold plate to the horizontal member is compared with the conventional configuration. It can be raised and the safety of the field worker can be enhanced. Further, when the handrail for temporary scaffolding is folded and the diagonal member is rotated, the contact piece regulates the rotation angle of the diagonal member, so that the temporary scaffolding handrail is in a substantially rod-like state. Therefore, for example, even when one temporary scaffolding handrail is taken out from a state where a plurality of temporary scaffolding handrails are bundled and packed, the possibility that the temporary scaffolding handrails may be entangled with each other can be reduced. Compared to, it can be taken out more smoothly.

また、仮設足場用手摺を取り出すとき、斜材と水平材との間に手を挟んだり、斜材の一端が広がり過ぎてその端部が他の障害物と衝突して損傷したりすることを抑制することができる。さらに、複数の仮設足場用手摺を梱包する際にも、一つの仮設足場用手摺が略棒状となるため、複数の仮設足場用手摺を整然と並べて梱包することができ、また梱包スペースを極力コンパクトにすることができる。  Also, when removing the handrail for temporary scaffolding, it is possible that your hand is sandwiched between the diagonal material and the horizontal material, or one end of the diagonal material is too wide and the end collides with other obstacles and is damaged. Can be suppressed. In addition, when packaging a plurality of temporary scaffolding handrails, one temporary scaffolding handrail has a substantially rod-like shape, so that a plurality of temporary scaffolding handrails can be ordered and packed, and the packaging space can be made as compact as possible. can do.

以下、本発明の実施の形態につき、図面を参照して具体的に説明する。  Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.

図1は、本発明に係る仮設足場用手摺が支柱に取付けられた状態を示す側面図である。図2は、図1に示す仮設足場用手摺の掛止部を示す部分側面図である。図3は、図1に示す仮設足場用手摺の掛止部を示す部分平面図である。  FIG. 1 is a side view showing a state in which a handrail for temporary scaffolding according to the present invention is attached to a support column. FIG. 2 is a partial side view showing a latching portion of the handrail for temporary scaffold shown in FIG. FIG. 3 is a partial plan view showing a latching portion of the handrail for the temporary scaffold shown in FIG.

本発明に係る仮設足場用手摺は、例えばクサビ緊結式足場に適用される。クサビ緊結式足場においては、水平方向に所定の間隔を隔てて立設された複数の支柱1を備えている。各支柱1には、上下方向に所定の間隔を隔てて複数の被嵌挿体としてのフランジ2が設けられている。  The handrail for temporary scaffolding according to the present invention is applied to, for example, a wedge-tight scaffold. The wedge-tightened scaffold includes a plurality of support columns 1 that are erected at predetermined intervals in the horizontal direction. Each support column 1 is provided with a plurality of flanges 2 serving as fitting inserts at predetermined intervals in the vertical direction.

フランジ2は、図3に示すように、平面視で略花びら状に形成され、中央に支柱1が貫通する円形孔2aが形成され、円形孔2aから四方に延びた係止孔2bがそれぞれ形成されている。係止孔2bは、先端近傍の左右方向にそれぞれ凸部を有し、この係止孔2bには、後述する斜材12の掛止部14やくさび19が嵌装される。  As shown in FIG. 3, the flange 2 is formed in a substantially petal shape in plan view, a circular hole 2 a through which the support column 1 passes is formed in the center, and a locking hole 2 b extending in all directions from the circular hole 2 a is formed. Has been. The locking hole 2b has convex portions in the left and right directions near the tip, and a locking portion 14 and a wedge 19 of the diagonal member 12 to be described later are fitted into the locking hole 2b.

隣り合う支柱1間には、図1に示すように、仮設足場用手摺10(以下、単に「手摺10」という。)が敷設される。また、手摺10の後述する固定部16が取付けられる高さ位置には、現場作業者が歩行するための足場板3が取付けられる。  As shown in FIG. 1, a temporary scaffolding handrail 10 (hereinafter simply referred to as “handrail 10”) is laid between adjacent struts 1. Moreover, the scaffold board 3 for a field worker to walk is attached to the height position where the fixing | fixed part 16 mentioned later of the handrail 10 is attached.

手摺10は、主として現場作業者が足場板3から転落することを防止するためのものである。手摺10は、略水平方向に延びる水平材11と、水平材11の一方端側及び他方端側にそれぞれ接続された2本の斜材12とを備えている。  The handrail 10 is mainly for preventing a field worker from falling from the scaffold plate 3. The handrail 10 includes a horizontal member 11 extending in a substantially horizontal direction, and two diagonal members 12 connected to one end side and the other end side of the horizontal member 11, respectively.

水平材11は、現場作業者が手摺として利用したり安全帯を掛着させたりする部材として用いられる。水平材11は、所定長さを有する略円筒状のパイプ材であり、隣り合う支柱1の間の長さ(例えば約1.8m)よりやや短く形成されている。  The horizontal member 11 is used as a member that can be used as a handrail by a site worker or to attach a safety belt. The horizontal member 11 is a substantially cylindrical pipe member having a predetermined length, and is formed slightly shorter than the length between adjacent struts 1 (for example, about 1.8 m).

水平材11の一方端及び他方端のそれぞれの湾曲下面には、延出部材13が例えば溶接によってそれぞれ接合されている。延出部材13は、例えば足場板3からの水平材11の高さを嵩上げするとともに、斜材12を水平材11側に回動させたときに斜材12が必要以上に回動することを防止するためのものである。  The extending members 13 are joined to the curved lower surfaces of the one end and the other end of the horizontal member 11 by, for example, welding. The extending member 13 raises the height of the horizontal member 11 from the scaffold plate 3, for example, and when the diagonal member 12 is rotated to the horizontal member 11 side, the diagonal member 12 rotates more than necessary. It is for preventing.

延出部材13は、図3に示すように、平面視で略L字状に形成されている。延出部材13は、水平材11の延出方向に平行にかつ上下方向に延びて形成され、側面視(図2参照)で略長靴状に形成された本体13aと、本体13aの支柱1側とは反対側の一辺から水平材11の本体13aの表面と直交する方向に延びて形成された当接片13bとを有する。  As shown in FIG. 3, the extending member 13 is formed in a substantially L shape in plan view. The extending member 13 is formed so as to extend in the vertical direction parallel to the extending direction of the horizontal member 11, and is formed in a substantially boot-like shape when viewed from the side (see FIG. 2), and the column 1 side of the main body 13a. And a contact piece 13b formed so as to extend in a direction orthogonal to the surface of the main body 13a of the horizontal member 11 from one side on the opposite side.

当接片13bは、斜材12が折り畳まれて回動されたとき、その回動角度を規制する、すなわち斜材12が必要以上に回動することを規制するためのものである。当接片13bの幅(図2における奥行方向の長さ)は、平面視(図3参照)で水平材11の外表面から突出しないような長さとされている。換言すれば、当接片13bの幅は、斜材12を回動させたときに斜材12と当接されるのに十分な長さとされている。  The contact piece 13b is for restricting the rotation angle of the diagonal member 12 when the diagonal member 12 is folded and rotated, that is, for restricting the diagonal member 12 from rotating more than necessary. The width of the contact piece 13b (the length in the depth direction in FIG. 2) is set so as not to protrude from the outer surface of the horizontal member 11 in plan view (see FIG. 3). In other words, the width of the contact piece 13b is long enough to contact the diagonal member 12 when the diagonal member 12 is rotated.

延出部材13の本体13aの下部には、斜材12が回動軸13cを中心にして回動自在に支持されている。斜材12は、それを支柱1のフランジ2に掛止させるための掛止部14と、長尺状の長尺部15と、手摺10をフランジ2に固定させるための固定部16とを備えている。長尺部15の一端には、掛止部14が例えば溶接で接合され、長尺部15の他端には、固定部16が例えば溶接で接合されている。  The diagonal member 12 is supported by the lower part of the main body 13a of the extending member 13 so as to be rotatable about a rotating shaft 13c. The diagonal member 12 includes a latching portion 14 for latching it on the flange 2 of the column 1, a long elongated portion 15, and a fixing portion 16 for fixing the handrail 10 to the flange 2. ing. The latching part 14 is joined to one end of the long part 15 by welding, for example, and the fixing part 16 is joined to the other end of the long part 15 by welding, for example.

掛止部14は、延出部材13の本体13aに枢結された平坦部14aと、平坦部14aの支柱1側の一辺に設けられ、フランジ2の係止孔2bに掛止されるフック14bとを有する。  The hooking portion 14 is provided with a flat portion 14a pivotally connected to the main body 13a of the extending member 13 and a hook 14b provided on one side of the flat portion 14a on the column 1 side and hooked into the locking hole 2b of the flange 2. And have.

平坦部14aには、図2に示すように、フック14bが係止孔2bに掛止されたとき、支柱1側の反対側から右斜め下方向(図2の場合)に延びるようにして長尺部15が接合される。フック14bは、その厚みがフランジ2の係止孔2bの大きさに適合するように平坦部14aより大とされている。  As shown in FIG. 2, when the hook 14b is hooked in the locking hole 2b, the flat portion 14a is extended so as to extend diagonally downward to the right (in the case of FIG. 2) from the opposite side of the column 1 side. The scale portion 15 is joined. The thickness of the hook 14b is larger than that of the flat portion 14a so that the thickness thereof matches the size of the locking hole 2b of the flange 2.

斜材12の長尺部15は、現場作業者の足場板3からの転落を防止する目的で、水平材11の下方であって足場板3との間の開口を可能な限り遮るためのものであり、その長さが水平材11より大とされている。長尺部15は、円筒状のパイプ部15aと、パイプ部15aの両端部が平板状に形成された2つの平板部15bとを有する。  The long portion 15 of the diagonal member 12 is used to block the opening between the scaffolding plate 3 and the lower portion of the horizontal member 11 as much as possible in order to prevent the site worker from falling from the scaffolding plate 3. And its length is larger than that of the horizontal member 11. The long portion 15 includes a cylindrical pipe portion 15a and two flat plate portions 15b in which both end portions of the pipe portion 15a are formed in a flat plate shape.

一方端の平板部15bは、手摺10が折り畳まれた状態で延出部材13の当接片13bに当接される。これにより、斜材12は、水平材11と交差する状態にはならず、手摺10は、折り畳まれたときに略棒状となるようにされる。  The flat plate portion 15b at one end is in contact with the contact piece 13b of the extending member 13 in a state where the handrail 10 is folded. As a result, the diagonal member 12 does not cross the horizontal member 11, and the handrail 10 is substantially rod-shaped when folded.

固定部16は、他方端の平板部15bに設けられている。固定部16は、図4及び図5に示すように、平板部15bに接続された平面視略Z字状のZ字状部材17と、Z字状部材17に固定された断面視略コ字状のコ字状部材18と、長尺状のクサビ19とによって構成されている。固定部16は、フランジ2の係止孔2bに係止されつつ固定される。  The fixing portion 16 is provided on the flat plate portion 15b at the other end. As shown in FIGS. 4 and 5, the fixing portion 16 includes a substantially Z-shaped member 17 having a substantially Z-shape in plan view connected to the flat plate portion 15 b, and a substantially U-shaped sectional view secured to the Z-shaped member 17. The U-shaped member 18 and the long wedge 19 are formed. The fixing portion 16 is fixed while being locked in the locking hole 2 b of the flange 2.

コ字状部材18の平面部分には、クサビ19を挿通するための挿通孔18aが形成されている。この固定部16では、コ字状部材18をフランジ2にかざし、フランジ2の係止孔2b及び挿通孔18aを貫通するようにしてクサビ19を打ち込むことにより、支柱1のフランジ2と固定部16とが固定される。  An insertion hole 18 a for inserting the wedge 19 is formed in the planar portion of the U-shaped member 18. In the fixing portion 16, the U-shaped member 18 is held over the flange 2, and the wedge 19 is driven so as to penetrate the locking hole 2 b and the insertion hole 18 a of the flange 2, whereby the flange 2 and the fixing portion 16 of the column 1 are driven. And are fixed.

次に、手摺10を支柱1に取付けるときの手順について説明する。なお、本実施形態に係る手摺10は、一つ上の層を組み立てる際、一つ上の層の足場板3を敷設する前に先行的に支柱1に取付けるものであり、このような手摺10は「先行手摺」と呼称される。  Next, a procedure for attaching the handrail 10 to the column 1 will be described. In addition, the handrail 10 which concerns on this embodiment attaches to the support | pillar 1 before laying the scaffold board 3 of an upper layer, when assembling the upper layer, such a handrail 10 Is referred to as the "preceding handrail".

まず、例えば図1に示す左側の支柱1のフランジ2の係止孔2bに、水平材11の一方端に設けられた掛止部14のフック14bを嵌挿する。次いで、左側の支柱1と隣り合う右側の支柱1のフランジ2の係止孔2bに、水平材11の他方端に設けられた掛止部14のフック14bを嵌挿する。  First, for example, the hook 14b of the latching portion 14 provided at one end of the horizontal member 11 is inserted into the locking hole 2b of the flange 2 of the left column 1 shown in FIG. Next, the hook 14 b of the latching portion 14 provided at the other end of the horizontal member 11 is inserted into the locking hole 2 b of the flange 2 of the right column 1 adjacent to the left column 1.

次に、左側の支柱1のフランジ2の下方に設けられている他のフランジ2に対して、一方の斜材12の他方端に設けられた固定部16のコ字状部材18をかざす。次いで、クサビ19を他のフランジ2の係止孔2bに上方から嵌挿し、ハンマー等で打ち込むことにより、クサビ19を固定部16に固定する。  Next, the U-shaped member 18 of the fixing portion 16 provided at the other end of one diagonal member 12 is held over the other flange 2 provided below the flange 2 of the left column 1. Next, the wedge 19 is inserted into the locking hole 2 b of the other flange 2 from above and driven by a hammer or the like, thereby fixing the wedge 19 to the fixing portion 16.

その後、右側の支柱1のフランジ2の下方に設けられている他のフランジ2に対して、他方の斜材12の他方端に設けられた固定部16のコ字状部材18をかざす。次いで、クサビ19を他のフランジ2の係止孔2bに上方から嵌挿し、ハンマー等で打ち込むことにより、クサビ19を固定部16に固定する。  Thereafter, the U-shaped member 18 of the fixing portion 16 provided at the other end of the other diagonal member 12 is held over the other flange 2 provided below the flange 2 of the right column 1. Next, the wedge 19 is inserted into the locking hole 2 b of the other flange 2 from above and driven by a hammer or the like, thereby fixing the wedge 19 to the fixing portion 16.

上記のように、手摺10は支柱1に容易に取付けることができる。特に、斜材12は掛止部14と長尺部15とが一体的に設けられているため、現場作業者は、下の層からも長尺部15を自在に取り扱って掛止部14をフランジ2の係止孔2bに容易にかつ確実に嵌挿することができる。なお、手摺10を支柱1から取り外すときの手順は、上記した取付けるときの手順の逆の手順となる。  As described above, the handrail 10 can be easily attached to the column 1. In particular, since the diagonal member 12 is provided with the latching portion 14 and the long portion 15 integrally, the field worker can handle the long portion 15 freely from the lower layer so that the latching portion 14 can be handled. It can be easily and reliably inserted into the locking hole 2b of the flange 2. The procedure for removing the handrail 10 from the column 1 is the reverse of the procedure for attaching the handrail 10 described above.

次に、本実施形態に係る手摺10の作用について説明する。  Next, the operation of the handrail 10 according to the present embodiment will be described.

従来の構成の手摺33では、水平材34に掛止フック35のみ(図8参照)が直接的に設けられており、掛止フック35の回動軸は、掛止フック35が掛止されるフランジ32の高さ位置とほぼ同じ位置に設定されていた。  In the handrail 33 having a conventional configuration, only the latching hook 35 (see FIG. 8) is directly provided on the horizontal member 34, and the pivoting shaft of the latching hook 35 is latched by the latching hook 35. The height of the flange 32 was set at almost the same position.

しかしながら、本実施形態に係る手摺10では、水平材11に対して延出部材13が下方向に延びて設けられており、延出部材13における掛止部14の回動軸13cは、掛止部14が掛止されるフランジ2の高さ位置よりやや上方に位置している。  However, in the handrail 10 according to the present embodiment, the extending member 13 extends downward with respect to the horizontal member 11, and the rotation shaft 13 c of the engaging portion 14 of the extending member 13 is engaged with the engaging member 13. It is located slightly above the height position of the flange 2 where the portion 14 is hooked.

そのため、足場板3の表面から水平材11の上端までの高さH(図1参照)を、ほぼ延出部材13の上下方向の長さ分、従来の構成(図8参照)に比べ高くすることができる。例えば、足場板3の表面と一つ上の層に設けられる他の足場板3の表面同士の間隔が約1900mmの場合、足場板3の表面から水平材11の上端までの高さを、約1900mmの半分以上の例えば約1000mm以上にすることができる。したがって、現場作業者の安心感を高めることができる。  Therefore, the height H (see FIG. 1) from the surface of the scaffold plate 3 to the upper end of the horizontal member 11 is made higher than the conventional configuration (see FIG. 8) by the length of the extending member 13 in the vertical direction. be able to. For example, when the distance between the surface of the scaffolding plate 3 and the surface of the other scaffolding plate 3 provided in the upper layer is about 1900 mm, the height from the surface of the scaffolding plate 3 to the upper end of the horizontal member 11 is about It can be more than half of 1900 mm, for example, about 1000 mm or more. Therefore, it is possible to enhance the sense of security of the field worker.

上記のように、水平材11の下方に延出部材13を設けると、水平材11と斜材12との間が広がることになる。そのため、手摺10が折り畳まれて斜材12が回動されるとき、従来の構成の手摺33のように水平材34と斜材36との隙間が狭い場合に比べ、斜材12が水平材11と交差して斜材12が必要以上に回動することになる。  As described above, when the extending member 13 is provided below the horizontal member 11, the space between the horizontal member 11 and the diagonal member 12 is expanded. Therefore, when the handrail 10 is folded and the diagonal member 12 is rotated, the diagonal member 12 is made of the horizontal member 11 as compared with the case where the gap between the horizontal member 34 and the diagonal member 36 is narrow as in the handrail 33 having the conventional configuration. As a result, the diagonal member 12 rotates more than necessary.

しかしながら、本実施形態では、延出部材13に当接片13bが設けられているため、手摺10が折り畳まれて斜材12が回動されたとしても、図6に示すように、斜材12の平板部15bが延出部材13の当接片13bに当接される。そのため、斜材12が水平材11と交差することがなく、すなわち斜材12は必要以上に回動することがない。それゆえ、手摺10は、図7に示すように、略棒状の状態となり、例えば複数の手摺10を束ねて梱包された状態から一つの手摺10を取り出すとき、手摺10同士が絡み合う可能性を低くすることができる。  However, in this embodiment, since the extending piece 13 is provided with the contact piece 13b, even if the handrail 10 is folded and the diagonal member 12 is rotated, the diagonal member 12 is shown in FIG. The flat plate portion 15 b comes into contact with the contact piece 13 b of the extending member 13. Therefore, the diagonal member 12 does not cross the horizontal member 11, that is, the diagonal member 12 does not rotate more than necessary. Therefore, as shown in FIG. 7, the handrail 10 has a substantially rod-like state. For example, when one handrail 10 is taken out from a state in which a plurality of handrails 10 are bundled and packed, the possibility that the handrails 10 are entangled with each other is reduced. can do.

したがって、従来の構成に比べ、よりスムーズに一つの手摺10を取り出すことができる。また、手摺10を取り出すとき、斜材12と水平材11との間に手を挟んだり、斜材12の一端が広がり過ぎてその端部が他の障害物と衝突して損傷したりすることを抑制することができる。  Therefore, one handrail 10 can be taken out more smoothly than in the conventional configuration. Further, when the handrail 10 is taken out, a hand is sandwiched between the diagonal member 12 and the horizontal member 11, or one end of the diagonal member 12 is excessively widened and the end portion collides with other obstacles and is damaged. Can be suppressed.

また、複数の手摺10を梱包する際にも、一つの手摺10が略棒状となるため、複数の手摺10を整然と並べて梱包することができるので、梱包スペースを極力コンパクトにすることができる。  Also, when packing a plurality of handrails 10, since one handrail 10 has a substantially bar shape, a plurality of handrails 10 can be arranged in an orderly manner, so that the packing space can be made as compact as possible.

なお、本発明の範囲は上述した実施の形態に限定されるものではなく、発明の範囲を逸脱しない範囲で種々の変更を行うことができる。例えば上記実施形態においては、支柱1にフランジ2が設けられている場合にそのフランジ2に対して取付けられる手摺10について説明したが、支柱1には、フランジ2に代えて、中空状のポケットが備えられてもよく、上記手摺10は、このポケットに取付けられる構成とされてもよい。  The scope of the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention. For example, in the above embodiment, the handrail 10 attached to the flange 2 when the flange 1 is provided on the support column 1 has been described. However, the support column 1 has a hollow pocket instead of the flange 2. The handrail 10 may be configured to be attached to the pocket.

また、上記実施形態における手摺10を構成する部材の形状、大きさ、数量等は、上記実施形態に限るものではなく、適宜設計変更可能である。例えば、延出部材13は、本体部13aと当接片13bとが一体的に設けられるのではなく、分離されて設けられていてもよい。また、延出部材13の上下方向の長さは、水平材11の高さ位置に応じて逐次変更されてもよい。  In addition, the shape, size, quantity, and the like of the members constituting the handrail 10 in the above embodiment are not limited to the above embodiment, and can be appropriately changed in design. For example, the extending member 13 may be provided separately from the main body portion 13a and the contact piece 13b instead of being provided integrally. Further, the length of the extending member 13 in the vertical direction may be sequentially changed according to the height position of the horizontal member 11.
