Description

本発明は、建築工事現場等で組立てられる仮設足場、特にくさび緊結式足場において用いられる梁枠の取付構造に関する。 The present invention relates to a beam frame mounting structure used in a temporary scaffold assembled at a construction site or the like, particularly a wedge-tied scaffold.

従来、仮設足場は、建築工事現場において例えばビル等の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や塗装等の工事を行うために用いられる。近年では、仮設足場に用いられる複数種類の仮設部材を連結するためにくさびが用いられる、いわゆるくさび緊結式足場が採用されている(例えば「特許文献1」参照)。 Conventionally, a temporary scaffold is provided at a construction site along a building such as a building, and is used by a site worker to perform work such as repairing or painting the building. In recent years, so-called wedge-tied scaffolds in which wedges are used to connect a plurality of types of temporary members used for temporary scaffolds have been adopted (see, for example, "Patent Document 1").

くさび緊結式足場は、図13に示すように、通常、基本スパン(例えば1829mm)ごとに支柱41が立設され、支柱41に各仮設部材が連結されることにより構築される。くさび緊結式足場がマンションや店舗を有するビルに沿って設けられる場合、マンションや店舗等の出入口に応じて所定の空間を有する開口部Sが形成されることがある(図13参照)。この開口部Sを通じて、マンションや店舗等に人が出入りしたり物を運搬したりすることができる。 As shown in FIG. 13, the wedge-tied scaffold is usually constructed by erection of columns 41 for each basic span (for example, 1829 mm) and connecting each temporary member to the columns 41. When the wedge-tied scaffolding is provided along the building having the condominium or the store, an opening S having a predetermined space may be formed according to the entrance / exit of the condominium or the store (see FIG. 13). Through this opening S, people can go in and out of condominiums, stores, and the like, and things can be transported.

くさび緊結式足場において開口部Sが形成される場合、開口部Sの上方部分にも仮設部材が設けられるため、通常、それらを支持するための梁枠42が取付けられる。梁枠42は、開口部Sの上部であって前踏み側(建築物に近い側)及び後踏み側(建築物に遠い側)の両方に横方向に延びて取付けられる(図13では後踏み側の梁枠42のみを示している。)。 When the opening S is formed in the wedge-tied scaffold, temporary members are also provided in the upper portion of the opening S, so that a beam frame 42 for supporting them is usually attached. The beam frame 42 is the upper part of the opening S and is attached to both the front step side (the side closer to the building) and the rear step side (the side far from the building) extending laterally (rear step in FIG. 13). Only the side beam frame 42 is shown).

梁枠42は、開口部Sの幅とほぼ同じ長さとされ、図14に示すように、2本の水平材43,44が平行に配され、それらが縦材45や斜材46等によって連結されて形成されている。縦材45の上部には、ほぞ47が縦材45に連続するように形成されている。このほぞ47には、開口部Sの上方部分に配置される支柱41が嵌挿されて立設される。 The beam frame 42 has substantially the same length as the width of the opening S, and as shown in FIG. 14, two horizontal members 43 and 44 are arranged in parallel, and they are connected by a vertical member 45, an oblique member 46, or the like. Is formed. A tenon 47 is formed on the upper part of the vertical member 45 so as to be continuous with the vertical member 45. A support column 41 arranged in the upper portion of the opening S is inserted into the tenon 47 and erected.

梁枠42の端部は、図15に示すように、支柱41に設けられたフランジ48に連結される。より詳細には、フランジ48に梁枠42の連結部材49が挟持され、くさび50が連結部材49を貫通しつつ、フランジ48に形成された掛止孔51に緊結されることにより、梁枠42の端部と支柱41とが連結される。 As shown in FIG. 15, the end portion of the beam frame 42 is connected to the flange 48 provided on the support column 41. More specifically, the connecting member 49 of the beam frame 42 is sandwiched between the flange 48, and the wedge 50 penetrates the connecting member 49 and is fastened to the hook hole 51 formed in the flange 48, whereby the beam frame 42 The end portion of the support 41 is connected to the support column 41.

くさび緊結式足場においては、通常、左右方向に隣り合う支柱41の設置間隔W(図13参照)が基本スパンとされ、この基本スパンごとに支柱41が立設される。そのため、開口部Sの幅は、基本スパンが基準となり、すなわち基本スパンの倍数の幅となるように設定される。 In the wedge-tied scaffolding, the installation interval W (see FIG. 13) of the columns 41 adjacent to each other in the left-right direction is usually set as the basic span, and the columns 41 are erected for each of the basic spans. Therefore, the width of the opening S is set so as to be based on the basic span, that is, a width that is a multiple of the basic span.

同様に、開口部Sの上方部分においても支柱41の基本スパンを維持する必要があるため、上記梁枠42には、支柱41の設置間隔と一致する間隔Wで縦材45及びほぞ47が設けられている(図14参照)。 Similarly, since it is necessary to maintain the basic span of the support column 41 also in the upper portion of the opening S, the beam frame 42 is provided with the vertical member 45 and the tenon 47 at an interval W corresponding to the installation interval of the support column 41. (See FIG. 14).

ここで、建築工事現場においては、上記開口部Sの幅を任意の幅に設定したい場合がある。例えば建築物が店舗である場合には、開口部Sの幅を店舗の出入口の幅に合わしたり、あるいは開口部Sを車両が通過する場合には、開口部Sの幅を車両の幅よりやや大の幅に合わしたりする場合がある。 Here, at a construction site, it may be desired to set the width of the opening S to an arbitrary width. For example, when the building is a store, the width of the opening S is adjusted to the width of the entrance / exit of the store, or when the vehicle passes through the opening S, the width of the opening S is slightly smaller than the width of the vehicle. It may fit a large width.

しかしながら、くさび緊結式足場における開口部Sの幅は、上記したように、梁枠42の長さと略一致しており、かつ支柱41の基本スパンの倍数の幅に設定されているため、開口部Sの幅を任意の幅に設定すると、従来の梁枠42を用いることができなくなる。 However, as described above, the width of the opening S in the wedge-tied scaffold is substantially the same as the length of the beam frame 42 and is set to a width that is a multiple of the basic span of the support column 41. If the width of S is set to an arbitrary width, the conventional beam frame 42 cannot be used.

そのため、現場作業者は、基本スパンの倍数以外の幅を有する梁枠を別途準備しなければならず、開口部Sの幅は建築工事現場ごとに異なることが多いので、その異なる幅の開口部Sに応じた梁枠を建築工事現場ごとに準備する必要があるといった煩わしさがあった。また、梁枠の種類が多くなると、それらの管理が煩雑になるといった問題点もあった。 Therefore, the site worker must separately prepare a beam frame having a width other than a multiple of the basic span, and the width of the opening S often differs depending on the construction site. There was a trouble that it was necessary to prepare a beam frame corresponding to S for each construction site. In addition, as the number of types of beam frames increases, there is also a problem that their management becomes complicated.

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、本発明に係る梁枠の取付構造が適用される仮設足場の正面図である。仮設足場は、建築工事現場において例えばビル等の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や塗装等の工事を行うために用いられる。 FIG. 1 is a front view of a temporary scaffold to which the beam frame mounting structure according to the present invention is applied. Temporary scaffolding is provided at a construction site along, for example, a building such as a building, and is used by a site worker to perform work such as repairing or painting the building.

図1に示す仮設足場は、複数種類の仮設部材を連結するためにくさびが用いられる、いわゆるくさび緊結式足場である。くさび緊結式足場は、立設された複数の支柱1、隣り合う支柱1間に設けられ作業者が作業を行うあるいは移動するための足場板2、及び隣り合う支柱1間に設けられ作業者の転落を防止するための手摺3等によって概略構成されている。 The temporary scaffold shown in FIG. 1 is a so-called wedge-tied scaffold in which a wedge is used to connect a plurality of types of temporary members. The wedge-tied scaffolding is provided between a plurality of erected columns 1, adjacent columns 1, scaffolding plates 2 for workers to perform work or move, and between adjacent columns 1 for workers. It is roughly composed of handrails 3 and the like for preventing falls.

このくさび緊結式足場に用いられる支柱1には、上下方向に所定間隔を隔ててフランジ5が設けられている(図2参照)。フランジ5は、水平方向に広がるように略花びら状に形成され、十字方向に4つの掛止孔6が形成されている。くさび緊結式足場においては、図1に示す奥行方向に隣り合う支柱1同士の間に例えば腕木材4が配設される。 The columns 1 used for this wedge-tied scaffold are provided with flanges 5 at predetermined intervals in the vertical direction (see FIG. 2). The flange 5 is formed in a substantially petal shape so as to spread in the horizontal direction, and four hook holes 6 are formed in the cross direction. In the wedge-tied scaffolding, for example, arm timber 4 is arranged between the columns 1 adjacent to each other in the depth direction shown in FIG.

腕木材4は、その両端にくさび7が遊嵌される連結部材8が設けられており、フランジ5に形成された掛止孔6にくさび7が緊結されることにより、支柱1のフランジ5に腕木材4が連結される。なお、通常くさび緊結式足場においては、腕木材4に足場板2が支持されて設けられ、フランジ5の他の掛止孔6に図示しない手摺枠3が連結される。 The arm wood 4 is provided with connecting members 8 to which wedges 7 are loosely fitted at both ends thereof, and the wedges 7 are tightly bound to the hook holes 6 formed in the flanges 5 so that the wedges 7 are attached to the flanges 5 of the support columns 1. The arm timber 4 is connected. In the normal wedge binding type scaffolding, the scaffolding plate 2 is supported and provided on the arm timber 4, and the handrail frame 3 (not shown) is connected to the other hooking holes 6 of the flange 5.

図1に戻り、くさび緊結式足場においては、マンションや店舗等の出入口に応じて所定の空間を有する開口部Sが形成されることがある。開口部Sの上部には、その上方部分に配設される仮設部材を支持するための一対の梁枠11が取付けられている。一対の梁枠11は、開口部Sの上部であって前踏み側(建築物に近い側)及び後踏み側(建築物に遠い側)の両方に水平方向に延びるようにして取付けられる。なお、図1では、後踏み側の梁枠11のみを示している。 Returning to FIG. 1, in the wedge-tied scaffolding, an opening S having a predetermined space may be formed depending on the entrance / exit of a condominium, a store, or the like. A pair of beam frames 11 for supporting a temporary member arranged above the opening S is attached to the upper portion of the opening S. The pair of beam frames 11 are attached to the upper part of the opening S so as to extend horizontally to both the front step side (the side closer to the building) and the rear step side (the side far from the building). Note that FIG. 1 shows only the beam frame 11 on the rear step side.

ここで、開口部Sは、その幅が通常、支柱1間の基本スパン(例えば1829mm)の倍数とほぼ一致するように設定されることが多いが、必要に応じ基本スパンの倍数以外の任意の幅に設定されることがある。本実施形態の梁枠11の取付構造は、そのような開口部Sの幅が基本スパンの倍数以外の任意の幅に設定される場合があっても、設定された開口部Sの幅に容易に対応することができるものである。 Here, the width of the opening S is usually set to substantially match a multiple of the basic span (for example, 1829 mm) between the columns 1, but if necessary, any other than a multiple of the basic span is set. May be set to width. The mounting structure of the beam frame 11 of the present embodiment is easy to set the width of the opening S even if the width of the opening S is set to an arbitrary width other than a multiple of the basic span. It is possible to correspond to.

梁枠11は、少なくとも開口部Sの幅より大の長さとされ、図3に示すように、水平方向に延びて形成されたパイプ状の上側水平材12と、それに並行に配されたパイプ状の下側水平材13と、所定の間隔を隔てて上下方向に並設される複数の縦部材14と、隣り合う縦部材14の間にトラス状に設けられた複数の斜材15とによって概略構成されている。 The beam frame 11 has a length at least larger than the width of the opening S, and as shown in FIG. 3, a pipe-shaped upper horizontal member 12 formed so as to extend in the horizontal direction and a pipe-shaped member arranged in parallel therewith. Outlined by a lower horizontal member 13, a plurality of vertical members 14 arranged side by side in the vertical direction at a predetermined interval, and a plurality of diagonal members 15 provided in a truss shape between adjacent vertical members 14. It is configured.

梁枠11の両端部には、この梁枠11をくさび緊結式足場に取付けるための取付部16がそれぞれ設けられている。取付部16は、図4に示すように、上側水平材12の端部(一部)と、上側水平材12寄りに水平方向に延びた補助水平材17と、上側水平材12と補助水平材17との端部同士を連結する連結材18とによって構成されている。 At both ends of the beam frame 11, attachment portions 16 for attaching the beam frame 11 to the wedge-tied scaffolding are provided. As shown in FIG. 4, the mounting portion 16 includes an end portion (part) of the upper horizontal member 12, an auxiliary horizontal member 17 extending in the horizontal direction toward the upper horizontal member 12, and an upper horizontal member 12 and an auxiliary horizontal member. It is composed of a connecting member 18 that connects the ends of the 17 and the end portions to each other.

なお、図4には示していないが、最も端にある縦部材14と、補助水平材17との間には、後述する梁枠受け部材21が邪魔にならなければ、補強材が斜め方向に配されて設けられていてもよい。また、梁枠11の構成は、上方部分に配設される仮設足場を支持することのできる強度を有するものであれば、図3及び図4に示す形状に限るものではない。 Although not shown in FIG. 4, a reinforcing member is obliquely provided between the vertical member 14 at the end and the auxiliary horizontal member 17 unless the beam frame receiving member 21, which will be described later, interferes with the vertical member 14. It may be arranged and provided. Further, the structure of the beam frame 11 is not limited to the shapes shown in FIGS. 3 and 4 as long as it has a strength capable of supporting the temporary scaffolding arranged in the upper portion.

一対の梁枠11は、くさび緊結式足場に対して二対の梁枠受け部材21によって支持されて取付けられる。各梁枠受け部材21は、それ自体は後述するように支柱1のフランジ5に取付けられて用いられる。 The pair of beam frames 11 are supported and attached to the wedge-tightened scaffold by two pairs of beam frame receiving members 21. Each beam frame receiving member 21 is used by being attached to the flange 5 of the support column 1 as described later.

図5は梁枠受け部材21の斜視図であり、図6は梁枠受け部材21の外形を示し、(a)は正面図、(b)は上面図、(c)は右側面図である。また、図7は梁枠受け部材21の背面図である。梁枠受け部材21は、左右方向に並設され梁枠11を支持するための一対のU字状部材22を備えている。一対のU字状部材22は、梁枠11を支持するために、曲面部が下方に位置するように形成されている。一対のU字状部材22には、それらの一方側面の上部及び下部に、それら同士を連結するための平板状の上連結部材23及び下連結部材24がそれぞれ設けられている。 5A and 5B are perspective views of the beam frame receiving member 21, FIG. 6 shows an outer shape of the beam frame receiving member 21, FIG. 5A is a front view, FIG. 5B is a top view, and FIG. 6C is a right side view. .. Further, FIG. 7 is a rear view of the beam frame receiving member 21. The beam frame receiving member 21 is provided side by side in the left-right direction and includes a pair of U-shaped members 22 for supporting the beam frame 11. The pair of U-shaped members 22 are formed so that the curved surface portion is located downward in order to support the beam frame 11. The pair of U-shaped members 22 are provided with a flat upper connecting member 23 and a lower connecting member 24 for connecting them to each other at the upper and lower portions of one side surface thereof.

上連結部材23の背面側には、上下方向に延びた差込片25が設けられている。差込片25は、梁枠受け部材21の取付時に、開口部Sの上部隅部C(図1参照)に位置するフランジ5の掛止孔6に差込まれる。より具体的には、差込片15は、フランジ5において腕木材4が取付けられる掛止孔6と反対側にある掛止孔6(図2参照)に差し込まれる。一方、下連結部材24の背面側には、平板状の取付部材26を介してクランプ27が例えばボルト止めされている。クランプ27は、梁枠受け部材21を支柱1に固定するためのものであり、梁枠受け部材21の取付時に、支柱1を所定の締付けトルクで締め付ける。 An insertion piece 25 extending in the vertical direction is provided on the back surface side of the upper connecting member 23. The insertion piece 25 is inserted into the hook hole 6 of the flange 5 located at the upper corner C (see FIG. 1) of the opening S when the beam frame receiving member 21 is attached. More specifically, the insertion piece 15 is inserted into the hook hole 6 (see FIG. 2) on the flange 5 opposite to the hook hole 6 to which the arm timber 4 is mounted. On the other hand, on the back side of the lower connecting member 24, a clamp 27 is bolted, for example, via a flat plate-shaped mounting member 26. The clamp 27 is for fixing the beam frame receiving member 21 to the support column 1, and when the beam frame receiving member 21 is attached, the support column 1 is tightened with a predetermined tightening torque.

上記U字状部材22のそれぞれには、対向する面の同一高さ位置において貫通孔28が形成されている。一対のU字状部材22には、それらの貫通孔28を貫通するとともに上記一対のU字状部材22を掛け渡すようにコの字状ボルト29が取付けられている。コの字状ボルト29の端部には、蝶ナット30が螺着されている。蝶ナット30は、一対のU字状部材22に梁枠11の上側水平材12及び補助水平材17を配したときに、それらを締付けて固定するためのものである。 Through holes 28 are formed in each of the U-shaped members 22 at the same height positions on the facing surfaces. A U-shaped bolt 29 is attached to the pair of U-shaped members 22 so as to penetrate the through holes 28 and to hang the pair of U-shaped members 22. A wing nut 30 is screwed to the end of the U-shaped bolt 29. The wing nut 30 is for tightening and fixing the upper horizontal member 12 and the auxiliary horizontal member 17 of the beam frame 11 to the pair of U-shaped members 22.

前踏み側及び後踏み側のそれぞれに取付けられた一対の梁枠11同士の間(図1の奥行き方向における間)には、1または複数の梁枠渡し部材31が掛け渡される。梁枠渡し部材31は、後述するように梁枠11の上側水平材12の所定位置に配置される。図1では、3つの梁枠渡し部材31が配置されている。 One or a plurality of beam frame passing members 31 are hung between the pair of beam frames 11 attached to each of the front step side and the rear step side (between in the depth direction of FIG. 1). The beam frame passing member 31 is arranged at a predetermined position on the upper horizontal member 12 of the beam frame 11 as described later. In FIG. 1, three beam frame passing members 31 are arranged.

梁枠渡し部材31は、図8に示すように、長尺状の腕木材4と、その両端に連結される支柱受け部材32とからなる。腕木材4は、パイプ状の本体4aと、本体4aの両端に設けられた連結部材8及びくさび7からなる。なお、本実施形態における梁枠渡し部材31の腕木材4は、本梁枠渡し部材31用に新たに設計製作されたものではなく、図2に示したように、くさび緊結式足場において汎用的に用いられる腕木材4が使用されている。 As shown in FIG. 8, the beam frame passing member 31 includes a long arm timber 4 and a strut receiving member 32 connected to both ends thereof. The arm wood 4 is composed of a pipe-shaped main body 4a, connecting members 8 provided at both ends of the main body 4a, and a wedge 7. The arm timber 4 of the beam frame connecting member 31 in the present embodiment is not newly designed and manufactured for the main beam frame connecting member 31, and is versatile in the wedge binding type scaffolding as shown in FIG. The arm wood 4 used in the above is used.

図9は支柱受け部材32の斜視図であり、図10は支柱受け部材32の外形を示し、(a)は正面図、(b)は上面図、(c)は右側面図である。 9 is a perspective view of the support support member 32, FIG. 10 shows the outer shape of the support support member 32, (a) is a front view, (b) is a top view, and (c) is a right side view.

支柱受け部材32は、円筒状の円筒部33を備え、円筒部33の上部には、その直径よりやや小の直径を有しかつ所定の長さを有するほぞ34が設けられている。ほぞ34は、支柱1が嵌挿されることにより支柱1を立設させるためのものである。円筒部33の周面には、水平方向に広がるように形成され3つの掛止孔35を有するフランジ36が設けられている。また、円筒部33の周面の一部には、平面視略コの字状の連結部37を介して梁枠11に掛止するための側面視U字状のフック部38が設けられている。フック部38は、梁枠11に掛止するために、曲面部が上方に位置するように形成されている。 The strut receiving member 32 includes a cylindrical cylindrical portion 33, and a tenon 34 having a diameter slightly smaller than the diameter and a predetermined length is provided on the upper portion of the cylindrical portion 33. The tenon 34 is for erecting the support column 1 by inserting the support column 1. A flange 36 having three hook holes 35, which is formed so as to spread in the horizontal direction, is provided on the peripheral surface of the cylindrical portion 33. Further, a U-shaped hook portion 38 in a side view for hooking to the beam frame 11 via a connecting portion 37 having a substantially U-shape in a plan view is provided on a part of the peripheral surface of the cylindrical portion 33. There is. The hook portion 38 is formed so that the curved surface portion is located upward in order to hook the hook portion 38 to the beam frame 11.

支柱受け部材32のフランジ36において、フック部38とは反対側に形成された掛止孔35に、腕木材4の連結部材8及びくさび7が連結されることにより、支柱受け部材32と腕木材4とが一体化される。また、腕木材4の他方端の連結部材8及びくさび7にも、他の支柱受け部材32が連結されて一体化される。 In the flange 36 of the strut receiving member 32, the strut receiving member 32 and the arm timber are connected by connecting the connecting member 8 and the wedge 7 of the arm timber 4 to the hook hole 35 formed on the side opposite to the hook portion 38. 4 is integrated. Further, another support support member 32 is also connected and integrated with the connecting member 8 and the wedge 7 at the other end of the arm wood 4.

次に、梁枠11のくさび緊結式足場に対する取付手順について説明する。 Next, the procedure for attaching the beam frame 11 to the wedge-tightened scaffolding will be described.

くさび緊結式足場において開口部Sが形成される場合、開口部Sの上方部分に配設される足場部材を支持するために、一旦、開口部Sが形成される領域に、仮設部材(支柱1、手摺材3及び腕木材4等)による仮足場が仮組みされる。 When the opening S is formed in the wedge-tied scaffold, a temporary member (post 1) is temporarily formed in the region where the opening S is formed in order to support the scaffold member disposed above the opening S. , Handrail material 3 and arm wood 4 etc.) are temporarily assembled.

次に、仮組みされた仮足場の上方に、梁枠受け部材21が取付けられる。より詳細には、梁枠受け部材21は、開口部Sの上部隅部C(図1参照)の両方に位置するフランジ5にそれぞれ取付けられる。すなわち、梁枠受け部材21の差込片25が当該フランジ5の掛止孔6に差し込まれ、クランプ27によってそのフランジ5を有する支柱1が所定の締付けトルクで締め付けられる。これにより、梁枠受け部材21は、開口部Sの上部隅部Cにおいて支柱1に固定される。なお、梁枠受け部材21は、前踏み側及び後踏み側の上部隅部Cに合計4つ取付けられる。 Next, the beam frame receiving member 21 is attached above the temporarily assembled temporary scaffold. More specifically, the beam frame receiving member 21 is attached to each of the flanges 5 located at both the upper corners C (see FIG. 1) of the opening S. That is, the insertion piece 25 of the beam frame receiving member 21 is inserted into the hooking hole 6 of the flange 5, and the support column 1 having the flange 5 is tightened by the clamp 27 with a predetermined tightening torque. As a result, the beam frame receiving member 21 is fixed to the support column 1 at the upper corner C of the opening S. A total of four beam frame receiving members 21 are attached to the upper corners C on the front step side and the rear step side.

次いで、図11に示すように、支柱1に対して固定された梁枠受け部材21に、梁枠11が支持される。詳細には、一対のU字状部材22の内側に梁枠11の取付部16の上側水平材12及び補助水平材17が配置され、コの字状ボルト29が一対のU字状部材22の貫通孔28に挿入されて蝶ナット30で締め付けられることにより、梁枠11の取付部16は、梁枠受け部材21に固定される。 Next, as shown in FIG. 11, the beam frame 11 is supported by the beam frame receiving member 21 fixed to the support column 1. Specifically, the upper horizontal member 12 and the auxiliary horizontal member 17 of the mounting portion 16 of the beam frame 11 are arranged inside the pair of U-shaped members 22, and the U-shaped bolts 29 are the pair of U-shaped members 22. The attachment portion 16 of the beam frame 11 is fixed to the beam frame receiving member 21 by being inserted into the through hole 28 and tightened by the wing nut 30.

梁枠渡し部材31は、図12に示すように、梁枠11の上側水平材12の所定位置(支柱1が立設される位置)に配置される。すなわち、両支柱受け部材32の各フック部38は、前踏み側及び後踏み側の各梁枠11の上側水平材12に、梁枠渡し部材31が掛け渡されるようにして掛止される。 As shown in FIG. 12, the beam frame passing member 31 is arranged at a predetermined position (position where the support column 1 is erected) of the upper horizontal member 12 of the beam frame 11. That is, each hook portion 38 of both strut receiving members 32 is hooked so that the beam frame passing member 31 is hung on the upper horizontal member 12 of each beam frame 11 on the front step side and the rear step side.

次に、各支柱受け部材32のほぞ34に、支柱1がそれぞれ嵌挿される。そして、図12には示していないが、隣り合う梁枠渡し部材31の手摺材4同士の間には、それらを掛け渡すように足場板2が配置される。また、左右方向に隣り合う支柱1の間には、手摺3が取付けられる。その後、開口部Sの領域に仮組みされた仮足場を解体する。これにより、開口部Sの空間が形成される。 Next, the support column 1 is fitted and inserted into the tenon 34 of each support column receiving member 32. Although not shown in FIG. 12, the scaffolding plate 2 is arranged between the handrail members 4 of the adjacent beam frame passing members 31 so as to hang them. Further, a handrail 3 is attached between the columns 1 adjacent to each other in the left-right direction. After that, the temporary scaffold temporarily assembled in the region of the opening S is disassembled. As a result, the space of the opening S is formed.

このように、梁枠11は、梁枠受け部材21によって容易に開口部Sの上部に取付けることができる。梁枠渡し部材31は、梁枠11の上側水平材12の所定位置に掛け渡すことができるので、開口部Sの上方部分に設置される支柱1を好適な位置に立設させることができる。開口部Sの幅は支柱1の配置位置で設定することができるので、開口部Sの幅を基本スパンの倍数以外の幅に設定することができ、すなわち開口部Sの幅を任意の幅に設定することができる。 In this way, the beam frame 11 can be easily attached to the upper part of the opening S by the beam frame receiving member 21. Since the beam frame passing member 31 can be hung at a predetermined position on the upper horizontal member 12 of the beam frame 11, the support column 1 installed in the upper portion of the opening S can be erected at a suitable position. Since the width of the opening S can be set at the arrangement position of the support column 1, the width of the opening S can be set to a width other than a multiple of the basic span, that is, the width of the opening S can be set to an arbitrary width. Can be set.

また、本実施形態によれば、梁枠11は少なくとも開口部Sの幅より大であればよく、梁枠受け部材21によって支持されるので、建築工事現場ごとに開口部Sの幅が異なる場合であっても、建築工事現場ごとに異なる長さの梁枠を準備する必要はない。また、それらを管理する必要もない。また、梁枠21は、その長さが開口部Sの幅より大であればよいので、従来の梁枠42のように寸法精度を必要としない。そのため、梁枠11を容易に製作することができる。 Further, according to the present embodiment, the beam frame 11 may be at least wider than the width of the opening S and is supported by the beam frame receiving member 21, so that the width of the opening S differs depending on the construction site. Even so, it is not necessary to prepare beam frames of different lengths for each construction site. Nor is it necessary to manage them. Further, since the length of the beam frame 21 may be larger than the width of the opening S, the beam frame 21 does not require dimensional accuracy unlike the conventional beam frame 42. Therefore, the beam frame 11 can be easily manufactured.

また、梁枠11は、平面視でくさび緊結式足場の各支柱1の軸心を結ぶ線に対して、外れた位置に取付けられる。具体的には、前踏み側の梁枠11は、梁枠受け部材21によって各支柱1の軸心を結ぶ線からより建築物側に配置され、後踏み側の梁枠11は、各支柱1の軸心を結ぶ線からより建築物から遠ざかる位置に配置される。従来の梁枠42は、支柱1の軸心を結ぶ線と同一線上に配置され、かつ梁枠42の長さと開口部Sの幅がほぼ同じであったことにより、梁枠42の取付け時の作業がしづらいことがあった。しかしながら、本実施形態では、梁枠11は、各支柱1の軸心を結ぶ線から外れた位置に取付けられるので、取付け時の作業性を向上させることができる。 Further, the beam frame 11 is attached at a position deviated from the line connecting the axes of the respective columns 1 of the wedge-tied scaffold in a plan view. Specifically, the beam frame 11 on the front step side is arranged closer to the building from the line connecting the axial centers of the columns 1 by the beam frame receiving member 21, and the beam frame 11 on the rear step side is arranged on each column 1. It is placed at a position farther from the building from the line connecting the axes of. The conventional beam frame 42 is arranged on the same line as the line connecting the axial centers of the columns 1, and the length of the beam frame 42 and the width of the opening S are substantially the same. Sometimes it was difficult to work. However, in the present embodiment, since the beam frame 11 is attached at a position deviated from the line connecting the axial centers of the respective columns 1, the workability at the time of attachment can be improved.

また、本実施形態の支柱受け部材32は、上述したように汎用性のある腕木材4が用いられているので、製作コストを低減することができる。また、汎用性のある腕木材4を用いることから、例えばくさび緊結式足場の奥行き方向の幅が建築工事現場において急遽変更になっても、腕木材4のみを取り換えればよく、柔軟に対応することができる。 Further, since the support member 32 of the present embodiment uses the versatile arm wood 4 as described above, the manufacturing cost can be reduced. Further, since the versatile arm timber 4 is used, for example, even if the width of the wedge-tied scaffold in the depth direction is suddenly changed at the construction site, only the arm timber 4 needs to be replaced, and it can be flexibly dealt with. be able to.

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、上記実施形態における梁枠11、梁枠受け部材21、梁枠渡し部材31、支柱受け部材32等の形状、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、上記実施形態では、支柱1にフランジ5が設けられていたが、フランジ5に代えて例えば上面視コの字状のポケット体が設けられ、各仮設部材はこのポケット体に連結されてもよい。 The scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention. For example, the shapes, sizes, quantities, etc. of the beam frame 11, the beam frame receiving member 21, the beam frame passing member 31, the strut receiving member 32, etc. in the above embodiment are not limited to the above embodiment, and the design can be changed as appropriate. Is. For example, in the above embodiment, the flange 5 is provided on the support column 1, but instead of the flange 5, for example, a U-shaped pocket body in a top view is provided, and each temporary member may be connected to the pocket body.
