In addition, the front and back of the wire fixture 20 are defined as the back surface facing the steel frame pillar 1 when the wire fixture 20 is fixed to the steel frame 1, and the front is the surface opposite to the steel frame pillar 1. Suppose there is. Also, the outside and the inside are determined with the steel column 1 as a reference. That is, the direction approaching the center of the steel frame column 1 is defined as the inward direction, and the direction away from the center is defined as the outward direction.

［１．柱吊治具１０の構成について］
図１に、柱である鉄骨柱１と、鉄骨柱１を懸吊するために取り付けられた柱吊治具１０とを示す。柱吊治具１０は、建物の躯体に使用される鉄骨柱１を、横倒しに仮置きした状態から、吊り上げ装置により建て起こし、吊り上げて所望の場所まで移動させた後、立設させた状態で固定するために用いられる。 [1. Regarding the configuration of the pillar hanging jig 10]
FIG. 1 shows a steel frame column 1 as a column and a column hanging jig 10 attached to suspend the steel frame column 1 . The column lifting jig 10 is used to temporarily place a steel frame column 1 used for a frame of a building sideways, erect it by a lifting device, lift it up, move it to a desired place, and then set it upright. Used for fixation.

柱吊治具１０は、吊り上げ装置、例えばクレーン（図示しない）に連結され、柱である鉄骨柱１を建て起こすものである。柱吊治具１０は、ヘッド部材１２（図２Ａ及び図２Ｂ）と、一対のワイヤ固定具２０（図３乃至図６）とを備える。 The column lifting jig 10 is connected to a lifting device such as a crane (not shown) to erect the steel column 1 as a column. The post hanging jig 10 includes a head member 12 (FIGS. 2A and 2B) and a pair of wire fixtures 20 (FIGS. 3 to 6).

柱吊治具１０により建て起こす鉄骨柱１は、図１及び図３に示すように断面矩形の鉄骨柱１であり、柱頭部１ａに付属物としてのガセットプレート１ｂが設けられている。また、鉄骨柱１の側面には、足場として仮設される作業床を設置するためにも用いられる係合部２が取り付けられている。係合部２は、図１、図３及び図４Ａに示すように屈曲した板状部材を折り曲げることにより形成され、溶接等により、鉄骨柱１の側面に取り付けることにより構成される。 As shown in FIGS. 1 and 3, the steel frame column 1 erected by the column suspension jig 10 is a steel frame column 1 having a rectangular cross section, and a gusset plate 1b is provided as an accessory on the column head 1a. In addition, on the side surface of the steel column 1, an engaging portion 2 is attached which is also used for installing a work floor that is temporarily provided as a scaffolding. The engaging portion 2 is formed by bending a bent plate-like member as shown in FIGS.

鉄骨柱１の外周面と係合部２との間には、折り曲げることにより形成された上下方向に延びる隙間が２か所形成されおり、上下の端部に開口部２ａ，２ｂがそれぞれ二つずつ形成されている。なお、作業床（図示しない）を設置する際は、係合部２の上側の開口部２ａに作業床に形成された係止爪を挿入して、作業床を固定する。係合部２は、図１に示すようにいくつかの高さで作業床を設置することができるよう、鉄骨柱１の各側面において上下方向に、所定の間隔にて設けられている。 Between the outer peripheral surface of the steel frame column 1 and the engaging portion 2, two vertically extending gaps formed by bending are formed, and two openings 2a and 2b are formed at the upper and lower ends, respectively. formed one by one. When installing a work floor (not shown), the work floor is fixed by inserting a locking claw formed on the work floor into the opening 2a on the upper side of the engaging portion 2. As shown in FIG. The engaging portions 2 are provided at predetermined intervals in the vertical direction on each side surface of the steel column 1 so that work floors can be installed at several heights as shown in FIG.

作業床を設置するための係合部２が溶接されていることにより、従来、鉄骨柱１の側面に作業床や梯子を取りつけるために形成された孔を設ける必要がなくなる。また、鉄骨柱１に孔を形成する作業には手間がかかることから、鉄骨柱１を吊り上げて移動するために、予め設けられた鉄骨柱１の係合部２を用いることが望ましい。また、鉄骨柱１に孔が形成されないため、孔を形成した場合と比較してより高い強度を得ることができ好適である。 Since the engagement part 2 for installing the working floor is welded, there is no need to form holes for attaching the working floor and the ladder to the side surface of the steel frame column 1 conventionally. Further, since the work of forming a hole in the steel column 1 is time-consuming, it is desirable to use the previously provided engagement portion 2 of the steel column 1 in order to lift and move the steel column 1 . Moreover, since no holes are formed in the steel frame column 1, it is possible to obtain higher strength than in the case where holes are formed, which is preferable.

鉄骨柱１の下端には、基礎３２に固定するための柱プレート３０が設けられている。柱プレート３０の四隅には、鉄骨柱１を基礎３２に固定するアンカーボルト３３（図８Ｄ参照）を通す貫通孔３０ａが形成されている。 A column plate 30 for fixing to a foundation 32 is provided at the lower end of the steel frame column 1 . At the four corners of the column plate 30, through holes 30a are formed through which anchor bolts 33 (see FIG. 8D) that fix the steel column 1 to the foundation 32 are passed.

＜ヘッド部材１２＞
図２Ａ及び図２Ｂに示されるように、本実施形態の柱吊治具１０が備えるヘッド部材１２は枠状の部材であり、本実施形態では図１に示すように鉄骨柱１の上端の柱頭部１ａを囲むように配置され、クレーンから延びる２本のワイヤ１４（連結部材）と連結する。後述するように、一対のワイヤ固定具２０は、ヘッド部材１２より下方に配置され、ヘッド部材１２から延びる２本のワイヤ１５（連結部材）のそれぞれと連結する。なお、連結部材としてのワイヤ１４，１５は、スリングやチェーンなど、他の連結部材であってもよい。 <Head member 12>
As shown in FIGS. 2A and 2B, the head member 12 included in the column suspension jig 10 of this embodiment is a frame-shaped member. In this embodiment, as shown in FIG. It is arranged so as to surround the portion 1a and is connected with two wires 14 (connecting members) extending from the crane. As will be described later, the pair of wire fixtures 20 are arranged below the head member 12 and are connected to two wires 15 (connecting members) extending from the head member 12 . The wires 14 and 15 as connecting members may be other connecting members such as slings and chains.

ワイヤ１５の長さＬは、鉄骨柱１を建て起こしたとき、ヘッド部材１２が、鉄骨柱１の柱頭部１ａ（上端部）から外れない長さに設定されている。言い換えれば鉄骨柱１を立設させたときのワイヤ１５の上端の位置は、鉄骨柱１の高さＨよりも低くなるように設定されている。なお、ワイヤ１５は中間部分に不図示のターンバックルが設けられており、長さ調整可能になっている。 The length L of the wire 15 is set so that the head member 12 does not come off the stigma 1a (upper end) of the steel column 1 when the steel column 1 is erected. In other words, the position of the upper end of the wire 15 when the steel column 1 is erected is set to be lower than the height H of the steel column 1 . The wire 15 is provided with a turnbuckle (not shown) at its intermediate portion so that the length of the wire 15 can be adjusted.

ヘッド部材１２の上方にはストッパ１３を設けられている。ストッパ１３は、クレーンから延びるワイヤ１４が外れたとき下方にヘッド部材１２が落下することを防止する。また、ヘッド部材１２の側面１２ｂには、ワイヤ１４の端部に設けられたフック１８と、ワイヤ１５の端部に設けられたフック１７とを掛けるためのフック掛け１２ａが設けられている。 A stopper 13 is provided above the head member 12 . The stopper 13 prevents the head member 12 from falling downward when the wire 14 extending from the crane comes off. A side surface 12b of the head member 12 is provided with a hook hook 12a for hooking a hook 18 provided at the end of the wire 14 and a hook 17 provided at the end of the wire 15. As shown in FIG.

（スリット１２ｃ）
枠状のヘッド部材１２の４つの側面１２ｂ（より詳細には、側面１２ｂの中央）にはそれぞれ、ヘッド部材１２の下端から上方に向かって延在する受容部としてのスリット１２ｃが形成されている。このスリット１２ｃは、鉄骨柱１の柱頭部１ａに設けられた付属物としてのガセットプレート１ｂを受容可能である。スリット１２ｃの長さは、鉄骨柱１の延在方向（つまり上下方向）におけるガセットプレート１ｂの長さの１／２以上となるように形成されている。 (Slit 12c)
Four side faces 12b (more specifically, the center of the side faces 12b) of the frame-shaped head member 12 are formed with slits 12c as receiving portions extending upward from the lower end of the head member 12. . This slit 12c can receive a gusset plate 1b as an attachment provided on the stigma 1a of the steel column 1. As shown in FIG. The length of the slit 12c is formed to be 1/2 or more of the length of the gusset plate 1b in the extending direction of the steel frame column 1 (that is, the vertical direction).

ガセットプレート１ｂなどの付属物は、鉄骨柱１の４つの側面に配置される可能性があるが、本実施形態に係る柱吊治具１０が備えるヘッド部材１２は、４つの側面１２ｂにそれぞれ、スリット１２ｃが形成されているため、鉄骨柱１の柱頭部１ａに配置される付属物の数、付属物が配置される側面の組み合わせが異なる場合にも対応することが可能である。 Attachments such as the gusset plate 1b may be arranged on the four side surfaces of the steel frame column 1, but the head member 12 included in the column suspension jig 10 according to the present embodiment is provided on the four side surfaces 12b. Since the slits 12c are formed, it is possible to cope with cases where the number of attachments arranged on the stigma 1a of the steel frame column 1 and the combination of the side surfaces on which the attachments are arranged are different.

本実施形態に係る柱吊治具１０は、枠状のヘッド部材１２が、鉄骨柱１の柱頭部１ａを囲いつつ、付属物であるガセットプレート１ｂをスリット１２ｃに受容可能である。つまり、柱頭部１ａに付属物を備える鉄骨柱１であっても、スリット１２ｃを備えるヘッド部材１２により柱頭部１ａを確実に保持して建て起こして懸吊することが可能となる。 In the column suspension jig 10 according to the present embodiment, the frame-shaped head member 12 surrounds the column head portion 1a of the steel frame column 1, and the gusset plate 1b as an attachment can be received in the slit 12c. That is, even if the steel frame column 1 has an appendage on the stigma 1a, the head member 12 having the slit 12c can reliably hold the stigma 1a and erect and suspend it.

また、図１及び図２Ａに示されるように、スリット１２ｃは、鉄骨柱１の延在方向（つまり上下方向）におけるガセットプレート１ｂの長さよりも長く形成されている。この構成によれば、ヘッド部材１２が鉄骨柱１の柱頭部１ａを囲んだ状態で、鉄骨柱１の延在方向においてガセットプレート１ｂがスリット１２ｃ内に安定して受容されるため、鉄骨柱１の柱頭部１ａをより確実に保持しつつ、鉄骨柱１を建て起こして懸吊することが可能となる。 Further, as shown in FIGS. 1 and 2A, the slit 12c is formed longer than the length of the gusset plate 1b in the extending direction of the steel frame column 1 (that is, the vertical direction). According to this configuration, the gusset plate 1b is stably received in the slit 12c in the extending direction of the steel frame column 1 in a state where the head member 12 surrounds the stigma portion 1a of the steel frame column 1. It is possible to erect and suspend the steel frame column 1 while more securely holding the column head 1a.

また、図２Ｂに示されるように、ヘッド部材１２の側面１２ｂにおいて、フック１７，１８を介してワイヤ１４，１５が連結される連結部としてのフック掛け１２ａが、ヘッド部材１２の上面視において点対称となるに配置されている。より詳細には、上面視において、ヘッド部材１２の対向する側面１２ｂにおいて中央に形成された各スリット１２ｃに対して、反対側にフック掛け１２ａが配置されている。 Also, as shown in FIG. 2B, on the side surface 12b of the head member 12, the hook hook 12a as a connecting portion to which the wires 14 and 15 are connected via the hooks 17 and 18 is a point when the head member 12 is viewed from above. are arranged symmetrically. More specifically, hook hooks 12a are arranged on opposite sides of slits 12c formed in the center of opposing side surfaces 12b of the head member 12 when viewed from above.

このようなフック掛け１２ａの配置によれば、ヘッド部材１２のスリット１２ｃ内に付属物を受容しつつ、バランスよく適切にワイヤ１４，１５をフック掛け１２ａに対して連結することが可能となる。 By arranging the hooks 12a in this way, it is possible to receive the attachments in the slits 12c of the head member 12 and to properly connect the wires 14 and 15 to the hooks 12a in a well-balanced manner.

また、スリット１２ｃは、ガセットプレート１ｂの厚みよりも幅が広く、ガセットプレート１ｂの上下方向の長さよりも長く（深く）なるように形成されているため、仮にヘッド部材１２が傾いた場合や、鉄骨柱１が回転した場合であっても、スリット１２ｃからガセットプレート１ｂが抜けることなく、ヘッド部材１２によって、鉄骨柱１の柱頭部１ａが安定して保持される。 Further, since the slit 12c is formed to be wider than the thickness of the gusset plate 1b and longer (deeper) than the vertical length of the gusset plate 1b, even if the head member 12 is tilted or Even when the steel column 1 rotates, the head member 12 stably holds the column head 1a of the steel column 1 without the gusset plate 1b coming off from the slit 12c.

＜ワイヤ固定具２０＞
本実施形態の柱吊治具１０が備える一対のワイヤ固定具２０（固定具）は、鉄骨柱１の側面に取り付けられ、互いに反対方向に位置する係合部２に着脱可能に固定される。ワイヤ固定具２０は、上述したように、鉄骨柱１の側部に設けられた係合部２に着脱可能に固定される治具であり、図３乃至図７に示すように、ヘッド部材１２から延びるワイヤ１５に連結する基部２１を有する。基部２１は、矩形の板状に形成された金属製の部材であり、両端部から下方に延びる側部２２が設けられている。 <Wire fixture 20>
A pair of wire fixtures 20 (fixtures) included in the pole hanging jig 10 of the present embodiment are attached to the side surface of the steel frame column 1 and detachably fixed to the engaging portions 2 located in opposite directions. As described above, the wire fixture 20 is a jig detachably fixed to the engaging portion 2 provided on the side of the steel frame column 1. As shown in FIGS. It has a base 21 that connects to a wire 15 extending from. The base portion 21 is a rectangular plate-shaped metal member, and is provided with side portions 22 extending downward from both ends thereof.

また、ワイヤ固定具２０は、側部２２により基部２１と所定距離離れた位置に設けられた第一係止部２３を有する。第一係止部２３の上端には、係合部２の下側端部の開口部２ｂに挿入される第一係止片２３ａが形成されている。 The wire fixture 20 also has a first locking portion 23 provided at a position separated from the base portion 21 by a predetermined distance from the side portion 22 . The upper end of the first locking portion 23 is formed with a first locking piece 23 a that is inserted into the opening 2 b at the lower end of the engaging portion 2 .

ワイヤ固定具２０は、操作部材２５及び支持部材２６を有している。また、操作部材２５及び支持部材２６の下端には、第二係止部２４が接続されている。第二係止部２４は後述する操作部材２５及び支持部材２６と接続されており、基部２１に対して上下方向に移動可能である。ワイヤ固定具２０を係合部２に対して取り付けるときに、操作部材２５を操作（回転操作）することで、第二係止部２４を基部２１から係合部２に向けて、下方（図５の矢印Ｂ方向）に移動させる。また、第二係止部２４は、係合部２の上側端部の開口部２ａに挿入される第二係止片２４ａが下端に形成されている。 The wire fixture 20 has an operation member 25 and a support member 26 . A second locking portion 24 is connected to the lower ends of the operating member 25 and the supporting member 26 . The second locking portion 24 is connected to an operation member 25 and a support member 26 which will be described later, and is vertically movable with respect to the base portion 21 . When the wire fixture 20 is attached to the engaging portion 2, by operating (rotating) the operating member 25, the second locking portion 24 is downwardly (see FIG. 5 in the direction of arrow B). A second locking piece 24a is formed at the lower end of the second locking portion 24. The second locking piece 24a is inserted into the opening 2a at the upper end of the engaging portion 2. As shown in FIG.

図５に示されるように、上側の第二係止片２４ａの上下方向の長さよりも、下側の第一係止片２３ａの上下方向の長さが長く形成されている。係合部２に対して下側から挿入される第一係止片２３ａが長く形成されているため、第一係止片２３ａが係合部２の下側端部の開口部２ｂから外れ難くなるので、鉄骨柱１の係合部２に対するワイヤ固定具２０の取り付け状態が安定する。 As shown in FIG. 5, the vertical length of the lower first locking piece 23a is longer than the vertical length of the upper second locking piece 24a. Since the first locking piece 23a that is inserted into the engaging portion 2 from below is formed to be long, the first locking piece 23a is difficult to come off from the opening 2b at the lower end of the engaging portion 2. Therefore, the attachment state of the wire fixture 20 to the engaging portion 2 of the steel frame column 1 is stabilized.

操作部材２５は、図３乃至図７に示すように、上端の操作頭部２５ａと、操作頭部２５ａに接続され、ネジ部２５ｂ１及び非ネジ部２５ｂ２が形成された操作軸部２５ｂ（ネジ付軸部材）と、操作部材２５の下端に取り付けられたナット２５ｃと、を有している。ワイヤ固定具２０の基部２１には、上下方向に貫通したネジ孔２１ａが形成されており、このネジ孔２１ａに操作部材２５の操作軸部２５ｂに形成されたネジ部２５ｂ１が螺合している。また、操作部材２５の下端側は、ナット２５ｃが取り付けられており、第二係止部２４に対して回転自在に保持されている。そして、操作頭部２５ａが回転されることで第二係止片２４ａが上下方向に移動する。 As shown in FIGS. 3 to 7, the operation member 25 includes an operation head portion 25a at the upper end and an operation shaft portion 25b (threaded portion) which is connected to the operation head portion 25a and has a threaded portion 25b1 and a non-threaded portion 25b2. and a nut 25 c attached to the lower end of the operating member 25 . The base portion 21 of the wire fixture 20 is formed with a screw hole 21a penetrating in the vertical direction, and a screw portion 25b1 formed on the operation shaft portion 25b of the operation member 25 is screwed into the screw hole 21a. . A nut 25c is attached to the lower end side of the operating member 25, and is rotatably held with respect to the second locking portion 24. As shown in FIG. As the operating head 25a is rotated, the second locking piece 24a moves vertically.

操作軸部２５ｂは、図４Ｂに示されるように、上側から順に、操作頭部２５ａ、ネジ部２５ｂ１（ネジ切りされており、ネジ溝が形成されている部分）、非ネジ部２５ｂ２（ネジ切りされておらず、ネジ溝が形成されていない部分）を備えている。ネジ部２５ｂ１の上下方向における長さＮ１は、非ネジ部２５ｂ２の上下方向における長さＮ２よりも短くなっている（Ｎ１＜Ｎ２）。このような構成によれば、操作軸部２５ｂの全体にネジ部を形成した場合と比較して、基部２１のネジ孔２１ａに対する操作部材２５の操作量（ネジ回し量）が少なくなるため（つまり、ネジ締めの距離が短くなるため）、ワイヤ固定具２０を係合部２に固定する作業時間が短くなる。なお、ネジ部２５ｂ１の長さＮ１は、基部２１のネジ孔２１ａの高さ（深さ）と略一致している（換言すると、ネジ部２５ｂ１の長さＮ１は、螺合する基部２１の上下方向における板厚と同程度（例えば、基部２１の上下方向における板厚の±１０％、好ましくは±５％、より好ましくは±３％、更に好ましくは±２％、更により好ましくは±１％）であれば良い）。また、操作軸部２５ｂは、ボルトの中央部分を削ることで非ネジ部２５ｂ２が形成されているため、非ネジ部２５ｂ２の太さは、ネジ部２５ｂ１よりも細くなっている。 As shown in FIG. 4B, the operating shaft portion 25b includes, in order from the top, an operating head portion 25a, a threaded portion 25b1 (a threaded portion in which a thread groove is formed), and a non-threaded portion 25b2 (threaded portion). (not threaded and not threaded). The vertical length N1 of the threaded portion 25b1 is shorter than the vertical length N2 of the non-threaded portion 25b2 (N1<N2). According to such a configuration, the operation amount (screw turning amount) of the operation member 25 with respect to the screw hole 21a of the base portion 21 is reduced compared to the case where the screw portion is formed on the entire operation shaft portion 25b. , the screw tightening distance is shortened), the work time for fixing the wire fixture 20 to the engaging portion 2 is shortened. Note that the length N1 of the threaded portion 25b1 substantially matches the height (depth) of the threaded hole 21a of the base portion 21 (in other words, the length N1 of the threaded portion 25b1 is the height of the base portion 21 to be screwed together). about the same as the plate thickness in the direction (for example, ±10% of the plate thickness in the vertical direction of the base 21, preferably ±5%, more preferably ±3%, more preferably ±2%, still more preferably ±1% ) is good). Further, since the operation shaft portion 25b has the non-threaded portion 25b2 formed by cutting the central portion of the bolt, the thickness of the non-threaded portion 25b2 is thinner than that of the threaded portion 25b1.

支持部材２６は、図３乃至図７に示すように、上端の支持頭部２６ａと、支持頭部２６ａに接続された支持軸部２６ｂと、支持部材２６の下端に取り付けられたナット２６ｃと、を有している。ワイヤ固定具２０の基部２１には、上下方向に貫通したルーズ孔２１ｂ（ネジ部が形成されていない貫通孔）が形成されており、このルーズ孔２１ｂに支持部材２６の支持軸部２６ｂが挿通されている。また、支持部材２６の下端側は、ナット２６ｃが取り付けられており、第二係止部２４に対して保持されている。 3 to 7, the support member 26 includes a support head 26a at the upper end, a support shaft 26b connected to the support head 26a, a nut 26c attached to the lower end of the support member 26, have. The base portion 21 of the wire fixture 20 is formed with a loose hole 21b (a through hole in which no threaded portion is formed) penetrating in the vertical direction. It is A nut 26 c is attached to the lower end side of the support member 26 and held by the second locking portion 24 .

作業者は、ワイヤ固定具２０を、鉄骨柱１に取り付ける際、操作部材２５の操作頭部２５ａを回転させて、図４Ａに示すように、ワイヤ固定具２０の第二係止部２４を上方（図４Ａの矢印Ａ方向）に押し上げる。第二係止部２４が上方に配置されている状態では、第一係止片２３ａの先端と第二係止片２４ａの先端との距離Ｄ１が、係合部２の上下方向の長さＬ１より長くなる。そのため、第一係止部２３と第二係止部２４との間に係合部２を配置することができる。 When attaching the wire fixing device 20 to the steel frame column 1, the operator rotates the operating head 25a of the operating member 25 to move the second locking portion 24 of the wire fixing device 20 upward as shown in FIG. 4A. (in the direction of arrow A in FIG. 4A). When the second locking portion 24 is arranged upward, the distance D1 between the tip of the first locking piece 23a and the tip of the second locking piece 24a is equal to the length L1 of the engaging portion 2 in the vertical direction. be longer. Therefore, the engaging portion 2 can be arranged between the first locking portion 23 and the second locking portion 24 .

係合部２を第一係止部２３と第二係止部２４との間に配置した後、作業者は、操作部材２５の操作頭部２５ａをレンチなどの工具を用いて回転させることで、第二係止部２４を下方（図５の矢印Ｂ方向）に移動させる。このようにして、第一係止部２３の第一係止片２３ａが、係合部２の下端側の開口部２ｂのそれぞれに挿入されるとともに、第二係止部２４の第二係止片２４ａが係合部２の上端側部の開口部２ａに挿入される。 After arranging the engaging portion 2 between the first locking portion 23 and the second locking portion 24, the operator rotates the operating head portion 25a of the operating member 25 using a tool such as a wrench. , the second locking portion 24 is moved downward (in the direction of arrow B in FIG. 5). Thus, the first locking piece 23a of the first locking portion 23 is inserted into each of the openings 2b on the lower end side of the engaging portion 2, and the second locking portion 24 of the second locking portion 24 is inserted in this way. The piece 24 a is inserted into the opening 2 a on the upper end side of the engaging portion 2 .

そして、図５に示すように、係合部２の長さＬ１より、第一係止片２３ａの先端と第二係止片２４ａの先端との距離Ｄ２が短くなる。操作部材２５の操作軸部２５ｂに形成されたネジ部２５ｂ１が、基部２１に形成されたネジ孔２１ａに螺合しているため、操作部材２５及び支持部材２６は基部２１に対して自由に移動することがない。換言すると、操作部材２５の操作軸部２５ｂに形成されたネジ部２５ｂ１と、基部２１に形成されたネジ孔２１ａにより、第二係止部２４（第二係止片２４ａ）の上下移動を阻止するロック機構を構成している。このような構成によれば、第一係止片２３ａ及び第二係止片２４ａが係合部２の上下の開口部２ａ，２ｂから外れ難くなり、ワイヤ固定具２０を係合部２に確実に固定することができる。 Then, as shown in FIG. 5, the distance D2 between the tip of the first locking piece 23a and the tip of the second locking piece 24a is shorter than the length L1 of the engaging portion 2. As shown in FIG. Since the screw portion 25b1 formed in the operation shaft portion 25b of the operation member 25 is screwed into the screw hole 21a formed in the base portion 21, the operation member 25 and the support member 26 can move freely with respect to the base portion 21. I have nothing to do. In other words, the screw portion 25b1 formed in the operation shaft portion 25b of the operation member 25 and the screw hole 21a formed in the base portion 21 prevent the second locking portion 24 (second locking piece 24a) from moving up and down. It constitutes a locking mechanism that With such a configuration, the first locking piece 23a and the second locking piece 24a are less likely to come off from the upper and lower openings 2a and 2b of the engaging portion 2, so that the wire fixture 20 can be securely attached to the engaging portion 2. can be fixed to

また、作業者はワイヤ固定具２０の基部２１のネジ孔２１ａに螺合した操作部材２５を回転させるという簡易な操作で第二係止部２４を上下方向に移動できる。さらに、操作部材２５が基部２１のネジ孔２１ａに螺合しているため、第二係止部２４の第二係止片２４ａが鉄骨柱１の係合部２から離脱してしまうことが防止される。したがって、ワイヤ固定具２０の鉄骨柱１への取り付けが容易であり、且つ鉄骨柱１を確実に保持して建て起こして懸吊することが可能となる。 Further, the operator can move the second locking portion 24 vertically by a simple operation of rotating the operation member 25 screwed into the screw hole 21 a of the base portion 21 of the wire fixture 20 . Furthermore, since the operation member 25 is screwed into the screw hole 21a of the base portion 21, the second locking piece 24a of the second locking portion 24 is prevented from being separated from the engaging portion 2 of the steel frame column 1. be done. Therefore, the wire fixture 20 can be easily attached to the steel column 1, and the steel column 1 can be securely held, erected, and suspended.

また、ワイヤ固定具２０は、第二係止部２４に接続され、第二係止部２４を支持する支持部材２６を有し、支持部材２６は、上端の支持頭部２６ａと、支持頭部２６ａに接続された支持軸部２６ｂと、を有している。そして、ワイヤ固定具２０の基部２１には、上下方向に貫通したルーズ孔２１ｂが形成されており、ルーズ孔２１ｂに支持軸部２６ｂが挿通されている。このように、第二係止部２４が基部２１のルーズ孔２１ｂに挿通された支持部材２６に支持されていることで、支持部材２６がガイド機能を発揮するため、操作部材２５の操作による第二係止部２４の上下方向における移動が安定したものとなる。 The wire fixture 20 also has a support member 26 that is connected to the second locking portion 24 and supports the second locking portion 24. The support member 26 includes a support head 26a at the upper end and a support head 26a. and a support shaft portion 26b connected to 26a. A loose hole 21b penetrating vertically is formed in the base portion 21 of the wire fixture 20, and the support shaft portion 26b is inserted through the loose hole 21b. In this way, since the second locking portion 24 is supported by the support member 26 inserted through the loose hole 21b of the base portion 21, the support member 26 exhibits a guide function. The vertical movement of the second locking portion 24 is stabilized.

また、操作頭部２５ａは、多角形状の外形（本実施形態では、六角形状）を有し、支持頭部２６ａは、円形状の外形を有している。このような構成では、第二係止部２４を上下方向に移動させる際に、作業者は操作をすべき操作頭部２５ａを判別できる。そして、作業者は、モンキーレンチや六角ソケットレンチなどの器具（工具）を用いて多角形状の操作頭部２５ａを回転させることで、十分に第二係止部２４を下方へと移動させることができるため、係合部２に対して第二係止部２４を適切に係合させることが可能となる。 The operating head 25a has a polygonal outer shape (hexagonal in this embodiment), and the supporting head 26a has a circular outer shape. With such a configuration, the operator can determine the operation head 25a to be operated when moving the second locking portion 24 in the vertical direction. Then, the operator can fully move the second locking portion 24 downward by rotating the polygonal operating head 25a using an instrument (tool) such as a monkey wrench or a hexagonal socket wrench. Therefore, it is possible to appropriately engage the second locking portion 24 with the engaging portion 2 .

また、基部２１は、ヘッド部材１２から延びるワイヤ１５の下端に設けられたフック１６を掛ける環状部２７を有する。環状部２７は、基部２１の上面に固定される。環状部２７は、基部２１に対して上下方向を中心軸として、図７の矢印Ｄ方向に回転可能に固定されてもよい。環状部２７を回転可能に取り付けることで、例えばフック１６を掛けた後、ワイヤ１５がねじれたとしても、環状部２７を回転させることでねじれを解消することができる。 The base portion 21 also has an annular portion 27 for hooking a hook 16 provided at the lower end of the wire 15 extending from the head member 12 . The annular portion 27 is fixed to the upper surface of the base portion 21 . The annular portion 27 may be fixed to the base portion 21 so as to be rotatable in the direction of arrow D in FIG. 7 with the vertical direction as the central axis. By rotatably attaching the annular portion 27 , for example, even if the wire 15 is twisted after the hook 16 is hooked, the twist can be eliminated by rotating the annular portion 27 .

本実施形態では、第一係止部２３の第一係止片２３ａ及び第二係止部２４の第二係止片２４ａは、それぞれ二つ設けられているが、第一係止片２３ａ、第二係止片２４ａは、係合部２の開口部２ａ，２ｂの数に合わせて、１つ設けられていてもよいし、３つ以上設けられてよい。第一係止片２３ａ、第二係止片２４ａを複数設けることで、ワイヤ固定具２０を傾けることなく安定して係合部２に取り付けることができる。 In this embodiment, two first locking pieces 23a of the first locking portion 23 and two second locking pieces 24a of the second locking portion 24 are provided. One second locking piece 24a may be provided according to the number of openings 2a and 2b of the engaging portion 2, or three or more thereof may be provided. By providing a plurality of the first locking pieces 23a and the second locking pieces 24a, the wire fixture 20 can be stably attached to the engaging portion 2 without being tilted.

［２．柱吊治具１０を用いた柱の建て起こし及び設置方法について］
図８Ａ乃至図８Ｄに、本実施形態の柱吊治具１０の使用状態を示す。図８Ａに示すように、柱吊治具１０は、横倒し状態で枕木３１の上に仮置きされた鉄骨柱１に取り付けられる。まず、ヘッド部材１２が、鉄骨柱１が立設されたときに上方になる柱頭部１ａに被さるよう装着される。このとき、ヘッド部材１２の側面１２ｂに形成されたスリット１２ｃに鉄骨柱１の柱頭部１ａが備えるガセットプレート１ｂが受容される。 [2. Regarding the erection and installation method of the pillar using the pillar hanging jig 10]
8A to 8D show how the pillar hanging jig 10 of this embodiment is used. As shown in FIG. 8A, the pillar hanging jig 10 is attached to the steel frame pillar 1 temporarily placed on the sleeper 31 in a sideways state. First, the head member 12 is mounted so as to cover the stigma 1a that is positioned upward when the steel column 1 is erected. At this time, the gusset plate 1b provided on the column head 1a of the steel frame column 1 is received in the slit 12c formed in the side surface 12b of the head member 12. As shown in FIG.

ヘッド部材１２を装着した後、ヘッド部材１２とワイヤ固定具２０とを、ワイヤ１５により接続する。ワイヤ１５の両端に、フック機構を有するフック１６，１７が設けられていると、容易にワイヤ１５をヘッド部材１２とワイヤ固定具２０に取り付けることができる。そして、上述した手順に従い、ワイヤ固定具２０を、鉄骨柱１が立設されたときに下方に位置する係合部２に取り付ける。このとき、ワイヤ１５が備える不図示のターンバックルを操作して、ワイヤ１５の長さを適宜調整する。 After mounting the head member 12 , the head member 12 and the wire fixture 20 are connected by the wire 15 . If hooks 16 and 17 having hook mechanisms are provided at both ends of the wire 15 , the wire 15 can be easily attached to the head member 12 and the wire fixture 20 . Then, according to the procedure described above, the wire fixture 20 is attached to the engaging portion 2 positioned below when the steel column 1 is erected. At this time, the length of the wire 15 is appropriately adjusted by operating a turnbuckle (not shown) provided for the wire 15 .

次に、ヘッド部材１２を、ワイヤ１４を介してクレーン（吊り上げ装置）に接続する。そして、クレーンを作動させヘッド部材１２を吊り上げる。図８Ｂに示すように、ヘッド部材１２が吊り上げられると、鉄骨柱１が徐々に立ち上がる。鉄骨柱１が立設するまで、クレーンでの引き上げを行う。 The head member 12 is then connected to a crane (lifting device) via wires 14 . Then, the crane is operated and the head member 12 is lifted. As shown in FIG. 8B, when the head member 12 is lifted, the steel column 1 gradually rises. Until the steel frame column 1 is erected, it is pulled up by a crane.

鉄骨柱１を立設させた後、図８Ｃに示すように、さらにクレーンにより鉄骨柱１を吊り上げて、鉄骨柱１を設置する場所まで移動させる。鉄骨柱１を設置する基礎３２まで移動させた後、図８Ｄに示すように、鉄骨柱１を下して、鉄骨柱１の柱プレート３０の貫通孔３０ａにアンカーボルト３３を挿入して基礎３２に固定する。 After erecting the steel column 1, as shown in FIG. 8C, the steel column 1 is further lifted by a crane and moved to a place where the steel column 1 is installed. After moving the steel column 1 to the foundation 32 to be installed, as shown in FIG. fixed to

そして、操作部材２５の操作頭部２５ａをレンチなどの工具を用いて回転させて第二係止部２４を上方へと移動させ、第二係止片２４ａを係合部２の上側の開口部２ａから脱係合させる。このようにして、ワイヤ固定具２０を、鉄骨柱１の係合部２から取り外す。作業者は、操作部材２５の操作頭部２５ａを回転させるという簡易な操作により、ワイヤ固定具２０の第二係止部２４（第二係止片２４ａ）を上下に移動させることができるため、ワイヤ固定具２０を時間や手間をかけることなく容易に着脱することができる。 Then, the operating head portion 25a of the operating member 25 is rotated using a tool such as a wrench to move the second locking portion 24 upward, and the second locking piece 24a moves toward the upper opening of the engaging portion 2. Disengage from 2a. Thus, the wire fixture 20 is removed from the engaging portion 2 of the steel column 1 . The operator can move the second locking portion 24 (second locking piece 24a) of the wire fixture 20 up and down by a simple operation of rotating the operating head portion 25a of the operating member 25. The wire fixture 20 can be easily attached and detached without spending time and effort.

次に、ワイヤ１５のフック１６とワイヤ固定具２０との連結を解除し、その後、クレーンによりヘッド部材１２を更に吊り上げて鉄骨柱１の柱頭部１ａから取り外して撤去する。ヘッド部材１２は鉄骨柱１の柱頭部１ａを囲むようにして被さっているだけなのでクレーンで上方向（図８Ｄの矢印Ｄ方向）に吊り上げるだけで外すことができる。作業員が、柱吊治具１０を取り外す作業は、鉄骨柱１の下側で行われるため、高所作業が伴うことがなく安全である。 Next, the connection between the hook 16 of the wire 15 and the wire fixture 20 is released, and then the head member 12 is further lifted by a crane to be removed from the stigma 1a of the steel column 1 and removed. Since the head member 12 simply covers the stigma 1a of the steel frame column 1 so as to surround it, it can be removed by simply lifting it upward (in the direction of arrow D in FIG. 8D) with a crane. Since the worker removes the pillar hanging jig 10 under the steel frame pillar 1, it is safe because it does not involve work at height.

［３．変形例］
以上までに本発明の柱吊治具に関して、その構成及び利用方法についての一実施形態を例に挙げて説明してきたが、上述の実施形態は、あくまでも一例に過ぎず、他の例も考えられる。 [3. Modification]
As described above, an embodiment of the configuration and usage of the pillar suspension jig of the present invention has been described as an example, but the above-described embodiment is merely an example, and other examples are also possible. .

変形例に係る柱吊治具１０Ｘを、図９及び図１０に示す。変形例に係る柱吊治具１０Ｘは、上述したヘッド部材１２とワイヤ固定具２０との間のワイヤ１５の態様が異なっている。以下、上記の柱吊治具１０と同じ構成については説明を省略し、異なる点を中心に説明をする。 A column suspension jig 10X according to a modification is shown in FIGS. 9 and 10. FIG. The pole suspension jig 10X according to the modification differs in the aspect of the wire 15 between the head member 12 and the wire fixture 20 described above. Hereinafter, the description of the same configuration as that of the above-described pillar suspension jig 10 will be omitted, and the description will focus on the points of difference.

図９に模式的に示すように、変形例に係る柱吊治具１０Ｘは、ヘッド部材１２とワイヤ固定具２０との間に上部連結部材１５Ｘａ及び下部連結部材１５Ｘｂが接続されてなる連結部材を有している。上部連結部材１５Ｘａは、上端がヘッド部材１２に接続されている。下部連結部材１５Ｘｂは、上端が上部フック１６Ｘａを介して上部連結部材１５Ｘａに接続されており、下端が下部フック１６Ｘｂを介してワイヤ固定具２０の環状部２７に連結されている。そして、下部連結部材１５Ｘｂは、長さ調節可能である。 As schematically shown in FIG. 9, a post hanging jig 10X according to a modification includes a connecting member in which an upper connecting member 15Xa and a lower connecting member 15Xb are connected between a head member 12 and a wire fixture 20. have. The upper connecting member 15Xa is connected to the head member 12 at its upper end. The lower connecting member 15Xb has an upper end connected to the upper connecting member 15Xa via an upper hook 16Xa, and a lower end connected to the annular portion 27 of the wire fixture 20 via a lower hook 16Xb. The length of the lower connecting member 15Xb is adjustable.

具体的には、図１０に示すように、下部連結部材１５Ｘｂを長さ調節可能なチェーンスリングとすることで、異なる高さの鉄骨柱１であっても柱吊治具１０Ｘで対応することが可能となる。 Specifically, as shown in FIG. 10, by using a chain sling whose length can be adjusted as the lower connecting member 15Xb, the steel frame columns 1 having different heights can be handled by the column suspension jig 10X. It becomes possible.

このとき、ヘッド部材１２に連結させる上部連結部材１５Ｘａをワイヤスリングで構成し、下部連結部材１５Ｘｂを長さ調節可能なチェーンスリングで構成すると良い。このような構成によれば、ヘッド部材１２が動く際に力の加わり易い上側の上部連結部材１５Ｘａを張力に強いワイヤスリングとしつつ、チェーンスリングである下部連結部材１５Ｘｂを適切な長さに調整して、ワイヤ固定具２０を係合部２に取り付ける作業を行いやすくなる。 At this time, it is preferable that the upper connecting member 15Xa to be connected to the head member 12 is composed of a wire sling, and the lower connecting member 15Xb is composed of a chain sling whose length is adjustable. According to such a configuration, while the upper upper connecting member 15Xa to which force is likely to be applied when the head member 12 moves is a wire sling that is resistant to tension, the lower connecting member 15Xb, which is a chain sling, is adjusted to an appropriate length. Thus, the work of attaching the wire fixture 20 to the engaging portion 2 is facilitated.
