Description

本発明は、吊りワイヤーを連結するための吊りピースを備えた吊りピース付きコラム切梁に用いられるコラム切梁用吊り治具に関し、吊りピース付きコラム切梁をクレーン等で吊る際に、コラム切梁の重心の位置がずれている場合でも、重心の位置を簡単に補正して水平に吊ることができるようにしたものである。 The present invention relates to a hanging jig for a column cutting beam used for a column cutting beam with a hanging piece provided with a hanging piece for connecting the hanging wire, and the column cutting is performed when the column cutting beam with a hanging piece is hung by a crane or the like. Even if the position of the center of gravity of the beam is deviated, the position of the center of gravity can be easily corrected so that the beam can be hung horizontally.

近年、山留め壁を支える切梁にコラム切梁(角形鋼管)が利用されている。コラム切梁は、架設に際してＨ形鋼切梁のように断面の向きに特に配慮する必要がなく、また中間杭や火打ち梁による補強も原則不要なため近年需要が増大している。 In recent years, column girders (square steel pipes) have been used for girders that support mountain retaining walls. Demand for column beams has been increasing in recent years because it is not necessary to pay special attention to the orientation of the cross section when erection, and reinforcement by intermediate piles or flint beams is not necessary in principle.

しかし、コラム切梁には、運搬等でクレーンで吊る際に、吊りワイヤーの先端部に取り付けられた吊り具を連結することができないという不便さがある。 However, the column beam has the inconvenience that the hanging tool attached to the tip of the hanging wire cannot be connected when hanging with a crane for transportation or the like.

このため、コラム切梁をクレーンで吊る際は、吊りワイヤーをコラム切梁に巻き付ける等して吊る必要があるため、クレーンによる取り扱いが面倒であり、また、吊りワイヤーがずれて落下するおそれがあり、作業の安全性にも問題があった。 For this reason, when suspending a column beam with a crane, it is necessary to hang the suspension wire by winding it around the column beam, which is troublesome to handle with a crane, and the suspension wire may slip and fall. , There was also a problem with work safety.

そこで、出願人は、先に吊りワイヤーの吊り具を連結するための吊りピースを備えた吊りピース付きコラム切梁を開発し、すでに出願もしている(特許文献１ 図1,2参照)。 Therefore, the applicant has previously developed a column girder with a hanging piece provided with a hanging piece for connecting the hanging tool of the hanging wire, and has already filed an application (see Patent Document 1, FIGS. 1 and 2).

特許文献１には、コラム切梁本体(2)とコラム切梁本体(2)の両側に取り付けられた複数の吊りピース(3)とからなる吊りピース付きコラム切梁(1)の考案が開示されている。特に、吊りピース(3)はコラム切梁本体(2)の材軸方向の両側部に、コラム切梁本体(2)の重心Ｇを通る鉛直軸に対して対称な位置に、かつコラム切梁本体(2)の材軸方向に間隔をおいて複数取り付けられている。 Patent Document 1 discloses a invention of a column girder (1) with a hanging piece, which is composed of a column girder main body (2) and a plurality of hanging pieces (3) attached to both sides of the column girder main body (2). Has been done. In particular, the suspension piece (3) is located on both sides of the column girder body (2) in the material axis direction, at a position symmetrical to the vertical axis passing through the center of gravity G of the column girder body (2), and the column girder. Multiple pieces are attached at intervals in the material axis direction of the main body (2).

そして、クレーンで吊る際は、コラム切梁本体(2)の重心Ｇを通る鉛直軸に対して対称な位置の少なくとも二か所の吊りピース(3)に吊りワイヤー(5)の吊り具(4)を連結して吊ることによりコラム切梁を水平に吊り上げることができる。 Then, when suspending with a crane, the suspending tool (4) of the suspension wire (5) is attached to at least two suspension pieces (3) at positions symmetrical to the vertical axis passing through the center of gravity G of the column cutting beam body (2). ) Can be connected and hung to lift the column girder horizontally.

また、コラム切梁(1)を架設する際や撤去する際に、コラム切梁(1)の端部に長さ調整材やジャッキ(図省略)等の付属品を取り付けたまま吊り上げる場合があり、付属品を取り付けたまま吊り上げると、コラム切梁(1)の重心Ｇがずれて傾いてしまうおそれがあった。そこで出願人は、このような場合に対処できる補助吊りピースを開発した（特許文献１ 図３参照）。 In addition, when installing or removing the column beam (1), it may be lifted with accessories such as a length adjusting material and a jack (not shown) attached to the end of the column beam (1). If the column beam (1) is lifted with the accessories attached, the center of gravity G of the column beam (1) may be displaced and tilted. Therefore, the applicant has developed an auxiliary hanging piece that can deal with such a case (see Patent Document 1, FIG. 3).

補助吊りピース(6)は、コラム切梁本体(2)の材軸方向に長い矩形板状に形成され、かつコラム切梁本体(2)側にコラム切梁本体(2)の上面に沿ってコラム切梁本体(2)の軸直角方向に突出する複数の補強リブ(6c)が取り付けられている。 The auxiliary suspension piece (6) is formed in the shape of a rectangular plate long in the material axis direction of the column girder body (2), and is formed on the column girder body (2) side along the upper surface of the column girder body (2). A plurality of reinforcing ribs (6c) protruding in the direction perpendicular to the axis of the column beam body (2) are attached.

また、上部縁端に吊りワイヤー(5)の吊り具(4)を連結するための吊り孔(6a)がコラム切梁本体(2)の材軸方向に等間隔に複数形成され、また、材軸方向の両端部には吊りピース(3)にボルト付けするための取付け孔(6b)が形成されている。 In addition, a plurality of suspension holes (6a) for connecting the suspension tool (4) of the suspension wire (5) are formed at the upper edge end at equal intervals in the material axial direction of the column beam body (2), and the material is also formed. Mounting holes (6b) for bolting to the suspension piece (3) are formed at both ends in the axial direction.

特許文献１の図３に開示された補助吊りピース(6)は、コラム切梁本体(2)の材軸方向に隣接する二つの吊りピース(3),(3)間に架け渡して設置する程の長さに形成されているため、非常に重く取付けおよび取り外し時の取り扱いを一人で行うのは困難で、特に補助吊りピース(6)とコラム切梁本体(2)との間に誤って指を挟んで思わぬケガをするおそれがあった。 The auxiliary suspension piece (6) disclosed in FIG. 3 of Patent Document 1 is installed so as to be bridged between two suspension pieces (3) and (3) adjacent to each other in the material axial direction of the column cutting beam main body (2). Due to its length, it is very heavy and difficult to handle when installing and removing, especially between the auxiliary suspension piece (6) and the column beam body (2). There was a risk of unexpected injury by pinching a finger.

また、長く形成されているにもかかわらず、コラム切梁本体(2)側にのみ補強リブ(6c)が取り付けられているため、両端の吊りピース(3),(3)に大きな負荷がかかるおそれがあり、また、横方向の荷重に弱いため、横倒れしやすく強度面および安定性に課題があった。 In addition, although it is formed long, the reinforcing ribs (6c) are attached only to the column cutting beam body (2) side, so that a large load is applied to the suspension pieces (3) and (3) at both ends. In addition, since it is vulnerable to a lateral load, it is liable to fall sideways, and there are problems in terms of strength and stability.

本発明は、特許文献１の図３に図示する補助吊りピースを改良発展させたものであり、軽量で取扱いが容易で、しかも安定性と強度面に優れたコラム切梁用吊り治具を提供することを目的とするものである。 INDUSTRIAL APPLICABILITY The present invention is an improved development of the auxiliary suspension piece shown in FIG. 3 of Patent Document 1, and provides a suspension jig for a column cutting beam which is lightweight, easy to handle, and has excellent stability and strength. The purpose is to do.

本発明は、角形鋼管からなるコラム切梁本体と当該コラム切梁本体の長手方向両側部に取り付けられ、吊りワイヤーが連結される複数の吊りピースとを備えた吊りピース付きコラム切梁に脱着可能に取り付けられるコラム切梁用吊り治具の発明であり、前記コラム切梁本体の長手方向に長尺に形成され、かつ前記吊りピースの前記コラム切梁本体側の側部に設置された治具本体と、当該治具本体の前記コラム切梁本体とは反対側の側面部に取り付けられた複数の縦リブと、前記コラム切梁側の側面部に取り付けられた複数の横リブとを備え、前記治具本体は前記吊りワイヤーが連結される連結孔を前記コラム切梁本体の長手方向に間隔をおいて複数備え、前記縦リブは前記コラム切梁本体の側面に沿って下方に垂設され、前記横リブは前記コラム切梁本体の上面に沿って前記コラム切梁本体の長手方向と直交する方向に突設されていることを特徴とするものである。 The present invention can be attached to and detached from a column girder body made of a square steel pipe and a column girder with a hanging piece attached to both sides of the column girder body in the longitudinal direction and having a plurality of hanging pieces to which a hanging wire is connected. It is an invention of a hanging jig for a column cutting beam to be attached to a beam, which is formed long in the longitudinal direction of the column cutting beam body and is installed on the side portion of the hanging piece on the column cutting beam main body side. The main body is provided with a plurality of vertical ribs attached to the side surface portion of the jig main body opposite to the column cutting beam main body, and a plurality of horizontal ribs attached to the side surface portion of the column cutting beam side. The jig body is provided with a plurality of connecting holes to which the suspension wires are connected at intervals in the longitudinal direction of the column beam body, and the vertical ribs are vertically laid down along the side surface of the column beam body. The lateral rib is characterized in that it projects along the upper surface of the column cutting beam body in a direction orthogonal to the longitudinal direction of the column cutting beam body.

コラム切梁の端部に長さ調整材などの付属品が接続されている等の理由で、コラム切梁の重心Ｇがずれている場合でも、吊りピースと吊りワイヤーの吊り具との間に本発明の吊り治具を介在することで、コラム切梁の重心の位置を簡単補正することでき、これによりコラム切梁を水平に吊ることができる。 Even if the center of gravity G of the column beam is misaligned due to the connection of accessories such as a length adjuster to the end of the column beam, it is still between the suspension piece and the suspension of the suspension wire. By interposing the hanging jig of the present invention, the position of the center of gravity of the column girder can be easily corrected, whereby the column girder can be hung horizontally.

また、コラム切梁本体の側部に取り付けられた複数の吊りピースの中の一つに脱着可能に取り付けることで、取付けおよび取外し時の取り扱いを簡単にすることができる。 Further, by detachably attaching to one of the plurality of hanging pieces attached to the side portion of the column beam body, it is possible to simplify the handling at the time of attachment and detachment.

また、治具本体の両側部にコラム切梁本体の側面と上面に沿ってそれぞれ突出する縦リブと横リブを取り付けることで、特に横方向の衝撃荷重に対する抵抗力を高めて安定性を向上させることができる。 In addition, by attaching vertical ribs and horizontal ribs that project along the side and top surfaces of the column cutting beam body on both sides of the jig body, the resistance to impact load in the lateral direction is increased and the stability is improved. be able to.

また、前記治具本体の下端部に、前記コラム切梁本体に取り付けられている安全設備取付けプレート(スタンション)を回避するための切欠きを形成することで、吊りピースの近くに安全設備取付けプレートが設置されている場合でも、これを回避して取り付けることができる。また、取付けや取外しの際に、コラム切梁本体と治具本体との間に指を挟んでしまうことも回避することができる。 Further, by forming a notch at the lower end of the jig main body to avoid the safety equipment mounting plate (stanchion) attached to the column cutting beam main body, the safety equipment mounting plate is placed near the suspension piece. Even if it is installed, it can be installed by avoiding this. Further, it is possible to prevent a finger from being caught between the column cutting beam main body and the jig main body at the time of attachment / detachment.

さらに、前記治具本体の側面部に補強リブを取り付けることにより、特に治具本体の下縁端部に切欠きを設けたことによる治具本体の強度低下を防止することができる。 Further, by attaching the reinforcing rib to the side surface portion of the jig body, it is possible to prevent the strength of the jig body from being lowered due to the provision of the notch at the lower edge end portion of the jig body.

本発明は、コラム切梁本体の側部に取り付けられた複数の吊りピースの中の一つに脱着可能に取り付けることできるため、取付けおよび取外し時の取り扱いがきわめて簡単である。 Since the present invention can be detachably attached to one of a plurality of hanging pieces attached to the side portion of the column girder body, it is extremely easy to handle at the time of attachment and detachment.

また、治具本体の両側にコラム切梁本体の側面と上面に沿ってそれぞれ突出する縦リブと横リブを有することで、特に横倒れしにくく横方向の安定性が高く、また、剛性が高く強度も大きい。 In addition, by having vertical ribs and horizontal ribs protruding along the side surface and the upper surface of the column cutting beam body on both sides of the jig body, it is particularly difficult to fall sideways, and the lateral stability is high, and the rigidity is high. The strength is also great.

また、治具本体の下端部に、コラム切梁本体に取り付けられている安全設備取付けプレート(スタンション)を回避するための切欠きが形成されていることで、安全設備取付けプレートの近く取り付けられている吊りピースにも設置することができる。 In addition, a notch is formed at the lower end of the jig body to avoid the safety equipment mounting plate (stanchion) attached to the column cutting beam body, so that it can be mounted near the safety equipment mounting plate. It can also be installed on a hanging piece.

＜実施形態１＞
図１～図３は、本発明の一実施形態であり、吊りピース付きコラム切梁(以下「コラム切梁」)と、当該コラム切梁の吊りピースに取り付けられた本発明の吊り治具を図示したものである。 <Embodiment 1>
1 to 3 are embodiments of the present invention, wherein a column girder with a hanging piece (hereinafter referred to as “column girder”) and a hanging jig of the present invention attached to the hanging piece of the column girder are used. It is illustrated.

図において、吊りワイヤー１の先端部に取り付けられた吊り具２は、コラム切梁３の複数ある吊りピース４の中の一つに吊り治具５を介して連結されている。 In the figure, the hanging tool 2 attached to the tip of the hanging wire 1 is connected to one of the plurality of hanging pieces 4 of the column cutting beam 3 via the hanging jig 5.

コラム切梁３は、コラム切梁本体６と当該コラム切梁本体６の長手方向両側部に取り付けられた複数の吊りピース４とから構成されている。 The column girder 3 is composed of a column girder main body 6 and a plurality of suspension pieces 4 attached to both sides of the column girder main body 6 in the longitudinal direction.

各吊りピース４は縦長の板状に形成され、コラム切梁本体６の側面部に溶接によって取り付けられ、その上部(以下、「立上り部4a」)の一定長がコラム切梁本体６の上面より上方に鉛直に立ち上げられている。また、吊りピース４の立上り部4aに吊りワイヤー１の吊り具２を連結するための連結孔７がコラム切梁本体６の長手方向と直交する方向に貫通して複数形成されている。 Each suspension piece 4 is formed in a vertically long plate shape and is attached to the side surface portion of the column girder body 6 by welding, and a fixed length of the upper portion thereof (hereinafter, “rising portion 4a”) is from the upper surface of the column girder body 6. It is launched vertically upward. Further, a plurality of connecting holes 7 for connecting the hanging tool 2 of the hanging wire 1 are formed through the rising portion 4a of the hanging piece 4 in a direction orthogonal to the longitudinal direction of the column cutting beam main body 6.

さらに、吊りピース４は、コラム切梁本体６の重心付近の一定区間においては、コラム切梁本体６の両側に互いに対向し、かつコラム切梁本体６の長手方向に所定間隔おきに複数取り付けられ、また、コラム切梁本体６の長手方向両端側の一定区間においては、コラム切梁本体６の重心に対して点対称な複数の位置に所定間隔おきに取り付けられている。 Further, a plurality of suspension pieces 4 are attached to both sides of the column girder body 6 at regular intervals in the longitudinal direction of the column girder body 6 so as to face each other on both sides of the column girder body 6 in a certain section near the center of gravity of the column girder body 6. Further, in a certain section on both ends in the longitudinal direction of the column girder main body 6, they are attached at a plurality of positions symmetrical with respect to the center of gravity of the column girder main body 6 at predetermined intervals.

コラム切梁３がこのように構成されていることで、端部に長さ調整材やジャッキ等の付属品が連結されていなければ、コラム切梁１は、重心に対して点対称な二か所の吊りピース4,4に吊りワイヤー１の吊り具２を連結して吊ることにより水平に吊ることができる。しかし、端部に長さ調整材やジャッキ等の付属品が連結されていると、コラム切梁３は重心がずれて一方に傾いてしまう。 Since the column girder 3 is configured in this way, if accessories such as a length adjusting material and a jack are not connected to the end portion, the column girder 1 is point-symmetrical with respect to the center of gravity. It can be hung horizontally by connecting the hanging tool 2 of the hanging wire 1 to the hanging pieces 4 and 4 of the place. However, if accessories such as a length adjusting material and a jack are connected to the end portion, the center of gravity of the column beam 3 shifts and the column beam 3 tilts to one side.

このような場合に、吊りワイヤー１の吊り具２を吊りピース４に吊り治具５を介して連結することにより、コラム切梁３を水平に吊り上げることができる。 In such a case, the column cutting beam 3 can be lifted horizontally by connecting the hanging tool 2 of the hanging wire 1 to the hanging piece 4 via the hanging jig 5.

吊り治具５は、吊りピース４のコラム切梁本体６側の側面部に添い付けられた治具本体８と、当該治具本体８の側面部に取り付けられた複数の縦リブ９および横リブ10とを備えている。 The hanging jig 5 includes a jig main body 8 attached to the side surface portion of the hanging piece 4 on the column cutting beam main body 6 side, and a plurality of vertical ribs 9 and horizontal ribs attached to the side surface portion of the jig main body 8. It has 10 and.

治具本体８は、コラム切梁本体６の長手方向に長い矩形板状に形成され、かつ長辺方向中間の下端部に吊りピース４の連結孔７と連通する取付け孔11が形成されている。 The jig main body 8 is formed in the shape of a rectangular plate long in the longitudinal direction of the column cutting beam main body 6, and a mounting hole 11 communicating with the connecting hole 7 of the suspension piece 4 is formed at the lower end portion in the middle in the long side direction. ..

そして、連結孔７と取付け孔11間に取付けボルト12が締め付けられていることにより、吊り治具５は吊りピース４の立上り部4aに脱着可能に取り付けられている。 Then, by tightening the mounting bolt 12 between the connecting hole 7 and the mounting hole 11, the hanging jig 5 is detachably attached to the rising portion 4a of the hanging piece 4.

また、治具本体８の上端部に吊りワイヤー１の吊り具２を連結するための連結孔13がコラム切梁本体３の長手方向に等間隔に複数形成され、その中のひとつに吊り具２が連結ボルト14によって連結されている。 Further, a plurality of connecting holes 13 for connecting the hanging tool 2 of the hanging wire 1 are formed at the upper end of the jig main body 8 at equal intervals in the longitudinal direction of the column cutting beam main body 3, and the hanging tool 2 is one of them. Is connected by a connecting bolt 14.

縦リブ９は、治具本体８のコラム切梁本体６とは反対側の側面部に溶接によってほぼ直角に取り付けられ、かつコラム切梁本体６の側面に沿ってほぼ鉛直下方に所定長さ延長された状態に形成されている。 The vertical rib 9 is attached to the side surface portion of the jig body 8 opposite to the column cutting beam body 6 at a substantially right angle by welding, and extends substantially vertically downward along the side surface of the column cutting beam body 6 by a predetermined length. It is formed in the state of being welded.

また、縦リブ９は、治具本体８の長手方向の少なくとも両端部に取り付けられ、必要に応じて縦リブ9,9間にも１乃至複数等間隔に取り付けられている。 Further, the vertical ribs 9 are attached to at least both ends of the jig main body 8 in the longitudinal direction, and are also attached between the vertical ribs 9 and 9 at one or a plurality of equal intervals as needed.

横リブ10は、治具本体８のコラム切梁本体６側の側面部に溶接によってほぼ直角に取り付けられ、かつコラム切梁本体６の上面に沿ってコラム切梁本体６の長手方向と直交する方向に一定長さ延長された状態に形成されている。また、横リブ10は治具本体８の長手方向に等間隔に複数取り付けられている。 The lateral rib 10 is attached to the side surface of the jig body 8 on the column cutting beam body 6 side at a substantially right angle by welding, and is orthogonal to the longitudinal direction of the column cutting beam body 6 along the upper surface of the column cutting beam body 6. It is formed in a state of being extended by a certain length in the direction. Further, a plurality of horizontal ribs 10 are attached at equal intervals in the longitudinal direction of the jig main body 8.

このように、縦リブ９と横リブ10がそれぞれコラム切梁本体６の側面と上面に沿って所定長さに形成されていることで、吊りピース４の上部4aに吊り治具５が安定した状態に取り付けられ、特に治具本体８に作用する直角方向の衝撃荷重に対する抵抗力が大きいため、横倒れしにくく安定性に優れている。 As described above, the vertical ribs 9 and the horizontal ribs 10 are formed to a predetermined length along the side surface and the upper surface of the column cutting beam body 6, respectively, so that the suspension jig 5 is stabilized on the upper portion 4a of the suspension piece 4. Since it is attached in a state and has a large resistance to an impact load in the perpendicular direction acting on the jig body 8, it is difficult to fall sideways and has excellent stability.

このような構成において、吊り治具５を用いてコラム切梁３を吊る方法について説明すると、コラム切梁３の重心に対して点対称な位置の一方の吊り治具４に吊り治具５を取り付ける。 In such a configuration, a method of suspending the column cutting beam 3 using the suspension jig 5 will be described. The suspension jig 5 is attached to one suspension jig 4 at a position point-symmetrical to the center of gravity of the column cutting beam 3. Install.

そして、クレーンのフック(図省略)に吊りワイヤー１を巻かけ、その一端側の吊り具２を吊り治具５に連結し、他端側の吊り具(図省略)を他方の吊りピースに直接連結する。 Then, the hanging wire 1 is wound around the hook of the crane (not shown), the hanging tool 2 on one end side thereof is connected to the hanging jig 5, and the hanging tool on the other end side (not shown) is directly attached to the other hanging piece. connect.

特に、吊り治具５側の吊り具２は、コラム切梁３を水平に吊り上げることができるように吊り治具５の複数の連結孔13の中から一つを任意に選んで連結することでコラム切梁３を水平に吊ることができる。 In particular, the hanging tool 2 on the hanging jig 5 side is connected by arbitrarily selecting one from a plurality of connecting holes 13 of the hanging jig 5 so that the column cutting beam 3 can be lifted horizontally. The column cutting beam 3 can be hung horizontally.

Rope may be stretched in places where there is a risk of crashing, such as when working at heights or near openings, or a single pipe may be assembled to serve as a safety handrail.

このような場所には親柱や単管パイプを立て付けるための受け金物として、例えば、図４に図示するような安全設備取付けプレート(スタンション)15が取り付けられている。 In such a place, for example, a safety equipment mounting plate (stanchion) 15 as shown in FIG. 4 is mounted as a receiver for mounting a main pillar or a single pipe.

このような場所の吊りピース４には、図１～３で説明した吊り治具５を取り付けることができないが、図示する吊り治具16であれば難なく取り付けることができる。 The hanging jig 5 described with reference to FIGS. 1 to 3 cannot be attached to the hanging piece 4 in such a place, but the hanging jig 16 shown in the figure can be attached without difficulty.

安全設備取付けプレート15は、コラム切梁本体６の長手方向と直交する方向に長い矩形板状に形成され、例えばコラム切梁本体６の上に溶接することにより並列に取り付けられ、その両端部がコラム切梁本体６の両側に所定長さ伸びている。 The safety equipment mounting plate 15 is formed in the shape of a long rectangular plate in a direction orthogonal to the longitudinal direction of the column girder body 6, and is mounted in parallel by welding onto the column girder body 6, for example, at both ends thereof. It extends to both sides of the column girder body 6 by a predetermined length.

また、吊り治具16の形態は、基本的に図１～３に図示する吊り治具５と同じであり、図１～３で説明した吊り治具５の形態にさらに、治具本体８の下端部に安全設備取付けプレート15を回避するための切欠き17が形成されている。 Further, the form of the hanging jig 16 is basically the same as that of the hanging jig 5 shown in FIGS. 1 to 3, and the form of the hanging jig 5 described with reference to FIGS. A notch 17 for avoiding the safety equipment mounting plate 15 is formed at the lower end portion.

切欠き17は、安全設備取付けプレート15を回避できるだけの内法幅と深さに形成され、また、取付け孔11の両側に対称に形成されている。さらに、治具本体８の縦リブ９を有する側の側面部に補強リブ18と補強プレート19が取り付けられている。 The notch 17 is formed to have an internal width and depth sufficient to avoid the safety equipment mounting plate 15, and is formed symmetrically on both sides of the mounting hole 11. Further, the reinforcing rib 18 and the reinforcing plate 19 are attached to the side surface portion of the jig body 8 on the side having the vertical rib 9.

補強リブ18と補強プレート19は、治具本体８の下縁端部に切欠き17を有することによる治具本体８の強度低下を補強する部材であり、補強リブ18は各切欠き17の上側に治具本体８の長手方向に沿ってそれぞれ取り付けられている。 The reinforcing rib 18 and the reinforcing plate 19 are members for reinforcing the decrease in strength of the jig body 8 due to having the notch 17 at the lower edge end of the jig body 8, and the reinforcing rib 18 is the upper side of each notch 17. The jig body 8 is attached to the jig body 8 along the longitudinal direction.

また、補強プレート19は補強リブ18,18間に治具本体８と平行に添え付けられ、かつ両側の補強リブ18,18に溶接によって一体的に取り付けられている。 Further, the reinforcing plate 19 is attached between the reinforcing ribs 18 and 18 in parallel with the jig main body 8, and is integrally attached to the reinforcing ribs 18 and 18 on both sides by welding.

さらに、補強プレート19には、取付け孔20が治具本体８の取付け孔11と対向して形成されている。そして、吊り治具５の取付けボルトは、治具本体８および補強プレート19の二か所の取付け孔11,20に締め付けられている。 Further, the reinforcing plate 19 is formed with a mounting hole 20 facing the mounting hole 11 of the jig main body 8. The mounting bolts of the hanging jig 5 are fastened to the mounting holes 11 and 20 of the jig main body 8 and the reinforcing plate 19.

以上説明した構成により、吊り治具16であれば、近くに安全設備取付けプレート15が設置されている吊りピースであっても特に問題なく設置することができる。 With the configuration described above, the suspension jig 16 can be installed without any problem even if the suspension piece has the safety equipment mounting plate 15 installed nearby.

本発明は、コラム切梁の端部に長さ調整材などの付属品が接続されている等の理由で、コラム切梁の重心がずれている場合でも、重心の位置を補正して水平に吊ることができる。 In the present invention, even if the center of gravity of the column beam is deviated due to an accessory such as a length adjusting material being connected to the end of the column beam, the position of the center of gravity is corrected to be horizontal. Can be hung.
