Description

本発明は、構造物を吊上げる際に使用する吊上げ用治具及びこれを用いた構造物の吊上げ方法に関するものである。   The present invention relates to a lifting jig used for lifting a structure and a method for lifting a structure using the same.

図１１（ａ）は従来の構造物の吊上げ方法の一例を示す説明図である。図において、３０は吊上げる側面ほぼ凹状の構造物で、図には船体を分割した重量の大きい船体ブロックが示してある。
この構造物３０の前部側３１（上甲板）には、例えば配管群からなる障害物３４が設けられているため、吊上げに際してワイヤロープが干渉すると、障害物３４を損傷したり破壊したりするおそれがある。そのため保護部材により障害物３４を保護するようにしていたが、その装着、取外しがきわめて面倒である。このようなことから、障害物３４にワイヤロープが干渉しないようにした吊上げ方法が行われている。以下にこのような従来の構造物の吊上げ方法について説明する。 Fig.11 (a) is explanatory drawing which shows an example of the lifting method of the conventional structure. In the figure, reference numeral 30 denotes a structure having a substantially concave side surface to be lifted. In the figure, a heavy hull block obtained by dividing the hull is shown.
Since the front side 31 (upper deck) of the structure 30 is provided with an obstacle 34 made of, for example, a pipe group, if the wire rope interferes during lifting, the obstacle 34 is damaged or destroyed. There is a fear. For this reason, the obstacle 34 is protected by the protective member, but it is very troublesome to attach and remove it. For this reason, a lifting method in which the wire rope does not interfere with the obstacle 34 is performed. A conventional method for lifting such a structure will be described below.

図１１（ａ）において、前部側３１の下部の幅方向（図面の垂直方向）には所定の間隔で設けた複数の前部吊り環３３ａが設けられており、また障害物３４の上方には幅方向に所定の間隔で複数の上部吊り環３３ｃ，３３ｄがそれぞれ設けられている。また、後部側３２（船底）の上部の幅方向には所定の間隔で複数の後部吊り環３３ｂが設けられている。３５は前部側３１と後部側３２との間に設けられた補強材、３６は構造物３０の重心位置を示す。なお、４０は地上に設けられて構造物３０が載置される盤木である。   In FIG. 11A, a plurality of front suspension rings 33 a provided at predetermined intervals are provided in the width direction (vertical direction in the drawing) of the lower portion of the front side 31, and above the obstacle 34. Are provided with a plurality of upper suspension rings 33c and 33d at predetermined intervals in the width direction. A plurality of rear suspension rings 33b are provided at predetermined intervals in the width direction of the upper portion of the rear side 32 (ship bottom). Reference numeral 35 denotes a reinforcing material provided between the front side 31 and the rear side 32, and 36 denotes the position of the center of gravity of the structure 30. Reference numeral 40 denotes a board provided on the ground on which the structure 30 is placed.

上記のような構造物３０を吊上げるには、先ず、図１１（ａ）に示すように、上部がイコライザー天秤を介してクレーンに設けた第１のウインチのドラム（いずれも図示せず）に巻かれたワイヤロープ３７ａの下端部を上部吊り環３３ｃ，３３ｄにそれぞれ掛け、また、前部吊り環３３ａに一端がフリー状態にあるワイヤロープ３７ｂの他端を掛ける。さらに、後部吊り環３３ｂに、上部がイコライザー天秤を介してクレーンに設けた第２のウインチのドラムに巻かれたワイヤロープ３７ｃの下端部を掛ける。
そして、第１、第２のウインチによりワイヤロープ３７ａ，３７ｃを若干巻上げて、構造物３０を盤木４０から浮かせて、ワイヤロープ３７ｃを固定する。 In order to lift the structure 30 as described above, first, as shown in FIG. 11A, the upper part is attached to a drum of a first winch (not shown) provided on the crane via an equalizer balance. The lower end of the wound wire rope 37a is hung on the upper suspension rings 33c and 33d, respectively, and the other end of the wire rope 37b with one end in a free state is hung on the front suspension ring 33a. Furthermore, the lower part of the wire rope 37c wound around the drum of the second winch provided on the crane is hung on the rear suspension ring 33b via the equalizer balance.
Then, the wire ropes 37a and 37c are slightly wound up by the first and second winches, the structure 30 is lifted from the board 40, and the wire rope 37c is fixed.

次に、第１のウインチによりワイヤロープ３７ａを巻上げて、図１１（ｂ）に示すように構造物３０の前部側３１を引き上げ、構造物３０を回転させて傾斜させ、ワイヤロープ３７ａを固定する。そして、構造物３０の下に高所作業車３８を移動し、ワイヤロープ３７ｂの下端部を保持させる。
ついで、ワイヤロープ３７ｃを後部吊り環３３ｂから外してこれが巻かれたウインチを図の左方に移動させ、ワイヤロープ３７ｃをワイヤロープ３７ｂと接続して、高所作業車３８を移動させる。 Next, the wire rope 37a is wound up by the first winch, the front side 31 of the structure 30 is pulled up as shown in FIG. 11B, the structure 30 is rotated and tilted, and the wire rope 37a is fixed. To do. And the aerial work vehicle 38 is moved under the structure 30, and the lower end part of the wire rope 37b is hold | maintained.
Next, the wire rope 37c is removed from the rear suspension ring 33b, the winch around which the wire rope 37c is wound is moved to the left in the figure, the wire rope 37c is connected to the wire rope 37b, and the aerial work vehicle 38 is moved.

そして、第２のウインチによりワイヤロープ３７ｃを巻上げると共に、第１のウインチによりワイヤロープ３７ａを若干巻戻すことにより、図１１（ｃ）に示すように、構造物３０を９０°回転させて起立させる。これにより、構造物３０の吊上げ、回転作業が終了する。なお、必要に応じてクレーンやウインチを操作して吊上げられた構造物３０を所定の場所へ移動する（上記の構造物の吊上げ方法を従来技術という。なお、この従来技術が記載された刊行物はなかった）。   Then, the wire rope 37c is wound up by the second winch and the wire rope 37a is slightly rewound by the first winch, so that the structure 30 is rotated 90 ° as shown in FIG. Let Thereby, lifting of the structure 30 and rotation work are complete | finished. If necessary, the suspended structure 30 is moved to a predetermined place by operating a crane or a winch (the above-described method of lifting a structure is referred to as a conventional technique. In addition, a publication in which this conventional technique is described. There was no).

また、マスブロックの４か所にワイヤロープを掛けてクレーンで吊上げる際に、マスブロックとワイヤロープとの間に磁石を有するプロテクタを配置して、マスブロックとワイヤロープを保護するようにした技術が提案されている（例えば、特許文献１参照）。
実願昭５８−５１００２号（実開昭５９−１５６０７８号）のマイクロフイルム In addition, a protector with magnets was placed between the mass block and the wire rope to protect the mass block and the wire rope when hanging the wire rope on four places of the mass block and lifting it with a crane. A technique has been proposed (see, for example, Patent Document 1).
Microfilm of Japanese Utility Model No. 58-50002 (Japanese Utility Model Publication No. 59-1556078)

従来技術においては、構造物３０を吊上げる際に、保護部材で障害物３４を保護する必要はないが、構造物３０の吊上げ作業の途中でワイヤロープ３７ｃを後部吊り環３３ｂから外して、高所作業車３８により前部吊り環３３ａに掛けたワイヤロープ３７ｂと接続しなければならないため、きわめて面倒で作業工数が増加するばかりでなく、作業中に作業者が傾斜して吊上げた構造物３０からワイヤロープ３７ｃを外し、このワイヤロープ３７ｃを高所作業車３８上でワイヤロープ３７ｂに接続しなければならないため、危険であった。   In the prior art, when the structure 30 is lifted, it is not necessary to protect the obstacle 34 with the protective member. However, the wire rope 37c is removed from the rear suspension ring 33b in the middle of lifting the structure 30, and Since it is necessary to connect to the wire rope 37b hung on the front suspension ring 33a by the work vehicle 38, the work 30 is not only very troublesome and increases the work man-hours, but also the structure 30 that the worker inclines and lifts during the work. It is dangerous because the wire rope 37c must be removed from the wire rope 37c and connected to the wire rope 37b on the aerial work vehicle 38.

また、特許文献１に記載の技術は、マスブロックを吊上げるだけで、吊上げ作業中にマスブロックを傾動させたり回転させたりすることができないので、上記の従来技術のような構造物の吊上げ作業に適用することはできない。   Moreover, since the technique described in Patent Document 1 simply lifts the mass block and cannot tilt or rotate the mass block during the lifting work, the lifting work of the structure as in the conventional technique described above. It cannot be applied to.

本発明は、上記の課題を解決するためになされたもので、構造物に設けた障害物にワイヤロープが干渉することがなく、構造物の吊上げ、回転、起立等の作業工数を低減することができ、その上安全な構造物の吊上げ用治具及びこの吊上げ用治具を用いた構造物の吊上げ方法を提供することを目的としたものである。   The present invention has been made to solve the above-described problems, and the wire rope does not interfere with an obstacle provided in the structure, and the number of work steps such as lifting, rotating, and standing up the structure is reduced. Further, it is an object of the present invention to provide a safe structure lifting jig and a structure lifting method using the lifting jig.

本発明に係る構造物の吊上げ用治具は、頂部吊り環及び下部吊り環が設けられた胴体部と、該胴体部の一方の側又は両側に固定され、先端部にヒンジ部を介して傾動可能に受け枠が設けられた天秤とを備えたものである。   A lifting tool for a structure according to the present invention is fixed to a body portion provided with a top suspension ring and a lower suspension ring, and one side or both sides of the body portion, and tilted to the front end portion via a hinge portion. And a balance provided with a receiving frame.

上記の胴体部に固定された天秤を、下方に１０〜２０°傾斜させた。
また、上記の吊上げ用治具を所定の間隔で２基並設し、これら２基の吊上げ用治具を複数の連結部材により一体に固定した。 The balance fixed to the body part was tilted downward by 10 to 20 °.
Further, two lifting jigs are arranged side by side at a predetermined interval, and these two lifting jigs are integrally fixed by a plurality of connecting members.

本発明に係る構造物の吊上げ方法は、上記の吊上げ用治具の胴体部の上部に第１の吊上げワイヤロープを取付けると共に、該胴体部の下部にワイヤロープを取付けて該ワイヤロープの先端部を構造物の前部側下部に掛止させて前記吊上げ用治具の受け枠を前記構造物の前部側に当接させ、また第２の吊上げワイヤロープを前記構造物の後部側上部に掛止させ、前記第１の吊上げワイヤロープを巻上げて前記構造物を起立させるようにしたものである。   In the method for lifting a structure according to the present invention, the first lifting wire rope is attached to the upper portion of the body portion of the lifting jig, and the wire rope is attached to the lower portion of the body portion so that the tip portion of the wire rope is attached. Is hung on the lower part on the front side of the structure, the receiving frame of the lifting jig is brought into contact with the front part side of the structure, and the second lifting wire rope is placed on the upper part on the rear side of the structure. The structure is erected by winding and winding the first lifting wire rope.

本発明によれば、構造物の吊上げにあたって吊上げ用治具を用いることによりワイヤロープが障害物に干渉することがないので、障害物に保護部材を設ける必要がない。また、従来技術のようにワイヤロープの接続替えをする必要がないので、作業工数を大幅に低減することができ、その上吊上げ作業中に作業者が構造物の周辺に立入ることもないので、安全である。   According to the present invention, since the wire rope does not interfere with the obstacle by using the lifting jig when lifting the structure, it is not necessary to provide a protection member on the obstacle. Moreover, since it is not necessary to change the wire rope connection as in the prior art, the work man-hours can be greatly reduced, and the operator does not enter the periphery of the structure during the lifting work. , Safe.

次に、上記のように構成した吊上げ用治具１を用いて構造物１を吊上げる作業の一例を図４〜図６により説明する。なお、図１１で説明した従来技術と同じ部分にはこれと同じ符号を付し、説明を省略する。
本実施の形態においては、図１１の構造物３０の前部側３１に設けた上部吊り環３３ｃ，３３ｄは設けられていない。また、図５は構造物３０の前部側３１の正面図で、吊上げ用治具１に連結された第１の吊上げワイヤロープ２３の他端はそれぞれイコライザー天秤２５に取付けられており、イコライザー天秤２５は、クレーンに設けた第１のウインチのドラムに巻かれたワイヤロープに連結されている。 Next, an example of the operation | work which lifts the structure 1 using the lifting jig | tool 1 comprised as mentioned above is demonstrated with reference to FIGS. In addition, the same code | symbol is attached | subjected to the same part as the prior art demonstrated in FIG. 11, and description is abbreviate | omitted.
In the present embodiment, the upper suspension rings 33c and 33d provided on the front side 31 of the structure 30 in FIG. 11 are not provided. FIG. 5 is a front view of the front side 31 of the structure 30, and the other ends of the first lifting wire ropes 23 connected to the lifting jig 1 are respectively attached to an equalizer balance 25. 25 is connected to a wire rope wound around a drum of a first winch provided in the crane.

先ず、図４（ａ）に示すように、第１のウインチにより第１の吊上げワイヤロープ２３を巻戻して、これに取付けた吊上げ用治具１を障害物３４の下まで下降させる。このとき、ワイヤロープ２０に設けた玉掛けシャックル２２は、前部吊り環３３ａの近傍に位置する。そして、図４（ｂ）に示すように、玉掛けシャックル２２を前部吊り環３３ａに掛止させると、吊上げ用治具１の受け枠６ｂが構造物３０の前部側３１に当接する。
また、図６（ａ）に示すように、イコライザー天秤（図示せず）を介して第２のウインチのドラムに巻かれた第２の吊上げワイヤロープ２６の下端部を、構造物３０の後部側３２に設けた後部吊り環３３ｂに掛止させる。 First, as shown in FIG. 4A, the first lifting wire rope 23 is rewound by the first winch, and the lifting jig 1 attached thereto is lowered below the obstacle 34. At this time, the sling shackle 22 provided on the wire rope 20 is located in the vicinity of the front suspension ring 33a. Then, as shown in FIG. 4B, when the slinging shackle 22 is hooked on the front suspension ring 33 a, the receiving frame 6 b of the lifting jig 1 comes into contact with the front portion 31 of the structure 30.
6A, the lower end portion of the second lifting wire rope 26 wound around the drum of the second winch via an equalizer balance (not shown) is connected to the rear side of the structure 30. The rear suspension ring 33b provided on the second suspension ring 33 is hooked.

このとき、吊上げ用治具１の受け枠６ａ，６ｂはヒンジ８により傾動できるようになっているので、構造物３０の前部側に確実に当接する。また、吊上げ用治具１の天秤５ａ，５ｂと受け枠６ａ，６ｂの長さＬは、障害物３４の高さより長いので、第１の吊上げワイヤロープ２３が障害物３４に干渉することはない。   At this time, since the receiving frames 6 a and 6 b of the lifting jig 1 can be tilted by the hinge 8, they are surely brought into contact with the front side of the structure 30. Further, since the length L of the balances 5a and 5b and the receiving frames 6a and 6b of the lifting jig 1 is longer than the height of the obstacle 34, the first lifting wire rope 23 does not interfere with the obstacle 34. .

次に、図６（ａ）に示すように、第１、第２のウインチにより第１、第２の吊上げワイヤロープ２３，２６を若干巻上げて、構造物３０を盤木４０から浮かせる。
ついで、図６（ｂ）に示すように、後部側３２の第２の吊上げワイヤロープ２６を固定し、前部側３１の第１の吊上げワイヤロープ２３を第１のウインチで巻上げ、構造物３０の前部側３１を吊上げて傾斜（回転）させる。 Next, as shown in FIG. 6A, the first and second lifting wire ropes 23 and 26 are slightly wound up by the first and second winches, and the structure 30 is floated from the board 40.
Next, as shown in FIG. 6B, the second lifting wire rope 26 on the rear side 32 is fixed, and the first lifting wire rope 23 on the front side 31 is wound up by the first winch, and the structure 30 The front side 31 is lifted and inclined (rotated).

吊上げの当初においては、構造物３０が傾斜しても、吊上げ用治具１に荷重による負荷が作用するため、受け枠６ｂの面が構造物３０の前部側３１にバランスよく均等に当接する。また、天秤５ｂは下方にθ1°傾斜しているので、天秤５ｂの基部に作用する玉掛けワイヤロープ２４による曲げ応力を低減することができる。
構造物３０を吊上げて傾斜すると、吊上げ用治具１は構造物３０から徐々に離れ、最終的には、ワイヤロープ２０と第２の吊上げワイヤロープ２３は一直線になる。 At the beginning of lifting, even if the structure 30 is inclined, a load due to the load acts on the lifting jig 1, so that the surface of the receiving frame 6 b comes into contact with the front side 31 of the structure 30 evenly in a balanced manner. . Further, since the balance 5b is inclined downward by θ 1 °, the bending stress due to the sling wire rope 24 acting on the base of the balance 5b can be reduced.
When the structure 30 is lifted and inclined, the lifting jig 1 is gradually separated from the structure 30, and finally, the wire rope 20 and the second lifting wire rope 23 are in a straight line.

引続き第１の吊上げワイヤロープ２３を巻上げると、図６（ｃ）に示すように、構造物３０は９０°回転して起立する。このとき、第２の吊上げワイヤロープ２６は構造物３０の上端部（図の右側）に摺接する。これにより、構造物３０の吊上げ（回転）作業が終了する。なお、必要に応じて、クレーンやウインチを操作することにより、構造物３０を所望の位置に移動させることができる。   When the first lifting wire rope 23 is continuously wound up, as shown in FIG. 6 (c), the structure 30 is rotated 90 degrees to stand. At this time, the second lifting wire rope 26 comes into sliding contact with the upper end portion (right side in the drawing) of the structure 30. Thereby, the lifting (rotation) work of the structure 30 is completed. In addition, the structure 30 can be moved to a desired position by operating a crane and a winch as needed.

上記のように、本実施の形態によれば、構造物３０の吊上げにあたって吊上げ用治具１を用いることにより、ワイヤロープが障害物３４に干渉することがないので、障害物３４に保護部材を設ける必要がない。また、従来技術のように構造物３０に上部吊り環３３ｃ，３３ｄを設ける必要がないので、コストを低減できる。
さらに、従来技術のようにワイヤロープの接続替えをする必要がないので作業工数を大幅に低減することができるばかりでなく、吊上げ作業の周辺に作業者が立入ることもないので、きわめて安全である。 As described above, according to the present embodiment, since the wire rope does not interfere with the obstacle 34 by using the lifting jig 1 when lifting the structure 30, the protection member is attached to the obstacle 34. There is no need to provide it. Moreover, since it is not necessary to provide the upper suspension rings 33c and 33d in the structure 30 unlike the prior art, the cost can be reduced.
In addition, since it is not necessary to change the wire rope connection as in the prior art, not only can the work man-hours be greatly reduced, but the operator does not enter the vicinity of the lifting work, which is extremely safe. is there.
