以下、本考案の一実施形態に係る吊りピース10を図1及び図2に基づいて説明する。本実施形態に係る吊りピース10は、図1(a)に示すように、鉄骨構造材(以下、単に「鉄骨」と記載する)Fを、シャックルSを介してクレーン等のワイヤーロープWで吊り上げ、鉄骨Fを所定の施工位置に移送するために用いられる。なお、吊りピース10は鉄骨F以外の構造材を移送する際に用いることも可能である。   Hereinafter, a hanging piece 10 according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2. As shown in FIG. 1A, a suspension piece 10 according to the present embodiment lifts a steel structure member (hereinafter simply referred to as “steel frame”) F with a wire rope W such as a crane via a shackle S. , For transferring the steel frame F to a predetermined construction position. In addition, the hanging piece 10 can also be used when transferring a structural material other than the steel frame F.

図1(a)に示す如く、一対の吊りピース10・10が鉄骨Fの上面においてそれぞれ溶接により接合される。鉄骨Fに対する吊りピース10の固定位置は、適用する鉄骨Fの形状等に応じて適宜に設定可能であるが、鉄骨Fを吊り上げた状態で、鉄骨Fが縦向きにバランス良く支持されるような位置に配置することが好ましい。   As shown in FIG. 1A, a pair of hanging pieces 10 are joined to each other on the upper surface of the steel frame F by welding. The fixing position of the suspending piece 10 with respect to the steel frame F can be appropriately set according to the shape of the steel frame F to be applied. However, in a state where the steel frame F is lifted, the steel frame F is supported in a well-balanced manner in the vertical direction. It is preferable to arrange them at positions.

シャックルSは、本考案に係る係合部材の一実施形態である。シャックルSは図1(a)に示す如く、シャックルSは、U字金具と、該U字金具の先端に挿通される支持ピンと、支持ピンの軸端に形成した螺子部に締結されるナット部材と、を備えた周知の構成のものである。なお、本実施形態に係る吊りピース10において、ワイヤーロープWと連結する構成として、図1(a)に示すシャックルS以外のものを採用することも可能である。   The shackle S is an embodiment of the engagement member according to the present invention. As shown in FIG. 1A, the shackle S is a U-shaped fitting, a support pin inserted at the tip of the U-shaped fitting, and a nut member fastened to a screw formed at the shaft end of the support pin. And a known configuration having: In the hanging piece 10 according to the present embodiment, a structure other than the shackle S shown in FIG.

図1(a)及び図2(a)に示すように、吊りピース10は、溶接により鉄骨Fに固定可能な四角柱形状である固定部11と、固定部11に連結されてシャックルSと係合可能にU字形状に形成された連結部13と、を備える。図2に示す如く、固定部11は、鉄骨Fに固定される底面である固定面と、固定面の反対側に形成される上面である支持面と、を備える。なお、固定部11を円柱形状等、他の形状とすることも可能である。   As shown in FIGS. 1 (a) and 2 (a), the suspension piece 10 is connected to a fixing portion 11 having a rectangular column shape which can be fixed to the steel frame F by welding, and a shackle S connected to the fixing portion 11. And a connecting portion 13 formed in a U-shape so as to be able to be combined. As shown in FIG. 2, the fixing part 11 includes a fixing surface that is a bottom surface fixed to the steel frame F, and a support surface that is an upper surface formed on the opposite side of the fixing surface. Note that the fixing portion 11 can have another shape such as a cylindrical shape.

本実施形態に係る吊りピース10においては、四角柱である固定部11の底面における四辺を鉄骨Fに溶接する構成としている。これにより、固定部11を円柱形状に形成した場合等と比較して、鉄骨Fに固定する際の作業を容易に行うことができる。また、固定部11における支持面には、雌ねじ孔11aが開口されている。   The hanging piece 10 according to the present embodiment has a configuration in which four sides on the bottom surface of the fixing portion 11 which is a quadrangular prism are welded to the steel frame F. Thereby, compared to the case where the fixing portion 11 is formed in a cylindrical shape, the operation for fixing to the steel frame F can be easily performed. A female screw hole 11a is opened in the support surface of the fixing portion 11.

また、連結部13は雄ねじ部14aが形成されたボルト14と一体的に構成される。具体的には図2に示す如く、ボルト14は円柱形状の支持部12に貫通され、支持部12に連結部13が連結される。これにより、連結部13とボルト14とが連結される。   The connecting portion 13 is formed integrally with the bolt 14 having the male screw portion 14a. Specifically, as shown in FIG. 2, the bolt 14 is penetrated by the cylindrical support portion 12, and the connecting portion 13 is connected to the support portion 12. Thereby, the connecting portion 13 and the bolt 14 are connected.

支持部12は、基部12a及び回動部12bで構成され、回動部12bは基部12aに対して、ボルト14の周方向に回動自在に連結される。基部12aはボルト14の雄ねじ部14aを固定部11の雌ねじ孔11aに螺入することにより、固定部11に対して相対変位不能とされる。また、連結部13は回動部12bに連結される。これにより、連結部13は、固定部11の上側でボルト14の軸心回りに回動自在とされる。   The support portion 12 includes a base portion 12a and a rotating portion 12b. The rotating portion 12b is connected to the base portion 12a so as to be rotatable in the circumferential direction of the bolt 14. The base portion 12a is not displaceable relative to the fixed portion 11 by screwing the male screw portion 14a of the bolt 14 into the female screw hole 11a of the fixed portion 11. Further, the connecting portion 13 is connected to the rotating portion 12b. Thereby, the connecting portion 13 is rotatable around the axis of the bolt 14 above the fixing portion 11.

上記の如く構成することにより、連結部13は固定部11の上方において、水平方向における360度の方向の何れにも姿勢を向けることができる。即ち、鉄骨Fに対する吊りピース10の固定する方向に関わらず、ワイヤーロープWに対して連結部13を適切な姿勢とすることが可能となる。   With the above configuration, the connecting portion 13 can be oriented in any of the horizontal directions of 360 degrees above the fixing portion 11. That is, regardless of the direction in which the hanging piece 10 is fixed to the steel frame F, the connecting portion 13 can be set to an appropriate posture with respect to the wire rope W.

また、連結部13は、先端部が回動部12bに対して水平方向に挿入されることにより、ボルト14の軸心方向と直交する水平方向を回動中心として搖動可能とされる。これにより、ワイヤーロープWの引張方向に連結部13を傾けることができるため、吊りピース10の耐荷重性及び安定性を向上させることができる。   Further, the connecting portion 13 can swing about a horizontal direction orthogonal to the axial direction of the bolt 14 as a center of rotation by inserting a distal end portion of the connecting portion 13 in a horizontal direction with respect to the rotating portion 12b. Thereby, since the connecting part 13 can be inclined in the pulling direction of the wire rope W, the load resistance and the stability of the hanging piece 10 can be improved.

上記の如く構成された吊りピース10において、図2(b)に示す如く、ボルト14の雄ねじ部14aが雌ねじ孔11aに螺入される。これにより、連結部13と固定部11とが支持部12を介して連結される。   In the hanging piece 10 configured as described above, the male screw portion 14a of the bolt 14 is screwed into the female screw hole 11a as shown in FIG. Thereby, the connecting portion 13 and the fixing portion 11 are connected via the support portion 12.

本実施形態に係る吊りピース10は、上記のように連結部13と固定部11とを連結した状態で、図1(a)に示す如く鉄骨Fを所定の施工位置に移送するために用いられる。そして、使用後は、ボルト14を固定部11から取り外すことにより、図1(b)に示す如く支持部12及び連結部13を固定部11から離脱させることができる。   The hanging piece 10 according to the present embodiment is used for transferring the steel frame F to a predetermined construction position as shown in FIG. 1A in a state where the connecting portion 13 and the fixing portion 11 are connected as described above. . After use, the support portion 12 and the connecting portion 13 can be detached from the fixing portion 11 by removing the bolt 14 from the fixing portion 11 as shown in FIG.

このように、本実施形態に係る吊りピース10は、鉄骨Fを移送した後で支持部12及び連結部13を固定部11から取り外すことにより、鉄骨Fには固定部11のみを残すことができる。このため、鉄骨Fに対して後付けされる他の構造材と、支持部12及び連結部13とが干渉することがない。即ち、吊りピース10の切除等が不要となるため、現場における作業負担を低減させることが可能となる。   As described above, the hanging piece 10 according to the present embodiment can leave only the fixing portion 11 on the steel frame F by removing the support portion 12 and the connecting portion 13 from the fixing portion 11 after transferring the steel frame F. . For this reason, there is no interference between the support portion 12 and the connecting portion 13 with another structural material to be retrofitted to the steel frame F. That is, it is not necessary to cut off the hanging pieces 10 and the like, so that the work load on the site can be reduced.

また、本実施形態に係る吊りピース10は、固定部11、支持部12、及び、連結部13を、想定される荷重に対して耐えうる大きさで形成することができる。このため、吊りピース10に対してシャックルSの組付作業性を確保することができる。さらに、吊りピース10における固定部11の溶接強度や、シャックルSとの係合強度が低下することがない。このように、本考案に係る吊りピース10によれば、シャックルSとの組付作業性の悪化や溶接強度及び係合強度の低下を招くことなく、現場での作業負担を減少させることが可能となるのである。   Further, in the hanging piece 10 according to the present embodiment, the fixing portion 11, the support portion 12, and the connecting portion 13 can be formed in a size that can withstand an assumed load. Therefore, the workability of assembling the shackle S with respect to the hanging piece 10 can be ensured. Further, the welding strength of the fixing portion 11 of the suspension piece 10 and the strength of engagement with the shackle S do not decrease. As described above, according to the hanging piece 10 according to the present invention, it is possible to reduce the work load on the site without inducing the workability of assembling with the shackle S and reducing the welding strength and the engagement strength.
