Description

本考案は、建築現場等において柱用又は梁用として採用される鉄骨構造材を吊り上げる際に用いられる吊りピースに関する。 The present invention relates to a suspending piece used for lifting a steel structural material used for a pillar or a beam at a building site or the like.

従来、建築現場において鉄骨構造材を所定の施工位置へ移送するため、これらの鉄骨構造材に吊りピースを溶接固定し、この吊りピースの挿通孔にシャックル等の連結部材を介してワイヤーロープを連係し、クレーンにてワイヤーロープ、シャックル、及び、吊りピースを介して鉄骨構造材を吊り上げる技術が用いられている（例えば、特許文献１を参照）。 Conventionally, in order to transfer steel structure materials to a predetermined construction position at a construction site, hanging pieces are welded and fixed to these steel structure materials, and wire ropes are connected to the insertion holes of the hanging pieces via connecting members such as shackles. In addition, a technique is used in which a steel frame material is lifted by a crane via a wire rope, a shackle, and a hanging piece (for example, see Patent Document 1).

上記の如く鉄骨構造材を移送した後に、鉄骨構造材に対して後付けされる他の構造材と吊りピースとが干渉することがある。この場合、鉄骨構造材に固定した吊りピースの切除が必要となるため、現場における作業負担増の要因となっていた。一方、吊りピースの寸法を小さくして、他の構造材との干渉を防ぐ構成とした場合、吊りピースに対するシャックルの組付作業性の悪化や、吊りピースの溶接強度やシャックルとの係合強度の低下に繋がっていた。 After transferring the steel structure material as described above, there may be a case where the suspension piece interferes with another structure material attached to the steel structure material. In this case, it is necessary to cut off the suspension pieces fixed to the steel structural member, which has been a factor of increasing the work load on the site. On the other hand, if the dimensions of the suspending piece are reduced to prevent interference with other structural materials, the workability of assembling the shackle to the suspending piece, the welding strength of the suspending piece and the engaging strength with the shackle Has been reduced.

本考案は、上述の課題に鑑みてなされたものであり、シャックル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、吊りピースを提供することを目的としている。 The present invention has been made in view of the above-described problem, and it is possible to reduce the work load on the site without inviting a decrease in workability in assembling with a shackle and a decrease in welding strength and engagement strength.

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. It becomes.
