Description

本発明は、外壁パネル等の建材を吊り上げる際に用いられる吊り具に関するものである。 The present invention relates to a hanging tool used for lifting a building material such as an outer wall panel.

建築現場において建物を構築する際には、外壁パネルや屋根パネル等の建材をクレーンにより吊り上げて建物躯体における所定の取付位置に移動させる作業が行われることがある。このような移動作業において、建材を吊り上げる際には、専用の吊り具が用いられることが多い。吊り具は建材に対して取り付けられ、その吊り具にはクレーンのフックが取り付けられる。そして、そのような吊り具の取付状態で、クレーンにより建材が吊り具を介して吊り上げられるようになっている。 When constructing a building at a construction site, a work may be performed in which building materials such as outer wall panels and roof panels are lifted by a crane and moved to a predetermined mounting position on the building frame. In such moving work, when lifting building materials, a dedicated hanging tool is often used. The hanger is attached to the building material, and the hook of the crane is attached to the hanger. Then, with such a hanging tool attached, the building material is lifted by the crane via the hanging tool.

特許文献1には、かかる吊り具が開示されている。以下では、この吊り具の構成について図4に基づき説明する。図4に示すように、特許文献1の吊り具40は、一対の吊り具本体41を備え、それら各吊り具本体41は、軸部42と、その軸部42の一端側に設けられた吊り部43と、軸部42の他端側に設けられた係止部44とをそれぞれ有している。吊り部43は、軸部42と交差する方向に突出しており、環状をなしている。また、係止部44は、軸部42と交差する方向に突出しており、その突出方向が吊り部43の突出方向と交差する方向となっている。 Patent Document 1 discloses such a hanging tool. Hereinafter, the configuration of the hanging tool will be described with reference to FIG. As shown in FIG. 4, the hanging tool 40 of Patent Document 1 includes a pair of hanging tool main bodies 41, and each of the hanging tool main bodies 41 is provided with a shaft portion 42 and one end side of the shaft portion 42. It has a portion 43 and a locking portion 44 provided on the other end side of the shaft portion 42, respectively. The suspension portion 43 projects in a direction intersecting the shaft portion 42 and forms an annular shape. Further, the locking portion 44 projects in a direction intersecting the shaft portion 42, and the protruding direction thereof intersects with the projecting direction of the suspension portion 43.

各吊り具本体41において、各々の軸部42は同じ方向に延びる向きで並設されている。また、各々の吊り部43は各軸部42に対して一方側に配置され、各々の係止部44は各軸部42に対して他方側に配置されている。そして、各吊り具本体41は、かかる配置状態で連結具47により互いに連結されている。この連結状態において、各吊り具本体41は各々の軸部42を中心として互いに回動可能とされている。各吊り具本体41の回動により、各吊り部43は互いに反対側に突出する開状態(図4(a)の状態)と、互いに同じ側に突出する閉状態(図4(b)の状態)とに開閉可能となっている。そして、各吊り部43が開状態とされると各係止部44が同じ側に突出する閉状態(図4(a)の状態)となり、各吊り部43が閉状態とされると各係止部44が互いに反対側に突出する開状態(図4(b)の状態)となるようになっている。 In each hanger body 41, the shaft portions 42 are arranged side by side in a direction extending in the same direction. Further, each suspension portion 43 is arranged on one side with respect to each shaft portion 42, and each locking portion 44 is arranged on the other side with respect to each shaft portion 42. Then, the hanging tool main bodies 41 are connected to each other by the connecting tool 47 in such an arrangement state. In this connected state, the hanger main bodies 41 are rotatable about each other about the shaft portion 42. Due to the rotation of each hanging tool main body 41, each hanging portion 43 is in an open state (state in FIG. 4A) protruding to the opposite side and a closed state (state in FIG. 4B) protruding in the same side. ) And can be opened and closed. Then, when each hanging portion 43 is opened, each locking portion 44 is in a closed state (state in FIG. 4A) protruding to the same side, and when each hanging portion 43 is in a closed state, each engaging portion is engaged. The stop portions 44 are in an open state (state in FIG. 4B) protruding to the opposite sides from each other.

続いて、上記の吊り具40を用いてクレーンにより建材としての外壁パネルを吊り上げる際の作業手順について説明する。図5(a)に示すように、外壁パネル50は、外壁面材51と、その裏面側に設けられた外壁フレーム52とを備えて構成されている。外壁パネル50は、パレットの上等にあらかじめ寝かせた状態で置かれている。 Subsequently, a work procedure for lifting the outer wall panel as a building material by a crane using the above-mentioned hanger 40 will be described. As shown in FIG. 5A, the outer wall panel 50 includes an outer wall surface material 51 and an outer wall frame 52 provided on the back surface side thereof. The outer wall panel 50 is laid down on a pallet or the like in advance.

外壁パネル50の吊り上げ作業に際してはまず吊り具40を外壁パネル50の外壁フレーム52に取り付ける作業を行う。この作業では、吊り具40の各係止部44を閉状態とし(図4(a)参照)、その状態で各係止部44を外壁フレーム52の上端部に形成された挿通孔55に挿通する。挿通後、各吊り部43を閉状態として各係止部44を開状態とする(図4(b)参照)。これにより、各係止部44が外壁フレーム52に係止される状態となり、その結果、吊り具40が外壁パネル50に対して横向きの状態(寝かせた状態)で取り付けられる。また、図5の例では、吊り具40が各吊り部43を下方に向けた状態で外壁パネル50に取り付けられている。 When lifting the outer wall panel 50, first, the hanging tool 40 is attached to the outer wall frame 52 of the outer wall panel 50. In this work, each locking portion 44 of the hanging tool 40 is closed (see FIG. 4A), and in that state, each locking portion 44 is inserted into an insertion hole 55 formed at the upper end of the outer wall frame 52. To do. After the insertion, each hanging portion 43 is closed and each locking portion 44 is opened (see FIG. 4B). As a result, each of the locking portions 44 is locked to the outer wall frame 52, and as a result, the hanger 40 is attached to the outer wall panel 50 in a sideways state (laid down). Further, in the example of FIG. 5, the hanging tool 40 is attached to the outer wall panel 50 with each hanging portion 43 facing downward.

その後、閉状態にある各吊り部43の内側にクレーンのフックFをまとめて挿通する。これにより、クレーンにより外壁パネル50を吊り具40を介して吊り上げ可能な状態となる。また、フックFが各吊り部43内に挿通されることで、フックFにより各吊り部43が開くことが規制されるため、各係止部44が開状態に維持されることになる。以上により、吊り上げ前の準備作業が完了する。 After that, the hooks F of the crane are collectively inserted into each of the suspended portions 43 in the closed state. As a result, the outer wall panel 50 can be lifted by the crane via the hanger 40. Further, since the hook F is inserted into each suspension portion 43, the hook F restricts the opening of each suspension portion 43, so that each locking portion 44 is maintained in the open state. With the above, the preparatory work before lifting is completed.

準備作業を終えた後は、クレーンにより外壁パネル50を吊り上げる作業を行う。吊り上げに際しては、まずクレーンにより吊り具40が引き上げられる。この引き上げにより、吊り具40は、図5(b)に示すように、横向きの状態から斜めの状態へと移行する。そして、吊り具40がある状態まで立ち上がると、外壁パネル50がパレット上から引き上げられ、その後さらに引き上げられると、外壁パネル50が縦向きの状態で吊り上げられる。 After the preparatory work is completed, the work of lifting the outer wall panel 50 by a crane is performed. At the time of lifting, the lifting tool 40 is first pulled up by a crane. By this pulling, the hanger 40 shifts from the sideways state to the slanted state as shown in FIG. 5 (b). Then, when the hanger 40 is raised to a certain state, the outer wall panel 50 is pulled up from the pallet, and when the hanger 40 is further pulled up, the outer wall panel 50 is lifted in a vertical direction.

ところで、上記特許文献1の吊り具40は、各吊り部43がフックFを引っ掛けるためだけでなく、各吊り部43を開閉操作する際の操作部としても用いられる。このため、各吊り部43は、開閉操作をし易くするため、ある程度の大きさを有して形成される必要がある。 By the way, the hanging tool 40 of Patent Document 1 is used not only for each hanging portion 43 to hook the hook F, but also as an operating portion for opening and closing each hanging portion 43. Therefore, each hanging portion 43 needs to have a certain size in order to facilitate the opening / closing operation.

その一方で、各吊り部43の大きさが大きいと、各吊り部43の内側にフックFを通して外壁パネル50を吊り上げる際、その吊り上げる過程でフックFが吊り部43内において大きく変位(移動)することが想定される。その場合、図5(b)に示すように、吊り部43内でのフックFの変位に伴い、意図せず各吊り部43が開く方向の力が生じて、各吊り部43が開いてしまうことが想定される。その場合、各係止部44が閉状態となって外壁フレーム52の挿通孔55から抜け落ち、それにより吊り具40が外壁パネル50から外れてしまうおそれがある。 On the other hand, if the size of each hanging portion 43 is large, when the outer wall panel 50 is lifted through the hook F inside each hanging portion 43, the hook F is largely displaced (moved) in the hanging portion 43 in the lifting process. Is assumed. In that case, as shown in FIG. 5B, due to the displacement of the hook F in the suspension portion 43, a force in the direction in which each suspension portion 43 is unintentionally opened is generated, and each suspension portion 43 is opened. Is assumed. In that case, each locking portion 44 may be closed and fall out of the insertion hole 55 of the outer wall frame 52, whereby the hanger 40 may come off from the outer wall panel 50.

本発明は、上記事情に鑑みてなされたものであり、建材を吊り上げる吊り上げ過程において、建材から外れてしまうのを防止することができる吊り具を提供することを主たる目的とするものである。 The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a hanging tool capable of preventing the building material from coming off in the process of lifting the building material.

各吊り具本体11A,11Bにおいて、各々の軸部12A,12Bは同じ方向に延びる向きで並設されている。つまり、各軸部12A,12Bは互いに平行な状態で隣接配置されている。また、各吊り具本体11A,11Bにおいて、各々の吊り部13A,13Bは各軸部12A,12Bに対して(同じ)一方側に配置され、各々の係止部14A,14Bは各軸部12A,12Bに対して(同じ)他方側に配置されている。 In the hanger main bodies 11A and 11B, the shaft portions 12A and 12B are arranged side by side in a direction extending in the same direction. That is, the shaft portions 12A and 12B are arranged adjacent to each other in a state of being parallel to each other. Further, in each of the hanging tool main bodies 11A and 11B, the respective hanging portions 13A and 13B are arranged on one side (same) with respect to the respective shaft portions 12A and 12B, and the respective locking portions 14A and 14B are the respective shaft portions 12A. , 12B is located on the other side (same).

各吊り具本体11A,11Bは、各々の軸部12A,12Bが連結具17により互いに連結されている。連結具17は、ゴム材料により筒状に形成され、各軸部12A,12Bをまとめて囲んだ状態で設けられている。 The shaft portions 12A and 12B of the hanger main bodies 11A and 11B are connected to each other by the connector 17. The connector 17 is formed of a rubber material in a tubular shape, and is provided in a state of enclosing the shaft portions 12A and 12B together.

各吊り具本体11A,11Bは、各々の軸部12A,12Bを回動中心として互いに回動可能とされている。各吊り具本体11A,11Bの回動により、各吊り部13A,13Bは、互いに反対側に突出する開状態(図1(a)及び図2(a)の状態)と、互いに同じ側に突出する閉状態(図1(b)及び図2(b)の状態)とに開閉可能となっている。各吊り部13A,13Bは、閉状態では互いに向き合うように配置され、各々の開口部(孔部)が互いに連通された状態となる。そのため、各吊り部13A,13Bの閉状態においては、各吊り部13A,13BにクレーンのフックFをまとめて挿通することが可能となっている。 The hanger main bodies 11A and 11B are rotatable about each of the shaft portions 12A and 12B. Due to the rotation of the hanging tool main bodies 11A and 11B, the hanging portions 13A and 13B are projected to the same side as the open state (states of FIGS. 1A and 2A) protruding to the opposite sides. It can be opened and closed in the closed state (states of FIGS. 1 (b) and 2 (b)). The hanging portions 13A and 13B are arranged so as to face each other in the closed state, and the respective openings (holes) are in a state of being communicated with each other. Therefore, in the closed state of the suspension portions 13A and 13B, the hooks F of the crane can be collectively inserted into the suspension portions 13A and 13B.

各吊り具本体11A,11Bでは、各吊り部13A,13Bが開状態とされると各係止部14A,14Bが同じ側に突出する閉状態(図1(a)及び図2(a)の状態)とされ、各吊り部13A,13Bが閉状態とされると各係止部14A,14Bが互いに反対側に突出する開状態(図1(b)及び図2(b)の状態)とされる。したがって、本吊り具10では、各吊り部13A,13Bが開閉操作されることで、各係止部14A,14Bが開閉動作されるようになっている。この場合、各吊り部13A,13Bは、フックFが引っ掛けられる引掛部としての役割に加え、開閉操作に際し把持される操作部としての役割も有している。 In the hanging tool main bodies 11A and 11B, when the hanging portions 13A and 13B are opened, the locking portions 14A and 14B are in the closed state (in FIGS. 1A and 2A). When the hanging portions 13A and 13B are closed, the locking portions 14A and 14B are in an open state (states of FIGS. 1B and 2B) in which the locking portions 14A and 14B project to opposite sides. Will be done. Therefore, in the hanging tool 10, the locking portions 14A and 14B are opened and closed by opening and closing the hanging portions 13A and 13B. In this case, the hanging portions 13A and 13B have a role as a hooking portion on which the hook F is hooked and also as an operating portion to be gripped during the opening / closing operation.

ここで、本実施形態の吊り具10には、各吊り部13A,13B内にクレーンのフックFが挿通された状態で、そのフックFについて吊り部13A,13B内での変位を規制する規制部が設けられている。以下、この規制部に関する構成について説明する。 Here, in the suspension tool 10 of the present embodiment, with the hook F of the crane inserted in the suspension portions 13A and 13B, the regulation unit that regulates the displacement of the hook F in the suspension portions 13A and 13B. Is provided. The configuration of this regulatory unit will be described below.

各吊り具本体11A,11Bの吊り部13A,13Bにはそれぞれ規制部としての環状部19A,19Bが設けられている。環状部19A,19Bは金属製のリング部材であり、円環状をなしている。環状部19A,19Bは、その大きさが吊り部13A,13Bよりも小さくなっており、詳しくは、その外径が吊り部13A,13Bの突出方向における吊り部13A,13Bの長さよりも小さく、かつ、その突出方向と直交する方向(換言すると軸部12A,12Bの軸線方向)における吊り部13A,13Bの長さよりも小さくなっている。本実施形態では、環状部19A,19Bの外径が吊り部13A,13Bの突出方向の長さの半分以下となっている。 The hanging portions 13A and 13B of the hanging tool main bodies 11A and 11B are provided with annular portions 19A and 19B as regulating portions, respectively. The annular portions 19A and 19B are metal ring members and form an annular shape. The size of the annular portions 19A and 19B is smaller than that of the suspension portions 13A and 13B, and more specifically, the outer diameter thereof is smaller than the length of the suspension portions 13A and 13B in the projecting direction of the suspension portions 13A and 13B. Moreover, it is smaller than the lengths of the hanging portions 13A and 13B in the direction orthogonal to the protruding direction (in other words, the axial direction of the shaft portions 12A and 12B). In the present embodiment, the outer diameters of the annular portions 19A and 19B are less than half the length of the suspension portions 13A and 13B in the protruding direction.

環状部19A,19Bは、その開口部(孔部)を吊り部13A,13Bの開口部(孔部)と同じ方向(以下、開口方向という)に向けた状態で吊り部13A,13Bに固定されている。環状部19A,19Bは、上記開口方向において吊り部13A,13Bと重なり合っており、その状態で吊り部13A,13Bに溶接により固定されている。詳しくは、環状部19A,19Bは、吊り部13A,13Bの閉状態において、吊り部13A,13Bの外側に位置するよう配置されている。 The annular portions 19A and 19B are fixed to the suspension portions 13A and 13B with their openings (holes) facing in the same direction as the openings (holes) of the suspension portions 13A and 13B (hereinafter referred to as the opening direction). ing. The annular portions 19A and 19B overlap with the suspension portions 13A and 13B in the opening direction, and are fixed to the suspension portions 13A and 13B by welding in that state. Specifically, the annular portions 19A and 19B are arranged so as to be located outside the suspension portions 13A and 13B in the closed state of the suspension portions 13A and 13B.

各環状部19A,19Bは、上記開口方向から見て吊り部13A,13Bの内側に位置するように配置されている。この場合、各環状部19A,19Bは、その外周側が吊り部13A,13Bからはみ出ないように配置されている。また、各環状部19A,19Bは、吊り部13A,13Bにおいて、吊り部13A,13Bの突出方向における先端側に配置されている。詳しくは、各環状部19A,19Bは、その全体が吊り部13A,13Bの突出方向における中央部よりも先端側に位置するよう配置されている。また、各環状部19A,19Bは、吊り部13A,13Bにおいて、上記突出方向と直交する方向(軸部12A,12Bの軸線方向)における係止部14A,14B側とは反対側に配置されている。 The annular portions 19A and 19B are arranged so as to be located inside the suspension portions 13A and 13B when viewed from the opening direction. In this case, the annular portions 19A and 19B are arranged so that their outer peripheral sides do not protrude from the suspension portions 13A and 13B. Further, the annular portions 19A and 19B are arranged on the tip side of the suspension portions 13A and 13B in the protruding direction of the suspension portions 13A and 13B. Specifically, the annular portions 19A and 19B are arranged so that the entire annular portion 19A and 19B is located closer to the tip end side than the central portion in the protruding direction of the suspension portions 13A and 13B. Further, the annular portions 19A and 19B are arranged on the suspension portions 13A and 13B on the opposite sides of the locking portions 14A and 14B in the direction orthogonal to the protruding direction (the axial direction of the shaft portions 12A and 12B). There is.

各環状部19A,19Bは、各吊り部13A,13Bの閉状態において各吊り部13A,13Bを挟んで対向配置される。つまり、各環状部19A,19Bは、各吊り部13A,13Bの閉状態においては、上記開口方向から見て同じ位置に配置される。この場合、各環状部19A,19Bの開口部と各吊り部13A,13Bの開口部とは上記開口方向に連通し、その連通部を通じてフックFを挿通することが可能となっている。 The annular portions 19A and 19B are arranged so as to face each other with the suspension portions 13A and 13B interposed therebetween in the closed state of the suspension portions 13A and 13B. That is, the annular portions 19A and 19B are arranged at the same positions when viewed from the opening direction in the closed state of the suspension portions 13A and 13B. In this case, the openings of the annular portions 19A and 19B and the openings of the suspension portions 13A and 13B communicate with each other in the opening direction, and the hook F can be inserted through the communicating portions.

次に、上述した吊り具10の使用方法について説明する。ここでは、建材としての外壁パネル30をクレーンにより吊り上げる際に、吊り具10を用いて吊り上げることを想定している。図3は、吊り具10を用いて外壁パネル30を吊り上げる際の様子を示す図であり、以下では、この図3を参照しながら説明を行う。 Next, a method of using the above-mentioned hanger 10 will be described. Here, it is assumed that when the outer wall panel 30 as a building material is lifted by a crane, it is lifted by using a hanging tool 10. FIG. 3 is a diagram showing a state in which the outer wall panel 30 is lifted by using the hanging tool 10, and will be described below with reference to FIG.

図3に示すように、外壁パネル30はパレットPの上に寝かせた状態で置かれている。外壁パネル30は、外壁面材31と、外壁面材31の裏面側に設けられた外壁フレーム32とを有している。外壁面材31は、窯業系サイディングボードにより形成されている。外壁フレーム32は、複数のフレーム材33が矩形枠状に組まれることにより形成されている。各フレーム材33は断面コ字状の軽量溝形鋼からなり、その溝部をフレーム内側に向けて配設されている。各フレーム材33のうち、外壁フレーム32の上端部に配置された上端フレーム材33aは横方向に延びており、その上端フレーム材33a(詳しくはそのウェブ)には吊り具10の係止部14A,14Bを挿通可能な挿通孔36が形成されている。挿通孔36は、上端フレーム材33aの長手方向に複数(例えば2つ)形成されている。 As shown in FIG. 3, the outer wall panel 30 is laid down on the pallet P. The outer wall panel 30 has an outer wall surface material 31 and an outer wall frame 32 provided on the back surface side of the outer wall surface material 31. The outer wall surface material 31 is formed of a ceramic siding board. The outer wall frame 32 is formed by assembling a plurality of frame members 33 into a rectangular frame shape. Each frame material 33 is made of lightweight channel steel having a U-shaped cross section, and the groove portion is arranged toward the inside of the frame. Of the frame materials 33, the upper end frame material 33a arranged at the upper end of the outer wall frame 32 extends in the lateral direction, and the upper end frame material 33a (specifically, the web) has a locking portion 14A of the hanger 10. , 14B is formed with an insertion hole 36 through which the insertion hole 36 can be inserted. A plurality (for example, two) of the insertion holes 36 are formed in the longitudinal direction of the upper end frame member 33a.

外壁パネル30を吊り具10を用いて吊り上げる際には、まず吊り具10を外壁パネル30の上端フレーム材33aに取り付ける作業を行う。この場合、吊り具10を横向きに寝かせた状態で上端フレーム材33aに取り付ける。具体的には、吊り具10を、各吊り部13A,13Bが下方を向く状態で上端フレーム材33aに取り付ける。 When the outer wall panel 30 is lifted by using the hanging tool 10, the hanging tool 10 is first attached to the upper end frame material 33a of the outer wall panel 30. In this case, the hanger 10 is attached to the upper end frame material 33a in a state of being laid sideways. Specifically, the hanging tool 10 is attached to the upper end frame material 33a with the hanging portions 13A and 13B facing downward.

吊り具10を上端フレーム材33aに取り付ける際には、各係止部14A,14Bを閉状態とし、その状態で各係止部14A,14Bを上端フレーム材33aの挿通孔36に挿通する。挿通後、各吊り部13A,13Bを閉状態として各係止部14A,14Bを開状態とする。これにより、各係止部14A,14Bが上端フレーム材33aに係止される状態となり、その結果、吊り具10が外壁パネル30に対して横向きの状態で取り付けられる。なお、吊り具10は、各挿通孔36ごとに複数取り付けられる。 When the hanger 10 is attached to the upper end frame member 33a, the locking portions 14A and 14B are closed, and in that state, the locking portions 14A and 14B are inserted into the insertion holes 36 of the upper end frame member 33a. After the insertion, the hanging portions 13A and 13B are closed and the locking portions 14A and 14B are opened. As a result, the locking portions 14A and 14B are locked to the upper end frame member 33a, and as a result, the hanger 10 is attached sideways to the outer wall panel 30. A plurality of hanging tools 10 are attached to each insertion hole 36.

続いて、閉状態の各吊り部13A,13Bの内側にクレーンのフックFを挿通する作業を行う。この作業では、各吊り部13A,13Bの内側と各環状部19A,19Bの内側とにそれぞれフックFをまとめて挿通する。これにより、各吊り部13A,13B(及び各環状部19A,19B)にフックFを引っ掛け可能な状態とされる。以上により、外壁パネル30の吊り上げ前の準備作業が終了する。なお、フックFは、例えばカラビナからなる。但し、フックFは必ずしもカラビナである必要はなく、シャックル等、他のフックであってもよい。 Subsequently, the work of inserting the hook F of the crane into the inside of the suspended portions 13A and 13B in the closed state is performed. In this work, the hooks F are collectively inserted into the inside of the hanging portions 13A and 13B and the inside of the annular portions 19A and 19B, respectively. As a result, the hook F can be hooked on the hanging portions 13A and 13B (and the annular portions 19A and 19B). With the above, the preparatory work before lifting the outer wall panel 30 is completed. The hook F is made of, for example, a carabiner. However, the hook F does not necessarily have to be a carabiner, and may be another hook such as a shackle.

続いて、クレーンにより外壁パネル30を吊り具10を介して吊り上げる作業を行う。この吊り上げ作業ではまず、吊り具10がクレーンにより上方へ引き上げられる。すると、それに伴い、吊り具10が横向きの状態から斜めの状態へと移行する。吊り具10がある状態まで立ち上がると外壁パネル30がパレットP上から引き上げられる。そして、さらなる引き上げが行われることで、外壁パネル30が縦向きの状態で吊り上げられる。 Subsequently, a crane is used to lift the outer wall panel 30 via the hanging tool 10. In this lifting operation, the lifting tool 10 is first pulled upward by a crane. Then, along with this, the hanger 10 shifts from the sideways state to the oblique state. When the hanger 10 stands up to a certain state, the outer wall panel 30 is pulled up from the pallet P. Then, by further pulling up, the outer wall panel 30 is lifted in a vertically oriented state.

ここで、本吊り具10では、フックFが各環状部19A,19Bに挿通されているため、それら環状部19A,19BによりフックFが吊り部13A,13B内において変位することが規制されている。この場合、外壁パネル30を吊り上げる吊り上げ過程において、フックFが吊り部13A,13B内で大きく変位するのを規制することができるため、フックFの変位に伴い意図せず各吊り部13A,13Bが開く方向の力が発生するのを防止することができる。そのため、外壁パネル30の吊り上げ過程で、各吊り部13A,13Bが開いて各係止部14A,14Bが閉状態となるのを防止することができ、その結果、吊り具10が外壁パネル30から外れてしまうのを防止することができる。 Here, in the present hanger 10, since the hook F is inserted through the annular portions 19A and 19B, the hook F is restricted from being displaced in the suspension portions 13A and 13B by the annular portions 19A and 19B. .. In this case, in the lifting process of lifting the outer wall panel 30, it is possible to restrict the hook F from being largely displaced in the hanging portions 13A and 13B, so that the hanging portions 13A and 13B unintentionally move due to the displacement of the hook F. It is possible to prevent the generation of a force in the opening direction. Therefore, it is possible to prevent the hanging portions 13A and 13B from opening and the locking portions 14A and 14B from being closed in the process of lifting the outer wall panel 30, and as a result, the hanging tool 10 is released from the outer wall panel 30. It can be prevented from coming off.

以上、詳述した本実施形態の構成によれば、以下の優れた効果が得られる。 According to the configuration of the present embodiment described in detail above, the following excellent effects can be obtained.

規制部として、吊り部13A,13Bよりも小さい環状をなす環状部19A,19Bを設け、その環状部19A,19Bを吊り部13A,13Bの内側に位置するようにして当該吊り部13A,13Bに固定した。この場合、各吊り部13A,13BにフックFを挿通させる際に、各環状部19A,19BにもフックFを挿通させることが可能となる。このため、各吊り部13A,13B内でのフックFの変位を環状部19A,19Bにより規制することができる。また、この場合、規制部が環状部19A,19Bとなっていることで、フックFを挿通させる位置がわかり易く、フックFの挿通作業を好適に行うことが可能となる。 An annular portions 19A and 19B that are smaller than the suspension portions 13A and 13B are provided as regulating portions, and the annular portions 19A and 19B are located inside the suspension portions 13A and 13B so as to be located inside the suspension portions 13A and 13B. Fixed. In this case, when the hook F is inserted through the hanging portions 13A and 13B, the hook F can also be inserted through the annular portions 19A and 19B. Therefore, the displacement of the hook F in each of the hanging portions 13A and 13B can be regulated by the annular portions 19A and 19B. Further, in this case, since the restricting portions are the annular portions 19A and 19B, the position where the hook F is inserted is easy to understand, and the hook F insertion work can be preferably performed.

具体的には、各吊り部13A,13Bにそれぞれ環状部19A,19Bを設け、それら各環状部19A,19Bが各吊り部13A,13Bの閉状態において互いに対向配置されるようにした。この場合、各吊り部13A,13BにフックFが挿通される際には各環状部19A,19BにもそれぞれフックFが挿通される。このため、各吊り部13A,13B内でのフックFの変位を好適に規制することができる。また、この場合、フックFを各吊り部13A,13Bのいずれの側から吊り部13A,13Bに挿通する際にもフックFを挿通させる位置がわかり易いため、フックFの挿通作業をより一層好適に行うことができる。 Specifically, the annular portions 19A and 19B are provided on the suspension portions 13A and 13B, respectively, and the annular portions 19A and 19B are arranged so as to face each other in the closed state of the suspension portions 13A and 13B. In this case, when the hook F is inserted through the hanging portions 13A and 13B, the hook F is also inserted through the annular portions 19A and 19B, respectively. Therefore, the displacement of the hook F in each of the hanging portions 13A and 13B can be suitably regulated. Further, in this case, when the hook F is inserted into the hanging portions 13A and 13B from any side of the hanging portions 13A and 13B, the position where the hook F is inserted is easy to understand, so that the insertion work of the hook F is more preferably performed. It can be carried out.

環状部19A,19Bを、吊り部13A,13Bにおいて吊り部13A,13Bの突出方向の先端側に配置したため、フックFが吊り部13A,13B内において上記先端側から基端側へ変位することを規制することができる。この場合、各吊り部13A,13Bが回動して開く際の回動先端側で各吊り部13A,13BがフックFにより連結された状態となるため、各吊り部13A,13Bが開いてしまうのを好適に防止することができる。そのため、吊り具10が外壁パネル30から外れてしまうのを好適に防止することができる。 Since the annular portions 19A and 19B are arranged on the tip side of the suspension portions 13A and 13B in the protruding direction of the suspension portions 13A and 13B, the hook F is displaced from the tip end side to the base end side in the suspension portions 13A and 13B. Can be regulated. In this case, since the hanging portions 13A and 13B are connected by the hook F on the rotation tip side when the hanging portions 13A and 13B rotate and open, the hanging portions 13A and 13B open. Can be suitably prevented. Therefore, it is possible to preferably prevent the hanging tool 10 from coming off from the outer wall panel 30.

本発明は上記実施形態に限らず、例えば次のように実施されてもよい。 The present invention is not limited to the above embodiment, and may be implemented as follows, for example.

・上記実施形態では、各吊り部13A,13Bにそれぞれ環状部19A,19Bを設けたが、各吊り部13A,13Bのうちいずれか一方の吊り部13A(又は13B)にのみ環状部19A(又は19B)を設けるようにしてもよい。この場合にも、その環状部19A(又は19B)にフックFを挿通することで、吊り部13A,13B内でのフックFの変位を規制することができる。 -In the above embodiment, the annular portions 19A and 19B are provided on the suspension portions 13A and 13B, respectively, but the annular portion 19A (or 13B) is provided only on the suspension portion 13A (or 13B) of either of the suspension portions 13A and 13B. 19B) may be provided. Also in this case, the displacement of the hook F in the hanging portions 13A and 13B can be regulated by inserting the hook F into the annular portion 19A (or 19B).

・上記実施形態では、環状部19A,19B(規制部に相当)により、各吊り部13A,13B内でのフックFの変位を規制するようにしたが、フックFの変位を規制する規制部は必ずしも環状部19A,19Bにより形成する必要はない。例えば、吊り部13A,13Bに、規制部として、吊り部13A,13Bの開口部を区画する棒材からなる区画部を設けることが考えられる。この場合、吊り部13A,13Bの開口部において区画部により区画された複数の領域のうちいずれか一方の領域をフックFの挿通領域とし、その挿通領域にフックFを挿通することでフックFの変位を規制することが考えられる。 -In the above embodiment, the annular portions 19A and 19B (corresponding to the regulating portions) regulate the displacement of the hook F in each of the hanging portions 13A and 13B, but the regulating portion that regulates the displacement of the hook F is It does not necessarily have to be formed by the annular portions 19A and 19B. For example, it is conceivable to provide the suspension portions 13A and 13B with a partition portion made of a bar for partitioning the openings of the suspension portions 13A and 13B as a regulation portion. In this case, one of a plurality of regions partitioned by the compartments at the openings of the suspension portions 13A and 13B is used as the insertion region of the hook F, and the hook F is inserted into the insertion region of the hook F. It is conceivable to regulate the displacement.

・上記実施形態では、寝かせた状態(横向き状態)の外壁パネル30を吊り具10を用いて吊り上げる場合について説明したが、外壁パネル30が架台等に入れられて縦向きの状態で保管されている際には、その縦向きの外壁パネル30を吊り具10を用いて吊り上げるようにしてもよい。かかる場合には、外壁パネル30の上端フレーム材33aに縦向きに吊り具10を取り付け、その取付状態で外壁パネル30を吊り上げることになる。 -In the above embodiment, the case where the outer wall panel 30 in the laid state (horizontal orientation state) is lifted by using the hanging tool 10 has been described, but the outer wall panel 30 is put in a pedestal or the like and stored in the vertical orientation state. In this case, the vertically oriented outer wall panel 30 may be lifted by using the hanging tool 10. In such a case, the hanging tool 10 is vertically attached to the upper end frame material 33a of the outer wall panel 30, and the outer wall panel 30 is lifted in the attached state.

このような場合にも、クレーンの位置によっては、吊り上げ過程において、各吊り部13A,13Bが吊り部13A,13Bの突出する側とは反対側に引っ張られることが想定される。そのため、吊り上げ過程においてフックFが吊り部13A,13B内で大きく変位すると、各吊り部13A,13Bが開く方向の力が生じて、各吊り部13A,13Bが開いてしまうおそれがある。この点、本吊り具10では、環状部19A,19Bにより吊り部13A,13B内でのフックFの変位が規制されているため、かかる場合にも、各吊り部13A,13Bが開いてしまうのを防止することができる。 Even in such a case, depending on the position of the crane, it is assumed that the suspension portions 13A and 13B are pulled to the side opposite to the protruding side of the suspension portions 13A and 13B in the lifting process. Therefore, if the hook F is largely displaced in the hanging portions 13A and 13B in the lifting process, a force in the opening direction of the hanging portions 13A and 13B is generated, and the hanging portions 13A and 13B may be opened.
