Conventionally, lifting clamps for lifting concrete products such as concrete U-shaped grooves have a base rod 52 erected on the clamp body (the clamp body is not shown in the conventional products in Figures 3 to 7). A grip ring 53 is connected to the upper part of the clamp body, and a lifting arm body 57 shown in FIG. A lifting ring 51 for lifting the crane is connected to the upper part of the base rod 52, and a wire, for example, is inserted through the lifting ring 51, and the wire is locked to the hook of the crane to lift the clamp body. Two types have been proposed, one for crane lifting work and one for crane lifting work, which is equipped with the hanging upper arm body 57 shown in the figure. This is impossible because the wire can move from side to side within the hole in the gripping ring 53. Therefore, in the type for crane lifting work shown in Fig. 4, the shape of the hole in the lifting ring 51 is such that the wire does not move from side to side. ).
しかし、これらの二タイプを常備しておくこと
は不経済であるということで、最近、第５，６，
７，図に図示したようなクランプ本体にハンド作
業とクレーン吊り作業との両方に兼用し得るよう

案されている。 However, it is uneconomical to keep these two types on hand, so recently, the 5th, 6th,
7. A clamp as shown in the figure has been proposed in which a lifting arm body 57 designed to be used for both hand work and crane lifting work is attached to the clamp body.
しかし、これら第５，６，７図に図示した従来
品には次の欠点があることが確認されている。 However, it has been confirmed that the conventional products shown in FIGS. 5, 6, and 7 have the following drawbacks.
まず、第５，６図の従来品の場合であるが、第
５，６図の従来品は、ハンド作業の為に握持環５
３を手で握持して引き上げると握持環５３に突設
されたクレーン吊り作業用の吊上孔５５を設ける
為の突部５８が手に当たり手が痛くて非常に引き
上げにくい欠点がある。 First, in the case of the conventional products shown in Figs. 5 and 6, the conventional products shown in Figs.
3 by hand and pulling it up, the protrusion 58 protruding from the grip ring 53 for providing a lifting hole 55 for crane lifting work hits the hand and hurts the hand, making it very difficult to pull it up.
また、第７図のＴ形タイプの場合、手で引き上

間に位置させて水平握持環５６を下側からすくう

にくいという欠点がある。特に、水平握持環５６
と基杆５２との交叉部は吊上げ孔５５を形成する
為径大に形成されているから尚のこと人指し指と
中指の付け根が痛くなるのである。 In addition, in the case of the T-shaped type shown in Fig. 7, to pull it up by hand, the base rod 52 must be positioned between the index and middle fingers and the horizontal grip ring 56 must be gripped from below in order to generate force. However, like this, base 5
2 is positioned between the index finger and the middle finger and the horizontal grip ring 56 is grasped so as to be scooped up from below, the disadvantage is that the bases of the index finger and middle finger become painful and it is very difficult to pull up. In particular, the horizontal grip ring 56
Since the intersection between the base rod 52 and the base rod 52 is formed to have a large diameter to form the lifting hole 55, the bases of the index and middle fingers become painful.
本考案はこれらの従来品の欠点を解決したもの

The technical object of the present invention is to provide a clamp that solves the drawbacks of these conventional products and can be used for both hand work and crane lifting work.

A base rod 2 is installed approximately at the center of gravity of the clamp body 1 for lifting concrete products such as concrete U-shaped grooves.
is erected, and the grip ring 3 is connected to the upper part of the base rod 2, and the suspension hole 4 for hanging the crane is provided in the base rod 2 or the grip ring 3, and when not in use, a hole 4 is provided for gripping the grip ring 3. For hand work and crane hoisting work, the hoisting hole 4 is provided in a manner that it can be raised and lowered freely so as not to get in the way, and the shape of the hoisting hole 4 is set to such a shape that the wire or hook does not move laterally when engaged with the wire or hook. This relates to a clamp that can be used for both purposes.
吊孔４は本機をハンド作業用として使用する場

吊り作業が行える。
The hanging hole 4 is provided so that it does not get in the way when the machine is used for hand work, so hand work can be done by folding down the hanging hole 4, grasping the grip ring 3, and hoisting the machine. , raise the hanging hole 4 and open the hanging hole 4.
For example, a wire can be inserted through the wire, and a crane hook or the like can be hooked to the wire to lift it up, thereby carrying out crane lifting work.
また、吊孔４はワイヤーまたはフツクを係合さ
せた場合、ワイヤーまたはフツクが左右動しない
形状に設定されている為、クレーン吊りに際して
ワイヤー等が左右動して吊上物が斜めになつたり
して吊り上げに支障を来すことはない。 In addition, the hanging hole 4 is set in such a shape that the wire or hook does not move left or right when the wire or hook is engaged, so the wire or the like will move left and right when the crane is hoisted, causing the object to be lifted at an angle. There is no problem with lifting.
図面の吊上腕体１４は、基杆２と握持環３との
交叉部にＵ字状の吊環５を軸着して吊環５を起伏
自在に設け、握持環３の上縁と吊環５の頂部内周
縁とで吊孔４を形成した場合である。
The hanging humerus body 14 in the drawing has a U-shaped hanging ring 5 pivoted at the intersection of the base rod 2 and the gripping ring 3, and the hanging ring 5 is provided to be able to rise and fall freely, and the upper edge of the gripping ring 3 and the hanging ring 5 This is a case where a hanging hole 4 is formed with the inner peripheral edge of the top.
吊孔４の形成は、頂部内周縁が湾曲縁に形成さ
れている為、例えば吊孔４に係合したワイヤーが
左右動してもクランプが斜めになつたりすること
はなく、吊上物は常に適正状態で吊下げされるこ
とになる。 The hanging hole 4 is formed so that the inner peripheral edge of the top part is a curved edge, so that even if the wire engaged with the hanging hole 4 moves left and right, the clamp will not become slanted, and the suspended object will not be tilted. It will always be hung in proper condition.
