【発明の詳細な説明】
この発明は、組立建築物のフレームまたはパネ
ルあるいはその他各種の物体を吊上運搬する場合
に用いる保護キヤツプ付き吊り具に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hanging device with a protective cap used for lifting and transporting frames or panels of assembled buildings or various other objects.
建設工事現場等でフレームやパネル等を吊上運
搬する場合、フレームやパネル等の被運搬物に吊
上用アイボルトを螺合し、そのアイボルトに吊具
を係合してクレーン等により吊上運搬することが
多い。 When lifting and transporting frames, panels, etc. at construction sites, etc., a lifting eye bolt is screwed onto the object to be transported, such as a frame or panel, and a hoisting tool is engaged with the eye bolt, and then lifted and transported using a crane, etc. There are many things to do.
吊上運搬後は、吊上用アイボルトを被運搬物か
ら外して保管する必要があるが、この場合、外し
たアイボルトを放り投げたり落としたりするなど
乱暴に取扱うとアイボルトにおける螺杆の先端側
のねじ山が潰れることがある。 After lifting and transporting, it is necessary to remove the lifting eyebolt from the object being transported and store it. In this case, if the removed eyebolt is handled roughly, such as by being thrown or dropped, the screws on the tip side of the screw rod of the eyebolt may be damaged. Mountains may collapse.
この対策として、アイボルト不使用時すなわち
アイボルト保管時またはアイボルト運搬時に、螺
杆の先端側に保護キヤツプを抜挿自在に圧入嵌合
して螺杆のねじ山を保護し、アイボルト使用時に
保護キヤツプを取外すことが考えられる。 As a countermeasure against this, when the eyebolt is not in use, i.e. when storing the eyebolt or transporting the eyebolt, a protective cap is removably press-fitted onto the tip side of the screw rod to protect the screw thread of the screw rod, and when the eyebolt is used, the protective cap is removed. is possible.
また保護キヤツプを取外したときその紛失を防
止するために、アイボルトと保護キヤツプとを紐
等により連結しておくことが考えられるが、この
場合は、アイボルトを被運搬物の雌ねじに螺合す

プ付き紐が吊下がつているので、アイボルトの螺
合操作を行ないにくく、かつ繰返し使用している
うちに紐が切れて保護キヤツプが紛失する恐れが
あり、さらに多数のアイボルトを山積み状態で保
管したとき、各アイボルトに付属する紐が絡み合
つて分離しにくくなる等の問題が発生する。 In addition, in order to prevent the protective cap from being lost when the protective cap is removed, it is conceivable to connect the eyebolt and the protective cap with a string or the like, but in this case, the operation of screwing the eyebolt into the female thread of the object to be transported is necessary. When doing this, since the string with the protective cap hangs from the eye bolt, it is difficult to screw the eye bolt together, and there is a risk that the string will break and the protective cap will be lost during repeated use. When these eye bolts are stored in a pile, problems arise such as the strings attached to each eye bolt becoming entangled and difficult to separate.
