の公知手段を用いてもよいことは勿論である。Also, the wire ○ is attached to the lower support fitting 5, and in this embodiment, a vertical groove and a hole following this are provided in the upper part of the lower support fitting 5.
A wire-shaped guide 7 is formed, a wire 〇 is passed through the guide 7, and the wire C is connected to the ring shape. This is done by fitting and pressing the side surface of the wire C, but when forming the lower support fitting 5, the end of the wire 0 may be crimped and attached, or it may be attached using conventional known means. Of course, this is a good thing.

これを支持するよう構成されている。Reference numeral 10 denotes a pin, and a male threaded portion 11 is formed in the center thereof to be screwed into the female thread provided on the lower support fitting 5. When the two ends 12 and 12 touch the bottom surface of the PC board,
It is configured to support this.
本考案は上記のように構成された吊り具の2組の組合せ
によるものであり、以下その使用方法について説明する
。The present invention is based on a combination of two sets of hanging devices configured as described above, and how to use the device will be explained below.
先ず、下部支持金具5に取付けたワイヤーCを上部支持
金具1の中空部4内に挿入しておき、この下部支持金具
5をpc板Aの中空孔Bを通過させる。First, the wire C attached to the lower support metal fitting 5 is inserted into the hollow part 4 of the upper support metal fitting 1, and the lower support metal fitting 5 is passed through the hollow hole B of the PC board A.
そして、ピン10を下部支持金具5に設けた雌ネジを刻
設した透孔6に螺合させ、その両端12.12でPCC
板肉下面を支持するとともに、上部支持金具1の胴部3
を中空孔Bの上面に挿入し、その鍔部2でPCC板肉上
面を支持しておく。Then, the pin 10 is screwed into the through hole 6 provided with a female thread in the lower support metal fitting 5, and the PCC is connected at both ends 12 and 12.
In addition to supporting the lower surface of the plate, the body 3 of the upper support metal fitting 1
is inserted into the upper surface of the hollow hole B, and the upper surface of the PCC plate is supported by the collar portion 2.
このようにしてPCC板肉上下面を支持したものをPC
C板肉中空孔Bの2個に施しておき、そのワイヤーCの
露出部をクレーン等により同時に引っ張ってPCC板肉
吊り上げるのである。In this way, the upper and lower surfaces of the PCC plate are supported.
This is done in advance in two of the hollow holes B in the C plate, and the exposed portions of the wires C are simultaneously pulled by a crane or the like to lift the PCC plate.
なお、このとき利用する中空孔Bは中心に対し対称位置
となるよう設定した方が左右のバランスをとる上で好ま
しい。Note that it is preferable to set the hollow holes B used at this time so that they are symmetrical with respect to the center in order to maintain a balance between the left and right sides.
そして、この吊り上げが終了した時は、ピン10の下部
支持金具5への螺合を解き、これを取り去ってpc板A
の下面の支持を解き、下部支持金具5をPCC板肉中空
孔Bを通して引き抜くのである。When this lifting is completed, the pin 10 is unscrewed from the lower support fitting 5, removed, and the PC board A
The support on the lower surface of the PCC is released, and the lower support fitting 5 is pulled out through the hollow hole B in the PCC plate.
本考案は上記のような構成であるので、PC板の周囲と
ワイヤーとが直接接触することがなく、特にこの縁部が
取られたりして傷つくことは全くない。Since the present invention has the above-described structure, the wires do not come into direct contact with the periphery of the PC board, and there is no possibility that the edges of the PC board will be scratched or damaged.
従って、断熱材等の柔らかいものを張り合わせたもので
もその中空孔の少くとも2点以上を支持しながら確実に
吊り上げることができる。Therefore, even a material laminated with soft materials such as heat insulating material can be reliably lifted while supporting at least two or more points of the hollow hole.
また、PCC板肉中空孔Bを利用するので、従来のもの
をそのまま使用することができるばかりでなく、この中
空孔Bとワイヤー〇とは直接接触することがないので、
この中空孔Bが傷つくことはない。In addition, since the PCC board hollow hole B is used, not only can the conventional one be used as is, but also this hollow hole B and the wire 〇 do not come into direct contact with each other.
This hollow hole B will not be damaged.
更に構造が簡単で、取扱いが容易であり熟練を要しない
等の諸効果がある。Furthermore, it has various advantages such as a simple structure, easy handling, and no skill required.
