本考案はＵ字溝等のコンクリート製品を吊上げ
て表向きにするためのコンクリート製品の吊上げ
反転工具に関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a concrete product lifting and reversing tool for lifting and turning a concrete product such as a U-shaped groove upward.
従来より考案者はコンクリート製品を表向きに
するための種々の吊上げ反転工具を創案してい
る。
In the past, inventors have devised various lifting and reversing tools for turning concrete products face up.
そして、従来の吊上げ反転工具はその一対の吊
上げ部材がチエーンで形成されていたり、ワイヤ
ーロープで形成されているものである。 In the conventional lifting and reversing tool, the pair of lifting members are formed of a chain or a wire rope.
しかし、この様に吊上げ反転工具の吊上げ部材

になる。 However, when the lifting member of the lifting and reversing tool is formed of a chain or wire rope like this, when the insertion rod is inserted into the insertion hole of the concrete product to be lifted and the product is lifted, as shown in Figure 5. The wire rope or chain will be subjected to stress in the direction of arrow P, and the insertion jig will also be tilted diagonally as shown by the broken line.
そして、ひいては差込棒が曲がり、コンクリー
ト製品の差込孔から抜けやすくなりきわめて危険
であるとの問題点があつた。 Furthermore, there was a problem in that the insertion rod would bend and easily fall out of the insertion hole of the concrete product, which is extremely dangerous.
また、従来では吊上げ部材の長さは変更でき
ず、吊上げるべきコンクリート製品の長さに合わ
せて反転工具も交換しなければならないとの不合
理があつた。 Furthermore, in the past, the length of the lifting member could not be changed, and it was unreasonable that the reversing tool had to be changed to match the length of the concrete product to be lifted.

Thus, the present invention was devised to deal with the problems and unreasonableness of the conventional method, and the connecting portions of the chain-shaped member units constituting the lifting member are formed as intersecting portions that intersect with each other and intersect with each other. However, when a concrete product is lifted, the interlocking intersection portions interlock, and the lifting member is formed into a straight bar shape, and even if stress is applied to the side of arrow P, it will not bend inward, and therefore there will be no difference. The object of the present invention is to also provide a lifting and reversing tool for concrete products that does not bend the loading bar.

溝２０が設けられており、該凹溝２０同士が直角
に食い合つて連結されているものである。 That is, as shown in the figure, an overhang 21 is formed at the upper end and the lower end of the chain 10, respectively, and overhangs toward the inner periphery, and a rectangular groove 20 is provided approximately at the center of the overhang 21. , the grooves 20 are connected to each other by interlocking with each other at right angles.
しかして前記の様な連結状態であると、前記部
材ユニツト１１を上方に引張つた場合、前記食い
合い交差部１３が食い合つて、直線的な棒状のも
のとなり、左右前後のいずれの方向の応力にもた
わまないものとなる。 However, in the above-mentioned connected state, when the member unit 11 is pulled upward, the interlocking intersection portions 13 interlock and form a linear rod-like object, which causes stress in any direction, left, right, front, or back. It becomes something that does not sag.
ところで、部材ユニツト１１，１１の端部には
各々雌ねじ部１４，１４が設けられた連結体１
５，１５が形成されている。 By the way, the connecting body 1 is provided with female screw portions 14, 14 at the ends of the member units 11, 11, respectively.
5 and 15 are formed.
そしてこの連結体１５，１５間には端部に雄ね
じ部１６，１６を有した調整棒１２が連結される
様になつている。 An adjustment rod 12 having male threaded portions 16, 16 at its ends is connected between the connecting bodies 15, 15.
この調整棒１２は交換可能であり、各種の長さ
のものを用意しておくものとする。 The adjustment rod 12 is replaceable, and various lengths are prepared.
しかして少なくとも２本以上の部材ユニツト１
１…とその部材ユニツト１１，１１間に連結され

ることになる。 Therefore, at least two or more member units 1
1... and the adjustment rod 12 connected between the member units 11, 11, the lifting member 9 is constituted.
次に符号１７は差込治具を示す。該差込治具１
７は前記吊上げ部材９の下端部に連結され、水平
に貫通する貫通孔を有する治具本体１３と、この
治具本体１８の貫通孔を挿通する差込棒１９を備
えている。 Next, reference numeral 17 indicates an insertion jig. The insertion jig 1
Reference numeral 7 is connected to the lower end of the lifting member 9 and includes a jig main body 13 having a horizontally penetrating through hole, and an insertion rod 19 inserted through the through hole of the jig main body 18.
以上において本考案の使用状態について説明す
ると、先ず吊上げるべきコンクリート製品Ａの大
きさ、長さに合わせて吊上げ部材９の長さを決定
する。この長さの調整は調整棒１２を使用して行
なうものとする。 To explain how the present invention is used above, first, the length of the lifting member 9 is determined according to the size and length of the concrete product A to be lifted. This length adjustment is performed using the adjustment rod 12.
しかして、吊上げ部材９の長さが決定したら、
コンクリート製品Ａの差込孔Ｂ，Ｂに各々差込棒
１９，１９を差込む。 Once the length of the lifting member 9 is determined,
Insert the insertion rods 19, 19 into the insertion holes B, B of the concrete product A, respectively.
この際吊上げ部材９を構成する部材ユニツト１
１…はこの部材ユニツト１１を構成する複数のチ
エーン１０…の食い合い交差部１３…が食い合つ
ていないため簡単に曲げることが出来、前記差込
孔Ｂ，Ｂに差込棒１９，１９を簡単に差込むこと
ができる。 At this time, the member unit 1 constituting the lifting member 9
1... can be easily bent because the interlocking intersections 13... of the plurality of chains 10... constituting this member unit 11 are not interlocking, and the insertion rods 19, 19 can be easily bent into the insertion holes B, B. can be easily inserted.
尚、一対の吊上げ部材９，９間の間隔は横架材
６を貫挿する連結部材４，４を移動させることに
よつて調整をしておくものとする。 Incidentally, the distance between the pair of lifting members 9, 9 shall be adjusted by moving the connecting members 4, 4 which penetrate the horizontal member 6.
そしてこの状態でコンクリート製品Ａを吊上げ

すると、部材ユニツト１１を構成する複数のチ
エーン１０…の食い合い交差部１３…が食い合
い、前後左右の動きが規制され、吊上げ部材９は
直線的な棒状になる。 Then, the interlocking intersections 13 of the plurality of chains 10 constituting the member unit 11 interlock, restricting movement in the front, rear, left and right directions, and the lifting member 9 becomes a straight rod.
そして、コンクリート製品Ａを吊上げることに
より吊上げ部材９にＰ方向の応力が加わるが、こ
の応力を複数のチエーン１０…が受けることにな
り、Ｐ方向にたわむことがない。 When the concrete product A is lifted, stress in the P direction is applied to the lifting member 9, but this stress is applied to the plurality of chains 10, so that the lifting member 9 does not bend in the P direction.
また差込治具１７が斜めに傾むくことがないか
ら差込棒１９が曲がるおそれもない。 Furthermore, since the insertion jig 17 is not tilted diagonally, there is no risk of the insertion rod 19 being bent.
以上の様にして吊上げた後、コンクリート製品
を反転させ、その後地上に降ろして作業は終了す
る。 After lifting as described above, the concrete product is turned over and then lowered to the ground to complete the work.
本考案は以上の構成よりなり、本考案によるコ
ンクリート製品の吊上げ反転工具であれば、複数
のチエーンの食い合い交差部が食い合つて吊上げ
部材が直線的棒となり、たとえ矢印Ｐ方向に応力

The present invention has the above-mentioned configuration, and in the concrete product lifting and reversing tool according to the present invention, the interlocking intersections of the plurality of chains interlock and the lifting member becomes a straight bar, even if it is subjected to stress in the direction of the arrow P. It does not bend inward even when
よつて差込棒も曲がることがなく安全性の高い
吊上げ反転作業を行なうことができる。 As a result, the insertion rod does not bend, and highly safe lifting and reversing work can be performed.
また、コンクリート製品の大きさ、長さに合わ
せて調整棒を交換すれば一種類の反転工具で多種
類のコンクリート製品を吊上げ反転することがで
き、コスト的にも安価にしうる等のすぐれた効果
を奏する。 In addition, by replacing the adjustment rod according to the size and length of the concrete product, you can lift and flip many types of concrete products with one type of reversing tool, which has excellent effects such as lower costs. play.
