Description

[Detailed description of the invention] [Purpose of the invention] Industrial field of application The present invention makes it easy to expand and contract a rod according to the size of a concrete product, and to easily reduce the length of a wire rope hanging at both ends. The present invention relates to a jig for suspending and transporting concrete products by a crane so that the concrete product can be suspended.

2. Description of the Related Art Conventionally, when installing a concrete product such as a U-shaped groove brought into a site with an opening facing downward, a hanging metal fitting attached to a lower end of a wire rope hanging at both ends of a hanging and conveying jig is used. The concrete product is inserted into the insertion hole on the side of the concrete product, the concrete product is suspended and transported by a crane, and the concrete product is turned upside down so that the opening of the concrete product faces upward.
It has been installed afterwards.

Therefore, if the size of the suspending jig or the length of the wire rope is not appropriate, the component of the wire rope in the inserting direction of the tension of the wire rope is larger than the force for maintaining the suspending metal in the inserting hole, and the hanging metal The concrete product may fall out, endanger the worker due to the concrete product falling accident, damage the concrete product, and make the concrete product difficult to turn over because the wire rope catches the concrete product at the time of turning over. Therefore, there is a drawback that a jig and a wire rope for hanging and transporting corresponding to various types of concrete products must be prepared.

Problems to be solved by the present invention The present invention does not require a jig for suspending and transporting concrete products corresponding to the size of concrete products. It is an object of the present invention to provide a hanging and conveying jig for preventing the occurrence of an accident due to a fall and damage to a concrete product, and for facilitating the inversion of the concrete product and for safely suspending and conveying the concrete product by a crane.

[Effect of the invention]

In short, in the present invention, the elastic member 4 and the elastic core material 10 are formed in a square pipe shape, and the elastic core member 10 is slidably fitted into the elastic portion 4 to provide the elastic member 2 and the elastic member. 4 and a plurality of adjusting holes are provided in the telescopic core member 10, and rope adjusters 3, 3a for inserting and fixing wire ropes 25, 25a are provided at both ends of the rod body 2, and the rope adjusters 3, 3a are provided. The lengths of the hanging portions 28, 28a of the wire ropes 25, 25a can be freely adjusted by adjusting the lengths of the hanging portions 28, 28a.
, 15, 15a are provided with abutment portions 18 having a larger diameter than the adjusting holes 8, 8a,... At the upper end thereof. .., 15, 15a... A jig which rotatably supports an oval locking member 19 whose diameter is longer than the diameter and whose shorter diameter is smaller than the adjustment hole 8, 8a. 3 and 3a are the upper surfaces 6 at both ends of the rod 2;
13 and U-shaped cuts 9 and 12
When the wire ropes 25 and 25a are inserted and fixed in the rope adjusters 3 and 3a and the U-shaped cuts 9 and 12, the rod 2 is disposed between the wire ropes 25 and 25a. Since the constituent members of the main body 1 do not protrude in the left-right direction of the wire ropes 25 and 25a, the main body 1 is not conveyed while the concrete product W such as a U-shaped groove is suspended and conveyed.
Can be installed smoothly without getting caught on the earth and sand walls of the place where the burial is to be buried.
Since a part of the rod protrudes in the left-right direction of the wire rope as in the jig of 61-22941, such a protruding portion is caught on the earth and sand wall of the place where the concrete product is buried at the time of suspension conveyance, and is caught. As a result of the shock, the rod body is inclined and the distance between the wire ropes cannot be maintained, and as a result, the U-shaped groove hanging jig at the tip of the wire rope can be pulled out and the U-shaped groove can be completely eliminated. Concrete product W
The rod 2 is a tensioned wire rope when suspended
A pressing force is applied in the contracting direction of the rod body 2 by 25 and 25a, and the rod body 2 is in a sandwiched state, so that a stable horizontal state can always be maintained, and the wire rope is held by the rod body 2 in this state.
The interval between the hanging portions 28, 28a at 25, 25a can be maintained.

In addition, since the elastic member 4 and the elastic core 10 are formed in a square pipe shape, the elastic core 10 does not rotate with respect to the elastic member 4, and when adjusting the length of the rod 2, the elastic core 10 is simply attached to the elastic core 10. Adjustment holes 8 and 8a provided respectively by simply inserting and inserting the elastic core material 4
, 15, 15a ... can be matched, for example, the length of the stretchable core material relative to the stretchable member, such as a rod made of a round rod-like stretchable core material that can be advanced and retracted from a round pipe-like stretchable member. As a means for fixing for adjustment, a fixing bolt is protruded inward of the elastic member, a flat surface is formed on one side of the elastic core material so as to contact the fixing bolt, and the elastic member is It is not necessary to stop the rotation to fix it, and it is not necessary to form a flat surface on one side of the elastic core material for stopping the rotation, so that an extra step for manufacturing the same can be eliminated.

Adjustment holes 8, 8a,.
At the upper end of the insertion rod 16 which can be detachably inserted into 5, 15a ..., an abutment portion 18 having a larger diameter than the adjusting holes 8, 8a ... is provided. 15, 15a... The adjusting holes 8, 8a..., 15, 15a. Adjustment holes 8, 8a that match with the forward and backward operation of
.., 15, 15a, etc., the insertion member 16 is inserted in a state where the engagement member 19 of the insertion member 16 is vertically supported by rotation from above, and the engagement member 19 of the insertion member 16 projecting from below is By horizontally supporting the rotation, the insertion rod 1 from the adjustment holes 8, 8a.
6, the elastic core member 10 is fixed to the elastic member 4, and the rod 2 can be adjusted to a desired length.
Also, it is possible to omit troublesome work such as inserting a bolt into each of the adjusting holes 8, 8a..., 15, 15a. The one-touch operation of the member 19 can simplify the operation of expanding and contracting the rod 2 and increase the efficiency of the adjustment operation.

Therefore, according to the present invention, by making the rod 2 extendable and contractable, the rod 2 can be expanded and contracted without preparing a hanging and conveying jig corresponding to the size of the concrete product W. Suitable for concrete products W.

Also, the rod 2 can be easily expanded and contracted so that the concrete product W does not get caught on the wire ropes 25 and 25a, and the length of the wire ropes 25 and 25a can be easily adjusted. When the concrete product W is suspended, transported, inverted, and installed, it prevents accidents due to the falling of the concrete product W and damage to the concrete product W,
Its practical effect is extremely large, for example, it is safe and the concrete product W can be easily inverted.
