JPS6019103Y2 - Lifting and reversing jig for concrete products - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a concrete product lifting and reversing jig for lifting concrete products such as side gutters and turning them face up.

The inventor has previously provided lifting and reversing jigs for various concrete products (Utility Application No. 57-52731, Utility Application No. 57-89469, Utility Application No. 57-121954,
Jitsugan No. 57-121955).

However, the present invention is an improvement on these conventional ideas, and even if the side wall of the concrete product has an upward slope from the bottom to the top, it is also possible to The object of the present invention is to provide a lifting and reversing jig for concrete products that can be easily adjusted and reversed even if the distance to the tip of the side wall is different.

The present invention will be explained below based on embodiments shown in the drawings.

FIG. 1 is an exploded schematic diagram showing a concrete product lifting and reversing jig A according to the present invention.

In the drawings, reference numeral 1 indicates a support rod.

The support rod 1 has a substantially inverted U-shape, and its upper end is formed as a connection part 3 for a hanging member 2 such as a wire, and its lower end is formed so that a spacer 4, which will be described later, is approximately perpendicular to the support rod 1. It is formed as a support hole 5.5 through which it is inserted to be connected to.

Reference numeral 4 designates a spacing holder, and the spacing holder 4 is formed in the shape of a cylindrical pipe, and a modified washer 8 having an inclined surface 6 on one side is fixed to one end thereof.

Reference numeral 7 indicates a washer.

A plurality of washers 7 are fitted into the spacer 4.

The washers 7... are configured to have different widths.

Further, one of these washers 7... is provided with a pin hole 9 penetrating therethrough in a right angle direction.

Further, the spacer 4 is also provided with pin holes 9.

Reference numeral 10 indicates a reversal bar.

The reversing rod 10 is formed as a long round rod, and a plurality of pin holes 11 are bored at one end thereof at intervals.

In the above, the state of use of the present invention is shown in Figures 2 to 4.
This will be explained with reference to the figures.

First, the inclined surface 6 of the deformed washer 8 fixed to the spacer 4 is brought into contact with the side wall 13 formed by the locking hole 12 of the concrete product B to be inverted, and the deformed washer 8 and the side wall of the concrete product B are brought into contact with each other. 13 Space holder between sides 4
A plurality of washers 7... are fitted and adjusted so that the hanging member 2 does not come into contact with the tip 14 of the side wall 13 of the concrete product B.

Next, the reversing rod 10 is inserted into the spacer 4, and a locking hole 12 is inserted into the side wall 13 of the concrete product B.
Insert the tip of the reversing rod 10 inside.

After that, a plurality of washers 7 are inserted into the spacer holder 4 from the rear end side of the spacer 4, and the locking pin 15
are inserted into the pin holes 9 and 11 to fix the reversing rod 10 to the spacing holder 4.

Note that this operation is performed on the side wall 1 on the opposite side of concrete product B.
3 is also carried out, and after these operations are completed, it will be lifted up and turned over using a crane or the like.

By the way, when the concrete product B is turned over, the deformed washer 8 that is in contact with the side wall 13 of the concrete product B
Although the reversing rod 10 and the reversing rod 10 rotate at the same time, there is no problem because the space between the spacing holder 4 and the support holes 5, 5 is free.

Thus, the present invention has been devised from the above-described configuration, and the reversing jig A according to the present invention can be used even if the side wall of the concrete product has an upward slope from the bottom to the top. This has the excellent advantage that even if the concrete product has a different distance from the position where the rod is inserted to the tip of the side wall, it can be easily adjusted and reversed.
