Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a block suspending tool used for transporting and constructing concrete blocks and the like, and more particularly to a block suspending tool laid on a slope.

[0002]

2. Description of the Related Art A block body laid on a slope, in particular, a through hole is formed so as to contact the mutual end faces thereof to cover the slope entirely and to form a communication hole in the vertical direction of the slope. Wire ropes and synthetic resin ropes were used during the transportation and construction of the blocks that were pierced.

[0003]

As a method of locking the rope, the two ropes are arranged separately on the lower surface of the block body, or the two ropes are inserted into the through holes of the block body to balance the ropes. Since it is hoisting while maintaining the rope, it takes time and effort to lock or release the rope one by one at the start of lifting the block body and at the end of installation, and it is very difficult to lift the block body with a predetermined gradient and with good balance. There was a problem. Further, since this kind of block body is laid directly on the slope surface from the lower side of the slope to the upper side, and the abutting surfaces are brought into contact with each other, the rope contacts the existing lower block body in the locking method. There is a difficulty in that the upper and lower block bodies do not come into close contact with each other at the joint end surface and the rope sandwiched between the block bodies having a large mass must be pulled out after installation. Further, when the wire rope is used, the block body is damaged and the commercial value is lowered.

[0004]

That is, the means for solving the above-mentioned problems of the present invention is that the retaining culms 1, 1 provided separately and the hanging culvert 2 provided in the upper part of the central portion thereof are respectively provided. A suspender for a block, which is continuously provided in a U-shape in a side view by a continuous member 3 at a rear end portion thereof, and is provided with a plurality of gradient adjusting holes 4 for adjusting a suspended state of the block on the suspending rod 2. To provide.

As another means, a holding metal fitting 5 which is rotatable in the vertical direction is pin-joined to the front part of the hanging culm 2, and the holding metal fitting 5 is arranged to prevent the rotation. It is to provide a hanger for a block in which a slide culm 9 that abuts on the upper surface or the lower surface of 2 is horizontally installed.

[0006]

Since the present invention has the above-mentioned structure, the retaining culms which are provided separately are inserted into the through holes penetrating the block body and the gradient adjusting holes provided in the hanging culms. When you fix the shackle and lock the rope etc. and lift it up,
There is an effect that the work of attaching and detaching the hanger can be easily and quickly performed and can be hung without damaging the block body. In addition, by selecting a desired gradient hole from a plurality of gradient adjusting holes and hoisting it, it is possible to adjust the hanging gradient of the block body from horizontal to the same slope as the finishing slope by shifting the center of gravity. .

Further, even if the locking culm is inserted from the upper side of the block body having an inclined slope and the block body is inclined downward together with the block suspending tool, the pressing metal fitting provided on the suspension ridge comes into contact with the block body. Since the sliding is prevented and the sliding is prevented, it is possible to use it safely even on a steep slope and to obtain an effect that the block suspending tool does not get in the way during installation.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 to 3, two rods are separated from each other in the left-right direction in the front view to form locking culms 1, 1 and a plate shape provided on the upper part of the center of the locking culms 1, 1 The hanging culm 2 and the locking culms 1, 1 are connected in a U-shape in a side view by the connecting member 3 at their rear end portions. The suspension culvert 2 is provided with a plurality of gradient adjusting holes 4a, 4b, 4c, 4d, respectively, from a front end to a substantially 1/3 portion to a rear end portion in a side view.

In addition, in the front part of the hanging culvert 2, two plate members 5a,
The hanging culm 2 is sandwiched by 5a, and the plate members 5a, 5
At the rear end of a, a pressing metal fitting 5 is provided, which is rotatably joined to the hanging culm 2 by a pin 6 and has a backing plate 5b fixed to the lower surface of the front end thereof.

Further, the plate member 5 constituting the above-mentioned pressing metal member 5
