であるためクレーン車が大型となる等問題点があった。As the gripping device for lifting the block mat, the one described in Japanese Patent Publication No. 61-35332 has been generally used. This device was attached to both ends of the hoisting beam, and had a structure in which the pressing member was opened and closed by moving the lever up and down, and the surplus end of the block mat was tightly held and hoisted. Since the lever is opened and closed by input in this device, the structure is heavy and labor-intensive, and there is a problem in that the entire device is complicated and heavy and the crane truck becomes large.

While holding the two parallel gripping rods, the matte ends of the mat are folded back and doubled to be inserted into the small gaps, respectively, and the mating ends are folded back and the locking rods are inserted into loops. This is characterized in that the mat excess end is gripped between the grip bars.

In FIGS. 1 and 2, gripping portions 2 are attached to both ends of a hoisting beam 1 which is hoisted by a boom (not shown) of a mobile crane. The gripping portion 2 is composed of gripping rods 3 and 3 made of two steel pipes arranged in parallel with a small gap and a frame member 4, and is attached to the beam 1 via a slide plate 5. The slide plate 5 is fixed to a desired position of the beam 1 by bolting, and the grip portion 3 is mounted by attaching a bracket 6 protruding from the upper surface of the frame member 4 to the slide plate 5 with a pin 7 as a shaft. There is. A shackle 8 is projectingly provided on the upper surface of the beam 1, and a suspension wire 9 for suspending with a boom of a mobile crane is connected to the shackle 8.

なく、把持棒3,3間で把持される。The block mat 10 is formed by laying and fixing a substantially rectangular parallelepiped concrete block 12 on the surface of a filter cloth 11 made of synthetic fiber woven or non-woven fabric, and an extra end 13 to which the block 12 is not fixed is provided at both ends. There is. In order to hoist this block mat 10 with the hoisting beam 1, the extra end portion 13 is folded back and doubled to be inserted between the gripping bars 3 of the gripping portion, and the extra end portion 13 is folded back to form a loop. Insert the locking bar 14 of square wood into the place. When the beam 1 is lifted in this state, a frictional force is generated between the double portion of the extra end portion into which the locking rod 14 is inserted and the two gripping rods 3 and the load of lifting is applied. Also, the surplus end does not slip out and is gripped between the gripping bars 3, 3.

間から引出し把持を解除し、地盤表面に敷設する。In this state, the mat is grasped, lifted and carried down to a predetermined position, the locking rod 14 is pulled out, and the mat excess end 13 is grasped by the grasping rods 3, 3
Release the grip from the space and lay it on the ground surface.

い好適である。In this embodiment, a steel pipe is used for the grip bar and a square bar is used for the locking bar, but the present invention is not limited to this. But the gripping bar,
It is preferable that the locking rod has a high friction coefficient with the extra end portion and is hard to slip. A square bar is suitable for use as a locking bar, since the extra end thereof is less likely to slip.

化、低コスト化を達成することができる。The method of gripping the block mat is to fold the extra ends of both ends of the mat into double folds and insert them into the small gaps, respectively. The extra mat part can be gripped between the two parts, and the gripping can be released by pulling out the locking rod, which eliminates the need for heavy labor and is excellent in workability. Further, the device is simple and does not require a complicated device, and thus the device can be reduced in weight and cost.
