この発明は法面等の地盤表面に敷設して地盤を保護する
ブロックマットの吊上げ装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a lifting device for block mats laid on a ground surface such as a slope to protect the ground.
合成繊維の織物等からなり土砂の透過を拘束するフィル

It was lifted using a lifting device. That is, as shown in FIG. 4, by using a lifting device 3 with grips 2 attached to both ends of a lifting beam l, the blocks 5 at both ends of the block mat 4 are removed from the remaining end portion 7 consisting only of the filter material 6 to which the blocks 5 are not fixed. 7 was held and lifted by the grip part 2.2.

不確実になるという欠点があった。As shown in FIG. 5, the gripping part 2 of the conventional lifting device 3 is
A pair of clamping members 8°8 are provided which clamp the remaining end 7 of the block mat 4 along the width direction. However, since conventional clamping members clamp between substantially flat surfaces, if manufacturing accuracy is poor, it is difficult to tighten with uniform force, and the remaining end 7
Since the contact area with the filter material 6 is small, there is a drawback that the grip of the block mat becomes uncertain when a shock such as an impact is applied.
この発明は上記事情に鑑みなされたものである。その目

を特徴とする。[Means and Examples for Solving the Problems] This block mat lifting device has a pair of 2. In a block mat lifting device equipped with two clamping members,
The clamping surfaces of the two clamping members are made of an elastic body, and are characterized in that they have concave and convex cross-sections that fit into each other.

形成している。FIG. 1 shows a pair of clamping members 8-1 and 8-2 of the embodiment, each consisting of a frame 9 having a U-shaped cross section and a clamping surface material 10 made of an elastic body of rubber fitted to the frame. The surface of the clamping surface material 10=1 of one diameter member 8-1 has a concave arc-shaped cross section, and the surface of the clamping surface material 10-2 of the other clamping member 8-2 has a cross section of They have an arcuate convex shape and form clamping surfaces that fit into each other.

き、余端部に損傷を与える恐れもない。This lifting device clamps the remaining end 7 of the block mat 4 between clamping face members 10-1 and 10-2 made of elastic bodies that fit together as shown in Fig. 2, so the contact area is wide. Therefore, even if there is a slight defect in accuracy, it can be held securely, and there is no risk of damaging the remaining end.
