<P>PROBLEM TO BE SOLVED: To facilitate laying work of a block mat by using a hanger allowing the block mat to be hanged down from a heavy machine, and to provide the hanger with a simple structure. <P>SOLUTION: A hanger for a block mat allows a block mat 1 to be hanged down from a heavy machine 7. The block mat 1 includes a block 3 fixed on the top face of a sheet 2. A hanger 8 comprises: a base 12 extending in a horizontal direction and hanged down so as to be ascended/descended by a heavy machine 7; and left and right locking parts 13, 13 which are formed at both ends of the base 12 in a left-right horizontal direction A, respectively, and which allow left and right locked parts 14, 14 formed at the left and right ends of the sheet 2 of the block mat 1, respectively, to be locked/unlocked. In a state in which the left and right locking parts 13, 13 are locked to the left and right locked parts 14, 14, respectively, when the base 12 is ascended to bring the block mat 1 into a free state, the block mat 1 warps into a downward convex arc shape. <P>COPYRIGHT: (C)2012,JPO&INPIT |
