PURPOSE:To stabilize the stacked layer of KENCHI blocks as well as raise the efficiency of operations by a method in which the stay bottom portion of KENCHI block is shaped into nearly cross form, each tip of the stay bottoms is positioned at each center of faces, and both angles of each tip are shaped into a notched slope form with a specific angle from the corresponding length of a specific length on the basis of the angles of the faces. CONSTITUTION:The stay bottom portion 4 of a KENCHI block is shaped into nearly a cross form, and the tips 5 and 7 of the stay bottom portion 4 are positioned at the centers of the sides 9 and 10 of the faces 2. Both angles of the tip are shaped into 45 deg. notched slopes 6 and 8 from the corresponding point of 1/2 shorter side length than the angles 11 of the faces 2. When stacking the KENCHI blocks, since two angles of the faces 2 always coincide with the angles of the blocks to be placed, the slopes 6 and 8 of the crossed ends 5 and 7 of the stay bottom portion 4 at an equal distance from the coincided angles are coupled with each other, and the stay bottom of the upper block is placed at two points on the lower block. |
