Title:
CHAINED BLOCK
Document Type and Number:
Japanese Patent JP2003286723
Kind Code:
A
Abstract:
To provide chained blocks which can be easily and surely mutually chained, kept in a chained state for a long time and shorten a construction period.
A polygonal flat plate has projection parts and recess parts with a same outer peripheral shape formed on a peripheral part, and sides of the circumference are formed partially acutely or obtusely inclinedly. When a great number of the flat plates are planarly arranged in substantial contact with each other in toward a same direction, the projection parts and the recess parts of the adjacent flat plates are engaged with each other so as not to be separated by pulling in a planar direction, and the inclined sides are mutually overlapped.
