BLOCK SET

Provided is a block set with increased bearing power to prevent an upper block from being forwardly pushed as combining and supporting adjacent blocks each other by inserting a trivet combination unit into grooves of first and second blocks and combining a trivet combination unit with fixing units of an upper block. The block set comprises a first block(1), a second block(2), and a trivet combination unit(3). The first block(1) includes first and second grooves(11,12), a third groove(13), and a penetration hole(14). The second block(2) includes first and second grooves(21,22), a third groove(23), and a penetration hole(24). The third groove(13) of the first block(1) and the first and second grooves(21,22) of the second block(2) are formed in a triangle, and combined with three combination pins of the trivet combination unit(3). The trivet combination unit(3) is combined with fixing units(4,5) of an upper block.
