Abstract
An interlocking block pier assembly is disclosed including a plurality of blocks for stacking in a generally vertical column to support a load thereon. Each pair of adjacent blocks is interlocked by a key formed generally radially in a first block of the pair and a complementary keyway formed generally radially in the other block of the pair for receiving the key to prevent the blocks in the pair from rotating or moving laterally relative to each other.
Claims14
An interlocking block pier assembly comprising:
- a plurality of annular blocks for stacking in a generally vertical column to support a load thereon;
- and
- means for interlocking each pair of adjacent blocks in said column including key means formed generally radially in a first block of said pair and complementary keyway means formed generally radially in the other block of said pair for receiving said key means to prevent said blocks in said pair from moving rotatably or laterally relative to each other;
- said key means including four key segments arranged radially at generally 90 degree intervals about said first block and said keyway means including four keyway segments arranged radially at generally 90 degree intervals about said other block.

- and
- a solid base element disposed at a lower end of said column for engaging the ground and means for interengaging said base element with a lowermost block in said column to prevent said lowermost block from moving rotatably or laterally relative to said base element, said means for interengaging including secondary key means formed in one of said lowermost annular block and said base element and secondary keyway mens formed on the other of said lowermost block and said base element for receiving said secondary key means;
- said secondary key means including four key segments arranged radially at generally 90 degree intervals about said lowermost block and said secondary keyway means including a cross-shaped keyway formed on said base element for receiving said key segments.
