Abstract
A wall is constructed from precast concrete blocks stacked in tiers in which adjacent blocks are secured together to increase the strength of the wall. Anchors are embedded in the tops of at least some of the blocks. The ends of the blocks have vertical grooves which form a vertical opening when the ends of two blocks abut. The blocks in the tiers are offset so that the openings between blocks in one tier are positioned above the anchors on the blocks on the adjacent lower tier. The blocks in each tier are secured together by a tensioned cable extending through aligned passages in the blocks. Locking members are placed in the openings to secure the ends of the abutting blocks to an anchor in an adjacent lower block.
Claims15
A wall including an anchor, two blocks each having an end abutting the end of the other of said blocks, said two blocks defining a vertical opening between said abutting ends positioned above said anchor, means extending into said vertical opening securing said two blocks together, and means in said vertical opening securing said two blocks to said anchor.
A method for securing two wall blocks, comprising the steps of:
- a) forming an anchor in a surface;
- b) forming first and second wall blocks, each wall block having an end defining a vertical groove;
- c) positioning said first and second blocks together end-to-end above said surface with said grooves abutting to form a vertical opening between said blocks and with said vertical opening positioned above said anchor;
- and
- d) inserting a member in said opening to secure said first and second blocks to said anchor.
