Interlocking building block for walls |
摘要 |
The building block has two identical halves with a precut recess (B). The upper face of the block can have a circular recess in each half (A) and a corresponding projection on the lower face to position the blocks against horizontal relative movement. The mortise and tenon formations can be hollow. The blocks, when interlocked, define passages for the pouring of cement to retain them together.
