Document Type and Number:
Japanese Patent JPS5094718
Kind Code:
A
Abstract:
Interlocking blocks are assembled in longitudinally staggered rows. The blocks are planar on their bottom side and include webs with interlocking protrusions on their upper side. The protrusions coact with the webs on adjacent rows of blocks to locate and hold the blocks in position. Corner blocks and end blocks are also provided so that a series of walls may be constructed without the need for the usual mortared joints. The protrusions are chamfered and have associated therewith an excessmaterial-receiving groove to compensate for manufacturing tolerances. A completed wall may be grouted through interconnecting cavities in the hollow blocks to provide additional strength.
