Building block stack with wrapping straps

摘要

The building blocks are stacked up, possibly also side by side, to form cubes and then for wrapping have on the four identical parallel edges protective edge bars (6) which extend over the entire length of these edges. The edge bars have right-angled recesses whose surfaces fit snug against the adjoining faces (3,5) of the blocks along the edge. The blocks are held secure by tension straps (20,21,23,24) which fit in the edge bars and run round the cube crossing over each other. The edge bars can be identical one-piece bars with grooves (15,16,17) holding the tension straps. The edge bars can have a closable chamber to hold dry mortar. The tension straps can be made of glass fibre fabric also for use on site. The outside faces of the blocks can be made hydrophobic prior to stacking.
