KLBQUADRO flat elements

Easy-to-handle large blocks / approval Z-17.1-852

The KLBQUADRO flat elements are large blocks, which are currently not yet regulated in DIN standards. Standard elements (with butt joint interlocks on both sides) in thicknesses of 11.5 cm, 15.0 cm, 17.5 cm, 20.0 cm  and 24.0 cm are supplied separately, as are mixed pallets with supplementary formats of length 373 mm and 247 mm as bricks with toothing on both sides or as end bricks with a smooth butt surface on one side, and blocks of length 497 mm as end blocks.

KLBQUADRO flat elements are no longer cut to length or divided at predetermined breaking points, but supplemented by supplementary elements of the same height with lengths of 373 mm and 247 mm. Thanks to these intermediate lengths half-height masonry in 25 cm or 12.5 cm steps is achievable. Non-modular dimensions, offset layer, height and length balance are mostly created using masonry supplementations via existing, statically and acoustically coordinated precision blocks and precision stones, so expensive cuts are generally not required. In addition to the required mini-crane, which can move two blocks at once, the individual KLBQUADRO flat element can also be moved manually by two masons thanks to its manageable size and weight. The wall integrations are handled using butt joint technology per perforated connecting strip in every position. The masonry connection must be mortared interlocking.

The manufacture and use of the KLBQUADRO flat elements is regulated by approval Z-17.1-852.
