Concrete slab mould table - has end recesses in transverse walls unsymmetrical in relation to central plane

摘要

The concrete slab mould table fits in a moulding machine, being particularly for slabs having tubular apertures running in the lengthwise direction. It comprises a baseplate and adjustable walls, the lengthwise ones comprising strips hinging downwards and outwards, while the transverse ones are adjustable perforated strips with recesses in the ends for protrusions on the lengthwise ones. Additional adjustable walls each have bosses at one end fitting in the transverse wall perforations, and at the other an extension for fixing to the baseplate. The recesses (13) are unsymmetrical in relation to a first central plane (16) extending in the direction (15) of the perforated strips (3), and symmetrical in relation to a second plane (17) at right angles to the first and intersecting the strips centrally.
