摘要:
The present invention relates to a method for the manufacture of concrete objects by means of a slidable moulding assembly by feeding a concrete mass down from a movable container onto a support bed and vibrating the concrete for the compression of the concrete. The invention eliminates any risk of fissures in the final object primarily by inserting a reenforcement rod into the mass along with some water through an axial bore in a sleeve guide on the container, after a majority of the compressing or compacting of the mass has occurred. A container-carried rotating screw is used for separating, by means of its threads, the concrete remaining in the container from the concrete in the object being formed.

The invention relates to building structures in which slabs are laid on beams, and in which it is desired to maintain the slabs coplanar irrespective of difference in level of the beams and slabs. The invention provides rubber wedges, used in pairs so as to be adjustable to different thicknesses, located between the slabs and beams at intervals and held in place by adhesive.

A MACHINE FOR MOULDING THE END WALLS OF CONCRETE BUILDING ELEMENTS OF U-SHAPED CROSS SECTION, THE SIDE AND BOTTOM WALLS OF WHICH ARE BEING MOULDED IN CONSIDERABLE LENGTHS IN SLIDING MOULDS. THE MACHINE COMPRISES TWO INNER MOULDS BEING SPACED APART IN THE LONGITUDINAL DIRECTION OF THE MACHINE AND SERVING TO FORM ONE SIDE OF THE MOULD FOR MOULDING THE END WALL, AND A BLADE ADAPTED TO
BE RAISED AND LOWERED IN THE GAP BETWEEN THE INNER MOULDS AND TO SERVE AS AN INTERMEDIATE MOULD WHEN MOULDING THE END WALLS OF TWO SUCCESSIVELY DISPOSED BUILDING ELEMENTS.
