| 摘要 |
The invention is a device for moulds, preferably for the moulding of so-called double T slabs, i.e. continuous concrete slabs moulded with underlying stiffening girders to form a single unit. The invention comprises mould sections that limit the space and form the underlying stiffening girders as well as the slab itself.The invention comprises an essentially fixed centre mould section (9), laterally displaceable side mould sections (12) on both sides of and a distance from the centre mould section (9) as well as vertically parallel and horizontally transversely displaceable bottom sections (22) forming the bottom in the space (21) that exists between the centre mould section (9) and the side form sections (12). Both side mould sections can be individually displaced laterally towards or away from the centre mould section (9) by means of dual-action jacking devices (20) while each bottom section (22) can be displaced vertically in the space (21) between the centre and side mould sections by means of a jacking device (29).<IMAGE> |
