Abstract (en)
[origin: EP0039931A2] 1. Permanent formwork for a concrete floor or ceiling slab comprising at least two mutually adjoining prefabricated concrete plate elements (1, 2), wherein at least one base portion (14, 34, 35, 42, 43, 47, 51, 52) of an anchor (10, 31) is anchored in the concrete of each of the adjacent plate elements (1, 2, 32, 33) in the edge regions of said plate elements that adjoin the respective abutting edges thereof, said base portion being force-lockingly connected to a head portion (16, 36, 44, 53) which projects out of the top (15) of the plate and which, at a spacing therefrom, has a contact surface for a connecting member (11, 38) for connecting two adjacent anchors (10, 31), characterised in that said anchors (10, 31) are fitted in the edge region of two adjacent plate elements (1, 2, 32, 33) which are rigid for assembly thereof, in such a way that the contact surfaces of the head portions (16, 36, 44, 53) are disposed at a predetermined height above the underside of the respective plate elements, so that the connecting member (11, 38) secures the undersides of adjacent plate elements in an aligned condition in a vertical respect and is clamped against the contact surfaces of two adjacent anchors (10, 31) and the transverse forces which occur when clamping the connecting member and when concreting the slab (1) can be transmitted by way of the two anchors (10, 31) and the associated connecting member (11, 38).
