Abstract (en)
[origin: EP0275938A1] The invention starts from a formwork construction element for producing disposable formwork, into which concrete or cement is poured, especially a formwork construction element for producing the shell of shell concreting, there being between surfaces (8, 9), intended for bearing on one another, of the formwork construction elements consisting preferably of foamed plastic a plug connection which consists of, for example, peg-like projections (6) and recesses (7) receiving these, which have the same dimensions and the same grid division (R) in the longitudinal and transverse directions. To provide more alternatives for assembly by means of the formwork construction elements, including the possibility (without an appreciable loss of material) of dividing in two the formwork construction elements or of cutting off part regions, at the same time achieving a high stability of the plug connection, each of the two surfaces, that is to say both an upper surface (8) and a lower surface (9), of a formwork construction element (1), which, during operation, make a plug connection with a corresponding countersurface of another formwork construction element (1), are equipped with mutually identical projections (6) and recesses (7) fitting into one another. <IMAGE>
