ABSTRACT:
A construction element for limiting a fore part of a formwork consists of a prefabricated element having a width which corresponds to the thickness of the construction work to be erected and a modular length. The element comprises openings for being able to push through reinforcing irons, pipework or the like tubes. Because the element is foreseen to remain in the wall, it is produced preferably with a relatively fine concrete in which a reinforcing mesh of synthetic material is enclosed, which extends also over the openings and prevents the outflow of concrete at the time of pouring the latter into the formwork. Such a shuttering element allows a fast and precise limiting of the formwork in the case the construction work is not poured in one part or is needing recesses for a crane. It requires no cleaning off or pulling off wooden parts when the joining part is produced.
