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.
A construction element for limiting the fore part of a formwork, wherein said element is prefabricated of concrete, with a width corresponding to the thickness of a construction work to be fabricated and a modular length, comprising openings arranged in rows to allow the pushing through of reinforcing irons, pipework, or tubes and being provided with a reinforcement mesh which extends over said openings and prevents an outflow of concrete when concrete is poured into a formwork containing said element, wherein outside longitudinally extending edges of said element are provided with a finished surface generally matching a finish of a construction work to be erected, said element including longitudinally extending stepped portions on opposite sides of each of said outside longitudinally extending edges, and said element including a protruding shoulder at one end and a recessed shoulder at an opposite end, said shoulders being mutually complementary with respect to one another such that a plurality of said construction elements can be abutted end-to-end in precise alignment.
A construction element for limiting the fore part of a framework, wherein said element is prefabricated of concrete, with a width corresponding to the thickness of a construction work to be fabricated and a modular length, comprising openings arranged in rows to allow reinforcing irons, pipework, or tubes to be pushed therethrough and being provided with a reinforcement mesh which extends over said openings and prevents an outflow of concrete when concrete is poured into a formwork containing said element, wherein outside longitudinal edges of said element are each provided with a finished surface generally matching a finish of a construction work to be erected, and wherein said element includes longitudinally extending stepped portions on opposite sides of said finished surfaces, said stepped portions providing means for receiving an abutment for holding the element in place between side members of a formwork.
A prefabricated construction element for use in a formwork for pouring concrete, comprising:
