Formwork bodies and methods for creating vertical openings

Abstract

Formwork body for constructing vertical penetrations in a floor slab (G) for pipes or conduits, for which it is proposed that it be formed from at least one metallic side part (S1, S2, S3, S4) forming a closed cladding surface with a height (h) corresponding to the thickness (d) of the floor slab (G), wherein in a lower area of ​​the at least one side part (S1, S2, S3, S4) a base plate (1) covering the cross-section enclosed by the at least one side part (S1, S2, S3, S4) and which can be inserted into the at least one side part (S1, S2, S3, S4) is arranged with recesses (7) for pipes or conduits, and in an upper area of ​​the at least one side part (S1, S2, S3, S4) openings or slots are provided for inserting or placing reinforcing bars (5) that cross the cross-section.
