Abstract

The invention relates to a permanent core for producing internal cavities in articles of vibro-compressed concrete. According to the invention, the core consists of a three-dimensional spatial region having two connected levels (5a and 5b) built on top of one another, wherein a first level (5a) of the spatial region, open at its bottom, consists of a base space (1) comprising a bottom (1a) and a cover plate (1b) arranged parallel with the bottom (1a), while the second level (5b) consists of an upright stack (2) disposed on at least one through-cut formed in a cover plate (1b) of the base space (1), where the stack (2) ends at an end plate (3) disposed parallel with the bottom (1a) of the base space (1) at a height of 70...90% of the total height dimension of the concrete article (10), with the bottom (1a) of the base space (1) having at least one respective positioning projection (4) arranged in the plane thereof in at least two directions which are normal to one another, each such positioning projection (4) having an interconnecting section (4a) and an insertion tongue (4b) disposed at the end of the interconnecting section (4a) and a load-bearing insert (9) which can also be temporarily received in the base space (1).
