process for the production of a dome, cones or pyramidenfoermigen cover made of concrete for building and civil engineering works.

摘要

1. A process for the manufacture of a dome-shaped, cone-shaped or pyramid-shaped concrete covering for building construction and civil engineering, particularly for container-like structures, with which consecutively annular sections issuing from the top edge of the enclosing wall of the structure are manufactured ; during manufacture of the first, annular section (A), which is attached to the encircling wall (1), radial supports (6) of a concrete form construction bearing on and consequently being supported on the encircling wall (1) on the one hand and a supporting structure (7, 8) running parallel to the encircling wall (1) and at a distance therefrom on the other hand, and during manufacture of the additional, annular sections (B, C) the radial supports (6) being supported by means of their internal ends on the supporting structure (7, 8) which is displaced towards the centre of the structure according to the width of the section (B, C), and being suspended by means of their external ends, which are directed towards the encircling wall, on the inner edge area of the hardened, annular section (A, B or C) of the covering, which edge area has been constructed without suspender beam supports or bearer supports, and during manufacture of the annular sections (A, B, C) through-going openings for passage of securing elements for the radial supports (6) are provided on these annular sections, these openings being approximately in the vertical direction and on the inner edge area of the sections, which edge area is flat on the upper and lower side.
