    The ice surface of the Skating Hall in Maribor is covered with the roof structure consisting of two main externally prestressed concrete beams from which a secondary steel structure is suspended, and ... the perimeter columns supporting the roof structure; the dimensions of the covered area are 67,60 x 67,10 m. The main bearing structure of the roof consists of two externally prestressed beams,axially spaced for 12,20 m. At both ends the beams are supported by a steel cross girder set on the top of the double - sided column. The main beam consists of a concrete box beam ( 1,60 m high the width of the top flange is 2,40 m and of the bottom flange S,90 m), reinforced concrete spacing elements (at the axial distance of 9,00 m and of different length) and of 6 tendons LH 12 / 15,2 mm, set in the steel shoes atthe bottom side of the spacing elements. The tendons are pulled into galvanized steel ducts / 2,5" and they are prestressed according to the system P. H. - Gradis and anchored at the front of the conrete box beam. The anticorrosive protection of tendons has been effected by injecting the lithium grease Lipleks S-2 EP after the second - phase prestressing.
