Abstract
A prestressed steel support structure and method of erecting the same having bearing supports and containing at least one tension element having at least one hollow profile member extending in a catenary configuration between support locations and within which there is arranged at least one prestressing cable. The hollow profile member is provided with a filler and the prestressing cable forms a connection with the hollow profile member by means of such filler.
Claims4
An arched load-bearing structure comprising arched elements (16) and suspension elements (15) oppositely curved in a catenary shape and arranged adjacent one another,
- horizontal carriers (17) supporting said elements (16 and 15),
- at least one hollow profile member (22) extending in each suspension element (15),
- at least one prestressing cable (11) extending internally through each hollow profile member (22), said cable being secured to the hollow profile member by a filler to form a tension element (21),
- said tension element (21) extending in a catenary shape in the suspension elements (15) and over the horizontal carriers (17) into the arched elements (16), and
- said cables (11) being anchored in the arched elements (16).
A method of erecting an arched load-bearing structure, which comprises:
- drawing prestressed cables into hollow profile members to form tension elements;
- connecting the hollow profile members by means of U-shaped profile elements;
- lifting the construction;
- anchoring the prestressing cables;
- laying fabricated elements which bear on the tension elements;
- connecting reinforcement rods to one another at the bearing areas of the fabricated elements, and
- pressing out the hollow profile elements with injection cement thus securing the cables to the hollow profile members.
