Bridge support set of prefab., prestressed concrete component - uses support with most variable cross-section as basic member, with other supports

摘要

The bridge support set consists of prefab. prestressed concrete structural elements. Each element has a trapezoidal cross-section with side walls (2), which diverge in the upward direction and terminate in flanges (3) which extend sideways and outwards. Three sizes of the elements are used. The support (1) with the most varied cross section forms a base, while the other ones form recesses of the basic one. The cross-sectional parts of all supports are shaped to fit together. ADVANTAGE - Increased variability, and improved transverse load-bearing capacity.
