Steel concrete support, comprises length and cross direction steel reinforcing structures which are covered with concrete and sealed at both ends with plates

摘要

The support (1) comprises a high strength concrete material and a length direction reinforcing structure (2) made from high strength steel. The open ends of the reinforcing structure are sealed by bonding or spot-welding head and foot plates (6, 7) to it. A bow frame (3) or spirally wound reinforcing structure extends around the length direction reinforcing structure.
