Steel connectors for precast concrete beams.
Traditionally, concrete beams were supported on columns using integral corbels. Apart from being difficult and costly to form in the column, they reduce headroom locally and spoil the appearance. Using BSF connectors eliminates the need for corbels, leaving a smooth soffit. Round, or odd-shaped columns present no problems. For heavy loads from beams into columns, walls or other beams, the BSF system should be used. They consist of three-part telescopic connectors, but are otherwise similar in application principle to the range of telescopic stair connectors. They are designed for heavy-duty beam supports, with capacities from 225–1100 kN. By using pairs of connectors, loads up to 1400 kN can be catered for.
