DTS and BSF Telescopic Beam Connectors
Precast concrete beams can be connected to columns or to other beams using the DTS and BSF range of connectors. They provide an alternative to casting corbels which are difficult and costly to form, as well as reducing headroom and compromising aesthetics.
Conceptually, the DTS range is similar in design and usage to TSS stair connectors, although the usage orientation is different: DTS connectors are used ‘vertically’ in application. Originally designed for connecting precast Double Tee floor elements, the DTS system can also be used for lightweight beam connections.
For high-load beam connections (up to 1100 kN), the ideal solution is the BSF system, which is a 3-part connection incorporating a solid high-strength steel ‘knife’ to transfer loads between beams and columns, or beams to beams.
