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.

By contrast, DTS and BSF telescopic connectors leave a smooth soffit and provide a simpler, more cost effective solution and are also suitable for round columns or skewed angle connections.

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.

As specialists in precast concrete car park construction, we use telescopic connectors for many key applications. Particularly, the BSF system helps us to construct a ‘modern’ frame without cumbersome corbel supports and enables rapid assembly on site. The technical back-up provided by Invisible Connections provides us with added reassurance.

I’ve used your services on my last three projects (telescopic connectors for precast and continuity strip for in-situ). You’re very good at accommodating site demands for lead-in times and value competitiveness. Very happy with the service I’ve received on all three projects and hope this relationship will continue on future developments.

Telescopic connectors provide us numerous advantages for precast stair installation. Apart from improved time and efficiency, the health and safety gains over traditional support methods are a key driver to satisfy our own needs, as well as those of our clients.
