DTS Beam Connectors Specification

Traditionally, precast beams are traditionally supported off brackets and corbels which are difficult and costly to form, reduce headroom and compromise architectural clean lines.

The DTS range of telescopic connectors offer a cost-effective and structurally efficient alternative for end loads up to 150kN, making DTS connectors ideal for smaller beams or heavy slabs. These connectors leave a smooth soffit and are also suitable for round columns or skewed angle connections.

Application

DTS connectors are used for a diverse range of applications, including:

Connecting beams to beams and beams to columns
Linking wall units to columns
Fixing beams at unusual angles
Joining beams to round columns

Advantages

Owing to simplicity of installation, DTS connectors offer benefits over rolled steel angle (RSA) or corbel connection methods, such as:

Improved cost effectiveness
Better on site health and safety
Enhanced appearance

We have completed installation of our stairs in both cores, using TSS connectors. Everything went smoothly, quickly and easily. The new anti-uplift brackets have done the job perfectly.

Matthew Bialecki, Senior Engineer, J. Coffey Construction Ltd

Thank you for sending the calculations and installation advice. The new calculation software looks great. Very clear, user friendly and with more design checks than the previous version. It’s a pleasure to see how you are constantly improving.

Stefan Pauceanu, Senior Structural Engineer, Ground Construction Ltd

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.

Peter Crofts, Precast Design Manager, SCC Design Build Ltd

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.
