The Structus column-splice system from Eurotec offers an innovative solution for the construction of multi-storey buildings using Cross-Laminated Timber (CLT), providing seamless connections between columns across multiple floors, as well as facilitating the creation of point supported floor systems – thus improving the efficiency and stability of timber construction.
Equipped with a tube in tube system, Structus’ design combines an inner core with an outer jacket tube – ensuring the inner core achieves its maximum yielding capacity without buckling under compressive forces, while the outer tube provides critical support – increasing the overall stability of the joint. Designed to EC5 standards, Structus is engineered for strength, precision and efficiency.
Another feature of the tube in tube system is its simplicity and precision during installation. The system is self-locking, enabling timber columns to be installed on-site with speed and accuracy, helping to reduce construction time while guaranteeing high and reliable structural performance.
Structus can also support both post and slab as well as post and beam timber framing systems. Its primary function is to provide a continuous vertical load path between successive timber columns, ensuring that loads are efficiently transferred through the building structure.
To achieve this the connector uses fully threaded screws for the steel-to-wood connections. Recognising that wood fibres are weakest along the end grain, Structus uses a unique approach – screws are inserted at a 30° angle into angled, pre-drilled holes in the steel plates, which are machined using advanced CNC technology. This method significantly increases shear and tensile strength, thus safeguarding the stability and longevity of the joint.
Eurotec GmbH states: “While similar systems exist, Structus is distinguished by its sophisticated operating principles. The combination of the tube in tube core stability and the angled screw applications on the column faces, without any adapters or angular washers, represent a leap forward from traditional 90° end-grain screw methods, which are less efficient and limit overall strength.”
