Can timber take centre stage in modern construction alongside concrete and steel? Explore how hybrid construction techniques are revolutionising building practices with Rothoblaas' breakthrough connectors. Discover more about these innovations and their applications by reading the full article.

Hybrid construction—the integration of various materials and techniques—has significantly expanded timber's role, allowing it to be used as a primary material even in large-scale structures traditionally dominated by concrete and steel. The benefits of this hybrid approach include enhanced construction speed and sustainability.
 
To make these hybrid solutions more accessible, standardised and certified connectors are essential. These connectors must accommodate the different tolerances of construction systems like timber and concrete. The new Rothoblaas catalogue addresses these needs across various levels of hybrid construction.

Raised Installation

Every timber building starts with a concrete foundation, protecting the timber from water and moisture. Elevating the timber on a concrete kerb enhances this protection. However, this method can slow installation due to the differing tolerances of timber (measured in millimetres) and concrete (measured in centimetres). Rothoblaas offers solutions such as the TITAN DIVE , which fastens timber directly into concrete casting, and the UP LIFT, which allows timber installation before the kerb is cast.

Prefabrication

Indoor prefabrication under controlled conditions offers significant advantages in quality and efficiency. On-site, these prefabricated elements can be quickly positioned and fastened. This method also facilitates disassembly, making it easier to recycle materials or modify structures during renovations or extensions. To support prefabrication and disassembly, Rothoblaas introduces the RADIAL and RING connectors, designed for structural panels and both beams and panels, respectively.

Post-and-Beam Structures

The glulam Post-and-Beam technique enables the construction of large-scale structures with extensive spans, a feat previously achievable only with concrete. The new ALUMEGA connectors, certified for very high strengths, complement Rothoblaas’ range of connectors for these structures.

Post-and-Slab Structures

Gaining popularity as an alternative to the Post-and-Beam system, the Post-and-Slab method now includes solutions capable of handling unprecedented loads for timber. The TC FUSION system exemplifies hybrid construction by rigidly connecting two glulam panels through concrete casting, enhancing the system initiated with SPIDER and PILLAR post connectors.

Timber Frame Structures

Light-frame structures are increasingly significant in modern construction. The new Rothoblaas catalogue expands on these structures with new fastening systems and products designed to optimize performance. The WOODY connector, Rothoblaas’ first timber connector with a dovetail shape, facilitates prefabrication with tolerances unachievable by metal plate systems. The WKR DOUBLE angle bracket, suitable for both Timber Frame walls and CLT, is another notable addition.

To dive deeper into these innovative solutions and explore the full range of products and applications, read the complete article on Rothoblaas blog.
