Module
X-fix connector

Connecting cross-laminated timber efficiently

The X-fix C connection system consists of point connectors with a conical, dovetail- or X-shaped geometry for joining cross-laminated timber elements.

The use of cross-laminated timber has revolutionised timber construction and offers a wide range of possibilities, particularly in multi-storey timber buildings. To date, only a limited number of connection systems have been developed specifically for the structural characteristics of cross-laminated timber. The X-fix connection system closes this gap and enables more efficient use of the material.

Module T11

The X-fix connector enables efficient connections between cross-laminated timber elements in accordance with ETA-18/0254 dated 7 May 2018.
 

CONNECTOR

The X-fix C is a point connector made of plywood with a dovetail-shaped geometry for joining cross-laminated timber elements.

Simple fabrication

Fast installation

The connector pockets can be machined at the manufacturer's factory or produced by the carpenter in the workshop or directly on site. LignaTool provides suitable templates for manual fabrication by the carpenter.


Wide range of applications

Visible connectors

The X-fix connector can also be used in exposed areas. This distinctive feature allows the load-bearing structure to remain visible and become part of the architectural design.

 

Please feel free to contact us to discuss further applications of the connector. We are happy to support you during the planning and design process.

Lateral stability

racing in multi-storey timber buildings

The X-fix connector can be used in roofs, floors and walls. Due to its high load-bearing capacity, it can transfer large shear forces and is therefore particularly suitable for multi-storey timber construction.

 

The illustration shows five X-fix C 90 connectors in each case. The connectors shown in the wall diaphragm therefore provide a characteristic shear resistance of: 5 x 28 = 140 kN. This makes it possible to provide the lateral stability of large multi-storey buildings using only a small number of highly loaded shear walls. This approach offers a high degree of flexibility in floor-plan design while reducing the number of connectors required for building bracing.


Optimisation of CLT panel layouts

Waste reduction

The X-fix connector can help reduce waste when cutting cross-laminated timber wall panels. As timber prices increase, optimisation of CLT panel geometry is becoming increasingly important.

 

Reducing material waste in cross-laminated timber enables more economical mass-timber construction.


Machine or manual fabrication

CNC or manual machining

The connector pockets can be CNC-milled directly on the CLT manufacturer's machining line. The exact position of each connector is therefore defined by the milling operation and can be used for accurate assembly on site.

 

Alternatively, LignaTool offers a routing template that allows the connector pockets to be produced manually using a router.
