Würth Wood-Concrete Composite

Wood-concrete composite refers to a construction method in which two separate cross-sections of wood and concrete are joined together to form a composite cross-section with the help of special fasteners. This is why this type of construction is also called hybrid construction.

The combination of the two building materials makes optimal use of their properties. Under bending stress, the tensile forces are absorbed by the wood, while the concrete is arranged in the compression zone. The fasteners used between the two cross-sections create a connection on the one hand, and on the other hand, the shear forces between wood and concrete are transferred as a result. In addition, the composite achieves a significantly higher load-bearing capacity of the structure.

Advantages of prefabrication

• Short construction times
• Transport and assembly costs can be drastically reduced
• Lightweight individual elements
• Favourable geometries
• No moisture ingress into the structure
• No contamination of the wooden components during the concreting process
• No separation layer required to protect the wood
• With the appropriate quality, the underside of the concrete slabs can remain
• visibleCuring and drying times on the construction site are eliminated
No need to
• support the ceiling up to the standard strength of the concrete

Advantages Wood screws

• Easy to apply
• No special requirements for personnel
• Approved systems (ETA-13/0029)
• Use of standard screws
• Variable screw length
• Small centre and edge distances due to the drill tip

Precast element

With wood-concrete composite ceilings, in which the concrete slabs have been prefabricated, visually appealing and wide-span timber beam ceilings can be realised in visual quality with a short installation time.
