Wooden structures are largely used both in new construction and restorations.
Wood is a material with a long tradiction in constructions, and historic centres are full of example that testify it’s usage in every age, but it has a modern side to it because of its performance/weight ratio that makes building faster and makes industrializable the construction business.
Particularly in restoration works has in time become more appealing the usage of synthetic fiber (carbon) also known as fibre-reinforced plastic (FRP) for wooden truss support.
The structural adjustment interventions that call for the usage of carbon fibers have two main purposes:
Their usage shows major advantages compared to restoration techniques that call for the usage of foil and/or iron bars:
The cement that usually make up the matrix of the frp is crucial for the efficacy of the support intervention.
The epoxide resins are especially suitable for the glueing and soaking of carbon fibers because:
2° INTERVENTION EXAMPLE
Location: private space designated as a dining hall
Load increase on wooden ceiling with carbon fiber foils and epoxide resins.
Mounting systemwith longitudinal cut following, where there is, the truss bending.
Preparation of the location withhardening and firming, application resins and insertion of the foil.
Removal of resins exceeds, recleaning and color adjustments.
This system allows a reinforcement and a load increase on the truss without jeopardizing its natural appearance and historical accuracy.
