Research report from the evaluation of the wooden construction of the movable roof of the garden pavilion Paraplicko in Cesky Krumlov Castle

The umbrella-shaped roof of the lookout pavilion can be lifted about a meter above the parapet wall by means of a unique lever mechanism. The impulse to write out the report was an order from the Český Krumlov Castle Administration with the seat of the Castle No. 59, Český Krumlov - Latrán which required to assess the condition of all important timber elements using NDT instruments and, in particular, to measure mechanical properties of wood. For that purpose the two apparatuses designed at ITAM were used to measure continually the mechanical resistance during the pressing of the jaws in the drilled hole and the resistance during the pushing of the steel pin to the surface. Gained results should contribute to design a gentle restoration of the unique lifting devic
