Kloiber, Michal ; Tippner, J. ; Hrivnák, J. ; Vichrová, Gábina ; Valach, Jaroslav
The technical solution of this diagnostic device for in-situ and laboratory measuring of conventional strength and the module of deformation by opening clamps in a drilled hole belongs to the field of quality and material property testing, especially concerning timber. In dependence on the specific technical solution, the device can be used for an establishment of conventional strength and the module of deformation of any material by opening clamps in a drilled hole in the examined volume. It also finds application in the situations when resistance drilling cannot be used and the mechanical properties of timber need to be established through the entire section of the examined element. Its main advantages are its speed and simple operation without a need for power distribution network.
Diagnostic methods for evaluation of construction timber
Heřmánková, V. ; Kloiber, Michal ; Tippner, J. ; Anton, O.
In the present time, there is an effort in the Czech Republic to increase the share of realization of wooden structures. For this reason the necessity to pay higher attention to wood as building material, to learn how to inspect its quality before starting the building as well as of the already bulit-in wood is evident. The paper performs diagnostic methods for evaluation of construction timber being used at the workplaces of the authors. The methods are sorted according to the kind of invasiveness onto non-destructive, semi-destructive and destructive.
