The Influence of the Human Factor on the Measurement Results Acquired by Using the Resistance Drilling Device RinnTech Resistograph R650-EA
Dziadková, Aneta ; Heřmánková, Věra ; Anton, Ondřej ; Szórád, Martin
The diagnostics of wooden structures using the detection drill RINNTECH Resistograph R650-EA is one of the popular semi-destructive methods. This article deals with the issue of the influence of the human factor on the measurement results. The recommended testing direction is the radial direction, perpendicular to the grain. However, the desired direction is sometimes difficult to maintain. The experiment takes into account three different factors that may occur during the testing. The goal is to determine to what extent the human factor affects the measured results. Thanks to the conducted research, it was found that gradual tilting of the device during measurements influences the measurements most significantly.
Influence of Wood Density on Measured Values when Working with a Kučera's Drill
Černý, Pavel
Diagnostics of wooden structures is still a widely used field in construction. The measured values during testing in wood diagnostics are always influenced by the properties of the wood. One of the most important roles in wood diagnostics is moisture, which affects a wide range of physical and mechanical properties. This was not the case when testing with the Kučera`s drill, which is standardly used for masonry diagnostics. For research purposes, the drill had to be transformed for use on wooden structures. The transformation was performed on the basis of a special reduction.
