Zvýšení životnosti dřevěných konstrukcí vystavených povětrnosti

Abstract

This thesis is devoted to the actual topic of the use of wood in construction. Attention was focused on the construction of footbridges for pedestrians and cyclists and to increase their life span. The aim of this study is to evaluate the strengths and weaknesses of wood and propose possible measures that would increase the utility value and service life of wooden structures. In this work it deals with also glued lamellar wood, the history of its creation and use, as well as an evaluation of its strengths. Finally there is the conduct and results of experimental measurements of the new insulating materials Polyurea. The aim of this experiment is to record the behavior of the insulating material and the timber in their joint action. The last part deals with the verification of static behavior of the real structure footbridge in Velký Šenov.
