Lepené lamelové dřevo - trvanlivost lepených spojů.

Abstract

Glued laminated timber is construction material on wood basis. It is compounded by system of plates joined together by glued joint of cut timber. It is possible to use it for different types of constructions in civil engineering and bridge constructions and therefore have to meet requirements, which are proved by laboratory tests. One of these requirements is durability of glued joints. Durability of glued joints can be affected already during manufacturing process of construction elements. Manufacturing process must meet all requirements of standards. I viewed the influence of the environment on durability of bonded joints in research part of my thesis, this influence was simulated by accelerated ageing. I evaluated the durability on the basis of shear strength test of joints according to standards ČSN EN 392 and ČSN EN 386.
