Protection of the large-span bearing glued wooden constructions

In article are considered the questions of safety of large-span bearing glued wooden constructions (GWC) during storage on a building site and when carrying out installation works. Presented the results of long observations for change of moisture conditions glued massive elements when exhibiting in the open air. It is shown that for stabilize the moisture condition of the GWC in exploitation process, it is necessary to use paint coatings with low vapor- and water permeability. Substantiated the measures of complex protection of large-span GWC from wetting, biologic damage and fire. Proposed measures to protect constructions from cracking and delamination during the building and exploitation. Noted the importance of using swelling-up flame retardants for the protection of constructions against fire, that reduce structural fire safety GWC, and compatible with bio- and waterproof. Paid attention to the necessity for adherence of technology of GWC’s protective processing at manufacturing plants.
