The study of the frame node connection on the cylindrical pins of the transom and the column made of laminated veneer lumber or LVL (Laminated Veneer Lumber) with preliminary strengthening of the connection across the fibers with fully threaded screws was carried out.
Rothoblaas' type VGZ propellers, which were provided for the current study.
Installed screws increased the bearing capacity of this type of assembly.
They allow you to place the pins at smaller distances than required by regulatory documents and avoid fragile destruction, which is not allowed in the design of structures.
