HINGED JOINT OF WOOD ELEMENTS COUPLING IN TRUSS Russian patent published in 2013 - IPC E04B1/38 

FIELD: construction.

SUBSTANCE: joint comprises coupled wood elements with strengthening rods installed in them and metal support elements fixed at the ends. Ends of coupled elements are sawn at the right angle to their faces. Support elements are made of two plates of different height, which are connected to each other stepwise. The larger plate is arranged as adjacent to the end and is displaced along its height towards the lower face. Middle parts of support elements lean in the middle with eccentricity relative to axes of the upper belt of the structure against a steel hinged roll. The roll is fixed with a sheet joint plate with a rigid pad installed at the side of the net. The pad is fixed on the lower faces of wood elements with the help of strengthening rods. The rigid pad is made in the form of a support table with two sloping surfaces, to which net elements are fixed.

EFFECT: increased bearing capacity, strength and exclusion of stress risers.
