LOAD-BEARING STAIRCASE ASSEMBLY AND STAIRCASE Russian patent published in 2007 - IPC E06C7/50 E04F11/35 

FIELD: construction, particularly staircases including a number of composite modular members.

SUBSTANCE: load-bearing staircase assembly comprises angle member and linear elongated unit fastened to one angle member face by means of hinge connection with two degrees of freedom in angle member face plane. Free end of linear elongated unit is provided with orifice for releasable hinge connection member receiving. The linear elongated units are fastened to both faces of angle member from inner or outer sides thereof by means of hinge connections with two degrees of freedom in each angle member face plane. Each linear elongated unit has at least one orifice to receive fastening member adapted to connect staircase going or riser. Staircase including at least two above load-bearing assemblies is also disclosed.

EFFECT: provision of load-bearing assembly of three-dimensional structure, which expands functional capabilities of three-dimensional structure surface forming, namely for easy and convenient staircase shape and parameters variation in dependence of current task without additional means and with the use of limited number of simple modular members, as well as extended range of load-bearing staircase unit application.
