MOUNTING ARRANGEMENT Russian patent published in 2016 - IPC F16B37/08 

FIELD: construction.

SUBSTANCE: disclosed is a mounting arrangement. Mounting arrangement includes a quick-clamping nut, consisting of two parts (31, 32), each part of nut (31, 32) having one slot (33, 34) for placement of threaded rod (1), and locking element (10) with at least one through hole (20) for fixation of quick-clamping nut (30) on threaded rod (1). Locking element (10) has through hole (20) resting surface (22) for pressing nut parts (31, 32) to threaded rod (1), as well as centering surface (24) for alignment of threaded rod (1) in through hole (20). Locking element (10) in through hole (20) has transition surface (23) adjacent to locking surface (22) and centering surface (24) and extending between resting surface (22) and centering surface (24). On resting surface (22) on at least one section opening angle is smaller than that of transition surface (23). Invention also discloses another fastening device. Said device includes quick-clamping nut (30), consisting of two parts (31, 32), each part of nut (31, 32) having one slot (33, 34) for placement of threaded rod (1), and locking element (10) with at least one through hole (20) for fixation of quick-clamping nut (30) on threaded rod (1). Locking element (10) has in through hole (20) resting surface (22) for pressing parts of nut (31, 32) to threaded rod (1), as well as centering surface (24) for alignment of threaded rod (1) in through hole (20). Locking element (10) in through hole (20) has transition surface (23) adjacent to locking surface (22) and centering surface (24) and extending between resting surface (22) and centering surface (24). Quick-clamping nut (30) has at least one bearing surface (41), which restricts axial retraction of quick-clamping nut (30) in through hole (20). Transition surface (23) is distant from parts of nut (31, 32), when quick-clamping nut (30) adjoins bearing surface (41) to locking element (10), and resting surface (22) presses part of nut (31, 32) to threaded rod (1).

EFFECT: fastening elements.
