JOINING DEVICE Russian patent published in 2008 - IPC F16B5/02 

FIELD: devices for joining parts at simultaneous compensation of gap between said parts.

SUBSTANCE: device for joining mutually spaced parts includes first part having threaded portion, first supporting surface for engaging with construction part and member for preventing rotation of first part relative to construction part; second part having second supporting surface for engaging with other construction part, threaded surface and duct for placing fastening member. Threaded surface of second part engages with threaded portion of first part. Duct of second part has surface portion whose diameter is less than inner diameter of duct; said surface portion is formed with possibility of engaging with fastening member in such a way that rotation of said fastening member causes respective rotation of second part while determining axial position of second part relative to first part. At screwing-in fastening member, second part moves from first part for engaging with other construction part in the same direction as that of screwing-in fastening member. In the result joining device automatically compensates gap between mounting surfaces during installation works.

EFFECT: improved design, possibility for automatically compensating gap between two mutually spaced parts.
