COUPLING FOR CONNECTING CONSTRUCTION ELEMENTS Russian patent published in 2023 - IPC F16B7/06 

FIELD: construction.

SUBSTANCE: means for connecting construction elements used to connect concrete building blocks and structures. The coupling contains outer and inner half-couplings axially interconnected by a threaded connection to form a cavity bounded by the inner surface of the outer half-coupling and the end face of the inner half-coupling. An upper stud is installed in the axial hole of the outer half-coupling, with an external thickening located in the said cavity and limiting the axial movement of the upper stud relative to the outer half-coupling. A lower stud is installed in the through axial hole of the inner half-coupling by means of a threaded connection.

EFFECT: reduced requirement for the accuracy of the relative position of the construction elements being connected.
