INTERFLOOR CONNECTING ELEMENT FOR REINFORCED CONCRETE STRUCTURES Russian patent published in 2024 - IPC E04C5/16 

FIELD: valves connection devices.

SUBSTANCE: invention relates to devices for connecting reinforcement, in particular to couplings made of metal, and can be used in construction to create reinforcement frames of reinforced concrete structures. Interfloor connecting element for reinforced concrete structures includes cylindrical couplings for reinforcement rods equipped with thread, lock nut. It comprises outer and inner couplings, setting and adjusting rods. Cylindrical couplings represent a fastener in which there is a through threaded hole for detachable connection of reinforcement rods with mounting or adjusting rods. In the outer coupling there is a stepped through hole, the larger diameter of which is provided with a thread for a detachable connection with an external thread of the inner coupling. Setting rod is cylindrical, on one side of the setting rod there is a thread, and on the other side a thrust washer is mounted, and the end face of this side of the setting rod is conical. Adjusting rod is cylindrical. On one end of the adjustment rod there is a blind conical hole and is directed towards the conical end of the setting rod. Lock nut is mounted on an adjustment rod with the possibility of fixing the connection of the inner and outer couplings to each other, wherein outer and inner couplings, setting and adjusting rods are mounted on one axis between cylindrical couplings with possibility of their detachable mounting. Thread on cylindrical, outer and inner couplings, setting and adjusting rods is cylindrical, or metric, or inch, or rectangular, with right or left winding.

EFFECT: providing reliability at vertical threaded connection of reinforced concrete structures.
