RETAINER OF REINFORCEMENT RODS (4 EMBODIMENTS) Russian patent published in 2020 - IPC E04C5/16 

FIELD: construction.

SUBSTANCE: invention relates to construction, namely to devices for connection of reinforcement rods during assembly and installation of reinforcement bars for reinforced concrete structures. Fixator for reinforcement rods consists of two support plate elements 1 and 2 of the same profile and a locking device made of material having elastic properties. In the support plate elements 1 and 2 in the longitudinal section there are cavities 3 the walls of which are made with bent equal side flanges 4. Locking device includes rod 6 of rectangular profile with periodic hooks 7, which tips are directed to base of pin 6, located in corner of one of side shelves 4 of plate element 1 and hole 9 of rectangular profile, under pin 6 with hooks 7 formed on diagonal side flange 4 of plate element 2. Inlet hole 10 of rectangular profile on the side of input of pin 6 with hooks 7 is slightly larger than its cross section. Output hole 11 is slightly smaller than inlet hole 10 to prevent spontaneous release of pin 6 with hooks 7 from it.

EFFECT: technical result of the invention is simplification of the process of fixation of reinforcement bars, increased reliability of the connection unit and wider range of technical means aimed at fixing reinforcement rods of different profile, diameter and material, as well as for formation of frames of different configurations.
