REINFORCEMENT TEST BENCH Russian patent published in 2016 - IPC G01N3/08 

FIELD: construction.

SUBSTANCE: invention relates to testing of construction articles. Test bench comprises support tube with central through hole for reinforcement coaxial vertical arrangement in it and with bottom to reinforcement lower end support. Reinforcement upper end is secured in concrete prism or corner element, which are installed from above on support pipe. Reinforcement lower end is secured in cross-beam made in form of two U-bars. Cross beam is installed horizontally in symmetrical side cutouts in supporting pipe lower part. Vertical force on reinforcement is performed by loading device via load metal pipe, which is installed coaxially to supporting pipe. Loading metal pipe rests on reinforcement upper end with plugged upper end. Loading pipe lower end rests on cross bar ends extending beyond supporting pipe. Loading metal pipe walls thickness is not less than 5 mm. Pile driver is used as loading device for dynamic action on reinforcement. With static action on reinforcement hydraulic press is used.

EFFECT: obtaining accurate parameters of reinforcement anchoring strength in concrete, as well as determination of physical and mechanical parameters of reinforcement under extension with both static and dynamic effects.
