Concrete block structure for tension-compression fatigue test of ultra-high performance concrete

The utility model belongs to the technical field of building materials and structural power, and particularly relates to a concrete block structure for an ultra-high performance concrete tension and compression fatigue test. The device comprises a force transmission chuck, a pressed steel plate, an ultra-high performance concrete block and a fixing piece, the two ends, perpendicular to the end faces, of the ultra-high-performance concrete block are each provided with a steel bar embedded part, and the axial leads of the two steel bar embedded parts are collinear. The two steel bar embedded parts are sleeved with pressed steel plates and force transmission chucks from inside to outside correspondingly, and the pressed steel plates and the force transmission chucks are fixed to the steel bar embedded parts through the fixing parts. By adopting the technical scheme of the utility model, convenience is provided for accurately researching the fatigue strength and deformation performance of the ultra-high performan
