The utility model discloses a concrete test piece curing frame. The concrete test piece maintenance frame comprises a maintenance frame body, the maintenance frame body comprises four supporting columns and at least two supporting cushion layers used for containing concrete test pieces, each supporting cushion layer comprises a frame and at least two cylindrical supporting rods, the supporting rods are installed in the frame in parallel, and each supporting rod is sleeved with a plurality of rotatable round pin rollers. According to the utility model, the concrete test piece is placed on the round roller, and when the concrete test piece is subjected to air shrinkage deformation, the round roller slightly rotates to adapt to the shrinkage of the concrete test piece, so that the friction force and the constraint effect between the concrete test piece and the support cushion layer are reduced; meanwhile, the concrete test piece is in linear contact with the cylinder, so that the contactarea is small, normal moi
