Abstract
A concrete temperature stress testing machine system including: a concrete temperature stress testing machine and a walk-in environment simulation laboratory system; and the walk-in environment simulation laboratory system includes a walk-in environment simulation laboratory, a host control cabinet, a compressor set room, an environment room control cabinet and a computer. The concrete temperature stress testing machine achieves the temperature deformation self-compensation by using the combination of different proportions of invar and No. 45 steel, an embedded type directly measuring deformation technology of the concrete temperature stress testing is achieved by the fit between the upper and side embedded parts, the embedded rod and the extending rod. The concrete temperature stress testing machine system according to embodiments of the present disclosure may compensate the impact of the temperature deformation by itself and directly measure the true deformation of concrete, thereby having high accuracy, good long-term stability, easy operation and other advantages.
