On-line testing equipment for fireproof performance of concrete

The utility model relates to on-line testing equipment for fireproof performance of concrete, belonging to the technical field of engineering material performance testing and fire prevention and disaster resistance. The equipment is barrel-shaped, and comprises an insulating layer, a shell, a thermal-protective layer, a heating layer and a loading base plate, wherein the insulating layer is wrapped outside the shell, and the thermal-protective layer and the heating layer are fixed inside the shell in sequence. A concrete sample to be tested is arranged in the barrel-shaped equipment, and the loading base plate is arranged at the upper end and the lower end of concrete to be tested. The on-line testing equipment for the fireproof performance of the concrete can cause the concrete sample to be heated to different temperatures under the action of loading different loads on the concrete sample, can cause constant temperature to last for different periods of time, and can realize on-line real-time observation on t
