Formwork strength detection equipment

The invention relates to the technical field of stress detection, in particular to mold shell strength detection equipment, which is used for detecting a mold shell sample with two large ends and a small middle part, the two ends and the middle part of the mold shell sample are in conical surface transition, and the mold shell strength detection equipment comprises a rack, a sealing cylinder and two clamping mechanisms, a sealed first cavity is defined by each clamping mechanism and one end part of the mold shell sample; the mold shell sample is sleeved with the sealing cylinder, and a sealed second cavity is defined by the sealing cylinder, the mold shell sample and the two clamping mechanisms. High-pressure gas is introduced into the second cavity to form positive pressure, and the clamping mechanism enables the first cavity to form negative pressure. The high-pressure gas in the second cavity tends to be far away from the two ends of the mold shell sample through the conical surface on the mold shell sampl
