Device for detecting curtain wall suction cup method counter-force support rod piece strain

The utility model discloses a device for detecting the strain of a curtain wall suction cup method counter-force support rod piece, and relates to the technical field of glass curtain wall detection. The rigidity equivalent rod piece is a rod piece with a symmetrical rigidity cross section, and the rigidity of the rigidity equivalent rod piece is equivalent to that of the tested rod piece; the connecting assembly is used for detachably and fixedly connecting the rigidity equivalent rod piece with the two ends of the tested rod piece; the loading device is used for detachably and fixedly connecting the middle part of the rigidity equivalent rod piece and the middle part of the measured rod piece, adjustably loading and generating a load which enables the rigidity equivalent rod piece and the measured rod piece to be close to each other after the connection, and measuring the load; and the strain acquisition unit is used for detecting the strain value of the rigidity equivalent rod piece.
