Device for detecting performance of building curtain wall

The utility model relates to the field of detection devices, in particular to a building curtain wall performance detection device. The technical problems are as follows: a curtain wall performance detection device usually adopts a one-way pressure-bearing device to carry out compression operation, so that deformation of other positions cannot be perceived in time, the pressure-bearing performance detection performance is influenced, and the overall performance detection effect is reduced. According to the technical scheme, the device for detecting the performance of the building curtain wall comprises a building curtain wall body, an L-shaped sliding column, an L-shaped corner sleeve, a pressure-bearing assembly, a pressure-bearing clamping assembly and a guide protection assembly; according to different areas of a building curtain wall body, a controller slides along a sliding rail through a telescopic sleeve in advance, the expansion controllability is improved, an auxiliary structure is additionally insta
