Description

technical field [0001] The invention relates to the technical field of building curtain wall engineering, in particular to a detection system and a control method for the interlayer deformation performance of a building curtain wall. Background technique [0002] In the seismic fortification area, the building curtain wall should be able to meet the requirements of the local seismic fortification intensity. The interlayer deformation performance of the curtain wall is that when the main structure of the building undergoes repeated interlayer deformation and displacement, the curtain wall will keep itself and the connection with the main body without damage and function. The capacity of the obstacle, when the deformation performance of the curtain wall interlayer is tested, the curtain wall test sample should not be damaged under the cyclic action of the peak acceleration of the design test. During the interlayer deformation detection process of the curtain wall, the interlay...

AI Technical Summary

Problems solved by technology

During the interlayer deformation detection process of the curtain wall, the interlayer deformation displacement is currently measured by a pointer displacement meter. The tester observes the displacement data and manually operates the loading device, so that the interlayer deformation performance detection of the curtain wall has a long displacement cycle and low displacement accuracy. Therefore, it is difficult to meet the requirements of testing specifications
