Description

TECHNICAL FIELD

[0001] The present application relates to a device for detecting the interlayer deformation performance of a building curtain wall. BACKGROUND

[0002] A building curtain wall is a building envelope composed of a panel and a support structure system, which has a certain displacement capacity relative to the main structure or a certain deformation capacity, and does not bear the action of the main structure. In addition to the requirements for air tightness, water tightness and wind pressure resistance, the building curtain wall also requires interlayer deformation performance, that is, when the main structure of the building undergoes repeated interlayer displacement, the curtain wall maintains its own and the connecting part with the main structure without damage and dysfunction. The detection of the interlayer deformation performance of the building curtain wall is realized through a quasi-static test, that is, a static loading device is used to produce low-frequency repeated motion of the curtain wall specimen, to simulate the X-axis, Y-axis, Z-axis or combined displacement deformation under the action of earthquake, wind load and the like, so as to detect the bearing capacity of the curtain wall to the interlayer deformation.

[0003] The national standard "Classification and detection method for interlayer deformation performance of building curtain wall" GB / T18250-2015 increases the requirements for out-of-plane (Y-axis dimension), vertical direction (Z-axis dimension) deformation performance and combined displacement performance of building curtain wall on the basis of the original in-plane deformation (X-axis dimension) detection of curtain wall. At the same time, the interlayer deformation performance of building curtain wall in the American standard "Static test method for evaluating curtain walls and store front systems under conditions of story drift caused by earthquake and wind" AAMA 501.4-2009 is also required to detect the deformation adaptability in X, Y and Z axes.

[0004] The existing detection technology device mainly uses a single quasi-static test device to detect the in-plane (X-axis dimension) deformation of the building curtain wall or uses a manual hand pressure jack to detect the interlayer three-dimensional deformation performance of the curtain wall. This method cannot accurately stop when the deformation reaches the limit value. In addition, the fixed support of the curtain wall specimen is generally suspended laterally on a movable cross beam. When the interlayer deformation is detected, the movable cross beam and the static pressure box body need to be released from the constraint. At this time, there is a large lateral overturning moment under the action of the self-weight of the curtain wall, which affects the accuracy of the test.

[0005] Therefore, a device for detecting the interlayer three-dimensional deformation performance of a building curtain wall is designed. The device also needs to be efficient, accurate, safe and reliable, which is a problem to be solved in the field of building curtain wall detection. SUMMARY
