Description

Technical Field

[0001] The utility model relates to the technical field of building detection, in particular to a deformation detection device for a building curtain wall. Background Art

[0002] A building curtain wall is a protective wall surrounding a building, composed of panels and a supporting structure. It has a certain degree of displacement relative to the main structure or its own deformation capacity, and is not subject to the forces acting on the main structure. In addition to requirements for airtightness, watertightness, and wind pressure resistance, curtain walls are also required to demonstrate interlayer deformation capability. This involves using a static loading device to induce low-cycle repetitive motion in curtain wall specimens, simulating the relative deformation caused by external forces such as earthquakes and wind, in order to test the curtain wall's ability to withstand interlayer deformation.

[0003] For example, a Chinese patent discloses: a device for detecting the in-plane deformation performance of curtain walls for housing construction projects, with patent number CN211904898U. By rotating the first threaded rods on both sides of the detection box in opposite directions, one end of the first threaded rod is caused to abut the curtain wall through the top plate, thereby fixing the upper part of the curtain wall, and by rotating the second threaded rod, one end of the second threaded rod is caused to abut the lower surface of the curtain wall through the top plate. By turning on the forward and reverse rotation of the servo motor, the output end of the servo motor drives the screw rod to rotate, and then the threaded sleeve drives the abutment plate to reciprocate and push the curtain wall with the same stroke (a distance that meets the curtain wall deformation performance standard), thereby realizing rapid detection of the curtain wall deformation performance, and having the advantages of simple structure and convenient operation.

[0004] However, during the implementation of the above technical solution, it was found that there were at least the following technical problems: as mentioned above, the device is difficult to adjust according to the conditions of the curtain wall, and the device is difficult to shrink, making transportation more troublesome.
