Research on Deformation Monitoring Technology of Intelligent Building Curtain Wall Construction
Since the measured value after monitoring by the existing monitoring technology exceeds the standard range,the reaction force of the support at both ends of the truss is high,so the monitoring technology of structural deformation of intelligent building curtain wall construction is studied.Select suitable heat-insulating materials and glass to form a curtain wall,and design the curtain wall through 3Dmax,CAD and other software to ensure that the curtain wall structure has sufficient bearing capacity.BIM technology is applied to partition modeling to detect the collision problem in the design process of intelligent building curtain wall.The tension meter is used to test the cable force,the jack is used to control the cable force error,the displacement of the cable head is calculated,and the reading in the display is recorded to get the test cable force value.A phase 3D laser scanner is used to irradiate the laser by a laser pulse transmitter,and the signal reflected back by the laser is collected through the receiving device to form a point cloud model in the form of target point transformation.The deviation between the point cloud model and the design value is compared to complete the monitoring of the structural deformation.The test results show that the horizontal displacement of the deformation monitoring points of the five groups is between 0mm and 4mm.The results of the reaction force at both ends of the support of the truss are less than 3kN,and the results are in line with expectations,indicating that the deformation monitoring technology in this paper can control the degree of deformation and achieve better construction results.
