Research On Safety Management Of Attached Lifting Scaffold Based On Visualization Technology

In recent years,the attached lifting scaffold,which an external protective scaffold tool,has become the first choice in high-rise building construction,but its safety problems can not be ignored.Therefore,this study will combine the safety management of attached lifting scaffold with BIM technology and Internet of Thinzgs technology to build a threedimensional visual construction management platform,which is based on WebGL technology and aims to improve the safety management level of attached lifting scaffold by changing the safety management mode.The main research contents are as follows:First,the safety evaluation system of attached lifting scaffold in service stage was established,including four criterion layers and 18 indicator layers,including scaffold performance,personnel behavior,scaffold service state and safety management.The fivescale AHP method and entropy method are used to combine the weights.The results show that the weight value of the frame using state is the highest,which should be paid more attention to in the safety management.At the same time,due to the lack of personnel unsafe behavior and management will usually increase the probability of accidents and the degree of consequences,so cross work,illegal work,early technical disclosure and safety education and training are also the top priority in safety management;Therefore,the key to the safety management of the climbing frame is to improve the management system and realize the real-time collection and transmission of the frame state data.Then,according to the weight analysis results,the safety management framework of the attached lifting scaffold is constructed by integrating the visualization and information characteristics of BIM technology and the real-time monitoring advantages of the Internet of things technology.With the help of BIMFACE lightweight technology,WebGL technology and other information means,the attached lifting scaffold visualization platform based on B/S architecture is developed,which realizes the lightweight display of BIM model in the browser,and the visual viewing of the operation monitoring data of each machine position in the 3D model.Finally,combined with a construction project,the application effect of the platform in the safety management of scaffolding construction process is verified.The results show that the visual platform of attached lifting scaffold integrating BIM technology and Internet of things technology can improve the management efficiency of attached lifting scaffold to a certain extent,and promote the application of information technology in the construction site.
