| High work platform is a new type of high building construction equipment, its simpleoperation, flexible, and high efficiency, safe and reliable, convenient erection and convenient touse and repair. With the increasing high-rise buildings, high work platform in constructionindustry is more and more extensive use, its application expansion greatly improve the workingefficiency, reduce the labor intensity of homework, to adapt to the different high buildingconstruction environment, and in the building installation and maintenance industry graduallyreflect its the advantages of using. As the development of new high-rise building constructionbasic facilities, high work platform structure form and security features gradually by theindustry’s attention.This paper first studied U platform structure form, an important part of the platformstructure on the strength and rigidity of checking. On the basis of U platform ascension andquantity of the hoisting position distribution of the form is discussed. Through the because oflive load caused by the change of the platform structure stability problem analysis, calculated theplatform in every hoisting position with live load and the generated changing the maximum load,so as to determine the U platform for use of the hoist type. Using the finite element analysismethod, U platform wind load in the presence of two working state of the strength and stiffnessof the platform structure are studied. In the static analysis model based on the platform of Udynamics analysis, including modal analysis, harmonic response analysis and transient dynamicanalysis; In the meet U platform structure strength and rigidity requirements of the condition, tothe U platform structure improvement optimization, and U platform telescopic functions arestudied, telescopic structure condition, the focus of the hanging platform changes the impact of,the platform stress state and structure security effect, etc.With the increasingly global construction industry development, modern buildings inbuilding height not only have increased, and in the shape of the buildings on the structure alsoconstantly changing, so different high work platform use demand is also is increasing. U highwork platform is the main form of typical alien platform. Because of the general double hoistingway unable to effectively meet U high work platform for ascension, so in U platform designprocess, improve lifting point number selection and decorate a form hoisting position willinfluence U platform use safety and stability. At the same time in the practical engineering,design personnel often will be considered in the guarantee system structure of the strength,stiffness and stability meet the requirements, under the premise of reasonable selection andmanaging material also is very important. So the structure optimization design is always designpersonnel in the design of the work of the late serious consideration. |
