Research On Hydraulic Climbing Formwork Structure Analysis And Engineering

With the rapid development of China’s high-rise buildings, as a construction process, the "climbing formwork" is a high-rise building vertical structure construction of a new template system. Hydraulic climbing formwork is an advanced construction methods use hydraulic equipment to make the template automatically upwards along the wall, without the use of lifting equipment, hydraulic climbing system of the clamping device is the building template construction equipment in the more advanced construction technology apparatus. Released by the Ministry of Construction, the construction industry10hydraulic climbing formwork technology promotion as a technical content, thus emphasizing the importance of applied research on hydraulic climbing formwork.The paper first introduces the working principle of hydraulic climbing formwork, climb mode device system components, to climb the key technologies in the process, the template configuration, the layout of the machine, the principle of division of the construction section and the non-standard layer to climb also discussed the climbing formwork device modular and light design ideas.Hydraulic climbing mode system structural analysis of the production safety requirements. Through strength, stiffness and stability checking to climbing formwork system structure still and climb state. Climbing formwork structure weight in the analysis, the heap as set construction, temporary construction loads, wind loads and other load cases on the basis of checking the anchor bolt shear and uplift the performance of local carrying capacity of the concrete. By calculation, to climb the structure of the template frame rods and node analysis, recommendations for structural improvements and a comparative study.Finally, Baosheng XLPE cable tower project to explore the climbing formwork, summed up the climb of the installation of the template, load test crawl, climb and removal of construction technology and technical measures. Climbing formwork system construction costs were analyzed, to provide technical support to climb the application of the template.
