Abstract
Basket as cantilever construction of major equipment, there are many types, some countries such as Japan and France have finalized a series of products. 80 years from the last century, China began using this technique has also made great achievements. Highways, bridges, tunnels and other infrastructure continue to scale in large, long-span direction. At present large-scale, long-span bridge construction widely used in environmental adaptability of the cantilever casting method. Hanging Cantilever construction equipment is carried out when necessary construction machinery, including a large diamond-shaped hanging basket device widely used in bridge construction. Hanging Basket Design China have all been adapted cantilever construction of high-strength, lightweight, long-span development, from a PC or a steel cantilever beam was initially parallel to the truss construction Hanging type, then gradually developed into a diversified structure increasingly The more light, more and more reasonable force, the construction more convenient, more and more widely applied.
This design uses Lozenge hanging basket, introduced the triangular cradle design principles, triangular cradle design, construction methods and the main calculation steps, described cantilever construction technique. The process of mapping and calculating the main use of MIDAS / Civil and OutCAD engineering software
Hanging is the cantilever construction of key equipment, Cradle main function is to support the template, to bear the weight of fresh concrete. Hanging usually by the following components: load-bearing system, suspension system, template system, anchoring devices, running the system and working platform
Hangs basket's cast, the outline templet, the bottom die and the principal truss computation is hangs the basket design the key component, this article carries on the explanation. From hangs basket's stress computation to start to analyze, through the intensity checking calculation, the amount of deflection examines calculated that designs appropriately hangs the basket section size, hangs the request which satisfiedly the basket design must achieve. In this design also has many deficiencies, looks can propose the valued suggestion, thanks specially.
