Prefabricated segmental beam side span few-support splicing structure and construction method
The invention provides a prefabricated segmental beam side span few-support splicing structure and a construction method. The support splicing structure comprises a triangular bracket arranged on a transition pier, a bracket opposite-pulling system for fastening and fixing the triangular bracket, an under-beam cushion block arranged on the transition pier, two side span 0# beam sections arranged on the under-beam cushion block, an inter-beam cushion block arranged between the two side span 0# beam sections, a temporary opposite-pulling system for fixing the side span 0# beam sections, a plurality of side span beam sections sequentially spliced next to the side span 0# beam section, and temporary prestressing tendons arranged on the plurality of side span beam sections; and the triangular bracket is fixed on a transition pier below the side span beam sections through the bracket opposite-pulling system. The prefabricated segmental beam side span construction is realized, the use of brackets is reduced, the bridge girder erection machine is not reinforced, the dependence on the geological condition under the bridge is greatly reduced, the application range is enlarged, the adopted materials are detachable and practical, the construction efficiency is improved, and the engineering cost is reduced.
本发明提供一种预制节段梁边跨少支架拼装结构及施工方法，所述支架拼装结构包括设置在过渡墩上的三角托架、对三角托架进行紧固固定的托架对拉系统、设置在过渡墩上的梁下垫块、设置在梁下垫块上的两个边跨0#梁段、设置在两个边跨0#梁段之间的梁间垫块、对边跨0#梁段进行固定的临时对拉系统、紧挨边跨0#梁段依次拼装的多个边跨梁段、设置在多个边跨梁段上的临时预应力束，所述三角托架通过托架对拉系统固定在边跨梁段下方的过渡墩上。本发明实现了预制节段梁边跨施工，减少支架的使用，同时不加强架桥机，对桥下地质情况的依赖性也大大降低，增加了使用范围，同时所采用的材料可拆卸周转实用，提高了施工工效，降低了工程造价。
