聚苯泡沫芯模在中小跨径连续梁板桥中的应用

Application of polystyrene foam core mould in medium and small span continuous slab bridge

中小跨径连续梁板桥结构因其建筑高度较小,施工作业空间小,箱型内模或空心内模施工困难。本文结合淮安市北门桥工程设计实践,介绍通过聚苯乙烯一次性泡沫芯模在中小跨径现浇连续梁板桥中的应用,从而达到降低施工难度,减轻结构自重,节约工程投资和优化结构设计的目的。

The construction of the medium and small span continuous slab girder bridge is difficult because of its small building height and small construction space. With the combination of North Bridge engineering design practice in Huaian, the application of polystyrene foam core mould in medium and small span continuous slab bridge is introduced. So as to reduce the diffieulty of construction, reduce the weight of structure, save the project investment and optimize the structure of the design objective.
