桥梁箱梁模板的施工工艺与施工方法

砼箱梁有结构整体性好,强度高,外形美观,桥下可利用空间大等优点,目前在大型立交桥中的应用日益广泛。但由于其施工时箱梁结构完全现浇,跨河施工又有导流问题,因此对支撑体系的要求较高,需要精心设计排架和模板,以保证整个箱梁的施工质量。针对箱梁的内、外模设计和施工进行了一些有益的探索。

The Construction Technology and Construction Methods in the Bridge Box Template

Concrete box girder structure has the advantages of integrity,high strength,good appearance,and there is a large space under the bridge. The present application in a large overpass is increasingly widespread.However,the box structure is totally casted and construction across the bridge is also difficult,so the demand of the support system is higher,and requires well-designed bent and templates to ensure the construction quality of the box. The thesis researches on the inside and outside of the box,the mold ...
