Inner top plate formwork of bridge box girder

The utility model discloses an inner top plate formwork of a bridge box girder, and relates to the technical field of box girder inner formworks. The inner top plate formwork of the bridge box girder comprises a bottom assembly, an upper assembly and an inner supporting assembly. On one hand, in the mold withdrawing process, contact between the inner top plate mold frame of the bridge box girder and the interior of the box girder is reduced, so that friction is reduced, the box girder and the inner top plate mold frame are rapidly separated, and the production and manufacturing efficiency of the box girder is improved. And on the other hand, the inner top plate formwork of the bridge box girder can be repeatedly used, operation and overhaul are easy, the situations of rusting, blocking and the like are avoided, and the service life is prolonged. 本实用新型公开了一种桥梁箱梁的内顶板模架，涉及箱梁内模架技术领域；该桥梁箱梁的内顶板模架包括底部组件、上部组件以及内支撑组件。一方面，在撤模过程中，该桥梁箱梁的内顶板模架减少与箱梁内部产生的碰触，从而减少摩擦，以使箱梁与内顶板模架快速分离，提高箱梁生产制造效率。另外一方面，该桥梁箱梁的内顶板模架可反复使用，操作与检修简单，不会产生
