Formwork-free UHPC-NC sandwich floor slab structure and construction method thereof
The invention belongs to the technical field of concrete floor slabs, and particularly relates to a formwork-free UHPC-NC sandwich floor slab structure and a construction method thereof. The NC pouring layer and the UHPC pouring layer are sequentially arranged on the UHPC prefabricated slab, the lower reinforcing mesh is arranged in the UHPC prefabricated slab, the upper reinforcing mesh is arranged in the UHPC pouring layer, and the truss ribs are arranged on the two reinforcing meshes, so that the UHPC-NC sandwich floor slab structure can obtain a good balance between the structural strength and the construction efficiency. In addition, the invention further provides a construction method, the construction method sequentially comprises the steps that the UHPC prefabricated slab is hoisted, the NC pouring layer is formed, the upper reinforcing mesh is bound, the UHPC pouring layer is formed, finally construction is completed, the UHPC-NC sandwich floor slab structure is manufactured, and no formwork is used in the process.
本发明属于混凝土楼板技术领域，尤其涉及一种免模板的UHPC‑NC夹心楼板结构及其施工方法。本发明通过在UHPC预制板上依次设置NC浇筑层和UHPC浇筑层，且UHPC预制板内设有下部钢筋网、UHPC浇筑层内设有上部钢筋网，两个钢筋网上再设置桁架筋的方式，使得UHPC‑NC夹心楼板结构可以在结构强度和施工效率之间，获得一个不错的平衡。此外，本发明还提供一种施工方法，其步骤依次包括UHPC预制板吊运、NC浇筑层成型、上部钢筋网绑扎，以及UHPC浇筑层成型，最终施工完毕，制得该UHPC‑NC夹心楼板结构，期间没有使用任何模板。
