Steel fiber reinforced concrete and construction method of reinforced prefabricated floor slab thereof

The invention discloses steel fiber reinforced concrete and a construction method of a reinforced prefabricated floor slab thereof so as to solve the problems that an existing prefabricated slab assembly structure is poor in integrality and anti-seismic property. The construction method includes the steps that part of a surface layer of the splicing portion of the prefabricated slab is rejected, anchor bars are planted, reinforcing meshes are laid on the surface, and then steel fiber reinforced concrete is poured on the surface. By means of the mechanical property advantages of the steel fiber reinforced concrete and the good adhesive propertybetween the prefabricated floor slabs after reinforcing, integrity, crack resistance, ductility and durability of the prefabricated slab structure can be improved substantially, and the anti-seismic property of the prefabricated floor slab floor (roof) is improved remarkably. 本发明公开了种钢纤维混凝土及其加固预制楼板的施工方法，以解决现有预制板装配结构整体性及抗震性能差的问题。本方法首先将预制板拼接部位剔除部分面层，植入锚筋，表面铺设钢筋网片，然后在表面浇筑钢纤维
