Prefabricated hollow slab core-buried pore-forming pipe
The invention provides a prefabricated hollow slab core-buried pore-forming pipe, which comprises a pipe body, wherein the pipe body is a penetrated hollow pipe of a honeycomb structure. Therefore when the pipe body is the penetrated hollow pipe of the honeycomb structure, and the hollow pipe is applied into a prefabricated hollow slab, the end parts are penetrated; if a support core pulling mold is also arranged in the hollow pipe, the support core pulling mold is pulled out after the concrete casting is completed, so that the pipe wall thickness of the pore-forming pipe can be greatly reduced; the deformation of the pore-forming pipe cannot be caused; further, the occurrence of the condition of nonuniform pore wall of the prefabricated hollow slab cannot be caused; identically, if the pipe wall rigidity of the hollow pipe is sufficient for supporting a concrete casting load, the arrangement of the support core pulling mold is not needed, and the effect of uniform pore wall of the hollow slab can also be achieved; under the condition of the same materials, the rigidity of the pore-forming pipe can be reinforced, so that the deformation cannot easily occur during the concrete casting; and after the application, the integral quality of the prefabricated hollow slab can be improved.
