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; and at least one transverse pipe transversely penetrating through the pipe body is arranged on the pipe wall of the pipe body. Therefore when the pipe body is the penetrated hollow pipe, and the hollow pipe is applied into a prefabricated hollow slab, the end part of the hollow pipe is penetrated; the penetrated hollow pipe is favorable for the prefabricated hollow slab production by formwork erection; and if a support core pulling mold is also arranged in the hollow pipe, after the concrete casting completion, the support core pulling mold is pulled out. Therefore the pipe wall thickness of the pore-forming pipe can be greatly reduced; and the pore-forming pipe deformation cannot be caused. In addition, the at least one penetrated transverse pipe is arranged on the pipe wall of the pipe body; concrete is cast into the transverse pipe; a concrete post body can be formed in the prefabricated hollow slab; the two slab surfaces of the prefabricated hollow slab can be drawn into a whole; the transverse pipe per se can achieve a good support effect on the pore-forming pipe; and the deformation of the pore-forming pipe during the concrete casting can be prevented.
