Abstract
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.
Description
Technical field
The present invention relates to a kind of building unit, particularly a kind of precast hollow slab buries core pore-forming pipe.
Background technology
China's Urbanization Construction is fast-developing, and construction scope ranks first in the world.Current, industrialization of construction industry is extremely urgent, and builing industry green construction transition, energy-saving and emission-reduction in building course, manufacture the precast hollow slab with superior structural performance, extremely need in order to build assembled architecture.
At present, the reinforced concrete floor of domestic employing has cast-in-situ floor and precast hollow slab floor, cast-in-situ floor good integrity, but needs on-the-spot formwork, then concreting, construction period difficulty is large, and template loss is large, and cost is high, and prefabricated building hollowcore slab does not need on-the-spot formwork, short construction period, cost is low, is therefore widely used in all kinds of building.
Such as, be: in the application documents of CN201320705360.2 that disclose a kind of full prefabricated hollow floor, comprise floor main body, floor main body comprises bottom, hollow device and top layer, is hollow device between bottom and top layer at number of patent application; Bottom is that the baseplate reinforcing bar of layer of concrete and top colligation thereof is formed; Top layer is roof steel bar, and concreting layer is formed.This full prefabricated hollow floor is owing to forming cavity at intralamellar part, and alleviate the weight of floor self, comparing laminated floor slab does not also need second pouring, environmental protection and save the duration, but the hollow device of this floor to there is hollow device rigidity strong, easily damaged situation.
