Abstract
The invention provides a prefabricated hollow slab core-buried pore-forming tube. The prefabricated hollow slab core-buried pore-forming tube comprises a tube body which is a penetrating hollow tube, and the tube body is formed by assembling multiple sheet bars. In this way, when the tube body is the penetrating hollow tube which is applied to the interior of a prefabricated hollow slab, the ends of the hollow tube are in a penetrating mode, the penetrating hollow tube better facilitates producing of the prefabricated hollow slab through a vertical mold, if a support core-pulling mold is further arranged in the hollow tube, after concrete pouring is completed, the support core-pulling mold is pulled out, and therefore the thickness of the pore-forming tube wall can be greatly decreased. In addition, due to the fact that the tube body is formed by assembling the multiple sheet bars, transportation and storage of the pore-forming tube are convenient, and transportation and storage in a split mode can save a large amount of space; meanwhile, the sources of the materials of the pore-forming tube are wide, waste construction bamboo and wood formworks can be adopted to be cut, assembled and connected through nails to form the pore-forming tube, or boards such as calcium silicate boards and gypsum boards which are low in cost can be utilized to be cut, assembled and connected to form the pore-forming tube, reduction of the cost of the pore-forming tube is facilitated, and application and promotion are easy.
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 is overall structure, takies larger space during transport, and cost of transportation is higher.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of precast hollow slab to bury core pore-forming pipe, takies larger space, the problem that cost of transportation is higher, thus reduce costs when it can solve the hollow device transport in precast hollow slab.
Solution of the present invention is achieved in that a kind of precast hollow slab buries core pore-forming pipe, comprises body, and described body is through hollow section, and described body is assembled by some plates.So, when body is through hollow section, when hollow section is applied in precast hollow slab, its end is through, through hollow section advantageously produces precast hollow slab in formwork erection, to loose core mould, if also arrange support in hollow section after pouring concrete completes, mould of support being loosed core is extracted out, so, significantly can reduce pore-forming tube wall thickness, pore-forming pipe also can not be caused to be out of shape, and then the situation that precast hollow slab hole wall can not be caused uneven occurs.Similarly, if when hollow section tube wall rigidity is enough to support pouring concrete load, does not then need to arrange support and to loose core mould, can reach the uniform effect of hollowcore slab hole wall yet.In addition, described body is assembled by some plates, the transport of pore-forming pipe is deposited conveniently, deposit with split state and transport and can save large quantity space, meanwhile, it is extensive that pore-forming pipe makes material source, pore-forming pipe is connected into nail again after can adopting discarded construction bamboo wooden form cutting, or can also be used as the assembled pore-forming pipe that connects into after this cheap plate cutting such as calcium silicate board with microporous, gypsum plank, be conducive to reducing pore-forming pipe cost, be easy to apply.
Another technical scheme of the present invention is, on above-mentioned basis, outer surface of tube body to be provided with at least one fin, and described fin is longitudinally arranged at tube surfaces.So, also fin is provided with at the external surface of body, in the process making precast hollow slab, fin can play the effect of supporting and location, the situation preventing hollow section from causing hollowcore slab internal construction and project organization not to conform at mould internal shift occurs, fully ensure that the quality of precast hollow slab.In addition, when fin is longitudinally arranged at tube surfaces, in the process making precast hollow slab, the fin longitudinally arranged can also play and block shaping effect, prevent the concrete of precast hollow slab both sides completely through, serve the effect cutting off concrete heat bridge, increase the hollow rate of precast hollow slab further.
