Wherein above-mentioned hollow round pipe 3 can be arranged in the top of the first steel bar layer 2 in rectangular array, guarantee the equal of load-bearing stress
Even property.
In order to prevent when casting concrete, concrete is flowed into the internal cavities in hollow circular tube road 3, is implemented as optional
Mode, the both ends in hollow circular tube road 3 are provided with seal head, and seal head closes the both ends port in hollow circular tube road 3.
Wherein, the shape, structure of seal head is unlimited, can equally desulfurized gypsum or ardealite preparation again；Or it is pre-
It is directly integrally formed when hollow circular tube road 3 processed using mold.
As optional embodiment, the height of the concrete 5 poured be greater than 2 to the second steel bar layer 4 of the first steel bar layer it
Between thickness.
It should be understood that referring to Fig.1 and Fig. 4, after casting concrete, concrete 5 is filled in the interior of the first steel bar layer 2
Between portion, multiple hollow circular tube roads 3, the inside of the second steel bar layer 4 and between layers so that two steel bar layers and clamping
The 3 layers of formation in hollow circular tube road, one entirety.And concrete 5 protrudes from the surface of two steel bar layers, above-mentioned setting enables to
After concrete 5 solidifies, form removal 1 can't see exposed steel bar layer or hollow circular tube road 3, more beautiful, while the first steel
Muscle layer 2 and the second steel bar layer 4 are not easily to fall off, have better anti-seismic performance.
As optional embodiment, referring to Fig. 5, Fig. 5 is the signal in the hollow circular tube road connecting with heating system pipe
Figure.The end of adjacent hollow round pipe 3 is connected by bend pipe 8, and bend pipe 8 is hollow structure, and multiple hollow circular tube roads 3 are by more
A bend pipe 8 is connected to；Hollow circular tube road 3 positioned at floor avris is connect with the pipeline of heating system.
Above structure is more suited to rural area, and is unsuitable in the building high level in city.It, can be by above-mentioned hollow circular tube in rural area
Road 3 is linked together (such as Fig. 5) by bend pipe 8, and by between hollow circular tube road 3 and the pipeline of heating system, heating system can be with
For stove or other heating devices.Play the role of heating between hot gas capable of being riddled floor by heating furnace body.
On the bearing plate of floor, in order to enhance load-bearing property, as optional embodiment, the quadrangle of floor passes through knot
Structure column 6 supports.Preferable scheme is that the surrounding of floor is additionally provided with load-bearing cage reinforcing bar 7.Above structure can refer to Fig. 2, Fig. 3
And Fig. 5, above structure are suitably applied on the load-bearing plate structure between floor, when above-mentioned floor is on wall or partition
When, then no setting is required structural column 6 or load-bearing cage reinforcing bar 7.
In order to set concealed for electric power, electric wire pipeline, as optional embodiment, be embedded in floor electric power,
Telecommunication line or water pipe.
Above-mentioned prefabricated hollow round pipe cast-in-place concrete building floor provided by the invention, combines prefabricated board and Bars In Poured Concrete Slab
The advantages of, reinforcing bar or concrete raw material can be saved, while the structure in hollow circular tube road has soundproof effect, thermal insulation property
Benefit, the structure of arc weight-bearing surface and the globality by the cast-in-place formation of coagulation, so that load-bearing property is more preferable.
In the description of this specification, specific features, structure or feature can in any one or more embodiments or
It can be combined in any suitable manner in example.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Those familiar with the art in the technical scope disclosed by the present invention, can easily think of the change or the replacement, and should all contain
Lid is within protection scope of the present invention.Therefore, protection scope of the present invention should be based on the protection scope of the described claims.
