Description
Technical field:
The present invention relates to the realm of building construction, specifically refer to a kind of reinforced concrete sandwich hollow superstructure.
Background technology:
At present, the floor spiced by steel reinforced concrete of domestic employing can bear bidirectional load, does not need on-the-spot formwork, and cost is low, and lifting, transportation are easily.Publication number be CN101831976A patent disclosure a kind of prefabricated steel rib bottom plate one concrete overlapped hollow floor system, comprise band reinforcing bar rib precast concrete base plate, vertical reinforcing bar rib, hollow mould carriage, hollow mould top board, cast-in-place overlapping layers concrete, this building cover structure is to place square hollow mould on band reinforcing bar rib precast concrete base plate, reproduction is watered the overlapping layers concrete and is formed overlapped hollow floor system, and this superstructure has that bearing capacity is big, anti-seismic performance good, can increase advantage such as floor headroom.But hollow mould directly is placed on the base plate, during cast-in-place overlapping layers concrete, concrete only with the side and the end face bonding of hollow mould, with the bottom surface of hollow mould bonding not, make that the overall performance of this overlapped hollow floor system is bad.Simultaneously, the height of the hollow mould top board in this overlapped hollow floor system is not less than the height of reinforcing bar rib, and during cast-in-place overlapping layers concrete, hollow mould may be subjected to concrete buoyancy and to come-up, bring very big inconvenience to construction like this.
Summary of the invention:
The object of the present invention is to provide a kind of reinforced concrete sandwich hollow superstructure, advantage such as this reinforced concrete sandwich hollow superstructure has that overall performance is good, feed consumption is few, it is light to estimate one's own ability, easy construction, stress performance are good.
The object of the present invention is achieved like this, a kind of reinforced concrete sandwich hollow superstructure, comprise prefabricated panels with ribbing, cast-in-situ concrete overlapping layers, hollow section, transverse reinforcement, prefabricated panels with ribbing comprises base plate and vertical rib, vertical rib is made up of the web and the edge of a wing, the invention is characterized in that the hollow section in the described overlapped hollow floor system is arranged between the adjacent vertical rib web perpendicular to vertical rib direction, the hollow section end is positioned under the vertical rib edge of a wing.The length of hollow section is less than the distance between the adjacent vertical rib web, greater than the distance between the adjacent vertical rib edge of a wing, hollow section is placed on the base plate of prefabricated panels with ribbing, hollow section is between adjacent vertical rib web, the end is positioned under the vertical rib edge of a wing, during the fluid concrete overlapping layers, because blocking of the vertical rib edge of a wing arranged, hollow section can not come convenient construction by emersion.Place hollow section in the superimposed superstructure, can save concrete, alleviate floor deadweight, hollow section arranges perpendicular to vertical rib direction, effectively the stress performance of raising overlapped hollow floor system, pour into a mould the overlapping layers concrete after, can form the bidirectional stress overlapped hollow floor system.
Feature of the present invention is that also the vertical rib in the end of described prefabricated panels with ribbing is a rectangular fin, and the central longitudinal rib is a T shape rib.The vertical rib of T shape has bigger rigidity, can prevent the antiarch of base plate under the prestressed reinforcement effect, is applicable to the construction of the superimposed superstructure of large span.When arranging that perpendicular to vertical rib direction hollow tubular becomes overlapped hollow floor system, if the vertical rib total length of prefabricated panels with ribbing is a T shape rib, hollow section is difficult for arranging, vertical rib end is set to rectangular fin, vertical rib top does not have the edge of a wing to block, hollow section can be placed on the base plate of prefabricated panels with ribbing in the middle of the adjacent rectangle rib of end, hollow section is moved to correct position, with securing member hollow section is fixed on the prefabricated panels with ribbing, the fluid concrete overlapping layers forms the reinforced concrete sandwich hollow superstructure again.
Feature of the present invention is that also the web bottom of described vertical rib has cross through hole hole or upper and lower that the cross through hole hole is all arranged.Can arrange transverse reinforcement in the hole of web upper and lower, arrange in the hole of bottom that transverse reinforcement can improve the cracking resistance and the stress performance of superimposed superstructure, the layout transverse reinforcement can be resisted the hogging moment at superimposed superstructure bearing place effectively in the hole of top, improves the stress performance of superimposed superstructure.
Feature of the present invention is that also described hollow section is fixed on the prefabricated panels with ribbing by securing member.Hollow section is placed in the middle of the adjacent rectangle rib of end on the base plate of prefabricated panels with ribbing and after moving to correct position, by securing member hollow section is fixed on the prefabricated panels with ribbing, like this, during the fluid concrete overlapping layers, hollow section can not move, and brings great convenience to construction.
Feature of the present invention is that also the form of fracture of described hollow section is for circular.During the fluid concrete overlapping layers, concrete can flow to the downside of circular hollow tube, wraps hollow section, like this concrete folding layer and hollow section can bond better, good integrity.
Feature of the present invention is that also there is plug the end of described hollow section.End at hollow section is provided with plug, blocks the hole of hollow section end, and during the fluid concrete overlapping layers, concrete just can not flow in the hollow section.
Feature of the present invention also is on the edge of a wing of described vertical rib connecting reinforcement is arranged.Behind the concreting overlapping layers, connecting reinforcement and concrete folding layer bonding, build-in make the collaborative work between prefabricated panels with ribbing and the concrete folding layer stronger, and stress performance, the globality of superimposed superstructure are better.
Feature of the present invention is that also described hole is rectangle, circle, square, oval, triangle, polygon or arc.The form of hole can be selected flexibly according to reality use and manufacture craft, is convenient to produce and actual the use.
