Description
Technical field:
The present invention relates to the realm of building construction, specifically refer to a kind of Ribbed Bar concrete prefabricated structural board.
Background technology:
At present, floor spiced by steel reinforced concrete can bear bidirectional load, and good integrity does not need on-the-spot formwork, and cost is low, and lifting, transportation are easily.Floor spiced precast member for reinforcing bar concrete adopts Ribbed Bar concrete prefabricated structural board (number of patent application 03227765.2) usually; Have hole in precast member for reinforcing bar concrete longitudinal rib bottom; Transverse reinforcement passes the hole of prefabricated units longitudinal rib bottom, connects the polylith reinforced concrete prefabricated structural board.Not enough below this Ribbed Bar concrete prefabricated structural board exists: 1, in the large span overlapped hollow floor system, this Ribbed Bar concrete prefabricated structural board is difficult for arranging hollow section; 2, only have hole in the longitudinal rib bottom, cast-in-situ concrete is poured into when concordant with the longitudinal rib top, and transverse reinforcement can not be arranged in Ribbed Bar concrete prefabricated structural board top, and when bearing negative moment of backing plate, floor bearing place is easy to destroy.
Summary of the invention:
The object of the present invention is to provide a kind of Ribbed Bar concrete prefabricated structural board, this Ribbed Bar concrete prefabricated structural board has that feed consumption is few, in light weight, easy construction, applied widely, advantage such as stress performance is good.
The objective of the invention is to realize like this, a kind of Ribbed Bar concrete prefabricated structural board comprises reinforced concrete floor, vertical rib, and the end cross-sectional that the invention is characterized in said vertical rib is a rectangle, and the cross section of the mid portion of said vertical rib is a T shape.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 in superimposed superstructure, 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 that vertical rib end is set to rectangular fin; Vertical rib top does not have the edge of a wing to block; Can hollow section be placed on the base plate of prefabricated panels with ribbing in the middle of the adjacent rectangle rib from the end, hollow section is moved to correct position, hollow section is fixed on the prefabricated panels with ribbing with securing member; The fluid concrete overlapping layers forms overlapped hollow floor system again.
Characteristic of the present invention is that also the web bottom of the vertical rib of said T shape has cross through hole hole or upper and lower that the cross through hole hole is all arranged.Can arrange the cross-perforating reinforcing bar 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.
Characteristic 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 according to reality use and manufacture craft flexibly, is convenient to produce with actual and uses.
Characteristic of the present invention also is on the vertical rib edge of a wing of described prefabricated panels with ribbing connecting reinforcement is arranged.Behind the concreting overlapping layers, connecting reinforcement and concrete folding layer bonding, build-in make the collaborative work property between prefabricated panels with ribbing and the concrete folding layer stronger, and stress performance, the globality of superimposed superstructure are better.
Characteristic of the present invention also is on the described prefabricated panels with ribbing vertical rib more than is arranged.Many vertical rib can further improve prefabricated panels rigidity with ribbing; When assembly unit integral body floor; Many vertical ribs on the prefabricated panels with ribbing can strengthen bonding, build-in between prefabricated panels with ribbing and the concrete folding layer, improve stress performance, the overall performance of superimposed superstructure.

The specific embodiment:
Below in conjunction with accompanying drawing the present invention is described further.
The present invention is shown in accompanying drawing 1～7, and a kind of Ribbed Bar concrete prefabricated structural board comprises reinforced concrete floor 1, vertical rib 2, and the end cross-sectional that the invention is characterized in said vertical rib 2 is a rectangle, and the cross section of the mid portion of said vertical rib 2 is a T shape.Fig. 1, Fig. 2 are prefabricated panels structural representation with ribbing.Rectangular fin is placed into the base plate sketch map to Fig. 3 from the end for hollow section; When in superimposed superstructure, arranging that perpendicular to vertical rib 2 directions hollow section 8 forms overlapped hollow floor systems; Vertical rib 2 ends of prefabricated panels with ribbing are set to rectangular fin, and vertical rib 2 tops do not have the edge of a wing 5 to block, and hollow section 8 is placed on the base plate 1 of prefabricated panels with ribbing in the middle of the adjacent rectangle rib of end; Make hollow section 8 move to correct position; With securing member 9 hollow section 8 is fixed on the prefabricated panels with ribbing, the fluid concrete overlapping layers forms overlapped hollow floor system again.
Characteristic of the present invention is that also web 3 bottoms of the vertical rib 2 of said T shape have cross through hole hole 4 or upper and lower that cross through hole hole 4 is all arranged.Among Fig. 1, Fig. 2, Fig. 3, all there is cross through hole hole 4 vertical rib web 3 upper and lowers, hole 4 interlaced arrangement of upper and lower.Fig. 4 is for indulging the panels structural representation prefabricated with ribbing that cross through hole hole 4 is arranged at rib web 3 bottoms, and Fig. 5 is prefabricated another embodiment of panels with ribbing, and among the figure, all there is hole 4 vertical rib web 3 upper and lowers of prefabricated panels with ribbing, and hole is corresponding about in the of 4.
