Abstract
The invention discloses a ribbed reinforced concrete prefabricated slab, which comprises a reinforced concrete bottom slab (1) and a T-shaped longitudinal rib (2). A large hole (4) is formed in the middle of a web (3) of the T-shaped longitudinal rib (2); a small hole (5) is formed on the lower part or the large hole (4) is formed in the middle and small holes (5) are formed on the upper and lower parts; the height of the large hole (4) is more than or equal to 2/3 of the height h of the web (3); and the height of the small hole (5) is less than or equal to 1/2 of the height h of the web (3). The ribbed reinforced concrete prefabricated slabs are assembled into a whole floor slab; a transverse perforated steel bar (9) is arranged inside the small hole (5) on the web (3) of the longitudinal rib; and a hollow tube (8) vertical to the T-shaped longitudinal rib (2) can be arranged inside the large hole (4). The ribbed reinforced concrete prefabricated slab is particularly suitable for long-span laminated hollow floor covers.
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.This Ribbed Bar concrete prefabricated structural board has the following disadvantages: 1, only have hole in the longitudinal rib bottom, cast-in-situ concrete is poured into when concordant with the longitudinal rib top, transverse reinforcement can not be arranged in Ribbed Bar concrete prefabricated structural board top, when bearing negative moment of backing plate, floor bearing place is easy to destroy; 2, in the large span overlapped hollow floor system, this Ribbed Bar concrete prefabricated structural board is difficult for arranging hollow section.
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 object of the present invention is achieved like this, a kind of Ribbed Bar concrete prefabricated structural board, comprise reinforced concrete floor, the vertical rib of T shape, there is macropore the web centre that the invention is characterized in the vertical rib of described T shape, aperture is arranged at the bottom, and perhaps middle have macropore, and aperture is all arranged at top, bottom, the height of macropore is more than or equal to 2/3 of web height h, and the height of aperture is less than or equal to 1/2 of web height h.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.In the construction of large span overlapped hollow floor system, can arrange the cross-perforating reinforcing bar in the aperture of web upper and lower, arrange in the aperture 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 aperture of top, and the macropore in the middle of the web can be used to arrange the hollow section perpendicular to vertical rib direction.
Feature of the present invention also is described macropore for circular or oval, and aperture 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.
Feature 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 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 also is on the described prefabricated panels with ribbing one or more than one vertical ribs are 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, the build-in between prefabricated panels with ribbing and the concrete folding layer, improve stress performance, the overall performance of superimposed superstructure.
