Abstract
The invention provides a reinforced concrete precast component which comprises a concrete bottom plate and longitudinal ribs. The longitudinal ribs are arranged on the concrete bottom plate, reinforcing ribs are arranged at the junctures of the concrete bottom plate and the longitudinal ribs. The longitudinal ribs comprise end portion longitudinal ribs and middle longitudinal ribs, wherein the end portion longitudinal ribs are arranged at the upper ends of the middle longitudinal ribs, the end portion longitudinal ribs are provided with reinforcing connecting ribs, and reserved holes are formed in the upper portions of the middle longitudinal ribs. Fine turning screws are arranged in the reserved holes and fixed by nuts, openings are arranged in the lower portions of the middle longitudinal ribs, and rib middle membrane cavity pouring concrete transverse ribs which are connected with rebar longitudinal ribs are arranged in the openings. The reinforced concrete precast component has the advantages of enhancing the bonding and building in of a prefabricated rib component plate and a concrete overlapping layer, and improving the stress performance and whole performance of an overlapped floor system.
Description
Technical field
The invention belongs to building prefabricated components field, especially relate to precast member for reinforcing bar concrete.
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, transport are easily.Floor spiced precast member for reinforcing bar concrete adopts Prefabricated component board of ribbed reinforced concrete conventionally, have hole in precast member for reinforcing bar concrete longitudinal rib bottom, transverse reinforcement, through the hole of prefabricated units longitudinal rib bottom, connects polylith reinforced concrete prefabricated structural board.Because this Prefabricated component board of ribbed reinforced concrete only has hole in longitudinal rib bottom, cast-in-situ concrete is poured into when concordant with longitudinal rib top, transverse reinforcement can not be arranged in Prefabricated component board of ribbed reinforced concrete top, and in the time bearing negative moment of backing plate, floor bearing place is easy to destroy.
Concrete prefabricated structural board has quality and easily ensures, installs the various feature such as attractive in appearance of convenient, profile, it can be at plant produced concrete prefabricated structural board for building, manufacture concrete prefabricated structural board in factory time, just window frame, pipeline also together can be made, handling can directly be installed on building behind building site, can greatly accelerate the speed of building operations, and quality can ensure, therefore more and more liked by architect.In recent years, concrete prefabricated structural board is in installation process, between adjacent concrete prefabricated structural board, can have larger gap, the gap between concrete prefabricated structural board may cause building to produce seepage later, and it is attractive in appearance to destroy the structure of building.And at present large-scale concrete prefabricated structural board is difficult to accomplish reducing of gap between adjacent concrete prefabricated structural board.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of precast member for reinforcing bar concrete, especially has the advantages such as feed consumption is few, lightweight, easy construction, applied widely, stress performance is good.
For solving the problems of the technologies described above, the technical solution used in the present invention is: precast member for reinforcing bar concrete, comprise concrete floor, vertical rib, described concrete floor is provided with vertical rib, described concrete floor and described vertical rib intersection area are provided with reinforcing rib, described vertical rib comprises that end indulges rib, central longitudinal rib, the vertical rib in described end is arranged at central longitudinal rib upper end, the vertical rib in described end is provided with reinforced company's rib, described central longitudinal rib top is provided with preformed hole, described preformed hole is provided with fine setting screw rod, described fine setting screw rod is fixed by nut, the bottom of described central longitudinal rib is provided with hole, described hole is provided with connecting reinforcement, in the rib of described vertical rib, concrete cross rib is watered in film chamber.
The upper plane of described concrete floor and the angle of level ground are not more than 45 degree.
In described reinforced company rib, be provided with shaped steel.
Described preformed hole diameter is 50mm.
The beneficial effect that the present invention has is: on concrete floor, be provided with reinforcing rib and vertical rib with vertical rib intersection and be provided with reinforced company's rib the intensity of vertical rib is improved, not easy fracture, damage in work progress; Preformed hole penetrates fine setting screw rod, can up-down adjustment finely tune screw rod, and calibration adjacent plate is proofreaded, control panel gap; Vertical rib, cross rib form cross knot point, the intensity of more effective reinforcement prefabricated units.These prefabricated units have bonding, the build-in that can strengthen between prefabricated panels with ribbing and concrete folding layer, improve the advantage such as stress performance, overall performance of superposed floor.

Detailed description of the invention
As Fig. 1, shown in 2, precast member for reinforcing bar concrete of the present invention, comprise concrete floor 1, vertical rib, concrete floor 1 is provided with vertical rib, concrete floor 1 is provided with reinforcing rib 8 with described vertical rib intersection area, described vertical rib comprises that end indulges rib 2, central longitudinal rib 3, the vertical rib 2 in end is arranged at central longitudinal rib 3 upper ends, the vertical rib 2 in end is provided with reinforced company's rib 6, central longitudinal rib 3 tops are provided with preformed hole 4, preformed hole 4 is provided with fine setting screw rod, described fine setting screw rod is fixed by nut, the bottom of central longitudinal rib 4 is provided with hole 5, hole 5 is provided with connecting reinforcement, in the rib of described vertical rib, concrete cross rib 7 is watered in film chamber.
The upper plane of concrete floor 1 and the angle of level ground are not more than 45 degree.
In reinforced company's rib 6, be provided with shaped steel.
Preformed hole 4 diameters are 50mm.When adjacent plate is installed, penetrate described fine setting screw rod by preformed hole 4, described fine setting screw rod outsourcing water proof rubber pipe box, bolt has water proof rubber pad, by upper and lower fine adjustment screw rod, adjacent plate is calibrated control panel gap.Treat that concrete prefabricated element prestressed stretch-draw completes, bolt can be extracted out from water proof rubber pipe box, to reuse.
The course of work of this example:
The vertical rib 2 in end of described prefabricated panels with ribbing is rectangular fin, and central longitudinal rib 2 is T shape rib.When use, hollow section is placed into the concrete floor 1 of prefabricated member with ribbing in the middle of end adjacent rectangle rib 2, hollow section is moved to correct position, hollow section is fixed on prefabricated panels concrete floor 1 with ribbing with securing member, fluid concrete overlapping layers again, forms overlapped hollow floor system.These prefabricated units have bonding, the build-in that can strengthen between prefabricated panels with ribbing and concrete folding layer, improve the advantage such as stress performance, overall performance of superposed floor.
Above one embodiment of the present of invention are had been described in detail, but described content is only preferred embodiment of the present invention, can not be considered to for limiting practical range of the present invention.All equalization variation and improvement etc. of doing according to the present patent application scope, within all should still belonging to patent covering scope of the present invention.
