The novel precast reinforced concrete shear wall comprises a plurality of spliced prefabricated panels, double-layer two-way-reinforcement reinforced concrete is arranged inside the prefabricated panels, and a rectangular frame formed by four case-shaped section shape steels in end-to-end connection is arranged on the periphery of the prefabricated panels. Reinforced concrete is poured into the case-shaped section shape steels, an inner side wing edge of each case-shaped section shape steel is used for fixing horizontal steel bars and vertical steel bars of the prefabricated panels, the outer side wing edge of each case-shaped section shape steel is provided with bolt holes, and each two prefabricated panels are spliced through high-strength bolts on construction site. The novel precast reinforced concrete shear wall is clear in concept, fine in overall performance, convenient in splicing, reliable in performance and beneficial to large-scale application and popularization.
Description
Technical field
The utility model relates to the civil engineering work technical field of structures, particularly a kind of novel prefabricated reinforced concrete shear wall.
Background technology
Shear wall structure is a kind of topmost lateral resisting system that high building structure adopts, but most of shear wall structure is the cast-in-place shear wall structure, and prefabricated shear wall structure system does not also reach widely to be used.Compare cast-in-place structural, the advantage of precast construction is to help building the industrialization of production, reduce on-the-spot wet trade, accelerate construction speed, reduction of erection time, but that its shortcoming is a globality is relatively poor with respect to cast-in-place structural, and Here it is, and prefabricated shear wall structure does not reach one of major reason of large-scale application, the scene splicing that to also have a factor that causes precast construction not popularize be precast construction is complicated, and performance is difficult for guaranteeing.
Therefore, it is good to develop a kind of overall performance, and splicing is convenient, and the novel prefabricated reinforced concrete shear wall of splicing dependable performance just seems both urgent and meaningful especially.
Summary of the invention
In order to overcome the weak point that present existing prefabricated reinforced concrete shear wall overall performance is relatively poor and splicing is complicated, the utility model provides a kind of overall performance good, and splicing is convenient, the novel prefabricated reinforced concrete shear wall of splicing dependable performance.
The technical scheme that the utility model adopted is a kind of novel prefabricated reinforced concrete shear wall, it is formed by the polylith splicing prefabricated wallboard, the inside of prefabricated panel is the steel concrete of double-layer double-direction arrangement of reinforcement, it around it rectangular shaped rim that four box section shaped steel link together from beginning to end and form, the inside fluid concrete of box section shaped steel, the inboard edge of a wing of box section shaped steel is used for fixing the horizontal distribution reinforcing bar and the vertical distribution reinforcement of prefabricated panel, the outer side wing edge of box section shaped steel has bolt hole, is stitched together by high-strength bolt between any two at the building-site prefabricated panel.
The inboard edge of a wing of described box section shaped steel with face that concrete contacts on should weld shear connector.
The web outside of described box section shaped steel is provided with stiffening rib.
The horizontal distribution reinforcing bar of described prefabricated panel and vertical distribution reinforcement can be fixed on the inboard edge of a wing of box section shaped steel by the mode of perforation plug welding, also can be at the end machining screw thread of horizontal distribution reinforcing bar and vertical distribution reinforcement, by the inboard edge of a wing of fixed by nut at box section shaped steel.
Described shear connector is peg or steel plate.
The utlity model has following remarkable advantage:
(1) overall performance is good.Compare present existing prefabricated reinforced concrete shear wall, advantage of the present utility model is exactly to connect by high-strength bolt between the prefabricated panel, so overall performance is good.
(2) splicing is convenient.Prefabricated panel is in advance good in factory process, transports to on-the-spot back directly with high-strength bolt splicing prefabricated wallboard together, so splicing easily, construction easily.
(3) splicing dependable performance.Because connecting method adopts the high-strength bolt connected mode of widespread usage in the steel work, so the splicing performance between the prefabricated panel is very reliable.
(4) anti-seismic performance is good.Be box section shaped steel around the prefabricated panel, the distortion that the rectangular shaped rim that box section shaped steel is formed can well confined concrete has strengthened the deformability of prefabricated panel, so ductility is good, anti-seismic performance is strong.
The utility model can be used in the various building structure, such as shear wall structure, frame shear wall structure in the tubular construction, not only helps the industrialization of building industry, and overall performance is good, splicing is convenient, connects reliably, and anti-seismic performance is good, significant, will be widely used in the civil engineering work technical field of structures.
