Abstract
The invention discloses an overlaid plate type concrete shear wall and a longitudinal connecting method. Longitudinal connection of existing overlaid plate type concrete shear walls is achieved only by arranging rear steel dowels on rear pouring parts, rebars are not easy to position, rebar displacement occurs easily during concrete pouring, and structural integrity can not be guaranteed easily. The overlaid plate type concrete shear wall comprises a prefabricated overlaid type concrete shear wall component, wherein the prefabricated overlaid type concrete shear wall component comprises two layers of prefabricated floor slabs (1), cast-in-place concrete is arranged between the prefabricated floor slabs, longitudinal rebars (2), horizontal rebars (3) and reinforcing ribs (4) are pre-buried in the prefabricated overlaid type concrete shear wall component, the prefabricated floor slabs and the cast-in-place concrete are connected into a whole through lattice rebars (5), and the lattice rebars (5) are connected with the longitudinal rebars and the horizontal rebars in a welding mode. The overlaid plate type concrete shear wall and the longitudinal connecting method are used for connection between prefabricated concrete structural components through longitudinal rebars.

beneficial effect:
1. the pre-buried constraint reinforcing bar of reserving hole of the present invention and embedded bar periphery makes concrete form three dimension stress stress state, and concrete compressive property is effectively strengthened, limited the radially development of internal fissure of concrete, adhesion strength is improved, anchorage reliability strengthens, therefore switching performance is reliable, is applicable to again the construction feature of housing industrialization precast concrete.
2. the pre-buried reinforcing rib of the present invention is when strengthening anchoring effect, make rear insert vertical muscle can with its colligation, make reinforcement location can not be subject to the impact of concreting, the globality of structure is easy to guarantee.
3. the reinforcing bar attended operation that the present invention realizes is simple, and work progress does not need complicated plant equipment and facility, does not also need power consumption.
4. the present invention's construction is easy to guarantee, job site is dry operation substantially, has fully avoided all disadvantages of traditional reinforcing bar connected mode.
5. building course environmental protection and energy saving of the present invention, reduce costs, save construction fund.
