Described band concealed bracings steel concrete large plate sleeper square steel pipe and X-shaped steel diagonal brace are welded into steel frame by L angle steel, and steel mesh reinforcement and concrete jointly stressed;
Described square steel pipe top tape stiffening rib and stretch into upper strata square steel pipe certain distance;
The jagged reinforcing bar of described corner breach, middle part grooved gap regions has cyclic reinforcing rib;
Described corner breach is overlapped indirectly by connecting reinforcement and breach reinforcing bar, and middle part grooved gap regions is then inserted cyclic reinforcing rib by connecting reinforcement and indirectly overlapped.
Compared with cast-in-situ steel reinforced concrete shear wall structure, the utility model major part component is all prefabricated in the factory productions, the more a small amount of necessary concrete of assembled after-pouring at the scene, and plant produced efficiency is high, and can ensure making precision and quality, environmental protection; With existing prefabricated costruction especially compared with existing prefabricated assembled large panel shear wall structure, the large plate shear wall structure of prefabricated assembled band concealed bracings of the present utility model, its upper and lower vertical node connects more reliable, globality is better, and the formation of steel frame makes supporting capacity significantly improve, effectively be thinned the thickness of shear wall, there is again obvious multiple seismic-proof simultaneously, and can show good under geological process.
