beneficial effect:
1. the present invention has avoided exposing between prefabricated units the method with mechanical connection that is welded to connect of connecting reinforcement thoroughly, by simple reinforcing bar binding, just can realize the reliable connection between prefabricated units, can eliminate the potential safety hazard that reinforcing bar produces when being welded to connect with mechanical connection, guarantee construction operation personnel's safety.Housing industrialization energy-saving and environmental protection, efficient, safe theory and original intention have fully been annotated.
2. the 45 degree bending form closed stirrups that the present invention uses, the power that is decomposed into level and vertical both direction with reinforcing bar and the good cooperative work performance of concrete and the good tensile property of reinforcing bar effectively resist constructure body structure precast wall body junction under external force inner produce laterally and longitudinal shear, avoid prefabricated units tradition connect technique at concrete members delay-pour joint place laterally, the disadvantage of longitudinal shear resistance scarce capacity, significantly reduce building destruction under external force.
3. the present invention arranges shearing resistance shearing groove at the exposed steel bar root of precast concrete body of wall, strengthens the shear resistance between precast concrete and cast-in-situ concrete interface, reduces building destruction under external force.
4. the present invention, anti-shear steel plate being set between the exposed steel bar of precast concrete body of wall or increasing the reinforcement ratio between interface, strengthens the shear resistance between precast concrete and cast-in-situ concrete interface, reduces building destruction under external force.
5. the present invention provides possibility for changing existing highrise building monobloc cast technique completely, and construction technology is simple, and precast wall body is realized and being made and maintenance on streamline, can greatly improve speed of application, reduces costs, and saves construction fund.
