Described stirrup is arranged in the rear joint bar reserving hole of body of wall by pre-buried mode, or stirrup and vertical muscle are tied to and are integrally formed reinforcing cage and are placed in rear joint bar reserving hole.
Described body of wall sidepiece is provided with edge member, joint bar reserving hole after being also provided with in edge member, in rear joint bar reserving hole, is provided with stirrup, and has been evenly arranged vertical muscle inside stirrup, and body of wall top formation overlap joint linkage section is stretched out in vertical muscle upper end.
Described stirrup is arranged in the rear joint bar reserving hole of edge member by pre-buried mode, or stirrup and vertical muscle are tied to and are integrally formed reinforcing cage and are placed in rear joint bar reserving hole.
The material of described stirrup is metal or FRP fibre reinforced composites.
Described stirrup adopts continuous helical stirrup or rectangle hoop.
The inner surface of described rear joint bar reserving hole is matsurface or has shearing resistance groove.
Described rear joint bar reserving hole can adopt continuous penetration type or discontinuous penetration type.
The cross sectional shape of described reserved hollow hole and rear joint bar reserving hole can be circle, rectangle or ellipse.
The cross sectional shape of described body of wall can be yi word pattern, L-type, T-shaped or U-shaped.
The beneficial effects of the utility model:
The utility model, by increasing reserved hollow hole and rear joint bar reserving hole in precast unit body of wall, effectively alleviates the deadweight of precast unit body of wall, can also reduce wall body structure rigidity, reduces geological process, improves heat insulating effect; By arranging stirrup and vertical muscle in rear joint bar reserving hole of the present utility model, when after the pea gravel concreten pouring practice completing joint bar reserving hole after body of wall, the concrete in it can be given in the three dimension stress restraint forces of side direction applying uniformly continous by stirrup, can the concrete lateral deformation of operative constraint, and suppress the flexing of vertical muscle, significantly improve the concrete compression set ability in body of wall two ends, thus increase the bearing capacity of body of wall, improve the overall anti-seismic performance of wall body structure.
