As the preferred embodiment of the method, meeting concreting after both sides shear wall formwork installs, when concrete in shear wall formwork reaches requiring of the dismountable template of codes and standards, take out wall-punching pair-pulling threaded spindle, after removing described shear wall formwork, take out described steel pipe, described plastic pipe is stayed in body of wall.In the prior art of comparing, use concrete inner support bar, the utility model adopts steel pipe to do inner support, when dismounting, steel pipe can be taken out and plastic pipe is stayed in body of wall, and steel pipe only needs can realize and repeatedly can have enough to meet the need use after disposable production, save great amount of cost, economic effect is obvious.
In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are:
1, compare in prior art by the reinforcing bar inner support of concrete inner support bar or welding, the utility model adopts steel pipe to do inner support, when dismounting, steel pipe can be taken out and plastic pipe is stayed in body of wall, steel pipe only needs can realize and repeatedly can have enough to meet the need use after disposable production, save great amount of cost, economic effect is obvious.
2, the utility model does inner support without welding with steel pipe, and steel pipe good rigidity is specially adapted to thicker shear wall, can ensure the construction quality compared with thick shear-wall.
3, in the utility model, steel pipe is to be enclosed within on wall-punching pair-pulling threaded spindle, and in the shear wall Screw arbor with nut at both-ends hole that wall-punching pair-pulling threaded spindle interts on shear wall formwork, shear wall formwork is without increasing perforate again, simple installation and improved operating efficiency.
4, the utility model construction safety, does not need welding, reduces construction safety risk, reduces and pollutes, and ensures personal safety as well as the property safety, and minimizing accident occurs.
