(2) present apparatus can be repeatedly used in turn；
(3) present apparatus installation and dismounting are convenient, and speed of application is fast；
(4) two pieces of shear walls adjacent at inner corner trim can be used simultaneously English truss and carry out unilateral formwork；
(5) Surface Quality of Concrete is good after being molded.
In conclusion the utility model reinforces supporting way reasonable stress, reinforcing is solid and reliable, and rigidity is big, and deformation is small；It can
Repeatedly it is used in turn；Installation and dismounting are convenient, and speed of application is fast；At inner corner trim two pieces of adjacent walls can be used simultaneously English truss into
The unilateral formwork of row；Surface Quality of Concrete is good after molding.
