H. outrigger is removed；
In described step A, Prefabricated L-shaped ladle includes following operation:
1. making L-type steel semi-finished product:
The spiral bending using bar diameter d >=14mm is fabricated to minor face length >=200mm, the long length of side >=300mm at an angle of 90
L-type steel semi-finished product, the radius of curvature R of spiral is more than the bar diameter d of 4 times；
Or use band steel or square steel bending to be fabricated to L-type steel half one-tenth of minor face length >=200mm, the long length of side >=300mm at an angle of 90
Product；
Or directly use angle steel to be cut into the L-type steel semi-finished product of minor face length >=200mm, the long length of side >=300mm；
The longest limit agnail or crotch:
The long edge point of L-type steel semi-finished product is welded round steel and becomes agnail, or by lower end, the long limit crotch of L-type steel, prepare L-type steel；
Being connected with outrigger by wall-connecting piece described in described step E includes following operation:
1. by the minor face firm welding of one end of wall connecting rod Yu L-type steel；
2. the other end steel tube fastener of wall connecting rod is connected with the vertical rod of outrigger；
Following operation is also included: 3. by the little horizontal stroke of one end of adjustable screw Yu outrigger after the of described step E 2. procedure
Bar is fixing to be connected, and is held out against on main body reinforced concrete structure end face by the other end of adjustable screw, makes main body reinforced concrete structure
End face bears horizontal pressure force, and L-type steel bears horizontal pull, and the weld seam between wall connecting rod and L-type steel bears vertical force；
Or described step A also includes operation: by the minor face firm welding of one end of wall connecting rod Yu L-type steel；And
Being connected with outrigger by wall-connecting piece described in step E includes following operation:
1. the other end steel tube fastener of wall connecting rod is connected with the vertical rod of outrigger；
2. it is connected fixing for the little cross bar of one end of adjustable screw and outrigger, and the other end of adjustable screw is held out against is leading
On body reinforced concrete structure end face, making main body reinforced concrete structure end face bear horizontal pressure force, L-type steel bears horizontal pull, wall connecting rod
And the weld seam between L-type steel bears vertical force.
