step one, prefabricating a middle pouring system
Step 1.1, welding all the first vertical reinforcements (13) and the transverse reinforcements (14) to form two reinforcement meshes, and sleeving and welding the truss reinforcements (16) on the two reinforcement meshes in the process; then bending two ends of the transverse steel bar (14) towards another steel bar mesh respectively, welding the rectangular support frame, and forming a steel bar cage by the steel bar mesh and the truss steel bar (16);
step 1.2, arranging the through holes (12 a) on the frame plates (12) corresponding to each rectangular support frame, and then respectively sleeving the two frame plates (12) on the left side and the right side of the reinforcement cage to enable the frame plates (12) to be abutted against the first vertical reinforcements (13) positioned on the outermost sides;
finally, the middle panel (11) is placed on two sides of the reinforcement cage, welded with the two side frame plates (12) and the positions corresponding to the truss reinforcements (16), and reserved with the outer side abutting strips (15);
step 1.3, respectively welding the second vertical steel bars (23) on the penetrating ends of the rectangular supporting frames corresponding to each steel bar net piece;
step two, prefabricating an end part pouring system
-connecting the end panel (21) and the flap (22) in position, and reserving the inner abutment strip (24);
step three, assembling a shear wall pouring system
Assembling an end pouring system and a middle pouring system, enabling an end panel (21) and a middle panel (11) to correspond to each other, enabling the inner side abutting strip (24) and the outer side abutting strip (15) to be mutually attached and abutted, and finally welding and sealing a vertical gap between the edge of the outer side abutting strip (15) and the end panel (21);
step four, pouring
And after the assembled shear wall pouring system is hoisted in place, pouring concrete into the middle pouring area and the end pouring areas, and forming after curing.
