Method for preparing concrete-filled steel tubular edge-constrained laminated shear wall

A method for preparing a concrete-filled steel tubular edge-constrained laminated shear wall, comprising the following steps:

• S1:
• manufacturing a reinforcing steel mesh for an interior wythe board according to a design size of an interior wythe board, and fixing connectors to the reinforcing steel mesh for the interior wythe board;
• S2:
• placing the reinforcing steel mesh for the interior wythe board and the connectors on a production pallet as a whole, and enabling the connectors to be above the reinforcing steel mesh for the interior wythe board, erecting an interior wythe board mold, pouring interior wythe board concrete, and removing the interior wythe board mold after the concrete is cured to a specified strength;
• and
• S3:
• manufacturing a reinforcing steel mesh for an exterior wythe board according to a design size of an exterior wythe board, arranging rectangular steel tubes on both sides of the reinforcing steel mesh for the exterior wythe board, and welding both ends of horizontal steel bars of the reinforcing steel mesh for the exterior wythe board to the rectangular steel tubes;
• wherein the design width of the interior wythe board is smaller than that of the exterior wythe board by a set value;
• S4:
• welding supporting members at set positions on outer surfaces of inner side walls of the rectangular steel tubes, placing the reinforcing steel mesh for the exterior wythe board and the rectangular steel tubes on the production pallet as a whole, erecting end formworks for the exterior wythe board, using the rectangular steel tubes as side formworks for the exterior wythe board, and pouring exterior wythe board concrete;
• S5:
• flipping the interior wythe board and the connectors as a whole by 180°, placing both ends of the interior wythe board in the width direction on the supporting members, and anchoring the connectors into the poured exterior wythe board concrete, vibrating and compacting the exterior wythe board concrete, and removing the end formworks for the exterior wythe board after the concrete is cured to a specified strength;
• wherein arrangement positions of the supporting members meet a requirement that a top surface of the interior wythe board is flush with top surfaces of the rectangular steel tubes after both ends of the interior wythe board in the width direction are placed on the supporting members;
• S6:
• filling gaps between the interior wythe board and the rectangular steel tubes with slurry for gap sealing, thus completing the preparation of the concrete-filled steel tubular edge-constrained shear wall.
