II. Reinforcement cage welding: The type, grade, specification and quantity of load-bearing reinforcement must meet the design requirements. The formed dimensions of the reinforcement skeleton of members and the construction of structural nodes shall meet the design and specification requirements. The type, grade, specification and quantity of load-bearing reinforcement must meet the design requirements. The formed dimensions of the reinforcement skeleton of members and the construction of structural nodes shall meet the design and specification requirements. The connection method of longitudinal load-bearing reinforcement shall meet the design requirements. Within the same member, reinforcement splices should preferably be staggered; in the connection zone (35 times D and not less than 500 mm), the percentage of spliced area of longitudinal load-bearing reinforcement shall not exceed 50%.

　　III. Reinforcement spacing: During reinforcement cage fabrication, the type, grade, specification and quantity of reinforcement must meet the design requirements; the allowable deviation of stirrup spacing or spiral reinforcement pitch is ±20 mm; during reinforcement cage fabrication, the allowable deviation of the reinforcement cage diameter (outer dimension of main reinforcement) is ±10 mm, and the allowable deviation of the reinforcement cage installation depth is ±100 mm.
