国家标准GB50204 -92《混凝土结构工程施工及验收规范》第3.5.1条规定 :一、钢筋的交叉点应采用铁丝扎牢 ;二、板和墙的钢筋网 ,除靠近外围两行钢筋的相交点全部扎牢外 ,中间部分交叉点可间隔交错扎牢 ,但必须保证受力钢筋不产生位置偏移 ;双向受力的钢筋 ,必须全部扎牢。板和墙的钢筋网绑扎的主要目的是 ,固定钢筋的正确位置 ,保证钢筋不产生位置偏移。从这个要求看 ,无论是受 National Standard GB50204 -92 “Construction and acceptance of concrete structures,” the provisions of Article 3.5.1: First, the bar should be used at the intersection of steel wire tie; Second, the plate and the wall of the network, in addition to the two outer rows near the intersection of steel Point all jail, the middle part of the intersection may be staggered, but must ensure that the reinforced bar does not produce position shift; two-way force of steel, all must be jailed. The main purpose of banding the rebar of the slab and wall is to fix the correct position of the rebar so as to ensure that the rebar does not generate a position offset. From this requirement, no matter what it is
