因施工现场场地狭小钢筋加工多为场内加工,对钢筋的制作及成品的堆

放有困难。 3. 施工准备 3.1. 技术准备

熟悉施工图纸,学习有关规范、规程,按规范要求编制钢筋施工方案,包括基础底板、基础反梁、剪力墙、框架柱、框架梁、板钢筋等的加工、绑扎等施工内容。

组织工人学习直螺纹接头的工艺操作、钢筋加工、绑扎等施工工艺标准。 熟悉钢筋直螺纹连接工艺规程及规范要求。

按设计要求放样,检查已加工好的钢筋规格、形状、数量全部正确。 做好抄平放线工作,弹好水平标高线,柱、墙外皮尺寸线。

按设计、规范列出本工程墙柱筋接头锚固一览表(包括错开百分比、错开长度、百分比系数),根据弹好的外皮尺寸线,检查下层预留搭接钢筋的位置、接头百分比、错开长度。如不符合要求时,要进行处理。绑扎前保护层偏位按1:6调正伸出的搭接筋,并将锈蚀、水泥砂浆等污垢清除干净。
