问题 问答题

某工程项目,采用钢筋混凝土剪力墙结构,施工顺序划分为基础工程、主体结构工程、机电安装工程和装饰工程四个施工阶段。
施工承包单位对该工程的施工方法进行了选择,拟采用以下施工方案。
(1)土石方工程采用人工挖土方,放坡系数为1:0.5,待挖土至设计标高进行验槽,验槽合格后进行下道工序。
(2)砌筑工程的墙身用皮数杆控制,先砌外墙后砌内墙,370mm墙采用单面挂线,以保证墙体平整。
(3)屋面防水分项工程的防水材料进场后,检查出厂合格证后即可使用。
(4)扣件式钢管脚手架的作业层非主节点处的横向水平杆的最大间距不应大于纵距的3/4。
问题1.施工承包单位采用的施工方案有何不妥请指出并改正。
2.针对砌筑工程在选择施工方案时的主要内容包括哪些
3.扣件式钢管脚手架的作业层上非主节点处的横向水平杆宜根据什么来设置间距

答案

参考答案:1.施工承包单位采用的施工方案的不妥之处:
(1)不妥之处:先砌外墙后砌内墙。
正确做法:内外墙同时砌筑。
(2)不妥之处:370mm墙采用单面挂线。

(4)不妥之处:扣件式钢管脚手架的作业层非主节点处的横向水平杆的最大间距不应大于纵距的3/4。
正确做法:作业层非主节点处的横向水平杆的最大间距不应大于纵距的1/2。
2.砌筑工程在选择施工方案时的主要内容
(1)砌体的组砌方法和质量要求。
(2)弹性及皮数杆的控制要求。
(3)确定脚手架搭设方法及安全网的挂设方法。
3.扣件式钢管脚手架作业层上非主节点处的横向水平杆,宜根据支撑脚手板的需要设置间距。
