鲁班奖工程细部做法经验集锦第一节、基本要求一、项目部要依据本细则并结合工程的具体情况,加强施工技术交底管理,技术交底中应有细部工艺的具体要求.二、加强过程控制和检查监督的力度,发现问题及时解决,检查验收要高标准、严要求,切实把技术交底和细部工艺处理要点落到实处,达到工艺精湛。
三、施工过程中,按标准工艺施工,消除质量通病。
四、每一种细部工艺处理都要先做样板,征得建设单位认可,经质检部门验收合格后方可展开大面积施工。
五、进行细部工艺处理,要求选用技术素质高、认真负责、细心的专业人员做此项工作。
六、工具、材料要提前准备齐全,如勾缝、钻孔的专用工具,橡胶密封条、塑料分格条等。
七、成品、半成品及外购件购置要进货验收,不合格的材料严禁使用。
八、凡没有按细部处理方案施工、不符合规定的一律无条件返工重做。
九、落实各项成品保护措施,防止成品污染和损坏.第二节、细部工艺细则一、主体结构㈠钢筋工程:1。
钢筋绑扎应采取定位措施,柱、剪力墙的钢筋定位卡设置于模板上口;钢筋的混凝土保护层采用专用垫块控制,清水砼柱、墙体结构宜选用与砼颜色一致的塑料卡环,梁、板可以采用混凝土成品垫块。
2.板上、下层钢筋间应设置专用马凳,马凳采用钢筋时,钢筋直径应确保承受荷载不变形,间距不大于1000㎜,梅花形布置。
3。
钢筋绑扎时绑扎结应与最外层钢筋平齐,绑扎丝尾部压向钢筋内侧,钢筋应横平竖直,绑扎牢固。
剪力墙、板钢筋绑扎采用八字扣,柱箍筋绑扎宜采用缠扣,梁上部纵向筋的箍筋绑扎宜采用套扣法绑扎。
绑扎时水平挂线,竖向吊线,控制水平度、垂直度。
4。
墙、柱等竖向构件的外露钢筋在浇筑砼前应采取套好塑料保护管或包裹彩布条等措施,并且在砼浇筑后,及时用布或棉纱沾水将被污染的钢筋擦净,确保钢筋不被污染.5。
钢筋保护层厚度按正偏差控制,提高钢筋防腐蚀能力。
㈡模板工程:1。
模板体系的选择:a)镜面砼:可采用优质木胶合板粘贴pvc板,宜选用塑料模板或成品覆塑板;b)清水砼:建议采用优质覆膜木胶合板或全钢大模板:c)楼梯、洞口:建议采用易装拆的定制钢模板:d) 高层建筑竖向构件、楼梯间:建议采用定型全钢大模板;电梯井建议采用专用钢模板;e)基础及地下沟道:模板种类可适当放宽,若使用钢模板,必须使用优质普通钢模板。
