1、高层建筑施工中容易出现质量问题浅谈 摘要:随着我国社会经济的快速发展,高层建筑在城乡建设中越来越多,这些高层建筑的建设,充分得发挥了土地的综合利用率,有效的缓解了土地紧张的问题。但在高层建筑施工过程中,有很多部位容易出现质量问题部位。这些问题的存在,不但影响施工进度,影响工程质量,也会给用户带来很多不便。在此提出,希望能与大家探讨,共同推动建筑施工技术进步。在高层建筑钢筋分项工程中,容易出现不同级别钢筋混用,钢筋翻样错误,交叉作业及混凝土浇筑过程对成品钢筋的破坏等问题。混凝土分项工程中常出现结构混凝出现裂缝,如阳台、楼面、梁端等部位;
2、竖向及水平施工缝剔凿、清理不到位等造成施工缝接茬处质量较差;混凝土结构外观质量出现较大偏差等。在门窗工程中常常会出现门窗固定不牢固,门窗与墙体之间的缝隙处理不当引起渗水,门窗型材受损,门窗扇开启不灵活等质量问题。外墙外保温施工过程中常出现螺栓眼封堵不密实,墙体基层过于干燥,墙体有附着物、凸物等造成保温体系粘接不牢固,保温板空鼓和虚贴,锚固点不牢固,门窗口灯洞口部位收口不规范,冬季施工中砂浆、涂料等受冻灯问题。关键词:高层建筑质量问题钢筋混凝土门窗Abstract:withtherapiddevelopmentofour13sociale
