模板的安装注意事项 模板的安装注意事项提要:模板的拆除须注意不得硬撬硬砸,以免损伤混凝土结构,拆下的模板应进行清理修整,并涂刷脱模剂。装拆模板轻拿轻放,防止模板变形 模板的安装注意事项 1、安装注意事项 (1)竖向模板和支架的支承部分,当安装在基土上时应夯实并加设垫板,并且基土设有排水措施。 (2)模板及其支架在安装过程中,必须设置防倾覆的临时固定设施,并多次对成形模板的垂直度及平整度进行检查与校正,保证其误差在规范允许范围之内。 (3)当梁板的跨度大于4m时,模板应起拱,起拱高度为全跨长度的1/1000~3/1000。 (4)模板的支撑必须稳固,确保几何形状,模板拼缝须严密,保证混凝土浇捣不漏浆。 (5)施工过程应多次检查轴线位置,几何尺寸、标高等,施工完毕后须全面复核。 (6)模板施工时须注意预埋件和预留孔,不得遗漏,且安装要牢固,位置准确。 (7)模板的拆除须注意不得硬撬硬砸,以免损伤混凝土结构,拆下的模板应进行清理修整,并涂刷脱模剂。装拆模板轻拿轻放,防止模板变形。 (8)当构件跨度不大于4m时,在混凝土强度符合设计的混凝土强度标准值的50%的要求后,方可拆除;当构件跨度大于4m时,在混凝土强度符合设计的混凝土强度标准值的75%的要求后,方可拆除。 (9)已拆除模板及其支架的结构,在混凝土强度符合设计混凝土强度等级的要求后,方可承受全部使用荷载;当施工荷载所产生的效应比使用荷载的效应更为不利时,必须经过核算,加设临时支撑。 2、模板及其支架的设计应考虑下列各项荷载: (1)模板及其支架自重; (2)新浇注混凝土自重; (3)钢筋自重; (4)施工人员及施工设备荷载; (5)振捣混凝土时产生的荷载; (6)新浇注混凝土对模板侧面的压力; (7)倾倒混凝土时产生的荷载。 Measures for the routine management of moral education in Middle SchoolsMethod of conventional management of moral education in middle schoolFirst, the guiding ideology:School moral education is an organic whole of the whole education work, always adhere to the school adhere to the moral education, education for this product, and actively promote the quality education, the school building efficient curriculum system of moral education, moral education, improve the sense of attraction and appeal, enhance the moral education work for through and timeliness.
