1、植筋工程的方案编制、施工作业、检测验收均以《混凝土结构加固技术规范》CECS25︰90为标准。
2、植筋规格、数量、钻孔深度如下:
植筋规格(mm)φ8φ18φ22φ25
植筋数量(根) 366 116 48 106
钻孔深度(mm) 120 270 330 375
3、挑梁上部钢筋胶粘剂采用喜利得结构胶,其他部位钢筋胶粘剂采用国产A级胶。钢筋植入后7日内严禁受到触动和干扰,并按结构胶说明书要求加强保养和围护。
4、钢筋植入固化10日后,委托具备相应资质的检测单位,在监理见证下随机抽样进行现场抗拔抽检,每种规格钢筋现场抗拔数量不得少于壹组,经检测合格后,才能进行钢筋连接和安装绑扎等后序工作。
5、现场检测抗拔力,当钢筋为Ⅲ级螺纹钢时抗拔力要求必须≥360MPa;当钢筋为Ⅱ级螺纹钢时抗拔力要求必须≥300MPa;当钢筋为Ⅰ级钢时抗拔力要求必须≥210MPa。
主要是建筑物加固采用植筋的方式,例如龙骨缺陷等建筑主体部位。
