1、技术交底记录鲁JJ-005工程名称施工单位交底部位高层砌体工序名称砌体工程交底提要:砌体技术交底一、施工工艺1.工艺流程:墙体放线→搅拌砂浆→砌块排列→铺砂浆→砌块就位→校正→砌筑镶砖→竖缝灌砂浆→勒缝。 2.墙体放线:砌体施工前,将基础面或楼层结构面按标高找平,依据砌筑图放出第一皮砌块的轴线、砌体边线和洞口线。3.制配砂浆:按设计要求的砂浆品种、强度制配砂浆,配合比由试验室确定,采用重量比,机械搅拌,搅拌时间不少于2min。预拌砂浆加水至粘稠可使用。4.砌块排列:按砌块排列图在墙体线范围内分块定尺、划线。排
2、列砌块的方法和要求如下:4.1.砌块砌体在砌筑前,根据工程设计施工图,结合砌块的品种、规格、绘制砌体砌块的排列图,经审核无误,按图排列砌块;4.2.砌块排列(所有外墙除外)从梁底5cm向下排列,排列时尽可能采用主规格的砌块,砌体中主规格砌块占总量的75%~80%。窗台压顶位置若加气块无法排列可用粉煤灰砖砌筑。若粉煤灰砖无法满足则可适当将压顶厚度在±4cm内进行增减。4.3.砌块排列上、下皮错缝搭砌,搭砌长度一般为砌块的1/2,不得小于搭砌砌块长度的1/3,也不小于150mm。4.4.外墙转角及纵横墙交接处,将砌块分皮咬槎,交错搭砌。项
