1、轻骨料混凝土现场拌制工艺标准（419-1996）范围 本工艺标准规定了轻骨料混凝土现场拌制的施工准备、操作工艺、质量标准和质量验收资料等。本工艺标准适用于工业与民用建筑的轻骨料混凝土的现场拌制。施工准备 2.1材料及主要机具：2.1.1水泥：水泥的品种、标号、厂别及牌号应符合混凝土配合比通知单的要求。水泥应有出厂合格证及进场试验报色。2.1.2砂：砂的粒径及产地应符合混凝土配合比通知单的要求。砂中含泥量；当混凝上强度等级C30时，其含泥量应3%；混凝土强度等级C30时，其含泥量应5%。砂中泥块的含量（大于5mm的纯泥）：当混凝土强度等级C30时，应1%；混凝土强度等级0。若必须小于-50mm，
2、应按设计要求加大甩筋长度。搁置长度的状态见图4-40。3.5.3在砖混结构中，板伸入支座的长度一般宜大于50mm。3.6按设计规定，整理叠合板四周甩出的钢筋，不得弯90，亦不得将其压于板下。质量标准 4.1保证项目：4.1.1构件吊运时混凝土强度必须符合设计要求和施工规范的规定。检查方法：检查构件出厂证明和同条件养护试块的试验报告。4.1.2叠合板接缝处的混凝土必须计量准确，浇捣密实，养护充分，其强度必须达到设计要求或施工规范的规定。检查方法：观察和检查标准养护龄期28d试块抗压试验报告及施工记录。4.1.3叠合板的型号、位置、支点锚固必须符合设计要求，已无变形损坏现象。检查方法：观察或尺量检
3、查和检查吊装记录。4.2基本项目：叠合板的标高、坐浆、板缝宽度，应符合设计要求和施工规范的规定。检查方法：观察、足量检查。4.3允许偏差项目，见表4-37。表4-37项次 项目 允许偏差(mm) 检查方法 1 轴线位置位移 5 尺量检查 2 层高 10 用水准仪或尺量检查 3 板搁置长度 10 尺量检查 抹灰5 不抹灰3 成品保护 5.1叠合板的堆放及堆放场地的要求应严格按2.2.4条执行。5.2现浇墙、梁安装叠合板时，其混凝土强度要达到4MPa时方准施工。5.3叠合板上的甩筋（锚固筋）在堆放、运输、吊装过程中要妥为保护，不得反复弯曲和折断。5.4吊装叠合板，不得采用“兜底”、多块吊运。应按预
4、留吊环位置，采用八个点同步单块起吊的方式。吊运中不得冲撞叠合板。5.5硬架支模支架系统板的临时支撑应在吊装就位前完成。每块板沿长向在板宽取中加设通长木楞作为临时支撑。所有支柱均应在下端铺垫通长脚手板，且脚手板下为基土时，要整平、夯实。5.6不得在板上任意凿洞，板上如需要打洞，应用机械钻孔，并按设计和图集要求做相应的加固处理。质量记录 本工艺标准应具备如下质量记录：6.1混凝土构件出厂合格证。6.2结构吊装记录。6.3预制构件吊装工程预检。6.4分项工程技术交底。6.5分项工程质量检验评定。Opinions and suggestions on the partys mass line educ
