6、：主楼：铸造车间，跨度21M，柱距6M，主体结构：预制钢筋混凝土装配式排架结构，巨星牛腿柱6t，柱埋入混凝土杯形基础0.6M。其它：T型预应力吊车梁，重1.4t预应力18t折行屋架，重6t。现浇混凝土上人平屋面，坡度2%，Ⅱ级防水，采用混凝土结构自防水与SBS高聚物改性沥青防水卷材3mm+3mm设防，100厚聚苯板保温材料，陶粒混凝土最薄处30mm找坡。二次结构：加气混凝土小型砌块装饰：简单装修（水泥砂浆底面、耐水腻子四白落地）水利水电出版社二、总括施工工艺本方案包括:地下工程，预制工程，结构安装工程，维护及装饰。施工顺序：（一）基础

7、工程施工顺序：基础工程施工的施工顺序为：基坑挖土——钎探验槽———做垫层——绑扎钢筋——安装模板——浇筑混凝土——养护——回填土等。在确定施工顺序是，厂房柱基础与设备基础的施工顺序它影响到主体结构和设备安装的方法与时间。（二）预制工程的施工顺序，单层工业构件的预制。工厂预制与工地预制相结合的方法进行，一般重大，较大或运输不便的可现场预制。本工程选择先张法预应力混凝土工程。顺序为：支座准备——刷隔离剂——铺放预应力钢筋——张拉——按侧模支横向筋——浇筑混凝土——养护——放张拉预应力筋——脱模——出槽——堆放预制构件的混凝土轴心抗拉强度应

8、达到设计值的75%以上才可以起吊。（三）结构安装的施工的顺序：安装柱子、连系梁、吊车梁、屋架、天窗架、屋面板等。每个构件的安装工艺顺序为：绑扎——起吊——就位——临时固定——校正——最后固定。第17页结构构件吊装前要做好
