一．工程概况

本工程为西安市燃料总公司阿房路住宅楼，地下一层，地上二十

六层，全剪力墙结构。地下室层高为5100㎜，一层层高为为4990mm，

二层层高为3600米、三层层高为3300米，±0.000以上标准层层高

为2900㎜，结构楼板厚度最低为110㎜，主体墙厚200㎜。

二．编制依据

1、依据提供的图纸及变更文件。

2、工程遵循的标准：

（1）《工业民用建筑结构荷载规范》

（2）《钢筋混凝土结构设计规范》

（3）《钢结构设计规范》

（4）《建筑设计手册》

（5）《钢筋混凝土工程施工及验收规范》

（6）《建筑工程大模板技术规范》

三．施工部署

为保证剪力墙砼工程质量，达到清水砼标准，本工程标准层（3～

26层）墙体砼模板采用钢质大模板，以9～11轴为界，分为两个施工

段，交叉流水施工。

四．模板结构

1.模板结构设计

（1）模板设计参数：设计侧压力F=60KN/㎡。

（2）模板组件材料选用：

1

a、面板选用t=6㎜厚钢板，材质Q235—A。

b、左、右、下边框选用8#角钢，上边框选用8㎜钢板，材质Q235

—A。

c、竖肋选用8#槽钢，材质Q235—A。

d、横龙骨选用双10#槽钢，材质Q235—A。

2、模板的结构（单位为mm）：

（1）竖肋布置：竖肋布置是先以两端225，然后再从两端往中间以间

距n×300布置，余数尺寸留在中间（中间余数净尺寸不得超过300）。

（2）、横龙骨布置：横龙骨用成对的10#槽钢背对背布置四道在竖肋

上，两槽钢之间留有对拉螺栓孔位置，其尺寸等于55㎜。横龙骨两

端开有20×40长孔，其用途是为了安装模板连接板，以此加强模板

刚度和控制模板拼缝间的错台量。竖向间距从下往上布置，间距为

300、650、750、900、300。

（3）边框布置：上、下边框连接孔为（150，30
