墙体柱模板安装

一、施工准备

1.1 作业条件

1.1.1模板线和模板控制线测设并弹线完毕，水平控制标高50cm水平线引测到预留插筋上，并涂染成“▼”。

1.1.2模板表面清理干净。

1.1.3 墙体、柱跟部混凝土剔凿完成。

1.2 材料准备

15mm木质多层板、5×10木方、10×10木方、φ48钢管、扣件、螺旋模板锁。

1.3 主要机具

榔头、活动（套口）扳手、水平尺、钢卷尺、托线板、脚手板、锤子、铁钉。

二、操作工艺

2.1 墙体模板

2.1.1 模板设计

1、墙体采用15mm厚木质多层板做模板面板，5×10木方做模板次龙骨、φ48钢管做背楞, Φ14对拉螺栓做固定拉杆。

2、次龙骨设置：5×10木方沿模板高度每20cm设置一道。

3、主龙骨设置：主龙骨采用φ48钢管，沿模板长度方向设置9道，间距为：起步150mm，300 mm，300 mm，300 mm，450 mm，450 mm，450 mm，450 mm，450 mm。

4、对拉螺栓设置：墙体两侧模板施工时采用Φ14螺杆沿跨度方向为600mm。

2.1.2 工艺流程

预加工带次龙骨的模板→拼装模板 →安装钢管主龙骨背楞→安装穿墙螺栓→调整固定→加斜撑并调模板平直

2、当做分项工程施工技术交底时，应填写"分项工程名称"栏，其他技术交底可不填写。

2.1.3 操作工艺

1）墙模板安装时，根据边线先立一侧模板，依次立其它面模板，临时用支撑撑住，用线锤校正模板的垂直，然后固定背楞，再用斜撑固定。

2）为了保证墙体的厚度正确，在两侧模板之间用“工”字顶模棍（长度等于墙厚）。为了防止浇筑混凝土的墙身鼓胀，必须按要求控制好对拉螺栓的间距。

2.2柱模板

1、采用15mm厚木质多层板做模板面板，5×10木方做模板次龙骨、φ48钢管做背楞，螺旋模板锁做固定拉杆。

2、次龙骨设置：沿柱截面设4道背楞

3、主龙骨设置：主龙骨采用φ48钢管，沿模板长度方向每600设置一道，每道主龙骨采用两根Φ48钢管。

4、对拉螺栓设置：沿主龙骨位置设置，第一道距底边150mm，柱高中线以下300mm一道，柱高中线以上450mm一道。

5、利用底板预留地锚和斜撑钢管形成支撑体系，钢管斜撑分上中下三道，浇筑时要把地锚预埋好，保证钢管斜撑与地面的夹角不超过60度。

2、当做分项工程施工技术交底时，应填写"分项工程名称"栏，其他技术交底可不填写。

 2.2.2 工艺流程

预加工带次龙骨的模板→拼装模板 →安装钢管主龙骨背楞→安装螺旋模板锁→调整固定→加斜撑并调模板平直。

2.3模板的拆除及清理 

2.3.1模板拆除时，混凝土强度应以能保证其表面及棱角不因拆模而受损坏，预埋件或外露钢筋插铁不因拆模碰扰而松动。

2.3.2先拆除支撑，自上而下拆掉对拉螺栓。

2.3.3拆下的模板要及时清理掉砼等杂物，然后按场地分类码放，并涂刷脱模剂。下次使用模板前，必须经相关工长验收后方可用于工程上。

3.2.1 模板安装应满足下列要求：

1、模板的接缝不应漏浆；

2、模板与混凝土的接触面应清理干净。

3、浇筑混凝土前，模板内的杂物应清理干净；

3.2.2 固定在模板上的预埋件、预留孔和预留洞均不得遗漏，且应安装牢固，其偏差应符合下表的规定。

3.3注意事项：

3.3.1轴线位移：根部和顶部无固定措施。要求距地面5－8cm处焊顶模杆。支模前要有50cm水平控制线，并按控制线砂浆找平，模板上部伸出钢筋上要有上层50cm水平控制线标志。

3.3.2接缝不严：主要在模板与地面、模板与模板交接处。

3.3.3模板不垂直：支点位置不当，上下支撑不在同一轴线上、螺栓螺母紧固程度不一致。

3.3.4拆模混凝土受损：拆模过早，破坏砼楞角，要求按申请、批准拆模程序进行。
