EPS模块保温系统施工技术交底

1.1、材料准备

EPS直板模块（60mm、90mm）、EPS直角模块、自由Ⅰ型连接桥、自由Ⅱ型连接桥、电焊网、拉结钢筋、企口防护条、钉子、C18钢筋、A6钢筋等

1.2、主要器具

泡沫电热刀、泡沫电熔丝、裁切模块等

1.3、技术准备

1.3.1施工前，各施工队主要负责人认真学习EPS模块保温一体化交底，并向施工人员进行交底；

1.3.2 保温板进场后对保温板质量、尺寸及完整性进行检查，对各类连接桥数量及型号进行核对，确认无误后吊装至施工楼层。

二、重难点分析

2.1、依据图纸要求，EPS模块保温系统外墙需首先浇筑保温板外侧50mm自密实混凝土，然后再于保温板内侧浇筑预拌混凝土，施工难度大，考验EPS模块保温系统拼装的严密性及对各种穿墙洞、模板穿墙螺杆的封堵。

2.2、EPS模块保温系统使用EPS模块进行拼装，后续还需要安装各类连接桥、电焊网、拉结钢筋、附加钢筋、企口保护条等配件，工艺复杂。如何在尽量短的时间内完成EPS模块的安装是本工程的重难点及主控点。

三、操作工艺

3.1、工艺流程

测量放线→EPS模块进场、吊运→拼装模块→安装连接桥→安装填充墙模块→安装电焊网→安装附加钢筋→安装穿墙套管→支设模板→浇筑混凝土→拆模

3.2、测量放线

依据蓝图弹出保温板外侧50mm厚保护层外边线，内侧弹出混凝土结构墙的内边线，外墙窗洞口处须弹出填充墙180mm保温板控制线、外侧50mm保护层外边线及内侧100mm保护层控制线。保温板安装及模板支设时，必须与弹好的边线对齐，以确保夹芯保温现浇体系的截面尺寸。

EPS模块及配套连接桥、电焊网等材料进场后，对其数量、尺寸及质量进行检查，确认无误后分类堆放至楼座周围指定区域，码放整齐，做好周围防火、防风、防雨及防护。楼层钢筋绑扎完毕，监理验收合格后使用塔吊吊运至使用楼层，须提前向塔司、信号工及其他操作人员进行安全交底。EPS模块及所需材料运至相应楼层后，将保温板及连接桥分类码放整齐。

3.4、拼装模块

拼装前，核对图纸，确认墙体模块厚度均为90厚。首先在楼板上放置墙体最下层阴阳角处保温板，注意区分上下防止倒置，相邻保温板通过两侧企口连接，拼接完毕后安装Ⅰ型连接桥，使用泡沫电熔丝及裁切模块裁切保温板，以保证墙体拼接完毕后严整、密实，裁切后的保温板不得随意丢弃，做到重复利用。

最下层拼接完毕后向上逐层拼接，注意相邻两层阴阳角处保温板须使用不同规格型号的角板，保证两层保温板上下错缝插接，以增强整体稳定性。最上层模块安装完毕后安装企口防护条。

EPS模块拼装时有以下几点注意事项

东西山墙处80mm厚模块与南北60mm模块拼接时，须使用泡沫电熔丝在80mm模块内立面一端开槽，开槽尺寸需使用钢卷尺度量精确，开槽时，将裁切模块放置在80mm模块

门窗洞口处保温板使用泡沫电熔刀进行切割，切割长度至下部模板控制线，切割时使用钢尺控制垂直度，保证顺直。

3.5、安装连接桥

EPS模块拼接完毕后，将连接桥插入到模块位置。自由Ⅰ型连接桥插入模块内侧、自由Ⅱ型连接桥插入模块外侧，连接桥安装至同一水平线上、上下对齐。需注意剪力墙处自由Ⅰ型连接桥长度同墙体（200mm、180mm），阳台处自由Ⅰ型连接桥长度为100mm。

填充墙模块分为140mm及160mm，施工时须对照蓝图进行区分。模块尺寸均按照蓝图尺寸下料，可直接进行安装。由于填充墙设置在窗洞口周围，需使用泡沫电热刀对填充墙进行切割以安装洞口抱框及压顶筋。切割尺寸为100mm×100mm，靠内侧切割，如下图所示。

填充墙模块安装完毕后外墙插入自由Ⅱ型连接桥，内侧插入100mm自由Ⅰ型连接桥。连接桥需同剪力墙EPS模块平齐，水平间距300mm，竖向间距300mm，上下对齐。

3.7、安装电焊网

电焊网安装至EPS模块外侧。将电焊网插入至连接桥十字插孔中，插入插销。转角及窗洞口处电焊网使用钢剪剪断，电焊网不得超出EPS模块外边缘。

3.8、安装附加钢筋

EPS模块剪力墙每平米须附加4个L型拉结钢筋，采用C8钢筋，短边长60mm，锚入混凝土墙体不小于80mm。

抱框柱及压顶梁处附加钢筋为2C10，箍筋为A6@200，使用铁丝绑扎连接。阳台处纵向附加钢筋为C8@200，横向附加钢筋为A6@200，使用铁丝绑扎连接。

3.9、安装穿墙套管

水电施工队根据施工图纸放置穿墙套管，主体施工队根据套管位置，使用泡沫电热刀对EPS模块进行切割。注意切割完毕后套管可以恰好穿过孔洞，不留缝隙。

3.10、支设模板

模板支设方法同墙体模板施工技术交底。需注意以下几点：

1）所有模板拼缝及转角处必须填压海绵条、粘贴密封胶带；

2）模板底部必须铺垫砂浆封堵严密；

3）穿墙螺杆或穿墙管开洞必须大小合适，若开洞过大必须进行进行处理或更换模板；

4）外墙模板必须在支设前必须对模板进行检查，重复利用的木模板在有破损或弯曲变形的情况下不得使用，严防涨模。

3.11、浇筑混凝土

根据EPS模块保温系统技术规程。需首先浇筑EPS模块外侧50mm厚保护层。使用自密实混凝土进行浇筑，浇筑时，在外侧模板上口设置漏斗及挡板，保证混凝土以较慢速度入模，不对保温板造成冲击挡板，防止浇筑到模板外。须设立两名以上看模人员，时刻注意外墙模板是否有漏浆，出现问题立即修复。自密实混凝土浇筑完毕后，使用普通预拌商砼浇筑模块内侧墙体及内墙。
