Description

一种装配式预制夹心保温外墙板的排水防渗装置及方法 技术领域
本发明涉及建筑施工技术领域，特别涉及一种装配式预制夹心保温外墙板的排水防渗装置及方法。
背景技术
目前装配式建筑已经在全国范围内开始推广应用。相比于传统的现浇结构建筑方式，预制构件在工厂制造、现场进行拼装的产业化建造方式具有质高、施工难度低、工期短、节约工程材料、对环境友好等优点。
一些地区的高层建筑通常采用“三明治式”的预制混凝土夹心保温外墙板拼装形成建筑的外墙。夹心保温外墙板通常包含内、外叶墙板以及固定连接设置在内、外叶墙板之间的保温层。在夹心保温板外墙施工过程中，因外墙预留板缝多，在后续施工过程中一般需要进行填缝处理，现有处理方式虽能够填补缝隙，但存在大量的渗水隐患。主要弊端有：外墙一旦出现渗水点，渗入水在保温层无法排出，日积月累会在保温层内部形成间隙水水压，容易从混凝土拼接缝及水泥砂浆封堵的孔洞处渗入室内，造成室内装修被破坏需要重新返工，耗费时间与金钱。

高层建筑的外墙通常由“三明治式”的预制夹心保温外墙板10拼装而成。如图1所示，夹心保温外墙板10通常包含内、外叶墙板11以及固定连接设置在内、外叶墙板11之间的保温层12，所述内、外叶墙板11可以为混凝土材质，所述保温层12可以是挤塑聚苯材质。夹心保温外墙板10通常还预留有若干个安装外部构件的孔洞50，所述孔洞50为穿设内叶墙板13、 保温层12、外叶墙板11的通孔，孔洞50的第一端、第二端分别对应外叶墙板11、内叶墙板13。通常建筑物的相邻夹心保温外墙板10之间具有拼接缝40，该拼接缝40的宽度通常为10mm至30mm。但在吊装夹心保温外墙板10的过程中受外界因素影响、或操作不当时，拼接缝40的宽度甚至会达到40mm左右。通常需要填充拼接缝40，防止建筑物外墙进水。
在填充拼接缝40时，需要在拼接缝40内嵌入衬底，然后在衬底上注入密封胶30。这种方式虽然能够填充拼接缝40，然而当夹心保温外墙板10出现渗水点，渗入水无法排出，日积月累会在保温层12内部形成间隙水水压，容易从拼接缝40及水泥砂浆封堵的孔洞50处渗入室内，造成室内装修被破坏需要重新返工。
本发明提供一种装配式预制夹心保温外墙板的排水防渗装置，如图2、图3所示，包含：
柔性防水材质的多个软管20；沿所述软管20的长度方向，在软管20开有连通软管内、外部的多个排水孔21；所述软管20嵌入设置在所述拼接缝40内并位于相邻的外叶墙板11之间，所述排水孔21贴合外叶墙板11的侧面；外叶墙板11的渗水通过排水孔21流入软管内，通过所述多个软管20连接形成夹心保温外墙板10的排水通道。在本发明的实施例中，所述排水通道较低的一端可以连通固定设置在建筑外墙的排水管，排水通道内的水可以通过排水管排至下水道。在本发明的实施例中，软管20为聚乙烯材质。沿软管20的长度方向，相邻排水孔21的间距为10～50cm。
在本发明的一个实施例中，如图2、图3所示，在软管20相对的两侧均设有排水孔21。当拼接缝40的宽度不超过30mm时，通常在拼接缝内使用如图2、图3所示的软管20，软管20的直径匹配拼接缝宽度。如图4所示，软管两侧的排水孔21分别贴合拼接缝两侧外叶墙板11相对的侧面，软管两侧外叶墙板11的渗水均能够通过软管20对应一侧的排水孔21流入软管内。如图5所示，本发明的软管20不仅可以嵌入设置在竖直的拼接缝40内，也可以嵌入设置在水平的拼接缝40内，且水平的软管内部与竖直的软管内部互相连通。图5中，竖直方向的拼接缝40较长，在该拼接缝40内可以嵌入多个依序连接的软管20以形成一路排水通道，软管20之间还可以通过粘合剂粘连在一起。
如图6、图6A所示，在本实施例中，软管两端的端面切有一个斜角，该斜角优选为45度。通过软管20的斜角端面，增加相邻软管20的粘连面积。
在本发明的一个实施例中，如图7、图8所示，仅在软管20的一侧设有排水孔21。当拼接缝40的宽度超过30mm时，通常在拼接缝40内使用如图7、图8所示的软管20。软管20的直径匹配拼接缝40宽度的一半。如图9所示，一个软管20对应一侧的外叶墙板11，两个软管20的排水孔21分别贴合对应外叶墙板11的侧面，对应外叶墙板11的渗水均能够流入对应的软管内。图9中，拼接缝40之间具有两路排水通道。
本发明还提供一种装配式预制夹心保温外墙板的防水处理方法，采用如本发明所述的装配式预制外墙的排水防渗装置实现的，所述处理方法包含步骤：
S1、封堵夹心保温外墙板10的孔洞50；清理拼接缝两侧外叶墙板11外立面上的附着物；例如通过磨光机或铲刀等工具去除外叶墙板11上的灰尘、油漆、水泥浮浆等。
步骤S1中封堵夹心保温外墙板10的孔洞50包含步骤：
S11、将孔洞第一端凿成喇叭形(喇叭形的轴向长度不小于20mm)，所述喇叭形开口较大的一端(直径不小于40mm)落在外叶墙板11的外立面上，防止外部的水通过孔洞50流向室内。
S12、向孔洞内填充发泡剂51，如图10所示，所述发泡剂51与孔洞两端端面分别具有一个距离；在本实施例中，该距离优选为45～55mm。
S13、将掺杂有防水粉的膨胀水泥砂浆52分别从孔洞两端注入孔洞50内，实现封堵孔洞50，且膨胀水泥砂浆52与发泡剂51之间无空隙。
当拼接缝宽度小于设定的阈值，进入S2；当拼接缝宽度大于设定阈值，进入S3；在本实施例中，所述设定的阈值为30mm。
S2、采用如图2、图3所示的软管20(软管相对的两侧均设有排水孔21)，将软管20嵌入设置在相邻夹心保温外墙板10之间的拼接缝40内(如图4、图5所示)，软管20的长度方向为拼接缝40的长度方向，软管20的直径匹配拼接缝40的宽度，软管两侧的排水孔21分别贴合拼接缝两侧外叶墙板11相对的侧面；进入S4；
S3、采用如图7、图8所示的软管20(仅在软管20的一侧设有排水孔 21)；如图9所示，将两个软管20并列嵌入设置在拼接缝40内，软管20的长度方向为拼接缝40的长度方向，软管20的直径匹配拼接缝宽度的一半；两个软管20的排水孔21分别贴合对应外叶墙板11的侧面(此时在拼接缝40中具有两路排水通道)；进入S4；
S4、在软管20、相邻外叶墙板11包围形成的空间内，分多次注入密封胶30；压实、修整密封胶30，使密封胶30完全填充所述空间。
在本发明的实施例中，所采用的密封胶30为耐候胶，其具有较好的粘结性、耐候性、耐久性、可涂刷性和抗位移能力。
步骤S4中所述修整密封胶30包含：当施工时的环境温度高于设定的温度时，刮平密封胶表面，如图11A所示，使密封胶表面与外叶墙板11的外立面平齐；当施工时的环境温度低于设定的温度时，如图11B所示，将密封胶表面修饰成凹面。
本实施例中，注入密封胶30应遵循由下向上，由拼接缝边缘向拼接缝中间的原则，同时分两次注入密封胶30，待第一次注入的密封胶30完全固化后进行第二次注胶，避免因重力导致流挂，从而密封胶30塌陷。在一些优选的实施例中，若拼接缝40的宽度小于30mm时，密封胶30的宽厚比为1∶1至2∶1，且密封胶30厚度不小于10mm；当拼接缝40的宽度达到或超过30mm时，密封胶30的厚度应大于15mm。
在一些实施例当中，所述装配式预制夹心保温外墙板的防水处理方法还包含：如图12所示，注入密封胶30前，在拼接缝两侧的外叶墙板11外立面上贴美纹纸60；并在第二次注入的密封胶完全硬结之前，拆除美纹纸60。
在一些实施例中，还会对建筑物外墙进行淋水试验，通过加压水泵对外墙进行加压喷淋以检验外墙渗漏。基于所述淋水试验检验本发明软管20的排水防渗效果。
本发明的排水防渗装置不仅能够在填补建筑物相邻夹心保温外墙板10的拼接缝时，作为密封胶30的内衬；同时还能够用于夹心保温外墙板10的防渗漏处理，能够排出夹心保温外墙板10渗水，提高外墙防水能力，有效避免后期夹心保温外墙板10渗水造成室内装修返工。本发明的排水防渗装置结构简单、性价比高，大大的节约了建筑成本，具有很好的市场前景。本发明的装配式预制夹心保温外墙板10的防水处理方法可操作性强，操作过程 易于控制，符合绿色施工和建筑产业现代化的要求。
