1、http:/ http:/ of residence engineering exterior wall leakage causes and prevention and control 在住所工程施工中，外墙渗漏的表象时有发生。现依据咱们多年的施工实习，就住所工程外墙渗漏的成因和防治处置作一简略分析。In the residence construction, the appearance of the exterior wall leakage occur. Now based on our many years of construction practice, exterior wa
2、ll leakage causes and prevention and treatment of residence project is a brief analysis.一、 外墙渗漏的成因A, the cause of leakage of exterior wall导致住所工程外墙渗漏的缘由许多，由选材不妥、描绘失误、施工技术不规范，交付运用后点缀不妥等要素构成，详细有以下几种：1、外墙管道的预留孔密封处置不良；2、窗台板布局不合理，铝合金窗装置不规范；3、外墙面砖底层整理不完全，张贴砂浆不丰满，在墙体与面砖之间构成积水；4、外墙点缀龟裂；5、根底不均匀沉降构成墙体开裂；6、住所在二
3、次点缀期间，乱打滥建改动布局导致墙体开裂。Lead to external wall leakage causes many residence project, by selecting wrong, describe errors, the construction technology, delivery using the elements such as dot wrong after detailed has the following kinds: 1, the exterior pipeline of the reserved hole sealing disposal of
4、bad; 2, window sill board layout is unreasonable, aluminium alloy window unit is not standard; 3, exterior wall tile bottom finishing is not completely, mortar is not plump, posted on walls and brick between water; 4, exterior ornament cracking; 5, differential settlement of the foundation wall crac
5、king; 6, residence during the secondary ornament, disorderly make arbitrary construction layout changes result in the crack of the wall.二、 外墙渗漏的防治Second, exterior wall leakage prevention（一） 外墙管道和预留洞的渗漏防治(a) wall pipe and reserved hole leakage prevention and treatment外墙管道和预留洞渗漏的防治办法有三种：1、经过改善施工技术，尽量削
6、减外墙操作洞孔的留置。2、在铲除操作洞孔内的杂物后，用水泥砂浆及砖块对外墙洞孔进行仔细填塞，确保填塞密实。3、严厉执行查看准则，在对工程主体布局进行查看时，关于外墙填塞不规范、不密实的洞孔，有必要需求施工单位返工。Exterior wall leakage of pipeline and the reserved hole control way has three: 1, through improving the construction technology, try to reduce external operation holes under lien. 2, after the
7、remove operation hole hole stuff, with cement mortar and brick external wall hole hole to fill carefully, ensure the tamping compaction. 3, strict execution check criterion, when to see the main layout project, on the wall to fill the holes of non-standard and imperfect, it is necessary demand const
8、ruction unit rework.（二） 窗台和铝合金的渗漏防治 窗台渗漏是因为窗台描绘不妥所构成。对于板斜度较小、填充硅胶老化、掉落等缘由，可采纳以下办法：1、选用小圆弧嵌胶技术，将硅胶沿窗台小圆弧的顺直方向抹压，有些胶透过铝合金窗下框与小圆环处预留的缝隙挤满，以确保铝合金窗与洞口墙体的衔接为弹性衔接。2、选用窗台板一次成型技术，使窗台板制造一次成型。 铝合金窗的防渗漏办法主要是：1、把好资料关，尤其是要把住铝型资料和氧化膜的厚度关。2、把好制造关。铝型材的下料尺度的差错要严厉操控在答应误差范围内，使得成型后的铝合金窗到达节缝紧密、全体方正。3、把好施工关。严厉操控铝合金窗预留洞口尺度
9、，做到内外打胶到位、密实、顺直。4、把好检验关。在对铝合金窗工程进行检验时，采纳淋水试验的办法以查看其抗渗功能。(2) the windowsill and leakage of the seepage prevention of aluminum alloy window because the window paint not satisfactory. For plate Angle smaller, filled with silica gel aging, drops wait for a reason, can adopt the following measures: 1, ch
10、oose small arc embedded technology, wipe the straight direction of silica gel along the window small arc pressure, some glue through the lower frame of aluminium alloy window and small circle place reserved gap filling, to ensure that the aluminium alloy window for elastic cohesion with the mouth of
11、 the cave walls. 2, choose windowsill board a molding technology, make the windowsill board manufacturing a molding. Aluminium alloy window of seepage prevention measures mainly: 1, put the good information, especially to forbid the aluminum type material and the thickness of the oxide film. 2, make
12、 good clearance. Aluminium blanking dimension errors to strict control within the scope of the promised to error, forming of aluminium alloy window after arrival in sewing section closely, all the founder. 3, good construction. Harsh manipulation of the aluminium alloy window to reserve the hole dim
13、ension, to glue in place, both inside and outside close-grained, straight. 4, good the gate. When aluminium alloy window engineering test, water spray test method adopted to view its permeability functions.（三） 外墙面砖构成渗漏的防治(3) the wall brick of leakage prevention 防治外墙面砖构成的渗漏可选用如下办法：1、对进入现场的外墙面砖要严厉按规范抽
14、样进行复试，尤其要复试其抗冻功能。复试不合格的面砖应制止用于工程上。对面砖进行逐块选择，将有外观缺点的面砖（如开裂、缺角、掉楞等）剔除去。2、严厉依照面砖铺贴程序施工。当运用块材的面积较小时，可运用一底一中一面的办法（即一底为刮底糙，一中为抹中层灰，一面为批灰铺贴面砖）；当运用块材的面积较大时，可运用一底两中一面的办法。3、底层整理。打扫墙面，使砌体灰缝凹进墙面10mm,用1:3水泥砂浆修补空头缝，以添加与打底灰浆的结合力。4、在施工前一天，对前面要均匀浇水，铲除尘埃并使墙体吸收必定的水分，然后抹1：3水泥砂浆，厚度为57mm, 用木蟹压浆打平密实，用刮尺刮平。6、按修建工程质量检验鉴定规范的
15、需求对墙面进行查看，符合需求后方可张贴面砖。7、张贴面砖。先将面砖在清洗水内浸泡2h，然后取出晒干，运用时到达外干内湿的程度， 待中层灰到达必定强度后，可张贴面砖。张贴面砖所用的张贴资料，要断定资料合作比，即水泥：砂子为1：1，水泥：107胶：水为10:0.5:2.6；一起要操控运用时间，做到随拌随用，张贴时要注意砂浆丰满度，确保张贴结实，无空鼓。8、勾缝。铲除张贴在面砖缝内的残浆，浇水潮湿，然后用1:1水泥砂浆勾缝，勾缝要凹进面砖1mm,勾缝砂浆应填嵌密实，接搓处要平坦，不留空地和接搓缝。9、整理墙面。运用洁净棉纱揩擦洁净，不留尘垢。做到不冻、不早脱水，以防开裂。Prevention and
16、 control of leakage of external wall face brick structure can choose the following way: 1, to enter the field of external wall tile sample for retest is according to the specification, especially to retest its frost resistance function. Second interview unqualified brick should stop used in engineering. To put tile choice, will have a look the drawback of the brick (such as crackin
