铝合金框与墙体的配合处渗漏水的原因
Reasons for leakage of aluminum alloy frame and wall
1、在安装铁脚时，在门窗的下口不建议采用紧固螺丝来来实现铁脚与铝合金框的连接，如下口采用螺丝，则在螺丝与铝框的配合处有一个漏水隐患；
1. When installing iron foot, it is not recommended to use fastening screws at the bottom of doors and windows to realize the connection between iron foot and aluminium alloy frame.
处理方案：采用卡接式铁脚。
Processing plan: adopt clip iron feet.
2、铝合金框与洞口之间的安装间隙偏小或偏大，偏小时填充材料无法填充到位，偏大时填充材料无法填实，都会造成渗漏水；
2. The installation gap between the aluminum alloy frame and the hole is too small or too large, the filling material can not be filled in place when it is too small, and the filling material can not be filled when it is too large, which will cause leakage.
处理方案：首先在核测洞口尺寸时应充分考虑四周边的预留间隙，对于后置安装，一般建议单边预留7~10m的配合间隙，其次，在现场安装时，上、下、左、右的间隙基本调节均匀，杜绝出现一边大一边小的情况。
Processing plan: Firstly, the pre-reserved clearance around the hole should be fully taken into account when measuring the hole size. For post-installation, unilateral reserved 7-10m clearance is generally recommended. Secondly, in the field installation, the upper, lower, left and right clearances are basically adjusted evenly to prevent the occurrence of one side large and one side small.
3、、填充材料的选择。目前使用在铝合金框与洞口之间的填充材料主要为防水沙浆与聚氨脂发泡剂，防水沙浆标号的选择不合理，会造成达不到预期的防水效果；不合格的聚氨脂发泡剂的选用（如膨胀后的密度、膨胀时间、防水等性能不达标），也会造成渗漏水现象；
3. Filling material selection. At present, the filling materials used between aluminum alloy frame and cavity are mainly waterproof mortar and polyurethane foaming agent. The unreasonable selection of waterproof mortar label will result in the unsatisfactory waterproof effect; the selection of unqualified polyurethane foaming agent (such as the density after expansion, expansion time, waterproof and other properties are not up to standard), and so on. It will cause leakage.
处理方案：选择合适的防水沙浆及发泡剂；
Treatment plan: choose suitable waterproof mortar and foaming agent.
4、临时定位及承重垫块在门窗安装完成后有无折除并补填填充材料。门窗现场安装时用的垫块是临时使用的，在窗安装完成并填充材料已使用后，应折除此垫块，并在折除部位补填填充材料，否则会造成渗漏水；
4, temporary positioning and bearing pad in the doors and windows after installation, whether there is no folding and filling materials. The pad used in the field installation of doors and windows is temporary. After the window is installed and the filling material has been used, the pad should be broken down and filled with filling material in the folding position, otherwise it will cause leakage.
处理方案：折除临时定位块并补填填充材料；
Treatment plan: dismantle temporary location blocks and fill up filling materials.
5、室外侧铝合金框与墙体配合处的密封处理。室外侧的密封材料，一般选用硅酮密封胶，密封胶的选择及打胶的厚度等，都将直接影响水密性，差的胶一是相容性与粘接性不好，同时在胶干燥后易开裂，如胶打得薄也会开裂，后会造成成渗漏水；
5. The sealing treatment of the aluminum alloy frame and the wall at the outdoor side. Outdoor sealing materials, generally choose silicone sealant, sealant selection and thickness of glue, will directly affect the water tightness, poor glue one is compatibility and adhesion is not good, while the glue is easy to crack after drying, such as thin glue will crack, will cause leakage;
处理方案：选择合适的密封胶，同时在打胶进时建议胶中间的厚度不小于6mm;
Treatment plan: choose the appropriate sealant, and at the same time, the thickness of the adhesive should not be less than 6mm.
