1、外墙变形缝处理

1. External wall deformation joint treatment

基层墙面结构变形缝主要包括伸缩缝、沉降缝，外保温系统应在变形缝处断开，岩棉板在此端口部位应该粘贴窄幅标准网布进行翻包。伸缩缝内设低密度聚乙烯泡沫塑料作为保温材料，表面打耐候硅酮封胶;沉降缝要根据缝宽和位置设置金属盖板，已射钉或螺丝紧固。

The deformation joints of the basic wall structure mainly include expansion joints and settlement joints. The external insulation system should be disconnected at the deformation joint, and the rock wool board should be pasted with narrow standard mesh fabric for flipping at this port. Low density polyethylene foam plastic is set inside the expansion joint as the thermal insulation material, and weather resistant silicone sealant is applied on the surface; The settlement joint should be equipped with a metal cover plate according to the width and position of the joint, which has been fastened with nails or screws.

2、女儿墙施工

2. Construction of parapet wall

女儿墙必须采取保温材料全包覆盖的做法，顶面以及侧面全部都使用防水性能较好的保温材料，女儿墙顶部应设技术盖板，而且需要向内做出一定的坡度，从而有利于散水。

The parapet wall must be fully covered with insulation materials, and both the top and sides should use insulation materials with good waterproof performance. The top of the parapet wall should be equipped with a technical cover plate, and a certain slope should be made inward to facilitate water dispersion.

3、门窗洞口

3. Door and window openings

门窗洞口在施工保温浆料之前，需要对于窗框和墙体连接部位用发泡聚氨酯或其他封闭物品进行填塞，同时在表面用水泥砂浆抹出小圆弧状。大面岩棉板粘贴时应在窗口部位端处采用窄幅网布翻包，翻包网布与大面网布进行搭接。窗侧边膨胀玻化微珠无机保温砂浆施工时，保温层厚度必须不小于20mm，从而防止出现局部产生热桥的情况。在施工门窗侧边保温层时需在下窗台做出一定坡度以利散水，窗口上沿应安装成品滴水线条，避免雨水污染墙面。窗洞口侧边与大墙面形成的阳角应采用护角条包角。

Before constructing insulation slurry for door and window openings, it is necessary to fill the connection between the window frame and the wall with foam polyurethane or other sealing materials, and at the same time, apply cement mortar to the surface to create a small circular arc. When pasting the large surface rock wool board, a narrow mesh should be used for flipping at the end of the window, and the flipping mesh should be overlapped with the large surface mesh. When constructing inorganic insulation mortar with expanded vitrified microbeads on the side of the window, the thickness of the insulation layer must not be less than 20mm to prevent the occurrence of local thermal bridges. When constructing the insulation layer on the side of doors and windows, a certain slope should be made on the lower window sill to facilitate water dispersion. Finished drip lines should be installed on the upper edge of the window to prevent rainwater from contaminating the wall. The corner formed by the side of the window opening and the large wall should be wrapped with corner protectors.

4、勒脚

4. Strangulation foot

当地下室没有保温要求时，散水坡以上不小于150mm部位设置金属托架，采用膨胀螺栓间距600mm将其固定在墙面上，金属托架以下即勒脚部位保温材料采用燃烧性能不低于B1级的高密度聚苯板，其高度为600mm,金属托架之上粘贴岩棉板。

When there is no insulation requirement for the basement, a metal bracket should be installed at a height of no less than 150mm above the apron slope, and it should be fixed to the wall with expansion bolts spaced 600mm apart. The insulation material below the metal bracket, i.e. the foot area, should be made of high-density polystyrene board with a combustion performance of no less than B1 grade, with a height of 600mm. Rock wool board should be pasted on top of the metal bracket.

当地下室有保温要求时，勒脚部位应该设置用镀锌锚栓固定于基层墙体的经防腐处理的金属托架，保温系统和室外散水间应预留不得小于20mm的间隙，填充条状保温材料，外口设置背衬，填充密封膏。

When there are insulation requirements for the basement, a corrosion-resistant metal bracket fixed to the base wall with galvanized anchor bolts should be installed at the foot of the building. A gap of no less than 20mm should be reserved between the insulation system and the outdoor water dispersion, filled with strip shaped insulation material, and a backing should be set at the outer opening, filled with sealing paste.
