1、 Preparation for window installation

窗户安装前，需要对窗户产品进行检查、看安装环境是否合适、是否需要拆下旧窗户等，诸如此类的事项都要在窗户安装前搞定。

Before installing windows, first check the window products to see whether the installation environment is appropriate and whether the old windows need to be removed. Such matters should be completed before installing windows.

1、检查窗户产品是否合格

1. Check whether the window products are qualified

窗户进场时必须经过检查验收。一是外观检查，查其有无破损、断裂;二是尺寸验收，查框的四边尺寸，查扇的方正、翘曲，做到安装前的质量预控。

Windows must be inspected and accepted when entering the site. First, conduct appearance inspection to check whether it is damaged or broken; The second is the dimension acceptance. Check the dimensions of the four sides of the frame, check the squareness and warpage of the fan, and achieve the quality pre control before installation.

其次是检查紧固件、五金件、增强型材及金属衬板等，看表面是否进行了防腐处理。如果采用的是固定片固定，固定片厚度应大于或等于1.5mm，小宽度应大于或等于15mm，其表面应进行镀锌处理。

Secondly, check fasteners, hardware, reinforced profiles and metal lining plates to see whether the surface has been treated with anti-corrosion treatment. If the fixing piece is used for fixing, the thickness of the fixing piece shall be greater than or equal to 1.5mm, the minimum width shall be greater than or equal to 15mm, and its surface shall be galvanized.

2、窗户洞口检查

2. Window opening inspection

想要窗户有良好的密闭性与稳固性，安装时注意平整度是关键。而保持平整度，关键是处理好窗户洞口。装窗户前，需复核洞口尺寸是否正确、是否做了横平竖直，对不符合要求的洞口进行提前处理。

If you want windows to have good tightness and stability, pay attention to flatness during installation is the key. The key to maintaining flatness is to deal with the window opening. Before installing windows, it is necessary to check whether the hole size is correct and whether it is horizontal and vertical, and deal with the holes that do not meet the requirements in advance.

3、旧窗户拆除方法

3. Old window removal method

不少业主家是用新窗户更换旧窗户，因此需要将旧窗户取下来。窗户拆除需要十分小心，防止拆除时对窗户周边装修和墙体造成破坏。一般来讲，木窗比较容易取下，塑钢窗和铝窗等则较复杂。

Many owners replace old windows with new ones, so they need to take down the old windows first. The removal of windows requires great care to prevent damage to the decoration around windows and walls. Generally speaking, wooden windows are easier to remove, while plastic steel windows and aluminum windows are more complex.

需要用刀片把窗户内侧的密封胶等切开，然后取窗框。窗户如果是采用膨胀螺栓与墙体连接的，可直接用螺丝刀把膨胀螺栓取下，如果胀栓生锈，则可用冲击钻将其打碎;而如果是采用连接片连接的则直接使用冲击钻即可，如果窗框难以取下，则需用钢锯将靠墙的框中部锯开取下。

First, cut the sealant inside the window with a blade, and then take out the window frame. If the window is connected to the wall with expansion bolts, the expansion bolts can be removed directly with a screwdriver. If the expansion bolts are rusty, they can be broken with an impact drill; If it is connected by connecting pieces, the impact drill can be used directly. If the window frame is difficult to remove, the middle of the frame close to the wall needs to be sawed off with a hacksaw.

二、窗户安装步骤

2、 Window installation steps

窗户一般由商家提供安装服务，而由于商家提供的服务质量参差不齐，且有些工人的操作并不规范，在一些关键节点，业主需要盯紧，避免出现疏忽影响窗户在使用过程中的质量。

Windows are generally installed by businesses. Due to the uneven service quality provided by businesses and the non-standard operation of some workers, the owners need to keep an eye on some key nodes to avoid negligence affecting the quality of windows in the process of use.

1、测尺寸

1. Dimension measurement

在使用铝合金窗时，封阳台前应准确地测量阳台封闭面的尺寸，在施工现场外按尺寸加工制作窗户框、玻璃，运抵施工现场。在安装前，应检验窗户尺寸与封阳台的洞口尺寸是否一致。

When using aluminum alloy windows, the size of the balcony sealing surface shall be accurately measured before the sun sealing platform, and the window frame and glass shall be processed and manufactured outside the construction site according to the size and transported to the construction site. Before installation, check whether the window size is consistent with the opening size of the balcony.

2、固定支架

2. Fixed support

方法1：用固定片固定

Method 1: fix with fixing piece

窗户安装前应先清理阳台洞口的基层，要求将窗户紧靠墙体的基层材料，并在固定点打孔，预设膨胀螺栓或塑料胀销，以便固定窗体。安装窗户时，应将窗户稳坐在洞口处，固定其位置，用螺丝加塑料胀销固定。

Before installing the window, the base course of the balcony opening shall be cleaned first. It is required to remove the base course material of the window close to the wall, punch holes at the fixed points, and preset expansion bolts or plastic expansion pins to fix the window. When installing the window, first sit the window firmly at the hole, fix its position, and fix it with screws and plastic expansion pins.

方法2：用膨胀螺栓固定

Method 2: fix with expansion bolt

一般情况，螺栓需10公分长。倘若遇到一些洞口打偏了，通过抹水泥等抹平。螺栓则需要12公分长，以便直接固定到原墙体的水泥浇筑层中，才能让窗框稳固。可以用手敲一敲，如果发现窗框周边的墙是空心的，则需要往深了打。

Generally, the bolt should be 10 cm long. If some holes are deviated, they shall be leveled by plastering cement, etc. The bolt needs to be 12 cm long to be directly fixed into the cement pouring layer of the original wall in order to stabilize the window frame. You can knock it by hand. If you find that the wall around the window frame is hollow, you need to go deep.

3、检查是否安正

3. Check for alignment

窗框与窗户洞口连接好后，应该检查窗户是否安装正了。若窗户安装不正，使用一段时间后可能会出现窗户越来越歪的情况。如果是常规的矩形窗户，可以直接量窗户的对角线(左下角和右上角、左上角和右下角)，两根线长度需一致;如果是圆弧型窗户，需要使用水平尺，尺上的气泡在中间表明窗户是正的;如果是倾斜的窗户，则需要使用吊锤。

After the window frame is connected with the window opening, check whether the window is installed correctly. If the windows are not installed correctly, the windows may become more and more crooked after being used for a period of time. If it is a conventional rectangular window, you can directly measure the diagonal of the window (lower left corner and upper right corner, upper left corner and lower right corner), and the length of the two lines shall be the same; If it is an arc-shaped window, a level ruler needs to be used, and the bubble on the ruler in the middle indicates that the window is positive; In the case of inclined windows, a hanging hammer is required.

4、打发泡胶

4. Bubble gum

窗户调整完后，就需要打发泡胶，填充窗框与墙之间的缝隙。待发泡胶固化后(一般需要2-3小时，冬天需要的时间更长)，将多余的发泡胶切割掉。

After the window is adjusted, you need to send foam glue to fill the gap between the window frame and the wall. After the foam adhesive is cured (it usually takes 2-3 hours, and it takes longer in winter), cut off the excess foam adhesive.

5、安装窗扇及其他配件

5. Installation of window sashes and other accessories

固定好窗框后，接下来就安装窗扇和其他配件了，注意安装要小心。

After fixing the window frame, install the window sash and other accessories. Pay attention to the installation carefully.

6、打密封胶

6. Apply sealant

打完发泡胶后，再在窗框的周边均匀抹上密封胶，以防止雨水从窗和墙体的安装缝隙渗入室内。

After styrofoam is applied, apply sealant evenly around the window frame to prevent rainwater from penetrating into the room from the installation gap between the window and the wall.
