Doors and windows are an important part of the home space. In addition to ventilation, doors and windows can also have unexpected decorative effects, making the entire house completely different in style. But you know what? During the decoration process, the installation quality of doors and windows will directly affect the safety and comfort of future home life. Now, let us take a look at the professional construction methods and installation standards of for doors and windows of the system!
▷Measurement of door and window openings
The measurement of door and window opening dimensions provides basic data for the design and production of doors and windows, which is ultimately related to the installation effect and quality assurance of doors and windows. According to the type of opening, the measurement of door and window openings can be divided into ordinary opening measurement and special-shaped opening measurement.
1. Measurement of ordinary openings
The size of door and window openings is mainly to measure the height and width of the door opening and the entry and exit positions of the left and right doors and windows. Due to reasons such as uneven walls or uneven walls, actual measurements often result in the phenomenon of "different measurement results due to different points." Therefore, everyone should pay attention to multi-point measurement when measuring, and measure accurate data based on the actual situation.
The actual operation should be based on the horizontal and vertical installation of the doors and windows in the opening. Since there are horizontal and vertical deviations in the opening during construction, it is necessary to use tape measure, hanging hammer and other tools to find the minimum horizontal width and minimum vertical height of the opening; record at least 3 measurement points, and take the minimum value. Irregular or serious hole openings need to be trimmed, and then measured again after the hole trimming is completed.
(wrong measurement method)
The measurement point at the hole should be selected as flat as possible. Obvious convex or concave points will seriously affect the measurement results.
2. Measurement of corner windows
When measuring the corner window opening, the height measurement is basically the same as that of the regular opening, but there is a clear difference when measuring the outer edge width (W1\W2) and the inner edge width (W3\W4). Generally speaking, the measurement width is based on the outer edge size: when measuring from the front, measure the distance from the outer corner of the balcony top to the outer wall, and record it as W1; when measuring from the side, also measure the distance from the outer corner of the balcony top to the outer wall The distance between the two sides is recorded as W2; after measuring the width of W1 and W2, the thickness of the window sill or wall must also be measured. Because the thickness of the wall, the selection of the product series, and the exact product installation location will all affect the width of the finished product.
3. Measurement of curved window
As shown in the figure, first measure the chord length and arc height, and then divide the chord length into several parts. Mark the corresponding points 1, 2, and 3 on AB. First measure the dimensions of A1, A2, and A3, and then measure the dimensions of C1, D2, and E3 (make sure that C1, D2, and E3 are perpendicular to AB during the measurement process) . After recording several sets of measurement data, trace the drawing on the computer or drawing paper. According to the measured points C, D, and E, use a smooth curve to draw the size of the arc-shaped hole. The more equal parts the chord length is divided into, the larger the size of the hole drawn. The more accurate it is (in addition to the above method, you can also use a paper sleeve to draw a line on the hole, draw the outline of the hole, and then measure the corresponding size from the paper sleeve).
▷ Wall installation of doors and windows
The wall installation of doors and windows is an important part of the installation of finished products. It plays a very critical role in the use of doors and windows and future maintenance, so it needs to be operated by professionals with rich installation experience. The installation of doors and windows can be divided into dry installation and wet installation according to different project requirements.
1. Dry installation (steel sub-frame installation)
a. Pre-embed the steel sub-frame in the rough hole. After the steel sub-frame is leveled on the wall, fill the gap between the attached frame and the hole with waterproof mortar , and fill the gap between the sub-frame and the hole. A gap of more than 10mm should be reserved. After fixing the sub-frame, apply waterproof coating ;
b between the outdoor side sub-frame and the opening. After the steel sub-frame is installed on the wall, indoor and outdoor decoration can be carried out. The finished surface is painted with steel The surface of the sub-frame shall prevail;
c. After the indoor and outdoor decoration is completed, the door and window frames must be put on the wall. Before the window frames are put on the wall, protective treatment must be done to prevent the doors and windows from being contaminated or scratched. The gap between the door and window frames and the steel sub-frame must be more than 5mm. Before the door and window frames are fixedly connected to the steel sub-frame, they must be leveled with a spirit level. The level of the window frame can be adjusted through the frame adjustment piece. After the level is leveled, it can be directly connected and fixed with the steel sub-frame;
d. After the door and window frames are fixed, The gap between the window frame and the steel sub-frame needs to be filled. Polyurethane foaming agent is usually used to fill the gap, and then weather-resistant sealant is applied to both the indoor and outdoor sides of the window frame to complete the sealing process. In this way, the wall installation of doors and windows is basically completed.
2. Wet installation (fixed piece installation)
The biggest difference between wet installation and dry installation: In wet installation, the window frame must be put on the wall before the wet work on the wall, while dry installation can be done after the indoor and outdoor decoration is completed. On the wall.
a. Insert the window frame into the rough opening. Do not tear off the protective film on the doors and windows before and after the window frame is inserted into the opening. This can avoid damage to the doors and windows during later construction; use wooden pads to adjust the gap between the window and the wall. After fixing the gap, fix the window frame;
b. After fixing the window frame, waterproofing treatment is required: fill waterproof mortar between the window frame and the wall. After filling with mortar to stabilize the window frame, remove the wooden pads. Then apply waterproof coating between the exterior window frame and the wall;
c. After the waterproofing treatment, you can do indoor and outdoor decoration. Before doing indoor and outdoor decoration, you must protect the doors and windows to prevent pollution and scratches. This step is especially important during wet installation.
