Doors and windows are an important part of home space. In addition to ventilation, doors and windows can also play an unexpected decorative effect, making the whole house different in style. But you know what? In the process of decoration, the installation of doors and windows will directly affect the safety and comfort of home life in the future. Now, let's take a look at the professional construction methods and installation standards of system doors and windows!
Door and window opening measurement
the measurement of the opening size of doors and windows provides basic data for the design and manufacture 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 opening can be divided into ordinary opening measurement and special opening measurement.
1. Measurement of common openings
the size of the door and window opening 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 uneven or uneven walls, the actual measurement often shows the phenomenon of "different point positions and different measurement results. Therefore, we should pay attention to multi-point measurement when measuring, and measure the accurate data according to the actual situation.
The actual operation should be based on the horizontal and vertical installation of doors and windows in the opening. Due to the horizontal and vertical deviation of the opening during construction, it is necessary to use tape measure, plumb bob and other tools to find out the minimum horizontal width and minimum vertical height of the opening during measurement; Record at least 3 measuring points, the minimum value shall be taken as the standard. If the hole is irregular or has serious deviation, the hole needs to be trimmed, and then re-measured after the hole is trimmed.
(Wrong measurement method)
the selection of measuring points at the opening is as smooth as possible, and obvious convex points or concave points will seriously affect the measurement results.
2. Measurement of corner window
when measuring the corner window opening, the height measurement is basically the same as that of the regular opening, but when measuring the outer edge width (W1\W2) and the inner edge width (W3\W4), there are obvious differences. Generally speaking, the measurement width is subject to the size of the outer edge: when measuring on the front side, measure the distance from the outer corner of the top surface of the balcony to the outer wall, and record it as W1; When measuring on the side, also measure the distance from the outer corner of the balcony top to the outer wall, and record it as W2; After measuring the width of W1 and W2, the thickness of the windowsill or wall body must be measured. Because the thickness of the wall body, the selection of product series and the accurate product installation position will affect the width and size of the finished product.
3. Measurement of arc 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, measure the sizes of A1, A2 and A3 first, and then measure the sizes of C1, D2 and E3 (C1, d2, E3 and AB vertical). After recording several sets of measurement data, tracing on the computer or drawing. According to the measured points C, D and E, use smooth curves to describe the arc opening size, the more equal points the chord length is divided into, the more accurate the size of the hole depicted (in addition to the above methods, you can also draw a line on the hole with a leather cover to draw the outline of the hole, then measure the corresponding size from the paper skin).
Door and window wall installation
the installation of doors and windows on the wall is an important part of the installation of finished products. It plays a key role in the use of doors and windows and the maintenance in the future. Therefore, 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 auxiliary frame installation)
a. After the steel auxiliary frame is embedded in the blank hole, and the steel auxiliary frame is leveled on the wall, the gap between the attached frame and the hole is filled with waterproof mortar, the gap between the sub-frame and the hole should be reserved for more than 10mm. After fixing the sub-frame, apply waterproof paint between the outdoor sub-frame and the hole;
b. After the steel sub-frame is put on the wall, indoor and outdoor decoration can be carried out. The finished surface of the steel sub-frame shall prevail;
c. After the indoor and outdoor decoration is completed, the doors and windows frame is on the wall, and the window frame must be protected before it is on the wall to prevent the doors and windows from being polluted or scratched. The gap between the doors and windows frame and the steel auxiliary frame should be more than 5mm. Before the fixed connection between the door and window frame and the steel frame, the level gauge must be used to lay a good level. The level of the window frame can be adjusted through the frame adjustment parts. After setting a good level, the level can be directly connected and fixed with the steel frame;
d. After the door and window frame is fixed, the gap between the window frame and the steel auxiliary frame needs to be caulked. Polyurethane foaming agent is usually used for caulking, and then weather-resistant sealant is applied to the indoor and outdoor side of the window frame to seal it well, in this way, the installation of doors and windows on the wall is basically completed.
2. Wet installation (fixed piece installation)
the biggest difference between wet installation and dry installation: wet installation, window frame must be on the wall before wet operation, while dry installation can be on the wall after indoor and outdoor decoration is completed.
a. The protective film on the doors and windows cannot be torn off before and after the blank hole is put into the window frame, which can avoid damage to doors and windows caused by later construction; adjust the gap between the window and the wall by using the wooden cushion block, and fix the window frame after laying the level;
b. After fixing the window frame, waterproof treatment is required: fill the window frame and the wall with waterproof mortar, fill it with mortar to make the window frame stable, and then remove the wooden pad. Then apply waterproof paint between the window frame and the wall of the exterior wall;
c. After waterproof treatment, indoor and outdoor decoration can be done. Before indoor and outdoor decoration, doors and windows should be protected to prevent pollution and scratches. This step is especially important during wet installation.
