Construction method and installation standard of system doors and Windows


System construction method and installation of doors and Windows standard: doors and Windows is a complete organic combination of the performance of a system, demand more water tightness, air tightness and wind resistance, mechanical strength, heat insulation, sound insulation, anti-theft, sunshade, weatherability, handle and a series of important function, also required equipment, material, accessories, glass, viscose, seal the comprehensive result of performance of each link, be short of one cannot, eventually constitute a system of high performance Windows and doors. The installation of system doors and Windows is very elegant, the following to learn the construction method of system doors and Windows and installation standards.


Survey of door and window opening


The measurement of the size of door and window openings provides basic data for the design and production of doors and Windows, and ultimately relates to the installation effect and quality assurance of doors and Windows. According to the type of hole, the measurement of door and window hole can be divided into ordinary hole measurement and special-shaped hole measurement.


1. Measurement of ordinary openings


The size of the door and window openings is mainly to measure the height and width of the doors and Windows on the left and right sides. Because the wall is uneven or not straight and so on, the actual measurement often appears "take the point position is different, the measurement result is different" the phenomenon. So you should pay attention to multi-point measurement in the measurement, combined with the actual situation to measure accurate data.


The actual operation should be based on the horizontal and vertical installation of doors and Windows in the mouth of the cave. Due to the horizontal and vertical deviation of the hole in the construction, it is necessary to find out the minimum horizontal width and the minimum vertical height of the hole with the tools such as tape measure and hanging line hammer. At least 3 measuring points shall be recorded and the minimum value shall be taken as the criterion. For the irregular or seriously deviated holes, the holes shall be trimmed, and the holes shall be measured again after finishing the dressing.

(Wrong measurement method)


As far as possible, the choice of the measuring point of the mouth of the cave should be a relatively flat surface, and obvious convex or concave points will seriously affect the measurement results.


2. Measurement of corner window


When measuring the Angle window opening, the height measurement is basically the same as that of the conventional opening, but there are obvious differences when measuring the width of the outer edge (W1W2) and the width of the inner edge (W3W4). Generally speaking, the measured width is subject to the outer dimension: when measuring the front side, measure the distance from the corner of the top side of the balcony to the outer wall, and record it as W1; When side measurement is made, the distance from the corner of the top surface of the balcony to the outside wall is also measured and recorded as W2. After measuring the W1 and W2 widths, you must also measure the thickness of the window sill or wall body. Because the thickness of the wall body and the selection of product series as well as the accurate product installation position will affect the width of the finished product size.


3. Measurement of curved Windows


As shown in the figure, first measure the string length and arc height, and then divide the string 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 measurement). Record after several groups of measured data, tracing on a computer or drawings, according to the measurement of C, D, E, with sleek curves describe the curved hole size, chord length is divided into the more uniform, depicting the hole size is accurate (in addition to the above method, also can draw lines on paper covers in the entrance of the cave, draw the outline of the mouth of the cave, and out of the paper measured the size of the corresponding).


System doors and Windows on the wall installation


The installation on the wall of door window is the main link that finished product installs, it uses to the door window and the maintenance in the future all have very key effect, because this needs to undertake operation by the professional personnel 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 (installation of steel auxiliary frame)


A. Embed the steel side frame in the blank hole. After the upper wall of the steel side frame is adjusted horizontally, the gap between the frame and the hole shall be filled with waterproof mortar, and more than 10mm shall be reserved between the side frame and the hole.


B. After the steel frame goes up to the wall, indoor and outdoor decoration can be carried out, and the finished surface shall be subject to the steel frame surface;


C. After the completion of indoor and outdoor decoration, the door and window frames shall be protected against contamination or scratching of doors and Windows. The gap between the door and window frames and the steel side frames shall be more than 5mm. Before the fixed connection between the door and window frame and the steel attached frame, the level must be marked with a level instrument. The level of the window frame can be adjusted through the border adjustment piece. After the level is marked, it can be directly connected with the steel side frame for fixation.


D. After the door and window frame is fixed, the gap between the window frame and the steel side frame shall be filled with seam filling. Usually, polyurethane foaming agent is used to fill the gap, and then weather resistant sealant is applied to the indoor and outdoor sides of the window frame for sealing treatment, so that the installation and operation of the upper wall of doors and Windows are basically completed.


2. Wet installation (fixed piece installation)


The biggest difference between wet installation and dry installation: wet installation, the window frame must be mounted on the wall before wet operation, while dry installation can be mounted on the wall after indoor and outdoor decoration.


A. Cover the window frame in the blank hole, and the protective film on the door and window cannot be removed before and after the window frame is covered into the hole, so as to avoid damage to doors and Windows caused by later construction; Use the wooden pad to adjust the gap between the window and the wall, and fix the window frame after making a good level.


B. After fixing the window frame, waterproof treatment shall be performed: waterproof mortar shall be filled between the window frame and the wall, and wood pad shall be removed after filling with mortar to stabilize the window frame. Then apply waterproof coating between the exterior window frame and the 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 scratch. This step is especially important during wet installation.
