The production and installation of doors and windows is the most important process in this process. Measuring scale is the most important scale in door and window installation. It determines the quality and progress of the project. There is a famous saying in the industry: "Three-point manufacturing, seven-point installation" introduces the importance of door and window installation. Next, we will introduce the steps of production and installation of doors and windows and eight points for attention in installation.

installation steps of doors and windows

installation steps of doors and windows:

1. Before the official doors and windows are produced and installed, the size error of doors and windows should be checked, and whether there is warping deformation or not. You can use the comparison method of installing door bolts by door leaf test or the method of accurately measuring the size of doors and windows. The size error and door bolts should be remembered, and the well should be shaved according to the size error of doors and windows. On the side, trim the door and sew the road. If the height of the door leaf is too high, the head of the door leaf can be shaved. If the width of the door leaf is too large, the two frames of the door should be trimmed. It must be ensured that the width of the head and the frame are basically the same. For multiple doors and windows, the test must be installed behind the parallel ground. When trimming the joint, the installation test must be repeated, and an attempt must be made to plan the edges to avoid excessive gouging until the doors and windows are installed and installed to meet the installation requirements.

2. The window sill should not be covered with wooden window covers, and the wind, sun and rain will not be completed within 2 years. Even this family has cleaned the windows and stepped into a pit now.

3。 When the position of hardware passes through and is lined, first test the door leaf in the door bolt, and then observe whether the door leaf is consistent with the door bolt frame and whether the surrounding gap is uniform. It is believed that the door leaf is installed and installed according to the design. After installation requirements, use a thin wooden wedge to close the lower joint, and determine the position line of the lower hinge and the position line of another door hardware, and at the same time, the door bolt frame or door frame plate and door leaf. The joint is 1.5~25mm. The joints between the door and the door bolt are as follows: 5mm for the outer door and 5mm for the inner door, sanitary

4, calibration, determination of hinge installation, position line of lower hinge, etc. After removing the position of the door leaf hardware, take out the door leaf, draw the groove line according to the hinge specification of the lower hinge position, and pull out the well with other hardware such as iron angle. Then, cut out the door leaf from the position line of the installation groove (such as hinge groove and iron angle), and install the iron angle and hinge to the corresponding position. If it is a common solid wood frame, the hinge groove should be cut at the hinge position of the bolt frame at the same time. About 12 mm.

Eight points for attention in the production and installation of doors and windows:

1 During decoration, it is best to replace the doors and windows first, and then carry out the next decoration, because the indoor and outdoor walls will be damaged during the window removal process. Shopkeepers should know which brand profile to choose. The quality of this profile will determine the grade, sealing and aging of the whole door and window, and buyers should not be fooled by the concept of "low-cost plastic steel doors and windows" in the market.

2。 When buying, you must go to the regular building materials market. The processing equipment of roadside stalls is simple, which can not guarantee the accuracy and strength. Especially for plastic-steel doors and windows, the quality of steel lining steel made from small-sized roadside stalls is poor, even without lining steel, other accessories are also poor.

3。 The appearance of plastic steel doors and windows should be blue and white. The color is too white or too gray, which indicates that there are not enough stable components in the material and it is easy to age and turn yellow.

4。 Check whether the hardware is flexible.

5。 The bottom of the sliding window frame should be provided with an aluminum slide rail for easy replacement.

6。 The sealing strip of casement window should be freely replaceable, because the life of sealing strip is shorter than that of formwork.

7。 There should be a fixing piece in the middle of the sealing top of the sliding window sash, which is the key to the sealing performance of the sliding window.

8。 During installation, the horizontal and vertical alignment of doors and windows should be supervised. The scraper is filled between the window frame and the wall, and the inside and outside of the window frame must be sealed with silicon copper or sealant to prevent water seepage. After installation, the protective film must be removed, otherwise the service life of doors and windows will be shortened. It should also be noted that after installing the window sash, whether the overlapping amount of the window sash contained in the window frame meets the standard requirements is checked. If there are quality and safety hazards, it must be completely reworked.
