On the arrival and installation of doors and windows

The manufacture and installation of doors and windows is the most important process in this process. Measuring ruler is the most important ruler in the installation of doors and windows. It determines the quality and progress of the project. There is a famous saying in the industry: "Three points for manufacturing and seven points for installation" introduces the importance of door and window installation. Next, the steps of making and installing doors and windows and eight points for attention in installation are introduced.

Installation steps and precautions of doors and windows

Manufacturing and installation steps of doors and windows:

1, before making and installing formal doors and windows, check whether the size error of the door leaf is warped or deformed. You can use the comparison method of door leaf test and door bolt installation, or you can use the method of accurately measuring the size of door leaf and door bolt. Remember the door leaf size error and door bolt, and scrape it according to the door leaf size error. Repair the crack of the door on the side. If the height of the door leaf is too high, the head of the door leaf can be shaved off. If the width of the door leaf is too large, the two door frames of the door should be trimmed. The width of the head and the frame must be basically the same. For multi-storey 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 flatten the edge to avoid excessive planing until the installation and installation of doors and windows meet the installation requirements.

2. Don't use wooden window covers for window sills, which will not be completed within 2 years. Even this family has cleaned windows and stepped on pits now.

3。 After the hardware position passes through and is crossed, test the door leaf at the door bolt first, and then observe whether the door leaf is consistent with the door bolt frame and whether the gaps around it are uniform. I believe that the door leaf is installed according to the design. After installation requirements, close the lower joint with a thin wooden wedge to determine the position line of the lower hinge and the position line of another door hardware, and at the same time, the door latch frame or door frame plate and door leaf. The joint is 1.5~25mm. The seams between the door and the bolt are as follows: 5mm for the outer door and 5mm for the inner door, which is sanitary.

4. Calibration, hinge installation, lower hinge position line, etc. After removing the hardware position of the door leaf, take out the door leaf, draw the groove line according to the hinge specification of the lower hinge position, and pull it out of the well together with other hardware such as iron angle. Then, cut the door fan 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 an ordinary solid wood frame, a hinge groove should be opened at the hinge position of the bolt frame at the same time. Approximately 12mm.

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

1 During the renovation, it is best to replace the doors and windows before the next renovation, 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, tightness and aging degree of the whole door and window. Buyers should not be fooled by the concept of "low-priced plastic steel doors and windows" in the market.

2。 When buying, you must go to the formal building materials market. The processing equipment of roadside stalls is simple, so the accuracy and strength cannot be guaranteed. Especially for plastic steel doors and windows, the quality of steel lining made by roadside stalls is poor, even if there is no 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, indicating that there are not enough stable components in the material and it is easy to age and yellow.

4。 Check whether the hardware is flexible.

5。 The bottom of the sliding window frame should be equipped with aluminum slide rails for easy replacement.

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

7。 There should be a fixed part 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. Scraping strips are 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, check whether the overlap of the window sash contained in the window frame meets the standard requirements. If there are quality and safety hazards, it must be completely reworked.
