The construction of the door and window cover base layer is an important part of the home improvement project. It functions to connect the interior decoration materials and has the function of protecting the edge of the wall. It can also serve as a decoration. Therefore, the influence of the shape, material and color of the door and window cover on the overall home decoration style should not be underestimated. So, how much do you know about the construction of the door and window cover? Let's study together with Jiuzheng Building Materials Network!
Pre-construction preparation
·The construction of the door and window cover needs to be carried out after the completion of the construction of the wall, door and window frame.
· In order to make the door frame skeleton more stable and firm, it can be constructed before the floor tiles.
· The wood used for the door frame skeleton is white pine and fish scale pine. The wood grade should be Grade II and Grade 3. The moisture content is subject to natural air drying. The wood is not allowed to have defects such as twisting, splitting and deformation.
• The door cover base layer is made of 9 PCT fine wood plywood; the window cover base layer is made of 15 PCT fine wood plywood, the front of the hole is made of 9 PCT fine wood plywood, the surface layer is made of 3 PCT red enamel plywood, and the negative corner part is affixed with red eucalyptus.
Construction process and quality standards
The construction process includes: inspection, positioning and scribing, pre-assembly and fixing of the ingredients in the field.
First, check the base material, select qualified wooden keel and 17mm thick blockboard or integrated board as the base material. Before the construction, check the flatness of the base wall. When the error exceeds 30mm, take corresponding measures. When the wall is damaged, after the wood is used as the base layer, the cement mortar can be used to fill the surface to complete the surface layer construction. Check the flatness of the plastering surface of the door and window frame, the opening and the installation part. For the error range, certain measures should be taken to correct it, and outside the error range, it should be rectified before it can be constructed.
Secondly, according to the design size, the line type, the installation height, the frame width, and the guaranteed margin size, the positioning and scribing is performed. At the same time, it is necessary to level and straighten the skeleton according to the size, and then install the whole or the piece, and find the straightness, and apply the wooden pad to the gap of the base layer.
Once again, the ingredients should be processed correctly, the surface is straight and smooth, the line angle is clear, the corners are square, the 45° cutting angle is neat and uniform, and there are no defects such as burrs, burrs and hammer marks. In addition, the ingredients should be pre-installed in the field before the installation, finely trimmed to make the dimensions uniform, the seams are straight and tight, the line angles are straight, and the stitching is correct and then fixed.
Finally, the position should be correct when installing and fixing, and it should not be loose. The spacing of the nails depends on the material and the section size. Generally, it should not be larger than 300mm. Pay special attention to the panel used for the same window cover. The color requirements are similar, no obvious color difference, straight texture, and similar pattern. After installation, the interface should be straight and straight without obvious error, the cutting angles are neatly intersected, the joints are tight and straight, and the wall surface is close to the wall, and the line shape is consistent.
Construction Notes
·Check the flatness, verticality, flatness and verticality allowable error ≤1mm, diagonal allowable error ≤2mm, detect the left and right corners above the door and window to the horizontal line distance, all doors should be consistent in height.
·The base layer and the bottom surface of the panel should be parallel after planing. The allowable deviation of the bumps should not exceed 0.5mm. The grease, dirt and dust on the glue surface should be removed before the glue is applied. The glue must be pressed when glued. The thickness of the joint is generally Not more than 0.3mm, no degumming or leakage is allowed. After the door and window cover layer is glued, it is necessary to carefully remove the surface glue, dust and other pollution, and then strictly polish it, and apply the base oil (or rub the oil powder) to prevent air drying deformation and surface contamination.
·The edge line and the wall should be tightly connected. The gap should be within 3mm-6mm. Use special sealing glue to make up the seam. If it is more than 6mm, it should be filled with 9cm board base layer and then seal with seam glue.
·The door and window cover base layer blockboard is horizontal and vertical, and the base layer is fixed with wooden wedges with dry wood, 5mm from the ground to prevent water immersion.
·The cover layer is fixed with white latex and nails. The white latex should be evenly applied. When trimming, it is strictly forbidden to repair the panel.
· Make curtain boxes according to the requirements of the room and drawings. If the curtain rods are directly installed without the curtain box, when installing the curtain rods, pay attention to the opening distance of the window frame and the thickness and length of the curtain rod; when making the panel curtain box, First make a 7-shaped frame nailed to the top, both sides are sealed with wood board, and a 20mm×18mm wooden strip is used to reinforce and nail the vertical frame lower to prevent deformation, and to re-seal the water paint. For the decorative panel, the surface of the base layer must be smooth and smooth.
·When the window cover is made of blockboard or MDF, the base plate should be fixed on the base keel of the window frame, and then the line should be nailed. According to the "Zigzag" nail, the line should be curled, the angle should be dense and flat, and the window cover should be tight and flat. Marble should be used at the lower mouth to avoid blackening due to moisture.
• The door cover should be framed with wood, planed and straightened, then assembled on the wall and then covered with the base plate and veneer.
·The edge of the frame must be carefully selected to ensure that the front line texture and color balance are beautiful. The edge must be polished before use. The front and back sides are the same as the primer. When the line is nailed, the back side must be leveled and then glued a little, and nailed. .
Link: About door and window fans and their installation
·The thickness of the door leaf is generally about 38mm, the lock should be specially reinforced, and the wood board can be treated with cross opening to prevent deformation.
·Door and window fan installation: the distance between the door and window and the ground (surface height) is 5mm-8mm, the left, right and upper mouth of the door leaf is 2mm-3mm. The door leaf and the door file are tightly combined, and there is no light transmission. The gap is about 1mm or so. The page spacing is 1/10 of the height of the stand. When the door leaf involves frosted glass, after installing it, apply a proper amount of glass glue on the smooth surface to protect the glass. The frosted surface between the kitchen and the bathroom should be outward, and the frosted surface should be inward with the outdoor junction. When installing the hinge, the door leaf and the door frame must be grooved on both sides, and the door opening and the hinge are tight. After the door leaf is installed, it must not be higher than the edge thickness. The switch should be flexible after installation.
·The height of the door lock is 900mm-1000mm (lock center position), the position of the keyhole is correct, the lock tongue and the door leaf, and the gap between the lock and the door frame should be tight. After the lock is installed, it must be wrapped to protect against contamination.
·Sliding door: The small window rail is used for the track and window fan within 1500mm; the medium size is used for 1500mm-2000mm; the large slide rail is used for 2000mm or more. When determining the width of the double-single double-track sliding door leaf, the intersection of the two door leaves shall have more than 10mm overlap, and the horizontal and vertical gaps shall be uniform, tight, and the hidden sliding door shall be closed after the door leaf is installed and the debugging is passed.
·Spring door: When installing the fan, the door shaft should be drilled in the door frame, and the ground spring should be buried in the ground. The upper and lower shafts should be on the same vertical line. The ground spring should be buried flush with the ground. The concrete is filled and smoothed, and the ground spring fan and the door fan are tightened on both sides.

2, according to the size of the outer wall of choice, standard size, unfavorable to the construction, better reflect the decorative effect. Good deviation of the specifications, paving the tidy uniform, brick straight, decorative effect is good. Dimensional error is greater than 0.5 mm, flatness greater than 0.1 mm of product, unfair to increase the difficulty of construction, while the decoration effect is poor. Whether the size meets the standard can be judged by the target. The bricks placed on a flat surface to see whether the four sides of the flat surface exactly match, at the same time, to see whether the four corners of the tile are right angles. Good newspaper no bump, bulging, Qiaojiao and other defects, the side of the error does not exceed 0.2-0.3 mm, the thickness of the error does not exceed 0.1 mm.
3, according to the exterior wall pattern selection, good ceramic tile pattern, pattern color clear and consistent, exquisite craftsmanship, no obvious leak color, dislocation, broken or inconsistent depth.
4, a careful observation of whether the color difference of the external wall tiles, color tiles, is directly related to the decoration effect. Not a batch of products, or the same batch may have color, therefore, in the purchase process, for each packaged product sampling comparison, the tiles placed in the same species and the same type of brick, observe its The degree of color difference, a good product color is small, the basic color tone between products, bright color uniform, brilliant, and poor product color larger, the product shades of color.
