  • Detail

The door and window cover plays a role in protecting the wall edge line. The door and window cover can connect the closing of indoor decorative materials, and has a good decorative effect. The base course of the door and window cover is closely related to the quality of the door and window, so the construction must be very careful and accepted in time. The use frequency of door and window covers is very high. If the door and window cover is not done well, it will affect the use and even endanger the safety, so the acceptance of door and window cover must be careful

the meaning of acceptance of door and window sleeves

the base course of door and window sleeves is closely related to the quality of doors and windows. Therefore, it is necessary to be very careful and accept in time during construction. The use frequency of door and window covers is very high. If the door and window cover is not done well, it will affect the use and even endanger the safety, so the acceptance of door and window cover must be careful. What are the procedures and precautions for the acceptance of door and window covers

acceptance process of door and window covers

1. Check the base material: select qualified wood keel and 15 mm Blockboard or MDF as the base material. Before construction, check that the flatness error of the base wall is more than 30 mm. Take corresponding measures. If the wall is seriously damaged, the surface construction can be carried out only after the wooden base is made and repaired with cement mortar

2. Check the cover laminate: the base course of door and window sleeves, blockboard sheathing and blanking, and the base course is fixed firmly with dry wood wedges, 5 mm off the ground to prevent water immersion. The cover laminate shall be fixed with white emulsion and nails. The white emulsion shall be painted evenly and enough. It is strictly forbidden to repair the panel when trimming

3. Check the thickness of the door leaf: the manufacturing thickness of the door leaf is generally about 38 mm, and the special reinforced woodworking board can be used for cross opening treatment to prevent deformation

4. Check the installation of door and window leaves: the distance between the door and window and the ground (surface height) is 5-8mm, the gap between the left and right upper openings of the door leaves is 2-3mm, and the door leaves are closely combined with the door stops ≤ 2mm hinge spacing is 1/10 of the upright height. When installing door leaves involving frosted glass, apply an appropriate amount of glass glue to the smooth part to protect the glass. The frosted surface in the kitchen and bathroom should be outward, and the frosted surface at the diplomatic junction of the outer room should be inward

5. Check the hinge: when installing the hinge, it must be slotted on both sides on the door leaf and the door frame. The opening of the door leaf is tight with the hinge

6. Check the height of the door lock: the height of the door lock from the ground is 900-1000mm (lock center position). The position of the keyhole is correct. The gap between the latch and the door leaf latch and the door frame should be tight. After the lock is installed, it must be wrapped to prevent pollution

7. Check sliding doors: small sliding rails are used for tracks within 1500mm of door and window leaves; 1500-2000mm use medium size; Large slide rails are used above 2000mm. When determining the door leaf width of double leaf double rail sliding door, the intersection edges of the two door leaves should coincide by more than 10mm. The horizontal and vertical joints shall be uniform, tight, and the concealed sliding door can be closed only after the door leaf is installed and the commissioning is qualified

precautions for the acceptance of door and window covers

during installation

1. The door frame must be installed firmly, horizontally and vertically, the door leaf is consistent with the frame, and the gap should not be too large; The side of the door frame close to the wall should be treated with anti-corrosion treatment. The filling materials for the gap between the frame and the wall are generally rock wool, mineral wool, sealing strips, etc., which play the role of heat preservation, cushioning and sealing

2. The door pocket installation should be firm and stable

when the doors and windows (door and window decoration effect drawing) are made of blockboard or density board, the base plate should be fixed on the base keel of the window frame first, and then nailed with lines; The gap between the sheathing plates should be tight, flat and without dislocation; The junction of mullion and transom forms a 90 degree angle. The door frame and door pocket are fixed with multi-point support. After leveling and verticality, they are filled with glue to strengthen firmness

3. The hinge installation should not be directly nailed with a hammer

the hinge installation should be slotted on both sides and installed firmly. The door made of hardwood should be drilled first and then screwed. Strictly supervise the construction personnel not to use a hammer to directly screw in the screws

4. The installation line drawing should be accurate and high-quality

the line drawing should be accurate. The first repair should not be too much, and the second repair should be accurate without leaving lines and eating lines, so as to ensure the installation quality. The installation of the line can be determined by the width of the wall and the door frame. If the wall is narrower than the frame, the side with the wide side of the line can be used to lean against the wall. If the frame is narrower than the wall, on the contrary, the cover nail strip can be taken out on both sides of the line, and the line can be fixed back with nails

5. Paint immediately after installation

after fabrication, apply a coat of primer immediately to prevent the wood from moisture and deformation

after installation

1. At first glance, the appearance is smooth and coordinated

it is required that the surface paint film of the wooden door should be smooth and bright, without quality defects such as sagging, bubbles, wrinkles, warpage, corrosion points, dead joints, and damage; The wood used for the door pocket should be coordinated with the wood and color of the door leaf. The color difference between the decorative panel and the wood line should not be large, and the tree species should be the same

2. Look at the squareness and verticality of the lines.

the vertical line/the vertical line of the door panel or the door frame is not done well, which will cause the door to fail to close. Therefore, the door leaf should be square and cannot be warped and deformed. The door leaf can just be inserted into the door and window (door and window decoration effect drawing) frame, and it is consistent with the door and window frame. If the gap between the door leaf and the frame is large, it is mainly due to inaccurate planing during installation or the door frame is not perpendicular to the ground, the door leaf can be removed and repaired again; If the door and window frames are not vertical, the gaskets in the frame plate should be aligned

3. The door frame is tightly embedded

the door frame and the mortise and groove of the leaf are tightly embedded, cemented with rubber and tightened with rubber wedge; The space between the door frame and the wall should be filled up

4. Look around the door jamb and there is no hollow drum bending

knock the side panel of the door and window jamb by hand. If there is an empty drum sound, it means that the bottom layer is not padded with Blockboard and other base plates. Such a door will not be solid and should be folded and redone. The door jamb vertical sheathing plate should be perpendicular to the ground without bending, and the door jamb line should be close to the wall surface

5. Look at the hinges. The door lock can be opened freely.

the hinges of the door should be installed firmly and the wooden door should be opened and closed smoothly; The opening and locking of the door lock should be smooth, and the two parts locked on the door leaf and the door frame should coincide. If the lock is improperly installed, the door leaf will not open and close freely. In addition, the opening direction of the door should also meet the requirements

the main things to pay attention to in this step:

1. Prevent and urge workers to protect the finished products. After entering the site, the door frame should be properly kept and stored in the warehouse. The lower part of the door storage rack should be padded 20 ~ 40cm away from the ground, and leveled. It should be stacked neatly according to its model and order of use. When it is stored in the open air, it should be covered with tarpaulin to prevent sunlight and rain

2. Check whether preservatives are used to prevent moisture deformation

the wood door frame entering the site should be treated by brushing the side against the wall with wood preservatives, and the other sides should be brushed with oil to prevent deformation after moisture
