The meaning of door and window cover acceptance
The base layer of the door and window cover is closely related to the quality of the door and window. Therefore, it is very carefully and timely accepted during construction. The use frequency of the door and window cover is very high. If the door and window cover is not good, it will not only affect the use, but even endanger the safety. Therefore, the acceptance of the door and window cover must be careful. What are the procedures and precautions for the acceptance of door and window covers?
Door and window cover acceptance process
1. Check the base material: select the qualified wooden keel and 15mm blockboard or MDF as the base material. Before the construction, check the flatness of the base wall to exceed 30mm. Use the corresponding measures to prevent the wall from being damaged. After the wood is used as the base layer, the cement mortar can be used to fill the surface and the surface layer can be applied.
2, check the cover laminate: door and window cover base layer blockboard sleeve material cutting base layer with dry wood to make wooden wedge fixed to the ground 5mm to prevent flooding. The cover layer is white latex and the nail is used to fix the white latex. It is forbidden to repair the panel when evenly trimming.
3, check the thickness of the door leaf: the thickness of the door leaf is generally about 38mm. The special reinforcement wood board can be treated with cross opening to prevent deformation.
4, check the door and window fan installation: door and window and the ground (surface height) distance 5-8mm door fan left and right gap 2-3mm door and door file combined with tight gap ≤ 2mm hinge position is 1/10. After installing the door fan, it is necessary to apply a proper amount of glass glue to protect the glass between the smooth surface and the frosted surface. The frosted surface should be inward to the outdoor junction.
5, check the hinge: the hinge should be installed on the door leaf and the door frame on both sides of the slot door opening and hinge tight.
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 lock hole is correct. The gap between the lock tongue and the door lock and the door frame should be strict. After the lock is installed, it must be wrapped to protect against contamination.
7. Check the sliding door: the small window rail is used for the track and window fan within 1500mm; the medium size is used for 1500-2000mm; 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 should have more than 10mm. The horizontal and vertical joints shall be uniform, tight, and the hidden sliding doors shall be closed after the door leaf is installed and the inspection is qualified.
Door and window cover acceptance considerations
installing
1, the door frame installation to see horizontal and vertical
The door frame must be installed firmly, horizontally and vertically, and the door leaf should be matched with the frame. The gap should not be too large; the side of the door frame should be treated with anti-corrosion treatment. The filling material between the frame and the wall is generally rock wool, mineral wool, sealing strip, etc. Insulation, buffering, sealing
2, the door cover installation is firm and stable
Doors and windows (door and window decoration effect diagram) When using blockboard or MDF, the base board should be fixed on the base keel of the window frame, and then the line should be nailed; the gap between the sets should be tight, flat and without dislocation; the mullion and The horizontal frame joint is at a 90-degree angle. The door frame and the door cover are fixed at a multi-point position. After leveling and vertical, the glue is filled and strengthened.
3, hinge installation avoid hammer straight nail
The hinge installation should be double-sided slotted and installed firmly. The door made of hardwood should be drilled first, then the screws should be tightened. The construction personnel should not directly screw the screws with a hammer.
4, the installation line looks accurate and high quality
Draw lines to be accurate. The first time to repair the planing should not be too much, the second time to repair the plan to do not leave the line not to eat the line, the planing is accurate, to ensure the quality of the installation. The installation of the line can be determined according to the width of the wall and the door frame. If the wall is narrower than the frame, the side with the width of the line can be used against the wall. If the frame is narrower than the wall, the cover line can be removed on both sides of the line. The line is fixed with the nail and the back cover can be returned.
5, ready to paint immediately after installation
After the production is finished, the primer should be applied once to prevent the wood from being deformed by moisture.
