Xi 'an Decoration Classroom Door, Door and Window Cover Engineering Construction Technology and Technology

1, check the basic materials, and select qualified wooden keel and 15_ blockboard or density board as the basic materials. Check the smoothness of the wall at the grass-roots level before construction. If the error exceeds 30_, take corresponding measures. The damaged wall is made of wood material, and the surface construction can only be carried out after leveling with cement mortar.

2, doors and windows at the grass-roots level covered with blockboard nesting blanking, fixed firmly with a dry wedge at the grass-roots level, 5_ off the ground, to prevent flooding. The covering layer shall be fixed with white latex and nails, and the white latex shall be painted evenly and fully. When trimming, it is forbidden to damage the panel.

3. Generally, the thickness of the door leaf is about 38_, and the locking part is specially reinforced. Blockboard can be treated with cross openings to prevent deformation.

4. Installation of door and window sash: the door is 5-8mm from the ground (surface height), the gap between the left and right doors is 2-3mm, the door leaf is closely combined with the door file, the gap is ≤2mm, and the hinge spacing is110. When the door leaf installation involves frosted glass, a proper amount of glass glue should be applied to the smooth part to protect the glass after installation. The frosted surface between the kitchen and bathroom should be outward, and the frosted surface at the junction between rooms should be inward.

5, the installation of hinges must be slotted on both sides of the door leaf and door frame, and the door leaf opening and hinge should be tight.

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

7. Sliding door: the track within the range of door and window sash 1500mm adopts small slide rails; 1500-2000mm use medium; When using a large slide rail of more than 2000 mm, when determining the width of the door leaf of the double-track sliding door, the intersecting edges of the two doors should overlap 10 mm or more, and the horizontal and vertical seams should be uniform and tight. The hidden sliding door should be closed only after the door leaf is installed and debugged.

8. During construction, special attention should be paid to the handling of the door cover and door leaf, which should be flat and smooth.

9. When swinging a spring door, drill the door shaft on the door frame and dig a hole to bury the spring. The upper and lower axes should be on the same vertical line, the floor spring should be flush with the ground, filled with fine stone concrete, and the floor spring rocker and door leaf should be tightened on both sides.

10, the bottom plate of the door cover is not allowed to be spliced horizontally, and the whole plate is 2-3 in the longitudinal direction, leaving a seam of 2-3 mm for splicing, which can prevent the deformation of the base.

Acceptance criteria:

1, the allowable error of the verticality of the door cover is ≤ 1_, the allowable error of the diagonal is ≤2_, and the doors of the same type should be highly consistent.

2. Installation of door and window sash: after installation, the switch should be flexible, the door should be 5-8mm away from the ground (surface height), the gap between the left and right sides of the door leaf and the upper opening should be 2-3mm, the door leaf should be closely combined with the door file, and the gap should be ≤ 2 mm, and the thickness of the door leaf should not be higher than the sideline after installation.

3, hinge installation position is appropriate, reliable fixation, complete screws, no turning embryo, no slippery thread, smooth and firm. The door touch is firmly installed and fixed, and the position is reasonable.

4. The height of the door lock from the ground is 900- 1000mm (lock core position), which is firmly installed and can be opened freely. The lock is free from contamination and scratches.

5, sliding door open freely, easily, without scratches, horizontal and vertical seam should be uniform and tight.

6, doors and windows surface clean, no scratches, bumps, erosion.
