1, room concealed works are embedded, wall surface works, water and electricity transformation, ceiling works and waterproof works have been completed and accepted, and room door covers have been installed.

2, the ground flatness, the standard should be every 2 meters error range of 5 mm or less; Ground moisture content, the standard is ≤ 20%; The standard of air humidity should be 40%-80%. If it is not up to standard, remind customers to balance the air humidity through humidifier or window ventilation in the future use process to reach the standard amount.

Second, the preparation work before the floor paving

1, carefully clean the ground before paving to ensure that the ground is clean, dry, stable, smooth and free of aggradation, and the uneven part of the ground should be filled in and removed to ensure the installation quality of solid wood floor.

2. Check whether the pipes and valves in the room are leaking. If there is leakage, deal with it in time before paving.

3. Because most rooms use floor heating now, in order to avoid damaging the floor heating pipes, some places on the ground can't be nailed, so these embedded pipes should be inquired with customers in advance and marked.

Third, the installation of wooden keel

Because the floor of most owners' rooms can't be completely flat, in order to ensure the flatness of the solid wood floor after paving, it is necessary to install wooden keels to level the ground; In addition, the solid wood floor can not be directly laid on the ground, and the installation of wooden keel can also increase the foot feeling of the solid wood floor.

1. If the owner's living room and bedroom are paved with solid wood floors, in order to reach the same level of paved solid wood floors, a 50 cm horizontal line should be leveled during the floor paving. If you only lay the bedroom floor, you don't need to make a horizontal line of 50 cm, but you should pay attention to the height difference between the bedroom floor and the living room tile, and the gap should not be too big. It is appropriate to adjust the height with the transition bar at the door.

2. Determine the laying direction of the wooden keel according to the incident direction of the main light of the room window and the requirements of customers. The laying direction of wooden keel should be perpendicular to the floor.

3, according to the length of the wooden keel module and the length of the floor to calculate the spacing of wooden keel, and marked on the ground. In order to ensure the firmness of the floor pavement, it is necessary to ensure that the floor joints are on the wooden keel. The spacing between wooden keels should be less than or equal to 40 cm.

4, according to the length of the wooden keel, wooden keel reasonable fixed on the ground, the hole spacing of electric drill should be below 30 cm, the hole depth should be below 60 mm, so as not to break through the floor. The diameter of the perforated cork is larger than that of the electric hammer bit, and the wooden keel can also be directly fixed with cement steel nails.

5. When fixing the wooden keel, special wooden keel nails must be used, and cement or water-based building glue is not allowed to be used for fixing, so as not to affect environmental protection.

6. When installing the wooden keel, both ends of the wooden keel should keep a certain distance, and the distance is ≤5 mm, so as to prevent the wooden keel from being deformed due to thermal expansion and contraction. At the same time, a certain expansion joint should be reserved between the wooden keel and the wall, with a length of 8 mm-12 mm.

7. After installation, the wooden keel must be kept level. If there is a gap between the wooden keel and the ground, it should be padded with hard materials, and the remaining wooden keel can be split into small pieces for padding. If the wooden keel itself is uneven, the head end of the wooden keel should be planed or padded with tools. After installation, the surface flatness error of wooden keel should reach the standard below 3 mm every 2 meters.

Four, the laying of solid wood floor

1, before laying the solid wood floor, because the wooden keel is easy to be affected with damp and insects, we should sprinkle some desiccant and insect-proof powder in the cracks of the wooden keel, and also sprinkle some camphor wood blocks to prevent the wooden keel from being affected with damp and insects. In addition, more insect powder or camphor wood blocks should be scattered in the four corners of the room.

2. If you need to use plywood as the cushion for the paving of solid wood floor, you should saw the plywood into small pieces of 1.2 mm× 0.6 mm or 0.6 mm× 0.6 mm, and then fix the small pieces of plywood on the wooden keel with wooden keel nails. After all the plywood cushions are paved, the elevation should be checked again according to the standard of every 2 meters high difference of ≤3 mm or less.

3. Spread moisture-proof film on the wooden keel. The joints between moisture-proof films should overlap by 50 mm and be glued with adhesive tape to ensure the integrity and firmness of moisture-proof films. In addition, the moisture-proof films at the corners of the four walls should be rolled up by 50 mm. ..

4. Generally, the floor should be installed from the half facing the door first, so that at the end of the installation, the size of the floor is irregular. When the floor needs to be sawed for installation, because the other half of the house usually puts all kinds of furniture, the uneven floor will also be blocked by furniture, which will not affect the overall appearance.

Before installing the solid wood floor, the installer should check each floor to be installed. If there are defective products or wear marks on the floor surface, they should be picked out and not used. Finally, these floors should be packed and returned to the factory for replacement. In addition, through the inspection and selection before installation, the installer can also manually classify the patterns and colors of the floor to avoid the color difference problem to the greatest extent.

6. When laying the floor, use an electric drill to drill holes in the tongue of the floor, which is the convex groove. The diameter of the hole should be slightly smaller than the diameter of the floor nail. Generally, four holes are drilled in the floor with a length of 9 10 mm, and floor nails are screwed into the holes and fixed on the wooden keel. In order to ensure the beauty of floor pavement, staggered joints should be connected (staggered joints are the most beautiful and firm when they are more than 30 cm). The length of the floor nail should be 2.5 times the thickness of the floor. When fixed, it should be driven into the wooden keel at an angle of 30-50 with the eye.

7. The room is paved on all sides. When sawing the floor according to the remaining space slice, it is necessary to accurately measure the size with a square. In order to prevent wood chips from splashing and polluting the owner's wall and ground when cutting and sawing the floor, the floor should be made into a dustbin by using floor packaging boxes or other wastes, and the floor should be sawed in the dustbin.

8. Because the wall of the owner's room is sometimes uneven, the row of wooden floors nearest to the wall can't be fixed with nails, so it is necessary to jack up cork where the gap between the floor and the wall is relatively large, fix the floor with cork and level it, so as to make the floor pavement more solid and beautiful.

9. If the workload of paving the floor is too large to be completed in one day, the floor that was unpacked and not installed on that day should be put back in the box to prevent the floor from being damp.

V. Installation of skirting board

1. When installing the solid wood skirting line, you need to drive a cork into the wall, and then nail the cork through the skirting line, and nail a nail every 40 cm. In order to ensure the beauty of the baseboard, the nails selected should be headless. Even if a nail with a nail head is used, the nail head should be cut off before nailing into the baseboard. Finally, the nail holes left should be treated in the same color as the baseboard to minimize the construction traces.

2, Yin and Yang Angle to cut the corner to sew.

Six, install the door buckle

Because there are many pipelines at the door of the room, it is recommended to install buckles and stick them firmly with glass glue.

Seven, floor pavement construction acceptance

1, floor paving acceptance: check the flatness of the floor surface, and use a two-meter guide rule and a feeler rule for acceptance. The standard is that the error value is within 0.3 mm every 2 meters; Check the height difference of flat-fell seam of two floors, and the standard is ≤ 0.6mm; Check the flat-fell seam gap between the two layers, and the standard is ≤ 0.8 mm; Check the gap between the ground and the wall and the ground fixtures (such as heating pipes), and the standard is 8 mm-12 mm; Check that the floor surface is smooth and the paint surface is free of damage and obvious scratches; There is no obvious abnormal sound in the main walking area.

2. Acceptance of the skirting line: the clearance between the skirting line and the door frame is ≤ 2mm; Spacing of flat-fell seam of baseboard ≤1mm; The clearance between the skirting line and the floor surface should be within the range of 3 mm to 5 mm; The height difference of skirting board buttonholes should be ≤1mm.

3. Acceptance of the door buckle: the door buckle should be installed directly below the door, and it is advisable to leave no edges inside and outside after closing. The gap between the buckle and the bottom of the door is between 3 mm and 7 mm, and the door can be opened and closed freely. Buckle installation should be firm and stable. You can kick the middle part of the buckle with your feet to check whether the two sides of the buckle are inclined or loose and whether there is abnormal noise.
