Suspension Laying Method: The most popular and scientific laying method.
Keel laying method: traditional and popular laying method.
The laying method of the keel floor keel: Add a layer of 12-22mm multilayer plywood or softwood on the keel, and lay the floor again.
Direct paste laying method: Suitable for floors less than 350mm long and requires a level surface.
Each of the above four laying methods has its own advantages and disadvantages. Users and construction units should choose due to their needs due to people, place, and function.
According to the actual conditions and usage habits of our civil residential buildings, suspension laying and keel laying are recommended.
Suspension paving method Suspension paving method is applicable to the floorboards of the enterprises with high-quality, double-mouthed floors, and all kinds of solid wood floorings. Should generally choose the tight groove, bottom seam smaller floor. The advantages of this laying method are very prominent: simple laying, greatly shortened duration; no pollution, the floor is not easy arching, tile-shaped deformation is not easy; easy maintenance, floor from the seam, or local accidental damage, easy repair and replacement. Even if the moving or accidental running water is soaked, the dry floor can still be laid after dismantling.
1, the basic level processing
(1) The base level requires a smooth, dry, clean surface. If there is a small area slope or recess after leveling, it can be smoothed with gypsum binder and grinded with coarse sand, and the surface will be cleaned and dust and other impurities will be removed. Strive to be flat and do not seek smoothness. The flatness of the grass-roots level is relatively high and should be less than 5mm/2m, otherwise the floor can not reach the standard after laying.
(2) If it is laid on the ground floor or bungalow, it shall be treated with a waterproof layer. Its methods are, surface coating waterproof coating or agricultural film. When using agricultural film, the two-layer laying method is used. That is, when the first layer is laid, the film overlaps with the film by 20 cm. When the second layer is laid on the first layer of film, the joints must be staggered, and the wall must be upturned by 5 to 6 cm (below the skirting board). ).
2, cushion laying cushion material:
1) Foam pad: foam pad with thickness of 3mm with plastic film, butt laying, plastic interface.
2) bedding treasure: thickness 6 ~ 20mm. General election 10 ~ 12mm thick, butt laying, plastic interface.
3) High-quality multi-layer plywood: Thickness 8 to 18mm. Generally choose 9 ~ 12mm thick. Each piece of multi-layer plywood should be divided into small pieces, the area should be less than 0î€7 square meters, it is best to use paint anti-corrosion, and then use electric hammer, pneumatic nails fixed on the ground, must be firmly fixed on all sides, between the board and the board to stay 3 ~ 6mm gap, sealed with tape.
3, floor pavement
(1) The direction of the paving floor is usually consistent with the direction of walking of the room or according to the user's requirements, paving gradually from left to right or from right to left. The groove is placed on the wall, and the wooden wedge is placed between the floor and the wall. Full expansion joints. In dry areas, the floors are wet and the expansion joints should be small; in damp areas and the floors are dry, the expansion joints should be large. Pull the line to check the flatness of the floor being laid, and follow the inspection along with the installation. In the trial shop should observe the board surface height difference and gap, at any time to adjust, check qualified before sizing installation. General on the edge of 2 to 3 rows, apply a small amount of D4 or water-free green plastic can be fixed. The rest of the middle part is completely meshed with the tongue and groove without gluing.
(2) The last row of floors is to be cut, glued by measuring its width, and held tight by pulling hooks or screws.
(3) In some particularly humid areas such as East China, South China and South Central, when installing flooring, the floor and floor should not be too tight (usually between floor and floor to store a loose business card quasi). In the northeast, northwest, and north China, it is generally better to lay between floors.
(4) Close the bridge and install it in the interface between the room, hall, hall, the floor must be cut off, leaving enough expansion joints, using the closing strip, hardware bridge convergence. Doors and floors should be spaced 3 to 5mm apart so that the doors can open and close freely.
(5) Skirting board The thickness of the optional skirting board should be less than 15mm. When installing the floor expansion joint gap within 5 ~ 12mm, should be filled with polystyrene board to prevent the floor loose. Install the skirting board and be sure to cover the expansion joint. If the wall or foundation is uneven, cracks appear to be expected. Please decorate the wall.
The keel laying method, also known as the wooden grille method, is the most traditional method of laying floors. All the floorboards, as long as there is sufficient bending strength, can be laid with this method.
1, before laying
(1) keel purchase: a. wood keel; b. plastic steel keel; c. aluminum alloy keel.
The latter two types of keel-based new materials not only maintain the advantages of laying wooden keels with flexibility, but also overcome the difficulties of laying and the long construction period. It is more convenient to dismantle, replace, and maintain the floor, and it is the same as the suspension laying method. advantage.
Wood keel materials can be used larch, white pine, Korean pine, fir, or waste flooring and other materials. Its scale is based on the agreement between the supply and demand sides, generally 20mm × 40mm, 30mm × 50mm, 40mm × 50mm and so on. The moisture content should be consistent with the local moisture content. Advanced anti-mold, insect-proof, water-proof and waterproof anti-keel can greatly increase the life of the keel.
(2) Grass-roots ground treatment: The base-level treatment requires smooth, dry, clean, and shovels are used to flatten the bumps. If there is a large area of ​​the recess, which affects the smoothness of the keel, it must be filled with a cement mortar and be leveled and dried for more than half a month. After passing the inspection, surface dust and other impurities are removed.
2, lay the keel
(1) Floor marking: According to the floor laying direction and length, the keel laying position is calculated. Each floor is placed on at least 3 keels, generally not more than 350mm apart.
(2) Wooden keel fixation
1 wooden keel fixed: according to the actual situation on the ground to determine the hammer drilling position and spacing.
If there is a leveling layer on the ground, use a hammer drill. The average hammer hammer depth is about 25mm or more. If the nail is used to penetrate the concrete through the wooden keel, its depth must be greater than 15mm. When the ground level difference is too large, it should be leveled with a screed. The studs were first fixed to the concrete base with nails, and the wooden keel was fixed on the studs with iron nails.
2 Attention: Between the keel, the distance between the keel and the wall or other floor materials should be 5~10mm. The keel end should be nailed.
3 Wood keel leveling: After laying, the wooden keel is subjected to a full straightness test and a firmness test. After passing the test, it can be laid.
4 If there are water pipes or ground heating facilities under the ground, they must not be scratched. Generally, suspension laying method can be used. In case you have to use keel laying, you can use new steel keel, aluminum alloy keel and other new keel, or use adhesive to bind short wood keel.
3, floor laying
1 The floor covering is generally laid out in a wrong position. After leaving a gap of 8mm from the side of the wall, the first row of wooden floor is laid, the floor is convex outwards, and the floor is fixed on the wooden keel by threaded nails and nails. Tighten each block tightly. 2 Every part of the floor that touches the wooden keel must be nailed with an air gun nail, a threaded screw, or an ordinary nail. With 45°-60° diagonally, the length of the nail must not be shorter than 25mm.
3 In order to make the floor even and straight, it is necessary to store 3 to 5 floors per floor, that is, to draw a flat straight line and check whether the floor is straight and adjust it in time.
4) Installation of the attachments and skirting boards is the same as the suspension method.
