Wood floor construction and acceptance: 1, the construction specification of wooden floor: The environmental requirements of paving wood floors include the completion of construction of the ceiling and inner wall. Windows, doors and glass are all installed. The interior walls have been drilled and the wooden molds for the skirting boards are fitted. The distance and position of the wooden molds are accurate. _ The operating procedures of the wood floor solid paving method are: grassroots cleaning → bombing, leveling → drilling, installing embedded parts → installing wool flooring, leveling, planing → nailing floor, leveling, planing → nailing baseboard → planing , Grinding → Paint. The operation procedures of the wooden floor empty shop method are: grassroots cleaning → elastic line → drilling installation embedded parts → ground moisture, waterproof treatment → installation of wooden keel → pad insulation layer → elastic line, nail mounted wool flooring → leveling, planing → Pin wooden floor, leveling, planing → loading skirting board → planing, sanding → paint. The requirements for the quality of wood floor pavement are as follows: The surface layer is planed smooth, no planing marks, flaws, burrs are visible, and the pattern is clear. The floor paving direction is correct, the gaps in the seams are tight, the joints are staggered and the surface is clean. The color of the clear oil surface is uniform, the surface is smooth, there is no curling drum, and the joint with the skirting board is tight, and there is no empty drum sound when walking. 2. Technical essentials of wood floor construction: Wooden floor construction is a highly professional construction project. In addition to the operation of wood flooring in accordance with the standard procedures, it also pays attention to the following specific issues: (1) After all the wooden floors have been transported to the construction site, they should be unpacked and stored in the room for more than one week so that the wooden floor can be used in accordance with the room temperature and humidity. (2) The wooden floor should be selected before installation and the defective products with obvious quality defects should be excluded. The same pattern of color patterns spread in the same room, there is a slight lack of quality but does not affect the use, can be placed on the bottom of the bed, cabinets and other furniture to use, the thickness of the same room must be the same. At the time of purchase, it should be purchased at the expense of a 10% increase in actual paving area. (3) The keel of paving wood floor should use pine, fir and other non-deformable tree species, and the back of wooden keel and skirting board should be treated with antiseptic. (4) Paving solid wood floors should be avoided under heavy rain, rainy weather and other climatic conditions. It is best to keep the indoor temperature and humidity stable during construction. (5) The wooden floor in the same room should be finished at one time. Therefore, sufficient auxiliary materials should be provided, and the finished product should be protected in time to prevent oil pollution, fruit juice and other contaminated surfaces. The glue that has been squeezed out during installation must be wiped off in time. 3, wood floor construction acceptance: The materials and grades of wood flooring are in line with the design requirements. The moisture content should be about 10%. The keel and studs should be treated for anti-corrosion treatment. The wooden keel should be firmly and flatly installed, and the spacing and fixing method should meet the specification requirements. Solid, no loose, firm paste, no empty drum, the use of plastic varieties meet the specification requirements. Visually inspect the surface of the wooden floor for planing, grinding, no scars, blemishes, and burrs. The pattern is clear, the color of the oil surface is the same, the direction of the pavement is correct, the surface seams are tight, the joints are staggered, and the surface is clean. The skirting boards have tight joints, smooth surfaces, and a uniform height and wall thickness. Checked with a 2-meter ruler, the ground flatness error is less than 1 mm, the gap width is less than 0.3 mm, the mouth plate straightness error is less than 3 mm, and the seam straightness error is less than 2 mm. 4. Common quality problems and treatment methods for wood floor construction: The common quality problems in the installation of wooden floors are empty drums, uneven surfaces, weak joints, and local drums. (1) The sound of empty drums: The reason is due to the fact that it is not fixed. The main reason is that the number of hair boards and keels, hair boards and floor nails is small or the nails are not firm. Sometimes it is caused by shrinkage of the moisture content of the board or the glue is not qualified. Caused. In addition to the strict inspection of the moisture content of the board, adhesives, etc., can only be used after the inspection is completed. 4 The nail should not be too small during installation, and be sure to be nailed. After installing one board, use foot to inspect and then install a piece of sound. , if any sound should be reworked immediately. (2) The surface is uneven: The main reason is the unevenness of the grass roots or the deformation of the floor planks. During the installation and construction, apply a level ruler to level the surface of the keel. If it is not flat, adjust the surface of the keel. Ventilation slots should be made on the keel. A 10 mm ventilation gap should be left on the board margin wall. The insulation material must be dry to prevent arching after the floor is wet. The flatness of the wooden floor surface should be within 1 mm. (3) Slotted joints: In addition to the non-standard installation during construction, the large width and size of sheet metal and poor quality of the mouthpiece are also important reasons. In addition to the careful inspection of the floor quality during the construction, the installation shall be Meikou. To nail nails in front of the board and use the module to mold the floor gaps and nail them. (4) Partial warping: The main reason is that in addition to moisture deformation of the board, there are also small or seamless seams on the wool board, which is caused by leakage of water in the floor and wet floors. In the construction period, 3 mm gap should be left when installing the wool board, and wooden keel carved ventilation slots. After the floor is covered, the paint on the floor paint should be complete. In daily use, water should be prevented from flowing into the lower part of the floor, and the surface water must be cleaned in time. 5. Estimated duration of wooden floor construction: Wood floor construction is a highly technical project and should not be paralleled with other projects. It usually takes one week to complete the construction task of three rooms and two halls, in which the wooden keel is installed and the base layer is protected from moisture for two days. The fur boards and the floor are installed for two days. The floor surface is polished and polished for one day, and the floor paint is applied for two days. The actual paving method requires less labor than the empty paving method, and the floor specifications are larger than those of the small-size ones. The elements of the quick-drying of the floor paint are slower than the elements and the specific time should be determined according to the construction method, materials, etc. Nature Flooring Del Floor Paint Room Cement Marble Interior Finishing Floor Tiles Marble Tiles Glass Tiles Glass Doors Glass Furniture Tiles Tile Floor Tiles Tiles Specifications Measuring Tape,Small Tape Measure,Custom Tape Measure,Personalized Tape Measure SHANGQIU CHAOYUE MEASURING TOOLS CO., LTD , https://www.equipmentool.com
