Wood floor is currently the most popular material in interior decoration. It has the advantages of light material, texture number, bright color, easy processing, and high grade. However, in the construction of wood floors, many quality problems will occur if the relevant regulations are not followed carefully. The common quality problems in the construction of wood flooring include: loosening and arching of wood boards, decay of wood boards, lax seams, uneven surfaces, and peeling of parquet floors. One, the loosening and arching of the wooden floor 1. Reason analysis (1) Barrier wood material is poor, such as very soft, high moisture content. The material is soft and the nails of the wood board are not firm, causing the wood board to loosen. If the moisture content is too high, excessive deformation may occur after the water evaporates. (2) Design the required barrier space to lay wet and sound insulation materials, so that the wood floor surface will swell and deform after being exposed to moisture, causing the wood surface to arch. (3) The grids and wooden floors laid on the damp concrete floor were not protected against moisture and corrosion, and the wood was deformed and loosened after moisture absorption. (4) The material of the wooden floor is poor. 2. Treatment method (1) The material of the barrier must be rigid, and the moisture content of the barrier must conform to the relevant national standards. It must be firmly bonded or nailed to the base layer. (2) If the moisture penetrates into the wood due to loosely mixed soundproofing materials, causing the floor to arch or loose, the wooden floor must be dismantled, doors and windows must be opened, ventilation should be strengthened, sound insulation materials and wood should be dried, and the large deformation barriers should be corrected. . Moisturizers should be applied to the grille, wood floor and back, and then re-flooring. (3) When the wooden floor on the ground floor of cement is arched, the already arched wooden boards shall be demolished, and convection vent holes under the boards shall be added to exclude the moisture in the lower part of the wooden boards. The damper should be painted on the opposite side of the wood grille and wood floor, and then the wood surface layer should be trimmed. 3. Preventive measures (1) Control the quality of wood flooring, choose the best wood for wood flooring, to meet the basic requirements of non-perishable, not easily deformable cracking, the best choice of fir, spruce, pine and other wood. The moisture content of wood should be strictly controlled and should generally be controlled between 8% and 12%. (2) Do a good job of moisture-proof and anti-corrosion treatment on the wooden louver and wooden floor surface. (3) Construction shall be carried out in strict accordance with the provisions in the "Construction Ground Engineering Construction and Acceptance Specifications". Each plank shall be nailed to each louver. The length of the nail shall be 2.0 to 2.5 times the thickness of the board and shall be nailed into the board diagonally from the side; the head shall not be exposed. A gap of 10 to 20 cm should be left between the surface layer of the wooden board and the wall, and be covered with a wooden skirting board. Second, the wooden floor rot quality problems 1. Reason analysis (1) There are many reasons for the decay of wooden flooring, but the main reason is that the moisture content of wood is more than 8% to 12%, and the bottom is not ventilated. The moisture exists in the wood for a long time and it is prone to decay. (2) Wood barriers and wood floors are not protected against moisture and corrosion according to the regulations. When wood is hygroscopic, decay is prone to occur without ventilation. (3) Some designs often use wet-mixed light materials for sound insulation, heat insulation, and moisturizing between wooden grills. However, after laying, the planks are often nailed when they are not yet dry, resulting in poor ventilation between the grilles. Provides the conditions for the growth and reproduction of wood rot fungi. (4) Wood rot bacteria can decompose the cellulose and lignin that make up the cell wall of wood, leading to decay of the wood. Wood rot bacteria are transmitted by mycelium contact, and their development speed is extremely alarming. However, mycelium transmission and reproduction must have the following three conditions: 1 the moisture content of wood is about 30%; 2 the environmental temperature is 15 °C ~ 20 °C is the wood hyphae The optimum breeding temperature; 3 certain air. 2. Treatment method (1) When the decay of the local wooden lining occurs, the partial floor shall be dismantled to check the cause of decay and replace the decayed wooden louver. The material of the replacement wooden barrier should be wood that is not easy to decay and is not easily deformed and cracked, such as spruce, red pine, eucalyptus, etc.; its moisture content should be controlled within 20%, and it should be treated with antiseptic, insect-proof and moisture-proof treatment; , Ventilation slot repair, to ensure that the air circulation under the floor; and then nail the board surface layer. (2) When there is a large area of ​​decay, the wooden floor and grille should be completely removed, and the ventilation holes of the bottom layer should be trimmed and increased. It is best to achieve convection. Choose a good material of wood, do anti-corrosion, pest control, moisture treatment. When the louver is installed, a gap of 30mm should be left on the wall to facilitate the moisture barrier and ventilation. Then install the scissors and nail the wooden floor.
