Description :

　　What are the main uses of wooden blocks in construction projects? 1. Wooden blocks made of materials such as pine, oak, and cedar are used on construction sites. 2. Building timber, commonly known as square timber, is sawn into square strips of wood of a certain size and shape according to actual processing needs. It is generally used for decoration, door and window materials, formwork support and roof truss materials in structural construction, or for making various wooden furniture. Mainly processed from pine, oak, cedar and other trees into rectangular or square cross-section wooden strips. It is a commonly used material in decoration, with multiple models, used to support the exterior decorative panels and serve as a bracket.

　　Wet swelling and arching, surface phenomenon: the wooden floor surface partially arches upwards, or certain wooden floors arch upwards. Reason analysis: 1. Continuous rainy and cloudy weather, high relative humidity in the air, and no dehumidification measures taken. Moisture in the air is absorbed by the wooden floor and expands due to moisture absorption; 2. Wooden floors absorb moisture and expand after being soaked in water; 3. The house is left unoccupied for a long time, with poor ventilation. The water in the paint layer evaporates and is absorbed by the wooden floor, causing it to absorb moisture and expand; 4. The moisture content of the base concrete is too high, and the moisture-proof isolation layer is not sealed tightly, causing moisture absorption and expansion; 5. During the installation of wooden flooring, adjacent panels did not reserve extension joints as required, resulting in moisture absorption, expansion, arching, and even paint cracking; 6. Insufficient reserved structural joints between wooden floors and walls; 7. The area of wooden flooring is relatively large or wide, and no segmented measures have been taken. Preventive measures: Regularly open windows for ventilation; And reserve structural extension joints, segmented joints, and adjust the reserved extension joints between adjacent panels according to regulations. Cracks appear on the surface of the board, and the surface phenomenon is that small cracks appear on the paint surface of the wooden floor, which can cause severe peeling of the paint film. Cause analysis: 1. When climate change is significant, the moisture content of the wooden floor may be too high or too low, resulting in dry shrinkage or swelling of the wooden floor. The elasticity of the paint film may not keep up with the wet shrinkage or swelling changes of the wooden floor, leading to cracking of the paint film; 2. Wooden flooring may experience shrinkage due to prolonged exposure to sunlight or wind, causing the paint film to become less elastic and unable to keep up with the shrinkage, resulting in wrinkling and cracking of the paint film; 3. The wooden floor swells due to moisture absorption, and the moisture content of the wooden floor increases after moisture absorption. The wooden floor experiences moisture swelling, and the elasticity of the paint film cannot match the expansion of the wooden floor, resulting in paint film cracking. Preventive measures: Choose high-quality wooden flooring from manufacturing enterprises, ensuring the adhesion, elasticity, and wear resistance of the paint film. Solution: A small amount of paint film cracking can be repaired by touch up painting. If the cracking area is large, it can be ground flat and repainted. If the paint film of a single wooden floor cracks for a long time, the wooden floor can be replaced individually.
