Summer vacation has arrived, and family travel has become the main consumer for the past two months. Accommodation in major cultural and tourism attractions is also in short supply. Building a 100 square meter house, from foundation to roof, takes three to four months, and the golden period of tourism is fleeting. Wooden houses have become the mainstream this summer due to their short construction period. Recently, the shipment of wooden houses from Xiaoyu to multiple locations also illustrates this phenomenon. The construction period of a wooden house is about one-third of that of a traditional house. As shown in the diagram below, the construction period of a 100 square meter one story wooden house is about 35 days, while the construction period of a brick concrete house takes 3-4 months. The construction period of a 150 square meter two-story wooden house is about 45 days, while the construction period of a brick concrete house takes 4-5 months. Traditional houses are only unfinished when completed, while wooden structures are mostly decorated after completion, requiring only personalized embellishments to move in. For real estate developers or homestay and tourism owners, wooden houses can greatly shorten the time for capital recovery and reduce operating costs. The wooden house is made of naturally grown wood, which is a renewable resource that cannot be replaced by any building material. The levels of Fenduojin and negative ions (air vitamins) in wood are several hundred times higher than those in reinforced concrete houses. Fenduojing and negative ions can kill bacteria in the air, curb human diseases, enhance immunity, and have significant effects on refreshing the mind, improving memory, lowering blood pressure, stabilizing nerves, and prolonging life. The biggest difference between wooden houses and brick concrete and steel-concrete houses is comfort. For example, no matter how luxurious the decoration of a brick and concrete residential building is, after a period of time, people will feel cold and damp when they don't live there; From the day of completion, wooden residential buildings are very comfortable to move in, and no matter how long they are vacant, there will be no discomfort like brick and concrete houses. Wood is lightweight and high-strength, so the energy generated by ground acceleration on wooden buildings is not as large as other buildings. Another additional advantage of the wooden frame system is its superior flexibility compared to other materials, which can absorb and dissipate energy. The wooden frame consists of three parts: the vertical studs that form the wall skeleton, the horizontal joists that form the floor slabs, and the rafters or rafters that support the roof. When the wall is made of slant support boards or lightweight wood based boards to form a wall cladding, it has lateral resistance, and then forms a shear wall system - lightweight, high-strength, and high construction efficiency. All components work together to support the building, making it resistant to gravity, wind, and earthquakes. When wood is exposed to fire, a carbonized layer will form on the surface of the wood. Its low conductivity can effectively prevent flames from spreading inward, ensuring that the entire wooden structure is not damaged for a long time. The temperature of a building fire is approximately between 700-900 degrees Celsius. When the temperature rises to 230 degrees Celsius, the strength of steel decreases sharply, and at 750 degrees Celsius, its strength is only 10% of its original level. Wood only burns when the temperature reaches 250 degrees, and once it catches fire, it typically carbonizes at a rate of 0.64 millimeters per minute under intense fire conditions. The carbonization layer naturally isolates the wood from the outside world and increases the temperature that the wood can withstand. Therefore, in a 30 minute fire, only 19 millimeters of each exposed surface of the laminated wood was lost due to carbonization, while the vast majority of the original cross-section remained intact. People often mistakenly believe that water is the enemy of wood, but in fact, wooden buildings can have long-term performance in rainy or humid areas. They can absorb excessive moisture in humid seasons and release the absorbed moisture in dry seasons to maintain indoor moisture balance. Wooden houses can be made corrosion-resistant and moisture resistant because the wood used as wall components undergoes drying treatment before leaving the factory to keep its moisture content below 14%. In this way, its moisture resistance can even reach about 10 times that of brick and concrete structures.
