Advantages of wooden structure houses

Wood is a natural and healthy material with urgent affinity, and the wooden villa is an environmentally friendly and healthy high-grade residence. Excellent thermal insulation performance, energy saving more than 40% compared with ordinary brick-concrete buildings. Its thermal insulation performance is 400 times that of steel and 16 times that of concrete. The research shows that the thermal insulation performance of 150㎜ thick wooden wall is equivalent to that of 6 10㎜ thick brick wall.

Wood is the first choice for "green building". In the era of decreasing fossil fuels and rising costs, light wood frame construction has obvious advantages compared with other building materials. The energy consumption of wooden building materials is lower than that of steel or concrete, both of which need to be refined and manufactured at high temperature. The wooden house is made of all solid wood and is called "the house that can breathe". Indoor air contains a lot of Fendoline and negative ions, which are called air vitamins. Fantacin and negative ions are favored by modern forest bathers, which can effectively kill bacteria in the air, prevent diseases, enhance immunity, and have obvious effects on keeping the brain awake, improving attention, lowering blood pressure, calming the nerves and so on. Radon, a harmful gas in the wooden house, emits very little and is harmless to human body; Wood has little influence on energy consumption, air pollution, water pollution and greenhouse gas emissions. According to the research of Tsinghua University Institute of Building Environment and Equipment Engineering, it is concluded that wood structure buildings are 5.3% more energy-saving than light steel structure buildings and 8. 1% more energy-saving than concrete structure buildings. In the life cycle of a building, it can save about 6% of the operating cost compared with ordinary concrete roofs. It is possible for light wood frame construction to greatly reduce the heating and cooling costs within the service life of residential units. Compared with other building materials such as steel or concrete, the holes in the wood structure make the wooden house have excellent thermal insulation performance. There are spaces between the frame structures in light wood frame construction, which can accommodate thermal insulation materials, reduce heating and cooling costs, reduce fossil fuel consumption, and maintain a comfortable temperature in an economical way. With its beautiful architectural modeling, exquisite design, returning to nature, enjoying it, reasonable structure, exquisite workmanship and quick construction, wooden buildings make people feel far away from the noise of reinforced concrete components and enter a clean and pollution-free world, which is called wooden buildings. In fact, wooden buildings are not new things in the world. In Japan, almost half of the buildings are made of wood, and wooden buildings in Europe and America can be seen everywhere.

Even in China, the ancient Forbidden City can prove the long history of wooden architecture. In recent years, with the development of wooden buildings in the world, wooden buildings have reappeared in the China market and gradually entered the growth stage.

Among the many advantages of wood structure building, the most important one is energy saving and environmental protection. The wood frame wall and roof truss system consists of wood specification materials, wood structural composite plates and thermal insulation materials. According to the test, the thermal insulation capacity of 150㎜ thick wooden frame wall is equivalent to that of 6 10㎜ thick brick wall. Compared with concrete structures, wooden structures can save energy by 50%-70%. Among all the main building materials, wood is the only renewable building material. From the aspects of energy consumption, greenhouse gas, air and water pollution, exploitation of ecological resources, etc., the environmental protection of wood structure is much better than that of brick-concrete structure and steel structure, and the material has good permeability, which is easy to keep the indoor air fresh. It is recognized as a green building. In addition, the wooden structure building has the advantages of flexible design, short construction period and easy transformation. Ordinary people may think that the wooden house is lighter and more beautiful, but it is not heavy enough when it is strong, which will affect the service life of the house. In fact, modern technology has effectively solved the problems of fire prevention, earthquake resistance, wind resistance, sound insulation, insect prevention and corrosion prevention of wood structures, and also extended the service life of wood structures to 50-200 years. At the same time, its stability is quite good. According to reports, in the Kobe earthquake in Japan 1995, most of the houses preserved were wooden houses.

In the impression of ordinary people, wooden houses are only suitable for building villas. Therefore, in China, a country with very limited land area per capita, the promotion of wood structure is facing certain problems. But in fact, the wooden structure building is not only suitable for single-family houses, but also suitable for multi-family houses. It is reported that the Canadian Wood Industry Association cooperated with the China Municipal Government to introduce mixed structure technology, which not only used concrete, steel and other building materials in the wood structure. Combining the wood structure with the current building model in China can improve the energy saving and comfort of buildings, meet the needs of buildings with four floors or more, and provide an opportunity for the wood structure to enter the multi-family residential property in China.

According to reports, in Shanghai, Qingdao, Shandong, Yingkou, Liaoning and other places, the mixed structure construction technology has been applied to the "flat to slope" project, which can solve the problems of insufficient bearing capacity and narrow space of the building foundation to some extent. At the same time, due to the light weight of wood structure, it can be designed to meet the requirements of any building, so it is completely feasible to apply wood structure in actual construction, and it can also save a lot of energy, and the sales income of this part of wood structure space can also offset the reconstruction cost of the building, which can be described as many benefits.

Of course, in addition to residential buildings, wooden buildings also have quite broad application space in entertainment and commercial facilities. Although the current cost of wooden buildings is relatively higher than that of ordinary buildings, with the expansion of market share and further improvement of technology, their prices will be more and more accepted by ordinary consumers. It is believed that there will be broad development space for wooden buildings in China. 1. energy consumption comparison: after comparing the energy consumption in the process of manufacturing, transportation and installation, the results show that the wood structure has the lowest energy consumption among several structures. The steel structure is 2.4 times that of the wood structure.

2. Comparison of greenhouse effect: The results show that the greenhouse effect of wooden buildings is the lowest. Steel structure is 1.8 times that of wood structure.

3. Comparison of air pollution index: The results show that the pollution index of wood structure is the lowest, and the steel structure is 1.42 times that of wood structure.

4. Comparison of water pollution index: The results show that the pollution index of steel structure is 120 times that of wood structure. 5. Comparison of solid waste: The research shows that the wood structure produces the least solid waste in the process of production and construction. The waste of steel structure is 1.36 times that of wood structure.

6. Utilization of ecological resources: According to comprehensive evaluation, wood structure resources are the least, and steel structure is 1. 16 times that of wood structure.

Impact of building system on environment —— Conclusion: Wood structure has the least adverse impact on environment.
