Why do most people in Europe, America and Japan use wood to make houses, while people in China like to use cement?

In many countries in Europe and America, wood structures are widely used because of their convenient materials, and the penetration rate is quite high. In the economic powers of the United States, Canada and northern Europe, nearly 85% people live in wooden houses. In addition to residential buildings, multi-storey apartment buildings, low-rise commercial buildings and public buildings, such as restaurants, schools, churches, shops, office buildings, etc., wood structures are also used everywhere. In these countries, the industrialization, standardization and supporting installation technology of wooden houses are very mature.

In Japan, houses are built by one family, and a large number of houses are made of wood and glued wood. In addition to the high-rise buildings in the city center, the suburbs and villages are single-family wooden houses.

Wood has a good seismic effect and can reduce the secondary damage caused by disasters. As we all know, there are many natural disasters in Europe, America and Japan, such as tsunami, hurricane and earthquake. 1995 Most of the houses that survived the Kobe earthquake in Japan were wooden houses. In the earthquake in Los Angeles, the wooden villa was slightly deformed and never collapsed. Advantages of wood structure: high strength, light weight, high toughness, strong ability to resist sudden impact, complete structure, and greatly reduced secondary damage after disaster. Japanese people don't like living in tall buildings. Japan's land resources are very limited, and the land price is naturally quite expensive. Many people like to build their own wooden houses, the area is small, but if there are frequent earthquakes, the chances of escape are high.

The construction period of wood is short, which saves time and can meet the design diversity of designers. Compared with cement, the construction period of wooden buildings is about 1/2 of that of traditional buildings, that is, 6- 10 months, while the construction period of wooden buildings is 3-4 months, which greatly saves users' time. We know that in Europe and America, they like to do it themselves. Even if they build a house, they also like DIY design and construction. Both indoor and outdoor meet their own ideas and build their own unique style houses.

The wooden structure is warm in winter and cool in summer, and the seasons are like spring, like a natural air conditioner. After the Kobe earthquake, the Japanese government made it clear that all civil houses must use wooden villas in North America. At the same time, JAS building standards were implemented in Japan. Decorating the inside and outside of the house with modern building materials, reasonable design and layout, and appropriate absorption of sunlight, living in a wooden villa feels like spring all the year round, warm in winter and cool in summer, which is naturally very comfortable.

Wooden houses in North America and Japan have lived for generations, and they are in good condition, and the anti-ant and anti-corrosion projects have been done quite well. The ancient houses in China were mainly made of wood, and our Forbidden City is a typical example, which has been well preserved for hundreds of years. In America, wooden houses with a history of 100 years can be seen everywhere.

When the equilibrium moisture content of wood is lower than 19%, insects cannot survive. The average moisture content of wood used in building wooden villas is only 17%, and special pathogen-free anticorrosive materials, insect-proof nets and drugs are used at the foundation to stop the invasion of termites and keep the home away from these insects.

Low-carbon environmental protection saves natural resources, and the wood structure can be used many times. The materials used in wood structures are mainly renewable resources. From the point of view of environmental protection, it is a renewable material. As a building material, it has the least impact on the environment from production to waste. It is a low-carbon industry advocated all over the world.

Due to the large population and lack of land resources, China is dominated by reinforced concrete high-rise buildings. China's infrastructure capacity is also world-class. Different national conditions determine the demand for houses, and the building structure of houses is also different.
