What are the advantages and disadvantages between the wooden house structure and steel structure and traditional brick and wet structure?
1, short construction period: the construction period of wooden house is about 1/2 of the traditional house, which provides the fastest capital return time for the developer. The construction period of traditional house is 6-10 months, while the construction period of wood structure is 3-4 months. When the traditional house is completed, it is a rough house, while the wood structure is a well-decorated and ready-to-move-in home.
2. Flexible design: wood frame houses are more flexible in room design, easy to change the structure, and don't have to stick to many limitations of traditional houses, thus providing great convenience for developers to adapt to the market and develop new house types.
3, low conductivity: wood is a very good insulator, low conductivity, its thermal insulation and cold performance are very good, compared to the wood structure than the steel structure of the performance of 15% -70% (minimum and maximum value), can save consumers the air conditioning of the electricity or gas bills. This is a very good selling point for developers.
4, not afraid of fire: wood has a charring effect, in case of fire, the wood surface will form a charred layer, and its low conductivity can effectively prevent the flame from spreading inward, thus ensuring that the whole structure will not be damaged for a long time. The excellent thermal conductivity of steel structure will lead to rapid heating, softening and falling of the whole structure.
5, no water condensation: in the four seasons or hot and cold temperature difference in the region, the steel structure will be due to internal and external temperature difference causes condensation vapor, thus water corrosion of other insulation and other materials, over time, will have a negative impact on the entire structure. This is also one of the reasons why steel structure is rarely used in developed countries such as the United States and Japan for residential housing. Wooden structure does not have this hidden danger. Wooden structure itself is better balanced than other structures, the physical properties of wood after treatment is stable, will not be easily deformed or chemical reaction.
6, seismic best: wood structure in the world many big earthquakes has fully demonstrated its excellent seismic resistance. The toughness of steel structure and its ability to resist earthquakes cannot be compared with wood structure.
7, clean and safe construction: Compared with steel structure, the construction period of wood structure is short, the construction is clean and simple, there is no waste material such as sewage and iron filings, no big noise, no welding operation, which is safer.
