Appreciation of traditional wooden houses

? ? As the name implies, wooden structure building is a building with wood as the main raw material. Wood structure architecture has been developed for thousands of years in China, but it gradually began to fade out of people's lives.

Wood structure means that the building structure is dominated by wood structure system. Wood structure system has many advantages: for example, the maintenance structure is separated from the supporting structure, and the seismic performance is high; Convenient materials and fast construction speed. ?

? However, wood structure also has many shortcomings: it is easy to be corroded by fire, termites and rain, and its maintenance time is not long compared with masonry; Due to the increase of engineering quantity, the demand for finished wood is in short supply; It is difficult for beam-frame system to realize complex architectural space. ?

As far as the choice of building materials is concerned, due to the increasingly serious environmental problems, especially the harm of acid rain, modern buildings with wooden structures are easily eroded, and the protection technology may not be as complete and professional as ancient wooden structures.

As we all know, most of the famous ancient wooden buildings are provincial-level national key cultural relics protection units, which are maintained and repaired by relevant professionals.

As far as the cost is concerned, wooden buildings are not as economical as concrete buildings. Concrete looks like cement, but most of the materials in it are actually gravel, which can be obtained locally and is cheap. But good wood is expensive and has a long growth cycle.

The most important thing is that land development is more and more strict, and land is more and more expensive, which makes developers want to build more space in a limited space, so they can only develop to high-rise, so high-rise buildings are getting higher and higher, which is also one of the reasons. There is still a certain gap between the bearing capacity of wooden buildings and concrete, so wooden buildings are not suitable for building high-rise buildings.
