Introduction to the characteristics of wooden structure houses and villas in Chongqing

Historically, Chongqing wood-frame houses have been widely used in residential, religious, cultural and monumental buildings. In addition to this, wood structures are also used in large structures such as bridges. In the long history, wood, as a practical building material, has condensed the great ideas of countless human beings, and has become a medium for the dialogue between human beings and the natural environment. In the long history of the development of wooden structures, people have accumulated a wealth of architectural knowledge such as construction technology and construction technology, created an immortal wooden structure culture, and left a splendid page in the history of architecture. In China, wood structure has a long history, but due to the rational development of modern wood resources and the low processing capacity, the application of wood structure in China is rare. With the development of an environment-friendly economy, under the new situation of energy shortage and severe environmental protection situation, we need to re-examine this new structural system. As a form of construction, modern wood structure buildings have been widely recognized in various aspects in North America and around the world due to their excellent energy-saving and environmental protection characteristics, rapid construction speed, comprehensive cost and economy. Chongqing wood structure housing system can be divided into wood frame structure and heavy wood structure. The two structures exhibit large differences in the size of the timber elements, the combination, the combination of timber elements and other materials, and the different fire safety conditions. Currently, the widely used and proven technology is light wood construction, which can be built on site or prefabricated in a factory and then assembled on site. Lightweight timber buildings are usually constructed first on a concrete foundation, with foundation cushions installed on the foundation and foundation wood, with special treatment for waterproofing and termites, and then the building's structural frame, usually the floor, is built. Beams, top beams, roof rafters, wall keels, and wood planks are used as cover plates. Wooden boards and structural parts are connected with nails, beams and load-bearing walls are connected with lightweight metal parts. After the structural parts are completed, the outer walls are decorated with wood-based panels or other materials, while the inner walls and top surfaces are made of gypsum board. Chongqing wood structure houses have strong toughness. Due to the box structure of the wood house, the force is uniform, the structure is light, and it has strong resilience. It has strong resistance to instantaneous impact load and periodic fatigue damage, so it absorbs less seismic force in large earthquakes, and the structure can be reset by its own elasticity when the foundation is displaced. As for collapse. The results show that the structure has seismic stability and structural integrity under various extreme load conditions, and the wood structure in the structure has good seismic performance. The cabin structure is light, resistant to settlement, anti-aging, and fully accepts the earth's magnetic field. Wood construction is a stable, durable and durable material. Chongqing wooden houses are made of wood, which must be dried before being produced because wood is easily rotten. The growth of wood-rot fungi is not easy to control. Wood drying is a physical process. There is no impact on the environmental protection of wood.
