How did the wooden structure building system in China come into being? Thank you.

The emergence and formation of the wooden structure building system in China: primitive social buildings, caves, semi-caves and ground buildings. Slave social architecture, bound structure, poor stability and fixity of architecture. The stability of architecture, tenon-mortise structure and architecture in feudal society increased, but because of the strength of wood, the span could not be very large. In order to solve the problem of span, substitute wood, stacked wood and bucket wood were produced, which basically formed the wooden structure system in Han Dynasty. Suspended mountain type-roofs with two slopes, wood truss and gables, generally used for buildings. Pointed roof-a central roof with four corners, six corners, eight corners and a circle. Roll shed-a roof without a ridge. Maturity of Wood Structure Architecture in China-Tang Dynasty. Architectural examples can be represented by Beige Temple in Wutai Mountain. Expiration symbol: 1. In terms of functional use, it is suitable for various planes such as high and low, single eaves and double eaves, single-storey and multi-storey, and various roof forms. 2. Adapt to the climate of each region, such as rainstorm, earthquake, cold, heat and humidity. 3. Its mechanical properties and structural properties are rich in functions. Design and construction are often the same. In terms of design-mastering the ink method and drawing the "Du Banya" who can draw patterns-wood samples were made, such as the drawing of the lighting hall, which is divided into one foot, that is, the organization of today's scale 1: 100-the organization of the guild. 5. In order to protect wood, mineral pigments, pigments and colored glass were produced. The further development of wood structure architecture in China-Song, Liao and Jin Dynasties. Logo: 1。 The plane is more flexible, except for rectangles and squares, there are also crosses-for example, the Mani Palace in Longdong Temple in Zhengding, Hebei Province, and the Yellow Crane Tower in Song Dynasty. Precipitation enhancement-for example, Longdong and Temple Wheel in Zhengding, Hebei Province. I-shaped plane-Example: Shenggu Temple in Anping County, Hebei Province. In addition, according to the requirements of functional use, the method of moving laurel came into being-for example, Longdong Temple in Zhengding and Chuzu Temple in Shaolin Temple in Dengfeng County, Hebei Province. Declining laurel-taking Notre Dame de Jinci in Taiyuan City, Shanxi Province as an example. Plane wellhead opening —— Taking Guanyin Pavilion of Dule Temple in Jixian County, Hebei Province as an example. 2. The structure is more functional, such as the pillar is not a straight line-for example, Guanyin Pavilion in Dule Temple in Jixian County and Sakyamuni Tower in Fogong Temple in Yingxian County, Shanxi Province. Wellhead structure-Example: Guanyin Pavilion of Dule Temple in Jixian County. Fighting skill is more functional, for example, Joe and Ang are both mechanical. Multi-hinged structure —— Example: Bianhe Hongqiao in Kaifeng (see The Riverside Scene at Qingming Festival by Zhang Zerui in Northern Song Dynasty). 3. Developing to high-rise buildings can solve technical problems such as wind, earthquake, wood materials and soil endurance. Such as the wooden tower of Buddha Palace Temple in Yingxian County, Shanxi Province, Guanyin Pavilion of Dule Temple in Jixian County, and North Temple Tower in Suzhou, Jiangsu Province. 4. Forming components to realize a modular system, namely a material system. 5. Various images can be seen in the Yellow Crane Tower and Wang Tengting Pavilion in Song Dynasty, such as richer roof forms. In addition, in order to stabilize and increase the appearance, there are: side feet, lifting, closing and killing shuttle posts. Decoration, colorful paintings, murals and buildings are further combined and enriched, such as the mural of Yongle Palace in Ruicheng, Shanxi Province in the Yuan Dynasty. 6. Experience is summarized into a book, such as Architectural Style in Song Dynasty (two years of Chongning in Northern Song Dynasty 1 10 3 AD).
