The difference between barrel-penetrating type and hanging beam type

Lifting beam type: (stacked beam type) is a beam frame structure system, in which horizontal members are beams, vertical members are columns, and beams are flexural members, and the building is stable by its own weight. 2. Over-bucket type: ① Also called vertical column type. (2) This is to directly support purlins with short columns, to connect the columns with ground columns with dense column spacing and small column diameter, and to connect the columns with several purlins without beam application. The disadvantage is that the indoor columns are dense and the space is not open. ④ Therefore, it is sometimes confused with the stoplog frame. Suitable for different terrains, foundation members and column purlins. 3. Completely dry type: a building structure without columns and girders. In this structure, logs or rectangular and hexagonal wood are stacked in parallel on the upper floor, and the two ends of the wood cross at the corner to form four walls of the house, which are like wooden fences on ancient wells, and then short columns are erected on the left and right walls to form the house. Hanging beam is a wooden structure, with a column and a beam on it. There is a short column and a beam on the beam. Mostly used in the north, the space is large and flexible.

Cross-bucket type is to string columns and squares together, which makes gables have strong wind resistance, but the space is small, so it is mostly used in the south. Ancient buildings in China used wood, brick and tile as the main building materials, and wood frame structure as the main structural mode. This structural mode is composed of columns, beams, purlins and other main components, and the joints between the components are equipped with tenons and mortises to form an elastic frame. There are three different structural modes of ancient wooden frame in China: hanging beam, span bucket and shaft. The hanging beam type is called "hanging beam type" because the beam is placed on the column and hung on the beam. This structure is often used in buildings, mansions and other large buildings. The bucket-piercing type is called bucket-piercing type because rows of columns are connected through purlins to form bent frames, and then connected through purlins. Mostly used in houses and smaller buildings.
