Round Bamboo Prefabricated House Manufacturing Technology
Round bamboo prefabricated house manufacturing technology mainly includes aspects such as solar round bamboo prefabricated houses, the manufacturing and connection of round bamboo pole structural components in prefabricated bamboo buildings, and the construction technology of large-span round bamboo arch structures.
Solar Round Bamboo Prefabricated Houses: Load-bearing components are made from processed round bamboo raw materials, with round bamboo support columns and bamboo panels used to create load-bearing and heat-conducting composite walls. Some or all of the round bamboo is made into heat-conducting components, and the composite walls of load-bearing components and enclosure materials are modularized and serialized for factory prefabrication. Holes are drilled through some or all of the round bamboo tubes in the load-bearing components and load-bearing and heat-conducting composite walls to form hot air passages from solar collectors. The joints of the load-bearing components are reinforced with metal connectors, and anti-crack hoops are added above and below the round bamboo joints to ensure structural stability.
Manufacturing and Connection of Round Bamboo Pole Structural Components in Prefabricated Bamboo Buildings: Load-bearing components of the house, such as beams, purlins, rafters, columns, and trusses, are all made from the poles of large bamboo species. The dimensions of each round bamboo pole in the components are increased, and this is achieved by binding and reinforcing two or more bamboo poles with 'metal hoop - bolt' connectors. Different forms of metal connectors are used to connect the round bamboo load-bearing components to each other, as well as to connect the round bamboo components to the enclosure structure cladding panels (walls, roof sheathing, etc.). The main structural components can be prefabricated in the factory. Round bamboo poles are selected from large bamboo species that are over 3 years old, with a length of over 7m, a lower-end diameter of 8-11cm, an upper-end diameter of 5-8cm, and free from cracks, decay, and insect damage. Metal connectors include 'regular figure-eight', 'irregular figure-eight', and 'U-shaped' metal hoops, as well as L-shaped metal connectors used between perpendicular planes.
Construction Technology of Large-Span Round Bamboo Arch Structures: Leveraging the characteristics of round bamboo being lightweight, high-strength, and easy to bend and shape, it is commonly used in large-span arch structures. The application of standard round bamboo materials extends the lifespan of round bamboo arch structures; component prefabrication reduces engineering difficulty and promotes the assembly process of bamboo buildings; clever joint construction and structural design, along with tie reinforcement, improve the safety of bamboo buildings; and post-construction health monitoring and safety maintenance further ensure the safety of large-span round bamboo arch buildings.
