Technical field

The invention relates to the field of building structures, and in particular to a bamboo green prefabricated house and a construction method thereof.

Background technique

Prefabricated buildings refer to the construction of houses using systematic design, modular disassembly, factory manufacturing, and on-site assembly, that is, buildings assembled on the construction site using prefabricated components. The development of prefabricated buildings is a major change in construction methods and an important measure to promote supply-side structural reform and new urbanization development. It is conducive to saving resources and energy, reducing construction pollution, improving labor productivity and quality and safety levels, and is conducive to promoting construction Deeply integrate industry and informatization industrialization, cultivate new industries and new momentum, and promote the resolution of excess production capacity. In countries and regions such as the United States, Germany, Sweden, Denmark, Australia, and Singapore, the proportion of prefabricated buildings is relatively high. Among them, Germany is the country with the fastest development in residential assembly and building energy consumption reduction in the world, and the proportion of residential prefabricated components is as high as 94.5%. According to data released by the Ministry of Housing and Urban-Rural Development, prefabricated buildings currently account for less than 5% of new buildings in my country.

Bamboo is a natural renewable resource with excellent physical and mechanical properties and is easy to process. It is internationally recognized as a green building material. Its environmental consumption is much less than that of steel bars and cement, and it meets the requirements of green, low-carbon and sustainable development. For the same building area, using bamboo and wood structures instead of concrete structures can save 45% of energy during the construction phase and 50% to 70% during the use phase. At the same time, prefabricated bamboo and wood structures can be used not only in low-rise residences, but also in high-rise residences. In 2012, wooden (bamboo) structures were included in the "Beijing Green Building Applicable Technology Promotion Catalog", with the purpose of vigorously promoting the application of wooden engineering structural materials in the construction of small buildings within three floors. Modern bamboo prefabricated structure buildings are built using component factoryization and construction assembly. They are characterized by design standardization, component componentization, and construction mechanization. They can integrate multiple industrial chains of design, production, and construction, and implement the principles of resource conservation and construction. National policy to protect the environment.

Therefore, the research, development, promotion and application of assembly and connection technology for bamboo green prefabricated houses has great economic, social and ecological significance.
