Description

Technical Field

[0001] The present invention relates to the technical field of temporary buildings, and in particular to a foldable house and a folding method. Background Art

[0002] Foldable houses have efficient space utilization and strong mobility. They have the advantages of quick construction, low cost, strong adaptability and high safety. They have been widely used at present and are particularly suitable for temporary resettlement in disaster areas after natural disasters such as earthquakes and typhoons.

[0003] New foldable mobile homes are widely used as mobile disaster relief housing, post-disaster resettlement housing, residential resettlement housing, field construction office housing, mobile residences, military field training housing, and mobile hotels. Compared with prefabricated housing such as container homes and color-coated steel homes, these new foldable mobile homes offer advantages such as quick construction, durability, comfort, mobility, and environmental friendliness.

[0004] Existing foldable houses have the following problems: First, the method of transporting parts to the construction site for assembly involves many complicated steps, such as sorting, docking, and fixing parts, which greatly reduces installation efficiency and consumes a lot of manpower and time. Second, after assembly, the foldable house is transported to the construction site for direct installation. Due to its large size and irregular shape after assembly, the requirements for transportation vehicles and routes are very demanding, making transportation extremely inconvenient. Third, the interior space of the house is small after expansion, and the folding and unfolding ratio is not high, which makes it difficult to meet the needs of multiple people living, limiting the application scenarios.

[0005] In view of this, it is necessary to provide a foldable house and a folding method to at least partially solve the above technical problems. Summary of the Invention
