Prefabricated Retractable Foldable Double-Wing Expansion Integrated House

The prefabricated retractable foldable double-wing expansion integrated house is based on retractable, foldable and modular expansion. It adopts high-strength galvanized steel frame and plug-in buckle structure. The box can be compressed to 1/3 of its original volume during transportation, which greatly reduces logistics costs. It can be hydraulically unfolded or manually unlocked on site, and a single box can be converted from a flat state to a functional space with a floor height of 2.8 meters in 30 minutes. Water and electricity are pre-installed and ready to use. The modular design supports unlimited expansion - horizontal splicing to form an open exhibition hall, vertical stacking to create a three-story loft apartment, or staggered combination to form a creative space to meet dynamic needs such as family expansion and shop upgrades. Its folding seams use military-grade sealing technology, earthquake resistance of 9 levels, wind resistance of 12 levels, A-level fire wall body fire resistance of more than 1 hour, and the indoor temperature difference in environments from -40℃ to 60℃ is only ±5℃. The box can be disassembled and reassembled without damage for more than 20 times, and is equipped with a folding photovoltaic roof and rainwater recovery system to achieve a low-carbon cycle. One person can complete the installation and expansion, from emergency tents, mobile offices to home sunrooms, and Internet celebrity pop-up stores. With the characteristics of "free extension and contraction, unlimited growth", it redefines flexible, efficient and sustainable space solutions.
