[0002] The aluminum-clad wood door and window frame is a composite high-end door and window structure, which is composed of an outer aluminum alloy frame and an inner solid wood frame. The outer aluminum alloy has excellent weather resistance, water resistance and corrosion resistance, can resist wind and rain erosion and ultraviolet radiation, and ensures the stability of long-term outdoor use. The inner layer selects natural wood (such as pine, oak or jackwood), which is treated with corrosion and insect prevention, not only has the decorative beauty of natural texture, but also has excellent heat preservation and insulation performance, effectively reducing energy consumption. The two are tightly combined through hidden buckles or adhesive-mechanical composite connection technology, which not only solves the defects of easy aging of pure wood windows and fast cold and heat conduction of pure aluminum windows, but also is suitable for villas, high-end residences and historical building repair projects with high requirements for appearance and performance, and takes into account environmental protection, durability and visual elegance.

[0003] The prior art adopts a composite connection mode of buckles and direct thread fastening to improve the stability of the aluminum-wood structure. However, in actual situations, due to the significant difference in thermal expansion and contraction characteristics between aluminum and wood, the expansion and contraction ranges of aluminum and wood cannot be coordinated when affected by temperature changes, resulting in mutual pulling forces at the joint, which can cause sealing failure, reduced sound insulation and heat preservation performance, and significantly shortened overall service life of the door and window.
