Description

Technical Field

[0001] This invention belongs to the field of door technology, specifically relating to an installation structure for a reinforced steel frame metal glass door. Background Technology

[0002] Stainless steel glass doors boast a modern and stylish design, blending stainless steel sheets with specialty glass craftsmanship. Suitable for various commercial and office environments, they enhance overall aesthetics. Easy to clean and maintain, they retain their shine and beauty for a long time. Stainless steel is corrosion-resistant, heat-resistant, and its electrophoretic surface treatment prevents rusting and ensures a long service life. Custom-made frosted, embossed, and other artistic glass finishes are available to enhance the sense of spaciousness and decorative appeal.

[0003] Traditional stainless steel glass doors use wooden baseboards for the door frame, which have weak load-bearing capacity. Due to the heavy weight of stainless steel glass doors, the door frame is prone to loosening and deformation during later use, resulting in problems such as the stainless steel glass door not opening and closing smoothly, not closing tightly, and deteriorating aesthetics. The glass is embedded in the stainless steel frame during installation, making disassembly difficult and subsequent maintenance inconvenient. Summary of the Invention

[0004] To address the aforementioned problems in the existing technology, the present invention aims to provide a reinforced steel frame metal glass door installation structure. This structure employs a reinforced metal door frame design, with galvanized reinforcing plates installed at the structural connections and hinge points within the metal door frame. This prevents excessive load on the overall door frame and improves its load-bearing capacity, avoiding quality issues such as door frame deformation and loosening at structural connections. The metal door features a concealed hinge structure design, with the hinge hidden inside the metal door frame and fixed to a hinge fixing plate, resulting in a simple and aesthetically pleasing structure. Furthermore, the double-fixed glass structure design of the door leaf frame ensures more secure tempered glass installation, and the glass is removable for convenient maintenance.
