Frame structure cabinet type

1 Core structure: Main framework: The columns and top/bottom frames are connected by box frame tenons, with the tenon head being 30mm long and the tenon socket being 35mm deep. They are bonded with redwood glue. Back panel: Embedded with an 8.5mm thick board, inserted into the frame groove (groove depth 10mm) with a threaded insert, and a 2mm expansion gap is reserved to cope with wood swelling. Door panel structure: Traditional jointed panel assembly: The outer frame is made of solid wood, the core board is 12mm thick, and the four sides are grooved and embedded in the door frame groove, allowing the core board to freely expand and contract. Hinge installation: Fixed with screws. 2. Mechanical properties: Resistance to deformation: The framework node failure load ?? 1800N (1.5 times that of the national standard GB/T 10357.4). Stability: The natural wood fiber direction is consistent with the stress, and the lateral stiffness is better than 3. Surface treatment: Wood wax oil penetration (3 coats) + beeswax polishing, retaining the wood’s breathing property.
