The core manufacturing process of the weld-free assembled LED display steel frame involves the processing of six modular components, enabling efficient on-site assembly.
1. Upper and Lower Frame Processing
The raw material uses fixed-length "C"-shaped steel. Before leaving the factory, it is cut into sections according to the number of horizontal modules, with any remaining sections marked. Each frame section is extended through fixing holes, and the surface is laser-cut with evenly spaced lifting lugs and weakening lines. During installation, the lifting lugs are folded 90° along the weakening lines and connected to the keel using pre-pressed rivet nuts.
2. Corner Fitting Processing
Corner fittings are transported using the same type of "C"-shaped steel, with lifting lugs and weakening lines cut simultaneously. On-site bending of the lifting lugs forms connecting fulcrums, providing the function of connecting and fixing the horizontal and vertical structures.
3. Left and Right Frame Processing
Although the process details are not clearly defined, as column components, they need to match the module spacing of the upper and lower frames. It is speculated that the processing method is similar to that of the upper and lower frames, achieving rapid assembly through standardized interfaces.
4. Keel and Cross Bracing Design
The keel, as the main load-bearing component, connects with the upper and lower frame lifting lugs to form a stress network. Cross bracing further reinforces the overall structure. Both are assembled using bolts or snap-fit connections, avoiding welding.
5. Full-Screen Installation Strategy
All prefabricated components are horizontally connected via folding lifting lugs and tightening bolts. Vertical structures rely on corner brackets for right-angle positioning. Modular assembly significantly reduces transportation losses and on-site construction time.
This system utilizes three key technologies: precise positioning with weakened lines, pre-installed rivet nuts, and laser cutting. This allows for 90% pre-processing of components in the factory, with only 10% requiring on-site bending to complete the entire screen assembly.
