AI Technical Summary
Technical Problem
The existing I-shaped steel supports of small steel bridges lack support during welding, causing the supports to sway and affecting the welding quality.
Method used
A welded steel bridge frame base frame including a support mechanism and a limiting mechanism was designed. The fixing mechanism stabilizes the steel frame through the cooperation of threaded rods and threaded blocks, and the rubber pads fit tightly against the steel base frame. The limiting mechanism prevents the steel frame from shifting.
Benefits of technology
This ensured the steel frame remained stable during welding, improved welding quality and precision, and prevented external factors from affecting it.
