Embodiment 1
[0019] The present invention provides such Figure 1-2 A processing technology for a fire-resistant hot-dip galvanized polyurethane bridge, including the following steps:
[0020] S1: Fill polyurethane chemical raw materials into the inner cavity of the bridge base 1 made of hot-dip galvanized steel, and form the bridge base filling layer 2 by foaming the polyurethane chemical raw materials and bonding the inner cavity of the bridge base 1 at one time;
[0021] S2: Stamping and bending hot-dip galvanized steel sheets to form the inner lining 11 of the bridge base, filling polyurethane chemical raw materials in the gap between the inner lining 11 of the bridge base and the bridge base 1, and foaming the polyurethane chemical raw materials and the inner lining of the bridge base The gap between 11 and the bridge base 1 is bonded once to form a gap filling layer 17, and then the bridge base lining 11 is fixedly connected to the bridge base 1 by screws 12;
[0022] S3: The bridge...
