[0002] In emergency rescue and disaster relief, there is an urgent need for emergency bridges erected quickly by hand. At present, prefabricated highway steel bridges are mostly used as emergency bridges. The weight of each main component is between 270 and 430 kg, and the number of people carrying a single piece needs to be 12 to 16. people; a single-lane 51-meter-fabricated highway steel bridge has a total weight of about 90 tons. Manual erection requires a lot of people, takes a long time to erect, and the bridge is difficult to push, which does not meet the requirements for emergency bridges for emergency rescue and disaster relief.

Embodiment Construction
[0024] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0025] See attached figure 1 , an assembled aluminum alloy emergency bridge, which includes: chords 1, triangular trusses 2, beams 3, bridge decks 4, bridge supports 5, wind-resistant pull rods 6, latches 7 and connecting pipes 8;
[0026] The main structure of the chord 1 and the triangular truss 2, the beam 3, the bridge deck 4, the wind-resistant tie rod 6 and the connecting pipe 8 are all made of aluminum alloy;
[0027] The overall connection relationship is as follows: the bottoms of two or more triangular trusses 2 are connected through connecting pipes 8 and pins 7 to form a truss group. Between them, the wind-resistant pull rods 6 are intersected at the bottom of the adjacent beams 3, the bridge deck 4 is erected on the beams 3, and the bridge supports 5 are arranged at both ends of the truss group.
[0028] Below, the components that make up th...

The invention relates to the technical field of emergency rescue, in particular to a fabricated aluminum alloy emergency bridge. The fabricated aluminum alloy emergency bridge comprises chord members,triangular trusses, cross beams, bridge decks, bridge supports, wind-resistant stay rods, plug pins and connecting pipes. The chord members, main structures of the triangular trusses, the cross beams, the bridge decks, the wind-resistant stay rods and the connecting pipes are all made of aluminum alloy materials. The overall connecting relation is that the bottoms of the more than two triangulartrusses are connected with the plug pins into truss sets through the connecting pipes, and the two truss sets are arranged side by side; the chord members are mounted on the tops of the truss sets, and the cross beams are arranged between the two truss sets; the wind-resistant stay rods are arranged at the bottoms of the adjacent cross beams in a crossed mode; and the bridge decks are erected on the cross beams, and the bridge supports are arranged at the two ends of the truss sets. The emergency response speed is increased greatly, the first-aid repair efficiency is improved greatly, and thefabricated aluminum alloy emergency bridge is well applied in engineering rescue practice.
