The invention is realized by the following technical scheme:
A connecting device for connecting two different specification assembled highway steel bridge truss pieces, includes: the steel plate comprises two channel steels, a steel plate, four connecting plates and four rib plates;
The bottom surfaces of the two channel steels are opposite and fixedly connected into a whole through more than two steel plates; a gap is reserved between the bottom surfaces of the two channel steels;
The four connecting plates are respectively arranged in a gap between the bottom surfaces of the two channel steels through the four rib plates, wherein the two connecting plates extend out along one side of the channel steels, and the distance between the two connecting plates on the side is the same as the size of a truss sheet of an assembled highway steel bridge with one specification; the other two connecting plates extend out along the other side of the channel steel, and the distance between the two connecting plates on the side is the same as the size of the truss sheet of the assembled highway steel bridge with another different specification;
pin holes used for being connected with truss pieces of the fabricated highway steel bridge are machined in the four connecting plates; the truss pieces of the two fabricated highway steel bridges with different specifications are respectively connected with the connecting plates on the two sides of the channel steel through the matching of the truss pins and the pin holes, so that the butt joint of the truss pieces of the two fabricated highway steel bridges with different specifications is realized.
further, four connecting plates are male plates.
Furthermore, four connecting plates are all female plates.
furthermore, the two connecting plates on one side of the channel steel are male plates, and the two connecting plates on the other side of the channel steel are female plates.
furthermore, the distance between the two connecting plates positioned on the same side of the channel steel is adjustable.
Has the advantages that: the distance between the connecting plates on the two sides of the channel steel is changed, so that the assembled highway steel bridge truss pieces with different specifications can be connected, the installation is convenient, and the efficiency is high; after the old bridge and the new bridge with different specifications are connected, the old bridge to be dismantled can be pushed as the guide beam of the new bridge (the guide beam does not need to be reinstalled for the new bridge), and the new bridge can be erected in place simultaneously when the old bridge is pushed out.
