Abstract

The invention relates to a transition connection device for an aluminum alloy pedestrian bridge. The transition connection device comprises an inner vertical surface and an outer vertical surface, wherein the inner vertical surface is communicated with the outer vertical surface through a support frame; both the inner vertical surface and the outer vertical surface comprise upper chords, lower chords, vertical rods and oblique rods; the vertical rods and the oblique rods are used for connecting the upper chords and the lower chords together; the two ends of the lower chords are connected with connecting ends; a fixed support is arranged at the bottom of the connecting end on one side of each lower chord; a movable support is arranged at the bottom of the connecting end on the other side of each lower chord; joint points are set at the bottoms of the fixed support; and movable sliding chutes are formed at the bottoms of the movable supports. According to the transition connection device, the overall stress points of a bridge can be dispersed, concentrated stress points are reduced, meanwhile the bearing capacity and bearing area of a mouth-shaped aluminum alloy pedestrian bridge are increased, the stability of the mouth-shaped aluminum alloy pedestrian bridge is ensured, and the pedestrian bridge has the advantages of reasonable structure, high stability, high reliability, high durability and regular and practical overall effect.

Description

technical field [0001] The invention relates to a transition connection device, in particular to an aluminum alloy flyover transition connection device, and belongs to the technical field of manufacturing aluminum alloy flyover overall frame connection components. Background technique [0002] At present, the "口"-shaped aluminum alloy flyover adopts the form of lapped trusses between the main truss and the transition truss. Its main features increase the bearing capacity of the bridge, enhance the stability of the aluminum alloy flyover, and ensure the completion of the installation of the "口"-shaped aluminum alloy flyover. There is no shaking afterwards. However, the traditional transition truss has concentrated stress points, limited bearing capacity and bearing area, and the influence of weather changes may lead to unstable connection and easy wear, which reduces the service life and stability. Contents of the invention [0003] The technical problem to be solved by th...
