Abstract

The invention provides a cross-beam-free type dispersing deflexion expansion joint mechanism and relates to the field of telescopic devices for bridge main beams. The cross-beam-free type dispersing deflexion expansion joint mechanism comprises a deflexion assembly and a joint crossing assembly, the deflexion assembly comprises a first edge beam, a second edge beam, a middle beam, a connecting rodassembly, a guiding rail assembly, a middle beam sliding block, an edge beam sliding block and a sealing plate, and the first edge beam and the second edge beam are stored on the two sides of the middle beam correspondingly. The joint crossing assembly comprises outer hexagon bolts, an elastic support and a joint crossing plate, the deflexion assembly is located on a first bottom plate, and the connecting rod assembly, the guiding rail assembly, the edge beam sliding block and the middle beam sliding block are arranged on the lower portions of the first edge beam, the second edge beam and themiddle beam in the transverse bridge direction at intervals correspondingly. The joint crossing assembly is fixed to the first edge beam and a second bottom plate through the outer hexagon bolts andthe elastic support correspondingly. According to the cross-beam-free type dispersing deflexion expansion joint mechanism, the joint crossing function and the expansion-contraction function of an expansion joint are mutually independent, work is good, the structural service life is long, the safety and durability are high, assembled manufacturing and mounting can be facilitated through the structure, and the later-period maintenance condition is good.

Description

technical field [0001] The invention relates to the field of expansion devices for bridge girders, in particular to a beam-free dispersed displacement expansion joint mechanism. Background technique [0002] Expansion joints are one of the key structures on bridge girders. The main types are rubber expansion joints, steel expansion joints, modular steel expansion joints, comb-shaped expansion joints, seamless expansion joints, etc. [0003] Currently commonly used expansion joints are often dedicated to realizing multiple functions such as joint spanning, expansion and contraction, vertical rotation, plane rotation, and plane swing at the same time on an overall structure. Under this traditional thinking, the functions of expansion joints are mutually restricted, and the single function is greatly reduced. The structure is very complicated, and the components are fatigued and worn seriously. The expansion joints are frequently damaged and maintained frequently. Contents of...
