Bridge support structure

Abstract

The invention discloses a bridge support structure, and relates to a support. The side wall of an upper frustum (7) is in contact with the inner wall of an upper taper hole (5); the upper end of an upper frustum (7) is positioned at the lower end of a circular groove A (4); a lower support (15) sleeves a lower frustum (12) through a lower taper hole (14), the inner wall of the lower taper hole (14) is contacted with the side wall of the lower frustum (12), the lower end of the lower frustum (12) is positioned at the upper end of a circular groove B (16), a gap (19) is formed between the uppersupport (6) and the lower support (15), and a connecting column (11) is arranged in the gap. The bridge support is arranged to be of the structure that a core block is embedded between the upper support and the lower support, and the purpose that a steel box girder can play a role in buffering no matter the steel box girder slightly twists or slightly deviates from the core block in the using process is achieved through the core block made of the rubber material and a spring set arranged in the core block.

Description

technical field [0001] The invention relates to a support, in particular to a bridge support structure. Background technique [0002] With the continuous expansion of the city scale and the increase of the number of cars, it has brought congestion on the main roads of urban traffic and main roads in different directions at the intersection of the plane, and the emergence of urban bridges such as viaducts and overpasses has enabled the traffic to be stratified , Three-dimensional intersection, dredging road traffic and improving traffic efficiency. As one of the superstructure types of bridges, steel box girders are becoming more and more important in urban bridge construction due to their advantages such as light weight, large span, beautiful line shape, and fast construction progress; as bridge superstructure and substructure The construction and installation process of bridge bearings with intermediate connectors has a great influence on the on-site construction of the br...

As one of the superstructure types of bridges, steel box girders are becoming more and more important in urban bridge construction due to their advantages such as light weight, large span, beautiful line shape, and fast construction progress; as bridge superstructure and substructure The construction and installation process of bridge bearings with intermediate connectors has a great influence on the on-site construction of the bridge, the use after opening to traffic, and the replacement of the bearing itself after reaching the end of its service life; the existing bridge bearings are generally only It can withstand the load in the vertical direction, and it cannot correct the displacement of the bridge
