Problems solved by technology

In this regard, the substructure supporting its rails to keep the distance between the rails is complex and the work efficiency during construction is low. When excessive impact is added to the rails, the durability is weak and loud noises are generated.

Embodiment Construction

[0023] The composite expansion joint according to the present invention is located between the first superstructure and the second superstructure of the bridge oppositely arranged at intervals, allowing the expansion and contraction of the two superstructures and supporting the wheels passing between the two superstructures. An expansion joint for a bridge passing smoothly between two superstructures, including first pin members arranged on the edge of the first superstructure and alternately forming pins (fingers) and pin slots toward the second superstructure, the first The pin member is fixedly supported on the first pin support member of the first superstructure, and the second pin member is provided opposite to the first pin member on the edge of the second superstructure and alternately forms pins and pin grooves toward the first superstructure. , to fix and support the second pin member on the second pin support member of the second upper structure, between the first pin...

Abstract

The invention relates a bridge extension connector, comprising a first pin component arranged on the edge of a first top structure to alternatively form pins and pin grooves to a second top structure, a first pin supporting piece for fixedly supporting the first pin component on the first top structure, a second pin component opposite to the first one, a second pin supporting piece, a third pin component alternatively formed between the first and second pin components, a middle rail arranged between the first and second supporting pieces, a middle rail supporting piece arranged at the first and second top structures, supporting the middle rail, and allowing the extension of the first and second top structures, and a rail space keeper.

Description

technical field [0001] The present invention relates to a bridge expansion joint arranged between an elevated highway or a bridge superstructure and the superstructure, in particular to a composite expansion joint (Complex expansion joint). Background technique [0002] Generally, the superstructure of a bridge expands or contracts due to temperature changes or the like. In this regard, when constructing a bridge, an appropriate spacing (commonly referred to as "a gap") is placed between two adjacent superstructures. An expansion joint is provided between such superstructures and superstructures. [0003] Expansion joints for bridges are broadly classified into rail type expansion joints and finger type expansion joints. [0004] Rail type expansion joints can be used on bridges with large expansion and contraction by increasing the number of intermediate rails according to the increase in expansion and contraction of the bridge superstructure with 80mm as the maximum spac...
