BRIDGE SUPERSTRUCTURE
To provide a bridge upper structure which is less likely to cause damage or breakage due to collision with another member even in an end region of a bridge, and facilitating replacement or repair of a member such as a bearing in the end region of the bridge.SOLUTION: A superstructure 10 of a bridge 80, comprises a plurality of main girders 12, a cross-beam structure 14 comprising a metal box cross-section member having a first web 14A, a second web 14B opposed to the first web 14A, and an upper flange 14C and a lower flange 14D, one end part of a plurality of main girders 12 are respectively connected to a first web 14A of a horizontal beam structure 14, a support 84 arranged in a lower structure 82 of a bridge 80 is connected to a lower flange 14D of the horizontal beam structure 14, and a metal having a tensile strength of 400 N/mm2 or more is used as the outermost layer of the second web 14B of the horizontal beam structure 14 and the lower flange 14D of the horizontal beam structure 14.SELECTED DRAWING: Figure 2
【課題】橋梁の端部領域であっても他の部材との衝突による損傷や破損が生じにくく、また、橋梁の端部領域における支承等の部材の交換や修復がしやすい橋梁上部構造を提供する。【解決手段】橋梁８０の上部構造１０であって、複数の主桁１２と、第１のウェブ１４Ａおよび該第１のウェブ１４Ａに対向する第２のウェブ１４Ｂならびに上フランジ１４Ｃおよび下フランジ１４Ｄを有してなる金属製の箱断面部材で構成された横梁構造１４と、を有し、横梁構造１４の第１のウェブ１４Ａに複数の主桁１２の一端部がそれぞれ連結され、横梁構造１４の下フランジ１４Ｄに、橋梁８０の下部構造８２に配置された支承８４が連結されており、横梁構造１４の第２のウェブ１４Ｂおよび横梁構造１４の下フランジ１４Ｄには、引張強度が４００Ｎ／ｍｍ2以上の金属が最外層に用いられている。【選択図】図２
