MAIN GIRDER FOR BRIDGE, BRIDGE HAVING SAME MAIN GIRDER, AND BRIDGE CONSTRUCTION METHOD
PROBLEM TO BE SOLVED: To provide a main girder for a bridge that can be easily assembled.SOLUTION: A main girder 1 is comprised of a plurality of a BH steel 2 connected in the longer direction. Each of the BH steel 2 comprises a projecting part 21a provided on a tip area of a web 21 which protrudes towards the BH steel 2 on a mating side and overlaps the web 21 on the mating side. Each of the projecting part 21a is provided with a mutually overlapping round hole 21b. A cylinder-shaped fastening pin 21c is inserted in each of the overlapping round hole 21b to connect both BH steel 2 to form the main girder 1 of a bridge.SELECTED DRAWING: Figure 1
【課題】簡単に組み立てることができる橋梁の主桁を提供することを課題とする。【解決手段】複数のＢＨ鋼２が長手方向に接続された主桁１であって、夫々のＢＨ鋼２は、相手側のＢＨ鋼２に突出し相手側のウェブ２１と重なる突出部２１ａをウェブ２１の先端領域に有し、夫々の該突出部２１ａには互いに重なる１個の丸孔２１ｂが設けられており、重なった夫々の該丸孔２１ｂに円柱状の固定ピン２１ｃが挿入されて両ＢＨ鋼２が接続されことを特徴とする橋梁の主桁１である。【選択図】図１
