The invention provides a method for manufacturing a girder with a semicircular structure, the girder with the semicircular structure comprises an upper wing plate, semicircular partition plates and a web plate, the plane ends of the semicircular partition plates are connected with the upper wing plate, and the web plate is mounted on the arched outer surface of the semicircular partition plate, and the method comprises the following steps: placing the upper wing plate on a horizontal jig frame, and arranging a plurality of semicircular partition plates at intervals, the plane end of the semicircular partition plate is assembled on the upper wing plate; the web is divided into a left web, a right web and a middle web; the left web and the right web are hoisted to the two sides of the upper wing plate correspondingly, the plane ends of the left web and the right web are fixed to the upper wing plate correspondingly, and pressure is applied to the left web and the right web so that the left web and the right web can be bent and formed along the semi-arc partition plate and fixed; and after the middle web is hoisted above the upper wing plate to be fixed, the girder of the semi-arc structure is integrally welded, and the web covers the multiple semi-arc partition plates in the length direction. The method is simple in process, the construction cost is saved, and the construction economy is effectively improved.

    本发明提供一种半圆弧结构大梁的制作方法,半圆弧结构大梁包括上翼板、半圆弧隔板和腹板,半圆弧隔板的平面端与上翼板连接,腹板安装在半圆弧隔板的拱形的外表面,包括:将上翼板放置在水平胎架上,并将多个半圆弧隔板间隔排列,且半圆弧隔板的平面端装配至上翼板上;将腹板分成左腹板、右腹板和中间腹板;将左腹板和右腹板分别吊装至上翼板两侧,分别将左腹板和右腹板的平面端固定在上翼板上,对左腹板和右腹板进行施压,使左腹板和右腹板沿半圆弧隔板弯曲成型并进行固定;将中间腹板吊装至上翼板上方进行固定后对半圆弧结构大梁进行整体焊接,其中,腹板的长度方向覆盖多个半圆弧隔板。本方法工序简单,节约了施工成本,有效提升了施工的经济性。
