Straddle type monorail steel-concrete combined track beam box type main beam assembling method
The invention discloses a straddle type monorail steel-concrete combined track beam box type girder assembling method, which relates to the technical field of track traffic, and comprises the following steps: S100, finishing girder assembly by adopting an upside-down mounting method; s200, assembling and welding a transverse connection head plate and a flat connection head plate on the main beam; S300, assembling a bottom plate; s400, assembling and welding of the box body are completed, and deformation of extending flanges of the top plate and the bottom plate is corrected; and S500, assembling and welding of the stable surface part are completed. According to the straddle type monorail steel-concrete combined track beam box type main beam assembling method provided by the invention, a reasonable assembling sequence and a reasonable assembling mode are adopted; through reasonable use of measures such as preset camber, use of a linear beam manufacturing jig frame, drawing of a main plate positioning line, flame correction of an inverted arch matched with a jack, and a splicing mode of a reference end first hole method and a non-reference end total assembling and drilling, the problems that the manufacturing precision of a beam body structure with the high linear requirement is high, and the linearity of a beam body is difficult to control are solved.
本发明公开了一种跨座式单轨钢‑混结合轨道梁箱型主梁组装方法，涉及轨道交通技术领域，包括步骤：S100、采用倒装法完成主梁的组装；S200、组装焊接主梁上的横联、平联接头板；S300、装配底板；S400、完成箱体组装焊接并对顶板和底板伸出翼缘变形进行矫正；S500、完成稳定面构件的组装焊接。本发明提出的跨座式单轨钢‑混结合轨道梁箱型主梁组装方法，通过采用合理的组装顺序和组装方式，通过预设拱度和线型制梁胎架的使用、主要板件定位线的绘制、反拱配合千斤顶的火焰矫正、“基准端先孔法+非基准端总拼配钻”的拼接方式等措施的合理使用，解决了制造线形要求较高的梁体结构制造精度、梁体线性难于控制的问题。
