The invention discloses a curved ribbed beam
processing and assembling construction process. A processed curved ribbed beam is a curved steel beam, the cross-section of the curved steel beam is in the shape of a Chinese character ri, an outer side beam body and an inner side beam body of the curved ribbed beam are connected with each other through straining beams, and each of the outer side beam body and the inner side beam body is spliced by a number M of steel beam sections, each steel beam section comprises a top
flange plate, a bottom
flange plate, two webs and a vertical stiffening plate, and each steel beam section is provided with a connecting base. The curved ribbed beam
processing and assembling construction process comprises steps of (1)
processing the steel beam sections in a factory,
cutting steel plates, carrying out bending processing to the
steel plates, carrying out measuring and scribing processes, assembling the webs and the vertical stiffening plate, assembling diaphragm plates, laying
flange plate positioning mechanisms, assembling the flange plates and assembling the connecting bases; and (2) assembling the curved ribbed beam, determining the splicing positions of the steel beam sections, and splicing the steel beam sections. The curved ribbed beam processing and assembling construction process has simple steps, and is reasonable in design, convenient to implement and good in usage effect, and the processing and assembling construction process of the curved ribbed beam steel structure can be completed simply and quickly in high quality.
