Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of steel structure beam processing, and in particular relates to a curved rib beam processing and assembling construction technology. Background technique [0002] With the emergence of a large number of special-shaped buildings such as large spans and space torsion, steel structures have become a pioneer in replacing traditional reinforced concrete structures because of their light weight, high strength, industrial production, over 90% reusability, and good processability. Design choice. The modern steel structure system is becoming more and more complex and diverse, and the scale is also increasing. The complex steel structure formed by the combination of various structural systems has been widely used in modern buildings. [0003] Such as figure 2 The space curved rib beam steel structure shown, the overall appearance presents a radial center sunken rotary throw dome roof, the whole roof is composed of ...
