Three-crankcase steel connecting bridge and manufacturing method thereof

Abstract

The invention discloses a three-crankcase steel connecting bridge. The bridge consists of a top plate, a bottom plate, longitudinal web plates, a longitudinal stiffening plate, a transverse partition plate, an end cladding plate and bridge pier supports; the longitudinal web plates are fixed on the bottom plate, and the longitudinal stiffening plate is parallel to the longitudinal web plates and arranged between the longitudinal web plates; the transverse partition plate is arranged between the longitudinal web plates; the bridge pier supports are arranged at two ends of the bottom plate; and the top plate is covered on the longitudinal web plates and the longitudinal stiffening plate. The invention also discloses a manufacturing method of the three-crankcase steel connecting bridge. The three-crankcase steel connecting bridge has skilful structural design, unique shape, novel structure and smooth line type, and is light and attractive. According to the manufacturing method, a zone integrated assembly method is adopted in manufacture, and the integrated assembly is replaced by circular assembly, so the manufacturing quality is ensured, smooth field installation is ensured, and the field installation progress requirement can also be met.

Description

technical field [0001] The invention relates to a large-scale steel bridge, in particular to a three-curved box-shaped steel connecting bridge with large distortion, small internal space and complex structure and a manufacturing method thereof. Background technique [0002] Phoenix International Media Center is located in Chaoyang Park, Beijing. It is a media experience cabin with a new concept. It surpasses the previous relationship between the media and the audience through the screen, and introduces the audience into the open Mobius ring space to experience the charm of Phoenix Media. The steel structure of Phoenix International Media Center is a super-long-span space structure with a length of about 130m and a width of about 124m. The steel structure canopy is composed of two-way cross double full-beam structure and vertical support system, with a surface area of ​​about 27,500 square meters and a weight of about 5,200 tons. It is divided into inner and outer layers. ...

AI Technical Summary

Problems solved by technology

[0013] The steel connecting bridge is divided into several small sections. If the overall pre-assembly is adopted, the assembly time will be longer due to the high arch height and the erection of the assembled tire frame. How to ensure that each section of the steel connecting bridge achieves the effect of overall pre-assembly Without affecting the construction period of on-site installation, the pre-assembly solution is the third difficulty
