Problems solved by technology

It is less comfortable to use and its applicability is reduced
The steel main girder and stairway girder have a large amount of engineering and poor economic efficiency; the steel box girder is a closed section, the space inside the box is small, and the steel structure is inconvenient to process. At the same time, the closed section form brings inconvenience to later maintenance and repair. The durability of its steel structure should not be guaranteed

Abstract

The invention discloses a steel plate girder pedestrian overbridge. The steel plate girder pedestrian overbridge comprises a bridge and ladder ways arranged at the two ends of the bridge; the bridge is of a through type structure of open type longitudinal and cross beams formed by splicing and welding I-shaped steel; the longitudinal and cross beams are fixedly connected to form a main ladder-shaped beam; two I-shaped steel beams formed by welding steel boards are adopted as stress longitudinal beams; the two longitudinal beams are connected through multiple small I-shaped steel cross beams; a profiled steel sheet concrete combined bridge panel is laid on the cross beams and used for transmitting live loads of bridge surface crowds. The steel plate girder pedestrian overbridge has the advantages of being simple in structure, reasonable in stress, easy to build, comfortable to use, small in work amount, low in manufacturing cost, economical, convenient to maintain, attractive in modeling and the like.

Description

technical field [0001] The invention relates to a pedestrian overpass, in particular to a steel plate girder pedestrian bridge with a steel plate girder as the main girder. Background technique [0002] The construction volume of urban pedestrian overpasses is huge, which requires simple structure, fast construction, good landscape and low cost. Due to its high rigidity and mature construction technology, steel box girder structure is the most commonly used main girder structure of overpass at this stage. And there is "National Building Standard Design Atlas. Urban Roads - Pedestrian Bridge" for design and construction. The steel box girder relies on a closed box section with a certain section height to support its own weight and crowd load, which belongs to the top-supported structure. The long-span steel box girder flyover has a relatively high cross-sectional height. Under the specified clearance requirements for vehicles under the bridge, the elevation of the bridge de...
