Abstract
The utility model discloses a suspended air bridge. The suspended air bridge comprises a first air flue and a second air flue, wherein the second air flue is arranged above the first air flue and is vertically crossed with the first air flue. The left side and the right side of the first air flue are respectively provided with a bearing wall making tight contact with a bottom plate of the second air flue. The left side and the right side of the second air flue are respectively provided with a wind break wall. The two ends of each wind break wall are arranged on the upper side of the corresponding bearing wall in a crossing mode. A top plate of the first air flue is the bottom plate of the second air flue. Reinforcement beams are arranged in the top plate of the first air flue. The two ends of each reinforcement beam are arranged on the upper sides of the corresponding bearing walls in a crossing mode. The bearing walls can reinforce the connecting structure of the crossing position of the first air flue and the second air flue and prevent the position where the first air flue and the second air flue are vertically crossed from deforming, cracking and even collapsing. The wing break walls can avoid air leakage, caused by shaking, of the position where the first air flue and the second air flue are vertically crossed. Through the reinforcement beams, prestress can be generated in the top plate of the first air flue, and the connecting strength of the position where the first air flue and the second air flue are vertically crossed is enhanced. The suspended air bridge is simple in structure and convenient to construct, and has the advantages of being high in firmness, free of deformation, low in maintenance cost and high in safety coefficient.
