Wide-bodied pedestrian overpass erected among buildings

Abstract

The invention relates to a wide-bodied pedestrian overpass erected among buildings, which is characterized in that a double-column pier is arranged between the buildings at both sides of a road and the road; the bottom part of the double-column pier is connected with a bored pile foundation assorted with the double-column pier; the top part of the pier is provided with a bent cap; the main bridge of the wide-bodied pedestrian overpass is arranged on the upper surface of the bent cap; cantilevers at both ends of the main bridge are respectively and fixedly connected with the buildings; the main bridge mainly comprises a through steel truss, a bottom sealing steel plate and a deck pavement; the steel truss is formed by connecting upper chord members, lower chord members, web members with steel cross bars; the bottom sealing steel plate is fixed on the lower surfaces of the steel cross bars; and the deck pavement is arranged above the steel cross bars. The wide-bodied pedestrian overpass erected among the buildings has the characteristics as follows: the modeling conception is novel; the design is particular; the service function and the sightseeing function are integrated; higher additional loads can be borne; the designed deck width is large; the stress condition is brighter and clearer; the workload of the design calculation can be greatly reduced; and simultaneously, the construction is convenient, and the influence of the construction process on traffic is less.

Description

technical field [0001] The invention relates to a wide-body pedestrian bridge erected between buildings, which is widely used for connecting and passing between buildings. It belongs to the technical field of pedestrian bridge construction. Background technique [0002] Pedestrian bridges are also known as pedestrian overpasses. It is generally built in areas with large traffic volume and dense pedestrians, or on intersections, squares and railways. Pedestrian bridges only allow pedestrians to pass, and are used to avoid conflicts when the planes of traffic and pedestrians intersect, ensure people's safe crossing, increase vehicle speed, and reduce traffic accidents. [0003] In the prior art, common overpasses can be divided into three categories, namely suspended structures, supporting structures and hybrid structures. 1. The overpass with a suspended structure uses the bridge railing as the main load-bearing component. The bridge deck for pedestrians to pass through is...

Problems solved by technology

[0004] The purpose of the present invention is to solve the shortcomings of the pedestrian bridge in the prior art that it cannot be connected with the surrounding buildings, the width of the bridge deck is small, the structure is stressed, and the design workload is large, and to provide a pedestrian bridge erected between buildings. wide body pedestrian bridge,
