Foot bridge of self-anchorage balance stress chord rope structure

Abstract

The invention discloses a foot bridge of a self-anchorage balance stress chord rope structure. The foot bridge of the self-anchorage balance stress chord rope structure comprises a bridge deck slab, eccentric structures, a horizontal tensioning chord rope, counter weight loads and longitudinal stay bars, wherein the bridge deck slab is arranged on the horizontal tensioning chord rope, the horizontal tensioning chord rope is connected with the eccentric structures on the two sides, the counter weight loads are arranged on the eccentric structures, the longitudinal stay bars are arranged between the eccentric structures and the horizontal tensioning chord rope, and rod pieces are arranged between the horizontal tensioning chord rope and the longitudinal stay bars. According to the foot bridge, the characteristics of using local materials in a mountainous area are brought into full play, by means of the existing geological and topographic conditions in the mountainous area, the external material transportation and construction installation difficulty is lowered, and the foot bridge not only is applicable to the mountainous area, but also can be used for an urban overpass, is safe in stress, convenient to construct, economical and practical, and has higher application and popularization value.

Description

technical field [0001] The invention belongs to the technical field of pedestrian bridges, and in particular relates to a pedestrian bridge with a self-anchored and balanced stressed string structure. Background technique [0002] When crossing rivers in mountainous areas, cable bridge structures are mostly used as simple structures at present. Due to the small rigidity of the cable bridge structure, the swaying is obvious under the pedestrian load. At the same time, the anchorage of the cables must be considered, and the construction is inconvenient. If the self-balancing lower cable upper arch structure is adopted to fold the tie-rod arch bridge structure, the cost cannot be popularized in impoverished mountainous areas because of its complicated fabrication and installation. Contents of the invention [0003] The purpose of the present invention is to provide a footbridge with a self-anchored balanced force string structure, which aims to solve the problem that when cro...

Problems solved by technology

[0003] The purpose of the present invention is to provide a footbridge with a self-anchored balanced force string structure, which aims to solve the problem that when crossing rivers in mountainous areas, the cable bridge structure is mostly used. The lower sway is obvious, and at the same time, the anchorage of the cables must be considered, and the construction is inconvenient. If a self-balancing lower-cable upper-arch structure and a tie-rod arch bridge structure are used, it cannot be popularized in poor mountainous areas due to its complicated production and installation and high cost. question
