Problems solved by technology

[0002] There are currently many types of bridge structures built on rivers, roads, and cliffs for long-term traffic, but the general cost is high, a variety of materials are used, and the construction period is long
Especially in mountainous areas where transportation is inconvenient, the difficulty of transportation of building materials is particularly prominent, which increases the total cost of the bridge and lengthens the construction period

Embodiment Construction

[0016] Such as figure 1 As shown, the present invention includes anchor ingot 1, steel strand cable 2, air bag 3, inflation and voltage stabilization control system 4, bridge deck pavement structure layer 5, and is used for fixing steel strand cable, air bag, bridge deck pavement A connection structure in which the structural layers are integrated. Two anchors 1 are separately installed and fixed at both ends of the bridge span. The two ends of the steel strand cables 2 are fixedly connected to the anchor spindles 1. The pavement structure layer 5 is laid on the top of the airbag 3 , and the inflation and pressure stabilization control system 4 is connected to the airbag 3 . The body of the airbag 3 includes a weather-resistant layer, a helium-resistant layer, a load-bearing layer and a heat-sealing layer from the outside to the inside. The weather-resistant layer uses a tadlar layer (or aluminized layer), the helium-resistant layer uses a Mylar layer, and the load-bearing lay...

Abstract

The invention discloses a tensioned air bag structure composite bridge comprising anchors, a steel strand pull string, an air bag, an air inflation pressure-stabilizing control system, a bridge surface paving structural layer and a connecting structure. The connecting structure is used for fixing the steel strand pull string, the air bag and the bridge surface paving structural layer into a whole. The two anchors are stably fixed on the two ends of a bridge span correspondingly, the anchors are fixedly connected with the two ends of the steel strand pull string, and the air bag is arranged above the steel strand pull string. The bridge surface paving structural layer is paved on the air bag, and the air inflation pressure-stabilizing control system is connected with the air bag. According to the tensioned air bag structure composite bridge, the good tensile performance achieved by combining the air bag manufactured from high performance fabric composite materials with the steel strand pull string is adequately used, so that the load requirement of crowds and vehicles on small and medium bridges is met, and less pressure surge in the air bag is guaranteed by the air inflation pressure-stabilizing control system, so that continuous tensile stress is provided. The tensioned air bag structure composite bridge is simple in structure and portable to transport, overall material using is less, the construction period is greatly shortened, and overall cost is remarkably reduced.

Description

technical field [0001] The invention relates to the field of bridge structures, in particular to a cable capsule structure composite bridge applied to low-load bridges in mountainous areas and landscape bridges in scenic spots. Background technique [0002] There are currently many types of bridge structures built on rivers, roads, and cliffs for long-term traffic, but the general cost is high, the materials used are various, and the construction period is long. Especially in mountainous areas where transportation is inconvenient, the difficulty of transportation of building materials is particularly prominent, which increases the total cost of the bridge and lengthens the construction period. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a cable capsule structure composite bridge, which is a new structural bridge with less material consumption, short construction period and low total cost. [0004] The presen...
