Bamboo rod system structure pedestrian arch bridge

Abstract

The invention relates to a bamboo rod system structure pedestrian arch bridge which comprises a bridge pier, a bamboo arch ring, a bamboo bridge panel, a bamboo bridge panel support and a bamboo handrail, wherein the bamboo arch ring comprises at least three parallel bamboo arch ring wattles, connecting element bolts and a bamboo connecting system beam; the heads and the tails of the bamboo arch ring wattles are connected by bolts, and the middles are also connected by bolts; the bamboo connecting system beam penetrates through clearances among the end parts of all the bamboo arch ring wattles and connects all the independent bamboo arch rings together; the bamboo arch ring is fixedly connected with the bridge pier by a steel connecting element; the bamboo bridge panel support is fixed tothe side surface of the bamboo arch ring; a vertical rod of the bamboo handrail and an outside guard board of the arch ring are fixed to the arch ring by bolts; and the bamboo bridge panel is fixed to the bamboo bridge panel support. The bamboo rod system structure pedestrian arch bridge of the invention has light self weight and small horizontal thrust and has the characteristics of low carbon, environmental friendliness, material saving, high processing speed of members, high construction and installation speed, and the like.

Description

technical field [0001] The invention relates to an arch bridge, in particular to a pedestrian arch bridge with bamboo bar system structure. Background technique [0002] An arch bridge is a common form of bridge. In long-span bridges, steel and / or reinforced concrete are generally used as bridge construction materials. However, as a pedestrian bridge or landscape bridge with a small span, wood can be used as a bridge building material. In pedestrian arch bridges, arched girders or simply supported beams are generally used as force-bearing members, and some stone arches are used as force-bearing systems. Stone arches are widely used in some areas with rich stone materials. However, due to the heavy stone materials, the processing and construction of arch bridge stone materials are also difficult, so the construction speed is slow, and heavy machinery and equipment are often used during construction. higher. If steel is used to build a pedestrian arch bridge, it is necessa...
