Assembled prefabricated assembled reverse sling and arch combined foot bridge and construction method thereof
The invention discloses an assembled prefabricated assembled reverse sling and arch combined pedestrian bridge and a construction method thereof, belongs to the field of bridge engineering, and solvesthe problems that an existing pedestrian bridge is inconvenient to transport and difficult to construct. The combined pedestrian bridge comprises two slings, two arch ribs, a plurality of hanging rods, a plurality of prefabricated bridge decks and two arch seats, wherein the two arch seats are located at the two ends of the bridge respectively, the two slings are arranged in parallel, the two arch ribs are arranged in parallel, the arch ribs are located above the slings, the slings and the two ends of the arch ribs are connected with the two arch seats respectively, the hanging rods are vertically and evenly distributed and connected between the slings and the arch ribs, the bridge decks are continuously distributed and installed on the slings, and the arch ribs are segmentally prefabricated. The construction method comprises the following steps: prefabricating the arch ribs and the bridge decks ; mounting the arch seats, splicing the arch ribs and cross braces, mounting the slings, and anchoring the arch ribs and the slings on the arch seats; mounting the bridge decks and the hanging rods; and mounting protective net handrails. According to the invention, a reverse suspension bridge is used as a basic principle, cables and arches form a self-balancing system, and the bridge is light, simple in stress, convenient to transport and simple in construction.
本发明公开了一种装配式预制拼装反吊索与拱组合人行桥及其施工方法，属于桥梁工程领域，解决了现有人行桥不便运输、施工困难的问题。本发明包括两根吊索、两片拱肋、多根吊杆、多块预制桥面板和两个拱座，两个拱座分别位于桥梁两端，两根吊索平行设置，两片拱肋平行设置，拱肋位于吊索上方，吊索和拱肋两端分别与两个拱座相连，多根吊杆竖向均布连接在吊索和拱肋之间，多块桥面板连续排布安装在吊索上，拱肋为分节预制。施工方法：预制拱肋和桥面板；安装拱座，拼接拱肋和横撑，安装吊索，拱肋和吊索锚固在拱座上；安装桥面板和吊杆；安装防护网栏杆。本发明以反吊桥为基本原理，索、拱形成自平衡体系，桥梁轻盈、受力简洁，便于运输，施工简单。
