Antiskid structure of ancient bridge deck and construction transformation method
The invention discloses an anti-skid structure of an ancient bridge deck and a construction transformation method, and relates to the technical field of bridge repair. Comprising piers, a bridge, an original foundation on the upper side of the bridge, a lower-layer structure and an upper-layer structure, and the upper-layer structure is provided with a metal bridge surface and internally provided with a flowing cavity; the lower layer structure is provided with a lower frame and a flexible bag, a flexible bag pipeline is communicated into the flowing cavity of the bridge floor, and a phase change material is arranged in the flexible bag; and a heat-conducting fin, a plurality of mechanical roller assemblies for providing heat for the heat-conducting fin and a driving device are also arranged in the lower frame. As the ancient bridge is transformed on the basis of the ancient bridge, the bearing part is not directly arranged on the structure of the ancient bridge; the mechanical roller assembly in the lower layer structure can conduct heat to the flowing cavity in a rolling friction heat generation mode, and the phase-change materials in the flowing cavity are in a flowing state, so that it is guaranteed that the metal bridge deck cannot be frozen or frosted due to the too low environment temperature.
本发明公开了一种古桥桥面的防滑结构及施工改造方法，涉及桥梁修复技术领域，其技术方案要点是，技术效果是。包括桥墩和桥梁，桥梁的上侧的原基础、下层结构和上层结构，上层结构具有金属桥面，且内部具有流动空腔；下层结构具有下框架、柔性囊，柔性囊管道连通至桥面的流动空腔内，柔性囊内部设有相变材料；下框架内还设有导热片、提供导热片热量的多个机械辊组件和驱动装置。由于本发明在古桥基础上改造，将承重部分不直接设置在古桥本身结构上；下层结构内部的机械辊组件可以通过滚动摩擦生热的方式，将热量传导流动空腔，由流动空腔内的相变材料处于流动状态，确保金属桥面不会因为环境温度过低而结冰，无霜冻现象。
