Subway station semi-prefabricated steel fiber concrete rail top air duct structure and construction method
The invention discloses a subway station semi-prefabricated steel fiber concrete rail top air duct structure and a construction method, the subway station semi-prefabricated steel fiber concrete rail top air duct structure comprises a beam plate, and the beam plate is provided with a notch along the length direction; the air duct assembly comprises at least two semi-prefabricated units formed by steel fiber reinforced concrete structures, the at least two semi-prefabricated units are arranged in the notches of the beam plate in an assembling mode, and the at least two semi-prefabricated units are matched and spliced with each other in the assembling mode to form a cavity of the rectangular air duct; a pouring inner cavity is formed between the at least two semi-prefabricated units and at the splicing position of the at least two semi-prefabricated units and the notch, and the at least two semi-prefabricated units and the beam plate are integrally formed by pouring steel fiber concrete to form the rail top air duct. Compared with a traditional post-cast concrete rail top air duct or an assembly type rail top air duct, the rail top air duct can be constructed together with a station beam plate at the same time, the construction period is short, the complex node connecting step in the installation process is avoided, and later maintenance is simple.
本发明公开了一种地铁车站半预制钢纤维混凝土轨顶风道结构及施工方法，包括：梁板，所述梁板沿其长度方向开设有缺口；以及风道组件，所述风道组件包括由钢纤维混凝土结构形成的至少两个半预制单元，至少两个半预制单元以装配方式设置在梁板的缺口内，至少两个半预制单元之间以装配方式相互配合拼接成为矩形风道的腔体；至少两个半预制单元间以及至少两个半预制单元与缺口拼接处设置为浇注内腔，至少两个半预制单元与梁板之间通过浇注钢纤维混凝土为一体形成所述轨顶风道。与传统的后浇混凝土轨顶风道或装配式轨顶风道相比，本发明的轨顶风道可以与车站梁板同时施工，施工周期短，避免了安装过程中节点复杂的连接步骤，后期维护简单。
