The invention relates to a mounting structure of a box-type rail top air duct, and each air duct unit is of an integrally prefabricated box-type structure and comprises an air duct top plate, an air duct bottom plate and two air duct side plates; assembly components are arranged on the air duct top plates, assembly holes are correspondingly reserved in the station middle plate, the assembly components penetrate through the assembly holes from bottom to top, the tops of the assembly components are limited and fixed to the station middle plate through limiting installation assemblies, and filleris poured into the assembly holes. The integrally-prefabricated box type structure is adopted, and the problems existing in cast-in-place rail top air duct construction can be avoided; the overall structural strength of the air duct unit is remarkably superior to that of a conventional U-shaped air duct unit; the box-shaped air duct units are good in annular sealing performance, and the air leakage phenomenon of the contact position of the prefabricated part and the middle plate can be avoided. Installation and fixation of the air duct unit are achieved through cooperation of the assembly component on the air duct top plate and the limiting installation assembly above the station middle plate, and operation is easy and fast.

    本发明涉及一种箱型轨顶风道的安装结构,各风道单元均为一体预制成型的箱型结构,包括风道顶板、风道底板及两块风道侧板;各风道顶板上均设有装配构件,车站中板上对应预留有装配孔,装配构件自下而上穿过装配孔并且其顶部被限位安装组件限位固定在车站中板上,于装配孔内浇筑有填充料。本发明采用一体预制的箱型结构,可避免现浇轨顶风道施工存在的问题;风道单元的整体结构强度显著地优于常规的U型风道单元;箱形的风道单元环向密闭性良好,能避免预制件与中板接触位置的漏风现象。通过风道顶板上的装配构件与车站中板上方的限位安装组件配合实现风道单元的安装固定,操作简单快捷。
