Description

Modular roof structure for rail vehicles technical field The invention belongs to the technical field of rail vehicles, and more specifically, relates to a modular roof structure for rail vehicles. structure. Background technique The interior roof is the main component of the interior decoration of the rail vehicle, while the interior roof is other components in the vehicle (such as empty space). Air ducts, interior armrests, etc.) provide installation interfaces. At present, the middle roof structure of rail vehicles mostly adopts the secondary frame and middle roof. Structural form of plate split installation. The commonly used materials for the middle roof are aluminum plate, aluminum honeycomb, etc. The secondary skeleton is mostly assembled with aluminum profiles made. This kind of structure requires that the secondary frame, air-conditioning duct, middle roof and handrail must be installed separately. When installing, first The skeleton hanging code is co...
