Prefabricated cabin top cover frame, prefabricated cabin top cover and prefabricated cabin

Abstract

The utility model relates to the field of switchgear room, concretely points to prefabricated cabin top cover frame, prefabricated cabin top cover and prefabricated cabin. Prefabricated cabin top cover frame includes the outer frame that is surrounded by the connection of horizontal section steel and longitudinal section steel, and one group of opposite two ends is connected with two end support beams for supporting the top cover plate among the opposite two ends in horizontal section or longitudinal section, and the middle support beam for the auxiliary support top cover plate is equipped between two end support beams, and the both ends of middle support beam are connected in another group of opposite two ends, and the top height of middle support beam is not higher than the top height of end support beam and not lower than the height of outer frame. Through the outer frame surrounded by section steel, the overall strength of top cover frame is improved, and the support beam is connected on the outer frame to form the top cover frame that can reliably support the top cover plate, the height of top cover is compressed while the strength is improved, and then the purpose that the net space utilization of prefabricated cabin is improved is reached. Prefabricated cabin top cover and prefabricated cabin all include prefabricated cabin top cover frame.
