Abstract

The invention discloses a modularized floor of a passenger train. The modularized floor of the passenger train is provided with a floor module, wherein the left side and the right side of a honeycombcomposite board of the floor module separately extend out of a sound-insulation and heat-insulation board to form a connecting portion of the floor module; a main floor is composed of a plurality of I-shaped floor modules, side section bars are separately arranged on the left side and the right side of each I-shaped floor module, a lower connector groove is formed in the lower portion of the innerside surface of each side section bar, the side section bars are clamped on the connecting portions of the I-shaped floor modules through the lower connector grooves and then are connected with the I-shaped floor modules, the inner side surface of the upper portion of each lower connector groove is arc-shaped, and floor cloth extends towards two sides and covers the arc-shaped inner side surfacesof the side section bars; and at least one of the front end and the rear end of each I-shaped floor module is provided with insertion section bars, the insertion section bars are embedded in the honeycomb composite board, and are divided into fork-shaped insertion head section bars and U-shaped insertion seat section bars, and the adjacent I-shaped floor modules are connected by inserting the fork-shaped insertion head section bars into the U-shaped insertion seat section bars which are matched with the fork-shaped insertion head section bars. The modularized floor of the passenger train is simple in connection structure and firm in strength, tools are not required during assembling of the modularized floor, and the modularized floor is quite convenient to assemble.
