Embodiment 1

[0029] See Figure 1 to Figure 10 , this embodiment is a conventional floor, with a main floor 1, the main floor 1 has several type I floor modules 11, and the type I floor modules 11 are composed of floor cloth a, honeycomb composite board b and sound insulation The heat insulation board c, wherein the sound insulation and heat insulation board c is provided with a grid-shaped metal support frame d, and the type I floor module is supported by the rubber part e which is under the metal support frame d and fixed on the vehicle frame. The honeycomb composite board b can be made of aluminum, and the sound and heat insulation board c can be made of glass wool felt 2, melamine foamed cotton or synthetic rubber foamed material. The above-mentioned structure makes the main floor have a good effect of shock absorption and noise reduction. The left and right sides of the honeycomb composite panel b of the type I floor module protrude from the sound and heat insulation panel c to form ...

Embodiment 2

[0035] See Figures 11 to 15 , this embodiment is a specific floor, with a main floor 1, the front end of the main floor 1 is connected with a front raised floor 3 through a transition module 15, the rear end is connected with a door entrance area floor 2, and the door entrance area floor 2 is connected with a rear raised floor floor 4. The front raised floor 3 leads to the driver's cab, and the rear raised floor leads to other passenger compartments.

[0036] The front raised floor 3 has two Type I floor modules 11, and the transition module 15 has the same composition as the Type I floor modules 11. The middle of the Type I floor module 11 connected to the transition module 15 has a step 11-1. The left and right sides of the transition module 15 are respectively provided with side profiles 6 , and the connection method between the side profiles 6 and the transition modules 15 is shown in the connection between the side profiles 6 and the Type I floor module 11 in Embodimen...

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.

Description

technical field [0001] The present invention relates to modular floors for railway passenger cars. Background technique [0002] The document of Chinese Patent Application No. 201811066265.6 discloses a modular floor for high-speed EMUs, which includes a support part arranged at the bottom of the car body, a shock-absorbing part on the support part and a floor body on the shock-absorbing part. The floor body can include Flooring and flooring cloth, the flooring can be a composite board consisting of two surface layers and a core material, the surface of which is coated with moisture-absorbing paint and bonded with an adhesive. Among them, the surface layer adopts birch and cork combined multi-layer laminated board, the thickness of each layer of board can be about 9.6mm, and a total of 7 layers of core board structure can be set up; the core material in the middle of the wooden floor adopts 0.2mm sound insulation layer. The floor cloth can use 3mm thick rubber sheet. The d...
