Abstract
The utility model relates to a motor car floor which is provided with a floor main body, wherein one side of the floor main body is provided with a tenon or groove; the floor main body is formed by bonding a first five-plywood board, a first rubber board, a second five-plywood board, a second rubber board and a third five-plywood board; the thickness of the floor main body is 19.0-20.0 mm, wherein the thickness of the rubber board is 1.95-2.05 mm; the five-plywood board is formed by alternately bonding birch sheets and cork sheets. The rubber boards of the floor main body have good sound insulation effect, and the cork sheets have the advantages of low specific gravity, light weight and good sound insulation effect, thus the motor car floor can achieve the effects of high sound insulation and light weight.
Description
Technical field
The utility model relates to bullet train floor.
Background technology
The high-speed cruising of motor-car, make the wheel and the rail bump of vehicle fierce more, noise that produces and vibrations are bigger, if there is not the floor of good soundproof effect, will certainly increase noise and vibrations in the compartment, reduce the speed-raising that dead weight of vehicle helps vehicle in addition, so more and more stricter to the requirement on the floor of high speed motor car.At present the floor of vehicle interior has and adopts wooden plywood's structure, also has to adopt the aluminium honeycomb core material, and its proportion is all bigger.
Summary of the invention
The purpose of this utility model is to propose a kind of high sound insulation and lightweight bullet train floor.
For achieving the above object, first technical scheme that the utility model is taked is as follows:
The utlity model has the floor main body, the both sides of floor main body are arranged with tenon or groove, the floor main body is formed by five-ply board, rubber plate, five-ply board, rubber plate and five-ply board gummed, the thickness of floor main body is 19.0～20.0 millimeters, wherein the thickness of rubber plate is 1.95～2.05 millimeters, and five-ply board is glued together at interval by birch thin plate and cork sheet and forms.
For achieving the above object, second technical scheme that the utility model is taked is as follows:
The utlity model has the floor main body, one side of floor main body is provided with tenon or groove, the floor main body is formed by seven plywood, rubber plate and seven plywood gummed, the thickness of floor main body is 19.0～20.0 millimeters, wherein the thickness of rubber plate is 1.95～2.05 millimeters, seven plywood are glued together at interval by birch thin plate and cork sheet and form, and the outermost birch gauge of sheet of two 7 plywood is 1.47～1.53 millimeters.
The utlity model has following good effect: floor of the present utility model main body is provided with at interval by five-ply board or seven plywood and rubber plate and forms, wherein rubber plate has good soundproof effect, five-ply board or seven plywood adopt to be glued together at interval by birch thin plate and cork sheet and form, cork sheet has the advantage that proportion is little, quality is light and sound insulation is good, so this bullet train floor can reach high sound insulation and lightweight effect.
