Abstract
The utility model provides a floor structure with a high sound insulating capability. The floor structure with a high sound insulating capability is characterized in that a polyurethane sound insulating material is added in an internal chamber of a floor aluminum profile; a sound insulating pad is arranged in the floor; and a carpet is laid on the floor. According to the floor structure with a high sound insulating effect, the polyurethane is added in the floor aluminum profile to improve the intermediate-high-frequency sound insulating capability of the floor; and the sound insulating pad improves the intermediate frequency sound insulation factor of the floor; and the carpet is capable of reducing the reverberant sound in a car.
Description
Technical field
The utility model is applicable to the trolley coach floor panel structure.
Background technology
Internal car noise mainly is made up of airborne noise, structural vibration noise, reverberant sound during high speed train operation at present.Produce very big noise and vibration during the high speed train operation, and along with the noise and vibration that increases of speed also increases thereupon, it is very obvious that each frequency range airborne noise increases the order of magnitude, thereby control air sound becomes anxious problem to be solved.
The utility model content
The utility model technical matters to be solved is the suitable trolley coach floor panel structure of design, satisfies the floor and has high noise insulation factor needs.
For solving the problems of the technologies described above, the utility model provides a kind of high soundproof floor structure, it is characterized in that: floor aluminium section bar inner chamber is added with the polyurethane sound deadener, and sound insulating pad is set in the floor, and the top, floor is equipped with carpet.
The utility model increases floor medium high frequency sound-insulation capability through adding polyurethane in the aluminium section bar of floor; Sound insulating pad increases floor intermediate frequency noise insulation factor; Carpet reduces reverberant sound in the car.
Description of drawings
Accompanying drawing is the structure section figure of the utility model.
The specific embodiment
With reference to accompanying drawing, aluminium section bar 2 inner chamber filled polyurethane sound deadeners 3 in floor are whenever filled full die cavity at a distance from 1 die cavity with polyurethane; Floor aluminium section bar upper and lower surfaces spraying damping slurry layer 1,4; The bonding wooden frame 10 in aluminium section bar top, floor; Lay drainboard 5 earlier between aluminium section bar top, floor and the wooden frame, lay winter protection material 6 then; Sound insulating pad 7 is bonding with wooden frame 10 again with wood covering 8 bonding composition integral body earlier; Wood covering 8 top laying floor cloth 9; Carpet 11 is laid in floor cloth 9 tops.
