-3～10
-4Doubly, when therefore only making the thickness of damping material more much bigger than rail web thickness, just can obtain effective loss factor values, can make damping layer too thick like this, both uneconomical, influence is used again.
Conclusion is got up, and uses damping material attached to there being following four major problem on the rail waist at present:
(1), the general damping material all makes base material with pitch class or rubber type of material, therefore has problem of aging, especially in the open, under Exposure to Sunlight and the severe cold, durability can not get assurance.
(2), there is poor, the easy problem such as spontaneous combustion of refractoriness in bituminous material or rubber type of material, therefore unfavorablely locate to use at subway etc.
(3), there is certain volatile noxious material in bituminous material, uses more improper in the airtight underground space.
(4), sound-absorbing effect is limited and price is high, is learnt by test, pastes the test specimen of six layers of pitch class damping material, noise reduction is still dissatisfied, the rubber type of material effect is poorer.
Summary of the invention
The utility model purpose is to provide a kind of excellent noise reduction effect, low, the easy production of cost, easily install take the rail sheath of sound absorption reduction measure from sound source itself.It not only can adopt when new rail is installed, and original rail can also be transformed easily.For realizing the object of the invention, the utility model has adopted following technical scheme: a kind of noise reduction cover that is used for track, go up by pillow that the cover socket forms between cover and pillow, cover is made up of skin plating, web of the rail sound-absorbing section on the pillow, web of the rail sound-absorbing section inner close fitting web of the rail place is provided with liner plate, is filled with damping material between liner plate and the skin plating; Cover is made up of interior wrapper sheet, intermediate layer and skin plating between pillow, and the intermediate layer is filled by damping material and formed, and the cover cavity shape is made identical with the lower semisection profile of track between pillow.
Described intermediate layer is made up of waist support section and flange of rail section, is lined with abatvoix in the waist support section, fills damping material in the flange of rail section.Glued joint skin plating top and below, track top flange.Be stained with vibration isolator outside the bottom of cover on the pillow.Described damping material is the numb suede of super glass wool or glass fiber, pitch glass wool, mineral wool.Abatvoix has 1～3, is covered with aperture on the abatvoix.Skin plating is made with sheet metal, and interior wrapper sheet is made with metal or nonmetal plate.Make with iron plate as skin plating, interior wrapper sheet is made with veneer.On interior wrapper sheet and liner plate, also can be provided with aperture.The profile of cover is less than cover between pillow on the pillow, by bonding agent will rest the head on be socketed between pillow overlap in.The length of overlapping between cover and pillow on the pillow is decided on the tie distance of track.This noise reduction cover can be gone up pillow to be enclosed between cover and pillow to assemble in the workshop and arrive on-the-spot the installation again.The cover compartment of terrain is socketed on the rail between also can at the scene pillow upward being overlapped and rest the head on.During use, can require on the full track road, to establish cover according to noise reduction, also can part, the part establishes cover.
