Abstract
The invention relates to a track sound-absorbing plate for a railroad bed. The track sound-absorbing plate for the railroad bed comprises a hollow support framework, wherein a sound-absorbing plate body is arranged in the support framework; one surface of the sound-absorbing plate body clings to the front panel of the support framework and the other surface of the sound-absorbing plate body is tightly pressed by an iron wire framework; through holes are formed in the front panel of the support framework. The track sound-absorbing plate is long in service life, and the sound-absorbing effect is the optimal. The sound-absorbing plate does not need to be replaced often, so that the track sound-absorbing plate has the highest cost-effectiveness.
Description
Technical field
The present invention relates to a kind of railway bed track sound absorption slipper.
Background technology
Acoustical board becomes the indispensable necessary equipment of railway periphery.Can be used for absorbing the noise produced in train vibration influence process, prevent from causing unnecessary impact to surrounding resident.But current acoustical board is short for application life, often will change, greatly reduce result of use, some places having little time to change can produce influence of noise to surrounding environment for a long time.
Summary of the invention
According to above deficiency of the prior art, the technical problem to be solved in the present invention is: provide a kind of and can overcome above-mentioned defect long service life, railway bed track sound absorption slipper that acoustically effective is good.
Railway bed track sound absorption slipper provided by the present invention, comprises support frame, and support frame is hollow structure, in support frame, acoustical board is set, acoustical board one side is close to the front panel of support frame, and another side is compressed by wired frame, and the front panel of support frame has through hole.Wired frame compresses acoustical board, does not in use have the problem of acoustical board tenesmus, ensure that physical life.
Described through hole for clap multiple row more.Through hole makes transmission sound efficiency greatly improve, and the working effect of acoustical board also gets a promotion.
Described through hole is strip.The through hole of strip ensures acoustical board and extraneous contact area to greatest extent.
The two ends of described wired frame are inserted in support frame.
Described support frame is silicon-magnesium-polymer.Silicon-magnesium-polymer belongs to light material, and has certain acoustically effective, compares the material being suitable as an overfill protection acoustical board.
Polypropylene layer is accompanied between described acoustical board and front panel.Because acoustical board is by through hole and extraneous contact, air, moist impact can be subject to unavoidably, be played a good protection by polypropylene layer, also can not affect acoustically effective.
The thickness of described support frame is 10-15cm.This thickness of acoustical board for railway bed track both sides has best economic benefit, and cost and effect all control in desirable level.
The beneficial effect that the present invention has is: long service life, and acoustically effective is the most desirable.Do not need frequent replacing, and cost performance is the highest.

Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention are described further:
Railway bed track sound absorption slipper as shown in Figure 1, comprises support frame 6, and support frame 6 is hollow structure, acoustical board 3 is set in support frame 6, acoustical board 3 one side is close to the front panel 1 of support frame 6, and another side is compressed by wired frame 4, the front panel of support frame 4 has through hole 2.Wired frame 4 compresses acoustical board 3, does not in use have the problem that acoustical board 3 drops, ensure that physical life.Through hole 2 for clap multiple row more.Through hole 2 makes transmission sound efficiency greatly improve, and the working effect of acoustical board 3 also gets a promotion.Through hole 3 is strip.The through hole of strip ensures acoustical board and extraneous contact area to greatest extent.The two ends of wired frame 4 are inserted in support frame 6, and fixed effect is better.Support frame 6 is silicon-magnesium-polymer.Silicon-magnesium-polymer belongs to light material, and has certain acoustically effective, compares the material being suitable as an overfill protection acoustical board.
Polypropylene layer 5 is accompanied between described acoustical board 3 and front panel 1.Because acoustical board 3 is by through hole 2 and extraneous contact, air, moist impact can be subject to unavoidably, be played a good protection by polypropylene layer 5, also can not affect acoustically effective.
The thickness of described support frame 6 is 14cm.This thickness of acoustical board for railway bed track both sides has best economic benefit, and cost and effect all control in desirable level.
