Abstract
The utility model relates to a kind of highway noise shielding plate, annular shock-absorbing pad is provided with in pockets, annular shock-absorbing pad is in the bottom notch shape structure to pockets, the edge running through opening overturns toward the outer side and forms kinky-like structure, between annular shock-absorbing pad and pockets, be equipped with annular foam pad, one_to_one corresponding in the position of sound chamber pore, be provided with shock-absorbing cavity in yielding rubber layer.The utility model is on the basis of composite construction adopting traditional material, increase the assembly with sound-shock absorption function, effectively can absorb the impact of sound wave, annular foam pad coordinates special kinky-like structure more can improve the ability of absorption simultaneously, shock-absorbing cavity in simultaneous buffering rubber layer can absorbing vibration further, and overall structure can absorb sound in many places.
Description
Technical field
The utility model relates to a kind of highway noise shielding plate.
Background technology
In known technical field, along with socioeconomic development, the construction of road engineering is also maked rapid progress, although bring great convenience to the trip of people, but thing followed noise pollution is also day by day serious, especially on the route of highway, because car speed is higher, the noise pollution produced with windage is also more serious, inconvenience is brought to the people living in highway both sides, affect the comfortableness of its life, therefore general needs arranges in the both sides of road the shielding that sheet material carries out sound, the general namely foam of individual layer or the composite of plastic material, the poor effect of its insulating noise.
Utility model content
The technical problems to be solved in the utility model is: overcome the problems referred to above, provides a kind of highway noise shielding plate that significantly can improve noise isolation performance.
The utility model solves the technical scheme that its technical problem adopts: a kind of highway noise shielding plate, there is the aluminium alloy gripper shoe arranged in turn from outside to inside, yielding rubber layer and polyurethane foaming layer, the pockets that several cross sections are semicircular arc is evenly provided with at the inner surface of described polyurethane foaming layer, annular shock-absorbing pad is provided with in described pockets, described annular shock-absorbing pad is in the bottom notch shape structure to pockets, the center of described annular shock-absorbing pad is provided with runs through opening, the described edge running through opening overturns toward the outer side and forms kinky-like structure, annular foam pad is equipped with between described annular shock-absorbing pad and pockets, one_to_one corresponding is in the position running through opening, described polyurethane foaming layer is provided with sound chamber pore, one_to_one corresponding is in the position of sound chamber pore, shock-absorbing cavity is provided with in described yielding rubber layer.
Further, as a kind of concrete embodiment, described in the utility model, annular shock-absorbing pad is adhesively fixed in pockets.
Further, as a kind of concrete version, the layer of yielding rubber described in the utility model has the protruding block be embedded in the pore of sound chamber.
Further, as a kind of concrete version, the cavity of shock-absorbing described in the utility model is oval ball structure.
The beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, on the basis of composite construction adopting traditional material, increase the assembly with sound-shock absorption function, by being embedded in the annular shock-absorbing pad in polyurethane foaming layer, effectively can absorb the impact of sound wave, annular foam pad coordinates special kinky-like structure more can improve the ability of absorption simultaneously, unnecessary sonic impinging will be passed to through sound chamber pore and be positioned at middle yielding rubber layer, shock-absorbing cavity in simultaneous buffering rubber layer can absorbing vibration further, overall structure can absorb sound in many places, can not the veneer structure of similar traditional integrated setting when the sound frequency is too high, easily cause resonance, reduce the effect of noise reduction on the contrary.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the close-up schematic view at A place in Fig. 1;
In figure: 1. aluminium alloy gripper shoe, 2. yielding rubber layer, 21. shock-absorbing cavity, 3. polyurethane foaming layers, 31. sound chamber pores, 4. pockets, 5. annular shock-absorbing pad, 51. run through opening, 52. kinky-like structure, 6. annular foam pad.
