By using the design, the damping vibration-isolation sound barrier has the advantages that firmness and durability are realized; the sound isolation quantity of a sound absorption component in a resonance region and an anastomosis effect region is improved; the sound barrier performance is improved.
Description
Technical field
The present invention relates to a kind of sound barrier, particularly a kind of damping isolation sound barrier.
Background technology
Along with the development of social progress and city, people's living standard constantly improves, and urban transportation has become as and our the most closely-related problem.Therefore, reduce the noise invasion to road both sides resident, become a vital task in the city-building of current China, building up of substantial amounts of expressway, being open to traffic of urban light rail and high-speed railway, bring great convenience to our trip, but stay in the resident near these expressways, light rail and high ferro simultaneously and suffer from the impact of traffic noise.In order to improve civic living environment, relevant department is mounted with various absorbent lined barrier around road both sides and light rail, high ferro etc. are along the line.
Present sound barrier is traditionally arranged to be steel column and Felt, the installation of steel column is generally left out the rigidity contact surface between column and body of wall and the rigidity contact surface between sound absorbing-insulating body and column, thus causing that the secondary of noise is propagated, on the other hand, the acoustic board of existing sound barrier is generally panel and becomes gobo body with composition of backboards, this panel, backboard pin-connected panel processing technology, in transport, carrying, installation process, surface rivet easily comes off, and the intensity of gobo body also increasingly causes the common concern of designer.Solution to this problem, is usually the density and intensity that increase skeleton, but this can increase the consumption of material significantly, and the weight shielding body plate also can increase much therewith.
Summary of the invention
Goal of the invention: it is an object of the invention to solve the present problem that sound barrier vibration resistance is weak, intensity is low.
Technical scheme: the present invention provides techniques below scheme: a kind of damping isolation sound barrier, including the sound barrier panel that polylith is arranged above and below, sound barrier panel both sides are provided with for clamping and the steel column of fixed sound shield plates, flat ethylene propylene diene rubber vibration isolator it is lined with bottom steel column, adhesive type ethylene-propylene-diene monomer rubber cushion is filled with sound barrier panel gap inside steel column, described sound barrier panel back side inwall is provided with vibration isolation damper assembly layer, in sound barrier panel, filling porous sound absorption damper assembly and the porous sound absorption damper assembly for wrapping up porous sound absorption damper assembly protect wrap film, multitube ethylene propylene diene rubber vibration isolator it is provided with bottom sound barrier panel, single tube ethylene-propylene-diene monomer rubber cushion it is provided with between adjacent sound barrier panel, every piece of sound barrier panel is equipped with at least one shock-absorbing spring.
As optimization, flush with sound barrier panel bottom bottom described steel column.
As optimization, described shock-absorbing spring one end props up porous sound absorption damper assembly protection wrap film, and one end props up sound barrier panel inwall.
As optimization, described vibration isolation damper assembly layer thickness is 3~5 times of sound barrier panel thickness of shell.
Beneficial effect: the present invention is relative to prior art:
1, flat ethylene propylene diene rubber vibration isolator it is lined with bottom steel column, fill adhesive type ethylene-propylene-diene monomer rubber cushion with sound barrier panel gap inside steel column, adopt this kind of design, simple in construction, improve the vibration resistance of steel column above-below direction, be also improve its intensity from another point of view.
2, adopt vibration isolation damper assembly layer thickness to be sound barrier panel thickness of shell 3~5 times, to improve the sound absorption component oise insulation factor at resonance region and coincidence effect district, improve its sound insulation property.
3, every piece of sound barrier panel is equipped with at least one shock-absorbing spring, improves the vibration resistance in steel column direction, is also prevent sound barrier panel chattering frequency too fast, it is therefore prevented that the noise that self produces.
