Abstract
The utility model relates to a garage entrance-exit low-noise slope which is formed by the method that a grizzly screen type ramp which is homodromous to a cement ramp is arranged on the cement ramp, and a sound-sucking cavity which is made of sound sucking materials or is composed of a sound-sucking structure is formed between the cement ramp and the grizzly screen type ramp. The grizzly screen type ramp of the utility model has larger frictional force than a sawtooth-shaped ramp, and the average sound-sucking coefficient of the sound-sucking cavity is larger than 0.9 so that the noise of the ramp can be reduced by more than 8dB and the noise of entrance and the exit of a garage can be reduced by more than 8 dB; thereby, the neighborhood of the entrance and the exit of a garage achieves the standard that a sanitary protection distance required by a sound environmental quality standard in a first class region or a second class region in 'urban regional environment noise standard ' is reduced by more than 4 meters, and simultaneously the grizzly screen type ramp also has the characteristics of water, dust, mud resistance, direct wash, etc.
Description
Technical field
The utility model relates to a kind of ramp, particularly the ramp of access, garage.
Background technology
In recent years, along with increasing rapidly of China's vehicle guaranteeding organic quantity, city parking contradiction becomes more and more outstanding.Because land resources is more rare in the city, adding that traditional Surface parking lots exists with the pedestrian conflict, influences many unfavorable factors such as view, reduction visibility, builds under the concentrated area, semi-underground garage parking is widely adopted as the main means of this contradiction of solution.Parking contradiction has solved, but access, relevant garage noise is more and more as the noise pollution complaint of dwelling house, office building etc. to closing on building, and the noise of reduction or control access, garage is a very urgent problem.
For reducing access, garage noise pollution, can only take at present top, access, garage that the measure of sound absorption ceiling, the sound absorption processing of two side, access is set both at home and abroad, but these measures can not fundamentally reduce access, garage noise, and there are many shortcomings, as the sound absorption ceiling is set can influences view on every side, influence closes on building bottom daylighting and ventilation, if adopt the light transmissive material structure, as PC plate, doubling glass, sunlight board etc., can produce the sound that falls into water when rainy and wait regenerated noise to pollute; Be provided with behind the ceiling because access noise directive property is stronger, and the localized positions noise has the increase phenomenon on the contrary the access, garage outside, this measure simultaneously is unfavorable for that also the access, garage locates the diffusion of vehicle exhaust; The sidewall sound absorption of access, garage is handled and also can be caused the effective clear span minimizing in access etc.
At home, zigzag cement ramp is generally adopted in access, underground at present, semi-underground garage, and this kind ramp not only noise is higher, and the sound absorption coefficient in ramp own is zero substantially, can not effectively reduce the ramp reflected sound.
Summary of the invention
The purpose of this utility model provides a kind of frictional force and sound absorption coefficient is all big and environmentally friendly low noise ramp at gate of carport.
The purpose of this utility model is achieved through the following technical solutions: comprise the cement ramp, on described cement ramp, be provided with one with its in the same way, the grid type ramp in sound absorption chamber is arranged therebetween.
Between described cement ramp and grid type ramp fixedly connected, arranged the damping vibration attenuation pad.Described grid type ramp is the ramp of laying the panel composition with hole seam.Described sound absorption chamber is that cavity and the sound absorption material arranged within it constitute, or cavity and the formation of sound absorption construction within it.The grid in described grid type ramp has mesh-structured, damping, stiffness and the radiating surface that effective inhibition self surface vibration produces regenerated noise.
The ramp noise comprises automobile tyre and fricative noise of access, garage ramp surface and ramp reflected sound.The utility model is to reduce tire and the fricative noise of ramp surface by optimizing pits rampway structure, adopt the sound absorption ramp to reduce the ramp surface reflected sound, for both are organically combined, the grid type ramp of cavity is divided in employing, lays porous material or resonant cavity, the microperforated absorbers etc. such as polyamine fat vacuole foam of waterproof and dustproof in the cavity.The grid type ramp is mesh-structured, leaves hole or seam above promptly, and wherein porosity requires can not influence incident substantially like this greater than 40%, certainly, considers grid intensity, and the grid porosity can not be excessive.Like this, incide on the ramp noise through grid propagate into the sound absorption chamber in after, by the sound absorption of sound absorption material in the chamber or sound absorption construction, its reflected sound energy is less than 10%.Grid type ramp surface frictional force is greater than zigzag cement ramp, and the adhesive power of tire increases greatly during the vehicle climb and fall, and the ramp noise but descends more than the 8dB.
The utility model is owing to adopted the grid type ramp, and it has bigger frictional force than zigzag cement ramp; Set sound absorption chamber, grid type ramp average sound absorption coefficient, totally can make more than access, the garage radiated noise decline 5dB more than the low 8dB of the comparable zigzag cement of ramp noise ramp noise greater than 0.9; The utility model can make the garage come in and go out both sides 50dB (2 class district standards for acoustic environmental quality at night in " standard of environmental noise of urban area "), 45dB (1 class district standard for acoustic environmental quality at night in " standard of environmental noise of urban area ") noise contours apart from garage center line average distance reduce 5m respectively, more than the 4m, promptly reach 1 class district or 2 class district standards for acoustic environmental quality equally, access, garage noise width of sanitary protection zone can reduce more than the 4m; Characteristics such as the grid type ramp also has waterproof and dustproof, anti-mud, can directly wash.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is wherein a kind of schematic diagram in grid type ramp;
Fig. 3 is the schematic diagram of vertical gusset of Fig. 2;
Fig. 4 is the schematic diagram of the horizontal gusset of Fig. 2.
The specific embodiment
With reference to Fig. 1, the utility model is that 10 pairs of support columns 3 are set on cement ramp 1, has arranged the damping vibration attenuation pad on support column 3 respectively, and is by bolt that grid type ramp 4 is fixing on the damping vibration attenuation pad.Dividing into the damping vibration attenuation pad in grid type ramp 4 is to produce regenerated noise for effectively suppressing the vibration under the driving vehicle excitation of grid type ramp 4.The driving frequency in ramp when the best vibration damping frequency of damping vibration attenuation pad is vehicle '.Between cement ramp 1 and grid type ramp 4, form a cavity, in cavity, arrange sound absorption material such as amine polyester foam composition sound absorption chamber 2, or microperforated absorber composition sound absorption chamber 2 is set in cavity.Grid type ramp 4 is intersected by vertical gusset 6 with big damping and horizontal gusset 5 to be formed, as shown in Figure 2.Vertically gusset 6 is fluted, as shown in Figure 3.Laterally gusset 5 has double wedge, as shown in Figure 4.Vertically the double wedge of the groove of gusset 6 and horizontal gusset 5 can be connected, through being welded to form grid type ramp 4.The also available panel construction with hole seam in grid type ramp 4 is laid and is constituted.4 upper ends, grid type ramp are connected with the road surface, and the lower end is connected with ground in the garage.
