Abstract
The utility model discloses a bottom sound leakage prevention device of a sound barrier. The bottom sound leakage prevention device comprises a convex metal supporting shell, wherein a sound absorption shell is embedded right below the convex part of the supporting shell; the height of the sound absorption shell is the same as the height of a convex top surface, and the length and the width of the sound absorption shell are also the same as those of the convex top surface respectively. The bottom sound leakage prevention device has the beneficial effects that all the supporting shell, the sound absorption shell and a cavity formed between the sound absorption shell and the supporting shell can achieve sound absorption and isolation effects of different degrees, and the noise which passes through a gap can be effectively reduced, an exposed bolt of a sound barrier stand column can be covered by the supporting shell, so that a flat mounting surface is provided for an upper sound barrier plate, the sealing is better, meanwhile, a protection effect on the bolt can be achieved, and the sound barrier has a neat and uniform appearance.
Description
Technical field
The utility model relates to the sound barrier technical field, particularly a kind of sound barrier bottom leakproof acoustic device.
Background technology
Traditional sound barrier bottom mainly contains two kinds of connected modes, and a kind of is directly to contact with surface of base, occurs the slit like this between sound barrier panel and base foundation easily and causes leakage sound; Another kind is because the interference of column bottom bolt forms a bigger slit between sound barrier panel and the base foundation.The conventional process mode is to be fixed on sound barrier panel at slit place with metal sheet or the basis is covered, but can't realize sealing between metal sheet and basis and the sound barrier panel, the very big leakage sound slit of same existence; Simultaneously, the metal sheet that covers usefulness comes off easily.
The utility model content
Goal of the invention of the present utility model is: at the problem of above-mentioned existence, a kind of sound barrier leakproof acoustic device is provided, be installed between bottom sound barrier panel and the concrete foundation, be mainly used in guaranteeing the bottom sound barrier panel can't contacting the noise leakage that causes with concrete foundation because erection bolt is interfered.
The technical solution adopted in the utility model is such: a kind of sound barrier bottom leakproof acoustic device, comprise convex shape metallic support housing, inlay under the part of this support housing projection the sound absorption shell is set, the height of described sound absorption shell is identical with the height of protruding end face, and also the length and width with protruding end face are identical respectively for length and width.Form cavity between sound absorption shell both sides and the support housing, this cavity has increased the low frequency defening effect.
As preferably, on described sound absorption shell one side panel honeycomb hole is set.
As preferably, the inner filling sucting sound material of described sound absorption shell.
As preferably, the no base plate in described support housing bottom.In actual use, can determine have base plate still not have base plate according to base state.
In sum, owing to adopted technique scheme, the beneficial effects of the utility model are: 1, support housing, sound absorption shell and sound absorption material all can play sound absorption effect in various degree, can effectively reduce the noise that sees through from the slit; 2, the support housing bolt shade that the sound barrier column can be exposed for the top sound barrier panel provides smooth installed surface, makes that sealing is better, can play a protective role to bolt simultaneously, also makes the sound barrier outward appearance neatly unified; 3, the honeycomb hole on the sound absorption shell can further be strengthened the sound absorption effect.
Description of drawings
Fig. 1 is cross-sectional view of the present utility model.
Mark among the figure: 1 is support housing, and 2 are the sound absorption shell, and 3 is sound absorption material, and 4 is honeycomb hole.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed explanation.
Most preferred embodiment: as shown in Figure 1, a kind of sound barrier bottom leakproof acoustic device comprises convex shape metallic support housing 1, inlays under the part of this support housing 1 projection sound absorption shell 2 is set, and support housing 1 bottom does not have base plate.
The height of described sound absorption shell 2 is identical with the height of protruding end face, and also the length and width with protruding end face are identical respectively for length and width.Form cavity between sound absorption shell 2 both sides and the support housing 1, this cavity has increased the low frequency defening effect.On described sound absorption shell 2 one side panels honeycomb hole 4 is set, sound absorption shell 2 inner filling sucting sound materials.
The utility model is overall structure in the longitudinal direction, and two ends are stretched into for the H shaped steel column that sound barrier is installed inboard and fixing, and whole device is easy, need not perforate on base foundation or top sound barrier, does not also exist owing to connect the loosening problem that comes off of causing.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
