Abstract
The utility model relates to a sound absorbing barrier board which is composed of a panel, a backboard and frames; wherein, the panel and the backboard are respectively fixed on the frames; and a sound absorbing material is positioned in the frames. The sound absorbing barrier board is characterized in that: trapezoid waves with uneven sections are pressed on the slabs of the panel and the backboard longitudinally, the panel is provided with sound absorbing holes, the bevel with upward trapezoid waves of the panel is a blind plate without hole. The utility model presses the panel and the backboard of the barrier board into uneven trapezoid waves so that the slabs seem to be provided with a plurality of strengthening ribs, thereby enhancing the strengthen by a large margin, effectively cutting down the material cost and lowering the weight of the entire barrier board. At the same time, the bevel with upward trapezoid waves of the panel is not provided with sound absorbing holes, therefore showing a waterproof protection effect. The utility model is broadly arranged at the two sides of roads, railways and city orbits for shielding noises.
Description
Technical field
The utility model relates to a kind of road and track traffic noise reducing apparatus, particularly about a kind of gobo baffle with wavy cross-section.
Background technology
Along with the progress of society, the development in city, people's living standard constantly improves, and urban traffic has become the most closely-related problem with us.Building up of a large amount of expressways, being open to traffic of urban light rail brings great convenience for our trip, but stays in the influence that near these expressways and the light rail resident is standing traffic noise simultaneously.In order to improve the civic dwelling environment, various gobo baffles have been installed by relevant department in the road both sides and around the light rail track.
Present gobo baffle operated by rotary motion panel and backboard, panel and backboard all adopt slabbed construction, open the sound absorption hole on the panel, between panel, the backboard skeleton are set, and porous absorption material is set between skeleton.Yet along with the more and more thinner development trend of panel, backboard sheet metal thickness, the intensity of gobo baffle also more and more causes designer's common concern.Solution to this problem generally be density and the intensity that increases skeleton, but this can increase the consumption of material significantly, and the weight of shield plates also can increase much thereupon.
Summary of the invention
At the problems referred to above, it is good that the purpose of this utility model provides a kind of structural strength, saves material, in light weight, the gobo baffle that acoustically effective is good.
For achieving the above object, the utility model is taked following technical scheme: a kind of gobo baffle, it is made up of panel, backboard and skeleton, described panel and backboard are separately fixed on the described skeleton, be provided with sound absorption material between the described skeleton, it is characterized in that: on described panel and the backboard sheet material, laterally be suppressed with the cross section and be concavo-convex trapezoidal wave, described panel is provided with the sound absorption hole, and the trapezoidal wave inclined-plane up of described panel is imperforate blind plate.
The utility model is owing to take above design, and it has the following advantages: 1, the utility model is owing to be pressed into the panel of shield plates and backboard and have concavo-convex trapezoidal wave, therefore makes on the sheet material as being provided with many reinforcing ribs, and its intensity is greatly strengthened.2, the utility model is owing to the intensity of having strengthened plate by trapezoidal wave, and therefore compared with prior art, the density of skeleton setting can reduce, and therefore can save material cost effectively, reduces the weight of whole shield plates.3, the utility model is not owing to be provided with the sound absorption hole on the trapezoidal wave inclined-plane up of panel, so rainwater can not enter sound absorption material by perforation.The utility model structural strength is good, saves material, and in light weight, acoustically effective is good, and it can extensively be arranged on the both sides of various highways, railway and city rail, in order to the shielding noise.

The specific embodiment
As shown in Figure 1, the utility model is made up of panel 1, backboard 2 and skeleton 3, and panel 1 and backboard 2 are separately fixed on the skeleton 3, can be provided with various sound absorption materials between the skeleton 3.On panel 1 and backboard 2 sheet materials, laterally be suppressed with the cross section and be concavo-convex trapezoidal wave 4, panel 1 is provided with sound absorption hole 5, but the sound absorption hole is not set on the trapezoidal wave inclined-plane 6 up of panel 1, is blind plate.
