Abstract
A kind of aluminium foil pocket type metallic sound barrier, comprise keel, head plate, described head plate front is fixed with panel by self-plugging rivet, the head plate back side is fixed with backboard by self-plugging rivet, be welded with several keel by certain spacing inside backboard, the other end of keel is fixed with perforated plate by self-plugging rivet; Be provided with aluminium foil bag between described panel and perforated plate, in aluminium foil bag, be filled with sound absorption material.The utility model sound absorbing capabilities is good, and screen external body increases self-cleaning function, by after contamination by dust, still self-cleaning as being newly convenient to maintenance after natural rain wash; After aluminium foil bag is dust-full, can be loaded on after removing cleaning, still can keep original acoustically effective, increase application life.
Description
Technical field
The utility model relates to speedway, high-speed railway noise-reducing components, refers more particularly to a kind of aluminium foil pocket type metallic sound barrier.
Background technology
Along with the progress of society and the propelling of modern industrialization process, the noise that noise pollution has formed the healthy another killer's plant equipment of harm humans is the environment pollution be even more important in city, and the event that the various random noises as occurred when speedway, high-speed railway, urban elevated road, track traffic and source pump are runed disturb residents emerges in an endless stream.For this reason, researchers try hard to reduce the infringement of noise to the mankind in all its bearings, and take and arrange the measures such as sound barrier in road both sides.The structure that traditional sound barrier adopts usually is all insert sound absorption material after perforation, but is in round-the-clock rugged environment due to sound barrier, and is close to the main line of communication, and after long-term work, dust can have a strong impact on the performance of sound absorption material.Because sound barrier exists this type of deficiency, result in defening effect and do not reach actual demand application life, so be badly in need of improving prior art.
Summary of the invention
The purpose of this utility model solves above-mentioned Problems existing.
The utility model is achieved in that a kind of aluminium foil pocket type metallic sound barrier, comprise keel, head plate, it is characterized in that: described head plate front is fixed with panel by self-plugging rivet, the head plate back side is fixed with backboard by self-plugging rivet, be welded with several keel by certain spacing inside backboard, the other end of keel is fixed with perforated plate by self-plugging rivet; Be provided with aluminium foil bag between described panel and perforated plate, in aluminium foil bag, be filled with sound absorption material.
Backboard described in the utility model is in " C " shape, and the end face of backboard is set to isosceles trapezoid jut, and backboard bottom surface is set to isosceles trapezoid depressed part.
The size of isosceles trapezoid jut described in the utility model is less than the size of isosceles trapezoid depressed part.
The material that panel described in the utility model adopts is 1.3mm ultramicropore clad aluminium, and surface is evenly equipped with some through holes, and pitch-row is 2.2mm, and equivalent pitch-row is 0.1-0.25mm, and porosity is 1.1%-3.5%, through-hole rate more than 95%.
The material that perforated plate described in the utility model adopts is 0.6mm perforation galvanized sheet, and approximate aperture is 2mm, and perforated percentage is 13%.
The shape of keel described in the utility model, head plate is " C " shape and the material adopted is 1.2mm galvanized steel plain sheet.
The material that backboard described in the utility model adopts is 1.2mm galvanized sheet.
The utility model sound absorbing capabilities is good, and screen external body increases self-cleaning function, by after contamination by dust, still self-cleaning as being newly convenient to maintenance after natural rain wash; After aluminium foil bag is dust-full, can be loaded on after removing cleaning, still can keep original acoustically effective, increase application life.
