Abstract
The utility model relates to a sound absorption and insulation barrier. A concrete base is fixed with profile steel upright columns through bolts, sound absorption and insulation boards mainly made of magnesite materials are embedded into concave slots of the profile steel upright columns and are firmly pressed by spring compression sheets; and the sound absorption and insulation boards are distributed with a plurality of groups of sound absorption bar holes. The sound absorption and insulation barrier adopts the high-strength glass magnesium based light composite sound absorption and insulation board and the magnesite material, is filled with sound absorption materials such as glass rock wool and so on, has excellent acoustical property and durability, and has the advantages of water resistance, fire resistance, shock resistance, aging resistance, crack prevention, no radiation and so on. The sound absorption and insulation barrier is mainly used for sound barrier engineering of municipal traffic road networks such as railways, light rails, highways, urban elevated roads and so on.
Description
Technical field
The utility model relates to the pollution control technology field of noise, is specifically related to a kind of modular sound absorbing-insulating barrier, belongs to International Classification of Patents E01F8/00 technical field.
Background technology
At present, be used for the sound barrier that road noise administers and generally have two kinds: a kind of is the barrier made from metal sheet or non-metal board, and this barrier only plays the sound insulation effect, does not absorb acoustic energy.The sound insulation effect is relatively good for the noise reduction of high-frequency noise, and in the frequency band range of road traffic noise, it is many that the medium and low frequency noise accounts for, thereby noise reduction is unsatisfactory.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, and providing a kind of can absorb sound and insulate against sound, therefore the sound absorbing-insulating barrier with good noise reduction.
The purpose of this utility model is achieved through the following technical solutions.
A kind of sound absorbing-insulating barrier, be on concrete pedestal by bolt mount type steel post, be embedded in the installation Felt at the concave groove of shaped steel column, and compress by spring pressuring plate.This Felt is that main material is made with the magnesite material.
Be placed with many group sound absorption bar holes on the described Felt.
The utility model is the compound Felt of high-strength glass magnesium base lightweight, it adopts magnesite sill etc., pass through structure optimization design, filled sound absorption material glass rock wool etc., thereby have excellent acoustical behavior and durability, and have waterproof, fire prevention, shockproof, anti-aging, anti-be full of cracks, shock resistance, advantage such as radiationless.Be mainly used in the sound barrier engineering of traffic municipal administration road networks such as railway, light rail, speedway and urban elevated road.
Description of drawings
Fig. 1 is the side-looking structural representation of the utility model sound absorbing-insulating barrier;
The effect schematic diagram that Fig. 2 arranges for the positive sound absorption of the utility model sound absorbing-insulating barrier hole.
Among the figure: 1, shaped steel column, 2, Felt, 3, spring pressuring plate, 4, pedestal, 5, the sound absorption bar hole.
The specific embodiment
Referring to Fig. 1, Fig. 2, this sound absorbing-insulating barrier is the position that the sound absorption wall is installed at needs, at first uses concrete pouring pedestal 4, and according to sound barrier 2 length, reserves the bolt that is complementary with shaped steel column 1; After treating that pedestal 4 solidifies fully, shaped steel column 1 is installed on the position of reserving bolt, and fastening with nut; Between amphitypy steel post 1, Felt 2 is embedded respectively in the concave groove of shaped steel from down to up, and the back side compresses with the spring steel card, compress with spring pressuring plate 3 and get final product; Brush is colored at last coats with lacquer.
Sound absorbing-insulating barrier of the present utility model is the compound Felt of high-strength glass magnesium base lightweight, be to adopt the magnesite sill, fibrous material and modified component etc. are by the optimal design of structure and component, adopt advanced compression molding technology, after steam-cured initial set, carry out the processing of panel sound absorption bar hole, percent opening reaches about 15%, carry out the steam-cured design strength that reaches of secondary after the perforate, through surface spraying (chromatic waterproofing paint or spray outdoor lacquer, guarantee colour-fast) technological process preparation such as back filling sucting sound material glass rock wool have excellent acoustical behavior and a structural performance (containing durability), and has waterproof, fire prevention, shockproof, anti-aging, anti-be full of cracks, shock resistance, advantage such as radiationless is mainly used in railway, light rail, the sound barrier engineering of traffic such as speedway and urban elevated road municipal administration road network.
Detect through State Bureau of Building Materials Industry quality examination center, the compound Felt of high-strength glass magnesium base lightweight that the utility model is selected for use has good sound insulation property, its sound insulation 〉=43dB, the standard that is higher than country 〉=40dB, body of wall space, weight and cost have been saved greatly, shortened installation period simultaneously, be a kind of novel, energy-saving wall efficiently, add and fill sound-absorbing glass rock wool in the plate, its sound absorption effect is better, is the first-selected product of the sound barrier engineering of traffic municipal administration road networks such as railway, light rail, speedway and urban elevated road.The compound Felt combustibility of high-strength glass magnesium base lightweight, detecting through authoritative institutions such as national fire-proof construction material quality supervision and test centers is A level non-automatic incombustible material, fire endurance met the requirement of fire wall in the lightweight fully greater than 3 hours.The compound Felt humidity resistance of high-strength glass magnesium base lightweight is good, and immersion 7 is no change round the clock, and its dried green deformation rate, the dimensional contraction of being heated rate all are that other products is incomparable.The compound Felt of high-strength glass magnesium base lightweight is a kind of light weight board ,≤39.3kg/m
2, be convenient to construction.The compound Felt shock resistance of high-strength glass magnesium base lightweight is good, detects through national authority mechanism, and sandbag impacts still flawless 8 times, is higher than national sandbag far away and impacts 3 flawless standards.In addition, it is good that the compound Felt of the high-strength glass magnesium of ZA210-100 base lightweight also has a fold resistance, in the construction loss little, fritter can utilize again, is difficult for pulverizing, and can bore, and can saw, and can follow closely, and can dig, and decorates the characteristics of being easy to, and is subjected to users' favorable comment and dependence.
