CN203452015U - Transparent type acoustic shield - Google Patents

Abstract

The utility model discloses a transparent type acoustic shield which comprises H-shaped steel arranged on a bridge guardrail or an anti-collision wall, one or more transparent shield units are arranged between every two adjacent pieces of the H-shaped steel, and the portion, 200-500m away from the top, of the acoustic shield bends towards the inner side of the bridge guardrail or the anti-collision wall to form an arc top. The part between every two pieces of H-shaped steel is a unit, and the each unit is composed of one or more pieces of laminated glass. The position, 200-500m away from the top of the transparent type acoustic shield, is made to be arc, a part of diffraction sound is eliminated, sound insulation is increased, meanwhile, under the condition that the distance between a vehicle and the anti-collision wall is not changed, the inwards-bent arc top increases the incidence angle from the vehicle to the top, the distance between the vehicle and the shield is shortened, so that the height of a thrown object is increased, and the probability of the thrown object is reduced.

Description

A kind of open type noise barrier

Technical field

The utility model relates to a kind of noise barrier, specifically refers to a kind of open type noise barrier.

Background technology

Traffic noise is urban traffic in the process of the modernization future developments such as high-grade, high-speed, overhead solid, vehicles number sharply increase bring make the day by day serious noise pollution of urban highway traffic noise pollution.The reason that traffic noise pollution problem produces, mainly contain two aspects: the one, traffic above-ground facility has existed or existing planning, in its adjacent domain, build the noise-sensitive structures such as school, hospital, house, because programming and distribution are unreasonable,, there is traffic noise pollution problem after causing noise-sensitive structure to come into operation in reserved necessary antinoise distance; The 2nd, the pollution from environmental noise causing due to construction or the operation of traffic above-ground facility.Except newly-built traffic above-ground facility may produce pollution from environmental noise, after some traffic above-ground facilities put into operation, along with the increase of vehicle flowrate, or the change of operational factor (as railway speed increase), also may produce new problem of noise pollution.Road traffic noise has the advantages that intensity is large, influence basin is wide, becomes gradually the primary pollution source of urban environment noise, also becomes the difficult point that environmental noise is controlled.The development of noise barrier is exactly the impact for transport solution noise on human life and work, from source and the route of transmission of noise, control and abate the noise, noise barrier refers to as alleviating driving noise near resident impact is arranged on to the other wall formula structure of roadside.But current noise barrier exists that structure is single, weight is large, the problems such as inconvenient are installed, and phenomenon from foreign material to bridge outside that throw away occurs repeatedly, and caused certain safety problem.

Utility model content

The purpose of this utility model is to provide a kind of open type noise barrier, and what when playing sound barrier defening effect, also solve current bridge existence easily throws away to bridge outside the safety problem that foreign material cause, and reaches the probability that article are outwards thrown away in minimizing.The purpose of this utility model is achieved through the following technical solutions:

A kind of open type noise barrier, comprise the H shaped steel being arranged on Bridge guardrail or anti-collision wall, between two H shaped steel of arbitrary neighborhood, more than one or one penetrating screen is installed, described penetrating screen forms arc top higher than the part of H shaped steel to Bridge guardrail or anti-collision wall inside bend.The utility model is a kind of open type noise barrier, by a plurality of unit spliceds, formed, on the guardrail of highway subgrade or bridge both sides according to the distance set aside pre-embedded part of setting, fixing H shaped steel on built-in fitting, part between every two H shaped steel is a unit, in each unit, by more than one or one doubling glass, formed, the utility model is by being made into arc at top 200mm ~ 500mm height and position, reduced part diffraction sound, increased sound insulation factor, simultaneously in the situation that between car and anti-collision wall, distance is constant, aduncate arc top has increased the angle of incidence from car to top, shortened the distance between car and barrier, thereby can improve the difficulty of the object of dishing out, reduce the probability of parabolic.

Described penetrating screen is doubling glass.Doubling glass has the function of sound insulation, also can play the effect of logical light simultaneously, in isolated noise, not isolated light, there is good visual effect and soundproof effect, simultaneously, as urban viaduct, the application such as speedway, also there is the effect that prevents high-altitude junk, under placement in height during object, in the situation that doubling glass is crashed to pieces, glass can not come off yet, thereby guaranteed driving, pedestrian's safety traffic, the material of glass has good daylighting, make pedestrian be unlikely to feel oppressive, smooth glass surface is easy to clean and can keeps lastingly penetrating effect simultaneously.

Described penetrating screen is two, and horizontal pull-up material is installed between two penetrating screens.When penetrating screen is two, its small volume, is convenient to dismounting, meanwhile, also can utilize horizontal pull-up material to increase horizontal stressed, improves whole security performance.

Between described penetrating screen and H shaped steel and between penetrating screen and horizontal pull-up material, retainer spring is installed.With positioning spring card be placed between penetrating screen and H shaped steel and penetrating screen and horizontal pull-up material between, retainer spring is in compressive state, its elastic force that recovers deformation closely cooperates penetrating screen and H shaped steel, is convenient to installing/dismounting, has firm feature attractive in appearance.

The utility model compared with prior art, has following advantage and effect:

1 the utility model is a kind of open type noise barrier, the utility model is made into arc by top 200mm ~ 500mm height and position, reduced part diffraction sound, increased sound insulation factor, in the situation that between car and anti-collision wall, distance is constant, aduncate arc top has increased the angle of incidence from car to top, has shortened the distance between car and barrier simultaneously, thereby can improve the difficulty of the object of dishing out, reduce the probability of parabolic;

2 the utility model are a kind of open type noise barriers, and doubling glass has the function of sound insulation, also can play the effect of logical light simultaneously, in isolated noise, not isolated light, has good visual effect and soundproof effect, simultaneously, as application such as urban viaduct, speedways, also there is the effect that prevents high-altitude junk, under placement in height during object, in the situation that doubling glass is crashed to pieces, glass can not come off, thereby guaranteed driving, pedestrian's safety traffic;

3 the utility model are a kind of open type noise barriers, compare with traditional sound barrier, have attractive in appearance, light transmission good, inhale that sound-proofing is strong, outdoor weather resistance is high, ageing resistance good, from heavy and light, long service life, coordination of landscape, the advantage such as elegant in appearance, being applicable to multiple acoustic enviroment noise abatement, is the noise reduction new product of following modern city the best.
