Abstract
The utility model relates to a noise control device of green construction in the urban center, in particular to a mobile noise barrier. The device is composed of a pulley handcart and a noise barrier which is fixed on the pulley handcart through connectors and is made of sound isolation and absorption board material. According to the target noise reduction amount in the construction field and surrounding areas as well as the site construction conditions, the mobile noise barrier is designed by combining the technology of the road noise barrier and the isolation barrier of common construction. The noise barrier is fixed and connected with a movable device, thereby realizing the goal that the noise barrier moves along with the main noise source within the boundary of a construction site and finally achieving the effect of noise diminution. The noise source of the construction field in the urban area can be isolated, thereby ensuring that the noise within the boundary of a construction site is lower than the limited value of the national standard and that the noise is decreased to the background noise of the region to the greatest extent.
Description
Technical field
The utility model relates to the oise damping means of a kind of down town green construction, relates in particular to a kind of packaged type sound barrier.
Background technology
Urban architecture construction boundary noise pollution situation is more serious, and is especially obvious in the central area, metropolis.Among the State Standard of the People's Republic of China GB12523-90 " building operations boundary noise level limit " to inside, urban architecture construction period construction plant and surrounding area, because the noise that construction produces has been made limit value---the highlyest must not surpass 75dB, to control the noise pollution of urban environment.At present, mainly be fixing board wall is set or limits the mode of engineering time and carry out the control of noise by the building boundary, its defening effect is relatively poor.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of packaged type sound barrier that can effectively isolate the construction plant noise, to overcome the shortcomings such as defening effect difference that prior art exists.
The technical scheme of the utility model technical solution problem is as follows:
A kind of packaged type sound barrier is characterized in that, comprises sound barrier and pulley wooden handcart, and described sound barrier is fixedly installed on the pulley wooden handcart by connector, and described sound barrier is sound insulation or sound absorbing plate.
Further, described sound barrier also comprises crossbeam, column, basis, connection securing member; Described column vertically is fixedly installed on the pulley wooden handcart by the basis, and described beam vertical is arranged between sound insulation or sound absorbing plate and the column in column, and the intersection interconnects by connecting securing member between described crossbeam, column and sound insulation or the sound absorbing plate.
The utility model packaged type sound barrier passes through in conjunction with road noise barrier and common construction isolation barrier technology, the relevant design that hot-tempered amount and construction condition are carried out sound barrier is fallen according to construction and the target of perimeter zone, and by with the fixedlying connected of movable fixture, realize sound barrier in the construction boundary with the master
The utility model packaged type sound barrier passes through in conjunction with road noise barrier and common construction isolation barrier technology, the relevant design that hot-tempered amount and construction condition are carried out sound barrier is fallen according to construction and the target of perimeter zone, and by with the fixedlying connected of movable fixture, realize the target that sound barrier moves with the main noise source in the construction boundary, finally reach the effect of reducing noise.Realize the technology application of packaged type sound barrier in the urban architecture construction boundary.Wherein, the vehicle sound barrier of traffic route engineering mainly is resident and the Office Area at the road both sides, the fixed head or the wall of the compact material with sufficient density are set between noise source and acceptance point, realizing the significant additional attenuation of sound wave, its design process mainly comprises aspects such as the selection, parameters,acoustic design, sound barrier size design, structural element design of acoustic barrier material and form; Common urban architecture construction boundary isolation barrier then just adopts fixing board wall on the construction border, so that the construction plant is isolated from the outside, and plays certain noise isolation effect.
The utility model can be isolated the noise source in the building operations place, down town, to realize that building operations boundary noise is lower than the limit value of national standard, and reduce to this regional background noise as far as possible, can be widely applied to association areas such as builing industry, civil engineering.
