Abstract
The utility model relates to a sound insulation and absorption screen for construction sites, which comprises a main body of a sound insulation and absorption screen; the cross section of the main body is provided with a compound dividing wall structure; the side edge of the main body is provided with a safe edge; the periphery of the main body is distributed with a hole used for connection; the safe edge is provided with a hole used for connection; the compound dividing wall structure is alternatively arranged through sound insulation and sound absorption materials. The utility model has the advantages of compact structure, convenient assembly and favorable effect on sound insulation and absorption.
Description
The utility model relates to a kind of construction site sound insulation sound-absorbing screen that is used for.
How to reduce the influence of construction noise to surrounding resident, reduce the phenomenon that disturbs residents, it is a great problem of puzzlement enterprise in charge of construction always, in order to solve the job site noise reduction, the domestic unit in charge of construction that has has tried out 1.5 * 3.6m type sound break that a kind of Japanese consonance company produces, and the cost of this sound break is too high, and noise reduction is not obvious, therefore, be necessary a kind of novel sound insulation sound-absorbing screen that is used for construction site.
The purpose of this utility model provides a kind of novel construction site sound insulation sound-absorbing that is used for shields, and this sound-absorbing screen is easy to assembly, and the sound insulation sound-absorbing effect is good.
For achieving the above object, the utility model is taked following design scheme: a kind of construction site sound insulation sound-absorbing screen that is used for comprises: sound insulation sound-absorbing screen main body, and the main body section is a compound wall construction, the main body side sideband has safe edge, the main body surrounding is evenly equipped with to connect and use hole, safe edge to have connection to use the hole.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation.
Fig. 2 is the cross-sectional drawing of sound insulation sound-absorbing screen main body among Fig. 1
Fig. 3 is the utility model partial perspective view
Among Fig. 1, Fig. 3,1 is sound insulation sound-absorbing screen main body, and the main body section is a compound wall construction, its layer be the sound insulating material layer, can adopt surface density greater than 1kg/m
2Flexible material, the intermediate layer is a damping material, its 8 octave average sound absorption coefficients are between 0.2-0.9, internal layer is a film material, main body can be greater than three layers, for example four, five, six layers etc., wherein are still sound insulation, damping material is alternately arranged.Main body is a rectangle among the figure, and each fixes its two sides sound insulation safe edge, a safe edge and can work the effect of screening, and respectively there is an aperture at the safe edge both ends, also can each two hole, three holes etc.The surrounding of main body is evenly equipped with to connect uses the hole.
Among Fig. 2,1-1 is the sound insulating material layer, adopts the fiber resin, and 1-2 is sound-absorbing material layer, adopts glass fiber 1-3 to adopt fiber resin etc. for the film material layer.
When the utility model was applied to the job site, the sound-absorbing that each can be insulated against sound screen connected with the rope perforation, and was support with the scaffold.
The utility model advantage: compact conformation, easy to assembly, sound insulation sound-absorbing effect good.
