Abstract
The utility model relates to a composite sound insulation folding screen for noise and radiation reduction of municipal construction and building operation. The utility model is composite compounded by two layers of sound insulation layers, wherein, a sound absorption layer is arranged between the two layers of sound insulation layers; the sound absorption layer can be a monolayer sound absorption layer, or can be a three-layer composite layer composed of the sound absorption layer, a damping sound isolation layer and a sound isolation layer; an adhesive layer is arranged between two layers of base material. The sound absorption layer uses glass wool boards; the damping sound insulation layer uses PVC air duct cloth; the sound insulation layer uses galvanized plates. The utility model has the advantages of simple structure, easy fabrication, low cost and effectively isolated external environment and noise interference caused by construction plants. The utility model can also be used as a sound insulation hood, a sound insulation room or a sound insulation screen for insulation of various noise sources.
Description
The utility model relates to a kind of Composite sound insulation folding screen, is used to reduce the noise that urban construction and building operations give off.
Fast development along with China's economic construction, the companion's and the noise of the urban construction that comes and the building operations problem that disturbs residents is also outstanding day by day, it has become one of primary pollution source of urban environment noise, having a strong impact on resident's life and people's routine work, the rate of complaints of resident is higher, sometimes also cause civil disputation difficult to manage, become a kind of destabilizing factor.Though national departments concerned has been worked out the required standard of building operations boundary noise level limit, many-sided reasons such as limit what China's economic development existing level and municipal administration, construction machine will satisfy the required standard limit value, and its difficulty is bigger.
The purpose of this utility model is to provide a kind of Composite sound insulation folding screen at the problem of above-mentioned existence, it can reduce effectively or the noise of isolated urban construction, building operations to the radiation of surrounding environment, alleviated the influence that the noise on human live and work is brought.
The purpose of this utility model is achieved in that a kind of Composite sound insulation folding screen, it constitutes by two layers of damping soundproof course is compound, it is characterized in that between two layers of damping soundproof course, being provided with absorbent treatment, its absorbent treatment is the individual layer absorbent treatment, or three layers of composite bed for constituting by absorbent treatment, damping soundproof course and soundproof course, be provided with adhesive layer between damping soundproof course and the absorbent treatment or between damping soundproof course and the soundproof course.Damping soundproof course in aforementioned adopts PVC air duct cloth material, and absorbent treatment is the block of glass wool material, and soundproof course is the galvanized sheet material, and adhesive layer is a cementing agent.When municipal engineering or building residence engineering construction, play the construction plant with this utility model corral, greatly reduce the noise radiation of environment towards periphery, reduced the noise problem.In addition, also can be used as sound insulation enclosure, isolation booth or the acoustic screen of isolating all kinds of noise sources.
The utility model is simple in structure, makes easily, and cost of production is lower, has the function of sound insulation, sound absorption, can also satisfy environmental requirements such as fire prevention, waterproof, anticorrosion.As be fixed on the scaffold of building site and also can play the safety barrier effect.Use and simple installation, and reusable.
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
Fig. 1 is the utility model embodiment 1 structure sectional view.
Fig. 2 is the utility model embodiment 2 structure sectional views.
As shown in Figure 1, a kind of Composite sound insulation folding screen, it is by the compound formation of damping soundproof course (1) of two layers of PVC air duct cloth material, it is provided with the absorbent treatment (2) of a bed thickness 15mm block of glass wool material between two layers of damping soundproof course (1), be provided with the adhesive layer (4) of adhesive between damping soundproof course (1) and absorbent treatment (2), this constructed products is referred to as soft Composite sound insulation folding screen, is used for high-rise building residence engineering construction occasion.As shown in Figure 2, between the damping soundproof course (1) of two layers of PVC air duct cloth material, be provided with three layers of composite bed that the soundproof course (3) by the damping soundproof course (1) of the absorbent treatment (2) of thick 15mm block of glass wool material, PVC air duct cloth material and thick 0.5mm galvanized sheet material constitutes, between every layer, be provided with simultaneously the adhesive layer (4) of adhesive, this constructed products is referred to as the hard Composite sound insulation folding screen, be mainly used in urban engineering project, both had sound absorption, sound insulation effect, can be used as the usefulness of safe enclosure wall again.
