Abstract
The utility model provides a multilayer sound-absorbing type sound-attenuating plate which structurally comprises a sound-absorbing layer. Sound-attenuating layers and main body layers are symmetrically arranged on two sides of the sound-absorbing layer from inside to outside. Compared with the prior art, the multilayer sound-absorbing type sound-attenuating plate has the advantages of being reasonable in design, simple in structure, convenient to use, good in sound-absorbing effect, good in durability and acid resistance, low in cost and maintenance expenses and simple and quick to maintain and the like, thus, the multilayer sound-absorbing type sound-attenuating plate has excellent popularization and use value.
Description
Technical field
The utility model relates to the abatvoix technical field, a kind of specifically simple in structure, sound insulation slab of being designed with multiple layer sound suction.
Background technology
Under advocating the main trend environment of environmental protection theory and city noise to people's inhabitation and life influence more and more serious in; People have recognized the harm of noise; For weakening or eliminating the noise people and taked various modes, wherein abatvoix is the most frequently used arriving to this, and abatvoix is meant the tabular material with sound-absorbing noise reduction effect; At present; Abatvoix mainly contains wooden abatvoix, mineral wool abatvoix, cloth art abatvoix and polyester fiber abatvoix, and wherein, what wooden abatvoix adopted is that wood materials is processed; The mineral wool abatvoix is to adopt surperficial treated annular knurl type mineral wool board to process; The cloth art abatvoix is to adopt the rotary glass cotton material to process; The polyester fiber abatvoix is to adopt Polyester Fibers to process.But these abatvoixs are because structure is all comparatively simple, and sound-absorbing effect is unsatisfactory.
Summary of the invention
The technical assignment of the utility model is the deficiency that solves prior art, and a kind of simple in structure, multiple layer sound suction formula sound insulation slab is provided.
The technical scheme of the utility model realizes by following mode, this multiple layer sound suction formula sound insulation slab, and its structure comprises sound absorbing layer, the both sides of said sound absorbing layer are symmetrically arranged with noise reduction layer, body layer from inside to outside.This structure setting is for through the multiple layer sound suction structure is set, and sound is thoroughly absorbed, and guarantees good soundproof effect.
As preferably, be filled with damping material in the said sound absorbing layer.This damping material is meant that sound absorption coefficient reaches the material more than 0.3, and such as acoustical cotton etc., this is as most crucial sound absorbing layer absorption of sound.
As preferably, evenly be provided with sound-absorption hole on the said noise reduction layer.Sound-absorption hole is mainly used in the preliminary absorption of sound do, the unabsorbed last or end syllable of sound absorbing layer is sponged.
As preferably, said body layer by taeniae, horizontal stripe be cross-linked be arranged to netted.This is in order to guarantee the integrally-built fastness of this sound insulation slab.
The beneficial effect that the utility model is compared with prior art produced is:
Characteristics such as that the multiple layer sound suction formula sound insulation slab of the utility model has is simple in structure, easy to use, be skillfully constructed; The utility model adopts the multiple layer sound suction structure; Good, the durable acid resistance of sound-absorbing effect is good, with low cost, maintenance cost is low, maintenance is simple and convenient, has good value for applications.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model.
Mark in the accompanying drawing is represented respectively:
1, taeniae, 2, horizontal stripe, 3, sound-absorption hole, 4, body layer, 5, the noise reduction layer, 6, sound absorbing layer.
The specific embodiment
Below in conjunction with accompanying drawing the multiple layer sound suction formula sound insulation slab of the utility model is done following the detailed description.
Shown in accompanying drawing 1, this multiple layer sound suction formula sound insulation slab, its structure comprises sound absorbing layer 6, the both sides of said sound absorbing layer 6 are symmetrically arranged with noise reduction layer 5, body layer 4 from inside to outside.
Be filled with damping material in the said sound absorbing layer 6; Evenly be provided with sound-absorption hole 3 on the said noise reduction layer 5; 4 layers of said main bodys by taeniae 1, horizontal stripe 2 be cross-linked be arranged to netted.
