Abstract
The utility model discloses a kind of glass fiber reinforced plastic sound barrier, including face cover sheet, back side backplate, it is characterized in that, face cover sheet is fiberglass drawing and extruding section bar perforated plate, back side backplate is fiberglass drawing and extruding section bar plate, the two ends of back side backplate have bending section, bending section includes the first bending section, second bending section, the back side of face cover sheet has two symmetrically arranged L-shaped fixtures, a groove inserted for second bending section is formed between L-shaped fixture and described face cover sheet, the outer face of one of them the first bending section has tenon, the outer face of another the first bending section has tongue-and-groove, there is between face cover sheet and the back side backplate implant.Face cover sheet and back side backplate are assembled by way of engaging, arrange bending section and corresponding tongue-and-groove structure by overleaf backplate, and the glass fiber reinforced plastic sound barrier that can be provided two pieces of this utility model is attached to together by way of tongue and groove cooperation, easy for installation, quick.
Description
Technical field
This utility model is related to sound-screen barrier technique, and in particular to a kind of glass fiber reinforced plastic sound barrier.
Background technology
As country greatly develops communication, the quantity of sound barrier is continuously increased, form constantly develops, the height of sound barrier
Degree, mounting means and acoustic tile material are also progressively being improved.
The content of the invention
For problems of the prior art, this utility model provides a kind of glass fiber reinforced plastic sound barrier, face cover sheet and the back of the body
Face backplate is assembled by way of engaging, arranges bending section and corresponding tongue-and-groove structure by overleaf backplate, can be by two pieces
The glass fiber reinforced plastic sound barrier that this utility model is provided is attached to together by way of tongue and groove cooperation, easy for installation, quick.
To solve above-mentioned technical problem, the technical solution adopted in the utility model is, a kind of glass fiber reinforced plastic sound barrier, including just
Face backplate, back side backplate, face cover sheet are fiberglass drawing and extruding section bar perforated plate, and back side backplate is fiberglass drawing and extruding section bar plate, is carried on the back
The two ends of face backplate have bending section, and bending section includes the first bending section, the second bending section, and the back side of face cover sheet has two
Symmetrically arranged L-shaped fixture, forms one for second bending section insertion between L-shaped fixture and described face cover sheet
Groove, the outer face of one of them the first bending section have tenon, and the outer face of another the first bending section has tongue-and-groove, front
There is between backplate and the back side backplate implant.
Described implant is the centrifugal compound glass cotton that alkali-free hydrophobic glass-fiber-fabric or waterproof sound absorption thin film are wrapped up.
The beneficial effects of the utility model are：Face cover sheet and back side backplate are assembled by way of engaging, by the back of the body
Face backplate arranges bending section and corresponding tongue-and-groove structure, and the glass fiber reinforced plastic sound barrier that can be provided two pieces of this utility model is by enterprise
The mode that mouth coordinates is attached to together, easy for installation, quick.
Description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of face cover sheet.
Specific embodiment
In conjunction with accompanying drawing, the utility model is described in further detail.
Such as Fig. 1 and Fig. 2：A kind of glass fiber reinforced plastic sound barrier, including face cover sheet 1, back side backplate 2, face cover sheet is fiberglass
Drawing and extruding section bar perforated plate, back side backplate are fiberglass drawing and extruding section bar plate, and the two ends of back side backplate have bending section, and bending section includes
First bending section, the second bending section, the back side of face cover sheet have two symmetrically arranged L-shaped fixtures 6, L-shaped fixture with
A groove 7 inserted for second bending section, the outer end of one of them the first bending section are formed between described face cover sheet
Face has tenon 4, and the outer face of another the first bending section has tongue-and-groove 5, has filling between face cover sheet and back side backplate
Thing 3.
Described implant is the centrifugal compound glass cotton that alkali-free hydrophobic glass-fiber-fabric or waterproof sound absorption thin film are wrapped up.
This product major advantage：First, selection, structure are novel, do not need any metal material, be exposed to ring in whole product
The phenomenons such as aging, corrosion will not occur in border；2nd, intensity is high, and anti-bending bearing capacity >=5.29KN/ ㎡ is unlikely to deform；3rd, conduct oneself with dignity
Gently (weight≤16 ㎏/㎡), it is possible to decrease sound barrier basis is brought convenience with the requirement of strength design of column and to in-site installation；
4th, landscape effect is preferable, can be designed to a variety of patterns according to user's requirement mutually harmonious with environment；5th, sound absorption effect
Ideal, noise reduction coefficient NRC >=0.8, weighted transmission loss Rw >=30dB (A) can meet the requirement of various sensitive point for noise；6th, after
Phase is easy to maintenance, invariant color, easy cleaning, be damaged after easily replace；7th, the product has antitheft, the work(such as survivable, damage
Energy.The product can comprehensively, widely apply to all kinds of road noise barrier engineerings.
For a person skilled in the art, still the technical scheme described in foregoing embodiments can be repaiied
Change, or equivalent is carried out to which part technical characteristic, all within spirit of the present utility model and principle, that what is made is any
Modification, equivalent, improvement etc., should be included within protection domain of the present utility model.
