The specific embodiment
The utility model feature and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that technician's of the same trade understanding:
As shown in Figures 1 to 4, always represent respectively: front panel 1, postnotum 2, centrifugally glass-wool layer 3, FC plate 4, black waterproof sound absorption paper 5, jut 6, depressed part 7, first kink 8, second kink 9, the 3rd kink 10, the 4th kink 11, bridge type rubber pad 12, upper mounted plate 13, bottom plate 14, bolt 15, pad 16, cavity layer 17, cavity layer 18, side plate 19 with reference to label 1-19.
Referring to Fig. 1-2, the sound barrier described in the present embodiment comprises that one roughly is rectangular-shaped body, and this body comprises front panel 1, postnotum 2, and the parallel web of being located between front panel 1 and the postnotum 2.
Web is stacked successively by front and back and the centrifugally glass-wool layer 3 and the FC plate 4 of bolt constitute.Centrifugally glass-wool layer 3 thickness are 50mm, unit weight 48 Kg/m
3Also be covered with black waterproof sound absorption paper 5 on centrifugally glass-wool layer 3 outside, the outside herein refers to the outside that centrifugally glass-wool layer 3 constitutes web one side.FC plate 4 thickness are 10 mm.FC plate 4 and centrifugally glass-wool layer 3 pass through circular gasket 16 bolts of four bolts 15 and thickness 1.5mm, diameter 80mm to constitute one.
Web is divided into two independently cavity layers with body interior, and wherein cavity layer 18 thickness between centrifugally glass-wool layer 3 and the described front panel 1 are 40mm, and cavity layer 17 thickness between FC plate 4 and the postnotum 2 are similarly 40mm.
Thus, the front panel 1 of perforation forms resonance sound-absorbing structure with the cavity layer of back 40 mm 18, and it is better than directly add sound absorption material behind the perforation aluminium alloy plate to the sound absorbing capabilities of all-bottom sound.Centrifugally glass-wool layer 3 is acoustical materials of a kind of better controlled noise, proves through engineering practice, and it has good sound absorption performance in the frequency band range of broad.In centrifugally glass-wool layer 3 back, FC plate 4 constitutes the double-deck sound-proof wall plated construction of a kind of lightweight with cavity layer 17 and postnotum 2, and it has good sound insulation property in the frequency band range of broad.
More than for the present embodiment general configuration and purpose is set is described, below in conjunction with said structure between concrete connected mode be described:
Separate by upper mounted plate 13 and bottom plate 14 between front panel 1, postnotum 2, centrifugally glass-wool layer 3 and the FC plate 4, wherein upper mounted plate 13 and bottom plate 14 are the elongated aluminium alloy extrusions of length direction, side that one of this upper mounted plate 13 and bottom plate 14 are relative is provided with two grooves of coupling, wherein a groove is used for plug-in mounting centrifugally glass-wool layer 3, and another groove is used for plug-in mounting FC plate 4.Upper mounted plate 13 and all vertical side plate that is provided with in bottom plate 14 both ends are fitted on this side plate and are provided with front panel 1, postnotum 2.Thus, front panel 1, postnotum 2, centrifugally glass-wool layer 3 and FC plate 4 can be realized the structure of setting at interval.
The body upper surface has the jut 6 that a cross section is isosceles trapezoid, and described body lower surface has one in the depressed part 7 of described jut 6 form fit, and the inwall of depressed part 7 is fitted and is provided with a bridge type rubber pad 12 simultaneously.This jut 6 forms with depressed part 7 and cooperatively interacts, bridge type rubber pad 12 is compressed sealing, that so both can realize that sound barrier in the present embodiment implements vertically stacks, this kind structure by making a body the lower surface and the upper surface of another body realize seamless link, can effectively stop the leakage of noise source.
Referring to Fig. 3, Fig. 4, the concrete structure of jut 6 and depressed part 7 is: described front panel 1 upper limb is bent with first kink 8, described postnotum upper limb is bent with second kink 9, described first kink 8 constitutes the upper surface of described body and protrudes from the jut 6 of upper surface, and the structure of described second kink, 9 formations and first kink, 8 form fit also is overlapped in its inboard; Described front panel 1 upper limb is bent with the 3rd kink 10, described postnotum 2 upper limbs are bent with the 4th kink 11, the lower surface of the described body of described the 4th kink 11 formations and recessed in the depressed part 7 of lower surface, described the 3rd kink 10 constitutes and the structure of the 4th kink 11 form fit also is overlapped in its outside.
Bending structure described above, except being used for forming jut 6 and the depressed part 7, overlap joint by between first kink 8 and second kink 9 has limited forward and backward being positioned between front panel 1 and the postnotum 2, and conflicts mutually between front panel 1 and the postnotum 2; Overlap joint by between the 3rd kink 10 and the 4th kink 11 has limited forward and backward being positioned between front panel 1 and the postnotum 2, and conflicts mutually between front panel 1 and the postnotum 2.And the bending of 2 liang of outer rims of described postnotum symmetry to be constituting described body biside plate, and the 1 liang of outer rim symmetry bending of described front panel also is overlapped within the described body biside plate on the side.Thus, both can realize the snapping that to be connected between front panel 1 and the postnotum 2, and then front panel 1, postnotum 2, centrifugally glass-wool layer 3, FC plate 4, upper mounted plate 13 had been connected as one with bottom plate 14.
