Abstract
The high-efficient noise-insulation room designed by the utility model adopts various hermetic measures to enhance noise insulation factor over 30 dB which exceeds 25 dB based on theoretical calculation and former engineering practice.
Description
The utility model relates to a kind of noise abatement sound arrester.
Soundproof room is to improve working conditions in the strong noise place and protect the healthy equipment of workman, and it is widely used in industrial and mining enterprises such as power plant and machine-building.The sound insulation factor of past soundproof room is all below 25 decibels.Calculate by theoretical: adopt 1.5 millimeters cold-rolled steel sheets, its sound insulation factor:
TL=13.5Lgm+13 decibel=27.46 decibel
Steel plate thickness is doubled, and its sound insulation factor also only is increased to 31.5 decibels.Therefore the cost height can not increase much effects, particularly steel plate and not do sound absorption and handle that then sound insulation factor is lower, by formula:
TL reality=TL-10Lga=7.46 decibel
(a---steel plate average sound absorption coefficient is 0.01)
Moreover door and window seam hole leakage sound that volume is descended is a lot, by formula:
TL＝10Lg。(---porosity)
Hole surpasses 1/100 o'clock sound insulation factor just can not be above 20 decibels.
The utility model has taked following measures that actual sound insulation factor is reached more than 30 decibels: the soundproof room observation port adopts double-layer rubber weather strip (past is to use the individual layer aluminium layering); The soundproof room door adopts wedge soft junction structure (past is to connect firmly with notch); Adopt fiberboard to fix with the bonding self-tapping screw of epoxide-resin glue to outer wall, inwall adopts double applying panel (past is to use perforated plate) all around; The soundproof room top has increased the double applying panel; The slit is increased interface edge-pressing strip and sealing mat; 3～5 microns higher super glass wools of employing sound absorption coefficient are filled in the centre make sound absorption material.
Embodiment of the present utility model:-----
The high noise abatement sound soundproof room that the utility model is designed, the cube of forming by surroundings wall, top board and door and window sound insulation maisonette.Its observation port adopts the double-layer glass with the rubber strip sealing; Adopt wedge shape soft junction structure between its door and the doorframe; Its outer wall is pasted the porous fibre plate, and its inwall and top board adopt the double applying panel; Interface edge-pressing strip and sealing mat sealing are all used in its whole slits, and each middle filling partly all adopts 3～5 microns super glass wools to make sound absorption material to it.Its detailed coupling arrangement is referring to following each accompanying drawing:
Accompanying drawing (one): 1. framework steel plate; 2. float glass; 3. rubber weather strip.The sound insulation observation port adopts double-layer glass, adopts rubber weather strip bonding between glass and framework steel plate.
Accompanying drawing (two): 4. doorframe; The door; 6. sound absorption material; 7. closed structure.
The soundproof room door adopts wedge shape soft junction structure, uses polyurethane foam plastic and resin artificial leather as encapsulant between door and doorframe, and quilt door and doorframe compress the back and strengthen defening effect.
Accompanying drawing (three): 8. cold-rolled steel sheet; 9. epoxide-resin glue; 1.0. porous fibre plate; 1.1. sound absorption material; 1.2. double applying panel.Outer wall adopts the porous fibre plate to add the epoxy resin glue bond, fixes with self-tapping screw, and inwall adopts the double applying panel all around.
Accompanying drawing (four): 1.3. double applying face perforated plate, set up double applying face perforated plate at the soundproof room top.
Accompanying drawing (five): 1.4. cold-rolled steel sheet; 1.5. interface edge-pressing strip; 1.6. self-tapping screw; 1.7. the sound absorption sealing mat increases the sound absorption sealing mat in the middle of the soundproof room wall cold-rolled steel sheet butt joint, the outside with self-tapping screw with interface edge-pressing strip fixing seal.
Claims (5)
1, a kind of noise abatement sound soundproof room is characterized in that the cube sound insulation maisonette that it is made up of four walls, top board and door and window, its observation port adopts the double glazing unit with the rubber strip sealing, its door and doorframe wedge shape soft junction structure, its outer wall is pasted the porous fibre plate, its inwall and top board adopt the double applying panel, interface edge-pressing strip and sealing mat sealing are all used in its whole slits, and each partly middle filling all adopts 3～5 microns super glass wools to make sound absorption material to it.
2, sound arrester as claimed in claim 1 is characterized in that its sound insulation observation port adopts double-layer glass, adopts rubber weather strip bonding between glass and framework steel plate.
