Reverberation room end 5, the four steel pipes 19 that the first sound barrier 11 covers at cell 10 by the first damping layer 12 cover at sound attenuation room end 6 by the second damping layer 18; In cell 10, by the first sound barrier 11 to the direction of the 3rd sound barrier 19, fill successively the second sound barrier 13, the first sound absorbing layer 15, resonance sound-absorbing sound barrier 16 and the second sound absorbing layer 17.
The thickness of the first sound barrier 11 and the 3rd sound barrier is respectively 1mm-5mm, and the thickness of the second sound barrier is 2mm-10mm, and the thickness of resonance sound-absorbing sound barrier 16 is 0.3mm-2.5mm.
The design of the utility model acoustical laboratory sound proof window adopts the technological means such as multilayer sound absorption, sound insulation, damping, has realized wide band large sound insulation factor, and the maximum sound insulation factor of high band can arrive more than 80 decibels.The sound insulation factor that solved test hole, existing laboratory is low, sound tunnel, the defect such as be inconvenient to install.
The installation of the first housing, the second housing:
1, the first housing 2 use expansion bolts are fixed to by fabrication hole on the concrete wall at sound attenuation room place, then by beating the blocking technological holes that expansion bolt uses, live; Penetration concrete from grout hole, filling process must guarantee to fill, fill with real, and space can not be left in inside.
2, first weld movable nut, nut calling hierarchy 10.9; Nut rear is welded a sleeve seal again, and while preventing from being in the milk, concrete blocks nut.The second housing 3 use expansion bolts are fixed to by fabrication hole on the concrete wall at sound attenuation room place, then by beating the blocking technological holes that expansion bolt uses, live; Penetration concrete from grout hole, filling process must guarantee to fill, fill with real, and space can not be left in inside.
3, between the first housing 2 and the second housing 3, gap seals with elaxtic seal.
During concrete use:
At assigned position weld bolt sleeve, must keep sleeve vertical with angle steel and steel tube surface, polish weld seam, keep angle steel and steel tube surface smooth.
In steel pipe, carry out concrete grouting, increase sound insulation factor.Grouting must be closely knit, can not have the phenomenons such as cavity, hollowing, prevents sound insulation weak link.The Plate Welding shutoff of square tube frame two ends.
Must not there is the phenomenons such as bending in frame welding, in order to avoid impact is installed, in commissure, by butyl damping glue, seal.
Sound proof window agent structure:
Sound proof window main body construction is undertaken by order from right to left by drawing, guarantees that each component is in place.
2mm steel plate sticks 2.0mm butyl damping glue (double-sided belt glue), prevents that steel plate vibration is transaudient, increases sound insulation factor.This damping steel plate is fixed on to steel structure frame external surface through riveted joint or welding procedure, and with the gap between sealant sealing steel plate and framework.
In each lattice of steel structure frame, place 3.0mm the second sound barrier and paste with butyl damping glue, and sealing by butyl damping glue or silica gel in the surrounding of the second sound barrier, playing the effect of fixing the second sound barrier simultaneously.
Install the 1.0mm steel plate that floats in the middle of the framework additional, the acoustical cottons such as polyester fiber or glass are filled in steel plate both sides, and the hangnail of steel plate both sides welding some is in order to fixing acoustical cotton.In steel plate surrounding, place resilient rubbber cushion, will float steel plate and frame construction separate, and disconnect overhead speaker, strengthen sound absorption and insulation effect.
Again toward left side, structure is that 2mm steel plate sticks 2.0mm butyl damping glue the cell of frame construction is sealed, and is connected rivet pitch 140～170mm with riveted joint or welding manner with the 25x25mm angle bar (in advance with frame welding) on framework.
Next be 30mm " felt+EVA+ felt " covering 1mm perforated plate, perforated plate is connected and fixed through " felt+EVA+ felt " and 2mm steel plate with screw, and screw adjustable " felt+EVA+ felt " thickness, makes it reach desired size simultaneously.
Welding stiffener and round steel in horn mouth wedge structure, the sound absorption material that can support when strengthening bell-mouthed intensity, fixedly fill in horn mouth.
Horn mouth is filled after the acoustical cottons such as polyester fiber or glass, with riveted joint or welding for framework, connected part should be in advance with frame welding or be riveted into one.
The test hole at main body middle part is formed through Precision Machining such as millings by a monoblock steel billet, guarantees that forms are in the sound insulation factor at this position, also can guarantee simultaneously and test frame between sealing.
Test frame structure and installation:
Test frame and sound proof window main body middle part installing hole adopt the sealing of step tongue and groove form, location, and sound proof window middle part installing hole step tongue and groove surrounding adopts precision optical machinery processing, guarantees sealed precision.
Test frame is by steel plate, measured material or the part of 0.8mm, and the composition such as outer ring pressing plate.
Test frame is by bolt, and presses code to be fixed on a steel structure frame position for window main body by abnormity, uses elaxtic seal sealing, anti-leak-stopping sound on contact surface.
Forklift hole shutoff partiting sound member:
Forklift hole plugging block also adopts damping sound absorption structure, and surrounding and flange place are coated elaxtic seal, produce certain interference fit while making shutoff, prevent slit source sound.
Plugging block is divided into sound insulation side seal sprue and sound absorption side seal sprue, two forklift holes, totally four.
In plugging block, the handle of installing is convenient in design.
Lay frock:
After sound proof window takes off, be positioned over laying in frock of ground.This Fixture Design step (pad cushion blocking) and spike, prevent from damaging by pressure forms lower edge, more prevents from toppling over.
Lay frock middle ware apart to be applicable to fork truck arm between left and right apart from being advisable, facilitate fork truck to insert.
The above-mentioned description to embodiment is can understand and use the utility model for ease of those skilled in the art.Person skilled in the art obviously can easily make various modifications to these embodiment, and General Principle described herein is applied in other embodiment and needn't passes through performing creative labour.Therefore, the utility model is not limited to above-described embodiment, and those skilled in the art are according to announcement of the present utility model, and not departing from the improvement that the utility model category makes and revise all should be within protection domain of the present utility model.
