Detailed description of the invention
Below in conjunction with accompanying drawing, technical solutions of the utility model are described in detail:
As shown in Figure 1,2,3, 4, the resistance isolation booth that the utility model realizes, primarily of internal layer sound barrier 1, air layer 2, outer sound barrier 3, internal layer is floating builds system 4, and outer floating builds system 5, intake muffler 6, exhaust silencer 7, interlock Double-layer sound-insulation door 8, Double-layer sound-insulation transparency window (if any specific use, window can be cancelled) 9 forms.
Wherein, internal layer sound barrier 1: internal layer sound barrier is micropunch double-layer cavity acoustical board, and cavity divides two-layer, inside cavity non-filler.Described acoustical board comprises panel, backboard and sounding board, forms the first cavity between panel and sounding board, forms the second cavity between sounding board and backboard, and panel and sounding board all arrange several micro-drill(ing).First cavity thickness is 50mm, and the second cavity thickness is 50-100mm.Panel is perforated percentage 1%, aperture 0.1mm, and micro-drill(ing) is the microperforated panel of equilateral triangle arrangement.Sounding board is the microperforated panel of perforated percentage 2%, aperture 0.2mm, and micro-drill(ing) is the microperforated panel of equilateral triangle arrangement.The metal sheet of backboard to be thickness be 1.5-2mm.
Air layer 2: leave air layer between internal layer sound barrier and outer sound barrier, thickness is 50-120mm.
Outer sound barrier 3: structure is the same with internal layer sound barrier 1, does not repeat them here.
Internal layer is floating builds system 4: be made up of internal layer sound barrier 1 and low frequency damping composite damper; Wherein internal layer sound barrier 1 inside need arrange reinforcing rib to strengthen bearing capacity, lays low frequency damping composite damper bottom internal layer sound barrier.
Outer floating builds system 5: be arranged on that internal layer is floating to be built under system 4, be made up of outer sound barrier and low frequency damping composite damper.It is stressed to meet that outer sound barrier inside need arrange reinforcing rib.Low frequency damping composite damper is laid bottom outer sound barrier.
