As preferably, described rock cotton board outerwrap one deck hydrophobic nonwoven layer.The sound insulation part is the composite construction that carbon steel sheet, rock wool and nonwoven are formed, and coats rock cotton board through the hydrophobic nonwoven, guarantees the sealing of rock wool, makes it have good weatherability.
As preferably, said aluminum fiber acoustic board together with lightgage steel joist, rock cotton board together with zinc-plated carbon steel sheet all be fixed on constitute said framework, between the outer rim square steel at the up and down edge of plate face, be provided with inner square steel between lightgage steel joist end and the outer rim square steel; The part that the zinc-plated carbon steel sheet of layer of aluminum fiber sound absorption plate, one deck outside being positioned at exceeds lightgage steel joist and rock cotton board is close to outer rim square steel surface; And be fixedly connected with the outer rim square steel through sealant layer; Be positioned at the inboard zinc-plated carbon steel sheet of one deck and one deck lightgage steel joist and fit, described galvanized steel plain sheet also plays except that playing the sound insulation effect and supports and sealing function.
Above-mentioned aluminum fiber acoustic board, sound insulating structure connect, assemble through square steel framework, lightgage steel joist, leave certain space through lightgage steel joist between sound insulating structure and the aluminum fiber acoustic board, the structure of inhaling (sound) outer separated (sound) in forming at last; Adopt the purpose of sealant layer sealing to be to guarantee that rock cotton board is hedged off from the outer world, avoid steam entering or rock wool fibers to disperse.
As preferably, between described outer rim square steel and the inner square steel, be fixedly connected through connector between inner square steel and the lightgage steel joist.
In sum, the utility model compared with prior art has following advantage.
The sound absorption and insulation sheet material that the utility model provides is the outer structure at a distance from (sound) of interior suction (sound), plays noise reduction to greatest extent, effectively improves the regulation effect for low-frequency noise.
The utility model can reach excellent low frequency absorption performance owing to adopt the double resonance sound absorption construction, and takes into account the absorption band of broad simultaneously, takes into account the medium-high frequency acoustically effective.
The utlity model has good environmental-protecting performance, the resistance acoustical board that aluminum fiber acoustic board is formed is an all-aluminium construction, the convenient recycling; Rock wool by hydrophobic nonwoven and zinc-plated carbon steel sheet parcel has effectively played the isolated of rock wool and space outerpace, has improved weather-proof, ageing resistace, avoids the rock wool sound absorbing capabilities that makes moist to descend, and the wearing out and disperse of rock wool fibers.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Embodiment 1.
Shown in Figure 1, a kind of sound absorption and insulation sheet material comprises sound absorption construction 1 and sound insulating structure 2, and the framework that is used to support sound absorption construction and sound insulating structure.
Shown in Figure 2, described sound absorption construction 1 is arranged by two-layer aluminum fiber acoustic board 9 and is constituted, and forms cavity 8 between the two-layer aluminum fiber acoustic board 9, and said two-layer aluminum fiber acoustic board 9 is separately fixed on the two-layer lightgage steel joist 7 that constitutes said framework.
Described sound insulating structure 2 constitutes these rock cotton board 4 outerwrap one deck hydrophobic nonwoven layer by clamping rock cotton board 4 in the middle of the two-layer zinc-plated carbon steel sheet 3.
Said aluminum fiber acoustic board 9 together with lightgage steel joist 7, rock cotton board 4 together with zinc-plated carbon steel sheet 3 all be fixed on constitute said framework, between the outer rim square steel 5 at the up and down edge of plate face.
Rock cotton board 4 adopts the hydrophobic nonwoven to carry out integral coating, guarantees the sealing of rock cotton board, has good weatherability; In the zinc-plated carbon steel sheet 3 that coats after good rock cotton board 4 front and back are provided with 2 ~ 3mm, sandwich structure consisting is assembled through square steel framework and two-layer aluminum fiber acoustic board 9 again.
In sound absorption and insulation sheet material assembling process; Lightgage steel joist 7 compresses the sound insulation sandwich structure with the framework that outer rim square steel 5 is formed; Lightgage steel joist 7 has guaranteed the cavity 8 between the two-layer aluminum fiber acoustic board 9, and the space (sound absorption construction back of the body chamber) between aluminum fiber acoustic board 9 and the sound insulation sandwich structure; In sound absorption construction, aluminum fiber acoustic board 9 is the panel of sound absorption and insulation sheet material as a whole, and directly in the face of sound source, zinc-plated carbon steel sheet 3 is the backboard of sound absorption and insulation sheet material as a whole then; During assembling, connect through bolt between lightgage steel joist 7, the square steel or be welded to connect and all can.
Sound absorption and insulation sheet material principle aluminum fiber acoustic board 9 is a kind of resistance sound absorption materials; Its absorption peak is generally about 500Hz; Have the sound absorption coefficient about 0.2 at 125Hz, promptly have acoustically effective preferably, but be difficult to satisfy the broad sound sucting band in low-frequency range; Therefore; Through double-deck acoustical board and cavity 8 (between the two-layer aluminum fiber acoustic board 9), back of the body chamber (aluminum fiber acoustic board 9 with sound insulation sandwich structure between) acting in conjunction, the sound absorption construction 1 of composition double resonance reaches the purpose of widening absorption band; And the sandwich structure that the zinc-plated carbon steel sheet of rock cotton board and two bed thickness 3 is formed is a kind of good compound sound insulating structure 2, can reach necessary defening effect, than simple metal sound barrier lightweight and be easy to processing more; Adopt and inhale (sound) outer structure at a distance from (sound) in above-mentioned, can effectively absorb and intercept low-frequency noise, the noise that is specially adapted to places such as indoor substation is controlled.
The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the spirit of the utility model or surmount the defined scope of appended claims.
