Description
Technical field
The present invention relates to a kind of sound-insulating and heat-insulating structures, more particularly, to a kind of bulkhead sound-insulating and heat-insulating composite construction.
Background technique
With the continuous improvement required cabin inhabitation noise circumstance, the cabin bulkheads such as ship, ocean platform are meeting original
While having heat-insulating, fire-preventing requirement, sound insulation property is also required to constantly be promoted.According to mass law it is found that increasing bulkhead
Its sound insulation property can be improved in surface density, but weight doubles, sound insulation property could improve 6dB, to ship, ocean platform
Loss of weight is very unfavorable, and sound insulation property improves also very limited.Increase by one layer of air layer in siding, is the one kind for improving sound insulation property
Common method, but when air layer is relatively thin, very little is helped to the raising of siding sound insulation property, when air layer is thicker, and can be occupied
Biggish space, and increase air layer and very big difficulty is both increased to design, the manufacture of structure.
Sound-absorbing material or structure are used inside siding, improves the sound absorbing performance inside siding, are penetrated to reach reduction
Acoustic wave energy improves the purpose of siding sound insulation property, is another common method.Currently, for heat-insulated needs, inside bulkhead
It is filled with heat-barrier material, these materials are mostly inorfil blanket class material, while heat-insulated, also can play one to sound wave
Fixed absorption.Sound absorbent perforated structure is a kind of sound absorption structure more commonly used at present, by aperture, porosity, plate
The parameters such as thickness, cavity depth are designed, the sound sucting band of adjustable perforated plate.Chinese patent CN102296715A is disclosed
A kind of sound insulating structure of tape punching plate, the structure are mainly made of top panel, lower panel, perforated plate and side panel, perforated plate with
The surrounding in folded space is blocked by side panel and constitutes two chambers between top panel and lower panel, the two chambers respectively with
Perforated plate constitutes resonant silencing structure.Chinese patent CN205475789U discloses a kind of micropore sound absorption and insulation composite construction, should
Structure is hardened by micropunch by minimum one piece of microperforated panel forms between honeycomb interlayer and honeycomb interlayer between two-layer panel, panel
The sound absorption energy consumption effect of structure improves integrally-built soundproof effect, while increasing the rigidity of structure.Although above two structure
Sound absorbent perforated structure is applied, improves integrally-built sound insulation property, but due to not taking effective provision for thermal insulation, it is whole
The heat-proof quality of structure is bad.
In conclusion the sound insulation value needs of traditional bulkhead composite construction further increase, and existing sound insulation composite junction
Structure does not take effective provision for thermal insulation, and integrally-built heat-proof quality is bad, is both difficult to meet when scuttle bulkhead composite construction
The technical requirements for the features such as having both sound insulation, heat-insulated, lightweight.
