Description
Technical field
The present invention relates to a kind of sound barrier, particularly, relate to a kind of MULTILAYER COMPOSITE rack sound barrier, the invention still further relates to a kind of application of MULTILAYER COMPOSITE rack sound barrier.
Background technology
Because people's living standard improves, people are concerned about quality of life more, require improving constantly to the acoustic enviroment of life, work, inhabitation.
Along with Urbanization Process In China constantly advances, the population density increases, and land resources becomes more precious.Due to improving constantly of Building technology level, the development of constructional materials and construction technology, increasing multilayer, Development of High-rise Buildings are got up.A large amount of building adopts reinforced concrete structure, towards high-rise, large bay future development.The development of building structure, makes a large amount of light wall board materials be applied to enclosure wall and the partition wall of building.The application of light wall board material, alleviates the load of structure, saves steel, cement, reduces construction costs, increases the usable floor area of building interior, and easy for installation.In order to reach the effect of good sound absorption, adopting thick and heavy wallboard in a large number at present, occupying larger usable floor area; And once adopt frivolous wallboard, sound insulation property can be caused again to be difficult to meet the demands.
Noise is also the integrated technology index weighing Hyundai Motor manufacture level, and World Automobile Industry Ge great car load manufacturing enterprise and the noise reduction of parts enterprises to automobile are paid much attention to.Automobile body sheet metal part imports the main barrier in car into as prevention outside noise, its acoustical behavior height and the weakening effect close relation to noise, especially for front wall sheet metal component, it is for intercepting the main noise source-engine noise of automobile, and its acoustics effect directly affects the quality of car load.But Metal Sheets for Body-manufacturing is all individual layer steel plate structure, only has deadening, and effect is general, usually on Metal Sheets for Body-manufacturing, adopt the mode of additional damping plate to carry out vibration and noise reducing, but current damping sheet adopt single material usually, as plastics, rubber etc., noise reduction noise reduction effect is not good.
Such as, Chinese patent Authorization Notice No.: CN203905280U, authorized announcement date on October 29th, 2014, disclose a kind of lightweight fireproof insulating Acoustic barrier plate, comprise: the first panel, the second panel, sound absorption heat insulating material and lightgage steel joist framework, the sound absorption heat insulating material be provided with between first panel and the second panel, the first panel of being fixed on of the lightgage steel joist framework that passes through of sound absorption heat insulating material and the second panel between.Also such as, Chinese patent Authorization Notice No.: CN202686211U, authorized announcement date on January 23rd, 2013, discloses a kind of car damping sound insulating panel, auto sound damping sheet be the three-layer composite structure built up successively from top to bottom by top layer, interlayer and bottom.
Although above two pieces patent reaches heat insulation and effect that is noise reduction to a certain extent, the poor effect of heat insulation and noise reduction, still can not meet the more and more higher acoustical demands of people.
Summary of the invention
For the technological deficiency of existing isolating composite plate, the invention provides one
novel, the MULTILAYER COMPOSITE rack sound barrier with excellent sound insulation property, in less thickness dimension, reach higher defening effect, be applicable to sound insulation and require higher construction wall and automobile body.This structure is under the prerequisite of guaranteed strength simultaneously, can alleviate quality to the full extent, cost-saving and guarantee component lightweight.
The object of this invention is to provide a kind of MULTILAYER COMPOSITE rack sound barrier, this MULTILAYER COMPOSITE rack sound barrier is MULTILAYER COMPOSITE stereochemical structure, comprise the surface course being positioned at MULTILAYER COMPOSITE rack sound barrier both side surface, multiple middle soundproof course between surface course, between surface course and middle soundproof course and/or fill the light sandwich layer in space between middle soundproof course, surface course and middle soundproof course use sound insulating material or composite sound-insulation material to make, light sandwich layer uses sound absorption material to make, it is characterized in that: also comprise keel, keel between surface course and middle soundproof course and between middle soundproof course and connection table surface layer and middle soundproof course be connected in the middle of soundproof course form three-dimensional grid structure, and the extended line being positioned at the keel of same middle soundproof course side and the keel of this middle soundproof course opposite side does not overlap.
Preferably, on the length direction of compound rack sound barrier, keel are non-continuous print.The discontinuous setting of keel, can reduce structure-borne sound transmission, saves the use of spine material, saves cost, but also can alleviate the quality of sheet material self, make sheet material lightweight more, reduces the weight of structure.
Preferably, middle soundproof course is dull and stereotyped and corrugated sheet, and corrugated sheet has crest and trough.Use corrugated sheet to be the special design targetedly taked for the propagation characteristic of sound wave as middle soundproof course, effectively can prevent the acoustic short circuit under CF, reduce sound wave through, strengthen sound insulation property.
Preferably, compound rack sound barrier also comprises braced structures, on the strip width direction of described braced structures in surface course with middle soundproof course and keel arranged in a crossed manner.Increase after braced structures, the intensity of compound rack sound barrier is increased, and decrease the possibility that sheet material ruptures in the longitudinal direction.
Preferably, surface course, middle soundproof course and keel material used is silicate material or gypsum material or metal material or macromolecular material or their combination, and light sandwich layer material used is porous absorption material or fiber cotton like sound absorption material or expanding material.
Another object of the present invention is to provide a kind of application of MULTILAYER COMPOSITE rack sound barrier, and this MULTILAYER COMPOSITE rack sound barrier is applied in construction wall, mechanical cover and outer cover, automobile body, airframe and boats and ships peripheral structure and cabin separation structure.
MULTILAYER COMPOSITE rack sound barrier provided by the invention, at least one deck soundproof course is added separately between both side surface layer, and the light sandwich layer that filling sucting sound material is made, adds keel and substantially increases structural strength after jointly forming three-dimensional grid structure with middle soundproof course and surface course.This design has excellent sound insulation property, also has good heat-insulating property simultaneously, simple and reasonable, intensity is high, quality is light, volume is thin, fire prevention, environmental protection, easy to install, manufacturing process is simple, and cost is low.
Other features and advantages of the present invention are described in detail in detailed description of the invention part subsequently.
