Description
Technical field
The utility model belongs to building acoustics field, particularly not only energy-saving heat preserving but also can effectively intercept the airborne heat insulating and sound insulating body of wall of noise of one.
Background technology
Due to the reason of building structure bearing load, under more susceptible condition, only allow to arrange light partition wall, the light sound-proof wall plate that existing market has is mainly calcium silicates composite laminboard, as open in Chinese patent CN201671217U(day is on 12. 15th, 2010), a kind of novel light fireproofing energy-saving assembled wall is provided, comprise by calcium silicate board substrate and swollen account pearl rock stratum or foam concrete layer and forming, be clipped in and between two calcium silicate board substrates, have expanded pearlite rock stratum or foam concrete layer, the mutual bonding formation building assembling wallboard of described calcium silicate board substrate and expanded pearlite rock stratum or foam concrete layer.The gross thickness of building assembling wallboard is 20mm-500mm, and the thickness of described every one deck calcium silicate board substrate is 4mm-60mm.This utility model high insulating effect, but its shortcoming is that sound insulation is undesirable, the calcium silicates compound sandwich board wall sound insulation factor that for example 100mm is thick only has 40dB left and right, can only reach by the thickness that increases wallboard for increasing sound insulation factor, but often partition wall is had to load-bearing requirement in Practical Project, and the space availability ratio problem in some regions also causes increasing wallboard thickness, therefore increase as seen wallboard thickness and be not the Perfected process that increases sound insulation factor.
The region (as hotel guest room, household bedroom, hospital ward, business office, public place of entertainment etc.) of having relatively high expectations in some sound insulation often needs to select not only light thermal-insulation but also the good novel wall material of defening effect.Therefore how to design both light energy-saving thermal preservations, can improve again the sound-insulation wall of defening effect, become numerous construction works and acoustics engineers and technicians' research direction.
Summary of the invention
In order to overcome the defect such as sound insulation factor deficiency of existing calcium silicates composite laminboard, the utility model provides that a kind of quality is light, intensity is high, shock resistance, nail hang that power is strong, waterproof and dampproof, insulation, heat insulating and sound insulating body of wall that sound insulation property is good.
In order to address the above problem, the utility model is achieved through the following technical solutions:
A kind of heat insulating and sound insulating body of wall; interconnect and form by side by several ash wall body plate unit; it is characterized in that: described ash wall body plate unit by surface layer, laminboard layer and at least the soundproof course of one deck form; described ash wall body plate unit surface layer is calcium silicates flaggy; the laminboard layer of described ash wall body plate unit mixes filling by cement mortar and foam beads and forms; described soundproof course is calcium silicate board or cement fibrolite plate; soundproof course is clipped between two laminboard layers; soundproof course thickness is 6-12mm, the density>=1.2kg/m of soundproof course
2.
Further, described ash wall body plate unit soundproof course is placed in the middle of occupying body of wall.
In the time that described ash wall body plate element thickness is 100mm, its sound insulation property >=45dB.
Consider that between wall panel element, a kind of good structure of sound insulation property is that described side, ash wall body plate unit interconnects the connection of employing tongue and groove.
The heat insulating and sound insulating body of wall that the utility model provides is compared the technology of enjoying, and has following beneficial effect:
1, good fireproof performance, calcium silicate board and cement fibrolite plate are all A level incombustible materials, and foamed cement screed is also A level incombustible material, and this heat insulating and sound insulating body of wall is by the flammability test of " NFA equipment Quality Surveillance inspection center ".
2, superpower sound insulation property, general calcium silicates composite laminboard needs metope perforate (as switch hole, socket aperture, wire casing etc.) when mounted, body of wall surface layer is destroyed, thereby cause the reduction of sound insulation property.But after the utility model perforate, the calcium silicate board of soundproof course or cement fibrolite plate still keep complete, so negligible on the impact of defening effect.Facts have proved the thick heat insulating and sound insulating body of wall of 100mm, its sound insulation property is equivalent to the aerated concrete wall that 300mm is thick, or 200mm calcium silicates compound sandwich board wall.The thick heat insulating and sound insulating body of wall of 100mm of the present utility model is according to " measurement of GB/T19889.3-2005 building unit air borne sound sound insulation testing room " standard by " acoustic investigation institute of Tongji University " test, and sound insulation factor is 45dB.Therefore ash wall body plate of the present utility model is the optimal selection of current building wall sound insulation.
3, quality is light, density is little, in inner wall of building, use ash wall body plate of the present utility model, can make building deadweight reduce more than 30%, as considered ash wall body plate of the present utility model in the design stage, can greatly reduce fabric structure and foundation cost, and can optimize post and beam structure, make indoor arrangement more reasonable.
