Description
Technical field
The utility model belongs to building vibration damping sound insulation field, and in particular to a kind of light-weight aggregate acoustical insulation floor structure.
Background technology
Noise pollution is one of four overall situation pollution (air pollution, water pollution, rubbish, noise), according to statistics, ring
During all kinds of environmental pollutions of guarantor department processing are complained, the complaint to noise pollution holds pride of place, and accounts for the half of letter sum, its
The middle overwhelming majority be resident to its room by Intra-cell steady noise source (such as underground garage, pump house, elevator(lift) machine room, air-conditioning,
Become power distribution room, the cell public buildings such as ventilating system) noise jamming it is discontented.
《Code for design of dwelling houses》（GB50096）It is required that divide the air-borne sound sound insulation property air-borne sound sound insulation property Rw+C of family floor
>=45dB, separation house and non-domestic use divide family floor air-borne sound sound insulation property Rw+C >=51dB." 3A " high request is lived
The identification of residence performance, then require that the air-borne sound of Separate Home floor is satisfied by requiring with acoustic pressure is hit, floor especially set out is hit
Hit acoustic pressure and be not preferably greater than 65dB.
Although the sound insulation index of point family floor has regulation in specification, in design, construction, management link, but lack skill
The support of art aspect, the technology linking and supporting support of the design and construction that particularly insulates against sound, causes the confusion of following noise, but difficult
In the predicament for improving optimization.
As developer is supplied to the house of resident family, using reinforced concrete floor, the shock acoustic pressure of floor is typically in 80dB
Left and right, index request≤65dB in Code for design of dwelling houses is exceeded.Therefore, if not taking sound insulation measure, in general floor
Hit all difficult strike note pressure request for meeting high request and living of acoustic pressure.
Utility model content
Part in order to overcome the above-mentioned deficiencies of the prior art, the utility model provide a kind of light-weight aggregate acoustical insulation floor structure.
The utility model is achieved by the following technical solution：A kind of light-weight aggregate acoustical insulation floor structure, including concrete
Floor, described concrete floor upper surface are sequentially provided with sound insulation mortar, light aggregate bed course, adhesive mortar and built from the bottom to top
Build floor tile.
Described concrete floor is cast-in-place or prefabricated reinforced concrete floor, it is desirable to which floor quality density is not less than
300kg/m2, surfacing, hair is manually drawn and attenuated before hardening.
Described sound insulation mortar is by the soft particle of oak, water reducer, river sand, water-loss reducer, foam polyphenyl particle, cement, poly- third
Olefin(e) acid ester forms, and sound insulation mortar thickness is not less than 25mm.
Described light aggregate bed course is light concrete, and density is 650~800kg/m3, compression strength is not less than
2.0MPa。
Described light aggregate bed course density of per unit area on sound insulation mortar is no more than 80kg/m2, light aggregate
The thickness of bed course is no more than 100mm.
Described adhesive mortar is embedded with crack grid cloth.
The beneficial effects of the utility model are：Above-mentioned technical proposal has to the noise of noise-sensitive structure point family floor
Good improvement.By setting sound insulation mortar and light aggregate bed course, the mass density and thickness of extra play can be effectively reduced
Degree, floor crashing pressure are preferably improved.
Brief description of the drawings
Fig. 1 is the utility model structure diagram；
In figure, 1, concrete floor, 2, sound insulation mortar, 3, light aggregate bed course, 4, crack grid cloth, 5, adhesive mortar,
6th, floor tile is built.
Embodiment
The utility model is further illustrated below according to drawings and examples.
As shown in figure 1, a kind of light-weight aggregate acoustical insulation floor structure, including concrete floor 1, on described concrete floor 1
Surface is sequentially provided with sound insulation mortar 2, light aggregate bed course 3, adhesive mortar 5 and building floor tile 6 from the bottom to top.The utility model is adopted
Sound insulation is carried out with sound insulation mortar 2 and light aggregate bed course 3, effect is more obvious, and floor is hit by testing the utility model
Hit acoustic pressure improvement amount and be more than 15dB.
Concrete floor 1 described in the utility model is cast-in-place or prefabricated reinforced concrete floor, in order to ensure entirely to tie
The stability of structure, it is desirable to which floor quality density is not less than 300kg/m2, surface is smooth, is drawn in concrete hardening advance pedestrian work
Fine, soft fur processing, so it is easy to form an entirety with sound insulation mortar 2.
Described sound insulation mortar 2 is by the soft particle of oak, water reducer, river sand, water-loss reducer, foam polyphenyl particle, cement, poly- third
Olefin(e) acid ester forms, and for effectively sound insulation, the thickness of described sound insulation mortar 2 is not less than 25mm, and the weighted sound insulation of sound insulation mortar 2 changes
Kind amount is not less than 16dB, requires to accomplish closely knit imporosity or gap when mortar 2 is insulated against sound in laying.
Described light aggregate bed course 3 is using the lighter light concrete of density, it is desirable to the density of light concrete
For 650~800kg/m3, and compression strength is not less than 2.0MPa.
In order to mitigate the load to 2 layers of the mortar that insulates against sound, described light aggregate bed course 3 per unit face on sound insulation mortar 2
Long-pending density is no more than 80kg/m2, the thickness of light aggregate bed course 3 is no more than 100mm.
Adhesive mortar 5 used in the utility model is to be equipped with multiple additives by cement, quartz sand, polymer latex ramming material
A kind of mortar uniformly formed through mechanical mixture, it can firmly bond light aggregate bed course 3 and building floor tile 6, and this practicality
It is new that the crack grid cloth 4 for preventing crackle is also embedded with adhesive mortar 5.
In construction, floor is formed according to design requirement by reinforced concrete cast-in-situ, it is desirable to ensures that slab surfaces are put down
It is whole, draw and attenuate hair processing in concrete hardening advance pedestrian work；After entirely being hardened Deng floor, continue applying for 2 layers of mortar of sound insulation
Work, require to accomplish closely knit imporosity or gap when mortar 2 is insulated against sound in laying.After the 2 layers of hardening of sound insulation mortar, lightweight concrete is laid
Soil layer, the density of laying are no more than 80kg/m2, thickness is no more than 100mm.After lightweight concrete layer hardening, binding sand is used
Slurry 5 posts building floor tile 6.
