Abstract
The utility model discloses a kind of damping sound insulation adding storey structure, relate to damping opacity technique field.The utility model comprises the composite intermediate layer be made up of with the reinforced concrete floor being laid on sound absorption buffer layer surface the sound absorption buffer layer be laid on floor surface, composite intermediate layer be provided with elastomeric isolation layer between the walls, the upper surface of composite intermediate layer is concordant with the upper surface of elastomeric isolation layer.Advantage: by arranging elastomeric isolation layer, sound absorption buffer layer and reinforced concrete floor, can obviously weaken step walk about sound, furniture moves sound, toilet draws water sound, Pipeline sound, confused noise, electric equipment sound etc. to the interference closing on room, sound insulation factor reaches 20 ~ 25dB (A).
Description
Technical field
The utility model relates to damping opacity technique field, and specifically a kind of damping sound insulation adding storey structure, is mainly used in centralized esidential building building, the floor damping sound insulation of the hotel of multilayer or highrise building, office premises and industrial premises etc.
Background technology
Known multilayer or highrise building, upstairs the step of personnel walk about sound, furniture moves sound, toilet draws water sound, Pipeline sound, the confused noise, electric equipment sound etc. of room, left and right personnel import indoor into through the hole of floor, wall, door and window and pipeline, have a strong impact on and disturb normal life and the work of indoor people.
Summary of the invention
The utility model provide a kind of damping insulate against sound adding storey structure, improve the damping sound insulation property of floor, weaken or
Block air borne sound and solid sonic propagation, reduce or eliminate the acoustic disturbance closing on room.
The utility model realizes with following technical scheme: a kind of damping sound insulation adding storey structure, comprise the composite intermediate layer be made up of with the reinforced concrete floor being laid on sound absorption buffer layer surface the sound absorption buffer layer be laid on floor surface, composite intermediate layer be provided with elastomeric isolation layer between the walls, the upper surface of composite intermediate layer is concordant with the upper surface of elastomeric isolation layer.
It is further: the thickness of described elastomeric isolation layer is 10 ~ 30mm; The height of sound absorption buffer layer is 30 ~ 50mm; The height of reinforced concrete floor is 30 ~ 50mm.
Described elastomeric isolation layer adopts elastic cushioning material to make, and described elastic cushioning material is rubber tile, bipeltate or foamed plastics.
Described sound absorption buffer layer adopts sound absorption material to make, and described sound absorption material is glass mat, mineral wool blanket or polyurethane foamed plastic.
The beneficial effects of the utility model are: by arranging elastomeric isolation layer, sound absorption buffer layer and reinforced concrete floor, can obviously weaken step walk about sound, furniture moves sound, toilet draws water sound, Pipeline sound, confused noise, electric equipment sound etc. are to the interference closing on room, and sound insulation factor reaches 20 ~ 25dB (A).
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1, elastomeric isolation layer, 2, sound absorption buffer layer, 3, reinforced concrete floor.
Detailed description of the invention
As shown in Figure 1, a kind of damping sound insulation adding storey structure comprises the composite intermediate layer be made up of with the reinforced concrete floor 3 being laid on sound absorption buffer layer 2 surface the sound absorption buffer layer 2 be laid on floor surface, composite intermediate layer be provided with elastomeric isolation layer 1 between the walls, the upper surface of composite intermediate layer is concordant with the upper surface of elastomeric isolation layer.
Should the specific implementation process of utility model as follows:
First, pasting thickness in the bottom of room surroundings wall is 10 ~ 30mm, the height elastomeric isolation layer contour with adding storey structure thickness (highly also can a little higher than adding storey structure, crop the part exceeding adding storey structure after construction terminates).Elastomeric material selects rubber tile, bipeltate, foamed plastics or high density sound absorption material etc.
Secondly, at the upper surface of existing floor, laying depth is the sound absorption buffer layer that 30 ~ 50mm sound absorption material makes.Sound absorption material Material selec-tion glass mat (density 100
left and right), mineral wool blanket (density 200
left and right) or polyurethane foamed plastic (density 50
left and right) etc.
Finally, on the sound absorption buffer layer laid, prick muscle fluid concrete and form reinforced concrete floor.The model of reinforcing bar, specification and concrete thickness, according to floor stressing conditions, are determined by calculating.
