Abstract

The utility model belongs to the damping sound insulation wall body that propagated in architectural acoustics field, the effective separation low -frequency noise of in particular to ability. This damping sound insulation wall body is formed through side interconnect by a plurality of wall body board unit, wall body board unit comprises surface course, laminboard layer and damping sound insulation board, wall body board unit surface course is the calcium silicate board layer, the laminboard layer of wall body board unit mixes the packing by cement mortar and foam granule and forms, the damping sound insulation board is respectively by gypsum board or cement fibrolite plate, flexible glue or asphalt felt or sound insulation felt and compound the forming of glass magnesium board three -layer sound insulation damping material. The thickness of damping sound insulation board is the density >= 15kgm2 of 16 -20mm, damping sound insulation board. It has characteristics such as the quality is light, intensity is high, the damping is good, low frequency sound insulation property is good, can be used as wall body (like KTV, bar, the nightclub etc. ) in the region that low frequency sound insulation had relatively high expectations.

Description

Damping sound-insulation wall
Technical field
The utility model relates to a kind of damping sound-insulation wall.
Background technology
Require that higher region (as KTV, bar, night club etc.) often needs selection effectively can intercept low-frequency noise and propagates at some sound insulation room, again can integral construction, the convenient materials for wall installed, and the common materials for wall in existing market or even sound insulating material are all made up of hard material, the defening effect for low-frequency noise does not have flexible material (as flexible glue, asphalt felt, sound-insulating felt etc.) so obvious yet;
The damping sound insulating material that existing market has is mainly damping sound-insulation board, as a kind of damping sound-insulation board that Chinese patent CN202248659U provides, comprises and being formed by gypsum plank, flexible inorganic Silica hydrogel, calcium silicate board Material cladding.This utility model damping is good, but its shortcoming is homogenous material, directly can not use as wall body structure construction material, must combinationally use with other structures (as lightgage steel joist, gypsum plank, glass wool etc.).But often have strict demand to construction speed etc. in Practical Project, can not be used for the damping sound-insulation board that body of wall builds material will increase construction volume, waste time and energy.
Heat insulating and sound insulating body of wall disclosed in Chinese patent literature CN204001398, have that quality is light, intensity is high, shock resistance, nail hang that power is strong, waterproof and dampproof, insulation, feature that sound insulation property is good, but still exist and directly can not use as wall body structure construction material.
In order to accelerate Construction Schedule, market is thirsted for one and effectively can be intercepted low-frequency noise and propagate, again can the overall damping sound-insulation wall used as materials for wall, becomes the research direction of numerous construction work and acoustics engineers and technicians.
Utility model content
In order to overcome existing materials for wall for defects such as sound insulation room quantity not sufficients, the utility model provides the damping sound-insulation wall that a kind of quality is light, intensity is high, damping is good, sound insulation room performance is good.
In order to solve the problem, the utility model is achieved through the following technical solutions
A kind of damping sound-insulation wall, to be interconnected by side by several ash wall body plate unit and to form, described ash wall body plate unit is by surface layer, laminboard layer and soundproof course composition, described surface layer is calcium silicate board, described laminboard layer mixes the foamed cement screed of filling by cement mortar and foam beads, it is characterized in that: described soundproof course is the damping sound-insulation board be composited by three layers of sound insulation damping material, wherein the first sound insulation Damping material layer is gypsum plank or cement fibrolite plate, second sound insulation Damping material layer is flexible offset plate or asphalt felt or sound-insulating felt, 3rd sound insulation Damping material layer is glass magnesium plate.
The thickness of described damping sound-insulation board is 16-20mm, the density>=15kg/m of damping sound-insulation board 2.
Described damping sound-insulation board is followed successively by the first sound insulation Damping material layer, the second sound insulation Damping material layer, the 3rd sound insulation Damping material layer from top to bottom.
Described damping sound-insulation wall is followed successively by surface layer, laminboard layer, soundproof course, laminboard layer, surface layer from top to bottom.
Described ash wall body plate unit is connected by side concave-convex member, and described concave-convex member is made up of trapezoidal projection and trapezoidal groove.
The damping sound-insulation wall that the utility model provides compared to existing technology, has following beneficial effect:
1, superpower damping capacity: general materials for wall is rigid material composition, even be made up of multiple unlike material, its damping capacity is also not obvious, thus causes its effect when intercepting low-frequency noise (especially below 250Hz frequency range) greatly to reduce.But the utility model considers that flexible material (as flexible glue, asphalt felt, sound-insulating felt etc.) is for the effect intercepting low-frequency noise, thus is provided with damping layer therein, effectively prevent the defect of sound insulation room.
2, superpower globality: some common damping materials are single often, directly can not use as body of wall, must combinationally use with other structures (as lightgage steel joist, gypsum plank, glass wool etc.).But can use as body of wall separately after the splicing of the utility model polylith unit board, there is the advantages such as simple installation is quick.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and embodiment, the utility model is further illustrated.
Fig. 1 is section splicing structure figure of the present utility model.
Wherein: 1. damping sound-insulation wall, 2. calcium silicate board, 3. sandwich of layers, 4. damping sound-insulation board, 5. tongue and groove, 6. the first sound insulation Damping material layer, 7. the second sound insulation Damping material layer, 8. the 3rd sound insulation Damping material layer.
