Description
Technical field
This utility model relates to sound insulating material defening effect measuring technology, concrete open a kind of floor
Sound insulationg board defening effect test device.
Background technology
Modern architecture strengthens upper and lower floor gap sound insulation effect by laying sound insulationg board on floor face
Really, country's standard to modern architecture defening effect is met；But sound insulationg board material has difference,
Cause defening effect variant, further result in the acceptance of work the most up to standard, cause serious commercial to damage
Lose；For solving this problem, needing test sound insulationg board defening effect in advance, existing sound insulationg board insulates against sound
Effect mainly completes test by test instrunment, and test instrunment production cost is high, and cost is up to
Millions of the most several ten million, and needed for sample presentation test, sample takes up space excessive, it has not been convenient to transfer
Transport.
Utility model content
Goal of the invention of the present utility model is: provide a kind of simple in construction for solving problem above,
Easy to operate, practical, cheap floor sound insulationg board defening effect test device.
This utility model be employed technical scheme comprise that such:
A kind of floor sound insulationg board defening effect test device, including simulation building Rotating fields, sound insulation sample
Plate, reference tapping machine and sound receiver, described simulation building Rotating fields top is for being used for placing
The concrete floor structure sheaf of sound insulation model and lower floor are that brick is piled up, for placing sound reception
The engraved structure of device；Described reference tapping machine is used for tapping sound insulation model sounding, and sound receives
Device receives acoustical signal and changes output intensity of sound.
Further, described floor construction layer is square, and the length of side is 1～2m；Described sound insulation sample

Further, corresponding described tester's standing platform position is provided with cat ladder.
In sum, owing to using technique scheme, the beneficial effects of the utility model are:
This utility model uses joining of simulation building Rotating fields, reference tapping machine and sound receiver
Close realize to sound insulationg board defening effect test, simple in construction, easy to operate, test effect have
The most thousand of pieces of comparability, cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
It is described in further detail of the present utility model with embodiment below in conjunction with the accompanying drawings.
As it is shown in figure 1, a kind of floor sound insulationg board defening effect test device, including simulation floor
Structure 1, sound insulation model 2, reference tapping machine 3 and sound receiver 4,
Described simulation building Rotating fields 1: top is for placing the sound insulation model 2 that the length of side is 1m
Concrete floor structure sheaf 11, this floor construction layer 11 is square, and the length of side is 2m；Lower floor
That pile up for brick, for placing the engraved structure 12 of sound receiver 4；Described sound connects
Adjustable (generally distance 1m, the sound of distance between receiving apparatus 4 and floor construction layer 11 downside
Maximum of intensity reference value is 65dB).
Described sound receiver 4 includes measuring microphone and preamplifier, it is ensured that test knot
Structure is reliable.
Extend tester standing platform 5 coplanar with described floor construction layer 1, corresponding described
Tester's standing platform 5 position is provided with cat ladder 6.
Described reference tapping machine 3 is used for tapping sound insulation model 2 sounding, and sound receiver receives
4 acoustical signals also change output intensity of sound.
During test, the sound insulation model 2 completed in advance is carried to simulation building Rotating fields 1 and pushes up
Portion, opens sound receiver 4 relevant device such as grade, and tester taps sound insulation model 2, sound
Sound receives device 4 and receives acoustical signal, and wherein intensity of sound maximum is reference value, by right
Than judging that sound insulation model 2 defening effect is the most up to standard.
Know-why of the present utility model is described above in association with specific embodiment.These only describe
It is to explain principle of the present utility model, and can not be construed to this practicality new by any way
The restriction of type protection domain.Based on explanation herein, those skilled in the art need not pay
Performing creative labour can associate other detailed description of the invention of the present utility model, these modes
Within falling within protection domain of the present utility model.
