Description
Technical field：
The present invention relates to a kind of floor sound insulation brick, it belongs to building material technical field, and particularly a kind of floor sound insulation is used
Brick.
Background technology：
With the improvement of living standards, people also increasingly pay attention to the sound insulation property of building.The sound insulation property of building point
For air-borne sound oise insulation factor and strike note oise insulation factor.
The air-borne sound oise insulation factor of floor --- partiting sound member is set between the sound source of air-borne sound and receiving area, will necessarily be made
For the air-borne sound of receiving area by every falling a part, it is exactly oise insulation factor " every the decibels for falling sound ".Building is required in civil buildings
Plate has certain sound-insulation capability, it is therefore an objective to ensures the peace and quiet of indoor environment.Now, floor can be considered two rooms under upstairs house
Between partiting sound member, the air-borne sound that can effectively weaken two rooms interferes.Due to single layer structure partiting sound member every
Acoustic performance follows mass law of sound insulation, i.e. component is more thick and heavy, and sound insulation property is better, therefore thick and heavy concrete floor can expire easily
The requirement of sufficient air-borne sound sound insulation.
The strike note oise insulation factor of floor --- hit in two rooms that floor can be above and below floor and cause noise.Description is hit
The index for hitting the transaudient sound insulation property of sound is " shock sound pressure level ", it be different from expressed by air-borne sound oise insulation factor " every falling sound
Decibels ", but represent when hitting floor using reference tapping machine (a kind of equipment that can produce standardized impact energy), building
The size that the sound that plate is sent influences on (giving no thought to upstairs) downstairs.It is big to hit noise caused by the big expression floor of sound pressure level
And floor is small to the iris action of strike note in itself.It is small to hit sound pressure level, may have two kinds of origin causes of formation and both into therefore folding
Add effect：1) when reference tapping machine hits floor, caused noise is small in itself (such as has spread floor glue or applied flexible material for floor
The floor of material)；2) floor has good iris action to strike note in itself --- even if reference tapping machine produces when hitting floor
Very big noise is given birth to, but imperceptible noise is very big (such as floating build floor) downstairs.
For examining the parameter of strike note oise insulation factor to be：Sound pressure level is hit in weighted standardization.So-called weighted standardization is hit
It is the Rating of the single value method that International Organization for standardization suggests to hit sound pressure level.Sound pressure level frequency characteristic and state are hit into standardization
The monodrome index that reference curve as defined in the standardization body of border is read more afterwards by certain rule, referred to as weighted standardize strike note
Arbitrarily downgrade.By mankind's normal good hearing, when floor weighted hits sound level and is less than 65dB, in addition to beaing, jumping, in general sound is all
It can't hear；When weighted hits sound level in 75dB-85dB, it can hear sb's steps, drag tables and chairs sound, child to jump race sensation strongly,
Tap-tap is then more difficult to endure.
Decay very little of the energy of solid sound in traditional building material, spread speed is than fast in atmosphere, propagation distance
It is again far.Continuously, the air-borne sound defening effect of thick and heavy and hard concrete floor is good, but for the resistance of strike note (solid sound)
It is very poor every effect.So the resident family for staying in lower floor typically can't hear the voice of upper strata resident family, but upper strata resident family drag desk,
Child's race is jumped, the sound on heel percussion ground is very big on the influence of resident family of lower floor.The weighted standardization of ordinary residence concrete floor
Sound pressure level is hit about in 80dB or so, it is necessary to takes sound insulation measure to be possible to the requirement for reaching relevant criterion.Existing point of family
The weighted standardization of floor hits sound pressure level and is：Ordinary residence is not more than 75dB, and high request house is not more than 65dB.
To improve the sound insulation property of residence floorslab, carpet or laying elastic surface layer can be laid on slab in concrete structure
Material, or all kinds of floors of laying.But the measure taken when generally, above measure is all secondary decoration, implementation management portion
Door can not Qiang Zhiyaoqiu that owner takes these measures.In fact, most owners prefer to use tile floor.When handing over building with regard to energy
The way of acoustical insulation floor up to standard is mostly " floating to build method acoustical insulation floor ", and it employs professional sound insulating pad as elastic insert, in bullet
Property bed course above pour 50mm thickness two-way reinforcements pea gravel concreten and form the very thick of four-layer structure and floating build method acoustical insulation floor.Although
This " floating to build method acoustical insulation floor " strike note defening effect is fine, but involves great expense, and execution conditions are more harsh, and technique is multiple
It is miscellaneous, but also have compressed the use space of floor.It is unfavorable for promoting the use of.

A kind of atypical " floating to build method acoustical insulation floor ".It employs a kind of so-called " acoustic damping mortar " and substitutes professional sound insulating pad, and public
Open and how " acoustic damping mortar " to have been set to the method for arriving former professional acoustic pad position.It is characterized in the valency of acoustic damping mortar
Lattice are far below professional acoustic pad.The defects of technical scheme is to set " acoustic damping mortar " to former professional acoustic pad position
Spent man-hour is also very high apparently higher than man-hour, relative cost needed for professional acoustic pad is laid.With China labour
The increase of cost, the price advantage of the patent of invention have not existed.
