Selecting the sheet material of different thickness composition, its object mainly plays the reflex action to sound wave, avoids two laminate materials to produce resonance, avoids the appearance of coincidence effect. Thus effectively promote sound insulation property.
The excellent in performance carrying out a kind of metal sheet lightweight partition wall of limited checking the utility model from principle of design and experimental data two aspect is carried out below by specific embodiment.
The structure of a kind of metal sheet lightweight partition wall is: the thickness of outside plate layer 1 is 2.4mm, the thickness of sound insulation carpet veneer 2 is 6mm, it is made up of the sound-proof felt after two 3mm, keel select 75 type Lightgage Steel Joists (width is 75mm), the thickness of soft matter sound-absorbing material is 50mm, the thickness meeting insulating board layer 4 is 13mm, and the thickness of outside plate layer is 1mm.
Specific design principle:
Analyzing theoretically, affecting a kind of metal sheet lightweight Sound insulation for partition performance has following principal element:
First is mass law:
The definition of air-borne sound oise insulation factor isWherein �� is the ratio of transmission acoustic energy with incident acoustic energy, and unit is dB. Oise insulation factor can simply be interpreted as the difference of partition wall both sides sound decibel number.
The calculating formula of the oise insulation factor R of body of wall and floor is as shown in following formula in theory:
R=20lgm+20f-43
Wherein m is unit area quality, and f is sound frequency, and mass area ratio often doubles as can be seen from the above equation, and oise insulation factor can increase 6dB, and this is exactly mass law.
Being in the partition wall of substrate taking metal sheet, the metal sheet area density of substrate is inherently relatively big, and sound insulation sheet material has bigger area density, bond quality law especially, is that the lightweight wall of substrate has higher oise insulation factor because having higher area density taking metal sheet.
2nd is overhead speaker effect and coincidence effect:
The keel 3 and the both sides sheet material contact surface that use in metal sheet composite structure utilize sound insulation carpet veneer 2 and composite sound insulation board layer 4 to carry out vibration damping process, make sound wave at the vibration energy exciting keel 3 by sound wave by weakening during keel 3, effective reinforcing structure transmission loss, weakens overhead speaker effect.
It can be seen that two layers of identical sheet material superimposed after threshold frequency and the threshold frequency of single plate substantially equivalent, produce coincidence effect on this frequency; If the identical frequency of two laminates is identical, the synchronous superposition of vibration of two laminate materials can be caused so that identical paddy can be deepened. The resonant frequency of double wall is:
In formula, m1��m2It is the area density (kg/m of two layers of wall2); D is the air layer thickness (m) between two layers strong.
In the curtain wall structure of multiple layer metal plate structure and soundproofing lagging compound composition, the sheet metal thickness of both sides is different, and material difference (sound insulation carpet veneer 2 and composite sound insulation board layer 4), so just can avoid identical paddy effectively, and the raising of sound insulation property is favourable. At bilayer structure filling sucting sound material, can also can also improve the sound insulation property under resonant frequency and threshold frequency equally.

For now widely used lightweight body of wall, the lightweight partition wall thickness conventional to tradition and oise insulation factor are tested, and the lightweight Sound insulation for partition performance of test enters following table:
In GB50118 2010 " covil construction sound insulation design rule " and Beijing provincial standard DBJ01 618 200l " economic and suitable house standard ", regulation house party wall oise insulation factor should be not less than 50dB; As can be seen from the table, lightweight partition wall performance conventional at present can not meet related request, at the body of wall of 100mm left and right thickness, does not almost have the oise insulation factor that can reach more than 50db.
