Adopt elastic connection and flexible contact to handle, solve structural vibration and structure -borne sound transmission problem. To completely cut off the structure -borne sound transmission transaudient with the air through setting up damping sound insulation board, acoustical absorption and sound insulation board, from a plurality of angles damping that insulates against sound comprehensively, can satisfy multiple functional requirement such as sound insulation, damping, decoration, fire prevention simultaneously.
Description
Technical field
The utility model relates to a kind of building floor sound insulation vibration damping ceiling structure, is applicable to building floor sound insulation vibration damping being had to higher environmental requirement.
Background technology
The floor project of Intercontinental Hotel, high request house, healthy residence, has higher acoustic environment index Design requirement to residence floorslab every sound and vibration.As in " Residential Building Estimate Information technical standard " (GB/T50362-2005), house combination property reaches " 3A " level, and the sound insulation property of floor and body of wall must reach requirement.Require that acoustic pressure≤65dB, air borne sound weighted transmission loss >=50dB are clashed in the standardization of floor weighted.The sound insulation of floor comprises the isolation performance to impact sound and air borne sound two kinds of sound, is one of key factor of guaranteed technology for acoustical environment.And for Intercontinental Hotel, similar president suite, higher to the requirement of floor sound insulation and vibration damping, as required floor STC >=55dB, NIC >=50dB.According to statistics and on-the-spot acoustics sample testing, if floor does not process, the impact sound of floor all can not reach the sound insulation requirement of house combination property 3A level mostly.
Existing floor sound insulation and vibration damping treatment technology, can be divided into two kinds according to disposal options, one can be implemented at floor end face, as adopted floating build floor mode; One can be implemented at soffit, as adopted the mode of furred ceiling.Past adopts furred ceiling way, more pays close attention to attractive in appearance with molding decorative effect, for the function of its sound insulation vibration damping, pay close attention to insufficient, in design and construction link, also lack the structure's practice, particularly detail of sound insulation vibration damping furred ceiling about sound insulation and the way of vibration damping.
Summary of the invention
In order to solve the defect that above-mentioned prior art exists, the utility model provides a kind of building floor sound insulation vibration damping ceiling structure, and can effectively insulate against sound vibration damping.
The technical solution adopted in the utility model: a kind of building floor sound insulation vibration damping ceiling structure, comprise multiple vibration reducing lifting hook, be connected with building top above described vibration reducing lifting hook, channel is connected below vibration reducing lifting hook, vibration damping sound barrier is installed below described channel, between described channel and vibration damping sound barrier, is provided with horizontal vibration damping pad; Sound absorption sound insulating panel is filled above described vibration damping sound barrier; Described vibration damping sound barrier adopts vertical cushion blocking to contact with periphery body of wall junction, and described vertical cushion blocking, body of wall, vibration damping sound barrier contact area are coated with one deck fireproof seal gum.
The beneficial effects of the utility model: adopt elasticity to connect and flexible contact process, solve structural vibration and structure-borne sound transmission problem.Vibration reducing lifting hook is set by furred ceiling, body of wall friendship circle place arranges vertical cushion blocking and channel and vibration damping sound barrier contact portion and arranges horizontal vibration damping pad to realize the abatement vibrated; By arranging vibration damping sound barrier, sound absorption sound insulating panel carrys out the transaudient and air-borne sound of isolation structures, to insulate against sound vibration damping comprehensively, can meet the multi-functional requirements such as sound insulation, vibration damping, decoration, fire prevention simultaneously from multiple angle.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Be below a specific embodiment of the present utility model, existing the utility model is described in further detail by reference to the accompanying drawings.
As shown in Figure 1, a kind of building floor sound insulation vibration damping ceiling structure, comprise multiple vibration reducing lifting hook 1, be connected with building top above described vibration reducing lifting hook, channel 2 is connected below vibration reducing lifting hook 1, below described channel 2, vibration damping sound barrier 3 is installed, between described channel 2 and vibration damping sound barrier 3, is provided with horizontal vibration damping pad 6; Sound absorption sound insulating panel 4 is filled above described vibration damping sound barrier 3; Described vibration damping sound barrier 3 and periphery body of wall hand over circle place to adopt vertical cushion blocking 7 to contact, and described vertical cushion blocking 7, body of wall, vibration damping sound barrier contact area are coated with one deck fireproof seal gum 5.
In the present embodiment, described sound insulation vibration reducing lifting hook, require that damping ratio is comparatively large and natural frequency is lower, load-bearing >=90kg, described channel 2 adopts 50 serial lightgage steel joists, installing space≤900mm.
Described vibration damping sound barrier 3 thickness is 17mm, weighted transmission loss R
wfor 37dB, fireproof performance A level, coefficient of thermal conductivity≤0.343W/ (MK).
Described sound absorption sound insulating panel 4 adopts thickness to be the block of glass wool of 50mm, mass density>=24kg/m
3, described sound absorption sound insulating panel 4 is highly identical with channel 2.
Described horizontal vibration damping pad 6 and the thickness of vertical cushion blocking 7 are 5mm, concordant with bottom vibration damping sound barrier 3 bottom vertical cushion blocking 7, top 5-10mm higher than vibration damping sound barrier 3, and horizontal vibration damping pad 6 and channel 2 contact edge every side extension are no less than 10mm.
Described fireproof seal gum 5 adopts flame resistant glass glue or rubber cement, and level, vertical sealing projected length are 5-8mm.
Certain Intercontinental Hotel's project, guest room floor is in-situ reinforced concrete slab, and thickness of slab is 140mm, requires floor sound insulation STC >=55dB, NIC >=50dB.The way of building floor sound insulation vibration damping ceiling structure is have employed in enforcement.Adopt above-mentioned sound insulation vibration damping ceiling structure way, survey this guest room, Intercontinental Hotel floor sound insulation factor and reach 53dB(R
