Abstract
The utility model provides a sound insulating pad for a floating floor slab. The sound insulating pad is used for reducing the impact sound pressure level of the building floor slab and improving the sound insulating effect of the floor slab. The technical proposal of the utility model is as follows: the sound insulating pad is formed by sticking multilayer (more than two layers) flexible obturator foramen elastic foaming materials with different densities or different materials. The sound insulating pad improves the damping property of the sound insulating pad for the floating floor slab through the change in the density or material of different layers, reduces the impact sound pressure level of the building floor slab within the narrow frequency range, and has better sound insulating effect than the single layer material with the same material and the same thickness. The sound insulating pad for the floating floor slab adopts the obturator foramen elastic foaming material which has waterproof and dampproof functions, has simple construction process and high construction speed and has the comprehensive cost lower than the prior sound insulating pad for the floating floor slab. The sound insulating pad for the floating floor slab has a multilayer sticking structure and has better elasticity, compressive strength and durability than the single layer material with the same material and the same thickness.
Description
(1) technical field
The utility model relates to a kind of sound isolation of floor material for building, arbitrarily downgrades and makes building floor have good soundproof effect thereby be used to reduce the floor impact sound.
(2) background technology
The building noise comprises air and two kinds of forms of impact sound, and the noise major part of propagating by floor all is an impact sound.The impact sound of building mainly is that the collision of object and building unit makes it produce vibration, and vibration wave is along building structure is propagated and radiation in ambient air produced noise.In the buildings in general, floor is the main building unit that produces impact noise, and for example the collision of Switch for door and window, object drop, and ground, tables and chairs drag, knocking etc. of heel all can produce impact noise when child played and the people walks about on floor.
The scheme preferably that reduction floor impact sound is arbitrarily downgraded is to adopt the floating build floor structure, promptly lays one deck elasticity sound insulation bed course on structure floor, then concreting on elasticity sound insulation bed course.Traditional floating build floor sound insulation bed course generally adopts rock cotton board, block of glass wool, wood fiber slab and cane fiber board etc., but mouldy easily or lose the sound insulation function because of being compacted after this class material suction moisture absorption, must carry out the waterproofing work of strictness when therefore constructing.This class material is difficult to large-scale promotion application because of there being shortcomings such as construction technology complexity, cost height, soundproof effect be undesirable always.The someone attempts doing floating build floor sound insulation bed course with polyphenyl plate and individual layer 5 millimeters thick polyethylene foamss in recent years, and the result shows that the soundproof effect of polyphenyl plate is very not undesirable, and the slab thickness increase can cause the room floor height to reduce too much; Though and individual layer 5 millimeters thick polyethylene foams soundproof effects reluctantly can, its poor durability is built the layer of concrete compacting and is lost the sound insulation function by floating easily.
(3) summary of the invention
In order to overcome shortcomings such as traditional floating build floor sound insulation such as rock cotton board, block of glass wool, polyphenyl plate bed course cost height, construction complexity, soundproof effect difference, the utility model provides a kind of floating build floor sound insulating pad, this floating build floor sound insulating pad not only can reduce the floor impact sound significantly arbitrarily downgrades, and waterproof, thickness is little, construction is simple.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of floating build floor sound insulating pad is characterized in that: being fitted by the flexible closed cell flexible foaming material of multilayer (more than two-layer) different densities or unlike material forms.
Above-mentioned floating build floor sound insulating pad, the number of plies of described expanded material is two-layer at least, and the thickness that described expanded material is every layer is not less than 2 millimeters.
Above-mentioned floating build floor sound insulating pad, described expanded material are closed cell foamed material.
Above-mentioned floating build floor sound insulating pad, described expanded material are soft resilient expanded material.
Above-mentioned floating build floor sound insulating pad, described expanded material comprise chemical crosslinking polyethylene foamed (XPE), electronic crosslinking foaming polyethylene (IXPE), PE Foam (EPE), Ethylene Propylene Terpolymer (EPDM) foaming plate, rubber-plastic sponge (NBR/PVC), bipeltate plate etc.
Above-mentioned floating build floor sound insulating pad, described multi-layer foam material as well can be fitted by the expanded material of the identical material different densities of multilayer (different coefficient of foaming) and be formed.
Above-mentioned floating build floor sound insulating pad, described multi-layer foam material as well also can be fitted by the expanded material of multilayer unlike material and be formed.
The beneficial effects of the utility model are: the damping and amortization that increases this floating build floor sound insulating pad by the variation to density or material between the above-mentioned floating build floor sound insulating pad different layers, make this floating build floor sound insulating pad reduce the floor impact sound in wider frequency range and arbitrarily downgrade, soundproof effect is better than the monolayer material with the material stack pile; Above-mentioned floating build floor sound insulating pad adopts closed cell foamed material itself to have waterproof and dampproof function, and working procedure is simple, and speed of application is fast, thereby comprehensive cost is lower than traditional floating build floor sound insulation bed course; Above-mentioned floating build floor sound insulating pad adopts the lamination coating structure, and its elasticity, compressive strength, durability all are better than the monolayer material with the material stack pile.
