Abstract
The utility model discloses a wall absorber. The wall absorber is composed of an n-shaped elastic vibration reduction piece and an elastic structural plate. The n-shaped elastic vibration reduction piece is composed of an n-shaped steel plate and outer wrapping elastic rubber, and the two edges of the n-shaped elastic vibration reduction piece are provided with installation wings. The elastic structural plate is integrally formed by stamping an elastic steel plate, and is composed of a combination bottom plate, an elastic member and an installation member. The combination bottom plate is provided with a transverse convex part, and the combination bottom plate is inserted into the side face of the n-shaped elastic vibration reduction piece and wrapped by the elastic rubber. An installation plate is arranged on the side face of the elastic member, and provided with a vertical concave part and a self-drilling screw installation hole. The sound reduction index of a light structural wall can be effectively improved, construction is convenient, and the structure is simple.
Description
Technical field
The utility model relates to a kind of noise control technique field, especially can effectively intercept the body of wall shock absorber of Vibration propagation.
Background technology
Current, noise has become a kind of main environment pollution, and the acoustic environment problem of building is more and more subject to people's concern and attention.Selecting suitable material to insulate against sound and processing is one of fundamental technics measure in building acoustics Control Engineering.Particularly, at the partition wall of curtain structure of high-rise building, due to building structure bearing load and land resources saving, do not allow to use solid brick wall.At present, widely used is the compound partition wall of thin plate, and two of lightgage steel joists, each directly installs thin plate, and centre adds mineral wool sound absorption board.But, because lightgage steel joist is directly installed in building structure, between lightgage steel joist and building structure, form and be firmly connected, thereby produce thus the raising that overhead speaker has hindered the compound Sound insulation for partition amount of thin plate.
Summary of the invention
In order to overcome the deficiency of the lightgage steel joist of the compound partition wall of existing thin plate and the sound insulation factor decline that the rigid connection between building structure causes, the utility model provides a kind of body of wall shock absorber, this body of wall shock absorber is not only avoided the compound partition wall overhead speaker of thin plate, can improve the sound insulation factor of light structures body of wall, and easy construction, simple in structure.
The utility model solves the technical scheme that its technical problem adopts: a kind of body of wall shock absorber, is comprised of a few shape elastic damping parts, elastic construction plate; Described a few shape elastic damping parts are comprised of a few shape steel plates and outer cladding elastic caoutchouc, and two limits arrange the installation wing; Described elastic construction plate is one-body molded by spring steel plate punching press, binding base plate, elastic component, installation component, consists of.On described binding base plate, have horizontal convex, binding base plate inserts a few shape elastic damping parts side, is coated in elastic caoutchouc; Described installing plate is arranged on the side of elastic component, and vertical spill and self-drilling screw installing hole are set on installing plate.Described elastic construction plate two sides arrange the installation wing, install on the wing expansion bolt installing hole is set.
On binding base plate, there is horizontal convex, can improve the bond strength of binding base plate and a few shape elastic damping parts, effectively prevent that fixed head and a few shape elastic damping part from departing from.A few shape steel plates are coated elastic caoutchouc, can prevent metal erosion, improve weatherability, improve the useful load of body of wall shock absorber.
Vertical spill and self-drilling screw installing hole are set on installing plate, can improve the installation strength of installing plate and keel, and improve installation effectiveness.Installing plate is arranged on the side of elastic component, effectively bring into play the attenuation of elastic component to positive low frequency vibration, the feature of the elastomeric material of a few shape elastic damping of binding base plate part is to have interior friction, and critical damping is larger, can absorbing high-frequency vibrational energy, decay, intercept vibration and transmit.
Mounting means: one, use expansion bolt that body of wall shock absorber is arranged in building structure, the keel of light structures body of wall fixedly mount by installation component, and Light trabs is arranged on lightgage steel joist.Light trabs is subject to the vibration of sound wave to be passed to elastic component, the elastic component low frequency vibration that can decay, and a few shape elastic damping part energy attenuate high frequency vibrational energies, decay, intercept vibration and transmit.It is low that body of wall shock absorber has intrinsic frequency under nominal load, the feature that vibration isolating effect is good.
Two, original wall body is had to certain sound insulation function but the situation of sound insulation factor deficiency.Body of wall shock absorber can be arranged on original wall body, keel installation is on body of wall shock absorber, and keel directly do not link with original body of wall, to reducing overhead speaker, to improve sound insulation factor effect remarkable.
The beneficial effects of the utility model are effectively to improve the sound insulation factor of the compound partition wall of thin plate, and meanwhile, weatherability is good, simple in structure, cheap, convenient and quick construction.
