Technical Field
The utility model relates to an assembly type structure technical field, concretely relates to amortization iron sheet equipment cavity.
Background
In the domestic urban construction continuous development, the land price and the room price are rapidly increased, the building density is increased due to the high-strength development, huge noise is generated in production and living, and serious noise pollution is caused to surrounding residential areas. Traditional sound insulation protective screen's main is to the wall setting sound insulation panel, carries out corresponding syllable-dividing measure to the door and window, has so not only increased house decoration cost, and the noise cancelling effect that gives sound insulation moreover is limited, especially to the noise of high frequency, and the penetrating power is strong, arouses people's mood unstability very easily, does not have effectual elimination means always, has caused the influence to resident's daily life work and rest.
In other serious disaster areas with noise pollution, such as factories, KTVs, music halls and the like, the sound insulation mode is still to add sound insulation plates for the wall body, and the noise pollution can not be effectively reduced. Therefore, the utility model provides a amortization iron sheet equipment cavity to solve the not enough of prior art.

Drawings
Fig. 1 is a schematic structural view of an assembly cavity of an acoustic sheet according to an embodiment of the present invention.
In the figure: 1-iron shell, 2-sound insulation layer, 3-reinforced hollow tube, 4-composite foam sound absorption layer and 5-central cavity.
Detailed Description
The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
Referring to fig. 1, the embodiment of the utility model provides a amortization iron sheet equipment cavity includes syntactic foam acoustic absorber 4, puigging 2 and iron shell 1 by interior and outer in proper order, wherein, is equipped with at least one enhancement hollow tube 3 in the puigging 2, is equipped with central cavity 5 in the syntactic foam acoustic absorber 4, and central cavity 5 is equipped with at least one toper chamber 6, and toper chamber 6 uses central cavity 5 to be radial equipartition as the center. The central cavity 5 is a cuboid or a round table, a cylinder, a sphere or a regular polyhedron.
The reinforced hollow pipe 3 reinforces the internal structural strength of the cavity and is internally provided with plastic sound insulation foam. The built-in plastic acoustic foam further dissipates acoustic energy.
The sound-insulating layer 2 consists of a rigid polyurethane open-cell foam. The hard polyurethane foam plastic is widely applied to various departments of national economy such as buildings, traffic and the like due to light weight, good heat insulation performance, excellent sound absorption and buffering shock resistance, higher compression strength, better dimensional stability, flexible processing mode, convenient molding construction and high curing speed.
The syntactic foam acoustic absorption layer 4 is composed of a soft polyurethane closed cell foam. The composite foam sound absorption layer is made of soft closed-cell foam materials, the soft closed-cell foam materials belong to polyurethane foam, and the polyurethane has the advantages of high sound absorption coefficient, low density, high elasticity, convenience in construction, low cost and the like.
The conical surfaces of the conical cavities 6 are distributed along the geometric center of the central cavity 5 in a divergent manner. The conical cavity 6 generates waveform transformation around the boundary of the conical cavity 6 in the process of propagation of sound waves, so that part of longitudinal waves are continuously converted into shear waves and other waveforms, and the loss of sound energy is increased; when the sound wave enters the central cavity 5, the central cavity 5 enables the incident sound wave to generate scattering, and simultaneously waveform transformation occurs, so that the transmission direction of partial sound wave is changed, the transmission distance of the sound wave in the composite foam sound absorption layer 4 is increased, and the components of shear wave are also increased, thereby more effectively consuming the energy of the incident sound wave.
The thickness of the iron shell 1 is 0.2-2.0 mm. The iron shell 1 cannot be too thick and too thin, and too thick increases material cost, and too thin reduces weight and strength on the one hand, and increases sheet processing cost on the other hand, but is not economical, so it is important to select an iron shell 1 with an appropriate sheet thickness.
The utility model provides an amortization iron sheet equipment cavity compares with prior art, and the application constitutes return circuit resonant structure with the communicating toper cavity of central cavity, has further widened the sound absorption bandwidth of noise elimination tile, promotes the high frequency sound absorption performance of noise elimination tile.
The utility model provides an amortization iron sheet equipment cavity is by multilayer material combination cavity, and the combination through stereoplasm and soft layer improves the low frequency sound absorption performance of noise elimination tile, has widened the sound absorption frequency band, and used material and technology are all comparatively ripe, can effective reduce cost through the integrative cold press shaping of bonding, reduce the degree of difficulty that the engineering was used.
The present invention is not limited to the above embodiments, and for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations are also considered to be within the protection scope of the present invention.
