Abstract
A muting room sound proof window is formed by an outer sound proof structure and an inner sound proof structure. Laminated glass with different installation angles is arranged in each sound proof structure, and each piece of the laminated glass is formed by lamination of two pieces of glass with different thickness. The sound proof structures are formed by steel plate frames, outer laminated glass, and inner laminated glass, and the laminated glass is embedded in the steel plate frames through elastic rubber pressing strips. Elastic acoustic boards are installed between the inner laminated glass and the elastic rubber pressing strips of the outer laminated glass, and drying agents are filled in the elastic acoustic boards. The steel plate frames of the outer sound proof structure are installed on an outer wall body of a muting room, the steel plates frames of the inner sound proof structure are installed on an inner wall body of the muting room, and the elastic acoustic boards filled with the drying agents are installed between the outer sound proof structure and the inner sound proof structure. According to the muting room sound proof window, acoustic bridge phenomena, resonance effects and coincidence effects can be eliminated, and sound reduction index is high.
Description
Technical field
The utility model relates to a kind of noise control technique field, especially possesses the quiet room sound proof window of high sound insulation factor.
Background technology
Quiet room is a kind of sound insulation testing arrangement for product manufacturing shop design that test request is arranged, can test some small-sized products in the inside, quiet room, like motor, sound equipment, transformer etc.The key technology in quiet room and the key technical indexes are high sound insulation factors, make in the quiet room to reach low noise environment, and quiet atrial septum volume is high more, and the noise figure in the quiet room is low more, and the test effect is good more.Sound proof window is the main member of quiet room space enclosing structure, and its main effect is daylighting, observation, sound insulation.Because going along with sb. to guard him in the sound insulating structure of quiet room, sound proof window is more frivolous owing to comparing body of wall, the sound wave coincidence effect of glass, resonance low ebb property have caused the poor efficiency of sound insulation, are the weak links of sound insulating structure.So it is most important for the sound insulation factor that improves quiet room to improve the sound insulation factor of sound proof window.The sound insulation factor of sound proof window system is according to the standard of HJ/T 17-1966 sound proof window at present; According to: technical requirements 3.1.2 sound proof window performance rate; Weighted transmission loss Rw is by V level Rw, and >=25dB is to I level Rw, >=45dB; Even reach the I grade standard, still can not satisfy the requirement of the quiet atrial septum volume of part.
Improve constantly along with what the sound insulation to quiet room required, be badly in need of having the high quiet room sound proof window of a kind of sound insulation factor.
Summary of the invention
In order to improve the sound insulation factor of quiet room sound proof window; The utility model provides a kind of quiet room sound proof window; This quiet room sound proof window by two independently sound insulating structure form; Each sound insulating structure is provided with two different doubling glass of setting angle, and every doubling glass is formed by the glass doubling of two different-thickness.
The utility model solves the technical scheme that its technical problem adopted:
A kind of quiet room sound proof window is made up of outer sound insulating structure, interior sound insulating structure jointly, and each sound insulating structure is provided with the different doubling glass of setting angle, and every doubling glass is formed by the glass doubling of two different-thickness.Thickness of glass is different, avoids the resonance low ebb property of glass.Controlled " coincidence effect " effectively and formed the sound insulation low ebb, so that the frequency of the sound wave coincidence effect that staggers.Outer sound insulating structure, interior sound insulating structure reach outer doubling glass, interior doubling glass composition by the steel plate frame; Interior doubling glass uses A thickness glass, B thickness glass doubling to form; Outer doubling glass uses C thickness glass, D thickness glass doubling to form, and interior doubling glass, outer doubling glass all use the elastic caoutchouc press strip to be embedded in the steel plate frame.Avoid the overhead speaker phenomenon to prevent the vibration transmission of doubling glass.The outer doubling glass of outer sound insulating structure is installed in steel plate frame outer rim; The vertical oblique angle of interior doubling glass and steel plate frame is installed; The interior doubling glass of interior sound insulating structure is installed in steel plate frame outer rim; The horizontal oblique angle of interior doubling glass and steel plate frame is installed, and the minimum range between interior doubling glass and the outer doubling glass is not less than 50mm.Interior doubling glass, outer doubling glass setting angle difference make noise in interior doubling glass and outer doubling glass, repeatedly reflect and absorb, and weaken resonance effects, the raising sound insulation factor.Certain thickness air layer can present the effect of preferable air spring.The elasticity acoustical board is installed between the elastic caoutchouc press strip of interior doubling glass and outer doubling glass, and the elasticity acoustical board is parallel with the steel plate frame, between the filling desiccant.Sound wave in the sound absorbing capabilities of elasticity acoustical board can absorb and get between doubling glass and the outer doubling glass improves sound insulation factor, prevents to produce the overhead speaker phenomenon simultaneously, and the filling desiccant is to prevent the water smoke that humidity produces and the light transmission that hinders sound proof window.
The steel plate frame of outer sound insulating structure is installed on the outer body of wall in quiet room; The outer doubling glass of outer sound insulating structure is parallel with the outer body of wall in quiet room; The steel plate frame of interior sound insulating structure is installed on the interior body of wall in quiet room, and the interior doubling glass of interior sound insulating structure is parallel with the interior body of wall in quiet room.Parallel elasticity acoustical board, elasticity acoustical board down, the filling desiccant between last elasticity acoustical board and the following elasticity acoustical board installed between outer sound insulating structure and the interior sound insulating structure.
If because the thickness of wall body in quiet room is less, outer sound insulating structure can be arranged to be made up of steel plate frame and outer doubling glass.
The beneficial effect of the utility model is,Use compound suction, at a distance from structure, stop overhead speaker phenomenon, resonance effects and coincidence effect, sound insulation factor is high, satisfies at present the sound insulation requirement in strict quiet room.
