The utility model is directly arranged on the keel or the wall surface, is modularly arranged, is simple and convenient, has low requirements on environment and structure, and has wide applicability.
Description
Technical Field
The utility model relates to the technical field of environmental protection, in particular to an integrated sound-absorbing wallboard.
Background
The noise emitted by the primary fan, the Roots fan, the blower, the generator, the screening machine and other equipment in production can reach about 100 dB, sound waves are distributed from low frequency to high frequency, and the surrounding environment is polluted by great noise, so that the normal life of people is seriously influenced. The common treatment means can build a sound barrier outside a workshop or in a factory to block the transmission of sound waves, but the effect is poor, the manufacturing cost is high, and the occupied area is large. The sound source is covered by the sound insulation cover, so that the 'house in house' is formed for treatment, the effect is obvious, the manufacturing cost is low, the overhaul, ventilation and heat dissipation of equipment are affected, the sound insulation cover is not suitable for equipment with small space and high ventilation requirement, and the common sound insulation cover is good in medium-high frequency and poor in low-frequency effect. The method of compromise is to add sound absorbing and insulating plates on the walls of workshops, so that the space is not affected, and the noise reduction effect is excellent. However, the common sound absorption and insulation plate has a common sound absorption and insulation effect, can be reduced by 30 decibels, and is relatively troublesome in manufacturing and installation.
Disclosure of Invention
The integrated sound-absorbing wallboard is convenient to install, excellent in noise reduction effect, modular in production and installation, low in requirements on environment and structure, and wide in applicability, and the engineering progress is accelerated.
An integrated sound-absorbing wallboard consists of a bottom plate, a wedge plate, a blocking plate and sound-absorbing cotton; a plurality of wedge plates are uniformly arranged on the bottom plate; the cavity of the wedge plate is filled with sound absorption cotton, and two side ends of the wedge plate are provided with fixed blocking plates.
A plurality of wedge plates are uniformly arranged on the bottom plate and fixed by rivets or welding; the cavity of the wedge plate is filled with sound absorption cotton, and the end heads at two sides of the wedge plate are provided with fixed blocking plates to form a finished integrated sound absorption wallboard unit.
The whole bottom plate is square, is formed by bending a metal sheet or a non-metal sheet, and the folded edge can increase the mechanical property of the structure, and small holes are formed in the surface according to the use environment. The bottom plate is the bearing structure and the mounting structure of integrated sound absorbing wallboard.
The cross section of the wedge plate is v-shaped, and the sharp angle of the v-shape extends outwards. The wedge plate is formed by bending a metal sheet or a nonmetal sheet, small holes are formed in two sides of the wedge plate, the wedge plate is a main sound absorption unit of the integrated sound absorption wallboard, when sound waves are incident from the tip, due to the gradual transition property of the sound absorption layer, the acoustic impedance of the material can be well matched with that of air, so that the sound waves are transmitted into the sound absorption body and are efficiently absorbed, and the sound absorption characteristic of the sound absorption wedge is related to the wedge length, the filling material and the cavity depth.
The rivet is a standard component and has a fixing function.
The blocking plate is made of the same wedge plate material and corresponds to the cross section shape of the wedge plate, so that the wedge plate and the blocking plate form a closed structure. Plays a role in blocking.
The sound absorption cotton is porous sound absorption material, glass cotton or rock cotton, and has sound absorption effect.
The utility model has the advantages of convenient installation, good noise reduction effect, 50 dB of overall noise reduction, modular production and installation and high engineering construction efficiency.

Detailed Description
The partition wall of an office of a certain power plant is a blower, and noise exceeds standard, so that the office is affected. The design lays the fossil fragments on the wall in its forced draught blower workshop, fills the sound absorption cotton between the fossil fragments, installs this integrated sound absorbing wallboard at the surface of fossil fragments. The expansion bolts are directly used for fixing the integrated sound absorbing wallboard on the office wall.
An integrated sound-absorbing wallboard consists of a bottom plate, a wedge plate, rivets, a plugging plate and sound-absorbing cotton. The specification size is 600 mm x600 mm x200mm. Can be directly arranged on the keel according to the use environment, or on the wall, the modular installation is simple and convenient.
A plurality of wedge plates are uniformly arranged on the bottom plate and fixed by rivets or welding; the cavity of the wedge plate is filled with sound absorption cotton, and the end heads at two sides of the wedge plate are provided with fixed blocking plates to form a finished integrated sound absorption wallboard unit.
The whole 600mm x600mm square that is of bottom plate is bent the preparation by 0.8mm galvanized sheet and forms, and the 15mm hem of rolling up can increase the rigidity of this structure and other mechanical properties, and 6mm apertures are offered to the sound absorbing wallboard surface equipartition that uses in the workshop, and the office wall uses sound absorbing wallboard surface not trompil. The bottom plate is the bearing structure and the mounting structure of integrated sound absorbing wallboard.
The cross section of the wedge plate is v-shaped or triangular, the height of the wedge plate is 200mm, and the wedge plate is formed by bending a galvanized plate with the height of 0.8 mm. Both sides are provided with small holes of 6 mm. The sound absorption wedge is characterized in that when sound waves are incident from the tip, due to the gradual transition property of the sound absorption layer, the acoustic impedance of the material can be well matched with that of air, so that the sound waves are transmitted into the sound absorber and are efficiently absorbed, and the sound absorption property of the sound absorption wedge is related to wedge length, filling material and cavity depth.
One corner of the triangular wedge plate outwards forms a sharp corner, and two plate surfaces forming the sharp corner are uniformly distributed with through holes.
The rivet is a standard piece with the diameter of 4mm and has a fixing effect.
The blocking plate is made of the same wedge plate material and corresponds to the cross section shape of the wedge plate, so that the wedge plate and the blocking plate form a closed structure. Plays a role in blocking.
The sound absorption cotton is glass cotton with 48kg/m sound absorption.
