Description

Buckle plate, composite function plate and noise reduction, sound absorption and insulation and magnetic conduction elimination method

Technical Field

The invention relates to the technical field of noise reduction, sound absorption, sound insulation and magnetic conduction elimination based on an assembled buckle plate and a barrier, in particular to a buckle plate, a composite function plate and a noise reduction, sound absorption, sound insulation and magnetic conduction elimination method.

Background

In recent years, most of electromagnetic pollution generated by noise environment simultaneously does not draw enough attention of people, the existing sound barrier construction only focuses on structural design in practice, the acoustic design is lack of sufficient understanding, or the acoustic design is only carried out by experience or feeling, some sound barriers even reduce investment or simply consider from the aspect of landscape, the height and the length of the sound barrier are artificially reduced, the noise reduction effect of the sound barrier is greatly reduced, the engineering cost is increased, material resources are wasted, and the integration with other functions and material technologies has huge defects. In addition, the application of intelligent terminal equipment and intelligent facilities is not enjoyed in recent years, and physical coping methods for electromagnetic hazards and information leakage caused by such equipment and facilities are relatively lacking.

The existing sound barrier is only suitable for road traffic with low-medium noise frequency and does not have the electromagnetic function of a noise guide and elimination screen; and the landscape effect is greater than the noise reduction effect, and the aluminum metal plate with the thickness of 8mm is adopted, so the manufacturing cost is higher, and the installation is complicated and the engineering cost is increased because the modularized design, the manufacture and the installation of other compatible functions such as transparency, landscape viewing, illumination and the like are not realized.

With the development of the application times of intelligent mobile terminal equipment and intelligent facilities, the physiological harm which can be generated by the human body and the interference to other electronic elements are increasingly obvious due to the electromagnetic pollution in a closed or semi-closed traffic space and a building space, and in addition, the electromagnetic signal leakage and the lack of confidentiality cause great loss to relevant units no matter whether military secrets or commercial secrets. Under the condition of coexistence of urban high, medium and low frequency noise pollution and electromagnetic pollution, the single sound barrier material and measure are difficult to deal with the increasingly severe electromagnetic pollution.

Based on the above factors, the inventor conducts an intensive study, and the metal plate is the best choice material with the noise reduction and shielding magnetic composite effect, and the fiber metal plate is the best choice plate. When the metal plate forms a six-sided shell with a certain cavity depth, the functions of demagnetization and noise elimination of the metal shell can be realized. Electromagnetic shielding and high frequency noise shielding can be achieved when the metal housing is combined with the associated materials. The inner side of the shell is coated with electromagnetic wave absorbing coating and embedded with a composite sound absorbing cotton plate, and a glass cotton plate is not used. The metal shell can absorb, separate and electromagnetically shield high, medium and low frequency full-band noise. And the zero maintenance, difficult corrosion and service life increase of the electromagnetic coating are realized.

In addition, compared with an active noise reduction method based on an electronic system, the active noise reduction method is pure physical noise reduction, so that noise reduction and incapability caused by electronic system faults are avoided, and later maintenance cost and high-frequency electromagnetic interference are reduced.
