A sound insulation board mechanism suitable for municipal construction with high corrosion resistance

Abstract

The invention provides a sound insulation board mechanism suitable for municipal construction with high corrosion resistance, relates to the technical field of sound insulation boards, and solves the problem that the existing sound insulation boards often use a honeycomb slot structure for sound absorption during use. In the process of municipal construction, most of the fence-type sound-absorbing panels used are single-sided closed structures, that is, sound is absorbed on one side and sound is emitted from the other side. The sound-absorbing effect is not good, and it is difficult to achieve the noise generated by construction The problem of the purpose of the partition includes the anti-corrosion end sealing plate; the front and rear end edges between the upper and lower two anti-corrosion end sealing plates are respectively vertically fixed with anti-corrosion outer baffles; the two front and rear anti-corrosion outer baffles U-shaped side sealing plates are respectively vertically slid and clamped at the left and right ends of the body. In the present invention, since the anti-corrosion outer baffle is provided with uniformly spaced four-sided truncated cone-shaped one-way sound-absorbing holes with narrow outer ends and wider inner ends, the sound is reflected, and no matter which side of the sound insulation board comes from the sound Neither can be transmitted from the board.

Description

technical field [0001] The invention relates to the technical field of sound insulation boards, more particularly, to a sound insulation board mechanism with high corrosion resistance suitable for municipal construction. Background technique [0002] Sound insulation walls are mainly used for sound insulation and noise reduction in traffic municipal facilities such as highways, elevated composite roads, urban light rail subways, etc., to control the impact of traffic noise on nearby urban areas, and can also be used for sound insulation and noise reduction of factories and other noise sources. [0003] The existing sound insulation board is a sound insulation device in the patent application CN201910029147.6, the technical solution of which includes a plurality of uprights and a plurality of sound insulation boards arranged between two adjacent uprights. A placement slot, the side end of the sound insulation board is inserted into the placement slot, an insertion slot connec...
