Embodiment Construction

[0031] figure 1 , figure 2 , image 3 As shown, a multi-spectrum sound barrier unit plate is composed of a supporting structure 1, a sound-absorbing structure, a guard plate, a gusset plate, and a buffer pad.

[0032] The support structure 1 is a frame body; the sound-absorbing structure is placed in the first slot 111 inside the support structure; the guard plate is clamped in the fourth slot 114 on the two longitudinal sides of the support structure, and the buckle plate 3 is pressed against the panel 2 It is inserted into the fourth slot 114 at the two vertical ends of the supporting structure 1, and the buffer pad 7 is installed in the fifth slot 115 to form a complete sound barrier unit board.

[0033] The supporting structure is the main force-bearing and fixed structure, and it is also the outline of the unit plate.

[0034] The support structure is composed of an aluminum plate 11, a middle support frame 13, and corner brackets 12. The aluminum type plate 11 is di...

Abstract

The invention provides a multi-frequency-spectrum sound barrier unit plate. The multi-frequency-spectrum sound barrier unit plate comprises a supporting structure and a sound absorption structure. Thesupporting structure is a frame. And the sound absorption structure is clamped in the middle of the protective plate and is clamped in the groove of the supporting structure. In order to improve thesound absorption coefficient and the effective sound absorption frequency band width, a multi-layer perforated plate series composite structure with different apertures, different perforation rates and different cavity depths is adopted. And the panel and the micro-perforated plate, the micro-perforated plate and the micro-perforated plate, and the micro-perforated plate and the back plate form amulti-cavity structure. The medium-frequency noise and the low-frequency noise can achieve a good effect by consuming energy through resonance in the process of passing through the cavity, and the frequency band amplitude can be expanded for the noise with different frequencies through the cavities with different depths. The invention has the characteristics of high overall strength, universalityof aluminum profiles, few specifications, convenience in installation, flexibility in sound absorption material selection, low cost, wide sound absorption frequency amplitude and the like.

Description

technical field [0001] The invention belongs to the field of environmental protection. It specifically relates to a multi-spectrum sound barrier unit board, which is suitable for sound insulation and noise reduction in traffic and municipal facilities such as high-speed railways, expressways, elevated composite roads, and urban light rail subways. Background technique [0002] With the world's energy crisis and the continuous expansion of environmental pollution, the development and utilization of renewable energy and various green energy to achieve sustainable development has become the only way for human beings in the future. Road noise barriers are widely used for sound insulation and noise reduction in transportation and municipal facilities such as high-speed railways, expressways, elevated composite roads, and urban light rail subways. [0003] The high-speed railway runs fast, and the sound barrier is far from the center of the line. The high-speed railway runs fast,...
