The invention relates to the environmental protection field of the railway and highway transportation industry, and provides a penetrating sound barrier. It includes the sound absorption panel and the sound absorption back plate, the concave and convex surface of the outer surface of the sound absorption back plate, the reservation panel on the sound absorption panel, and the back plate perforating hole that is reserved with the panel perforating hole, and the sound absorption panel and the sound absorption back form a closed frame through the combination of the panel perforating hole and the back plate perforating hole. A sound absorption body is arranged in the frame cavity, and the sound absorbing body is fixedly connected with the sound absorbing panel and the sound absorbing backplane. The invention provides a perforating hole on the sound absorbing panel and the sound absorbing back plate, and realizes the seamless mechanical connection between the sound absorbing panel and the sound absorbing back plate through the perforating hole, and can be inserted directly without the need of riveting. The purpose of production and installation is fast and stable, which effectively speeds up the construction progress and improves the construction quality, and is simple in structure and convenient in manufacture. In addition, after making templates, large-scale production can be realized. It is of great practical value.
【技术实现步骤摘要】
穿插式声屏障
本专利技术涉及铁路、公路交通行业环保领域,具体涉及一种穿插式声屏障。
技术介绍
金属声屏障加工制作过程中,多采用金属板通孔喷涂内填充吸声材料制作而成,吸音板的表面有很多小孔,声音进入小孔后,透入到吸音材料内部向前传播,被吸音材料吸收后,达到隔声效果。随着隔音效果兼具实用美观的要求不断提高,现有的声屏障迫切需要改变。现有的声屏障的结构存在以下两个缺点:由于现有声屏障的结构主要为面板、背板、侧封板,内部填充隔音材料,这样生产过程较为复杂,耗时耗力,生产成本居高不下。声屏障之间的连接采用铆钉连接,需要在屏体上打孔,使屛体固定。在一般施工时,安装较为不便,影响施工进度。因此,需对现有技术加以改进。
技术实现思路
为克服现有技术所存在的缺陷,现提供了一种穿插式声屏障,用以解决普通声屏障安装不便的问题。本专利技术提供了一种穿插式声屏障,包括吸声面板与吸声背板,所述吸声背板的外表面为间隔的凹凸面,所述吸声面板上预留面板穿插孔,所述吸声背板上预留与面板穿插孔相匹配的背板穿插孔,所述吸声面板与所述吸声背板通过所述面板穿插孔与所述背板穿插孔的配合连接形成封闭的框腔,所述框腔内设有吸声体,所述吸声体与所述吸声面板、吸声背板固定连接。相对于现有技术而言,本专利技术在吸声面板与吸声背板上设置穿插孔并通过穿插孔实现吸声面板与吸声背板的机械无缝连接,可直接插入,不需要铆钉。实现了制作安装快,稳定性强的目的,有效加快了施工进度和提高了施工质量,同时结构简单、制造方便。另外在制作模板后,可以实现规模化生产。具有极高的实用价值。进一步地,所述吸声背板的外表面为相互间隔的凹凸面。保证 ...
