一种无缝式减振降噪伸缩装置
本技术属于桥梁
,具体涉及一种无缝式减振降噪伸缩装置。
技术介绍
随着车辆增多,桥梁承受车辆往复荷载越来越频繁。桥梁伸缩缝是整个桥面较脆弱的部位,在频繁荷载作用下,容易引起伸缩装置附近发生疲劳破损。特别对于减振不理想的伸缩装置,更容易使周边混凝土或钢焊缝发生疲劳破损,从而使桥梁过早损坏。对于城市桥梁,伸缩装置处的噪音也是一种重大的污染源,降低伸缩装置处的噪音污染也切合当下国家大政方针。现行行业主流伸缩装置结构的有两个标准,分别为JT/T327-2004《公路桥梁伸缩装置》和JT/T723-2008《单元式多向变位梳形板桥梁伸缩装置》,但这两个标准所规定的活动型支座结构各有利弊。标准JT/T327-2004《公路桥梁伸缩装置》规定的模数式伸缩装置采用各种型钢组合而成。优点在于锚固可靠,使用寿命长。缺点在于减振降噪效果不好。标准JT/T723-2008《单元式多向变位梳形板桥梁伸缩装置》规定的梳形板式伸缩装置采用梳形板捏合。优点在于行车平顺,减振降噪效果好。缺点在于梳形缝间容易积压尘土,一段时间后,灰尘形成坚固物质,阻止伸缩装置的位移 ...
