具体实施方式
在下文中,仅简单地描述了某些示例性实施例。正如本领域技术人员可认识到的那样,在不脱离本申请的精神或范围的情况下,可通过各种不同方式修改所描述的实施例。因此,附图和描述被认为本质上是示例性的而非限制性的。
下文的公开提供了许多不同的实施方式或例子用来实现本申请的不同结构。为了简化本申请的公开,下文中对特定例子的部件和设置进行描述。当然,它们仅仅为示例,并且目的不在于限制本申请。此外,本申请可以在不同例子中重复参考数字和/或 参考字母,这种重复是为了简化和清楚的目的,其本身不指示所讨论各种实施方式和/或设置之间的关系。此外,本申请提供了的各种特定的工艺和材料的例子,但是本领域普通技术人员可以意识到其他工艺的应用和/或其他材料的使用。
声屏障系统使用的高铁金属声屏障,采用折板扣合结构金属单元板,安装时仅使用薄壁橡胶管隔离振动,而薄壁橡胶管压缩永久性变形大,很快就会失去功效,使面背板直接承受高速列车脉动荷载,易引发结构疲劳损伤。而高铁金属声屏障内部作为吸声系统使用的压力纤维水泥板支撑吸声棉,在使用过程中,水泥板容易出现开裂、岩棉塌落的现象,从而导致高铁金属声屏障失去吸声功能,且高铁金属声屏障重量较重。
高铁金属声屏障是一种减弱交通噪声的装置,通常安装于道路或铁路两侧。由于高铁金属声屏障的使用环境通常存在振动,会引起声屏障振动,形成二次噪声,因而需要在高铁金属声屏障与路基之间安装解耦器。
本申请的目的是,针对现有高铁声屏障存在的弊端,开发一种改进结构的声屏障单元板及声屏障系统,适用于高速铁路、城际铁路、客运专线、轨道交通等领域,能有效削弱列车脉动尖峰荷载、安装方便、提高声屏障耐候性能、结构安全及抗疲劳寿命,吸声材料安装防护牢固杜绝松动、坍塌失效等声屏障解耦器可实现良好的柔性减振效果,且兼具塞缝作用防止漏声,单元板与钢立柱间橡胶条固定牢靠,固定措施不影响橡胶条柔性减振功能,橡胶条加金属盖防护,施工安装过程中不发生撕裂,使用寿命长。
为实现上述目的,本申请采取以下技术方案。

如图1所示,是本申请一种声屏障单元板的组合的侧视剖面结构示意图,其中,100为中部单元板,200为顶部单元板,300为底部单元板,400为声屏障钢立柱;底部单元板300、中部单元板100和顶部单元板200依次插装于声屏障钢立柱400。
如图2所示,是本申请一种声屏障单元板的中部单元板100的侧视剖面结构示意图;其中,1为开孔面板,2为背板,4为横梁,6为竖梁(纵向),7为岩棉,8为岩棉加强筋型材,9为包裹材料、金属防护网,10为框板间胶条,11为单元板间胶条,15为端头,19为横梁承插槽、20为吸声组件、21为排水孔;本申请一种声屏障单元板的中部单元板100的横梁4(上方一个横梁,下方一个横梁)和若干竖梁6通过连接件14铆合连接组成单元板型材框架,开孔面板1和背板2上下、左右边缘均向后折“L”型弯边,面/背板上下“L”型弯边23与横梁4的卡槽扣合,与型材框架连接组成单元板壳体,面/背板左右“L”型弯边24可增强单元板强度;横梁4的卡槽中的面/背板上下“L”型弯边23两侧各设1根框板间胶条10;列车脉动荷载施加到开孔面板1或 背板2上,传递给与之接触的框板间胶条10,框板间胶条10发生变形,其过程吸收和消耗能量,再传递给横梁4,这样主承载结构所承受的列车脉动荷载得到削弱;开孔面板1和背板2采用牌号为3XXX的铝合金板材,框板间胶条10为三元乙丙发泡橡胶,硬度(邵尔A)为30;横梁4设两处横梁承插槽19;单元板间胶条11位于上下单元板之间,装配于下横梁4的横梁承插槽19内;单元板间胶条11为三元乙丙橡胶,硬度(邵尔A)为60;单元板间胶条11可降低振动在各声屏障单元板之间的传递和相互擦碰,降低附加噪声;吸声组件20插装于相邻两个竖梁6(纵向)的卡槽之间;开孔面板1设有冲孔,冲孔为矩形圆角孔,开孔率为29%。单元板两端双侧各设一个端头15,共4个,端头15的下部设排水孔21,可防止单元板内积水。
如图3所示,是本申请一种声屏障单元板的吸声组件侧视剖面结构示意图。岩棉7、岩棉加强筋型材8、包裹材料、金属防护网9组成吸声组件20。岩棉7设沟槽,岩棉加强筋型材8插入岩棉7的沟槽内;岩棉加强筋型材8为“T”型,“T”型短边为弧形,长边为波浪形,采用牌号为6063的铝合金型材;岩棉7表面采用包裹材料、金属防护网9防护,包裹材料为无碱憎水玻璃纤维布,单位面积质量为80g/m2。金属防护网为铝板拉伸网,采用牌号为1060的铝板,厚度为0.5mm,菱形网孔对角线尺寸宜为2mm×4mm,丝梗宽度为0.4mm。
如图4所示,是本申请一种声屏障单元板的顶部单元板200的侧视剖面结构示意图;其中,3为顶部单元板上横梁,5为顶盖;本申请一种声屏障单元板的顶部单元板设顶盖5,顶盖5与顶部单元板上横梁3承插连接,顶盖5采用牌号为6063的铝合金型材。顶部单元板200的其余结构同中部单元板100。
如图5所示,是本申请一种声屏障单元板的底部单元板300的侧视剖面结构示意图;其中,12为底部单元板下横梁,13为解耦胶条;本申请一种声屏障单元板的底部单元板300下部设解耦器,解耦器具有多个与底部单元板下横梁12连接的竖臂133,竖臂133设有开口向下的承插槽134。承插槽134中插置有第一胶条131,第一胶条131至少与相邻的另一个第一胶条131通过第二胶条132连接,形成一组解耦胶条13。
在一个示例中,如图7所示,是本申请一种声屏障单元板的解耦器的局部放大图;解耦器包括与底部单元板下横梁12连接的四个竖臂133,每个竖臂133设有开口向下的承插槽134。每个承插槽134中均插置有顶部有凸起的类“M”型第一胶条131。左侧的两个第一胶条131通过呈细胶条状的第二胶条132连接,形成一组解耦胶条13。右侧的两个第一胶条131通过呈细胶条状的第二胶条132连接,形成另一组解耦胶条13。从而使得解耦器共设两组解耦胶条13。解耦胶条13为三元乙丙橡胶;硬度(邵尔A)为60;底部单元板300其余结构同中部单元板100。
如图6所示,是本申请一种声屏障单元板的中部单元板的俯视剖面结构示意图; 其中15为端头,16为板柱间胶条,17为胶条盖,6为竖梁(横向),21为排水孔,22胶条盖挡头;竖梁(横向)6与横梁4通过连接件14铆合连接,同时相邻两个竖梁(纵向)6之间承插吸声组件20;中部单元板100两端双侧各设一个端头15,共4个,端头15与竖梁(横向)6扣接;板柱间胶条16内置于端头15的卡槽与胶条盖17之间,胶条盖17楔入端头15的卡槽内,胶条盖17外侧设有毛条,横梁4、连接件14、端头15、胶条盖17、竖梁(横向)6、胶条盖挡头22采用牌号为6063的铝合金型材,板柱间胶条16为三元乙丙发泡橡胶,硬度(邵尔A)为30。
如图8所示,是本申请一种声屏障单元板的吸声组件侧视剖面结构示意图。吸声组件20中的吸声材料采用木丝板,木丝板在靠近面板1侧或背板2侧的端面上设置有多个凸起部25。木丝板由于强度和刚度较高,因此可以无需在木丝板外部设置包裹材料和金属防护网。并且木丝板上设置的各凸起部25可以有效的将面板1或背板2上传递的冲击力快速吸收掉,从而防止对木丝板的内部结构造成损害。并且,凸起部25还能够起到加强筋的作用,有效提高整个木丝板结构的强度和使用寿命。凸起部25还能增加木丝板的局部厚度和表面积,提升吸声效果。
在一个示例中,如图9至图11所示,声屏障单元板可以包括横梁4,该横梁4可设置有多个向下伸出的竖臂133,每个竖臂133开设有开口向下的承插槽134。解耦器500包括第一胶条131和第二胶条132。第一胶条131的顶部的凸起111插置于承插槽134中。每个承插槽134用于插置第一胶条131的顶部的凸起111。第二胶条132设置于相邻两个第一胶条131之间,且具有向下凸起的形变部121。其中,形变部121的横截面的形状可以是圆形、椭圆形、矩形、三角形、梯形、拱形等规则几何形状,也可以是不规则几何形状,形变部121的横截面的形状可以根据实际需要进行选择和调整,本申请实施例对形变部121的形状不作限定。
在将声屏障单元板固定于安装面的过程中,可以将第一胶条131的底面和第二胶条132的底面与安装面的表面接触。在声屏障单元板振动的情况下,第一胶条131发生形变,吸收和消耗振动产生的能量,实现良好的柔性减振效果;第二胶条132的形变部121也发生形变,一方面可以实现柔性减振,另一方面可以填充第二胶条132的底面与安装表面之间的缝隙,实现第二胶条132的底面与安装表面之间的密封。由于第二胶条132的形变部121可以填充第二胶条132的底面与安装表面之间的缝隙,因而本申请实施例中由第一胶条131和第二胶条132构成的解耦器500可安装于表面不平坦或具有凹陷的安装表面上,减小安装表面对解耦器500的使用限制。其中,安装面可以是高铁、公路、地铁等交通道路的路基或桥梁基础的安装面,本申请实施例的安装面的类型可以根据实际需要进行选择和调整,只要能够安装解耦器500即可,本申请实施例对此不作限定。
在一种实施方式中,如图9所示,第二胶条132的形变部121为弹性件,可提升解耦器500的吸振能力。其中,弹性件的材料可以是橡胶、硅胶和塑胶等,在一个示例中,弹性件的材料可以是三元乙丙橡胶弹性件。弹性件的材料可以根据实际需要进行选择和调整,本申请实施例对此不作限定。
在一种实施方式中,形变部121的横截面可以呈空心环状。如此,可以减小形变部121的挤压阻力,使得形变部121易于发生形变。其中,空心环状可以是空心圆环状、空心椭圆环状、空心矩形环状、空心三角形环状、空心梯形环状、空心拱形环形,也可以是内圆外方的空心环状、内方外圆的空心环状等,空心环状的形状和尺寸可以根据实际需要进行选择和调整,本申请实施例对此不作限定。
在一种实施方式中,形变部121向下凸起,并超过第一胶条131的底面。如此,在安装表面不平整或具有凹陷时,第二胶条132可有效填充第二胶条132与安装表面之间的间隙,提升解耦器500的密封性能。其中,形变部121向下凸起超过第一胶条131的底面的部分,可以占形变部121整体高度的1/3、1/2等,形变部121向下凸起超过第一胶条131的底面的部分可以根据实际需要进行选择和调整,本申请实施例对此不作限定。
在一种实施方式中,第二胶条132包括两个连接臂122,连接臂122的一端连接形变部121,连接臂122的另一端连接至对应的第一胶条131,形变部121的凸起部分横向于两个连接臂122向下延伸。如此,两个连接臂122可以阻挡形变部121朝远离安装表面的方向运动,使得形变部121在两个连接臂122、相邻两个第一胶条131和安装表面围成的缝隙内进行形变以有效填充该缝隙,提升解耦器500的密封性能。
在一个示例中,第二胶条132的连接臂122的横截面呈细条状。
在一种实施方式中,连接臂122和形变部121一体成型,便于第二胶条132的制作。
在一种实施方式中,第一胶条131的底部设置有至少两个凹槽112以形成形变容纳间隙,当第一胶条131发生形变时,凹槽112可以容纳第一胶条131的变形量,提升减振性能;此外,凹槽112容纳第一胶条131的变形量可以增大第一胶条131的底面与安装面之间的密封面,可进一步提升密封性能。
在一个示例中,第一胶条131的底部设置有两个凹槽112,使得第一胶条131的横截面呈类“M”型。
在一种实施方式中,如图11所示,解耦器500可以包括至少两组解耦胶条组600,解耦胶条组600包括相邻的两个第一胶条131,以及设置于相邻的两个第一胶条131之间的第二胶条132,解耦胶条组600一体成型。如此,不仅可以增强解耦器500的吸振、隔振性能和密封性能,而且可以便于解耦胶条组20的制作。
在一个示例中,可以将两组解耦胶条组600对称设置于横梁4的竖臂133上,使得声屏障的底部可以均匀吸振、隔振和均匀密封。图3示出了两组解耦胶条组600,左边的解耦胶条组600和右边的解耦胶条组600具有相对应的结构。
在一种实施方式中,第一胶条131和第二胶条132的材料包括三元乙丙橡胶;横梁4的材料包括铝合金型材。其中,三元乙丙橡胶的硬度(邵尔A硬度)可以为60,使得第一胶条131和第二胶条132具有较强的耐磨性。
铝合金型材可以采用牌号为6063的铝合金型材,厚度可以大于或等1.5mm,使得横梁4具有较强的刚度和强度。
图12示出根据本申请一实施例的声屏障单元板的结构示意图。如图12所示,声屏障单元板1000包括上述任一种实施方式的解耦器500。
在一种实施方式中,解耦器500通过声屏障单元板1000的横梁4固定于声屏障单元板1000的底部。
上述实施例的声屏障单元板1000的其他构成可以采用于本领域普通技术人员现在和未来知悉的各种技术方案,这里不再详细描述。

在一个示例中,如图9至图11所示,声屏障单元板可以包括横梁4,该横梁4可设置有多个向下伸出的竖臂133,每个竖臂133开设有开口向下的承插槽134。解耦器500包括第一胶条131和第二胶条132。第一胶条131的顶部的凸起111插置于承插槽134中。每个承插槽134用于插置第一胶条131的顶部的凸起111。第二胶条132设置于相邻两个第一胶条131之间,且具有向下凸起的形变部121。其中,形变部121的横截面的形状可以是圆形、椭圆形、矩形、三角形、梯形、拱形等规则几何形状,也可以是不规则几何形状,形变部121的横截面的形状可以根据实际需要进行选择和调整,本申请实施例对形变部121的形状不作限定。
在将声屏障单元板固定于安装面的过程中,可以将第一胶条131的底面和第二胶条132的底面与安装面的表面接触。在声屏障单元板振动的情况下,第一胶条131发生形变,吸收和消耗振动产生的能量,实现良好的柔性减振效果;第二胶条132的形变部121也发生形变,一方面可以实现柔性减振,另一方面可以填充第二胶条132的底面与安装表面之间的缝隙,实现第二胶条132的底面与安装表面之间的密封。由于第二胶条132的形变部121可以填充第二胶条132的底面与安装表面之间的缝隙,因而本申请实施例中由第一胶条131和第二胶条132构成的解耦器500可安装于表面不平坦或具有凹陷的安装表面上,减小安装表面对解耦器500的使用限制。其中,安装面可以是高铁、公路、地铁等交通道路的路基或桥梁基础的安装面,本申请实施例的安装面的类型可以根据实际需要进行选择和调整,只要能够安装解耦器500即可,本申请实施例对此不作限定。

在一种实施方式中,形变部121的横截面可以呈空心环状。如此,可以减小形变部121的挤压阻力,使得形变部121易于发生形变。其中,空心环状可以是空心圆环状、空心椭圆环状、空心矩形环状、空心三角形环状、空心梯形环状、空心拱形环形,也可以是内圆外方的空心环状、内方外圆的空心环状等,空心环状的形状和尺寸可以根据实际需要进行选择和调整,本申请实施例对此不作限定。
在一种实施方式中,形变部121向下凸起,并超过第一胶条131的底面。如此,在安装表面不平整或具有凹陷时,第二胶条132可有效填充第二胶条132与安装表面之间的间隙,提升解耦器500的密封性能。其中,形变部121向下凸起超过第一胶条131的底面的部分,可以占形变部121整体高度的1/3、1/2等,形变部121向下凸起超过第一胶条131的底面的部分可以根据实际需要进行选择和调整,本申请实施例对此不作限定。
在一种实施方式中,第二胶条132包括两个连接臂122,连接臂122的一端连接形变部121,连接臂122的另一端连接至对应的第一胶条131,形变部121的凸起部分横向于两个连接臂122向下延伸。如此,两个连接臂122可以阻挡形变部121朝远离安装表面的方向运动,使得形变部121在两个连接臂122、相邻两个第一胶条131和安装表面围成的缝隙内进行形变以有效填充该缝隙,提升解耦器500的密封性能。
在一个示例中,第二胶条132的连接臂122的横截面呈细条状。
在一种实施方式中,连接臂122和形变部121一体成型,便于第二胶条132的制作。
在一种实施方式中,第一胶条131的底部设置有至少两个凹槽112以形成形变容纳间隙,当第一胶条131发生形变时,凹槽112可以容纳第一胶条131的变形量,提升减振性能;此外,凹槽112容纳第一胶条131的变形量可以增大第一胶条131的底面与安装面之间的密封面,可进一步提升密封性能。
在一个示例中,第一胶条131的底部设置有两个凹槽112,使得第一胶条131的横截面呈类“M”型。
在一种实施方式中,如图11所示,解耦器500可以包括至少两组解耦胶条组600,解耦胶条组600包括相邻的两个第一胶条131,以及设置于相邻的两个第一胶条131之间的第二胶条132,解耦胶条组600一体成型。如此,不仅可以增强解耦器500的吸振、隔振性能和密封性能,而且可以便于解耦胶条组20的制作。
在一个示例中,可以将两组解耦胶条组600对称设置于横梁4的竖臂133上,使得声屏障的底部可以均匀吸振、隔振和均匀密封。图3示出了两组解耦胶条组600,左边的解耦胶条组600和右边的解耦胶条组600具有相对应的结构。
在一种实施方式中,第一胶条131和第二胶条132的材料包括三元乙丙橡胶;横 梁4的材料包括铝合金型材。
其中,三元乙丙橡胶的硬度(邵尔A硬度)可以为60,使得第一胶条131和第二胶条132具有较强的耐磨性。
