Movable sound barrier structure suitable for super-long expansion joint of road bridge
The invention relates to a movable sound barrier structure suitable for a super-long expansion joint of a road bridge, which comprises a plurality of layers of sound barrier unit plates arranged between adjacent steel columns, aluminum profiles are fixedly arranged at the tops and/or bottoms of the sound barrier unit plates, and the adjacent aluminum profiles are clamped together in a relatively sliding manner. The adjacent aluminum profiles are connected together through the safety ropes, so that the two adjacent aluminum profiles can be staggered relatively, and the aluminum profiles located on the innermost side and the outermost side and/or the sound barrier unit plates are connected with different steel stand columns respectively. The movable sound barrier structure can be normally used under the condition that the bridge deck of a bridge road stretches out and draws the original effect of a sound barrier, a traditional single-layer sound barrier unit plate is replaced by a double-layer, three-layer or more-layer sound barrier unit plates, and the number of layers can be specifically set according to different stretching amounts; and the device can be applied to a large-span bridge with a very high requirement range on the expansion and contraction amount.
本发明涉及一种适用于道路桥梁超长伸缩缝处的可活动声屏障结构，其包括设置在相邻钢立柱之间的多层声屏障单元板，所述声屏障单元板顶部和/或底部固设有铝型材，相邻的铝型材之间可相对滑动的卡设在一起，且相邻的铝型材之间通过安全绳连在一起，使两相邻铝型材之间可以发生相对错位，处于最内侧和最外侧的铝型材和/或声屏障单元板分别与不同的钢立柱相连在一起。所述可活动声屏障结构在满足桥道路桥梁桥面伸缩的情况下正常使用以及发挥声屏障的原有效果，将声屏障单元板由传统的单层替换为双层、三层或者更多层，层数可根据不同的伸缩量进行特定设置，可在对伸缩量要求范围很高的大跨度桥梁上应用。
