Description

一种轻型吸声屏障
技术领域
本发明涉及一种隔音墙， 具体是指一种轻型吸隔声屏障。
背景技术
交通噪音是城市交通向高等级、 高速度、 高架立体等现代化方向发展的 过程中， 机动车数量急剧增加带来的使城市道路交通噪音污染日益严重的噪 音污染。 交通噪声污染问题产生的原因， 主要有两个方面： 一是地面交通设 施已经存在或者已有规划， 在其邻近区域建设学校、 医院、 住宅等噪声敏感 建筑物， 由于规划布局不合理， 未预留必要的防噪声距离， 造成噪声敏感建 筑物投入使用后出现交通噪声污染问题： 二是由于地面交通设施的建设或是 运行造成的环境噪声污染。 除新建地面交通设施可能会产生环境噪声污染外， 一些地面交通设施投入运行后随着车流量的增加， 或运行参数的改变 (如铁路 提速)， 还可能产生新的噪声污染问题。 道路交通噪音具有强度大、 影响范围 广的特点， 已逐渐成为城市环境噪音的主要污染源， 也成为环境噪音控制的 难点。 隔音墙的研制就是为了解决交通噪声对人们生活工作的影响， 从噪音 的源头和传播途径来控制和消除噪音， 隔音墙指的是为减轻行车噪声对附近 居民的影响而设置在公路侧旁的墙式构造物。 但是， 目前的隔音墙存在结构 单一、 重量大、 安装不方便等问题， 研发出重量轻、 安装方便的隔音墙是本 行业的趋势。 发明内容
本发明的目的在于提供一种轻型吸隔声屏障，解决目前的隔音墙重量大、 安装不方便的问题。
本发明的目的通过下述技术方案实现： 一种轻型吸隔声屏障， 包括安装在桥梁护栏或路基上的 H型钢， 在任意 相邻的两个 H型钢之间从下往上依次安装有微穿孔吸声屏、透明屏、 以及三 角锥吸声屏， 在三角锥吸声屏顶部安装有圆弧盖板。 本发明是一种轻型吸隔 声屏障， 由多个单元拼接而成， 在公路路基或者桥梁两侧的护栏上按照设定 的距离预留预埋件，在预埋件上固定 H型钢，每两个 H型钢之间的部分即为 一个单元， 每个单元均包括四个部分： 位于下方的微穿孔吸声屏、 中间的透 明屏、 上部的三角锥吸声屏、 以及三角锥吸声屏顶部的圆弧盖板。 每个单元 可以拆分为四个独立部件， 便于拆卸和安装， 整体重量仅为传统整体式隔音 墙的 60%, 便于运输和安装。 本发明克服了传统声屏障靠矿棉、 发泡树脂等 吸声体在雨水中丧失吸声功能以及尘土堵塞微孔不易清除的弊病， 以丝米级 微穿孔（孔径小于 lmm)金属板为面板构成的吸声体作为核心模块， 可以灵 活组成不同功能多 种型式的系列特宽频声屏障； 通过对孔径、 穿孔率空腔 厚等设计参数的严格计算， 可以较准确预计吸声特性， 其吸声频带宽， 在 100HZ〜5000HZ范围内均能达到良好的吸声效果。
所述的三角锥吸声屏由多个三角锥体单元叠加而成， 每个三角锥体单元 的横截面为直角梯形。 三角锥体是由多个独立三角锥体单元组合而成， 每个 独立三角锥体单元底部采用微穿孔设计， 上部斜面采用百叶孔设计， 当声波 在从下向上传播过程中， 遇到三角锥体单元时， 一部分声波从微穿孔进入， 在吸音材料里面穿行造成声波穿透损失而逐渐衰减， 另一部分声波产生绕射 后遇到三角锥体单元斜面的百叶孔， 声波再次顺利的进入百叶孔， 在吸音材 料里面穿行同样造成音波穿透损失而达到衰减， 因此， 三角锥体单元设计能 更好的起到吸音、 消音及隔音效果。 将外部空间的噪声污染均降到最低， 平 均吸声系数 0.7， 隔声量 30dB， 声屏障基本色调可按客户要求确定， 便于 维护更换。
所述的三角锥体单元安放在 H型钢内，三角锥体单元与 H型钢一侧之间 安装有橡胶密封条， 三角锥体单元与 H型钢另一侧之间安装有定位弹簧。进 一步讲， 相邻两个 H型钢内的内槽相对， 形成存放三角锥体单元的卡槽， 将 三角锥体单元放置在卡槽内， 为了使得三角锥体单元相对 H型钢固定， 在三 角锥体单元与 H型钢的接触的一侧之间垫有橡胶密封条， 在另一侧， 用定位 弹簧卡放在三角锥体单元与 H型钢之间， 定位弹簧处于压缩状态， 其恢复形 变的弹力将定位弹簧与 H型钢夹紧。 H型钢底部采用钢板加固并与预埋螺栓 连接， 使之增强抵御强台风的能力， 其风荷载设计： 按照 46.1m/s的风速设 计。
所述的透明屏为钢化中空玻璃， 在钢化中空玻璃的四周包裹有铝合金边 框，在所述 H型钢上通过螺栓安装有直角钢，所述铝合金边框夹装在 H型钢 与直角钢之间。 进一步讲， 透明屏采用钢化中空玻璃， 在其四周包裹有铝合 金边框， 铝合金边框将两个玻璃的端面夹紧， 以便保护玻璃， 在 H型钢上安 装有直角钢， 直角钢通过螺栓固定， 将透明屏放置在 H型钢和直角钢之间， 铝合金边框与 H型钢或直角钢接触，避免了玻璃直接与 H型钢或直角钢接触， 保护了玻璃。
在所述铝合金边框与 H型钢或直角钢之间设置有橡胶密封条。进一步讲， 为了进一步保护玻璃，在铝合金边框与 H型钢或直角钢之间安装有橡胶密封 条， 橡胶密封条的弹性使得铝合金边框与 H型钢或直角钢接触面最大， 而且 使得玻璃受到的外力均匀传递，有效避免了玻璃的损坏，提高了其使用寿命。 在钢化中空玻璃的侧面与铝合金边框之间设置有硅酮胶。 进一步讲， 在 玻璃侧面与铝合金边框之间填设有一层硅酮胶，不仅起到了粘接牢固的作用， 而且缓冲了玻璃侧面与铝合金边框之间的作用力。 在钢化中空玻璃的端面与铝合金边框之间设置有减震橡胶片。 本发明的 使用环境是道路或桥梁两侧， 难免受到外界的振动影响， 为了减小玻璃受到 的外界震动影响， 在钢化中空玻璃的端面与铝合金边框之间设置有减震橡胶 片， 在玻璃最脆弱的端面垫装减震橡胶片， 可以有效保护玻璃， 提高其抗震 性能。
所述微穿孔吸声屏安放在 H型钢内，微穿孔吸声屏与 H型钢一侧之间安 装有橡胶密封条， 微穿孔吸声屏与 H型钢另一侧之间安装有定位弹簧。 本发明与现有技术相比， 具有如下的优点和有益效果：
1 本发明是一种轻型吸隔声屏障， 在公路路基或者桥梁两侧的护栏上按 照设定的距离预留预埋件，在预埋件上固定 H型钢，每两个 H型钢之间的部 分即为一个单元， 每个单元均包括四个部分： 位于下方的微穿孔吸声屏、 中 间的透明屏、 上部的三角锥吸声屏、 以及三角锥吸声屏顶部的圆弧盖板。 每 个单元可以拆分为四个独立部件， 便于拆卸和安装， 整体重量仅为传统整体 式隔音墙的 60%, 便于运输和安装；
2 本发明是一种轻型吸隔声屏障， 采用三角锥吸声屏独特设计， 符合声 学原理， 加之微穿孔和百叶窗相结合， 采用两个不同面设计， 能够更好的达 到吸音、 消音之效果， 同时整体外观时尚美观， 独具风格， 为城市增添一道 美丽的风景线；
3 本发明是一种轻型吸隔声屏障， 与传统声屏障相比， 具有美观、 透光性 好、 吸隔音性强、 室外耐候性高、 抗老化性好、 自重轻、 使用寿命长、 景观 协调、 美观大方等优点， 适用于多种声学环境噪声治理， 是未来现代城市最 佳的降噪新产品。
