Description

技术领域
本发明涉及一种桥梁梁体之间的伸缩缝装置， 尤其涉及一种无砼型桥梁伸缩缝装 置。 背景技术
为了满足桥梁梁体变形的需要， 一般在桥梁的两梁端之间、 梁端与桥台之间或者桥 梁的铰接位置上都安装有桥梁伸缩缝装置。 在现有的桥梁伸缩缝装置中， 如图 11 和图 12所示， 梁体 la进行制作时， 在梁体的端部预留供伸缩装置 2a安装的槽口， 在预留槽 内预埋钢筋 3a， 伸缩装置 2a进行现场安装时， 首先在桥面铺装沥青层 5a时将伸缩装置 安装槽口全部覆盖， 然后根据伸缩装置安装宽度要求将安装槽口切割打挖清理干净， 将 伸缩装置 2a与预埋的钢筋 3a进行固定， 最后在预留槽内浇注过渡段混凝土 4a并对混 凝土进行养护， 待混凝土养护完毕后才可开放通车。
上述现有的桥梁伸缩缝装置存在如下缺陷：
其一，需要在现场浇注混凝土， ώ于混凝土的施工和养护均要受到气候和工期等因 素的影响， 因此， 过渡段浇注混凝土的结构已成为整个桥梁伸缩缝装置构造和工程中的 最突出问题。
其二， 施工工序较多， 人力成本及造价较高。
其三， 由于沥青与混凝土的刚性度不一， 沥青呈柔性， 而混凝土呈刚性， 因而伸缩 缝装置长久使用后， 易产生沥青凹陷现象，而沥青一旦凹陷，则容易使混凝土产生破碎， 并进而损坏伸缩缝装置， 从而降低车辆经过桥梁伸缩缝时的平顺性和舒适性， 甚至影响 到行车的安全性。两恻过渡段混凝土破损是现有桥梁忡縮装置损坏的最主要病因， 尤其 像结构合理性能可靠的单元式多向变位梳形板桥梁伸缩装置， 90%以上的损坏都 其造 成。
其四， 一旦伸缩缝装置遭到损坏， 修复时需要打碎清理整个混凝土层， 并重新进行 伸缩装置的安装、 混凝土的施工和养护， 从而浪费了更多的人力、 物力和财力。
其五， 其伸缩装置的安装深度较高， 无法在桥面铺装层的厚度内进行安装作业， 需 在梁体端部预留相应的安装槽口， 加大了梁体的施工难度及制作成本。
综上所述， 有待对现有的桥梁伸缩缝装置进行改进。 发明内容
- 1 - 确认本 本发明所要解决的技术问题是针对上述现有技术现状， 而提供一种安装时无需预留 安装槽区、 两侧没有混凝土过渡段、 破损率低、 维护方便的无砼型桥梁伸缩缝装置。
本发明解决上述技术问题所采用的技术方案为： 该无砼型桥梁伸缩缝装置， 包括分 别设置在桥梁伸缩缝两侧的第一梁体、 第二梁体以及伸缩构件， 其特征在于： 在所述第 一梁体和第二梁体邻近伸缩缝的表面上分别预设有钢垫板， 所述的伸缩构件安装在所述 的钢垫板上。
优选地， 在所述钢垫板及对应梁体位于所述伸缩构件外侧的表面上铺设有桥面铺装 层， 且该桥面铺装层的上表面与伸缩构件的上表面相齐平。 在所述钢垫板及对应伸缩构 件安装固定后， 铺设桥面铺装层时直接延伸至其两侧， 桥面铺装层可以多种铺装材料， 比如可以采用沥青、 混凝土和环氧树脂等。
进一歩优选， 所述的钢垫板埋设在对应梁体上， 且钢垫板的上表面齐平于该对应梁 体的上表面。 当然， 钢垫板预埋完毕后， 钢垫板的上表面也可以高于或者低于对应梁体 的上表面。
为了对钢垫板进行加固， 在所述钢垫板的底部固定有埋设在对应梁体内的连接钢 筋。 连接钢筋与钢垫板焊接固定后在梁体制作时预埋设在梁体中。
作为伸缩构件的一种优选方案， 所述的伸缩构件包括相互交叉间隔设置的梳齿板， 在所述梳齿板的外侧分别设有一防撞挡板， 所述的防撞挡板固定在对应的钢垫板上， 所 述的桥面铺装层铺设在防撞挡板的外侧， 且所述梳齿板及防撞挡板的上表面与所述桥面 铺装层的上表面相齐平。 防撞挡板为钢板， 可以焊接在钢垫板， 也可以与钢垫板为一体 件， 并且在需要加厚桥面铺装层的场合， 可以根据加厚的高度在防撞挡板的顶部进行加 高焊接， 从而调整伸缩缝装置的安装高度。
所述的梳齿板包括固定梳板和跨设在伸缩缝上的活动梳板， 固定梳板的第一端与活 动梳板的第一端相互交叉间隔设置。 固定梳板的第二端和活动梳板的第二端分别通过所 述的锚固螺栓固定在对应侧的钢垫板上， 在所述活动梳板的第二端通过具有随梁体进行 转角变位的转动结构固定在钢垫板上。 活动梳板的第二端设计成可转动结构后， 使得在 梁体产生挠度变形、 梁端上翘或下沉时， 活动梳板与梁体之间会发生转动， 从而使活动 梳板保持平整的姿态， 避免整个伸缩缝装置因此而引起损坏， 保证车辆平顺安全通过。
为了对伸缩构件作进一歩加固， 在所述防撞挡板的内侧且位于钢垫板的上方浇注有 填充层， 所述的梳齿板设于该填充层的上方。 填充层可以是沥青或其它类型的混凝土填 充层。 在梳齿板的底部与填充层之间自上而下可以依次设置不锈钢板和缓冲胶板。
为了对防撞挡板作进一歩加固， 所述防撞挡板的外侧面与钢垫板之间设有加强肋。 加强肋优选采用钢板， 可以是与防撞挡板和钢垫板均焊接固定， 也可以是与防撞挡板为 一体件并焊接在钢垫板上， 也可以是与防撞挡板和钢垫板为一体件预埋在梁体内。
作为止水构件的一种安装结构， 在所述伸缩缝的两侧分别固定有一梁端隔板， 在梁 端隔板上安装有止水构件。梁端隔板与钢垫板焊接固定或者固定在填充层靠近伸缩缝的 端面上， 并且， 在梁端隔板上表面跨梁体表面保留梳齿板及止水构件的安装高度。
作为伸缩构件的另一优选方案， 所述钢垫板内侧端的端面齐平于桥梁伸缩缝， 所述 的伸缩构件包括固定在钢垫板内侧端的伸缩体，所述伸缩体的上表面齐平于所述桥面铺 装层的上表面， 在伸缩体上安装有止水构件。 伸缩体可以采用内侧设有安装槽的金属挡 板， 止水构件的两侧分别嵌入并固定在安装槽内。 伸缩体也可以采用内侧开有止水构件 安装槽的各种异型型材， 止水构件的两侧镶嵌在异型型材的安装槽内。
为了对伸缩体作进一歩加固， 所述伸缩体的外侧面与钢垫板之间设有加强肋。 加强 肋优选采用钢板， 可以是与伸缩体外侧和钢垫板均焊接固定， 也可以是与伸缩体为一体 件并焊接在钢垫板上。
上述伸缩构件在安装时， 均在桥面进行沥青铺装前将伸缩体与钢垫板安装固定， 桥 面铺装层铺装时直接铺设至伸缩构件的两侧接平， 包括必要时可先填平后安装的梳齿板 位置的空间。
与现有技术相比，本发明通过在伸缩缝两侧的梁体表面上分别预设钢垫板， 并在钢 垫板上安装伸缩构件， 从而使桥面铺装层可以直接延伸至伸缩构件的两侧， 伸缩构件与 沥青铺装层之间没有混凝土过渡段， 因此具有如下优点：
1、 取消了梁体端部的预留槽过渡段混凝土构造， 结构简华、 施工简化， 利于工厂 化统一化制梁；
2、 ώ于取消了过渡段混凝土结构， 因而不仅简化了施工工序， 克服了气候、 工期、 材料等因素对混凝土施工和养护的制约， 并且有效避免了因混凝土破碎引起的各种伸缩 缝装置损坏现象， 大大提高结构安全， 降低营运成本；
3、 伸缩缝装置遭损坏进行维修时， 只需要更换和重新安装伸缩构件和止水构件， 并只需局部修铺沥， 维修方便工期短且即修即通， 特别适合城市工程；
4、 伸缩缝装置的高度可以根据桥面铺装层的厚度进行调整， 使用非常灵活。 附图说明
