Description

一种互支式桥梁伸缩装置及其转动支架 所属技术领域
本发明涉及一种桥梁伸缩装置， 不仅能满足一般桥梁伸缩需要， 尤其能适应斜桥、 弯 桥和坡桥大位移量、 全方位复合变形。 背景技术
目前使用的桥梁伸缩装置有三大说类：
其一、 模数式桥梁伸缩装置。 对坡桥、 弯桥适应能力有限， 安装维修困难； 而且其横 桥向布置的纵梁在车辆通过时产生振动难以根除， 加速该装置损坏， 缩短使用寿命。 虽然 加减噪板后有所改善， 但纵梁频繁顺桥向受力弯书曲以致疲劳断裂的现象屡见不鲜。
其二， 梳齿板式伸缩装置。 梳齿板的 "整体性" 限制了其对桥梁复合变形的适应力。 虽然近年做了大量改进， 比如： 1、 梳板与梁体采用弹性连接或铰链连接， 2、 引入活动梳 齿， 3、 梳齿支点加高等； 但 ώ于通过对侧梁体支承的方式未变， 没有根除齿端翘起问题， 一些铰接也形同虚设。 对桥梁复合变位的适应能力有限。
其三、 异型钢单缝伸缩装置、 聚合物混凝土伸缩装置、 弹塑体伸缩装置不能适应大位 移量要求。
未见其他能适应桥梁大位移量、 复合变形的伸缩装置。
另， 专利 "防震的连接式桥板伸展接头" （ZL03805728. X ) 中公布的所述 "指状件" 通过第一铰链、 第二铰链与梁体连接， 在适应桥梁复合变形方面有明显进歩， 但增加了桥 梁伸缩装置在顺桥向的安装宽度， 其受力情况也不尽合理。 发明内容
为充分适应斜桥、 弯桥和坡桥的大位移量复合变形， 解决现有桥梁伸缩装置易损坏、 难维修的问题， 本发明中， 半梁 (及中梁②）顺桥向布置， 避免了模数式伸缩装置振动损 坏； 化整为零避免梳齿板式伸缩装置灵活性不足的缺陷； 可充分适应桥梁复合变形， 且维 修方便。
本发明解决其技术问题所采用的技术方案是： 半梁 （及中梁） 顺桥梁轴线方向， 在桥 梁伸缩缝两侧相间或相对安装， 所有半梁及中梁上表面与桥面平齐或基本平齐。 半梁近梁 端@通过转动支架⑤链接在锚固架上。 半梁远梁端④与对侧相邻或相对半梁 (或中梁）， 互以 对方为支承， 并伸缩。 半梁互相支承并伸缩的方案有多种。 方案一、 伸缩缝两侧相间安装 的半梁形状相同， 且半梁横截面为工字形 （两端除外）。 半梁远梁端与对侧相邻半梁（或中 梁)通过滑块轴相互连接， 互相支承。 滑块轴的滑块部分嵌入对侧相邻工字形半梁侧面的 凹槽内， 滑块轴的轴端嵌入半梁远梁端的轴孔内。 相邻半梁或中粱通过其侧面的凹槽支承 滑块轴， 从而支承相邻半梁远梁端或中梁一端。 半梁远梁端的滑块轴在中梁或对侧相邻半 梁侧面凹槽内滑动， 满足桥梁纵向伸缩需要。该半梁方案具有节约钢材、承重量大的特点， 适合公路主车道使用。 方案二、 伸缩缝两侧安装的半梁形状不同， 一侧半梁横截面为工 -字 形 （与转动支架链接端除外）， 对侧半梁截面为矩形， 插入相邻两工字型半梁之间的空腔。 当需加设中梁时， 伸缩缝两侧与转动支架链接的同为矩形截面半梁， 相对插入相邻中梁工 字型截面形成的空腔内。方案三、半梁成对安装， 圆柱状半梁插入芯部为圆形深孔的半梁， 该对半梁互为支承并伸缩。 柱状半梁与芯部带孔的半梁的配合截面形状还可以为矩形、 梯 形、 三角形等。 方案二和方案三结构性能相对较差， 但半梁间间隙较小， 适宜在便道和人 行道安装使用， 以避免较窄的自行车胎和鞋跟陷入。
本发明解决其技术问题所采用的技术方案中， 与上述半梁互支方案一相配合使用的转 动支架为： 转动支架上部中间切槽， 槽宽与半梁宽度相适应； 槽深大于半梁近梁端高度， 给半梁转动留有空间； 槽两侧有同心孔， 用以与半梁远梁端链接。转动支架下部车环形槽， 以便通过定位板连接到锚固架上。 该转动支架下部环形槽中心线与上部槽两侧同心孔的轴 线在同一平面并垂直。 为适应半梁互支方案二、 三以及更多其他半梁互支方案， 转动支架 结构也应在保证两转动轴或孔的轴线在同一平面并相互垂直的前提下， 做相应改变。 半梁 近梁端通过该转动支架链接， 使半梁可绕转动支架竖向轴线转动， 从而满足弯桥伸缩缝扇 形变化和桥梁两端面横向错动。 半梁近梁端通过转动支架链接， 还可使半梁绕转动支架横 向轴线转动， 从而满足桥梁梁端因负荷变化等原因引起的转动 （或称 "翘起"） 及梁端与 桥台上下错动。
为适应桥梁梁端横向错动引起的半梁横桥向间间距变化， 半梁（及中梁）间预留间隙。 半梁互支方案一的半梁远梁端轴孔内两滑块轴间预留间隙， 并设弹性元件， 保证滑块轴滑 块部分嵌入凹槽深度。半梁互支方案一和二， 为避免半梁远梁端相互远离，防止滑块轴（或 矩形截面半梁） 脱出， 保证半梁顺直， 把该装置两端分别相邻两半梁的一侧， 改工字型截 面为 T型槽截面， 与之相配合的滑块轴亦作相应调整。 为延长该桥梁伸缩装置使用寿命， 其转动、 滑动部分采取润滑措施或耐磨防腐材料， 如加装铜垫、 铜套、 四氟垫、 石墨粉、 润滑脂等。
本发明的有益效果是， 半梁远梁端互相支承或借助中梁互相支承， 从根本上解决了齿 端翘起问题， 而且可以伸缩自如。 转动支架的应用不仅满足桥梁复合变位要求， 而且其两 个可转动轴 （孔） 的轴线在同一平面并互相垂直， 更有利于承受来自车辆的载荷。 该转动 支架优于 03805728. X号专利公布的铰链连接， 结构更加合理、 紧凑。 03805728. X号专利的 独立权利要求中明确指出其指状件 "被设置于一滑动支撑件之上" , 而不是 "互相支承"， 使伸缩缝一侧轴线与桥面平行的铰接虚设， 限制了其铰接优势的发挥。 本发明半梁以工字 钢加肋结构为主， 节约钢材， 力学性能优越。 该伸缩装置避免了模数式伸缩装置的振动缺 陷， 并解决了梳齿板缝齿端翘起问题， 凭借其特有的灵活性和适应性， 可充分满足桥梁复 合变位需要， 从而大大延长使用寿命， 而且行车平稳、 生产、 运输、 安装、 维修方便： 附图说明

除专门介绍本发明半梁互支方案的附图外， 均以半梁互支方案一为例示出。 为更多显 示本发明的细节， 在横桥向只画出了一小段， 实际使用中可根据桥梁宽度伸展， 不受限制。 半梁的长度、 宽度、 高度的比例， 也可根据伸缩缝宽度及伸缩量大小相应调整。

图 1为本发明的侧视图。 在本图中， 半梁 1的近梁端通过转动支架 2链接到锚固架 3上， 锚固架 3可通过焊接、 螺栓连接等方式附加锚固肋板 5锚固到钢梁 7上， 也可通过锚筋 6与混 凝土梁或桥台 8固结。 桥梁伸缩缝两侧的半梁互相向对侧伸出， 并通过对侧半梁支承， 具 体支承方式后面详述。 本发明伸缩支承系统不具有防水功能， 其下侧仿齿板缝设止水带 4， 起疏水引流作用。 本图中， 半梁顶面、 转动支架顶面与桥面平齐。 为使图形简洁， 突出原 理， 略去了塞缝条 9、 定位板 14、 滑块轴 1 1等。
图 2以本发明互支方案一为例示出了， 本发明在桥面伸缩缝处安装的情况， 两侧为护 栏。 塞缝条 9的作用为促进桥面平整， 避免石子等杂物落入缝隙。
图 3为图 2的 A- A、 B-B截面示意图。 该图说明了本发明互支方案一中伸缩缝两侧半梁的 远梁端通过滑块轴 1 1在相邻半梁侧面凹槽得到支承的情况。 根据本发明需要适应的桥梁横 向错位幅度大小不同， 同一远梁端轴孔安装的滑块轴 1 1间留有间隙， 两侧相邻半梁间也留 有间隙。 在桥梁梁端 7、 8发生横向错位时， 半梁间间隙及滑块轴轴端间隙减小。 同一半梁 远梁端轴孔内两滑块轴 1 1间安装弹性元件， 向相反方向推动滑块轴 1 1， 以保证滑块轴 1 1始 终保持嵌入相邻半梁侧面凹槽， 防止接触面减小和脱出凹槽。 弹性元件可参考机械设计资 料采取多种灵活方式， 本发明不再详细介绍， 图中也未示出。 ώ于弹性元件的存在， 本发 明半梁有向桥梁两侧 "散开" 的趋势； 所以本发明互支方案一、 二在该装置横桥向端部做 特殊处理， 保持半梁平行、 顺直。 图中半梁 lm的外侧改为 Τ形槽结构； 半梁 I n远梁端滑块 轴孔钻有竖向通孔。 滑块轴 1 1 a滑块部分宽度减小， 以便装入 T形槽； 滑块轴 1 1a轴端钻有 竖向通孔与半梁 I n通过销轴 22连接。 滑块轴 1 1a承受横桥向拉力， 以保持半梁平行、 顺直。
图 4以本发明互支方案一为例示出了本发明加设中梁 12时， 与半梁 1的相互位置关系。 中梁结构示例见图 10。
图 5以本发明互支方案一为例示出了本发明适应桥梁斜缝的安装情况。
图 6以本发明互支方案一为例示出了在桥梁梁端发生横向错位时， 本发明适应这种变 化的变形情况。
图 7以本发明互支方案一为例示出了在桥梁梁端 7、 8发生竖向错位时， 本发明适应这 种变化的变形情况。 为使图形简洁， 略去了塞缝条 9、 定位板 14等。
图 8以本发明互支方案一为例示出了本发明在弯桥上的安装情况和适应桥梁扇形变化 的变形情况。
图 9为本发明互支方案一安装示意图。 滑块轴 1 1装入半梁 1远梁端轴孔 （此处略去了弹 性元件）， 半梁 1与转动支架通过转轴 13链接。 然后， 以上组件向己安装组件平移， 使转动 支架 2底部环形槽与己安装定位板 14半圆形凸台吻合； 同时正在安装的这组半梁的滑块轴 滑块部分嵌入已安装半梁侧面的凹槽， 已安装半梁一侧的滑块轴滑块部分嵌入正安装半梁 侧面的凹槽。 随后再用又一定位板 14半圆形凸台与刚安装的转动支架底部的环形槽吻合， 再用紧固螺丝 10、 塞缝条 9将定位板 14固定到锚固架 3上。 如此在伸缩缝两侧交替安装， 以 满足桥面宽度需要。 从图中可以看到， 半梁的远梁端通过滑块轴嵌入对侧相邻半梁侧面的 凹槽， 该半梁的远梁端得到支承； 同时该半梁侧面的凹槽也为对侧相邻半梁提供支承。 滑 块轴可适应桥梁伸缩需要而在半梁侧面的凹槽内滑动。 半梁远梁端通过对侧半梁互相支承 是本发明的关键， 也是本发明 "互支式桥梁伸缩装置" 名称的由来。
图 10是本发明互支方案一部分组件示意图。 除进一歩放大显示图 9各主要组件外， 还 显示了中梁 12结构图和与滑块轴 1 1起相似作用的滚动轴 15。
图 1 1为本发明互支方案二安装示意图。 半梁 la、 半梁 l b分别交替安装到桥梁伸缩缝两 侧。半梁 lb长方体部分伸入对侧相邻半梁 la侧面凹槽。伸缩缝两侧半梁的远梁端互相支承， 并适应桥梁伸缩需要而伸缩。 安装方式与互支方案一相似不再重复。
图 12为本发明互支方案二加设中梁时的示意图， 旨在说明中梁 12a与半梁 lb的相互关 系， 故略去了其它组件。
图 13、 图 14分别显示了互支方案二中， 中梁 12a、 半梁 la、 lb的结构图。
图 15为互支方案三半梁、 中梁结构示意图。 半梁 lc圆形截面深孔与半梁 Id配合， 远梁 端互相支承并伸缩。 半梁 le矩形截面深孔与半梁 I f配合，半梁 lg梯形截面深孔与半梁 lh配 合,半梁 l i三角形截面深孔与半梁 l j配合，其远梁端分别互相支承并伸缩。 本图以圆形截面 为例示出了该方案加设中梁时的结构示意图， 如图半梁 Id分别从中梁 12b两端插入， 相互 支承并伸缩。 其它截面中梁、 半梁与之相仿。 另外， 图中转动支架 2a显示了又一转动支架 结构形式， 可根据不同半梁近梁端结构需要选用。
图 16为本发明互支方案三在桥面伸缩缝处安装的情况。 半梁 lc、 Id成对在伸缩缝两侧 交替安装， 可缩小半梁间间隙。 另外转动支架 2两外侧边改圆弧为直线， 省去塞缝条 9。
图 17为本发明互支方案三加设中梁时在桥面伸缩缝处安装的情况。
本发明互支方案二和互支方案三在加设中梁时， 为防止中梁 12a (或 12b)滑向一侧半梁 lb (或 ld、 l f、 l h、 l j)而导致另一侧半梁 l b (或 l d、 l f、 l h、 l j)脱出，应在中梁 12a底部安 装相应机构， 其超出本发明范围， 而不再叙述。
图 18为转动支架 2在锚固架 3上安装的又一实施例。 先将 T形槽定位架 16用紧固螺丝 10 固定到锚固架 3上， 然后将转动支架 2底部移入 T形槽内， 两个转动支架 2间用 X形定位块 17 隔开， 以保证转动支架 2间距。 达到桥梁需要的宽度后在 T形槽定位架 16端部用紧固螺丝 10 固定槽端挡块 18以防转动支架滑出。
图 19为又一转动支架 2b和锚固架 20的实施例。 转动支架 2b中部方孔插入半梁近梁端后 用转轴 13链接。 转动支架 2b上下圆柱状凸台与锚固架 20和锚固架上板 21等间距轴孔配合， 最后用螺栓 19和紧固螺丝 10定位。 图 20为本发明中润滑方式的一个实施例。 图中滑块轴滑块部分钻竖向锥形孔， 孔内储 存碳粉、 碳粒、 润滑脂等， 依靠重力作用少量下移进入滑块轴与半梁侧面凹槽的滑动接触 面， 实现润滑。 事实上机械设计方面有多种润滑形式 （如加铜套、 四氟板、 油孔等） 可在 本发明这种类似机械连杆装置上采用， 在此仅举一例。
图 21为本发明引用的 ZL03805728. X专利的附图。 图中关节 312、 关节 332与本发明转动 支架 2作用相似， 都包括两条互相垂直的轴线用以满足指状件 （本发明， 半梁） 平行于桥 面的转动和垂直于横桥向的平面的转动。 不同的是， 其指状件的另一端均依靠滑动支撑件 342支撑， 其指状件 340不能绕插销 334轴线顺时针转动， 插销 334链接无实际意义； 当桥梁 伸缩缝处于较小值时， 若主塔 106升高或主跨 102下降， 指状件 320必然翘起， 影响车辆通 行。 而本发明转动支架所包含的两条互相垂直的轴线在同一平面， 避免了其关节 312、 关 节 332力量传递过程中产生的转矩， 而且结构紧凑。 本发明中转动支架与由半梁、 中梁组 成的伸缩支承系统结合使用， 路面始终平顺， 不会发生翘起。
综述， 本发明一侧半梁的远梁端通过对侧半梁得到支承的同时为对侧半梁远梁端提供 支承， 并实现伸缩； 加设中梁时通过中梁互相支承并实现伸缩。 就结构性能讲互支方案一 最优， 用料省、 承载力大， 可用于机动车道； 互支方案二、 三在桥面形成的间隙小， 可避 免自行车胎、 鞋跟陷入， 但承载力差且表面不够平坦， 可用于便道和人行道。 本发明中转 动支架优于 ZL03805728. X专利的链接方案。 本发明半梁、 中梁组成的互支伸缩支承系统和 以转动支架为主的链接系统结合， 不仅能满足一般桥梁伸缩需要， 尤其能适应斜桥、 弯桥 和坡桥大位移量、 全方位复合变形。 本发明结构合理， 与现有桥梁伸缩装置相比有本质的 区别和明显的进歩， 而且经济实用。 说明：
①半梁： 未见该构件的专用术语， 各类桥梁伸缩装置中起相似作用的 "指状件"、 "活 动梳齿"、 "连杆"等不足以表达该构件既要承重又要互相支承的意义。 参照汽车后轴 "半 轴"命名， 以突出该 "半梁"不具独立性， 一端需依靠对侧相邻半梁或中梁支承并横置承 重之意。
②中梁： 未见该构件的专用术语， 取其位于两侧半梁之间、 桥梁伸缩缝中部， 称为中 梁。
③半梁近梁端： 指半梁靠近桥梁或桥台端部与转动支架连接的一端。
④半梁远梁端： 指半梁远离所在桥梁或桥台的一端。
⑤转动支架： 该支架区别于普通支架的特点为可转动， 称为转动支架。
