Description

一种高性能可维护公路悬臂齿型伸缩缝 技术领域
本发明属于桥梁工程部件技术领域，具体涉及一种高性能可维护公路悬臂齿型伸缩缝。
背景技术
桥梁伸缩装置是为使车辆平稳通过桥面并满足桥梁上部结构变形的需要，在桥梁伸缩处设置的由橡胶和钢材等构件组成的各种装置的总称，它主要由传力支承体系和位移控制体系组成，主要功能一是将车辆垂直和水平荷载通过支承结构传递到梁体，二是适应桥梁纵横位移的变化和梁端翘曲发生的转角变化，一般分为梳齿形伸缩装置或型钢伸缩装置。现有技术的梳齿形桥梁伸缩装置：
1、两侧齿形板由于与其下方的混凝土之间的间隙非常小，使得两侧的齿形板的齿间易卡垃圾，积水不易及时排除，易造成两侧齿形板变形、锈蚀，在安装时，往往和浇筑的混凝土相接触，在后续维修更换时往往需要凿除一些混凝土，操作麻烦，且会导致桥梁结构发生松动，造成安全隐患。
2、锚固件须与原桥预埋件进行焊接，费时费工，且安装平整度难以控制。
因此，急需一种能够解决现有问题的高性能可维护公路悬臂齿型伸缩缝。
发明内容
本发明的目的是提供一种高性能可维护公路悬臂齿型伸缩缝，更换第一悬臂齿形板和第二悬臂齿形板更加方便，钢板在水平方向上的倾斜设置，不易积水，齿间杂物易于及时清理。
本发明提供了如下的技术方案：
一种高性能可维护公路悬臂齿型伸缩缝，包括第一悬臂齿形板和第二悬臂齿形板以及止水带，所述第一悬臂齿形板的一侧的齿和所述第二悬臂齿形板的一侧的齿相错设置，还包括若干锚固结构和两个钢板，所述锚固结构用于支撑固定所述钢板；所述第一悬臂齿形板和所述第二悬臂齿形板的下方分别可拆卸的设有一个所述钢板，所述钢板在水平方向倾斜布置，两个所述钢板的下侧分别可拆卸的连接止水带的两侧，两个所述钢板的上侧均竖向设有第一挡板，两个所述第一挡板分别位于所述第一悬臂齿形板和所述第二悬臂齿形板的远离其上的齿的一侧。所述钢板和所述第一挡板的设置将第一齿形板 和第二齿形板与浇筑的混凝土相隔离，且第一悬臂齿形板和第二悬臂齿形板与钢板可拆卸的连接，使得在后续维修更换第一悬臂齿形板和第二悬臂齿形板时，不需要凿除混凝土，更换更加方便，钢板在水平方向上的倾斜设置，使得钢板和第一悬臂齿形板以及第二悬臂齿形板之间的间隙逐渐增大，齿间的杂物直接落到钢板上并沿着斜面滑落下去，从而使伸缩装置不易积水，齿间杂物易于及时清理。
优选的，所述锚固结构埋入混凝土深度不小于15cm。且现有技术的梳齿形桥梁伸缩装置安装时，连接件需预先与桥梁预埋件焊接连接，施工安装时耗费大量人力物力，且难以控制伸缩装置安装时的平整度。而本设计无须与桥梁预埋件焊接，进而大大缩短施工周期，节省大量的人力物力财力。
优选的，所述锚固结构的表面焊接有若干铆钉。加强锚固性，不易产生松动。
优选的，所有的所述铆钉分为对称的两列，每列所述铆钉沿竖向分布于所述锚固结构上。
优选的，所述锚固结构的表面设有环形槽。加强锚固性，不易产生松动。
优选的，所述锚固结构为螺栓套筒或者地脚螺栓。
优选的，所述锚固结构为螺栓套筒时，所述螺栓套筒的上端穿过所述钢板并通过焊接方式与所述钢板连接，所述第一悬臂齿形板和所述第二悬臂齿形板通过螺栓可拆卸的插入所述螺栓套筒内从而和与之对应的所述钢板可拆卸的连接。螺栓套筒穿过钢板与第一悬臂齿形板或第二悬臂齿形板连接，使得第一悬臂齿形板和第二悬臂齿形板分别和与之对应的钢板之间能够具有一定的间隙，同时相对于第一悬臂齿形板和第二悬臂齿形板分别和与之对应的钢板直接的可拆卸连接(如钢板上侧面设置专门的螺栓套筒)而言，使用的零件少，安装更加方便。
优选的，所述螺栓为高强自锁螺栓，所述螺栓套筒为高强螺栓套筒。
优选的，所述钢板的下侧竖向设有第二挡板，所述第一挡板、所述钢板、所述第二挡板一体合成且呈Z形，所述第二挡板通过螺栓与所述止水带可拆卸的连接。
本发明的有益效果是：
1、本发明通过将第一悬臂齿形板和第二悬臂齿形板与钢板可拆卸的连接，可以方便第一悬臂齿形板和第二悬臂齿形板的维修更换，由于第一挡板的设置将第一悬臂齿形板和第二悬臂齿形板的两侧与混凝土隔离，在更换时，不需要凿除混凝土，更换更加方便，钢板在水平方向上的倾斜设置，使得钢板和第一悬臂齿形板和第二悬臂齿形板之间 的间隙逐渐增大，齿间的杂物直接落到钢板上并沿着斜面滑落下去，从而不易积水，齿间杂物易于及时清理。
2、本发明的锚固结构埋入混凝土深度不小于15cm，使得本发明安装时无须与原桥预埋件焊接连接，因此施工更加方便快捷。

具体实施方式
如图1-4所示，一种高性能可维护公路悬臂齿型伸缩缝，包括第一悬臂齿形板1、第二悬臂齿形板2、止水带3、若干锚固结构和两个钢板5，第一悬臂齿形板1的一侧的齿10和第二悬臂齿形板2的一侧的齿10相错设置，锚固结构为螺栓套筒4也可以为地脚螺栓11，本实施例中使用螺栓套筒4进行说明，这里的螺栓套筒4使用高强螺栓套筒，高强螺栓套筒的上端穿过钢板5且穿过的外壁与钢板5通过焊接连接，钢板5在水平方向倾斜布置，钢板5的上侧和下侧分别竖向设有第一挡板6和第二挡板7，第一挡板6、钢板5、第二挡板7一体合成且呈Z形，两个第二挡板7通过螺栓11与止水带3的两侧可拆卸的连接。两个第一挡板6分列在彼此呈相错设置的第一悬臂齿形板1和第二悬臂齿形板2的两侧，也就是分别位于第一悬臂齿形板1和第二悬臂齿形板2的远离其上的齿10的一侧。第一悬臂齿形板1与第二悬臂齿形板2分别通过高强自锁螺栓8可拆卸的插入螺栓套筒4而与之相对应的钢板5可拆卸的连接。本发明通过将第一悬臂齿形板1和第二悬臂齿形板2与钢板5可拆卸的连接，可以方便第一悬臂齿形板1和第二悬臂齿形板2的维修更换，由于第一挡板6的设置将第一悬臂齿形板1和第二悬臂齿形板2的两侧与混凝土隔离，在更换时，不需要凿除混凝土，更换更加方便；钢板5在水平方 向倾斜设置使得其具有倾斜面，使得第一悬臂齿形板1和第二悬臂齿形板2分别和与之对应的钢板5之间的间隙逐渐增大从而保证第一悬臂齿形板上的齿10和第二悬臂齿形板上的齿10与其对应的钢板5之间具有足够大的间隙，齿间的杂物直接落到钢板5上并沿着斜面滑落下去，从而使得可自行排水的同时，第一悬臂齿形板1与第二悬臂齿形板2的齿与齿之间的杂物不易堵塞，不易阻碍本发明的正常伸缩位移功能，方便清理垃圾。
现有技术的梳齿形桥梁伸缩装置安装时，连接件需预先与桥梁预埋件焊接连接，施工安装时耗费大量人力物力，且难以控制伸缩装置安装时的平整度。为此，本实施例可作如下设计：
具体的，螺栓套筒4埋入混凝土深度不小于15cm，安装时无须与原桥预埋件焊接连接，因此施工更加方便快捷。螺栓套筒4表面通过焊接方式设置有若干铆钉9以及螺栓套筒4表面做环形槽处理，能够加强锚固性，不易产生松动。
在本发明使用的时候，一般该高性能可维护公路悬臂齿型伸缩缝的两端不与混凝土接触，而对于需要与混凝土接触的，可以将钢板5设置成端部凸出其上方对应的第一悬臂齿形板1和第二悬臂齿形板2。
安装方法：
安装时，首先将钢板5放置于槽口内，使用水平尺调整水平度，调整后可临时固定，支护模板，浇筑混凝土。待混凝土强度达到设计值后，将止水带3通过螺栓11连接，后将第一悬臂齿形板1、第二悬臂齿形板2通过高强自锁螺栓8紧固于高强螺栓套筒，安装完成。
以上所述，仅为本发明较佳的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，根据本发明的技术方案及其发明构思加以等同替换或改变，都应涵盖在本发明的保护范围之内。
