Description

一种膨胀螺栓和槽道组合的固定装置
技术领域
本实用新型涉及一种预埋固定装置，具体涉及一种膨胀螺栓和槽道组合的新型固定装置，用于铁路、地铁等轨道交通的隧道工程中。
背景技术
在铁路、地铁等轨道交通的隧道工程中，接触网的固定装置是一项非常重要的技术。在以往技术中，槽道是与圆盘铆钉，工字钢等焊接在一起，在浇筑混凝土前安放。在实际施工时，如果在原有的混凝土上再浇筑混凝土，需要在已经凝固的混凝土上加装槽道，而后浇筑的混凝土厚度不足预埋槽道。
实用新型内容
针对现有技术的不足，本实用新型的目的旨在提供一种膨胀螺栓和槽道组合的固定装置，解决二次浇筑混凝土时新加装的槽道难以完全预埋的问题。
为实现上述目的，本实用新型采用如下技术方案：
一种膨胀螺栓和槽道组合的固定装置，包括C形槽道和膨胀螺栓；所述C形槽道上设有套管焊接孔，套管一端与C形槽道在套管焊接孔处焊接，将螺母，锥度螺栓，垫圈安装固定。
优选地，所述套管焊接孔上面对应的C形槽道开口处设有扩大的圆形安装孔，方便安装时使用工具。
使用过程中，在原有的混凝土上打孔，将套管和锥度螺栓（膨胀螺栓）插在孔内，使用工具将膨胀螺栓固定后，再浇筑混凝土。膨胀螺栓和C形槽道已经组装在一起，不需要卸下螺母，把槽道放上后再上紧螺母，安装时方便快捷。
本实用新型的有益效果在于：安装方便快捷，能够大大缩短施工工期，具有良好的经济效益。不但可以应用于混凝土二次浇筑过程中，解决槽钢难以预埋的问题，而且可以应用于作业条件不好，需要安装膨胀螺栓的过程中，例高空作业，狭小空间作业。
附图说明
图1是本实用新型实施例1的结构示意图；
图2是本实用新型实施例1中图1的截面图；
图3是本实用新型实施例1中图1的俯视图；
其中：1、C形槽道；11，圆形安装孔，12，套管焊接孔。
21、套管；22、锥度螺栓；23、垫圈；24、螺母。
具体实施方式
以下结合附图对本实用新型所述的一种膨胀螺栓和槽道组合的固定装置作进一步阐述。
实施例1
如图1所示，该一种膨胀螺栓和槽道组合的预埋固定装置，包括C形槽道1和膨胀螺栓，C形槽道1上设有套管焊接孔12，套管焊接孔12的数量至少为2个，膨胀螺栓套管21一端与C形槽道1在套管焊接孔12处焊接，将螺母24，锥度螺栓22，垫圈23固定安装。套管焊接孔12上面对应的C形槽道开口处设有扩大的圆形安装孔11，方便安装时使用工具。
使用过程中，在原有的混凝土上打孔，将套管21和锥度螺栓22（膨胀螺栓）插在孔内，使用工具通过圆形安装孔11将膨胀螺栓螺母24，锥度螺栓22，垫圈23上紧后，再浇筑混凝土。需要安装膨胀螺栓时作业条件不好，例如高空作业，狭小空间作业，也可以使用这种新的组合预埋固定装置。
对本领域的技术人员来说，可根据以上描述的技术方案，做出其他各种相应的改变和扩展，而所有的这些改变及扩展，均应属于本实用新型权利要求的保护范围之内。
