Fastening device for highway guardrail and using method of fastening device
The invention discloses a fastening device for a road guardrail and a using method of the fastening device, and relates to the technical field of fasteners, the fastening device comprises a first guardrail sleeve, a second guardrail sleeve and an adjustable connecting piece, the adjustable connecting piece comprises an inserting piece and an inserting sleeve, one side of the inserting sleeve is rotatably matched with the first guardrail sleeve, one side of the inserting piece is rotatably matched with the second guardrail sleeve, and the inserting sleeve is inserted into the inserting piece. The plug-in and the inner hole of the plug bush are mutually inserted and matched; a first limiting part used for limiting relative rotation of the plug bush is arranged in the plug bush, a second limiting part used for limiting relative rotation of the plug bush is arranged in the plug, and the limit shearing value of the first limiting part is larger than the limit shearing value of the second limiting part; the method is realized based on the device. According to the fastening device and the using method, pure rigid connection between the guardrails can be replaced by non-pure rigid connection with a certain truncation transformation function, so that the pulling force transmitted between the guardrails can be reduced after the guardrails are impacted and buffered, and the toppling rate or deformation rate of the edge guardrails is reduced.
本发明公开了一种公路护栏用紧固装置及其使用方法，涉及紧固件技术领域，该紧固装置包括第一护栏套、第二护栏套和可调连接件，可调连接件包括插件和插套，插套一侧与第一护栏套可转动配合，插件一侧与第二护栏套可转动配合，插件与插套内孔相互插嵌配合；插套内设置有用于限制该插套相对转动的第一限位件，插件内设置有用于限制该插件相对转动的第二限位件，第一限位件的极限剪断值大于第二限位件的极限剪断值；该方法基于该装置实现。该紧固装置及使用方法能够通过将护栏与护栏之间的纯刚性连接替代为具有一定截断变换功能的非纯刚性连接，从而在遭受冲击并提供缓冲后，能够减小护栏之间传递的拉扯力，降低边缘护栏的倾倒率或变形率。
