Length-direction butt-joint structure of prefabricated pulling tip GFRP pipe centrifugal concrete electric pole
The invention provides a length-direction butt-joint structure of a prefabricated pulling tip GFRP pipe centrifugal concrete electric pole, and relates to the technical field of civil engineering. The length-direction butt-joint structure comprises an upper pin pulling rod located on a upper portion, an upper internally-inserted conical steel pipe inserted into the upper pin pulling rod, an upper internally-inserted connecting flange installed at the bottom of the upper pin pulling rod and fixedly connected with the upper internally-inserted conical steel pipe, a lower pin pulling rod located on a lower portion, a lower internally-inserted conical steel pipe inserted into the lower pin pulling rod and a lower internally-inserted connecting flange mounted at the top of the lower pin pulling rod and fixedly connected with the lower internally-inserted conical steel pipe; the pin pulling rod comprises a GFRP pipe and centrifugally-formed concrete, and a conical inner wall is formed in the pin pulling rod; the upper inserted conical steel pipe and the lower inserted conical steel pipe are in close contact fit with the conical inner wall. According to the length-direction butt-joint structure, a taper characteristic of the pull pin rods is fully utilized, tight contact between the upper internally-inserted conical steel pipe and the lower internally-inserted conical steel pipe and the prefabricated pull pin GFRP pipe centrifugal concrete electric pole is achieved, therefore the upper internally-inserted connecting flange and the lower internally-inserted connecting flange are connected and fixed, and butt joint of the upper pull pin rod and the lower pull pin rod in the length direction is achieved.
本发明提供了一种预制拔梢GFRP管离心混凝土电杆长向对接结构，涉及土木工程技术领域，包括位于上部的上拔梢杆、插于上拔梢杆内的上内插锥形钢管、安装于上拔梢杆底部并与上内插锥形钢管固定连接的上内插连接法兰、位于下部的下拔梢杆、插于下拔梢杆内的下内插锥形钢管、以及安装于下拔梢杆顶部并与下内插锥形钢管固定连接的下内插连接法兰；其中拔梢杆包括GFRP管和离心成型的混凝土，拔梢杆内部形成锥形内壁；上下内插锥形钢管与锥形内壁紧密接触配合。本发明充分利用拔梢杆的锥度特点，实现上下内插锥形钢管与预制拔梢GFRP管离心混凝土电杆之间的紧密接触，从而实现上内插连接法兰与下内插连接法兰连接固定实现上下拔梢杆的长向对接。
