The mutual GFRP pipes for being socketed and there is hollow-core construction, the armored concrete being arranged in GFRP pipes, it is embedded in armored concrete
Grounded round steels and it is arranged on mobile jib bottom and is used for and the steel flange that is connected of basis；The armored concrete include steel reinforcement cage with
And the concrete being integrated is poured with steel reinforcement cage.
The mutual belled position of the GFRP pipes is embedded with the shaped steel of reinforcement, and the shaped steel is poured as one with armored concrete
Body.
The ground wire cross-arm and ground wire upper frame traverse GFRP pipes and poured with the armored concrete and be integrated.
Being made on the steel flange has the bolt hole on several connection bases, or making has the steel pipe connecting with the basis of
The pore connect.
Compared with prior art, the beneficial effects of the invention are as follows：Using GFRP pipes reinforced concrete combined structure member as master
The power transmission rod of bar, the structure type of GFRP pipes about beam core armored concrete cause power transmission rod bearing capacity and non-deformability significantly
Improve, numerous defects of the traditional material transmission line of electricity from vertical rod when bearing larger load are compensate for, particularly in high voltage etc.
Advantage is fairly obvious in level multi-loop line；The combined member remains the preferable insulating properties of composite and high corrosion resistant simultaneously
