SUPPORT WITH DOUBLE SHELL FROM TWISTED TAPE FOR SUSPENSION OF POWER TRANSMISSION LINE WIRES Russian patent published in 2013 - IPC E04H12/18 

FIELD: construction.

SUBSTANCE: support with a double shell from a twisted tape for suspension of power transmission line wires comprises a free-standing at least one stand in the form of a conical pipe from turns of the tape pulled in process of erection from a roll and connected along the helical line along the supports. In the erected condition the support consists of two conical pipes from turns of tapes, which are connected along the helical line along each pipe. Conical pipes in the erected support are placed one into the other with a gap filled with a hardening filler. The external conical pipe has a non-detachable joint between tape turns, and the inner conical pipe has a connection of the tape turns as tightly overlapping. In the support on top there is a tip connected with the internal and external conical pipes by devices for cross beam fixation (for wire suspension), a lightning conductor and technological accessories for erection (installation) of the support. The support at the bottom has a flange connected with the internal and external conical pipes, which is designed for fixation to the foundation. The support has vessels with foaming and hardening filler, nozzles for filling of the gap between conical pipes by the filler, valves to control the moment of filler filling and traction rods for opening of the valves. Before the erected condition the support is in the folded condition, in which are all the above elements of the support are available, but the tapes are on the flange, being wound into rolls. The support has a property of erection from the folded condition by means of upward pulling by the tip.

EFFECT: higher operational reliability and serviceability of supports, reduced cost and time of construction.
