(57) Abstract Objective Being provided in the bottom of the metal tubing iron manufacture tower main pillar, tube continuingThe rainwater and the internal dew condensation water which from the hand part invaded inside the main pillar are dischargedThe ru collar brace hole, with the area swage block and the like which invaded this borehole stuffingRoundly, the hollow metal tubing iron manufacture tower for overhead power transmission in order to cancel fearThe collar brace coming hole insect proof metallic parts in the main pillar material are offered. Constitution Having the external form like the L shape of character duct as a wholeThe time, to designate the transverse part as insertion portion 1 to the collar brace hole, the longitude sectionIn the collar brace section which designates amount as collar brace section 2, does angular tubed, husband Various closingIn each of the base and the top face and the edge strip which are done the multiple water flow holes 3A - 3C it made the configuration which provides. It forms the water flow hole in rectangular conditionThe ru it is good. And, as for the insertion portion, the time tune doing, the elastic plate to the angular gutter-shapedAs it forms, provides the break in the arris part free edge side outsideAs you make open to direction, person in charge stopper claw a should have been provided.
