Joint structure of ramen steel tube tower

摘要

(57) An object of the present invention of the steel pipe in the field joining operation is simple and easy, appearance is good, yet I will provide a joint structure of structurally reliable ramen steel pipe tower. SOLUTION: In the ramen steel tube towers, is spliced ​​to the base plate 3 in the top portion of the lower steel pipe member 2, by welding a cylindrical spliced ​​block 4 on the same base plate, both by fitting the upper steel pipe member 1 in the same block The resin mortar 5 in the gap It is filled with the amount of displacement of the wrap length LP of the cylindrical spliced ​​block and the top steel pipe member in the tension side of the pillars by the horizontal force δ In × 2, I and the on smaller than the diameter of the joint steel pipe.
