Abstract

The invention discloses a reinforcement method for improving local stress concentration of a power transmission double steel pipe pole connection node. The connection node is positioned at the joint of any one main pole of double steel pipe poles with a connection rod and a cross arm. Connection pipes are arranged on inner and outer sides of each main pole, the outer connection pipe of each main pole is connected with the cross arm through a connection pipe flange, and the inner connection pipe of each main pole is connected with one end of the connection rod through a connection pipe flange.The other end of the connection rod is connected with the other main pole through the corresponding connection pipe flange and the corresponding connection pipe. One side of each connection pipe flange is connected with the corresponding connection pipe through connection pipe flange ribs and connected with the corresponding main pole through connection pipe flange square ribs. The other side of each connection pipe flange is connected with the connection rod or the cross arm through connection pipe flange ribs, two sides of each connection pipe flange are fastened through bolts, and each connection pipe is connected with the corresponding main pole through a plurality of special-shaped stiffening plates. The problem of high local stress concentration of the connection node of the double steel pipe pole structure under adverse design conditions is solved, and simplicity and practicality in structural reinforcement, elegance in appearance and convenience in construction are realized.

Description

【Technical field】 [0001] The invention relates to a reinforcement design, in particular to a reinforcement method for a connection node of a double steel pipe rod structure of a power transmission line. 【Background technique】 [0002] With the rapid development of my country's social economy, the country is accelerating the pace of urbanization, and the line corridors in urban planning areas and suburban areas are becoming more and more tense. Most of the lines pass through urban green belts, sidewalks and other crowded areas, and the roots of conventional angle steel towers are large. In urban green belts, sidewalks follow lines. As the voltage level is getting higher and higher, and the load is getting bigger and bigger, the general single-rod steel pipe pole can no longer meet the needs of engineering design. Double-pole steel pipe poles have the advantages of small footprint, convenient construction, etc., and can meet higher voltage levels, so they are gradually widely ...
