High-strength wind-resisting electric power tower

Abstract

The invention discloses a high-strength wind-resisting electric power tower which comprises five circular truncated cone bases, and second supporting columns are fixed in the five circular truncated cone bases. A first supporting seat is fixed at the upper ends of the four second supporting columns, six first bolts are fixed in the middle of the upper end of the first supporting seat, first supporting columns are arranged at the upper end of the first supporting seat, and the first supporting columns are connected with the first supporting seat through the first bolts. A first flange plate isfixed at the upper end of each first supporting column, a second flange plate is arranged at the upper end of each first flange plate, and the second flange plates are connected with the first flangeplates through second bolts. The bases of the tower are changed and one more base is added to support the tower body of the second layer in an auxiliary mode, and the first layer is changed into roundcolumns capable of bearing higher pressure, so that the problem that a tower collapses due to the fact that upward-pulling of the tower is caused by the effect of wind and inclined strut instabilityis caused by small loads of the first and second sections of the tower body is solved, and the high-strength wind-resisting electric power tower is suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of wind-resistant electric power towers, in particular to a high-strength wind-resistant electric power tower. Background technique [0002] Transmission line towers are generally divided into five types according to their shapes: wine glass type, cat head type, upper type, dry type and barrel type. Terminal towers and spanning towers, etc., their structural characteristics are that all kinds of tower types are space truss structures, and the rods are mainly composed of single equilateral angle steel or combined angle steel. Force connection, the whole tower is composed of angle steel, connecting steel plate and bolts, individual parts such as the tower foot are welded into an assembly by several steel plates, so hot-dip galvanized anti-corrosion, transportation and construction erection are extremely convenient. For towers with weak tower foundations, When the anti-overturning ability does not meet the ext...

Problems solved by technology

[0002] Transmission line towers are generally divided into five types according to their shapes: wine glass type, cat head type, upper type, dry type and barrel type. Terminal towers and spanning towers, etc., their structural characteristics are that all kinds of tower types are space truss structures, and the rods are mainly composed of single equilateral angle steel or combined angle steel. Force connection, the whole tower is composed of angle steel, connecting steel plate and bolts, individual parts such as the tower foot are welded into an assembly by several steel plates, so hot-dip galvanized anti-corrosion, transportation and construction erection are extremely convenient. For towers with weak tower foundations, When the anti-overturning ability does not meet the extreme wind force, there will be different degrees of uplifting, which is one of the important reasons for the toppling of the tower. It can be seen from the common characteristics of the transmission tower collapse caused by the squall line wind in East China that the damage is mainly concentrated At the position of the first and second tower sections on the upper part of the tower legs, the local mode shape and out-of-plane displacement appear on the first and second tower section diagonal braces at the same time, and the wind load itself is a dynamic load. Therefore, in The diagonal bracing in this part is unstable, which leads to the collapse of the tower. Therefore, we have designed a high-strength wind-resistant power tower to solve the above problems
