Power transmission tower angle steel connection joint

Abstract

The invention relates to a power transmission tower angle steel connection joint. The power transmission tower angle steel connection joint comprises two principal materials, diagonal materials, diaphragm materials and auxiliary materials, wherein the principal materials are arranged in the vertical direction and serve as tower pillars, the diagonal materials are connected between the two adjacent principal materials, the included angle of the diagonal materials and the horizontal direction is smaller than 90 degrees, the diaphragm materials are horizontally arranged between the principal materials, and the auxiliary materials are connected with the principal materials, the diaphragm materials and/or the diagonal materials. The power transmission tower angle steel connection joint is characterized in that the principal materials which serve as the tower pillars comprise two or more principal material sections which are connected with one another in a head-to-tail mode; the tower pillars are composed of the principal material sections, the principal material sections comprise cross-shaped connecting plates which are perpendicular to each other and angle steel arranged on the crosswise intersected included angle portions. According to the power transmission tower angle steel connection joint, under the situation that the thicknesses of filler plates are different, connecting can be conducted among the principal material components according to the filler plate thicknesses obtained through actual calculation, the tower weight is reduced, it is guaranteed that the connection of the components is safe and reliable, and the economical efficiency of the tower is achieved.

Description

technical field [0001] The invention relates to a supporting device for a power transmission line, in particular to a connection node of an angle steel connection of a power transmission tower. Background technique [0002] With the rapid development of the economy, the demand for power is increasing day by day, the dependence on power energy is increasing day by day, and the requirements for the safety and reliability of the power grid are becoming increasingly strict. The transmission tower is an important support of the power grid. It is installed in the natural environment and is attacked by severe weather disasters, which will damage the structure of the tower and cause collapse and damage. [0003] Strengthening the main material of the transmission line tower can improve the ability of the transmission line to resist disaster weather and improve the safe operation level of the transmission line, which has very important economic and social benefits. [0004] Single-a...

Problems solved by technology

The use of filler plates of the same thickness is beneficial to the connection between the main materials of the combined angle steel, but to a certain extent, it causes waste of steel and increases the cost of the tower
