Abstract

The invention discloses a plug-in board connection assembly and a steel pipe tower of a power transmission line. The plug-in board connection assembly includes two gusset plates arranged in a cross shape as a gusset plate joint and two plug plates arranged in a cross shape as a plug-in board joint, and the gusset plate The joint and the plug-in board joint are butt-connected together by using fasteners through the connecting member, and the connecting member includes two, three or four angled pieces, wherein the two angled pieces are symmetrically arranged with respect to the center of the plugged-in board connection assembly. Through the plug-in plate connection assembly of the present invention, the advantages of simple connection, good structural force coordination, strong stability and sufficient force of angle steel or bent plate are realized.

Description

technical field [0001] The invention relates to a plug-in board connection structure in a steel pipe tower of a power transmission line, in particular to a plug-in board connection assembly. Background technique [0002] The connecting components of the cross plate commonly used to connect steel pipe towers of transmission lines are eight strip plates. figure 1 It is a schematic structural diagram of a cross-shaped board connected by eight strip boards in the prior art. exist figure 1 Among them, it includes two gusset plates 3 and 4 arranged in a cross shape as gusset plate joints and two insert plates 5 and 6 arranged in a cross shape as insert plate joints, and the gusset plate joints and insert plate joints are adopted through the strip plate 9 bolted together. The connecting component connecting the cross-shaped plate and the steel pipe 2 is the weak part of the joint load of the cross-shaped plate, and the connecting component is prone to buckling under the action o...
