Cross inserting plate for power transmission line steel tube tower

Abstract

The invention provides a cross inserting plate for a power transmission line steel tube tower, belongs to the field of inserting plate connecting structures in power transmission line steel tube towers, and solves the problem that the cross butt joint gap of a connector is weaker in rigidity, so that overall stress coordination of the connector is improved. The cross inserting plate comprises gusset plates and inserting plates, the gusset plates are crossly arranged to form a gusset plate joint, the inserting plates are crossly arranged to form an inserting plate joint, the gusset plate joint and the inserting plate joint are connected together through connectors and fasteners, and the connectors are crimped plates which are symmetrically distributed about the center of the cross inserting plate. By the aid of the crimped plates, as out-of-plane rigidity is enhanced, lateral bending resistance of crimped combination is enhanced, eccentric compression bearing capacity is improved by 44.51% as compared with that of a strip plate connecting mode, structural stress coordination of the steel tube tower is better, structural stability is enhanced, the connecting mode can be used for connecting joints of main materials, diagonal materials, cross diagonal materials and the like in the steel tube tower, and the cross inserting plate is simple to machine, easy to mount and low in service cost.

Description

technical field [0001] The invention belongs to the field of plate connection structure in steel pipe towers of transmission lines, and in particular relates to a cross-shaped plate for steel pipe towers of transmission lines. Background technique [0002] The cross-type plug-in plate connection type commonly used in transmission line steel towers is 8 strip plates, such as Figure 1-6 shown. figure 1 It includes two gusset plates 3 and 4 connecting the steel pipes arranged in a cross shape, two gusset plates 5 and 6 of the cross-shaped plug joints arranged in a cross shape, and the gusset plates 5 and 6, and the gusset plates 3 and 4 pass through the strips The shaped plates are bolted together. [0003] The connection between the cross-type plate and the steel pipe is the weak part of the joint of the cross-type plate, and the joint is prone to buckling under the action of bending. Bending failure occurred mainly due to the relatively weak stiffness at the butt joint ga...
