Description
Technical field
The present invention relates to a kind of angle steel transition node, in particular to a kind of single double angle in iron tower of power transmission line
Transition node.
Background technology
In the design process of iron tower of power transmission line, the especially big load bar on the higher or multiple-loop line road of electric pressure
Tower structure, the internal force of main material may be beyond the bearing capacity of the single angle steel of existing maximum specification.
In this case, it is necessary to will be combined and spliced together for two angle steel, connecting method can be that diagonal cross is spelled
Connect or "T"-shaped splicing, to meet the requirement of structural bearing capacity.Due to the loading characteristic of electric power pylon, the top stress of main material is relatively
Little, bottom stress is larger, and stress larger main material in bottom needs to combine angle steel using Two bors d's oeuveres, and the less main material of top stress can
To adopt single angle steel.
As single angle steel and Two bors d's oeuveres combination angle steel are must assure that while uniaxial force, and meet conventional arrangement habit
Used, i.e.,：The cross section centroidal line of single angle steel is combined the centroidal line of angle steel cross section and aligns collinearly with Two bors d's oeuveres, in addition, as main
The angle steel of material, two limb faces are concordantly coplanar respectively at two adjacent tower body faces, limb facing away from tower body on the outside of, constitute one of tower body
Angle.The single angle steel in top and bottom Two bors d's oeuveres combination angle steel need particular design in the connecting node of intermediate location.
The construction of such node existing, as shown in Figures 1 to 3, is transversely arranged on 1 He of single angle steel with one piece of gusset plate 5
Between Two bors d's oeuveres angle steel 2, the cross section of single angle steel 1 and Two bors d's oeuveres angle steel 2 is vertically connected on by modes such as welding and bolts respectively
Horizontal 5 upper and lower surface of gusset plate, simultaneously need to be aided with a large amount of boots plates and ribbed stiffener 6.In addition, single angle steel 1 and Two bors d's oeuveres angle steel 2
Reinforced by the welding of multiple ribs 6 with gusset plate 5, so as to improve the stress such as tension at node, resistance to compression, bending resistance
Can, the arrangement simultaneously also by ribbed stiffener 6 prevents angle steel root from local buckling occurring.
But, this single angle steel and Two bors d's oeuveres angle steel in the connected mode of transition node lateral arrangement gusset plate, not only structure
Complexity is made, and needs a fairly large number of connecting elements ribbed stiffener so that the workload of processing and welding is too big, it is difficult to be efficiently full
Foot construction needs.
