Abstract
The utility model in general relates to a novel knick point node and cross node structure for multi-column electric power tower, and more particular to a node structure for electric power tower. A pair of inclined flange plates is arranged in the knick point node area of a main tower pole, so constructed that the flange surfaces are not vertical with respect to the axis of the tower pole, one flange plate being an inclined regular flange plate, the other flange plate being an inclined irregular flange plate, the inclined irregular flange plate being in a bolt connection to the auxiliary tower pole. A cross connecting plate is mounted in the intersection of a plurality of auxiliary tower poles and connect the latters together through bolts. The utility model changes the method of connecting the knick point node area of main tower pole from welding connection to flange plate bolt connection, and also changes the method of connecting the cross node area of auxiliary tower poles from multi-tube welding connection to cross connection plate bolt connection, thus overcomes defects such as welding overlapping, stress concentration, inaccessible welding quality and the like.
Description
Technical field
The utility model relates to the iron tower structure, and particularly a kind of electric power tower becomes sloping node and crossover node new construction.
At present in transmission line of electricity, the four post steel pipe iron towers that are widely adopted, its king-tower bar becomes sloping node and many that are connected the king-tower bar auxilliary tower bar crossover nodes, the general employing disconnects welding method, concentrate on a node welding by many steel pipes, defectives such as this just causes weld seam overlapping, and pad stress is concentrated, and weldquality is difficult up to standard.
The utility model content
Technical problem to be solved in the utility model is, provide a kind of iron tower to become sloping node and be connected the original weld seam connection of replacement with oblique irregular flange plate bolt with oblique regular flange, auxilliary bar crossover node replaces original weld seam to connect with the cross junction plate, problems such as solution is concentrated because of the overlapping stress of weld seam, and the weld seam that causes is insecure.
Technical solution adopted in the utility model is: a kind of electric power tower node structure, and node area is provided with a pair of flange surface and the oblique flange of tower rod axis off plumb on the change slope of the king-tower bar of polystyle iron tower; One of them flange is oblique regular flange, and another flange is oblique irregular flange; Described oblique irregular flange is connected with auxilliary tower bar bolt; The crosspoint of many auxilliary tower bars is provided with the cross junction plate, and the cross junction plate links together many auxilliary tower bars by bolt.
Described cross junction plate form of structure is divided two kinds, and a kind of is that cross iron plate is welded, and another kind is that the flat board of welding different angles on flange is formed.
Owing to adopted above technical scheme, the change slope node of the utility model electric power tower is connected by original dual weld seam with crossover node, changes two oblique flange plate bolts into and connects, and has avoided overlapping because of weld seam, and stress is concentrated the weldquality hidden danger that causes.Same section flange quantity that becomes sloping node use reduces one times, has saved raw material, has reduced cost of production, has improved production efficiency.
Description of drawings
Fig. 1 is the utility model electric power tower node new construction master schematic diagram.
Fig. 2 is an A-A sectional view among Fig. 1.
1 king-tower bar among the figure, 2 oblique regular flange, 3 oblique irregular flange, 4 cross junction plates.
The specific embodiment
Shown in Fig. 1-2, be a kind of specific embodiment of the utility model electric power tower node structure, node area sets firmly a pair of flange surface and the oblique flange of tower rod axis off plumb on the change slope of four-column type iron tower king-tower bar 1; One is oblique regular flange 2, and another is an oblique irregular flange 3, and oblique irregular flange 3 is connected with auxilliary tower bar bolt.Tiltedly flange has played to adjust and has become the slope effect, and it is overlapping effectively to have reduced weld seam.
Set firmly cross junction plate 4 at the intersection of many auxilliary tower bars joint, cross junction plate 4 by bolt the mutual interconnection of many auxilliary tower bars.
Claims (2)
1. electric power tower node structure, it is characterized in that setting firmly a pair of flange surface and the oblique flange of tower rod axis off plumb in the change slope of polystyle iron tower king-tower bar node area, one of them flange is oblique regular flange, and another flange is oblique irregular flange; Described oblique irregular flange is connected with auxilliary tower bar bolt; The crosspoint of many auxilliary tower bars is provided with the cross junction plate, and the cross junction plate links together many auxilliary tower bars by bolt.
2. electric power tower node new construction according to claim 1, the form of structure that it is characterized in that described cross junction plate (4) is that cross steel plate is welded, or the junction plate of welding different angles is formed on flange.
