Abstract
The utility model discloses a break-resistant wave-shaped flange, which comprises a flange plate, wherein a flange neck tube is arranged on the flange plate, the shape of the end surface of the flange neck tube used for externally welded joint is continuous convexo-concave shaped. The break-resistant wave-shaped flange avoids the problems of welding defects of the conventional hubbed flange for flat position welding and the hubbed flange for butt welding and welding heat affected zone ring-shaped concentration, and can prevent a steel pipe from even opening break effectively; the safety reliability of a steel pipe node and a pylon component is improved effectively; the wave-shaped flange is welded at the end part of the steel pipe, each component is connected through bolts, and the processing and installation are convenient; and the flange can be applied to such fields of transmission line steel tubular towers, communication steel tubular towers and television steel tubular towers.
Description
Technical field
The utility model belongs to steel pipe shaft tower parts, has to relate to a kind of steel pipe shaft tower pipe fitting flange connecting that is used for.
Background technique
Steel pipe shaft tower circuit uses widely in the electric power system field of power transmission; In the structure of existing steel pipe shaft tower, the node connectivity problem of steel pipe shaft tower is the most key emphasis of structural design and difficult point.It is that the steel pipe connection is generally the flange connection that existing node connects, and wherein forging the flange standard type is downhand welding hubbed flange and butt welding hubbed flange, and this type of flange neck is flat neck.Yet the flange of these two kinds of patterns connects the subject matter that exists following 3 points:
(1) downhand welding band neck and butt welding hubbed flange disc-annular shape weld seam are positioned on the same section of steel tube member bar, and the weld defect that exists in the weld seam concentrates on same section, and this makes the reduction in strength of this section, and steel strength is not fully utilized.
(2) because the existence of welding residual stress, make that certain zone of weld seam can strength failure at first take place and then cause the neat mouthful brittle fracture of whole section generation thereby cause this section because the stack of residual-stress value and design stress value make the stress total value early reach material yield intensity between the person in charge and the flange plate.
(3) welding heat affected zone of circular weld concentrate on same section circular weld around, the fragility of these same section heat affected zone steel increases greatly, occurs the brittle failure phenomenon easily.
Because the defective of said structure in the actual using process of steel pipe shaft tower, the accident of the pipe fitting joint fracture in the steel pipe shaft tower occurred, causes tremendous loss.
Summary of the invention
The purpose of this utility model is to provide a kind of break-resistant wave-shaped flange that can avoid the pipe fitting joint fracture in the steel pipe shaft tower, to address the above problem.
The technical solution of the utility model is: break-resistant wave-shaped flange, and it comprises flange plate, and flange plate is provided with the flange neck tube, and it is continuous concaveconvex shape that the neck flange pipe is used for the outer end surface shape that connects welding.
One or more the combination that is waveform, sinusoidal waveform, arc, profile of tooth or zigzag fashion that described neck flange pipe is used for the outer end surface shape that connects welding.
When break-resistant wave-shaped flange node of the present utility model connected, steel pipe inserted in this flange, adopted between the end face of fillet weld welding or steel pipe and flange neck tube employing to dock welding between steel pipe and flange plate hole, and the realization steel pipe is connected with flange.The layout advantage of wave mode weld seam has such several respects: at first, the wave mode weld seam has increased heat diffusion area, is example with the weld seam of unit length, and the heat diffusion area of circumferential weld is rectangular, and the heat diffusion area of wave mode weld seam is disperse fan-shaped; Secondly, the wave mode weld seam is easy to the weld defects that staggers, and avoids the annular of weld defects to concentrate; The 3rd, the wave mode weld seam has increased fusion length, has strengthened the join strength of steel pipe and flange; The utility model has been avoided the weld defects of hubbed flange of the hubbed flange of existing downhand welding and butt welding and the problem that welding heat affected territory annular is concentrated, can effectively prevent the generation of neat mouthful of fracture of steel pipe, effectively raise the safety reliability of steel pipe node and iron tower member; Wave-shaped flange is welded on steel tube end part, and flange adopts bolt to connect between each member, processing, easy for installation; This type of flange can use in fields such as steel tube tower in electric transmission line, communication steel tube tower, TV steel tube towers.

Embodiment
As shown in Figure 2, offer hole 2 on the flange plate 1, flange plate 1 offers bolt connecting hole 3 along circumference, is provided with flange neck tube 4 on flange plate 1 card on 2 sides, hole, and flange plate 1 can be an one-piece element with flange neck tube 4, also can be that two interconnective parts constitute; Flange plate 1 is the one-piece element that forges with flange neck tube 4 in the present embodiment.
As shown in Figure 2, the shape that the end face 9 of flange neck tube 4 promptly is used for the part that is welded to connect with pipe fitting is continuous concaveconvex shape, and described continuous concaveconvex shape can be a kind of in waveform, sinusoidal waveform, arc, profile of tooth or the zigzag fashion; In the present embodiment, the shape of the end face 9 of flange neck tube 4 is sinusoidal waveforms, as shown in Figure 3.Concaveconvex shape also can be circular arc and rectilinear combination; It is the combination of profile of tooth and arc.
This flange is connected as shown in Figure 4 with pipe fitting, steel pipe 8 is inserted use two fillet weld weld all arounds to connect in the waveguide flange, promptly adopts end face 9 welding of fillet weld 5 with the tube wall and the waveguide flange neck 4 of steel pipe 8; Adopt the hole 2 inwalls welding of fillet weld 6 with the end face and the flange plate 1 of steel pipe 8; The dotted portion of fillet weld 6 in pipe.
This flange can dock steel pipe 8 as shown in Figure 5 with being connected also of pipe fitting with waveguide flange, adopt butt weld 7 that steel pipe 8 pipe end faces are docked welding with the end face 9 of waveguide flange neck 4.
Claims (2)
1. break-resistant wave-shaped flange, it comprises flange plate, flange plate is provided with the flange neck tube, it is characterized in that it is continuous concaveconvex shape that the neck flange pipe is used for the outer end surface shape that connects welding.
2. break-resistant wave-shaped flange according to claim 1, the combination of one or more that it is characterized in that described neck flange pipe to be used for the outer end surface shape that connects welding be waveform, sinusoidal waveform, arc, profile of tooth or zigzag fashion.
