Abstract
The invention discloses a break-resistant wave-shaped flange comprising a flange plate on which a flange neck pipe is arranged, and the flange neck pipe is used for connecting and welding an end surface in a continuous concave-convex shape. The break-resistant wave-shaped flange avoids the welding defects of the traditional flat-welding hub type flange and the but-welding hub type flange and the problem that welding head influences the annular centralization of a domain, can effectively prevent steel pipe ports from simultaneously breaking and effectively improve the safety reliability of steel pipe nodes and iron tower members; the wave-shaped flange is welded at the end of one steel pipe, and the flanges among the members are welded by bolts, thereby the break-resistant wave-shaped flange has convenient processing and installation; and the flange can be used in the fields of transmission line steel pipe towers, communication steel pipe towers, television steel pipe towers and the like.
Description
Technical field
The invention belongs to steel pipe shaft tower parts, have and relate to a kind of steel pipe shaft tower pipe fitting flange connecting that is used for.
Background technology
Steel pipe shaft tower circuit uses widely in the 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 structure 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 intensity of this section descend, 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.
(3) welding heat affected zone of circumferential weld concentrate on same section circumferential weld around, the fragility of these same section heat affected zone steel increases greatly, occurs the brittle fracture phenomenon easily.
Because the defective of said structure in the actual use of steel pipe shaft tower, the accident of the pipe fitting junction fracture in the steel pipe shaft tower occurred, causes tremendous loss.
Summary of the invention
The object of the present invention is to provide a kind of break-resistant wave-shaped flange that can avoid the pipe fitting junction fracture in the steel pipe shaft tower, to address the above problem.
Technical scheme of the present invention is: break-resistant wave-shaped flange, and it comprises flange, and flange 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 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 invention 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 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 area of dissipation, is example with the weld seam of unit length, and the area of dissipation of girth joint is rectangular, and the area of dissipation of wave mode weld seam is disperse fan-shaped; Secondly, the wave mode weld seam is easy to the weld defect that staggers, and avoids the annular of weld defect to concentrate; The 3rd, the wave mode weld seam has increased fusion length, has strengthened the bonding strength of steel pipe and flange; The present invention has avoided the weld defect 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.

The specific embodiment
As shown in Figure 2, offer hole 2 on the flange 1, flange 1 offers bolt connecting hole 3 along circumference, is provided with flange neck tube 4 on flange 1 card on 2 sides, hole, and flange 1 can be a global facility with flange neck tube 4, also can be that two interconnective parts constitute; Flange 1 is the global facility 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; 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 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, flange 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.
