The specific embodiment
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.
The present embodiment be take one of flat steel pipe node supervisor, and two arms are installed is example, and as shown in Figure 1, the Steel Tube Joint that the utility model embodiment provides comprises: supervisor 1, upper arm 2, lower branch line 3, backing plate 4.Backing plate 4 is the arc of fitting with supervisor's 1 radian, the radian that backing plate 4 covers supervisor 1 is between 90 °～360 °, and the welding space, end of arm 2 and lower branch line 3 can be provided, and can be the arc of 90 °, 120 °, 150 °, 180 °, 210 °, 240 °, 270 °, 300 °, 330 ° or 360 °; Backing plate is that stepped construction is divided into upper strata backing plate and lower floor's backing plate, lower floor's backing plate and supervisor's 1 laminating, and upper arm 2 and lower branch line 3 run through upper strata backing plate and are connected with lower floor backing plate, and upper strata backing plate and lower floor backing plate can be that to weld can be also that bolt is connected.Upper arm 2 welds or is connected with bolt with the top edge of backing plate 4, lower branch line 3 welds or is connected with bolt with the lower limb of backing plate 4, backing plate 4 can weld with supervisor 1, also can connect with bolt, the axis of upper arm 2 and lower branch line 3 respectively with supervisor's axes intersect of 1, arm 2 and arm 3 and supervisor's 1 angle is respectively between 30 °～150 °, and arm 2 and arm 3 can be 30 °, 45 °, 60 °, 75 °, 90 °, 105 °, 120 °, 135 ° or 150 ° with supervisor 1 angle.
Wherein, supervisor 1 is steel pipe with arm 2 and arm 3, and preparation is responsible for 1 material and is by weight percentage, C:0.15%, Mn:1.46%, Si:0.33%, P:0.022%, S:0.023%, V:0.17%, Nb:0.048%, Ti:0.14%, Cr:0.28%, Ni:0.39%, iron is surplus.
The Steel Tube Joint that the present embodiment provides has been improved upper arm 2 and lower branch line 3 and supervisor's 1 connected mode, has avoided the welding condition of traditional connected mode limited, and weldquality cannot guarantee, stressed concentrate and inhomogeneous, is out of shape the shortcomings such as larger; And conventional steel node usually needs extra interpolation stiffening rib, steel using amount, man-hour, weld seam and front face area have been increased.
The Steel Tube Joint that the present embodiment provides has significantly improved stress and the load-carrying properties of Steel Tube Joint, and upper arm 2 and lower branch line 3 are welded on arc backing plate 4, rather than is directly welded on supervisor 1, has increased welding space, thereby has more easily guaranteed weldquality; The active force of upper arm 2 and lower branch line 3 is delivered to supervisor 1 by arc backing plate 4, rather than directly by arm section, transmits, and power transmission area is very large, and load is evenly distributed in supervisor's 1 plane, has alleviated stressed concentrated unfavorable factor, reduces column joints deformation; Arc backing plate 4 is fixed on supervisor 1, and contact area is large, stressed even, has increased the integral rigidity of node simultaneously, has improved the load threshold of Steel Tube Joint generation cripling, has improved integrated carrying ability; The improvement of stress, has further reduced the use of stiffening rib, thereby has reduced more weld seam, front face area and welding job that stiffening rib brings.
Tradition iron tower of power transmission line Steel Tube Joint, as shown in Fig. 2 to Figure 21; The reinforcement measure of tradition iron tower of power transmission line Steel Tube Joint adopts welding stiffening rib, to strengthen node rigidity, reduces stress and concentrates, but increased a large amount of weld seams, as shown in figure 22; Tradition iron tower of power transmission line Steel Tube Joint force analysis, as shown in figure 23, conventional steel tubular joint unbalance stress is too concentrated; The force analysis of tradition iron tower of power transmission line Steel Tube Joint welding stiffening rib, as shown in figure 24, conventional steel is passed through weldering node mutually, adds after a large amount of stiffening ribs, but still can not improve well stressed concentrated shortcoming.
The Steel Tube Joint that the present embodiment provides is applicable to steel tube tower in electric transmission line or other are subject to the steel work (bridge, tower mast, Long Span Roof etc.) of the steel pipe connection that load is larger, can significantly improve the stressed of Steel Tube Joint, and still can adopt the mode of conventional interpolation stiffening rib further node to be reinforced, thereby improve the supporting capacity of node.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit, although the utility model is had been described in detail with reference to above-described embodiment, those of ordinary skill in the field are to be understood that: still can modify or be equal to replacement the specific embodiment of the present utility model, and do not depart from any modification of the utility model spirit and scope or be equal to replacement, it all should be encompassed in the middle of claim scope of the present utility model.
