Fig. 2 represents the structure of general rail.Shape, specification and the structure of rail rail body, wherein, the rail height represents that with H the flange of rail is wide to be represented with B, and rail head is wide to be represented with b, and the web of the rail is wide to be represented with t.The two ends of general rail are flush end.
With reference to Fig. 3 to Fig. 6, rail is the rail bar 1 of strip, rail bar 1 comprises rail head 11, the web of the rail 12, the flange of rail 13, an end of rail is cut half, so, side at the center line 3 of end of rail forms joint 2, if the tieing of rail one end is 2P, tieing 2P comprises half rail head 21A, half web of the rail 22A, half flange of rail 23A, The midsagittal plane 24, opposite side at the The midsagittal plane 24 of joint 2P is the position, joining space 25 of another same tip 2Q, at the opposite side of center line half rail head interface 21B, half web of the rail interface 22B, half flange of rail interface 23B is arranged.With reference to Fig. 6, another end of rail also cuts half, and formed joint 2Q and joint 2P establish the right side of joint 2P at center line 3 respectively in the both sides of center line 3, and then joint 2Q is in the left side of center line 3; Like this, even the rail tune, joint 2 is always on the right side of center line 3, and rail does not have the side tropism, so produce the unnecessary operation of rail tune at the Shi Buhui that lays a railway track, makes and lays a railway track fast.Perhaps with reference to Fig. 7 to Figure 10, the Left elevation is same with right elevation of rail, homology of right view figure and main view figure is established the left side of joint 2P at center line 3, and then joint 2Q in like manner makes and lays a railway track fast on the right side of center line 3.Fig. 3 indicate X, Z axle again Fig. 4 indicate the Y-axis rectangular co-ordinate.
With reference to Fig. 5, the wide t of the web of the rail of half web of the rail
1Equal t/2.
With reference to Figure 11, rail 1a and rail 1b overlap (joining) mutually, overlap mutually with reference to Figure 11,12, two sections rail with identical joint 2, and joint 2P and 2Q overlap joint are taken mouth 4 for X-axis.
Must satisfy following two requirements during installation: interface size L is more than or equal to the rail gap of prior art; Must reserve overlap joint size a, to satisfy the strength and stiffness requirement of overlap joint mouth.Two overlap joint rail 1a and 1b, the flange of rail of rail 1a end face is wide, rail head is wide and the web of the rail is wide all cuts half, and cutting length is L+a, and the flange of rail of rail end face is wide, rail head is wide and the web of the rail is wide all cuts second half, and cutting length is L+a.
Here there are two problems: the one, because the wide t of the web of the rail
1Have only t/2, thus dangerous, be necessary to strengthen the web of the rail; The 2nd, if the joint at rail 1a two ends as shown in figure 12, the same side that joint 2P and 2R are positioned at center line 3 can produce the side tropism, promptly, when rail 1a tune, joint 2P and 2R then are positioned at the opposite side of center line 3, lay a railway track like this and often need reverse end for end rail, and the speed of laying a railway track is slow.
As seen the rail 1a among Figure 12 has the side tropism and rail among Fig. 6 does not have the side tropism.
With reference to Fig. 6, Figure 13 and Figure 14, the joint 2P of each one steel rail and joint 2Q divide the both sides that are listed in center line 3, so whole one steel rail does not have the side tropism, can get any end of an one steel rail 1a and the end overlap joint of rail 1c arbitrarily in a pile rail.Like this, lay a railway track rapidly.
In the time need establishing joint 2 in the end of rail, other has manufacture method, for example:
To shown in Figure 20, one section other end with short rail 1a of joint 2 is a flush end as Figure 15, and its flush end is connected with the flush end of long rail 01.When jointed track is transform as gapless track or when solving the circuit that rail head damages, need not change whole one steel rail.Respectively cut one section short rail in the rail gap both sides of the rail of having laid, put into short rail 1a, the 1b of two sections mutual overlap joints shown in Figure 15 to 20.Since this short rail can be hand held in tune easily, so can lay fast.
With reference to Figure 21,22 and 23, the flush end of short rail 1a, 1b is close to the flush end of long rail 01A, 01B respectively, these seam 5 places do not establish seam line L, if the short rail 1b among Figure 22 along X-axis Rotate 180 degree and with Figure 21 in short rail 1a overlap joint, if clamping plate 07A is positioned at the left side of long rail 01A, short rail 1a, short rail 1b, long rail 01B, then clamping plate 07B is positioned at the right side, respectively has one group of nut 05 and bolt 06 fixing in the both sides of taking mouth 4.The E-E cross section is identical with the position in A-A cross section, and only different is, in Figure 23, and the wide t of the web of the rail
2Be equivalent to t/2 and add the wide of clamping plate 07A, and also have clamping plate 07B also to strengthen the intensity and the stiffness of the web of the rail.In addition, if as shown in Figure 6 long rail overlap joint more than two, one group of nut 05 of 07 needs of clamping plate and bolt 06 can be by prior art fixed length rail 1a, 1b.
With reference to Figure 23 to 25, the wide t of the web of the rail
2For: t2＞t/2.Best, the wide t of the web of the rail
2For: t
2＞b/7.The best wide t of the web of the rail
2For, 17mm 〉=t
2〉=12mm.Relax the size of the web of the rail in mould, make the long rail that the web of the rail is widened by the prior art hot rolling, crosscut is slit into segment, is cut into the short rail shown in Figure 15 to 20 again.
