  However, in the above-described conventional technology, when the pipe body and the ridge are joined with the sealing material, the seal breakage occurs due to the aging of the sealing material, and water leaks from the joint between the pipe body and the ridge (the rain gutter seam). There was a problem that it might occur.

  Moreover, when joining a pipe body and an eaves part by welding, since a welding operation is performed from the side where a pipe body extends to a ridge, a pipe body becomes an obstruction and a welding operation is restrict | limited. Therefore, there has been a problem that it is difficult to ensure the watertightness of the joint between the tubular body and the gutter (junction of the gutter).

  The present invention has been made in order to solve the above-described problems. A railway vehicle structure that can prevent water leakage due to a seal break from a joint of a rain gutter and can secure the water tightness of the junction of the gutter. The purpose is to provide.

Means for Solving the Problems and Effects of the Invention

In order to achieve this object, according to the railway vehicle structure of the first aspect, the wife structures are arranged at both longitudinal ends of the railway vehicle, and the wife structures are connected by the side structures. A roof structure is disposed above the side structures and the wife structure, and rainwater that falls on the roof structure is guided downward by the pipe body. A predetermined member is connected to the downstream end of the tubular body. As a member that communicates with the downstream end of the tubular body through the predetermined member, a ridge is disposed along the vertical direction of the wife structure, and a plate-like first standing upward from a part of the upper end of the ridge. The installation part is erected. A through hole is formed in the thickness direction between the one surface and the other surface of the first standing portion, and the tubular body and the predetermined member are connected to rainwater from the one surface side of the first standing portion via the through hole. Is introduced.

Jo Tokoro members, the welding operation is performed from the other side of the first erected portion is bonded to the first standing portion by the weld metal melted solidified. Since Jo Tokoro members are arranged on one side of the first standing portion (the surface opposite to the surface on which the welding operation is performed), the welding work Tokoro constant member is made from the other surface side of the first standing portion It is difficult to become an obstacle. As a result, it is possible to prevent the welding operation from being restricted, and thus it is possible to ensure the watertightness of the gutter junction. Further, Jo Tokoro members, since it is joined to the first standing portion by welding a metal, there is an effect that can prevent water leakage due to seal out from seam gutter occurs.
According to the railway vehicle structure of the second aspect, the pipe body is welded from the other surface side of the first standing portion, and is joined to the first standing portion by the molten and solidified weld metal. Since the tubular body is arranged on one surface side of the first standing portion (the surface opposite to the surface on which the welding operation is performed), the tubular body becomes an obstacle to the welding operation performed from the other surface side of the first standing portion. hard. As a result, it is possible to prevent the welding operation from being restricted, and thus it is possible to ensure the watertightness of the gutter junction. Further, since the pipe body is joined to the first standing portion by the weld metal, there is an effect that it is possible to prevent water leakage due to a seal break from the joint of the rain gutter.

According to the railway vehicle structure of the third aspect , the wall forming portion is constituted by a member different from the first standing portion and has a surface facing the other surface of the first standing portion. Since the wall forming portion is attached to the remaining portion at the upper end of the ridge, the other surface of the first standing portion is exposed in a state where the wall forming portion is removed. Thereby, welding from the other surface side of the first standing portion can be facilitated. After the welding operation is performed from the other surface side of the first standing portion and the pipe body or the predetermined member is joined to the first standing portion, the wall forming portion is attached to the remaining portion at the upper end of the flange. In addition to the effect of claim 1 or 2 , rainwater that has flowed from the tubular body to the through hole is introduced into the reed by configuring the first standing part and the wall forming part at a part of the upper end and the remaining part of the reed. It is possible to prevent leaking.

According to the railway vehicle structure of the fourth aspect, the flange (predetermined member) formed in a bowl shape with respect to the downstream end of the tubular body is brought into contact with one surface of the first standing portion, and penetrates the end surface of the flange. The inner circumference of the hole or the other surface of the first upright portion is joined by weld metal. When welding the end face of the flange and the inner circumference of the through hole or the other face of the first standing part from the other face side of the first standing part, the entire circumference of the end face of the flange is taken along the inner circumference of the through hole. It can be easily welded. Further, the protruding width of the end face of the flange can be used as an adjustment margin for positional deviation with respect to the through hole. Thereby, in addition to the effect of Claim 1 , there exists an effect which can perform a welding operation easily.

According to the railway vehicle structure of claim 5, the water collector (predetermined member) interposed between the downstream end of the tubular body and the through hole of the first standing portion is connected to the downstream end of the tubular body. Is done. A flange is formed at the tip of the water collector, and the flange is in contact with the first standing portion. The rear end of the water collector is formed with a first opening to which the downstream end of the pipe body is connected and a second opening to which the downstream end of another drain pipe is connected. In addition, wastewater from another drain pipe can also be collected in the water collector. Since the water collector is provided with a bottom portion that is inclined downward from the rear end portion toward the front end portion, waste water (including rainwater) collected in the water collector can be guided from the bottom portion to the eaves. Thereby, in addition to the effect of Claim 1, it has the effect that the waste_water | drain which generate | occur | produces not only the rain water which fell on the roof but a railway vehicle can be drained from a fence.

According to the railway vehicle structure of claim 6 , the plate-like second standing portion is erected upward from a part of the upper end of the eaves and is continuously connected to the first erected portion, and the wall forming portion Since it is composed of a member different from the first standing portion and the second standing portion, the wall forming portion can be reduced in size and weight as compared with a railway vehicle structure in which the second standing portion is not formed. . Since the wall forming part is attached to the upper end of the hook after connecting the pipe body to the hook, if the wall forming part can be reduced in size and weight, the man-hours for mounting the wall forming part can be reduced, and as a result the assembly of the wife structure Work can be reduced. As a result, in addition to the effect of the third aspect , there is an effect that the number of assembly work steps of the railway vehicle structure can be reduced.

According to the railcar structure according to claim 7 , the wife structure includes a pair of corner pillars that are coupled to the both sides of the wife outer plate in the width direction and to the longitudinal ends of the side structure. The corner pillar is equipped with a collar. In addition to the effect of the sixth aspect , the corner pillar has the effect of reducing the number of parts.

Further, since the first standing portion is erected on the surface facing the other corner pillar, one surface of the first standing portion erected on the pair of corner pillars is opposed to each other, and the other The surface can be turned outward. As a result, in addition to the effect of the sixth aspect, there is an effect that the welding work from the other surface side of the first standing portion can be facilitated.

Further, since the second standing portion is connected to the first standing portion and standing on the side structure side, the side structure can be connected to the second standing portion. Thereby, in addition to the effect of Claim 6 , there exists an effect which can make the assembly operation | work of a railway vehicle structure easy.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described with reference to the accompanying drawings. First, with reference to FIG. 1, the railway vehicle structure 1 in one embodiment of the present invention will be described. FIG. 1 is a rear view of the wife structure 3 of the railway vehicle structure 1 (viewed from the cabin side). In FIG. 1, a part of the wife structure 3 in the height direction is not shown.

  As shown in FIG. 1, the railway vehicle structure 1 includes a wife structure 3 that is erected at both front and rear ends of the frame 2, and a side structure (not shown) that is erected at both left and right ends of the frame 2. The side structure and the roof structure 4 disposed on the upper part of the wife structure 3 are configured. The wife structure 3 includes a wife outer plate 5 formed by an inverted U-shaped plate member when viewed from the front, a pair of corner columns 6 connected to both sides of the wife outer plate 5, and a space between the corner columns 6. And a girder 7 to be installed.

  The corner pillar 6 is a member formed in a hollow prismatic shape as described later, and is configured such that the lower end thereof reaches the lower surface of the underframe 2. In the present embodiment, as will be described later, since the ridge 6b (see FIG. 2 (a)) is built in the corner column 6, rainwater introduced into the corner column 6 (竪 樋) It is led to the bottom and drained. The girder 7 has a recess 7a that communicates with a gutter (not shown) disposed on the roof structure 4. The receiving part 7a is a part for guiding rain water flowing through the rain gutter (side) of the roof structure 4 to the wife structure 3, and a metal pipe 8 (elbow pipe) is connected to the opening at the bottom of the receiving part 7a. ing.

  The pipe body 8 is a member for guiding rainwater to the corner column 6 (竪 樋), is curved from the upstream end to the downstream end, and the downstream end is arranged facing the outside (the corner column 6 side). A water collector 10 is connected to the downstream end of the tube body 8, and the tube body 8 introduces rainwater into the corner column 6 (竪 樋) via the water collector 10.

  The water collector 10 is a box-shaped member for collecting rainwater and guiding it to the corner pillar 6 (６), and a drain pipe 9 is connected separately from the pipe body 8. The drain pipe 9 is a straight pipe disposed on the wife outer plate 5 so as to be inclined downward from the approximate center of the wife structure 3 to the outside (corner column 6 side). In this embodiment, an air conditioner (not shown) is used. Is connected to the upstream end. Thereby, not only rainwater but also drainage generated by the railway vehicle can be drained from the corner pillar 6 (６). The upstream end 9 a of the drain pipe 9 is attached to an attachment member 5 a fixed to the end face plate 5.

  Next, the wife structure 3 and the corner post 6 will be described in detail with reference to FIG. FIG. 2A is a plan view of the shoulder portion of the wife structure 3, and FIG. 2B is an enlarged plan view of the corner column 6. 2, the right side (right side of FIG. 1) of the wife structure 3 will be described. As shown in FIGS. 2 (a) and 2 (b), the corner column 6 disposed at the end of the wife structure 3 is formed in a hollow prism shape, and the outer shape is substantially square when viewed from above. It is formed into a shape. In the present embodiment, the first standing portion 20 and the second standing portion 21 are erected as a part of the corner pillar 6.

  The corner column 6 is partitioned by connecting a substantially T-shaped partition wall 6 a to the inner wall of the corner column 6 in plan view. As a result, a plurality of pipelines along the longitudinal direction of the corner column 6 can be formed inside the corner column 6. A substantially triangular closing plate 22 in plan view is fixed to the upper end of the substantially T-shaped partition wall 6 a while being in close contact with the first standing portion 20 and the second standing portion 21. Almost half of the pillar 6 is blocked. Since the partition wall 6a and the blocking plate 22 are provided, the rigidity of the corner post 6 can be increased, and a pipe line that is not blocked by the blocking plate 22 can be used as the ridge 6b. Thereby, since the eaves 6b are built in the corner pillar 6, it is not necessary to provide an eaves separately from the corner pillar 6, and the internal space of the railway vehicle structure 1 can be used effectively. In addition, the number of parts can be reduced as compared with the case where a collar is provided separately from the corner post 6.

  A plate-like first standing portion 20 is erected upward from a part of the upper end via a closing plate 22 from the flange 6b. In the present embodiment, the first standing portion 20 is integrally formed on the side of the beam 7 as a part of the corner column 6, and the beam 7 is provided between the first standing portions 20 formed on the left and right corner columns 6. It is erected. As for the 1st standing part 20, the through-hole 20a is penetrated and formed in the thickness direction of one surface (FIG. 2 (a) left) and the other surface (FIG. 2 (a) right). By connecting the water collector 10 to the first standing portion 20 and communicating with the through hole 20a, drainage water such as rainwater introduced into the water collector 10 is guided to the corner pillar 6 through the through hole 20a. . Since the closing plate 22 is disposed at the upper end of the partition wall 9a, the drainage flows on the closing plate 22 and flows into the trough 6b.

  A plate-like second standing portion 21 connected to the first standing portion 20 is erected from the upper end of the flange 6b via a closing plate 22 from a part of the upper end. In the present embodiment, the second standing portion 21 is integrally formed on the side structure 40 side as a part of the corner post 6. Since the second standing portion 21 is connected to the first standing portion 20 substantially orthogonally and is integrally formed with the first standing portion 20, the first standing portion 20 and the second standing portion 20 are formed. The mechanical strength of the portion 21 can be ensured.

  FIG. 2C is a rear view of the shoulder portion of the wife structure 3. As shown in FIG. 2 (c), the second standing portion 21 is formed in a substantially fan-like shape that is vertically long when viewed from the back, and the outer shape formed in an arc shape is smoothly communicated to the beam 7 and the circle A part of the arcuate outer shape is provided with a cutout portion 21a cutout on the inside. The reason why the second standing portion 21 is formed in the shape as described above is to match the shape of the side structure 40 described later.

  The water collector 10 is a rectangular tube-shaped member for connecting the through-hole 20 a formed through the first standing portion 20, the pipe body 8 and the drain pipe 9, and the downstream end 8 b of the pipe body 8. And between the downstream end 9 b of the drain pipe 9 and the through hole 20 a formed in the first standing portion 20. In the water collector 10, the downstream end 8 b of the pipe body 8 and the downstream end 9 b of the drain pipe 9 are connected to the rear end portion 12, and a flange 11 is formed at the tip portion. Since the bottom portion 10a of the water collector 10 is inclined downward from the rear end portion 12 toward the flange 11 (tip portion), the drainage (including rainwater) introduced into the water collector 10 is flange 11 (tip portion). Descent toward

  FIG.2 (e) is sectional drawing of the wife structure 3 in the IIe-IIe line | wire of FIG.2 (c). As shown in FIG. 2 (e), the rear end portion 12 is constituted by a substantially rectangular plate member, and the first opening 12a through which the downstream end 8b (see FIG. 2 (c)) of the tubular body 8 is inserted. And the 2nd opening 12b in which the downstream end 9b of the drainage pipe 9 is penetrated is arranged in parallel by the upper and lower sides of the rear-end part 12. As shown in FIG. Since the 1st opening 12a and the 2nd opening 12b are arranged in parallel at the upper and lower sides of the rear-end part 12, the width | variety (FIG. 2 (a) up-down direction) of the water collector 10 can be narrowed, and the tubular body 8, A trough comprising the drain pipe 9 and the water collector 10 can be accommodated in the wife structure 3 in a compact manner.

  Returning to FIG. The flange 11 is a member formed in a bowl shape with respect to the downstream end 8 b of the tube body 8, and the water collector 10 is brought into contact with the first standing portion 20 through the flange 11. In the present embodiment, the flange 11 is not formed so as to protrude evenly with respect to the water collector 10, but is formed so as to protrude in a downward direction from the water collector 10. By suppressing the amount of upward protrusion of the flange 11 with respect to the water collector 10, the water collector 10 can be fixed close to the lower surface of the girder 7, so that the space under the girder can be used effectively. Moreover, the height of the through-hole 20a can be made low with respect to the bottom face 10a of the water collector 10 by disposing the flange 11 below the water collector 10. Thereby, it can drain smoothly from the water collector 10 to the through hole 20a.

  FIG. 2D is a side view of the shoulder portion of the wife structure 3. As shown in FIG. 2D, the through hole 20a formed through the first standing portion 20 is formed in a substantially rectangular shape, and the outer shape of the flange 11 and the inner hole portion 11a of the flange 11 are also through holes. It is formed in a substantially rectangular shape corresponding to 20a. The through hole 20a formed in the first standing part 20 and the flange 11 are water-tight welded to the entire circumference of the through hole 20a by the welded and solidified metal 23, and the flange 11 and the first standing part 20 are joined. . The welding of the first upright portion 20 and the flange 11 is not performed from the first surface side (inside the wife structure 3) of the first upright portion 20 where the water collector 10 is disposed, but the opposite thereof. It is performed from the surface side (side surface side of the wife structure 3).

  Here, in order to perform watertight welding, it is necessary to keep the welding posture stable and to secure the angle of the torch (welding device), but welding is performed from the side surface side of the end structure 3 (FIG. 2 (d) paper surface side). Thereby, it can prevent that welding operation is restrict | limited to the water collector 10 and the pipe body 8. FIG. As a result, since the welding posture can be maintained, watertight welding can be performed stably, and the watertightness of the joint between the water collector 10 and the first standing portion 20 can be ensured. As a result, it is possible to reliably prevent drainage from leaking.

  The through-hole 20a formed through the first standing portion 20 has a substantially rectangular shape, and the outer shape of the flange 11 and the hole 11a inside the flange 11 are also formed in a substantially rectangular shape. Since the through-hole 20a and the flange 11 have upper and lower edges arranged in a substantially horizontal direction (FIG. 2 (d) left and right direction) and left and right edges arranged in a substantially vertical direction (FIG. 2 (d) up and down direction). The alignment between the flange 11 and the through hole 20a can be facilitated.

  That is, if the left and right protrusion widths of the flange 11 are secured, the flange 11 and the through hole 20a can be independently aligned in the left and right directions. Thereby, since alignment with the flange 11 and the through-hole 20a can be made easy, watertight welding can be performed reliably.

  Further, the protrusion width in the vertical direction of the flange 11 is set larger than the protrusion width in the left-right direction. Thereby, the adjustment margin of the up-down direction which concerns on alignment with the flange 11 and the through-hole 20a can be made larger than the adjustment margin of the left-right direction. Since the vertical alignment between the flange 11 of the wife structure 3 and the through-hole 20a affects the water gradient of the tube 8 and the water collector 10, the tube can be secured by sufficiently securing the vertical adjustment allowance. 8 and the water collector 10 can secure the water gradient, and the drainage performance of the soot can be secured.

  A joining method for joining the tubular body 8 and the water collector 10 configured as described above to the wife structure 3 will be described. First, the water collector 10 to which the flange 11 and the rear end portion 12 are fixed is temporarily fixed to the wife structure 3, and the pipe body 8 and the drain pipe 9 are temporarily fixed to the wife structure 3. Then, the pipe body 8 and the drain pipe 9 are temporarily welded to the rear end portion 12. After the temporarily welded pipe body 8, drain pipe 9, and water collector 10 are removed from the end structure 3, the pipe body 8, drain pipe 9, and water collector 10 (rear end portion 12) are watertight welded. A water collector 10 in which the pipe body 8 and the drain pipe 9 are watertightly welded is attached to the end structure 3, and watertight welding is performed between the pipe body 8 and the receiving part 7a, and between the flange 11 and the first standing part 20. . Thereby, the path | route (導 く) which guides the rainwater guide | induced to the cage | basket 6a can be formed in the wife structure 3. FIG.

  Next, with reference to FIG. 3, the joining of the first standing portion 20 and the water collector 10 when the second standing portion 21 is erected will be described. FIG. 3A is a perspective view schematically showing the water collector 10 joined to the first standing portion 20, and FIG. 3B is a first view taken along line IIIb-IIIb in FIG. It is sectional drawing of the standing part 20 and the water collector 10, FIG.3 (c) is the perspective view which showed typically the water collector 110 joined to the 1st standing part 20, FIG.3 (d). ) Is a cross-sectional view of the first standing portion 20 and the water collector 110 taken along line IIId-IIId in FIG. In addition, in Fig.3 (a) to FIG.3 (d), the shape of the water collector 10 is typically illustrated in the straight tube shape.

  As shown in FIG. 3A and FIG. 3B, in the present embodiment, the second upright portion 21 is connected to the first upright portion 20 so as to be orthogonal to the first upright portion. When the water collector 10 (flange 11) is welded to the portion 20, the welding operation may be restricted by the second standing portion 21 depending on the distance between the second standing portion 21 and the through hole 20a. That is, when watertight welding is performed on the entire periphery of the edge of the through hole 20a, there is a possibility that the watertightness of the weld near the second standing portion 21 is incomplete.

  In the present embodiment, after the flange 11 is brought into contact with the first standing portion 20, the surface opposite to the surface of the first standing portion 20 with which the flange 11 is brought into contact (from the lower side in FIG. 3B). Welding is performed, and the first standing portion 20 and the flange 11 are joined by the weld metal 23 melted and solidified between the flange 11 and the through hole 20a or the first standing portion 20. Thereby, even if the 2nd standing part 21 is standing in the vicinity of the through-hole 20a, watertight welding is performed on the entire circumference of the through-hole 20a without being interfered by the second standing part 21. be able to.

  On the other hand, as shown in FIG. 3C and FIG. 3D, the water collector 110 is inserted into the through hole 20 a formed in the first standing portion 20, and the water is collected in the first standing portion 20. In the case where the water collector 110 is penetrated, the water collector 110 and the first standing portion 20 are connected by the weld metal 123 melted and solidified between the outer peripheral wall of the water collector 110 and the first standing portion 20. Be joined. When the space | interval of the 2nd standing part 21 and the water collector 110 is narrow, the 2nd standing part 21, the water collector 110, and a welding apparatus (not shown) interfere, and the 2nd standing part 21 and a water collecting device are collected. There is a possibility that the watertight welding with the water vessel 110 may be incomplete. Moreover, even if welding can be performed, workability may be lacking. As in the present embodiment, by performing welding between the flange 11 formed in the shape of a bowl and the first standing portion 20, it is possible to suppress these and perform stable watertight welding.

  Next, the wall formation part 30 is demonstrated with reference to FIG. The wall forming portion 30 is a member for guiding the drainage discharged from the through hole 20a of the first standing portion 20 to the trough 6b without leakage. That is, in the state where the flange 11 is welded to the first standing portion 20 as shown in FIG. 2D, when the drainage is discharged from the through hole 20a vigorously, the drainage is not introduced into the trough 6b. Jump out. In order to prevent this, after welding the flange 11 to the first standing portion 20, the wall forming portion 30 is attached to the upper end of the flange 6b, and the first standing portion 20, the second standing portion 21, and the wall The kite is completed by the forming unit 30 and the kite 6b. 4A is a rear view of the wall forming portion 30, and FIG. 4B is a plan view of the wall forming portion viewed from the direction of the arrow IVb.
