  When the support members 50 and 100 are installed at predetermined positions as described above, the prepared level crossing plates 2 and 3 are connected to the back side of the top plate 10 or 30, that is, the beam member 11 or the beam members 31 and 32. It is fitted between the rails 6 and 6 or between the rail 6 and the road surface end 7 with the attached surface facing downward. At this time, the railroad crossing plate 2 is fitted in a posture along the short side of the top plate 10, that is, the beam members 11, 11 along the direction in which the rails 6, 6 extend. Here, the railroad crossing plate 2 has the length of the railroad crossing plate 2, that is, the distance between the tips of the L-shaped fixing plates 13 and 13 protruding from both ends in the long side direction of the top plate 10 is the head of the rails 6 and 6. The distance between 6a and 6a is substantially the same. Therefore, as shown in FIG. 11, the railroad crossing plate 2 can be fitted between the rails 6 and 6 (within the gauge) simply by dropping from above the rails 6 and 6 straight down.

  When the railroad crossing plate 2 is fitted between the rails 6 and 6, as shown in FIG. 2, an L-shaped fixing plate attached to the beam member 11, with the sleeper 5 crossing just below the center in the short side direction of each top plate 10. The 13 fixed portions 15 face the side surface 72 or the side surface 73 of the standing portion 52 of the support member 50 substantially in surface contact or with a slight gap therebetween. When the railroad crossing plate 2 is thus arranged in the gauge, the shaft insertion holes 74 provided in the standing portions 52 of the respective support members 50 and the fixing portions 15 are provided from the side of the railroad crossing plate 2. The long connecting shafts 19 and 19 are inserted over the insertion hole 15a. As shown in FIGS. 1 and 8, nuts 120 are attached to the ends of the connecting shafts 19, 19, and the installation of the level crossing plate 2 in the gauge is completed.

  The level crossing plate 3 is also laid in substantially the same manner as the above level crossing plate 2. More specifically, the railroad crossing plate 3 includes a rail member 6 in which the short side of the top plate 30 is along the direction in which the rail 6 extends and the beam member 31 fixed to the back side of the top plate 30 is shown in FIG. The beam member 32 faces the road surface end 7 side. The railroad crossing plate 3 is fitted from above so that the back surface of the top plate 30 (the surface on the fixed side of the beam members 31 and 32) faces the roadbed G side. Here, as described above, the edge member 105 is attached to the support member 100 in advance. Therefore, as shown in FIG. 11 by the arrow in FIG. 11, the railroad crossing plate 3 slightly tilts the end on the side where the beam member 32 is attached and pushes it below the edge horizontal portion 106 of the edge member 105. The end on the side where the beam member 31 is attached is pushed downward. As a result, the railroad crossing plate 3 is fitted between the rail 6 and the road surface end 7 arranged in parallel to the rail 6 (outside the gauge).

  When the railroad crossing plate 3 is arranged outside the gauge as described above, the sleeper 5 crosses just below the central portion in the short side direction of each top plate 30 as in the case of the railroad crossing plate 2. A state in which the rectangular fixing plate 34 attached to the beam member 31 fixed to the back surface side of the railroad crossing plate 3 is substantially in surface contact with the standing portion 52 of the supporting member 50 fixed to the rail 6 or has a slight gap. It will be in a state of facing each other. In addition, the rectangular fixing plate 34 attached to the beam member 32 is in substantially surface contact with the bearing portion 103 of the support member 100.

  When the railroad crossing plate 3 is thus arranged between the rail 6 and the road surface end portion 7, the shaft insertion hole 74 provided in the standing portion 52 of each support member 50 from the side of the railroad crossing plate 3 and The long connecting shaft 21 (shaft body) is inserted over the insertion hole 40 provided in each rectangular fixing plate 34 attached to the beam member 31. As a result, the end portion of the connecting shaft 21 protrudes from the standing portions 52, 52 of the support members 50, 50 arranged on both ends in the direction in which the rail 6 extends with respect to the railroad crossing plate 3. Nuts 120 are attached to both ends of the connecting shaft 21 as shown in FIGS.

  Further, there are railroad crossing plates in the shaft insertion hole 108 of the support member 100 fixed to the sleeper 5 and the shaft insertion hole 40 provided in the rectangular fixing plate 34 of the beam member 32 attached to the back side of the railroad crossing plate 3. The connecting shaft 22 is inserted from the side of 3. The connecting shaft 22 protrudes from the shaft insertion holes 108 and 108 of the support members 100 and 100 fixed to the sleepers 5a and 5c. Nuts 120 are attached to both ends of the connecting shaft 22 as shown in FIG. Thereby, the laying of the railroad crossing plate 3 outside the gauge is completed.

  As described above, in the railroad crossing structure 1, the support member 50 is arranged so that the base portion 51 passes under the rail 6, and does not float from the roadbed G. Moreover, the supporting member 100 is being fixed with respect to the sleeper tree 5, and does not float up from the roadbed G side. In the crossing structure 1 of the present embodiment, the beam member 11 fixed to the back surface of the crossing plates 2 and 3 and the shaft insertion hole 40 of the rectangular fixed plate 34 attached to the beam members 31 and 32 and the roadbed G do not float. Since the long connecting shafts 19, 21, 22 are inserted through the through holes 74 provided in the standing portions 52 of the support members 50, 100 fixed to the support members 50, 100, the railroad crossing plates 2, 3 are in the laid state. Does not rise. Further, the railroad crossing structure 1 is arranged by aligning the railroad crossing plates 2 and 3 at predetermined positions inside and outside the gauge, and by simply inserting and removing the connecting shafts 19, 21 and 22 from the side, Can be laid or removed.

  Further, in the crossing structure 1 described above, the L-shaped fixing plate 13 of the beam members 11, 31, and 32 in which the standing portion 52 of the supporting member 50 and the bearing portion 103 of the supporting member 100 are fixed to the crossing plates 2 and 3. The rectangular fixed plate 34 is arranged without a gap and is in a substantially surface contact state. Further, as described above, the support members 50 and 100 are fixed so that they cannot be moved relative to the rail 6 and the sleeper 5, respectively. Therefore, in the crossing structure 1 described above, the support member 50 and the support member 100 can also function as a stopper that prevents the crossing plates 2 and 3 from shifting in the direction in which the rail 6 extends.

  Since the crossing plates 2 and 3 described above are formed by arranging the three top plates 10 and 30 in the direction in which the rail 6 extends and connecting them with the beam members 11 and the beam members 31 and 32, they are integrated. The face plate 10 and the top plate 30 do not cause misalignment.

  Further, as described above, the railroad crossing plates 2 and 3 are fixed to the beam main bodies 12, 33 and 35 of the beam members 11, 31 and 32 by the bolts inserted from the surface side of the railroad crossing structure 1. Is. Therefore, the railroad crossing plates 2 and 3 can remove and fix only the top surface plates 10 and 30 that require maintenance or the like only by attaching and detaching bolts from the surface side.

  In the railroad crossing structure 1, the support member 50 fixed to the sleeper tree 5 and the support member 100 in the middle part of the railroad crossing structure 1 are hidden below the railroad crossing plates 2 and 3. Therefore, the railroad crossing structure 1 has a good appearance when laid. In the above embodiment, the support members 50 arranged at positions adjacent to both ends in the direction in which the rail 6 extends with respect to the railroad crossing structure 1 are exposed outside the railroad crossing plates 2 and 3. The support member 50 may be arranged at a position hidden under the railroad crossing plates 2 and 3.

  In the embodiment described above, the crossing plates 2 and 3 are both synthetic wood single plates made of the top plate 10 and 30, but the present invention is not limited to this, for example, the top plate 10 may be obtained by stacking and integrating another synthetic wood plate material on the front surface side or the back surface side of the steel plate 10, or by reinforcing a plate material made of a material different from the synthetic wood material. More specifically, the crossing plates 2 and 3 are, for example, plate bodies made of a material derived from synthetic wood obtained by compression molding synthetic wood pulverized into powder or chips, and generally FRP ( Fiberglass Reinforced Plastics), made of resin plates such as polycarbonate, metal plates such as aluminum and iron, so-called gypsum boards and asbestos straight boards, or a combination of these and synthetic wood It may be configured. Moreover, the top plate 10 or 30 may be a plate-like beam 131 fixed to the back side and reinforced, for example, like a top plate 130 (top surface portion) shown in FIG.

  Since the crossing plates 2 and 3 are made by fixing the steel beam members 11 and the beam members 31 and 32 to the back side of the top plates 10 and 30, the strength of the top plates 10 and 30 is high. Therefore, the level crossing described above can ensure the strength required for the level crossing structure 1 while reducing the thickness of the top plate 10, 30. Therefore, according to the above-described configuration, it is possible to reduce the weight of the level crossing plates 2 and 3 while suppressing the manufacturing cost of the level crossing plates 2 and 3 constituting the level crossing structure 1 to a minimum. Therefore, the railroad crossing structure 1 can easily lay the railroad crossing plates 2 and 3.

  As described above, in the crossing structure 1, since the top plates 10 and 30 are lightweight, there is a concern that the crossing plates 2 and 3 may be lifted. However, in the crossing structure 1, the top plates 10, 30 constituting the crossing plates 2, 3 are connected by the beam bodies 12, 32, 35 constituting the beam members 11, 31, 32. A certain amount of weight is secured as a whole. Further, in the railroad crossing structure 1, the shaft insertion holes 20 and 40 of the L-shaped fixing plate 13 and the rectangular fixing plate 34 fixed to the beam main bodies 12, 32 and 35, and the support members fixed to the rail 6 and the sleeper 5. The connecting shafts 19, 21, 22 are inserted over 50, 100. Therefore, the level crossing structure 1 does not cause the level crossing plates 2 and 3 to be lifted.

  In the crossing structure 1 described above, the beam member 11 and the beam members 31, 32 are fixed to the top plate 10, 30 using bolts inserted from the bolt insertion holes 10a, 30a provided on the surface side of the top plate 10, 30. It is supposed to be configured. Therefore, even if a situation occurs in which part of the three top plates 10, 30 constituting the railroad crossing plates 2, 3 is worn out and the like needs to be replaced, the bolts are attached / detached from the surface side of the top plates 10, 30. Thus, only the top plate 10, 30 that must be replaced can be replaced. Therefore, the railroad crossing structure 1 can easily perform maintenance involving replacement of the top plates 10 and 30.

  Here, in the crossing structure 1 described above, the shaft insertion holes 20 and 40 of the beam member 11 and the beam members 31 and 32 provided in the crossing plate 2 and the crossing plate 3 and the shaft insertion provided in the fixing members 50 and 100 are provided. Long connecting shafts 19, 21, 22 are inserted into the holes 74, 108 for connection. In the above configuration, since the beam members 11, 31, 32 are fixed so as to straddle the three top plates 10, 30, the crossing plates 2, 3 are unlikely to be bent, and the shaft insertion holes 20, 40 The alignment with the shaft insertion holes 74 and 108 can be performed relatively easily. However, if the level crossing plates 2 and 3 become large and bend, the positions of the shaft insertion holes 20 and 40 and the shaft insertion holes 74 and 108 may be displaced, and the level crossing connecting shafts 10, 21 and 22 may not be inserted well. There is.

  Therefore, when there is a concern about such a problem, the level crossing structure 1 is configured such that, for example, a part of the portion fixed by the support member 50 or the support member 100 is replaced with a fixing structure as shown in FIG. It is good also as a structure which can support the level crossing board 2 and 3 from the downward direction at the time of laying.

  More specifically, FIG. 13 illustrates a structure in which the railroad crossing plate 3 is laid using a support member 135 as shown in FIG. 13A in place of the support member 100 described above. Like the support member 100, the support member 135 is a member in which the horizontal portion 101 and the standing portion 102 are substantially orthogonal to each other, and the cross-sectional shape is substantially L-shaped, and stands with the horizontal portion 136a (base portion). This is a configuration in which a block-shaped support portion 136c is provided at a corner portion where the mounting portion 136b is abutted.

  In the fixing structure shown in FIG. 13, a beam member 137 is attached instead of attaching the beam member 32 to the back surface side of the top plate 30. The beam member 137 is a member corresponding to the beam main body 35 constituting the beam member 32, and is a member having a substantially “L” -shaped cross section in which the fixing portion 137a and the hanging portion 137b are orthogonal to each other. The beam member 137 is fixed using bolts or the like so that the hanging portion 137 b is substantially flush with the side surface of the top plate 30 and the fixing portion 137 a is in surface contact with the back surface side of the top plate 30. Further, an edge member 138 having a substantially “L” cross-sectional shape is fixed to the drooping portion 137 b so as to cover the road surface end portion 7.

  As described above, when the top plate 30 is fixed using the support member 135 and the beam member 137, the installation position of the top plate 30 can be increased by placing the hanging portion 137 a of the beam member 137 on the support portion 136. Adjustment is easy. Therefore, in the case of the configuration as shown in FIG. 13, the position adjustment of the shaft insertion holes 20, 40 and the shaft insertion holes 74, 108 is possible even when the railroad crossing plates 2, 3 are assumed to be bent. Can be carried out easily and accurately, and the crossing connecting shaft 21 can be easily inserted and removed at the other end of the crossing plate 3.

  In the example shown in FIG. 13, an example in which the railroad crossing plate 3 is laid using the beam member 137 instead of the beam member 32 is illustrated, but the present invention is not limited to this, and for example, the railroad crossing plate 2 or the railroad crossing plate In the fixing structure 3, a beam member 137 may be adopted instead of the beam members 11 and 31 arranged on the rail 6 side, and the support member 135 may be fixed to the sleeper 5 according to the mounting position of the beam member 137.

  In the example shown in FIG. 13, the fixing structure that supports the end portions of the crossing plates 2 and 3 using the support member 135 and the beam member 137 is illustrated, but for example, a structure as shown in FIG. 14 is adopted. Also good. More specifically, the support member 140 employed in the example shown in FIG. 14 includes a U-shaped screw shaft 141 that is bent so that the shape when viewed in plan is substantially “U” -shaped, and a cross-sectional shape. A substantially “U” -shaped fixing member 142 is combined. The U-shaped screw shaft 141 is attached to the end of the sleeper 5 on the road surface end 7 side. The U-shaped screw shaft 141 traverses the lower part of the sleeper 5 in the short side direction of the sleeper 5 (the direction in which the rail 6 laid on the upper surface 5t extends), and the tip portion provided with the thread groove faces the front side of the sleeper 5 It is attached to stand up. That is, the U-shaped screw shaft 141 is mounted so as to pass under the sleeper 5 and rise upward.

  On the other hand, the fixing member 142 has a fixing surface 142a and standing surfaces 142b and 142c that rise perpendicular to the fixing surface 142a. The fixing member 142 brings the fixing surface 142a into surface contact with the surface of the sleeper 5 and inserts the tip end portion of the U-shaped screw shaft 141 attached to the sleeper 5 into the two shaft insertion holes 142d and 142d provided in the fixing surface 142a. This is fixed to the sleeper 5 by attaching a nut 143 thereto. When the fixing member 142 is fixed, one of the standing surfaces 142b and 142c (in the example shown in FIG. 14, the standing surface 142b) rises along the front end 5e of the sleeper 5.

  An edge member 138 is attached to the standing surface 142b that rises along the mouth end surface 5e of the sleeper tree 5. As a result, the road surface end 7 is covered by the edge member 138 and is protected.

  In the example shown in FIG. 14, the beam member 137 is fixed to the fixing member 142 in advance. The beam member 137 has a hanging portion 137b fixed to the standing surface 142c such that the fixing portion 137a is parallel to the fixing surface 142a of the fixing member 142. Thereby, the beam member 137 is fixed in a state where the fixing portion 137 a is substantially horizontal to the roadbed G and the sleeper 5 and extends along the rail 6 and the road surface end portion 7.

  As shown in FIG. 14, when the top plate 30 is fixed using the support member 140 and the beam member 137, the top plate 30 is placed on the beam member 137 fixed to the support member 140 side in advance. By fixing, the height adjustment of the installation position of the top plate 30 can be easily performed. Therefore, even in the case of the configuration shown in FIG. 14, the position adjustment of the shaft insertion holes 20 and 40 and the shaft insertion holes 74 and 108 can be easily and accurately performed, and the other end side (rail 6 side) of the railroad crossing plate 3 ), The connecting shaft 21 can be easily inserted and removed.

  In addition, the fixing structure shown in FIG. 14 has a configuration in which the U-shaped screw shaft 141 is passed below the sleeper 5, so that even if a force that lifts from the roadbed G side acts on the top plate 30, It is possible to reliably prevent the face plate 30 and the support member 140 from floating upward.

  Also when the fixing structure as shown in FIG. 15 is adopted, the height position at the time of laying the railroad crossing plates 2 and 3 can be easily implemented as in the fixing structure shown in FIGS. For example, when fixing one end side (road surface end portion 7 side) of the top plate 30 by the fixing structure shown in FIG. 15, the support member 145 and the beam member 137 described above are used in combination. Similar to the support member 135 shown in FIG. 13, the support member 145 includes a horizontal portion 145 a and a standing portion 145 b that rises perpendicular to the horizontal portion 145 a. And in the intermediate part of the horizontal part 145a, it has the support part 145c which stands | starts up substantially parallel with respect to the standing part 145b.

  As shown in FIG. 15, the support member 145 is fixed so that the horizontal portion 145 a comes into surface contact with the surface of the sleeper 5 and the standing portion 145 b rises along the end surface 5 e of the sleeper 5. As in the case of the fixing structure shown in FIG. 14 described above, the beam member 137 is attached to the support portion 145c in advance in the support portion 145c. The beam member 137 extends along the rail 6 and the road surface end portion 7, and is fixed in a posture in which the fixing portion 137 faces upward. With the support member 145 and the beam member 137 thus installed, the top plate 30 is placed and fixed above the beam member 137, whereby one end of the top plate 30 is firmly supported. Therefore, if the fixing structure as shown in FIG. 15 is adopted, the installation height of the top plate 30 can be easily adjusted, and the connecting shaft 21 can be easily inserted and removed at the other end side (rail 6 side) of the top plate 30. Can do.

  In the example shown in FIGS. 13 to 15, the configuration in which one end side of the top plate 30 is supported by the combination of the support members 135, 140, 145 and the beam member 137 is illustrated, but the present invention is limited to this. Instead, for example, as shown in FIG. 16, the support member 150 and the edge member 151 may be combined to support one end of the top plate 30.

  More specifically, in the example shown in FIG. 16, the support member 150 having a substantially “L” cross-sectional shape in which the horizontal portion 150a (base portion) and the standing portion 150b are substantially orthogonal to each other is used. As shown in the drawing, an edge member 151 having a substantially “G” -shaped cross section is attached to the standing portion 150 b of the support member 150. The edge member 151 is a long member having the same length as the railroad crossing plate 3. The edge member 151 includes an edge vertical portion 151a that extends in the vertical direction when installed, and an edge horizontal portion 151b that is substantially perpendicular to the edge vertical portion 151a. The edge horizontal portion 151b is fixed in a cantilever manner with respect to the edge vertical portion 151a. The length from the end (upper end) of the edge vertical portion 151 a to the edge horizontal portion 151 b is approximately the same as the thickness of the top plate 30 or longer than the thickness of the top plate 30 by the thickness of the edge member 152. ing.

  In the fixing structure shown in FIG. 16, similarly to the structure shown in FIG. 15 described above, the standing portion 150 b of the support member 150 is fixed so as to rise along the end face 5 e of the sleeper 5. The vertical portion 151 a of the edge member 151 described above is in surface contact with the standing portion 150, and the horizontal edge portion 151 b is fixed so as to protrude in a direction away from the road surface end portion 7.

  When the fixing structure shown in FIG. 16 is adopted, the top plate 30 is placed above the edge horizontal portion 151b of the support member 150 installed as described above. Then, the edge member 151 having a substantially “L” cross-sectional shape is mounted so as to cover the end of the top plate 30. The top plate 30 and the edge member 151 are fixed to the support member 150 by bolts or the like attached from above.

  Even when the fixing structure as described above is adopted, one end side (the road surface end 7 side) of the top plate 30 can be firmly supported. Therefore, if the fixing structure shown in FIG. 16 is adopted, the position adjustment between the shaft insertion hole 40 of the beam member 31 fixed to the end of the top plate 30 on the rail 6 side and the shaft insertion hole 74 of the support member 50 is performed. It becomes possible to insert the connecting shaft 21 straight. Therefore, if one end of the crossing plate 2 or the crossing plate 3 is supported by a fixing structure as shown in FIG. 16, and the other end side is fixed using the support member 50 or the like and the connecting shafts 19, 21, and 22. The railroad crossing structure 1 can be easily laid.

  Further, the railroad crossing structure 1 is obtained by fixing one end side of the railroad crossing plate 2 or the railroad crossing plate 3 by a fixing structure as shown in FIG. 17 instead of the fixing structure as shown in FIGS. Also good. More specifically, the fixing structure shown in FIG. 17 is configured by combining the support member 150 and the beam member 137 described above. As shown in FIG. 17, the support member 150 is fixed so that the horizontal portion 150a comes into surface contact with the surface of the sleeper 5 and the standing portion 150b rises upward. The beam member 137 is fixed so that the hanging portion 137 is in surface contact with the standing portion 150b and the fixing portion 137 protrudes toward the road surface end portion 7 side.

  A horizontal portion 138 a of the edge member 138 protrudes toward the rail 6 and is fixed to the road surface end 7 so as to be substantially flush with the surface of the road surface end 7. After the end of the top plate 30 is inserted below the horizontal portion 138a, when the top plate 30 is in a horizontal posture, the top plate 30 is placed above the fixed portion 137 of the beam member 137 as shown in FIG. become. In this state, bolts are inserted into the horizontal portion 138a, the top plate 30 and the fixing portion 137a of the beam member 137 from above the edge member 138 and fastened. As a result, the end portion on the one end side (the road surface end portion 7 side) of the top plate 30 is supported by the support structure configured by combining the support member 150 and the beam member 137. Therefore, the position adjustment between the shaft insertion hole 40 of the beam member 31 and the shaft insertion hole 74 of the support member 50 fixed to the end of the top plate 30 on the rail 6 side is also achieved by adopting the fixing structure shown in FIG. The connecting shaft 21 can be inserted straight. Therefore, if the fixing structure shown in FIG. 17 is adopted, the crossing structure 1 can be easily laid.

  Moreover, since the beam member 137 and the support member 150 that constitute the fixing structure shown in FIG. 17 are both configured by combining members having a substantially “L” cross-sectional shape, the structure is extremely simple. Therefore, if a fixing structure as shown in FIG. 17 is adopted, the labor required for laying the level crossing structure 1 and the cost required for laying the level crossing structure 1 can be minimized.

  In each of the above-described embodiments, the edge member 138 or the like covers the end of the top plate 30 or the like, and the configuration capable of preventing the vicinity of the end of the top plate 30 or the like has been exemplified. However, as shown in FIG. It is good also as a structure which fixes separately the cover member 153 comprised with these steel materials. With this configuration, the top plate 30 and the like can be protected. Moreover, if the cover member 153 is mounted so as to straddle the plurality of top plate 30 and the like, the strength of the crossing plate 3 and the like can be further improved.

  In the railroad crossing structure 1 of the above-described embodiment, a steel material having a substantially “L” cross-sectional shape as the beam main bodies 12 and 33 constituting the beam member 11 and the beam member 31 connected to the support member 50 via the connection shafts 19 and 21. However, the present invention is not limited to this. More specifically, the beam members 11 and 31 are replaced with the beam main bodies 12 and 33, respectively. For example, as shown in FIG. ) May be adopted. In the case of such a configuration, as shown in FIG. 18, it becomes possible to cover the beam body on the standing portion 52 of the support member 50, and the railroad crossing plates 2 and 3 extend in the direction in which the rail 6 and the road surface end 7 extend. Thus, it is possible to prevent positional deviation in the intersecting direction (left and right direction in FIG. 18).

  In the crossing structure 1 described above, the crossing plates 2 and 3 are arranged so as to be substantially orthogonal to the rail 6. However, the present invention is not limited to this. For example, the crossing shown in FIG. As in the structure 170, the railroad crossing plates 171 and 172 may be installed so as to be inclined at an arbitrary angle θ with respect to the rail 6.

  More specifically, the level crossing plates 171 and 172 constituting the level crossing structure 170 have the same configuration as the level crossing plates 2 and 3 except for the shapes of the top plate 175 and 176 (top surface part). . That is, as shown in FIG. 19 and FIG. 20, the railroad crossing plate 171 is formed by arranging three top plates 175 having a substantially parallelogram in plan view and connected by the beam member 11 fixed to the back side thereof. The beam members 11 and 11 are fixed so that part of the beam main bodies 12 and 12 protrude from both ends of the crossing plate 171, respectively.

  As for the crossing plate 172, as shown in FIGS. 19 and 21, three top plates 176 having a substantially parallelogram in plan view are arranged and connected by beam members 31 and 32 fixed to the back side thereof. It is structured. The beam members 31 and 32 are fixed so that part of the beam main bodies 33 and 35 protrude from both end portions of the railroad crossing plate 172, respectively.

  Also in the level crossing structure 170, the level crossing plates 171 and 172 are fixed using the support members 50 and 100 employed in the level crossing structure 1 described above. That is, as shown in FIG. 19, the support member 50 supports the rail 6 at a position where the L-shaped fixing plate 13 of the beam member 11 fixed to the crossing plate 171 arrives when the crossing structure 170 is laid. 50 is fixed. Further, the support member 100 is fixed at a position where the rectangular fixing plates 34 of the beam members 31 and 32 arrive when the railroad crossing plate 172 is laid.

  When the support members 50 and 10 are attached as described above, the railroad crossing plates 171 and 172 are fitted from above in the inside and outside the gauge. Then, alignment of the shaft insertion holes 20 and 40 of the beam member 11 and the beam members 31 and 32 fixed to each crossing plate 172 and the shaft insertion holes 74 and 108 provided on the fixing members 50 and 100 side is performed. The connecting shafts 19, 21, 22 are inserted over these. Installation of the railroad crossing structure 170 is completed by attaching nuts to the connecting shafts 19, 21, and 22.

However, the present invention is not limited to this. For example, a substantially “U” -shaped beam member at the end of the top plate 10 or the top plate 30 as in the crossing structures 180 and 190 shown in FIGS. 181, 192 (end mounting member) and a substantially “L” -shaped beam member 191 (end mounting member) may be mounted.

  More specifically, the railroad crossing structure 180 shown in FIG. 23 is substantially the same as the railroad crossing structure 1 shown in FIG. 3, but three roofs arranged between the rails 6 and 6 (inside the rail). A beam member 181 is mounted on both end portions 10b, 10b in the longitudinal direction of the face plate 10. Further, in the railroad crossing structure 180, beam members 181 are also mounted on the longitudinal ends 30b, 30b of the three top plates 30 arranged outside the rails 6, 6 (outside the gauge).

  As shown in FIG. 24A, the beam member 181 is made of a steel material having a substantially “U” -shaped cross section. The length of the beam member 181 is adjusted in consideration of the number and width of the top plates 10 and 30 constituting the railroad crossing structure 180 (the length of the side extending along the rail 6 when laid on the road bed). That is, the length of the beam member 181 is substantially the same as the length obtained by multiplying the width and the number of the top plates 10 and 30. Since the railroad crossing structure 180 of this embodiment is configured by arranging the three top plates 10 and the top plate 30, the length of the beam member 181 is about three times the width of the top plates 10, 30. Has been.

  The beam member 181 includes a top surface 181a that is horizontal when installed, a bottom surface 181b that faces the top surface 181a and that is substantially parallel to the roadbed, and a vertical surface 181c that is substantially perpendicular to both the top surface 181a and the bottom surface 181b. And a portion facing the vertical surface 181c is open.

  Two substantially rectangular notches 181d are provided on the bottom surface 181b. The notch 181d interferes with the L-shaped fixing plate 13 and the rectangular fixing plate 34 that are fixed to the back surface side of the top plate 10, 30 when the beam member 181 is attached to the top plate 10, 30. This is provided in consideration of the mounting position of the L-shaped fixing plate 13 and the rectangular fixing plate 34. The top surface 181a and the bottom surface 181b are provided with a plurality of through holes 181e at predetermined intervals in the longitudinal direction of the beam member 181. The through hole 181e provided in the bottom surface 181b is located vertically below the through hole 181e provided in the top surface 181a. A nut 181f is fixed to the outside of the bottom surface 181b (lower side in the installed state) by welding.

  As shown in FIG. 23 and FIG. 24 (b), the beam member 181 includes an end portion 10 b of the top plate 10 and a fixing portion 15 of the beam member 11 attached to the back surface side of the top plate 10. The vertical surface 181c is mounted so as to be in surface contact with or opposed to the end surface 10c of the top plate 10. Further, as shown in FIG. 23, with the beam member 181 attached in this manner, the bolt 182 extends from the top surface 181a side to the bottom surface 181b side of the beam member 181 so as to penetrate between the through holes 181e and 181e. Is inserted. The bolt 182 is inserted so as to penetrate the top plate 10 and the fixing portion 15 of the beam member 11 sandwiched between the top surface 181a and the bottom surface 181b of the beam member 181, and is fixed to the bottom surface 181b side of the beam member 181. The nut 181f is attached.

  Further, as shown in FIG. 24B, in the railroad crossing structure 180 of the present embodiment, the three top plates 10 are attached to one beam member 181. Therefore, when the three top plates 10 are attached to the beam members 181 as described above, the top plates 10 are connected by the beam members 181.

  As shown in FIG. 23, the beam member 181 is also attached to the top plate 30 installed outside the gauge in the same manner as the top plate 10 is mounted. That is, the beam member 181 sandwiches the end 30b of the top plate 30 and the beam member 33 attached to the back side of the top plate 30 and the fixing portions 36 and 37 of the beam member 35 between the top surface 181a and the bottom surface 181b. The vertical surface 181c is mounted so as to contact or face the end surface 30c of the top plate 30. In this state, the bolt 182 is attached from the top surface 181a side to the bottom surface 181b side of the beam member 181 and is attached to the nut 181f. Thereby, the beam member 181 is integrated with the top plate 30 and the beam members 33 and 35.

  As shown in FIG. 23, the railroad crossing structure 180 is constructed by laying the top panels 10 and 30 to which the beam members 31, 32 and the beam member 181 are attached on the roadbed in the same manner as the railroad crossing structure 1 shown in FIG. It is constituted by doing.

  As described above, the railroad crossing structure 180 according to the present embodiment is mounted so as to cover the end portions 10b and 30b of the top plate 10 and 30 and the end surfaces 10c and 30c with the long beam member 181 and support members. 50 and 100 are integrally attached. Therefore, the crossing structure 180 can firmly fix the end portions 10b, 30b of the top plate 10, 30 or the vicinity thereof.

  Further, in the railroad crossing structure 180 of the present embodiment, a plurality of (three) top plates 10, 30 arranged side by side in the direction in which the rail 6 extends are attached to and integrated with one beam member 181. Therefore, the strength of the crossing structure 180 as a whole is high.

  Furthermore, in the railroad crossing structure 180 of the present embodiment, it is assumed that there is a high possibility of wear or damage like the vicinity of the end portions 10b, 30b of the top plate 10, 30 or the end surfaces 10c, 30c of the top plate 10, 30. The portion is covered and protected by the beam member 181. Therefore, the railroad crossing structure 180 can minimize the frequency of replacement and maintenance of the top plate 10, 30.

  The crossing structure 190 shown in FIG. 25 is substantially the same in configuration as the modified example of the crossing structure 1 shown in FIG. However, the railroad crossing structure 190 extends toward the end 30b side of the top plate 30 along the back surface of the top plate 30 to the beam member 31 fixed to the back surface of the top plate 30 constituting the crossing plate 3. The configuration differs in that the extension portion 31a is provided and the beam members 191 and 192 are attached to the top plate 10 and 30.

  More specifically, as shown in FIG. 18, the railroad crossing structure 190 includes beam members 191 having a substantially “L” cross-sectional shape at both longitudinal ends 10 b and 10 b of the top plate 10 disposed in the rail. It is supposed to be installed. Further, the railroad crossing structure 190 is configured such that a beam member 192 having a substantially “U” -shaped cross section is attached to the end portion 30b of the top plate 30 disposed outside the gauge.

  As shown in FIG. 25, the beam member 191 is attached to the top plate 10 so as to cover the end portion 10b side portion and the end surface 10c. The beam member 191 inserts a bolt 193 so as to penetrate the top plate 10 and the beam member 11 attached to the back surface side from above, and fastens this to a nut 195 provided on the back surface side of the beam member 11. It is fixed by.

  In the same manner as the beam member 181 employed in the crossing structure 180 described above, the beam member 191 covers substantially the entire end portion 10b of each top plate 10 in consideration of the number and width of the top plate 10 constituting the crossing structure 190. The length is adjusted to cover.

  On the other hand, the beam member 192 attached to the top plate 30 laid outside the gauge is substantially “U” shaped as shown in FIG. The beam member 192 has a top surface 192a, a bottom surface 192b parallel to the top surface 192a, and a vertical surface 192c perpendicular to the top surface 192a and the bottom surface 192b, and a portion facing the vertical surface 192c is a top surface plate 30 or a beam. The extension 31a of the main body 31 is opened so that it can be inserted.

  A through hole 192d into which a bolt 193 can be inserted is provided in the top surface 192a and the bottom surface 192b of the beam member 192, as will be described later. A nut 192e capable of fastening a bolt 193 inserted through the through hole 192d is welded to the bottom surface 192b.

  In the same manner as the beam member 181 employed in the above-described crossing structure 180, the beam member 192 sandwiches the end portion 30b of the top plate 30 and the extended portion 31a of the beam member 31 between the top surface 192a and the bottom surface 192b, and the vertical surface 192c. Is mounted so as to be in surface contact with or opposed to the end surface 30c of the top plate 30. The beam member 192 is inserted into the through hole 192d from above the top surface 192a with the bolt 193 passing through the top surface plate 30 and the extending portion 31a of the beam member 31 attached to the back surface side. It is fixed by fastening a nut 192e provided on the back side of the beam member 192.

  As described above, also in the crossing structure 190, the end portions 10b and 30b of the top plates 10 and 30 and the end surfaces 10c and 30c are covered by the long beam members 191 and the beam members 192, similarly to the crossing structure 180 described above. Since these are attached integrally to the supporting members 50 and 100, the top plate 10 and 30 can be firmly fixed.

  Further, the railroad crossing structure 190 of the present embodiment has a plurality of (three in the present embodiment) top plates 10 and 30 attached to and integrated with one beam member 191 and 192. As strength is high. Further, the railroad crossing structure 190 has a configuration in which the top surfaces 10 and 30 are in the vicinity of the end portions 10b and 30b and the end surfaces 10c and 30c are covered with the beam members 191 and 192. The damage and wear of 30c can be minimized.

  The crossing structures 180 and 190 described above are merely examples of a modification of the crossing structures 1 and 170 described above. For example, a crossing structure shown in FIG. 23 arranged outside the gauge like a crossing structure 200 shown in FIG. The support member 100 employed in 180 may be configured to be fixed to the sleeper 5. Hereinafter, the crossing structure 200 will be described.

  The crossing structure 200 is largely the same as the above-described crossing structure 180, but the fixing structure of the support member 100 disposed outside the gauge is greatly different. More specifically, in the railroad crossing structure 200, the lower support member 201 is disposed at the longitudinal end of the sleeper 5 placed on the road bed, and the support member 100 is fixed to the sleeper 5 using this. Has been.

  The lower support member 201 is a member having a lower base portion 201a and an end surface contact portion 201b substantially perpendicular to the lower base portion 201a and a substantially “L” -shaped cross section. The lower base portion 201a has a through hole 201c into which a bolt 202 described later can be inserted. Further, a nut 201d capable of fastening the bolt 202 inserted through the through hole 201c is fixed by welding to the back side of the lower base portion 201a, that is, the portion facing the roadbed when arranged as shown in FIG.

  The lower support member 201 is disposed in a state where the lower base portion 201 a is sandwiched between the road bed and the bottom surface of the sleeper 5 and the end surface contact portion 201 b is in contact with the mouth of the sleeper 5. Therefore, the lower support member 201 is not displaced or detached from the sleeper 5 unless a very large impact is applied.

  In the state where the lower support member 201 is arranged as described above, the through hole 201c provided in the lower base portion 201a exists at a position communicating with the sleeper 5 described later and through holes 5a and 101a of the support member 100.

  As shown in FIG. 26, the support member 100 is arranged so that the base portion 101 is positioned in the vicinity of the longitudinal direction end portion on the top surface side of the sleeper 5. The base portion 101 is provided with a through hole 101a, and the sleeper 5 is provided with a through hole 5a at a position where the support member 100 communicates with the through hole 101a.

  The through hole 101a of the support member 100 and the through hole 5a of the sleeper 5 communicate with the through hole 201c of the lower support member 201 described above. Bolts 202 are inserted into the through holes 101a, 5a, and 201c from above. The bolt 202 is screwed with a nut 201 d welded to the lower support member 201. Thereby, the support member 100 is fixed to the sleeper 5.

  As described above, in the crossing structure 200, the sleeper 5 is sandwiched between the horizontal portion 101 and the lower base portion 201a of the support member 100, and the bolt 202 inserted through the horizontal portion 101, the sleeper 5 and the lower base portion 201 is used. The support member 100 and the lower support member 201 are fixed to the sleeper 5. Therefore, if it is set as the crossing structure 200, the top plate 30 currently laid using the supporting member 100 can be firmly fixed on the roadbed.

  The above-mentioned crossing structure 200 can be made strong by fixing it to the sleeper 5 using the lower support member 201 as described above for all the support members 100, but some of the support members Only 100 may be fixed to the sleeper 5 using the lower support member 201. In the case of such a configuration, in order to make the railroad crossing structure 200 a strong configuration, among all the support members 100 used for the construction of the railroad crossing structure 200, those that are positioned at least at both ends in the extending direction of the rails 6 and 6 It is desirable to adopt a configuration in which the lower support member 201 is used to fix to the sleeper tree 5.

  Further, the railroad crossing structure 200 may be configured such that a cushioning material such as a rubber plate is interposed between the support member 100 or the lower support member 201 and the sleeper 5. Such a configuration can further prevent the surface of the sleeper 5 from being worn, and is even more preferable.

  Although the above-described crossing structure 200 has been described as a modified example of the crossing structure 1, the present invention is not limited to this, and the crossing structure 170 and the like also support the lower support member 100 in the same manner as the crossing structure 200. It is good also as fixing to pillow 5 in combination with 201. In this case, the support member 100 may be attached to all the sleepers 5 using the lower support member 201 as in the crossing structure 200 described above. For example, as shown in FIG. The support member 100 may be attached to the sleeper 5 located on the side using the lower support member 201, and the support member 100 may be fixed to the support member 100 existing in the middle portion in the same manner as the crossing structures 1 and 170. .

  The crossing structures 180, 190, 200 described above are beam members 181, 191, so as to cover the end surfaces 10c, 30c and the end portions 10b, 30b, which are parallel to the rails 6, 6 of the top plate 10, 30, respectively. 192 or the like, but the end surfaces and end portions extending in the longitudinal direction of the top plates 10 and 30, that is, the end surfaces and end portions extending in the direction intersecting with the rails 6 and 6, are attached to the beam members 181 and 192. As described above, a steel material having a substantially “U” -shaped cross section may be mounted, or a steel material having a substantially “L” -shaped cross section may be mounted as in the beam member 191. According to such a configuration, the strength of the railroad crossing structures 180, 190, 200, etc. can be further improved, which can contribute to the prevention of breakage of the railroad crossing plates 10, 30 and the improvement of the strength.
