  Conventionally, a trough in which a power cable, a signal cable and the like are disposed may be installed inside along a track such as a railway. For example, a trough support can be erected on the ground, and a trough receiver can be fixed on the trough support to form a trough bridge, and the trough can be installed on the trough bridge.

  As a method of constructing such a trough bridge, for example, a method using a pair of support piles, a holding rod having a pair of ring-shaped support pile rings, and a cable trough fixture has been proposed (patented) Literature 1).

  In Patent Document 1, first, a pair of support piles are driven into a cable trough bridge construction site by setting a distance between the support piles. Next, from the upper end side of the driven support pile, a holding rod having a pair of ring-shaped support pile fitting rings at both ends is inserted between the support piles by inserting the support pile fitting ring into the support pile. In addition, a cable trough fixture, which is adjustable in the width direction of the cable trough bridge, is mounted on the holding rod. A trough bridge is constructed by the above.

  Moreover, it is possible to install so that both sides of a stand may not be made to project from a trough bridge, and the variable-width trough bridge which was excellent in workability | operativity is proposed (patent document 2).

  In Patent Document 2, a plurality of flat plate-like pedestals mounted on columns erected on the ground, and a support frame having an angular cross-sectional shape attached to the pedestal and supporting the trough are used. Each support frame holds the horizontal portion of the support frame in a state in which the movement of the support frame in the width direction is restricted, and is held by a pair of sandwiching plates that extend and overlap in the central direction of the pedestal than the horizontal portion. Be done. The pair of sandwiching plates is fixed to the pedestal by the bolts and nuts inserted into the bolt holes of the sandwiching plate and the pedestal. One bolt hole of the clamp plate and the pedestal is a long hole along the width direction.

  FIG. 15 is a view showing an example of a conventional trough line 100 using, for example, such a trough bridge. The trough line 100 mainly includes a support member 105, a trough receiver 107, a trough 103, and the like. A support member 105 is installed on the ground 101.

  FIG. 2 is a perspective view showing the trough support pile 1. The trough support pile 1 which is a trough support member is comprised from the support | pillar 3 and the trough support part 5. FIG. The trough support 5 includes a bottom 7 and side walls 9 provided on both sides of the bottom 7. In the illustrated example, the trough supporting portion 5 is disposed by opposing a pair of L-shaped angle members, and the L-shaped angle members are connected to each other by a connecting member.

  The vicinity of the tip end of the support 3 is fixed to the outer surface of the side wall 9 of the trough support 5 by a weld 11. The upper end of the support 3 projects above the upper edge of the side wall 9. The support 3 is, for example, a member having an L-shaped cross section.

  In addition, although the cross-sectional shape of the support | pillar 3 may be arbitrary shapes, it is desirable that it is not a cylindrical closed cross-sectional shape. When the column 3 has a cylindrical shape, when the column 3 is driven into the ground, the inside of the column 3 is clogged with stones and soil, and the resistance becomes large, so that it is difficult to be struck. In addition, in order to make it easy to drive in the support | pillar 3, the lower end part of the support | pillar 3 is formed in acute angle.

  The trough main body 13 is installed on the trough support 5. FIG. 3 is a perspective view of the trough body 13 and the trough lid 29. FIG. The trough main body 13 and the trough lid 29 are made of, for example, resin, and are molded by press molding or injection molding. The trough main body 13 includes a bottom plate 15 and a pair of side plates 17 formed on both sides of the bottom plate 15 and has an opening 19 at the top.

  A male fitting portion 21 and a female fitting portion 23 are provided at both ends of the trough main body 13 in the longitudinal direction. The female fitting portion 23 has a recessed groove on the inner surface side of the trough main body 13, and the male fitting portion 21 has a protrusion corresponding to the recessed groove on the outer surface side of the trough main body 13. Therefore, by fitting the male fitting portion 21 of one trough body 13 and the female fitting portion 23 of another adjacent trough body 13 to each other, the trough bodies 13 can be connected to each other. .

  Here, a portion between the male fitting portion 21 and the female fitting portion 23 is referred to as a body portion 25. That is, the trough main body 13 has a body 25 and a male fitting 21 and a female fitting 23 which are provided at the front and rear ends of the body 25 and can be fitted and connected to each other. In the body portion 25, lateral ribs 27 protruding outward from the side plate 17 are provided on both sides of the bottom plate 15. The transverse rib 27 is formed in the longitudinal direction of the body 25.

  The trough lid 29 closes the opening 19 at the top of the trough main body 13. A groove 31 is provided on the top surface of the trough lid 29 in the width direction. Further, a rib 33 is provided at a portion of the trough main body 13 corresponding to the groove 31.

  FIG. 4 is a cross-sectional view in the vicinity of the metal band 45 of the fixing structure 10 of the trough main body and the trough support member. The metal band 45 is disposed in the groove 31. The trough lid 29 is fixed to the trough body 13 by a metal band 45.

  The metal band 45 is made of a metal band-shaped member having a spring property. The metal band 45 is formed by bending a plate-like metal plate and has a substantially U-shape. The end of each end of the metal band 45 is bent to form a locking portion.

  After the trough body 13 is fixed to the trough support 5, the trough lid 29 can be placed on the opening 19 of the trough body 13 and fixed by the metal band 45. The metal band 45 is attached to the groove 31 of the trough lid 29, and the locking portions at both ends of the metal band 45 are fixed to the rib 33 provided on the upper outside of the side plate 17 of the trough main body 13. Thus, the trough lid 29 can be fixed to the trough body 13.

  The height of the side wall 9 of the trough support 5 is lower than the height from the bottom of the trough main body 13 to the rib 33. Therefore, when the metal band 45 is fixed, the metal band 45 and the side wall 9 of the trough support 5 do not interfere with each other.

The trough main body 13 is fixed to the trough support 5 by a fixing bracket 35. FIG. 5 is a perspective view of the fixing bracket 35. The fixing bracket 35 is formed of a plate-like member having a spring property, and is configured by folding back the plate-like member. The respective bent end portions of the fixing bracket 35 are formed with a pressing portion 39 and a fixing portion 41, and the pressing portion 39 and the fixing portion 41 oppose each other with the insertion portion 37 interposed therebetween. That is, the fixing bracket 35 is a plate-like member having a substantially L-shaped spring property formed by bending so as to face with each other while a predetermined distance away across the insertion portion 37, each tip of the plate-like member The pressing portion 39 and the fixing portion 41 are formed. The pressing portion 39 side is shorter than the fixing portion 41 side, and the tip end position of the pressing portion 39 is located above the tip end position of the fixing portion 41 (the folded portion side of the plate-like member).

  The height of the side wall portion 9 of the trough support portion 5 is higher than the height from the bottom surface of the trough main body 13 to the lateral rib 27, and the height of the fixing bracket 35 is aligned with the height of the side wall portion 9. It is formed. Therefore, when fixing the trough main body 13 to the trough supporting portion 5 with the fixing bracket 35, the fixing bracket 35 can be stably supported by the side wall portion 9 of the trough supporting portion 5.

The tip end portions of the pressing portion 39 and the fixing portion 41 are bent in the same direction. That is, the fixing portion 41 is bent toward the insertion portion 37, and the tip of the pressing portion 39 is disposed on the opposite side of the fixing portion 41 so as to face each other with the tip of the fixing portion 41 with the insertion portion 37 interposed therebetween. Be done. Moreover, the hole 43 is provided in a part of plate-shaped member by the side of the fixing portion 41. The hole 43 is used when removing the fixing bracket 35, and a tip of a driver or the like can be inserted.

  Fig.6 (a) is sectional drawing of the fixing metal fitting 35 vicinity of the fixing structure 10 of a trough main body and a trough support member, FIG.6 (b) is the A section enlarged view of Fig.6 (a). In the following description, illustration of cables and the like inside the trough main body 13 is omitted.

  With the trough main body 13 disposed in the trough supporting portion 5, the side wall portion 9 of the trough supporting portion 5 is inserted into the insertion portion 37 (see FIG. 5) of the fixing bracket 35 from the top of the trough supporting portion 5. In this state, by pushing the fixing bracket 35, the lateral rib 27 of the trough main body 13 is pressed from above by the tip of the pressing portion 39, and the tip of the fixing portion 41 is locked to the bottom 7 side of the trough support 5. As a result, the trough main body 13 can be fixed to the trough support 5 by the fixing bracket 35.

  Further, since the fixing bracket 35 has springiness, the pressing portion 39 and the fixing portion 41 strongly sandwich the trough supporting portion 5 and the trough main body 13. For this reason, when fixing the trough main body 13 to the trough support 5, the trough main body 13 can be firmly fixed to the side wall 9 of the trough support 5.

  Next, a method (step) of fixing the trough main body 13 to the trough support pile 1 will be described. First, as shown in FIG. 7A, the trough support pile 1 is installed on the ground 47. At this time, the head of the column 3 is driven in until the back surface of the trough support 5 comes in contact with the ground surface, and the trough support pile 1 is driven (arrow B in the figure). At this time, since the head of the column 3 protrudes upward relative to the trough support 5, the trough support 5 is not damaged at the time of placing.

  Next, as shown in FIG. 7 (b), the body 25 of the trough main body 13 is placed on the trough support 5. In addition, on the trough support part 5, a part of the trunk | drum 25 should just be located. That is, the male fitting portion 21 and a part of the female fitting portion 23 may be placed on the trough supporting portion 5.

  Next, as shown in FIG. 8, the trough main body 13 is fixed to the trough supporting portion 5 by the fixing bracket 35. That is, the trough main body 13 can be fixed to the trough support pile 1 by fixing the trough supporting portion 5 and the lateral rib 27 of the trough main body 13 with the fixing bracket 35. Under the present circumstances, if it is a formation position of the horizontal rib 27 of the trough main body 13, the fixing bracket 35 can be fixed in any position. For this reason, the position of the trough support pile 1 may be shifted somewhat. Moreover, it is also possible to shift and fix the position of the trough main body 13 a little.

  Although the lateral ribs are not formed at the positions where the male fitting portion 21 and the female fitting portion 23 of the trough main body 13 are formed, the longitudinal ribs 28 formed to increase the load resistance of the trough to the trough body portion. Since it is formed in all the positions except the position which interferes with it, the freedom degree of installation of the fixing bracket 35 at the time of fixing the trough main body 13 to the trough support part 5 will be very high.

  The length of the trough supporting portion 5 is shorter than the length of the trough main body 13. Thus, the trough body 13 is supported by the trough support 5 only in part. The trough main body 13 protruding from the trough support portion 5 is installed so as to substantially contact the ground 47.

  To place it so as to make a substantial contact means that a portion of the bottom plate 15 of the trough body 13 contacts the ground or ballast but not a portion, but this is originally on the ground where the trough is to be installed, This is because there are some irregularities, so-called uneven land.

  Finally, a cable or the like is accommodated in the trough main body 13, and the trough lid 29 is placed on the trough main body 13. Furthermore, the metal band 45 is disposed from above the trough lid 29 to fix the trough lid 29 to the trough body 13. Thus, the construction of the fixing structure 10 for the trough body and the trough support member is completed.

  Further, the trough main body 13 may be additionally provided to the fixing structure 10 of the trough main body and the trough support member. In this case, as shown in FIG. 9A, first, the fixing structure 10 of the trough main body and the trough supporting member is constructed.

  As described above, the fixing structure 10 of the trough body and the trough support member drives the first trough support pile 1 by driving the support 3 until the back surface of the trough support portion 5 contacts or substantially contacts the ground surface. The first trough main body 13 is placed on the trough supporting portion 5, and the first support main body 13 is fixed to the lateral rib 27 of the first trough main body 13 by the fixing bracket 35. It is constructed by fixing the main body 13 to the first trough support pile 1.

  Next, the second trough support pile 1 is driven away from the first trough support pile 1 by a predetermined distance. For example, a pair of trough support piles 1 are installed apart from each other by a length substantially corresponding to the length of the trough main body 13.

  From this state, as shown in FIG. 9B, the body 25 of the second trough main body 13 is placed on the trough support 5 of the second trough support pile 1, and the first trough main body 13 and the first trough main body 13 are The male fitting portion 21 and the female fitting portion 23 of each of the two trough main bodies 13 are mutually connected. Furthermore, by fixing the trough support portion 5 of the second trough support pile 1 and the lateral rib 27 of the second trough main body 13 with the fixing bracket 35, the second trough main body 13 is formed as the second trough support pile 1 Fix to

  By the above, it is possible to fix the plurality of connected trough main bodies 13 to the plurality of trough support piles 1 arranged to be separated from each other by a predetermined distance. That is, a pair of trough main bodies 13 are connected, and the fixing structure 10a of the trough main body and the trough support member each supported by the trough support pile 1 can be constructed. At this time, as described above, since the trough support portion 5 is shorter than the trough main body 13, the trough support portion 5 supports only a part of the trough main body 13.

  Furthermore, the trough main body 13 may be provided side by side with respect to the fixing structure 10a of the trough main body and the trough support member. First, as shown in FIG. 10A, the trough support pile 1 is driven at a predetermined distance from the fixing structure 10a of the trough main body and the trough support member.

  From this state, as shown in FIG. 10 (b), the body portion 25 of the trough main body 13 is placed on the trough support portion 5 of the trough support pile 1, and each male fitting portion of the adjacent trough main body 13 21 and the female fitting portion 23 are connected. Furthermore, the trough main body 13 is fixed to the trough support pile 1 by fixing the trough support portion 5 of the trough support pile 1 and the lateral rib 27 of the trough main body 13 with the fixing bracket 35.

  Thus, the trough line is formed by repeating the installation of the plurality of trough support piles 1, the connection of the plurality of trough bodies 13, and the fixing of the respective trough bodies 13 to the plurality of trough support piles 1 a plurality of times. 20 can be laid.

  In addition, it is not necessary to arrange one trough main body 13 on one trough support pile 1. For example, one trough main body 13 may be supported by a plurality of trough support piles 1. Further, as shown in FIG. 11, the trough support pile 1 may be installed in the vicinity of the connection portion of the trough main body 13. In this case, if the both sides of the trough supporting portion 5 are respectively positioned at the trunk portion 25 (the forming position of the lateral rib 27) of the trough main body 13, the trough main body 13 is fixed to the trough supporting pile 1 Can.

  As described above, according to the present embodiment, the plurality of trough bodies 13 are fixed to one another on the trough support portion 5 of the trough support pile 1 installed at a predetermined interval, while being mutually connected to each other. There is no need to build a trough bridge over the entire length of the range. Therefore, the work is easy and the amount of material used can be small.

  In addition, since the trough support portion 5 is driven into contact with the ground 47, the trough main body 13 can be installed and fixed at an arbitrary position such as, for example, on a ballast. At this time, work such as digging up the ballast is unnecessary. For this reason, work is easy.

  Moreover, since the support | pillar 3 of the trough support pile 1 uses not an reinforcement pile but an equilateral angle steel (angle steel) of a predetermined dimension, the support | pillar 3 does not bend by the repulsive force from a ballast at the time of pile driving.

  In addition, since the side wall 9 of the trough support 5 is fixed by the welding portion 11 in the vicinity of the tip end of the support 3, the trough support 5 can be installed at the same time as the support 3 is inserted. Moreover, since the support | pillar 3 and the trough support part 5 are comprised integrally, a number of parts can be decreased.

  Also, by placing the trough lid 29 in the opening 19 of the trough body 13 and fixing the trough lid 29 and the trough body 13 with the substantially U-shaped metal band 45, the trough lid 29 can be reliably secured. It can be fixed to the trough body 13. Moreover, the metal band 45 and the trough support pile 1 do not interfere at the time of installation operation of the trough lid | cover 29. As shown in FIG.

  Further, the fixing bracket 35 is formed of a plate-like member having a spring property, and the pressing portion 39 and the fixing portion 41 are respectively formed via the insertion portion 37. Therefore, only by fitting the fixing bracket 35 into the side wall 9 from above the trough support 5, the lateral rib 27 is pressed from above by the pressing section 39, and the fixing bracket 41 fixes the bracket to the trough support 5. 35 can be fixed. For this reason, there is no need to fasten bolts, nuts, etc., and the workability is good.

  Moreover, when the trough main bodies 13 are fitted by the male fitting portion 21 and the female fitting portion 23 and supported by the trough support piles 1 respectively, the trough main bodies 13 connected to each other can be supported.

  Further, at this time, since the body portion 25 of the trough main body 13 has a predetermined length unlike the male fitting portion 21 and the female fitting portion 23 at the front and rear ends of the trough main body 13, the body portion is It is possible to fix the trough body 13 to the trough support 5 of the trough support pile 1 also in most of the 25 longitudinal positions. For this reason, adjustment of the position of the trough main body 13 with respect to the longitudinal direction of the trough main body 13 is easy.

  For example, in order to fix each trough main body 13, it is desirable that the installation interval of the trough support piles 1 basically be a constant distance corresponding to the length of the trough main body 13. However, in order to lay the trough main body 13 on the ballast, the pillars 3 of the trough support pile 1 may be repelled by the ballast at the time of laying and a slight positional deviation may occur. According to the present embodiment, the trough main body 13 can be fixed to the trough support 5 even if the laying position of the trough support pile 1 has some variation.

  Thus, if the transverse rib 27 of the trunk portion 25 is located in the trough support portion 5 of the trough support pile 1, the trough body 13 can be fixed to the trough support pile 1 at any position. There is a high degree of freedom in the positions of 13 and the trough support pile 1. Therefore, it is possible to obtain a simple and efficient method of laying the trough line 20 without using the trough bridge and not worrying about the placement position accuracy of the trough support pile 1.

  Next, a second embodiment of the trough support pile will be described. FIG. 12 is a perspective view showing the trough support pile 1a. In addition, in the following description, about the structure which show | plays the function same as the trough support pile 1, the code | symbol same as FIG. 2 etc. is attached | subjected, and the overlapping description is abbreviate | omitted.

  Although the trough support pile 1a is the structure substantially the same as the trough support pile 1, the forms of the trough support part 5 differ. The trough support portion 5 of the trough support pile 1a is formed in a substantially U-shape by bending a single plate-like member. That is, the bottom 7 and the side wall 9 are integrally formed.

  Thus, if the bottom 7 and the side wall 9 are provided, the configuration of the trough support 5 makes L-shaped angle members face each other like the trough support pile 1 and is connected by the connecting member by welding or the like. As in the case of the trough support pile 1a, an integral plate may be bent and formed.

  According to the second embodiment, the same effect as that of the first embodiment can be obtained. That is, regardless of the form of the trough support portion 5, the trough support pile 1 a can be applied similarly to the trough support pile 1.

  Next, a third embodiment of the trough support pile will be described. FIG. 13 is an exploded perspective view showing the trough support pile 1b. Although the trough support pile 1b is the structure substantially the same as the trough support pile 1a, it differs in that the trough support part 5 and the support | pillar 3 are separate bodies.

  A retaining portion 49 is provided on the head (upper end) of the column 3 of the trough support pile 1b. The retaining portion 49 is, for example, a plate-like member. The trough support portion 5 of the trough support pile 1b is disposed with the pair of L-shaped angle members facing each other, and is connected by another plate member at a predetermined interval. Therefore, a gap is formed in the bottom 7 of the trough support 5 between the L-shaped angle member and the connecting member.

  The retaining portion 49 is smaller in size than the distance between the side wall portions 9 of the trough supporting portion 5. Further, the retaining portion 49 is larger than the gap of the bottom portion 7 formed between the L-shaped angle member and the connecting member described above. The size of the support 3 is smaller than the gap of the bottom 7 formed between the L-shaped angle member and the connecting member described above.

  Fig.14 (a) and FIG.14 (b) are figures which show the process of installing the trough support pile 1b. First, the trough support 5 is placed on the ground 47. Next, the support 3 is disposed in the gap of the bottom 7 described above and driven into the ground 47 (arrow C in the figure).

  As described above, since the size of the support 3 is smaller than the gap size, the support 3 does not interfere with the bottom 7 of the trough support 5. On the other hand, since the retaining portion 49 is larger than the gap size, as shown in FIG. 14B, the retaining portion 49 comes in contact with the bottom portion 7 when the column 3 is completely knocked in. Therefore, the trough supporting portion 5 can be fixed by the retaining portion 49.

  According to the third embodiment, the same effect as that of the first embodiment can be obtained. In addition, since the support 3 and the trough support 5 are separate bodies, for example, in order to install the large trough main body 13, even when the trough support pile is enlarged, it is integrated by dividing into individual members. Compared to the above, the weight of the column 3 alone and the weight of the trough support 5 alone can be reduced. Therefore, it is easy to handle.

  Although the embodiments of the present invention have been described above with reference to the attached drawings, the technical scope of the present invention is not influenced by the above-described embodiments. It is apparent that those skilled in the art can conceive of various changes or modifications within the scope of the technical idea described in the claims, and they are naturally also within the technical scope of the present invention. It is understood that it belongs.
