Description

  The present invention relates to a wire rope tying tool for binding the ends of a wire rope, and a method for binding the ends of the wire rope using the wire rope tying tool.

  Patent Document 1 describes a connector for slidably connecting two wire ropes. This connector is constituted by a combination of an inner member having a C-shaped cross section and an outer member having a C-shaped cross section into which the inner member is inserted. Wire ropes to be joined by a joining tool (a pillar fall prevention wire rope and a pillar rotation prevention wire rope) are installed by penetrating the pillars constituting the soundproof wall.

Since there is a gap in the longitudinal direction of both the inner member and the outer member constituting the joint described in Patent Document 1, a strong impact is applied to the soundproof wall or the joint, or a strong force is applied to the wire rope. This gap may open outward. There is a possibility that the wire rope may be disconnected (connected).
JP 2006-328766 A

  An object of the present invention is to provide a wire rope tying tool having a structure capable of keeping the wire rope bound (connected) even when a strong force is applied to the wire rope.

  The present invention provides a method for binding ends of wire ropes using the wire rope binding tool.

  The wire rope binding tool according to the present invention is for binding (connecting) the ends of the wire rope. The ends of the wire rope may be the ends of two or more wire ropes, or may be the ends of at least one wire rope.

  The wire rope tying device according to the present invention includes two inner halves and one cylindrical body. In each of the two inner halves, at least two wire rope grooves are formed parallel to each other. An inner body obtained by overlapping two inner halves with the wire rope grooves facing each other is inserted into the cylindrical body, and the cylindrical body and the inner body are fixed by a fixture.

  The end of the wire rope is bound using the wire rope tying tool as follows. . That is, at least two ends of a wire rope having a stopper at its end are passed through the cylindrical body. The two inner halves are overlapped with at least two ends of the wire rope in the wire rope groove. The inner body into which the wire rope has been inserted is inserted into the cylindrical body. Thereby, the whole except for the edge part of the inner body (two inner half bodies) by which the wire rope was penetrated is covered with a cylindrical body.

  The cylindrical body and the inner body are fixed with a fixture. The fixture may be any one that prevents the relative positions of the two inner halves and the cylindrical body from shifting. In one embodiment, a hole is formed through each of the cylindrical body and the two inner halves, and the cylindrical body and the inner body are fixed by inserting a rod-shaped body into the hole. For example, bolts (and nuts), pins, etc. can be used as the rod-shaped body.

  The wire rope tying device according to the present invention is entirely covered by the cylindrical body except for the ends of the two inner halves, so that even if a strong impact is applied to the tying device or a strong tension is applied to the wire rope. Even so, it is unlikely that the binding tool (particularly the cylindrical body) will be damaged. The binding state (connected state) of the wire rope can be maintained satisfactorily.

  Preferably, the wire rope inserted through the plurality of wire rope insertion passages formed by the wire rope grooves can move in the longitudinal direction. In this case, the two inner halves overlap with each other in the wire rope groove so that the ends of the wire rope overlap each other by a predetermined length (double, triple, etc.). Combined.

  That the wire rope can move in the longitudinal direction includes that the wire rope insertion path is substantially the same as or slightly larger than the diameter of the wire rope. In any case, it is sufficient that the wire ropes are displaced in a direction away from each other when a tension is applied to the wire rope, and is determined according to the diameter of the wire ropes to be bound.

  When the wire rope is pulled in a direction away from each other due to the tension applied to the wire rope, the retaining stopper fixed to the end of the wire rope is displaced until it hits the binding tool. The tension applied suddenly to the wire rope is buffered by shifting the wire rope in the direction away from each other, and the wire rope is prevented from falling off from the binding tool. Needless to say, the retaining stopper fixed to the end of the wire rope is larger than the diameter of the wire rope insertion passage formed by the wire rope groove.

  In one embodiment, stepped portions are formed on both sides of the two inner halves so as to be fitted to each other when the two inner halves are overlapped. Since the movement of the two inner halves toward or away from each other is limited by the stepped portion, the effect of preventing the relative displacement between the inner body and the cylindrical body is reinforced. The step portions on both sides of the two inner halves are formed by the shapes constituting the convex portions (concave portions), the wall portions, and other steps. For example, if a side wall rising from the wire rope groove is formed on a part of both sides of the two inner halves, this side wall becomes a stepped portion.

  The wire rope tying tool according to the present invention (the method of binding the ends of the wire rope using the wire rope tying tool) can be used for a sound insulation wall, a soundproof wall, and other wall bodies. The wall body according to the present invention includes a plurality of support columns erected at intervals, a panel body stretched between adjacent support columns and having a wire rope insertion passage formed between both sides, and the wire rope of the panel body A plurality of wire ropes passed through the insertion path, wherein the one end of one wire rope and the other end of the other wire rope are end portions of the wire rope using the wire rope binding tool described above. And the both ends of the bundled wire rope are fixed to the column or the structure to which the column is fixed.

  When a vehicle collides with a wall body, for example, a sound insulation wall, and the sound insulation wall (post and panel body) is inclined, a load is applied to the wire rope. The wire rope tying tool is entirely covered with a cylindrical body except for the ends of the inner body (two inner halves), so even if a strong impact is applied to the sound insulation wall or the tying tool, or the wire rope has a strong tension. Even if is added, the possibility of breakage is low, and the bundled state (connected state) of the wire rope is well maintained. In addition, the wire rope insertion path in the inner body is such that the wire rope can move in the longitudinal direction, and the wire rope is bound by the binding tool so that the end of the wire rope overlaps the predetermined length outside the binding tool. As a result, when the vehicle collides with the sound insulation wall, the wire rope is pulled away from each other, and the retaining stopper fixed to the end of the wire rope is displaced until it hits the binding tool. The tension applied to the wire rope is buffered. Moreover, the movement (falling, moving, rotating, etc.) of the column and the panel body can be suppressed by the wire rope. The wire rope may be stretched through the support.

  FIG. 1 shows a perspective view of a sound insulation wall (sound insulation wall) provided along a side of a road as seen from the front side (road side).

  The sound insulation wall 1 includes a steel column 2 having a plate-like base 3 welded to its lower end, soundproof panels 4, 5, 6 and 7 which are stretched between adjacent columns 2 to form a wall, and adjacent columns.

In FIG. 4, only the binding tool 40 that binds (connects) the two wire ropes 20a and 20b (and the wire ropes 20a and 20b) is shown, and the remaining four wire ropes 20c to 20f are not shown. ing.

  As will be described later, the wire ropes 20a to 20f stretched below the sound insulation wall 1 are such that when the vehicle or the like collides with the sound insulation wall 1, the support 2 and the sound insulation panels 4 to 7 are splashed (the support 2 is This is to prevent falling from the road (damaged from the root) and is hereinafter referred to as a fall prevention wire rope. The wire ropes 10a to 10f stretched on the relatively upper part of the sound insulation wall 1 are the pillars 2 and the sound insulation panels 4 to centered on the fall prevention wire ropes 20a to 20f when the vehicle or the like collides with the sound insulation wall 1. 7 is for preventing rotation, and hereinafter referred to as a rotation preventing wire rope. The diameter of the fall prevention wire ropes 20a to 20f stretched at the lower part of the sound insulation wall 1 is larger than the diameter of the rotation prevention wire ropes 10a to 10f stretched at the relatively upper part of the sound insulation wall 1 (for example, a diameter of 12 mm). Slightly thick (for example, 18mm in diameter).

  The anti-rotation wire ropes 10a to 10f and the fall prevention wire ropes 20a to 20f are stretched over the entire width of the sound insulation wall 1, but the sound insulation wall 1 of this embodiment is provided over a relatively long distance. It is separated into two in the column 2 (B) (see FIG. 1) at the intermediate position. That is, the anti-rotation wire ropes 10a, 10b, and 10c bound by the two tying tools 30 are stretched between the strut 2 (A) at one end of the sound insulating wall 1 and the intermediate strut 2 (B). The anti-rotation wire ropes 10d, 10e, and 10f bound by the two binding tools 30 are stretched between the support 2 (C) at the other end from (B). Similarly, for the fall prevention wire ropes 20a to 20f, the fall prevention wire ropes 20a, 20b, and 20c bound by the two binding tools 40 between the support post 2 (A) and the intermediate support post 2 (B) are provided. The fall prevention wire ropes 20d, 20e, and 20f bound by the two binding tools 40 are stretched between the intermediate strut 2 (B) and the strut 2 (C).

  FIG. 8 shows a state in which one end of the anti-rotation wire rope 10c and one end of the anti-rotation wire rope 10d are fixed to the intermediate strut 2 (B). Terminal tools 71 each having a thread groove formed at one end (fixed end) of the anti-rotation wire ropes 10c and 10d are fixed. The screw shaft 52 is passed through the two holes formed in the web 2a of the intermediate column 2 (B), and the screw shaft 52 and the terminal tool 71 are connected (fixed). By fixing the screw shaft 52 to the web 2a with the nut 53, one end of each of the anti-rotation wire ropes 10c and 10d is fixed to the intermediate strut 2 (B).

  One end of the drop-preventing wire ropes 20c, 20d is also fixed to the intermediate strut 2 (B) in the same manner as described above.

  Returning to FIG. 4, one end of the anti-rotation wire rope 10 a is fixed to the column 2 (A) located at one end of the sound insulation wall 1. A terminal tool 71 having a thread groove formed at one end of the wire rope 10a for preventing rotation is fixed, and the screw shaft 52 is passed through the through hole 2d formed in the web 2a of the column 2 (A). The screw shaft 52 is fixed to the web 2 a of the support column 2 (A) by a nut 53. Similarly, one end of the fall prevention wire rope 20a is similarly provided with a terminal 72 having a thread groove fixed to one end of the fall prevention wire rope 20a and a through hole 2e formed in the web 2a of the support column 2 (A). The screw shaft 62 passed through is fixed, and the screw shaft 62 is fixed to the web 2 a of the support column 2 (A) by the nut 63.

  Although not shown in FIG. 4, one end of the rotation prevention wire rope 10f and the fall prevention wire rope 20f is fixed to the column 2 (C) located at the other end of the sound insulation wall 1 in the same manner as described above. .

  The one end of the wire ropes 10a and 10f for preventing rotation and the other end of the wire ropes 20a and 20f for preventing fall are replaced with other structures instead of being fixed to the columns 2 (A) and 2 (C) as described above. For example, you may make it fix using the anchor bolt etc. to the side wall of the concrete rail where the support | pillar 2 (A) and 2 (C) are fixed.

  The end of the anti-rotation wire rope bound (coupled) by the tying tool 30, that is, the other end of the anti-rotation wire rope 10a (the side opposite to one end fixed to the above-mentioned support 2 (A)), the wire rope Stoppers 11 are fixed to both ends of 10b (FIG. 4). The stopper 11 prevents the ends (bundling ends) of the wire ropes 10a, 10b... From being pulled out of the binding tool 30, and the binding (connection) between the wire ropes is prevented from being released (details will be described later). . Similarly, a stopper 21 is also fixed to the ends of the fall prevention wire ropes 20a, 20b,... Bound by the binding tool 40 (FIG. 4), and the connected wire ropes 20a, 20b,. Removal from the tool 40 is prevented.

  FIG. 9 shows a state in which the ends of the two anti-rotation wire ropes 10 a and 10 b are bound (connected) by the binding tool 30. FIG. 10 is an exploded perspective view of the binding tool 30. Although the dimensions are different, the binding tool 40 for binding the ends of the drop prevention wire ropes 20a, 20b,... Has the same structure as the binding tool 30. The binding tool 30 will be described.

  The binding tool 30 includes an inner upper half 31, an inner lower half 32, and an outer cylindrical body 33. The inner upper half 31, the inner lower half 32, and the outer cylindrical body 33 are all made of relatively hard high-strength carbon steel in which carbon, manganese, or the like is mixed in iron.

  On the lower surface of the inner upper half 31, two wire rope grooves 31c and 31d having arc-shaped cross-sectional shapes extending in parallel and separated by a wall portion 31e are formed. Two bolt holes 31a and 31b penetrating from the upper surface to the lower surface of the inner upper half 31 are formed in the wall portion 31e with a gap therebetween.

  On the upper surface of the inner lower half 32, two wire rope grooves 32c and 32d having arc-shaped cross-sectional shapes extending in parallel and separated by the wall 32e are formed, and the inner lower half is formed in the wall 32e. Two bolt holes 32a and 32b penetrating from the upper surface of 32 to the lower surface are formed at intervals.

  When the half halves 31 and 32 are overlapped with the wire rope grooves facing each other, the wire rope grooves 10a for rotation prevention are provided by the wire rope grooves 31c and 31d of the upper half 31 and the wire rope grooves 32c and 32d of the lower half 32. , 10b through which two wire rope insertion passages are formed.

  On both sides of the lower surface of the upper half body 31, a high side wall 31f formed from one end portion to the center of the upper half body 31 rises, and a low side wall 31g rises from the center to the other end portion. The boundary between the high side wall 31f and the low side wall 31g forms a step 31h.

  On the other hand, on both sides of the upper surface of the lower half 32, a high side wall 32f rises from the other end of the lower half 32 to the center, and a low side wall 32g rises from the center to one end. The boundary between the high side wall 32f and the low side wall 32g forms a step 32h.

  When the halves 31 and 32 are overlapped, the high side wall 31f on both sides of the lower surface of the upper half body 31 and the lower side wall 32g on both sides of the upper surface of the lower half body 32 are fitted, and the lower side walls of the upper half body 31 are lower on both sides. The side wall 31g and the high side wall 32f on both sides of the upper surface of the lower half 32 are fitted. Further, the step 31h of the upper half 31 and the step 32h of the lower half 32 face each other. The steps 31h and 32h limit the movement of the superposed upper half 31 and lower half 32 in the direction of approaching each other.

  Further, when the half halves 31 and 32 are overlapped, a cylindrical outer shape having a flat upper surface and lower surface is obtained. The outer cylindrical body 33 is slightly larger than the outer shape when the halves 31 and 32 are overlapped. Two bolt holes 33a and 33b are also formed on the upper surface and the lower surface of the outer cylindrical body 33 with a gap therebetween.

  Two anti-rotation wire ropes 10a and 10b are passed through the outer cylindrical body 33 in opposite directions. The ends of the two anti-rotation wire ropes 10a and 10b are inserted into the two wire rope grooves 32c and 32d of the inner lower half 32, respectively. At this time, for each of the two anti-rotation wire ropes 10a and 10b, the portions of the wire ropes 10a and 10b that are slightly separated from the stopper 11 are put into the two wire rope grooves 32c and 32d of the inner lower half 32, respectively. Keep it. Hereinafter, the portions of the anti-rotation wire ropes 10a and 10b from the stopper 11 to the binding tool 30 are referred to as extra length portions.

  The inner upper half 31 is overlaid on the inner lower half 32. Two anti-rotation wire ropes 10a and 10b also enter the wire rope grooves 31c and 31d on the lower surface of the inner upper half 31, respectively.

  After the two halves 31 and 32 are overlapped, the outer cylindrical body 33 is slid to the position of both halves 31 and 32, and the both halves 31 and 32 are placed in the outer cylindrical body 33. Thereafter, the bolts 34 and 35 are passed through the bolt holes 33a, 31a and 32a and the bolt holes 33b, 31b and 32b, respectively, and tightened with nuts 36 and 37 through washers 38 and 39, respectively. The binding (connection) of the ends of the two anti-rotation wire ropes 10a and 10b is completed.

  The diameters of the two wire rope insertion paths through which the anti-rotation wire ropes 10a, 10b formed by the wire rope grooves 31c, 31d, 32c, 32d formed in the upper half 31 and the lower half 32, respectively, are anti-rotation. The wire ropes 10a and 10b are slightly larger than or substantially coincident with the diameter of the wire ropes 10a and 10b. The ends of the anti-rotation wire ropes 10a and 10b can move in the binding tool 30 in the longitudinal direction.

  The diameter of the stopper 11 fixed to the ends of the rotation preventing wire ropes 10a and 10b is larger than the diameter of the wire rope insertion path through which the rotation preventing wire ropes 10a and 10b pass. When the anti-rotation wire ropes 10a and 10b are displaced away from each other, the stopper 11 comes into contact with the end of the binding tool 30 (both halves 31, 32), and the anti-rotation wire ropes 10a and 10b are bound. It will not fall out of the tool 30 (FIG. 11).

  For example, consider a case where a vehicle traveling on a road collides with a sound insulation wall 1 erected along the side of the road. When the vehicle collides with the sound insulation wall 1, there is a possibility that one or several columns 2, the soundproof panels 4 to 7 and the support member 8 passed between the columns 2 are inclined in the direction opposite to the road. Furthermore, when the impact is strong, there is a possibility that the support column 2 is fundamentally damaged (splashed). When the road is constructed on a bridge and there are other structures (for example, other roads, private houses, etc.) under the bridge, if the column 2 or the soundproof panels 4 to 7 and the support member 8 fall from the bridge , May cause a disaster (secondary disaster).

  The fall of the support columns 2, the soundproof panels 4 to 7 and the support member 8 from the bridge is effectively prevented by the drop prevention wire ropes 20a, 20b,. As described above, the drop-preventing wire ropes 20 a, 20 b... Are passed through the through holes 2 e formed in the lower portions of the plurality of columns 2 and the support members 8 fixed at both ends to the columns 2. The wire rope insertion passage 8d is stretched. For this reason, even if some of the plurality of struts 2 are damaged from their roots, the fall prevention wire ropes 20a, 20b,... Thus, the movement of the damaged support column 2 is restricted, and the fall from the bridge is prevented. Since the soundproof panels 4 to 7 and the support member 8 are fixed to the column 2, the soundproof panels 4 to 7 and the support member 8 do not fall from the bridge.

  If only the fall prevention wire ropes 20a, 20b,... Are provided, the fall prevention wire ropes 20a, 20b,. There is a risk of rotating around the bridge as an axis (collapse of nearly 180 degrees, suspended state). This is prevented by the anti-rotation wire ropes 10a, 10b. The anti-rotation wire ropes 10a, 10b,... Are stretched through the through hole 2d of the support column 2 and the wire rope insertion passage 4a of the soundproof panel 4 at a relatively upper portion of the sound insulation wall 1. 10b... Restricts the movement of the upper portion of the support column 2 and the soundproof panels 4 to 7, and prevents the support column 2 and the soundproof panels 4 to 7 from being greatly inclined (rotated).

  When the support column 2, the soundproof panels 4 to 7 and the support member 8 are inclined, or when the support column 2 is damaged from the root, the anti-rotation wire ropes 10a, 10b... Are pulled away from each other. As described above, the end portions of the anti-rotation wire ropes 10a, 10b,... Are bound by the binding tool 30 with the extra length secured in advance, and can move in the binding tool 30 in the longitudinal direction. When the prevention wire ropes 10a, 10b,... Are pulled, the wire ropes are displaced until the stopper 11 hits the binding tool 30. Thereby, the tension applied suddenly to the anti-rotation wire ropes 10a, 10b... Is buffered. Since the state of being bound (connected) by the stopper 11 is maintained, there is no possibility that the ends of the rotation preventing wire ropes 10a, 10b,. The same applies to the fall prevention wire ropes 20a, 20b.

  The binding tool 30 for binding the anti-rotation wire ropes 10a, 10b,... Is entirely covered with the outer cylindrical body 33 except for the side portions of the inner upper half 31 and the inner lower half 32. Since the body 33 and the inner upper half 31 and the inner lower half 32 are fixed by bolts 34, 35 and nuts 36, 37, it is assumed that strong tension is applied to the wire ropes 10a, 10b,. However, even if a strong impact is applied to the binding tool 30, the possibility that the outer tubular body 33 will be damaged is low, and the rotation preventing wire ropes 10a, 10b,. The nature is low. This also applies to the binding tool 40 that binds the fall prevention wire ropes 20a, 20b.
