[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2002-4635 Summary of the Invention [Problem to be solved by the invention]

[0004] The device described in Patent Document 1 is attached to an existing connecting column member (the existing portion of an assembled column). Furthermore, each time a connecting column member is added, the device is removed from the existing connecting column member and reattached to the most advanced (upper) existing connecting column member. However, the work of removing and reattaching the device must be performed at a higher elevation as more connecting column members are added, making the work more difficult and requiring more effort and time.

[0005] An object of the present invention is to provide a pole mounting tool that can efficiently erect an assembled pole by adding connecting pole members. [Means for solving the problem]

[0006] The erection pole tool is used to erect an assembled pole formed by connecting extension pole members, and includes a support pole supporting a lifting part that lifts the extension pole member, and first and second fixing parts fixed to the support pole to attach and detach the support pole to the extension pole member. The second fixing part can be fixed and detached to the support pole, and includes a rotatable rotating body on which a linear object can be hung. The support pole and the second fixing part are slidable relative to each other in the longitudinal direction of the support pole, i.e., one can slide relative to the other.

[0007] The support may include a reinforcing member for reinforcing the support at a portion where the first fixing portion and the second fixing portion are fixed. The support may be tubular, and the reinforcing member may be tubular and fixed inside the support.

[0008] The post fixture may have a through-hole through which the post can be passed, and may be provided with an auxiliary support part that can be attached and detached to the end of the extension post member. [Effects of the Invention]

[0009] The pole erection tool allows the erection of assembled poles to be carried out more efficiently and safely than conventional devices. [Brief explanation of the drawings]

[0011] Hereinafter, an embodiment of the post fixture will be described with reference to the drawings. The post fixture 1 is used to erect an assembled post formed by connecting joint post members, and as shown in Figures 1 and 2, includes a support 10, an attachment part 30, a first fixing part 40, and a second fixing part 50.

[0012] The support 10 is a column-shaped structure to which a lifting section 80 for lifting a connecting column member can be attached or which includes the lifting section 80. In this embodiment, as shown in FIGS. 1 and 3, the support 10 includes a first support 11, a second support 12 detachably connected to the first support 11 by a support attachment / detachment means, a reinforcing member 25, and an attachment section 30. The first support 11 and the second support 12 are both tubular and made of a metal such as steel. The outer and inner diameters of the first support 11 and the second support 12 are substantially the same. However, the rear end of the second support 12 forms an insertion section 12a that can be inserted into the first support 11, and its outer diameter is equal to or smaller than the inner diameter of the first support 11, and in this case, is substantially the same as the inner diameter of the first support 11. A ring-shaped guy wire attachment section 19 is provided at the tip of the second support 12 for attaching a guy wire 90 such as a rope.

[0013] When the insertion portion 12a of the second support 12 is inserted into the first support 11, a pair of connecting holes (support detachment means, not shown) are provided opposite each other in the portion into which the insertion portion 12a of the second support 12 and the insertion portion 12a of the first support 11 are inserted, and penetrate both support portions together in a direction perpendicular to the longitudinal direction (axial direction) of the support portions (first support 11 and second support 12) of the support 10. In addition, a pair of fixing holes (fixing portion fixing and detachment means) is provided opposite each other in both or one of the first support 11 and the second support 12, and penetrates the support portion in a direction perpendicular to the longitudinal direction. A plurality of pairs of fixing holes may be provided at intervals in the longitudinal direction of the support 10. In this embodiment, the fixing holes are composed of a first fixing hole 13 that penetrates the first pillar 11 in the left-right direction at the rear end side of the first pillar 11, and a second fixing hole 15 that penetrates the first pillar 11 in the left-right direction at the tip side of the first fixing hole 13.

[0014] Fixing position marks 17 indicating the positions for fixing the second fixing portion 50 are provided around the second fixing hole 15 on the outer peripheral surface of the first support column 11. In this embodiment, the fixing position marks 17 are linear or band-like marks extending circumferentially on the outer peripheral surface of the first support column 11, and are provided in pairs at a distance from each other at the front and rear of the second fixing hole 15. The pair of fixing position marks 17, 17 are spaced apart so that the second fixing portion 50 can be fixed between them. Note that a pair of fixing position marks 17, 17 may also be provided at the front and rear of the first fixing hole 13, similar to the pairs at the front and rear of the second fixing hole 15.

[0015] The support 10 includes a reinforcing member 25 that reinforces the support 10 at the portion where the first fixing portion 40 and the second fixing portion 50 are fixed. In this embodiment, the reinforcing member 25 is made of a metal such as steel and is a rectangular tube with a square cross section as shown in FIGS. 3 and 4 . The reinforcing member 25 is provided inside the first support 11 to which the first fixing portion 40 and the second fixing portion 50 are fixed. The diagonal length of the reinforcing member 25 is approximately the same as the inner diameter of the first support 11. The reinforcing member 25 is inserted into the first support 11 and fixed to the first support 11 by welding or the like. The reinforcing member 25 is provided inside the first support 11 from the rear end of the first support 11 to the portion where the insertion portion 12a of the second support 12 is inserted. The reinforcing member 25 also has a first fixing hole 13 and a second fixing hole 15 that overlap the first fixing hole 13 and the second fixing hole 15 of the first support 11, respectively. That is, the first fixing hole 13 and the second fixing hole 15 penetrate the first support column 11 and the reinforcing member 25 together.

[0016] The mounting portion 30 is used to attach a lifting portion 80 that lifts the connecting column members that constitute the assembled column. In this embodiment, the mounting portion 30 is made of metal such as steel, and includes a mounting base 32 and an arm portion 34, as shown in FIGS. 1 and 3 . The mounting base 32 is attached to the tip side of the second support column 12, in other words, the tip side of the support column 10. The arm portion 34 extends from the mounting base 32 in a direction approximately perpendicular to the longitudinal direction of the second support column 12. The arm portion 34 also includes an arm hanger portion 36 having an annular hanger portion on which the lifting portion 80 can be hung. A support column marker 38 is provided on the side of the arm portion 34. The support column marker 38 has an arrow pointing in one direction perpendicular to the longitudinal direction of the support column 10 and the penetration direction of the second fixing hole 15. The support post mark 38 may be provided on any part of the support post 10, for example, on the first support post 11 or the second support post 12.

[0017] The lifting part 80 is, for example, a pulley, and a hook 82 of the pulley is hung on the hanging part of the arm hanging part 36. The pulley is provided with a lifting part rope 84 that is hung on the pulley, and by pulling the lifting part rope 84, an object attached to the lifting part rope 84 can be lifted. The lifting part 80 may also be a roller or the like that is directly attached to the support 10, in which case the mounting part 30 is not necessary.

[0018] The support 10 is formed by inserting the insertion portion 12a of the second support 12 into the first support 11 from one end side (tip side) of the first support 11, and with their respective connecting holes overlapping, passing a bolt 21 (support attachment / detachment means) through the connecting hole and fastening a nut 23 (support attachment / detachment means) to the bolt 21. In the formed support 10, the first support 11 and the second support 12 are approximately coaxial.

[0019] The pole fixture 1 has a support 10 which comprises a first support 11 and a second support 12 which is detachably connected to the first support 11, and when the connection is released, the pole fixture 1 becomes compact, making it easy to transport.

[0020] The first fixing portion 40 and the second fixing portion 50 are used to attach and detach the support 10 to the extension member.

[0021] In this embodiment, the first fixing portion 40 is detachable (fixed and unlocked) from the support 10 and the extension member. The first fixing portion 40 is made of metal such as steel, and includes a first base portion 41, a pair of first connecting portions 42, a first abutment portion 43, a linear object mounting portion 44, a first mark 45, and a first extension member fixing portion 46, as shown in Figures 1, 2, and 5.

[0022] The first base 41 is cylindrical, with its axis parallel to the vertical direction. The inner diameter of the first base 41 is equal to or smaller than the outer diameter of the first support 11, allowing the support 10 to pass through it. Here, the inner diameter of the first base 41 is approximately the same as the outer diameter of the first support 11. The first base 41 is provided with a pair of opposing first base holes 41a (fixed portion attachment / detachment means) that penetrate the first base 41 in the left-right direction.

[0023] The first connecting portions 42 are plate-shaped and extend forward at intervals in the vertical direction from the first base portion 41. A first abutment portion 43 is connected to the tip of each first connecting portion 42.

[0024] The first abutment portion 43 includes a cylindrical abutment portion main body 43a. A pair of abutment bodies 43b, which are mountain-shaped in plan view and extend in the vertical direction, are provided on the front surface of the abutment portion main body 43a at a distance from each other in the left-right direction. By configuring the first abutment portion 43 in this manner, the cylindrical extension column member contacts between the abutment portion main body 43a and the pair of abutment bodies 43b, 43b, allowing the first fixing portion 40 to firmly abut against the extension column member.

[0025] A handle-shaped linear object attachment portion 44 is provided at the rear of the first base portion 41.

[0026] The first fixing portion 40 is provided with a first mark 45. In this embodiment, the first mark 45 is a mark provided on the side surface of the first abutment portion 43, and the marking includes an arrow. The direction of the arrow of the first mark 45 is set to be the same as the direction of the arrow of the support mark 38 when the first fixing portion 40 is fixed to the support 10. Note that the direction of the arrow of the first mark 45 may be opposite to the direction of the arrow of the support mark 38.

[0027] The first extension member fixing portion 46 is used to fix (attach / detach) the first fixing portion 40 attached to the support 10 to the extension member. In this embodiment, the first extension member fixing portion 46 is a so-called lashing belt, and includes a flexible, belt-shaped band portion 46a made of synthetic fiber or the like, and a buckle 46b attached to the band portion 46a. The buckle 46b is of a ratchet type. The first extension member fixing portion 46 has the band portion 46a passed through the buckle 46b, and by operating the buckle 46b, the band portion 46a can be tightened or loosened, or the band portion 46a can be removed from the buckle 46b.

[0028] The first fixing part 40 can be attached to and detached from the support 10, here the first support 11. The first fixing part 40 is fixed to the support 10 (first support 11) by passing the support 10 through the first base 41, aligning the first base hole 41a with the first fixing hole 13 so that the arrow of the first mark 45 is oriented in the same direction as the arrow of the support mark 38, passing a bolt 48 (fixing part attaching / detaching means) through the first base hole 41a and the first fixing hole 13, and fastening a nut (fixing part attaching / detaching means, not shown). Furthermore, by removing the nut from the bolt 48 and removing the bolt 48 from the first base hole 41a and the first fixing hole 13, the first fixing part 40 is released from its attachment to the support 10 (first support 11) and can be removed from the support 10.

[0029] The first fixing part 40 is fixed to the existing connecting post member by bringing the first abutting part 43 into contact with the existing connecting post member (the existing part of the assembled post), passing the band-like part 46a of the first connecting post member fixing part 46 through the space surrounded by the first base part 41, the first abutting part 43 and the pair of first connecting parts 42, wrapping it around the connecting post member, passing it through the buckle 46b, and operating and tightening the buckle 46b. From this state, the fixing to the existing connecting post member can be released by operating the buckle 46b to loosen the fastening of the band-like part 46a while it is still wrapped around the first fixing part 40 and the existing connecting post member, or by removing the band-like part 46a from the buckle 46b and removing the band-like part 46a from the connecting post member and the first fixing part 40.

[0030] In this embodiment, the second fixing part 50 and the support 10 are slidable relative to each other in the longitudinal direction of the support 10, and are attachable to and detachable from (fixed and unlocked from) the support 10 and the extension member. The second fixing part 50 is made of metal such as steel, and includes a second base part 51, a pair of second connecting parts 52, a second abutment part 53, a second mark 55, a second extension member fixing part 56, and a rotating part 57, as shown in Figures 1, 2 and 6.

[0031] In addition to the configuration of the first base 41, the second base 51 has a temporary fixing portion 51b for temporarily fixing the second fixing portion 50 to the support 10. The temporary fixing portion 51b has a female thread provided on the inner surface of a hole that penetrates the peripheral wall of the second base 51 in the left-right direction, and a bolt that has a male thread that corresponds to the female thread and is attached to the female thread. The second base 51 also has a second base hole 51a (fixing portion attachment / detachment means) that corresponds to the first base hole 41a of the first base 41.

[0032] The second connecting portion 52 is similar to the first connecting portion 42, and a description thereof will be omitted. The second abutting portion 53 is similar to the first connecting portion 42, and includes an abutting portion main body 53a and a pair of abutting bodies 53b, 53b, and a description thereof will be omitted. The second marking 55 is similar to the first marking 45, and a description thereof will be omitted. The second extension column member fixing portion 56 is similar to the first extension column member fixing portion 46, and includes a belt-shaped portion 56a and a buckle 56b, and a description thereof will be omitted.

[0033] The rotating unit 57 includes a pair of rotating body support parts 57a, 57a spaced apart in the left-right direction and extending rearward from the second base part 51, and a rotating body 57b rotatably supported by the pair of rotating body support parts 57a, 57a at the rear of the second base part 51. The rotating body 57b has a rotation axis that is parallel to the left-right direction. A flexible linear body 70 such as a rope can be hung on the rotating body 57b.

[0034] The second fixing part 50 can be attached to and detached from the support 10, in this case the first support 11. The second fixing part 50 is fixed to the support 10 (first support 11) by passing the first support 11 through the second base 51, aligning the arrow of the second mark 55 with the arrow of the support mark 38, and moving the second fixing part 50 so that it fits between the pair of fixing position marks 17, 17, aligning the second base hole 51a with the second fixing hole 15, and passing an L-shaped pin 58 (fixing part attaching / detaching means) through the second base hole 51a and the second fixing hole 15. Furthermore, by removing the pin 58 from the second base hole 51a and the second fixing hole 15, the second fixing part 50 is released from its fixation to the support 10 (first support 11), allowing one of the second fixing part 50 and the support 10 to slide relative to the other, and further enabling the second fixing part 50 to be removed from the support 10. Furthermore, the second fixing part 50 can be temporarily fixed to any position in the longitudinal direction of the support 10 (first support 11 and second support 12) by turning the temporary fixing part and pressing against the support 10, and the temporary fixation can be released by rotating the temporary fixing part in the opposite direction.

[0035] The method of fixing and releasing the second fixing portion 50 to an existing connecting column member using the second connecting column member fixing portion 56 is the same as that using the first connecting column member fixing portion 46 of the first fixing portion 40, so explanation will be omitted here.

[0036] When the support 10 is fixed to the connecting member by the first fixing part 40 and the second fixing part 50, the longitudinal direction (axial direction) of the support 10 becomes approximately parallel to the longitudinal direction (axial direction) of the assembled column. In addition, the second fixing part 50 is located further forward (upper) of the support 10 than the first fixing part 40.

[0037] When using the pole fitting 1 to lift a connecting pole member, if it is desired to have the support 10 firmly supported by the existing connecting pole member, an auxiliary support part 60 may be used.

[0038] The auxiliary support part 60 has a through-hole 61b through which the support 10 can be passed and is detachably fixed to the end of the extension member. In this embodiment, the auxiliary support part 60 includes an auxiliary support base 61 and an auxiliary support fixing part 63. As shown in FIG. 7, the auxiliary support base 61 includes a base main body 61a and a through-hole 61b. The base main body 61a has flat surfaces at the front and rear, and the left and right ends are bent forward. The base main body 61a is provided with a guide hole (not shown) that penetrates in the front-rear direction. The through-hole 61b is approximately C-shaped in plan view, with one end connected to the back of the base main body 61a, allowing the support 10 to be passed inside. The inner width of the through-hole 61b is equal to or greater than the outer diameter of the second support 12, and in this case, is approximately the same as the outer diameter of the second support 12.

[0039] The auxiliary support fixing portion 63 is used to fix (attach / detach) the auxiliary support portion 60 to the connecting column member. The auxiliary support fixing portion 63 includes a guide portion 63a, a movable body 63b, and a movement restricting portion 63c. Here, the guide portion 63a is a bolt. The head of the guide portion 63a is larger than the guide hole, and the body can be passed through the guide hole. The guide portion 63a is inserted into the guide hole from the back side of the base main body 61a, and the body protrudes forward from the base main body 61a. The movable body 63b includes a through hole (not shown), through which the guide portion 63a is passed, allowing it to move back and forth along the guide portion 63a. The movement restricting portion 63c restricts movement of the movable body 63b and prevents the movable body 63b from coming off the guide portion 63a. Here, the movement restricting portion 63c is a nut fastened to the guide portion 63a (bolt). When the movement restricting portion 63c is rotated in a direction in which it is tightened relative to the guide portion 63a, the moving body 63b is pushed by the movement restricting portion 63c and moves toward the base main body 61a.

[0040] When the assembled column is a panzamast 100 (assembled steel pipe column) formed by connecting unit masts 110 (steel pipes) which are connecting column members, the auxiliary support part 60 is attached to the column 10 and the existing unit mast 110 by fixing the column 10 to the existing unit mast 110 (steel pipe) using both or one of the first fixing part 40 and the second fixing part 50, passing the column 10 from its tip through the through part 61b, hooking the part surrounded by the base main body 61a, guide part 63a and movable body 63b onto the tip of the existing unit mast 110, rotating the movement restricting part 63c in the tightening direction, and clamping the peripheral wall of the unit mast 110 between the base main body 61a and the movable body 63b. Conversely, by rotating the movement restricting portion 63c in the loosening direction to release the clamping of the peripheral wall of the unit mast 110 between the base body 61a and the movable body 63b, and then moving the auxiliary support portion 60 upward to remove it from the support 10 and the unit mast 110, the auxiliary support portion 60 can be removed from the support 10 and the unit mast 110.

[0041] Next, a method for erecting an assembled column using the erection tool 1 will be explained with reference to Figures 1 and 8. Here, the assembled column is assumed to be a panzamast 100 formed by connecting unit masts 110 (steel pipes) that are connecting column members in their longitudinal (axial) direction. The lifting part 80 is assumed to be a pulley. At least the lowest unit mast 110 has already been constructed using conventional methods. The first fixing part 40 and the second fixing part 50 are assumed to have been fixed to the support 10 in advance.

[0042] In the first step, as shown in Figure 1, the pole fixture 1 is attached to the existing panzamast 100 (unit mast 110) at a position where the newly connected unit mast 110 can be lifted. Specifically, first, the first abutment portion 43 of the first fixing part 40 and the second abutment portion 53 of the second fixing part 50, which are fixed to the support 10, are abutted against the existing unit mast 110. Next, the first fixing part 40 is fixed (fastened) to the existing unit mast 110 by the first extension member fixing part 46 and the second fixing part 50 is fixed (fastened) to the existing unit mast 110 by the second extension member fixing part 56. In addition, a linear body 70 such as a rope is hung on the rotating body 57b of the second fixing part 50, and one end of the linear body 70 is passed through the space surrounded by the second base part 51, the second abutment portion 53, and the pair of rotating body support parts 57a, 57a and attached to the linear body attaching part 44 of the first fixing part 40. One end of the linear body 70 may be attached to the support 10. The lifting part 80 is attached by hanging the hook 82 of the lifting part 80 on the arm hanging part 36 of the mounting part 30. If necessary, one or more guy wires 90 such as ropes are attached to the guy wire mounting part 19 of the support 10 to support the support 10.

[0043] In the second step, as shown in Figures 8(A) and 8(B), the unit mast 110 to be newly connected is lifted by the lifting part 80 and connected to the existing unit mast 110. Specifically, one end of the lifting rope 84 hung on the lifting part 80 is connected to the unit mast 110 to be lifted. Furthermore, if a guy wire 90 is used, one end of the guy wire 90 attached to the support pole 10 is fixed to the ground while being inclined relative to the support pole 10. Next, the other end of the lifting rope 84 is pulled by an operator or with a winch or the like to lift the unit mast 110 (see Figure 8(A)). If the auxiliary support section 60 is attached to the support column 10 and the existing unit mast 110, remove the auxiliary support section 60, align the rear end of the lifted unit mast 110 with the front end of the existing unit mast 110, and connect the lifted unit mast 110 to the existing unit mast 110 (see Figure 8(B)). Next, remove the lifting section rope 84 from the lifted unit mast 110.

[0044] In the third step, as shown in Figures 8(C) to 8(E), the pole tool 1 is moved to a position where the newly connected unit mast 110 can be lifted and placed on the existing unit mast 110. Specifically, if an auxiliary support part 60 is used, the auxiliary support part 60 is attached to the tip (uppermost end) of the existing unit mast 110 and to the support pole 10 (see Figure 8(C)). Also, if one end of the guy wire 90 is fixed to the ground, it is released from the ground. Next, the buckle 56b of the second extension member fixing part 56 is operated, and with the band-shaped part 56a wound around the panza mast 100, in other words, with the band-shaped part 56a passed through the buckle 56b to form a loop, the fastening of the second extension member fixing part 56 to the existing unit mast 110 is loosened. Furthermore, the pin 58 that secures the second fixing part 50 to the support pole 10 is removed, and if the second fixing part 50 is secured to the support pole 10 by the temporary fixing part 51b, the temporary fixing part 51b is also released, releasing the second fixing part 50 from the support pole 10. Next, the second fixing part 50 is moved (slid) upward relative to the support pole 10, and the second fixing part 50 is temporarily secured to the support pole 10 by the temporary fixing part 51b. Furthermore, the second fixing part 50 is secured to the existing unit mast 110 by the second extension member securing part 56 (see Figure 8(D)). Next, the buckle 46b of the first extension member securing part 46 is operated, and with the band-shaped part 46a wound around the panzamast 100, the fastening of the first extension member securing part 46 to the existing unit mast 110 is loosened. Next, the linear body 70 is pulled by an operator or a winch or the like to move the support 10 upward together with the first fixing part 40, and the second fixing hole 15 is aligned with the second base hole 51a. The pin 58 is then passed through these holes to fix the second fixing part 50 to the support 10 (see FIG. 8(E)). The first fixing part 40 is then fixed to the existing unit mast 110 by the first extension member fixing part 46, and the second fixing part 50 is fixed to the existing unit mast 110 by the second extension member fixing part 56 (see FIG. 8(E)). Here, if the second fixing hole 15 cannot be aligned with the second base hole 51a when the support 10 is moved upward together with the first fixing part 40, the first fixing part 40 is first fixed (fastened) to the existing unit mast 110 by the first extension member fixing part 46. Next, the temporary fixing portion 51b is released from the support 10, and the second extension member fixing portion 56 is loosened from the existing unit mast 110. Next, with the first fixing portion 40 and the support 10 fixed to the existing unit mast 110, the second fixing portion 50 is moved so that the second fixing hole 15 is aligned with the second base hole 51a, and the pin 58 is passed through these holes to fix the second fixing portion 50 to the support 10.

[0045] Steps 2 and 3 are repeated until all unit masts 110 have been connected.

[0046] The pole mounting tool 1 can also be applied to the dismantling of assembled poles. When dismantling an assembled pole, the most distal end of the existing unit masts 110 is removed one by one. When dismantling an assembled pole, in step 1 above, the pole mounting tool 1 is attached to the existing panzamast 100 at a position where the unit mast 110 to be removed can be lowered from the existing panzamast 100 (unit mast 110). In step 2 above, the connection of the unit mast 110 to be removed from the existing panzamast 100 (unit mast 110) is released, and the unit mast 110 to be removed is lowered by the lifting part 80. In step 3 above, the pole mounting tool 1 is moved to a position where the new unit mast 110 to be removed can be lowered.

[0047] According to the pole erection tool 1, when the pole 10 is moved relative to the existing connecting pole member, the pole 10 can be moved by pulling the linear body 70 which is attached directly or indirectly to the pole 10 and hung on the rotating body 57b. Therefore, there is no need for the worker to directly move the pole 10 at a high altitude as with conventional devices, and pole erection work can be carried out efficiently and safely.

[0048] Furthermore, according to the building pole device 1, the support 10 is provided with a reinforcing member 25 that reinforces the support 10 at the portion where the first fixing portion 40 and the second fixing portion 50 are fixed, thereby improving the strength of the support 10.

[0049] Furthermore, according to the construction pole tool 1, the support 10 and the reinforcing member 25 are tubular, and the reinforcing member 25 is fixed inside the support 10, which makes the construction pole tool 1 lighter, making it easier to transport the construction pole tool 1 and allowing pole erection work to be carried out more efficiently.

[0050] Furthermore, the pole erection tool 1 is provided with an auxiliary support portion 60, which allows the pole 10 to be firmly supported by the existing connecting pole member, making pole erection work even safer and more efficient.

[0051] Furthermore, according to the post fixture 1, by providing the post 10 with the fixing position mark 17, the second fixing part 50 can be easily and quickly fixed to the post 10 even if the fixing position of the post fixture 1 to the existing connecting post member post is at a high place. Also, by displaying arrows on the post mark 38, the first mark 45, and the second mark 55, and by making the arrows on the post mark 38, the first mark 45, and the second fixing part 50 point in the same or opposite directions when fixing the first fixing part 40 and the second fixing part 50 to the post 10, the first fixing part 40 and the second fixing part 50 can be easily and quickly fixed to the post 10 in the appropriate orientation.
