  The present invention relates to a building pillar tool for a panther mast and a method for building the same, and more particularly to a panzer mast that can be assembled and built as prescribed.

Conventionally, in the case of a mountain that cannot enter a building pole vehicle or the like that stands a utility pole, instead of a general single utility pole, it is formed in a straight cylindrical shape with openings at both ends and from the tip In addition, a panzer mast is assembled by stacking so-called straight tubular frustoconical unit members that are open so that the base end side has a large area, and is used in the same manner as a utility pole (for example, patents). Reference 1).
JP-A-5-207629

  However, in such a conventional panzer mast building column, when the straight tubular frustoconical members are sequentially stacked in a nested manner so as to be continuous in the length direction, the distal end portion of the upper straight tubular frustoconical member is arranged. Since it is assembled by driving it with a mallet or the like, it is difficult to combine it by fitting it evenly in the circumferential direction, and the assembly shape may change due to the load of the article attached after the building pillar.

  When the assembly shape of the panther mast is changed in this way, for example, the steadying wire is loosened. In addition, if a part of the tip of the straight tubular frustoconical member is deformed by striking a mallet or the like, it may not be able to be assembled or may not be driven to such an extent that sufficient strength can be obtained. is there.

  Accordingly, the present invention provides a building pillar tool for a panther mast and a method for building the panther mast that can easily realize the assembly and construction of the panzer mast as prescribed, and to make the panther mast easier to use. And

And traction means for traction in a direction.

  In this invention, for example, in the direction of shortening the length of the linear member between the base plate member by hooking hooks at three or more locations at substantially equal intervals, at the opening end portion of the distal end portion of the straight tubular trapezoidal member, At the same time, or by changing the work location and repeating the gradual pulling, the depth of combining the openings can be fitted and joined while being uniform in the entire circumferential direction. Therefore, the panther mast can be assembled into a prescribed shape as designed, and the panther mast having a desired strength can be installed.

  In addition to the specific matter of the first invention, the second invention of the panther mast building tool for solving the above-mentioned problems is that the hook is hook-shaped so that it can be hooked to the opening end of the tip of the straight tubular trapezoidal member. A hook-shaped portion that bends to the hook shape, and a connecting portion that is disposed on the opposite side of the hook shape and is connected to the linear member of the traction means. The inner surface portion facing the outer surface is formed in a wide shape.

  In the present invention, the hook-shaped portion of the hook hooked on the opening end portion of the front end portion of the straight tubular trapezoidal member is a wide inner surface portion, and comes into contact with the inner surface, the end surface and the outer surface of the opening end portion, and the traction force The opening portions can be combined to a desired depth while avoiding the deformation of the opening end portion receiving a traction force in a small area. Therefore, the panther mast can be more reliably assembled into the specified shape as designed with the desired strength without deforming the open end of the straight tubular trapezoidal member.

  Here, this hook is not limited to a straight tubular trapezoidal member, but can also be used as a hook that hooks on an opening end of the plate-like material of a member having an opening surrounded by the plate-like material. It can also be used when it is necessary to pull the open end in a substantially parallel direction without deforming the material.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, the best embodiment of the invention will be described with reference to the drawings. 1-6 is a figure explaining one Embodiment of the tool for building pillars of a panther mast and the building pillar method of a panther mast based on this invention.

  First, a straight tubular trapezoidal member for assembling a panther mast will be described. In FIG. 1, the straight tubular trapezoidal member 100 is formed in a linear cylindrical shape having openings at both ends, and is formed in a truncated cone shape having a larger area opening on the base end 102 side than the distal end 101. Yes.

  The straight tubular trapezoidal member 100 can be assembled by stacking the distal end portion 101 so as to cover the proximal end portion 102 of another straight tubular trapezoidal member 100, and as shown in FIG. It is possible to achieve a desired height by sequentially standing and combining the manufactured ones on the plate-like base plate member 200 shown in FIG.

  Next, the building pillar tool of the panther mast will be described. This panzer mast building pillar tool includes a hook 10 shown in FIG. 4 and a traction machine (traction means) 30 shown in FIG. 5. The straight tubular trapezoidal member 100 is mounted on the base plate member 200. It is used when building panther masts that are stacked together.

  As shown in FIG. 4, the hook 10 includes a hook-shaped portion 11 that bends into a hook shape so as to be hookable at the opening end portion of the distal end portion 101 of the straight tubular trapezoidal member 100, and an extension portion 12 that continues to the hook-shaped portion 11. And is formed into a shape having.

  The hook 10 is fixed to the inner surface of the hook-shaped portion 11 which is opened in a U-shape by welding a wide plate-like member 13 similarly formed in a U-shape. A through hole 12a is opened at the end (opposite side of the hook-shaped portion 11), and for example, a ring member (connecting portion) 14 capable of hooking a hook 31a of a traction machine 30 described later is attached to the through hole 12a. ing.

  Here, the base plate member 200 used in the present embodiment, as shown in FIG. 3, has a base end portion 102 so that the base end portion 102 of the straight tubular trapezoidal member 100 can be placed on the lower side. Is formed in a square having a side that is approximately twice the diameter of the base end portion 102, and at three locations that are equally spaced around the base end portion 102, for example, The U-shaped member 21 is fixed by welding or the like so that a hook 31a of the traction machine 30 described later can be hooked.

  As shown in FIG. 5, the traction machine 30 has a hook 31 a formed in a general hook shape that can be hooked on the ring member 14 of the hook 10 or the U-shaped member 21 of the base plate member 200, and is connected to the tip portion. Two hooking wires (linear members) 31 and a traction machine main body 32 that pulls the hooking wire 31, and the traction machine main body 32 has a clip 35 a that holds the hooking wire 31 at the tip. For example, a rotating drum with a built-in ratchet mechanism so that the two pulling wires (linear members) 35 connected to each other and the pulling wires 35 are connected to freely rotate in one direction and restrict reverse rotation. 36 and a lever 37 that applies a force for rotating the rotating drum 36 in one direction.

  As a result, the traction machine 30 can rewind the lever 37 of the traction machine main body 32 so that the rotary drum 36 is rotated in one direction while restricting reverse rotation, and the traction wire 35 can be wound up. It can be pulled in the direction of shortening the distance between the hooks 31a of the hook wire 31 connected by the clip 35a at the tip of the wire 35. The rotating drum 36 can rewind the traction wire 35 that has been wound up by releasing the restriction on reverse rotation, and by this release, free rotation in one direction by the lever 37 can be allowed again. Designed.

  Next, a method for building a panther mast will be described. First, a plurality of straight tubular trapezoidal members 100 having different diameters, three hooks 10, one base plate member 200, and three sets of traction machines 30 (the hook wire 31 and the traction machine main body 32) are prepared. To do.

  Next, as shown in FIG. 6, the base end of the straight tubular trapezoidal member 100 having the maximum diameter prepared on the base plate member 200 is formed after the base plate member 200 is horizontally placed by excavating the building pillar portion of the panther mast. After placing the unit 102 in a standing state, the tip 102 of the straight tubular trapezoidal member 100 is stacked and combined so as to cover the proximal end 102 of the next straight tubular trapezoidal member 100.

  Next, the hook 10 is hooked on the opening end of the tip 101 of the upper straight tubular trapezoidal member 100, and the hook 31 a at the tip of one hook wire 31 of the traction machine 30 is hooked on the ring member 14 of the hook 10. Further, the hook 31 a at the tip of the other hooking wire 31 of the traction machine 30 is hooked on the U-shaped member 21 of the base plate member 200. Thereafter, the clip 35 a at the tip of each traction wire 35 of the traction machine main body 32 is connected to each of the hooking wires 31. This operation is performed for each U-shaped member 21 of the base plate member 200 so that the hooks 10 are hooked on the opening end portion of the top end portion 101 of the upper straight tubular trapezoidal member 100 so as to be evenly spaced. By rotating the lever 37 of the traction machine main body 32 and winding the traction wire 35, the entire length of the wire 31, 35 between the hook 10 and the U-shaped member 21 of the base plate member 200 is not loosened. The hook 10 of the front end 101 of the upper straight tubular trapezoidal member 100 is shortened and is set so as to be able to be pulled in the direction in which the hook 10 is brought close to the base plate member 200.

  Next, the operation of further rotating the lever 37 of the traction machine main body 32 to wind the traction wire 35 is repeated for each of the three traction machines 30 around the straight tubular trapezoidal member 100, so that the upper straight tubular trapezoidal member is The three hooks 10 hooked to the open end of the tip 101 of the 100 are sequentially pulled in a direction to approach the hooks 31a hooked to the three U-shaped members 21 of the base plate member 200, and the upper side (second ) Of the straight tubular trapezoidal member 100 of the lower tubular straight trapezoidal member 100, the top end 101 of the lower straight tubular trapezoidal member 100 is nested and the depth of the upper tubular tubular trapezoidal member is gradually increased. The distal end portion 101 of the lower straight tubular trapezoidal member 100 is inserted into the base end portion 100 of the 100 to the design dimension, so that they are mechanically connected so as to be evenly fitted in the peripheral direction and become linear.

  That is, the traction operation by the traction machine 30 is sequentially repeated every three locations around the straight tubular trapezoidal member 100, so that the base end portion 102 of the upper straight tubular trapezoidal member 100 becomes the distal end of the lower straight tubular trapezoidal member 100. The portion 101 can be gradually entered with a uniform dimension in the circumferential direction, and the straight tubular trapezoidal member 100 can be linearly fitted and joined together. Here, a case where one worker sequentially operates the traction machines 30 at three locations around the straight tubular trapezoidal member 100 will be described. You can also.

  Next, the base end portion 102 of the lower straight tubular trapezoidal member 100, the lower hook wire 31 of the traction machine 30, and the base plate member 200 are embedded together to install and fix the foundation of the panther mast. Here, in this embodiment, the base plate member 200 and the base end portion 102 of the straight tubular trapezoidal member 100 are embedded and fixed, and the top straight portion 101 of the lower straight tubular trapezoidal member 100 is connected to the upper straight portion. An assembly process of setting the traction machine 30 with the base end portion 102 of the tubular trapezoidal member 100 covered, and a direction in which the hook 10 hooked on the distal end portion 101 of the upper straight tubular trapezoidal member 100 is brought close to the base plate member 200. However, the present invention is not limited to this, and the base plate member 200 and the straight tubular trapezoidal member in which the hook 31a of the traction machine 30 is hooked on the U-shaped member 21. After performing the installation process of embedding and fixing the proximal end portion 102 of 100, the distal end portion 101 of the straight tubular trapezoidal member 100 is covered with the proximal end portion 102 of the next straight tubular trapezoidal member 100, and An assembly process for hooking the hook 10 to the tip 101 of the trapezoidal trapezoidal member 100 is performed, and then a pulling process for causing the hook 10 hooked to the tip 101 of the upper straight tubular trapezoidal member 100 to approach the baseplate member 200 is performed. Needless to say.

  Next, the restriction on the reverse rotation of the rotary drum 36 of the traction machine 30 is released, so that the distance between the hooks 31a is shortened (to pull the hook 10), and the traction wire 35 is rewound to rewind the upper side. The hook 10 hooked on the tip 101 of the straight tubular trapezoidal member 100 is removed. Thereafter, similarly, the base end portion 102 of the next straight tubular trapezoidal member 100 is stacked and combined so as to cover the distal end portion 101 of the upper straight tubular trapezoidal member 100, and then the upper straight portion after the combination is combined. The hooks 10 at the tips of the three wires 35 and 31 of the traction machine 30 are hooked on the opening end of the distal end portion 101 of the tubular trapezoidal member 100 at equal intervals, and the three hooks 10 are attached to each traction machine 30. By sequentially repeating the operation of pulling in the direction of approaching the three U-shaped members 21 of the base plate member 200, the lower straight tubular trapezoidal member 100 is inserted into the base end portion 102 of the upper straight tubular trapezoidal member 100. The front end portion 101 is made to enter the design dimension so as to be linearly inserted and connected and joined.

  At this time, the hook 10 to be hooked on the opening end portion of the tip portion 101 of the upper straight tubular trapezoidal member 100 is such that the inner surface of the wide plate-like member 13 of the hook-shaped portion 11 is the inner surface and end face of the opening end portion of the tip portion 101. Further, it is possible to transmit the traction force by the traction machine 30 while facing the outer surface, and avoid the deformation of the opening end portion of the tip portion 101 due to the traction force of a rod-like member such as the hook 31a contacting with a small area. can do. For this reason, without deforming the distal end portion 101 of the straight tubular trapezoidal member 100, the distal end portion 101 can be fitted and joined to the base end portion 102 so as to obtain the mechanical strength as designed. The hook wire 31 that hooks and connects the hook 31a to the ring member 14 of the hook 10 is long because the hook 10 is hooked to the opening end of the tip 101 of the straight tubular trapezoidal member 100 that gradually increases in this way. Alternatively, a plurality of types of lengths are prepared, and conversely, the hook wire 31 for hooking the hook 31a to the U-shaped member 21 of the base plate member 200 needs to operate the traction machine main body 32 at hand. For that reason, it is sufficient to prepare a thing of that length.

  In this way, the operation of fitting and connecting the distal end portion 101 of the lower straight tubular trapezoidal member 100 to the design dimension into the base end portion 102 of the upper straight tubular trapezoidal member 100 becomes a necessary height. After assembling to a linear panzer mast, the traction wire 35 wound up so as to shorten the distance between the hooks 31a by releasing the restriction of the reverse rotation of the rotary drum 36 of the traction machine 30 is rewound. The hook 10 hooked on the open end of the tip 101 of the upper straight tubular trapezoidal member 100 is removed and recovered, and the hook wire 31 and the traction machine main body 32 hooked on the hook 10 are recovered, while the base plate The hook wire 31 that hooks the hook 31a on the U-shaped member 21 of the member 200 is buried as it is so that it does not get in the way (perform the cleaning process). Complete of Kenbashira work.

  As described above, in the present embodiment, it is possible to fit the distal end portion 101 and the proximal end portion 102 of the straight tubular trapezoidal member 100 with a uniform desired depth in the circumferential direction only by using the hook 10 and the traction machine 30. It can be easily assembled into a panther mast with mechanical strength as designed. Therefore, it is possible to construct a panzer mast in which the assembly shape does not change due to the load of an article attached after the pillar.

  Although one embodiment of the present invention has been described so far, it is needless to say that the present invention is not limited to the above-described embodiment, and may be implemented in various forms within the scope of the technical idea. For example, the case where the panther mast is constructed by assembling the straight tubular frustoconical straight tubular trapezoidal member 100 will be described as an example, but it can also be used when combining the ends of straight tubular trapezoidal members such as a pyramid trapezoid. In this case, four hooks 10 and four sets of traction machines 30 may be used.
