Description
この発明は、台棒を用いた鉄塔の組立又は解体工法等に関するもので、更に詳しく述べると、鉄塔の中間で台棒の振れ止め用支線を支持する中間支線支持棒を備えた、台棒による組立又は解体工法及びその装置に関するものである。 The present invention relates to an assembling or dismantling method of a steel tower using a pedestal. More specifically, the present invention relates to a pedestal provided with an intermediate branch line support bar for supporting a supporting line for stabilizing the pedestal in the middle of the steel tower. The present invention relates to an assembling or dismantling method and an apparatus therefor.
５００ｋＶ安曇幹線等に代表される烏帽子型鉄塔の解体工法は、通常の四角鉄塔とは、形状が大きく異なること、山間地（一部、国立公園、県立公園内）を通過している施工条件では、従来工法での撤去が難しい現状にある。 The dismantling method of the Hata type steel tower represented by the 500kV Azumi main line, etc., is different in shape from the normal square steel tower, and under construction conditions that pass through mountainous areas (partly in national parks and prefectural parks) The existing method is difficult to remove.
安曇幹線建設時の組立工法は、仮鉄塔とワイヤを利用した「仮鉄柱方式」と「台棒方式」を併用しており、台棒による工法を行うためには台棒頂部から地面まで支線を３方向以上設置しなければならないことから、鉄塔周囲の広範囲な伐採が必要となる。 The construction method for the construction of the Azumi trunk line uses both the “temporary iron pole method” and the “base rod method” that use a temporary tower and wires. In order to carry out the construction method using the base rod, a branch line is provided from the top of the base rod to the ground. Since it must be installed in three or more directions, extensive logging around the steel tower is required.
また、建設当時（昭和３７年頃）の状況は、上記工法で危険な思いを何度もしたなど、安全面では課題の多い工法であることが想定される。 In addition, the situation at the time of construction (around 1953) is expected to be a construction method with many problems in terms of safety, such as having repeatedly thought about danger with the above construction method.
近年の鉄塔工事において烏帽子型鉄塔を解体した実績では、安全面を考慮してクライミングクレーンなどの大型機械で撤去を行っている。しかしながら、クレーンの物輸、設置などに多くの労力を要している。 In the recent construction of steel towers, dismantling the cocoon-cap type steel tower, we removed it with a large machine such as a climbing crane in consideration of safety. However, much labor is required for the transportation and installation of cranes.
一方、台棒工法による鉄塔組立・解体は、小型工具のため、物輸・設置等に要する労力は少ない標準工法である。その大きな要因は構造が簡単で重量が軽い点にあり、山間地での適用に優れている。台棒工法とは「デリック構造規格」においてジンポールデリックと呼ばれ、傾斜させたマスト（台棒）を３本以上のガイドロープ（起伏ワイヤを含む支線）で支える構造であり、図５に示すように台棒１と３本の支線２ａ、２ｂで構成されるものをいう。３本の支線２ａ、２ｂは、１本が起伏ワイヤを兼用した起伏ワイヤ用支線２ａであり、この支線２ａの長さを調整することにより台棒１の傾きを調整するものである。他の２本が振れ止め用支線２ｂである。また、前記台棒１の先端部には滑車を介して、下端にフックを有する吊り下げワイヤ３が掛けられ、当該吊り下げワイヤ３の一端は地上のウインチへ繋がっている。 On the other hand, steel tower assembly and dismantling by the pedestal method is a standard method because it is a small tool and requires little labor for goods transportation and installation. The major factor is its simple structure and light weight, which makes it excellent for application in mountainous areas. The pedestrian construction method is called ginpole derrick in the “derrick structure standard” and is a structure that supports an inclined mast (pedestal) with three or more guide ropes (branches including undulating wires), as shown in FIG. In this way, it is composed of a base bar 1 and three branch lines 2a, 2b. The three branch lines 2a and 2b are undulation wire branch lines 2a that also serve as undulation wires, and the inclination of the support bar 1 is adjusted by adjusting the length of the branch line 2a. The other two are the steadying branch lines 2b. A suspension wire 3 having a hook at the lower end is hung on the tip of the base rod 1 via a pulley, and one end of the suspension wire 3 is connected to a ground winch.
この様に、支線は３本とることになっているが、適用に当たっては以下の課題が生じる。起伏ワイヤ用支線２ａを除き、他の２本は振れ止め防止用支線２ｂとなり、当該振れ止め用支線２ｂの一端は台棒１の先端部に固定し、他端を地上に設置したアンカーに固定することが必要である。そして、この支線２ｂは、一定の張力を出すため、地上で繰り出したり、巻き上げたり等の操作をするものであり、支線取付け角度を確保するため、図６に示すように、地上の支線アンカー設置位置を鉄塔敷地より大きく離す必要がある。この場合、支線設置のための工事用敷地の拡大と山間地では樹木伐採が広範囲に及ぶ。 In this way, three branch lines are supposed to be used, but the following problems arise in application. Except for the undulating wire branch line 2a, the other two are anti-sway branch lines 2b. One end of the anti-sway branch line 2b is fixed to the tip of the base bar 1 and the other end is fixed to an anchor installed on the ground. It is necessary to. This branch line 2b is used for operations such as drawing out and winding up on the ground in order to exert a constant tension. In order to secure a branch line mounting angle, as shown in FIG. The location needs to be far away from the tower site. In this case, expansion of the construction site for branch line installation and logging of trees in mountainous areas are extensive.
また、鉄塔が尾根に立地している場合などは、図７の（Ａ）図に示すように、支線の下端が谷底方向になるため、地上に固定することが出来ない。また、鉄塔が片斜面に立地している場合、図７の（Ｂ）図に示すように、支線の下端が斜面に当たり、これをアンカーに止めても支線が機能しない。この様に山間地では、適用が困難な場合が多く、山間地を始め、市街地など支線用地が確保できない場合は、台棒工法の適用が見送られるケースが多い。 In addition, when the steel tower is located on the ridge, as shown in FIG. 7A, the lower end of the branch line is in the valley bottom direction, it cannot be fixed on the ground. Moreover, when the steel tower is located on one slope, as shown in FIG. 7B, the lower end of the branch line hits the slope, and the branch line does not function even if it is fixed to the anchor. In this way, in mountainous areas, application is often difficult, and when a branch line site such as a mountainous area or a city area cannot be secured, application of the bar method is often missed.
そこで、特許文献１に示すように、先端側に滑車が取り付けられるとともに、基端部が組立て・解体を行う鉄塔に取り付けられており、かつ、鉄塔に接続された支線によって鉄塔に支持されている台棒を備えている、鉄塔の組立て・解体装置が開発された。これにより容易かつ安価に鉄塔の組立て・解体を行うことができると共に従来のようなに支線の他端を地上に固定するための用地を必要としない。 Therefore, as shown in Patent Document 1, a pulley is attached to the distal end side, and a base end is attached to a steel tower that is assembled and disassembled, and is supported by the steel tower by a branch line connected to the steel tower. An assembling and dismantling device for steel towers with a pole was developed. As a result, the steel tower can be assembled and disassembled easily and inexpensively, and a site for fixing the other end of the branch line to the ground as in the prior art is not required.
しかしながら、この特許文献１のものは、２本の振れ止め用支線の台棒への取付け点と、支線の他端の鉄塔への取付け点までの距離が短くなるため、支線位置と、鉄塔への取付け点の反力が大きくなり、これらの力に耐えられないおそれがある。また、台棒の中間箇所で支線の先端をとり、他端を鉄塔に固定する場合は、支線をとる位置で曲げモーメントが大きく発生する。また、支線の張力の管理や操作を鉄塔上でしなければならないため、管理や操作がしにくいといった欠点がある。 However, since the distance between the attachment point of the two steadying branch lines to the pole and the attachment point of the other end of the branch line to the tower is shortened, the position of the branch line and the tower The reaction force at the attachment point of the head becomes large, and there is a possibility that these forces cannot be endured. Further, when the tip of the branch line is taken at the middle portion of the bar and the other end is fixed to the steel tower, a bending moment is greatly generated at the position where the branch line is taken. In addition, since the tension and management of the branch line must be performed on the steel tower, there is a drawback that it is difficult to manage and operate.
そこで、この発明はこれらの従来技術を改善すべく、台棒工法において支線の基端を地上に固定するための用地を大きく確保する必要がないとともに、従来の台棒と変わらず、３本の支線により台棒が確実に支持され、支線の張力管理も地上で行える、中間支線支持棒を備えた台棒による鉄塔組立・解体工法及び装置を提供するものである。 Therefore, in order to improve these conventional techniques, the present invention does not require a large site for fixing the base end of the branch line to the ground in the base bar method, and is not different from the conventional base bar. It is an object of the present invention to provide a steel tower assembling / disassembling method and apparatus using a base bar provided with an intermediate branch line support bar, in which the base bar is securely supported by the branch line and the tension of the branch line can be managed on the ground.
請求項１の発明は、組立又は解体中の鉄塔に台棒の基端部を支持させ、起伏ワイヤ用支線の先端を台棒の先端部に、他端を鉄塔箇所に支持させ、２本の各振れ止め用支線の一端を台棒の先端部に固定し、他端を当該台棒の左右側に伸ばした台棒工法において、前記台棒の基端部の支持箇所より下方の鉄塔箇所に、中間支線支持棒を略水平に固定し、当該中間支線支持棒の両端を前記台棒の略左右側位置の鉄塔外側に突出させ、前記各振れ止め用支線の他端を一旦前記中間支線支持棒の先端に摺動自在に係止させ、さらに、当該支線の他端を伸ばして鉄塔の基礎部に夫々固定し、前記台棒に設けた吊り下げワイヤにより鉄塔部材を昇降させる、台棒による鉄塔の組立・解体工法とした。 In the invention of claim 1, the base end of the pedestal is supported on the steel tower being assembled or dismantled, the tip of the branch wire for undulation wire is supported on the tip of the pedestal, and the other end is supported on the tower position.

また、請求項４の発明は、請求項２又は３の発明において、各振れ止め用支線の他端を中間支線支持棒の先端で摺動自在に支持させる手段が、中間支線支持棒の両端に設けた四面ローラである、台棒による鉄塔の組立・解体装置とした。 According to a fourth aspect of the present invention, in the second or third aspect of the present invention, means for slidably supporting the other end of each steadying branch line at the tip of the intermediate branch line support bar is provided at both ends of the intermediate branch line support bar. The steel tower assembly and dismantling device is a four-sided roller that is provided.
請求項１〜４の発明によれば、従来、台棒の２本の振れ止め用支線の下端（他端）を、鉄塔敷地から大きく離れた地上位置に設けていたが、この様に鉄塔敷地から大きく離れた地上位置に設ける必要がない。従って、従来、台棒工法を適用できなかった山間地や市街地においても適用でき、台棒工法の汎用性が広がり、適用効果が大きい。 According to the inventions of claims 1 to 4, conventionally, the lower ends (the other ends) of the two steadying branch lines of the pedestal have been provided at a ground position far away from the tower site. There is no need to provide it at a ground position far away from the ground. Therefore, it can be applied to mountainous areas and urban areas where the pedestal method could not be applied conventionally, and the versatility of the pedestal method is widened and the application effect is great.
また、従来の台棒、ジンポールデリックと変わらず、振れ止め用支線は、台棒の先端部から地上部まで伸ばして固定するため、支線の台棒への取付け点と、支線の鉄塔の地上部への取付け点までの距離が長いため、地上部の取付け点の反力が大きくならない。また、地上部である鉄塔基礎部で、振れ止め用支線の張力管理や操作が行え、便利である。さらに、中間支線支持棒の長さを調整すれば、デリック構造規格で要求されている支線取付け角度を容易に確保することが出来る。 In addition, unlike the conventional pedestal and ginpole derrick, the steadying branch line extends from the tip of the pedestal to the ground and is fixed, so the attachment point of the branch line to the pedestal and the ground of the branch tower Since the distance to the mounting point on the part is long, the reaction force at the mounting point on the ground does not increase. In addition, it is convenient because the tension control and operation of the branch line for steadying can be performed at the base of the steel tower. Furthermore, if the length of the intermediate branch line support bar is adjusted, the branch line mounting angle required by the derrick structure standard can be easily secured.
また、請求項４の発明によれば、中間支線支持棒の両端各端に四面ローラを設けているため、２本の振れ止め用支線をそれぞれ四面ローラに通すことが出来、各振れ止め用支線は、当該四面ローラ内で摺動が極めて容易となり、地上で行う張力管理（巻取、送出）が容易、確実となる。 Further, according to the invention of claim 4, since the four-sided roller is provided at each end of the intermediate branch line support rod, the two steadying branch lines can be passed through the four-sided roller, respectively. Is extremely easy to slide in the four-sided roller, and tension management (winding and feeding) performed on the ground is easy and reliable.

Embodiment 1 of the present invention will be described below with reference to the drawings.
The base end of the bar 1 is supported on the left hinge portion h of the tip of the cocoon hat type steel tower T. And the front-end | tip of the branch wire 2a for undulation wires is locked to the front-end | tip part of the base bar 1, and a lower end is latched to the steel tower T between the front-end | tip part of a base bar 1, and a base end part, A winch etc. ( By adjusting the length by providing a not shown), the undulation state of the base bar 1 changes.
前記鉄塔Ｔのベント部ｂに中間支線支持棒４を略水平に固定する。その際、当該中間支線支持棒４の両端が、前記台棒１の左右方向に向け、ベント部ｂから外側にそれぞれ突出させるようにする。この中間支線支持棒４の両端には、図４に示すように、四面ローラ４ａがそれぞれ設けられている。なお、図１において、鉄塔Ｔの両側のベント部ｂに中間支線支持棒４をそれぞれ設けているが、一方の中間支線支持棒４は、他のヒンジ部ｈに台棒１を取り付けた場合に使用するものである。 The intermediate branch line support rod 4 is fixed substantially horizontally to the vent portion b of the steel tower T. At that time, both ends of the intermediate branch line support rod 4 are protruded outward from the vent portion b in the left-right direction of the base rod 1. As shown in FIG. 4, four-sided rollers 4 a are respectively provided at both ends of the intermediate branch line support rod 4. In FIG. 1, the intermediate branch line support rods 4 are provided at the vent portions b on both sides of the steel tower T, but one intermediate branch line support rod 4 is provided when the base rod 1 is attached to the other hinge portion h. It is what you use.
そして、前記台棒１の２本の振れ止め用支線２ｂは、台棒１の先端部に一端を固定し、他端は、前記中間支線支持棒４の両端各端の四面ローラ４ａに通して、鉄塔Ｔの基礎部５に固定する。この基礎部５には、鉄塔Ｔの基礎付近の脚部や基礎を含む。そして、２本の振れ止め用支線２ｂの張力については、基礎部５において、当該支線２ｂを巻き取ったり、繰り出したりして調整するものである。 The two steadying support lines 2b of the base bar 1 have one end fixed to the tip of the base bar 1 and the other end passed through four-sided rollers 4a at both ends of the intermediate branch line support bar 4. , Fixed to the foundation 5 of the steel tower T.
