【発明の詳細な説明】 ［産業上の利用分野］ 本発明は降雪地帯に建設される鉄塔の脚部の補強部材を
雪害から保護するための装置に関するものである。TECHNICAL FIELD The present invention relates to a device for protecting a reinforcing member of a leg portion of a steel tower constructed in a snowfall area from snow damage.
［従来技術とその問題点］ 降雪地帯に建設される鉄塔の脚部の補強部材を雪害から
保護する方策の１つとして、一端側を地中に埋設して集
熱部としたヒートパイプの他端側を雪害から保護すべき
補強部材に添わせ、地中の熱を利用して周囲の雪の一部
を溶かすことが提案されている。[Prior art and its problems] As one of the measures to protect the reinforcing member of the leg portion of the steel tower constructed in a snowfall area from snow damage, a heat pipe other than the heat pipe by burying one end side in the ground is used. It has been proposed that the end side be added to a reinforcing member to be protected from snow damage, and the heat in the ground is used to melt a part of the surrounding snow.
これらは何れも積雪の沈降力や移動圧に対して一方の成
分に有効なように、ある方向（通常真上）にヒートパイ
プの他端側（放熱部）を配置し、融雪により力の作用線
を不連続もしくは力線を生じさせないようにしたもので
ある。In each case, the other end of the heat pipe (heat dissipation part) is placed in a certain direction (usually directly above) so that it is effective for one of the components against the subsidence force and the moving pressure of snow, and the action of force by snow melting It is a line that does not cause discontinuity or lines of force.
従って、積雪の移動圧と沈降力の両方が作用する場合は
各々の方向に対して別々にヒートパイプを設置する必要
があり、不経済である。Therefore, when both the moving pressure of snow and the sinking force act, it is necessary to install heat pipes separately for each direction, which is uneconomical.
［発明の目的］ 本発明はこのような点に鑑み、少ない数のヒートパイプ
で補強部材に作用する積雪の移動圧や沈降力を低減する
ことのできる保護装置の提供を目的としてなされたもの
である。[Object of the Invention] In view of such a point, the present invention has been made for the purpose of providing a protective device capable of reducing the moving pressure and the sinking force of snow that acts on the reinforcing member with a small number of heat pipes. is there.
［発明の概要］ 本発明は、一端側を地中に埋設して集熱部としたヒート
パイプの他端側を、鉄塔の脚部の補強部材の周りにらせ
ん状に配置したことを特徴としている。[Summary of the Invention] The present invention is characterized in that the other end side of a heat pipe having one end side buried in the ground as a heat collecting part is arranged in a spiral shape around a reinforcing member of a leg part of a steel tower. There is.
［実施例］ 本発明を図面に示す実施例を参照して説明する。第１図
は送電線用鉄塔等の鉄塔脚部に適用した場合を示してい
る。[Examples] The present invention will be described with reference to the examples shown in the drawings. FIG. 1 shows a case where the present invention is applied to a steel tower leg portion of a transmission line steel tower or the like.
鉄塔脚部は、主柱１、補強材２、基礎３等からなってお
り、そこには一端側51を基礎３の近傍の土壌４中に所定
の長さ埋設して集熱部としたヒートパイプ５の他端側52
が斜めの補強材２の周囲にこれに添ってらせん状に配置
され、放熱部とされている。The tower leg portion is composed of a main pillar 1, a reinforcing member 2, a foundation 3, etc., and one end side 51 is embedded in the soil 4 near the foundation 3 for a predetermined length to form a heat collecting portion. The other end 52 of the pipe 5
Are arranged around the diagonal reinforcing member 2 in a spiral shape so as to serve as a heat radiating portion.
この場合、補強材２とヒートパイプの放熱部52との間に
は熱絶縁機能を有する取付治具６が適宜の間隔で介装さ
れ、地中の熱が補強材２を通して散逸しないようにされ
ている。In this case, mounting jigs 6 having a heat insulating function are interposed between the reinforcing material 2 and the heat radiating portion 52 of the heat pipe at an appropriate interval to prevent heat in the ground from being dissipated through the reinforcing material 2. ing.
通常、降雪期であっても地表から数メートルの深さの地

へ輸送され、そこで放熱される。従って、そのとき降雪
があって、鉄塔脚部の下方が積雪に覆われてもヒートパ
イプ５はその熱移送作用を継続するため、放熱部52の周

熱部52からの熱によって順次溶かされることになるた
め、雪の沈降ないし移動する方向へ拡大され、補強材２
やに加わる積雪の荷重を引続き軽減する。Normally, even in the snow season, the temperature in the ground at a depth of a few meters from the ground surface is around 10 ° C, so the heat pipe 5
If one end side 51 of the heat sink is buried as a heat collecting portion, the heat on the ground is enclosed by the temperature decrease on the surface side and the heat collecting portion 52
It rapidly evaporates and vaporizes the working fluid such as water, Freon ammonia, and methanol ammonia, which rapidly dissipates heat on the ground.
Is transported to where it is radiated. Therefore, even if there is snow at that time, the heat pipe 5 continues its heat transfer action even if the lower part of the steel tower leg portion is covered with snow, so that the snow around the heat radiating portion 52 is melted and the reinforcement provided by this is melted. A cylindrical snow cavity is formed around the material 2. When the snow sinks or moves, the snow voids are successively melted by the heat from the heat radiating portion 52 when the snow falls or moves, so the snow cavities are expanded in the direction in which the snow sinks or moves, and the reinforcing member 2
Continue to reduce the load of snow on the snow.
この場合、ヒートパイプ５の放熱部52が補強材２やの周
りにらせん状に配置され、全周を保護するようになって
いるため、いずれの方向に対しても１本のヒートパイプ
５が有効に作用し、地中の熱を有効に活用することがで
きる。In this case, since the heat dissipating portion 52 of the heat pipe 5 is spirally arranged around the reinforcing material 2 and protects the entire circumference, one heat pipe 5 is provided in any direction. It works effectively and can effectively utilize the heat in the ground.
放熱部52をらせん状に配置した場合、取付治具６の一部
が破損しても当初の布設状態を保つことが可能で、融雪
効果が補償されることは言うまでもない。If the heat radiating portion 52 is arranged in a spiral shape, it is needless to say that even if a part of the mounting jig 6 is damaged, the initial installation state can be maintained and the snow melting effect is compensated.
これらは周囲に積雪がある場合であるが、ヒートパイプ
５の他端側52は積雪のない場合にも有効に作用する。す
なわち、補強材２は強風により振動して損傷する場合が
あるが、それらにヒートパイプ５をらせん状に配置して
おくことにより補強材２の表面の風が乱されるため防振
効果が現れ、補強材２の寿命を延ばすことができる。These are cases where there is snow in the surroundings, but the other end side 52 of the heat pipe 5 works effectively even when there is no snow. That is, although the reinforcing material 2 may be vibrated and damaged by a strong wind, the wind on the surface of the reinforcing material 2 is disturbed by arranging the heat pipes 5 in a spiral shape on them, so that a vibration damping effect appears. The life of the reinforcing material 2 can be extended.
尚、放熱部52は、予めらせん状に成形されたものを配置
してもよいし、布設時成形しながら配置してもよい。The heat radiating portion 52 may be arranged in a spiral shape in advance, or may be arranged while being formed during the laying.
［発明の効果］ 以上から明らかなように、本発明はヒートパイプの放熱

あるから、前記部材に作用する積雪の沈降力や移動圧を
少ない数のヒートパイプで低減することができ、経済的
であるという利点がある。[Advantages of the Invention] As is clear from the above, since the present invention arranges the heat radiating portion of the heat pipe in a spiral shape around the member to be protected, the sinking force of snow and the moving pressure acting on the member are effective. Can be reduced with a small number of heat pipes, and there is an advantage that it is economical.
