TOWER-CLIMBING PREVENTION DEVICE
PROBLEM TO BE SOLVED: To provide a tower-climbing prevention device which makes it possible to bring a mounting member into sufficiently close contact with a steel tower member to be fixed with reliability even if the mounting member of the tower-climbing prevention device contains a certain degree of error with respect to the cross-sectional shape and dimension of a steel tower member.SOLUTION: A steel tower member 2 is sandwiched between a pair of mounting members 3, 3, and a filler 4a for forming a gap between mounting member end parts 3a, 3a is provided at least one location of a coupling section for coupling the mounting members 3, 3 to each other. The section of the pair of mounting member end parts 3a, 3a (fastening section d) located between the filler 4a and the surface of the steel tower member 2 is set to be a gap, and at least one fastening bolt 5 is provided for penetrating the pair of mounting member end parts 3a, 3a in this section. Furthermore, a contact piece 8 is provided at a contacting position of the pair of mounting member end parts 3a, 3a and the surface of the steel tower member 2, or the contact piece 8 may be formed as a part of the pair of mounting member end parts 3a, 3a. The dimension between both the tip ends of the contact piece 8 is made longer than the width of the pair of mounting members 3a, 3a.SELECTED DRAWING: Figure 4
【課題】昇塔防止装置の装着部材が、鉄塔部材の断面形状と寸法に対してある程度の誤差を含んでいても、装着時に、装着部材が鉄塔部材に十分に密着し、確実に固定できる昇塔防止装置を提供する。【解決手段】鉄塔部材２を一対の装着部材３、３で挟み込み、装着部材３、３同士を連結する連結箇所の少なくとも１箇所に、装着部材端部３ａ、３ａ同士の間に隙間を形成するためのフィラー４ａを設ける。フィラー４ａと鉄塔部材２の表面との間に位置する一対の装着部材端部３ａ、３ａの区間（締付け区間ｄ）は空隙とし、この区間の一対の装着部材端部３ａ、３ａを貫通する締付けボルト５を、少なくとも１本以上設ける。また、一対の装着部材端部３ａ、３ａと鉄塔部材２表面との接触位置に接触片８を取付け、もしくは一対の装着部材端部３ａ、３ａの一部として接触片８を形成してもよい。その接触片８の両先端間寸法は一対の装着部材３ａ、３ａの幅よりも長くする。【選択図】図４
