上記のような鉄塔用アンテナ取付金具においては、既設の鉄塔を構成する山形鋼材に穴あけ加工や溶接などの施工手段を要することなく、アンテナ取付用の支持金具を取り付けることが可能である。
しかしながら、上記の鉄塔用アンテナ取付金具は、外側挟持部材と内側挟持部材とで山形鋼材をその内外側面から挟み、外側挟持部材と内側挟持部材の相対向する両端部をボルト・ナットにより締め付けることでアンテナ取付用の支持金具を山形鋼材に保持する方式であるため、外側挟持部材と内側挟持部材の相対向する両端部が互いに接近する方向に弾性変形されるまでボルト・ナットを締め付けないと、外側挟持部材と内側挟持部材による山形鋼材への挟持力を確保できない。その結果、外側挟持部材と内側挟持部材による山形鋼材への締め付け力は山形鋼材の両辺の端縁部分に集中し、この両辺の端縁部分を除く山形鋼材の内外側面と外側挟持部材及び内側挟持部材との接触圧は両辺の端縁部分より大幅に低下する。このため、外側挟持部材及び内側挟持部材の経年変化によりその弾性力が低下してくると、山形鋼材の内外側面と外側挟持部材及び内側挟持部材との摩擦が低下しアンテナを安定して鉄塔に支持することができなくなり、アンテナの自重や強風などによりアンテナの位置がずれてしまうというおそれがある。
In tower antenna mounting bracket as described above, without requiring facilities Engineering means such as drilling or welding Yamagata steel constituting the existing tower, it is possible to attach the supporting brackets for the antenna installation.
However, the above-mentioned antenna mounting bracket for a steel tower is formed by sandwiching a chevron steel material from the inner and outer surfaces between the outer sandwiching member and the inner sandwiching member, and tightening opposite ends of the outer sandwiching member and the inner sandwiching member with bolts and nuts. Since the antenna mounting support bracket is held on the angle steel, the bolts and nuts must be tightened until the opposing ends of the outer and inner clamping members are elastically deformed in a direction approaching each other. The clamping force to the angle steel material by the clamping member and the inner clamping member cannot be secured. As a result, the clamping force to the angle steel by the outer clamping member and the inner clamping member concentrates on the edge portions of both sides of the angle steel material, and the inner and outer surfaces of the angle steel material, the outer clamping member and the inner clamping except for the edge portions of both sides. The contact pressure with the member is significantly lower than the edge portions on both sides. For this reason, when the elastic force of the outer clamping member and the inner clamping member decreases due to aging, the friction between the inner and outer surfaces of the angle steel material and the outer clamping member and the inner clamping member is reduced, and the antenna is stably added to the tower. There is a possibility that the antenna cannot be supported and the position of the antenna may be shifted due to its own weight or strong wind.
