Has disclosed a bird damage prevention tool for steel towers that can safely walk on a steel tower while removing the string-like body by hand, and that reduces the danger even if the string-like body accidentally falls. .

  Further, in Patent Document 2 below, a rain receiving angle is sandwiched and fixed between a U bracket and an I bracket, and an L-shaped support plate is fixed to a bolt of the U bracket with a nut. By supporting a pipe with a tape that radiates freely with a bearing on it, the crow suddenly rotates at the moment it stops being drawn by the shining tape, causing the crow to become unstable and cause fears, so that it will not approach afterwards A bird damage prevention apparatus is disclosed.

In addition, in the following patent document 3, the applicant of the present invention is an existing bolt that is made of an arsenic alloy containing about 5 to 15% by weight of arsenic that birds repel, and that fixes a structural material constituting the structure. The structure is simple and low-cost by screwing an arsenic alloy metal for bird harm prevention, which has a nut shape with a cylindrical groove with a female thread that can be screwed into, into the tip of the existing bolt. The present invention proposes an arsenic alloy metal for bird damage prevention that can be attached, is extremely simple to install, and hardly obstructs the work of the worker on the structure.
