Description

  The present invention relates to a bird damage prevention tool and apparatus and method for preventing damage caused by bird perches in a building, fouling by nests, droppings, and the like. In particular, the present invention relates to a bird injury prevention wire extension tool, a bird injury prevention device, and a bird injury prevention method for preventing a damage caused by suspending flight of birds or nesting behavior by stretching a wire rod.

  Traditionally, in buildings, for example, birds such as pigeons, sparrows, and phoenixes have come to rest or nesting, and only damage the building due to damage, for example, in the recesses and flanges of horizontal steel frames, on the verandas and parapets, etc. In addition, the damage caused by the fouling of people and vehicles passing through the lower part, odor, germs, etc., and the damage cannot be overlooked, and a solution is demanded as soon as possible. For this reason, various methods have already been proposed as measures against bird damage. For example, a method for preventing the arrival of birds by installing a plurality of wire rods proposed in Patent Literature 1, Patent Literature 2, etc. with a predetermined interval or by stretching a net, or a steel frame proposed in Patent Literature 3 etc. A method of inhibiting perch behavior by attaching a member using needle-like projections to the upper surface of a horizontal member or attaching a spiral elastic repellent device such as a linear member proposed in Patent Document 4 Etc. have been proposed.

  However, as a bird damage prevention measure, there are also steel frame parts and concrete parts in the place where bird damage is avoided in buildings, and it must deal with various constraints such as shape and dimensions, and has a wide range of condition compatibility. In addition to being demanded, there is a demand for a simpler, easier construction, and higher bird damage prevention effect. For this reason, in the method of installing a plurality of wires at predetermined intervals, in the example of Patent Document 1, only the concrete part of the veranda is supported, the steel part is not supported and the concrete part is damaged, and in the example of Patent Document 2, The object of bird damage prevention is only to cope with the recesses of the lip groove shape steel, but not to other H-shaped steel portions. In addition, in the case of a method of extending a net, it is necessary to cover a wide area all at once, and the damage caused by nesting, droppings, etc. becomes more serious if there is a bird intrusion part in some part There is fear and aesthetics are not preferable. Then, the perch action is performed by a method such as an example of Patent Document 3 using a needle-like projection member on the upper surface of a steel horizontal member or an example of Patent Document 4 in which a spiral elastic repellent device such as a linear member is attached. In the case of the method of hindering, the place where it can be dealt with is limited, dust is likely to accumulate, and cleaning is not easy, and there is a risk of causing secondary damage due to falling or re-scattering of a lump of dust. In this way, in reality, there are no proposals that can be sufficiently answered as measures for preventing bird damage in buildings that require as wide a range of conditions as possible.

For this reason, as a measure to prevent bird damage to buildings that must comply with various constraint conditions such as shape and dimensions, it has a wide range of conditions support as much as possible, is highly effective in preventing bird damage, and drops of dust etc. There is little fear of secondary damage due to re-scattering, etc., proposals for bird damage prevention measures that are easy to construct and have few aesthetic problems are desired.
