Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to a fence for preventing birds such as pigeons from building nests.

(Prior art) Birds such as pigeons like to build their nests on the flat parts of H-shaped steel members of highway elevated bridge girders and guard bridge girders, and on the eaves of structures such as buildings. Contamination with excrement and urine seriously impairs environmental hygiene.

One way to prevent birds from building nests is to make sharp, chevron-shaped cuts of approximately 5 mm at equal intervals in a steel plate, and then to raise the cuts and place them at predetermined locations. This steel plate has sharp protrusions arranged to make it difficult for birds to get a foothold, thereby preventing birds from settling there. Birds deal with this by laying straw or leaves between the protrusions to make them flat, so steel plates like this, which make it difficult for birds to get a foothold, are not effective as a means to prevent nest building. I can't perform. Moreover, it is easy to injure the builder during construction. Furthermore, resin nets or wire meshes are placed on the front surfaces of H-shaped steel materials to prevent birds from building nests. but,
Pigeons and other insects can enter the interior through small gaps in the attachment parts of resin nets and wire mesh. Once they invade, they cannot escape and eventually starve to death. The carcasses decompose, causing discomfort and being unhygienic. The aesthetic appearance is also impaired. Furthermore, this method results in extremely high construction costs.

Therefore, recently, bird repellents (for example, for soil pigeons, Aranik (trade name, manufactured by Tanabe Seiyaku Co., Ltd.)) are increasingly being used instead. Although such drugs are applied to predetermined areas using a spray gun, they have the fatal drawback of losing their efficacy within a short period of time due to rain or sunlight. It also scatters into the air during application and contaminates the air.
It is eagerly awaited that a device that is harmless to the human body, easy, inexpensive, and semi-permanently capable of preventing birds from building nests is eagerly awaited.

(Purpose of the invention) The purpose of the invention is to provide a fence that is harmless to the human body, easy and inexpensive, and can semi-permanently prevent birds from building nests. Other purposes of this invention are:
To provide a fence for preventing birds from building nests, which is easily manufactured and constructed.

(Structure of the invention) The fence of the invention consists of a plurality of strips erected at regular intervals in order to make it impossible for birds to land on the ground, and a fence that detours behind the strips and adjoins each other. and a member for connecting the strips, thereby achieving the above object.

The present invention will be described below with reference to embodiments.

(Example) As shown in FIGS. 1, 2, and 3, the fence 1 of the present invention includes a plurality of vertical strips 11 and a member for connecting the strips 11. 12. The spacing between the strips 11 is set to be sufficiently narrower than the body of the target bird. In the case of earth pigeons, the spacing is 3-5 mm. Connecting member 1
2 connects adjacent strips 11, and
A predetermined interval is always maintained. Therefore, birds will not widen the spacing between the strips 11 and enter inside. The connecting member 12 is formed in a detour behind the strips 11, for example, in a substantially U-shape or a substantially V-shape, and connects adjacent strips 11. Therefore, birds cannot even perch on the connecting member 12.

The strip 11 and the connecting member 12 are made of vinyl chloride resin, vinyl acetate resin, polystyrene, or ABS.
Thermoplastic synthetic resins such as resin, acrylic resin, polyethylene, polypropylene, fluororesin, polyamide resin, acetal resin, polycarbonate, phenolic resin, urea resin, melamine resin, unsaturated polyester resin, epoxy resin, diallyl phthalate resin, polyurethane It is obtained by integrally molding resin, thermosetting synthetic resin such as silicone resin, etc. These synthetic resins can be combined with other synthetic resins, or appropriately mixed with UV absorbers, antioxidants, colorants, fillers, etc. to improve moldability, durability, weather resistance, design, and impact resistance. It is also possible to add gender etc. as necessary. When the strip 11 and the connecting member 12 are made of synthetic resin in this manner, they can be easily cut to desired dimensions on site depending on the installation location.

The fence 1 is connected to a fixed part 2 via a fixed member 3, for example, an H
It is attached to a flange portion 21 of a shaped steel material, a channel steel material, or the like. The fence 1 is arranged so as to be located on the same plane as the flange end surface 20 of the fixed part 2. Therefore, the bird has the flange plane 2 of the fixed part 2.
2. It is impossible to reach the top and it becomes impossible to build a nest. The fixing member 3 has a fixing area formed into an L-shape, for example, in order to firmly fix and support the fence 1 made of a bar-shaped strip 11 in a more stable state. The end of the strip 11 which is directly fixed to the fixing member 3 also has an L-shape accordingly. All ends of the strip 11 may be L-shaped. The L-shape of the end of the strip is composed of a strip main body 110 and an extension portion 111 extending behind the strip main body 110 in a substantially perpendicular direction. strip 11
can be reliably supported and fixed to the fixing member 3 by the L-shaped end. The fence 1 may be supported and fixed to the fixing member 3 by keeping the strip 11 in a bar shape without making the ends of the strip 11 L-shaped. Since the fence 1 does not have any particular directionality, it can also be installed upside down depending on the situation at the construction site. At this time, the fixing member 3 is attached to the upper flange 2 of the fixing part 2.
It is fixed at 3. When the lower end 112 of the fence 1 is set at a distance of approximately 1 to 2 cm from the flange surface 22 of the fixed part 2, a scaffold for high-altitude work is attached using this distance, and the fence 1 is attached and
Easy to remove. The fixing member 3 is made of a material having excellent weather resistance, heat resistance, corrosion resistance, or impact resistance, such as stainless steel, steel whose surface is coated with synthetic resin or chrome plating, or synthetic resin.

The fence 1 connects the strip 11 with a connecting member 12.
If you divide it into small units in advance via a
Convenient for construction.

(Effects of the invention) Since the fence of the present invention has a structure that makes it impossible for birds to land on it, it is possible to semi-permanently prevent birds from building nests. Furthermore, since the structure is extremely simple, it is easy to manufacture and install, and can be removed and reinstalled when painting or the like. It's also cheap. Furthermore, it is harmless to the human body.
