Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a windproof / snowproof plate which is installed between columns to constitute a windproof / snowproof fence.
The present invention relates to a windproof / snowproof board that uses a resin such as polycarbonate to improve the transparency and facilitates assembly and vibration control.

[0002]

2. Description of the Related Art In winter snowfall areas, snow fences are provided on the side of roads as a measure against traffic obstacles. The snow fences are known as a blow-off type and a blow-off type, and the blow-off type snow fence is constructed by arranging a plurality of snow plates at intervals vertically between columns. A keystone plate such as a zinc-iron plate is conventionally used for the snow-proof fence because such a snow-proof fence is required to have a strength capable of withstanding wind and snow at a wind speed of about 30 to 50 m / sec.

[0003] However, since the snowboard made of a keystone plate obstructs the view of the surroundings, it is not preferable in terms of landscape and traffic safety, and furthermore, it blocks sunlight to inhibit snowmelt and growth of the surrounding crops. There is a disadvantage that. Furthermore, from the viewpoint of traffic safety, measures to remove the snow protection plate in the spring and install it in the winter are adopted, but the keystone plate made of zinc iron plate is heavy, and the burden on workers when removing and installing is heavy. There was also.

Therefore, in recent years, various snow protection fences have been developed in which a snow protection board is made of a transparent resin, for example, a polycarbonate resin, and has a reduced weight and improved transparency. Even the applicant of the present invention, as a transparent resin snow protection plate used for this type of snow fence, a frame member is fastened to both sides of a transparent resin plate having a flat or wavy cross section with bolts or the like, A reinforcing member is provided between the reinforcing members, and the reinforcing member is fastened to the transparent resin plate with bolts or the like to reinforce the transparent resin plate (Japanese Patent Application Nos. 7-346305 and 8-1).
No. 37401).

[0005] The snowboard according to the above-mentioned prior application is
A long hole is formed in a transparent resin plate or the like, and a frame member or a reinforcing member is fastened with a bolt or the like penetrating the long hole, and a rubber packing is interposed between the transparent resin plate and the frame member or the reinforcing member. In addition, while allowing thermal shrinkage of the transparent resin plate due to temperature changes during the day and night, vibrations caused by wind and the like are buffered to prevent cracks and the like from occurring in the transparent resin plate.

[0006]

However, in the windproof / snowproof plate according to the above-mentioned prior application, the rubber packing is interposed between the transparent resin plate and the frame member, but the vibration is sufficiently damped. It was not possible to prevent the occurrence of cracks in the transparent resin plate, and it was not possible to reliably prevent the problem. On the other hand, in order to solve the above-mentioned problem, it is considered effective to interpose a vibration damping member made of nonwoven fabric, glass cloth or the like between the transparent resin plate and the frame member or the reinforcing member together with the rubber packing. However, glass cloth and the like are soft and difficult to handle as compared with rubber packing and the like, and glass cloth and the like must be provided on the rubber packing, which impairs workability when assembling the transparent resin plate and the frame member and the like. The problem arises.
