Description
Technical field
The present invention relates to a kind of billboard, especially a kind of windproof advertising board.
Background technique
In modern society, advertisement has become a part in for people's lives, by various media and in a manner of appear in people
In face of, outdoor advertising is exactly one of.Outdoor advertising includes the advertisement being arranged on building and is erected at road both sides,
Such as the billboard of highway both sides.The area and height of roadside poster are much bigger compared with regular price-line advertising board, and existing roadside
Billboard be it is fixed, lower end and the ground of column are fixed, and upper end and the billboard of column are fixed.Due to billboard height
Degree is higher, often will receive the effect of front wind-force, in the case where encountering the large winds operative condition such as typhoon, the effect of billboard receiving
Power is very big, and the increase of the damage and maintenance cost of billboard is inevitably resulted in through long-term wind-force effect.
Have some vertical billboard markets in order to obtain more attention rates, be often arranged in building crossroad or
Person corner, and crossroad and corner are often air port, are that wind-force is maximum, the most and most violent region of wind vector,
This billboard for allowing for being arranged in crossing is easy to topple over, and leads to the inconvenience of Pedestrians and vehicles.
Also, the billboard at crossing is set, and since flow of the people is larger, base portion tends to be pressed by vehicle, leads
The breakage of billboard bottom is caused, is also easy to cause the unsafe conditions in vehicle driving.
Therefore be badly in need of designing a kind of billboard for being set to crossing, it can be good at radix saposhnikoviae, and pedestal is not easy by vehicle pressure
Damage.
Summary of the invention
