Wind damage proof billboard frame

Abstract

The invention provides a wind damage proof billboard frame; the billboard plate is arranged on the upper end of an upright post; the billboard plate is composed by covering and fixing the advertising screen panels on the frame; the billboard plate and the upright post are made in bi-direction relative rotation connection structure along the shaft and having circular rotor and circular seat; the rotor and the seat are mated into circular body and sleeved on the upper end of the upright post; the circular rotor is fixedly connected with the billboard frame; the circular seat is fixed with the upper end of the upright post. The design refers to the wind vane structure, when the wind power of the billboard plate is more than the weight of the billboard plate, the billboard plate will rotate left or right along the upright post and raise to change the direction such that the side load wind automatically reduce the sail area; when the wind power of the billboard plate is less than the weightof the billboard plate, the billboard plate automatically turns around the upright post and descends to restore the showing direction. The diameter of the upright post can decrease, and the area of the billboard can increase; the invention has simple structure, reduced maintenance cost, and effectively solves the problem that the existed outdoor large billboard is easy to be destroyed by strong wind or typhoon.

Description

technical field [0001] The invention relates to the technical field of billboard production, in particular to a new wind-resistant design for a single-column outdoor billboard frame. Background technique [0002] Existing outdoor large-scale billboard frames that are more used, such as the billboards on both sides of the road, are to firmly install the rectangular plates on the upper end of a cement cylinder. Wind resistance is the main design factor of the diameter of the cement column, the depth of burial in the ground, and the area of ​​the billboard. Therefore, the existing billboard cement columns or steel pipe columns are relatively thick, which increases the cost of materials and construction, and the area of ​​the billboard cannot be as expected. To reduce the area exposed to wind, however, many large outdoor billboards are still destroyed by strong winds or typhoons every year, and the restoration project is equivalent to a new investment. To solve the problem of w...

Problems solved by technology

Wind resistance is the main design factor of the diameter of the cement column, the depth of burial in the ground, and the area of ​​the billboard. Therefore, the existing billboard cement columns or steel pipe columns are relatively thick, which increases the cost of materials and construction, and the area of ​​the billboard cannot be as expected. large to reduce the area exposed to wind, however, there are still many large outdoor billboards destroyed by strong winds or typhoons every year, and the restoration project is equivalent to a new investment

To solve the problem of wind resistance, in addition to the above measures, many places have changed the screen materials of billboards from metal plates to flexible materials such as canvas. When a typhoon warning is issued, manpower will be sent to roll up the screen materials, and the screen materials will be restored after the typhoon. , coupled with the typhoon's false alarm phenomenon, such as the typhoon turning temporarily, the maintenance cost of the billboard is quite high
