Rotating blade type wind resistance outdoor advertising board

Abstract

The invention discloses a rotating blade type wind resistance outdoor advertising board. The rotating blade type wind resistance outdoor advertising board comprises double-faced advertising board blades which can rotating along an horizontal spindle, stand columns which are placed on the two sides of the blades and used for fixing the spindle, stopping blocks on the outer sides of the stand columns of the spindle, special-shaped rotating stopping blocks and spring stop pins. All the blades ensure that the spindle can not be rotated easily under the self gravity of the blades and limiting of the spring stop pins on the lower portions of the special-shaped stopping blocks. In windy weather, the effect of wind loads overcomes the limit of the gravity of the blades and the resistance of the spring stop pins, the blades rotate to a certain angle (smaller than 90 degrees), the horizontal force supplied to an entire advertising steel structure under the effect of wind loads is greatly reduced, and therefore it is guaranteed that the advertising board can not be damaged. The rotating type wind resistance outdoor advertising board is simple in structure, the total thickness of the advertising board is small in size, formed pictures are attractive, the structure of the rotating blade type wind resistance outdoor advertising board has high wind resistance capacity, the safety performance under large wind loads is guaranteed, the service life is long, and good economic benefits are achieved.

Description

technical field [0001] The invention relates to a floor-standing independent column steel structure billboard, in particular to a rotating leaf type wind-resistant outdoor billboard. Background technique [0002] The floor-standing independent column steel structure billboard has the characteristics of towering structure and top-heavy. It adopts the structure of independent column and double cantilever beam. An independent concrete foundation is used under the steel pipe column. Advertising panels are divided into two-sided and three-sided types, which mainly bear wind loads and earthquakes. The design, production, and installation processes are complicated and the cost is relatively high. Although the independent column billboard is a structural system with regular shape and mature technology, due to the uneven professional quality of the design unit and the technical personnel of the advertising company, many billboards have potential safety hazards, and engineering accid...

AI Technical Summary

Problems solved by technology

When there is a sudden gust of wind, it is often seen that some billboards are blown over or damaged, and fall to the ground, causing considerable losses and even personal casualties

Especially for those billboards located on the top of high-rise buildings, the wind load is even greater and the damage is more serious
