1. Introduction
Three sided flipping billboards are widely favored by advertisers due to their unique rotating display effect. This form of advertising can attract the attention of passersby and increase the exposure rate of the advertisement. In the process of designing a three sided billboard, structural design and material selection are two crucial factors that directly affect the safety, durability, and display effect of the billboard. This article will explore the design and material selection of three sided flip billboards from these two aspects.
2、 Structural Design
support structure
The support structure of a three sided billboard usually needs to have sufficient strength and stability to withstand the influence of wind and other external factors. Common forms of supporting structures include steel frames and concrete foundations. Steel frames are widely used due to their lightweight and high strength, but wind load analysis is required during design to ensure the stability of billboards under strong wind conditions. The concrete foundation provides additional wind resistance, especially suitable for large billboards.
Flip mechanism
The flipping mechanism of the three sided flipping billboard is its core part, and commonly used flipping methods include electric drive and mechanical drive. Electric drive systems are usually equipped with motors and transmission devices, which can achieve efficient and smooth flipping. The mechanical drive system flips through the principle of leverage and gravity, with a relatively simple structure and easy maintenance. The choice of flipping mechanism should consider frequency of use, maintenance costs, and power supply conditions.
Advertising surface design
The design of advertising should fully consider the visual effects and display requirements of advertising content. Usually, advertising surfaces are made of aluminum alloy or PVC board materials, which have good imaging effects while ensuring strength. In addition, considering the ease of replacement of advertisements, a structure that is easy to replace should be designed during the design process, so that the advertising content can be updated quickly and maintain freshness.
3、 Material selection
main material
The main structure is usually made of steel or aluminum alloy. Steel is widely used for its high strength and durability, but requires anti-corrosion treatment to extend its service life. Aluminum alloy is more suitable for small or lightweight billboard design due to its light weight and strong corrosion resistance.
surface material
The surface material of billboards should have good weather resistance and light resistance to ensure that the advertising content is not easily faded under long-term exposure. Printing materials usually use high-quality PVC film and special coatings, which can effectively resist ultraviolet rays and rainwater. Meanwhile, the surface material should have good self-cleaning performance to reduce maintenance frequency.
Structural connectors
The selection of connectors is also crucial in the design of a three sided flipping billboard. Appropriate bolts, rivets, and connection frames can ensure a secure connection between various components and enhance the stability of the overall structure. Materials with superior anti-corrosion properties such as 304 stainless steel should be selected to avoid safety hazards caused by corrosion.
IV. Conclusion
Three sided flipping billboards have become an important form of modern advertising due to their dynamic visual appeal. In its structural design and material selection, engineers should comprehensively consider safety, durability, and economy to achieve optimal results. By reasonable design and high-quality material selection, we ensure that billboards work stably and safely in a changing environment, thereby providing advertisers with higher investment returns.
