高炮广告牌基础钢筋图

With its unique structure and size design, single-column billboards occupy an important position in the field of outdoor advertising. There are two main types of billboards: two-sided boards and three-sided boards. Two-sided boards are usually placed on both sides of the road with a slight tilt angle to improve the driver's perspective. Three-sided boards are used at road intersections. The common size is 18m×6m, and there are also 5m. Specifications such as ×15m and 7m×21m must comply with local city appearance management regulations. For example, Shanghai limits the size of signboards to 6m×18m.

The height of the billboard is determined by the height of the road. Usually the height of the column is 18m above the road. However, in recent years, with the pursuit of advertising effect, the height of single column billboards in some areas has been increased to 25m or even higher. Shanghai and other places have rarely adopted the 18m standard, and towering billboards have more visual impact.

The upper structure of a single-column billboard is composed of a signboard and a column. The signboard is made of welded steel frame and iron sheet. Structural strength, lightning protection and anti-corrosion are the key to the design. As a support, the column must be able to withstand the pre ssure of the billboard and wind load. It mainly adopts a single column structure with a diameter of 1m to 1.2m and a wall thickness of 10mm to 12mm. Regular maintenance is an important part of maintaining structural stability, and the structural design life is generally controlled within 15 years.

When designing and producing single-column billboards, attention must be paid to structural stability and safety. Common problems include weak welding, severe corrosion, and unreasonable structures. According to different installation locations, billboards are divided into double-sided and three-sided single columns, which are suitable for both sides of the road and intersections.

The foundation forms include self-weighted reinforced concrete foundation, pile foundation and manually dug single pile foundation. The self-weighted foundation is simple to construct but has weak wind resistance and is easily damaged in strong winds; the pile foundation has strong wind resistance, but requires a lot of equipment; the cost of manually dug piles is lower in hard soil areas, but in soft soil and wind Large areas should be used with caution.
