大型钢结构广告牌的设计和施工特点（The characteristics of the design and construction of large steel structure billboard） The characteristics of the design and construction of the building | large steel structure billboard Abstract: This paper discusses some characteristics of the design and construction of large steel structure billboard, which has certain reference value for further improvement and improvement of this new type of building. Key words: steel structure; billboard; design; construction Introduction /p In recent years, with the deepening of Chinas reform and opening up, economic construction has been rapid development, accompanied by the advertising industry is also growing prosperity. Therefore, in the design of billboard structure, the demand for its shape, scale and efficiency has also been improved. Large billboards are permanent buildings, its position in the general public, the downtown area, and most are built on the already built buildings, therefore, in order to meet the advertising effect, the safety of the structure is especially important. In addition, the construction of its basic works is generally restricted by the neighboring buildings. In this paper, the structural design and construction characteristics of large steel structure billboard are discussed according to the billboard structure, engineering design and actual construction experience on both sides of the station square in front of a railway station. General situation: the billboard is located in the flower bed on the East and west sides of the station square in front of a railway station. The width of the flower bed is 3M, and the other side is a concrete pouring square, and the other side is a plain concrete pavement. According to the on-site drilling data, from top to bottom soil engineering site is divided into three layers: the surface soil (Qm1), the layer thickness is 2.5 ~ 2.7m, with the broken brick, stone and other organic matter, the static cone penetration resistance PS=0.83 ~ 3.65MP
