一、室外广告牌定制应与整体布局设计建造单位规划设计要求一致。施工图应与设计紧密协调;大型室外高炮立柱广告牌的设计使用周期为20年,其他室外楼顶屋顶墙体等类型广告牌设计使用周期为10年。室外广告牌的设置负荷应在建筑结构荷载规范要求之内。 基本风压应为0.45kN / m2,并考虑高度系数,风振系数,体形系数等。对于地震多发区,还应考虑地震冲击和其他荷载的综合因素。室外广告牌定制用钢结构应符合钢结构设计规范的有关规定和室外广告牌钢结构的技术规定,并应考虑用于计算钢结构连接件的抗扭强度。
 
1. Customization of outdoor billboards should be consistent with the planning and design requirements of the overall layout design and construction units. Construction drawings should be closely coordinated with the design; the design and use period of large outdoor anti-aircraft gun column billboards is 20 years, and that of other types of billboards, such as outdoor roof, roof and wall, is 10 years. The setting load of outdoor billboards should be within the requirements of load code for building structures. The basic wind pressure should be 0.45kN/m2, and the height coefficient, wind vibration coefficient and shape coefficient should be taken into account. For earthquake-prone areas, the comprehensive factors of seismic impact and other loads should also be considered. The steel structure for outdoor billboard customization should conform to the relevant regulations of the steel structure design code and the technical regulations of outdoor billboard steel structure, and should be considered for calculating the torsional strength of steel structural connectors.

二、室外落地式广告牌基础设施设计应符合以下标准:
 
2. The infrastructure design of outdoor landing billboards shall meet the following standards:
 
⑴室外落地式广告牌应根据土壤条件和结构施工现场的基础。并合理计算地基强度,必要时应计算地基抗滑的稳定性。地基面积不得超过地面面积的1/4;
 
(1) Outdoor landing billboards should be based on soil conditions and the foundation of the construction site. The strength of foundation should be calculated reasonably and the stability of foundation against sliding should be calculated when necessary. The ground area shall not exceed 1/4 of the ground area.
 
⑵基于刚性基础,通常的偏心载荷应符合要求符合建筑地基基础设计规范要求的室外落地式广告牌设计;
 
(2) Based on rigid foundation, the usual eccentric load should meet the requirements of outdoor landing billboard design which meets the requirements of building foundation design specifications.
 
⑶当基础低于地下水位时,地下水对地基和套管浮力的影响应为考虑到,应保护地下水不受地基影响,并进行相应的防腐处理;
 
(3) When the foundation is below the groundwater level, the influence of groundwater on the buoyancy of foundation and casing should be taken into account, groundwater should be protected from the influence of foundation, and corresponding anti-corrosion treatment should be carried out.
 
⑷当基层的软土层较厚时,上部荷载较大,集中,浅基础不能满足室外落地式广告牌钢结构基础的承载力和变形要求,可采用下沉或桩基。桩基采用预制钢筋混凝土桩,混凝土浇筑桩或钢管桩。这种桩基应根据施工现场的地质条件,结构类型,荷载大小,施工条件和环境进行综合分析和确定。桩基的计算按照建筑地基基础设计规范标准进行。
 
(5) When the soft soil layer of the base is thicker, the upper load is larger and concentrated, and the shallow foundation can not meet the bearing capacity and deformation requirements of the steel structure foundation of outdoor landing billboards, so the sinking or pile foundation can be used. Prefabricated reinforced concrete piles, concrete cast-in-place piles or steel tube piles are used for pile foundation. This kind of pile foundation should be synthetically analyzed and determined according to the geological conditions, structure type, load size, construction conditions and environment of the construction site. The calculation of pile foundation is carried out according to the design standard of building foundation.
 
三、室外屋顶广告牌制作的支架底座设计应符合以下标准:
 
3. The design of bracket base for outdoor roof billboards shall meet the following standards:
 
⑴室外屋顶广告牌不与膨胀螺栓直接相连。新加艺广告牌需要良好的化学锚,种植棒和自支撑锚。必须有精确的技术参数和质量保证体系;
 
(1) Outdoor roof billboards are not directly connected with expansion bolts. Xinjiayi billboards need good chemical anchors, planting rods and self-supporting anchors. Accurate technical parameters and quality assurance system must be established.
 
⑵室外新加艺楼顶广告牌支架底座的布局应与屋顶柱网的布局,广告牌结构应适当配合。直接可承受的压力,张力和剪切力;
 
(2) The layout of the pedestal of the advertising board bracket for the newly added art building roof outdoors should be in accordance with the layout of the roof column network, and the structure of the advertising board should be properly coordinated. Direct withstandable pressure, tension and shear force;
 
⑶室外屋顶广告牌支架底座可用于焊接柱内的螺栓,地脚螺栓,顶梁和预埋件,并可以有效可靠地将广告设置支架底座的载荷分散到下部结构的承载能力;
 
(3) Outdoor roof billboard support base can be used to weld bolts, anchor bolts, roof beams and embedded parts in the column, and can effectively and reliably distribute the load of advertising support base to the bearing capacity of the lower structure;
 
⑷混凝土螺栓或地脚螺栓应嵌入30至40公分的深度;地脚螺栓应安装充足。新加艺产品技术要求使用脚。当嵌入深度不够时,应采用梁和柱钢的焊接处理方法,并保证混凝土保护层的足够厚度。
 
(5) Concrete bolts or foot bolts should be embedded in a depth of 30 to 40 cm; foot bolts should be installed adequately. The technical requirements of new additive products are foot. When the embedding depth is not enough, the welding method of beam and column steel should be adopted, and the sufficient thickness of concrete protective layer should be ensured.
 
四、室外广告牌设计防雷接地保护应符合以下标准:
 
4. The design of lightning protection and grounding protection for outdoor billboards shall meet the following standards:
 
⑴室外广告牌应根据环境采取相应的防雷措施,包括防雷击和电击。
 
(1) Outdoor billboards should take corresponding lightning protection measures according to the environment, including lightning protection and electric shock.
 
⑵室外新加艺广告牌防雷设施,包括接入设备,分流器,接地设备,过电压保护设备和其他连接导体,应按照防雷环境设计,防止直接雷电袭击功能;
 
(2) The lightning protection facilities of outdoor Xinjiayi billboard, including access equipment, shunt, grounding equipment, overvoltage protection equipment and other connecting conductors, should be designed according to the lightning protection environment to prevent direct lightning attack function;
 
⑶当安装在建筑物屋顶和外墙的室外广告牌上时,防雷设施可与防雷接地相结合建筑物的系统设计;
 
(3) When installed on outdoor billboards on roofs and exterior walls of buildings, lightning protection facilities can be combined with lightning protection grounding system design of buildings.
 
⑷当多层住宅楼顶安装的室外广告牌应为钢结构框架时,金属板和住宅楼防雷系统焊接连接,接地电阻保证不超过4Ω,否则需要额外的防雷接地系统;
 
(5) When the outdoor billboards installed on the roof of multi-storey residential buildings should be steel frame, the metal plate and the lightning protection system of residential buildings should be welded together, and the grounding resistance should not exceed 4, otherwise additional lightning protection grounding system is needed.
 
⑸室外广告牌的接地系统应形成等电位连接;
 
(5) The grounding system of outdoor billboards should be equipotentially connected.
 
⑹室外广告牌钢结构框架,金属板等可作为连接防雷装置的防雷连接装置,但必须在地板和墙壁上多点焊接防雷系统。
 
_Outdoor billboard steel structure frame, metal plate and so on can be used as lightning protection connection devices to connect lightning protection devices, but must be multi-spot welding lightning protection system on the floor and walls.
 
⑺独立的室外广告牌,除了安装在受保护的防雷带和防雷网,钢架,金属板和钢柱外,应有效接地。接地线可以共用或另外铺设;建筑物的防雷接地和其他防雷接地设备,包括各类金属管道,应连接到同一防雷接地设施;
 
_Independent outdoor billboards shall be effectively grounded in addition to protected lightning belts and lightning protection nets, steel frames, metal plates and steel columns. Grounding wires can be shared or laid separately; lightning-proof grounding and other lightning-proof grounding equipment of buildings, including various types of metal pipelines, should be connected to the same lightning-proof grounding facilities;
 
⑻室外广告牌应为低压电源,通常应使用三相五线制电源,必须按照民用建筑电气设计规范确保接地和用电安全。
 
_Outdoor billboards should be low-voltage power supply. Usually, three-phase five-wire power supply should be used. The safety of grounding and electricity consumption must be ensured in accordance with the electrical design specifications of civil buildings.
