How to fix billboards on building facades
The production of outdoor billboards should be in compliance with the architectural design requirements of the overall layout of the building and the design of the building facade, and the construction drawings should be Close coordination with the design; twenty years is the design life of large high-post outdoor billboards, and other types of outdoor billboards are designed for ten years. The load for setting up outdoor billboards should be specified in 1. The basic wind pre ssure should be implemented at 0.45kN/m2, and the height coefficient, wind vibration coefficient, shape coefficient, etc. should be considered; for earthquake-prone areas, the combination of earthquake effects and other loads should also be considered. The steel structure used in outdoor billboards should comply with the relevant provisions of GB50017 and the "Technical Specifications for Steel Structures of Outdoor Billboards" 3, and the torsional strength check calculation of the steel structure connecting parts should be considered.
Second: The basic structure design of outdoor floor-standing billboards should meet the following requirements:
① Outdoor floor-standing billboards should be based on the soil conditions and structural foundation requirements of the construction site. And the ground foundation strength should be calculated reasonably. If necessary, the stability of the ground foundation against sliding should be calculated. The area of the bottom of the foundation away from the foundation shall not exceed 1/4 of the area of the foundation;
② Based on a rigid foundation, the usual eccentric load should comply with the "Building Foundation Design Code" GB50007 for outdoor floor-standing billboards Design;
③When the foundation is lower than the groundwater level, the buoyancy effect of groundwater on the foundation and casing should be considered, and the groundwater should not be corrosive to the foundation, and corresponding anti-corrosion treatments should be carried out;
④ When the soft soil layer of the foundation stratum is relatively thick, the upper load is large and concentrated, and the shallow foundation cannot meet the requirements for the bearing capacity and deformation of the outdoor floor-standing billboard steel structure foundation. A caisson or pile foundation can be used. The pile foundation uses pre fabricated reinforced concrete piles, cast-in-place concrete piles or steel pipe piles. This type of pile foundation should be determined after compre hensive analysis based on geological conditions, structure type, load size, construction conditions and the environment of the construction site. The calculation of the pile foundation is carried out in accordance with the "Design Code for Building Foundation Foundation" standard of GB50007.
Third: The design of the bracket base of outdoor rooftop billboards should meet the following requirements:
① Outdoor rooftop billboards should not be connected with friction expansion bolts. It is necessary to use good chemical anchors, planting bars and self-wall anchors, which must have pre cise technical parameters and quality assurance systems;
②The layout of the bracket base of the outdoor roof billboard should be consistent with the roof column With proper network layout, the billboard structure should be able to directly bear the load-bearing pre ssure, tension and shear force;
③The base of the outdoor roof billboard bracket can be welded with bolts, anchor bolts, top beams and embedded parts in the column connection, and can effectively and reliably disperse the load from the base of the advertising signage bracket to the bearing capacity of the substructure;
④ The embedded depth of concrete bolts or anchor bolts should reach 30 to 40D (d is the diameter of the bolt ); The installation of anchor bolts should meet the technical requirements of the products used. When the embedding depth is not enough, welding with beam and column steel bars should be used, and at the same time, sufficient thickness of the concrete protective layer must be ensured.
Fourth: The lightning protection and grounding design of outdoor billboards should meet the following requirements:
① Outdoor billboards should take appropriate lightning protection measures based on the environment they are in, including Protect against lightning and lightning attacks.
② Outdoor billboard lightning protection facilities (including access equipment, shunts, grounding equipment, overvoltage protection equipment and other connecting conductors) should be designed according to the lightning protection environment and the environment in which they are located. Lightning protection design must pre vent direct lightning and lightning attack measures;
③When installing outdoor billboards on the roof of a building or on an exterior wall, the lightning protection facilities can be grounded with the building's lightning protection Combined with system design;
④ When installed on the roof of a multi-story residential building, outdoor billboards should be welded to a steel structural frame, metal plate and residential building lightning protection system, and ensure that its grounding resistance is not greater than 4Ω , otherwise an additional lightning protection grounding system is required;
⑤The grounding system of outdoor billboards should form an equipotential connection;
⑥The steel structure frame, metal plates, etc. of outdoor billboards can As connecting air-termination equipment and downline lightning protection equipment, it must be connected with multi-point welding connections to the floor and wall lightning protection system down conductors;
⑦In independent outdoor billboards, in addition to being installed on protected The lightning protection belts, lightning protection nets, steel frames, metal plates and steel columns inside and outside should be effectively grounded. Grounding wires can be shared or laid separately; building lightning protection grounding and other lightning protection grounding equipment, including various types of metal pipes, should be connected to the same lightning protection grounding facility.
(1) Comply with urban appearance standards, with healthy content, standardized writing, beautiful appearance, and safety and solidity; Glass curtain walls and windows of buildings; (3) Signboard advertisements should be placed above the eaves of the first floor and below the eaves of the second-floor windows. The height and protrusion distance of the upper and lower edges of the signboards of buildings with similar styles in the same building and the same road section Should be consistent;
(4) If outdoor advertisements are provided with public facilities such as road signs, bus shelters, and garbage bins, the specifications and colors should be unified in categories, and the form and pattern should be coordinated with the street scene and kept clean and intact;
The color and picture of vehicle-mounted advertisements should be concise, bright, clean and beautiful, and shall not be placed on the front and rear windshields or window glass, and shall not affect the recognition of vehicle logos.
Article 32
: Set up outdoor billboards and store signs, plaques, placards, signs, galleries, inkjet paintings, showcases, neon lights, light boxes, banners, flags, and display screens , inflatable devices, physical modeling and other outdoor advertising facilities, a written application must be submitted to the urban management administrative department, and relevant approval procedures must be completed in accordance with relevant regulations before implementation.
To set up large-scale outdoor advertisements, a written application should be submitted to the urban management administrative department, and the approval procedures should be completed in accordance with relevant regulations before implementation.
Outdoor advertising facilities should have no less than 30% public service announcements. If outdoor advertising facilities are vacant, the installer shall temporarily set up public service advertisements.
For outdoor advertisements that are old, damaged, color-corroded, etc. that affect the appearance of the town, the installer shall repair, clean or replace them in a timely manner; for those that pose safety risks, the installer shall reinforce or dismantle them; for those that have exceeded the approved time limit or have lost their use value , the installer should dismantle it in time.
Article 33: It is prohibited to post advertisements, graffiti or depict advertising text or patterns on the surfaces of buildings, structures, corridors, public facilities, pavements, poles, trees and other objects.
