National standards for bridges mainly include the following:1. GB/T 3044-2018 "Bridge": the standard specifies the terminology and definition of bridge, classification, materials, structure, size, technical requirements, acceptance inspection, marking, packaging, transportation and storage, etc.2. GB 23239-2009 "specification for equipment room engineering": the standard specifies the basic requirements for the construction of equipment rooms, including the geographic location of the equipment room, building design, air conditioning, ventilation, power supply, lighting, lightning protection, safety, management, etc., which includes installation specifications for bridges. Including the geographical location of the server room, building design, air conditioning, ventilation, power supply, lighting, lightning protection, safety, management and other aspects of the content, including the installation of the bridge specification. 3, GB 50168-2014 "Electric Power Engineering Construction Quality Acceptance Specification": the standard specifies the basic requirements for the acceptance of the quality of construction of electric power projects, including pre-construction, construction, completion and acceptance of the acceptance of the various stages of the content of the acceptance, including the bridge. 4, GB 50171-2015 "building electrical engineering construction quality acceptance specification": the standard specifies the basic requirements for the acceptance of the construction quality of building electrical engineering construction, including pre-construction, construction, completion and acceptance of various stages of acceptance, including the acceptance of the bridge specification. The above standards are formulated by the state, through the standardization of bridge design, manufacturing, installation and acceptance requirements, to ensure the quality and safety of the bridge, improve the use of the bridge. Bridge national standards and norms for fire retardant aspects of the introduction mainly includes the following aspects: 1, steel bridge: GB/T 3044-2018 "bridge" provides that the steel bridge should meet the fire rating of not less than A, such as in high-rise buildings, large public places, subway and other places to use in accordance with the requirements of the architectural fire protection design of fire protection treatment. 2, stainless steel bridge: GB / T 28117-2011 "building electrical engineering stainless steel bridge" stipulates that the stainless steel bridge should have fireproof performance, not less than class A. 3, FRP bridge: CJJ/T 92-2014 "General Technical Specification for Building Electrical Engineering" stipulates that the FRP bridge should meet the requirements of the fire level of the building, can be flame retardant FRP materials. 4, aluminum alloy bridge: YD/T 1095- 2008 "communication bridge and its accessories", "communication bridge and its accessories". 2008 "communication bridge and its accessories" stipulates that the aluminum alloy bridge should be made of flame retardant materials to achieve the fire rating of not less than Class A. In summary, the bridge national standards for fire-retardant requirements are more stringent to protect the bridge in the use of the process of safety and stability.
