Description
1 Preparation Principles and Application Scope
1.1 Preparation principles
This Atlas is a revision of original 86SD566. Considering the successive revision of the national standard GBJ 57-83 Design Code for Protection of Structures against Lightning and other relevant standards in 1990s, the International Electrotechnical Commission and other countries successively published new standards. This Atlas is prepared based on the standards.
1.2 Application scope
This Atlas applies to Class II and Class III lightning protection buildings. The foundation earth lead also applies to earth lead required to be arranged for buildings other than Class I, Class II and Class III lightning protection buildings.
2 Preparation bases
In terms of standards of the People's Republic of China
GB 50057-94 Design Code for Protection of Structures against Lightning (2000 Edition)
GBJ 65-83 Specifications for the Design of Grounding (Earthing) of Industrial and Civil Electric System (Trial)

3 The close cooperation of constructors in the disciples of civil work and electric system is very important to reach the technical purpose of this Atlas. It is recommended that: the construction in building and structural components be carried out by the constructors of civil work discipline while that out of building and structural components be carried out by constructors of electric system or lighting protection disciple. The constructors of civil work discipline may be also responsible for the construction out of building and structural components which is less in construction amount.
4 The exposed steel parts over the ground shall be painted with one pass of minium oil and two passes of anticorrosive paint.
5 Exposed lightning protection device over the ground shall be installed as detailed in the relevant standards and atlases.
6 Earthing device applied into the soil under the ground shall be installed as detailed in the relevant standards and atlases.
7 Most of building metals and embedded parts are concealed into the concrete, so it is impossible to remedy on completion of construction. It is recommended that the constructors and supervisors for electric system and lightning protection devices actively learn about and check whether the civil construction being carried out meets the relevant design requirements and timely make a correction.

9 The practice of this Atlas can provide the following advantages: safety, reliability, long service life, the least maintenance work, without using galvanized steel and without interfering with facade decoration of buildings.
As a complete or most of the devices are buried in the buildings and structural members or using metal brake of the building and structure, the service life can last a long term, even as long as that of the buildings. Sometimes the construction may be complicated, but after the completion, less maintenance is needed during the service of the buildings;in most cases, there is no need to maintain the devices. On the contrary, the exposed special lightning protection device and artificial earth lead buried in the soil shall be replaced for several times due to corrosion, etc. during the service life of buildings, supposed to be 50-100 years.Therefore, when the building metals are used as the devices, the construction expenses of the first time may be expensive (in most cases, it is not necessarily expensive), but from the point of service life of buildings, the expenses are economic, moreover, the steels for special device may not be needed in most cases.
