What is the connection of the building approved by the engineering system?
The connection of all metal components of a building is called bonding, which is said to be co-potentialization (co-voltage), which in Section 13 emphasizes its proper implementation from the foundation to the roof of the building with a suitable conductor. This edition refers to the conductor from the topic, which is the last edition in 1995, and does not allow construction rebar.

Types of connections in the building can be divided into two general categories: main and additional (supplementary) so that the main connection of the building structure and foundation of the building and the foundation includes the foundation, floors and roof. From the foundation to the roof should be connected. For additional connection, valves and water pipes (if metal) and gas pipes and four metal sticks, doors, windows and false ceilings are required.
But what is the correlation agenda? First, in the foundation, the perimeter ring of the structure, as well as the perimeter ring of the staircase and elevator, is closed, and then the transverse seats of the building are added and branched into 5 main pillars of the building so that they communicate with other floors. And this command is also executed except for the middle cross paths in the building on other floors than the roof.
What are the benefits of building bonding?
Lightning protection and no need to use lightning conductors, and also due to the Faraday cage, we will not see any electric shock because electricity can not penetrate into the connection space.
Connection of the Central Council A comprehensive and useful instruction was prepared in 1994 by a group of electrical experts of the Central Council, according to which all buildings are obliged to implement the connection, but it definitely needs to be improved because it is 6 years old.

Before execution, it is better to prepare a plan and execute accordingly. The basis of the drawing should be based on the standard of national regulations and the methodology of the Central Council or up-to-date international standards.
