Description

Technical Field

[0001] The utility model belongs to the technical field of construction, in particular to a lightning protection facility for a building. Background Art

[0002] At present, lightning protection for buildings is achieved by installing lightning rods on the top of the buildings. The lightning rods installed on the top of the buildings can guide direct lightning and induced lightning to the ground. With the rapid development of my country's economy, super-high-rise buildings and high-rise buildings are emerging in an endless stream. In order to make the appearance neat and beautiful, they are often designed in the form of stone curtain walls, metal curtain walls, aluminum curtain walls, etc., especially glass curtain walls.

[0003] The load-bearing structure of the curtain wall is mainly made of horizontal and vertical metal keels. Due to the effect of lightning, electrostatic induction will occur. When the thunderclouds in the sky and the earth form an electric field, the metal body of the curtain wall will accumulate a large amount of induced charge with the opposite polarity to the thunderclouds. When the thunderclouds discharge instantly, the electric fields between the clouds and the earth suddenly disappear. At this time, the induced charge of the metal body of the curtain wall cannot dissipate at the corresponding speed, which will generate a ground potential of more than 10,000 volts, causing great harm to people and equipment in buildings.

[0004] Lightning protection of curtain walls has always been a design focus. In specific construction, multiple sections of columns are usually connected through flexible wires. In this process, the connection between the flexible wires and the columns is mostly fixed by bolts. After long-term use, the bolts may become loose, resulting in a loose fit between the flexible wires and the columns, affecting the conductive effect. Therefore, a building lightning protection facility is needed to improve the stability of the wire fixing bolts, thereby reducing the possibility of loosening, and thereby improving the excellent conductivity of the wire to the column.
