Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an outdoor glass curtain wall grounding test point. Background Art

[0002] After the glass curtain wall of a high-rise building encloses the high-rise building, due to the shielding effect of the glass curtain wall, the lightning protection device of the building cannot directly play the role of lightning receiving and lightning protection. The lightning strike on the building often becomes a lightning strike on the glass curtain wall. At the same time, due to the effect of lightning, the metal material of the high-rise building glass curtain wall will produce an electrostatic induction effect. When a thundercloud in the sky forms an electric field with the ground, the metal body of the glass curtain wall will accumulate a large amount of induced charges with the opposite polarity to the thundercloud. When the thundercloud discharges instantaneously, the electric field between the cloud and the ground suddenly disappears. At this time, the induced charges on the metal body of the glass curtain wall cannot dissipate at a corresponding speed, and a ground potential of more than ten thousand volts will be generated, which is the electrostatic induction voltage and will cause harm to people and equipment.

[0003] All the external glass curtain walls of this project are double-layer glass curtain walls, with high requirements for the grounding test points, which need to be made at the position outside the glass curtain wall. Currently, this method is rarely used.

[0004] The traditional project grounding test point is installed on the building exterior wall panel, and a hole is drilled on the exterior wall to fix the test point panel with expansion bolts.

[0005] If the grounding test point is installed in the traditional way, it is necessary to drill internal threaded holes on the glass curtain wall. The glass of the external glass curtain wall is double-layer glass. If holes are drilled, it is impossible to ensure that ash layers and other sundries between the double-layer glasses enter, polluting the glass curtain wall. By adopting a new appearance design and new process construction, the pollution of the glass exterior wall can be reduced, the economic and social benefits can be improved, and the construction period can be shortened.
