Background
The glass curtain wall is a building external protective structure or decorative structure which has a certain displacement capacity relative to the main structure and does not bear the action of the main structure. There are both single and double glazing. The glass curtain wall is a beautiful and novel building decoration method and is a remarkable characteristic of modern high-rise building times. The glass curtain wall of modern high-rise building adopts hollow glass which is formed by combining mirror glass and common glass and filling dry air or inert gas into an interlayer. The hollow glass comprises two layers and three layers, wherein the two layers of hollow glass are sealed by the two layers of glass to form an interlayer space; the triple-layer glass is formed by two interlayer spaces formed by the triple-layer glass. The hollow glass has the advantages of sound insulation, heat insulation, frost prevention, moisture prevention, high wind pressure resistance and the like.
The glass curtain wall is not fireproof, but is a part of the building, although the glass curtain wall is arranged at the periphery of the building, the glass curtain wall also has general fire resistance and also has the same fireproof requirement as the building. The gap between the glass curtain wall and the building should be treated with fire-proof treatment. The fire-proof glue is a common construction method at present, and is used for sealing and coating a glass curtain wall and a building gap by using a non-combustible material so as to prevent a big fire from further spreading and prepare a sufficient time for escape of people.
With respect to the related art in the above, the inventors consider that: although the fireproof glue is filled between the glass and the building to realize certain fire prevention, the fireproof glue is still a pain point in the whole fireproof performance, when a fire disaster happens, the fireproof glue is easy to melt and lose efficacy, and once the fireproof glue loses efficacy, the glass curtain wall is easy to fall from the surface of the building to cause safety accidents.
