Description

Technical Field

[0002] Curtain wall structure Curtain wall is the exterior wall enclosure of a building. It is non-load-bearing and is hung like a curtain. It is a lightweight wall with decorative effects commonly used in modern large and high-rise buildings. It is composed of panels and a supporting structure system. It can have a certain displacement ability relative to the main structure or a certain deformation ability of itself, and does not bear the effects of the main structure. It is an exterior protective structure or decorative structure of the building.

[0003] In the related art, the building curtain wall includes horizontal beams, vertical beams and glass. The horizontal beams and vertical beams are provided with embedded grooves. The horizontal side of the glass is fixed in the embedded grooves of the horizontal beams, and the vertical side of the glass is fixed in the embedded grooves of the vertical beams, so that the glass is fixed between the horizontal beams and the vertical beams. Usually, the fire resistance of steel and aluminum alloy profiles of glass curtain walls is relatively poor. Once a fire occurs in a building, the temperature rises rapidly. Under heat conditions, the structure is very likely to deform and lose its bearing capacity. For this reason, we propose a fire-proof structure for building curtain walls, which aims to reduce the speed of fire spread when a fire occurs in the curtain wall structure, and to ensure the safety of personnel and the stability of the building.
