Fire-resistant building curtain wall

Abstract

The invention discloses a fire-resistant building curtain wall. The fire-resistant building curtain wall comprises a shell assembly, a transmitting assembly and a fire-resistant assembly; the fire-resistant assembly comprises a dehydrant layer, a foaming source layer and a carbonizing agent layer, the dehydrant layer is located on the inner side wall of a honeycomb core and fixedly connected withthe honeycomb core, the foaming source layer is located on the inner side wall of the dehydrant layer and fixedly connected with the dehydrant layer, and the carbonizing agent layer is located on theinner side wall of the foaming source layer and fixedly connected with the foaming source layer; by arranging the foaming source layer in the honeycomb core, the honeycomb core is heated to be expanded, the effect of blocking air is improved, and fire resistance is facilitated; by arranging the carbonizing agent layer in the honeycomb core, the carbonizing agent layer is heated to form activated carbon, and then the effects of insulation and heat transfer blocking are achieved, so that the fire-resistant property of the building curtain wall is improved; by arranging the dehydrant layer in thehoneycomb core, water in the carbonizing agent layer is removed, and the carbonizing agent layer is assisted in being converted to be the activated carbon.

Description

technical field [0001] The invention belongs to the technical field of building curtain walls, and in particular relates to a flame-retardant building curtain wall. Background technique [0002] Building curtain wall refers to the non-load-bearing outer wall enclosure of a building, usually composed of a panel and a supporting structure behind it. The building curtain wall is composed of a supporting structure system and a panel, which can have a certain displacement capacity relative to the main structure and does not share the main structure. The external enclosure structure or decorative structure of the building is affected. The curtain wall is the external wall enclosure of the building. It is not load-bearing and hangs up like a curtain, so it is also called a hanging wall. Lightweight wall for decorative effect. [0003] Traditional building curtain walls are mostly used to decorate building exterior walls. They are light in structure and widely used in building exte...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a flame-retardant building curtain wall to solve the problem that the traditional building curtain wall proposed in the above-mentioned background technology has single performance and poor flame retardancy. The use also affects the development and promotion of building curtain walls, and the installation stability of traditional building curtain walls is poor. Affected by the external environment, it is prone to loosening and falling off over time.
