Open type double-layer curtain wall system and installation method thereof

The invention relates to an open type double-layer curtain wall system and an installation method of the open type double-layer curtain wall system. An inner-layer curtain wall is formed by mutually splicing inner-layer curtain wall modules; in each inner-layer curtain wall module, the edge of the inner-layer curtain wall module is connected with an anchor board, the anchor board is connected with a keel through a T-shaped connection component, the T-shaped connection component is fixedly connected with a first L-shaped connection component, the first L-shaped connection component is connected with a bearing component, the bearing component is in socket connection with an insertion component, the insertion component is connected with a second L-shaped connection component, the second L-shaped connection component is connected with an outer-layer curtain wall, and the outer-layer curtain wall is formed by mutually splicing outer-layer curtain wall modules; an open type double-layer curtain wall is formed in a manner that the inner-layer curtain wall modules and the outer-layer curtain wall modules are mutually in parallel andgaps are reserved between the modules. The open type double-layer curtain wall system has the advantages that the structure is simple, and the installation is convenient; when the energy-saving loss of a double-layer curtain wall is met, the air motion between the inner-layer curtain wall and the outer-layer curtain wall is ensured; furthermore, the inner-layer curtain wall and the outer-layer curtain wall are connected by a connection system, and the connection system utilizes a socket connection manner, so that the connection process is simple and convenient; the open type double-layer curtain wall system can be widely applied to installation of curtain walls.
