Description

Technical Field

[0001] The present invention relates to the technical field of curtain wall engineering, and relates to a connection structure between a curtain wall and a wall and a construction method thereof, in particular to a connection structure and a construction method that can effectively solve the problem that the vertical connection between a glass curtain wall and a wall at a joint is prone to deformation. Background Art

[0002] Buildings will deform under the action of external factors. A deformation joint is a structural joint reserved for the cracking of a building caused by external factors. Building components expand and contract due to vibration and temperature changes. Usually, vertical joints are set at appropriate parts of the building, disconnecting components such as the foundation, building walls, floors, and roof panels, separating the building into several independent parts.

[0003] When there is a deformation joint between a building glass curtain wall and a wall, the glass curtain wall and the wall need to be disconnected to form independent parts. The connection structure between the glass curtain wall and the wall needs to effectively relieve the expansion and contraction deformation pressure on both sides of the deformation joint and ensure that the connection can be stable and reliable.

[0004] Therefore, it is of great practical significance to develop a connection structure between a curtain wall and a wall that meets the requirements of deformation joints. Summary of the Invention
