Description

Technical Field

[0001] The present invention relates to the technical field of glass curtain walls, and more specifically, to an anti-freezing and swelling structure for a glass curtain wall applicable to severe cold regions. Background Art

[0002] In severe cold regions, the traditional glass curtain wall structure often causes the glass to break or deform due to the freezing and swelling effect, affecting the building appearance and service safety. In the prior art, the bottom of the glass curtain wall usually directly contacts the ground, and the gap is only sealed with construction glue. In such a structure, in a low-temperature environment, the frozen soil swelling will squeeze the frame material of the glass curtain wall, resulting in problems such as glass breakage and damage to the exterior facade, and posing safety hazards to the surrounding personnel. In addition, there is a lack of effective anti-freezing and swelling measures in the prior art, and it is difficult to balance the heat preservation performance and structural stability. There is an urgent need for a glass curtain wall structure that can effectively resist the influence of freezing and swelling and has good heat preservation performance. Summary of the Invention
