Description

Technical Field

[0001] The utility model relates to the field of building materials, in particular to a rectangular concave-convex connecting plate. Background Art

[0002] Curtain walls are the exterior enclosures of buildings. They are non-load-bearing and are hung like a curtain, hence the name "curtain wall." They are lightweight, decorative walls commonly used in modern large and high-rise buildings. Directly fixing curtain walls to the curtain wall frame during construction can easily create gaps, affecting their aesthetics. To ensure a tighter connection between curtain wall panels, they are typically joined together using connecting plates. Existing connecting plates are typically rectangular flat panels that can tightly connect the panels together. However, when the temperature fluctuates, the panels expand and contract due to heat and cold. After prolonged use, these panels can deform due to this expansion and contraction, making the curtain wall less aesthetically pleasing. Therefore, the proposed rectangular concave-convex connecting plate is essential to address this issue. Utility Model Content

[0003] The purpose of the utility model is to provide a rectangular concave-convex connecting plate to solve the problem that after long-term use, the curtain wall panel will be deformed due to thermal expansion and contraction, making the curtain wall no longer beautiful.
