Description

Technical Field

[0001] This utility model belongs to the field of building door and window technology, specifically to a beveled edge pressure line ultra-low energy consumption aluminum alloy double inward opening system window. Background Technology

[0002] Driven by both the unique climate of northern my country and the rising quality of life for residents, the demands for functionality, safety, and visual appeal in building doors and windows are continuously increasing. This is especially true for high-net-worth individuals such as villa owners, owners of high-end residences, and residents of ground-floor projects with courtyards. Their needs for doors and windows have evolved from basic "wind and rain protection" to a combination of "high-performance protection and aesthetically pleasing design." Specifically, this means requiring excellent sealing performance, ultra-low energy consumption for thermal insulation, strong wind pressure resistance, and a visually harmonious integration with the building's interior facade. However, current double-opening windows on the market still face numerous unresolved technical challenges, failing to fully meet these complex requirements. These challenges are mainly reflected in the following aspects: 1. Poor functional stability: It lacks both heat insulation and wind pressure resistance, making it difficult to meet higher usage requirements. Insulation performance (K-value) fails to meet requirements: The frame thickness of the operable sash in a double inward-opening window is a significant factor affecting the overall window's heat transfer coefficient (K-value). Currently, most double inward-opening window designs do not implement a "vertical isotherm structure"—meaning the insulation cavity between the operable sash and the window frame does not extend along the isotherm, resulting in a thin operable sash (typically less than 30mm). This fails to create an effective insulation buffer zone, allowing heat to easily transfer through the thinner sash, making it difficult for the overall window's K-value to meet ultra-low energy consumption requirements.

[0003] Weak wind pressure resistance: Some double inward opening windows are designed with a focus on lightweight appearance and use small-sized profiles (e.g., profile width ≤ 100mm). Their cross-sectional moment of inertia and bending stiffness are low. In windy areas in the north (such as coastal areas and plateau areas), they are prone to deformation, loss of sealing performance and even potential safety risks due to wind load exceeding the limit.

[0004] II. The contradiction between the application trend of large glass and structural adaptability With the increasing consumer demand for large glass panes (such as panoramic windows and floor-to-ceiling windows), doors and windows need to support larger areas and heavier glass, placing higher demands on the overall structural strength and wind pressure resistance. Traditional door and window glazing designs, primarily featuring open or thin-walled closed glazing lines at the fixed glass areas, are no longer suitable for the structural requirements of large glass panes. Their main drawbacks are as follows: Opening pressure line: Due to the opening design, the stress is concentrated, and the shear and deformation resistance is weak. Under the action of positive and negative wind pressure (such as typhoons and strong winds), it is easy to loosen, break or deform, and cannot effectively fix the large glass. Thin-walled, thick-walled closed-end glazing line: Although it is a closed structure, the wall thickness is too thin, and the overall strength is insufficient. It is difficult to withstand the weight of the large glass and the bending moment and shear force generated by external wind pressure. During long-term use, there is a risk of glazing line deformation, glass shaking, or even falling off. Summary of the Invention
