Description

technical field [0001] The invention relates to the technical field of building curtain walls, in particular to an ultra-low energy consumption building curtain wall frame profile device and a manufacturing method. Background technique [0002] The building curtain wall is the non-load-bearing outer wall enclosure of the building. It is hung on it like a curtain, so it is also called a hanging wall. It is a light-weight wall with a decorative effect commonly used in modern large-scale and high-rise buildings. The biggest feature it gives to buildings is to organically unify factors such as architectural aesthetics, building functions, building energy efficiency and building structure, so that buildings show different hues from different angles, and give people a sense of harmony with the changes of sunlight, moonlight and light. Constructed beauty. Building curtain walls are usually composed of panels (glass, metal plates, stone plates, ceramic plates, etc.) and supporting ...

AI Technical Summary

Problems solved by technology

[0003] The existing building curtain wall uses metal materials as the supporting frame structure, so there are some limitations, such as poor fire protection and heat insulation performance, high energy consumption, etc.

The metal materials used in the existing building curtain wall supporting frames are mainly steel and broken bridge aluminum alloy. Steel has high load-bearing performance, but has poor heat insulation performance, high thermal conductivity, and high energy consumption; broken bridge aluminum alloy has good heat insulation performance and heat conduction. The coefficient is low, but the existing broken bridge aluminum alloy is to penetrate two heat-insulating strip profiles in the middle of the aluminum alloy profile, and the aluminum alloy profile is divided into two parts by the two heat-insulating strip profiles, which blocks heat conduction and reduces heat conduction coefficient, but the existing heat-insulating strip profiles usually use PA66 material, which has low strength. To achieve a lower heat transfer coefficient, the cross-sectional width of the heat-insulating strip must be increased, but when used as a profile with a larger cross-section, the strength of PA66 is difficult to support The weight of the building curtain wall panel, in addition, PA66 material cannot meet the fire protection requirements of the building curtain wall, and the aluminum alloy profile and the heat insulation bar profile are mechanically snapped and connected. Thermal expansion and contraction cause gaps in the connection between the aluminum alloy profile and the heat insulation bar profile, which reduces the mechanical connection strength and load-bearing performance, and is prone to water seepage and wind. The inner aluminum alloy profiles of the alloy are in contact, forming a heat conduction bridge and reducing the heat insulation performance
