Description

An aluminum alloy sun visor connection structure

technical field

The utility model relates to the technical field of curtain walls, in particular to an aluminum alloy sun visor connection structure.

Background technique

Installing sun visors on the building facade to block sunlight from entering the room is the most effective measure to improve the energy-saving effect of buildings. The larger the cross-sectional size of the sun visor, the larger the area that it blocks sunlight, and the more obvious the energy-saving effect. Since the profile of the aluminum alloy sun visor is made by extrusion process, the size of the section of the profile is limited by the profile extrusion equipment. At present, the width of the profile that can be processed by the aluminum alloy extrusion equipment does not exceed 600mm, so for the width of the sun visor For sun visors over 600mm, it is often necessary to use a combination of multi-section profiles to meet the design requirements. The connection of the sun visor can be completed in other ways such as slot type. The slot-type assembly is inserted from one side of the sun visor until the overlapping of the block profiles is reached. Although this connection method can complete the connection between two sections of profiles, it requires particularly high machining accuracy of the profiles. The large gap makes assembly easy, but it is prone to displacement and the appearance effect is poor; the small gap makes assembly difficult or even impossible.
