Description

Technical Field

[0001] The utility model relates to the technical field of indoor ceiling decoration, in particular to a profile corner structure with an inner circle and an outer square. Background Art

[0002] In modern architecture, aluminum alloy profiles have been widely used in the construction industry. For example, in the field of indoor ceiling decoration, aluminum profiles are widely used. In indoor ceilings, the angle between two adjacent walls and the top of the wall is generally turned by installing corner profiles, but it cannot enhance the three-dimensional sense and layering sense of the corner.

[0003] In the existing ceiling profile corners, the corners are completed by beveling the joints of the profiles at a 45° angle and installing corner brackets. However, in actual installation, the joints of the corners are too obvious, and some customers require curved corners. In order to achieve curved corners, the profiles need to be bent. The bending cost of the profiles is high, and the bending angle is not easy to grasp. The integrated installation of the bent profiles is more complicated and not convenient for on-site splicing and disassembly. In addition, a gap will be exposed at the angle between the bent profiles and the wall, affecting the use effect. Utility Model Content
