Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a metal curtain wall corner structure and building facade. Background Technology

[0002] Using aesthetically pleasing architectural facades is an important means of enhancing building quality. In order to create a pleasant urban landscape, modern residential building facades often adopt public building-style facade designs.

[0003] Building facades are no longer confined to regular rectangular shapes. Some beveled angles are used to optimize the proportions of the building facade, while the quality of the building is improved by using metal or metal-like materials.

[0004] The existing method for constructing the facade of residential buildings generally involves shaping concrete and then spraying it with imitation metallic paint, which is relatively low-cost. However, it is difficult to construct and pour concrete for some special shapes, which leads to a longer construction period. If an all-metal curtain wall is used, the construction is more convenient, but the cost is higher.

[0005] Currently, no effective solutions have been proposed for the problems existing in related technologies, such as the difficulty of using concrete to shape the exterior of existing buildings and the high cost of all-metal curtain walls. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by providing a metal curtain wall corner structure and building facade, thereby solving problems such as the difficulty of using concrete molding for the existing building facade design and the high cost of all-metal curtain walls.

At the same time, the junction of the first and second decorative units is not easily deformed, thus forming a visual unity. This solves the problems of the difficulty in constructing concrete molding for existing building facades and the high cost of all-metal curtain walls. Attached Figure Description
