Description

Construction structure of building curtain wall corner metal decoration strip

Technical Field

The utility model relates to the technical field of building curtain wall construction, in particular to a construction structure of a metal decorative strip for a corner of a building curtain wall.

Background

Metal molding is becoming increasingly popular in the facade applications of modern buildings. The decorative lines are rich in appearance of the outer vertical surfaces, so that the artistic characteristics of the building are fully represented, and more importantly, the delicate decorative lines can better show the grade of the building. Curtain walls have gradually become marks of modern buildings, and the appearance effect of decorative lines is achieved through metal curtain wall materials, and the curtain walls have been greatly applied and developed in recent years.

However, the conventional metal decorative lines often adopt open-mold spray-coating sectional materials with smaller sections or metal plates with limited widths, and are not enough in atmosphere in artistic expression when applied to outer-facade curtain walls; when large metal lines are bent by adopting large metal plates, the large metal lines often have the problems of poor flatness and large installation errors when being applied to curtain walls, and are not delicate enough in short; furthermore, the lines using the stainless steel panel are often only used for store spaces or partial facades of less than 50 meters, and the curtain wall facades of super high-rise buildings are rarely used in a large scale. Due to the characteristics of stainless steel materials, the stainless steel strips are difficult to refine when the section is large, and the materials corresponding to the large section are stacked easily to be huge and heavy, so that the stainless steel strips are further hindered from being used and developed in the field of the outer facade curtain wall of the super high-rise building.

In the existing curtain wall construction process, if metal decorative strips exist, the metal decorative strips and curtain wall glass are assembled into a unit plate in a factory, and then the unit plate is installed in place on a construction site. However, in the mounting process, due to the problems of machining precision, building construction precision and the like, error gaps exist between the rod-shaped units, so that gaps (staggering) occur between the decorative strips. The reflective tape can appear under the condition of night lamplight irradiation, and the decorative effect is seriously affected. And cannot be adjusted.
