Reinforcing linking system for internal and external corners at back edges of building aluminum mold

The invention relates to the technical field of building mold plates, in particular to a reinforcing linking system for the internal and external corners at the back edges of a building aluminum mold.An internal corner linking fastener and an external corner inking fastener are included, the internal corner linking fastener and the external corner inking fastener are both includes U-shaped steeland connecting parts, the connecting parts are arranged in openings of the U-shaped steel, the internal corner linking fastener is composed of the two U-shaped steel with the openings facing outwardsand being connected with each other, and the external corner linking fastener is composed of the two U-shaped steel with the openings facing inwards and being connected with each other. According to the reinforcing linking system for the internal and external corners at the back edge of the building aluminum mold, compared with existing methods of on-site welding, the reinforcing linking system can be recycled for many time
