Externally-hung assembly type enclosure wall based on side pin type wedge-shaped self-locking connection

The invention discloses an externally-hung assembly type enclosure wall based on side pin type wedge-shaped self-locking connection, comprising prefabricated wall pillars. A groove is formed in the side wall of each prefabricated wall pillar. Support heads of prefabricated wall boards are accommodated in the grooves. Pin blocks for fixing are arranged between the support heads and the grooves. A limit structure is formed in each pin block. Each limit structure includes an inclined clamped surface formed on one side of the corresponding pin block and an inclined fixed surface formed on one groove wall of the corresponding groove, and the inclined clamped surface and the inclined fixed surface are meshed with each other to prevent the pin block from sliding out. The externally-hung assemblytype enclosure wall has a simple and reasonable structure and a good appearance effect, and is easy to process and install. By using assembly type connecting joints, the connection is reliable, the construction is efficient,
