The four first reinforcing plates 11 and the inner wall of the square through slot 2 form an isosceles right triangle, using the principle that the triangle is the most stable to provide support for the magnesium-aluminum profile body 1; the hexagonal reinforcing plate 14 is a regular hexagon, and the inner radius of the cylindrical reinforcing plate 12 is equal to the side length of the hexagonal reinforcing plate 14. From a geometrical point of view, the hexagonal reinforcing plate 14 can be regarded as an inscribed regular hexagon of the cylindrical reinforcing plate 12. By setting the elastic reinforcing plate, the elastic reinforcing plate can be selectively set inside the corresponding T-shaped shrinking groove 3 according to the actual use and connection conditions, so that the strength of the magnesium-aluminum profile body 1 can be enhanced without losing the diversity of connection methods brought by the T-shaped shrinking groove 3. Preferably, the surfaces of the magnesium-aluminum profile body 1 and the elastic reinforcing plate are electroplated with an electroplating layer (not shown in the figure), and the electroplating layer is made of metallic zinc. By electroplating a layer of metallic zinc on the surface, the corrosion resistance can be improved, especially in a humid environment, zinc will form a dense oxide film on the surface to protect the body from corrosion. The electroplating layer should cover the outer surface of all structures in the utility model that can come into contact with the outside air.

At this time, the T-shaped reinforcing plate 41 and the spring blocks 44 on both sides can just be inserted into the interior of the T-shaped shrinking groove 3. As the T-shaped reinforcing plate 41 contacts the deepest inner wall of the T-shaped shrinking groove 3, the spring blocks 44 on both sides will pop out in the direction away from the T-shaped reinforcing plate 41 under the action of the spring 42 and just snap into the interior of the T-shaped shrinking groove 3. Preferably, the length of the T-shaped reinforcing plate 41 and the spring block 44 can be adjusted as needed. They can be the same length as the T-shaped shrinking groove 3 on the surface of the magnesium-aluminum profile body 1, or they can be connected in sections inside the T-shaped shrinking groove 3. When disassembling, the connection between multiple magnesium-aluminum profile bodies 1 can be released first, and then they can be slid out from their ends, or they can be directly dismantled by force.

At this time, the spring 42 is in a compressed state; the T-shaped reinforcement plate 41 and the spring blocks 44 on both sides are inserted into the interior of the T-shaped shrinking groove 3. As the T-shaped reinforcement plate 41 contacts the deepest inner wall of the T-shaped shrinking groove 3, the spring blocks 44 on both sides will pop out in the direction away from the T-shaped reinforcement plate 41 under the action of the spring 42 and just get stuck in the interior of the T-shaped shrinking groove 3.
