One end portion of the second hoop 5-4 is hooked with the end portion of the first hoop 5-3, and the other end of the second hoop 5-4 is fixedly connected with the first hoop 5-3 through a bolt 5-5. The hoop assembly 5 is installed on the column 2 in the form of one end being hooked and the other end being fixed with a bolt, improving the installation convenience of the hoop assembly 5. At the same time, the split structure of the hoop assembly 5 is more convenient for processing the first hoop 5-3 and the second hoop 5-4.

[0029] An engaging groove 5-6 is provided at the end portion of the first hoop 5-3, and a connecting head 5-7 is provided at the end portion of the second hoop 5-4. The connecting head 5-7 has a T-shaped structure, thus facilitating the hooking of the connecting head 5-7 with the engaging groove 5-6.

[0030] Convex portions 5-8 are provided on both the first hoop 5-3 and the second hoop 5-4. The connecting member 4 is installed on the outer side of the convex portion 5-8, and then the waist-shaped hole 4-1 of the connecting member 4 is connected with the convex portion 5-8 through a locking bolt 5-2, thereby facilitating the adjustment of the position of the connecting member 4.

[0031] In some alternative embodiments, an insertion slot 5-1 is formed between the end face of the convex portion 5-8 and the end face of the first hoop 5-3 or the end face of the second hoop 5-4. The connecting member 4 is inserted into the insertion slot 5-1, and the connecting member 4 is locked in the insertion slot 5-1 by a locking bolt 5-2. Preferably, one end of the screw of the locking bolt 5-2 is located outside the convex portion 5-8, and the other end extends into the convex portion 5-8. A nut is installed on the screw, and the nut abuts against the connecting member 4, thereby locking the connecting member 4 and the insertion slot 5-1.

[0032] The connecting member 4 includes a first connecting plate 4-2 and a second connecting plate 4-3 which are arranged perpendicular to each other. The first connecting plate 4-2 is fixedly connected to the prefabricated external corner 3 by self-tapping screws. A kidney-shaped hole 4-1 is provided on the second connecting plate 4-3. The kidney-shaped hole 4-1 is connected to the locking bolt 5-2 to realize the connection between the connecting member 4 and the column 2. Through the setting of the kidney-shaped hole 4-1, it is convenient to adjust the positional relationship between the second connecting plate 4-3 and the convex portion 5-8, so as to ensure that the outer end face of the prefabricated external corner 3 and the outer end face of the wall panel 1 are located on the same plane.

[0033] A rib plate 4-4 is connected to the edge of the second connecting plate 4-3. The rib plate 4-4 can guide the second connecting plate 4-3 to be installed into the insertion slot 5-1 or limit the installation of the second connecting plate 4-3 outside the convex portion 5-8, and can also increase the strength of the second connecting plate 4-3 to prevent the connecting member 4 from deforming during use, thereby increasing the stability of the prefabricated building.
