The outer walls of the threaded hollow steel pipe 3 and the vertical hollow steel pipe 5 are respectively provided with vertical holes 14 and steel pipe holes 16 for inserting the bolts 4. The threaded hollow steel pipe 3 is L-shaped. The outer wall is provided with a thread, and the outer wall thread of the threaded hollow steel pipe 3 is provided with a nut 8 for fixing the position of the clamp 1 and the vertical flat steel 2. The installation assembly includes a vertical sleeve 9, and a circular hole is provided at the bottom end of the clamp 1. The vertical sleeve 9 is sleeved inside the circular hole, and the vertical joint steel bar 10 is sleeved inside the vertical sleeve 9. The clamp 1 is L-shaped, and a longitudinal hole 13 for inserting the threaded hollow steel pipe 3 is provided on one side of the clamp 1. The clamping assembly includes a spring clip 11, and one side of the spring clip 11 is fixedly connected to one side of the bottom of the vertical flat steel 2. A ring 15 for inserting the threaded hollow steel pipe 3 is provided on the top of the vertical flat steel 2.

[0022] It should be noted that two fixtures 1 and a vertical flat steel 2 are set at the crossbar of the threaded hollow steel pipe 3. The two fixtures 1 are respectively set on both sides of the vertical flat steel 2. The number and longitudinal spacing of the vertical flat steel 2, the threaded hollow steel pipe 3 and the vertical hollow steel pipe 5 are consistent. The diameters of the longitudinal holes 13 and the rings 15 are 1.02 times the outer diameter of the threaded hollow steel pipe 3, so as to ensure that the fixtures 1 and the rings 15 can pass through the threaded hollow steel pipe 3. The rings 15 are set At the top of the vertical flat steel 2, the vertical flat steel 2 consists of two sections, and the two sections of the vertical flat steel 2 are fixed to the top and bottom ends of the circular ring 15 by welding respectively, so that the two sections of the vertical flat steel 2 are in the same straight line, and the outer wall of the top of the vertical sleeve 9 is fixedly connected to the inner wall of the circular hole of the clamp 1 by welding. The depth of the vertical sleeve 9 is 5 cm, and its inner diameter is 1.02 times the diameter of the vertical joint steel bar 10. The thread of the outer wall of the threaded hollow steel pipe 3 is meshed with the thread of the inner wall of the nut 8.

[0023] Furthermore, the length of the fixture 1 is 12m, and a plurality of longitudinal holes 13 are opened 1m away from the end of the fixture 1, and the spacing between the plurality of longitudinal holes 13 is 2m. The vertical flat steel 2, the threaded hollow steel pipe 3 and the vertical hollow steel pipe 5 are a group, and a group is set at a spacing of 2m.
