After the four legs 3, the four joints 2f, and the four horizontal members 2e are connected to each other and the bolts are tightened, the support column 4 is erected on the frame 2 as shown in FIG. To do.

To erection the support column 4 on the frame body 2, the procedure is as follows. The four arms 4c are opened to engage the engaging portions 4c2 at their respective free ends with the four horizontal members 2e, respectively. Specifically, the locking pin 4c7 of the engaging portion 4c2 is inserted into the locking hole 2d of the horizontal member 2e to lock it. The locking hole 2d is formed at an intermediate position in the length direction of the horizontal member 2e. In the engaging portion 4c2, the contact portions 4c6 and 4c5 are in contact with the upper surface 2b and the inner side surface 2c of the horizontal member 2e, respectively. The four arms 4c in which the engaging portion 4c2 is engaged with the horizontal member 2e are inclined upward from the intermediate positions of the four horizontal members 2e in the length direction toward the center of the frame body 2. As shown in FIG. 1, it forms a gassho structure that intersects on the frame body 2.

Next, the second connecting portion 2a at the four corners of the frame body 2 and the first connecting portion 4d below the guide portion 4a are connected by four wires constituting the connecting auxiliary member W, respectively. As described above, one of the four wires constituting the connecting auxiliary member W is interposed with a turnbuckle constituting the tension adjusting portion T. The three wires not intervening with the tension adjusting portion T are set to a length in which the support column 5 comes to the center position of the frame body 2, and the second connecting portion 2a is in a state where the tension by the tension adjusting portion T is relaxed. And the wire constituting the connecting auxiliary member W are connected to the first connecting portion 4d. By adjusting the degree of tightening of the tension adjusting portion T, the four wires constituting the connecting auxiliary member W are adjusted to a predetermined tension, the inclination of the support column 5 is corrected in the vertical direction, and the frame 2 Deformation from the default shape (square in the illustrated example) (deformation to a slight rhombus in the illustrated example, etc.) is corrected to the default shape. FIG. 11 is a front view showing a state in which the support column 4 is erected on the frame 2 and the four wires constituting the connecting auxiliary member W are stretched.

After the tension adjusting portion T is tightened and adjusted, the awning 7 (indicated by a virtual line) is put on the support column 4 as shown in FIG. Although not shown, the awning 7 is attached by tying a fastening string or the like attached to the awning 7 to a horizontal member 2e or the like.
