The holes 44a to 44c, the stopper pin 45, and the plate spring 46 that constitute such a height adjusting mechanism are similar to the joint structure of the above-mentioned split pipes. On the other hand, a leg plate 48 fixed to the ground by a nail 49 is attached to the lower end of the inner pipe 7B. The leg plate 48 has a base portion 48a fitted into the lower end opening of the inner pipe 7B and prevented from coming off by a pin 50, and a nail hole 51 into which the nail 49 is inserted. The nail hole 51 is provided in the vertical surface including the stopper pin 45, and serves as a mark indicating the position of the stopper pin 45.

In FIGS. 1, 3 and 5, the ridge corner joint 8 has a main body 8A made of cast aluminum formed in a chevron shape, and a fitting hole provided at one end with a central portion of the main body 8A. And a joint pipe 58 made of aluminum fitted in 59. The joint pipe 58 forms a joint portion with the ridge pipe 3, and both end portions of the main body 8A form joint portions with the gas palm pipe 6, respectively. It is the cylindrical portion 60 for forming the palm-growing pipe. The joint pipe 58 is fitted to the inner peripheral surface of the split pipe 3A (or 3C) at the time of joining with the ridge pipe 3, and has a leaf spring (not shown) inside thereof and the leaf spring. A stopper pin 61, which is normally projected to the outside of the joint pipe 58 and is fitted into the fitting hole 12 (FIG. 2) of the split pipe 3A (or 3C), is incorporated. The palm-arranging pipe cylindrical portion 60 has a fitting hole 63 on the circumferential surface, and when one end of the joint-manipulating pipe 6 is fitted, the stopper pin 36 is fitted into the fitting hole 63 so that the joint-manipulating pipe 6 is fitted. And ridge corner joint 8 are connected.

In FIGS. 1, 3 and 6, the eaves corner joint 9 is a main body 9A made of cast aluminum which is bent in a three-pronged shape, and one end portion of the main body 9A is fitted in a central portion of the main body 9A. An aluminum joint pipe 71 fitted in the hole 70. The main body 9A integrally includes a horizontal beam pipe cylindrical portion 72, a diagonal pipe cylindrical portion 73 directed obliquely upward and a pillar pipe cylindrical portion 74 directed vertically downward, and these three cylindrical portions 72 to 74 are provided. Are all provided in the same vertical plane. Also, the stopper pins 32, 39, 43 of the beam pipe 5, the gas pipe 6 and the column pipe 7 are fitted to the peripheral surfaces of the beam pipe cylinder portion 72, the gas pipe pipe cylindrical portion 73 and the column pipe cylinder portion 74. Joint holes 76, 77, 78 are formed respectively.
