Embodiment 1
[0029] combine Figure 1~2 As shown, a K-grade non-prestressed stainless steel tube-concrete composite pole with a slight diameter of 190mm and a length (L) of 10m includes a stainless steel tube 100 and a concrete layer 200 poured on the inner wall of the stainless steel tube 100. The thickness of the stainless steel tube 100 is t1 is 0.5 mm, and the thickness t2 of the concrete layer 200 is 30 mm.
[0030] The stainless steel pipe 100 is composed of two half pipes cut along the axis. The stainless steel pipe 100 is provided with two rows of reserved holes 110 with a diameter of 14 mm along the length direction. The row spacing of the reserved holes 110 is 200 mm. The inner wall of the corresponding stainless steel pipe is welded with a stainless steel nut 210 with an inner diameter of 14 mm and a length of 30 mm. In this embodiment, the nut 210 embedded in the concrete layer 200 is used to fix the climbing ladder, and the climbing ladder passes through the connecting piece o...
