Among them, the arrangement of the U-shaped groove, on the one hand, helps to exhaust during the covering process of the membrane in the skin stage, and at the same time, helps the transition of the membrane when covering the top of the prefabricated frame. On the other hand, for the cylinder body with a cross section of a regular hexagon or a regular octagon, the U-shaped groove helps the prefabricated frame to be formed. Specifically, for the cylinder body with a circular cross section, the prefabricated frame is a corresponding circle, and a plurality of U-shaped grooves are arranged in a ring array on the top of the prefabricated frame. For the cylinder body with a cross section of a regular hexagon or a regular octagon, the prefabricated frame is a corresponding regular polygon, and a plurality of U-shaped grooves are arranged on the top of the corner of the prefabricated frame.
[0013] Preferably, a plurality of rubber rings are sleeved on the outer wall of the positioning groove, and the plurality of rubber rings are uniformly distributed at equal distances along the center line of the cylinder body.
