Specifically, the ring frame 2 is bonded and welded to the inner side walls of the first end 11 and the second end 12 of the cylindrical section structure, and the transverse bearing capacity, the inner pressure and the outer pressure of the cylindrical section structure are reinforced through the ring frame 2.
In the embodiment of the invention, the sheet metal skin material is used as the wall plate of the storage tank barrel section structure, the ring frames 2 are welded at the two ends of the barrel section structure to strengthen the transverse bearing capacity, the internal pressure and the external pressure of the barrel section structure, and compared with the three-dimensional modeling drawing speed of the grid reinforcement design using aluminum alloy in the prior art, the sheet metal skin embossing design has the advantages of high processing speed, simplified structure, simple manufacturing process and low cost compared with the grid reinforcement wall plate.
As shown in fig. 1 to 4, in some embodiments, the press protrusion 13 is provided with a plurality of protrusions 131, and the plurality of protrusions 131 protrude toward the outer circumferential surface of the press protrusion 13; the bulge 131 is capsule type, and the central axis of the bulge 131 of capsule type is parallel with the central axis of the sheet metal skin cylinder 1. In addition, the protrusions 131 of the capsule are uniformly distributed on the press protrusion 13 along the circumferential direction of the sheet metal skin cylinder 1, that is, the protrusions on the press protrusion 13 are designed in an array in the circumferential direction.
In this embodiment, the capsule-shaped bulge 131 is used as the reinforcing rib of the sheet metal skin cylinder 1, and the size of the bulge 131 can be calculated through simulation to obtain an optimal design structure, that is, the deformation amount of the sheet metal skin cylinder 1 can be reduced as much as possible under the condition that external force is applied to the same. In the prior art, a storage box with a conventional grid reinforcement structure is usually designed according to experience in the design of the grid reinforcement structure, the three-dimensional modeling calculation amount of the design is large, the drawing speed is low, and the structural form is not an optimal solution.
