AI Technical Summary
When manufacturing the Tianyuan local dock in remote areas, traditional processes require bending machines to assist in the production, which makes it difficult to find a suitable bending machine with a specification when the raw materials are thick, resulting in higher manufacturing costs.
The sky round and place joint structure consisting of triangle plates and transition plates is adopted, where the triangle plates and transition plates are flat plates. The sky round and place joints are formed by inclination and sealing splicing, which avoids the bending process and is sealed and spliced by welding.
The manufacturing cost of manufacturing Tianyuan local joints in remote areas has been reduced, and since there is no need to bend, the material utilization rate is higher and the production is more convenient.

[0002] In the manufacturing process of the traditional technology of round-square-square butt joints, when it is inconvenient to make a curved surface, or the parallel line method and radial line method cannot be used to make an unfolded view, the curved surface is often divided into several small "triangular curved surfaces", and then the small triangular planes are treated as small "triangular curved surfaces" to make an unfolded view. This approximate unfolding method is often called the "triangle method", and then a bending machine is used to assist in completing the bending of several small triangular planes. Although with the rapid development of the domestic economy, bending machines have been widely used, but in remote areas, when thicker raw materials need to be bent, it is likely that a bending machine of suitable specifications cannot be found nearby, and it is necessary to go to a distant place to find a bending machine of suitable specifications, which has a high manufacturing cost.

[0026] The utility model provides a round-sky and square-square butt joint.
[0027] A round-square-square joint includes a triangle plate 1 and a transition plate 2. The triangle plate 1 and the transition plate 2 are flat plates respectively. The triangle plates 1 and the transition plate 2 are inclined from the bottom to the top toward the inner side of the joint. There are four triangle plates 1 and four transition plates 2 respectively. The bottom sides of the four triangle plates 1 form a rectangle. The vertices of the four triangle plates 1 are located on the same circle. A triangular notch is formed between each two adjacent triangle plates 1. The triangular notch corresponds to the transition plate 2 one by one and is sealed and spliced. The top edge 3 of the transition plate 2 is an arc that arches downward. The opposite ends of the top edge 3 coincide with the vertices of the two adjacent triangle plates 1 respectively. The projection of the four top edges 3 along the height direction of the joint after combination and the projection of the vertices of the four triangle plates 1 along the height direction of the joint after connection are all circular and coincide with each other. In a specific embodiment, the sealed splicing is performed by welding.
[0028] In the technical solution proposed in the present application, the bottom edges of the four triangle plates 1 form a "square", and the vertices of the four triangle plates 1 and the top edges 3 of the four transition plates 2 form a "circle", forming a circle-square-square butt joint; the triangle plates 1 and the transition plates 2 are both flat plates and do not need to be bent, which reduces the manufacturing cost of the circle-square-square butt joint in remote areas.
[0029] The round-square joint also includes a circular transition pipe 4. The vertices and the four top edges 3 of the four triangle plates 1 coincide with the outer circumference of the transition pipe 4. The vertices and the top edges 3 of the triangle plates 1 are sealed and spliced with the outer circumference of the transition pipe 4. In a specific embodiment, the sealed splicing is welded.
[0030] The round-to-square-to-earth joint further comprises a flange 5 , which is arranged on the end surface of the transition pipe 4 away from the triangular plate 1 .
[0031] The four triangles 1 are triangle A6, triangle B7, triangle C8 and triangle D9. Triangle A6 and triangle C8 are arranged opposite to each other, and triangle B7 and triangle D9 are arranged opposite to each other. Triangle A6 is an isosceles triangle.

The length of the base side of triangle B7 is 950mm, and the height of triangle B7 is 490mm. The three sides of triangle C8 are 995mm, 689.9mm, and 689.9mm respectively, and the three sides of triangle D9 are 950mm, 682.4mm, and 682.4mm respectively.
[0032] The set squares A6, B7, C8 and D9 have the above-mentioned sizes and are arranged reasonably so that the bases of the four set squares 1 form a rectangle and the vertices of the four set squares 1 are located on the same circle.
[0033] The transition plate 2 is cut from a triangular plate E10, and the three sides of the triangular plate E10 are 301 mm, 689.9 mm and 682.4 mm in length respectively.
[0034] The triangle plate E10 adopts the above-mentioned size, which can make the sealing splicing of the transition plate 2 and the triangle plate 1 more convenient.
[0035] It should be noted that in order to more clearly illustrate the working principle of the present invention, when describing the triangle plate 1 and the transition plate 2, the triangle plate 1 and the transition plate 2 are imagined to have a thickness of zero. In actual work, the thickness of the triangle plate 1 and the transition plate 2 can be determined according to actual conditions.
