[0030] As shown in Figures 1-6 The present application relates to a funnel-shaped dome, including a dome structure 1 and a support structure 2. The dome structure 1 is composed of a funnel part 11, a ring-shaped transition part 12, a plane beam system part 13 and a peripheral overhanging part 14, and each part is connected and fixed through a precisely designed node, forming a spatial net shell structure with good bearing capacity. In the embodiment of the present application, the funnel part 11, the ring-shaped transition part 12, the plane beam system part 13 and the peripheral overhanging part 14 are connected and fixed to form a spatial net shell structure, and through the reasonable layout and close connection between each structural component, the stability and strength of the overall structure are improved, thereby realizing the technical effect of effectively dispersing and transferring the load in the large-span dome structure 1, and further solving the technical problems of uneven stress and local deformation easily occurring in the large-span dome structure 1. Specifically:

[0031] The funnel part 11 of the embodiment is composed of a plurality of 200×80×8 rectangular tubes, which are connected to each other through drum nodes to form a stable funnel-shaped structure. The high point of the funnel part 11 is 36.413 meters high, and the low point is 28.413 meters high, with a height difference of 8 meters, which can enhance the geometric stability of the overall structure.

[0032] In the embodiment, the transition part 12 is located at the peripheral edge of the funnel part 11 and is connected to the top edge of the funnel part 11. Its main function is to serve as a transition area to connect the funnel part 11 and the external plane beam system part 13, ensure uniform transmission and transition of force, and avoid local stress concentration.

[0033] In the embodiment, the plane beam system part 13 extends radially outward around the ring-shaped transition part 12 and is arranged in a radial pattern by a plurality of steel box beams. The steel box beams are connected to the ring-shaped transition part 12 through nodes and further extend to the peripheral overhanging part 14 for supporting the external area of the dome and uniformly dispersing the load to ensure the lateral stability and integrity of the structure.

[0034] In the embodiment, the peripheral overhanging part 14 is connected to the outer edge of the plane beam system part 13 to provide additional coverage area. This part extends to the outermost side of the dome, realizing a large-span coverage and effectively increasing the internal use space of the building.

[0035] Specifically, the support structure 2 comprises a main structure column 21 and a support pipe 22 obliquely supported between the main structure column 21 and the dome structure 1; the main structure column 21 is mainly used for supporting the weight of the dome and stabilizing the integrity of the structure. The support pipe 22 is made of seamless steel pipe, and part of the support pipe 22 is fixedly connected with the main structure column 21 and the dome structure 1 by means of intersecting welding to form a rigid connection; and the other part of the support pipe 22 is connected with the main structure column 21 and the dome structure 1 by means of a pin shaft to form a hinged joint, which can provide a certain flexibility for the dome and ensure good structural adaptability and stability under external forces such as wind load or earthquake. The design of the support pipe 22 by means of intersecting welding and pin shaft hinging improves the flexible adaptability of the structure, can cope with complex external loads, and ensures the long-term safe operation of the dome.

[0036] From the above description, it can be seen that the application achieves the following technical effects: in the embodiment of the application, the funnel part 11, the annular transition part 12, the flat beam system part 13 and the peripheral overhanging part 14 are connected and fixed to form a spatial net shell structure, and through the reasonable layout and close connection between the structure parts, the purpose of improving the stability and strength of the overall structure is achieved, thereby realizing the technical effect of effectively dispersing and transferring the load in the large-span dome structure 1, and further solving the technical problems of uneven stress and local deformation easily occurring in the large-span dome structure 1.

[0037] The above only describes the preferred embodiments of the application and is not used to limit the application.
