[0020] In order to make the technical means, creative features, objectives and effects of the utility model easier to understand, the utility model is now further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the relevant components of the utility model.

[0021] According to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0022] The technical solution of the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] Embodiment 1, as Figures 1 to 3 As shown, a steel structure dome node connection structure includes a first steel beam 1 and a second steel beam 2. The first steel beam 1 and the second steel beam 2 are welded and fixedly connected. The connection surfaces of the two need to be flush, and the connection is set at an obtuse angle. After a steel structure composed of multiple first steel beams 1 and second steel beams 2 welded at an obtuse angle is used to form an arc-shaped dome. It can be considered that the steel structure connected by the first steel beam 1 and the second steel beam 2 is the main beam, which plays a major role in supporting the dome.

[0024] In addition, first side beams 3 are fixed on both sides of the connection between the first steel beam 1 and the second steel beam 2. The connection surfaces of the first side beam 3, the first steel beam 1 and the second steel beam 2 are set at an obtuse angle, which is used to extend the steel structure dome from the side to establish a curved dome structure. The first side beam 3 plays a role in auxiliary support of the dome, and it constitutes the extension surface of the dome.

[0025] In addition, bolts 31 are respectively provided at the connecting ends of the first steel beam 1 , the second steel beam 2 , and the first side beam 3 , and the three can be connected to other steel structure components through the bolts 31 , thereby completing the construction work of the dome.

[0026] This solution assembles the first steel beam 1, the second steel beam 2, and the first side beam 3 by welding, so that they have the function of modular installation, which is convenient for construction operations, improves work efficiency, reduces working hours, and gradually decomposes the project volume into each dome node connection, making subsequent construction more convenient.

[0027] Embodiment 2, based on Embodiment 1, a steel structure dome node connection structure, a first bevel 32 is provided at the connection between the first side beam 3 and the first steel beam 1 and the second steel beam 2, and the inclination angle of the connection between the first bevel 32 and the first steel beam 1 and the second steel beam 2 is 0-60 degrees. When the plane where the first bevel 32 and the first steel beam 1 and the second steel beam 2 are connected is 0 degrees, it is perpendicular to the plane where the first steel beam 1 and the second steel beam 2 are connected, and when the plane where the first bevel 32 and the first steel beam 1 and the second steel beam 2 are connected is 60 degrees, it is inclined to the plane where the first steel beam 1 and the second steel beam 2 are connected. The structural diagram can be seen in Figure 3 shown.

[0028] As a preferred solution, a second side beam 4 is further provided at the connection between the first steel beam 1 and the second steel beam 2. A second bevel 41 and a socket 42 are provided at the connection end of the second side beam 4. The second bevel 41 is fixedly connected to the connection between the first steel beam 1 and the second steel beam 2. The socket 42 abuts against the outer wall of the first side beam 3 and is fixedly connected by welding. By providing the second bevel 41 and the socket 42 at the connection between the second side beam 4, it is convenient to fix with the plane where the connection between the first steel beam 1 and the second steel beam 2 is located and the outer wall of the first side beam 3, so that the three are symmetrically arranged at the positions on both sides with the plane where the connection between the first steel beam 1 and the second steel beam 2 is located as the reference, and the dome is expanded to form a curved surface structure.

[0029] As a preferred solution, the cross-sections of the first steel beam 1, the second steel beam 2, the first side beam 3, and the second side beam 4 are all rectangular ring structures. That is to say, the cross-sections of these steel beams are hollow "U"-shaped structures, which saves the structure of manufacturing the dome and does not require splicing. "U"-shaped steel can be directly purchased from outside and cut into a certain length as the raw material for manufacturing.

[0030] When implementing, see Figure 6 and Figure 7 A connecting plate 6 is provided on the top of the first steel beam 1, the top of the second steel beam 2, the top of the first side beam 3, and the top of the second side beam 4, respectively. The connecting plate 6 is provided with a mounting hole. The outer side of the dome is covered with a covering, such as glass, sunshade, high-transparency plate, iron plate, concrete precast plate and other decorative materials, through the connecting plate 6 and the mounting holes on the connecting plate 6.

[0031] Example 3, based on Example 1, please refer to Figure 4 and Figure 5, a steel structure dome node connection structure, also includes a polygonal tube 5, which is mainly used at the top of the dome and is an important node where the top gathers all around. The polygonal tube 5 has at least four sides to fix the steel beams in the four directions of front, back, left, and right. The first steel beam 1 and the second steel beam 2 are respectively fixed on the two symmetrical side walls of the polygonal tube 5, and the first side beam 3 is fixed on the other side wall of the polygonal tube 5, and is symmetrically arranged with the plane where the first steel beam 1 or the second steel beam 2 is located.

[0032] In one embodiment, in order to better extend the dome, the polygonal tube 5 is designed as an octagonal structure with eight evenly spaced side walls.

[0033] Specifically, the polygonal tube 5 includes a top cover 51, a bottom cover 52 and a side plate 54. There are eight side plates 54 and they form an octagonal structure. The top cover 51 is fixed to the top of the octagonal structure, and the bottom cover 52 is fixed to the bottom of the octagonal structure. Inner plates 53 are evenly distributed at the angles in the octagonal structure, and the inner plates 53 are centrally symmetrical in the octagonal structure. When installing the inner plates 53, one of the plates can be cut according to the length of the two inner plates 53 as the central axis of symmetry, and the other inner plates 53 are evenly welded and fixed at the center of the inner plate 53 at the same angle.

[0034] During implementation, the bottom of the first steel beam 1 at the bottom is connected to the base 7, and then the nodes formed by the welding and fixing of the first steel beam 1 and the second steel beam 2 continue to extend upward to form multiple similar structures, and the node polygonal tube 5 is welded and fixed at the top node of the dome, and other nodes connected to the first steel beam 1 and the second steel beam 2 are arranged and welded around the polygonal tube 5 until an arc surface is formed. Finally, the connection plate 6 is installed on each node, and the outer side is covered with a covering through the connection plate 6 to complete the construction of the dome.
