[0002] With the continuous development of high-rise building design and construction technology, more and more high-rise buildings have begun to adopt steel-concrete combined stress-bearing structural forms. Among these structural forms, the application of oblique woven steel outer mesh tube combined with concrete inner tube is becoming more and more widespread, such as famous buildings such as Guangzhou Tower. The steel outer mesh tube is relatively unfavorable in terms of stress due to its cross-shaped diamond grid. In actual design, it is often necessary to increase the stiffness of the outer mesh by setting a ring beam to improve its stress condition. However, how to design a structure to set a ring beam without affecting the architectural effect of the outer mesh has become a major design problem. In addition, the connection method between the steel outer mesh tube and the concrete inner tube, especially the connection node design between the strut and the steel outer mesh tube, is also a key issue that needs to be considered in the structural design. In previous design schemes, the strut and the steel outer mesh tube are mostly connected by hinged connection at both ends, but how to achieve a reliable and beautiful connection is still a challenge.

[0026] In the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0027] like Figure 1 As shown, a steel ring beam-external network non-coplanar connection node is provided, in which the steel strut 1, the steel ring beam 4 and the steel external network 6 are arranged in sequence from the inside to the outside, that is, the steel strut 1, the steel ring beam 4 and the steel external network 6 are not coplanar, and the steel ring beam 4 is retreated into the curved surface where the steel external network 6 is located, and at the same time is reliably connected to the strut, which makes it impossible to see the steel ring beam 4 outside the building, while ensuring that the ring beam and the external network are subjected to force in coordination, thereby ensuring the strength and rigidity of the external network.
[0028] The inner end of the steel strut 1 is fixedly connected to the concrete inner tube, and the steel strut 1, the steel ring beam 4 and the steel outer net 6 are fixedly connected via a connection node.
[0029] The connection node includes: an outer ear plate 2, an inner ear plate 7 and a pin 3. The inner end of the outer ear plate 2 is fixedly connected to the outer end of the steel support rod 1, the outer end of the inner ear plate 7 is fixedly connected to the inner side of the steel outer net 6, the middle part of the inner ear plate 7 is fixedly connected to the steel ring beam 4, and the inner end of the inner ear plate 7 is connected to the outer end of the outer ear plate 2 through the pin 3.
[0030] The inner ear plate 7 is fixedly connected to the outer ear plate 2, the steel ring beam 4 and the steel outer net 6, thereby achieving the purpose of fixedly connecting the steel support rod 1, the steel ring beam 4 and the steel outer net 6.
[0031] In order to achieve the connection between the steel support rod 1 and the outer ear plate 2, a longitudinal connecting port is set at the outer end of the steel support rod 1, the outer ear plate 2 is vertically arranged, and the inner end of the outer ear plate 2 is inserted into the connecting port and welded to the steel support rod 1.
[0032] As the name implies, the outer ear plate 2 is located on the outside of the inner ear plate 7. Therefore, the outer ear plate 2 in this embodiment includes a double-layer plate and a single-layer plate. The single-layer plate is inserted into the connecting port, and the double-layer plate is fixedly connected to the single-layer plate and the steel support rod 1. The inner end of the inner ear plate 7 is inserted between the double-layer plates, that is, the inner ear plate 7 is "clamped" by the double-layer plate (the movement can be restricted to a certain extent, but in order to avoid interference with the work of the pin 3, there is still a gap between the double-layer plate and the inner ear plate 7), and then connected to the double-layer plate through the pin.
[0033] In order to increase the strength of the outer ear plate 2 , the outer ear plate 2 further includes a plurality of reinforcing ribs, and the plurality of reinforcing ribs are fixedly connected to the outer side surface of the double-layer plate and the outer end surface of the steel support rod 1 .
[0034] The steel ring beam 4 is a plurality of rectangular steel tubes connected end to end, and the inner ear plate 7 is vertically arranged between two adjacent rectangular steel tubes and fixedly connected to the rectangular steel tubes. That is, when welding the steel ring beam 4, the inner ear plate 7 is directly welded to the steel ring beam 4, so that the connection between the inner ear plate 7 and the steel ring beam 4 is stable.
[0035] Similar to the function of the reinforcing ribs, in order to increase the connection stability between the steel ring beam 4, the inner ear plate 7 and the steel outer net 6, the connection node also includes a connecting plate 5, which is horizontally arranged and fixedly connected to the inner side of the steel outer net 6, the steel ring beam 4 and the inner ear plate 7.
[0036] In order to keep the upper and lower stresses of the inner ear plate 7 similar, there are multiple connecting plates 5. The upper connecting plate 5 is parallel to the upper flange of the steel ring beam 4, and the lower connecting plate 5 is parallel to the lower flange of the steel ring beam 4.
[0037] In order to ensure that the connection node is firmly connected to the steel outer mesh 6, because the steel outer mesh 6 is a diamond structure made of round steel, the inner ear plate 7 and the connecting plate 5 are both provided with an arc structure adapted to the steel outer mesh 6. The arc structure is just adapted to the outer circumferential surface of the round steel, making the welding more secure.
[0038] The fixed connections between the connection nodes and the steel struts 1, the steel ring beams 4 and the steel outer mesh 6 are all welded.
[0039] As a better example, when the connecting plate 5 is connected to the steel outer mesh 6, both ends of the connecting plate 5 are 50 to 100 mm wider than the outer edges of the rods of the steel outer mesh 6, and the net space between the steel ring beam 4 and the steel outer mesh 6 is 50 to 150 mm.
