The embodiment provides a saddle plate reinforcing structure of a K-shaped intersecting node, which is arranged on the K-shaped intersecting node, wherein the K-shaped intersecting node comprises a main pipe 1 and two branch pipes 2, the two branch pipes 2 are connected with the main pipe 1 and arranged at a set angle, the saddle plate reinforcing structure comprises a saddle plate 3, a middle rib plate 4 and two clamp plates 5, the saddle plate 3 is saddle-shaped and fixed on the outer wall of the main pipe 1, the saddle plate 3 penetrates through a gap between the two branch pipes 2, the two clamp plates 5 are vertically fixed on the saddle plate 3 and have a distance, two opposite ends of the middle rib plate 4 are respectively connected with the outer walls of the two branch pipes 2, and part of the middle rib plate 4 is vertically inserted between the two clamp plates 5 and connected with the two clamp plates 5.
Because the main pipe 1 and the branch pipes 2 of the K-shaped intersecting joint are generally connected by intersecting welding, each branch pipe 2 is intersected at the intersecting joint of the main pipe 1 and generates a shearing force along the axial direction of the main pipe 1 and a shearing force perpendicular to the axial direction of the main pipe 1, the saddle plate reinforcing structure is arranged to balance and reduce an out-of-plane shearing force perpendicular to the axial direction of the main pipe 1 in advance and transmit the shearing force along the axial direction of the main pipe 1, the stress of the main pipe 1 and the branch pipes 2 is improved, and the punching and shearing bearing capacity of the K-shaped intersecting joint is effectively enhanced.
Specifically, the K-shaped intersecting joint comprises a main pipe 1 and two branch pipes 2, wherein the two branch pipes 2 are connected with the main pipe 1 and are arranged at a set angle to form a K-shaped structure. It should be understood that only two branch pipes 2 may be connected to the main pipe 1, and that there may be cases where more branch pipes 2 extending in other directions are connected, which is not limited by the present application.
In this embodiment, the saddle plate reinforcing structure includes a saddle plate 3, a middle rib plate 4, and two clamping plates 5, the saddle plate 3 is saddle-shaped and fixed on the outer wall of the main pipe 1, and the bottom of the middle rib plate 4 is clamped between the two clamping plates 5. Part of the acting force of the branch pipe 2 on the main pipe 1 can be transmitted to the clamping plate 5 through the middle rib plate 4, then transmitted to the saddle plate 3 through the clamping plate 5, and finally transmitted to the main pipe 1 through the saddle plate 3, and in the force transmission process, the saddle plate 3, the middle rib plate 4 and the two clamping plates 5 play a certain role in load sharing, so that the stress of the main pipe 1 and the branch pipe 2 is improved.
In this embodiment, the saddle plate reinforcing structure of the K-shaped intersecting joint further includes two side rib plates 6, and the two side rib plates 6 are respectively connected to the outer walls of the two branch pipes 2 and the outer wall of the main pipe 1. The side rib plates 6 are arranged to directly connect the branch pipe 2 with the main pipe 1, so that the stress of the main pipe 1 and the branch pipe 2 can be further improved, and the punching and shearing bearing capacity of the K-shaped intersecting joint can be effectively enhanced.

Furthermore, the positions of the middle rib plate 4 and the side rib plates 6 close to the intersecting joint are provided with cut angles 7 for avoiding intersecting weld joints of the main pipe 1 and the branch pipes 2.

It should be understood that the application does not impose any restrictions on the number, location and distribution of the welded oblong holes 8 in the oblong hole plug welded connection.
Compared with the traditional reinforcing modes such as thickening the wall thickness of a steel pipe, welding inner stiffening ribs and the like, the saddle plate reinforcing structure provided by the embodiment is only suitable for the engineering completion of a space structure, the saddle plate reinforcing structure can be implemented before and after the construction is completed through the mode of externally welding the saddle plate reinforcing structure, the application range is wider, and only the saddle plate 3, the middle rib plate 4 and the two clamping plates 5 with proper machining sizes need to be welded and fixed on site on the K-shaped intersecting node, so that the reinforcement can be realized.
