Technical Field

[0001] This utility model relates to the technical field of Y-type cast steel nodes, and in particular to a Y-type cast steel node with three-way stiffening ribs. Background Technology

[0002] In steel structure buildings, nodes serve as connection points. Steel structure projects typically have large spans and complex structural forms, resulting in diverse node constructions. Application number CN202121775251.9 discloses a Y-shaped cast steel node with three-way stiffening ribs, comprising a cast steel node body arranged in a Y-shape, with three-way stiffening rib components within the body… This patent improves the overall strength of the node by using simple stiffening ribs; however, the support effect of simple stiffening ribs is limited and cannot meet usage requirements. Therefore, we present a Y-shaped cast steel node with three-way stiffening ribs. Utility Model Content

[0021] Please see Figure 1-4 This utility model provides a technical solution:

[0022] A Y-shaped cast steel joint with three-way stiffening ribs includes a cast steel joint body 1. The cast steel joint body 1 includes a first joint 11, a second joint 12, and a third joint 13. The first joint 11, the second joint 12, and the third joint 13 are integral structures and are triangularly distributed. The inner wall of the first joint 11 is fixedly connected with a third stiffening rib 16 and two fourth stiffening ribs 17. The third stiffening rib 16 is located between the two fourth stiffening ribs 17. Between, the inner wall of the second node 12 is fixedly connected to the sixth stiffening rib 19 and two fifth stiffening ribs 18. The sixth stiffening rib 19 is located between the two fifth stiffening ribs 18. The inner wall of the third node 13 is fixedly connected to the first stiffening rib 14 and two second stiffening ribs 15. The first stiffening rib 14 is located between the two second stiffening ribs 15. The first stiffening rib 14, the third stiffening rib 16 and the sixth stiffening rib 19 have the same structure. The two second stiffening ribs 15, the two fourth stiffening ribs 17 and the two fifth stiffening ribs 18 have the same structure.

[0023] In this embodiment, the first stiffening rib 14 includes a crossbeam 141. The upper left and upper right portions of the crossbeam 141 both have through holes 144 extending vertically. A longitudinal beam 142 is fixedly connected to the lower middle portion of the crossbeam 141. The right end of the longitudinal beam 142 has three through slots 143 extending horizontally. The crossbeam 141 and the longitudinal beam 142 are fixedly connected to the inner wall of the third node portion 13. The longitudinal beam 142 does not contact the two second stiffening ribs 15. The second stiffening ribs 15 include a first reinforcing rib 151, a second reinforcing rib 153, and a third reinforcing rib 155. The first and third reinforcing ribs 153 and 155 are triangularly distributed. Each of the first, second, and third reinforcing ribs 151 and 153 has several second through slots 152. Several support members 154 are fixedly connected to one adjacent end of each of the three reinforcing ribs 151, 153 and 155. The support members 154 are all "V" shaped structures. The second reinforcing rib 153 is fixedly connected to the third node 13. The first, second, and third reinforcing ribs 151 and 153 are all fixedly connected to the crossbeam 141.

[0024] Through the above scheme, the No. 2 stiffening rib 15 is closely composed of three key parts: the No. 1 stiffening rib 151, the No. 2 stiffening rib 153, and the No. 3 stiffening rib 155. The No. 1 stiffening rib 151, the No. 2 stiffening rib 153, and the No. 3 stiffening rib 155 are closely connected by several support members 154. These support members 154 not only play a bridge-like connecting role, firmly fixing the three stiffening ribs together, but also significantly enhance the overall synergistic effect between the three stiffening ribs through their own rigidity and strength.

[0025] It should be noted that this utility model describes a Y-shaped cast steel node with three-way stiffening ribs. By setting a first stiffening rib 14 and two second stiffening ribs 15 in the third node 13, the first stiffening rib 14 and the two second stiffening ribs 15 cooperate with each other to provide solid and reliable support and reinforcement for the third node 13. The second stiffening rib 15 is closely composed of three key parts: a first reinforcing rib 151, a second reinforcing rib 153 and a third reinforcing rib 155. The first reinforcing rib 151, the second reinforcing rib 153 and the third reinforcing rib 155 are tightly connected by several support members 154. These support members 154 not only play a bridge-like connecting role, firmly fixing the three reinforcing ribs together, but also significantly enhance the overall synergistic effect between the three reinforcing ribs through their own rigidity and strength. They act like strong bonds, which greatly improve the overall strength of the No. 2 stiffening rib 15. The No. 1 stiffening rib 14 and the two carefully designed No. 2 stiffening ribs 15 work together to provide comprehensive and powerful support for the No. 3 node 13.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
