Description

Technical Field

[0001] This utility model relates to the field of space frame technology, specifically to a connection structure for steel space frame nodes. Background Technology

[0002] In space frame structures, nodes serve to connect converging members, transmit internal forces within them, and connect the space frame to roof structures, ceilings, piping, suspended cranes, and other components, thus transferring loads. Therefore, nodes are a crucial component of space frame structures. If the space frame is composed of circular tubes, drilling is required to secure the node fittings; otherwise, the node clamps are prone to misalignment. Drilling holes in the fittings, however, can affect the tube structure and reduce the overall strength of the space frame. Therefore, a method is needed that eliminates the need for drilling holes in the fittings.

[0003] Existing patents, such as the one published in CN220598762U, describe a connection device for a steel structure space frame node. This device includes a male clamp, a female clamp, and two connecting buckles. The male clamp consists of two opposing clamp components (first type), and the female clamp consists of two opposing clamp components (second type). Each clamp component (first type) has a protrusion on its side, and each clamp component (second type) has a groove that mates with the protrusion. The male and female clamps engage with each other through the protrusion and groove. One end of the connecting buckle is hinged to the male clamp, and the other end is hinged to the female clamp. The engagement of the protrusion and groove, along with the hinged connections of the connecting buckle to the male and female clamps, prevents the node device from shifting on its own.

[0004] While the aforementioned patent solves the problem of drilling holes in the round tube to avoid node misalignment and strengthens the overall strength of the space frame, the simple external connection via the hinged connection between the two ends of the connecting buckle and the male and female clamps means that when the space frame at the node is under stress, it is impossible to guarantee the stress balance of each space frame at the node, which can lead to the space frame breaking at the node in severe cases.

A connecting device 3 is installed between the four space frame supports 2 and the node ball 1 in a mirror image. Specifically, a groove is opened on the surface of the node ball 1 to accommodate the insertion of the space frame supports 2. The space frame supports 2 are inserted into the groove and welded to the node ball 1. The four space frame supports 2 and the node ball 1 are connected to each other through the connecting device 3, which serves to provide support and limit the movement.
