Description

Technical Field

[0001] This invention relates to a connection node at a T-joint of an integral wall panel frame, belonging to the field of ship structural design. Background Technology

[0002] Aluminum alloy structures are prone to deformation during welding, significantly impacting structural forming accuracy. Furthermore, the presence of a heat-affected zone at the weld joint leads to a decrease in the material's mechanical properties relative to the base material, affecting structural strength. Therefore, in the design and construction of aluminum alloy vessels, especially large hovercraft, monolithic wall panels are often used in areas with relatively regular shapes. Monolithic wall panels are generally extruded integrally, and the supplied panels include both plates and reinforcing ribs. Using monolithic wall panels avoids welding between plates and ribs, saving a significant amount of weld seams, effectively reducing welding deformation and improving construction efficiency, while also reducing the weld heat-affected zone and increasing strength reserves. However, because the plates and ribs are integrated, traditional connection nodes are not suitable for monolithic wall panels, reducing design flexibility and introducing difficulties in various structural connection nodes. One type of connection node is the T-shaped connection node at the intersection of two horizontal and vertical plate frames, where traditional plate-rib combined plate frame connection nodes, such as... Figure 1 As shown (including the horizontal plate frame 11 and the vertical plate frame 12 with ribs), if this node is used on the overall wall panel frame, it will cause 1) the wall panel cutting width exceeds the actual width of the plate, resulting in low wall panel utilization and poor economy; 2) high requirements for vertical cutting control of rib end face, which can easily damage the wall panel; 3) high requirements for processing and assembly accuracy. Summary of the Invention
