Garland-shaped tooth groove type aluminum alloy combined joint
The invention discloses a garland-shaped tooth groove type aluminum alloy combined joint, and belongs to the technical field of civil engineering. The garland-shaped tooth groove type aluminum alloy combined joint consists of an upper cover plate, a lower cover plate and a garland-shaped tooth groove body, wherein the plane shapes of the upper cover plate and the lower cover plate are circular, and the garland-shaped tooth groove body consists of a middle circular ring column and radial cantilever tooth grooves. Holes are pre-formed in all the radial cantilever tooth grooves of the garland-shaped tooth groove body and connected with holes in an aluminum alloy I-shaped beam web through stainless steel bolts. The pre-formed holes of the upper cover plate and the lower cover plate are connected with upper flange holes and lower flange holes of aluminum alloy I-shaped beams through the stainless steel bolts, and the aluminum alloy I-shaped beams are connected through the joints to form a reticulated shell structure. The bearing capacity, especially the shearing capacity, of a traditional plate type joint can be effectively improved. The method can be used for a larger-span single-layeraluminum alloy reticulated shell structure, and the construction manner is also suitable for a steel structure reticulated shell.
本发明公开了一种花环齿槽型铝合金组合节点，属于土木工程技术领域，节点由上下盖板及花环齿槽体组成，上下盖板的平面形状为圆形，花环齿槽体由中间圆环柱以及辐射状悬臂齿槽组成。花环齿槽体在各辐射状悬臂齿槽上预开孔，与铝合金工字梁腹板上的孔通过不锈钢螺栓连接。上下盖板的预开孔与铝合金工字梁的上下翼缘孔通过不锈钢螺栓连接，铝合金工字梁之间通过这种节点相连形成网壳结构。本发明能有效提高传统板式节点的承载力，尤其是抗剪承载力。可用于更大跨度的单层铝合金网壳结构，其构造方式也适用于钢结构网壳。
