Embodiment Construction

[0018] In order to further understand the invention content, characteristics and effects of the present invention, the following embodiments are enumerated hereby, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0019] see Figure 1 to Figure 5 , an aluminum alloy space grid structure plate rib joint, including two upper and lower aluminum cover plates 2 arranged parallel to each other and at least two H-shaped aluminum rods 1 fixed between them through the first bolt 3, in the relative An H-shaped aluminum vertical rib 6 is arranged between two adjacent H-shaped aluminum rods 1, and the upper and lower ends of the H-shaped aluminum vertical rib 6 are respectively connected to the corresponding aluminum cover by the second bolt 7. Board 2 is fixed. The setting of the H-shaped aluminum vertical ribs 6 can improve the out-of-plane stiffness of the nodes.

[0020] In this embodiment, in order to improve the in-plane rigidity of the join...

Abstract

The invention discloses an aluminum alloy space grid structure slab rib node. The aluminum alloy space grid structure slab rib node comprises two aluminum cover plates arranged up and down in parallel and at least two H-type aluminum rod pieces fixedly connected between the two aluminum cover plates through first bolts. an H-type vertical aluminum rib slab is arranged between every two adjacent H-type aluminum rod pieces, and the upper ends and the lower ends of the H-type vertical aluminum rib slabs are fixedly connected with corresponding aluminum cover plates through second bolts. According to the aluminum alloy space grid structure slab rib node, because annular rib slabs and vertical rib slabs are additionally arranged on an existing cover plate node, the internal rigidity and the external rigidity of a node plane are increased. The node distinctly bears force, the rigidity and bearing capacity of the aluminum alloy grid node can be improved, the performance of aluminum alloy is improved, some potential safety hazards can be avoided, and the safety of the aluminum alloy structure can be guaranteed.

Description

technical field [0001] The invention relates to a grid structure node, in particular to an aluminum alloy space grid structure plate rib node. Background technique [0002] Due to its strong adaptability to various planar buildings, the spatial grid structure has developed rapidly in my country in recent years, such as Tianjin Museum, National Grand Theater, Shanghai Cultural Plaza, 2008 Beijing Olympic Stadium and gymnasiums all over the country There are no less than thousands of projects such as exhibition halls and exhibition halls. With the development of society, people gradually realize the unique advantages of aluminum alloy such as light weight and corrosion resistance, and aluminum alloy begins to shine on the stage of large-span space structure design. [0003] Since the 1940s, aluminum alloys have been widely used in building structures. At present, more than 7,000 aluminum alloy space structures have been built in the world. As early as 1954, the UK built an al...
