Inserting connection type single-layer aluminum alloy reticulated shell connection joint

Abstract

The invention discloses an inserting connection type single-layer aluminum alloy reticulated shell connection joint. The inserting connection type single-layer aluminum alloy reticulated shell connection joint comprises aluminum alloy rod pieces, an upper circular cover plate, a lower circular cover plate, a wedge block and shearing resisting connection plates; the wedge block is arranged betweenthe upper circular cover plate and the lower circular cover plate, and the center line of the wedge block in the length direction coincides with the center lines of the upper circular cover plate andthe lower circular cover plate; the wedge block is provided with T-shaped hole grooves in the radial pattern, and the shearing resisting connection plates are in a T shape; one end of each shearing resisting connection plate is provided with a wing edge small in width to be inserted into the corresponding hole groove of the wedge block; the shearing resisting connection plates and the wedge blockare connected in a mechanical engaging manner; the other ends of the shearing resisting connection plates and web plates of the aluminum alloy rod pieces are connected through stainless steel bolts; and upper and lower wing edges of the aluminum alloy rod pieces and the upper and lower circular cover plates are connected through stainless steel bolts. Due to the inserting connection type single-layer aluminum alloy reticulated shell connection joint, the bending resisting and shearing resisting bearing force of the joint is remarkably enhanced, the rigidity of the joint and the overall stability of a reticulated shell are improved, and therefore application to a single-layer aluminum alloy reticulated shell structure larger in span can be achieved.

Description

technical field [0001] The invention belongs to the field of civil engineering, and relates to a space grid structure node, in particular to a connection node of a single-layer aluminum alloy reticulated shell. Background technique [0002] Aluminum alloy has the advantages of low density, easy forming and high specific strength, and is widely used in aerospace, weapon industry and other fields. Due to a series of advantages such as light weight, high strength, easy processing, corrosion resistance, and beautiful appearance, the large-span aluminum alloy space structure has attracted the attention and favor of architects and structural engineers for its excellent expressiveness and applicability. The connection nodes of the single-layer aluminum alloy reticulated shell are the key components of this type of structure.

[0003] The patent "An aluminum alloy plate-type joint shear connection structure and its connection method" (application number 201810229409.9) discloses a circular stiffening member with no connection and no contact between the stiffening member and the connecting member. Aluminum alloy plate-type joint shear connection structure, although the installation of this connection structure is simpler, the construction can allow errors, and the practicability is stronger, but the bending moment and shear force borne by the transmission nodes are limited, which cannot provide for the structure. Sufficiently large bearing capacity and overall rigidity, resulting in the limitation of the structural span of the reticulated shell
