Embodiment Construction
[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0023] The object of the present invention is to provide a connecting plate reinforced aluminum alloy node that can resist bending moment and shear force, which can ensure the necessary bending and shearing bearing capacity and stiffness in the node area, so that it can be applied to Moment and shear force of aluminum alloy structure, expanding the scope of application of aluminum alloy structure.
[0024] In order to make the above objects, features and advan...

The invention discloses a reinforced aluminum alloy joint for connecting plates. The reinforced aluminum alloy joint for the connecting plates comprises an aluminum alloy joint plate, a plurality of I-shaped aluminum alloy rod pieces and the connecting plates. The aluminum alloy joint plate is connected with flange plates of the I-shaped aluminum alloy rod pieces, and web plates of the I-shaped aluminum alloy rod pieces are connected through the connecting plates. The connecting plates comprise first connecting plates and second connecting plates, through holes are formed in the first connecting plates, the first connecting plates are connected with web plates of a pair of I-shaped aluminum alloy rod pieces on the same axis, the second connecting plates pass through the through holes in the first connecting plates, and the second connecting plates are connected with web plates of a pair of I-shaped aluminum alloy rod pieces on other axes. According to the reinforced aluminum alloy joint for the connecting plates, the webs which are originally broken in the joint area of the aluminum alloy rod pieces are connected together through the connecting plates, so that discontinuous web plates are partially continuous, the continuity of the transmission of the bending moment and shear force of the rod pieces at the joint area is guaranteed, the influence of sudden changes of the bendingstiffness and shear stiffness at the joint area on the structure is avoided, and the application range of the aluminum alloy joint can be extended.
Description
technical field [0001] The invention relates to the technical field of building nodes, in particular to a connecting plate reinforced aluminum alloy node. Background technique [0002] The aluminum alloy joints used in my country's current "Code for Design of Aluminum Alloy Structures" (GB50429-2007) are disc joints, referred to as normative joints, such as figure 1 shown. In this type of joint system, the flanges of the aluminum alloy members are connected to the disc joints by bolts, and the webs of the aluminum alloy members are interrupted in the joint area. This node has the following advantages: simple structure, can effectively transmit the axial force of aluminum alloy rods, and is suitable for dome structures dominated by axial internal forces. [0003] However, due to the discontinuity of the webs of the adjacent aluminum alloy members, the above-mentioned joints are difficult to effectively transmit shear force and bending moment, so they cannot be applied to st...
