Aluminum alloy plate node shear connecting structure and connecting method thereof

Abstract

The invention relates to an aluminum alloy plate node shear connecting structure and a connecting method of the structure. The shear connecting structure comprises an upper cover plate, a lower coverplate, a plurality of connecting rod pieces and a plurality of fasteners, wherein the connecting rod pieces are fixed on the upper cover plate and the lower cover plate through the fasteners; a reinforcing rod piece is vertically arranged between the upper cover plate and the lower cover plate; the upper cover plate is horizontally arranged at the top end of the reinforcing rod piece; the lower cover plate is horizontally arranged at the lower end of the reinforcing rod piece; a center line of the reinforcing rod piece in a length direction is coincided with center lines of the upper cover plate and the lower cover plate; and the centers of the upper cover plate and the lower cover plate are connected with the reinforcing rod piece in a fastening manner. Compared with the traditional aluminum alloy plate node, the vertical shear capacity of the connecting structure can be improved by several times, aluminum alloy sections are saved, and the connecting structure is convenient in construction.

Description

technical field [0001] The invention relates to a connection node, in particular to an aluminum alloy plate type node shear resistance connection structure and a connection method thereof. Background technique [0002] The connection methods of aluminum alloy grid structure mainly include plate joints (also known as TEMCOR joints), bolt ball joints, cast aluminum joints and hub joints (also known as embedded joints). During the processing of aluminum alloy materials, the processing cost of aluminum alloy rods with I-shaped cross-section is relatively low, so the combination of plate nodes and aluminum alloy rods with I-shaped cross-section is commonly used for structural design. However, due to the insufficient shear performance of the web of the I-shaped cross-section aluminum alloy member, the web is prone to local buckling, especially when the member is subjected to axial tension. Therefore, how to realize a simple, effective, and high-bearing-capacity slab-type joint co...

AI Technical Summary

Problems solved by technology

The end of the I-shaped bar of the aluminum alloy column-plate joint structure of the invention is welded with a connecting plate, and a hollow hexagonal column is used in the middle, and the six connecting plates are connected with bolts, which has the following defects: complex construction, inconvenient installation, and The precision requirement is high, large errors are not allowed, and the practicability is not strong; the hollow hexagonal prism is used, and the hexagonal prism must withstand the end plate of the rod, which requires a larger size of the hexagonal prism, which is more consumable and increases the quality of the joints
