Problems solved by technology

[0005] At present, the connection methods between H-shaped steel are mainly bolted connection, welding and rivet connection. Among them, the bolted connection and rivet connection have the advantages of convenient installation and detachment, but the connection strength is poor, and the pressure bearing time is too long or pressure If it is too large, it may lead to loosening, and then there is a risk of unstable connection or even disconnection; while welding has high connection strength, but welding is time-consuming and laborious, and it is difficult to disassemble and recycle. At the same time, welding is not conducive to the transmission of stress. Partition phenomenon is easy to appear on the welding surface, which will affect the connection strength of the welding surface. Therefore, a connection joint with high connection strength and detachable recycling is urgently needed in steel structure engineering.

Abstract

The invention discloses a self-adaptive steel structure connecting joint and a connecting method thereof and belongs to the technical field of steel structures. According to the self-adaptive steel structure connecting joint, a fourth connecting mode of H-shaped steel can be provided, the high-strength connecting joint is adopted for performing wrapping connection on the H-shaped steel, the H-shaped steel is connected conveniently in a high-temperature phase shape by depending on an enhanced double-way memory effect of a shape memory alloy, the H-shaped steel can be effectively retained and abutted in a low-temperature phase shape, and expansion connection between a pair of H-shaped steel and the connecting joint is achieved; meanwhile, specially-treated positioning rods are arranged for auxiliary purposes, and the positioning rods have the function of indirectly detecting H-shaped steel stress transmission while having the function of positioning the H-shaped steel; and on the one hand, the strength of connecting between the H-shaped steel can be remarkably improved, on the other hand, stress transmission between the H-shaped steel and non-normal detection are facilitated, and technicians can timely perform reinforcing and strengthening.

Description

technical field [0001] The invention relates to the technical field of steel structures, and more specifically relates to an adaptive steel structure connection joint and a connection method thereof. Background technique [0002] Steel structure is a structure composed of steel materials, which is one of the main types of building structures. The structure is mainly composed of beam steel, steel column, steel truss and other components made of section steel and steel plate, and adopts rust removal and antirust processes such as silanization, pure manganese phosphating, washing and drying, and galvanizing. The components or components are usually connected by welds, bolts or rivets. Because of its light weight and easy construction, it is widely used in large factories, stadiums, super high-rises and other fields. [0003] Steel is characterized by high strength, light weight, good overall rigidity, and strong resistance to deformation, so it is especially suitable for buil...
