[0002] Since the quality of prefabricated components can be well guaranteed in the factory, the safety of the assembly structure mainly depends on the connection of the components and the surrounding components. Reliable connection quality can achieve the transmission of the specified internal force according to the design requirements, and will not cause problems in use and appearance. If the joint connection quality is defective, it may cause cracks, leakage and other use problems, or it may affect the force transmission between components and components, components and supporting structures, causing problems in bearing capacity and safety, and even causing structure disintegration and serious consequences such as collapse. The investigation of the damage of each earthquake found that the damage of prefabricated beam and column components was relatively light, and the main reason for the collapse was the connection damage between the components in the frame structure. The main methods of steel bar connection of prefabricated structure components in China include welding connection, mechanical connection, binding lap joint, sleeve grouting connection, and restrained plate anchor connection.

However, the stability of the steel sleeve after installation is insufficient, which reduces the safety of the steel sleeve and easily causes harm to the operator, and has safety hazards. Therefore, we propose a high-stability steel sleeve for high-ductility concrete. UTILITY MODEL CONTENTS
