Self-driven pin lock prestressed connecting structure and connecting method

Abstract

The invention provides a self-driven pin lock prestressed connecting structure and connecting method. The self-driven pin lock prestressed connecting structure comprises an inserting structure formed by a plug pin part and a locking part. Lock catches are arranged at the locking part; the plug pin part comprises a pin tube and a piston; the side wall of the piston slips in a mode of being attached to the inner side wall of the pin tube; a stepped-shaft-shaped plug pin end is arranged at one end of the piston, and the end face of the other end of the piston and the inner wall of the pin tube jointly enclose to be a first thrust cavity; the end, adjacent to the plug pin end of the piston, of the pin tube is open; a clamping ring is arranged at the opening end of the pin tube; when the plug pin end penetrates out from a clamping ring hole and stretches between the lock catches of the locking part, the plug pin end is fixed with the lock catches; the large diameter part of a stepped shaft of the plug pin end is attached to the clamping ring hole; the large diameter part of the stepped shaft, the inner wall of the pin tube and the clamping ring jointly enclose to be a second thrust cavity; a pressing stress grouting hole is formed in the side wall of the first thrust cavity; and a pulling stress grouting hole is formed in the side wall of the second thrust cavity. The economic prestressed connecting structure can be achieved rapidly and conveniently in an inserted connection mode.

Description

technical field [0001] The invention relates to the field of building components, in particular to a self-driven pin lock prestressed connection structure and a connection method. Background technique [0002] In recent years, the plug-in structure has been applied in the connection of building components. This structure has the advantages of no need for welding and easy implementation. However, if the structure needs to be prestressed, more processes and equipment are required to realize it, so that the plug-in structure A certain amount of cost needs to be invested in prestressing treatment. How to realize a convenient and economical prestressed plug-in structure is a research direction. Contents of the invention [0003] The invention proposes a self-driven pin lock prestressed connection structure and connection method, which can quickly and conveniently realize a more economical prestressed connection structure in a plug-in manner. [0004] The present invention adop...
