Non-welded PHC pipe pile quick connecting method and pulling-resistant quick installing structure

Abstract

The invention provides a non-welded PHC pipe pile quick connecting method and a pulling-resistant quick installing structure. The pulling-resistant quick installing structure comprises pipe pile steel bars, steel bar head sleeves and quick connectors; the quick connectors of the steel bars of a pipe pile are perpendicularly and fixedly connected to the quick connectors of the steel bars of another pipe pile in an inserted mode; the quick connectors comprise the male quick connectors and the female quick connectors, when the quick connectors are fixedly connected in an inserted mode, the male quick connectors are perpendicularly inserted into the female quick connectors from inserting openings to push out rolling balls into inserted connection fixing cavities, and the rolling balls fall to the bevels of rolling ball releasing openings; when annular grooves formed in the stepped shaft small ends of the male quick connectors arrive at the bevels of rolling ball releasing openings, the rolling balls roll into the annular grooves, the annular groove walls and the bevels of rolling ball releasing openings clamp and lock the rolling balls in the annular grooves under the gravity action of the pipe piles to form annular ball zones, the male quick connectors are fixedly hung on the female quick connectors through the annular ball zones formed on stepped shafts, and then the pipe piles are connected in a butt-joint mode through the quick connectors. According to the non-welded PHC pipe pile quick connecting method and the pulling-resistant quick installing structure, the stable high-strength non-welded pipe pile quick connecting structure can be provided in the PHC pipe pile connecting work, and corrosion and rust protection treatment is easy to conduct.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a PHC pipe pile quick-connection method without welding and a pull-out-resistant quick-installation structure. Background technique [0002] PHC pipe piles are commonly used piles in construction. During construction, when the length of the pipe piles is not enough, pile connection operations are required to realize the connection between the two pile bodies. The current pile connection operation is to add iron to the joint surface. Plates are used to complete the pile connection by welding iron plates, but due to the complex construction environment, the quality of the welding process is prone to fluctuations, making the strength of the welded structure unstable, and the process is not easy to carry out anti-corrosion and anti-rust treatment. After long-term use in a humid environment , The pile-connected iron plate is easy to rust and affects the quality of the project; ho...
