Abstract

The invention involves a kind of tube column to meet the buckle, as well as uses with the time mouth constitution pre-stressed high strength pre- workpiece and -odd in view of the fact that with the between between connection structure and the connection method, is the pre- workpiece to meet buckles with the pre- workpiece manufacture domain. On under the spiral goes against pile extension buckles by pulls the cap nut, inflates the screw and goes against pulls the cap nut constitution, pulls the cap nut screw together in the spiral which inflates the screw wire shorts, inflates the screw the inflation measure expansion in to go against pulls in the cap nut in the inflation cavity, when pile extension, demands the collection attire two maybe certain to pull the cap nut with the between nose minute to buckle goes against pulls the cap nut mouth which corresponds with the prefabrication, inflates the screw the spiral wire shorts screw together in pulls the cap nut screw thread in, Inflates the screw the inflation to carefully examine like goes against pulls the cap nut the inflation cavity also the inflation sells under the function in its nose to inflate in goes against pulls the cap nut in the inflation cavity, completes docking between the pre- workpiece and pre- workpiece.
