So set up, annular lug 211 can homogenize prestressing force for the prestressing force that the steel reinforcement cage can bear when prestretching is carried out is bigger, prevents that first embedded component 210 or second embedded component 220 from damaging.

In one embodiment, the outer diameter of the annular protrusion 211 gradually decreases from the end of the first fastener element 210 and/or the second fastener element 220 to the middle.

With such an arrangement, the annular bump 211 can further homogenize the prestress, and the phenomenon of abrupt change of the angle of the outer wall surface (such as two mutually perpendicular surfaces) does not exist, so that the prestress loss can be prevented.

It is understood that in other embodiments, the annular protrusion 211 with other shapes, such as rectangular or trapezoidal annular protrusion 211 with a cross section in the axial direction, may be used.

Referring to fig. 11, fig. 11 is a cross-sectional view of a precast pile 300 according to an embodiment of the present invention.

The precast pile 300 is manufactured by arranging the steel bars 310 according to the stress requirement after forming to form a steel bar cage, pre-stretching the steel bar cage to generate prestress to offset or reduce the tensile stress generated by external load, so that no crack is generated or the time for generating the crack is prolonged under the condition of normal use of the steel bars 310; the reinforcement cage is placed into a mold after being formed, then concrete 320 is poured into the mold, a centrifugal mode is started if a hollow precast pile 300 needs to be made, the precast pile is placed in the mold in a standing mode if an entity pile needs to be made, and the precast pile 300 is formed after drying and demolding after being formed. The pile manufacturing method is simple, and the manufactured precast pile 300 is high in strength, flexible in construction site and low in cost.

The precast pile 300 is connected by opposing the reinforcing bars 310 connected to the first pre-embedded elements 210 to the reinforcing bars 310 connected to the second pre-embedded elements 220 and using the quick coupling assembly 100 when connecting two precast piles 300.

Preferably, the steel bar 310 is a steel bar for prestressed concrete 320. The PC steel bar has the advantages of high strength and toughness, low looseness, strong bond force with the concrete 320, good weldability and upsetting property, material saving and the like.

It is understood that in other embodiments, other types of rebar 310 are possible, such as stainless steel rods, hot rolled steel rods, medium strength pre-stressed wires, stress-relief wires, steel strands, pre-stressed rebar 310, and the like.

In an embodiment of the present invention, the reinforcing bars 310, the first embedded elements 210 and the second embedded elements 220 are all pre-embedded into the concrete 320 in advance to become embedded elements.

It is understood that in other embodiments, the first embedded element 210 and the second embedded element 220 can be connected with the steel bar at a later stage. The operation steps are that the concrete 320 at the end of the precast pile 300 is chiseled to expose the steel bar, and then the first embedded element 210 or the second embedded element 220 is connected to the end of the steel bar 310.

In an embodiment of the present invention, the precast pile 300 is a hollow tubular pile.

In one embodiment, the reinforcement cage is subjected to a tensioning step and a relaxation step. The tensioning step is to apply prestress to the reinforcement cage in advance so that the reinforcement cage bears compressive stress and further generates certain deformation to improve the load which can be borne by the reinforcement cage, wherein the load comprises the self weight of a component, wind load, snow load, earthquake load action and the like; because the prestress applied in the tensioning step is larger, in order to reduce the prestress loss of the reinforcement cage, the tensioning step is required.
