Problems solved by technology

[0002] In building construction, butt jointing of concrete piles is an essential process. The traditional way of butt jointing of concrete piles is welding of steel plates, and meshing connectors are used to enhance the pullout resistance. The tensile strength of such connectors cannot meet the requirements and the connectors It is prone to damage and cause connection failure. This method is complex in construction and has poor anti-corrosion performance, and this kind of connection cannot solve the problem of sealing, resulting in poor corrosion resistance.
Patent [2010102984420] discloses a butt joint method of concrete prefabricated components composed of prefabricated component connectors. The prefabricated component connectors disclosed in this patent are not tightly bonded after butt joint, have poor pull-out resistance, have many parts, and the assembly process is relatively complicated. Complicated. In addition, the two sleeves of the joint have different structures, and there are requirements for the butt direction of the concrete pile, which brings inconvenience to the butt joint

Embodiment 1

[0035] Embodiment 1 Prefabricated Concrete Pile Quick Joint Cooperating with Steel Rod

[0036] Such as Figure 1-4 As shown, a quick connector for prefabricated concrete piles includes a tension positioning sleeve I1 and a tension positioning sleeve II2. Both the tension positioning sleeve I1 and the tension positioning sleeve II2 are sleeve-shaped structures. The tension positioning sleeve The bottoms of I1 and the tensioning positioning sleeve II2 are provided with a limit end 11 capable of limiting the end of the steel bar inside, and also include a guide buckle 3 and a spring buckle pin 4. The tensioning positioning sleeve I1 is equipped with a There is an internal thread, the guide buckle 3 is a cylindrical ring, and the outside of the guide buckle 3 is provided with an external thread that matches the internal thread of the tensioning positioning sleeve I1; the internal thread of the tensioning positioning sleeve II2 is provided. The spring reverse buckle pin 4 include...

Embodiment 2

[0042] Embodiment 2 Prefabricated Concrete Pile Quick Connector Cooperating with Rebar

[0043] Such as Figure 5 As shown, the difference between this embodiment and the first embodiment is that the bottoms of the tensioning positioning sleeve I1 and the tensioning positioning sleeve II2 are provided with threaded through holes to form a limit end, and the ends of the rebar are provided with external threads, and Screw into the threaded through hole. Other structures and principles are the same as those in Embodiment 1.

Embodiment 3

[0044] Embodiment 3 Prefabricated Concrete Pile Quick Connect Cooperating with Steel Strand

[0045] Such as Figure 6 As shown, the difference between this embodiment and Embodiment 1 is: the limiting end of this embodiment is a tapered hole with a large mouth facing inward, and a steel strand anchor head with a tapered outer surface is arranged in the tapered hole 5. The outer surface of the steel strand anchor head 5 fits with the tapered hole, the steel strand anchor head 5 is limited in the tapered hole, and the steel strand anchor head 5 is provided with a steel wire retaining spring 6, the steel strand anchor The head 5 is set and fixed on the end of the steel strand to realize the connection between the steel strand and the tension positioning sleeve I1 and the steel strand and the tension positioning sleeve II2. Other structures and principles of this embodiment are the same as those of Embodiment 1.

Abstract

The invention discloses a rapid joint of a precast concrete pile. The rapid joint comprises a stretching positioning sleeve I and a stretching positioning sleeve II which are both of a sleeve shaped structure; limiting ends for limiting end heads of steel bars inside are arranged at the bottom parts of the stretching positioning sleeve I and the stretching positioning sleeve II. The rapid joint further comprises a guide clamp and a reverse spring buckling pin; the guide clamp is in threaded fitting with the stretching positioning sleeve I; the reverse spring buckling pin comprises a screwing base, and at least three reverse buckling teeth fixed on the screwing base, wherein the reverse buckling teeth are extruded to pass through the guide clamp and then sprung back to be limited on the guide clamp; the screwing base is in threaded fitting with the stretching positioning sleeve II. The rapid joint is high in strength, simple to assemble and abut, free of damage on a connecting part body, flexible to abut, high in sealing after abutting, and high in stretching resistance and corrosion resistance.
