Embodiment 1

[0042] like figure 1, a prefabricated pile that can be connected by steel strands, including a pile body 1, and a plurality of axial main ribs 2 are arranged in the pile body 1, and the axial main ribs 2 are steel rods or steel bars. There are also threading holes 3 for passing the steel strand, and the threading holes 3 pass through both ends of the pile body 1 along the axial direction of the pile body 1 . As we all know, the shear resistance of steel strands is stronger than that of steel rods. Therefore, when several piles 1 need to be connected to each other in the axial direction, the steel strands can pass from one pile to another pile 1, and then pass through them in turn. All the piles 1 that need to be connected, if the pile 1 is a pile with an end plate, the structure of the end plate can refer to a patented pipe pile end plate [application number: 201420690572.2], then the two piles 1 can pass through The end plates are welded and fixed first, and then the steel s...

Embodiment 2

[0052] An axial connection method for prefabricated piles, comprising the following steps:

[0053] A. Material preparation: prepare the prefabricated piles that need to be connected axially. The prefabricated piles include a pile body 1. The pile body 1 is provided with a number of axial main ribs 2, and the pile body 1 is also provided with The threading hole 3 of the steel strand is pierced and the threading hole 3 penetrates both ends of the pile body 1 along the axial direction of the pile body 1,

[0054] B. Bottom pile threading: Take a prefabricated pile and thread the steel strand into the threading hole 3. One end of the steel strand is fixedly connected to the bottom of the pile body 1, and the other end is passed through the threading hole 3. The length of the prefabricated pile is greater than the total length of the pile to be connected, and the prefabricated pile is driven into a suitable position underground.

[0055] C. Pile connection: Pass the steel strand ...

Abstract

The invention belongs to the technical field of buildings, and relates to a precast pile capable of using steel strands for connection and a connection method. The precast pile comprises a pile body, a plurality of axial main ribs are arranged in the pile body, threading holes used for allowing the steel strands to penetrate are formed in the pile body, and the threading holes penetrate the two ends of the pile body in the axial direction of the pile body; and the anti-bending performance of the connection pile can be improved, and the strength of the whole connection pile can be improved.

Description

technical field [0001] The invention belongs to the technical field of construction, and relates to a prefabricated pile which can be connected by steel strands and a connection method. Background technique [0002] Prefabricated piles are various materials and various forms of piles made in factories or construction sites, such as wood piles, concrete square piles, prestressed concrete pipe piles, steel piles, etc. Or vibrate into the ground. The precast piles used more in the construction field in China are mainly concrete precast piles and steel piles. Concrete prefabricated piles can withstand large loads, are strong and durable, and have fast construction speed. They are one of the widely used pile types. [0003] In the existing prefabricated piles, there are usually axial main bars, which can be steel rods, steel bars or steel strands. The performance and shear resistance are good. The main axial reinforcement of the existing prefabricated piles is fixed inside the...
