Embodiment Construction

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] Such as figure 1 with image 3 As shown, a tension nut sinking type prefabricated pile includes a pile body 10, the cross section of the pile body 10 is not limited, it can be a circle, a direction, a regular polygon, etc., and the pile body 10 is provided with a reinforcement cage 20 The reinforcing cage 20 includes several longitudinal reinforcing bars 21 and transverse reinforcing bars 22 fixedly connected to the longitudinal reinforcing bars 21. Preferably, the transverse reinforcing bars 22 are helically wound on the surface of the longitudinal reinforcing bars 21 to form the reinforcing bar 20. The pile The two ends of the body 10 are respectively fixed with a number of one-to-one corresponding tension nuts 30 so that the two ends of each longitudinal steel bar 21 are respectively tensioned with a tension nut 30, and the...

Abstract

The invention belongs to the technical field of construction industry precast parts and relates to a tightened nut sinking type precast pile. The technical problem that nuts used in the prior art for connection are easily damaged is solved. The precast pile comprises a pile body, wherein a steel bar cage is arranged in the pile body, and the steel bar cage comprises a plurality of longitudinal steel bars and spiral steel bars fixedly connected with the longitudinal steel bars; a plurality of tightened nuts are separately fixedly arranged at the two ends of the pile body in a one-to-one correspondence manner, and the two ends of each longitudinal steel bar are separately tightened by one tightened nut; and the tightened nuts sink into the inner part of the pile body, thereby forming a horn-shaped connecting opening between the end parts of the tightened nuts and the end part of the pipe body. As the tightened nuts sink into the pile body, the nuts cannot be easily damaged, and the connecting success rate is increased.

Description

[0001] This application is a divisional application of "Tension Nut Sinking Type Prefabricated Pile (Application No.: 201510313980.5; Application Date: 2015.06.09)". technical field [0002] The invention belongs to the technical field of prefabricated parts in the construction industry, and relates to a prefabricated pile, in particular to a tension nut sinking type prefabricated pile. Background technique [0003] Due to the relatively poor quality stability of immersed tube piles, prefabricated prestressed concrete piles have developed rapidly in recent years. In the piling process, piles of different lengths should be selected according to different needs, which requires the piles to be connected to each other to form a longer pile body. [0004] The existing piles are connected by setting metal end plates at both ends of the piles. When two piles need to be connected, they are connected by welding the end plates of the two piles. The welding work is time-consuming and l...
