Connecting blocking thread for connecting bars of prestressed tubular pile

Abstract

The invention relates to a connecting blocking thread for connecting bars of a prestressed tubular pile, which comprises a thread insert, a lock nut, a tapered screw insert and three-claw screw threads, wherein the upper part of the thread insert is geared with and sleeved on the lock nut; the tapered screw insert is coaxially geared with and arranged in the thread insert; a square blind hole is arranged in the middle of the upper surface of the tapered screw insert; a tapered hole is arranged on the lower part of the tapered screw insert; and the radial three-claw screw threads are embedded uniformly in the tapered hole. In the blocking thread, two segments of three-claw screw threads are adopted to connect and lift the reinforcing steel bars; the connection is firm and reliable; the prestressed force of the reinforcing steel bars is connected after the pile is chopped; the intensity of the prestressed tubular pile is ensured; and the quality of a building is ensured.

Description

Technical field [0001] The invention belongs to the field of construction, and relates to prestressed pipe piles, in particular to a prestressed pipe pile connecting bar connecting wire. Background technique [0002] Pre-stressed pipe piles are construction piles that are driven directly into the ground. Due to the complex geological conditions of the underground, pipe piles of the same length cannot achieve the same depth. For pipe piles that cannot be deep, they are usually realized by cutting piles. The flush of construction piles. However, because it is a prestressed pipe pile, the consequence of the pile cutting is to destroy the prestress of the steel bar. The cutting pile of a prestressed pipe pile is generally difficult to connect the reinforcement and maintain the prestress, which makes the pipe pile unable to meet the design requirements. At present, no solution has been found to solve the above problems. [0003] Through the search, no published patent documents identi...
