Concrete pile with connecting mechanisms

Abstract

A concrete pile with connecting mechanisms comprises an upper connecting mechanism and a lower connecting mechanism which are symmetrically arranged, and is characterized in that the upper connecting mechanism, as well as the lower connecting mechanism, comprises a rectangular steel end plate, angle iron welded with four corners of the steel end plate symmetrically and vertically and provided with outward corner mouths, connection steel plates welded with the inner sides of the two ends of the angle iron in a parallel and level manner, two U-shaped reinforcing steel bars transversely welded with two ends in the middle of the upper surfaces of the steel end plates and provided with upward openings, and a U-shaped reinforcing steel bar longitudinally welded with the steel end plate between the two transverse U-shaped reinforcing steel bars and provided with an upward opening, as well as angle iron capping steel plates welded with the end surfaces of the angle iron, wherein the rectangular steel end plates of both the upper connecting mechanism and the lower connecting mechanism are the same; bolt holes are formed at four corners of each steel end plate; the end parts of the U-shaped reinforcing steel bars and main reinforcing steel bars of the concrete pile are correspondingly in lap joint; and the upper connecting mechanism and the lower connecting mechanism are poured into the upper end and the lower end of the concrete pile main body through concrete.

Description

technical field [0001] The invention is a concrete pile with its own connection mechanism, which can be used in the construction of prefabricated concrete square piles at home and abroad, that is, the construction is simple and fast, and can ensure various performance indicators of the foundation pile, and can effectively promote the construction of the pile connection progress and reduce construction costs. Background technique [0002] In large civil buildings and complex industrial buildings, prefabricated piles are more and more widely used. The pile length designed by engineering technicians according to the load size and geological conditions is usually different from the length of the prefabricated pile processed by the factory, and the prefabricated pile needs to be connected to the pile. The lengthening methods of prefabricated piles include welding method, flange connection, and slurry anchor method, and the welding method is the most widely used method at present...

AI Technical Summary

Problems solved by technology

The traditional pile connection method is easy to cause loosening and cracking at the pile connection after hammering. In order to avoid loosening and cracking at the pile connection after hammering, the construction quality and project progress cannot be guaranteed.
