Cast-in-place concrete pile reinforcement cage barbed floating prevention device and application method thereof

Abstract

The invention provides a cast-in-place concrete pile reinforcement cage barbed floating prevention device. The floating prevention device comprises a base, barbs, springs and limiting stop dogs, wherein the base is fixed to the outer sidewall of a reinforcement cage; one end of each barb is rotatably connected to one end of the base; the springs are used for forming pretightening force between thebarbs and the base; the limiting stop dogs are fixed to the upper surface of the base; one end of each limiting stop dog abuts against the upper surface of the corresponding barb and is used for limiting the extreme position of the barb in the rotating process. According to the floating prevention device, the barbs and the base are connected through hinges and the springs to enable the barbs andthe base to be closed and opened; when the barbs and the base are in an opened state, the reinforcement cage can be dropped and lifted up conveniently; when the barbs and the base are in a closed state, the tip ends of the barbs can firmly grasp the hole wall, and the floating prevention effect is good; during pouring of concrete, the cast-in-place concrete pile reinforcement cage barbed floatingprevention device can prevent the reinforcement cage from floating without additional staff and devices.

Description

technical field [0001] The invention belongs to the field of construction engineering and relates to the construction field of pile foundation reinforcement cage anti-floating treatment, in particular to a barb-type anti-floating device for reinforcement cages of concrete pouring piles and a use method thereof. Background technique [0002] Since the reform and opening up, my country's social economy has developed by leaps and bounds, science and technology have also been continuously improved, and the development of my country's construction industry is also booming. Due to the improvement of people's quality of life, the requirements for buildings are getting higher and higher. In order to meet people's requirements, construction units continue to strengthen their own development, improve the quality of building construction, and ensure the stability and safety of buildings after they are put into use. . Due to the simple construction technology of reinforced concrete cas...

Problems solved by technology

[0009] The object of the present invention is to provide a barb-type anti-floating device and method of use for concrete cast-in-situ piles, so as to at least solve the problem that the steel cages are affected by the rising impact force and buoyancy of the concrete during the concrete pouring process of the current reinforced concrete cast-in-place piles. Phenomena, resulting in poor pile quality, displacement of steel cages, long leaking steel bars, serious waste of steel bars, and even lead to the problem of waste piles
