Abstract

The invention discloses a device and a method for adjusting a joint installation error during connection of a straight-thread sleeve pipe and a reinforcement cage. The device comprises a jack and an oil pump which is connected with an oil inlet and an oil outlet of the jack through oil pipes; the device also comprises an upper support and a lower support; the upper support is fixedly connected with a piston rod base plate of the jack, and the lower support is fixedly connected with a base of the jack; and hoops are arranged on both the upper support and the lower support and matched with diameters of main reinforcing bars of the reinforcement cage. According to the device and the method, under the condition that an original structure of the reinforcement cage is not damaged, the installation error of the reinforcement cage can be effectively overcome, so that the butt joint of the reinforcement cage can be smoothly performed, and the installation time is shortened.

Description

technical field [0001] The invention relates to an adjusting device for a steel cage, in particular to a device and method for adjusting the installation error of a steel cage joint connected by a straight thread casing. Background technique [0002] The reinforcement cages of the entire ground connecting wall and pile foundation are generally processed into several sections. After the pile foundation is formed into holes or the ground connecting wall is formed into grooves, they are installed and formed in the holes or grooves one by one. In order to ensure the construction quality, some important reinforcement cages are usually Connect with straight thread bushing. Reinforcement cages made by manual and automatic forming machines all have processing errors to varying degrees. When the errors exceed the standard, it will affect the butt joint installation of the reinforcement cages in the holes or grooves, reducing the working efficiency. The steel cage is a flexible objec...
