Description

Technical Field

[0001] The utility model relates to the technical field of steel cage installation, in particular to a steel pipe pile steel cage clamp and a steel pipe pile system. Background Art

[0002] Currently, during the installation of steel pipe piles, in order to prevent the steel cage inside the steel pipe pile from touching the bottom, it is generally necessary to set a bracket on the upper part of the steel pipe to fix the upper position of the steel cage by hanging or clamping to prevent the steel cage from touching the bottom.

[0003] If the hanging method is used, the entire bracket will be very large, which is not conducive to construction. In addition, there are often many steel pipe piles during construction, so the cost of using the hanging method will be very high, time-consuming and labor-intensive.

[0004] If the clamping method is used, the bracket is also called a cage clamp. It clamps the main threaded steel bars on the steel cage through two steel plates, and then the whole formed by the two steel plates can be supported on the upper part of the steel pipe. It mainly relies on the friction between the steel plates and the main threaded steel bars to fix the steel cage. During use, when the steel cage is heavy as a whole (generally more than 25t), due to mechanical construction at other locations on the construction site, the construction site will be vibrated. This vibration sometimes causes the steel cage to slide a certain distance relative to the steel plate and then re-form a relatively fixed relationship (mainly affected by two factors: 1. The circumferential connecting steel bars between adjacent main threaded steel bars will limit the downward sliding of the steel cage. At this time, the steel plate will damage the circumferential connecting steel bars, causing the circumferential connecting steel bars to deform; 2. The straightness of the main threaded steel bars themselves will not be particularly small, which will also cause the steel cage to slide a certain distance relative to the steel plate and then re-form a relatively fixed relationship). In this case, the relative distance from the bottom of the steel cage to the bottom of the pile will change, thereby adversely affecting the quality control of the steel pipe pile. Summary of the Invention

[0005] The purpose of the present invention is to overcome the shortcomings in the background technology that a bracket is set on the top of the steel pipe to fix the upper position of the steel cage by hanging or clamping, and sometimes the relative distance from the bottom of the steel cage to the bottom of the pile will change, thereby bringing adverse effects on the quality control of the steel pipe pile, and provide a steel pipe pile steel cage clamp and steel pipe pile system.
