Problems solved by technology
Steel pipe columns or outrigger trusses are usually constructed ahead of the ground floor. They are generally in a cantilevered state and are operated in the air. It is not easy for inspectors to inspect nearby. They need to use professional ladders or set up temporary operating platforms, which is not only time-consuming but also dangerous in the working environment.

The invention discloses a concrete-filled steel tube compactness detection system, which comprises an infrared thermal imager, an image processing module, a data processing module and a display, wherein the infrared thermal imager is used for shooting an infrared thermogram of a to-be-detected concrete-filled steel tube; the image processing module is used for carrying out image processing on theinfrared thermogram shot by the infrared thermal imager and sending the processed image to the data processing module; the data processing module is used for analyzing the processed image, finding outthe position of the image with abnormal temperature, judging the position point of the concrete compactness defect according to the position of the image with abnormal temperature, and marking the position point; and the display is used for displaying the processed image and displaying the position point of the concrete compactness defect. The infrared thermogram of the to-be-detected concrete-filled steel tube is acquired by the infrared thermal imager, and the infrared thermogram is processed and analyzed, so that the position point of the compactness defect of the concrete can be accurately determined.
Description
technical field [0001] The invention relates to the technical field of building construction, in particular to a system and method for detecting the compactness of steel pipe concrete. Background technique [0002] There are often multi-layer stiffeners in steel tube concrete members. In super high-rise buildings, steel tube concrete is often used in columns and outrigger trusses. Whether it is a steel pipe column or an outrigger truss, it often has a certain inclination angle, which brings great difficulties to determine the concrete pouring process and ensure the compactness of the concrete after pouring. [0003] In the pouring of concrete filled steel tubes, three construction techniques are generally used: the high-level drop-free vibration-free method uses the kinetic energy generated when the concrete falls to achieve the purpose of vibrating the concrete, that is, the concrete is dropped in the air, and the free fall height is required to be more than 4 meters. .
