Concrete-filled steel tubular column compactness testing tool

Abstract

The invention discloses a tool for detecting the compactness of a steel pipe concrete column, which comprises a fixing ring sleeved on the concrete column, a tensioning frame and a U-shaped fixing frame are fixed on the fixing ring, and the tensioning frame is mounted on A tensioning component is provided, and a height-fixing component is provided on the fixed frame; two permanent magnet plates with opposite poles and parallel are provided on the fixed frame, and a sound test is connected in the fixed frame by a pin shaft rotation The hammer; the tensioning assembly includes a slide bar that is slidably connected to the tensioning frame. The advantage is that the electromagnetic coil generates current during the downward swing of the sound hammer to make the soft capsule column hard and prevent the sound hammer from swinging down, and soften the sound hammer to continue to swing down after the sound hammer is completely stationary, realizing the test The automatic control of the swing position of the hammer avoids the time-consuming and labor-intensive manual control every time, and avoids the safety hazards caused by the staff when climbing high without manual operation.

Description

technical field [0001] The invention relates to the technical field of concrete detection, in particular to a test tool for the compactness of a concrete-filled steel tube column. Background technique [0002] At present, there are generally three common methods for testing the compactness of CFST columns: [0003] The first is: core drilling method, that is, drilling cores on the formed concrete-filled steel tubular columns, and judging the quality of the concrete in the column cores by the quality of the core samples drilled. The core drilling method cannot comprehensively judge the quality of the entire concrete column. The quality situation is relatively limited, and there is a risk of destroying the integrity of the concrete column, which will weaken the force of the concrete column in severe cases; in addition, the core drilling method has a long period of time, high cost, and is not easy to erect on the steel tube concrete column. Core drilling equipment and other di...
