Description
Technical Field
The invention relates to the technical field of compactness detection, in particular to a concrete filled steel tubular column compactness detection structure.
Background
At present, three common methods for detecting the compactness of the concrete filled steel tubular column are generally adopted:
the first one is: the core drilling method is that holes are drilled on a formed concrete-filled steel tubular column for core pulling, and the quality of concrete in the column core is judged according to the quality condition of a drilled core sample, so that obviously, the core drilling method can only continuously detect the quality of the concrete at a certain test point, cannot comprehensively judge the quality condition of the whole concrete column, and has large limitation; moreover, the grouting reinforcement of the drilled hole is difficult to meet the strength equal to the whole column core concrete, so that the risk of damaging the integrity of the concrete column exists, and the stress of the concrete column can be weakened in serious cases; in addition, the core drilling method has the defects of long period, high cost, difficult erection of core drilling equipment on the steel pipe concrete column and the like.
The second method is as follows: the ultrasonic method is based on the basic principle that a transmitting transducer is utilized to radiate high-frequency vibration at one end of the outer diameter of a steel pipe and transmits the high-frequency vibration to a receiving transducer at the other end of the outer diameter of the steel pipe through the center of the steel pipe, the transmission direction and the transmission path of ultrasonic waves can be changed when the ultrasonic waves meet interfaces formed by various defects in the transmission process, the energy of the ultrasonic waves can be attenuated at the defects, and the relative change of sound time, sound amplitude and frequency when the ultrasonic waves reach the receiving transducer is caused. The method is high in cost and seriously influenced by construction environment, so that the method is high in theoretical performance but low in feasibility in the actual construction process.
The third is: the knocking method is suitable for generally investigating the quality of column core concrete, completely depends on the technology and experience of technicians, and is greatly influenced by subjective factors; moreover, the knocking method lacks theoretical basis and data for archiving, and is inconvenient for construction technology management and quality detection technology management; in addition, the tapping method is difficult to accurately judge for a concrete filled steel tubular column with a large wall thickness.
Among the prior art, when using the strike method, generally adopt cell-phone or handheld recorder to beat the sound and record, just so make the strike method need a plurality of people to cooperate together and accomplish, one utilizes equipment to strike, another records, and current striking equipment can not fix on the concrete column, can influence the result that detects because the hand shakes or does not take steadily when handheld, secondly current detection device is the ring form, need follow concrete one end and remove slowly, the way returns to take off again, very inconvenient like this, the efficiency of detection has been reduced.
