Experiment apparatus for observing generation and development of concrete cracks

Abstract

The invention discloses an experiment apparatus for observing the generation and the development of concrete cracks. The apparatus is used for real-time omnibearing observation and recording of the generation and development of the concrete cracks to provide guidance application of practical engineering. A technical scheme adopted in the invention is characterized in that the apparatus comprises a reaction frame (1) arranged in a frame structure, a bearer sample loading platform (6) for fixing a test beam member (5) is arranged n the reaction frame (1), the upper end and the lower end of the bearer sample loading platform (6) are respectively provided with a hydraulic device for applying pressure to the test beam member (5), the upper beam and the lower beam of the bearer sample loading platform (6) are respectively provided with a sliding rail (3), the hydraulic device can move along the sliding rail (3), the bearer sample loading platform (6) is provided with a camera (4) capable of monitoring the generation and development process of the cracks, the camera (4) is connected to a computer (11), and the bearer sample loading platform (6) is provided with a lime brush (9) and a lime bucket (10).

Description

technical field [0001] The invention relates to the technical field of concrete testing, in particular to an experimental device for observing the occurrence and development of concrete cracks. Background technique [0002] Cracks in concrete components under the action of external force are often the beginning of concrete component damage. Therefore, it is of great application value to observe the occurrence and development of cracks in concrete components. At present, most of the instruments and methods for observing the occurrence and development of concrete cracks require a lot of manpower and the methods are controversial, and it is basically difficult to realize real-time and all-round crack observation and recording, so the observed crack data are mostly the end of the final development. For the process data, there are few records, and some parts of the components are generally observed and recorded, so it is difficult to fully reflect the whole process of crack devel...

At present, most of the instruments and methods for observing the occurrence and development of concrete cracks require a lot of manpower and the methods are controversial, and it is basically difficult to realize real-time and all-round crack observation and recording, so the observed crack data are mostly the end of the final development. For the process data, there are few records, and some parts of the components are generally observed and recorded, so it is difficult to fully reflect the whole process of crack development and development of concrete components.

The known methods and instruments for observing concrete cracks are generally artificially timed to take photographs or records to realize the development of concrete member cracks, but in some cases, especially in time-consuming experiments, it is difficult to record and observe the entire development of cracks in real time process, cannot truly reflect the characteristics of the occurrence and development of concrete cracks
