[0002] Concrete structure is a structure made of cement, sand, stone, and water as the main materials, supplemented by other types of materials. It includes many types, such as plain concrete structure, reinforced concrete structure, steel-concrete structure, steel tube concrete structure and prestressed concrete structure. This structure has good durability and fire resistance, good integrity and strong moldability. It can increase its integrity through internal steel bars and other materials, and is used for earthquake resistance, explosion resistance and other purposes. The stress warning device of concrete structure is a system designed for monitoring and warning the safety status of reinforced concrete structure. The device monitors the stress state of concrete structure in real time, timely discovers and warns of potential safety hazards, thereby effectively reducing the risk of structural failure.

[0012] Beneficial effects of the utility model:

[0013] 1. Compared with the traditional stress warning device of concrete structure, it can usually only be used to detect the stress condition of a fixed position of the concrete structure, which is not convenient for comprehensive analysis of the stress condition in multiple directions, and the buried point arrangement is single, resulting in insufficient accuracy of the detection result. By setting the first detection component, the second detection component, the third detection component and the fourth detection component, the stress condition of different parts of the concrete structure can be detected respectively, so that the detection is more comprehensive, and by setting the data processing component, the detection data can be summarized and analyzed, so that the detection result is more accurate. By relatively setting two sets of first detection components at the lower end of the beam, it can be used to detect the stress condition of the beam at The displacement changes of its surface during the stress process, so that the stress condition can be analyzed according to the displacement changes of the wall surface, and the third detection component can be embedded in the interior of the beam to detect the strain changes of the beam during the stress process, and the second detection component can be set on the inner side of the second wall to detect the acceleration changes of the surface of the second wall during the stress process, and the first connection line, the second connection line and the third connection line are set to be electrically connected with the data processing component so that the first detection component, the second detection component and the third detection component can transmit the detected strain, displacement and acceleration change information of the concrete structure during the stress process to the data processing component.

[0014] 2. By setting up the data processing component, the received detection data of the first detection component, the second detection component and the third detection component can be summarized and analyzed, so as to make a reasonable judgment. When the analysis shows that the force change is abnormal, the alarm light on the top of the data processing module will flash to warn, and the speakers on the left and right ends of the data processing module will sound an alarm to remind that a certain position of the concrete structure is abnormal. The staff will deal with the corresponding position according to the alarm to avoid accidents. By relatively setting two groups of fourth detection components at the left and right ends of the load-bearing column, the force condition of the load-bearing column can be separately detected. By setting up the second accelerometer module, the acceleration change of the load-bearing column during the force process can be detected. When the acceleration is abnormal, the display module will sound an alarm and display the abnormal problem. With the mutual cooperation of various components, the concrete structure can be subjected to force detection from multiple directions and angles, so that the detection effect is better and the early warning is safer and more reliable.
