Description

Technical Field

[0001] The utility model relates to the technical field of concrete setting time detection, in particular to a concrete setting time detection device. Background Art

[0002] The embedded detection method of concrete coagulation detection usually involves burying the temperature sensor inside the concrete before pouring the concrete. After pouring the concrete, as the cement hydration reaction proceeds, heat will be released, causing the temperature inside the concrete to rise. Subsequently, as the hydration reaction gradually slows down and the heat dissipates from the concrete surface, the temperature will gradually drop. The temperature sensor embedded in the concrete can sense and record the temperature changes inside the concrete in real time. By collecting and analyzing these temperature data, the coagulation process of the concrete and its changes can be inferred. Generally speaking, when the temperature of the concrete reaches a peak and begins to drop, it can be considered that the initial coagulation stage of the concrete has ended and it has entered the final coagulation stage. Therefore, by monitoring the temperature changes, the coagulation time of the concrete can be indirectly evaluated.

[0003] During concrete pouring, depending on the height of the concrete foundation, multiple temperature sensors are usually tied and fixed to the steel bars at uniform intervals in the concrete foundation (such as Figure 6 When fixing the temperature sensor, the staff usually determines the position of the temperature sensor on the steel bar by visual inspection, which leads to errors in the distance between the temperature sensors, which may lead to errors in the measurement of the concrete setting time.
