Description

Technical Field

[0001] The utility model relates to the technical field of concrete construction, in particular to a temperature measuring device for large-volume concrete. Background Art

[0002] During concrete construction, the cement hydration reaction releases a large amount of heat, which causes the internal temperature of the concrete to rise. If the internal temperature of the concrete is too different from the external ambient temperature, it will cause cracks in the concrete, affecting the strength and durability of the concrete. Therefore, by measuring the temperature of the concrete, we can timely understand the changes in the internal temperature of the concrete so that we can take appropriate measures to control the temperature of the concrete and prevent the occurrence of cracks. Concrete temperature measurement usually uses temperature sensors, which are buried in different positions in the concrete to monitor the temperature changes of the concrete in real time. At the same time, computer technology can be combined to collect, process and analyze the temperature measurement data to provide a scientific basis for concrete construction.

[0003] A temperature measuring device for large-volume concrete is a device specifically designed to measure the temperature of large-volume concrete during construction and curing. In large-volume concrete, the heat of cement hydration is concentrated, and the internal temperature rises rapidly and highly. If the temperature changes inside the concrete cannot be accurately grasped, temperature stress may easily lead to cracks in the concrete and quality problems. The temperature measuring device is particularly important so that construction personnel can understand the temperature status of large-volume concrete at any time, take effective temperature control measures in a timely manner, adjust the curing method and control the pouring speed, and ensure the quality and structural safety of large-volume concrete.

[0004] In the existing temperature measuring devices used for large-volume concrete, single-point temperature measurement measures the temperature of a specific location, but the temperature distribution inside the large-volume concrete is uneven, which makes it difficult for the data of single-point temperature measurement to accurately represent the temperature conditions of the entire concrete structure. The results of single-point temperature measurement are easily affected by local environmental factors. Multi-point temperature measurement wired temperature measuring devices need to be embedded in large-volume concrete before concrete pouring. They have poor flexibility, low measurement comprehensiveness, and a relatively complicated installation process. Utility Model Content
