Description

Technical Field

[0001] This utility model relates to the field of construction technology for large-volume concrete in building engineering, and in particular to a temperature measuring device for large-volume concrete. Background Technology

[0002] In recent years, large-volume concrete structures have become increasingly common. Due to their thickness, these types of concrete often generate a large amount of hydration heat during construction. Temperature changes between the inside and outside of the concrete cause cracks and affect the quality of the concrete molding.

[0003] Currently, temperature measurement in large-volume concrete mainly employs two methods: pre-embedded temperature sensing wires and pre-embedded temperature sensing tubes. The traditional pre-embedded temperature sensing tube method typically uses PVC pipes through which the sensing wires are pre-embedded. However, because the PVC pipe creates a continuous airflow space, the temperature sensing point at the bottom of the pipe is easily affected by airflow, leading to inaccurate temperature readings. Furthermore, the temperature sensing tube lacks a support structure, making it difficult to secure. The pre-embedded temperature sensing wire method generally involves directly binding the sensing wire to the vertical reinforcing steel before concrete construction. The disadvantage of this method is that the sensing wire is directly exposed in the concrete. During concrete construction, the impact of pouring and vibration can easily damage the sensing wire and temperature sensing element, affecting temperature measurement. Utility Model Content
