Description

Technical Field

[0001] The utility model relates to the field of concrete construction, and particularly relates to a concrete temperature acquisition device. Background Technique

[0002] Concrete is the most common material in modern engineering structures and is widely used in the fields of water conservancy, civil engineering, architecture, transportation, bridges, etc. Concrete has good mechanical properties, high economy, and is easy to construct mechanically. However, during the pouring process of concrete, due to the hydration reaction of cement, heat will be generated inside. As a poor conductor, concrete has poor heat conduction and heat dissipation performance, resulting in temperature stress being easily generated during the pouring process of concrete. Especially on the surface of concrete, once the temperature tensile stress exceeds the tensile strength of concrete, cracks will appear on the surface of the concrete structure, affecting the overall structural performance of concrete.

[0003] For concrete construction, especially the construction of mass concrete, it is of great significance for temperature control and crack prevention to monitor the internal temperature change of concrete in real time through temperature sensors. The existing temperature control monitoring mostly uses handheld monitoring devices, and the monitoring efficiency is relatively low. Some automatic acquisition devices are unreasonably arranged, resulting in poor monitoring stability. Especially for large-scale temperature monitoring, it cannot meet the engineering requirements.
