Concrete sample curing room and temperature adjusting method thereof

Abstract

The invention discloses a concrete sample curing room and a temperature adjusting method thereof, and solves the problem that the temperature in the curing room is non-uniform. The key points of the technical scheme lie in that temperature detection elements output temperature detection signals to a control terminal according to the indoor temperature of the curing room; the control terminal has a preset temperature reference value signal and can compare temperature detection signals with the temperature reference value signal; if the values of one or more temperature detection signals are lower than that of the temperature reference value signal, the control terminal controls a heating device and a heat dissipation device at the corresponding position to be started and shut down respectively; if the values of one or more temperature detection signals are higher than that of the temperature reference value signal, the control terminal controls the heat dissipation device and the heating device at the corresponding position to be started and shut down respectively. According to the concrete sample curing room and the temperature adjusting method thereof, the temperature at multiple positions can be monitored and adjusted simultaneously, so that the indoor temperature can be adjusted more conveniently to be more uniform, and the temperature adjusting efficiency can be improved.

Description

technical field [0001] The invention relates to the control of the test environment of concrete test pieces, in particular to a concrete test piece curing room and a temperature adjustment method thereof. Background technique [0002] With the continuous development of concrete technology and the use of high-performance concrete and admixtures, people's attention to the long-term deformation performance of concrete materials has gradually increased, and many test indicators for the long-term performance of concrete have gradually become familiar to people, such as: concrete shrinkage performance , Concrete plastic shrinkage performance, concrete dry shrinkage performance, concrete creep performance and so on. [0003] The effective testing of these indicators plays a decisive role in the accurate judgment of concrete performance. In the process of testing concrete deformation performance indicators, the problem of the test environment should be solved first. Whether the rel...

Problems solved by technology

[0005] In order to improve the efficiency of the test, the curing room will be set larger to facilitate the placement of more concrete specimens. At the same time, concrete specimens are placed in the entire curing room, and the above-mentioned scheme can be used in a large curing room. The temperature can be controlled, but it can only be controlled roughly. The overall control accuracy is low, and it is easy to have temperature differences in different areas of the room. In addition, the environment of concrete specimens in the same curing room still has certain deviations, resulting in inaccurate detection of various performance indicators, so there is a certain room for improvement
