Due to the particularity of concrete materials, a template is inevitably used in the concrete structure pouring and curing process to achieve the purpose of shaping concrete, however, if effective measures cannot be taken to reasonably control the heat generated by the concrete materials in the process, temperature cracks are easily formed on the surface or in the structure. These temperature cracks reduce various properties of the structure itself due to the external environment and its properties during the use of the structure, affect the durability of the structure, and seriously cause the structural damage.

At present, in order to control the adverse effect caused by the heat release of concrete materials, an insulating layer is usually covered on the outer side of a concrete template so as to slow down the heat exchange between the surface of a structure and air, and further reduce the temperature difference on the inner surface of the structure so as to reduce the temperature cracks generated by the structure. However, in practical application engineering, due to the influence of field environment, equipment and actual construction of personnel, the heat insulation layer is covered on the surface of the structure to isolate heat exchange, and the temperature control effect is not ideal. The main performance is that the local area is inevitably communicated with air, and the local area cannot be covered with the heat-insulating layer.
