[0002] In the field of building construction, the application of concrete is extremely wide, especially concrete columns as the key support components of building structure, the construction quality is directly related to the overall stability and safety of building. However, low temperature can significantly affect the performance of concrete. On the one hand, the hydration reaction rate of concrete is greatly slowed down, which makes the setting time of concrete prolonged and the strength slowly increased. For example, under normal temperature, concrete may begin to set within a few hours, while in low temperature environment, the setting time may be extended several times, which seriously affects the construction progress. On the other hand, low temperature can also cause the internal water of concrete to freeze and expand, forming micro-cracks in the concrete, which reduces the strength and durability of concrete.

The commonly used method of manually wrapping thermal insulation materials not only has low efficiency and requires a large amount of manpower, but also cannot guarantee the close fit of the thermal insulation materials with the column, which is prone to gaps and leads to heat loss. Although some simple heat preservation sheds can provide a heat preservation environment to a certain extent, they have poor adaptability to concrete columns of different diameters and cannot meet the diversified construction needs.
