The heat preservation template plays a key role in winter construction, and in the traditional heat preservation template and electric tracing maintenance method, all or part of an electric heating wire is embedded in concrete. After the concrete is poured, the electric heating wires are electrified to generate heat so as to provide the required heat for concrete curing. The electric heating wire buried in the concrete is a consumable material and cannot be recycled, and the electric heating wire may be damaged or broken in the pouring stage, so that the electric heating wire cannot be normally used. Great uncertainty is brought to the maintenance effect of the construction concrete in the winter period.
Some intelligent temperature control electric tracing heat preservation templates also gradually get into the engineering field in recent years, for this kind of template, solved the unable used repeatedly's of electrical heating wire problem, it adopts the mode of direct temperature measurement to guarantee the maintenance temperature of concrete mostly, and temperature measurement component buries underground inside the concrete. The method increases the construction process, prolongs the construction period, and simultaneously causes the consumption of labor hour and materials. The temperature control equipment mostly adopts fixed preheating time to preheat the cast-in-place concrete construction area, and when the environmental temperature changes differently, the intelligent control on the preheating time of the cast-in-place construction area can not be realized. When ambient temperature drops or the difference in temperature is great round clock, this type of heat preservation device probably can't guarantee the maintenance temperature of concrete, causes maintenance quality degradation scheduling problem.
For the two types of heat preservation measures, the steel bars are not preheated before concrete pouring, and under the condition of different temperatures in winter construction, the condition that the preheating temperature of the steel bars is insufficient or the steel bars are continuously heated after reaching the preheating temperature to cause energy waste can be caused.
In order to overcome the defects, the invention solves the problems that each heat preservation element cannot be recycled, and the maintenance temperature cannot be met when the environmental temperature changes greatly, and the like, and arranges a plurality of groups of electric tracing bands in a heat preservation template to intelligently control the power and the heating time of the heat preservation elements.
