PROBLEM TO BE SOLVED: To dispense with large-scale curing equipment, to simplify handling and to enable easy diversion of equipment to other purposes and easy execution of initial curing. SOLUTION: Hot water subjected to temperature control by a hot water tank 16 which can regulate water temperature is made to circulate through a mat 10 fitted on the surface 11a of a heat insulating panel so disposed as to surround a form, from a water supply pipe 14 to a draining pipe 13 through a water supply hose 17 and a draining hose 18, and thereby concrete placed inside the form is heat-insulated and cured by using the hot water flowing through the inside of the mat 10. The heat insulation and curing are effected efficiently by insulating the form thermally from the surroundings by the heat insulating panel 11 on which the mat 10 is fitted. Since the mat 10 can expand and contract freely, it can be stored compactly by removing the hot water and also is convenient for diversion. |
