Received from the controller 10 is configured as a printer 130 for printing the curing temperature over time graph.

The controller 10 preferably uses a microprocessor, and the thermal insulation film 60 preferably uses any one selected from vinyl, synthetic fiber, nonwoven fabric, and the like.

The steam integrator 110 has a steam temperature sensor 110a installed therein to detect a temperature therein.

Next, the operation and effects of the curing system of the concrete building structure using the steam boiler according to the embodiment of the present invention configured as described above will be described.

First, the outer surface of the concrete building structure 180 is surrounded by a heat insulating film 61 and sealed, and then the boiler 100 is installed in the heat insulating film 61.

The concrete building structure 180 is appropriate to install one boiler 100 for the concrete building structure 180 of about three floors to be cured by construction, the boiler 100 is the elevator core 150 of the lower floor It is preferable to install in).

The first to n-th concrete building partitions each room (room) as a partition, and between the thermal insulation film 61 and the concrete building structure 180 will be referred to as a concrete building partition for convenience.

Next, after water is stored in the water storage tank of the boiler 100, the pipe 140 for steam supply from the boiler 100 into the first to nth concrete building partitions 181, 182, 18n. The steam integrator 110 with the steam temperature detecting sensor 110a installed therein, and at the same time the first to nth concrete building partitions 181, 182, 18n. n Provide temperature detecting sensors 51, 52, 5n.

After installation as described above, input the temperature to be cured using the input means 70 is received by the controller 10 and stored in the ROM 30, using the input means 70 of the boiler 100 When the operation signal is input, the control signal is output from the controller 10 to the relay RY1. Thus, the relay RY1 is excited, and the movable contacts a and c of the relay RY1 are connected to the relay RY1. As the AC power is applied to the fuel ejection pump 80 from the AC power supply unit 18 by contacting the fixed contacts b and d, the fuel ejection pump 80 is switched on and stored in the fuel tank 82. Present fuel is blown into the burner (90).

At this time, as the combustion air is supplied to the burner 90 together with the combustion fuel, sparks are generated in the burner 90 to burn the combustion fuel, thereby generating thermal power, and the thermal power generated by the burner 90.

When the temperature is higher than the preset temperature in the RAM 30, the control signal is not output to the relay RY1 by blocking (off) the control signal output to the controller 10, so that the relay RY1 As the movable contact a, c is separated from the fixed contact b, d of the relay RY1, respectively, AC power is not applied to the fuel injection pump 80 from the AC power supply unit 18, so that the fuel injection pump 80 is switched off and stored in fuel tank 82 At the same time, the fuel is not ejected to the burner 90, and the burner 90 is also turned off so that the boiler 100 does not heat the water stored in the water tank.

In addition, a steam temperature sensor 110a is built in the steam integrator 110 so that the temperature in the steam integrator 110 can be detected by the steam temperature sensor 110a to provide the controller 10 to the controller 10. As output, the temperature in the steam integrator 110 may be prevented from being excessively raised, thereby preventing the occurrence of a safety accident.

Then, the temperatures of the first to nth concrete building partitions 181, 182, 18n are respectively detected by the first to nth temperature detection sensors 51, 52, 5n.
