Description of the Related Art Heat insulation devices such as pipes and tanks are periodically inspected for heat insulation performance, and if the heat insulation performance deteriorates, repairs are made. When a decrease in the heat insulation performance is recognized, the heat insulation material itself may be deteriorated, but a gap is often formed between the heat insulation materials and the heat insulation is often defective.

なるためその処理、処分方法なども問題となる。However, in the above-described method of installing the heat insulating device, it takes time to attach the outer material again and replace the heat insulating material after the outer material is removed or repaired. In addition, a large-scale work scaffold may be required, which requires more than twice as much labor as when a new heat insulating device is installed. Further, there is a problem in the working environment that dust harmful to the human body is easily generated during these works. In addition, since the used heat insulating material that has been replaced becomes industrial waste, there is a problem in its treatment and disposal method.

が得られる。In the method of installing a heat insulating device of the present invention, partial installation is performed by piercing the surface of the exterior material at a defective portion with a drill or the like, providing an injection hole for the heat insulating filler, and injecting the heat insulating filler. Thereby, the same heat insulating effect as in the case where the exterior material is removed, the gap between the heat insulating materials is filled with rock wool or a compound heat insulating material, or the heat insulating material is replaced can be obtained.

The injection of the heat-retaining filler is performed using an injection machine such as a hand gun. After injecting the thermal filler, the injection hole is mastic tape, caulking material,
It is closed by covering with a metal plate or the like.

As shown in FIG. 2, an injection hole 5 for injecting the heat-retaining filler material is provided by drilling a hole in the exterior material 3 corresponding to the position of the gap 4 with a drill or the like. Material 6 is injected. The heat retaining filler 6 is accommodated in an injection cartridge 7 and injected by a hand gun. A dedicated nozzle 8 is attached to the tip of the cartridge 7. Thereby, the heat retaining filler 6 can sufficiently spread to the deep part. After the injection of the heat retaining filler 6 is completed, the work is completed by closing the injection hole 5 with a mastic tape 9 as shown in FIG.

省エネルギーの効果をあげることができる。As described above, according to the method for repairing a heat insulating device of the present invention, repair work can be performed without performing dismantling work such as removal of an exterior material or replacement work of the heat insulating material. Since a large-scale work scaffold is not required, labor required for repair work is greatly reduced, and work time is also reduced. Further, generation of dust harmful to the human body during work can be suppressed. In addition, it does not replace insulation materials, greatly reducing industrial waste, preserving the environment,
Energy saving effect can be obtained.
