However, with this construction method, it is difficult to provide heat insulating material around window frames or door frames, for example, due to the construction process. This is because window frames and other items are installed after concrete frame work, and a space (gap) is required between the frame and the frame for installation, and the area around the window frame or door is This is because the structure is complicated and it was difficult to fill this part with plate-shaped heat insulating material, and this part was often left unfilled.

For this reason, attempts have been made to provide some kind of heat insulating material to the above-mentioned heat insulating defective portion. For example, one such attempt is to fill the insulation defect with mortar, but since mortar itself has a high thermal conductivity, it is difficult to provide good insulation performance. In addition, a method of filling insulation defects by mixing bead-shaped foamed plastics such as expanded polystyrene with mortar is being considered, but since mortar is often used, the problem is that the insulation performance is poor. there were.

For this reason, foamable urethane is poured into the insulation defects.
A method has been proposed in which foaming occurs in this defective part. However, with this method, it is not easy to control the foaming of urethane, and it inevitably flows out of the insulation defect and adheres to the surrounding area, and it takes time and effort to remove this deposit, and it also causes the insulation defect to flow out and adhere to the surrounding area. There was a major problem in that it took time and effort to scrape off the foamed parts that protruded from the 10th part.
