ようとしている。[Detailed Description of the Invention] The present invention relates to a method for insulating concrete buildings, which is easy to perform, does not create gaps in the joints of the insulating material, and does not cause slag seepage during concrete pouring or condensation after construction. I'm trying to provide a method that doesn't exist.
従来より、パネル状の断熱材Ｐをコンクリート

性にも優れたものとされている（第１図）。 Conventionally, a panel-shaped heat insulating material P is used as a formwork for concrete pouring, concrete is poured directly on the back side of this heat insulating panel P, and a concrete frame C is formed.
An insulation construction method is adopted in which the concrete frame C and the insulation panel P are joined at the same time as the formation of Figure 1).

は外観上も好ましく改善が要望されていた。 However, in the above construction method, gaps tend to form at the seams A between the insulation panels P during concrete pouring, and concrete slag seeps through these gaps, staining the surface of the insulation panels. When using P' with interior material P'' attached in advance, the above-mentioned slag leaching is favorable in terms of appearance, and improvement has been desired.

ずる欠点があつた。 In addition, with conventional construction methods, even after construction, over time, as the concrete wall C expands and contracts due to fluctuations in outside temperature, gaps may occur between the insulation panels P, and the gaps may become wider in areas with higher temperatures. At the same time, the concrete frame C facing the cold outdoor side is directly exposed to the high temperature indoor side with a large temperature difference due to the generation of gaps, so the indoor space inside the gaps is exposed during the winter. There was a problem with dew condensation on walls, etc.

に接合してなることを特徴とするものである。 Therefore, in the method of the present invention, the above-mentioned conventional drawbacks are solved, and no gaps are created between the insulation panels during concrete pouring or after construction, and a good appearance and insulation effect can be maintained.
The method is to attach an insulating material that is smaller than the interior material and has a stepped or tapered part that is smaller on the opposite side than the side to which it is attached to the interior material, inward from the side edge of the interior material. The insulation panel is temporarily installed as an inner frame for pouring concrete, and at this time, the space between the side edges of the insulation material that occurs on the back side of the interior material at the joint between adjacent insulation panels is At the same time as forming the concrete frame, by inserting an elastic body that closely matches the above-mentioned inner frame and placing concrete in the gap between the insulation panel and the outer frame that was temporarily constructed opposite to the above-mentioned inner frame. It is characterized by being formed by integrally joining a heat insulating panel and an elastic body.

る。 According to the method of the present invention configured as described above, slag leaching from the panel joints, which was a drawback when the insulation panels are used as formwork for concrete pouring, can be avoided at the sides of the insulation materials that form the panel joints. It can be completely blocked by installing an elastic body that fits into the space formed between the ends. In addition, even if there is a manufacturing error on the insulation material side or an assembly error occurs during temporary panel installation, the elastic material has elasticity or deformability, so the elastic material can be tightly fitted into the space shape and the insulation material on both sides can be closed. Because it is possible to join
Compared to simply butting insulation materials together,
The adhesion is much better and there are no gaps between the insulation panels. Moreover, the elastic body is pressed from behind against the side edges of the insulation material or the back surface of the interior material on both sides by the pouring pressure during concrete pouring, which further improves adhesion and completely blocks out slag seepage. Put it away. Regarding the improvement of the adhesion force due to the above-mentioned pouring pressure, the cross-sectional shape of the elastic body makes the contact surface with the interior material smaller than the contact surface with the concrete. Since a step or taper is formed on the side edge so that the concrete side on the back side is smaller than the adhesive side, it is possible to effectively convert the driving pressure from the back side of the elastic body into adhesion force with the side edge of the insulation material. . Furthermore, after insulation construction, the difference in the amount of expansion and contraction between the concrete frame on the outdoor side and the insulation panel on the indoor side due to the temperature difference between indoors and outdoors can be absorbed by the expansion and contraction deformation of the elastic body. That is, at night or in the winter, the temperature on the indoor side is higher than on the outdoor side, and during the day or in the summer, the temperature on the indoor side is lower than the outdoor side. In this way, due to daily or seasonal changes in the temperature difference between indoors and outdoors, there is a difference in the amount of expansion and contraction between the concrete wall and the insulation panel, and due to this, gaps are created at the joints of the insulation panel. Therefore, it is possible to prevent dew condensation inside the gap due to the generation of the gap, and also to prevent deterioration of the heat insulation properties.
