結露が起ったりすることがあった。However, conventional adhesives for fixing gypsum boards 4, etc. as interior base materials harden slowly after being applied, as seen in blood-based adhesives 3, and the adhesive itself sag downwards or its moisture evaporates. Transferred to the interior base material side such as plasterboard 4,
This moisture causes mold to grow on the surface of the board 4, and furthermore, due to the poor insulation effect of the adhesive itself, synthetic resin foam is filled into the walls and interior base material for insulation. However, heat may be conducted through the adhesive portion, resulting in dew condensation on the surface of the interior base material.

As shown in the figure, the floating members 7 are bonded in appropriate numbers and at appropriate intervals using an appropriate adhesive, such as adhesive 6 made of rubber or vinyl acetate thread.
After applying an appropriate amount of adhesive on the right end surface of the floating member 7, the adhesive is applied to the upper surface of the raised adhesive 8, that is, in the case of FIGS. 2 and 3. An interior base material 4 such as gypsum board, plywood board, iron plate, etc. is attached to the right end of the adhesive 8, and the interior base material 4 is attached so as to form a certain space on the surface of the adherend.
The interior base material 4 is placed against the surface S of an adherend such as an inner wall via a floating member 7 pasted on the outer surface, and an adhesive 8 is applied so that the interior base material 4 is spaced a certain distance from the surface S of the adherend. Next, press the surface C of the interior base material 4 to bring it out vertically, or when the present invention is applied to a floor, level it out, and then open the space between the adherend such as an inner wall and the outer surface of the interior base material 4. In the case of a synthetic resin foam 5, for example, a urea resin, it is filled with a foamed material, and in the case of other resins, a circular portion is foamed after filling to form a heat insulating wall or floor. be.

のである。In short, the construction method according to the above description of the present invention involves attaching the floating member 7 to the surface of the adherend and attaching the interior base material 4 to the upper surface thereof via the adhesive 8, or After fixing the member 7 to the outer surface side of the interior base material 4, adhesive 8 is further applied on the upper surface of the floating member 7, and this adhesive 8 is applied upward along with the interior base material 4 from the surface C side of the interior base material 4. It aligns the body vertically and horizontally by pressing it toward the inner surface of the body.

ある。Here, since the wall and floor structures are a heat insulating structure, the floating member 7 is desired to have good heat insulating performance. For example, a small piece of synthetic resin foam, or a layer of plywood or synthetic ladle board 9 on a base plastic foam is considered, and if the insulation is not a big issue in this part, the insulation performance It is also possible to use a poor quality material as the floating member 7.

しかし、この時には断熱性能を考慮するならばその浮し
部材７の断面積は適宜小さくする等考慮されなければな

為の調整部材とするものである。Therefore, the adhesive 8 lifts the adherend and the interior base material 4 and lifts the member 7.
When fixing via the floating member 7, one side of the floating member 7 is fixed with a general adhesive 6, and the other side is simultaneously attached with this adhesive, thereby making it possible for the three parts to be fixed, This part serves as an adjustment member for vertically or horizontally positioning the interior base material 4.

ものである。Next, as mentioned above, the adhesive 8 used in the present invention, like the conventional gypsum adhesive B, does not sag by the time it hardens, or the moisture contained therein transfers to the interior base material 4 side such as gypsum board. An epoxy thread adhesive 8 is used in the present invention. This epoxy thread adhesive 8 is naturally formed from two components: a main agent made of epoxy resin and a hardening agent. In the present invention, the viscosity of the adhesive is adjusted by further mixing the hardening agent with an inorganic powder such as calcium carbonate. For example, the viscosity is increased to about 200 PS to prevent sag after being plated and until it hardens, and at the same time, the curing speed is accelerated and the overall capacity is adjusted to be large.

装下地材４に吸湿性の材料を使用しても、浮し部材７と
内装下地材４間の接着には何ら問題がないのである。By using an adhesive in which inorganic powder such as calcium carbonate is mixed into the epoxy adhesive 8, it naturally does not contain moisture, and unlike the conventional gypsum adhesive 3, the moisture in the adhesive is absorbed into the interior base material 4. It transfers to epoxy adhesives and does not cause problems such as mold growth, and since the viscosity is high and the curing time is short, which is unique to epoxy adhesive 8, there is no sagging during curing. Even if a hygroscopic material is used for the interior base material 4 because it does not occur and can be cured quickly, there is no problem in adhesion between the floating member 7 and the interior base material 4.

本発明における被心体と内装下地材４間の空間は、前記

略２５ｍｍ程度が被着体と内装下地材４間に必要とされ
る。In the present invention, the space between the cored body and the interior base material 4 is made of synthetic resin foam 5 such as urea resin or urethane resin as described above.
The space may be sufficient as long as it is a space for filling a heat insulating wall structure or a heat insulating floor structure, but in a wall structure, for example, about 25 mm is required between the adherend and the interior base material 4.

ができる。However, the width of this space is not limited to about 25 mm, and can be adjusted to be thicker or thinner, but in the relationship between the thickness of the floating member 7 and the thickness of the adhesive, the width of the floating member is larger than the adhesive thickness. The insulation effect can be enhanced by increasing the thickness.

ｍ〜１０ｍｍ程度が望まれるところである。Even when the above-mentioned epoxy adhesive 8 is used, the insulation properties are poorer than when polystyrene hemorrhoid synthetic resin foam is used for the floating member 7, so the thickness of the adhesive should be reduced as much as possible. The thinner the material, the better it is from the standpoint of insulation performance. However, if the interior base material 4 is too thin, it will interfere with adjusting the direct exposure of the stile or leveling the interior base material 4 using this adhesive, and there will be a limit to the adjustment.For example, when the interior base material 4 is carved into a wall, The thickness of adhesive 8 is at least 6 m in
It is desired that the thickness be about 10 mm to 10 mm.

適宜採用され得るのである。Since this adhesive 8 does not contain water, has a fast curing time, and has a high viscosity, for example, as shown in FIG. An appropriate number of floating members 7a such as pieces of foamed polystyrene laminated with plywood 9 or wood are attached to the floating members 7 at appropriate intervals.
After fixing cheesecloth 10 on the surface of a with a stitcher etc.
After filling synthetic resin foam, for example, urea resin foam 5 as a heat insulating material from the surface of the cheesecloth 10 using a hose 11 or the like and filling the cheesecloth 10 and the surface of the concrete wall, interior base material 4 is applied to the top surface of the cheesecloth 10. In addition to fixing the floating member 7 on the floating member 7 by leveling it using the adhesive 8, it can also be suitably employed in a heat insulating wall structure for fixing to a concrete surface.

作られるのである。Then, after fixing the interior base material 4 in parallel with the inner surface of the concrete at a certain distance using the floating member 7 and adhesive 8, the inner surface S of the adherend such as a concrete wall and the interior base material 4 are fixed. A synthetic resin foam 5 such as urea resin or urethane resin is externally inserted into the insulation material filling space formed between the outer surfaces C through a filling opening appropriately provided in the interior base material or from another suitable opening. By foaming or internal foaming,
The resulting filling creates an insulating wall or floor structure.

着できるのである。。As described above, the method of constructing a heat insulating wall or floor according to the present invention involves filling a synthetic resin foam for heat insulation between an adherend such as a wall or floor and an interior base material via a floating member and an adhesive. After forming the space, use the properties of the adhesive to apply the interior base material.
Since it is filled with a synthetic resin foam for heat insulation after vertical or water buffalo removal, the interior base material is made into feathers or horizontally between the surfaces of the adherends, which are the walls of concrete buildings, etc. In addition to being easy and reliable, it is possible to use an epoxy adhesive filled with inorganic powder, such as calcium carbonate powder, to adjust the viscosity of the adhesive to a high level. Even when used for structures or floor structures, it does not sag during the curing process, and since it does not contain moisture, it does not transfer moisture to the interior base material and cause mold, unlike conventional plaster adhesives. In addition, the insulation effect is also insulated by the floating member, and when the thickness of this adhesive is made thinner than the thickness of the insulation material, for example from about 6 mm to about 10 mm, the insulation effect is further improved and the interior of the wall is Even after attaching the base material, it can be fixed without the problems of the conventional method. .
