Since only a weak adhesive or adhesive is interposed between the surface material and the heating panel, it is easy to separate the interface between the two, and the heating panel and the high specific gravity sheet below it are: It is easy to separate the heating panel from the high-density sheet because the nonwoven fabric is only adhered by the nonwoven fabric and the adhesive tape, and only breaks the nonwoven fabric when these interfaces are peeled off.
- the high specific gravity sheet is placed on the heating panel in the floor structure of the first invention.
- a heating panel is placed on the existing floor, and a high specific gravity sheet is placed on it.
- a load weight
- Friction between the heating panel and the existing floor can be prevented from slipping (moving). In other words, it is possible to prevent the heating panel from being displaced or floating with respect to the existing floor surface.
- reference numeral 4 denotes a heating panel
- reference numeral 2 denotes a high specific gravity sheet
- reference numeral 11 denotes a partition member described later
- reference numeral 8 denotes a surface material. ing.
- an adhesive may be interposed at the interface between the heating panel and the existing floor.
- an adhesive it is preferable that the adhesive force is weak and a coating mark hardly remains after the adhesive is removed.
- the heating panel, high specific gravity sheet, and surface material used in the second embodiment of the first invention are the same as those in the first embodiment of the first invention.
- a partition member on the high specific gravity sheet that is, between the high specific gravity sheet and the surface material.
- the material of the partition material include resin, paper, wood, and inorganic materials having high heat resistance. Specific examples include various types of flexible or rigid thin plates, powders, non-woven fabrics, and woven fabrics. Most commonly, non-woven fabrics or woven fabrics are used.
- the thermal resistance is as low as possible. Specifically, the thermal resistance may be 0.01 m 2 KZW or less, preferably 0.001 m 2 KZW or less.
- the thickness of the nonwoven cloth as the partitioning material is preferably in the range of 0.01 to 1 mm, more preferably in the range of 0.05 to 0.5 mm.
- the construction method according to the third invention is a construction method of the floor structure according to the second embodiment of the first invention, and in laying the heating panel on the existing floor surface, disposing the heating panel on the existing floor surface.
- reference numeral 11 denotes a partition member.
- a heating panel is arranged on the existing floor surface. Considering the restoration work at the end of the rental period, it is preferable not to interpose an adhesive between the existing floor and the heating panel. In the case where an adhesive is interposed exceptionally, as described above, the adhesive force is weak, and after removing the adhesive, it is difficult to leave a trace of the coating.
- the location where the heating panel is arranged can be limited to the portion of the existing floor surface to be heated, and the area of the heating panel can be smaller than the area of the high specific gravity sheet placed thereon. In the area where the existing floor is exposed without heating panels
- a dummy plate (one in which the fluid tube is not embedded in the same plate-like body that forms the heating panel) is placed.
- a high specific gravity sheet is placed on the heating panel and the dummy plate.
- a second partition member may be further sandwiched on the heating panel. By interposing the second partition member between the heating panel and the high specific gravity sheet, it is possible to prevent the heating panel and the high specific gravity sheet from sticking.
- the high specific gravity sheet applies a load (weight) to the heating panel and the dummy board to prevent the heating panel and the dummy board from floating from the existing floor, and to prevent friction between the existing floor and the heating panel and the dummy board. Increase the power and fix the heating panel and dummy plate to the existing floor.
- the high specific gravity sheet is desirably disposed so as to cover 60% or more, preferably 80% or more of the surfaces of the heating panel and the dummy plate in order to sufficiently exert the frictional force described above.
- the most effective way to fix the heating panel and dummy plate is to lay high specific gravity sheets without gaps.
- a partition member (a partition member indicated by reference numeral 11 in FIG. 6) is arranged on the high specific gravity sheet.
- the partitioning material By arranging the partitioning material and cutting the high-specific-gravity sheet and the surface material, the sticking of the high-specific-gravity sheet to the surface material can be prevented. It can be prevented from being transmitted. Therefore, it is desirable to lay the partition material over 80%, preferably 90% or more of the surface of the high specific gravity sheet. Most preferably, a plurality of nonwoven fabrics are laid without gaps while being overlapped to a thickness of about 1 cm so that the high-specific-gravity sheet and the surface material do not come into contact with each other. It is preferable that the nonwoven fabric is temporarily fixed on a high specific gravity sheet with a double-sided tape. However, the purpose of temporary fixing is to prevent misalignment during construction that is not fixed.Temporary fixing is usually performed at intervals of about 1 every 2 m. What,
- the material when arranging the facing material on the partition material, it is preferable that the material is not fixed in order to facilitate the on-site recovery.
- the heat medium flowing through the heat medium tubes of the installed heating panel is adjusted in temperature and pressure by a heat medium circulating device, and is dispersed and circulated (circulated) through the heat medium tubes through the header.
- the heat medium circulation device is installed at an appropriate place outdoors or indoors.
- the surface covering material is peeled off, and then the high specific gravity sheet is peeled off. Since the partitioning material is interposed between the facing material and the high specific gravity sheet, it is easy to separate the interface between the two, and the interface between the high specific gravity sheet and the lower heating panel is low. The high specific gravity sheet on the heating panel can be easily peeled off, because it is only adhered by the load.
- the heating panel After removing the high specific gravity sheet, finally, the heating panel is peeled off from the existing floor surface. In most cases, no adhesive is interposed between the existing floor surface and the heating panel, and even if it is used, a weak adhesive is used that does not easily leave traces of adhesion. Even if the part remains on the existing floor, it is easy to remove and does not remain as an adhesive trace. Also, since none of the exterior materials, heating panels and high specific gravity sheets are screwed or nailed, these fixing holes do not remain on the floor. Therefore, the appearance of the existing floor is not slightly damaged, and the appearance can be maintained. Exfoliated coverings, heating panels and high specific gravity sheets can also be reused, as they are not damaged. Example
