  It is an object of the present invention to provide a method for efficiently transporting a heat insulating member in a narrow space under the floor when installing the heat insulating material under the floor of a building.

  This invention which achieved the said subject is a heat insulation member conveyance method in the underfloor space which arrange | positions the curing sheet made from a synthetic resin between underfloor soil, and slides and conveys a heat insulation member on this curing sheet.

  In the present invention, in the basic person entrance, the curing sheet having a width wider than the width of the person entrance is disposed along the inner wall of the person entrance, and a plurality of curing sheets are provided between the underfloor soils. It is preferable to arrange so that the curing sheet far from the underfloor inspection port is at the bottom and the curing sheet near the underfloor inspection port is at the top in the overlapping portion of the curing sheets.

  The curing sheet is obtained by laminating a film on the surface of a base made of a woven fabric or foamed resin, and it is preferable that the heat insulating member is slid on the film surface, and the film is a polyethylene film or a polypropylene film. preferable.

  Moreover, it is also preferable that at least one main surface of the heat insulating member is made of a nonwoven fabric, and the nonwoven fabric is slid on the curing sheet with the nonwoven fabric facing downward.

  According to the present invention, since the heat insulating member is slid and transported on the curing sheet made of synthetic resin, the heat insulating member can be efficiently transported even in a narrow space under the floor.

It is the schematic which showed an example of the preferable embodiment of this invention. It is the schematic which showed an example of the preferable embodiment of this invention. It is the schematic which showed an example of the preferable embodiment of this invention. It is the schematic which showed an example of the preferable embodiment of this invention.

  The heat insulating member is brought into the underfloor space from, for example, an underfloor inspection port, and is carried by a person to all places to be constructed. The underfloor space is only a space that allows one person to pass through alone, and it takes a lot of time to move through the underfloor space with a heat insulating member. Further, when the heat insulating member is transported by being pushed or pulled on the soil, a part of the heat insulating member may be damaged. Therefore, conventionally, it has been difficult to efficiently carry the heat insulating member to each place to be constructed without damaging it. Therefore, in the present invention, in the underfloor space, a curing sheet made of synthetic resin is arranged between the underfloor soils, and the heat insulating member is slid and transported on the curing sheet. By doing in this way, while being able to convey a heat insulation member efficiently, it can prevent that a heat insulation member is rubbed between soil at the time of conveyance, and is damaged.

  Especially in the underfloor space, the person entrance has an inner wall, and when the heat insulating member is transported through the person entrance, it may be damaged if it collides with the inner wall. Therefore, in the present invention, it is preferable that a curing sheet having a width wider than that of the person passage is disposed along the inner wall of the person passage. In this case, the end portion in the width direction of the curing sheet may be disposed along the inner wall of the person passage without being cut. FIG. 1 is a schematic view showing an example of a preferred embodiment of the present invention, and is a view showing a state in which a curing sheet 11 is arranged along an inner wall 13 of a person passage 12. As long as at least a part of the inner wall 13 of the person passage 12 is covered with the curing sheet 11, the arrangement mode is not limited. For example, as shown in FIG. Alternatively, the wide curing sheet may be arranged along the inner wall 13 as it is, or the curing sheet 11 is placed inside by making a cut 14 in the width direction of the curing sheet 11 as shown in FIG. It may be easy to follow the wall 13. In the configuration in which the curing sheet 11 wider than the person entrance 12 is disposed along the inner wall 13 of the person entrance 12, the height 1 / of the side wall (the rising portion of the foundation) from at least the lowermost part of the inner wall 13 is set. It is preferable that the region up to 3 positions (more preferably 1/2 position) is covered with the curing sheet 11, and it is also preferable that the entire area in the height direction of the side wall is covered with the curing sheet 11. Moreover, if the curing sheet 11 is along the inner wall 13 at least one of the inner walls 13 on the left and right sides of the person passage 12, the above-described effect is exhibited. Therefore, the center of the curing sheet 11 does not necessarily pass through the center of the person passage 12.

  The curing sheet may be used as it is without cutting the sheet on the roll, or a plurality of curing sheets may be used. FIG. 2 is a schematic view showing an example of a preferred embodiment of the present invention. When using a plurality of curing sheets in order to transport the heat insulating member to each place to be constructed, as shown in FIG. 2, in the overlapping portion between the curing sheets, the one farther from the floor inspection port 21 It is preferable to arrange the curing sheet 22 so that the curing sheet 23 located on the lower side and closer to the underfloor inspection port is on the upper side. In FIG. 2, the arrows indicate the conveyance direction of the heat insulating member. By doing in this way, at the time of conveyance of the heat insulation member 24, the curing sheet 22 is not turned up due to the passage of the heat insulation member 24 in the overlapping portion of the curing sheet, and the conveyance is not hindered. It becomes possible. In order to effectively prevent the curling sheet 22 from being turned up, the length of the overlapping portion between the curing sheets (transport direction of the heat insulating member 24) is preferably 3 cm or more, more preferably 5 cm or more, and even more preferably 8 cm. That's it. On the contrary, from the viewpoint that the heat insulating member 24 can be transported by a small number of curing sheets by reducing the overlapping portion, the overlapping portion is preferably 30 cm or less, more preferably 25 cm or less, and 20 cm or less. Further preferred.

  As described above, in the case where a plurality of sheets are partially overlapped with each other, the curing sheets may be arranged in order from a place far from the floor inspection port 21 toward a place close to the floor. In this way, the curing sheet 23 that is far from the underfloor inspection port 21 is placed below the underfloor inspection port 21 by overlapping the curing sheet 23 so as to partially overlap the curing sheet 22 that is laid first. It is possible to efficiently realize such an arrangement that the curing sheet 23 closer to the upper side is on top. Conversely, the sheets may be arranged in order from a location close to the underfloor inspection port 21. In this case, if the end of the curing sheet 23 closer to the underfloor inspection port 21 is turned over and the curing sheet 22 farther from the underfloor inspection port 21 is piled down and stacked, the underfloor inspection port 21 is The disposition where the farther curing sheet 22 is lower and the curing sheet 23 closer to the underfloor inspection port 21 is upper can be realized without the operator getting dirty between the soils.

  FIG. 3 is a schematic view showing an example of a preferred embodiment of the present invention. The plurality of curing sheets may be arranged such that the longitudinal directions are all the same direction, but among the plurality of curing sheets, the longitudinal direction of at least one curing sheet 32 is adjacent to the curing sheet 32. You may arrange | position so that the angle with the longitudinal direction of the curing sheet 31 may differ (for example, 45-90 degrees). In FIG. 3, the arrows indicate the conveyance direction of the heat insulating member. The shape of the heat insulating member varies depending on the place where the heat insulating member is installed, but the predetermined heat insulating member may not be transported in the construction order and the order may be changed. If the curing sheet 32 is arranged as shown in FIG. 3, materials such as a heat insulating member can be temporarily retracted at the end of the curing sheet 32.

  FIG. 4 is a schematic view showing an example of a preferred embodiment of the present invention. It is preferable that one curing sheet 40 is arranged directly below the underfloor inspection port, and when the shape of the underfloor inspection port is projected directly below the curing sheet, a projected image 41 (usually rectangular) of the underfloor inspection port. ) Is preferably within the curing sheet. Furthermore, it is preferable that at least one side of the projection image is substantially parallel to the short side of the curing sheet, and one side 42a (42b) of the projection image that is substantially parallel to the short side of the curing sheet, and closest to the side The distance 44a (44b) to the short side 43a (43b) of the curing sheet is preferably 30 cm or more, more preferably 40 cm or more, and further 50 cm or more. In many cases, the underfloor inspection port is usually provided in the vicinity of the peripheral portion rather than the central portion of the house, and it may be difficult to ensure both the distance 44a and the distance 44b long. Therefore, the distance 44a and the distance 44b may be, for example, 200 cm or less, 150 cm or less, or 100 cm or less.

  At least one of a region (a region between 42a and 43a, a region between 42b and 43b) between one side of the projection image substantially parallel to the short side of the curing sheet and the short side of the curing sheet closest to the side is It is preferable that the arrangement direction from the projected image is different from the conveyance direction 45 of the heat insulating member. As described above, the shape of the heat insulating member varies depending on the place where the heat insulating member is installed, but the predetermined heat insulating member may not be transported according to the construction order and the order may be changed. If the curing sheet 40 is arranged as shown in FIG. 4, a material such as a heat insulating member can be temporarily retracted at the end of the curing sheet 40.

  You may have an adhesive layer in the edge of at least 1 sheet | seat among several curing sheets. The curing sheet and the soil can be fixed by the pressure-sensitive adhesive layer, or the overlapping portion of the curing sheet can be fixed, and the shift of the curing sheet can be prevented. In addition, a snap button or a hook-and-loop fastener can be used instead of the adhesive layer.

  As the curing sheet made of synthetic resin, a sheet in which a film is laminated on the surface of a base made of a woven fabric or a foamed resin, or a film or sheet (such as a moisture-proof film or a moisture-proof sheet) can be used. In the curing sheet comprised from what laminated | stacked the film on the surface of the base which consists of a textile fabric or foamed resin, it is preferable to slide a heat insulation member on a film surface. By doing in this way, a heat insulation member can be conveyed efficiently. The film is laminated on the surface of at least one side of the base. Examples of the material for the woven fabric include polyethylene, and examples of the material for the foamed resin include polyethylene and polyurethane. Examples of the film include films of polyethylene, polypropylene, polyethylene terephthalate, vinyl chloride, etc. Among them, polyethylene and polypropylene (particularly polypropylene) are preferable.
