Description

  The present invention relates to a mounting structure for a floor heat insulating foundation panel disposed between a floor foundation and a finished floor material.

  As a conventional floor structure, there is known a structure in which a base panel including a heat insulating material (floor heat insulating base panel) is disposed between a floor base and a finished floor material (see, for example, Patent Document 1).

  In such a floor structure, the finished floor material is nail-fixed to the floor base via a floor heat insulating base panel, for example, at a site such as a male part.

  When vacuum insulation is included as an insulation material to be installed in the floor insulation base panel, if the vacuum insulation material is damaged, the heat insulation will be lost, so nailing is applied to the part where the vacuum insulation material is not arranged so as not to damage the vacuum insulation material There is a need. For this reason, it is customary to accommodate the vacuum heat insulating material in the center of the flat surface of the floor heat insulating base panel and nail it to the end of the floor heat insulating base panel.

  However, even if the floor insulation base panel with vacuum insulation material is viewed from the top, the exact location of the vacuum insulation material is not known, and the finished floor material is fixed by nailing to avoid the vacuum insulation material. It is difficult. It is possible to mark the upper surface of the floor insulation base panel so that the location of the vacuum insulation material can be identified, but in the manufacturing process, the displacement of the vacuum insulation material occurs due to the foaming pressure of the foamed resin. Therefore, it is not possible to reliably prevent damage using only the mark.

  The present invention has been proposed in view of such circumstances, and its purpose is to position the nailing of the finished floor material to the floor foundation so as not to damage the vacuum insulation material contained in the floor thermal insulation foundation panel. An object of the present invention is to provide a floor heat insulating base panel mounting structure capable of ensuring the above.

  In order to achieve the above object, the floor heat insulating base panel mounting structure according to the present invention includes a vacuum heat insulating material, a heat insulating panel having connecting portions at both ends, a non-vacuum heat insulating material, and the heat insulating properties at both ends. The floor thermal insulation base panel provided with the intermediate heat insulation panel with the connection part connected with the connection part of a panel was connected to the connection parts, and was installed in the floor base.

  Further, in the present invention, the connecting portion of the heat insulating panel and the connecting portion of the intermediate heat insulating panel are structured to be connected by fitting in the thickness direction, and the intermediate heat insulating panel is at least at one end and the heat insulating panel. It is good also as a structure connected with a loose fitting state.

  Moreover, in this invention, it is good also as a structure which fixes the bottom part of one connection part of an intermediate | middle heat insulation panel to a floor foundation with a fixing tool.

  According to the mounting structure of the floor heat insulation foundation panel of the present invention, since it has the above-described structure, when nailing the finished floor material to the floor foundation, the nail is provided so as not to damage the vacuum insulation material contained in the floor insulation foundation panel. You can hit.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  The floor heat insulating base panel 1 shown in FIG. 1 has a vacuum heat insulating material 14 provided therein, a heat insulating panel 10 having connecting portions 13 and 13 at both ends, and a non-vacuum heat insulating material 24, and the heat insulating panel 10 at both ends. The intermediate heat insulation panel 20 which has the connection parts 23 and 23 connected with the 10 connection parts 13 and 13 is comprised.

  These two types of heat insulation panels 10 and 20 are alternately disposed on the floor base 2 as shown in FIGS. 1 and 3A. That is, the intermediate heat insulation panel 20 is disposed between the two heat insulation panels 10 and 10.

  The heat insulating panel 10 is configured by housing a vacuum heat insulating material 14 and a foam heat insulating material 15 in a recess 12 of a base material 11 having a concave cross section. The vacuum heat insulating material 14 is installed at the approximate center in the width direction and the longitudinal direction of the heat insulating panel 10. Then, the foam heat insulating material 15 is filled around the vacuum heat insulating material 14.

  In the present embodiment, when the finished floor material 30 disposed on the floor heat insulating base panel 1 is nailed to the floor base 2, it is not necessary to penetrate the nail 5 through the heat insulating panel 10. Therefore, since there is no possibility that the nail 5 penetrates the vacuum heat insulating material 14, it is possible to use the one in which the vacuum heat insulating material 14 that is large in plan is equivalent to the flat surface of the heat insulating panel 10.

  The base material 11 of the heat insulation panel 10 includes a surface portion 11a (the bottom portion of the recess 12), both side portions 11b and 11b, and connecting portions 13 and 13 connected to the side portions 11b and 11b. The base material 11 is formed, for example, by bending a plate material in which a metal plate is covered with a resin layer.

  The connection parts 13 and 13 of the heat insulation panel 10 can be connected to the intermediate heat insulation panel 20 by fitting in the thickness direction. That is, one connection part 13 is comprised by the recessed part 13a which opened upwards, and the other connection part 13 is comprised by the convex part 13b which protruded below.

  The vacuum heat insulating material 14 may be formed by vacuum-sucking the core material with a gas barrier packaging material. As a core material, it is good also as what consists of foams, such as an open-cell urethane foam using a material with comparatively low heat conductivity, a styrene foam, a phenol foam. Alternatively, as the core material, it may be made by pulverizing various foam materials, or it may be made of powder particles such as silica, alumina, pearlite, etc., and it is made of fiber bodies such as glass fiber, glass wool, rock wool, cellulose fiber, etc. Also good. Furthermore, you may make it mix and use the above-mentioned various foams, a granular material, and a fiber body as a core material. The packaging material may be a metal film having gas barrier properties. Alternatively, a laminate having a protective layer such as a resin film on the outer layer side, a gas barrier layer such as a metal film or a metal vapor deposition layer in the middle, and a heat welding layer such as a resin film having heat weldability on the inner layer side (core material side) A film (sheet) may be used as a packaging material.

  Further, as the foam heat insulating material 15 disposed around the vacuum heat insulating material 14, a synthetic resin such as urethane resin, polystyrene resin, polyethylene resin, phenol resin, a foaming agent, and a curing agent or a flame retardant as necessary. Examples include foaming a foamed resin 31 containing the above. As the foamed resin, a foamed rubber-based material or an inorganic foamed material made of calcium carbonate or the like may be used.

  On the other hand, the intermediate heat insulating panel 20 is formed by filling a recess 22 of a base material 21 having a concave cross section with a non-vacuum heat insulating material 24 such as a foam heat insulating material. In addition, the base material 21 is provided with the surface part 21a (bottom part of the recessed part 22), both-sides part 21b, 21b, and the connection parts 23 and 23 connected to each side part 21b and 21b. Moreover, the base material 21 of the intermediate | middle heat insulation panel 20 may be manufactured with the same raw material as the base material 11 of the heat insulation panel 10, and may be manufactured with another various raw material. As a heat insulating material constituting the intermediate heat insulating panel 20, various heat insulating materials can be used as long as it does not include at least a vacuum heat insulating material.

  The connection parts 23 and 23 of the intermediate heat insulation panel 20 can be connected to the heat insulation panel 10 by fitting in the thickness direction. That is, one connection part 23 is comprised by the recessed part 23a opened upwards, and the other connection part 23 is comprised by the convex part 23b protruded below.

  In addition, the connection structure of the heat insulation panel 10 and the intermediate | middle heat insulation panel 20 is not restricted to said thing, A various connection structure is applicable.

  As shown in FIGS. 1 and 3A, the floor heat insulating base panel 1 has the heat insulating panels 10 and the intermediate heat insulating panels 20 arranged alternately in the width direction on the floor base 2.

  Further, two or more heat insulation panels 10 may be connected, and the intermediate heat insulation panel 20 may be connected to the end of the heat insulation panel connector. If it does in this way, since the heat insulation panel 10 containing the vacuum heat insulating material 30 will be continuously arranged, a high heat insulation effect will be acquired.

  The heat insulating panel 10 and the intermediate heat insulating panel 20 are connected by fitting the connecting portions 13 and 23 together. That is, the floor heat insulation base panel is formed by fitting the concave portion 13a of the heat insulation panel 10 and the convex portion 23b of the intermediate heat insulation panel 20 and fitting the convex portion 13b of the heat insulation panel 10 and the concave portion 23a of the intermediate heat insulation panel 20. 1 can be constructed.

  For example, as shown in FIG. 1, the intermediate heat insulation panel 20, the heat insulation panel 10, the intermediate heat insulation panel 20, the heat insulation panel 10,. These floor heat insulating base panels 1 may be fixed to the floor base 2 with an adhesive, and as shown in the figure, a fixing tool 25 such as a screw is attached to the bottom 23ab of the recess 23a of the connecting portion 23 of the intermediate heat insulating panel 20. It may be fixed.

  Thus, if one connection part 23 of the intermediate | middle heat insulation panel 20 is fixed to the floor foundation 2, when the finishing floor material 30 is installed on the floor insulation base panel 1, the movement movement of the floor insulation base panel 1 will be carried out. Can be prevented.

  Moreover, as shown in the figure, it is desirable that the convex portion 13b of the heat insulation panel 10 and the concave portion 23a of the intermediate heat insulation panel 20 can be coupled in a loosely fitted state. The convex portion 10b of the heat insulation panel 10 and the intermediate heat insulation panel It is desirable that the 20 recesses 23a can be coupled in a loosely fitted state.

  Since the connection structure can be coupled in a loosely fitted state as described above, the separation distance between the heat insulating panels 10 and 10 can be adjusted as shown in FIGS. The loose fitting structure may be formed on any one side of the panel.

  Next, an installation structure of the finished floor material 30 on the floor heat insulating base panel 1 will be described with reference to FIGS.

  For example, as shown in FIG. 3A, the finished floor material 30 is installed such that its longitudinal direction is orthogonal to the longitudinal direction of the heat insulating panel 10.

  The finished floor material 30 has a protruding male part 31 at one end in the width direction and a concave female part 32 at the other end. The finished floor material 30 is fixed by driving nails 5 against the floor base 2 on the upper surface of the base of the male part 31.

  The finished floor material 30 is nailed at a plurality of locations in the longitudinal direction of the male part 31, and any nailing is performed at a location above the intermediate heat insulation panel 20 (a location marked with x in FIG. 3A). The In this way, the finished floor material 30 is fixed to the floor base 2 by nailing at the upper part of the plurality of intermediate heat insulating panels 20, 20,.

  Thus, since the nail 5 for fixing the finishing floor material 30 penetrates the intermediate heat insulation panel 20, it is not necessary to penetrate the nail 5 through the heat insulation panel 10. Therefore, in the construction work of the finished floor material 30, there is no possibility that the vacuum heat insulation panel 14 built in the heat insulation panel 10 is damaged by the penetration of the nail 5.

  In other words, since the intermediate heat insulating panel 20 is arranged adjacent to the heat insulating panel 10 on the floor base 2, the floor floor of the finished floor material 30 is surely secured so as not to damage the vacuum heat insulating material 14 included in the heat insulating panel 10. The position of nailing to the ground 2 can be determined.

  Moreover, the finishing floor material 30 can also be constructed so as to be arranged in parallel to the intermediate heat insulation panel 20 without being arranged so as to be orthogonal to the longitudinal direction of the intermediate heat insulation panel 20 as described above. Even in such a case, the nail 5 penetrates the heat insulation panel 10 by arranging the finish floor material 30 so that the nail portion (male part 31) of the finish floor material 30 is located above the intermediate heat insulation panel 20. This can prevent the vacuum heat insulating material 14 from being damaged.
