<Embodiment 1>
The heat insulating material fitting 1 of the present embodiment is substantially the same as a conventional heat insulating material fitting, and is a locking piece that is hooked on a joist 4 (however, it is possible to use a large scale) that is a structural member of the foundation 3 of the building 2. 5, a hanging piece 6 bent downward from the end of the locking piece 5, and a pedestal 8 that is bent substantially horizontally from the lower end of the hanging piece 6 and supports the placed heat insulating material 7. Have. In particular, the support piece 9 is bent from the end of the pedestal 8, and the inner end edge 9a of the support piece 9 is substantially disposed on the extension line L of the drooping piece 6 (FIG. 1). See). When the heat insulating material 7 is placed and supported on the base 8 of the heat insulating material mounting tool 1, the inner end edge 9 a of the support piece 9 contacts the side surface of the joist 4, so that the load of the heat insulating material 7 is transmitted to the joist 4. It is possible to support the heavy heat insulating material 7 by applying a reaction force to the joists 4 (see FIG. 2). In particular, even if the heat insulating material is disposed between the large pulls having a large span, the heat insulating material can be favorably supported. Incidentally, the inner end edge 9a of the support piece 9 may be displaced from the extension line L of the drooping piece 6 within the range in which the inner end edge 9a of the support piece 9 can be in contact with the joist 4 when the heat insulating material 7 is supported by the pedestal 8. The same applies to the embodiment).

  The structure of the heat insulating material fixture 1 is demonstrated concretely.

  The material of the heat insulating material fitting 1 is preferably a metal having corrosion resistance such as iron or stainless steel subjected to surface treatment such as galvalume steel plate or galvanized steel plate, and the thickness thereof can be bent by a person, and the heat insulating material. It has the strength to support 7 and is preferably about 0.3 mm to 0.5 mm in consideration of cost. The width dimension is determined in consideration of the number attached to the joists 4 to support the heat insulating material 7, the weight of the heat insulating material 7, and the like, and is about 15 mm, for example.

  The locking piece 5 has a length substantially equal to the width dimension of the joist 4 and is, for example, about 45 mm, and is continuous with a hanging piece 6 formed by being bent substantially vertically downward from both left and right ends thereof. . The predetermined position of the locking piece 5 is punched leaving a triangular base, and the piercing piece 10 is formed by bending the punched portion substantially vertically downward (the invention according to claim 2). When the piercing piece 10 of the locking piece 5 is driven into the joist 4, the heat insulating material fitting 1 can be attached to the joist 4.

  The hanging piece 6 has a height H that is substantially equal to the thickness h of the heat insulating material 7 and is, for example, about 30 mm, and a base 8 that is formed by being bent substantially horizontally from the lower end thereof outward. It is continuous. A predetermined position of the hanging piece 6 is punched out leaving a bottom of a long and thin pentagonal shape, and the leaf spring 11 is formed by bending the punched portion outward into a square shape. When the heat insulating material 7 is disposed between the joists 4 and 4 and the heat insulating material 7 is supported by the heat insulating material mounting tool 1, the side surface of the heat insulating material 7 can be firmly restrained by the leaf spring 11.

  The overhang length of the pedestal 8 is determined in consideration of the weight of the heat insulating material 7 and the like, and is, for example, about 20 mm, and is bent downward from both ends of the pedestal 8 across the hanging piece 6. It is continuous with the formed support piece 9. Incidentally, if a piercing piece is also formed upward at a predetermined position of the pedestal 8, the piercing piece can be inserted into the bottom surface of the heat insulating material 7 and fixed (not shown).

  The support piece 9 is formed in a right triangle, and is arranged so that one side sandwiching the right angle is continuous with the base 8 and the other side is the inner end edge 9a. The height of the inner end edge 9a is determined by the weight of the heat insulating material 7 to be supported, and is about 20 mm, for example.

Insulation material fitting 1 having the above structure, can be created by pressing, to create by bending a plate member in the field site. At this time, the notch 12 is formed in the flat plate member at a plurality of pitches in advance, and the notch 12 is bent and formed so that the height H of the hanging piece 6 and the thickness h of the heat insulating material 7 are substantially equal. (Inventions according to claims 4 and 5 ). When the heat insulating material 7 is disposed between the joists 4 and 4, the upper surface of the heat insulating material 7 and the upper surface of the joists 4 can be substantially flush with each other, and the upper surface of the heat insulating material 7 and the floor base material 13 (FIG. 4). ) Can be brought into close contact with each other. Therefore, heat insulation is high.

  The floor heat insulating structure of a building is constructed as follows using the heat insulating material mounting tool 1 having the above configuration, for example.

  First, the locking piece 5 of the heat insulating material fitting 1 is hooked and attached at a predetermined interval to a plurality of joists 4 spanned between the large pulls 14 and 14 in the foundation 3 of the building 2 (see FIG. 3). ). At this time, the joist 4 arranged at the inner position of the base portion 3 uses the heat insulating material mounting tool 1 having the above-described configuration, A heat insulating material fitting 1 ′ cut at an appropriate position of the locking piece 5 is used.

  Next, between the joists 4 and 4 (4 ′), the heat insulating material 7 is fitted from above between the heat insulating material fittings 1 and 1 (1 ′) facing each other to support the heat insulating material fitting 1 (1 ′). It pushes in until the inner edge 9a of the piece 9 contacts the side surface of the joist 4 (4 ′), and the heat insulating material 7 is placed on the base 8 and supported.

Finally, the floor base material 13 is laid on the upper surface of the heat insulating material 7 (see FIG. 4, the invention according to claim 6 ).

  As described above, since the inner end edge 9a of the support piece 9 of the heat insulating material fitting 1 (1 ′) is in contact with the side surface of the joist 4 (4 ′), the load of the heat insulating material 7 is changed to the joist 4 (4 ′). ), And the heavy insulating material 7 can be supported by applying a reaction force to the joists 4 (4 ′). In particular, even if the heat insulating material is disposed between the large pulls having a large span, the heat insulating material can be favorably supported.

  Incidentally, the heat insulating material 7 is preferably lightweight and excellent in water resistance, heat insulating property, and pressure resistance, and a synthetic resin foam having closed cells is preferable. Specifically, for example, a synthetic resin foam having closed cells such as a polystyrene foam, a polyethylene foam, a polypropylene foam, a polyurethane foam, and a phenol foam is preferable. In particular, extruded polystyrene (trade name “Styrofoam” manufactured by Dow Chemical Co., Ltd.) is most preferred because of its high heat insulation and low water absorption.

<Embodiment 2>
Although the heat insulating material fixture 1 of the said Embodiment 1 is set as the structure which mounts and supports the heat insulating material 7 in the base 8, it is not this limitation.

That is, the heat insulating material mounting tool 101 of the present embodiment is configured substantially the same as the heat insulating material mounting tool 1 of the first embodiment, but the outer end (tip) of the base 8 is used as the heat insulating material 7. It is set as the structure inserted and supported to a side part (refer FIG. 5). When constructing a floor heat insulating structure using this heat insulating material attachment 101, first, the heat insulating material attachment 101 is arranged so that the upper surface of the heat insulating material attachment 101 and the upper surface of the heat insulating material 7 are substantially flush with each other. The outer end of the pedestal 8 is inserted into the side of the heat insulating material 7, and each heat insulating material fitting 101 inserted into the heat insulating material 7 is attached to the joist 4, and the heat insulating material 7 is placed between the joists 4 and 4 facing each other. The heat insulating material 7 is supported on the base 8 of the heat insulating material mounting tool 101. Finally, a floor base material is laid on the upper surface of the heat insulating material 7 (the invention according to claim 7 ). Therefore, the heat insulating material fixture 101 can be used regardless of the thickness of the heat insulating material 7, and is highly versatile.

  In addition, if the base 8 is made into the shape where the front-end | tip part was pointed, it will be easy to insert in the heat insulating material 7, for example, is formed in planar pentagon shape. Further, if a piercing piece 15 bent inward is formed at a predetermined position of the base 8, it can be pierced without resistance when the heat insulating material 7 is pierced. (Invention of claim 3)

  And since the base 8 etc. of the heat insulating material attachment tool 101 are inserted into the heat insulating material 7 and are not exposed, it does not become a thermal bridge but is excellent in terms of heat insulating properties.

<Embodiment 3>
In the heat insulating material mounting tool 1 of the first embodiment, the support piece 9 is formed by bending downward from the end portions on both sides sandwiching the hanging piece 6 of the base 8, but this is not restrictive.

  That is, the heat insulating material mounting tool 201 of the present embodiment is configured substantially the same as the heat insulating material mounting devices 1 and 101 of the first and second embodiments, but is bent inward from the outer end of the base 8. (See FIG. 6).

<Embodiment 4>
Although the support piece 9 is formed in the right triangle in the heat insulating material fixture 1 of the said Embodiment 1, the shape is not specifically limited, In short, the inner end edge 9a of the support piece 9 is the extension line L of the drooping piece 6. It suffices if it is almost arranged above.

<Embodiment 5>
Although the folding angle of the locking piece 5 and the hanging piece 6 is approximately 90 degrees in the heat insulating material mounting tool 1 or the like of the first embodiment, the bending angle may be 90 degrees or more. For example, when the heat insulating material mounting tool 301 having substantially the same configuration as that of the heat insulating material mounting tool 1 according to the first embodiment and only the bending angle is set to about 100 degrees will be described, the heat insulating material mounting is performed similarly to the first embodiment. The locking piece 5 of the tool 301 is attached to the joist 4, and at that time, a gap T due to the bending angle is generated between the hanging piece 6 and the joist 4 (see FIG. 7). The heat insulating material 7 is pushed in and supported by the pedestal 8 so that the gap T disappears and the hanging piece 6, and thus the inner end edge 9 a of the support piece 9, contacts the joist 4. At that time, since the restoring force of the drooping piece 6 is generated outward, the drooping piece 6 plays a role of a leaf spring, and the side portion of the pressed heat insulating material 7 can be restrained well.
