First, the structure of the heat insulating material support 10 according to the first embodiment will be described. 1 to 3 are schematic views showing the configuration of the heat insulating material support 10 according to the first embodiment. The +X direction, the -X direction, the +Y direction, the -Y direction, the +Z direction, and the -Z direction used in the following description are the arrow directions shown in the drawing. Further, the "X direction" used in the following description is "+X direction or -X direction", "Y direction" is "+Y direction or -Y direction", and "Z direction" is "+Z direction or -Z direction". Means The X direction, the Y direction, and the Z direction correspond to the longitudinal direction of the joist 92 to which the heat insulating material support 10 is fixed, the lateral direction (width direction) of the joist 92, and the height direction of the joist 92, respectively. Further, the X direction, the Y direction, and the Z direction are orthogonal to each other.

The heat insulating material support tool 10 is a support tool that supports the heat insulating material, and as shown in FIG. 1, it is used by being fixed to a joist 92 (an example of a horizontal member) arranged under the floor. The heat insulating material to be supported by the heat insulating material support tool 10 is, for example, a heat insulating board formed of fibers such as glass wool or rock wool, or foamed with a resin material such as polystyrene, polyurethane, polyethylene, polyvinyl chloride, or phenol resin. A body-formed insulation board is used.

Specifically, as shown in FIG. 1, the heat insulating material support 10 includes a first contact portion 14A (an example of the contact portion) and a second contact portion 14B (an example of the one side contact portion). The first heat insulating material supporting portion 11, the second heat insulating material supporting portion 12, and the fixed portion 16 are provided.

The first contact portion 14A and the second contact portion 14B are portions that contact the lower surface of the joist 92, as shown in FIG. The first contact portion 14A and the second contact portion 14B are plate-shaped and have a thickness in the height direction (Z direction). In a state in which the first contact portion 14A and the second contact portion 14B are in contact with the lower surface of the joist 92 (hereinafter referred to as the contact state of the contact portions 14A and 14B), the heat insulating material support 10 is attached to the joist 92. Fixed.

As shown in FIG. 3, the first contact portion 14</b>A is a central portion (intermediate portion) in the Y direction of the heat insulating material support tool 10 and constitutes a +X direction side portion. The first contact portion 14A contacts the lower surface of the joist 92 with the entire width W of the joist 92 in the Y direction, and contacts the lower surface of the joist 92 with the length shorter than the total width W of the joist 92 in the X direction. .. Therefore, the first contact portion 14A has a rectangular shape having a length in the Y direction in a plan view.

The second contact portion 14B is provided on the −X direction side of the first contact portion 14A (an example of one side in the longitudinal direction of the joist 92) and is integrally provided with the first contact portion 14A and the second heat insulating material support portion 12. Has been. The second contact portion 14B has the notch 17 formed on the −X direction side with respect to the first contact portion 14A and on the +Y direction side with respect to the second contact portion 14B, so that the Y direction width has the first contact. It is narrower than the contact portion 14A.

As shown in FIGS. 1 and 2, the first heat insulating material support portion 11 is provided integrally with the first contact portion 14A and extends from the first contact portion 14A in the +Y direction. That is, in the contact state of the contact portions 14A and 14B, the first heat insulating material support portion 11 is outside (+Y) the side surface of the joist 92 from the first contact portion 14A on the +Y direction side (an example of one side surface). Project to the direction side). The first heat insulating material support portion 11 has a plate shape having a thickness in the height direction (Z direction).

Further, the length of the first heat insulating material support portion 11 in the X direction is the same as the length of the first contact portion 14A and the second contact portion 14B in the X direction, as shown in FIG. The width in the Y direction of the first heat insulating material support portion 11 is narrower than the length in the X direction of the first heat insulating material support portion 11. Therefore, the first heat insulating material support portion 11 has a rectangular shape having a length in the X direction in a plan view. And the 2nd heat insulating material support part 12 has a part of heat insulating material (for example, a corner part) mounted on the upper surface, and supports the said heat insulating material. The heat insulating material is arranged, for example, between the joists 92 arranged in the Y direction in plan view.

As shown in FIG. 3, the second heat insulating material support portion 12 is integrally provided with the first contact portion 14A and the second contact portion 14B, and from the first contact portion 14A and the second contact portion 14B. It extends to the −Y direction side. That is, in the contact state of the contact portions 14A and 14B, the second heat insulating material support portion 12 extends from the first contact portion 14A and the second contact portion 14B to -Y of the joist 92, as shown in FIG. The side surface on the direction side (an example of the other side surface) protrudes outward (−Y direction side). The second heat insulating material support portion 12 has a plate shape having a thickness in the height direction (Z direction).

Further, the X-direction length of the second heat insulating material support portion 12 is the same as the X-direction length of the combined first contact portion 14A and second contact portion 14B, as shown in FIG. The width of the second heat insulating material support portion 12 in the Y direction is slightly wider than the width of the first heat insulating material support portion 11 in the Y direction and is narrower than the length of the second heat insulating material support portion 12 in the X direction. Therefore, the second heat insulating material support portion 12 has a rectangular shape having a length in the X direction in a plan view. And the 2nd heat insulating material support part 12 has a part of heat insulating material (for example, a corner part) mounted on the upper surface, and supports the said heat insulating material.

As shown in FIG. 2, the fixed portion 16 is provided integrally with the first heat insulating material support portion 11, and as shown in FIG. It is erected with respect to the first heat insulating material support portion 11 at an example of one side in the longitudinal direction of 92 ). Specifically, the fixed portion 16 extends upward (+Z direction) from the −Y direction end of the −X direction side portion of the first heat insulating material support portion 11 including the −X direction end. Therefore, the length of the fixed portion 16 in the X direction is shorter than the length of the first heat insulating material support portion 11 in the X direction.

Then, the fixed portion 16 is fixed to the side surface of the joist 92 on the +Y direction side as shown in FIG. 2. Specifically, it is fixed to the joist 92 by a screw that is passed through a screw hole 16A (see FIG. 1) formed in the fixed portion 16. 2 and 3, the position fixed by the screw is indicated by the alternate long and short dash line.

The fixed portion 16 has a plate shape having a thickness in the Y direction. Further, the length of the fixed portion 16 in the Z direction is shorter than the length of the joist 92 in the height direction. Therefore, in the contact state of the contact portions 14A and 14B, the upper end of the fixed portion 16 is located below the upper end of the joist 92 (−Z direction side).

In the heat insulating material support tool 10, as shown in FIG. 5, a plurality of heat insulating material support tools 10 are arranged along the longitudinal direction (X direction) of the joist 92. In this case, in each heat insulating material support tool 10, the fixed portion 16 is fixed to the side surface of the joist 92 on the +Y direction side, and the heat insulating material support tool 10 has the same orientation with respect to the joist 92. In addition, for example, the side surfaces of the joist 92 on the +Y direction side and the side surfaces of the −Y direction side are alternately arranged so that the positions of the first heat insulating material support portion 11 and the second heat insulating material support portion 12 are switched. Each heat insulating material support 10 may be fixed.

The heat insulating material support 10 is manufactured (formed) by processing a metal plate 100 (see FIG. 4) which is rectangular in plan view and rectangular in plan view. As the metal plate 100, for example, it is possible to use various metal materials such as carbon steel whose surface is rust-proof coated, alloy steel such as stainless steel, and non-ferrous metal such as copper-nickel alloy.

The heat insulating material support 10 is specifically manufactured (formed) from the metal plate 100 as follows. That is, first, in the metal plate 100, the screw hole 16A is formed in the portion 116 to be the fixed portion 16. The portion 116 is a central portion (intermediate portion) in the Y direction of the metal plate 100 and constitutes a −X direction side portion. Next, the groove 102 having a predetermined width is formed in an L shape along the boundary between the +X direction end and the −Y direction end of the portion 116. As a result, the first contact portion 14A is formed on the +X direction side of the groove 102, and the second contact portion 14B is formed on the −Y direction side of the groove 102. Then, the boundary L between the portion 116 (the portion on the −X direction side with respect to the first contact portion 14A) and the first heat insulating material support portion 11 is bent to erect the portion 116 with respect to the first heat insulating material support portion 11. As a result, the fixed portion 16 is formed. In this way, the heat insulating material support 10 is manufactured (formed).

As shown in FIGS. 1 and 2, in the heat insulating material support 10, the first contact portion 14A and the second contact portion 14B are in contact with the lower surface of the joist 92, and the fixed portion 16 is in the joist 92. The fixed portion 16 is fixed to the joist 92 by the screw passed through the screw hole 16</b>A in the state of being abutted on the side surface of the. At this time, the upper end of the fixed portion 16 is located below the upper end of the joist 92. In this way, the heat insulating material support 10 is fixed (attached) to the joist 92.

[Operation and effect of heat insulating material support 10]
In the heat insulating material support tool 10, as shown in FIG. 2, in the contact state of the contact portions 14A and 14B, the upper end of the fixed portion 16 is located below the upper end of the joist 92, and in this state, The fixed portion 16 is fixed to the joist 92.

Here, in the heat insulating material support tool 800 (comparative example) shown in FIG. 6, the fixed portion 816 is fixed to the upper surface of the joist 92 while being placed on the upper surface of the joist 92. In addition, the heat insulating material support tool 800 has a contact portion 814 that extends downward from each of the +Y direction end and the −Y direction end of the fixed portion 816 and contacts each side surface of the joist 92, and each contact portion 814. And a heat insulating material support portion 813 protruding from the lower end to the outside.

Then, in the heat insulating material support tool 800, the fixed portion 816 is placed on the upper surface of the joist 92, and thus the upper portion of the joist 92 is protruded by the thickness of the fixed portion 816. When a plate member 94 such as a particle board is placed on the joist 92 provided with the heat insulating material support 800, a gap 96 is formed between the plate member 94 and the joist 92. When the gap 96 is formed between the plate member 94 and the joist 92, it causes a floor squeal and a bad walking feeling.

On the other hand, in the heat insulating material support 10 according to the present embodiment, as shown in FIG. 2, in the contact state of the contact portions 14A and 14B, the upper end of the fixed portion 16 is higher than the upper end of the joist 92. Located on the lower side. Therefore, when the fixed portion 16 is fixed to the joist 92, the fixed portion 16 does not protrude above the upper end of the joist 92. Therefore, as shown in FIG. 5, even if the plate member 94 such as a particle board is arranged on the joist 92 to which the heat insulating material support 10 is fixed, a gap 96 (see FIG. 6) is formed between the plate member 94 and the joist 92. ) Is suppressed. As a result, the ringing of the floor and the poor feeling of walking due to the gap 96 are suppressed.

Further, in the present embodiment, the boundary L between the portion 116 (the portion on the −X direction side with respect to the first contact portion 14A) of the metal plate 100 (see FIG. 4) and the first heat insulating material support portion 11 is bent to form a portion. The to-be-fixed part 16 is formed by making 116 stand upright with respect to the 1st heat insulating material support part 11. Thus, the fixed portion 16 can be provided integrally with the first heat insulating material support portion 11 by a simple process of bending the boundary between the portion 116 and the first heat insulating material support portion 11. Therefore, the shape is simpler and the number of steps in the manufacturing process is smaller than that in the case of manufacturing by bending a plurality of places or the case of manufacturing by joining a plurality of metal plates, and thus the manufacturing can be performed at low cost.

Further, in the present embodiment, when the heat insulating material support tool 10 is fixed to the joist 92, since the portion 116 arranged on the lower surface of the joist 92 is used as the fixed portion 16, the heat insulating material support tool 10 is fixed to the joist 92. In such a case, the areas of the first heat insulating material support portion 11 and the second heat insulating material support portion 12 can be increased as compared with the configuration in which the portion of the joist 92 projecting to the Y direction side is used as the fixed portion 16.

Further, in the present embodiment, not only the first abutting portion 14A but also the second abutting portion 14B abuts on the lower surface of the joist 92, so compared to a configuration in which only the first abutting portion 14A abuts, the heat insulating material support tool. 10 does not easily tilt with respect to the joists 92, and the posture of the heat insulating material support tool 10 with respect to the joists 92 is stable.

Further, in the present embodiment, since the fixed portion 16 of the heat insulating material support tool 10 is fixed to the side surface of the joist 92, the heat insulating material support tool 10 is fixed to the joist 92 as compared with the structure in which the heat insulating material support tool 10 is fixed to the lower surface of the joist 92. Easy to fix.

That is, in the contact state of the contact portions 24A to 24C, the second heat insulating material support portion 22 extends from the first contact portion 24A and the second contact portion 24B to -Y of the joist 92, as shown in FIG. The side surface on the direction side (an example of the other side surface) protrudes outward (−Y direction side). As shown in FIG. 9, the X-direction length of the second heat insulating material support portion 22 is the same as the X-direction length of the contact portions 24A to 24C combined. In other respects, the second heat insulating material support portion 22 is configured similarly to the second heat insulating material support portion 12 in the heat insulating material support tool 10 of the first embodiment.

As shown in FIG. 7, the first fixed portion 26 is integrally provided with the first heat insulating material support portion 21, and is on the −X direction side with respect to the first contact portion 24A (one side in the longitudinal direction of the joist 92). Of the first heat insulating material support portion 21. Specifically, the first fixed portion 26 extends upward (+Z direction) from the −Y direction end of the −X direction side portion including the −X direction end of the first heat insulating material support portion 21. Therefore, the X-direction length of the first fixed portion 26 is shorter than the X-direction length of the first heat insulating material support portion 21.

Then, as shown in FIG. 8, the first fixed portion 26 is fixed to the side surface of the joist 92 on the +Y direction side. Specifically, it is fixed to the joist 92 by a screw that is passed through a screw hole 26A (see FIG. 7) formed in the first fixed portion 26. Note that, in FIGS. 8 and 9, the position fixed by the screw is indicated by a chain line.

As shown in FIG. 7, the second fixed portion 28 is integrally provided with the second heat insulating material support portion 22, and is on the +X direction side (on the other side in the longitudinal direction of the joist 92) with respect to the first contact portion 24A. In one example), it stands upright with respect to the second heat insulating material support portion 22. Specifically, the second fixed portion 28 extends upward (+Z direction) from the +Y direction end of the +X direction side portion including the +X direction end of the second heat insulating material support portion 22.

Specifically, it is fixed to the joist 92 by a screw that is passed through a screw hole 28A (see FIG. 7) formed in the second fixed portion 28. Note that, in FIGS. 8 and 9, the position fixed by the screw is indicated by a chain line.

The first fixed portion 26 and the second fixed portion 28 (hereinafter, fixed portions 26, 28) are plate-shaped having a thickness in the Y direction. Further, the length of the fixed portions 26 and 28 in the Z direction is shorter than the length of the joist 92 in the height direction. Therefore, in the contact state of the contact portions 24A to 24C, the upper ends of the fixed portions 26 and 28 are located below the upper end of the joists 92 (−Z direction side). The lengths of the fixed portions 26 and 28 in the Z direction are the same.

As a result, the first fixed portion 26 is formed. Further, the boundary L2 between the portion 228 (the portion on the +X direction side with respect to the first contact portion 24A) and the second heat insulating material support portion 22 is bent so that the portion 228 stands up with respect to the second heat insulating material support portion 22. Thus, the second fixed portion 28 is formed. The above-mentioned notches 27 and 29 are formed by erecting the portions 226 and 228. In this way, the heat insulating material support tool 20 is manufactured (formed).

As shown in FIGS. 7 and 8, in the heat insulating material support 20, the contact portions 24A to 24C are in contact with the lower surface of the joist 92, and the fixed portions 26 and 28 are in contact with the side surfaces of the joist 92. In this state, the fixed portions 26 and 28 are fixed to the joists 92 by the screws passed through the screw holes 26A and 28A. At this time, the upper ends of the fixed portions 26 and 28 are located below the upper ends of the joists 92. In this way, the heat insulating material support 20 is fixed (attached) to the joist 92.

Then, the fixed portions 26 and 28 are fixed to the joist 92. Therefore, when the fixed portions 26 and 28 are fixed to the joist 92, the fixed portions 26 and 28 do not protrude above the upper end of the joist 92. Therefore, even if a plate material such as a particle board is arranged on the joist 92 to which the heat insulating material support tool 20 is fixed, formation of a gap between the plate material and the joist 92 is suppressed. As a result, the ringing of the floor and the poor feeling of walking due to the gap are suppressed.

The second fixed portion 28 is formed by standing upright with respect to the support portion 22.

Thus, the fixed portions 26 and 28 can be provided integrally with the first heat insulating material supporting portion 21 and the second heat insulating material supporting portion 22, respectively, by a simple process of bending the boundaries L1 and L2. Therefore, the shape is simple and the number of steps in the manufacturing process is small as compared with the case where the fixed portions 26 and 28 are formed by bending a plurality of places, or the case where a plurality of metal plates are joined and manufactured. It can be manufactured at low cost.

Furthermore, the X-direction length of the second heat insulating material support portion 42 is the same as the X-direction length of the contact portion 44, as shown in FIG. The width of the second heat insulating material support portion 42 in the Y direction is slightly wider than the width of the first heat insulating material support portion 41 in the Y direction and is narrower than the length of the second heat insulating material support portion 42 in the X direction. Therefore, the second heat insulating material support portion 42 has a rectangular shape having a length in the X direction in a plan view.

Therefore, the X-direction length of the second heat insulating material support portion 54 is shorter than the X-direction length of the contact portion 55. The X-direction lengths of the second heat insulating material support portions 52 and 54 are the same. And a part (for example, corner) of the heat insulating material is placed on the upper surface of the second heat insulating material supporting portions 52 and 54 to support the heat insulating material.

As shown in FIG. 19, the first fixed portion 56 is provided integrally with the abutting portion 55, and as shown in FIG. 21, between the pair of first heat insulating material support portions 51 and 53. It stands upright against the contact portion 55. Specifically, the first fixed portion 56 extends upward (+Z direction) from the +Y direction end of the central portion of the contact portion 55 in the X direction. Therefore, the X-direction length of the first fixed portion 56 is shorter than the X-direction length of the contact portion 55.

Then, as shown in FIG. 20, the first fixed portion 56 is fixed to the side surface of the joist 92 on the +Y direction side. Specifically, it is fixed to the joist 92 by a screw that is passed through a screw hole 56A (see FIG. 19) formed in the first fixed portion 56. 20 and 21, the position fixed by the screw is indicated by the alternate long and short dash line.

As shown in FIG. 19, the second fixed portion 58 is provided integrally with the abutting portion 55, and as shown in FIG. 21, between the pair of second heat insulating material support portions 52, 54. It stands upright against the contact portion 55. Specifically, the second fixed portion 58 extends upward (+Z direction) from the −Y direction end of the central portion of the contact portion 55 in the X direction. Therefore, the X-direction length of the second fixed portion 58 is shorter than the X-direction length of the contact portion 55.

Then, the second fixed portion 58 is fixed to the side surface of the joist 92 on the −Y direction side, as shown in FIG. Specifically, it is fixed to the joist 92 by a screw that is passed through a screw hole 58A (see FIG. 19) formed in the second fixed portion 58. 20 and 21, the position fixed by the screw is indicated by the alternate long and short dash line.

The Z-direction lengths of the first fixed portion 56 and the second fixed portion 58 (hereinafter, fixed portions 56, 58) are the Y-direction width of the first heat insulating material support portions 51, 53 and the second heat insulation, respectively. The width is the same as the width of the material support portions 52 and 54 in the Y direction, and is shorter than the length of the joist 92 in the height direction. Therefore, in the contact state of the contact portion 55, the upper ends of the fixed portions 56 and 58 are located below the upper end of the joist 92 (−Z direction side). The lengths of the fixed portions 56 and 58 in the Z direction are the same.

Further, the heat insulating material support tool 50 is manufactured (formed) by processing a flat and rectangular metal plate 500 (see FIG. 22) in plan view. As the metal plate 500, for example, various metal materials such as carbon steel having an anticorrosive coating on its surface, alloy steel such as stainless steel, and non-ferrous metal such as copper-nickel alloy can be used.

The heat insulating material support tool 50 is specifically manufactured (formed) from the metal plate 500 as follows. That is, first, in the metal plate 500, the screw hole 56A is formed in the portion 556 that becomes the first fixed portion 56, and the screw hole 58A is formed in the portion 558 that becomes the second fixed portion 58. The portion 556 is a central portion (intermediate portion) in the X direction of the metal plate 500 and constitutes a +Y direction side portion, and the portion 558 is a central portion (intermediate portion) in the X direction of the metal plate 200 and −Y. It constitutes the direction side part.

Next, grooves 501 and 503 having a predetermined width are formed in the −Y direction along the boundaries between the +Y direction end of the metal plate 500 and the +X direction end and the −X direction end of the portion 556. As a result, the first heat insulating material support portion 51 is formed on the +X direction side of the groove 501, and the first heat insulating material support portion 53 is formed on the −X direction side of the groove 503. Further, grooves 502 and 504 having a predetermined width are formed in the +Y direction along the boundaries between the −Y direction end of the metal plate 500 and the +X direction end and the −X direction end of the portion 558. As a result, the second heat insulating material support portion 52 is formed on the +X direction side of the groove 502, and the second heat insulating material support portion 54 is formed on the −X direction side of the groove 504.

Then, the first fixed portion 56 is formed by bending the boundary L1 between the portion 556 and the contact portion 55 and erecting the portion 556 with respect to the contact portion 55. In addition, the second fixed portion 58 is formed by bending the boundary L2 between the portion 558 and the contact portion 55 and erecting the portion 558 with respect to the contact portion 55. In this way, the heat insulating material support tool 50 is manufactured (formed).

As shown in FIGS. 19 and 20, in the heat insulating material support tool 50, the contact portion 55 is in contact with the lower surface of the joist 92, and the fixed portions 56 and 58 are in contact with the side surfaces of the joist 92. In this state, the fixed portions 56 and 58 are fixed to the joists 92 by the screws passed through the screw holes 56A and 58A. At this time, the upper ends of the fixed portions 56 and 58 are located below the upper ends of the joists 92. In this way, the heat insulating material support tool 50 is fixed (attached) to the joist 92.

[Function and effect of heat insulating material support 50]
In the heat insulating material support tool 50, as shown in FIG. 20, in the contact state of the contact portion 55, the upper ends of the fixed portions 56 and 58 are located below the upper end of the joist 92, and in this state, The fixed portions 56 and 58 are fixed to the joist 92. Therefore, when the fixed portions 56 and 58 are fixed to the joist 92, the fixed portions 56 and 58 do not protrude above the upper end of the joist 92. Therefore, even if a plate material such as a particle board is arranged on the joist 92 to which the heat insulating material support 50 is fixed, formation of a gap between the plate material and the joist 92 is suppressed. As a result, the ringing of the floor and the poor feeling of walking due to the gap are suppressed.

Further, in the present embodiment, the boundary L1 between the portion 556 of the metal plate 500 (see FIG. 22) and the contact portion 55 is bent, and the portion 556 is erected with respect to the contact portion 55, so that the first cover The fixed portion 56 is formed. In addition, the second fixed portion 58 is formed by bending the boundary L2 between the portion 558 and the contact portion 55 and erecting the portion 558 with respect to the contact portion 55. Thus, the fixed portions 56 and 58 can be provided integrally with the abutting portion 55 by a simple process of bending the boundaries L1 and L2. Therefore, the shape is simple and the number of steps in the manufacturing process is small as compared with the case where the fixed portions 56 and 58 are formed by bending a plurality of places or the case where a plurality of metal plates are joined and manufactured. It can be manufactured at low cost.

In addition, in the present embodiment, when the heat insulating material support tool 50 is fixed to the joist 92, the portions 556 and 558 of the joist 92 projecting in the Y direction are used as the fixed portions 56 and 58. When fixed to the joist 92, the area of the contact portion 55 can be increased as compared with the configuration in which the portions arranged on the lower surface of the joist 92 are used as the fixed portions 56 and 58.

Further, in the present embodiment, since the fixed portions 26 and 28 are fixed to the side surfaces on both sides of the joist 92, compared to the configuration in which a single fixed portion is fixed to one side surface of the joist 92. The fixing strength of the heat insulating material support tool 20 to the joist 92 is high.
