Summary of the Invention

Problems to be Solved by the Invention

[0005] Here, in order to improve the heat insulation performance of the roof, for example, it is conceivable to attach a heat insulating material to a support member using the ceiling material construction joint material described in Patent Document 1.

[0006] However, when attaching a heat insulating material to a pitched roof, it is necessary to attach the ceiling material construction joint material described in Patent Document 1 to an inclined support member, but the ceiling material construction joint material described in Patent Document 1 is not assumed to be attached to a pitched roof.

[0007] The object of the present invention is to provide a holding member that can efficiently arrange insulation material along the roof underlayment of a sloped roof, and a sloped roof of a building equipped therewith. [Means for solving the problem]

[0008] To solve the above problems, the first invention provides a holding member for holding thermal insulation material, which is attached to a predetermined mounting target portion of a support member extending in a predetermined inclination direction to support a roof base material in a sloping roof of a building, and is positioned below the mounting target portion and along the inclination direction, comprising: a mounting portion attached to the mounting target portion; an extension portion extending downward from the mounting portion along an extension direction perpendicular to the inclination direction when the mounting portion is attached to the mounting target portion; and a holding portion provided on the extension portion and for holding the thermal insulation material, wherein the mounting portion has a mounting portion that is placed on an upward-facing surface of the mounting target portion so as to entrust the load of the holding member to the support member; and a contact portion that abuts against a downward-facing surface of the mounting target portion to restrict the rotation of the holding member so as to cause the extension portion to change from a position along the extension direction to a position along the vertical direction due to the weight of the thermal insulation material when the mounting portion is placed on the upward-facing surface.

[0009] According to the present invention, the load of the holding member can be transferred to the support member by placing the mounting portion on the upward surface of the support member. In this state, when the heat insulating material is held by the holding portion, the load of the heat insulating material is applied to the holding member, and as a result, the holding member attempts to rotate with the uppermost part in the inclined direction of the area in contact with the upward surface of the mounting portion (the part that becomes the pivot point for rotation in the mounting portion: hereinafter referred to as the pivot point) as the pivot point. In the present invention, in order to restrict the rotation of the holding member, a contact portion is provided that abuts against the downward-facing surface of the mounting target portion, so that the rotation of the holding member can be effectively restricted.

[0010] Therefore, according to the present invention, insulation material can be efficiently arranged along the roof underlayment of a sloped roof.

[0011] The second invention is preferable in the first invention, where the contact portion is located downward in the inclination direction from the portion that serves as the pivot point for rotation in the mounting portion when the mounting portion is attached to the mounting target portion.

[0012] According to the second invention, since the contact portion is located in the mounting portion and is positioned downward in the inclined direction from the portion that serves as the pivot point for the rotation, the rotation of the holding member can be more effectively restricted.

[0013] The third invention is that, in the first or second invention, when the mounting portion is attached to the mounting target portion, it is preferable that the contact portion is provided within the range of the mounting portion described above in the inclined direction.

[0014] In the third invention, the contact portion is provided within the range of the mounting portion in the inclined direction; that is, a part of the mounting portion (the part that acts as the pivot point) can be positioned on both sides of the contact portion in the inclined direction. Therefore, not only can the holding member be attached to the support member with its rotation restricted in a specific position as described above, but it can also be attached to the support member with its rotation restricted even when the position is reversed in the inclined direction from a specific position. Therefore, the ease of installation can be improved compared to the case where the mounting position of the holding member is fixed to one position.

[0015] The fourth invention is that, in any one of the first to third inventions, the support member has a mounting target portion arranged along the inclination direction and having an upward surface and a downward surface, and a projection portion that protrudes upward along the extension direction from the edge of the mounting target portion in a lateral direction perpendicular to the inclination direction and the extension direction, and the mounting portion preferably has a connecting portion that connects the mounting target portion and the contact portion so as to enclose the projection portion, with the mounting target portion sandwiched in the extension direction by the mounting portion and the contact portion.

[0016] According to the fourth invention, the mounting portion and the contact portion enclose the protruding portion with the connecting portion, and the mounting portion is sandwiched in the extending direction between them, thereby preventing the protruding portion from coming out from between the mounting portion and the contact portion, and allowing the mounting portion to be attached to the mounting portion. Therefore, when the mounting portion is attached to the mounting portion, it is possible to prevent the mounting portion from moving laterally and falling off the support member.

[0017] The fifth invention is that, in the fourth invention, the mounting portion preferably has an introduction end that extends from the mounting portion and terminates thereafter, such that it moves away from the connecting portion in the lateral direction and away from the contact portion in the extending direction.

[0018] According to the fifth invention, the introduction end is inclined such that the distance between the introduction end and the contact portion increases as it moves away from the connecting portion in the lateral direction. Therefore, when attaching the part to be attached to the part to be attached, the protruding portion can be guided between the mounting portion and the contact portion. Consequently, the ease of installation of the holding member to the support member can be improved compared to the case where the protruding portion is inserted between the mounting portion and the contact portion which are in close contact with each other.

[0019] The sixth invention is that, in the fourth or fifth invention, the connecting portion preferably has a shape that tapers upward in the extension direction as it moves away from the contact portion in the lateral direction.

[0020] According to the sixth invention, the tip of the protruding portion inserted between the mounting portion and the contact portion can be guided laterally along the tapered shape of the connecting portion, and the protruding portion can be positioned laterally by inserting its tip into the tapered portion of the connecting portion. Therefore, the holding member attached to the support member can be positioned laterally.

[0021] The seventh invention is in the first or second invention, wherein the support member has a base portion disposed along the inclined direction and having the downward surface, and a protruding portion protruding upward along the extending direction from an edge portion of the base portion in a lateral direction orthogonal to the inclined direction and the extending direction and having the upward surface, and the attached portion has a connecting portion connecting the placing portion and the abutting portion so as to be disposed along a side surface of the protruding portion in a state where the base portion and the protruding portion are sandwiched in the extending direction by the placing portion and the abutting portion, and a sandwiching portion sandwiching the protruding portion in the lateral direction between the connecting portion and the sandwiching portion.

[0022] According to the seventh invention, since the placing portion is placed on the upward surface of the protruding portion and the abutting portion abuts against the downward surface of the base portion, the protruding portion can be sandwiched between the connecting portion and the sandwiching portion, so that the holding member can be positioned in the lateral direction with respect to the support member while restricting the rotation of the holding member due to the load of the heat insulating material. Further, the present invention provides a pitched roof of a building, which includes a roof base material, a pair of support members extending parallel to each other along a predetermined inclined direction and supporting the roof base material, a pair of holding members of the first to seventh inventions respectively attached to predetermined attachment target portions in each of the support members, and a heat insulating material held by the pair of holding members so as to straddle between the pair of support members.

Effect of the Invention

[0023] When the holding member of the first embodiment of the present invention is applied, it is a front sectional view showing a part of a pitched roof of a building, with a part of the heat insulating material omitted. According to the present invention, it is possible to provide a holding member capable of efficiently arranging a heat insulating material along a roof base material of a pitched roof.

[0025] Embodiments of the present invention will be described below with reference to the attached drawings. Note that the following embodiments are examples that embody the present invention and are not intended to limit the technical scope of the present invention.

[0026] Figure 1 is a front cross-sectional view showing a portion of the sloping roof of a building to which the retaining member 1 according to the first embodiment of the present invention is applied, with a portion of the insulation material omitted. Figure 2 is a cross-sectional view taken along line II-II in Figure 1.

[0027] Referring to Figures 1 and 2, the sloping roof 30 of the building comprises a roof base material 31, a plurality of support members 32 (one support member 32 is shown in Figures 1 and 2) that extend parallel to each other along a predetermined inclination direction D1 and support the roof base material 31, a plurality of retaining members 1 attached to predetermined mounting targets on each support member 32, and a plurality of heat insulating materials 33 that straddle a pair of adjacent support members 32 and are held by the retaining members 1 so as to be arranged along the inclination direction D1.

[0028] The roof underlayment 31 includes a roof decking board provided on the support member 32 and roofing felt provided on the roof decking board.

[0029] Multiple support members 32 extend in the inclination direction D1 and are arranged parallel to each other. Each support member 32 is made of steel. Specifically, each support member 32 comprises a pair of C-shaped steel sections 34 and connecting members (e.g., bolts; not shown) that connect the C-shaped steel sections 34 to each other. The C-shaped steel section 34 has a web 34a, a pair of flanges (corresponding to inclined sections) 34b extending from both edges of the web 34a and facing each other, and lips (corresponding to protruding sections) 34c projecting from the ends of each flange 34b toward the opposing flange 34b. The pair of C-shaped steel sections 34 are connected to each other by connecting members with their respective flange back surfaces (the surfaces facing away from the flanges 34b) facing each other. The support member 32 is fixed to the building frame (not shown) with the flange 34b positioned along the inclination direction D1, and the lips 34c projecting outwards from the edge of the flange 34b in the inclination direction D1, the extension direction D2 perpendicular to the inclination direction D1, and the lateral direction D3 perpendicular to the inclination direction D1, so that each lip 34c faces each other (upwards).

[0030] The insulation material 33 is held from both sides by a holding member 1 (described later) attached to each of the two adjacent support members 32, thereby extending across the two adjacent support members 32 and along the inclined direction D1. Furthermore, the insulation material 33 is formed in a plate shape from a material with higher rigidity than fibrous insulation materials such as glass wool. For example, the insulation material 33 is made of foamed urethane.

[0031] The retaining member 1 is attached to the flange 34b (corresponding to a predetermined mounting target portion) of the support member 32 and is intended to hold the heat insulating material 33 so as to be positioned below the flange 34b and along the inclination direction D1. Specifically, the retaining member 1 comprises a mounting portion 2 that is attached to the flange 34b, an extension portion 3 that extends downward from the mounting portion 2 along the extension direction D2 when the mounting portion 2 is attached to the flange 34b, and a retaining portion 4 provided on the extension portion 3 and for holding the heat insulating material 33.

[0032] Figures 3 and 4 are perspective views of the retaining member shown in Figure 2. Figures 5 and 6 show the procedure for attaching the mounting portion 2 of the retaining member 1 shown in Figure 2 to the flange 34b.

[0033] Referring to Figures 2 to 6, the mounting portion 2 includes a mounting portion 2a that is placed on the upward-facing surface 34b1 of the flange 34b, a contact portion 2b that is positioned below the downward-facing surface 34b2 of the flange 34b when the mounting portion 2a is placed on the upward-facing surface 34b1, a connecting portion 2c that connects the mounting portion 2a and the contact portion 2b so as to enclose the lip 34c when the flange 34b is sandwiched between the mounting portion 2a and the contact portion 2b in the extension direction D2, and an introduction end portion 2d that extends from the mounting portion 2a in a direction away from the connecting portion 2c in the lateral direction D3 and terminates.

[0034] The mounting portion 2a is placed on the upward surface 34b1 of the flange 34b so as to transfer the load of the holding member 1 to the support member 32. Specifically, the mounting portion 2a corresponds to the corner formed between the connecting portion 2c and the introduction end portion 2d, which will be described later.

[0035] The contact portion 2b is provided to contact the downward surface 34b2 when the mounting portion 2a is placed on the upward surface 34b1, and to restrict the rotation of the holding member 1 so that the extension portion 3 changes from a position along the extension direction D2 to a position along the vertical direction due to the weight of the heat insulating material 33. Specifically, as shown in Figure 7, when the heat insulating material 33 is held by the holding member 1, the holding member 1 attempts to rotate around the uppermost part P1 of the mounting portion 2a in the inclination direction D1 (hereinafter referred to as the pivot point P1). When the mounting portion 2 is attached to the support member 32, the contact portion 2b contacts the downward surface 34b2 at a position located below the pivot point P1 in the inclination direction D1 on the mounting portion 2a. Therefore, the rotation of the holding member 1 around the pivot point P1 can be effectively restricted by the contact portion 2b.

[0036] Furthermore, the contact portion 2b is located within the range R1 of the mounting portion 2a in the inclination direction D1 when the mounting portion 2 is attached to the flange 34b. Therefore, even if the holding member 1 is rotated 180° around the axis along the extension direction D2 (reversed in the inclination direction D1), the pivot point P1 can be positioned on the contact portion 2b in the inclination direction D1. Consequently, even if, for example, the holding member 1 reversed in the inclination direction D1 is attached to the adjacent support member 32, the rotation of the holding member 1 around the pivot point P1 can be suppressed.

[0037] Furthermore, the contact portion 2b faces the mounting portion 2a with a gap smaller than the thickness of the flange 34b, so as to sandwich the flange 34b between itself and the mounting portion 2a. In this embodiment, as shown in Figure 5, the mounting portion 2a and the contact portion 2b are in contact with each other in the state before attachment to the support member 32.

[0038] Referring to Figures 2 to 4, the introduction end portion 2d extends from the mounting portion 2a and terminates, moving away from the connecting portion 2c in the lateral direction D3 and away from the contact portion 2b in the extension direction D2.

[0039] The connecting portion 2c has a shape that tapers upward in the extension direction D2. Specifically, the connecting portion 2c has a first portion 2c1 that extends upward in the extension direction D2 from the end of the contact portion 2b located on the extension portion 3 side, and a second portion 2c2 that extends from the upper end of the first portion 2c1 to the mounting portion 2a in the lateral direction D3, moving away from the first portion 2c1 and approaching the contact portion 2b. In this embodiment, as shown in Figures 3 and 4, a pair of first portions 2c1 are provided on both sides of the contact portion 2b in the inclination direction D1, and the second portion 2c2 has a pair of extension portions (not shown) extending from each first portion 2c1 and a connecting portion (not shown) that connects the tips of both extension portions.

[0040] As described above, the mounting portion 2 has an introduction end portion 2d and a connecting portion 2c, and therefore can be easily and reliably attached to the support member 32, as shown in Figures 5 and 6.

[0041] When attaching the mounting portion 2 to the support member 32, first, as shown in Figure 5, the mounting portion 2 is pressed against the lip 34c from above so that the lip 34c fits between the introduction end portion 2d and the contact portion 2b.

[0042] In this pressed state, by rotating the holding member 1 counterclockwise around the tip of the lip 34c as shown in Figure 5, the lip 34c is inserted inside the connecting portion 2c as the mounting portion 2a and the contact portion 2b separate from each other, accompanied by the elastic deformation of the connecting portion 2c, as shown in Figure 6. Note that in Figure 6, for convenience, the holding member 1 is shown in a state where it has not undergone elastic deformation.

[0043] Furthermore, by rotating the holding member 1 counterclockwise, as shown in Figure 2, the lip 34c is inserted all the way into the connecting portion 2c, and the flange 34b is sandwiched between the mounting portion 2a and the contact portion 2b.

[0044] Referring to Figures 2 to 4, the extension portion 3 is a plate-like portion that is arranged along a plane extending in the inclination direction D1 and the extension direction D2 when the mounting portion 2 is attached to the support member 32. In this embodiment, the thickness dimension of the extension portion 3 in the lateral direction D3 is smaller than the plate thickness dimension of the steel material constituting the C-shaped steel 34 of the support member 32.

[0045] The holding portion 4 has six clamping pieces 5a, 5b, 5c, 6a, 6b, 6c that clamp the thermal insulation material 33 in the extending direction D2 when the mounting portion 2 is attached to the support member 32. Clamping pieces 5a, 5b, 5c extend from the extending portion 3 toward one direction in the lateral direction D3, and clamping pieces 6a, 6b, 6c extend from the extending portion 3 toward the other direction in the lateral direction D3. Specifically, clamping piece 5a is provided at the lower end of the extending portion 3, clamping piece 5b is provided on top of clamping piece 5a, and clamping piece 5c is provided on top of clamping piece 5b. The spacing between clamping pieces 5a and 5b, and between clamping pieces 5b and 5c are set to be spacings that allow the thermal insulation material 33 to be clamped, specifically, to be equal to or smaller than the thickness of the thermal insulation material 33 in the extending direction D2. Furthermore, the surfaces of the clamping pieces 5a, 5b, and 5c that face each other (surfaces for clamping the heat insulating material 33) are each arranged along the inclination direction D1. In addition, the clamping pieces 5a and 5c each have a leaf spring portion (not shown) for applying a biasing force to the heat insulating material 33 in order to securely clamp the heat insulating material 33. More specifically, the clamping piece 5a has a flat plate portion (not shown) and a leaf spring portion (not shown) extending along the lateral direction D3, while the clamping piece 5c has only a leaf spring portion. The clamping pieces 6a, 6b, and 6c have a configuration that is symmetrical to the clamping pieces 5a, 5b, and 5c in the lateral direction, so their description is omitted. Note that since the holding member 1 in this embodiment is formed by bending a single metal plate, the positions of the clamping pieces 5a and 6a in the inclination direction D1, and the positions of the clamping pieces 5c and 6c in the inclination direction D1 are different from each other. For similar reasons, the sizes of clamping pieces 5b and 6b are different.

[0046] In the holding portion 4, the ends of the insulation material 33 are clamped in the thickness direction of the insulation material 33 between clamping pieces 5a and 5b, between clamping pieces 5b and 5c, between clamping pieces 6a and 6b, and between clamping pieces 6b and 6c. The surfaces of the clamping pieces 5a-5c and 6a-6c for clamping the insulation material 33 are arranged along the inclination direction D1 when the mounting portion 2 is attached to the support member 32, so that the insulation material 33 can be positioned along the roof base material 31 (inclination direction D1) by the holding portion 4.

[0047] Furthermore, a gap in the extending direction D2 is provided between the clamping pieces 5c and 6c and the contact portion 2b to accommodate the brace B (see Figure 2) that is attached to the support member 32 when the mounting portion 2 is attached to the support member 32.

[0048] As described above, according to the embodiment, as shown in Figure 2, the load of the holding member 1 can be transferred to the support member 32 by placing the mounting portion 2a on the upward surface 34b1 of the flange 34b. In this state, when the heat insulating material 33 is held by the holding portion 4, the load of the heat insulating material 33 is applied to the holding member 1, and as a result, as shown in Figure 7, the holding member 1 attempts to rotate with the uppermost pivot point P1 in the inclined direction among the areas of the mounting portion 2a that are in contact with the upward surface 34b1 as the pivot point. In the embodiment, since the contact portion 2b is provided at a position located downward in the inclined direction D1 from the pivot point P1, the rotation of the holding member 1 can be effectively restricted by the contact portion 2b contacting the downward surface 34b2 of the support member 32.

[0049] Therefore, the insulation material 33 can be efficiently placed along the roof underlayment material 31 of the sloped roof 30.

[0050] In the above embodiment, the contact portion 2b is provided within the range R1 (Figure 7) of the mounting portion 2a in the inclination direction D1. That is, a part of the mounting portion 2a (the portion that becomes the pivot point P1) can be positioned on both sides of the contact portion 2b in the inclination direction D1. Therefore, for example, the retaining member 1 can be attached to the flange 34b (the C-shaped steel 34 on the left side of Figure 2) while restricting its rotation in the posture shown in Figure 2, and it can also be attached to the flange 34b (for example, the C-shaped steel 34 on the right side of Figure 2) while restricting its rotation even when the posture is reversed from a specific posture to the inclination direction D1. Therefore, the ease of installation can be improved compared to the case where the mounting posture of the retaining member 1 is fixed to one position.

[0051] According to the first embodiment, as shown in Figure 2, the mounting portion 2a and the contact portion 2b sandwich the flange 34b in the extending direction D2 with the lip 34c enclosed by the connecting portion 2c, thereby preventing the lip 34c from coming out from between the mounting portion 2a and the contact portion 2b, and allowing the mounting portion 2 to be attached to the flange 34b. Therefore, when the mounting portion 2 is attached to the flange 34b, it is possible to prevent the mounting portion 2 from moving laterally and falling off the support member 32.

[0052] According to the first embodiment, the introduction end 2d is inclined such that the distance between the introduction end 2d and the contact portion 2b increases as it moves away from the connecting portion 2c in the lateral direction D3. Therefore, when attaching the mounting portion 2 to the flange 34b, the lip 34c can be guided between the mounting portion 2a and the contact portion 2b. Consequently, the ease of installation of the holding member 1 to the support member 32 can be improved compared to the case where the lip 34c is inserted between the mounting portion 2a and the contact portion 2b, which are in close contact with each other.

[0053] According to the first embodiment, the tip of the lip 34c inserted between the mounting portion 2a and the contact portion 2b can be guided laterally in the direction D3 along the tapered shape of the connecting portion 2c, and the lip 34c can be positioned laterally in the direction D3 by the tip of the lip 34c being inserted into the tapered portion of the connecting portion 2c. Therefore, the retaining member 1 attached to the flange 34b can be positioned laterally in the direction D3.

[0054] The configuration of the second embodiment of the present invention will be described below with reference to Figures 8 and 9. The differences between the second embodiment and the first embodiment will be primarily described. Figure 8 is a diagram corresponding to Figure 2 on a sloping roof of a building to which the retaining member according to the second embodiment of the present invention is applied. Figure 9 is a perspective view of the retaining member shown in Figure 8.

[0055] The holding member 11 according to the second embodiment is attached to the flange 35a (corresponding to the mounting target portion) of the support member 35 which extends in the inclined direction D1, and is for holding the heat insulating material 33 so as to be positioned below the flange 35a and along the inclined direction D1.

[0056] Unlike the first embodiment, the support member 35 is made of an H-shaped steel. Specifically, the support member 35 has a pair of upper and lower flanges 35a extending along the inclination direction D1, and a web 35b extending in an extension direction D2 perpendicular to the inclination direction D1 and connecting the intermediate portions of the flanges 35a.

[0057] The retaining member 11 includes a mounting portion 12 that is attached to the flange 35a, an extension portion 13 that extends downward from the mounting portion along the extension direction D2 when the mounting portion 12 is attached to the flange 35a, and a retaining portion 14 provided on the extension portion 13 and holding the heat insulating material 33.

[0058] The mounting portion 12 includes a mounting portion 12a that rests on an upward-facing surface 35a1 of the flange 35a so as to transfer the load of the holding member 11 to the support member 35, and a contact portion 12b that abuts against a downward-facing surface 35a2 of the flange 35a to restrict the rotation of the holding member 11 so that the extension portion 13 changes from a position along the extension direction D2 to a position along the vertical direction due to the weight of the heat insulating material 33 when the mounting portion 12a is resting on the upward-facing surface 35a1. As in the first embodiment, the distance between the contact portion 12b and the mounting portion 12a is set to a distance that allows the flange 35a to be clamped, specifically, to be equal to or smaller than the thickness dimension of the flange 35a. Specifically, in the second embodiment, the distance between the contact portion 12b and the mounting portion 12a is set to be smaller than the thickness of the flange 35a. On the other hand, unlike the first embodiment, the width dimensions of the mounting portion 12a and the contact portion 12b along the inclination direction D1 are set to be substantially the same.

[0059] Furthermore, the mounting portion 12 includes a connecting portion 12c that connects the mounting portion 12a and the contact portion 12b so as to enclose the tip of the flange 35a when the flange 35a is sandwiched in the extension direction D2 by the mounting portion 12a and the contact portion 12b, and an introduction end portion 12d that extends from the mounting portion 12a and terminates so as it moves away from the connecting portion 12c in the lateral direction D3 perpendicular to the inclination direction D1 and the extension direction D2, it moves away from the contact portion 12b in the extension direction D2. This differs from the first embodiment in that the connecting portion 12c encloses the tip of the flange 35a instead of the lip 34c.

[0060] Furthermore, unlike the first embodiment, the mounting portion 12 has a leaf spring portion 12e for applying a biasing force to the upward surface 35a1 of the flange 35a when the mounting portion 12a is placed on the upward surface 35a1. This stabilizes the clamping state of the flange 35a by the mounting portion 12a and the contact portion 12b.

[0061] Furthermore, in the second embodiment, unlike the first embodiment, the contact portion 12b also serves as part of the holding portion 14. Also, unlike the first embodiment, the holding portion 14 in the second embodiment extends only in one direction from the extension portion 13 in the lateral direction D3, rather than extending in both directions.

[0062] Specifically, the holding portion 14 has clamping pieces 15a and 15b for clamping the thermal insulation material 33 in the extending direction D2 when the mounting portion 12 is attached to the flange 35a. The clamping piece 15a is provided at the lower end of the extending portion 13, and the clamping piece 15b is provided on top of the clamping piece 15a. Furthermore, in the second embodiment, the contact portion 12b is provided on top of the clamping piece 15b. The distance between the clamping piece 15a and the clamping piece 15b, and the distance between the contact portion 12b and the clamping piece 15b are set to a distance that allows the thermal insulation material 33 to be clamped, specifically, to be equal to or smaller than the thickness dimension of the thermal insulation material 33.

[0063] Furthermore, as described above, since the contact portion 12b is also used as part of the holding portion 14, the mounting portion 12 is further provided with a leaf spring portion 12f that protrudes downward from the contact portion 12b and applies a downward biasing force to the heat insulating material 33. The presence of the leaf spring portion 12f allows the heat insulating material 33 to be stably held between the contact portion 12b and the clamping piece 15b.

[0064] The configuration of the third embodiment of the present invention will be described below with reference to Figures 10 to 12. The differences between the third embodiment and the second embodiment will be primarily described. Figure 10 is a diagram corresponding to Figure 2 in a sloping roof of a building having a holding member according to the third embodiment of the present invention. Figure 11 is a side view showing one of the holding members shown in Figure 10 separated from the support member. Figure 12 is a plan view showing an enlarged view of the holding portion of the holding member shown in Figure 11.

[0065] Unlike the holding member 1 of the first embodiment, the holding member 21 according to the third embodiment has a mounting portion 22 that is attached to the lip 34c and flange 34b (which correspond to the mounting target portion) so as to rest on the upward surface 34c1 of the lip (projection portion) 34c of the support member 32 and abut against the downward surface 34b2 of the flange (base portion) 34b.

[0066] Specifically, the mounting portion 22 includes a mounting portion 22a that rests on the upward surface 34c1 of the lip 34c, a contact portion 22b positioned below the downward surface 34b2 of the flange 34b when the mounting portion 22a is resting on the upward surface 34c1, a connecting portion 22c that connects the mounting portion 22a and the contact portion 22b so as to be positioned along the side surface of the lip 34c while the lip 34c and flange 34b are sandwiched between the mounting portion 22a and the contact portion 22b, and a clamping portion 22d that clamps the lip 34c in the lateral direction D3 between itself and the connecting portion 22c. The mounting portion 22a has a lateral dimension D3 that is longer than the upward surface 34c1. The connecting portion 22c extends in the extension direction D2 from the end of the mounting portion 22a to the end of the contact portion 22b. The clamping portion 22d has a clamping portion 22d1 that extends downward in the extension direction D2 so as to approach the connecting portion 22c from the end of the mounting portion 22a opposite to the connecting portion 22c in the lateral direction D3, and an introduction end portion 22d2 that extends downward in the extension direction D2 so as to move away from the connecting portion 22c from the clamping portion. Similar to the embodiment described above, since it has an introduction end portion 22d2, the lip 34c and flange 34b can be efficiently inserted between the introduction end portion 22d2 and the connecting portion 22c.

[0067] Furthermore, unlike the extensions 3 and 13 of the above-described embodiment which position the holding portions 4 and 14 directly below the extension direction D2 of the mounting portions 2 and 12, the holding member 21 according to the third embodiment has an extension 23 which position the holding portion 24 at a position separated from the mounting portion 22 in the lateral direction D3.

[0068] The extension portion 23 according to the third embodiment is for positioning the holding portion 24 at the central position in the lateral direction D3 of the support member 32, that is, between two C-shaped steel sections 34 connected to each other. Specifically, the extension portion 23 has a base portion 23a extending downward in the extension direction D2 from the mounting portion 22, a lateral extension portion 23b extending in the lateral direction D3 from the tip of the base portion 23a, and a tip portion 23c extending downward in the extension direction D2 from the lateral extension portion 23b.

[0069] Furthermore, in the third embodiment, unlike the holding portions 4 and 14 which sandwich the thermal insulation material 33 in the extension direction D2 as in the embodiments described above, the holding member 21 holds the thermal insulation material 33 by being inserted into the thermal insulation material (e.g., foamed urethane) 33 in the lateral direction D3. Specifically, the holding member 21 has a pair of upper and lower holding portions 24 that extend from the tip portion 23c of the extension portion 23 toward the base portion 23a in the lateral direction D3. As shown in Figure 12, the holding portions 24 have a tapered planar shape for inserting into the thermal insulation material 33. According to the third embodiment, the lip 34c can be sandwiched between the connecting portion 22c and the clamping portion 22d with the mounting portion 22a placed on the upward surface 34c1 of the lip 34c and the contact portion 22b in contact with the downward surface 34b2 of the flange 34b. Therefore, the holding member 21 can be positioned in the lateral direction D3 relative to the support member 32 while restricting the rotation of the holding member 21 due to the load of the heat insulating material 33.

[0070] It should be noted that the present invention is not limited to the embodiments described above, and for example, the following embodiments may also be adopted.

[0071] In the holding members 1 and 11 having holding portions 4 and 14 that hold the thermal insulation material 33 by sandwiching the thermal insulation material 33 in the extending direction, as in the first and second embodiments, it is sufficient that at least one pair of holding portions 4 and 14 are provided that are separated in the extending direction D2 by a distance corresponding to the thickness direction of the thermal insulation material 33.

[0072] On the other hand, in the third embodiment, in a holding member 21 having a holding portion 24 that holds the heat insulating material 33 by being inserted into the heat insulating material 33, it is sufficient that at least one holding portion 24 is provided.

[0073] Furthermore, while the first to third embodiments illustrate support members made of steel, the support members may also be made of wood.
