Description

[Technical field]

[0001] The present invention relates to a roof support that constitutes a roof constructed mainly with folded roof panels of the fastening type and fitting type using fitting cap material, and to the folded roof. [Background technology]

[0002] In recent years, roofs (including steeply sloping walls, etc.) using various metal folded-plate roofing materials have been widely used. This type of roofing plate is fixed to structural materials such as purlins and furring strips via roof supports, and the connecting structure between the roofing plates includes a fastening type and a fitting type using a cap material, and these types are widely used. In addition, there are also folded-plate roofs that are constructed at a steep slope to have a roughly wall-like shape, and many such folded-plate roofs exist.

[0003] In roofs constructed with these roof fastening type roof panels, the roof panels are connected to each other via retaining clips that are fixed to the tops of the roof fastening parts and the roof support. In other words, roof fastening type roofs are configured so that the roof panels are fixed to the roof support only by connecting the retaining clips to the roof fastening parts of the roof panels.

[0004] However, when negative pressure from the wind acts on each roof panel, the larger the flat surface, the greater the negative external pressure force that acts on the roof panel, and the roof panel is lifted upward. In recent years, due to changes in the natural environment, the number of large and powerful typhoons has increased, and their scale has also tended to become stronger.

[0005] As a result, there has been an increasing trend of roofs being blown away by the roof brackets at the joints between roof panels, and there has been a strong demand for improving the durability of roofs. Therefore, the brackets have been designed to firmly secure the roof panels together with the retaining clips. Such measures against negative pressure caused by strong winds are required not only for the above-mentioned fastening type folded plate roofs, but also for the interlocking type folded plate roofs that use interlocking cap materials. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2014-40720 A DISCLOSURE OF THEINVENTION [Problem to be solved by the invention]

[0007] As an example of a specific measure to prevent roof panels that make up a roof from being damaged by negative pressure caused by strong winds, there is a structure in which the roof panels are fixed to the roof bracket at a portion other than the connecting portion such as the fastening portion. Patent Document 1 is cited as a specific example. Patent Document 1 will be outlined below. The reference numerals used in Patent Document 1 will be used as they are.

[0008] Patent Document 1 discloses a roof material mounting part (3) and a leg part (1). A locking part (12) is formed in the vertical center of the side part of the folded plate roof material (10). The tight frame (T) is also equipped with a seam receiving part (6) that supports and fixes the fastening part between the folded plates. As seen in Patent Document 1, in recent years, a fastening type roof plate is formed with an engaged part in addition to the fastening part, and tight frames (roof supports) are often used that are configured so that the roof plate is fixed not only by the fastening connection part but also by the engaged part.

[0009] In Patent Document 1, the roofing material mounting part (3) is shaped like a cubic box with the opening facing downward, and one opposing side of the outer periphery of the roofing material mounting part (3) serves as the locking receiving part (5). As mentioned above, the weather environment has changed significantly in recent years, and the occurrence of typhoons has increased, and they are also becoming larger.

[0010] Therefore, the area of ​​the locking receiving portion (5) of the roof material mounting portion (3) in Patent Document 1 is small, and the range of locking with the locking portion (12) of the folded plate roof material (10) is also narrow, so the locking state is not necessarily perfect, and there is a possibility that the locking receiving portion (5) and the locking portion (12) will come off due to strong winds. Furthermore, Patent Document 1 discloses that in an embodiment in which the roof material mounting portion (3) and the leg portion (2) are separate members, they are joined by bolting. And, as a means of joining such metal parts together, the above-mentioned bolting and welding are generally used.

[0011] However, depending on the structure, bolted or welded joints may not provide sufficient joints, and bolts or welds may not be able to withstand the large negative pressure loads caused by typhoons, etc., as described above, and it is quite possible that the roof material attachment part (3) may come off the leg (2) together with the roof plate. In addition, welding joints may cause deformation of the roof material attachment part (3) from the leg (2) due to high temperatures during the work, so the welding area must be minimized. However, minimizing the welding area results in a contradictory situation in which sufficient joining strength cannot be obtained. Therefore, the object of the present invention is to provide a roof support and a folded plate roof that are extremely unlikely to come off the support due to strong winds and have excellent durability. [Means for solving the problem]

[0012] Therefore, the inventors have conducted intensive research to solve the above problems, and as a result, have discovered the invention of claim 1, which is an fitting attachment member comprising a base plate portion having a rectangular shape with fitting ends at both ends in the width direction, and a rectangular bulge portion formed on the base plate portion with an opening at the bottom and a retaining clip attachment hole, and a receiving body having a flat surface with a joining hole and a receiving top portion with an internal thread member welded to the underside of the joining hole, the receiving top portion being capable of being housed within the bulge portion, and the bulge portion of the fitting attachment member having a front end on one side of the bulge step rising surface portion, The above problem was solved by providing a roof support device characterized in that a bulging low top having a hole for attaching the retaining clip is formed on one side and a bulging high top is formed on the other side, and the support top of the support body has a low top having the connection hole and the internal screw member on one side of the support step rising surface and a high top on the other side, the low top is accommodated in the bulging low top and the high top is accommodated in the bulging high top, and the welding and fixing position is the contact surface between the bulging high top and the high top.

[0013] The above problem was solved by the invention of claim 2, which is a roof support as described in claim 1, characterized in that the welding between the contact surfaces of the flat surface of the support top and the underside of the bulge portion is performed by spot welding.

[0014] The invention of claim 3 is a fitting attachment member including a base plate portion having a rectangular shape with fitting ends at both ends in the width direction, a rectangular bulge portion formed on the base plate portion, having an opening downward and having a retaining clip attachment hole, and a receiving body having a flat surface with a joining hole and a receiving top portion with an internal thread member welded and fixed to the underside of the joining hole, the receiving top portion being capable of being accommodated within the bulge portion, the bulge portion of the fitting attachment member having a bulge lower top portion with the retaining clip attachment hole on one side of a bulge step rising surface portion and a bulge higher top portion on the other side, the receiving top portion of the receiving body having the joining hole and the internal thread member on one side of the receiving step rising surface portion. The above problem was solved by providing a folded plate roof, characterized in that a low-level receiving top is formed on one side and a high-level receiving top is formed on the other side, the bulging low-level receiving top is accommodated in the low-level receiving top, the bulging high-level receiving top is accommodated in the high-level receiving top, and the welding fixing position is a contact surface between the bulging high-level receiving top and the high-level receiving top, and a folded plate roof panel having rising portions formed on both sides in the width direction of the main plate, a connecting top is formed at the upper end of one of the rising portions in the width direction, and a fitted bent portion is formed at the middle point in the height direction of both the rising portions, and the fitted bent portion of the folded plate roof panel adjacent to the roof support is fitted into the fitting mounting member.

[0015] The above problem was solved by the invention of claim 4, which is a folded plate roof as described in claim 3, characterized in that the folded plate roof panel has a rising portion formed on both sides of the main panel in the width direction, a lower run portion is formed at the upper end of one rising portion in the width direction and an upper run portion is formed at the upper end of the other rising portion, and the lower run portion and the upper run portion of adjacent folded plate roof panels in the width direction are fastened via a fastening clip. Effect of the Invention

[0018] The invention of claim 1 comprises an interlocking mounting member having a rectangular base plate portion with interlocking ends at both widthwise ends, and a rectangular bulge portion formed on the base plate portion with an opening downward and in which a hole for attaching a retaining clip is formed, and a receiving body having a flat surface with a joining hole and a receiving top portion with an internal thread member welded and fixed to the underside of the joining hole, the receiving top portion being capable of being accommodated within the bulge portion, and the contact surfaces between the flat surface of the receiving top portion and the underside of the bulge portion are welded to each other.

[0019] With the above configuration, the top of the receiving body can be accommodated in the bulge of the fitting attachment member, the contact surfaces of the fitting attachment member and the receiving body are welded together, and the connection hole formed in the receiving top and the internal thread member welded and fixed to the bottom side of the receiving top and the connection hole location are configured so that parts necessary for roof construction such as retaining clips are bolted via the internal thread member during construction of a folded plate roof. As a result, the internal thread member is welded and fixed to the bottom side of the receiving top, the retaining clip is bolted, and the bulge of the fitting attachment member and the top of the receiving body are fixed at the welded fixing portion, so that the roof receiving device of the present invention can have an extremely strong structure.

[0020] Furthermore, the receiving body is provided with a fitting attachment member and a receiving body, and the fitting attachment member has a base plate-shaped portion and a bulge portion. The base plate-shaped portion is rectangular, and both ends in the X direction, i.e., the longitudinal direction, are fitting ends. In other words, by making both ends in the X direction of the rectangular base plate-shaped portion into fitting ends, the fitting ends that fit into the fitting bent portion of the folded roof panel are linear, and a large and effective fitting range can be secured.

[0021] The bulging portion is structured to bulge upward from the base plate portion as a base, and therefore the bulging portion has a generally shell-like structure or a generally monocoque structure. Therefore, the base plate portion and the bulging portion can mutually reinforce each other, and the fitting attachment member can have excellent mechanical strength.

[0022] Claim 1In the invention, the bulging portion of the fitting mounting member has a bulging low-level top portion having a hole for attaching the retaining clip on one side of the bulging step rising surface portion and a bulging high-level top portion on the other side, and the receiving top portion of the receiving body has a low-level top portion having the joining hole and the internal screw member on one side of the receiving step rising surface portion and a high-level top portion on the other side, the bulging low-level top portion is accommodated in the bulging high-level top portion and the high-level top portion is accommodated in the bulging low-level top portion, and at least one of the surfaces of the bulging low-level top portion and the low-level top portion, and the bulging high-level top portion and the high-level top portion are welded and fixed to each other, making it possible to create a roof receiving device that is suitable for constructing a fastening type folded plate roof.

[0023] Specifically, a low peak is formed on one side of the step rising surface and a high peak is formed on the other side, which is particularly suitable for construction of folded-plate type roofs and walls using fastening type folded-plate roof panels. In other words, a low peak and a high peak are provided on the bulging portion, and by installing a retaining clip for attaching the folded-plate roof panel at the low peak, the fastening connection between the fastening type folded-plate roof panels can be arranged in a stable state.

[0024] Furthermore, claim 1 In the invention, the position of the welded fastening is configured as the contact surface between the bulging high top and the receiving high top, and the welded fastening area at the bulging high top and the fastening area by the internal thread member and bolt are located at positions separated by a predetermined distance by the welded fastening area at the bulging high top and the internal thread member and bolt used to attach the fastening clip at the bulging low top, and the two fastening areas make it possible to make an even stronger roof receiving fixture.

[0026] Claim 2In the invention, the welding of the contact surfaces between the flat surface of the receiving top and the underside of the bulging portion is performed by spot welding, thereby minimizing the thermal distortion caused by welding between the fitting mounting member and the receiving body. This spot welding, the joint hole formed in the receiving top, and the internal thread member welded and fixed to the underside of the receiving top and to the joint hole location work synergistically with the configuration in which parts necessary for roof construction such as retaining clips are bolted via the internal thread member during the construction of the folded plate roof, making it possible to create a strong roof receiving device.

[0027] Claim 3 In the invention, by using extremely strong roof supports to create a folded plate roof, the roof constructed with folded plate roof panels is supported and fixed extremely firmly, and the folded plate roof panels are supported so as not to be blown away, especially even under the negative pressure of strong winds caused by typhoons, making it possible to create a folded plate roof with excellent durability. Claim 4 This invention makes it possible to construct an extremely strong fastening type corrugated plate roof. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0029] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The present invention is a roof support A constituting a folded plate roof, and a folded plate roof constructed by the roof support A. In addition, the folded plate roof constructed in a steeply inclined, approximately wall-like shape by the folded plate roof plate constituting the folded plate roof in the present invention is also included in the roof in the present invention.

[0030] First, in the present invention, the terms X-direction and Y-direction are used to indicate directions. The direction in which the multiple folded roof panels 8, 8, ... installed by the roof support A of the present invention are arranged side by side is the X-direction (see FIG. 4(B)), and the direction that is the longitudinal direction of each folded roof panel 8 is the Y-direction. Therefore, the longitudinal direction of the structural material 9 to which the roof support A of the present invention is attached is the X-direction (see FIG. 4). The Y-direction and the X-direction are described in the figure.

[0031] There are a first embodiment and a second embodiment of the roof support A in the present invention, both of which are composed of a metallic fitting attachment member A1 and a metallic support body A2. The fitting attachment member A1 is composed of a base plate portion 1 and a bulge portion 2 (see FIG. 1). The base plate portion 1 is formed in the shape of a rectangular plate with the X direction as the longitudinal direction. The plate thickness dimension of the base plate portion 1 is preferably about 2 mm to about 2.5 mm.

[0032] In the first embodiment of the roof support A of the present invention, the bulging portion 2 has an opening 2k on the lower side, and is a part that is a convex bulge when viewed from above the base plate portion 1 and a concave recess when viewed from below, and has a structure in which all four sides and the upper side are closed with the base plate portion 1 as a base (see Figs. 1 and 2). Specifically, it is shaped like a roughly square container made by splitting a capsule in half. The bulging portion 2 is roughly rectangular when viewed from above, and its four corners are rounded, that is, formed in an arc shape (see Figs. 3(B) and (E)).

[0033] The bulge 2 is formed to have the maximum area possible so as to fit inside the base plate part 1 (see Figs. 3(B) and (E)). In other words, the planar shape of the bulge 2 occupies a large proportion of the planar shape of the base plate part 1. The four corners of the bulge 2 are arc-shaped, so that the four corners of the base plate part 1 remain as flat areas. Furthermore, a small area that is approximately flat remains near the long sides of the base plate part 1 (see Figs. 1(C), 2(A), 3(B), (E), etc.).

[0034] The bulging portion 2 has a bulging step rising surface 21 at the middle in the X direction (see Figs. 1(B), (C), 2, 3, etc.). The bulging step rising surface 21 is a surface that is perpendicular to the X direction or the longitudinal direction of the bulging portion 2 and is substantially vertical. The portion on one side in the X direction of the bulging step rising surface 21 is a bulging low-level apex 22, and the portion on the other side in the X direction is a bulging high-level apex 23. The bulging low-level apex 22 is located lower than the bulging high-level apex 23 (see Figs. 1(B), (C), 2, 3, etc.). The bulging low-level apex 22 is the portion to which a clamping clip 84, which will be described later, is attached (see Fig. 4).

[0035] Both side surfaces of the bulging portion 2 in the X direction (longitudinal direction), that is, the outward facing side surfaces of the bulging low-level apex 22 and the bulging high-level apex 23, are formed as inclined surfaces that incline outward from above to below. The inclined surface continuing to the bulging low-level apex 22 side is called the low-level inclined surface 24, and the inclined surface continuing to the bulging high-level apex 23 side is called the high-level inclined surface 25 (see Figs. 1(B), 2(B), 3(A), and (D)). The corner 22t between the bulging low-level apex 22 and the low-level inclined surface 24 has an arc-shaped roundness. Similarly, the corner 23t between the bulging high-level apex 23 and the high-level inclined surface 25 also has an arc-shaped roundness (see Figs. 1(B), 2(B), 3(A), and (D)).

[0036] The positions of both ends of the longitudinal direction, i.e., the X-direction, of the base plate-shaped part 1 are fitting ends 11, 11 (see Figs. 1(B), 2(B), 3(A), and (D)). The fitting ends 11, 11 are straight edges at both opposing short sides of the rectangular base plate-shaped part 1. The fitting ends 11, 11 fit into the fitting bent parts 82a, 82a of the folded roof panel 8 described later, and serve to fix the folded roof panel 8 to the roof support (see Fig. 4). In other words, the fitting end 11 of the base plate-shaped part 1 can abut the fitting bent part 82a of the folded roof panel 8 in its entirety (see Fig. 4(C)). In addition, the fitting end 11 is in the same position as the lower ends of the lower inclined surface 24 and the higher inclined surface 25 of the bulging part 2.

[0037] Both fitting ends 11, 11 are formed with bent pieces 11a folded back toward the underside of the base plate-shaped part 1 (see Figs. 1(B), 2(B), 3(A), and (D)). Both bent pieces 11a are bent so as to be roughly inverted "V" shaped or horizontal. By forming both bent pieces 11a at both fitting ends 11, 11 of the base plate-shaped part 1, the mechanical strength of both fitting ends 11, 11 can be improved and the abutment state with the fitted bent part 82a of the folded roof panel 8 can be made more reliable.

[0038] Furthermore, when the fitted bent portion 82a of the folded roof panel 8 is fitted into the fitting end portion 11 of the fitting attachment member A1, it is possible to prevent damage to the inner surface side of the folded roof panel 8. A retaining clip attachment hole 28 is formed in the bulging lower top portion 22 of the bulging portion 2. The retaining clip attachment hole 28 is a hole through which a connecting bolt 61 passes for fixing a fastening retaining clip 84 or a fitting retaining clip 85 described later onto the fitting attachment member A1.

[0039] In a modified example of the first embodiment of the roof support A, although not shown in the figures, the area occupied by the bulging portion 2 with respect to the base plate portion 1 of the fitting mounting member A1 is reduced. In this modified example, the flat portion of the base plate portion 1 appears more. In other words, the base plate portion 1 has a larger area where the bulging portion 2 is not formed than in the first embodiment, and flat portions exist not only on both sides of the base plate portion 1 in the X direction, but also on both sides in the Y direction.

[0040] In addition, as a second modification of the first embodiment of the roof support A, although not shown in particular, the lower inclined surface 24 and the higher inclined surface 25 of the bulging portion 2 of the fitting mounting member A1 may be made substantially vertical. This allows the fitting mounting member A1 to further narrow the molding range of the bulging portion 2 and to enlarge the flat portion of the base plate-shaped portion 1. As in these modifications of the first embodiment, by reducing the forming area of ​​the bulging portion 2 relative to the base plate-shaped portion 1, the shape of the fitting end portions 11, 11 of the base plate-shaped portion 1 protrudes further and the angle of the bent piece 11a portion at the fitting end portion 11 becomes even more acute, making it easier to bite into the fitted bent portion 82a of the folded plate roof panel, and the fixed state of the folded plate roof panel 8 to the roof support can be made even stronger.

[0041] As described above, in the fitting attachment member A1 of the first embodiment and the modified example of the first embodiment, the bulging portion 2 is formed by bulging out of the base plate portion 1, so that the bulging portion 2 has a shape like a container formed by splitting a capsule in half. Therefore, the bulging portion 2 has a substantially shell-like structure or a substantially monocoque structure, and the base plate portion 1 and the bulging portion 2 can mutually reinforce each other, so that the fitting attachment member A1 can be synergistically made to have excellent mechanical strength.

[0042] Next, the receiving body A2 in the first embodiment is composed of a receiving top 51 and legs 52, 52 (see Fig. 1, Fig. 2(A), (B), Fig. 3, Fig. 4, etc.). The receiving top 51 has a receiving step rising surface 510, a receiving low-level top 511, and a receiving high-level top 512 (see Fig. 1, Fig. 2(A), (B), Fig. 3, Fig. 4, etc.). The receiving step rising surface 510 is a substantially vertical step boundary portion in the receiving top 51. With the receiving step rising surface 510 as a boundary, the receiving low-level top 511 is formed on one side of the receiving top 51 in the width direction (X direction) and the receiving high-level top 512 is formed on the other side (see Fig. 2(A) and (B)).

[0043] At the location of the connection hole 513, an internally threaded member 62 is fixed by welding to the underside of the receiving lower top portion 511 (see Figs. 1(B), 2(B), 3(A), (D), etc.). The internally threaded member 62 is a member in which an internal thread 62a is formed on the inner circumference of a through hole, and specifically, a nut is preferably used. Although not particularly shown, the internally threaded member 62 may be a member in which the internal thread 62a is formed on a metal material such as a rectangular parallelepiped or a flattened rectangular parallelepiped.

[0044] The legs 52, 52 are formed so as to incline downward and outward from both ends in the width direction (X direction) of the receiving top 51. The fitting attachment member A1 is disposed on the receiving body A2 such that the bulging low top 22 of the fitting attachment member A1 corresponds to the receiving low top 511 of the receiving body A2, and the bulging high top 23 of the fitting attachment member A1 corresponds to the receiving high top 512 of the receiving body A2 (see Figs. 1, 2, 3(A), (D), 4, etc.).

[0045] The receiving top portion 51 can be accommodated in the bulging portion 2, and the contact surfaces of the flat surface of the receiving top portion 51 and the lower surface of the bulging portion 2 are welded together (see FIG. 3). More specifically, the receiving top portion 51 of the receiving body A2 is inserted from the opening 2k side below the bulging portion 2 (see FIG. 2(B)). The receiving low-level top portion 511 of the receiving body A2 is accommodated in the bulging low-level top portion 22 of the bulging portion 2 of the fitting attachment member A1, and the receiving high-level top portion 512 is accommodated in the bulging high-level top portion 23 (see FIG. 3(C)). At least one of the surfaces of the bulging low-level top portion 22 and the receiving low-level top portion 511, and the bulging high-level top portion 23 and the receiving high-level top portion 512 are welded together (see FIGS. 1(B), (C), 3, 4(A), (C), etc.). This welded and fixed portion is referred to as a welded portion Aw.

[0046] The specific position of the welded portion Aw is preferably a portion where the bulging high top 23 of the fitting attachment member A1 and the receiving high top 512 of the receiving body A2 come into contact with each other (see Figs. 1(B), (C), 3(A), (B), (C), etc.). The welded portion Aw is provided at an appropriate position on the flat contact surfaces of both the fitting attachment member A1 and the receiving body A2. In the present invention, the welded portion Aw where the fitting attachment member A1 and the receiving body A2 are welded is preferably spot welded.

[0047] Specifically, the contact surfaces between the bulging high apex 23 and the receiving high apex 512 are provided at two points in the front-to-rear direction (Y direction) (see Figs. 1(C), 3(B), and (C)). Alternatively, seam welding may be performed to connect the two points in the front-to-rear direction. By spot welding or seam welding the welded fixing portion Aw, thermal deformation of the fitting attachment member A1 and the receiving body A2 due to welding during manufacturing can be substantially prevented.

[0048] The spot-welded or seam-welded welded fastening portion Aw is preferably provided on the contact surfaces of the bulging high top 23 of the fitting attachment member A1 and the receiving high top 512 of the receiving body A2. The bulging low top 22 of the fitting attachment member A1 and the receiving low top 511 of the receiving body A2 become the retaining clip installation surface and support portion, and the bulging high top 23 and the receiving high top 512 are provided with the welded fastening portion Aw by spot welding or seam welding, and the fastening retaining clip 84, the bulging low top 22 and the receiving low top 511 are fixed with the connecting bolt 61 and the internal thread member 62, so that the welded fastening portion Aw is communicated with, and the fitting attachment member A1 and the receiving body A2 are firmly joined by the mutual fastening force, making it possible to make an extremely strong roof support.

[0049] Also, a spot welded or seam welded welded portion Aw may be provided on the contact surfaces of the bulging lower top portion 22 and the receiving lower top portion 511 of the fitting attachment member A1 (see Figs. 3(D) and (E)). In this case, the position of the spot weld or seam weld is preferably immediately adjacent to the bulging step rising surface portion 21 of the fitting attachment member A1.

[0050] The folded-plate roof panel 8 corresponding to the roof support A in the first embodiment is used to construct a sash-fastening type folded-plate roof B1. The folded-plate roof panel 8 has inclined rising portions 82, 82 formed on both sides of the width direction (X direction) of the main plate 81, and connecting tops 83, 83 formed at the upper ends of the rising portions 82, 82.

[0051] A lower run portion 83a is formed at the connecting apex 83 on one side in the width direction of the folded roof panel 8, and an upper run portion 83b is formed at the connecting apex 83 on the other side. The lower run portion 83a and the upper run portion 83b are formed in a round run shape with an arc-shaped portion in their cross-sectional shape (see FIG. 4). In addition, although not specifically shown, there are also angular run types that are approximately square in shape and vertical run types that are approximately inverted L-shaped.

[0052] Next, a fitted bent portion 82a is formed on each of the rising portions 82. The fitted bent portion 82a is formed as a step portion in the middle of the height direction of each of the rising portions 82, and is a portion of the rising portion 82 formed so that the upper side of the step portion protrudes outward more than the lower side (see FIGS. 4(B) and (C)).

[0053] The engaging bent portion 82a engages with the engaging end portion 11 of the engaging mounting member A1, and together with the fastening points formed by the lower running portion 83a and the upper running portion 83b of adjacent folded roof panels 8, 8, serves to fix the folded roof panel 8 to structural materials 9 such as beams, purlins, and furring strips by the roof support A of the present invention (see Figure 4).

[0054] Next, the process of constructing a saddle-fastening type folded-plate roof B1 using the roof support A of the present invention, a folded-plate roof panel 8, and a structural material 9 will be described. First, a plurality of the roof supports A, A, ... of the present invention are placed on a structural material 9 such as a purlin. At this time, the interval between each adjacent roof support is set to a range in which the fitting ends 11, 11 of the adjacent fitting mounting members A1, A1 can be properly fitted to the fitting bent parts 82a, 82a formed on both sides of the width direction of the folded-plate roof panel 8 (see FIG. 4(A)).

[0055] Then, the folded roof panel 8 is placed between the opposing fitting attachment members A1, A1 of the adjacent roof supports A, and the folded roof panel 8 is pushed in so that both fitting bent portions 82a, 82a are fitted into the fitting protrusions 11, 11 of the fitting attachment members A1, A1 of the adjacent roof supports (see Fig. 4(C)). Also, the fastening clip 84 is fixed to the bulging lower top portion 22 of the fitting attachment member A1 of the roof support by the connecting bolt 61 of the connector 6 and the internal thread member 62, and the lower running portion 83a and the upper running portion 83b of the adjacent folded roof panels 8, 8 are fastened to each other to construct the roof (see Fig. 4).

[0056] The fastening clip 84 has a washer portion 84a and a tongue piece 84b, and the washer portion 84a is placed on the bulging lower top portion 22 of the fitting mounting member A1, and the washer portion 84a is fixed by the connecting bolt 61 of the connector 6 and the internal thread member 62. A through hole is formed in the washer portion 84a through which the connecting bolt 61 passes. In addition, the lower running portion 83a and the upper running portion 83b of the adjacent folded roof panels 8, 8 are fastened so as to sandwich the tongue piece 84b of the fastening clip 84 (see Figures 4(B) and (C)).

[0057] In this way, the folded roof panel 8 is fixedly supported to the bulging low top 22 of the fitting mounting member A1 of the roof bracket A of the present invention via the clamping clip 84, and the fitted bent portions 82a, 82a of the folded roof panel 8 are fixed to the fitting portions by both fitting ends 11, 11 of the roof bracket A.

[0058] In other words, the roof support A of the present invention can fix the folded roof panel 8 at multiple points, the fastening clip 84 attached to the bulging lower top 22 of the fitting mounting member A1, and the fitting ends 11, 11. As a result, the roof support A of the present invention can very firmly support and fix the roof constructed with the folded roof panels 8, 8, ..., and can demonstrate excellent durability, especially against negative pressure caused by strong winds.

[0059] Next, a second embodiment of the roof support A of the present invention will be described mainly with reference to Figs. 5 and 6. The second embodiment of the roof support A corresponds to an interlocking type folded plate roof using an interlocking cap material 86 and an interlocking retaining clip 85 (see Figs. 5 and 6). The interlocking mounting member A1 in the second embodiment has a configuration substantially similar to that of the interlocking mounting member A1 in the first embodiment, and is composed of a base plate portion 1 and a bulge portion 2. The base plate portion 1 is formed in a rectangular plate shape with the X direction as the longitudinal direction. The plate thickness dimension of the base plate portion 1 is preferably about 2 mm to about 2.5 mm.

[0060] The bulging portion 2 is a convex bulge that is approximately trapezoidal when viewed from above the base plate portion 1, and is a concave recess when viewed from below, and has a structure in which all four sides and the top are closed with the base plate portion 1 as a base (see Figs. 5(A) and (B)). An opening 2k exists on the lower side of the bulging portion 2. Specifically, it is shaped like a roughly square container made by splitting a capsule in half. The bulging portion 2 is approximately rectangular when viewed from above, and its four corners are rounded, that is, formed in an arc shape (see Fig. 5(C)).

[0061] The bulge 2 is formed to have the maximum area possible so as to fit within the base plate part 1 (see Figs. 5(B), 6(A), and (C)). In other words, the planar shape of the bulge 2 occupies a large proportion of the planar shape of the base plate part 1. The four corners of the bulge 2 are arc-shaped, so that the four corners of the base plate part 1 remain as flat parts. Furthermore, a small area that is approximately flat remains near the long sides of the base plate part 1.

[0062] The bulging portion 2 has a flat top portion 26 that is a substantially single flat surface, and has inclined end faces 27, 27 formed at both ends in the X direction. Corners 26t, 26t between the flat top portion 26 and the inclined end faces 27, 27 are rounded in an arc shape (see Figs. 5(B), (C), 6(A), (C)).

[0063] The base plate portion 1 is the same as the base plate portion 1 of the fitting attachment member A1 in the first embodiment, and the positions of both ends in the longitudinal direction, i.e., the X direction, are fitting ends 11, 11. The fitting ends 11, 11 are formed with bent pieces 11a, 11a that are folded back toward the underside of the base plate portion 1. A retaining clip attachment hole 28 is formed in the flat top portion 26 of the bulge portion 2 (see Figs. 5 and 6(A)). The retaining clip attachment hole 28 is a hole through which a connecting bolt 61 passes to fix the fitting retaining clip 85 onto the fitting attachment member A1.

[0064] Next, the receiving body A2 of the second embodiment of the roof receiving tool A of the present invention is composed of a flat receiving top portion 53 and legs 52, 52 (see Figs. 5 and 6(A)). The flat receiving top portion 53 is formed flat. The flat receiving top portion 53 has a connection hole 513 formed at the center position in both the width direction (X direction) and the front-rear direction (Y direction).

[0065] An internally threaded member 62 is fixed by welding to the underside of the flat receiving top portion 53 at the location of the joining hole 513. The internally threaded member 62 is a member having an internal thread 62a formed on the inner circumference of a through hole, and specifically, a nut is preferably used. Although not shown, the internally threaded member 62 may also be a member having an internal thread 62a formed on a metal material such as a rectangular parallelepiped or flattened rectangular parallelepiped.

[0066] The connecting bolt 61 can pass through the joining hole 513, and the fitting retaining clip 85 connects the fitting mounting member A1 to the receiving body A2 via the internal thread member 62. The tip of the connecting bolt 61 is inserted into the connecting fixing hole 26a formed in the flat top 26 of the fitting mounting member A. The legs 52, 52 are formed so as to incline downward and outward from both ends of the receiving top 51 in the width direction (X direction).

[0067] Then, the flat top portion 53 of the receiving body A2 is inserted through the opening 2k of the bulging portion 2 of the fitting attachment member A1, and the flat top portion 26 of the fitting attachment member A1 and the flat top portion 53 of the receiving body A2 are welded and fixed. This welded and fixed portion is called the welded fixed portion Aw, as in the first embodiment. The specific position of the weld at the welded fixed portion Aw is the contact surface between the flat top portion 53 of the fitting attachment member A1 and the flat top portion 53 of the receiving body A2, and welding is performed at this portion.

[0068] Specifically, the flat top portion 26 of the fitting attachment member A1 and the flat top portion 53 of the receiving body A2 are welded together, and the welding position is in the width direction (X direction) of the flat top surface portion 26, with the retaining clip attachment hole 28 as the center, and welded and fixed portions Aw are provided on both sides in the X direction (see FIG. 5). Also, both of the welded and fixed portions Aw are preferably spot welded, but may be seam welded.

[0069] Next, we will explain the fitting type folded plate roof B2 corresponding to the fitting attachment member A1 of the second embodiment of the roof support A in the present invention. This fitting type folded plate roof B2 mainly comprises a folded plate roof panel 8, a fitting cap material 86, and a fitting retaining clip 85. In this fitting type folded plate roof panel 8, inclined rising parts 82, 82 are formed on both sides of the width direction of the main panel 81, and fitting connection top parts 83c, 83c that fit with the fitting cap material 86 are formed at the upper ends of the parts (see Figures 6(B) and (C)).

[0070] The fitting retaining clip 85 has tongue pieces 85b, 85b formed on both sides in the width direction (X direction) of a substantially rectangular parallelepiped housing part 85a (see FIG. 6(A)). A through hole through which a connecting bolt 61 passes is formed in the bottom part of the housing part 85a. The fitting retaining clip 85 is placed on the top part 21 of the fitting mounting member A, and the receiving top part 51 of the receiving main body A2 and the fitting mounting member A1 are fixed with the connecting bolt 61 and the internal thread member 62.

[0071] Then, adjacent folded plate roof plates 8, 8 are placed on both sides of the fitting retainer 85, and the fitting connection tops 83c, 83c are wrapped and fixed by the tongue pieces 85b, 85b formed on both sides of the width direction (X direction) of the housing part 85a of the fitting retainer 85, and the fitting cap material 86 is fitted onto both adjacent fitting connection tops 83c, 83c. This is repeated in sequence to construct a fitting type folded plate roof B2 using the fitting cap material 86. [Explanation of symbols]
