Description

[Technical Field]

[0001] The present invention relates to a support member for a structure used for a folded-plate roof or the like in various buildings. [Background technology]

[0002] In various buildings, folded plates formed by folding metal sheets into a corrugated shape, so-called folded plate roofs, are used as roof materials. Various equipment such as solar panels and relay boxes may be fixed on top of these folded plate roofs. Generally, the multiple folded plates that make up a folded plate roof are connected to each other via seams (caulkings) formed by plastically deforming the edges of the metal plates. When fixing various equipment on top of a folded plate roof, for example, as shown in Patent Documents 1 to 3, a support member equipped with clamps that clamp the seam from both sides is used. A frame is attached to the top of the support member fixed to the seam, and various equipment is attached to the frame. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2018-197442 [Patent Document 2] Registered Utility Model No. 3176991 [Patent Document 3] Japanese Patent Application Laid-Open No. 2000-336857 Summary of the Invention [Problem to be solved by the invention]

[0004] In the support member of Patent Document 1, the first and second clamping members that clamp the seam portion from both sides are fastened and fixed by horizontal bolts, and the frame (the member to be fixed) is supported by another bolt extending upward from the first clamping member. Therefore, when attaching the support member to the folded-plate roof, it is necessary to widen the gap between the lower ends of the first and second clamping members. At this time, there is a possibility that the first and second clamping members will disengage and separate. Therefore, the installation work of the support member is complicated.

[0005] In the support member of Patent Document 2, the first clamping member (left clamping plate) and the second clamping member (right clamping plate) are connected by vertical bolts, so they cannot be separated. However, because the first clamping member and the second clamping member are fastened laterally only by vertical bolts, there is a problem in that the fastening force is insufficient.

[0006] Furthermore, in the support member of Patent Document 3, the first clamping member (clamping piece) and the second clamping member (clamping piece) are connected by a horizontal bolt and also by a vertical bolt, so the two do not separate. Furthermore, because the first clamping member and the second clamping member are fastened together by a horizontal bolt, a certain degree of fastening force can be ensured. However, because the first clamping member and the second clamping member are fastened together by only one horizontal bolt, the strength of the member may be insufficient when installing heavy equipment such as solar panels on a folded-plate roof, for example.

[0007] Therefore, an object of the present invention is to increase the strength of a support member attached to a structure such as a folded plate roof. [Means for solving the problem]

[0008] In order to solve the above problems, the present invention provides a support member for a structure used to fix a device to a structure having a protruding portion, the support member comprising a first clamping member and a second clamping member that clamp the protruding portion from both sides along one direction, and a fixing means for fixing the device, the first clamping member and the second clamping member being rotatable around a first axis that extends in another direction intersecting the one direction, and the first clamping member and the second clamping member being fastened in a direction in which they approach each other by a second axis that extends in the one direction (Configuration 1).

[0009] In the configuration 1, a configuration can be adopted in which the first clamping member and the second clamping member can be fastened by the first shaft so as not to move at any rotational position (configuration 2).

[0010] In configuration 1 or 2, the first axis can be inserted into holes provided in the first clamping member and the second clamping member, and at least one of the holes can be an elongated hole whose longitudinal direction faces in the one direction (configuration 3).

[0013] In the configuration 4 or 5, the reinforcing member may be configured to be movable in the other direction relative to the first clamping member and the second clamping member (configuration 6).

[0014] In addition, in configuration 4 or 5, a configuration can be adopted in which the reinforcing member is movable in the other direction relative to the first clamping member and the second clamping member, and an elastic member that urges the reinforcing member along the other direction is arranged between the reinforcing member and the first clamping member or the second clamping member (configuration 7).

[0015] Furthermore, in the configuration 4 or 5, the reinforcing member may be configured to be movable in the one direction and the other direction relative to the first clamping member and the second clamping member (configuration 8).

[0016] In any one of configurations 1 to 8, the first clamping member can include a first base having a first through hole through which the second shaft is inserted, and a first pressing piece that rises in one direction from the first base and faces the side of the protrusion, and the second clamping member can include a second base having a first through hole through which the second shaft is inserted, and a second pressing piece that rises in one direction from the second base and faces the side of the protrusion (configuration 9).

[0017] In addition, in order to solve the above-mentioned problems, the present invention provides a support member used to fix a device to a structure, which includes a holding member made of an integral member fixed to the structure, a first axis inserted into the holding member, a reinforcing member through which the first axis is inserted, and fixing means provided on the reinforcing member for fixing the device, and the reinforcing member can be a support member for a structure that is movable in the axial direction of the first axis relative to the holding member (Configuration 10).

[0018] In the configuration 10, a configuration can be adopted in which an elastic member is disposed between the reinforcing member and the holding member to bias the reinforcing member along the axial direction of the first shaft (configuration 11).

[0019] In addition, in Configuration 10 or 11, the holding member may have a bottom portion, and the bottom portion may have a hole through which a fixing means rising from the structure is inserted (Configuration 12).

[0020] In addition, in Configuration 10 or 11, the holding member may have a bottom portion, and the bottom portion may have a slit through which a protrusion provided on the structure is inserted (Configuration 13). [Effects of the Invention]

[0023] An embodiment of the present invention will be described with reference to the drawings. This embodiment relates to a support member 10 for a structure (hereinafter simply referred to as the support member 10) used to secure various equipment (various devices) such as solar panels to a folded-plate roof (structure) 1 used as a roofing or ceiling material in various buildings such as warehouses and factories, and a support structure for various equipment to a structure using the support member 10.

[0024] (First embodiment) The configuration of the support member 10 is shown in Figures 1 and 2, and Figure 3 shows the support member 10 attached to the folded-plate roof 1. Figures 4 to 6 show the support member 10 in detail.

[0025] As shown in FIG. 3, the folded-plate roof 1 is a so-called folded-plate roof, constructed by bending a metal plate into a corrugated shape. Its shape consists of a top section 3 with a horizontal plate surface and a bottom section 5 with a similarly horizontal plate surface, alternately connected by inclined sections 4, resulting in a large number of parallel, corrugated sections in cross section. The connections between the top section 3 and the inclined sections 4, and between the bottom section 5 and the inclined sections 4, are the folding points of the metal plate, resulting in an overall structure with alternating peaks and valleys. As shown in FIG. 3, the folded-plate roofs 1 are connected in the width direction via protrusions 2 (hereinafter referred to as seam sections 2 in the embodiment) formed by crimping the edges of the metal plate by plastic deformation. The seam sections 2 are ridges that protrude upward longitudinally along the entire length of the folded-plate roof 1. Furthermore, the folded-plate roofs 1 are connected in the longitudinal direction by overlapping the peaks and valleys of adjacent folded-plate roofs 1 with bolts that pass through the overlapping portions and nuts that are screwed onto the bolts. A folded plate roof 1 is supported by beams (not shown) of a building or the like.

[0026] The width of the peak 3 and bottom 5, the difference in elevation between the peak 3 and bottom 5, the angle of inclination of the inclined portion 4, etc. are set arbitrarily according to the specifications of the folded-plate roof 1. Hereinafter, the parallel direction of the peaks and valleys will be referred to as the width direction (one direction) of the folded-plate roof 1, and the direction in which the peaks and valleys extend will be referred to as the longitudinal direction (other direction) of the folded-plate roof 1. Multiple folded-plate roofs 1 are used by being connected together in the width direction and longitudinal direction. The width and length of one folded-plate roof 1, and the number of repetitions of the peaks and valleys, are set appropriately according to the specifications.

[0027] 1 and 2, the support member 10 includes a first clamping member 20 and a second clamping member 30 that clamp the seam 2 of the folded-plate roof 1 from both sides along one direction. The support member 10 also includes a reinforcing member 40 having fixing means 70 for fixing various equipment to be placed on the folded-plate roof 1.

[0028] The first clamping member 20 and the second clamping member 30 are rotatable about a first shaft 50 extending in the longitudinal direction (the other direction) of the folded-plate roof 1. In addition, the first clamping member 20 and the second clamping member 30 can be fastened in a direction in which they approach each other by a second shaft 60 extending in the width direction (one direction) of the folded-plate roof 1.

[0029] The first clamping member 20 includes a first base portion 21 having a first through-hole 25 through which the second shaft 60 is inserted, and a first pressing piece 22 that rises from the first base portion 21 in one direction and faces the side surface of the seam portion 2. The first pressing pieces 22 are provided at both ends of the first base portion 21 in the other direction, and a pair of first pressing pieces 22, 22 protrude parallel to one direction. As a result, the first clamping member 20 is a member having a U-shaped cross section in a plan view. Each of the first pressing pieces 22, 22 includes a support portion 23 at its upper portion that has a second through-hole 24 through which the first shaft 50 is inserted, and a pressing portion 26 at its lower portion that faces the side surface of the seam portion 2. The tip edge of the pressing portion 26 (the edge facing the seam portion 2) is positioned slightly back from the edge of the support portion 23, creating a step between the support portion 23 and the pressing portion 26.

[0030] The second clamping member 30 includes a second base portion 31 having a first through hole 35 through which the second shaft 60 is inserted, and a second pressing piece 32 that rises from the second base portion 31 in one direction and faces the side surface of the seam portion 2. The second pressing pieces 32 are provided at both ends of the second base portion 31 in the other direction, and a pair of second pressing pieces 32, 32 protrude parallel to one direction. As a result, the second clamping member 30 is a member having a U-shaped cross section in a plan view. Each second pressing piece 32, 32 includes a support portion 33 at its upper portion that has a second through hole 34 through which the first shaft 50 is inserted, and a pressing portion 36 at its lower portion that faces the side surface of the seam portion 2. The tip edge of the pressing portion 36 (the edge facing the seam portion 2) is positioned slightly back from the edge of the support portion 33, creating a step between the support portion 33 and the pressing portion 36. In addition, a retaining portion 37 that protrudes toward the first clamping member 20 is provided below the pressing portion 36. The tip edge of the retaining portion 37 is located at a position that protrudes further toward the first clamping member 20 than the tip edge of the pressing portion 36.

[0031] The reinforcing member 40 includes a top surface 41 located above, a base facing portion 43 that rises downward from the top surface 41 and faces the first base portion 21 and the second base portion 31, and a pressing piece facing portion 42 that rises downward from the top surface 41 and faces the first pressing piece 22 and the second pressing piece 32. The base facing portions 43 are provided on both ends of the top surface 41 in one direction, with a pair of base facing portions 43, 43 protruding downward in parallel. The pressing piece facing portions 42 are provided on both ends of the top surface 41 in the other direction, with a pair of pressing piece facing portions 42, 42 protruding downward in parallel. As a result, the reinforcing member 40 is a member that forms a downwardly concave shape.

[0032] The first clamping member 20, the second clamping member 30 and the reinforcing member 40 are formed by bending a flat plate-like member by press working or the like.

[0033] In this embodiment, the fixing means 70 is provided on the reinforcing member 40. The fixing means 70 includes a bolt shaft 71 that passes through the top surface portion 40 in the vertical direction, and a nut 72 that is screwed onto the male thread of the bolt shaft 71 (see FIG. 3). The bolt shaft 71 is inserted into a hole in an angle member 74, and the nut 72 is tightened via a washer 73, thereby fixing the angle member 74 onto the folded-plate roof 1. Various pieces of equipment are fixed to the angle member 74.

[0034] The first clamping member 20 and the second clamping member 30 can be fastened in a direction in which they approach each other by a second shaft 60 that extends in the width direction (one direction) of the folded-plate roof 1. In this embodiment, the second shaft 60 is a bolt shaft 61, and by screwing a nut 62 onto the male threaded portion of the bolt shaft 61 via a washer 63 and fastening it, the first clamping member 20 and the second clamping member 30 are pressed in a direction in which they approach each other.

[0035] The first clamping member 20 and the second clamping member 30 are rotatable about the axis of a first shaft 50 extending in the longitudinal direction (the other direction) of the folded-plate roof 1. When the first clamping member 20 and the second clamping member 30 approach each other by the second shaft 60, they rotate about the axis of the first shaft 50. In addition, the first clamping member 20 and the second clamping member 30 can be fastened by the first shaft 50 so as not to move at any rotational position. The first shaft 50 in the embodiment is a bolt shaft 51, and by screwing a nut 52 onto the male threaded portion of the bolt shaft 51 via a washer 53 and fastening it, the contact surfaces of the first clamping member 20 and the second clamping member 30 come into close contact, and they are fixed in a state where they do not rotate.

[0036] 1, in the embodiment, the second pressing pieces 32, 32 of the second clamping member 30 are positioned more inward than the first pressing pieces 22, 22 of the first clamping member 20, but this arrangement can be changed as appropriate. For example, this may be reversed so that the second pressing pieces 32, 32 of the second clamping member 30 are positioned more outward than the first pressing pieces 22, 22 of the first clamping member 20.

[0037] Here, the first shaft 50 is inserted through holes 24, 34 provided in the first clamping member 20 and the second clamping member 30. The holes 24, 34 penetrate the first pressing pieces 22, 22 and the second pressing pieces 32, 32 in the plate thickness direction, respectively. At least one of the holes 24, 34 is preferably an elongated hole whose longitudinal direction faces the one direction. By making at least one of the holes 24, 34 an elongated hole, it becomes easier to widen the gap between the first clamping member 20 and the second clamping member 30 when they grip the seam portion 2. Here, only the hole 24 on the first clamping member 20 side may be an elongated hole, or only the hole 34 on the second clamping member 30 side may be an elongated hole, or both may be elongated holes as in this embodiment (see FIG. 2).

[0038] The reinforcing member 40 is disposed between the first clamping member 20 and the second clamping member 30. A first shaft 50 and a second shaft 60 are inserted through the reinforcing member 40. As described above, the fixing means 70 is provided on the reinforcing member 40. By providing the member that fastens the seam portion 2 of the folded-plate roof 1 and the member that supports various equipment as separate members, the strength of the support member 10 is further increased.

[0039] As shown in Figure 3, the shape of the seam portion 2 in this embodiment is a hollow box-shaped portion with a rectangular cross section, including a rising portion 2a, a top portion 2b, a vertical portion 2c, and a folded portion 2d, protruding upward from the top surface 3. With respect to the seam portion 2 having this box-shaped portion, the pressing portion 26 of the first pressing piece 22 provided on the first clamping member 20 faces one side surface of the rising portion 2a (the side surface on the left in the figure). The pressing portion 26 elastically presses the upper portion of the rising portion 2a while elastically deforming the seam portion 2. The symbol 2e in the figure denotes a core material held in the seam portion 2 to secure the folded-plate roof 1 to a beam material (not shown) of a building or the like.

[0040] Furthermore, the pressing portion 36 of the second pressing piece 32 provided on the second clamping member 30 faces the other side surface of the vertical portion 2c (the side surface on the right side in the figure). Furthermore, the retaining portion 37 below the pressing portion 36 faces the folded portion 2d. The retaining portion 37 elastically presses the vertical portion 2c and the folded portion 2d while accompanying the elastic deformation of the seam portion 2. Such elastic holding can be easily achieved by the tightening operation of the first shaft 50 and the second shaft 60.

[0041] Here, the tip edge of pressing portion 26 (the edge facing seam portion 2) presses against rising portion 2a of seam portion 2, and the tip edge of pressing portion 36 (the edge facing seam portion 2) faces against vertical portion 2c of seam portion 2, and retaining portion 37 presses against folded-back portion 2d at a position recessed from vertical portion 2c. This makes it possible to firmly hold seam portion 2, and also exhibits a retaining function that prevents support member 10 from falling off seam portion 2 even when external force such as wind acts on various pieces of equipment.

[0042] Second Embodiment A second embodiment of the present invention is shown in Figures 6 to 8. In this embodiment, a reinforcing member 40 is movable in one direction and the other direction relative to the first holding member 20 and the second holding member 30.

[0043] 5, in the first embodiment described above, the reinforcing member 40 faces the inner surface of the first pressing piece 22 of the first clamping member 20 or the second pressing piece 32 of the second clamping member 30 with no gap or a small gap therebetween, and is in a state where it hardly moves in the axial direction (one direction) of the first shaft 50. In addition, since the first shaft 50 is inserted through a hole 44 (which is not an elongated hole) formed in the reinforcing member 40, the reinforcing member 40 is in a state where it hardly moves in the axial direction of the second shaft 60 (the other direction).

[0044] In contrast, in the second embodiment shown in FIGS. 6 to 8, the reinforcing member 40 faces the inner surface of the first pressing piece 22 of the first clamping member 20 or the second pressing piece 32 of the second clamping member 30, with a certain amount of clearance between them. The hole 45 formed in the reinforcing member 40 is an elongated hole extending in another direction (see FIG. 6). This allows the reinforcing member 40 to move to some extent in the axial direction of the first shaft 50 (the other direction). Furthermore, the hole 44 formed in the reinforcing member 40 is also an elongated hole extending in one direction (see FIG. 6). This allows the reinforcing member 40 to move to some extent in the axial direction of the second shaft 60 (the one direction). The folded-plate roof 1 is a member with relatively large dimensional errors, and the various equipment placed on it also has large dimensional errors. Therefore, position adjustment by moving the reinforcing member 40 in this manner is very effective.

[0045] In each of the above-described embodiments, the first shaft 50 of the embodiment is a bolt shaft 51, and a nut 52 is screwed onto the male thread of the bolt shaft 51 via a washer 53 to be fastened, but the configuration of the first shaft 50 that fastens the first clamping member 20 and the second clamping member 30 is not limited to this embodiment. For example, a cam shaft with a cam at the base and a lever at the tip may be used, and the first clamping member 20 and the second clamping member 30 may be fastened using the pressing action of the cam caused by lever operation. The second shaft 60 is also similar to the first shaft 50. This also applies to each of the embodiments described below.

[0046] (Third and fourth embodiments) A third embodiment of the present invention is shown in Fig. 9, and a fourth embodiment is shown in Fig. 10. These embodiments use a rivet as the first shaft 50. In Fig. 9, a rivet is used as the first shaft 50 instead of the bolt shaft in the embodiment of Fig. 5. In the figure, the lower end of the first shaft 50 is the head of the rivet, and the upper end is the crimped portion of the rivet. Other configurations are the same as those of the first and second embodiments described above.

[0047] FIG. 10 shows an embodiment in which two rivets are used as the first shafts 50. At the top of the figure, the first pressing piece 22, the second pressing piece 32, and the pressing piece opposing portion 42 are pin-joined by one first shaft 50, and at the bottom of the figure, the first pressing piece 22, the second pressing piece 32, and the pressing piece opposing portion 42 are pin-joined by another first shaft 50. The crimping process is facilitated when the rivet has a hollowed-out shaft (see FIG. 9) in advance. The remaining configuration is the same as in the first and second embodiments. The first shaft 50 in the embodiment in which a bolt shaft is used (see FIG. 5) may be divided into two as shown in FIG. 10.

[0048] Fifth Embodiment A fifth embodiment of the present invention is shown in Figures 11 to 16. The following description will focus on the differences from the first to fourth embodiments.

[0049] In the fifth embodiment, a first shaft 50 is inserted through the first clamping member 20, the second clamping member 30, and the reinforcing member 40, and the first clamping member 20 and the second clamping member 30 are rotatable about the first shaft 50 extending in the other direction. In addition, a second shaft 60 extending in one direction is inserted through the first clamping member 20 and the second clamping member 30, and the first clamping member 20 and the second clamping member 30 can be fastened by the second shaft 60 in a direction in which they approach each other. However, the second shaft 60 is not inserted through the reinforcing member 40.

[0050] The first clamping member 20 and the second clamping member 30 are configured as members that are longer in the other direction than those in the first to fourth embodiments described above. Accordingly, the first shaft 50 is also configured as a member that is longer in the other direction than those in the first to fourth embodiments described above. For this reason, a plurality of second shafts 60 (two in this embodiment) are inserted through the first clamping member 20 and the second clamping member 30 in the other direction. In this way, the number of second shafts 60 can be increased or decreased as appropriate according to the lengths of the first clamping member 20 and the second clamping member 30 in the other direction.

[0051] The reinforcing member 40 is movable in the other direction relative to the first clamping member 20 and the second clamping member 30. Therefore, when the folded-plate roof 1 thermally expands in the other direction due to a temperature rise or the like, even if the first clamping member 20 and the second clamping member 30 fixed to the folded-plate roof 1 move in that direction, the reinforcing member 40 can remain in the position before the thermal expansion or in a position with a small amount of movement. This reduces the force applied to the folded-plate roof 1. Furthermore, when an external force acts on the device on the folded-plate roof 1 due to wind or the like, the reinforcing member 40 moves, thereby reducing the force applied to the folded-plate roof 1. For example, as shown by the arrows in Figure 16, thermal expansion causes the line indicated by symbol b on the folded-plate roof 1 to move to the line indicated by symbol a, but the reinforcing member 40 does not move to the position indicated by the dashed line and remains in the position indicated by the solid line.

[0052] At this time, the second shaft 60 does not interfere with the movement of the reinforcing member 40. Also, in Figures 11 to 16, the reinforcing member 40 is movable in the other direction but not in one direction, but it may be movable in both the other direction and one direction. In this case, the hole 44 formed in the reinforcing member 40 may also be an elongated hole extending in one direction (see Figure 6), and the gap (gap in one direction) between the base-facing portion 43 of the reinforcing member 40 and the first base 21 and second base 31 may be enlarged.

[0053] Additionally, an elastic member 54 that biases the reinforcing member 40 along the axial direction (the other direction) of the first shaft 50 is disposed between the reinforcing member 40 and the first pressing piece 22 of the first clamping member 20, i.e., between the reinforcing member 40 and the second pressing piece 32 of the second clamping member 30. The elastic members 54 are provided on both sides of the reinforcing member 40 in the other direction, sandwiching the reinforcing member 40 between them. This makes it easy to return the reinforcing member 40 to the neutral position (the position it was in before the thermal expansion of the folded-plate roof 1) in accordance with changes in the degree of thermal expansion.

[0054] The shapes of the first clamping member 20 and the second clamping member 30 are the same as those of the first and second embodiments, except that their lengths in other directions are longer than those of the first and second embodiments (see Figures 13 and 14).

[0055] (Sixth embodiment) A sixth embodiment of the present invention is shown in Figures 17 to 19. In this sixth embodiment, instead of the first clamping member 20 and the second clamping member 30, a holding member 80 made up of an integral member is employed.

[0056] The holding member 80 has base portions 82, 83 on both sides in one direction, each having a first through hole 85, 86 through which the second shaft 60 is inserted. The holding member 80 also has end surface portions 81, 81 on both sides in the other direction, which connect the end portions of the base portions 82, 83 on the other side. This makes the holding member 80 a frame-like member that is rectangular in plan view. The holding member 80 can be easily manufactured, for example, by deforming a plate-like member shown in FIG. 18 by press working or the like. The holding member 80 of this embodiment has a shape in which the base portions 82, 83 and the end surface portions 81, 81 rise from the four sides of the outer edge of a bottom portion 89 that is rectangular in plan view.

[0057] The first shaft 50 is inserted through second through holes 84 provided in the end surface portions 81 at both ends. The first through holes 85, 86 through which the second shaft 60 is inserted are elongated holes extending in the other direction, as shown in FIGS. 17 and 18 . Therefore, when the reinforcing member 40 moves along the axial direction (the other direction) of the first shaft 50, the second shaft 60 moves along the longitudinal direction of the first through holes 85, 86, thereby guiding the movement. Similar to the fifth embodiment, an elastic member 54 is disposed between the reinforcing member 40 and the holding member 80 to bias the reinforcing member 40 along the axial direction of the first shaft 50.

[0058] The retaining member 80 can be easily fixed to the folded-plate roof 1 by inserting a fixing means 90 rising from the folded-plate roof 1 into a hole 87 provided in the bottom 89. The fixing means 90 in the embodiment is composed of a bolt 91, a nut 92, and a washer 93, but rivets or various other fastening means may also be used as the fixing means 90.

[0059] Seventh Embodiment A seventh embodiment of the present invention is shown in Figure 20. In this seventh embodiment, a slit 88 is used as the fixing structure of the retaining member 80 to the folded-plate roof 1 instead of the hole 87 in the bottom 89 and the fixing means 90 in the sixth embodiment.

[0060] The slit 88 is formed over the entire length of the bottom portion 89 in the other direction, and both ends thereof are continuous with the notches formed in the end face portions 81, 81. The bottom portion 89 is divided into a first bottom portion 89a and a second bottom portion 89b by the slit 88. The notch has a shape and size corresponding to the cross-sectional shape of the protruding portion 2 of the folded-plate roof 1, and its configuration corresponds to the state after the first clamping member 20 and the second clamping member 30 in the first embodiment are fastened to each other (see FIG. 3).

[0061] The retaining member 80 is slid in the other direction from the other edge side of the folded-plate roof 1, and the retaining member 80 is moved to a predetermined position while the protruding portion 2 enters the slit 88 of the bottom portion 89 and the notch of the end surface portion 81. Since the protruding end side of the protruding portion 2 has a shape that bulges more than the base side, the protruding portion 2 enters into the notch and is prevented from coming off.

[0062] Thereafter, the second shaft 60 is inserted into the first through-hole 85. Since the first through-hole 85 is formed with a female thread, by screwing the second shaft 60 in and abutting its tip against the side surface of the protruding portion 2, the fixing of the holding member 80 to the folded-plate roof 1 becomes stronger.

[0063] In each of the above embodiments, the first clamping member 20, the second clamping member 30, the reinforcing member 40 and the holding member 80 are formed by bending a flat plate-shaped member by press processing or the like, but the manufacturing method of these members is not limited to press processing, and they may also be manufactured by forging, casting or other methods.

[0064] Furthermore, in each of the above embodiments, the fixing means 70 is provided on the reinforcing member 40, but an embodiment in which the reinforcing member 40 is not used is also conceivable. When the reinforcing member 40 is omitted, the fixing means 70 can be provided on, for example, a member corresponding to the top surface portion 41 of the reinforcing member 40 extended from the first clamping member 20 or the second clamping member 30 or the holding member 80. In any of the embodiments, the fixing means 70 is not limited to the bolt shaft 71 as shown in FIG. 1 , and other means may be used.

[0065] Furthermore, in the above embodiments, the configuration of the support member 10 of this invention has been described using a folded-plate roof 1 as an example of a roofing or ceiling material for various buildings, but this invention can also be applied to structures other than the folded-plate roof 1. Examples of such structures include roofing or ceiling materials other than the folded-plate roof 1, various wall members, beam members, and column members. In the first to fourth embodiments, this invention can be employed in structures having protrusions 2 on the surface of the members, and in the fifth to seventh embodiments, this invention can be applied to various structures regardless of the presence or absence of protrusions 2. In this case, various equipment attached to the structure may be above, to the side, or below the members that make up the structure. [Explanation of symbols]
