Description

[Technical Field]

[0001] The present invention relates to a mounting fixture for mounting a member to be mounted, such as a folded-plate roofing material, to a structural member of a building. [Background technology]

[0002] Traditionally, the construction of corrugated roofs has typically involved welding a support member called a tight frame to the structural material of the roof, and then attaching the corrugated roof material (the roof material used to form the corrugated roof) to the tight frame fixed to the structural material using fastening members such as bolts and nuts.

[0003] However, welding tight frames to structural materials requires experienced workers and welding equipment, and the area around the construction site must be protected from welding sparks. Furthermore, because the finished product depends on the skill of the welding worker, variations in the joint strength of tight frames are likely to occur.

[0004] Furthermore, in the construction industry, where a shortage of craftsmen has become a problem in recent years, there is a demand for simplified construction methods that do not require welding. For roofing material mounting equipment used in this industry, a type known as a weldless tight frame has already been developed, which can secure roofing materials to structural materials without the use of welding.

[0005] For example, Patent Document 1 (Figures 1 and 3) discloses an architectural bracket as such an attachment device, which has two locking members A for gripping a structural material 8, and a support member consisting of a receiving body 2 and a base 1 to which a folded-plate roof panel 9 is fixed, with the base 1 fixing the locking members A with two fastening means, and the base 1 fixing the receiving body 2 with two fastening means, so that the folded-plate roof panel 9 is attached to the structural material 8 via the receiving body 2, base 1 and locking members A.

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-6271 Summary of the Invention [Problem to be solved by the invention]

[0007] With the construction support tool disclosed in Patent Document 1, the work of fixing a structural material to the construction support tool requires the work of gripping the structural material 8 with the locking member A and, separately, the work of fastening the locking member A to the base 1 with a fastening means. In contrast, one object of the present invention is to obtain a mounting tool that can simultaneously perform the work of gripping the structural material with the gripping member and fastening the gripping member to a support member (which may be a base) when attaching a member to a structural material.

[0008] Furthermore, in the construction receiving tool disclosed in Patent Document 1, the base 1 fixes the receiving body 2 with two fastening means, thereby preventing the receiving body 2 from rotating relative to the base 1.

[0009] In contrast, another or additional object of the present invention is to provide a mounting device that can prevent the body member from rotating relative to the base even when the body member is fixed to the base by a single fixing means. [Means for solving the problem]

DETAILED DESCRIPTION OF THE INVENTION

[0013] The present invention will be described below.Unless otherwise specified, it should be understood that the terms used in this specification are used in the meanings generally used in the relevant field.Therefore, unless otherwise defined, all technical terms and scientific terms used in this specification have the same meaning as those generally understood by those skilled in the art to which this invention belongs.In the event of any discrepancy, this specification (including definitions) shall prevail.

[0014] In this specification, the term "about" refers to a range of ±10% of the following number.

[0015] Fig. 1 is a diagram for explaining the mounting device 1 of the present invention, Fig. 1(a) shows a folded-plate roof R mounted on a structural material (e.g., H-shaped steel Hsm) using the mounting device 1 of the present invention, and Fig. 1(b) conceptually shows the mounting device 1 of the present invention fixed to the structural material to support the folded-plate roof R. Fig. 2 is a diagram schematically showing the structure of the mounting device 1 of the present invention, Fig. 2(a) shows a case in which the mounting device 1 includes, as constituent elements, a support member 10 (in which the main body member and base member are integrated) and gripping members 12a, 12b, and Fig. 2(b) shows a case in which the support member 10 of the mounting device 1 is separated into two parts, a main body member 11 and a base member 13.

[0016] The mounting device 1 of the present invention is a device for mounting a workpiece R to a structural material Hsm, as shown in Figure 1, and the present invention is directed to a mounting device that, as shown in Figures 1 and 2, comprises a support member 10 for supporting the workpiece R, two gripping members (first and second) 12a, 12b that are movable relative to the support member and for gripping the structural material, and a fastening means 14 that fastens the two gripping members to the support member 10, and the first gripping member 12a and the second gripping member 12b are configured to grip the structural material Hsm as the fastening means 14 progresses.

[0017] The present invention is characterized in that in such a mounting device, the direction in which the structural material Hsm is gripped by the first gripping member 12a and the second gripping member 12b is approximately aligned with the direction Y (the left-right direction on the paper in FIG. 2) in which the first gripping member 12a and the second gripping member 12b are fastened by the fastening means 14, and this feature realizes a mounting device 1 that can be firmly fixed to the structural material R. In this specification, approximately aligned means that one direction is within a range of about ±10° from the other direction.

[0018] Therefore, in the mounting device 1 of the present invention, as long as the two gripping members 12a, 12b have the above-mentioned characteristics, the other configurations are not limited, and the specific configurations of the support member 10 and the fastening means 14 are also not limited.

[0019] For example, the support member 10 may be configured as a single inseparable part, as shown in Figure 2(a), in which the gripping portion of the structural material and the part that supports the attached member are integrated, or as shown in Figure 2(b), in which the gripping portion of the structural material and the part that supports the attached member are connected by two assembleable parts, or even in which three or more assembleable parts are connected by one another. (Configuration of gripping member) The gripping members can take various forms depending on the type of structural material. Basically, the mounting fixture includes at least a first gripping member and a second gripping member. The first gripping member and the second gripping member are each movable relative to the support member and fastened to the support member by a fastening mechanism. Because the first gripping member and the second gripping member are each movable relative to the support member, this configuration offers the advantage of being adaptable to structural materials of various sizes (e.g., H-shaped steel beams and C-shaped steel beams of different sizes) compared to cases where the first gripping member or the second gripping member is pre-fixed to the support member by welding or other means during the manufacturing stage of the mounting fixture. Furthermore, during maintenance after installation of the mounting fixture (e.g., when repairing a portion of a roof damaged by a strong wind or other factor), it is possible to replace only the damaged portion of either the gripping member or the support member, thereby reducing maintenance costs. Furthermore, in the present invention, the first gripping member and the second gripping member can be fastened by a single fastening means, which simplifies the construction work and reduces the time required compared to the conventional case where two fastening means are required. Representative embodiments are described below.

[0020] - When the structural material is H-shaped steel The first gripping member and the second gripping member are each capable of abutting against both side ends of one of a pair of flat plate portions of the H-shaped steel material, and the fastening means includes a fastening member that connects the first gripping member, the second gripping member, and the support member, and the first gripping member, the second gripping member, and the fastening means are arranged so that the first gripping member and the second gripping member approach each other as the fastening of the fastening means progresses, thereby allowing the H-shaped steel material to be gripped by the first gripping member and the second gripping member.

[0021] Here, the portion of the first gripping member 12a that grips the H-shaped steel material (gripping portion 2a) and the portion of the second gripping member 12b that grips the H-shaped steel material (gripping portion 2b) may have a single flat surface that abuts against one side edge of one of a pair of parallel flat plate portions of the H-shaped steel material. Alternatively, at least one of the gripping portions for gripping the H-shaped steel material of the first gripping member and the second gripping member may have a shape with multiple surfaces (e.g., an L-shape or a U-shape as shown in FIG. 2) that abuts against one side edge of one of the flat plate portions. This shape allows the end of the steel material to be more firmly hooked. The first gripping member and the second gripping member may be a pair of the same shape, or they may have different shapes.

[0022] - When the structural material is C-shaped steel The first gripping member is capable of contacting one end of the C-shaped steel material, and the second gripping member is capable of contacting the other end of the C-shaped steel material. The fastening means includes a first fastening member that is capable of pressing the first gripping member against one end of the C-shaped steel material, and a second fastening member that is capable of pressing the second gripping member against the other end of the C-shaped steel material. The first gripping member, the second gripping member, and the fastening means are arranged so that the first gripping member and the second gripping member move apart as the fastening means progresses, allowing the C-shaped steel material to be gripped by the first gripping member and the second gripping member.

[0023] Here, for example, the surface of the first gripping member gripping the C-shaped steel material (hereinafter referred to as the gripping portion) and the second gripping member gripping the C-shaped steel material that abuts against one side end of the C-shaped steel material may be a single flat surface, or at least one of the first gripping member gripping the C-shaped steel material and the second gripping member gripping the C-shaped steel material may have a shape with multiple surfaces that abut against one side end of the C-shaped steel material (for example, an L-shape or a U-shape as shown in FIG. 2). By using such a shape, it becomes possible to more firmly hook onto the end of the steel material. Furthermore, in the present invention, when fixing a support member (particularly a base member) to a structural material, by using a fastening means, it becomes possible to obtain stable construction accuracy regardless of the worker's skill, compared to conventional fixing by welding.

[0024] Furthermore, the fastening means may include a first fastening member that fastens one of the gripping members to the base member so that the gripping portion of the one gripping member is pressed against one of the folded end portions of the C-shaped steel material, and a second fastening member that fastens the other gripping member to the base member so that the gripping portion of the other gripping member is pressed against the other of the folded end portions of the C-shaped steel material. Note that the first and second fastening means are generally a pair of bolt 14a and nut 14b as shown in Figure 2(b), but the number of pairs of bolt and nut may be one or more, or may be just a bolt, or other devices such as a rivet or a buckle using a lever that clamps and fastens two members together.

[0025] (Configuration of support member) When the support member has an engaging protrusion that abuts against the gripping member Furthermore, when the structural material is a C-shaped steel, the support member preferably includes an engaging protrusion disposed on a path of movement of the first gripping member or the second gripping member as the fastening progresses, and the engaging protrusion is configured to prevent the movement of the first gripping member or the second gripping member with a force equal to or less than the first fastening force of the fastening means, and to release the prevention of the movement of the first gripping member or the second gripping member with a second fastening force greater than the first fastening force. Here, the first fastening force refers to the maximum force that the engaging protrusion can exert to prevent the movement of the first gripping member or the second gripping member as the fastening progresses. Therefore, when a second fastening force greater than the first fastening force is applied, the engaging protrusion will no longer be able to prevent the movement of the first gripping member or the second gripping member as the fastening progresses, and the first gripping member or the second gripping member will move over or break the engaging protrusion and move. By providing the engaging protrusion, a temporary fastening state can be achieved in which the first gripping member and the second gripping member are positioned at a predetermined distance using a force equal to or less than the first fastening force, and by putting the mounting tool into a temporary fastening state before construction work begins, the efficiency of the work of attaching the mounting tool to the C-shaped steel material can be improved. The engaging protrusion may be made of the same material as the support member, or may be made of a material (such as resin) that is weaker in strength than the support member.

[0026] When the support member includes a main body member and a base member As shown in FIG. 2(b), the support member 10 is composed of two members: a main body member 11 to which the attached member is fixed, and a base member 13 to which the structural member Hsm is fixed. The main body member may be fixed to the base member by a fastening means 15. Here, the fastening means 15 may take any form. For example, it may be fastened by adhesive or a set of a bolt 14a and a nut 14b. The set of bolt and nut may be one set or two or more sets. It may be just a bolt. In addition to a bolt and nut, it may also be a device that clamps and fastens two members with two clamping pieces, such as a rivet or a buckle using a lever.

[0027] In this case, it is preferable that base member 13 be provided with a rotation prevention mechanism that prevents main body member 11 from rotating relative to base member 13 around the axis of fastening means 15. By providing a rotation prevention mechanism, even when fastening is performed using a single fastening means, it is possible to avoid changes in posture due to rotation of the main body member relative to the base member around the axis of fastening means 15, thereby improving the fastening strength of the attached member to the structural material. As a result, it is possible to prevent the attached member from becoming detached from the structural material even due to strong winds such as those caused by typhoons. The specific configuration of the rotation prevention mechanism is not limited, and it is sufficient that it can prevent the main body member from rotating relative to the base member around the axis of the fastening means that connects the main body member and the base member.

[0028] One example of the configuration of the rotation prevention mechanism is one that has a regulating portion formed on the base member, and is configured to prevent the main body member from rotating around the axis of the fixing means relative to the base member by abutting the main body member against the regulating portion.

[0029] In particular, when the structural material is an H-shaped steel material, the main body member may have two opposing side walls, the base member may have two overlapping surfaces that can overlap with the flat surfaces of the two opposing side walls (first vertical piece and second vertical piece) of the main body member by fastening means, and two non-overlapping surfaces adjacent to each of the overlapping surfaces, and the regulating portion may be at least one flange portion formed on at least one of the two non-overlapping surfaces.

[0030] Furthermore, when the structural material is a C-shaped steel material, the main body member may have two opposing side walls, the base member may have two overlapping surfaces that can overlap with the flat surfaces of the two opposing side walls (first vertical piece and second vertical piece) of the main body member by fastening means, and the regulating portion may be a protrusion formed on at least one of the two overlapping surfaces that protrudes in a direction approximately perpendicular to the overlapping surface and can abut against the main body member.

[0031] 2(b), the fastening means 14 may be one or more sets of bolts and nuts, may be just a bolt, or may be a fastening means that fastens two members by clamping them with two clamping pieces, such as a rivet or a buckle that uses a lever. The fastening means may penetrate the support member or a base member that constitutes the support member, or it may not penetrate the support member or a base member that constitutes the support member.

[0032] Furthermore, the attached members and structural materials can be in any form. For example, structural materials can be materials that form the structure that supports a building, including H-shaped steel, C-shaped steel, and square steel used as pillars or beams.

[0033] Furthermore, if the structural material is a member that serves as the base for a roof (e.g., a beam), the member to be attached may be a roof (e.g., a folded-plate roof), and if the structural material is a member that serves as the base for a wall (e.g., a pillar), the member to be attached may be a wall member.

[0034] As explained above, the mounting device of the present invention is not particularly limited in its configuration as long as the direction in which the structural material is gripped by the first and second gripping members is approximately the same as the direction Y (left-to-right direction on the paper in Figure 2) in which the first and second gripping members are fastened by the fastening means. In the following description of the embodiments, however, as embodiment 1, a mounting device 100 applicable to H-shaped steel material in which the support member includes a main body member and a base member is given, as a variant of embodiment 1, a mounting device 101a in which the main body member and base member in mounting device 100 of embodiment 1 are integrated into a single member, and as embodiment 2, a mounting device 200 applicable to C-shaped steel material in which the support member includes a main body member and a base member is given.

[0035] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0036] [Embodiment 1] FIG. 3 is a perspective view for explaining a mounting fixture 100 according to embodiment 1 of the present invention, showing the appearance of the mounting fixture 10. FIG. 4 is a perspective view showing the state in which the mounting fixture 100 shown in FIG. 3 is fixed to an H-shaped steel material Hsm as a structural material. FIG. 5 is a six-sided view of the mounting fixture 100 shown in FIG. 3, and FIGS. 5(a) to 5(f) respectively show the structure of the mounting fixture 100 when viewed from directions A, B, C, D, E, and F (six directions: front, back, left, right, top, and bottom) of the reduced mounting fixture 100 (FIG. 5(g)). In FIG. 5, the view from direction C is taken as the front view.

[0037] This mounting fixture 100 is a fixture for mounting a member to be mounted to a structural material, the structural material being an H-beam steel material Hsm, and the member to be mounted being a folded-plate roof R.

[0038] The mounting device 100 includes a body member 110, a base member 130, two gripping members 120a, 120b, a fastening means 140, and a fixing means 150.

[0039] Here, the main body member 110 is a member that receives the folded-plate roof R, and is supported by the base member 130 , and the base member 130 and the main body member 110 are connected by a fixing means 150 .

[0040] Here, the fixing means 150 includes a connecting bolt 151 that passes through the base member 130 and the main body member 110, and a connecting nut 152 that is attached to the connecting bolt 151.

[0041] One gripping member 120a is a first gripping member having two gripping portions 121b, 122b that abut one portion of the H-shaped steel Hsm, and the other gripping member 120b is a second gripping member having two gripping portions 121b, 122b that abut the other portion of the H-shaped steel Hsm. The gripping portions 121b, 122b of the gripping members 120a, 120b are roughly U-shaped. These gripping members 120a, 120b are fastened to the base member 130 by fastening means 140, so that the roughly U-shaped surfaces of the gripping portions 121b, 122b abut and hook onto the structural material Hsm. This allows the gripping members 120a, 120b to firmly grip the structural material Hsm.

[0042] Here, the fastening means 140 includes a fastening bolt 141 that passes through the base member 130 and a fastening nut 142 attached thereto, and these bolts 141 and nuts 142 fasten the two gripping members 120a, 120b to the base member 130, so that the base member 130 can be fixed to the H-shaped steel material Hsm together with the two gripping members 120a, 120b.

[0043] More specifically, the gripping portions 121b, 122b of the first gripping member 120a hook onto one side end of one of a pair of parallel flat plate portions of the H-shaped steel material Hsm (the flat plate portion on the upper side of the paper in Figure 2), and the gripping portions 121b, 122b of the second gripping member 120b hook onto the other side end of the upper flat plate portion of the H-shaped steel material Hsm, and the fastening means 140 is capable of tightening the two gripping members so that the gripping portions 121b, 122b of the two gripping members 120a, 120b clamp the upper flat plate portion of the H-shaped steel material.

[0044] In the mounting fixture 100 of this embodiment 1, the direction Y (the left-right direction on the paper in Figure 5(d)) in which the pair of gripping members 120a, 120b grip the H-shaped steel material Hsm is approximately the same as the direction Y in which the fastening means fastens.

[0045] In this way, the direction Y in which the two gripping members 120a, 120b grip the H-shaped steel Hsm and the direction Y in which the fastening means fasten the steel can be achieved in a single operation. As a result, construction time can be significantly reduced compared to conventional work. Furthermore, the number of points where the gripping members are fastened to the base is reduced from two to one, which also reduces component costs.

[0046] Furthermore, the two gripping members 120a, 120b can be formed by punching and bending a plate-like material such as a stainless steel plate or an iron steel plate, and the gripping portions 121b, 122b of the two gripping members 120a, 120b are configured so that the direction of their plate thickness is in a direction X (a direction perpendicular to the paper surface of FIG. 5(d)) that is approximately perpendicular to the direction in which the two gripping members grip the H-shaped steel material Hsm. As a result, the gripping portions 121b, 122b can withstand a large clamping force despite their lightweight structure. In this specification, "approximately perpendicular" refers to a range of 90°±approximately 20°.

[0047] FIG. 6 is an exploded perspective view of the mounting device 100 shown in FIG. 3, broken down into its individual components.

[0048] 6, in this mounting fixture 100, the fastening bolt 141 is attached with the fastening nut 142 in a state in which it passes through the second gripping member 120b, the base member 130, and the first gripping member 120a in that order. Therefore, when the mounting fixture 100 is placed on the upper flat plate portion of the H-shaped steel material Hsm (see FIG. 11), and the fastening nut 142 is tightened around the fastening bolt 141, the gripping portions 121b, 122b of the gripping members 120a, 120b come into contact with both ends of the upper flat plate portion of the H-shaped steel material Hsm, and at the same time, the first gripping member 120a and the second gripping member 120b are fastened to the base member 130. The width of the base member 130 in the fastening direction is set taking into consideration the width of the upper flat plate portion of the H-shaped steel material Hsm and the dimensions of the two gripping members 120a, 120b in the fastening direction so that the gripping portions 121b, 122b of the two gripping members 120a, 120b clamp the upper flat plate portion of the H-shaped steel material Hsm with sufficient force.

[0049] Next, each of the components constituting the mounting device 100 of the first embodiment will be described in detail.

[0050] (Main body member 110) Fig. 7 is a six-view diagram of the main body member 110 shown in Fig. 6, and Fig. 7(a) to Fig. 7(f) respectively show the structure of the main body member 110 when the reduced main body member 110 (Fig. 7(g)) of Fig. 6 is viewed from directions A, B, C, D, E, and F (six directions: front, back, left, right, top, and bottom). In Fig. 7, the view from direction A is the front view.

[0051] This main body member 110 is constructed by bending a long, narrow, rectangular steel plate (stainless steel or iron steel) into an approximately U-shape, and includes two opposing side walls (a first vertical piece 111 and a second vertical piece 112) and a top plate portion 113 connected to these vertical pieces 111 and 112.

[0052] That is, one end of the top plate portion 113 is connected to the upper edge of the first vertical piece 111, and the other end of the top plate portion 113 is connected to the upper edge of the second vertical piece 112, and the top plate portion 113, the first vertical piece 111, and the second vertical piece 112 have cross-sectional concave grooves formed along their longitudinal direction for reinforcement.

[0053] Furthermore, in the top plate portion 113, the component mounting portion 113a, where components such as retaining clips that support the roof material are attached, is lower than other portions of the top plate portion 113, and the component mounting portion 113a is formed with a fixing bolt hole 113a1 into which a fixing bolt 161 for attaching components such as retaining clips is inserted.

[0054] Furthermore, the first vertical piece 111 and the second vertical piece 112 have connecting bolt holes 111a, 112a formed at their lower ends, into which connecting bolts 151 for connecting the main body member 110 to the base member 130 are inserted.

[0055] (Base member 130) Figure 8 is a six-sided view of the base member 130 shown in Figure 6, and Figures 8(a) to 8(f) respectively show the structure of the base member 130 when the reduced-size base member 130 (Figure 8(g)) of Figure 6 is viewed from directions A, B, C, D, E, and F (six directions: front, back, left, right, top, and bottom). In Figure 8, the view from direction A is taken as the front view.

[0056] This base member 130 is made by bending a plate-shaped steel material (stainless steel material or iron steel material) that has been punched into a predetermined shape to form a roughly rectangular box-shaped body (without a bottom), and has a roughly rectangular base top plate 135 and four side walls 131 to 134.

[0057] Here, the two opposing side walls 131, 132 serve as gripping fastening walls for fastening the two gripping members 120a, 120b together, and another pair of opposing side walls 133, 134 serve as main body connecting walls 133, 134 for connecting the two vertical pieces 111 and 112 of the main body member 110. Here, the main body connecting walls 133, 134 form an overlapping surface that overlaps with the plane formed by the first vertical piece 111 and the second vertical piece 112 of the main body member 210.

[0058] The four side walls, namely, the grip fastening walls 131 and 132 and the main body connecting walls 133 and 134, extend downward from the top plate portion 135 in a direction perpendicular to the top plate portion 135.

[0059] The opposing grip fastening walls 131 and 132 are connected to opposing side edges (long sides) of the approximately rectangular top plate portion 135, and fastening bolt holes 131a and 132a are formed in the approximate center of each grip fastening wall 131 and 132 for inserting a fastening bolt 141.

[0060] The opposing main body connecting walls 133, 134 are connected to opposing side edges (short sides) of a generally rectangular top plate portion 135, and connecting bolt holes 133a, 134a for inserting connecting bolts 151 are formed in the upper part of each main body connecting wall 133, 134 from the center. The main body connecting walls 133, 134 have two overlapping surfaces that overlap with the surfaces (flat surfaces) of the first vertical piece 111 and the second vertical piece 112 of the main body member 110, and the grip fastening walls 131 and 132 have two non-overlapping surfaces that do not overlap with the surfaces (flat surfaces) of the first vertical piece 111 and the second vertical piece 112 of the main body member 110, and these overlapping surfaces and non-overlapping surfaces are arranged adjacent to each other.

[0061] In this base member 130, both side edges of the gripping fastening walls 131, 132 extend outward beyond the side ends of the main body connecting walls 133, 134 to form flanges (restricting portions) 131b, 132b. When the front vertical piece 111 and the rear vertical piece 112 of the main body member 110 are connected to the main body connecting walls 233, 234 of the base member 130, these flanges 131b, 132b are able to abut against both side edges of the front vertical piece 111 and the rear vertical piece 112, thereby preventing the main body member 110 from rotating around the axis of the connecting bolt 151 relative to the base member 130.

[0062] (First gripping member 120a) Figure 9 is a six-view diagram of the first gripping member 120a shown in Figure 6, and Figures 9(a) to 9(f) respectively show the structure of the first gripping member 120a when viewed from directions A, B, C, D, E, and F (six directions: front, back, left, right, top, and bottom) of the reduced first gripping member 120a (Figure 9(g)) in Figure 6. Note that in Figure 9, the view from direction A is the front view.

[0063] This first gripping member 120a is made, for example, by bending a plate-shaped steel material (stainless steel material or iron steel material) obtained by punching into a predetermined shape so that it has an approximately U-shape as shown in Figures 9(e) and 9(f).

[0064] The first gripping member 120a has a gripping base 123 and two opposing gripping side walls (first and second gripping side walls) 121, 122.

[0065] Grip base 123 is a portion that connects grip side walls 121, 122, and includes a substantially rectangular bolt attachment portion 123a, a folded upper reinforcing piece 123b formed on the upper edge of bolt attachment portion 123a, and a folded lower reinforcing piece 123c formed on the lower edge of bolt attachment portion 121a. Both side edges of bolt attachment portion 123a are connected to one end of grip side walls 122 and 123, and a bolt attachment hole 123a1 for inserting a fastening bolt 141 is formed in the center of bolt attachment portion 123a.

[0066] The first gripping side wall 121 has an abutment portion (hooking portion) 121b that abuts and hooks onto one end edge of the upper flat plate portion of the H-shaped steel material Hsm, and a gripping support portion 121a that supports the abutment portion 121b against the gripping base portion 123.

[0067] Like the first gripping side wall 121, the second gripping side wall 122 has an abutment portion (hooking portion) 122b that abuts and hooks onto the other end edge of the upper flat plate portion of the H-shaped steel material Hsm, and a gripping support portion 122a that supports the abutment portion 122b against the gripping base 122.

[0068] (Installation procedure for the installation fixture 100) Next, a procedure for attaching the above-described mounting fixture 100 to the H-beam steel Hsm will be described.

[0069] Fig. 10 is a perspective view showing how the mounting fixture 100 shown in Fig. 3 is placed on the H-shaped steel Hsm, and Fig. 11 is a perspective view showing the state in which the mounting fixture 100 shown in Fig. 3 has been placed on the H-shaped steel Hsm. Fig. 12 is a diagram for explaining how the gripping members 120a, 120b of the mounting fixture 100 shown in Fig. 3 grip the H-shaped steel Hsm, and Fig. 12(a) and Fig. 12(b) respectively show the state before fastening by the fastening means 140 (Fig. 12(a)) and the state after fastening (Fig. 12(b)).

[0070] First, as shown in Figure 10, the fastening nut 142 is loosened from the fastening bolt 141, and the mounting fixture 100 is placed on the upper surface of the H-shaped steel material Hsm with a gap Td between the gripping portions 121b, 122b of the first gripping member 120a and the gripping portions 121b, 122b of the second gripping member 120b that is equal to or greater than the width Hw of the upper flat plate portion (top surface portion) of the H-shaped steel material Hsm. At this time, since the distance Td between the gripping portions 121b, 122b of the first gripping member 120a and the gripping portions 122b, 121b of the second gripping member 120b is greater than the width Hw of the upper flat portion (top wall) of the H-shaped steel material Hsm, the top wall of the H-shaped steel material Hsm passes between the two gripping members 120a, 120b, and as shown in Figure 11, the mounting device 100 is placed on the H-shaped steel material Hsm with the base member 130 abutting the top wall of the H-shaped steel material Hsm.

[0071] 12(a), with the mounting fixture 100 placed on the H-shaped steel material Hsm, tightening the fastening nut 142 to the fastening bolt 141 pulls the left and right gripping members 120a, 120b together, causing the gripping portions 121b, 122b of the first gripping member 120a and the gripping portions 122b, 121b of the second gripping member 120b to hook onto and abut the ends of the top wall of the H-shaped steel material Hsm. In this state, tightening the fastening nut 142 with a predetermined tightening force fixes the two gripping members 120a, 120b to the H-shaped steel material Hsm with a predetermined strength.

[0072] In this case, the fastening direction Y in which the two gripping members 120a, 120b are fastened to the base member 130 by the fastening bolt 141 and the fastening nut 142 is approximately perpendicular to the thickness direction X of the plate material that is the constituent member of the gripping portions 121b, 122b of the gripping members 120a, 120b, so that the gripping portions 121b, 122b of the gripping members 120a, 120b can withstand a large tightening force despite their lightweight structure.

[0073] As described above, in the mounting fixture 100 of embodiment 1, the direction in which the two gripping members 120a, 120b grip the H-shaped steel material Hsm is approximately the same as the fastening direction Y (left-right direction on the paper in FIG. 2) by the fastening means 140, and the thickness direction X (direction perpendicular to the paper in FIG. 2) of each gripping portion 121b, 122b of the gripping members 120a, 120b is configured to be approximately perpendicular to the direction Y when the two gripping members 120a, 120b grip the H-shaped steel material Hsm, so that the lightweight mounting fixture 100 can be firmly fixed to the H-shaped steel material Hsm.

[0074] Furthermore, in the mounting device 100 of this first embodiment, the base member 130 has the function of preventing the main body member 110 from rotating around the axis of the connecting bolt 151 relative to the base member 130 .

[0075] Figure 13 is a diagram for explaining the mechanism by which relative rotation of the main body member 110 with respect to the base member 130 in the mounting device 100 shown in Figure 3 is prevented, with Figures 13(a) and 13(b) being an oblique view and a side view showing the positional relationship of the main body member 110 with respect to the base member 130, and Figures 13(c) to 13(e) showing how the above-mentioned relative rotation is prevented.

[0076] In this mounting device 100, as shown in FIG. 13, both side edges of gripping fastening walls 131, 132 of the base member 130 (walls whose surfaces are non-overlapping surfaces that do not overlap with the surfaces of the vertical pieces 111, 112 of the main body member 110) extend outward beyond the side ends of the main body connecting walls 133, 134 (walls whose surfaces are overlapping surfaces that overlap with the surfaces of the vertical pieces 111, 112 of the main body member 110) to form flanges 131b, 132b. When the front vertical piece 111 and the rear vertical piece 112 of the main body member 110 are connected to the main body connecting walls 133 and 134 of the base member 130 (see Figures 13(a) to (c)), the flange portions 131b and 132b abut against both side edges of the front vertical piece 111 and the rear vertical piece 112, thereby preventing the main body member 110 from rotating in any direction around the axis of the connecting bolt 151 relative to the base member 130, as shown in Figures 13(d) and (e).

[0077] By providing such a structure that prevents rotation, it is no longer necessary to use two sets of fastening means (for example, bolts and nuts) to prevent rotation when connecting main body member 110 and base member 130, and it is possible to achieve rotation prevention even when connecting with a single set of fastening means (for example, bolts and nuts). As a result, it is possible to significantly reduce the work time required for construction and the cost of parts.

[0078] Furthermore, in the mounting fixture 100 of this embodiment 1, the main body member 110, the base member 130, and the two gripping members 120a, 120b are connected with bolts, so that the size of the mounting fixture 100 can be flexibly changed to match the height of the roof material, the size of the H-shaped steel material Hsm, etc.

[0079] Specifically, to adjust the size of the mounting fixture 100 to match the height of the roof material, simply change the main body member 110 to one of an appropriate size that matches the height of the roof material, and to adjust the size of the mounting fixture 100 to match the size of the H-shaped steel material Hsm, simply select the length of the gripping arms 122a, 123a of the gripping members 120a, 120b, or the dimensions of the base member 130 as a box body, to match the size of the H-shaped steel material Hsm.

[0080] In contrast, if the mounting fixture 100 has an integrated structure of the main body member 110 and the base member 130, it is necessary to prepare many parts of different sizes to accommodate differences in the height of the roof material or the size of the H-shaped steel material Hsm.

[0081] For example, in the mounting device 100 of this embodiment 1, three different sizes of main body members 110 can be used to accommodate three different roof material heights, and three different sizes of base members 130 can be used to accommodate three different sizes of H-shaped steel Hsm.In other words, it is sufficient to prepare three different sizes of main body members 110 and base members 130.

[0082] In contrast, if the main body member 110 and base member 130 are integrated as a support member, in order to accommodate three different roof material heights and three different sizes of H-shaped steel Hsm, three support members 10 must be prepared so that one type of roof material height can accommodate three different sizes of H-shaped steel Hsm, which ultimately means that nine types of support members must be prepared.

[0083] However, such an arrangement in which the main body member 110 and the base member 130 in the mounting device 100 of embodiment 1 are integrated as a support member may be effective depending on the application because it simplifies the structure and has a small number of parts, and this will be specifically described below as a modified example of embodiment 1.

[0084] [Modification of the first embodiment] FIG. 14 is a diagram illustrating a mounting fixture 100a according to a modified example of the first embodiment of the present invention. 14(a) is a front view corresponding to FIG. 5(c) used in the description of embodiment 1, FIG. 14(b) is a side view corresponding to FIG. 5(b), and FIG. 14(c) is a top view corresponding to FIG. 5(e). In particular, FIG. 14 shows the state in which this mounting device 100a is placed on the top wall of the H-shaped steel material Hsm with the fastening nut 142 loosened, as shown in FIG. 12(a) of embodiment 1.

[0085] Mounting device 100a according to this modification has support member 101a formed by integrating main body member 110 and base member 130 in mounting device 100 of embodiment 1, instead of these, and further has auxiliary member 101b that reinforces support member 101a, and two gripping members 120a, 120b are fastened to the lower end of support member 101a by fastening means 140; the rest of the configuration is the same as in mounting device 100 of embodiment 1. In Fig. 14, 106 is a fixing bolt for attaching a workpiece to support member 101a, and corresponds to fixing bolt 161 described in embodiment 1.

[0086] Here, the auxiliary member 101b is joined to the support member 101a using screws, adhesive, or welding at the factory, and this mounting device 100a does not require joining of the auxiliary member 101b to the support member 101a at the construction site.

[0087] With mounting fixture 100a having such a structure, it is not possible to select different sizes for main body member 110 and base member 130 as in embodiment 1, but on the other hand, phenomena such as rotation of main body member 110 relative to base member 130, as occurs with mounting fixture 100 of embodiment 1, do not occur, and mounting fixture 100a can be made more compact in configuration without the need for an anti-rotation mechanism.

[0088] [Embodiment 2] FIG. 15 is a perspective view for explaining a mounting fixture 200 according to a second embodiment of the present invention, showing the appearance of the mounting fixture 200. FIG. 16 is a perspective view showing the state in which the mounting fixture 200 shown in FIG. 15 is fixed to a C-shaped steel material Csm as a structural material. FIG. 17 is a six-view diagram of the mounting fixture 200 shown in FIG. 15, and FIGS. 17(a) to 17(f) respectively show the structure of the mounting fixture 200 when viewed from directions A, B, C, D, E, and F (six directions: front, back, left, right, top, and bottom) of the reduced mounting fixture 200 (FIG. 17(g)) in FIG. 15. In FIG. 17, the view from direction C is taken as a front view.

[0089] This mounting fixture 200 is a fixture for mounting a mounted member to a structural material, the structural material being a C-shaped steel member Csm, and the mounted member being a folded-plate roof R.

[0090] In other words, this mounting fixture 200 has a structure for gripping C-shaped steel material Csm instead of the structure for gripping H-shaped steel material Hsm in the mounting fixture 100 of embodiment 1, and has a main body member 210, a base member 230, two gripping members (a first gripping member 220a and a second gripping member 220b), two fastening means (a first fastening means 240a and a second fastening means 240b), and a fixing means 250.

[0091] Here, the main body member 210 and the fixing means 250 have the same configuration as the main body member 110 and the fixing means 150 in embodiment 1, but the base member 230, the two gripping members 220a, 220b, and the two fastening means 240a, 240b are different from the corresponding parts in embodiment 1, i.e., the base member 130, the two gripping members 120a, 120b, and the one fastening means 140.

[0092] Specifically, one gripping member 220a is a first gripping member having a gripping portion 221c that abuts against one end of the C-shaped steel material Csm, and the other gripping member 220b has a gripping portion 222c that abuts against the other end of the C-shaped steel material Csm.

[0093] Here, the first fastening means 240a includes a first fastening nut 241a that passes through the base member 230 and a first fastening nut 242a that is attached thereto, and the second fastening means 240b includes a second fastening bolt 241b that passes through the base member 230 and a second fastening nut 242b that is attached thereto, and these bolts 241a, 241b and nuts 242a, 242b fasten the gripping members 220a, 220b to the base member 230, so that the base member 230 can be fixed to the C-shaped steel material Csm together with the two gripping members 220a, 220b.

[0094] More specifically, the first fastening means causes the gripping portion 221c of the first gripping member 220a to hook onto one end of the C-shaped steel material Csm, and the second fastening means causes the gripping portion 222c of the second gripping member 220b to hook onto the other side end of the C-shaped steel material Csm. Furthermore, the first fastening means 240a is capable of fastening the first gripping member 220a to the base member 230 so that the gripping portion 221c of the first gripping member 220a is pressed against one end side with which it abuts. The second fastening means 240b is capable of fastening the second gripping member 220b to the base member 230 so that the gripping portions 221c, 222c of the second gripping member 220b are pressed against the other end side with which they abut.

[0095] In the mounting fixture 200 of this second embodiment, the direction Y in which the first gripping member 220a is pressed against the C-shaped steel material Csm (to the right in FIG. 17(d)) ​​coincides with the fastening direction Y of the first fastening means 240a, and the direction Y in which the second gripping member 220b is pressed against the C-shaped steel material Csm (to the left in FIG. 17(d)) ​​substantially coincides with the fastening direction Y of the second fastening means 240b. In other words, as fastening by the first fastening means and the second fastening means progresses, the first gripping member and the second gripping member move in directions away from each other, so that the first gripping member is pressed against one end of the C-shaped steel material and the second gripping member is pressed against the other end, and as a result, the first gripping member and the second gripping member can firmly grip the C-shaped steel material.

[0096] The thickness direction of the plate material constituting the gripping portions 221c, 222c of each gripping member 220a, 220b is configured to be in direction X (direction perpendicular to the paper surface of Figure 17(d)) ​​which is approximately perpendicular to direction Y when the two gripping members 220a, 220b grip the C-shaped steel material Csm.

[0097] FIG. 18 is an exploded perspective view of the mounting device 200 shown in FIG. 15, broken down into its individual components.

[0098] As can be seen from Figure 18, in this mounting fixture 200, the fastening bolt 241a has a fastening nut 242a attached to it while passing through the first gripping member 220a and the base member 230, and the fastening bolt 241b has a fastening nut 242b attached to it while passing through the second gripping member 220b and the base member 230.As a result, when the mounting fixture 200 is placed on the opening side of the C-shaped steel material Csm (see Figures 24 and 25), by tightening the fastening nuts 242a and 242b to the fastening bolts 241a and 241b, the gripping portions 222 of these gripping members 220a and 220b abut against the opposing ends of the C-shaped steel material Csm, and at the same time, the first gripping member 220a and the second gripping member 220b are fixed to the base member 230.

[0099] Next, each of the components constituting the mounting device 200 of the second embodiment will be described in detail.

[0100] (Main body member 210) Figure 19 is a six-view diagram of the main body member 210 shown in Figure 18, and Figures 19(a) to 19(f) respectively show the structure of the reduced main body member 210 (Figure 19(g)) of Figure 18 when viewed from directions A, B, C, D, E, and F (six directions: front, back, left, right, top, and bottom). In Figure 19, the view from direction A is the front view.

[0101] This main body member 210 has the same structure as the main body member 110 in the mounting fixture 100 of embodiment 1. Therefore, the first vertical piece 211, the second vertical piece 212, the top plate portion 213, the connecting bolt holes 211a and 212a, the component mounting portion 213a, and the fixing bolt hole 213a1 of this main body member 210 are the same as the first vertical piece 111, the second vertical piece 112, the top plate portion 113, the connecting bolt holes 111a and 112a, the component mounting portion 113a, and the fixing bolt hole 113a1 of the mounting fixture 100 shown in Fig. 7. In addition, the fixing means 250, which includes a connecting bolt 251 and a connecting nut 252 that connect the main body member 210 to the base member 230, is also the same as the fixing means 150, which includes the connecting bolt 151 and the connecting nut 152 of embodiment 1.

[0102] (Base member 230) Figure 20 is a six-view diagram of the base member 230 shown in Figure 18, and Figures 20(a) to 20(f) respectively show the structure of a reduced version of the base member 230 (Figure 20(g)) of Figure 18 when viewed from directions A, B, C, D, E, and F (six directions: front, back, left, right, top, and bottom). In Figure 20, the view from direction D is taken as the front view.

[0103] This base member 230 is made by punching out a plate-shaped steel material (stainless steel material or iron steel material) into a predetermined shape and bending it to form a roughly rectangular box-shaped body (without a bottom), and has a roughly rectangular base top plate 235 and four side walls 231 to 234.

[0104] Here, one set of two opposing side walls 231, 232 serves as gripping fastening walls for fastening the two gripping members 220a, 220b together, and the other set of two opposing side walls 233, 234 serves as main body connecting walls for connecting the two vertical pieces 211 and 212 of the main body member 210. The gripping fastening walls 231, 232 and the main body connecting walls 233, 234 extend downward from the top plate portion 213 in a direction perpendicular to the top plate portion 213. Here, the main body connecting walls 233, 234 each form an overlapping surface that can overlap with the flat surfaces of the opposing side walls 211, 212 of the main body member 210 by fixing means.

[0105] In addition, auxiliary walls 233e and 234e extending from the main body connecting walls 233 and 234 along the grip fastening wall 231 are arranged overlapping the grip fastening wall 231, and similarly, auxiliary walls 233ed and 234e extending from the main body connecting walls 233 and 234 along the grip fastening wall 232 are arranged overlapping the grip fastening wall 232.

[0106] The opposing grip fastening walls 231 and 232 are connected to opposing side edges (short sides) of the approximately rectangular top plate portion 113, and fastening bolt holes 231a and 232a are formed in the lower part of each grip fastening wall 231 and 232, toward the center, for inserting a fastening bolt 241.

[0107] Furthermore, the opposing main body connecting walls 233, 234 are connected to opposing side edges (longer sides) of the generally rectangular top plate portion 213, and connecting bolt holes 233a, 234a for inserting connecting bolts 251 are formed in the upper part of each main body connecting wall 233, 234 from the center. The lower ends of the main body connecting walls 233, 234 are bent outward, and the bent parts (lower bent parts) 233c, 234c serve as reinforcing parts for the main body connecting walls 233, 234.

[0108] In this base member 230, two sets of two restricting protrusions (restricting portions) 234b facing each other at a distance equivalent to the width of one of the opposing side walls (first vertical piece 211) of the main body member 210 are formed in two upper and lower rows on both sides of the connecting bolt hole 234a on the outer surface of the main body connecting wall 234. Similarly, two sets of two restricting protrusions (restricting portions) 233b facing each other at a distance equivalent to the width of the other opposing side wall (second vertical piece 212) of the main body member 210 are formed in two upper and lower rows on both sides of the connecting bolt hole 233a on the outer surface of the main body connecting wall 233.

[0109] These regulating protrusions 234b and 233b respectively function to prevent the main body member 210 from rotating around the axis of the connecting bolt 251 relative to the base member 230 by abutting against both side edges of the front vertical piece 211 and the rear vertical piece 212 when the front vertical piece (first vertical piece) 211 of the main body member 210 is connected to the main body connecting wall 234 of the base member 230 and the rear vertical piece (second vertical piece) 212 of the main body member 210 is connected to the main body connecting wall 233 of the base member 230.

[0110] In addition, an engagement protrusion 234d is provided on the inner surface of the main body connecting wall 234 so as to be positioned on the movement path along which the first gripping member 220a and the second gripping member 220b move as the fastening progresses, and similarly, an engagement protrusion 233d is provided on the inner surface of the main body connecting wall 233 so as to be positioned on the movement path along which the first gripping member and the second gripping member move as the fastening progresses.

[0111] These engaging protrusions are configured to prevent movement of the first gripping member 220a and the second gripping member 220b with a force equal to or less than the first fastening force of the fastening means 240, and to release the prevention of movement of the first gripping member 220a and the second gripping member 220b with a second fastening force greater than the first fastening force.

[0112] (First and second gripping members 220a, 220b) Figure 21 is a six-view diagram of the first gripping member 220a shown in Figure 18, and Figures 21(a) to 21(f) respectively show the structure of the first gripping member 220a (Figure 21(g)) in Figure 18 when viewed from directions A, B, C, D, E, and F (six directions: front, back, left, right, top, and bottom). In Figure 21, the view from direction A is the front view.

[0113] This first gripping member 220a is made, for example, by bending a plate-shaped steel material (stainless steel material or iron steel material) obtained by punching into a predetermined shape, and the first gripping member 220a has a gripping base 223 and two opposing gripping side walls (first and second gripping side walls) 221, 222, which are arranged on both sides of the gripping base 223.

[0114] The grip base 223 includes a substantially rectangular bolt attachment portion 223a, a folded upper reinforcing piece 223b formed on the upper edge of the bolt attachment portion 223a, and a folded lower reinforcing piece 223c formed on the lower edge of the bolt attachment portion 223a. The grip base 223a is a portion that connects the grip side walls 221 and 222, and both ends of the bolt attachment portion 223a are connected to one ends of the grip side walls 221 and 222. A fastening bolt hole 223a1 for inserting a fastening bolt 241 is formed in the center of the bolt attachment portion 223a.

[0115] The first gripping side wall 221 includes a side wall main body 221a, a side guide piece 221b, and an abutment portion 221c, the abutment portion 221b being a portion that abuts against and catches on one end of the C-shaped steel material Csm, and the side wall main body 221a being a portion that supports the abutment portion 221b against the gripping base 223. In the first gripping side wall 221, a notch 221d is formed spanning the abutment portion 221c and the side wall main body 221a, and one end of the C-shaped steel material Csm is accommodated within this notch 221d. In addition, the side guide piece 221b is a reinforcing part joined to the side wall main body 221a and the abutment part 221c so as to straddle them, and the side end of the side guide piece 221b moves along the inner surface of the main body connecting wall 233 or 234 of the base member 230 and engages with the engaging protrusion 233d or 234d formed on the inner surface of the main body connecting wall 233, 234.

[0116] The second gripping side wall 222 includes a side wall main body 222a, a side guide piece 222b, and an abutment portion 222c, the abutment portion 222c being a portion that abuts against and catches on the other end of the C-shaped steel material Csm, and the side wall main body 222a being a portion that supports the abutment portion 222c against the gripping base 223. In the second gripping side wall 222, a notch 222d is formed spanning the abutment portion 222c and the side wall main body 222a, and the other end of the C-shaped steel material Csm is accommodated within this notch 222d. In addition, the side guide piece 222b is a reinforcing part joined to the side wall main body 222a and the abutment portion 222c so as to straddle them, and the side end of the side guide piece 222b moves along the inner surface of the main body connecting wall 233 or 234 of the base member 230 and engages with the engaging protrusion 233d or 234d formed on the inner surface of the main body connecting wall 233 or 234.

[0117] Next, a procedure for attaching the above-mentioned mounting fixture 200 to the C-shaped steel member Csm will be described.

[0118] Fig. 22 is a perspective view showing the mounting fixture 200 shown in Fig. 15 being placed on the C-shaped steel material Csm, and Fig. 23 is a cross-sectional view showing the positions of the first gripping member 220a and the second gripping member 220b within the base member 230 of the mounting fixture 200 shown in Fig. 22. Fig. 24 is a perspective view showing the mounting fixture 200 shown in Fig. 15 placed on the C-shaped steel material Csm. Fig. 25 is a diagram showing the first gripping member 220a and the second gripping member 220b of the mounting fixture 200 shown in Fig. 15 housed in the opening of the C-shaped steel material Csm, Fig. 25(a) is a cross-sectional view, and Fig. 25(b) is a bottom view showing the mounting fixture 200 in Fig. 25(a) as viewed from the back side. 23 and 25, the main body member 210 of the mounting fixture 200 is omitted, and in FIG. 25(b), the C-shaped steel material Csm in FIG. 25(a) is also omitted.

[0119] First, when placing the mounting fixture 200 on the C-shaped steel material Csm as shown in Figure 22, as shown in Figure 23, the fastening nut 242a is tightened to the fastening bolt 241a with a first tightening force (temporary tightening force) to bring the side reinforcement pieces 221b, 222b of the first gripping member 220a into contact with the engaging protrusions 233b, 234b, and the fastening nut 242b is tightened to the fastening bolt 241b with a first tightening force (temporary tightening force) to bring the side reinforcement pieces 222b, 221b of the second gripping member 220b into contact with the engaging protrusions 233b, 234b (see Figure 25(b)).

[0120] This maintains a state in which the distance D1 from the tip of the gripping portion 222d of the first gripping member 220a to the tip of the gripping portion 221d of the second gripping member 220b is slightly narrower than the opening width W1 of the C-section steel material Csm.

[0121] In this state, when the mounting fixture 200 is placed on the surface of the C-shaped steel material Csm on which the opening is formed, the gripping portions 221d, 222d of the first gripping member 220a and the second gripping member 220b of the mounting fixture 200 pass through the opening of the C-shaped steel material Csm and enter the inside of the C-shaped steel material Csm, so that the base member 230 is placed on the C-shaped steel material Csm with the base member 230 in contact with the end of the C-shaped steel material Csm (see Figures 24 and 25).

[0122] Next, with the mounting fixture 20 placed on the C-shaped steel material Csm, the first gripping member 220a and the second gripping member 220b are fastened to the base member 230 with a second fastening force (final fastening force) by the fastening means 240a and 240b.

[0123] 26 is a diagram illustrating a state in which the first gripping member 220a and the second gripping member 220b of the mounting fixture 200 shown in FIG. 15 have passed the stoppers due to fastening by the first fastening means 240a and the second fastening means 240b, where FIG. 26(a) is a cross-sectional view and FIG. 26(b) is a bottom view showing the mounting fixture 200 in FIG. 26(a) as viewed from the backside. FIG. 27 is a diagram illustrating a state in which the mounting fixture 200 shown in FIG. 18 has been fixed to the C-shaped steel member Csm, where FIG. 27(a) is a cross-sectional view and FIG. 27(b) is a bottom view showing the mounting fixture 200 in FIG. 27(a) as viewed from the backside. Note that the main body member 210 of the mounting fixture 200 is omitted in FIGS. 26 and 27, and the C-shaped steel member Csm in FIG. 27(a) is also omitted in FIG. 27(b).

[0124] Next, with the mounting fixture 200 placed on the C-shaped steel material Csm, the fastening nuts 242a, 242b are tightened to the fastening bolts 241a, 241b with a second fastening force (final fastening force) greater than the first fastening force, and as shown in Figures 26(a) and (b), the first gripping member 220a and the second gripping member 220b disengage from the engaging protrusions 233b, 234b of the base member 230, and the first gripping member 220a and the second gripping member 220b move in the opposite direction so as to move away from each other.

[0125] If the tightening of the fastening nut 241b continues, the first gripping member 220a approaches one of the gripping fastening walls 231 of the base member 230, and the gripping portions 222b and 223b of the first gripping member 220a become caught on and come into contact with one end of the C-shaped steel material Csm, as shown in Figures 27(a) and (b).

[0126] Furthermore, if the tightening of the fastening nut 242b continues, as shown in Figures 27(a) and (b), the second gripping member 220b approaches the other gripping fastening wall 232 of the base member 230, and the gripping portions 222b and 223b of the second gripping member 220b catch on and come into contact with the other end of the C-shaped steel material Csm.

[0127] In this case, the fastening direction in which the first gripping member 220a is fastened to the base member 230 by the fastening bolt 141a and the fastening nut 142a, and the fastening direction in which the second gripping member 220b is fastened to the base member 230 by the fastening bolt 141b and the fastening nut 142b, are substantially perpendicular to the thickness direction X of the constituent members of the gripping portions 222 of the gripping members 220a and 220b, and therefore the gripping portions 222 of the gripping members 220a and 220b can withstand a large tightening force.

[0128] Furthermore, in the mounting device 200 of this second embodiment, the base member 230 has the function of preventing the main body member 210 from rotating around the axis of the connecting bolt 251 relative to the base member 230 .

[0129] Figure 28 is a diagram for explaining the mechanism by which relative rotation of the main body member 210 with respect to the base member 230 is prevented in the mounting device 200 shown in Figure 15, where Figures 28(a) and 28(b) are an oblique view and a side view showing the positional relationship of the main body member 210 with respect to the base member 230, and Figures 28(c) to 28(e) show how the above-mentioned relative rotation is prevented.

[0130] In addition, in this mounting device 200, as shown in Figure 28, engaging protrusions 233b, 2334b are formed on both side portions of the connecting bolt holes 233a, 234a of the main body connecting walls 233, 234 of the base member 230 at intervals corresponding to the width of the first vertical piece 211 and the second vertical piece 212 of the main body member 210.When the front vertical piece 211 and the rear vertical piece 212 of the main body member 210 are connected to the main body connecting walls 233, 234 of the base member 230 (Figures 28(a) and (b)), these engaging protrusions 233b, 2334b abut against both side edges of the front vertical piece 211 and the rear vertical piece 212, as shown in Figure 28(c), thereby preventing the main body member 210 from rotating around the axis of the connecting bolt 251 relative to the base member 230, as shown in Figures 28(d) and (e).

[0131] Furthermore, the mounting fixture 200 of this embodiment 2 has a structure in which the main body member 210, the base member 230, and the two gripping members 220a, 220b are connected with bolts, so similar to the mounting fixture 100 of embodiment 1, the size of the mounting fixture 200 can be flexibly changed to suit the height of the roof material, the size of the C-shaped steel material Csm, etc.
