Description

[Technical Field]

[0001] The present disclosure relates to a fastener for fastening a member to an angle member. [Background technology]

[0002] Conventionally, when fixing a member to be fixed to an L-shaped angle bar extending in the vertical direction, a fixing bracket as disclosed in, for example, Patent Document 1 has been used. The fixing bracket of Patent Document 1 includes a pair of clamping pieces for clamping a ground wire, a plate for fixing the clamping pieces to the angle bar, a fixing bolt, and a nut. The pair of clamping pieces are fixed to the plate by the fixing bolt. The tip of the fixing bolt is provided with a hook portion. With the hook portion hooked onto the end of one plate portion of the angle bar, the plate is brought into contact with the other plate portion, and the nut is tightened, so that the angle bar can be clamped between the plate and the hook portion. In addition to the fixing bolt, the fixing bracket of Patent Document 1 also includes a clamping bolt for tightening the pair of clamping pieces in a closing direction to clamp the ground wire.

[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 59-8221 Summary of the Invention [Problem to be solved by the invention]

[0004] The fixture disclosed in Patent Document 1 includes a pair of clamping pieces, one of which contacts the ground wire from one radial direction and the other from the other radial direction, to clamp the ground wire in the radial direction, as well as a clamping bolt for fastening the pair of clamping pieces in a closing direction. Furthermore, plates, fixing bolts, and nuts are also required to secure the pair of clamping pieces to the angle bar, increasing the number of parts that make up the fixture. As a result, the cost of the fixture increases.

[0005] The present disclosure has been made in consideration of the above points, and an object thereof is to reduce the number of parts and lower costs when fixing a fixed member to an angle iron. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, one aspect of the present disclosure can be based on a fixing bracket for fixing a member to be fixed to an angle bar that has a first plate portion and a second plate portion that are integrated at right angles to each other and extends in the vertical direction.

[0007] The fixing metal fitting is arranged along the side surface of the first plate portion of the angle iron and includes an attachment member that engages with an end of the first plate portion, an engagement member that engages with an end of the second plate portion, and a connecting bolt that connects the attachment member and the engagement member along the side surface of the second plate portion and clamps the angle iron when tightened. The attachment member extends horizontally from the first plate portion of the angle iron and includes a fixing bolt that fixes the fixed member to the attachment member.

[0008] With this configuration, by tightening the connecting bolt connected to the mounting member and the engaging member, the mounting member and the engaging member are fastened in a direction that brings them closer to each other, so that the mounting member and the engaging member clamp the angle bar, and as a result, the fixing bracket is fixed to the angle bar. When fixing a fixed member to the angle bar, rather than clamping the fixed member with a pair of clamp pieces as in conventional examples, the fixed member can be fixed to the mounting member with the fixing bolt, thereby reducing the number of parts.

[0009] The mounting member may also include a clamping member that is inserted onto the fixing bolt and clamps the fixed member between the fixing bolt and the side surface of the first plate portion of the angle iron by tightening the fixing bolt or a fixing nut that screws onto the fixing bolt.

[0010] With this configuration, by tightening the fixing bolt or the fixing nut that screws onto the fixing bolt, the fixed member is clamped between the clamping member and the side surface of the first plate portion of the angle iron and fixed to the angle iron. In other words, instead of clamping the fixed member with a pair of clamp pieces as in conventional examples, the first plate portion of the angle iron can be used to clamp the fixed member between the side surface of the first plate portion and the clamping member, thereby reducing the number of parts.

[0011] The mounting member may have a vertical plate portion extending in the width direction and up and down direction of the first plate portion of the angle iron, and an upper plate portion extending horizontally from the upper edge of the vertical plate portion and on which the fixed member is placed.

[0012] With this configuration, the member to be fixed can be temporarily placed on the upper plate of the mounting member before being fixed to the angle bar. By temporarily placing the member to be fixed, the member can be temporarily positioned at the fixed position, and after the temporary positioning, the member to be fixed can be fixed at the desired position relative to the angle bar.

[0013] The clamping member may have an upper protruding portion that protrudes above the mounting member, in which case the member to be fixed can be clamped between the upper protruding portion and a side surface of the first plate portion of the angle iron.

[0014] The mounting member may have a support portion that supports the fixed member placed on the upper plate portion from the opposite side to the angle iron. This allows the fixed member to be supported by the support portion while temporarily placed on the upper plate portion of the mounting member, thereby preventing the fixed member from tipping over.

[0015] The clamping member may have a lower protrusion that protrudes downward from the mounting member. In this case, the clamping member can be stabilized by fitting a fitting portion formed between the upper protrusion and the lower protrusion of the clamping member into the mounting member. [Effects of the Invention]

[0016] As described above, when a member to be fixed is fixed to an angle bar, the number of parts can be reduced, thereby reducing costs. [Brief explanation of the drawings]

[0018] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that the following description of the preferred embodiments is merely exemplary in nature and is not intended to limit the present invention, its applications, or its uses.

[0019] (Embodiment 1) 1 is a perspective view showing a state in which a fixing bracket 1 according to a first embodiment of the present invention is in use. In this first embodiment, a case will be described in which a fixing bracket 1 is used to fix a second angle member (fixed member) 200 extending horizontally to a first angle member 100 extending vertically, but the fixed member does not have to be the second angle member 200; for example, the fixed member can be a plate material (such as a flat bar), a rod material (such as a reinforcing bar), a square timber, a pipe, a piping, a wire material, or various other members (such as a channel rail).

[0020] The first angle iron 100 has a first plate portion 101 and a second plate portion 102 that are integrated and perpendicular to each other. The first angle iron 100 can also be called an L-shaped angle iron because the first plate portion 101 and the second plate portion 102 form an L shape in a plan view. The material of the first angle iron 100 is not particularly limited, but examples include steel.

[0021] In each figure, the width direction of the first plate portion 101 of the first angle member 100 is used as the reference, and this width direction is defined as the "width direction" of the fixing bracket 1. This defines one width side and the other width side of the fixing bracket 1. Furthermore, the depth direction of the first angle member 100 is defined as the direction perpendicular to the width direction in a plan view, and this depth direction is defined as the "depth direction" of the fixing bracket 1. The depth direction of the first angle member 100 corresponds to the width direction of the second plate portion 102 of the first angle member 100. This definition of direction is provided for convenience in explaining the embodiments and does not limit the present invention; for example, the depth direction may be called the front-to-rear direction.

[0022] Similarly to the first angle member 100, the second angle member 200 has a first plate portion 201 and a second plate portion 202 which are integrated and form a right angle with each other. The second angle member 200 is fixed to the first angle member 100 with the first plate portion 201 of the second angle member 200 positioned in a position extending along the side of the first plate portion 101 of the first angle member 100. The second plate portion 202 of the second angle member 200 fixed to the first angle member 100 is positioned so as to protrude towards the front.

[0023] 2 to 6, the fixing bracket 1 includes a mounting member 10, an engaging member 20, a connecting bolt 30, a connecting nut 40, a fixing bolt 50, a fixing nut 60, and a clamping member 70. The mounting member 10, the engaging member 20, and the clamping member 70 are members formed by press-forming, for example, steel plate or the like.

[0024] As shown in Figure 4, the mounting member 10 is a member that extends in the width direction of the first plate portion 101 of the first angle member 100 along the side surface of the first plate portion 101, and has a horizontally elongated shape with the width dimension being longer than the vertical dimension. One widthwise side portion of the mounting member 10 protrudes toward one widthwise side from the side of the second plate portion 102 of the first angle member 100. In addition, the other widthwise side portion of the mounting member 10 protrudes toward the other widthwise side from the side of the first angle member 100 opposite the second plate portion 102.

[0025] 3 and 6, the mounting member 10 has a vertical plate portion 11 extending in the width direction and up and down direction of the fixing bracket 1, an upper plate portion 12 extending from the upper edge of the vertical plate portion 11 toward the rear side (in the direction approaching the side surface of the first plate portion 101 of the first angle iron 100), and a lower plate portion 13 extending from the lower edge of the vertical plate portion 11 toward the rear side. The vertical plate portion 11, upper plate portion 12 and lower plate portion 13 are integrally molded.

[0026] As shown in Figure 4, the rear edges of the upper plate portion 12 and the lower plate portion 13 are formed to fit along the side surface of the first plate portion 101 of the first angle member 100. As shown in Figure 1, the end (lower end) of the first plate portion 201 of the second angle member 200 can be placed on the upper surface of the upper plate portion 12. By placing the end of the first plate portion 201 of the second angle member 200 on the upper surface of the upper plate portion 12, the second angle member 200 can be temporarily positioned in a fixed position before being fixed to the first angle member 100.

[0027] Because the mounting member 10 has an upper plate portion 12 and a lower plate portion 13 that extend toward the rear, the rear edge portions of the upper plate portion 12 and the lower plate portion 13 abut against the side surface of the first plate portion 101 of the first angle iron 100. With the rear edge portions of the upper plate portion 12 and the lower plate portion 13 abutting against the side surface of the first plate portion 101 of the first angle iron 100, the vertical plate portion 11 is positioned away from the side surface of the first plate portion 101 toward the front. Therefore, a gap S (shown by a dashed line in FIG. 4) is formed between the vertical plate portion 11 and the side surface of the first plate portion 101, with the upper plate portion 12 positioned above this gap S and the lower plate portion 13 positioned below the gap S.

[0028] A first bolt insertion hole 11a (see FIG. 7) is formed in a portion of the vertical plate portion 11 that protrudes from the first angle member 100 in the width direction of the first plate portion 101. Furthermore, a second bolt insertion hole 11b is formed in a portion of the vertical plate portion 11 that corresponds to the side surface of the first plate portion 101 of the first angle member 100. The portion that corresponds to the side surface of the first plate portion 101 is a portion of the vertical plate portion 11 that covers the side surface of the first plate portion 101, and corresponds to the middle portion of the vertical plate portion 11 in the width direction. Both the first bolt insertion hole 11a and the second bolt insertion hole 11b are circular.

[0029] 3 and 4, an upper hook portion 12a is provided at the other end in the width direction of the upper plate portion 12. The upper hook portion 12a protrudes toward the back side and is open on one side in the width direction, and is formed so as to hook onto the end of the first plate portion 101 of the first angle member 100. A lower hook portion 13a is provided at the other end in the width direction of the lower plate portion 13. Like the upper hook portion 12a, the lower hook portion 13a protrudes toward the back side and is open on one side in the width direction, and is formed so as to hook onto the end of the first plate portion 101 of the first angle member 100.

[0030] The vertical plate portion 11 has an extending plate portion 11c that extends further toward one side in the width direction than the upper plate portion 12 and the lower plate portion 13. The extending plate portion 11c is formed with an upper protrusion 11d that extends above the upper surface of the upper plate portion 12. The upper protrusion 11d is positioned away from the side surface of the first plate portion 101 of the first angle member 100 toward the front. Therefore, when the first plate portion 201 of the second angle member 200 is placed on the upper surface of the upper plate portion 12, the first plate portion 201 of the second angle member 200 can be supported by the upper protrusion 11d from the side opposite the first angle member 100, preventing the second angle member 200 from tipping toward the front. In other words, the upper protrusion 11d serves as a support portion that supports the second angle member 200 placed on the upper plate portion 12 from the side opposite the first angle member 100, and also as a fall prevention portion that prevents the second angle member 200 from tipping toward the front. Further, the extending plate portion 11c is formed with a lower protrusion 11e that extends below the lower surface of the lower plate portion 13.

[0031] As shown in Figure 5 and other figures, two protrusions 11f are formed on one widthwise side of the vertical plate portion 11 so as to protrude toward the user. The protrusions 11f are spaced apart in the widthwise direction and are positioned so as to sandwich the first bolt insertion hole 11a from both sides in the widthwise direction. In this embodiment, the connecting bolt 30 inserted into the first bolt insertion hole 11a is a hexagonal bolt, and the head 30a of the connecting bolt 30 is shaped like a hexagonal column, with six flat surfaces formed on the outer periphery of the head 30a. The protrusions 11f abut against the flat surfaces formed on the outer periphery of the head 30a of the connecting bolt 30 inserted into the first bolt insertion hole 11a, thereby preventing the connecting bolt 30 from rotating.

[0032] As shown in FIGS. 1 and 4, the engaging member 20 is a member that engages with the end of the second plate portion 102 of the first angle iron 100. Specifically, the engaging member 20 is plate-shaped and has a third bolt insertion hole 20a corresponding to the first bolt insertion hole 11a. The third bolt insertion hole 20a is circular, just like the first bolt insertion hole 11a. When viewed in the depth direction, the third bolt insertion hole 20a of the engaging member 20 and the first bolt insertion hole 11a of the mounting member 10 are positioned concentrically. The other widthwise side of the engaging member 20 has a bent portion 21 that bends toward the front. The end of the second plate portion 102 of the first angle iron 100 abuts and engages with the front surface of the bent portion 21.

[0033] The connecting bolt 30 is a bolt that connects the mounting member 10 and the engaging member 20 along the side surface of the second plate portion 102 of the first angle iron 100, and clamps the first angle iron 100 when tightened. The shank 30b of the connecting bolt 30 is inserted into the first bolt insertion hole 11a of the mounting member 10 and the third bolt insertion hole 20a of the engaging member 20. The connecting bolt 30 is inserted from the front side to the back side, so that the head 30a of the connecting bolt 30 abuts against the front surface of the vertical plate portion 11 of the mounting member 10. A connecting nut 40 is threadedly engaged with the shank 30b of the connecting bolt 30. The connecting nut 40 abuts against the back surface of the engaging member 20.

[0034] The clamping member 70 is a member for clamping the first plate portion 201 of the second angle member 200 between itself and the side surface of the first plate portion 101 of the first angle member 100 in the thickness direction, and can also be called a pressing member because it is a member that presses down the first plate portion 201 of the second angle member 200. The clamping member 70 has a vertically elongated shape that is long in the up-down direction, and when viewed from the front side, the longitudinal direction of the clamping member 70 and the longitudinal direction of the mounting member 10 are perpendicular to each other. The upper portion of the clamping member 70 has an upper protrusion 71 that protrudes above the top surface of the mounting member 10. The first plate portion 201 of the second angle member 200 is positioned between the upper protrusion 71 and the side surface of the first plate portion 101 of the first angle member 100. The first plate portion 201 of the second angle member 200 is positioned between the upper protrusion 71 and the side surface of the first plate portion 101 of the first angle member 100, and is clamped between the upper protrusion 71 and the side surface of the first plate portion 101 of the first angle member 100.

[0035] The lower portion of the clamping member 70 has a lower protruding portion 72 that protrudes downward below the lower surface of the mounting member 10. The lower protruding portion 72 is configured to abut against the side surface of the first plate portion 101 of the first angle iron 100 below the mounting member 10.

[0036] The clamping member 70 has a main body plate portion 73 that extends in the vertical direction and the width direction of the fixing bracket 1, a first side plate portion 74 that extends from one edge of the main body plate portion 73 in the width direction toward the rear, and an second side plate portion 75 that extends from the edge of the other edge of the main body plate portion 73 in the width direction toward the rear. The main body plate portion 73, the first side plate portion 74, and the second side plate portion 75 are integrally molded. A circular fourth bolt insertion hole 73a, through which the shank 50b of the fixing bolt 50 is inserted, is formed in the vertical middle portion of the main body plate portion 73. When viewed in the depth direction, the fourth bolt insertion hole 73a and the second bolt insertion hole 11b are positioned concentrically.

[0037] The portions of the one side plate portion 74 and the other side plate portion 75 that form the upper protrusion 71 are formed so that the further upward they go, the further back they are located. Therefore, only the upper sides of the portions of the one side plate portion 74 and the other side plate portion 75 that form the upper protrusion 71 come into contact with the first plate portion 201 of the second angle iron 200.

[0038] Furthermore, the portions of the one side plate portion 74 and the other side plate portion 75 that form the lower protrusion 72 are formed to be positioned further back as they go downward. Therefore, only the lower sides of the portions of the one side plate portion 74 and the other side plate portion 75 that form the lower protrusion 72 come into contact with the side surface of the first plate portion 101 of the first angle iron 100.

[0039] Fitting portions 74a, 75a that fit into the mounting member 10 are formed between the upper protrusion 71 and the lower protrusion 72 of the clamping member 70. That is, a notch shaped to fit into the mounting member 10 is formed in the vertical middle portion of one side plate portion 74 so as to open toward the back, and this notch constitutes the fitting portion 74a. In addition, a notch shaped to fit into the mounting member 10 is also formed in the vertical middle portion of the other side plate portion 75 so as to open toward the back, and this notch constitutes the fitting portion 75a. By fitting the fitting portions 74a, 75a of the clamping member 70 into the mounting member 10, the clamping member 70 can be stabilized.

[0040] As shown in FIG. 6 , the fixing bolt 50 is inserted through the second bolt insertion hole 11b and the fourth bolt insertion hole 73a from the first plate portion 101 side of the first angle member 100. Like the connecting bolt 30, the fixing bolt 50 is a hexagonal bolt, and the head 50a of the fixing bolt 50 is shaped like a hexagonal column, with six flat surfaces formed on the outer circumferential surface of the head 50a. Of the six flat surfaces formed on the outer circumferential surface of the head 50a of the fixing bolt 50, the upper flat surface abuts against the underside of the upper plate portion 12, and the lower flat surface abuts against the upper surface of the lower plate portion 13. This makes it possible to prevent the fixing bolt 50 from rotating together when the fixing nut 60 is screwed onto the fixing bolt 50 and tightened.

[0041] The fixing nut 60 is screwed onto the shank 50b of the fixing bolt 50 from the front side. The fixing nut 60 screwed onto the shank 50b of the fixing bolt 50 abuts against the main body plate portion 73 of the clamping member 70 from the front side. This causes the clamping member 70 to be directly fastened to the mounting member 10.

[0042] (Fixing method) Next, a method for fixing the second angle member 200 to the first angle member 100 using the fixing bracket 1 configured as described above will be described. First, as shown in FIG. 4, the fixing bracket 1 is fixed to the first angle member 100. Before fixing the fixing bracket 1 to the first angle member 100, the shank 30b of the connecting bolt 30 is inserted into the first bolt insertion hole 11a of the mounting member 10 and the third bolt insertion hole 20a of the engaging member 20, and a connecting nut 40 is screwed onto the shank 30b to temporarily assemble the mounting member 10 and the engaging member 20. The shank 50b of the fixing bolt 50 is also inserted into the second bolt insertion hole 11b and the fourth bolt insertion hole 73a, and a fixing nut 60 is screwed onto the shank 50b to temporarily assemble the mounting member 10 and the clamping member 70. This allows all of the components that make up the fixing bracket 1 to be integrated, preventing any of the components from falling off.

[0043] Then, the rear edge portions of the upper plate portion 12 and the lower plate portion 13 of the mounting member 10 are brought into contact with the side surfaces of the first plate portion 101 of the first angle iron 100, and the upper hook portion 12a and the lower hook portion 13a are hooked onto and engaged with the ends of the first plate portion 101 of the first angle iron 100. In addition, the bent portion 21 of the engaging member 20 is brought into contact with the end of the second plate portion 102 of the first angle iron 100.

[0044] Thereafter, by tightening the connecting bolt 30 and connecting nut 40, the mounting member 10 and the engaging member 20 are fastened in a direction that brings them closer to each other, and the first angle member 100 is clamped in the depth direction by the mounting member 10 and the engaging member 20, as a result, the fixing bracket 1 is fixed to the first angle member 100. In addition, the upper hook portion 12a and the lower hook portion 13a make strong contact with the end of the first plate portion 101 of the first angle member 100, making it less likely that slippage will occur.

[0045] In this way, the fixing bracket 1 can be fastened and fixed to the desired position on the first angle iron 100 without welding, eliminating the need for welding equipment or welding workers and improving the ease of installation of the fixing bracket 1. Furthermore, if it is desired to change the installation height of the fixing bracket 1, for example, the height can be easily changed by loosening the connecting nut 40, positioning the fixing bracket 1 at the desired height, and then tightening the connecting nut 40. At this point, the fixing nut 60 threaded onto the fixing bolt 50 should be left loose.

[0046] Next, the first plate portion 201 of the second angle member 200 is inserted between the first plate portion 101 of the first angle member 100 and the upper protrusion 11d of the mounting member 10, and between the first plate portion 101 of the first angle member 100 and the upper protrusion 71 of the clamping member 70. Then, the lower end of the first plate portion 201 of the second angle member 200 is placed on the upper surface of the upper plate portion 12 of the mounting member 10. This allows the second angle member 200 to be temporarily positioned in a fixed position, making installation easier. Once temporarily positioned, the first plate portion 201 of the second angle member 200 is supported by the upper protrusion 11d, preventing the second angle member 200 from tipping forward.

[0047] After positioning the second angle member 200, the fixing nut 60 threaded onto the fixing bolt 50 is tightened. This tightens the clamping member 70 in a direction approaching the first plate portion 101 of the first angle member 100, so that the second angle member 200 is clamped between the clamping member 70 and the side surface of the first plate portion 101 of the first angle member 100 and fixed to the first angle member 100. In other words, rather than clamping the member to be fixed with a pair of clamp pieces as in the conventional example, the first plate portion 101 of the first angle member 101 can be used to clamp the second angle member 200 between the side surface of the first plate portion 101 and the clamping member 70, thereby reducing the number of parts.

[0048] Furthermore, when the fixing nut 60 is tightened, the lower protrusion 72 of the clamping member 70 comes into contact with the side surface of the first plate portion 101 of the first angle member 100. In other words, not only the mounting member 10 but also the lower protrusion 72 of the clamping member 70 comes into contact with the side surface of the first plate portion 101 of the first angle member 100, so the fixing strength of the fixing bracket 1 to the first angle member 100 is high and slippage is less likely to occur. This means that the fixing bracket 1 can be fixed at the correct height.

[0049] (Modification of the first embodiment) FIG. 8 shows a fixture 1 according to a first variation of the first embodiment. In this first variation of the first embodiment, the member to be fixed is a round bar 300, and the fixture is configured so that the round bar 300 can be fixed to a first angle member 100. Specifically, one side plate 74 of the clamping member 70 has a notch 74b that opens toward the rear, and the other side plate 75 has a notch 75b that also opens toward the rear. The edges of the notches 74b and 75b are curved in an arc. When the round bar 300 is inserted between the first plate 101 of the first angle member 100 and the upper protrusion 71 of the clamping member 70, it can be placed on the upper surface of the upper plate 12 of the mounting member 10. In this state, the upper protrusion 71 prevents the round bar 300 from falling off.

[0050] Thereafter, when the fixing nut 60 threaded onto the fixing bolt 50 is tightened, the arc-shaped curved portions at the edges of the notches 74b and 75b come into contact with the outer peripheral surface of the round bar 300, and the round bar 300 is fixed to the first angle member 100.

[0051] 9 shows a fixing fixture 1 according to a second modification of the first embodiment. In this second modification of the first embodiment, the extending plate portion 11c, the upper protrusion 11d, and the lower protrusion 11e of the mounting member 10 are omitted. Even if the extending plate portion 11c, the upper protrusion 11d, and the lower protrusion 11e are omitted, the member to be fixed can be fixed to the first angle iron 100 by the clamping member 70. Alternatively, only the lower protrusion 11e may be omitted.

[0052] (Embodiment 2) 10 shows a fastening fixture 1 according to a second embodiment of the present invention. This second embodiment differs from the first embodiment in that the clamping member 70 is omitted, and the upper protrusion 11d and lower protrusion 11e of the mounting member 10 are also omitted. Other parts are the same as those of the first embodiment, and therefore, hereinafter, the same parts as those of the first embodiment will be assigned the same reference numerals and their description will be omitted.

[0053] Because the clamping member 70 is omitted, the member to be fixed is fixed directly to the mounting member 10 by the fixing bolt 50 and the fixing nut 60. For example, an insertion hole for the fixing bolt 50 to pass through is formed in the member to be fixed, and the fixing bolt 50 is then inserted into the insertion hole in the member to be fixed, and the fixing nut 60 is then screwed onto the fixing bolt 50 and tightened. As a result, rather than clamping the member to be fixed between a pair of clamp pieces as in the conventional example, the member to be fixed is fastened to the mounting member 10 and then fixed to the first angle iron 100 via the fixing bracket 1, thereby reducing the number of parts.

[0054] 11 shows a fastening device 1 according to a first modification of the second embodiment. In this first modification of the second embodiment, the first bolt insertion hole 11a and the protrusion 11f are omitted. The head (one end) of the connecting bolt 30 is fixed by welding to the rear surface of the vertical plate portion 11 (the portion protruding in the width direction of the first plate portion 101) of the mounting member 10. In this example, the head of the connecting bolt 30 does not protrude from the front surface of the vertical plate portion 11 of the mounting member 10. Therefore, as shown in FIG. 12, for example, the side plate portion 401 of the channel rail 400 serving as the fixed member can be fastened and fixed with the fastening bolt 50 and the fastening nut 60 in a state where the side plate portion 401 is in contact with the front surface of the vertical plate portion 11.

[0055] As shown in FIG. 13, the first plate portion 201 of the second angle member 200 can be abutted against the front surface of the vertical plate portion 11 and then fastened and fixed using a fixing bolt 50 and a fixing nut 60.

[0056] (Embodiment 3) FIG. 14 shows a fixing bracket 1 according to a third embodiment of the present invention. The same components as those in the first embodiment are designated by the same reference numerals, and their descriptions are omitted. In this third embodiment, the connecting nut 40 is omitted to reduce the number of components. The head 30a of the connecting bolt 30 is positioned on the engaging member 20 side. Furthermore, the vertical plate 11 of the mounting member 10 is burred to form a burred portion 11h. A thread is formed on the inner circumferential surface of the burred portion 11h, into which the shank 30b of the connecting bolt 30 is threadedly engaged. The burred portion 11h has an annular shape that protrudes in the same direction as the upper plate 12 and the lower plate 13. In this third embodiment, the fixing bracket 1 can be secured to the first angle member 100 by tightening the connecting bolt 30.

[0057] (Embodiment 4) Figure 15 shows a fixing bracket 1 according to a fourth embodiment of the present invention. The same parts as in the first embodiment are designated by the same reference numerals, and their explanations will be omitted. In this fourth embodiment, the number of parts is reduced by omitting the connecting nut 40, and the engaging member 20 is provided with a burred portion 20b by burring. A thread groove is formed on the inner peripheral surface of the burred portion 20b, into which the shank 30b of the connecting bolt 30 is threadedly engaged. The burred portion 20b has an annular shape that protrudes in a direction approaching the mounting member 10. In this fourth embodiment, the fixing bracket 1 can be fixed to the first angle member 100 by tightening the connecting bolt 30.

[0058] (Embodiment 5) Figure 16 shows a fixing bracket 1 according to a fifth embodiment of the present invention. The same parts as in the first embodiment are given the same reference numerals, and their explanations will be omitted. In this fifth embodiment, the second bolt insertion hole 11b and the head 50a of the fixing bolt 50 are omitted, and the end of the shank 50b of the fixing bolt 50 is fixed to the vertical plate portion 11 of the mounting member 10 by welding. This eliminates the need to form the second bolt insertion hole 11b in the vertical plate portion 11. Furthermore, the fixing bolt 50 can be prevented from rotating without relying on the head 50a.

[0059] (Embodiment 6) Figure 17 shows a fixing bracket 1 according to a sixth embodiment of the present invention. Parts that are the same as those in the first embodiment are given the same reference numerals and their explanations will be omitted. In this sixth embodiment, the number of parts is reduced by omitting the fixing nut 60, and a burred portion 11i is provided by burring the vertical plate portion 11 of the mounting member 10. A thread is formed on the inner peripheral surface of the burred portion 11i and the shank 50b of the fixing bolt 50 is screwed onto the inner surface from the outside. By tightening the fixing bolt 50, the second angle iron 200 can be fixed by a clamping member 70 (not shown).

[0060] The above-described embodiments are merely examples in all respects and should not be interpreted as limiting. Furthermore, all modifications and variations within the scope of the claims are within the scope of the present invention. Furthermore, the above-described embodiments can be combined with each other.

[0061] Furthermore, the fixing bracket 1 according to this embodiment has a vertically symmetrical shape, and various fixed members can be placed on and fixed to the angle iron regardless of the vertical orientation of the fixing bracket 1. For example, when attaching the fixing bracket 1 to angle irons that are in a parallel position, the fixing bracket 1 can be attached regardless of the orientation of the angle irons. However, this is not limited to this, and the fixing bracket 1 may also have a vertically asymmetrical shape. [Industrial Applicability]

[0062] As described above, the fastening fixture according to the present disclosure can be used to fasten various fastened members to angle members. [Explanation of symbols]
