Description

Technical Field

[0001] The present disclosure relates to a connection structure. More specifically, the present disclosure relates to a connection structure used when connecting a plurality of members.

Background Art

[0002] Patent Document 1 describes a steel structure connecting fitting for vertically butting and connecting lip channel steels. The steel structure connecting fitting is composed of an L-shaped fitting, a nut, a washer, and a bolt. The L-shaped fitting is formed by bending a rectangular steel plate into an L shape to form a support piece and an insertion piece, drilling bolt holes in both pieces, forming notch portions at both end portions of the bent portion of the steel plate to make the insertion piece insertable into the back surface of the lip portion of the lip channel steel, and projecting a pair of nut-locking cut-up pieces on the back surface of the bolt hole of the insertion piece. The nut is locked to the cut-up piece. The washer is located on the upper surface of the lip portion of the lip channel steel and sandwiches the lip portion between it and the insertion piece. The bolt passes through the bolt hole of the washer and is screwed with the nut of the insertion piece. Then, the lip portion is sandwiched by the washer and the horizontal piece, and the two are tightened with the bolt.

[0003] Patent Document 2 describes a method for fixing a metal member. This method for fixing a metal member comprises a fixing member, a backing plate member, a nut, and a pin. The fixing member comprises a plate-shaped first fixing part that abuts against a first structural steel having a bolt passage through which the bolt is inserted, and a cylindrical first boss portion that is in contact with the surface having a boss hole inside, and a second fixing part that is plate-shaped that abuts against a second structural steel having a bolt passage through which the bolt is inserted, and is integrated at a predetermined angle with one end of the first fixing part. The backing plate member has a through hole for inserting the bolt and abuts against the back surface of the first structural steel or the second structural steel. The nut is screwed onto the bolt at the tip end of the bolt, causing the first or second structural steel to be sandwiched between the backing plate member and the first or second fixing part. The pin is inserted through the boss hole of the first or second boss part, expanding the diameter of the boss hole and penetrating the first or second structural steel.

[0004] Then, with the first or second structural steel sandwiched between the first or second fixing part and the back plate member, the bolt is inserted through the bolt passage and the first or second insertion hole and the nut is screwed on to tighten the fixing member and the back plate member, and the pin is inserted into the boss hole of the first or second boss part, expanding the diameter of the boss hole and passing through the first or second boss part and the first or second structural steel, thereby integrating the fixing member with the first or second structural steel.

Embodiments for Carrying Out the Invention

[0011] Hereinafter, the present disclosure will be described based on the embodiments shown in the accompanying drawings. However, the present disclosure is not limited to the following embodiments, and appropriate design changes can be made within the intended scope of the present disclosure.

[0012] (Embodiment) (1) Overview The connecting structure 100 of the present embodiment includes a connecting member 1, a joining member 2, a fixing plate 3, and a fastener 4 (see FIGS. 17 and 18). The connecting member 1 has a pair of connecting pieces 11. The joining member 2 is disposed on the surface side of the pair of connecting pieces 11. The fixing plate 3 has a plate portion 30. The plate portion 30 is disposed on the back side of the pair of connecting pieces 11. Further, the plate portion 30 is disposed to face the joining member 2. The fastener 4 has a bolt 41 and a nut 42. The bolt 41 is disposed through between the pair of connecting pieces 11 and inserted into the joining member 2 and the plate portion 30. The joining member 2 and the fixing plate 3 are coupled by tightening the bolt 41 and the nut 42. The fixing plate 3 has a rotation prevention piece 35. The rotation prevention piece 35 protrudes from the plate portion 30 and is positioned between the pair of connecting pieces 11.

[0013] According to the present embodiment, the rotation prevention piece 35 of the fixing plate 3 can be tightened with the bolt 41 and the nut 42 while being positioned between the pair of connecting pieces 11 of the connecting member 1. Therefore, the rotation prevention piece 35 hits the pair of connecting pieces 11 and it becomes difficult for the fixing plate 3 to rotate. Thus, when tightening the bolt 41 and the nut 42, it becomes difficult for the fixing plate 3 to rotate in the wrong direction, and it becomes easy to perform the connecting operation of the connecting member 1 and the joining member 2 (a plurality of members). Further, by loosening the tightening of the bolt 41 and the nut 42, the clamping of the pair of connecting pieces 11 by the joining member 2 and the fixing plate 3 can be released, and the position of the joining member 2 with respect to the connecting member 1 can be easily changed without newly forming a bolt hole.

[0014] (2) Details Figure 1 shows the installation structure of a solar panel using the connecting structure 100 of this embodiment. In this installation structure, multiple solar panels 201 are installed on a mounting frame 200. The mounting frame 200 is installed on a base 203 made of H-shaped steel or the like.

[0015] Figure 2 shows a frame 200 using the connecting structure 100 of this embodiment. The frame 200 comprises a plurality of connecting members 1, a plurality of joining members 2, and a plurality of support members 5.

[0016] <Connecting members> The multiple connecting members 1 include multiple first connecting members 101 and multiple second connecting members 102. The connecting members 1 (first connecting members 101 and second connecting members 102) are formed from lip channel steel. That is, the connecting member 1 includes a pair of connecting pieces 11, a base piece 12, and a pair of connecting pieces 13 (see Figures 16 and 17).

[0017] The pair of connecting pieces 11 are made up of the lip portion of the lip channel steel and are arranged vertically with a predetermined interval between them. The pair of connecting pieces 11 are positioned in front of the base piece 12 so as to face the base piece 12. The pair of connecting pieces 11 are also arranged substantially parallel to the base piece 12.

[0018] The pair of connecting pieces 13 are provided almost parallel to each other and facing each other vertically. The upper connecting piece 13 is provided between the upper end of the base piece 12 and the upper connecting piece 11, connecting the base piece 12 and the upper connecting piece 11. The lower connecting piece 13 is provided between the lower end of the base piece 12 and the lower connecting piece 11, connecting the base piece 12 and the lower connecting piece 11.

[0019] The first connecting member 101 and the second connecting member 102 are both lip channel steel, but the first connecting member 101 and the second connecting member 102 may be lip channel steel of the same size or may be lip channel steel of different sizes. In this embodiment, the vertical dimension of the base piece 12 is larger for the first connecting member 101 than for the second connecting member 102. The projection dimension of the connecting piece 13 from the base piece 12 is larger for the first connecting member 101 than for the second connecting member 102. The projection dimension of the connecting piece 11 from the connecting piece 13 is approximately the same for both the first connecting member 101 and the second connecting member 102. The plate thickness of the first connecting member 101 and the second connecting member 102 is also approximately the same.

[0020] In the frame 200 shown in Figure 2, two first connecting members 101 are used. The two first connecting members 101 are each positioned above the base 203. The first connecting members 101 are fixed to the base 203 using leg members 204 and braces 205. The first connecting members 101 are positioned so that their rear end is slightly higher than their front end. Therefore, the first connecting members 101 are positioned so that they slope slightly downward from the rear end to the front end.

[0021] The frame 200 uses four second connecting members 102. The four second connecting members 102 are positioned above the first connecting member 101. The second connecting members 102 rest on the connecting piece 13 above the first connecting member 101. The four second connecting members 102 are arranged to span across two first connecting members 101. In plan view (viewed from above), the first connecting member 101 is formed to extend in one direction, and the second connecting members 102 are formed to extend in a direction perpendicular to that direction. For example, the first connecting member 101 is positioned to extend in the front-to-back direction and is formed as a vertical rail member, and the second connecting member 102 is positioned to extend in the left-to-right direction and is formed as a horizontal rail member.

[0022] <Joining member> Figures 10, 11, and 12 show the joining member 2. The joining member 2 is formed by bending or other processing of a metal plate such as a steel plate. The joining member 2 has a first joining piece 21, a second joining piece 22, and a locking piece 23. The first joining piece 21 and the second joining piece 22 are formed as flat plates extending in the vertical direction. In a plan view (viewed from above), the first joining piece 21 and the second joining piece 22 are connected at one end of their long sides so that they form a roughly L-shape.

[0023] The joining member 2 has a joining hole 20. The first joining piece 21 has a first joining hole 211 that penetrates in the thickness direction as the joining hole 20. The first joining hole 211 is formed in the lower part of the first joining piece 21. The second joining piece 22 has a second joining hole 212 that penetrates in the thickness direction as the joining hole 20. The second joining hole 212 is formed in the upper part of the second joining piece 22.

[0024] The locking piece 23 is flat and, in plan view, is formed in a substantially square shape. One end of the locking piece 23 is connected to the lower end of the first connecting piece 21. Also, in plan view, the locking piece 23 protrudes from the lower end of the first connecting piece 21 on the side opposite to the second connecting piece 22. Therefore, the locking piece 23 is not located below the second connecting piece 22.

[0025] <Fixing plate> In this embodiment, the connecting structure 100 has a fixing plate 3. The fixing plate 3 is formed by bending or other processing of a metal plate such as a steel plate. The fixing plate 3 is used when connecting the connecting member 1 and the joining member 2. The fixing plate 3 has a first fixing plate 31 and a second fixing plate 32. The first fixing plate 31 is used when connecting the first connecting member 101 and the joining member 2. The second fixing plate 32 is used when connecting the second connecting member 102 and the joining member 2.

[0026] Figures 4 and 5 show the first fixing plate 31. Figures 6 and 7 show the second fixing plate 32. The first fixing plate 31 and the second fixing plate 32 differ in size, but their shapes are almost identical.

[0027] The fixing plate 3 (first fixing plate 31 and second fixing plate 32) comprises a plate portion 30 and an anti-rotation piece 35. The plate portion 30 is formed in a flat plate shape. When viewed from the front (from the front) or rear (from the rear), the plate portion 30 has a pair of vertical sides 301, a pair of horizontal sides 302, and a pair of inclined sides 303.

[0028] The pair of vertical sides 301 are formed to be elongated in the vertical direction and aligned horizontally when viewed from the front or back. Each vertical side 301 is provided with one anti-rotation piece 35. The pair of horizontal sides 302 are formed to extend in a direction perpendicular to the vertical sides 301. The pair of horizontal sides 302 are formed to be elongated in the horizontal direction and aligned vertically when viewed from the front or back. The pair of inclined sides 303 are formed between the ends of the vertical sides 301 and the ends of the horizontal sides 302.

[0029] In other words, one of the pair of inclined edges 303 is continuous with the left end of the upper horizontal edge 302 and the upper end of the left vertical edge 301. The other of the pair of inclined edges 303 is continuous with the right end of the lower horizontal edge 302 and the lower end of the right vertical edge 301. The pair of inclined edges 303 can be formed by diagonally cutting off two diagonally opposite corners of a rectangular plate material, as seen from the front or back.

[0030] The pair of anti-rotation pieces 35 are formed to protrude forward (towards the surface side of the plate portion 30) from the plate portion 30. The pair of anti-rotation pieces 35 are formed in a flat plate shape and are formed to extend vertically along the vertical side 301. The position of the upper end of the pair of anti-rotation pieces 35 is below the position of the lower end of the upper inclined side 303 when viewed from the front or rear. Also, the position of the lower end of the pair of anti-rotation pieces 35 is above the position of the upper end of the lower inclined side 303 when viewed from the front or rear.

[0031] The plate portion 30 also has a through hole 304. The through hole 304 is formed to penetrate through the plate portion 30 in the thickness direction, approximately in the center of the plate portion 30.

[0032] The first fixing plate 31 and the second fixing plate 32 are of different sizes. The vertical dimension of the plate portion 30 is larger for the first fixing plate 31 than for the second fixing plate 32. Also, the vertical dimension of the anti-rotation piece 35 is larger for the first fixing plate 31 than for the second fixing plate 32. On the other hand, the distance between the pair of anti-rotation pieces 35 and the protrusion of the pair of anti-rotation pieces 35 from the plate portion 30 are approximately the same for the first fixing plate 31 and the second fixing plate 32.

[0033] <Connection structure> Figure 3 shows the connecting structure 100 of this embodiment. The connecting structure 100 of this embodiment is formed as follows.

[0034] First, as shown in Figure 16, a fixing plate 3 is provided on the connecting member 1. The fixing plate 3 is positioned such that the plate portion 30 is located on the back side (the side facing the base piece 12) of the pair of connecting pieces 11. That is, the plate portion 30 is located between the base piece 12 and the pair of connecting pieces 11, and also between the pair of connecting pieces 13. The pair of anti-rotation pieces 35 of the fixing plate 3 are positioned so as to protrude from between the pair of connecting pieces 11 to the front side (the side facing away from the base piece 12) of the pair of connecting pieces 11. Therefore, the dimension L2 of the anti-rotation piece 35 in the direction perpendicular to the protrusion direction from the plate portion 30 is about 2 to 5 mm smaller than the dimension L1 between the pair of connecting pieces 11.

[0035] When providing the fixing plate 3 to the connecting member 1, the fixing plate 3 can be moved to the desired position on the connecting member 1 by sliding the fixing plate 3 in the longitudinal direction of the connecting member 1 while the plate portion 30 is positioned on the inside of the connecting member 1 (between the base piece 12 and the pair of connecting pieces 11) from the longitudinal end of the connecting member 1.

[0036] Here, if the connecting member 1 is long, it is time-consuming to slide the fixing plate 3 from the longitudinal end of the connecting member 1 to the desired position. Therefore, the fixing plate 3 can be positioned inside the connecting member 1 at or near the desired position where the fixing plate 3 will be installed. In this case, the fixing plate 3 is inserted inside the connecting member 1 from between the pair of connecting pieces 11, and then rotated or otherwise operated to achieve the desired orientation. For example, as shown in Figure 18, the fixing plate 3 is rotated counterclockwise around the through hole 304 inside the connecting member 1 so that the horizontal side 302 of the plate portion 30 and the pair of connecting pieces 13 are approximately parallel.

[0037] When inserting the fixing plate 3 into the inside of the connecting member 1 from between the pair of connecting pieces 11, it is preferable that the dimension L3 of the anti-rotation piece 35 in the direction of protrusion from the plate portion 30 is formed to be smaller than the dimension L1 between the pair of connecting pieces 11 (see Figure 16). Furthermore, it is preferable that the dimension L35 between the pair of anti-rotation pieces 35, the dimension L36 between the pair of horizontal sides 302, and the dimension LS between the connection portion S between the pair of horizontal sides 302 and the pair of inclined sides 303 are formed to be smaller than the dimension L13 between the pair of connecting pieces 13 (see Figure 19). This allows the fixing plate 3 to be easily rotated inside the connecting member 1. In particular, in this embodiment, since the plate portion 30 is not rectangular but has a shape in which the corners at a pair of diagonal positions are cut off, the plate portion 30 is less likely to come into contact with the inner surface of the pair of connecting pieces 13, making it easier to operate, such as by rotating.

[0038] After placing the fixing plate 3 on the connecting member 1 as described above, the joining member 2 is placed on the connecting member 1 as shown in Figures 17 and 18. At this time, the joining member 2 is placed on the surface side of the pair of connecting pieces 11. The joining member 2 is also placed between the pair of anti-rotation pieces 35 that protrude outward from the connecting member 1. The joining member 2 is also placed opposite the plate portion 30. The joining hole 20 of the joining member 2 is also placed opposite the through hole 304 of the plate portion 30.

[0039] Next, the joining member 2 is fixed to the connecting member 1 using the fastener 4. The fastener 4 has a bolt 41 and a nut 42. The bolt 41 is inserted from the inside of the connecting member 1 into the through hole 304 of the plate portion 30. The bolt 41 inserted into the through hole 304 protrudes from the through hole 304 and is positioned between the pair of connecting pieces 11. Then, the bolt 41 positioned between the pair of connecting pieces 11 is inserted into the joining hole 20 of the joining member 2, and the tip of the bolt 41 protrudes from the joining hole 20. After this, the nut 42 is attached to the tip of the bolt 41.

[0040] By joining the joining member 2 and the fixing plate 3 in this manner by tightening the bolt 41 and nut 42, the pair of connecting pieces 11 can be sandwiched between the upper and lower parts (above and below the anti-rotation piece 35) of the joining member 2 and the fixing plate 3, thereby connecting and fixing the joining member 2 to the connecting member 1.

[0041] Here, if the connecting member 1 is the first connecting member 101, then, as shown in Figure 17, the first fixing plate 31 is used as the fixing plate 3. The first fixing plate 31 is positioned inside the first connecting member 101, and a pair of anti-rotation pieces 35 of the first fixing plate 31 are positioned between a pair of connecting pieces 11 of the first connecting member 101. The plate portion 30 of the first fixing plate 31 is positioned opposite the first joining piece 21 of the joining member 2. The through hole 304 of the plate portion 30 of the first fixing plate 31 and the first joining hole 211, which is the joining hole 20 of the joining member 2, are positioned opposite each other. Then, after inserting the bolt 41 of the first fastener 401, which is the fastener 4, into the through hole 304, between the pair of connecting pieces 11, and into the first joining hole 211, the bolt 41 and the nut 42 of the first fastener 401 are tightened, thereby clamping the pair of connecting pieces 11 of the first connecting member 101 between the first joining piece 21 and the upper and lower parts of the first fixing plate 31 (upper and lower parts than the anti-rotation piece 35), and the lower part of the joining member 2 can be connected to and fixed to the first connecting member 101.

[0042] Furthermore, when the connecting member 1 is the second connecting member 102, as shown in Figure 18, the second fixing plate 32 is used as the fixing plate 3. The second fixing plate 32 is positioned inside the second connecting member 102, and a pair of anti-rotation pieces 35 of the second fixing plate 32 are positioned between a pair of connecting pieces 11 of the second connecting member 102. The plate portion 30 of the second fixing plate 32 is positioned opposite the second joining piece 22 of the joining member 2. The through hole 304 of the plate portion 30 of the second fixing plate 32 and the second joining hole 212, which is the joining hole 20 of the joining member 2, are positioned opposite each other. Then, after inserting the bolt 41 of the second fastener 402, which is the fastener 4, into the through hole 304, between the pair of connecting pieces 11, and into the second joining hole 212, the bolt 41 and the nut 42 of the second fastener 402 are tightened, thereby clamping the pair of connecting pieces 11 of the second connecting member 102 between the second joining piece 22 and the upper and lower parts of the second fixing plate 32 (upper and lower parts than the anti-rotation piece 35), and the upper part of the joining member 2 can be connected to and fixed to the second connecting member 102.

[0043] In this way, the first connecting member 101 and the second connecting member 102 are connected via the first fixing plate 31, the first fastener 401, the joining member 2, the second fixing plate 32, and the second fastener 402. Furthermore, by loosening the tightening of the bolt 41 and nut 42 of the first fastener 401, the clamping of the pair of connecting pieces 11 between the first joining piece 21 and the first fixing plate 31 is released, allowing the joining member 2 to slide in the longitudinal direction of the first connecting member 101, and the position of the joining member 2 relative to the first connecting member 101 can be easily changed. Similarly, by loosening the tightening of the bolt 41 and nut 42 of the second fastener 402, the clamping of the pair of connecting pieces 11 between the second joining piece 22 and the second fixing plate 32 is released, allowing the joining member 2 to slide in the longitudinal direction of the second connecting member 102, and the position of the joining member 2 relative to the second connecting member 102 can be easily changed.

[0044] Furthermore, in the connecting structure 100 of this embodiment, the upper and lower end surfaces of the pair of anti-rotation pieces 35 of the fixing plate 3 come into contact with the pair of connecting pieces 11, making it difficult for them to rotate. When tightening or loosening the bolts 41 and nuts 42, even if the bolts 41 or nuts 42 are rotated, the fixing plate 3 is less likely to rotate along with them. Therefore, the operation of connecting the joining member 2 to the connecting member 1 is made easier.

[0045] The locking piece 23 of the joining member 2 is hooked onto the lower surface of the first connecting member 101 (the outer surface of the lower connecting piece 13). This makes it difficult for the joining member 2 to detach from the first connecting member 101 even if an upward force is applied to it. For example, even if a force is applied that blows the solar panel 201 upward, the joining member 2 will be firmly fixed to the first connecting member 101.

[0046] <Installation of solar panels> The mounting frame 200 shown in Figure 2 is provided with multiple support members 5 for attaching solar panels 201. Each support member 5 comprises a support fixture 51, a support fixture fixing plate 52, and a panel retainer 53.

[0047] Figures 13, 14, and 15 show the support member 51. The support member 51 is an L-shaped angle and has a fixing piece 511 and a mounting piece 512. The fixing piece 511 has a through hole 513 that penetrates in the thickness direction. The mounting piece 512 has a screw hole 514 that penetrates in the thickness direction.

[0048] As shown in Figures 8 and 9, the support fixing plate 52 is formed to be almost identical to the second fixing plate 32. The support fixing plate 52 has larger dimensions for the pair of anti-rotation pieces 35 compared to the second fixing plate 32, but otherwise the support fixing plate 52 is the same as the second fixing plate 32. Therefore, the support fixing plate 52 has a flat plate portion 30, and the plate portion 30 is formed to be flat. In a front view (viewed from the front) or rear view (viewed from the rear), the plate portion 30 has a pair of vertical sides 301, a pair of horizontal sides 302, and a pair of inclined sides 303.

[0049] Each of the pair of vertical sides 301 is provided with one anti-rotation piece 35. The pair of anti-rotation pieces 35 are formed to protrude forward (towards the surface side of the plate portion 30) from the plate portion 30. The plate portion 30 also has a through hole 304. The through hole 304 is formed to penetrate through the plate portion 30 in the thickness direction, approximately in the center of the plate portion 30.

[0050] The support member 5 is then fixed to the second connecting member 102 in the same manner as the joining member 2. That is, the support member 5 is positioned on the surface side of the pair of connecting pieces 11. The support fixing plate is positioned inside the second connecting member 102, and the plate portion 30 is positioned on the back side of the pair of connecting pieces 11 and opposite the fixing piece 511 of the support 51. The through hole 304 of the plate portion 30 and the through hole 513 of the fixing piece 511 are positioned opposite each other.

[0051] Then, the bolt 41 of the fastener 4 is inserted into the through hole 304 and the through hole 513. At this time, the bolt 41 is positioned between the pair of connecting pieces 11 of the second connecting member 102. After this, by tightening the bolt 41 and the nut 42, the fixing piece 511 of the support member 51 and the upper and lower parts of the plate portion 30 of the support member fixing plate 52 (above and below the anti-rotation piece 35) clamp the pair of connecting pieces 11 of the second connecting member 102, thereby fixing the support member 5 to the second connecting member 102.

[0052] The panel retainer 53 is placed on the mounting piece 512 and fixed to the mounting piece 512 with screws 54 that are inserted into screw holes 514 (see Figure 3).

[0053] The support member 5 can slide longitudinally relative to the second connecting member 102 by loosening the tightening of the bolt 41 and nut 42. The solar panel 201 can also be attached to the mounting frame 200 by sandwiching the end of the solar panel 201 between the pressing piece 531 and the mounting piece 512 of the panel holder 53.

[0054] Furthermore, in the support member 5, since the pair of anti-rotation pieces 35 of the support fixing plate 52 are positioned between the pair of connecting pieces 11 of the second connecting member 102, the support fixing plate 52 is less likely to rotate when tightening or loosening the bolts 41 and nuts 42, making it easier to fix the support member 5. In addition, when changing the size or mounting position of the solar panel 201, the solar panel 201 can be installed without adding new bolt holes.

[0055] (modified version) In the above embodiment, a lip channel steel was used as the connecting member 1, but the invention is not limited to this. For example, a pair of connecting pieces may be fixed separately to a steel material such as an H-beam by welding or the like to form the connecting member 1.

[0056] In the above embodiment, the fixing plate is equipped with a pair of anti-rotation pieces, but the invention is not limited to this, and there may be only one anti-rotation piece.

[0057] In the above embodiment, the support is provided on the second connecting member, but the invention is not limited to this; the support may also be provided on the first connecting member, or on both the first and second connecting members.

[0058] Although the above embodiment described a mounting frame for solar panels, it is not limited to this and can be used to connect multiple components that make up a building (for example, columns, beams, rafters, purlins, battens, etc.).

[0059] In the above embodiment, the case in which the connecting member 1 is used with the pair of connecting pieces 11 aligned in the vertical direction was described, but the invention is not limited to this, and the connecting member 1 may also be used with the pair of connecting pieces 11 aligned in the horizontal direction.
