Description

  The present invention relates to an on-roof mounting bracket suitable for fixing an attachment such as a roof plate or an installation on a roof such as a clammed folded plate roof, and more specifically, while being small in size. It relates to a mounting bracket on the roof that can provide high strength.

  As a roof mounting bracket for fixing a folded plate on a folded plate roof, there is one that has been miniaturized as in Patent Document 1 below.

  This metal fitting (hanger support member) is fixed to the ridge part and the top surface of the mountain part of the folded-plate roof, and has a cross-section inverted concave-shaped accommodation part that accommodates the ridge part, and one side of this accommodation part. The main body metal fitting which has a contact part which extends horizontally from and contacts a top surface is provided. A fastening bolt for fastening the collar part is held on the side surface opposite to the contact surface part in the housing part of the main body metal fitting, and a mounting bolt for attaching a hanging hook for fixing the folded plate faces upward on the contact surface part. Is fixed.

  The tip of the tightening bolt presses the overlapping portion below the winding portion at the top of the collar. For this reason, it is not necessary to provide a structure for sandwiching the collar part above the collar part, and the metal fitting can be reduced in size at the time of fixing.

  On the other hand, the load applied from above will be supported by the end face of the metal plate constituting the housing part and the head of the mounting bolt exposed on the lower surface of the contact surface part, and for the force pulled upward, Must be maintained with the clamping bolt pressure. Moreover, when the end surface of a metal plate or the front-end | tip of a volt | bolt hits a folded plate strongly, a folded plate will also be damaged.

  Patent Document 2 discloses a roof mounting bracket for fixing a solar cell module on a folded plate roof.

  This metal fitting has a main metal fitting (lower surface opening concave metal) attached in a state straddling the top or convex portion of the folded plate roof, and a fastening metal fitting (upper surface opening concave metal) connected to one side of the main body metal fitting with a bolt. The main body metal fitting has a crimping piece that is crimped to one side of the top or the convex part of the folded plate, and the fastening metal fitting has a crimping piece that is crimped to the other side of the top part or the convex part. The pair of crimping pieces clamps the top portion or the convex portion in a crimped state by tightening the bolts, thereby fixing the metal fitting to the folded plate roof.

  Even in this metal fitting, the main metal fitting covers the top or convex portion of the folded plate and is fastened and fixed at a position lower than the upper end of the top or convex portion, so that downsizing with a low height can be realized.

  A metal fitting similar to that of Patent Document 2 is also disclosed in Patent Document 3. In any of the metal fittings of Patent Documents 2 and 3, a pair of sandwiching pieces for sandwiching the buttocks and the like of the folded plate roof are provided in a pair of members, and the pair of members are positioned at the height of the buttocks and the like of the folded plate roof. Since the bolts are fastened and fixed, the height at the time of fixing can be kept low. In addition, since it is not directly tightened with bolts, there is an advantage that it is difficult to damage the folded plate.

  The following Patent Documents 4 and 5 are also disclosed as metal fittings for fixing a folded plate with the same configuration as the metal fittings of Patent Documents 2 and 3.

  However, in any of the metal fittings of Patent Documents 2, 3, 4, and 5, since the pair of members having the holding pieces are connected by one bolt, the shear load is concentrated on the bolt. Although the metal fitting of patent document 3 has the top plate material which mutually overlaps on the upper end part of a pair of member so that a slide is possible, the load concerning a volt | bolt is not disperse | distributed effectively.

  An embodiment for carrying out the present invention will be described below with reference to the drawings.

  The roof mounting bracket (hereinafter referred to as “mounting bracket”) according to the present invention is fixed to a roof having a ridge portion between left and right plane portions, and a roof plate as an attachment for repair purposes. It is used to fix or fix installations such as solar panels and snow stoppers as attachments for the purpose of imparting functions.

  A perspective view of an example of the mounting bracket 11 is shown in FIG. As shown in FIGS. 2 and 3, the mounting bracket 11 is attached to the folded plate roof 61 as the lower roof 51 and fixes the folded plate 61 a for the folded roof 61 as the upper roof 52. It is suitable for FIG. 2 shows an example of a round roof folding plate roof 61, and FIG. 3 shows an example of a square roof folding plate roof 61. As shown in these drawings, the mounting bracket 11 is used regardless of the form of the flange portion 61b. be able to.

  In addition to the roof, the above-described folded plate roof 61, which is an example, has a waveform that repeats a mountain portion and a valley portion, on the top surface of the mountain portion, as left and right flat portions 61b and 61c, and a ridge portion sandwiched between them. It has the collar part 61b. Although the plane portions 61b and 61c are drawn horizontally in the illustrated example, some of them may be inclined. The roof may be a folding-type folded-plate roof, a fitting-type folded-plate roof, a tiled rod roof, a vertical flat roof, or the like.

  As shown in FIG. 1, the mounting bracket 11 includes a support body 12 provided so as to straddle the flange portion 61b from one flat surface portion 61c to the other flat surface portion 61d among the flat surface portions 61c and 61d of the folded plate roof 61, The support body 12 is provided with a sandwiching body 13 for attaching a hanger 71, which is a fixing tool for fixing the folded folded plate 61a, and a fastening bolt 14 for connecting them. The support 12 and the sandwiching body 13 are formed by pressing a metal plate.

  As shown in FIG. 4, the support body 12 has a substantially inverted concave shape when viewed from the front, and has a pair of leg portions 21 and 22 that face each other in parallel or substantially in parallel with the flange portion 61 b interposed therebetween. It has the connection part 23 which connects the upper part of 22, and is formed with one strip | belt-shaped metal plate which makes predetermined width. One of the pair of legs 21 and 22 (the left side in the drawing, the upstream side of the folded plate roof 61 in the formation direction) has a bent part 21a that bends inward at the lower end extending downward. Yes. The angle and length of the bent portion 21a are appropriately set according to the structure of other parts.

  Of the pair of leg portions 21 and 22, the other leg portion 22 (on the right side in the drawing, downstream of the folding direction of the folded plate roof 61) is set to be substantially the same height as the one leg portion 21, and the metal plate is folded. Is formed. That is, after extending the metal plate which is a material from the edge of the connection part 23 below, it is folded by predetermined length, extended upwards, and it overlap | superposed. The direction of folding may be inward or outward, but the illustrated example shows an example of folding outward.

  The other leg portion 22 is formed with a screw hole 22a into which the fastening bolt 14 is screwed. The screw hole 22a is formed at an intermediate position in the width direction of the leg portion 22 and a substantially intermediate position in the vertical direction. When the support 12 surrounds the flange portion 61b, the fastening bolt 14 is positioned beside the flange portion 61b. Thus, the height at which the fastening bolt 14 is positioned can be kept low.

  The connecting portion 23 that connects the pair of leg portions 21 and 22 is formed horizontally, and has a step portion 23a at an intermediate portion in the left-right direction. The stepped portion 23a has a height of a portion (low top plate portion 23b) on the downstream side (the right side of the drawing) of the folded plate roof 61 from the stepped portion 23a, and the upstream of the folded plate roof 61 in the formed direction from the stepped portion 23a. It is made slightly lower than the side (left side of the drawing) (high top plate portion 23c). A part of the high top plate part 23 c that is a part of the connecting part 23 is a contact surface part 24 that comes into contact with the sandwiching body 13 from below and comes into surface contact therewith. Reinforcing ribs 25 are formed at the corners between the connecting portion 23 and the left and right leg portions 21 and 22 so as to project inside.

  The sandwiching body 13 is a substantially C-shaped steel shape whose front view has an opening in the lower side, and the upper receiving portion 31 that extends horizontally and the upstream side (left side in the drawing) of the folded plate roof 61 in the receiving portion 31 in the formation direction. A hanging portion 32 extending downward from the end, a fixed-side clamping piece 33 extending horizontally from the lower end of the hanging portion 32, and an obliquely lower end from the downstream side (right side in the drawing) of the folded plate roof 61 in the receiving portion 31. It has a movable part 34 that extends and a movable-side clamping piece 35 formed at the lower end of the movable part 34. Similar to the support body 12, the sandwiching body 13 is formed of a single band-shaped metal plate having a predetermined width. The width of the sandwiching body 13 and the width of the support 12 are the same.

  The receiving portion 31 is a portion to which a fixing tool is attached. Since the fixing tool is the hanging member 71 and is fixed to a flat surface as described above, the step portion 31a is formed at a substantially intermediate position in the left-right direction of the receiving portion 31. Has been. The step portion 31 is a portion (low top plate portion 31b) on the downstream side (right side of the drawing) of the folded plate roof 61 from the step portion 31, and the upstream side (drawing) of the folded plate roof 61 from the step portion 31a. It is made lower than the portion on the left side (the high top plate portion 31c). The low top plate portion 31b is a portion for fixing the hanging piece 71, and a mounting bolt 36, which is a fixing tool for fixing the folded plate 61a, is fixed by caulking toward the tip.

  The length of the mounting bolt 36 is set so that the tip of the mounting bolt 36 is not higher than the height of the receiving portion 31, that is, the height of the high top plate portion 31c.

  The length of the receiving portion 31 in the left-right direction is longer than the length of the support 12 in the left-right direction. Since it fixes to the folded-plate roof 61 which has a mountain part, it is preferable that it is the length of the left-right direction which fits in the top face of a mountain part when it fixes.

  Moreover, a part of the low top plate part 31 b which is a part of the receiving part 31 is a contact surface part 37 which is in surface contact with the support. For this reason, the level difference of the stepped portion 23 a of the support 12 is a height corresponding to the thickness of the head 36 a of the mounting bolt 36 exposed on the lower surface of the receiving portion 31 of the holding body 13.

  The drooping portion 32 is a plate-like one located outside the one leg portion 21 of the support 12, and is formed with a height higher than that of the one leg portion 21.

  The fixed-side clamping piece 33 has an engaging portion 33a that receives and engages with a lower end of one leg portion 21 of the support body 12, specifically, a bent portion 21a, at a tip portion extending inward. Is a pressing surface 33b that is applied to one side of the flange portion 61b, that is, the side surface on the upstream side (left side in the drawing) of the folded plate roof 61 in the flange portion 61b. The front end of the fixed-side clamping piece 33 has an upright piece 33c that bends upward so as to be L-shaped when viewed from the front. The front end of the bent portion 21a at the lower end of the one leg portion 21 of the support 12 abuts against the standing piece 33c, and the above-described engagement state is obtained.

  A series of reinforcing ribs 38 that bulge to the inner surface side are formed on the hanging portion 32 from the step portion 31a of the receiving portion 31 and the portion on the hanging portion 32 side of the solid-side clamping piece 33.

  The movable part 34 is rotationally deformed toward the other leg part 22 of the pair of leg parts 21 and 22 of the support 12, and the height of the step part 31 a is subtracted from the length of the hanging part 32. It is set to length. A through hole 39 is formed at a boundary portion between the movable portion 34 and the receiving portion 31. The through holes 39 are for imparting deformability to rotate the movable portion 34 downward from an oblique posture, and are appropriately formed in an appropriate shape.

  A loose hole 34 a through which the fastening bolt 14 is inserted is formed at an intermediate position in the width direction of the movable portion 34. The loose hole 34a is formed long in the direction in which the movable portion 34 extends. The length of the loose hole 34 a is a length that allows the fastening bolt 14 to be screwed into the screw hole 22 a of the support 12 to allow the movable portion 34 to rotate and deform in a direction in contact with the support 12.

  The movable side clamping piece 35 has an upright piece 35a that is continuous from the movable portion 34 at a right angle or slightly smaller than the right angle and bends upward at the tip so as to form a lateral L shape when viewed from the front. The length of the movable side holding piece 35 is such that when the movable portion 34 is rotated to be in a hanging posture, the leading end standing piece 35a extends to the other side of the flange portion 61b, that is, the folded plate roof 61 in the flange portion 61b. The length is applied to the side surface on the downstream side in the formation direction (the right side in the drawing), and the tip of the upright piece 35a is used as the pressing surface 35b.

  In addition to the length of the movable portion 34, the length of the other leg portion 22 of the support 12 is such that the lower end is held on the movable side while the tip of the movable side holding piece 35 is in contact with the flange portion 61b. The length is in contact with the base of the piece 35.

  In FIG. 4, 41 is a spring washer and 42 is a washer.

  As shown in FIG. 5, the mounting bracket 11 having such a configuration is used by holding the support body 12 inside the holding body 13 and connecting it with the fastening bottle 14, and fixing the hanging element 71 of a necessary shape. . 5 is fixed in advance to the mounting bracket 11, but in the case of the square rod-shaped hanging lever 71 indicated by a virtual line, the mounting bracket 11 is attached to the folded plate roof. Fix to 61 and attach.

  When fixing the hanger 71, the through-hole 71a of the hanger 71 is inserted into the attachment bolt 36 of the receiving portion 31 and tightened with the nut 36b, but the auxiliary metal fitting 72 may be attached under the nut 36b. As the auxiliary metal fitting 72, there are a plurality of types as shown in FIG.

  One auxiliary metal fitting 72a in the illustrated example has a holding plate portion 73 that overlaps the upper surface of the horizontal surface portion 71b of the hanging element 71, and a standing portion 74 that stands along the vertical surface portion 71c of the hanging element 71 in the holding plate portion 73. It is. In FIG. 5, 75 is a through hole and 76 is a reinforcing rib. In this auxiliary metal fitting 72 a, the pressing plate portion 73 and the standing portion 74 firmly press the hanging element 71.

  The other auxiliary metal fitting 72b extends upward from two sides in a direction perpendicular to the vertical surface portion 71c of the hanging member 71 in the holding plate portion 73, and a holding plate portion 73 that overlaps the upper surface of the horizontal surface portion 71b of the hanging member 71, and on the upper end. It has a receiving piece 77 that spreads outward. The height of the upper surface of the receiving piece 77 is set to the same height as the height of the high top plate portion 31c, which is the highest portion of the receiving portion 31 of the holding body 13 when the hanging element 71 is fixed. In the auxiliary metal fitting 72b, the pressing plate 73 firmly presses the suspension 71 and the receiving piece 77 supports the folded plate 61a.

  In order to fix the mounting bracket 11 to the folded plate roof 61, the mounting bracket 11 is placed so as to be fitted to the flange portion 61b of the folded plate roof 61 as shown in FIG. Subsequently, the fastening bolt 14 is tightened. Then, the movable part 34 of the sandwiching body 13 rotates in a direction approaching the other leg part 22 of the support body 12, and the movable side sandwiching piece 35 advances toward the fixed side sandwiching piece 33 along with this, 7, the pressing portions 35 b and 33 b at the tips of the movable side holding piece 35 and the fixed side holding piece 33 hold the flange portion 61 b of the folded plate roof 61, and the movable side holding piece 35 and the fixed side holding portion. The pieces 33 are in surface contact with the left and right plane portions 61d and 61c of the folded plate roof 61, respectively.

  Thus, in the fixed state in which the fixed side holding piece 33 and the movable side holding piece 35 of the holding body 13 are in contact with the flat surface portions 61 c and 61 d of the folded plate roof 61 and hold the flange portion 61 b, the fastening bolt 14 is connected to the holding body 13. This is maintained by tightening the movable portion 34 in the direction in which the movable portion 34 approaches the other leg portion 22 of the support 12. By tightening the fastening bolt 14, one leg portion 22 of the support body 12 pulls the fixed-side holding piece 33 of the holding body 13 toward the flange portion 61b, and presses the movable-side holding piece 35 against the flange portion 61b. .

  Since the bent portion 21a is formed at the lower end of the one leg portion 21, the strength is high, and the bent portion 21a engages with the standing piece 33c of the fixed-side clamping piece 33, so that it presses against the flange portion 61b. The strength of the portion is further increased, and a strong clamping force can be exhibited.

  The clamping state is maintained by screwing of the fastening bolt 14, but the screw hole 22a into which the fastening bolt 14 is screwed is formed in the other leg portion 22 in which the metal plate is doubled. Compared with the case where a screw is formed, more threads can be obtained, and there is an effect that deformation of a double metal plate is suppressed. For this reason, the clamping pressure by the movable side clamping piece 35 can be ensured, and the clamping condition can be strongly maintained.

  The mounting bracket 11 accommodates the flange portion 61b of the folded plate roof 61, and is fixed to the folded plate roof 61 by the fastening bolts 14 tightened at the lateral position of the flange portion 61b, so that the height when the mounting bracket 11 is fixed is lowered. be able to.

  Further, the clamping to the flange portion 61b is performed by using a part of the clamping body 13 and is not directly pressed by the fastening bolt 14, so that the folded plate 61a is not damaged and can be clamped in a wide range. The clamping strength can be increased. Moreover, since the movable portion 34 of the clamping body 13 is rotationally deformed by tightening with the fastening bolts 14 and is clamped by the movable side clamping pieces 35, the fastening bolts 14 can be made difficult to loosen. Can be maintained.

  When a load from above is applied in the fixed state, the holding body 13 supports the load by the receiving portion 31 and the like, and the support body 12 positioned inside is held by the pair of leg portions 21 and 22 and the connecting portion 23. The load applied to the body 13 is supported. At this time, the lower ends of the pair of legs 21 and 22 of the support 12 are in contact with the sandwiching body 13, and the contact surfaces 24 and 37 of the support 12 and the sandwiching body 13 are also in surface contact with each other. Further, the low top plate portion 23 c in the connecting portion 23 of the support 12 is also in contact with the head portion 36 a of the mounting bolt 36. For this reason, it can receive a load, dispersing well.

  When a load pulled upward is applied, the receiving portion 31 of the holding body 13 is pulled through the suspension 71, and the load is transmitted to the fastening bolt 14, the movable side holding piece 35, and the fixed side holding piece 33. And transmitted to the other leg 22 of the support 12 via the fastening bolt 14. The load is distributed mainly from the other leg portion 22 to the connecting portion 23, the one leg portion 21, and the fixed-side clamping piece 33. In addition, since the one leg portion 21 is engaged with the fixed-side clamping piece 33, the load pulled upward exhibits a tightening force, and a firm fixed state can be maintained.

  Moreover, since the hanging element 71 and the mounting bolt 36 are held by the low top plate part 31b which is the side having the movable side holding piece 35 in the receiving part 31, the load pulled upward is immediately applied to the support body 12. Can communicate. For this reason, load distribution and firm fixation are effectively achieved.

  In this way, the fixing strength can be increased because the load can be dispersed well while downsizing.

  Hereinafter, other examples will be described. In this description, the same parts as those in the configuration of the above-described example are denoted by the same reference numerals, and detailed description thereof is omitted.

  The mounting bracket 11 shown in FIG. 8 is provided with a resin member 81 for heat insulation in the receiving portion 31 of the sandwiching body 13. The configuration of the mounting bracket 11 is not changed except for the dimensions of the receiving portion 31.

  As shown in FIG. 9, the resin member 81 has a shape including a high position surface portion 82 and a low position surface portion 83 that follow the upper surface of the receiving portion 31 of the sandwiching body 13, and a step portion 84 that connects them. Edge portions 85 that cover both front and rear surfaces of the sandwiching body 13 are formed on both sides. An insertion hole 86 through which the attachment bolt 36 is inserted is formed at a position corresponding to the attachment bolt 36 in the low position surface portion 83.

  The insertion hole 86 is usually set to a size that allows a bolt to be inserted slowly, but here, it is set to a size that has little clearance with the mounting bolt 36. That is, the diameter d1 of the mounting bolt 36 and the diameter d2 of the insertion hole 86 are almost the same or the same, or the diameter d1 of the mounting bolt is slightly larger than the diameter d2 of the insertion hole 86. Specifically, a large-diameter hole 86a larger than the diameter of the mounting bolt 36 is formed, and an insertion hole 86 having a size close to the diameter of the mounting bolt 36 is formed in a part of the large-diameter hole 86a in the thickness direction. A restriction piece 86b is provided.

  That is, when the restriction hole 86 of the heat insulating member 81 and the mounting bolt 36 are relatively moved and fitted with each other, the heat insulating member 81 is fitted on the upper surface of the sandwiching body 13, and even if it is shaken even if upside down, the heat insulating member 81 does not move. The fitting state can be maintained without detaching from the sandwiching body 13, and if the heat insulating member 81 is separated from the sandwiching body 13 by applying force, it is in a detached state.

  For this reason, even if it is the structure which has the heat insulation member 81, it can enjoy ease of handling with a simple structure.

  For example, as shown in FIG. 10, the restriction piece 86b may be positioned above the thickness direction of the large-diameter hole 86a (see FIG. 10A) or positioned below the thickness direction of the large-diameter hole 86a. (See FIG. 10B). Further, the restricting piece 86b may be arranged in a circular shape corresponding to the shape of the mounting bolt 36 in plan view to form an insertion hole 86 (see FIG. 10C).

  FIG. 11 shows an example of the mounting bracket 11 provided with a mounting bolt 36 for fixing the suspension 71 on the support body 12 instead of the sandwiching body 13.

  The support 12 of the mounting bracket 11 has the metal plate in the direction in which the metal plate is folded back at the lower end position when forming the other leg portion 22, and to the position where the mounting bolt 36 that fixes the suspension 71 is screwed. It is extended. As a result, a doubled metal plate is formed in the other leg portion 22 and the connecting portion 23, and screw holes 22a and 23d are respectively formed. The screw hole 22 a of the other leg portion 22 is for the fastening bolt 14, and the screw hole 23 d of the receiving portion 23 is for the mounting bolt 36. The hanger 71 is fixed by a mounting bolt 36 that is screwed from above to below.

  Even with the mounting bracket configured as described above, the same effects as described above can be obtained. In addition, since the load by which the mounting bolt 36 to which the hanging element 71 is attached is directly transmitted not only to the sandwiching body 13 but also to the support body 12, the load can be distributed more favorably. Further, since the mounting bolt 36 is screwed into an overlapping portion of the support 12 that is connected to the metal plate constituting the other leg 22, the mounting bolt 36 also functions to maintain the shape of the other leg 22. For this reason, it is possible to further improve the strength of the mounting bracket 11 itself and the mounting bracket 11 fixed to the folded plate roof 61.
