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 left and right members having the clamping pieces are connected by a single bolt extending in the left and right direction, shearing is concentrated on this bolt. A load is applied. Although the metal fitting of patent document 3 has the top plate material which overlaps mutually on the upper end part of a pair of members, since the top plate material of the main body metal fitting which has a mounting bolt is located above, the part which supports a load is other than a bolt Is only a slide structure between the top plates, and since the slide structure has a clearance, the load applied to the bolt is not effectively dispersed.

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 protruding portion on the upper surface, and the protruding portion is sandwiched between a pair of left and right sandwiching portions on the roof. Mounted and supports the mounting on top. The mounting bracket is used to fix a roof plate as an attachment for the purpose of renovation, or to fix an installation such as a solar cell panel or a snow stopper as an attachment for the purpose of imparting a function. In this description, an example of a roof structure using a mounting bracket used for the purpose of repairing the former will be described.

  In FIG. 1, sectional drawing of the principal part of the use condition of the attachment metal fitting 11 is shown. As shown in FIG. 2, the mounting bracket 11 is mounted on the lower roof 51 and fixes the upper roof 52. The lower roof 51 and the upper roof 52 are folded plate roofs 61, and are formed by joining a plurality of folded plates 62 at the flanges 63. In the drawing, the round roof type folded plate roof 61 is drawn, but other types of folded plate roofs such as a square wall type may be used.

  In addition to the roof, the folded plate roof 61, which is an example, has a waveform that repeats a peak and a valley, and on the top surface of the peak, the left and right flat portions 64 and 65, and the ridges sandwiched between them. It has the collar part 63 of. The plane portions 64 and 65 are drawn with a slight inclination in the illustrated example, but there are also horizontal portions. The roof may be a saddle type folded plate roof, a mated 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 and a tightening body 13. The support 12 is shaped so as to straddle the collar part 63 from one planar part 64 to the other planar part 65 of the planar parts 64, 65 of the folded plate roof 61, and the flat part is applied to one end of the collar part 63. One clamping part 21 mounted on 64 is provided at the lower end. The fastening body 13 is attached to the other side of the support body 12, and has the other clamping part 31 on the other side of the collar part 63 and the other clamping part 31 that rests on the flat part 65 at the lower end. The support 12 and the sandwiching body 13 are formed by pressing a metal plate. Although the support body 12 and the sandwiching body 13 are each shown as an example manufactured from one metal plate, a plurality of members may be combined.

  FIG. 3 is a perspective view of a state in which the support 13 and the fastening body 13 are combined, and FIG. 4 is a perspective view of the exploded state.

  As shown in these drawings, the support 12 is formed by bending a metal plate having a predetermined width, and the schematic shape in a front view is an inverted concave shape. The support 12 has a vertical piece 22 on one side in the left-right direction (left side in the drawing, the same applies hereinafter), and inward, that is, on the other side (right side in the drawing, the same applies hereinafter) at the lower end of the vertical piece 22. It has the one clamping part 21 mentioned above. A bent edge 21 a that bends upward is formed at the tip edge of the sandwiching portion 21. At the upper end of the vertical piece 22, there is an upper surface portion 23 positioned above the collar portion 63, and a hanging piece 24 is formed at the other end of the upper surface portion 23.

  The upper surface part 23 has a step part 23a that makes the other side lower than the one side at the middle part in the left-right direction, a lower surface 23b that has a lower height at the step part 23a, and a height that is higher than the lower surface 23b. An upper surface 23c is provided. The height of the lower surface 23b is set as low as possible among the heights that can accommodate the flange portion 63 of the lower roof 51 to be attached, and the height of the upper surface 23c is set as low as possible. The step portion 23a is set to be higher than at least the thickness of the plate material constituting the tightening body 13. In the illustrated example, the step portion 23a is formed vertically, but may be formed obliquely.

  The lower surface 23b is a portion for fixing the suspension 14 (see FIGS. 1 and 2) for fixing the upper roof 52, and a fixing bolt 25 with its tip facing upward is fixed at the center. The fixing bolt 25 has a head portion 25a, is inserted from below the lower surface 23b, and is fixed by caulking the root portion on the head portion 25a side. The height of the tip of the fixing bolt 25 is set to be equal to or lower than the height of the upper surface 23c.

  At both ends of the stepped portion 23a in the width direction, insertion portions 26 penetrating in the left-right direction are formed. The insertion portion 26 is formed by cutting from the end in the width direction at the lower end portion of the step portion 23 a, and the height of the insertion portion 26 is a height corresponding to the thickness of the plate material constituting the tightening body 13. That is, the lower end position of the insertion portion 26 is the same height as the upper surface height of the lower surface 23a, and a part of the tightening body 13 overlapping the lower surface 23b is pierced straight into the insertion portion 26. The width of the insertion part 26 is appropriately set.

  From the stepped portion 23a to the upper surface 23c, the vertical piece 22, and one clamping portion 21, a reinforcing rib 27 is formed inwardly at the center in the width direction. Reinforcing ribs 28 are formed on the hanging piece 24 from the lower surface 23b so as to protrude inward at both sides in the width direction avoiding the fixing bolt 25.

  A fastening bolt 29 is fixed to the central portion of the hanging piece 24 so that the tip is directed outward in the left-right direction, that is, toward the other side. The fastening bolt 29 is positioned in the same straight line as the fixing bolt 25 in plan view. The fastening bolt 29 is also passed from the inside of the hanging piece 24 and is fixed by caulking the base portion on the head 29a side. The length of the fastening bolt 29 is long as long as the upper roof 52 can be fixed, and when the tip of the clamping part 31 of the fastening body 13 is brought close to the inside of the hanging piece 24 of the support body 12, The length of the fastening bolt 29 is set so as not to contact the fastening body 13.

  The fastening body 13 is formed by bending a metal plate having the same width as that of the support body 12 and has a substantially U shape in front view. The fastening body 13 includes a superposed piece 32 that overlaps the lower surface 23 b of the upper surface portion 23 of the support 12, a pressure receiving piece 33 that descends from the other end of the superposed piece 32, and an inner side from the lower end of the pressure receiving piece 33. That is, it has the other clamping part 31 extended toward one side. A bent edge 31 a that bends upward is formed at the tip edge of the sandwiching portion 31.

  The main body portion of the superposed piece 32 is formed in a size substantially corresponding to the lower surface 32 b, and the pressure receiving piece 33 is the hanging piece 24 of the support body 12 when the end on one side is brought close to the stepped portion 23 a of the support body 12. Is in contact with or close to the size. A cutout 34 having a width wider than the diameter of the fixing bolt 25 is formed in the overlapping piece 32 by cutting from one end. That is, the notch 34 has a long hole shape with one end opened. The width of the notch 34 is set to a width corresponding to the diameter of the fixing bolt 25, in other words, slightly wider than the diameter. For this reason, as shown in FIG. 5, when the nut 15 is screwed onto the fixing bolt 25 and tightened, the nut 15, more specifically, a washer integrally provided under the nut 15 as shown in the drawing, A to-be-tightened portion 35 that is fastened by a washer provided in a separate body is formed around the notch 34.

  In addition, a pair of insertion portions 36 to be inserted into the insertion portion of the support 12 are formed at one end on both sides in the width direction across the notch 34 in the polymer piece 32. The upper surface height of the insertion portion 36 and the overlapped piece 32 is the same, that is, is flush. The insertion portion 36 has a plate shape with a width corresponding to the width of the insertion portion 26 and is set to a narrow width having appropriate rigidity.

  As shown in FIGS. 6 and 7, the length of the insertion part 36 is such that when the tip of the clamping part 31 of the tightening body 13 is brought close to the inside of the hanging piece 24 of the support body 12, the tip is inserted into the insertion part 26. It is the length to be close to. Specifically, when the bent edge 31 a at the tip of the sandwiching portion 31 is hooked inside the lower end of the hanging piece 24, the tip is positioned at the front side of the entrance of the insertion portion 26.

  A through hole 37 through which the tightening bolt 29 is inserted is formed at a position corresponding to the tightening bolt 29 when the superposed piece 32 is overlapped with the lower surface 32b of the support body 12 in the central portion of the pressure receiving piece 33. . The through hole 37 has a size corresponding to the diameter of the fastening bolt 29.

  The fastening bolt 29 is provided with a nut 16. As shown in FIG. 3, the nut 16 is screwed to a tightening bolt 29 in a state where the tightening body 13 is combined, and the periphery of the through hole 37 of the pressure receiving piece 33 is brought to the drooping piece 24 side of the support body 12 by screwing. The clamping body 13 is moved by pressing.

  The mounting bracket 11 composed of each member as described above is used by assembling the fastening body 13 to the support body 12.

  The assembling is simple when the bent edge 31a of the clamping part 31 of the tightening body 13 is hooked and rotated inside the lower end of the hanging piece 24 of the support 12 and the overlapping piece 32 is stacked on the lower surface 23b. This is because the length of the insertion portion 36 is set such that the tip is brought close to the insertion portion 26 when the tip of the clamping portion 31 of the fastening body 13 is brought close to the inside of the hanging piece 24 of the support body 12. Is formed so that the tip does not come into contact with the tightening body 13 when the tip of the clamping part 31 of the tightening body 13 is brought close to the inside of the hanging piece 24 of the support body 12. Because.

  The lower surface 23b and the overlapping piece 32 superimposed on the lower surface 23b regulate the positional relationship between them. For this reason, it fulfills the function of guidance when moving the fastening body 13 toward the support body 12 side. When the support body 12 and the tightening body 13 are relatively moved in the proximity direction, the insertion portion 36 enters the insertion portion 26 of the stepped portion 23 a, the fixing bolt 25 enters the notch 34, and the tightening bolt 29 becomes the pressure receiving piece 33. Enter the through hole 37. These also serve as guidance. Accordingly, the relative movement for bringing them closer together can be performed smoothly and straight, and desired assembly can be easily performed.

  In particular, since the insertion portion 36 is provided and the length of the insertion portion 36 is set to the maximum as described above, the length in which guidance is performed is increased as compared with the case where the insertion portion 36 is not provided. The operability is good. In addition, since a pair of insertion portions 36 are formed on both sides in the width direction of the polymer piece, the stability is good, and it is possible to avoid inadvertent tilting. For this reason, the insertion of the tightening bolt 29 into the through hole 37 can be naturally performed without being particularly conscious.

  After the above-described parts are guided and the desired assembly is performed, the assembled state is maintained when the nut 16 is screwed onto the fastening bolt 29.

  The mounting bracket 11 assembled in this way is used in the field as follows.

  As shown in FIG. 8, in order to attach to the lower roof 51, the fastening body 13 is moved in a direction away from the support body 12, and an interval between the pair of sandwiching portions 21 and 31 is opened. At this time, the nut 16 may be removed from the fastening bolt 29 if necessary.

  Next, the mounting bracket 11 having the space between the sandwiching portions 21 and 31 is covered from above with the flange portion 63 of the lower roof 51, and the pair of sandwiching portions 21 and 31 are placed on the horizontal portions 64 and 65, respectively. 12 and the fastening body 13 are moved relative to each other. This relative movement is straight in the left-right direction because the insertion portion 36 and insertion portion 26, the fixing bolt 25 and the notch 34, the fastening bolt 29 and the through hole 37, and the lower surface 23a and the overlapping piece 32 serve as a guide, It can be done smoothly.

  The gap between the pair of sandwiching portions 21 and 31 is narrowed so that the lower portion of the flange portion 63 is sandwiched, and then the tightening bolt 29 positioned beside the flange portion 63 is tightened with the nut 16. The relative movement described above may be performed by screwing the nut 16. As described above, since the plurality of parts serve as a guide, the nut 16 can be smoothly rotated and relatively moved.

  When the nut 16 is tightened, the mounting bracket 11 is fixed to the flange 63 of the lower roof 51. At this time, the hanging piece 24 of the support body 12 and the pressure receiving piece 33 of the tightening body 13 come close to each other or come into surface contact with each other and are joined and integrated by the tightening bolt 29.

  Thereafter, the suspension 14 is fixed on the mounting bracket 11. That is, as shown in FIG. 1, the through hole 14a of the suspension 14 is inserted into the fixing bolt 25 extending upward from the lower surface 23b of the support 12 through the cutout 34 of the overlapping piece 32 of the fastening body 13. Then, the periphery of the through hole 14a of the suspension 14 is tightened with the nut 15 screwed into the fixing bolt 25. By this tightening, the lower surface of the hanging element 14 presses the tightened portion 35 of the superposed piece 32 of the tightening body 13 against the lower surface 23b of the support body 12, and the joining and integration are performed in a state where the superposed piece 32 is sandwiched. The

  As a result, the support 12 and the tightening body 13 come into close contact with each other at the portion having the fixing bolt 25, and the contact area increases to obtain high unity. Therefore, the load is distributed to other parts, and only the tightening bolt 29 portion is obtained. To prevent a high load from being applied.

  That is, when a load is applied from above, the load applied to the fixing bolt 15, the overlapping piece 32, the lower surface 23 b and the load applied to the upper surface 23 c are immediately transmitted to other parts, and mainly the vertical piece 22 The hanging piece 24 and the pressure receiving piece 33 support it. When a load pulled upward is applied, the load applied to the lower surface 23 b and the overlapping piece 32 from the fixing bolt 15 is immediately transmitted to the vertical piece 22, the hanging piece 24, and the pressure receiving piece 33. In either case, the pair of sandwiching portions 21 and 31 maintains firm fixation by the integrity of the fixing bolt 15 portion and the fastening bolt 29 portion having different directions. That is, load distribution and firm fixation are effectively achieved.

  As described above, in the roof structure using the mounting bracket 11, the tightening bolt 29 is positioned beside the flange portion 63, and thereby the mounting to the lower roof 51 is performed. The height can be lowered.

  In addition, the support 12 and the fastening body 31 which are separate members are joined and integrated at two places where the directions of the shafts (fixing bolts 25 and fastening bolts 29) for joining are different at the time of use. Since the contact area can be increased at the bolt 25 portion, it is possible to effectively disperse the load and increase the strength against both positive pressure and negative pressure. In the joint integration of the fixing bolt 25 portion, since the tightened portion 35 is provided around the notch 34 of the superposed piece 32, positive clamping is performed, and also in this respect, firm fixation can be performed.

  Further, since the fastening bolt 29 is fixed to the support 12 and screwing is performed by the nut 16, the number of screw threads to be applied is larger than that of screwing with a metal plate formed by burring to form a female screw. Since it can do, intensity | strength can also be raised also at the point which can perform stronger fastening.

  Other examples will be described below. In this description, the same parts as those described above are denoted by the same reference numerals, and detailed description thereof is omitted.

  FIG. 9 is a perspective view of the mounting bracket 11 in an assembled state according to another example. As shown in this figure, ribs 38 may be formed on both outer sides of the overlapping piece 32 and the insertion portion 36 of the fastening body 13. The rib 38 is formed by bending the edge downward. The rib 38 improves the strength and has a guiding function. The rib 38 can also be formed continuously on the pressure receiving piece 33 as shown in FIG.

  The ribs 38 may be formed by being bent at the edges, or may be bulged by punching as shown in FIG. In this case, the rib 38 may be formed in a linear shape extending in the vertical direction on both sides in the width direction of the pressure receiving piece 33.

  FIG. 12 is a perspective view of the mounting bracket 11 in an assembled state according to another example, and the insertion portion 36 (see FIG. 3) of the tightening body 13 may be omitted as shown in FIG. In connection with this, the insertion part 26 (refer FIG. 3) of the level | step-difference part 23a of the support body 12 is also abbreviate | omitted.

  FIG. 13 is a plan view of the mounting bracket 11 in an assembled state according to another example, and the cutout 34 of the overlap piece 32 may be formed larger than the diameter of the fixing bolt 25 as shown in this figure. . The size of the notch 34 is formed so as not to have a tightened portion 35 (see FIG. 5) that is fastened by the nut 15 screwed into the fixing bolt 25, that is, wider than the crimping surface of the nut 15. Even if it comprises in this way, since the lower surface of the hanging element 14 pinches | interposes the superposition | polymerization piece 32, firm coupling | bonding integration is made | formed.

  The present invention is not limited to the above-described configuration, and other configurations can be employed.

  For example, the fixing bolt 25 for fixing the attachment may be another bolt such as a sword tip bolt, and is appropriately set according to an object (attachment) to be fixed by the roof mounting bracket 11.

  The insertion portion 36 is not flush with the overlapping piece 32 but is formed higher than that through a step, and accordingly, the height of the insertion portion 26 is set to an intermediate portion of the height of the step portion 23a or the like. You can also.
