Japanese Patent No. 30624458

  For example, in the case where the roof fixing bracket having the fixing portion for the vertical roof is provided with a snow slat blade portion or a snow fixing bracket can be attached, the fixing portion is fixed (the roof fixing bracket is attached). When a large load of snow is applied to the slats and snow guards after installation and fixing on the vertical roof, the slats are lifted upwards, causing the slats to fall to the eave side of the roof. A strong force to act will act.

  Also, in the case of a metal fitting to which a solar panel can be attached, when the solar panel is blown up in a strong wind, a strong force is also applied to lift the fixing portion upward.

  In either case, depending on the magnitude of the acting force, there is a concern that the fixing portion may be lifted and come off upward.

  The present invention intends to eliminate such a concern, and provides an innovative roof fixing metal fitting that can be extremely firmly fixed to a vertical roof.

  The gist of the present invention will be described with reference to the accompanying drawings.

Snowflake blades or snowfitting metal fittings, solar panels 1A, snow melting devices, attachment parts 2 on which roof installations 1 such as their fixtures 1B can be attached, and superposed projections on which vertical roofs R are erected In the roof fixing bracket comprising a fixing portion 6 that can be clamped and fixed to the strip portion 3, the fixing portion 6 has a fastening bolt 9 installed between a pair of left and right clamping bodies 7 that can clamp the superposed convex strip portion 3. And the protrusion 11 for clamping which contact | abuts the base part 5 of the superposition convex part 3 of the said vertical roof R is opposed to each clamping body 7 in the several lower part of the opposing surface 8 of this pair of right and left clamping bodies 7. By projecting in a bulging state from the facing surface 8 toward the inside of the surface 8, the tightening bolt 9 is tightened and turned or the nut 10 screwed to the tightening bolt 9 is tightened and turned. The gap between the pair of sandwiching bodies 7 is narrowed so that the facing distance between the left and right sandwiching projections 11 is narrowed. Thus, the base portion 5 of the overlapping ridge portion 3 is clamped and clamped, and the fixing portion 6 clamped by the left and right clamping projections 11 moves upward relative to the overlapping ridge portion 3. In this case, the engaging portion 12 that is engaged with the wide connecting portion 4 such as the seam fastening portion 4A and the fitting portion existing above the root portion 5 of the overlapping protruding portion 3 is provided on the upper portion of the sandwiching protrusion 11. The sandwiching projection 11 moves to the lower side of the roof slope of the vertical roof R, on the side of the sandwiching projection 11 that is arranged on the lower side of the roof slope with respect to the vertical roof R. In this case, a corner bracket 25 that bites into the root portion 5 is provided .

  The plurality of clamping projections 11 of the right clamping body 7 and the plurality of clamping projections 11 of the left clamping body 7 are provided at left and right opposing positions. This relates to the described roof fixing bracket.

  Further, the upper part of the sandwiching protrusion 11 is formed in a horizontal surface or an inclined surface that can be brought into contact with and locked to the lower part of the wide connecting portion 4 of the overlapping projection 3, and the horizontal surface or the inclined surface is It is set as the latching | locking part 12, It concerns on the fixed metal fitting for roofs of any one of Claim 1,2.

  Further, by pressing the lower part of the opposing outer surface of the sandwiching body 7 from the outside, the lower part of the opposing surface 8 of the sandwiching body 7 is deformed so as to bulge out from the opposing surface 8, 4. The roof fixing bracket according to claim 1, wherein the bulging deformed portion is the holding protrusion 11.

  Further, the pair of left and right sandwiching bodies 7 are configured by adopting two plate members 7, and the fastening bolts 9 are disposed between the two plate members 7 with the plate surfaces of the two plate members 7 facing left and right. The fixing for roof according to any one of claims 1 to 4, characterized in that the sandwiching protrusion 11 protrudes below the opposing plate surface 8 of each of the two plates. It relates to metal fittings.

Since the present invention is configured as described above, a large load of snow is applied to the snow stop fittings attached to the slats or the attachment part, or a large blowing force due to strong wind acts on the solar panel attached to the attachment part. However, the fixed part exerts a high fixing strength, and it is firmly prevented that the fixed part protrudes upward from the vertical protruding part of the vertical roof , and the downward movement of the vertical slope of the vertical roof is attempted. In this case, the roof fixing bracket is extremely practical and reliable, and exhibits a strong resistance (positioning effect) .

  Further, in the invention according to claim 2, since the sandwiching protrusions clamp and sandwich the left and right positions of the base portion of the overlapping projections, for example, the plurality of sandwiching protrusions are staggered from the left and right at the root portion. Compared to the configuration in which the clamping part is abutted against and clamped, the root part is less likely to be deformed. Therefore, the clamping protrusion is kept firmly in contact with the root part and the clamping part is fixed (fixed part is fixed). It becomes a roof fixture with excellent practicality, which is even more solid.

  Moreover, in invention of Claim 3, even if a fixing | fixed part moves up with respect to the superposition convex part of a vertical roof, the horizontal surface or inclined surface as a latching | locking part is a wide connection part of a superposition convex part. A roof fixing bracket having a more practical structure that can be surely brought into contact with and locked to the lower portion and can effectively prevent the fixing portion from coming off is obtained.

  Further, in the invention described in claim 4, it is a roof fixing bracket having a more practical configuration that makes it possible to easily design and realize a sandwiching body having a sandwiching protrusion having a high deformation resistance strength on the opposing surface. .

  Further, in the invention described in claim 5, since the pair of left and right holding bodies can be designed and realized with two plate members, and a short tightening bolt can be adopted, an inexpensive product can be provided.

FIG. 3 is a sectional view taken along line B-B in FIG. 2. It is a partial expanded explanatory view which shows the protrusion for clamping of a present Example.

  An embodiment of the present invention which is considered to be suitable will be briefly described with reference to the drawings showing the operation of the present invention.

  The fixing portion 6 is arranged on the vertical roof R so as to sandwich the overlapping projection 3 that is erected by the pair of left and right sandwiching bodies 7, and the tightening bolt 9 installed between the pair of left and right sandwiching bodies 7 is tightened and rotated. Alternatively, when the nut 10 screwed on the tightening bolt 9 is tightened and rotated, the space between the pair of left and right sandwiching bodies 7 is narrowed so as to protrude from a plurality of locations below the opposing surface 8 of the sandwiching body 7. The opposing spacing of the sandwiching projections 11 is narrowed, and the plurality of sandwiching projections 11 abut against the root portion 5 of the superposed projection 3 from the left and right, and are clamped and clamped to fix the fixing portion 6 (for the roof of the present invention). The fixing bracket) is fixed on the vertical roof R.

  For example, in the case of a main bracket provided with a blade plate portion or having a snow stopper bracket attached to the attachment portion 2, the snow stopper function is exhibited on the vertical roof R, but the snow plate bracket or the snow stopper bracket has a snow cover. When a large load is applied, a force acts to lift up the fixing portion 6 existing on the ridge side so that the slats or the snow stoppers are inclined to the eave side of the vertical roof R.

  And if this force is very strong, the fixing part 6 (the pair of left and right sandwiching bodies 7) may move up with respect to the superposed convex ridge part 3, but in the present invention, the fixing part 6 is the upper part. When it moves, the locking part 12 provided on the upper part of the sandwiching protrusion 11 is locked to the wide connecting part 4 such as the seam fastening part 4A or the fitting part on the upper part of the overlapping convex part 3, and this locking part. From the position where 12 is locked to the wide connecting portion 4, it cannot move up.

  Therefore, the fixing portion 6 does not come off upward with respect to the superposed protrusion 3.

  Further, for example, in the case of a metal fitting in which the installation object 1 on the roof such as the solar panel 1A, the snow melting device or the attachment 1B is attached to the attachment part 2, the installation object 1 on the roof is blown upward by a strong wind. In this situation, the fixing portion 6 does not slip out upward with respect to the superposed projections 3 in the same manner as described above. .

Further, when the sandwiching projection 11 is about to move to the lower side of the roof slope of the vertical roof R, the sandwiching projection 11 is arranged on the lower side of the roof slope with respect to the vertical roof R. The corner portion 25 provided on the side portion that bites into the base portion 5 exhibits a strong resistance (positioning effect) to the downward movement of the roof slope of the sandwiching projection 11.

  Further, for example, if the plurality of clamping protrusions 11 of the right sandwiching body 7 and the plurality of sandwiching protrusions 11 of the left sandwiching body 7 are provided at the left and right facing positions, the overlapping ridges Thus, the clamping protrusions 11 come into contact with the left and right opposing positions of the three root parts 5 from the left and right, and the clamping protrusions 11 are clamped and clamped at the left and right opposing positions. Therefore, for example, the root portion 5 is less likely to be deformed compared to a configuration in which the plurality of sandwiching protrusions 11 are in a zigzag manner on the left and right sides of the root portion 5 of the superposed projection 3 and tightened and pinched (root). (There is no loss of tightening strength due to deformation of the portion 5), so that the contact state of the pinching projection 11 with the root portion 5 is firmly maintained, and the tightening and pinching state becomes strong.

  Further, for example, the upper part of the sandwiching protrusion 11 is formed on a horizontal surface or an inclined surface that can be brought into contact with and locked to the lower part of the wide connection portion 4 of the overlapping projection 3, and the horizontal surface or the inclined surface. If the fixing part 6 is moved upward with respect to the overlapping ridge part 3 of the vertical roof R, the engaging part 12 which is a horizontal surface or an inclined surface becomes the overlapping ridge part 3. By securely engaging with the lower portion of the wide connecting portion 4, the upward retaining action is exhibited very well.

  Further, for example, by pressing the lower part of the opposing outer surface of the sandwiching body 7 from the outside, the lower part of the opposing surface 8 of the sandwiching body 7 is deformed so as to bulge from the opposing surface 8, and this opposing surface If the bulging deformed portion 8 is the clamping projection 11, the clamping body 7 can be constructed, for example, by integrally forming the clamping projection 11 on the opposing surface 8 by press molding or the like. Since the protrusion 11 is formed integrally with the constituent material of the holding body 7, the holding protrusion 11 has high deformation resistance.

  In addition, for example, the pair of left and right sandwiching bodies 7 are configured by adopting two plate members 7, and the tightening between the two plate members 7 with the plate surfaces of the two plate members 7 facing left and right. If the bolts 9 are installed and the holding projections 11 are provided below the opposing plate surfaces 8 of the two plates, the pair of left and right holding members 7 can be easily designed with the two plates 7. In addition, the material cost can be reduced and the width of the left and right can be reduced as compared to the case where a single plate material as in Patent Document 1 is bent into a U-shape to form a clamping and clamping portion. Since the small fixing part 6 can be configured, the fastening bolt 9 can be short and inexpensive.

  Specific embodiments of the present invention will be described with reference to the drawings.

  In the present embodiment, a mounting portion 2 to which an installation object 1 on the roof such as a snow stop fitting, a solar panel 1A, a snow melting device, or a fixture 1B thereof can be mounted, and a superposed ridge portion 3 on which a vertical roof R is erected. This relates to a roof fixture comprising a fixing portion 6 that can be clamped and fixed to the roof.

  Specifically, the mounting portion 2 of the present embodiment includes a mounting bolt 13 and two installation object mounting nuts 14 that are screwed to the mounting bolt 13, and are screwed to the mounting bolt 13. The installation object 1 on the roof can be clamped and clamped between the two installation object mounting nuts 14. 3 to 5 show a case where the fixture 1B (loading platform) is mounted and fixed to the mounting bolt 13 by using the installation nut 14 and the solar panel 15 is fixed to the fixture 1B. However, it is also possible to attach another installation object 1 on the roof.

  In the fixing portion 6 of this embodiment, a sandwiching body 7 is arranged in a left-right facing state, and a plurality of (two in the drawing) fastening bolts 9 are installed between the left and right plate members 7. By screwing the nut 10 to the left and right, the left and right clamping bodies 7 can be prevented from coming off with respect to the clamping bolt 9, and the nut 10 can be tightened and rotated so that the facing distance between the left and right clamping bodies 7 can be reduced. It is configured.

  The sandwiching body 7 is composed of two horizontal rectangular metal plates 7, and the plate surfaces of the plates 7 are opposed to each other. Therefore, since the sandwiching body 7 is composed of two metal plate materials 7, it can be designed at a low component cost, and the fixed plate 6 is configured with the plate surfaces of the two plate materials 7 facing left and right. Therefore, the fixing portion 6 has a very small left and right width of about two plate thicknesses of the plate material 7, and the fastening bolt 9 can be fixed at a low cost because an inexpensive short bolt is sufficient. The part 6 can be configured.

  In addition, a sandwiching protrusion 11 is provided on the opposing plate surface 8 at the lower end of each of the pair of left and right sandwiching bodies 7 so as to abut on the root portion 5 of the overlapping projection 3 of the vertical roof R. That is, the fixing portion 6 of the present embodiment tightens and rotates the nut 10 to narrow the spacing between the holding members 7 of the pair of left and right holding members 7, thereby holding the lower protrusions of the left and right holding members 7. The portion 11 is configured to be clamped and fixed by being brought into pressure contact with both the left and right side surfaces of the thin (thin width) base portion 5 of the superposed protrusion 3.

  In addition, the sandwiching projections 11 are provided with sandwiching projections 11 at several locations (three locations in the drawing) spaced apart in the length direction of the sandwiching body 7, and a plurality of the sandwiching projections 11 of the right sandwiching body 7. The projecting projection 11 and the plurality of clamping projections 11 of the left sandwiching body 7 are provided at the left and right facing positions (laterally symmetrical positions). Accordingly, a plurality of sandwiching protrusions 11 provided on each side are in contact with each other so as to abut on both side surfaces of the left and right opposing positions of the root portion 5 of the superposed projection 3 to firmly secure the plurality of left and right opposing positions. It is set as the structure clamped to.

  The clamping protrusion 11 will be described in more detail with reference to FIG. 7A is a partially enlarged perspective view of the sandwiching projection 11, FIG. 7B is a partially enlarged front sectional view of the sandwiching projection 11, and FIG. 7C is a portion of the sandwiching projection 11. It is an enlarged plan view.

  Each of the sandwiching protrusions 11 has a shape that swells in a substantially square shape.

  Each of the sandwiching protrusions 11 has a bulging tip portion formed in a flat surface shape having a surface direction in a vertical direction (a direction parallel to the surface direction of the facing surface 8). However, it is set as the structure contact-contacted with respect to the left and right both sides | surfaces of the root part 5 of the superposition convex part 3 of the vertical roof R.

In addition, each clamping protrusion 11 is formed in a flat surface shape having a surface direction in a direction orthogonal to the surface direction of the bulging tip surface 23 at the upper side and the eaves side, so that the flat upper surface is formed. The connecting portion between the side surface 12 and the bulging tip surface 23 and the connecting portion between the eaves side surface 24 and the bulging tip surface 23 are configured to form a substantially right corner 25 (corner edge 25 ). Yes. That is, the sandwiching protrusion 11 has a corner edge 25 on the upper side and the eave side.

  Therefore, with the fixing portion 6 being clamped and fixed to the superposed projection 3, the clamping projection 11 tries to move to the eave side (downward side of the roof slope) of the vertical roof R or to move upward. In this case, the corner edge portion 25 can easily bite into the left and right side portions of the base portion 5, which acts as a wedge and exerts a strong resistance to movement toward the eaves side and upward movement. It has a configuration (demonstrating a strong positioning effect).

  Further, each of the sandwiching protrusions 11 is formed by, for example, press-pressing so that the outer plate surface of the lower end of each of the left and right sandwiching bodies 7 is recessed inward, so that the opposing surfaces 8 of the respective lower ends are formed. It is comprised with the protrusion deform | transformed so that it may bulge to the opposing inner side. In other words, the sandwiching protrusion 11 is integrally formed on the plate surface at the lower end of the left and right sandwiching bodies 7 (see FIG. 7B). Reference numeral 27 in the figure denotes a pressing mark (recess).

  Further, in this embodiment, when the pair of left and right sandwiching bodies 7 move upward with respect to the superposed convex ridges 3 at the upper part of the respective projecting projections 11, the gouge fastening part 4 </ b> A above the superposed convex ridges 3. A locking portion 12 that locks to the wide connecting portion 4 such as a fitting portion is provided.

  Specifically, each clamping protrusion 11 has a shape having the upper side surface 12 that is substantially horizontal in the upper portion as described above, and the upper side surface 12 serves as the locking portion 12.

  Therefore, in a state where the fixing portion 6 is fixed on the vertical roof R, when a large blowing force due to strong wind acts on the solar panel 1A, a force for lifting the fixing portion 6 upwards acts. When the pinching protrusion 11 that is in contact with the base portion 5 of the superposed convex portion 3 moves upward, the gouge fastening of the superposed convex portion 3 having a thickness (width) is larger than the base portion 5 existing above the base portion 5. The locking portion 12 at the upper portion of the holding projection 11 is locked to the lower portion of the portion 4A (the wide connecting portion 4) and cannot be moved any further. It is set as the structure which cannot be pulled out upward and the fixed state to the superposition convex part 3 (vertical roof R) is hold | maintained firmly (refer FIG. 5). The locking portion 12 may be formed on an inclined surface that is slightly inclined with respect to the horizontal.

  In this embodiment, the mounting portion 2 and the fixing portion 6 are mounted using a mounting substrate 15.

  Specifically, the mounting substrate 15 is formed in a shape in which a metal strip is bent in an L shape and a front plate portion 16 and a bolt mounting plate portion 17 that are arranged on the eave side are connected substantially at right angles. doing. Further, a clearance recess 26 for escaping the superposed protrusion 3 is formed in the lower portion of the front plate portion 16, and the mounting portion 2 is provided at a substantially central portion of the bolt mounting plate portion 17 of the mounting substrate 15. The mounting bolt 13 to be configured is fixed in an upright state facing upward.

  Further, front end portions arranged on the eaves side of the respective sandwiching bodies 7 constituting the fixing portion 6 are bent at substantially right angles to the opposite outer sides, and this bent plate portion is connected to the front plate portion 16 of the mounting substrate 15. The mounting plate portion 18 is superposed on the back surface portion of the base plate, and each mounting plate portion 18 and the superposed front plate portion 16 are attached with rivets 19 and screws 20 (and nuts 21). The attachment portion 2 and the fixed portion 6 are attached to each other.

  Further, one mounting plate 18 is provided with a long hole-shaped screw through hole 23, and by loosening the screw 20, the facing distance between the pair of left and right sandwiching bodies 7 can be adjusted to be wide or narrow.

  Note that the present invention is not limited to this embodiment, and the specific configuration of each component can be designed as appropriate.

  For example, in this embodiment, a case is shown in which the present invention is applied to a roof mounting bracket having a mounting portion 2 to which a roof installation object 1 such as a snow stop bracket, a solar panel 1A, a snow melting device, or a mounting tool 1B thereof can be mounted.
