Japanese Patent Application No. 2009-194302

  There are flat roofs and stepped roofs in the side roof, and the stepped roof has a stepped shape in which the overlapped plate portion for joining the roof plate materials is higher than that of the flat roof.

  When the above-mentioned Patent Document 1 is used for such a stepped roof, the overlapping plate portion for joining the roof plate material is easily deformed by the height, so that if the clamping portion is too tight, the upper clamping plate There is a concern that the downward locking edge portion of the portion may deeply bite into the upper surface of the joining overlapping plate portion of the roof plate material, causing the upper surface to warp, resulting in a decrease in fixing strength.

  In addition, since the engaging edge portion bites deeply into the upper surface of the joining overlapping plate portion of the roof plate material, the coating of the roof plate material is easily peeled off, and there is a concern about the occurrence of rust from the place where the coating is peeled off.

  The present invention was developed in order to eliminate the concern that arises in the use of such a stepped roof, and when it is sandwiched and fixed to the overlapping plate part for joining the roof plate material of the stepped roof by the sandwiching part, It is intended to provide an installation fixture for a roof that is unlikely to cause deformation on the upper surface of the superposed plate portion and to prevent paint peeling.

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

  On the upper part of the metal fitting body A provided with a clamping portion 3 that is clamped and fixed from above and below to the superposed bonding plate portion 2 of the roof plate material 1 for the horizontal roof R, a snow stop fitting, a solar panel 4A, In a roof installation fixture having a mounting portion 5 to which a roof installation article 4 such as a snow melting device or a fixture 4B thereof can be attached, a single metal plate 6 is bent into a substantially U shape. The upper body clamping plate A of the bracket body A is configured such that upper and lower clamping plates 8 and 9 are connected to the upper and lower ends of the back plate 7 in a vertically opposed state. 8 and the lower clamping plate portion 9 are installed with a tightening bolt 10, and the tightening bolt 10 is tightened and rotated or the nut 11 screwed to the tightening bolt 10 is tightened and rotated. By narrowing the facing distance between the upper sandwiching plate portion 8 and the lower sandwiching plate portion 9, the overlapping overlapping laminate plate portion 2 of the roof plate member 1 is The clamping plate portion 8 and the lower clamping plate portion 9 constitute the clamping portion 3 that is clamped and fixed from above and below, and the front end portion of the upper clamping plate portion 8 of the clamping portion 3 is substantially L-shaped downward. By bending, the lower surface of the bent front plate portion 12 and the lower end plate portion of the lower holding plate portion 9 are provided in an opposing state, and the lower surface of the bent front plate portion 12 is joined to the roof plate 1. A surface contact portion 13 that makes a surface contact with the upper surface of the superposition plate portion 2 is formed, and the surface contact portion 13 is formed in a shape having a length along the lateral direction of the superposition plate portion 2 for bonding. A roof installation fixture having a plurality of engaging projections 14 projectingly engaged with the upper surface of the joining overlapped plate portion 2 at intervals in the length direction of the surface contacting portion 13 It is concerned.

  Further, by pressing a plurality of locations on the upper surface of the bent front end plate portion 12 of the upper clamping plate portion 8 from above, the plurality of locations of the interview portion 13 are deformed so as to bulge downward, and the plurality of locations. The bulging deformation portion is the engagement protrusion 14 or a plurality of cut-out plate portions 12 of the upper clamping plate portion 8 are cut out downward to form the plurality of cut-out plate pieces as the engagement protrusions 14. It concerns on the installation fixture for roof installation of Claim 1 characterized by the above-mentioned.

  Since the present invention is configured as described above, when the overlapped plate portion for joining the roof plate material is clamped and clamped by the sandwiched portion, the interview portion of the upper sandwiched plate portion is in contact with a wide range of the upper surface of the joined overlapped plate portion. Therefore, it is difficult to cause deformation on the upper surface of the superposition plate portion for joining, and therefore, the upper surface of the superposition plate portion for joining of the roof plate material is not warped even when used for a stepped roof which is relatively easily deformed. It can be attached and fixed, and the interview portion of the present invention is composed of the lower surface of the bent tip plate portion formed by bending the tip portion of the upper clamping plate portion (metal plate material) into a substantially L shape. When the upper surface of the superposed plate portion is in contact, the plate spring action of the metal plate can be strongly pressed and fixed, and in addition, a plurality of engaging projections provided on the interview portion engage the upper surface of the superposed plate portion for bonding. Therefore, the sandwiching portion of the present invention can be firmly fixed to the superposed bonding plate portion, In addition, while the structure can be firmly fixed in this way, the engaging projection does not penetrate deeply into the upper surface of the bonding superposed plate portion because the interview portion comes into contact with the upper surface of the superposed bonding plate portion. The upper surface of the superposed plate portion is less likely to cause paint peeling, and is less likely to be rusted due to paint peeling, and in addition, the metal fitting body of the present invention is formed by bending a single metal plate material, for example, It can be easily manufactured by press working, etc., and it can be mass-produced at low cost because the amount of material used is small.

  In the invention according to claim 2, since the engaging projection that exhibits the above-mentioned action and effect can be integrally formed from the bent tip plate portion of the upper clamping plate portion, the engaging projection can be formed without cost. In addition, the engagement protrusion having this configuration can be easily manufactured by using a press or the like, so that the mass can be easily produced.

It is a perspective view which shows a present Example. It is a perspective view from another angle which shows a present Example. It is a disassembled perspective view of a present Example. It is a sectional side view which shows a present Example. It is a schematic explanatory perspective view which shows the use condition of a present Example. It is a partial expanded explanation side sectional view showing the use condition of this 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 metal fitting body A is disposed so as to sandwich the overlapping overlapping plate portion 2 of the roof plate material 1 of the side roof R between the upper sandwiching plate portion 8 and the lower sandwiching plate portion 9, and the upper sandwiching plate portion 8 and the lower sandwiching portion When the tightening bolt 10 installed between the plate portion 9 is turned and turned, or the nut 11 screwed to the tightening bolt 10 is turned and turned, the upper holding plate portion 8 and the lower holding plate portion 9 are , The sandwiching portion 3 (the upper sandwiching plate portion 8 and the lower sandwiching plate portion 9) clamps and sandwiches the joining overlapping plate portion 2, and the product of the present invention is on the side roof R Fixed to.

  At this time, the sandwiching portion 3 of the present invention bends the distal end portion of the upper sandwiching plate portion 8 in an L shape so that the surface contact portion 13 on the lower surface of the folded distal end plate portion 12 becomes the lower sandwiching plate portion 9. The upper clamping plate portion 8 is in contact with the upper surface of the superposition plate portion 2 for bonding, and the distal end plate portion of the lower clamping plate portion 9 is used for bonding. By contacting the lower surface of the overlapping plate portion 2, the bonding overlapping plate portion 2 is sandwiched.

  In addition, since the interview portion 13 has a length along the lateral direction of the joining superposed plate portion 2, it comes into contact with a wide range of the upper surface of the joining superposed plate portion 2. Therefore, the tightening force applied to the upper surface of the bonding superposition plate portion 2 from the interview portion 13 is distributed and applied over a wide range of the upper surface of the superposition polymerization plate portion 2, so that the interview portion 13 is joined to the superposition plate for bonding. The upper surface of the portion 2 does not bite deeply, and the upper surface of the joining superposed plate portion 2 is not easily deformed.

  Therefore, the mounting bracket can be mounted and fixed so as not to be deformed with respect to the superposed plate portion 2 of the roof plate material 1 for the stepped roof that is relatively easily deformed.

  At this time, the surface contact portion 13 is formed by bending the metal plate material 6 (the front end portion of the upper clamping plate portion 8) and the plate spring action of the bent front end plate portion 12 to help the joining superposed plate portion 2. In addition, the surface of the upper surface of the joining overlapped plate portion 2 is press-engaged with a plurality of engaging projections 14 provided at intervals in the length direction of the surface of the contacting portion 13. Therefore, a strong press-contacting action of the plurality of engaging protrusions 14 to the upper surface of the joining overlapping plate portion 2 is exhibited, and the clamping portion 3 is firmly fixed to the joining overlapping plate portion 2. Become.

  Further, since the interview portion 13 bites into the upper surface of the joining superposed plate portion 2 and does not engage with it, the upper surface of the joining superposed plate portion 2 is hardly peeled off, and the plurality of engaging protrusions 14 are also connected to the joining superposition plate 14. It is press-engaged with the upper surface of the plywood part 2, but the engaging projection 14 deeply bites into the upper surface of the superposed bonding plate part 2 because the interviewing part 13 is in contact with the upper surface of the superposing bonding plate part 2. Therefore, even if there is paint peeling on the upper surface of the joining superposed plate portion 2 when the mounting bracket is fixed, there is little.

  Therefore, the use of the mounting bracket is unlikely to cause rusting of the superposed bonding plate portion 2 of the roof plate material 1, and hardly deteriorates the durability of the roof plate material 1.

  By the way, the present applicant reinforces between the joining overlapping plate portions 2 of the roofing plate material 1 for the side roof R connected in parallel in the roof inclination direction in FIGS. 16 and 17 of Japanese Patent Application No. 2010-146228. There has been proposed an attachment method in which the joining overlapping plate portion 2 is reinforced by sandwiching the plates, and this kind of roof installation fixture is attached to the reinforced joining overlapping plate portion 2. And according to the attachment method which reinforces using such a reinforcement board, since the deformation | transformation more than necessary of the superposition | polymerization board part 2 for joining can be prevented even if it uses an attachment metal fitting like patent document 1, this method is also It is very effective for use on corrugated roofs.

  However, according to the present invention, since the reinforcing plate itself is unnecessary, it is sufficient to perform the conventional installation work without adding one effort such as sandwiching the reinforcing plate between the joining overlapping plate portions 2 when the roof plate material 1 is installed. The use of a reinforcing plate does not cause an increase in cost and is more practical.

  By using the upper mounting portion 5 of the main mounting bracket fixed on the side roof R (roof sheet material 1) in this way, a snow stopper, a solar panel 4A, a snow melting device, and their mounting tools 4B, etc. The on-roof installation 4 can be mounted on the side roof R.

  Further, the metal fitting body A of the present invention configured by bending a single metal plate 6 into a substantially U-shape can be easily manufactured by, for example, press working or the like, and has a bending portion having an interview portion 13. The tip plate portion 12 can be easily formed, and since the amount of material used is small, it can be mass-produced at a relatively low cost.

  Specific embodiments of the present invention will be described with reference to the drawings. In addition, the side roof R of drawing has shown the step roof R. FIG.

  In this embodiment, a snow stop fitting, a solar panel 4A, a snow melting device, and the like are provided on the upper part of a metal fitting body A provided with a holding portion 3 for holding and fixing the overlapping plate portion 2 for joining the roof plate material 1 of the stepped roof R. An attachment portion 5 to which the installation object 4 on the roof such as the attachment 4B can be attached is provided.

  Specifically, as shown in FIG. 1 and FIG. 2, the metal fitting body A of the present embodiment is formed by bending a single strip-shaped metal plate 6 into a substantially U-shape by pressing, thereby forming a back plate portion 7. The upper sandwiching plate portion 8 and the lower sandwiching plate portion 9 are configured in a shape in which the upper sandwiching plate portion 8 and the lower sandwiching plate portion 9 are continuously provided in the upper and lower ends at the upper and lower ends of the intermediate vertical plate portion.

  As shown in FIGS. 3 and 4, the clamping unit 3 of this embodiment is constructed by tightening a bolt 10 between the upper clamping plate 8 and the lower clamping plate 9 of the metal fitting body A. When a nut 11 is screwed onto the tip of the bolt 10 and the nut 11 is tightened and rotated, the back plate portion 7 is elastically deformed, and the facing interval between the upper clamping plate portion 8 and the lower clamping plate portion 9 is narrowed. Thus, the joining overlapping plate portion 2 of the roof plate material 1 can be clamped and fixed between the upper holding plate portion 8 and the lower holding plate portion 9. In other words, the U-shaped metal fitting body A, the fastening bolt 10 and the nut 11 constitute the clamping portion 3.

  More specifically, an insertion hole 15 through which the fastening bolt 10 can be inserted is formed through the upper clamping plate portion 8 and the lower clamping plate portion 9, and the upper clamping plate portion 8 is formed from below the lower clamping plate portion 9. A bolt tip portion of the tightening bolt 10 is inserted and installed in each insertion hole 15 so that the nut 11 is screwed onto the bolt tip portion of the tightening bolt 10 protruding upward from the upper clamping plate portion 8. Thus, the fastening bolt 10 is held in a state that prevents the metal fitting body A from falling off. Reference numeral 18 in the figure denotes a washer.

  Further, the cross-sectional shape of the base end portion of the tightening bolt 10 is formed in a square shape, while the insertion hole 15 of the lower holding plate portion 9 through which the square base end portion of the tightening bolt 10 is inserted is formed in a square hole. Then, when the rectangular base end portion of the tightening bolt 10 is inserted into the insertion hole 15 of the lower holding plate portion 9, the tightening bolt 10 is configured to be prevented from rotating with respect to the bracket body A, The rotation operation of the nut 2 can be easily performed above the metal fitting body A with respect to the tightening bolt 10 in the non-rotating state.

  Further, in the present embodiment, the front end portion of the upper holding plate portion 8 of the holding portion 3 is bent downward in a substantially L shape so that the lower surface of the bent front plate portion 12 and the lower holding plate portion 9 are The tip plate portion is provided in an opposing state.

  Specifically, as shown in FIG. 4, the tip end portion of the upper clamping plate portion 8 is bent downward at a substantially right angle, and the tip end portion of the depending bent portion 17 is further bent with respect to the depending bent portion 17. A bent tip that is bent at a substantially right angle (bends at a substantially right angle toward the back plate 7) and has a substantially L shape when the tip of the upper clamping plate 8 is viewed from the side. It is formed on the plate part 12.

  In addition, as shown in FIGS. 1 and 2, the bent front end plate portion 12 has a configuration in which the entire region in the left-right lateral width direction of the front end portion of the upper clamping plate portion 8 is bent in a substantially L shape. The lower surface of the bent front end plate portion 12 is configured to be continuous in a strip shape throughout the width direction of the upper clamping plate portion 8.

  Further, in this embodiment, the lower surface of the bent plate portion 12 of the bent end plate portion 12 is used as a surface contact portion 13 that makes a surface contact with the upper surface of the overlapping overlapping plate portion 2 of the roof plate material 1, and the surface contact portion 13 is the surface of the bonding portion 13. It is comprised so that it can interview along the horizontal direction of the superposition | polymerization board part 2. FIG. That is, the surface contact portion 13 is formed in a strip shape having a length along the horizontal direction of the bonding superposed plate portion 2.

  Further, in this embodiment, a plurality of engaging projections 14 are provided on the interview portion 13 so as to be engaged with the upper surface of the joining overlapping plate portion 2 at intervals in the length direction of the interview portion 13. .

  Specifically, by pressing a plurality of locations on the upper surface of the bent front end plate portion 12 of the upper clamping plate portion 8 from above, the plurality of locations of the interview portion 13 are deformed to bulge downward downward. The plurality of bulging and deforming portions are used as the engaging protrusions 14. That is, in the present embodiment, the engaging protrusion 14 is formed integrally with the interview portion 13.

  More specifically, the engaging projections 14 are formed at two locations on both end sides in the length direction of the interview portion 13, and the engaging projections 14 are formed as small projections with a small degree of protrusion from the interview portion 13. The structure is such that the upper surface of the superposed bonding plate portion 2 does not penetrate deeply.

  Although not shown, a configuration may be adopted in which a plurality of portions of the interview portion 13 are cut downward, for example, in a band shape, and the plurality of cutout plate pieces are used as the engagement protrusions 14.

  In addition, the mounting portion 5 of the present embodiment includes the fastening bolt 10 protruding upward from the upper clamping plate portion 8 of the metal fitting body A through the insertion hole 15 of the upper clamping plate portion 8. It consists of a bolt tip. That is, the fastening bolt 10 of the present embodiment is configured such that the bolt tip portion also functions as the attachment portion 5 of the roof installation object 4.

  In FIGS. 5 and 6, a solar panel mounting fixture 4B (on-roof installation 4) is attached to the bolt tip as the mounting portion 5 by using an installation fixture nut 16. The case where the solar panel 4A (installed object 4 on a roof) is attached on the side roof via the fixture 4B is shown.

  Further, in the metal fitting body A of the present embodiment, the upper holding plate portion 8 is opened upward with respect to the lower holding plate portion 9 in a normal state, and the tip plate portion of the lower holding plate portion 9 and the interview portion 13 are When the nut 11 is tightened and rotated, the back plate portion 7 is elastically deformed to form a lower clamping plate portion. 9 and the upper clamping plate 8 are narrowed. At this time, a return elastic force against the clamping force of the nut 11 is generated at the back plate 7 at the same time around the insertion hole 15 around the upper clamping plate 8. The upper surface is in pressure contact with the lower surface of the nut 11, and the lower surface around the insertion hole 15 of the lower clamping plate portion 9 is in pressure contact with the upper side of the bolt head of the bolt 10, and the upper clamping plate portion 8 and the nut 11 are pressed. So that the tightening bolt 10 and the nut 11 can be prevented from loosening by the pressure frictional force between the lower clamping plate 9 and the bolt head. It is configured.

  Further, in this embodiment, as shown in FIGS. 4 and 6, the cross-sectional shape of the back plate portion 7 is convex toward the inner side facing the lower holding plate portion 9 and the upper holding plate portion 8. It is formed in a curved cross-sectional shape.

  Specifically, the back plate portion 7 is viewed from the side in the entire width direction, and the back side of the back plate portion 7 (opposite of the side from which the upper holding plate portion 8 and the lower holding plate portion 9 protrude). It is formed in a cross-sectional curved shape that warps to the side. In other words, the back plate 7 is warped to the outside of the metal fitting body A (left side in FIG. 4).

  The curved back plate portion 7 is elastically deformed so that the nut 11 is tightened and rotated so that the upper plate 8 and the lower plate 9 are opposed to each other with a narrower gap. When this occurs, the return elastic force against this elastic deformation is always exhibited satisfactorily. Further, the warped burr-shaped back plate portion 7 is also prevented from projecting and deforming so that the back plate portion 7 swells outward from the metal fitting body A.

  That is, when the nut 11 is turned and tightened, if the back plate 7 protrudes and deforms so as to bulge outward from the bracket body A, the shape of the back plate 7 is directly applied to the return elastic force. However, in this embodiment, the back plate portion 7 does not lose the return elastic force because the cross-sectional curved shape (curved shape) of the back plate portion 7 is maintained, and this return elastic force is permanent. It is set as the structure which will be demonstrated in an effort. Therefore, due to the elastic force of the permanent back plate portion 7, the lower clamping plate portion 9 and the upper clamping plate portion 8 are always brought into pressure contact with the tightening bolt 10 and the nut 11 which have been tightened and rotated, and frictional resistance is generated. Therefore, a very good locking action of the tightening bolt 10 and the nut 11 can be obtained, and the tightening and fixing state by the clamping portion 3 can be ensured over a long period of time.

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