JP 2003-239471 A (paragraphs 0023 and 0024, FIG. 4)

  According to this prior art, in order to couple the rail member to the foundation structure, a nut into which the tip of the bolt is screwed must be arranged in the rail member. In addition, the position of the rail member that is a long member is set to a predetermined position with respect to the foundation structure, and the nut is arranged at the position of the rail member that matches the position of the bolt arranged on the foundation structure. For this reason, a lot of work and time are required for the work for coupling the rail member to the foundation structure.

  An object of the present invention is to provide an installation device for an installation on a roof that can easily perform an operation for connecting a rail member to a foundation structure with a small number of members.

  A mounting apparatus for an installation on a roof according to the present invention includes a foundation structure disposed on the roof, and a rail member that is coupled to the foundation structure by a coupling means and to which the installation on the roof is fixed. In the attachment device for a roof-mounted object, the coupling means is a bolt provided on the foundation structure so as to be capable of moving forward and backward toward the rail member, and the tip of the bolt advanced forward strongly pressurizes the rail member. The rail member is coupled to the foundation structure by deforming the rail member.

  In this attachment device, the rail member is coupled to the foundation structure by advancing the bolt provided on the foundation structure and deforming the rail member by the tip of the bolt strongly pressing the rail member. It is not necessary to arrange the nut into which the tip of the screw is screwed in the rail member, and therefore the number of members can be reduced. In addition, after the position of the rail member, which is a long member, is set to a predetermined position with respect to the foundation structure, the bolt is rotated to advance, and the forward end of the bolt strongly pressurizes the rail member by this advancement. Since the rail member can be coupled to the foundation structure by deforming the member, the operation of placing the nut into which the tip of the bolt is screwed can be omitted. The operation | work which couple | bonds a rail member can be performed easily.

  That is, according to the present invention, after the rail member is arranged at a predetermined position in the length direction of the rail member with respect to the foundation structure, the bolt is rotated and advanced, and the tip of the bolt is moved forward by this advancement. Since the rail member can be coupled to the foundation structure by applying strong pressure and deformation, the rail member can be easily coupled to the foundation structure at an arbitrary position of the rail member that is the predetermined position of the rail member. Can be combined.

  When the bolt is rotated and advanced, the advance may be stopped when the portion of the rail member with which the tip of the bolt abuts is deformed such as bulging, or the tip of the bolt It may be stopped when the portion of the rail member in contact with is damaged after undergoing deformation such as bulging. That is, the forward movement of the bolt may be performed until the portion of the rail member with which the front end of the bolt abuts is damaged.

  Further, in the mounting device according to the present invention, when the rail member is coupled to the foundation structure by deforming the rail member by the tip of the bolt strongly pressing the rail member, the rail member is combined with the foundation structure. You may provide the pressing member for pressing down and making it a fixed state.

  When such a pushing member is provided in the mounting device, when the tip of the bolt strongly presses the rail member to deform the rail member, the rail member is pushed up and down by the foundation structure and the pushing member. Since the rail member is fixed in the vertical direction, when the tip of the bolt strongly presses the rail member to deform the rail member, the deformation can be surely performed. The rail member can be more securely coupled to the rail.

  When the pushing member is provided in the mounting device in this way, as an example, a bolt is inserted into the pushing member, and the pushing member is moved toward the rail member by moving the bolt forward, whereby the pushing member is moved to the rail. The member may be pressed up and down together with the foundation structure to be in a fixed state.

  According to this, when the bolt is advanced to connect the rail member to the foundation structure, the pushing member moves to the rail member side by the advance of the bolt, and the rail member is pushed up and down together with the foundation structure. In order to achieve a fixed state, the rail member is pressed up and down by the pushing member and the foundation structure to be in a fixed state, and the rail member is coupled to the foundation structure by one operation of advancing the bolt. As a result, workability is improved.

  Further, the basic structure of the mounting device according to the present invention is provided with a receiving member for receiving the rail member from below, and the receiving member is provided with a pair of uprights rising on both sides in the width direction of the rail member. And a screw hole into which the bolt is screwed toward the rail member.

  According to this, since the said bolt is provided in each of a pair of said upright part of a receiving member, the location where a rail member is couple | bonded with a foundation structure with a volt | bolt may be made into two places of the width direction both sides of a rail member. This allows the rail member to be more reliably coupled to the foundation structure.

  Further, in the present invention, a plurality of rail members are provided in a direction orthogonal to the flow direction of the roof (the gradient direction of the roof), and each rail member has a length extending in the flow direction of the roof. In the case where a plurality of the foundation structures are arranged in the length direction of the rail member for each rail member, at least one foundation structure per one rail member among these foundation structures is provided with a rail member. There may be provided a slide blocking means for preventing the slide from sliding downward in the flow direction of the roof.

  According to this, when each rail member is coupled to the foundation structure by the strong pressure and deformation of the rail member using the above-described bolts, the rail member is subject to its own weight or installation on the roof even if the coupling strength is insufficient. It is possible to prevent the slide from being slid downward in the flow direction of the roof due to the weight of the slide.

  An example of the slide preventing means in the case where such a slide preventing means is provided in the mounting device according to the present invention is to use a rod-like member that penetrates the rail member and is fixed to the foundation structure. In this way, when the slide blocking means is a rod-shaped member that passes through the hole formed in the rail member and is fixed to the foundation structure, the hole formed in the rail member is formed in the length direction of the rail member. It is good also as a long hole formed long.

  According to this, even if the rod-shaped member fixed to the foundation structure is passed through the hole formed in the rail member, this hole is a long hole formed long in the length direction of the rail member. Before the rail member is coupled to the foundation structure by the bolt, it is possible to adjust the position of the rail member in the length direction of the rail member with respect to the foundation structure by the length of the long hole. Become.

  Such position adjustment of the rail members is performed, for example, when the positions of the end portions of the respective rail members are aligned and these rail members are disposed on the roof.

  The rod-shaped member may be a pin such as a spring pin, a bolt, or any rod-shaped member.

  In the present invention, the rail member may be arranged such that the length direction of the rail member is the flow direction of the roof, or the direction in which the length direction of the rail member is orthogonal to the flow direction of the roof ( It may be a member arranged in the direction of the roof's beam).

  Moreover, the attachment device according to the present invention may use a rail member that is arranged with the flow direction of the roof in the length direction, and a rail member that is arranged with the crossing direction of the roof in the length direction. .

  Further, the roof to which the mounting device according to the present invention is applied may be a tiled roof in which the roof finishing material is a tile, a slate thatched roof in which the roof finishing material is a slate, and an arbitrary roof finishing material. The mounting device according to the present invention can be applied to the used roof.

  In addition, disposing the foundation structure on the roof may be connecting the foundation structure to the roof finishing material, or a roof base material such as a rafter or a base plate arranged under the roof finishing material. It is also possible to connect the base portion of the foundation structure and project at least the remaining part of the foundation structure through the roof finishing material and project on the roof finishing material.

  Furthermore, the on-roof installation installed on the roof by the mounting device according to the present invention may be a solar panel for solar power generation, a water heater, or a roof signboard, and the present invention may be used on any roof. It can be applied to installations.

  According to the present invention, it is possible to obtain an effect that the work for coupling the rail member to the foundation structure can be easily performed with a small number of members.

The side surfaces of the individual substructures 12 are shown enlarged. FIG. 5 is an exploded perspective view of the foundation structure 12.

  As can be seen from FIG. 2, each foundation structure 12 has the same structure, and as can be seen from FIGS. 3 to 5, each foundation structure 12 includes the tiled roof 1. Among the many roof tiles 2 formed, the first bracket member 13 coupled to the predetermined roof tile 2A, the second bracket member 14 coupled to the first bracket member 13, and the rail member 11 are arranged from the lower side. The receiving member 15 for receiving and the two pushing members 16 arranged on both side surfaces of the receiving member 15 are configured.

The first bracket member 13 has a U-shape that is downwardly opened and includes a base portion 13A that is parallel to the roof 1 and a pair of extending portions 13B that extend downward from both ends of the base portion 13A in the roof flow direction. It is a member. The second bracket member 14 extends downward from both the base portion 14A placed on the upper surface of the base portion 13A of the first bracket member 13 and both ends of the base portion 14A in the direction orthogonal to the roof flow direction. A U-shaped member having a pair of extending portions 14B and opening downward is provided. The base portions 13A and 14A of the first and second bracket members 13 and 14 are formed with holes for inserting the shaft portion 17A of the bolt 17 upward into the base portions 13A and 14A. The first bracket member 13 and the second bracket member 14 are joined by screwing and tightening the nut 18 to the tip of the shaft portion 17A protruding upward from the upper surface of the base portion 14A of the two bracket members.

Moreover, as shown in FIG. 4, among the many tiles 2 forming the tiled roof 1, the tile 2 </ b> A in which the foundation structure 12 is arranged is arranged in parallel in the flow direction of the roof 1. A pair of upright portions 19 is provided, and the extension portion 13B of the first bracket member 13 is coupled to the upright portions 19 with bolts 20 and nuts 21, whereby the first bracket member 13 is coupled to the roof tile 2A. In addition, the foundation structure 12 is disposed on the tiled roof 1. Therefore, the 1st bracket member 13 in this embodiment is a member used as the base part couple | bonded with the tiled roof 1 among the members which comprise the foundation structure 12. FIG.

As shown in FIG. 5, the base portion 13 </ b> A of the first bracket member 13 is formed with a pair of protrusions 13 </ b> C that abut on both end surfaces of the base portion 14 </ b> A of the second bracket member 14 in the roof flow direction. Therefore, the protrusions 13 </ b> C prevent the second bracket member 14 from shifting in the flow direction of the roof 1 with respect to the first bracket member 13. Further, as shown in FIG. 3, the hole formed in the extending portion 13 </ b> B of the first bracket member 13 for inserting the shaft portion 20 </ b> A of the bolt 20 is in a direction orthogonal to the flow direction of the roof 1. A long slot 22 is formed. For this reason, the position where the first bracket member 13 is coupled to the tile 2A, in other words, the position where the foundation structure 12 is disposed on the tiled roof 1 can be adjusted in a direction perpendicular to the flow direction of the roof 1. It has become.

As shown in FIG. 5, the receiving member 15 described above includes a base portion 15A that is parallel to the roof 1, and a pair of hangers that hang downward from both ends of the base portion 15A in a direction orthogonal to the roof flow direction. It is a substantially H-shaped member composed of a portion 15B and a pair of upright portions 15C rising upward from the vicinity of both ends in the direction orthogonal to the roof flow direction in the base portion 15A. As can be seen from FIG. 3, each drooping portion 15 </ b > B is coupled to the extending portion 14 </ b > B of the second bracket member 14 with a bolt 23 and a nut 24, whereby the receiving member 15 is connected to the base portion 15 </ b> A of the receiving member 15.

As shown in Figure 5, received and the base unit 1 5 A member 15 is formed a large hole 25, binding Therefore, the receiving member 15 by bolts 23 and nuts 24 to the second bracket member 14 Even so, the shaft portion 17A of the bolt 17 and the nut 18 screwed to the shaft portion 17A can be prevented from interfering with the base portion 15A of the receiving member 15.

  As shown in FIG. 4, the hole formed in the hanging portion 15 </ b> B of the receiving member 15 for inserting the shaft portion 23 </ b> A of the bolt 23 described above is a long hole 26 that is long in the vertical direction. For this reason, the height position of the receiving member 15 with respect to the second bracket member 14 can be adjusted in the vertical direction.

  Further, as shown in FIGS. 3 and 5, each raised portion 15 </ b> C of the receiving member 15 tapers outward in the width direction of the receiving member 15, in other words, outward in the width direction of the rail member 11. A protruding portion 30 protruding in a shape is formed, and the pushing member 16 described above is disposed on the outer surface of the protruding portion 30. In the pushing member 16 in which the concave portion 16A having a shape corresponding to the protruding portion 30 is formed, the hole 32 into which the shaft portion 31A of the bolt 31 used for coupling the rail member 11 to the receiving member 15 is inserted (see FIG. 5) is formed. Further, as shown in FIG. 5, a screw hole 33 into which the shaft portion 31 </ b> A of the bolt 31 is screwed is formed in the raised portion 15 </ b> C of the receiving member 15.

  Further, each pushing member 16 is formed with holes 34 and 35 on both sides of the hole 32, that is, on both sides in the roof flow direction with respect to the hole 32. Holes 36 and 37 corresponding to 35 are formed.

As illustrated in FIG. 1, the mounting device 10 according to this embodiment includes two rail members 11 arranged in a direction orthogonal to the flow direction of the roof 1, and a rail member for each rail member 11. 11 and three base structures 12 arranged in the length direction, and each rail member 11 has three pieces arranged below the rail member 11. The receiving member 15 of the foundation structure 12 is disposed from above between the pair of upright portions 15C of the receiving member 15, and as can be seen from FIG. The rail member 11 is placed on the upper surface of the base portion 15A of each receiving member 15 whose direction dimension is short. The base portion 15A is formed with a pair of ridge portions 39 that are fitted to concave portions 38 (see FIG. 3) that are formed in a direction perpendicular to the roof flow direction on the lower surface of the rail member 11 . Therefore, the rail member 11 is positioned in a direction orthogonal to the roof flow direction with respect to the receiving member 15 by arranging the rail member 11 between the pair of upright portions 15C of the receiving members 15.

  Further, as shown in FIG. 3, protrusions 40 are formed on the side surfaces on both sides in the width direction of the rail member 11 so as to be fitted to the upper end of the upright portion 15 </ b> C of the receiving member 15. The pressing member 16 is provided with a pressing portion 41 for pressing the upper surface of the protruding portion 40.

  As shown in FIG. 3, a recess 11 </ b> A having an upward depth is provided on the lower surface of the rail member 11. Therefore, as described above, even if the height position of the receiving member 15 with respect to the second bracket member 14 is adjusted in the vertical direction by the long hole 26 formed in the hanging portion 15B of the receiving member 15, the first bracket The shaft member 17A and the nut 18 of the bolt 17 that joins the member 13 and the second bracket member 14 and protrudes upward from the large hole 25 of the base portion 14A of the second bracket member 14 are formed on the rail member 11. There is no interference with the lower surface. In other words, reducing the height position of the receiving member 15 relative to the second bracket member 14 until the lower surface of the base portion 15A of the receiving member 15 contacts the upper surface of the base portion 14A of the second bracket member 14 is to reduce the rail member 11. This is made possible by the recess 11A.

  In order to connect the rail member 11 to the receiving member 15, the shaft portion 31A of the bolt 31 described above is inserted into the hole 32 of the pushing member 16, and the shaft portion 31A is received from below the rail member 11 Then, the screw member 33 is screwed into the screw hole 33 provided in the upright portion 15C of the receiving member 15 so as to be able to advance and retract toward the rail member 11, and further, the bolt 31 is rotated to move the bolt 31 toward the rail member 11. When advanced, as shown in FIG. 3, the tip of the shaft portion 31 </ b> A is formed on the side surface 11 </ b> B of the rail member 11 that is an extruded product or a pultruded product made of aluminum or aluminum alloy. By strongly pressing the portion 42 corresponding to the tip, the portion 42 is bulged and deformed inside the rail member 11. As a result, the rail member 11 is coupled to the receiving member 15 by a large frictional force between the tip of the shaft portion 31A of the bolt 31 and the portion 42 of the rail member 11.

  Further, as described above, when the bolt 31 is advanced to connect the rail member 11 to the receiving member 15, the head portion 31 </ b> B of the bolt 31 pushes the pushing member 16 toward the rail member 11. The concave portion 16 </ b> A described above is fitted to the protruding portion 30 formed in a tapered shape on the outer side in the width direction of the receiving member 15 on the rising portion 15 </ b> C of the receiving member 15, and the pressing portion 41 provided on the pressing member 16 is provided. In order to press the upper surface of the protrusion 40 formed on the side surface 11B of the rail member 11, the rail member 11 is pressed up and down by the pressing member 16 and the base portion 15A of the receiving member 15. The rail member 11 is fixed in a fixed state in the vertical direction.

  Thus, when the rail member 11 is pressed up and down by the pressing member 16 and the base portion 15A of the receiving member 15 and is fixed in the vertical direction, the tip of the shaft portion 31A of the bolt 31 is the rail member. 11, the portion 42 corresponding to the tip of the shaft portion 31 </ b> A is strongly pressurized, and the strong pressure causes the portion 42 to bulge and deform inside the rail member 11. This bulging deformation required for the coupling can be realized with certainty, whereby the rail member 11 can be reliably coupled to the receiving member 15.

  The operation of moving the bolt 31 forward may be stopped after the portion 42 is bulged and deformed before the portion 42 is damaged, or after the portion 42 is bulged and deformed, You may continue until it breaks.

  As shown in FIGS. 3 and 4, the rail member 11 is provided with bolts 50 for fixing the solar panel 3 described above to the rail member 11. The bolt 50 is a bolt with a head portion 50 </ b> A. The head portion 50 </ b> A is inserted into a groove 51 provided at the upper portion of the rail member 11, and the shaft portion 50 </ b> B of the bolt 50 is formed at the upper portion of the groove 51. The pair of protrusions 52 formed in the width direction of the rail member 11 extends upward from the rail member 11 through a gap 53. The groove 51 and the gap 53 are formed continuously over the entire length of the rail member 11. By tightening the nut 54 screwed into the shaft portion 50 </ b> B of the bolt 50 against the upper surface of the projecting portion 52, the bolt 50 is attached to the rail member 11 at an arbitrary position in the length direction of the rail member 11. Combined.

  The bolt 50 is a T-shaped bolt as shown in FIG. 6, which is an exploded perspective view of the rail member 11 and the bolt 50. That is, the planar shape of the head portion 50A of the bolt 50 is a rectangle or a substantially rectangular shape having a short dimension L1 and a long dimension L2. The short dimension L1 is smaller than the dimension L3 of the gap 53 of the rail member 11, and the long dimension L2 is smaller than the dimension L4 of the groove 51 and larger than the dimension L3 of the gap 53.

  For this reason, in this embodiment, in order to arrange the bolt 50 at a predetermined position in the length direction of the rail member 11, the head portion 50A is inserted into the groove 51 from one end portion in the length direction of the rail member 11. Thus, it is not necessary to slide the bolt 50 to a predetermined position on the rail member 11. That is, in this embodiment, in order to arrange the bolt 50 at a predetermined position in the length direction of the rail member 11, as shown in FIG. 6 above the predetermined position of the rail member 11, After the direction of the head 50A coincides with the length direction of the rail member 11, in other words, after the direction of the long dimension L2 and the length direction of the rail member 11 are made parallel, the bolt 50 is lowered as it is. The head 50A is allowed to pass through the gap 53 to reach the groove 51, and then the head 50A is locked to the groove 51 by rotating the bolt 50 about the shaft portion 50B by 90 degrees. Thereafter, the nut 54 is brought into contact with the upper surface of the protrusion 52 and further tightened, whereby the bolt 50 can be coupled to the rail member 11 at a predetermined position in the length direction of the rail member 11.

  In the present embodiment, as shown in FIG. 2, three such bolts 50 are provided for each rail member 11, and one such bolt 50 and one rail member 11 are provided. The two solar panels 3 shown in FIG. 1 are fixed to the rail member 11 by the fixing member 61 prepared individually and the two fixing members 62 prepared per one rail member 11. It is like that. As shown in FIG. 2, a pair of fixing members 61 are formed in the roof flow direction on the bottom surface of the base portion 61 </ b> A in which the shaft portion 50 </ b> B of the bolt 50 penetrates vertically, and on the bottom surface of the base portion 61 </ b> A. Leg portions 61B and 61C placed on the upper surface of the member 11, and a pressing portion for rising from one end portion of the base portion 61A in the roof flow direction, contacting the upper surface of the solar panel 3, and pressing the solar panel 3 against the rail member 11 61D.

The parts 62B and 62C and the pressing parts 62D and 62E for rising from both ends of the base 61A in the roof flow direction, contacting the upper surface of the solar panel 3 and pressing the solar panel 3 against the rail member 11 are formed.

  The fixing member 61 is an end on the upper end side of each rail member 11 arranged on the roof 1 with the same inclination angle as the gradient of the roof 1 by the foundation structure 12 described above, that is, the ridge of the roof 1 in the rail member 11. At the end of the side. One of the two fixing members 62 is arranged at an intermediate position in the length direction of the rail member 11 between the two solar panels 3. The other one fixing member 62 is arranged at the lower end side end of each rail member 11, that is, the eaves side end portion of the roof 1 in the rail member 11. The fixing members 61 and 62 are coupled to the rail member 11 by further tightening the nuts 63 screwed into the shaft portions 50B of the bolts 50 with the base portions 61A and 62A of the fixing members 61 and 62 being further tightened. .

  Thus, by performing the operation | work which couple | bonds each fixing member 61 and 62 with the rail member 11 by the nut 63, roof flow is carried out by the pressing part 61D of the fixing member 61 arrange | positioned at the edge part of the upper end side of the rail member 11. Of the two solar panels 3 arranged side by side, the upper end of the upper solar panel 3 is pressed against the rail member 11 side, and the fixing member 62 arranged at the intermediate position in the length direction of the rail member 11 Of the two solar panels 3, the lower end of the upper solar panel 3 and the upper end of the lower solar panel 3 are pressed against the rail member 11 side by the pressing portions 62 </ b> D and 62 </ b> E. The lower end of the lower solar panel 3 is pressed against the rail member 11 by the pressing portion 62E of the fixing member 62 arranged at the end on the side.

  As a result, each solar panel 3 is fixed to the rail member 11 by the bolt 50, the nut 63, and the fixing members 61 and 62.
