Description

  The present invention relates to a roof-mounted object fixing device for fixing a roof-mounted object such as a photovoltaic power generation panel to the roof.

  Solar power generation panels are often installed on the roof in ordinary households. Conventionally, when installing a photovoltaic power generation panel on a roof, a vertical beam extending in the flow direction of the roof and a horizontal beam extending in the row direction of the roof are combined in a cross beam shape, and solar power generation is performed on the vertical beam and the horizontal beam. The panel was fixed.

Japanese Patent No. 3328561

  However, in Patent Document 1, the base plate is fixed at a predetermined position in the flow direction of the roof. For this reason, the installation position of the column bolt fixed to the base plate is also limited to a predetermined position in the roof flow direction. Therefore, the pillar bolts could not be installed at any desired position in the flow direction of the roof. Therefore, the installation position of the photovoltaic power generation panel is also limited to a predetermined position in the flow direction of the roof, and the photovoltaic power generation panel cannot be installed at a desired arbitrary position in the flow direction.

Moreover, when the vertical beam was fixed to the base plate, the stress due to the screw fastening was concentrated locally on the base plate, and the installation strength of the photovoltaic power generation panel fixing device was insufficient.
The present invention has been made in view of such circumstances, and it is an object of the present invention to provide a roof-mounted object fixing device having a high installation strength in which a prop bolt can be installed at an arbitrary position in the flow direction of the roof.

  The present invention includes a base plate disposed on a roof material and fixed to a rafter, a head having a head fixed to the base plate, and a screw portion protruding from the base plate, and the roof of the column bolt on the screw portion. A mounting device for mounting on-roof objects fixed in a floating state from the material, and the column bolts are erected on the base plate so that the position of the roof in the flow direction can be adjusted. (Claim 1).

  According to the above configuration, the base plate is fixed to the rafter of the roof material. For this reason, the base plate is securely fixed to the rafter and has excellent installation strength.

  Moreover, the support | pillar bolt is standingly arranged by the baseplate so that the position of the flow direction of a roof can be adjusted. For this reason, the pillar bolt can be installed at an arbitrary position in the flow direction of the roof.

  Further, the gantry device is fixed to the threaded portion of the column bolt in a state of floating from the roof material. For this reason, no load is applied to the roofing material, and the gantry device is fixed to a rigid rafter. Accordingly, the installation strength of the on-roof object mounted on the gantry device is increased.

  On the upper side of the base plate, a pair of rails extending in the flow direction of the roof is projected, and a rail groove extending in the flow direction of the roof is formed between the pair of rails. The post bolt is inserted into the groove and the rail is clamped between the head and a nut screwed to the screw portion, and the head and the nut are tightened, whereby the post bolt is It is preferable to be fixed to the rail (claim 2).

  In this case, the pillar bolt can be securely fixed to the rail groove without the head of the pillar bolt coming out of the rail groove.

  A screw having a screw head protruding into the rail groove is screwed to a portion of the base plate facing both ends of the rail in the extending direction, and the screw head is screwed into the rail groove. It is preferable that the column bolt protrudes to a position where it interferes with the head portion, and the leg portion of the screw protrudes from the upper side to the lower side of the base plate and is screwed to the rafter (Claim 3).

  In this case, the screw head of the screw protrudes into the rail groove to a position where it interferes with the head of the support bolt. For this reason, even if the support bolt can slide in the rail groove, it can be prevented from coming off from both ends of the rail groove due to interference with the screw heads protruding into the rail groove.

  The base plate is fixed to the rafter at a position straddling a pair of upper roof material and lower roof material adjacent to each other in the flow direction of the roof, and an upper portion disposed on the upper roof material in the base plate And an upper spacer and a lower spacer made of a rubber material, respectively, are attached to the lower portion of the base plate disposed on the lower roof material, and the upper spacer and the lower spacer A water passage is formed between the upper spacer portion and the lower spacer portion, and an inclined portion for guiding the water flow downward is preferably formed at each of the upper spacer portion and the lower spacer portion. Item 4).

  An upper spacer and a lower spacer made of a rubber material are attached to the upper and lower sides of the lower surface of the base plate, respectively. The base plate is temporarily fixed to the roof material by the adhesive force of the rubber material. For this reason, with the base plate temporarily fixed to the roof material, the position adjustment of the column bolts and the screwing operation to the rafters with screws can be performed, and the workability on the roof is improved.

  Further, a drainage passage is interposed between the upper spacer and the lower spacer. Rainwater can pass through this drainage passage, and it is possible to prevent the rainwater flow from being retained by the base plate. Furthermore, the upper part of the upper spacer and the upper part of the lower spacer are each formed with an inclined part for guiding the water flow downward. For this reason, rainwater can be made to flow downward by the inclined portion without hitting the base plate and flowing backward to the upper side of the roof.

  The thickness of the lower spacer is preferably larger than the thickness of the upper spacer by the thickness of the upper roof material (Claim 5).

  The upper roof material is installed at a position higher than the lower roof material, and a step corresponding to the thickness of the upper roof material exists between the upper roof material and the lower roof material. This level difference is absorbed by making the thickness of the lower spacer larger than that of the upper spacer. For this reason, a base plate can be fixed stably.

  The gantry device is formed by combining a vertical beam extending in the flow direction of the roof and a horizontal beam extending in the crossing direction of the roof in a cross beam shape, and the horizontal beam is a horizontal beam stopper held by the vertical beam. The horizontal beam stopper is fixed to the vertical beam, and the horizontal beam stopper has an insertion part that passes through the vertical beam, and a holding member that protrudes from the insertion part and holds one side wall of the horizontal beam, A stopper having a pressing member disposed below the vertical rail, a locking piece for locking the other side wall of the horizontal rail facing the one side wall, and a fixing portion held on the insertion portion. And the fixing portion of the stopper member has an elongated hole extending in a direction to be separated from and coming into contact with the protruding piece, and the horizontal rail is formed by the locking piece of the stopper member and the protruding piece of the holding member. The bolt is formed in the elongated hole, the insertion portion, and the pressing member. The horizontal beam stopper by inserting the vertical beam between the fixed portion of the stopper member and the pressing member by inserting the vertical beam through the bolt hole and tightening the nut fixed to the pressing member. It is preferable that the horizontal beam is fixed to the vertical beam and the horizontal beam is fixed to the horizontal beam stopper.

  In this case, the vertical beam is sandwiched and pressed between the pressing member and the stop member by disposing the vertical beam between the pressing member and the stop member of the horizontal beam stopper and tightening with the bolt. For this reason, the horizontal beam stopper is securely fixed to the vertical beam. Moreover, since the horizontal rail is clamped by the protruding piece of the holding member and the locking piece of the stop member, the horizontal rail can be securely fixed to the horizontal stopper. Therefore, the vertical beam and the horizontal beam can be reliably assembled by the horizontal beam stopper.

  The roof mounted article fixing device of the present invention fixes the base plate to the rafter, and the column bolts are erected on the base plate so that the position of the roof in the flow direction can be adjusted. For this reason, a base plate can be reliably fixed to a rafter, and the installation intensity | strength of a mounted object fixing apparatus on a roof is high. Further, the support bolt can be installed at a desired position in the flow direction of the roof.

  In addition, the gantry device 3 is fixed to the threaded portion 2a of the column bolt 2 in a state of floating from the roof. For this reason, no load is applied to the slate 40, and the gantry device 3 is fixed to the rigid rafter 45. Therefore, the installation strength of the photovoltaic power generation panel 7 attached to the gantry device is increased.

  Further, by moving the level nut 23 screwed to the support bolt 2 in the vertical direction, the height of the gantry device 3 can be adjusted so that the load to each support bolt 2 is evenly applied. Therefore, while ensuring the rigidity of the gantry device 3, it is possible to absorb the planar non-uniformity of the slat 40 and ensure a uniform height of the photovoltaic power generation panel along the inclination direction of the base plate 44. .

  The column bolt 2 is inserted into the rail groove 13 of the base plate 1 and the rails 11 and 12 are sandwiched between the first nut 21 and the second nut 22 so that the column bolt 2 is fixed to the rails 11 and 12. For this reason, the column nut 2 can be securely fixed to the rails 11 and 12 without the first nut 21 of the column bolt 2 coming out of the rail groove 13.

  At both ends in the extending direction of the rail groove 13, the heads of the screws 14 b and 14 d protrude to a position where they interfere with the first nut 21 screwed into the column bolt 2 in the rail groove 13. For this reason, even if the support bolt 2 can slide in the rail groove 13, it interferes with the heads of the screws 14 b and 14 d at both ends of the rail groove 13. Therefore, it is possible to prevent the support bolt 2 and the first nut 21 screwed on the support bolt 2 from falling off from both ends of the rail groove 13.

  An upper spacer 15a and a lower spacer 15b made of a rubber material are attached to the upper and lower sides of the lower surface of the base plate 1, respectively. The base plate 1 is temporarily fixed to the upper and lower slate 41, 42 by the adhesive force of the rubber material. For this reason, in a state where the base plate 1 is temporarily fixed to the slate 40, the position adjustment of the column bolt 2 and the screwing work to the rafter 45 by the screws 14b, 14c, 14d, 14e, and 14f can be performed. Therefore, workability on the roof is improved.

  Further, as shown in FIG. 3, a drainage passage 16 is interposed between the upper spacer 15a and the lower spacer 15b. Rainwater can pass through the drainage passage 16 while flowing in the swaying direction Y on the slate 40. Therefore, it is possible to suppress the rainwater flow from being retained by the base plate 1.

  Furthermore, inclined portions 15c and 15d for guiding the water flow downward are formed on the upper portion of the upper spacer 15a and the upper portion of the lower spacer 15b, respectively. For this reason, rainwater can be made to flow downward by the inclined portions 15 c and 15 d without hitting the base plate 1 and flowing backward to the upper side of the roof.

  As shown in FIG. 5, the upper slate 41 is installed at a position higher than the lower slate 42, and a step corresponding to the thickness of the upper slate 41 exists between the upper slate 41 and the lower slate 42. To do. This level difference is absorbed by making the thickness of the lower spacer 15b thicker than that of the upper spacer 15a. For this reason, the base plate 1 can be fixed stably.

  As shown in FIG. 7, when the vertical beam 31 is disposed between the pressing member 36 and the stop member 37 of the horizontal beam stopper 33 and tightened with the bolt 38, the vertical beam 31 is moved by the pressing member 36 and the stop member 37. It is sandwiched and pressed. For this reason, the horizontal beam stopper 33 is securely fixed to the vertical beam 31. Further, since the horizontal beam 32 is sandwiched between the protruding piece 35 d of the holding member 35 and the locking piece 37 b of the stop member 37, the horizontal beam 32 can be reliably fixed to the horizontal beam stopper 33. Therefore, the vertical beam 31 and the horizontal beam 32 can be reliably assembled by the horizontal beam stopper 33.

  Further, the vertical beam 31 is made of an aluminum material, and a hollow portion is formed at the center, so that the rigidity in the cross-sectional direction is slightly weakened. For this reason, when a heavy load is applied in the cross-sectional direction, the vertical rail 31 is curved in an arch shape. Therefore, even if the shape of the roof is curved in an arch shape, the vertical rail 31 can be fixed along the shape.

  In the present embodiment, the photovoltaic power generation panel is installed on the slate using the gantry device 3, but the present invention can also be applied to the case where another on-roof placement object is installed on the roof.
