A method of attaching the fixture 10 to the roof 100 will be described with reference to FIGS. 4 to 9. The method of attaching the attachment 10 to the roof 100 includes a plurality of steps. The plurality of steps include a first opening forming step, a second opening forming step, an elastic member arranging step, a mounting member insertion step, a sealing agent filling step, a coating step, and a mounting step.

In the first opening forming step, as shown in FIGS. 4 and 5, a first opening 111 centered on a predetermined point P of the roofing material 110 is formed on the roofing material 110. The means for forming the first opening 111 is executed by any means. An example of any means is high speed rotation of a drill provided in a power tool. The shape of the first opening 111 is circular.

The first opening 111 is configured as a through hole connecting the first main surface 110A and the second main surface 110B of the roofing material 110. The diameter of the first opening 111 is set according to the diameter of the bolt 31 of the mounting member 30 and the thickness of the roofing material 110. For example, the diameter of the first opening 111 is the peripheral surface of the bolt 31, the lower surface of the plate member 40, the upper surface of the base material 120, and the first opening of the roof material 110 in the cross section along the central axis of the bolt 31. The area surrounded by the inner surface 111A of 111 is set to be formed in a square shape. The diameter of the first opening 111 is the total value of the diameter of the bolt 31 and the value obtained by doubling the thickness of the roofing material 110. For example, when the diameter of the bolt 31 is 8 mm and the thickness of the roofing material is 12 mm, the diameter of the first opening 111 is 32 mm.

In the second opening forming step shown in FIG. 6, the second opening 121 centered on the predetermined point P is formed on the base material 120 as in the case of the first opening 111. The means for forming the second opening 121 is executed by any means. An example of any means is high speed rotation of a drill provided in a power tool. The shape of the second opening 121 is circular.

The second opening 121 is formed so as to penetrate the base material 120 and connect the first main surface 120A and the second main surface 120B of the base material 120. The diameter of the second opening 121 is set to be larger than the diameter of the bolt 31 of the mounting member 30 and to a size that allows the locking tool 33 to be locked. In one example, the diameter of the second opening 121 is set to a value of 8 mm or more and 10 mm or less. The diameter of the second opening 121 is smaller than the diameter of the first opening 111.

In the elastic member arranging step, the elastic member 50 is arranged in the gap portion S formed between the roofing material 110 and the base material 120 in the first opening 111 of the roofing material 110. The elastic member 50 separates the gap S from the filling region F. In this embodiment, the elastic member 50 is an O-ring made of rubber. The diameter of the O-ring is larger than the diameter of the first opening 111. The diameter of the cross section of the O-ring is set according to the length of the gap S in the height direction. The elastic member 50 is deformed so that the cross-sectional shape is crushed by being sandwiched between the roof material 110 and the base material 120.

In the mounting member insertion step shown in FIG. 7, the bolt 31 of the mounting member 30 is inserted into the first opening 111 and the second opening 121. When the bolt 31 is inserted through the second opening 121, the main body 33A is rotated around the rotation center shaft 33B so that the locking tool 33 is along the bolt 31. This makes it possible to pass the locking tool 33 through the insertion hole 23 of the mounting plate 20 and the second opening 121 of the base material 120. After inserting the locking tool 33, the locking tool 33 rotates about the rotation center shaft 33B. The locking tool 33 is arranged so that the central axis of the locking tool 33 intersects the central axis of the bolt 31, and comes into contact with the second main surface 120B of the base material 120. At this time, the locking tool 33 is caught by the base material 120, and the bolt 31 is maintained so as not to be pulled back in the direction opposite to the insertion direction. In this way, after the bolt 31 is inserted, the locking tool 33 prevents the bolt 31 from coming out of the second opening 121. The mounting member insertion step may be performed with the plate member 40 mounted on the bolt 31. Further, the plate member 40 may be attached to the bolt 31 after the attachment member insertion step is performed. At this time, the plate member 40 is arranged so that the inner surface 111A of the first opening 111 and the engaging surface of the claw 43A are in contact with each other.

In the sealing agent filling step shown in FIG. 8, the sealing agent 60 is injected into the filling region F from the injection port 42 of the plate member 40. The sealing agent 60 is filled in the filling region F via, for example, a tube T configured to become thinner toward the tip from a container (not shown). In another example, the sealant 60 is filled directly into the filling region F from a container (not shown). Filling of the sealing agent 60 is performed, for example, to the extent that the sealing agent 60 flows out from the hole 43B of the injection port 42 or the engaging portion 43.

In the coating step, the waterproof sheet 70 is coated on the first main surface 41A of the plate member 40. The sheet 70 is, for example, butyl tape. The sheet 70 is adhered to the first main surface 41A of the plate member 40 and the first main surface 110A of the roofing material 110. The sheet 70 is provided with a hole for passing the mounting member 30.

In the mounting process, the mounting plate 20 is mounted on the plate member 40 by the nut 32. Specifically, after arranging the mounting plate 20 on the plate member 40, the nut 32 is attached to the bolt 31 and the nut 32 is tightened with a spanner. The distance between the nut 32 and the locking tool 33 is adjusted in the longitudinal direction of the bolt 31 so that the axial force becomes an appropriate magnitude. As a result, the mounting plate 20, the sheet 70, the plate member 40, the roofing material 110, and the base material 120 are sandwiched by the nut 32 and the locking tool 33 with an appropriate force.

The operation of the fixture 10 of the present embodiment will be described.
The mounting plate 20 is mounted on the roof 100 via the plate member 40. When the roofing material 110 is deformed by an external force, the plate member 40 may be displaced with respect to the roofing material 110, and a gap may be formed between the plate member 40 and the roofing material 110. In this respect, in this embodiment, the plate member 40 engages with the roofing material 110 by the engaging portion 43 of the plate member 40. As a result, when the roofing material 110 is deformed by an external force, the plate member 40 is less likely to be displaced with respect to the roofing material 110. This suppresses the formation of a gap between the roof material 110 and the plate member 40.

Further, in the present embodiment, the roofing material 110 is provided with a first opening 111 filled with the sealing agent 60. The plate member 40 is configured to cover the first opening 111. By engaging the engaging portion 43 of the plate member 40 with the first opening 111, the plate member 40 is positioned so as to cover the first opening 111. The plate member 40 is attached to the roofing material 110 by the fixture 10, and the first opening 111 is filled with the sealing agent 60. The plate member 40 engages with the first opening 111 of the roofing material 110. The engagement between the plate member 40 and the first opening 111 makes it difficult for the first opening 111 to be deformed. Therefore, even when the roofing material 110 is deformed by an external force, the deformation of the shape of the first opening 111 is suppressed, and the distortion of the sealing agent 60 is also suppressed. In this way, the formation of a gap between the roofing material 110 and the plate member is suppressed, and the watertightness is improved.

The effect of the fixture 10 of the present embodiment will be described.
(1) The mounting tool 10 includes a mounting plate 20, a mounting member 30, and a plate member 40 provided between the mounting plate 20 and the roofing material 110. The plate member 40 includes at least one engaging portion 43 for engaging with the roofing material 110. According to this configuration, the mounting plate 20 is mounted on the roof 100 via the plate member 40. The plate member 40 engages with the roofing material 110 by the engaging portion 43 of the plate member 40. As a result, when the roofing material 110 is deformed by an external force, the plate member 40 is less likely to be displaced with respect to the roofing material 110. In this way, the formation of a gap between the roof material 110 and the plate member 40 is suppressed, and the watertightness is improved.

(2) The plurality of engaging portions 43 are arranged along the peripheral edge of the first opening 111 formed in the roof material 110 when the plate member 40 is arranged on the roof material 110. It is configured to be. According to this configuration, the position of the plate member 40 can be easily positioned. Further, the side slip of the plate member 40 can be suppressed with respect to the roof 100.

(3) When the plate member 40 is arranged on the roofing material 110, the engaging portion 43 is configured such that the engaging surfaces of the plurality of claws 43A and the inner surface 111A of the first opening 111 come into contact with each other. May be done. When a force acts on the mounting plate 20 and the plate member 40 in the horizontal direction, lateral displacement of the mounting plate 20 and the plate member 40 may occur. Conventionally, in order to suppress such lateral displacement, the mounting plate 20 and the plate member 40 have been fixed with screws for preventing lateral displacement. According to the above configuration, since the plate member 40 engages with the roofing material 110 in the horizontal direction, such a screw can be omitted. In addition, the man-hours and materials required for mounting the fixture 10 can be reduced, and the elements that may allow water to infiltrate are reduced, so that the watertightness is improved.

(4) In the fixture 10, the plate member 40 further includes an injection port 42 for filling the sealing agent 60. According to this configuration, the sealing agent 60 can be easily filled.

(5) In the fixture 10, the shape of the plate member 40 is hexagonal in a plan view. With this configuration, for example, when the plate member 40 is rotated by a spanner to change the position with respect to the bolt 31, the plate member 40 can be easily rotated.

(6) The elastic member 50 is arranged in the gap S between the roofing material 110 and the base material 120 in the first opening 111 of the roofing material 110. The watertightness is improved by forming the filling region F in which the gap S is closed by the elastic member 50. Further, when the device is arranged on the fixture 10, the elastic member 50 is deformed under the load of the device. By arranging the elastic member 50 in the gap portion S, the deformation of the roofing material 110 is suppressed. As a result, it is possible to prevent a gap from being generated between the inner surface 111A of the first opening 111 of the roofing material 110 and the sealing agent 60 in the filling region F due to the deformation of the roofing material 110. Therefore, the watertightness can be suitably maintained.

(7) The opening area of the second opening 121 is smaller than the opening area of the first opening 111. As a result, the movement of the bolt 31 is restricted by the second opening 121. Therefore, the movement of the bolt 31 with respect to the external force acting on the base material 120 is suppressed, so that the watertight effect is suitably maintained.

(8) The fixture 10 may be configured so that the lengths of the first distance L1 and the second distance L2 are substantially equal in the filling region F. In this case, in the cross section along the central axis of the bolt 31, the region surrounded by the bolt 31, the plate member 40, the base material 120, and the inner surface 111A of the first opening 111 of the roofing material 110 is a square or a rectangle close to a square. Is formed in. Therefore, the volume in which the sealing agent 60 is filled is secured. Further, when the first external force acts on the bolt 31, the sealing agent 60 follows the bolt 31, so that the force is suppressed from acting on a specific portion. As a result, a gap is less likely to occur between the sealing agent 60 and the bolt 31, or between the sealing agent 60 and the inner surface 111A of the first opening 111 of the roofing material 110, and the watertight effect is maintained.

(9) The mounting method of the fixture includes a first opening forming step, a second opening forming step, an elastic member arranging step, a mounting member insertion step, a sealing agent filling step, and a mounting step. In the elastic member arranging step, the elastic member 50 is arranged in the gap portion S formed between the roofing material 110 and the base material 120 in the first opening 111 of the roofing material 110. In the sealing agent filling step, the sealing agent 60 is filled into the filling region F surrounded by the inner surface 111A of the plate member 40, the first opening 111 of the roofing material 110, and the base material 120 from the injection port 42 of the plate member 40. According to this configuration, the elastic member 50 is arranged in advance in the gap S before filling the sealing agent 60. When the elastic member 50 is not arranged in the gap portion S, the gap portion S may not be completely closed when the filling region F is filled with the sealing agent 60, but the elastic member 50 is arranged in the gap portion S in advance. As a result, it is possible to prevent the gap portion S from being blocked. In this way, the watertightness can be improved.

(10) In the mounting method of the fixture 10, the length between the inner surface 111A of the first opening 111 of the roofing material 110 and the peripheral surface of the bolt 31 in the cross section of the filling region F along the central axis of the bolt 31. The second distance L2 is preferably longer than half the length of the first distance L1, which is the thickness of the roofing material 110.

When the second distance L2 is shorter than half the length of the first distance L1, when the bolt 31 is pulled in the axial direction, the shearing force acting on the contact portion between the bolt 31 and the sealing agent 60 causes the sealing agent 60 from the bolt 31. May peel off. Further, when the second distance L2 is shorter than half the length of the first distance L1, when the bolt 31 is pulled in the axial direction, the sealing agent 60 is pulled together with the bolt 31, and the sealing agent 60 and the roofing material 110 are first pulled. The sealing agent 60 may be peeled from the first opening 111 due to the shearing force acting on the contact portion with the opening 111. In this respect, according to the above configuration, when the bolt 31 is pulled in the axial direction, the sealing agent 60 is moved along with the movement of the bolt 31 as compared with the case where the second distance L2 is shorter than half the length of the first distance L1. It becomes sufficiently deformable, and the shearing force acting on the contact portion between the bolt 31 and the sealing agent 60 and the shearing force acting on the contacting portion between the sealing agent 60 and the first opening 111 of the roofing material 110 become smaller. By such an action, peeling is suppressed at these contact portions. In this way, it is possible to suppress the formation of a gap between the contact portion between the bolt 31 and the sealing agent 60 and the contact portion between the sealing agent 60 and the first opening 111 of the roofing material 110.

(11) In the mounting method of the mounting tool 10, a covering step of covering the plate member 40 with the waterproof sheet 70 is further included. According to this configuration, the watertightness is further improved.
(12) In the mounting method of the mounting tool 10, the sealing agent 60 is injected into the first opening 111 from the injection port 42 of the plate member 40. Since the filling region F for injecting the sealing agent 60 is formed, the sealing agent 60 can be filled without excess or deficiency.

(Modification example)
The description of the embodiment is an example of possible embodiments of the fixture and the mounting method of the fixture according to the present invention, and is not intended to limit the embodiment. In addition to the embodiment, the mounting tool and the mounting method of the mounting tool according to the present invention may take, for example, a modification of the embodiment shown below and a combination of at least two modifications that do not contradict each other.

The nut 32 of the mounting member 30 may be covered with another sheet by the same configuration as the seat 70. According to this example, the possibility of water entering from the nut 32 can be suppressed, and the watertightness effect is improved.

At least one of the second main surface 41B of the plate main body 41 constituting the filling region F, the inner surface 111A of the first opening 111, the first main surface 120A of the base material 120, and the bolt 31 existing in the filling region F. First, a primer for acclimatizing the sealing agent 60 may be applied. By applying the primer, the sealing action of the sealing agent 60 is improved, so that the watertight action is improved.
