Description

  The present invention is a fixture for fixing a building material, a metal fitting, or the like to an outer wall of a building or a roof member, and more specifically, a fixing that can be suitably used when fixing a mounting bracket for a solar cell module to a roof. It relates to ingredients. Moreover, this invention relates to the attachment method and roof structure for attaching a solar cell module to a roof.

  Various exterior members such as rain gutters, fences to prevent windows from falling, ladders, door pockets, door hinges, and air conditioner outdoor units are attached to the outer walls of general buildings. Various exterior members such as wings and mounting brackets for solar cell modules are also attached to the tiles and the like. These exterior members are integrally fixed to the outer wall and the roof member by a method such as drilling holes in the outer wall and the roof member and screwing them, or driving nails.

  However, according to the method of making a hole in the outer wall or the roof member in this way, water may leak from the hole provided in the outer wall or the roof member. That is, when a hole is made in the outer wall or the roof member with a screw or a nail, the hole may be made even in the waterproof sheet located inside the outer wall or the roof member. Then, there is a risk that water will enter the inside from the hole formed in the outer wall or roof member due to heavy rain, typhoon or the like, and may be submerged to the ground portion located inside the waterproof sheet.

  As a technique for preventing such intrusion of water, for example, there is a technique disclosed in Patent Document 1. Patent Document 1 discloses a technique for fixing a wing to a roof by a nail with packing in which a packing is attached in the vicinity of the head of the nail. That is, in the invention disclosed in Patent Document 1, the opening portion of the nail hole is closed by the packing attached near the head of the nail, thereby preventing water from entering the roof base side from the nail hole.

Japanese Patent Publication No.59-38383

  By the way, when the solar cell module is mounted on the roof, generally, a bracket for mounting the solar cell module (hereinafter also simply referred to as a mounting bracket) is mounted on a tile mounted on the roof base. And the solar cell module is attached on the roof by fixing the solar cell module to the mounting bracket. That is, on the roof base, two members, a tile and a mounting bracket, are attached in a state of overlapping in order.

  Moreover, such an attachment is generally attached by driving a nail or the like in a state of being piled on the roof tile. At this time, since it is necessary to drive the tip portion of the nail or the like into the roof base, the nail or the like is in a state of penetrating the mounting bracket and the roof tile. In other words, when the mounting bracket for mounting the solar cell module is mounted on the roof with a nail, the tip of the nail is driven into the roof base in a state of passing through the mounting bracket and the roof tile.

  Here, when the fitting for mounting the solar cell module is attached with a packing-provided nail disclosed in Patent Document 1, water may enter from between the attachment fitting and the roof tile. More specifically, when attaching a mounting bracket with a packing-attached nail (hereinafter also simply referred to as a nail), the nail is a communication hole formed by overlapping a nail hole formed in the mounting metal and a nail hole formed in the roof tile. Will be inserted. At this time, since the opening part located outside the nail hole formed in the mounting bracket can be closed by the packing attached to the nail, water does not enter from this opening part. However, the opening portion of the nail hole formed in the roof tile, that is, the roof opening portion of the roof tile that is in contact with the mounting bracket does not have a member that blocks water that has entered between the mounting bracket and the roof tile. Therefore, if water enters between the mounting bracket and the roof tile, the water may enter the roof base side from the opening portion of the nail hole formed in the roof tile.

  That is, in the nail with packing disclosed in Patent Document 1, when two or more members are stacked on the base, only the opening portion of the through hole formed in the uppermost member is liquid-tight. There was a problem that it could not be sealed.

  Then, this invention makes it a subject to provide the fixing tool which can be attached with higher water stop when attaching an exterior member to a building in view of the problem of an above-described prior art. It is another object of the present invention to provide a solar cell module mounting method and a roof structure that do not cause corrosion or rain leakage of members due to water immersion on the roof base side.

  The invention according to claim 1 for solving the above-mentioned problem is a fixture for attaching an exterior member to an outer wall or a roof member of a building, and is embedded at least partially in the outer wall or roof member of the building And the embedded piece is formed in advance, the rod-shaped body is formed of a rod-shaped body main body and a rod-shaped body side sealing portion, and the rod-shaped body main body penetrating the exterior member is By being inserted into an embedded piece, the exterior member is fixed in a state of being positioned between the rod-shaped body side sealing portion and the embedded piece.

Here, the rod-shaped body includes screws, nails, bolts and the like. In addition, the embedded piece is a solid material having a certain shape and volume, which is preliminarily molded in a natural state (a state where no external force is applied), and having shape retention.
The fixture of this invention has the embedded piece by which at least one part is embedded in the outer wall or roof member of a building, and the rod-shaped body formed from a rod-shaped body side sealing part and a rod-shaped body main body. And in the state which the rod-shaped body main body penetrated the exterior member, the exterior member is fixed to the outer wall or roof member of a building by inserting the one part into the embedded piece embedded in the outer wall or the roof member. Thus, the exterior member is attached in a state of being positioned between the rod-shaped body side sealing portion and the embedded piece.
Thereby, the opening part located in the outer side among the opening parts of the through-hole formed in the exterior member is block | closed by the rod-shaped body side sealing part. Therefore, water does not enter the ground side of the wall or roof from the outside of the exterior member through the through hole of the exterior member. Furthermore, the embedded piece is embedded in the outer wall or the roof member (tile or the like), and the rod-shaped body is inserted through the embedded piece. That is, the embedded piece is positioned around the outer wall of the rod-shaped body or the portion inserted through the roof member, in other words, between the inner peripheral wall of the through hole formed in the outer wall or the roof member and the rod-shaped body. There is an embedded piece. As a result, even if water intrudes between the exterior member and the surface of the outer wall or roof member, water can be prevented from entering the base side of the wall or roof by the embedded piece, so that the water is in the base of the wall or roof. Never reach. For these reasons, according to the fixture of the present invention, it is possible to reliably prevent water from entering the wall or the base of the roof, and it is possible to attach an exterior member having a high water-stopping property.

Furthermore, the fixing device of the present invention is a conventional method (fixing device) in which a coking material having high viscosity is injected into a prepared hole formed in the wall or roof member in order to embed a solid embedded piece in the wall or roof member. In comparison, the influence of aging of the peripheral members can be reduced, and the installation work can be simplified.
Concretely explaining this, when the caulking material is injected into the lower hole of the roof member or the like as in the conventional method, and the exterior member is fixed by inserting a screw or the like into the lower hole filled with the caulking material, The caulking material is dried and hardened in a state of being in close contact with the inner peripheral surface of the prepared hole and the screw after construction. Thus, the caulking material is integrally bonded to the inner peripheral surface of the prepared hole, the screw, or the like. Here, when a long time has passed since the completion of construction, the screw or the like may rust and expand, or the roof member (tile) may expand or contract due to exposure to heat such as sunlight or wind and rain. Then, because the caulking material is integrally bonded to the screw and the roof member, the caulking material is pulled outward in the radial direction of the pilot hole as the screw and the roof member expand and contract, or the radial direction of the pilot hole It will be pushed inward. When the hardened caulking material is pulled or pressed, damage such as cracks in the hardened caulking material occurs.
On the other hand, since the fixture of the present invention is configured to embed a solid embedded piece in the lower hole, the inner peripheral surface of the lower hole formed in the roof member and the embedded piece are bonded together. Absent. Further, since the embedded piece is not dried and hardened like a caulking material and is a fixed object, the screw and the embedded piece are also not bonded together. That is, even if the inner peripheral surface of the lower hole, the screw or the like and the embedded piece are in close contact with each other, they are in contact with each other in a pressed state, and are not bonded together and cannot be separated. Therefore, as described above, even if expansion or contraction of a screw or the like or a roof member occurs, the outer peripheral surface of the embedded side is not pulled, and the embedded piece is deformed along with the deformation of the screw or the roof member. Unreasonable power is not added. For this reason, generation | occurrence | production of the damage of an embedded piece can be suppressed. As described above, the fixture according to the present invention is configured not to be affected by the secular change of the peripheral members.
In addition, according to the fixture of the present invention, since it is only necessary to insert the embedded piece into the lower hole without performing the operation of injecting the caulking material into the lower hole using a caulking gun or the like, the outer wall of the building or the roof The mounting work of the exterior member to the can be simplified.

  The invention according to claim 2 is the fixture according to claim 1, wherein the embedded piece is a cylindrical body.

  According to such a configuration, since the cylindrical embedded piece has a through-hole formed in advance, it is easy to insert the rod-shaped body into the embedded piece.

  The invention according to claim 3 is characterized in that the rod-shaped body side sealing portion is elastically compressible, contacts the exterior member from the outside at the time of attachment, and has water-stopping property in the compressed state. Or it is a fixing tool of 2.

  According to such a configuration, it is possible to reliably prevent water from entering from the through hole formed in the exterior member. More specifically, when a rod-shaped body main body (for example, a screw or a nail) penetrating the exterior member is inserted into an outer wall or an embedded piece embedded in the roof member, the rod-shaped body main body moves toward the outer wall or the roof member side. Along with this, the rod-shaped body side sealing portion attached to the rod-shaped body main body also moves to the outer wall or the roof member side. And the rod-shaped body side sealing part comes into contact with the exterior member from the outside, and is further pressed and compressed toward the outer wall or roof member side. Here, since the rod-shaped body side sealing portion of the present invention has water-stopping property in a compressed state, water does not enter between the rod-shaped body side sealing portion and the exterior member. Therefore, water does not reach the through-hole of the exterior member located inside the edge portion of the rod-shaped body side sealing portion, and it is possible to more reliably prevent rain leakage and water intrusion to the roof base side.

  According to a fourth aspect of the present invention, in any one of the first to third aspects, the embedded piece is formed of an elastic material, and the diameter of the embedded piece is increased by inserting the rod-shaped body. It is a fixture of description.

According to such a configuration, when the rod-shaped body is not inserted into the embedded piece, the embedded piece has a relatively small diameter, and thus is easily embedded in the outer wall or the roof member. When the rod-shaped body is inserted into the embedded piece, the diameter of the embedded piece becomes relatively large, so that it is embedded in the inner peripheral surface of the through hole formed in the outer wall or the roof member. The outer peripheral surface of the piece is strongly pressed. Thus, the space between the inner peripheral wall of the through hole formed in the outer wall or the roof member and the outer peripheral wall of the embedded piece can be reliably sealed.
In addition, when the embedded piece is formed of an elastic member in this way, as described above, the screw or the like rusts and expands, or the roof member (tile) expands or contracts by being exposed to heat such as sunlight or wind and rain. Even if it is done, the shape of the embedded piece changes following the expansion and contraction of these peripheral members. For example, when the diameter of the lower hole of the roof member is reduced, the diameter of the embedded piece is also pressed by the inner peripheral surface of the lower hole and becomes smaller. Moreover, when the diameter of the lower hole of the roof member becomes large, the inner peripheral surface of the lower hole that has pressed the embedded piece moves to the outer side in the radial direction of the lower hole. The surface extends outward in the radial direction of the lower hole until it comes into close contact with the inner peripheral surface of the lower hole. That is, since the shape of the embedded piece is deformed according to the expansion or contraction of the peripheral member, an excessive force is not applied to the embedded piece even if the shape of the peripheral member such as a screw or a roof member is deformed. For this reason, it is hard to receive the influence by a secular change of a peripheral member, and generation | occurrence | production of the damage of an embedded piece can be suppressed reliably.

  A fifth aspect of the present invention is the fixture according to any one of the first to fourth aspects, wherein one or a plurality of step portions are formed on the outer surface of the embedded piece.

  According to this configuration, the step portion is formed on the outer surface of the embedded piece. That is, a portion projecting outward on the outer surface of the embedded piece and a portion recessed inward are formed. Therefore, when the embedded piece is embedded in the through hole formed in the outer wall or the roof member, the inner peripheral wall of the through hole formed in the outer wall or the roof member and the embedded piece are compared with the case where the step portion is not formed. The contact area with the outer peripheral surface is reduced. As a result, the force per area acting between the inner peripheral wall of the through hole formed in the outer wall or the roof member and the outer peripheral surface of the embedded piece increases, and the inner peripheral wall of the through hole and the outer peripheral surface of the embedded piece It becomes easy to apply force between. That is, the frictional force between the inner peripheral wall of the through hole and the outer peripheral surface of the embedded piece increases. Therefore, when the embedded piece is inserted and embedded in the through hole, the embedded piece is unlikely to come out to the outside, and is difficult to fall off to the wall base or roof base side.

  The invention according to claim 6 is characterized in that the rod-shaped body side sealing portion includes a covering portion, and the covering portion can cover at least part or all of the vicinity of the outer end portion of the rod-shaped body main body. A fixing tool according to any one of claims 1 to 5.

According to such a configuration, when the fixture is used in a cold region, it is possible to prevent corrosion of the member near the roof base due to condensed water.
More specifically, in cold regions, it is common to warm the room with a heating device or the like as a countermeasure against cold. And in a general building, since moisture generation sources, such as a breath of a resident, water supply, and a gas appliance, exist indoors, indoor humidity is high compared with the outdoors. That is, in cold regions, the temperature difference between the outdoors and indoors is large, and indoor humidity is often higher than outdoors.
Here, when attaching an exterior member on an outer wall or a roof member, the front-end | tip of a fixing tool (for example, screw or a nail | claw) is driven into a wall base side or a roof base side. At this time, there is a case where the tip of the fixing tool is embedded in a timber or the like that is assembled, and a case where the tip of the fixing tool is exposed to a space formed on the back side of the wall or the attic. That is, the fixing tool is inserted in the space formed on the wall base side or the roof base side by passing between the wooden pieces with the tip of the fixing tool attached between the wooden pieces or passing through the wooden pieces. May be exposed.
In this case, the fixed tool (for example, screw or nail) that has been driven is in a state in which one end (head side) is exposed to the outside, and the other end (tip side) is on the wall base side or roof base side. It will be in the state located in the space formed.
And the temperature of the whole fixture may fall because the edge part (head) exposed in this state is cooled by the cold outdoor air outdoors. In this case, as a matter of course, the temperature of the portion (tip portion) exposed in the space on the wall base side or roof base side of the fixture also decreases. Then, on the indoor side where the temperature and humidity are high, the temperature in the vicinity of the fixture is lowered, and therefore, condensation may occur at a portion where the temperature is lowered (the fixture surface). As described above, when dew condensation occurs inside the wall or the roof, members inside the wall or the roof may be corroded by the dew condensation water.
Therefore, in the present invention, the outer portion of the fixture exposed to the outside is covered with the covering portion. This prevents the fixture from being overcooled because it is not directly exposed to the cold outdoor air. Therefore, it is possible to prevent the occurrence of condensation based on the temperature drop of the fixture as described above.

  The invention according to claim 7 is the fixture according to claim 6, wherein the covering portion is formed of a heat insulating member.

  According to such a configuration, it is possible to reliably prevent the fixing device from being cooled by the outside air by blocking the outside air with the covering portion.

  The invention according to claim 8 is the fixture according to any one of claims 1 to 7, wherein the exterior member is a fixture for a solar cell module.

  The fixture of this invention can be used suitably for the attachment to the roof of the fixture (attachment metal fitting) of a solar cell module.

  The invention according to claim 9 is an attachment of a solar cell module for attaching a solar cell module attachment to a building having a basic roof structure on which a plurality of roof members are mounted using the fixture according to claim 8. A method of attaching a tool, the step of forming a through hole in the roof member, the step of inserting the embedded piece into the through hole formed in the roof member, and the through-hole of the solar cell module through the rod body A method for attaching a solar cell module attachment, comprising the step of inserting the rod-shaped body into the embedded piece.

  In the solar cell module fixture mounting method of the present invention, the embedded piece is embedded in the through hole formed in the roof member, so that water enters the roof base side from the through hole formed in the roof member. There is no. Moreover, since the rod-shaped body side sealing portion of the rod-shaped body closes the through-hole formed in the solar cell module attachment, water does not enter the roof base side from the through-hole of the solar cell module attachment. As a result, it is possible to reliably prevent water from entering the roof base, and thus problems such as rain leakage and roof base corrosion can be reliably prevented.

  The invention according to claim 10 is characterized in that the rod-shaped body has a head portion and a shaft portion, and the diameter of the through hole formed in the roof member is larger than the diameter of the shaft portion. 9 is a method for attaching a solar cell module attachment according to item 9.

In the solar cell module mounting method according to the present invention, the embedded piece is inserted into the prepared hole formed in the roof member, and the rod-shaped body is inserted into the embedded piece. This reduces design restrictions when forming a pilot hole in the roof member, compared to the conventional configuration in which screws, nails, etc. (rod-like body) are directly inserted into the pilot hole formed in the roof member. it can.
This will be explained in detail. When the lower hole of the roof member is inserted with a screw, nail, etc. as in the conventional method, the diameter of the pre-formed preform hole is determined from the diameter of the shaft portion of the screw, nail, etc. There is a construction limit that must be reduced. That is, if the diameter of the lower hole is larger than the diameter of the shaft portion of the screw, nail, etc., when the screw, nail is inserted into the lower hole, the inner surface of the lower hole and the outer surface of the screw, nail, etc. A gap is formed. If such a gap is formed, not only the posture of the inserted screws, nails, etc. is not stable, but also a problem that water such as rainwater enters from the gap to the roof base side occurs. Therefore, the diameter of the prepared hole formed in the roof member is usually smaller than that of the shaft portion such as a screw or a nail. Then, by inserting screws, nails, and the like into the lower holes, the lower holes are pushed and expanded by the screws, nails, etc., and the outer peripheral surface of the screws, nails, etc. and the inner peripheral surface of the lower hole are brought into close contact with each other. That is, by closely attaching screws, nails, etc. to the lower holes, the gaps between the screws, nails, etc. and the lower holes are closed, and the intrusion of water from the gaps to the roof base side is prevented. Therefore, in the conventional method, when an operator forms a pilot hole in a roof member, it is necessary to form a hole smaller than a shaft portion such as a screw or a nail. In other words, in the conventional method, formation of a pilot hole with a small diameter is desired from the viewpoint of preventing water from entering the roof base side.
On the other hand, in the method of attaching the solar cell module fixture using the fixture of the present invention, an embedded piece is inserted into a prepared hole formed in the roof member, and a shaft portion such as a screw or a nail is inserted into the embedded piece. Yes. As a result, the embedded piece is located between the outer peripheral surface of the shaft portion such as the screw or the nail and the inner peripheral surface of the lower hole. For this reason, when the pilot hole formed in the roof member is larger than the shaft portion such as a screw or a nail, further speaking, even if the pilot hole formed in the roof member is sufficiently large, it corresponds to the diameter of the formed pilot hole. By inserting a large embedded piece, the vicinity of the inner peripheral surface of the prepared hole can be sealed in a state where water does not leak. Therefore, it is not necessary to make the pilot hole formed in the roof member small, and a pilot hole with a large diameter may be used. In other words, since the diameter of the pilot hole formed in the roof member does not have to be matched to the diameter of the shaft portion such as a screw or a nail, the design restriction of the pilot hole formed in the roof member can be reduced. .

  The invention according to claim 11 has a basic roof structure in which a plurality of roof members are arranged in a row and a plurality of steps on a roof base and are mounted with a planar spread, and the basic roof structure is provided on the basic roof structure. The fixture of a solar cell module is being fixed via the fixture of Claim 8, and a plurality of solar cell modules are attached to the foundation roof structure via the fixture of the solar cell module. It is a characteristic roof structure.

  In the roof structure of the solar cell module of the present invention, the through hole formed in the fixture of the solar cell module is closed by the rod-shaped body side sealing portion of the rod-shaped body, and the embedded piece tightly plugs the hole formed in the roof member. Intrusion of water into the roof base can be reliably prevented, and problems such as rain leakage and corrosion of members can be reliably prevented.

The fixing device of the present invention has an effect that water can be reliably prevented from entering a base portion located inside the outer wall or the roof member when the exterior member is attached to the building. As a result, there is an effect that problems such as corrosion of members near the base and rain leakage do not occur.
Furthermore, since the fixture of the present invention is configured to embed a solid embedded piece in an outer wall or a roof member, the outer surface of the embedded piece is integrally bonded to the outer wall or the roof member like a conventional caulking material. There is no. Therefore, even if the outer wall or the roof member expands and contracts with the passage of a long period of time, an excessive force is not applied to the embedded piece. Accordingly, it is difficult to be affected by the secular change of the peripheral members, and the occurrence of damage to the embedded piece can be suppressed.
In addition, the fixing device according to the present invention only needs to insert the embedded piece into the lower hole without performing the operation of injecting the caulking material into the lower hole using a caulking gun or the like. The work of attaching the exterior member to the top can be simplified.
In addition, the solar cell module mounting method of the present invention is such that even if the solar cell module mounting device is fixed on the roof by screws, nails, etc., the members corrode due to rain leakage or water intrusion into the roof base side. There is an effect that such a problem does not occur.
The roof structure according to the present invention has an effect that the building is long-lasting because the base is not easily damaged and rain leakage does not occur.

  A lower plate member 27 is disposed between the bottom plate portion 16 and the placement portion 18 of the rail member 10, and an upper plate member 26 is disposed above the placement portion 18 of the rail member 10. The upper plate member 26 and the lower plate member 27 are arranged so that their central portions overlap each other, and the through holes of the upper plate member 26 and the through holes of the lower plate member 27 have the same center axis. . Then, the pressing bolt 25 communicates the through hole of the lower plate member 27 and the through hole of the upper plate member 26 with the head (not shown) disposed on the lower side, and the female screw hole of the pressing nut 28. The upper plate member 26 is screwed on the upper side. In other words, the lower plate member 27 is located above the head (not shown) of the pressing bolt 25, the upper plate member 26 is located above the lower plate member 27, and the upper side of the upper plate member 26. A pressing nut 28 is located on the top.

As a result, the mounting bracket 4 of the present embodiment has a rail member by sandwiching the frame of the solar cell module 7 between the top surface of the mounting portion 18 of the rail member 10 and the bottom surface of the upper plate member 26 of the fixing member 11. The solar cell module 7 can be fixed on the top 10.
More specifically, in the fixing member 11, the interval between the upper plate member 26 and the lower plate member 27 is narrowed by tightening the pressing nut 28. That is, when the pressing nut 28 is tightened, the pressing bolt 25 moves relatively upward with respect to the pressing nut 28. As a result, the head (not shown) of the pressing bolt 25 located below the lower plate member 27 also moves upward. Then, the lower plate member 27 pressed by the head of the pressing bolt 25 moves upward. The bottom surface of the upper plate member 26 comes into contact with the mounting portion 18 of the rail member 10 from the upper side, and the upper surface of the lower plate member 27 comes into contact with the mounting portion 18 of the rail member 10 from the lower side.
Therefore, the frame of the solar cell module 7 is placed on the top surface of the placement portion 18 with the gap between the upper plate member 26 and the lower plate member 27 being widened, and the gap between the upper plate member 26 and the lower plate member 27 is reduced. Thus, the frame of the solar cell module 7 can be sandwiched and fixed between the upper plate member 26 and the mounting portion 18. At this time, the frame of the solar cell module 7 can be firmly fixed by inserting a part of the frame of the solar cell module 7 into the engaging groove 29 provided in the upper plate member 26 of the fixing member 11.

  Next, the attachment method of the solar cell module 7 by the attachment metal fitting 4 of this embodiment is demonstrated. In addition, as shown in FIG. 2, although the case where the solar cell module 7 is attached to the well-known basic roof structure 3 in which the slate tile 2 (roof member) is laid on the roof base 45 (see FIG. 8), Of course, the roof structure to which the mounting bracket 4 of this embodiment is attached is not limited to this.

  First, prior to installation of the solar cell module 7, the mounting bracket 4 is attached on the basic roof structure 3 which is a completed roof structure. At this time, the attachment fitting 4 is attached to the slate roof tile 2 via the fixture 33. The fixture 33 which is a characteristic configuration of the present embodiment will be described in detail with reference to FIGS.

  As shown in FIG. 5, the fixture 33 includes a rod-shaped body 34 and an embedded piece 35 (tubular body).

  The rod-shaped body 34 has a rod-shaped body main body 36 and a rod-shaped body side sealing portion 37.

The rod-shaped body 36 is a fastening element such as a wood screw, a nail, or a bolt, and in this embodiment, a screw having a sharp tip is adopted. More specifically, the rod-shaped body main body 36 is formed of a head portion 36a and a shaft portion 36b. The head portion 36a is a frustoconical portion formed at one end portion in the longitudinal direction of the shaft portion 36b, and the diameter increases from the center side of the shaft portion 36b toward the end portion side. At this time, the part with the smallest diameter of the head part 36a is substantially the same diameter as the shaft part 36b, and the other most part of the head part 36a is larger in diameter than the shaft part 36b. In addition, the end portion of the shaft portion 36b facing the head portion 36a is tapered from the center side of the shaft portion 36b toward the end portion, and the tip portion is sharp. And the thread is formed in the outer peripheral surface of the axial part 36b.
Note that the above-described fastening elements are superordinate concepts such as screws, nails, bolts, and the like.

The rod-shaped body side sealing portion 37 is a cylindrical member having a low height, and a through hole 37a having a circular opening shape penetrating from the top surface to the bottom surface is formed at the central portion thereof. The rod-shaped body side sealing portion 37 is formed of an elastic material that has a water-stop property when compressed. Specifically, butyl rubber, acrylic rubber, fluororubber (Viton), multi-flow rubber (thiocol), and the like are used. Styrene butadiene rubber, nitrile rubber, ethylene propylene rubber, chlorosulfonated polyethylene rubber (hypalon), ethylene vinyl acetate rubber, epichlorohydrin rubber, etc. are preferable, natural rubber, synthetic natural rubber (isoprene rubber), butadiene rubber, chloroprene rubber, Urethane rubber and silicone rubber are more desirable. That is, a material having high resilience (a force that pushes back a portion to which an external force is applied when an external force is applied) is desirable.
In this embodiment, it is assumed that the rod-shaped body side sealing portion 37 is formed of hard butyl rubber. Here, “hard” is a solid material having a shape-retaining property having a certain shape and volume in a natural state (a state in which no external force is applied). And the rod-shaped body side sealing part 37 of this embodiment can be elastically deformed (reversible deformation), deforms when an external force is applied, and returns to its original shape when the external force is removed.

  The rod-shaped body 34 is in a state where the shaft portion 36 b of the rod-shaped body main body 36 is inserted into the through hole 37 a of the rod-shaped body side sealing portion 37. At this time, the diameter of the through hole 37a in a state where the shaft portion 36b is not inserted is smaller than the diameter of the shaft portion 36b of the rod-shaped body main body 36. Then, by inserting the shaft portion 36b into the through hole 37a, the inner peripheral surface of the through hole 37a is pressed outward by the outer peripheral surface of the shaft portion 36b, the diameter of the through hole 37a is increased, and the shaft portion 36b is inserted. It becomes possible. As a result, when the shaft portion 36b is inserted into the through hole 37a, the outer peripheral surface of the shaft portion 36b and the inner peripheral surface of the through hole 37a are in a liquid-tight contact state. When the rod-shaped body side sealing portion 37 is attached to the rod-shaped body main body 36, the rod-shaped body side sealing portion 37 is disposed at a position close to the head 36 a of the rod-shaped body main body 36.

  The embedded piece 35 is a substantially cylindrical member formed of a highly elastic member such as EPDM (ethylene propylene rubber) having high durability and water-stopping properties. As shown in FIG. A through hole 32 penetrating from the top surface to the bottom surface is formed in the central portion of. Although not particularly limited, when a screw thread is formed on the shaft portion 36b of the rod-shaped body main body 36, the diameter of the through hole 32 is the diameter of the screw groove portion of the shaft portion 36b ( It is desirable that the diameter of the portion excluding the thread of the shaft portion 36b is substantially equal to the size of the portion having the smallest diameter.

Further, as shown in FIGS. 5 and 6, the embedded piece 35 has a diameter that gradually decreases from one end to the other end.
Specifically, as shown in FIG. 6, a stepped portion 38 is formed on the side surface of the embedded piece 35. The projecting pieces 39, 39, 39, 39 formed over the entire circumference of the embedded piece 35 are formed so that the stepped portion 38 protrudes outward from the center side of the embedded piece 35. It is formed by providing continuously in the axial direction. As a result, the side surface of the embedded piece 35 is in a state in which the portions protruding outward and the concave portions 40 recessed inward are alternately continued. The projecting piece 39 has a gentle inclined surface that gradually becomes narrower in diameter from the most projecting portion located at the upper end to the concave portion 40 continuous with the projecting piece 39 on the lower side. That is, the outer shape of each protruding piece 39 is a substantially hemispherical shape that protrudes downward.

  Here, the projecting pieces 39, 39, 39, 39 provided continuously in the axial direction of the embedded piece 35 have different sizes, and the diameter of the projecting portion 39 that is the most projecting in the projecting piece 39 located below is smaller. It is getting smaller. That is, the projecting pieces 39, 39, 39, 39 having different maximum diameters continue in the order of the maximum diameter from the embedded piece 35 toward one end (upper end) to the other end (lower end). It is provided as follows. Thereby, the size of the side surface of the embedded piece 35 gradually decreases from the one side end (upper end) toward the other end (lower end). That is, the two straight lines L1 and L2 formed by connecting the most projecting portions of the projecting pieces 39, 39, 39, and 39 at both end portions in the width direction of the embedded piece 35 are formed from one end portion (upper end). It approaches gradually toward the other end (lower end).

  A flange portion 41 having a diameter larger than that of the side surface portion is formed at the upper end portion of the embedded piece 35.

  Next, a method for mounting the mounting bracket 4 on the slate roof tile 2 by the fixture 33 of the present embodiment will be described in detail with reference to FIGS.

First, as shown in FIG. 7A and FIG. 8A, a lower hole 43 (through hole) is formed in advance at a position where the mounting bracket 4 of the slate roof tile 2 is to be installed. At this time, it is assumed that the waterproof sheet 44 and the roof base 45 are not perforated. Next, a large embedded piece 35 corresponding to the diameter of the lower hole 43 formed in the slate tile 2 is inserted. The diameter of the lower hole 43 formed in the roof tile 2 is 0.5 mm from the maximum diameter of the step portion 38 formed on the side surface of the embedded piece 35 of the fixture 33 (maximum diameter in a state where the rod-shaped body 34 is not inserted). It is desirable that the distance is reduced by 1.5 mm, and more desirably by 0.5 mm to 1.0 mm. That is, the maximum diameter of the embedded piece 35 of the fixture 33 is preferably larger by 0.5 mm to 1.5 mm than the diameter of the lower hole 43, and more preferably larger by 0.5 mm to 1.0 mm.
In addition, when the solar cell module 7 is installed on the basic roof structure 3 as shown in FIG. 2, the both ends of the roof of the solar cell module 7 in the row direction are positioned as shown in FIG. Is a place.

  Further, as shown in FIGS. 7B and 8B, the embedded piece 35 of the fixture 33 is inserted into the lower hole 43 formed in the slate roof tile 2. At this time, the flange portion 41 located at the upper end portion of the embedded piece 35 is located above the upper end opening of the lower hole 43. Then, the lower surface of the flange portion 41 comes into contact with the upper surface of the slate roof tile 2. At this time, as described above, the diameter of the lower hole 43 formed in the slate roof tile 2 is slightly smaller than the maximum diameter of the stepped portion 38 formed on the side surface of the embedding piece 35 of the fixture 33 (from 0.5 mm to 0.5 mm). It is desirable to be smaller by 1.5 mm, more desirably smaller by 0.5 mm to 1.0 mm). Therefore, the embedded piece 35 inserted into the lower hole 43 is difficult to come off in the vertical direction (attachment direction). Although not particularly limited, the diameter of the lower hole 43 formed in the slate roof tile 2 is the recessed portion 40 having the largest diameter among the recessed portions 40 of the embedded piece 35 (the recessed portion positioned on the uppermost side in FIG. 6). 40) may be substantially the same as the diameter.

  Then, as shown in FIG. 7C and FIG. 8C, the mounting bracket 4 is placed above the lower hole 43 and the embedded piece 35. At this time, as shown in FIG. 9A, since the mounting bracket 4 is pressed downward by its own weight, the portion 14a in contact with the flange portion 41 of the embedded piece 35 of the roof protection member 14 is upward. It will be in a depressed state. As a result, the lower surface of the roof protection member 14 and the upper surface of the embedded piece 35 and the slate tile 2 are in close contact with each other without a gap. Then, the mounting hole 20 of the bottom plate portion 16 of the rail member 10, the mounting hole 21 of the roof protection member 14, and the through hole 32 of the embedded piece 35 overlap to form an integral hole.

  Here, as shown in FIGS. 7D and 8D, the rod-shaped body 34 of the fixture 33 is inserted into a hole formed by overlapping the two mounting holes 20 and 21 and the through hole 32. The rod-shaped body 34 penetrates the waterproof sheet 44 under the slate roof tile 2 by further screwing (pushing) the inserted rod-shaped body 34. Further, when the rod-shaped body 34 penetrating the waterproof sheet 44 is further pressed (screwed or pushed) toward the roof base 45, a locking hole 47 is formed in the roof base 45. At this time, the attachment bracket 4 is fixed to the slate tile 2 and the roof base 45 by engaging the portion on the distal end side of the rod-shaped body 34 with the locking hole 47. In other words, the rail member 10 and the slate tile 2 are integrally attached to the roof base 45 via the rod-shaped body 34.

  As described above, in this embodiment, the diameter of the lower hole 43 formed in the slate roof tile 2 is slightly smaller by 0.5 mm to 1.5 mm than the maximum diameter of the stepped portion 38 of the embedded piece 35 in the natural state. Preferably smaller by 0.5 mm to 1.0 mm). Here, the diameter of the shaft portion 36b of the rod-shaped body main body 36 is slightly larger than the diameter of the through hole 32 formed in the embedded piece 35 (see FIG. 5). Therefore, the diameter of the lower hole 43 formed in the slate roof tile 2 is sufficiently larger than the diameter of the shaft portion 36 b of the rod-shaped body main body 36. Thus, in the present embodiment, the diameter of the lower hole 43 formed in the slate roof tile 2 can be made larger than in the conventional method in which a screw thread is directly inserted into the lower hole formed in the slate roof tile. Therefore, a larger hole can be formed than before when the lower hole 43 is formed, and there is also an advantage that the work of forming the lower hole 43 (FIG. 7A) is facilitated.

  In this embodiment, when the lower hole 43 is formed in the slate roof tile 2 in advance, a larger hole than before can be formed. That is, it is completely different from the conventional method in which the diameter of the lower hole 43 is made as small as possible so as to make the cross-sectional area into which water can enter as small as possible. It has a configuration. In this embodiment, the rod-shaped body 34 is not formed by forming a hole in the waterproof sheet 44 and the roof base 45 by a method such as forming the lower hole 43 in a state where the slate tile 2 is not in contact with the waterproof sheet 44 or the roof base 45. When the is engaged with the roof base 45, the rod-shaped body 34 forms holes (holes) in the waterproof sheet 44 and the roof base 45. Thus, the diameter of the hole formed in the waterproof sheet 44 can be made substantially the same as the diameter of the shaft portion 36b of the rod-shaped body 34. That is, the gap between the inner periphery of the hole formed in the waterproof sheet 44 and the shaft portion 36b of the rod-like body 34 can be eliminated or substantially eliminated. For this reason, the function of the waterproof sheet 44 can be prevented from being impaired or hardly impaired.

  Further, when the mounting bracket 4 is fixed to the slate tile 2 and the roof base 45, when the mounting bracket 4 is mounted on the slate roof tile 2, the roof protection member 14 is compressed by being pressed by the main body member 13. Here, since the roof protective material 14 of this embodiment has high water-stopping property even in a compressed state, it prevents or suppresses the intrusion of water such as rain water or snow-melted water between the slate tile 2 and the roof protective material 14. it can. In other words, water can be prevented or suppressed from entering from the four circumferences of the mounting bracket 4 to the inside. Therefore, water such as rainwater reaches the position of the attachment hole 20 of the main body member 13, the attachment hole 21 of the roof protection material 14, and the lower hole 43 of the slate tile 2 from between the lower surface of the roof protection material 14 and the upper surface of the slate tile 2. No or very little.

  At this time, as shown in FIG. 9B, the rod-shaped body side sealing portion 37 of the rod-shaped body 34 is pressed downward (on the roof base 45 side) by the head portion 36 a of the rod-shaped body main body 36. As a result, the rod-shaped body side sealing portion 37 contacts the upper surface of the bottom plate portion 16 of the mounting bracket 4 in a compressed state, and closes the opening of the mounting hole 20 of the bottom plate portion 16. At this time, since the rod-shaped body side sealing portion 37 has a high water-stopping property even in a compressed state, the intrusion of water such as rain water between the lower surface of the rod-shaped body side sealing portion 37 and the upper surface of the bottom plate portion 16 is prevented or suppressed. it can. In other words, the intrusion of water from the outer edge portion of the rod-shaped body side sealing portion 37 to the inside can be prevented or suppressed. Therefore, water such as rainwater does not reach the position of the mounting hole 20 of the bottom plate portion 16 from the space between the lower surface of the rod-shaped body side sealing portion 37 and the upper surface of the bottom plate portion 16 or only slightly.

  Further, at this time, as shown in FIGS. 9A and 9B, the shaft portion 36b of the rod-shaped body 34 is inserted into the through-hole 32 of the embedded piece 35, whereby the through-hole of the embedded piece 35 is obtained. 32 expands in diameter. At this time, the outer peripheral surface of the shaft portion 36 b is tightened from the inner peripheral surface of the through hole 32. As a result, the outer peripheral surface of the shaft portion 36b and the inner peripheral surface of the through-hole 32 are in close contact with each other and are sealed in a liquid-tight manner. At this time, the embedded piece 35 is pressed from the center side to the outside by the shaft portion 36b of the rod-shaped body 34. For this reason, the embedded piece 35 is deformed so as to expand outward, and the outer peripheral side surface (stepped portion 38) is pressed against the inner peripheral surface of the lower hole 43 of the slate roof tile 2. The gap 49 (see FIG. 9A) formed between the outer peripheral surface of the embedded piece 35 and the lower hole 43 of the slate roof tile 2 is filled with the embedded piece 35 deformed so as to expand outward. (See FIG. 9B). Thus, since the outer peripheral side surface (stepped portion 38) of the embedded piece 35 is strongly pressed against the inner peripheral surface of the lower hole 43 of the slate roof tile 2, the outer peripheral side surface (stepped portion 38) and the lower hole 43 of the embedded piece 35 are pressed. A state in which the inner peripheral surfaces are in close contact with each other without a gap is obtained, and sufficient liquid tightness can be secured. Further, since the gap 49 formed between the lower holes 43 of the slate roof tile 2 is eliminated or almost eliminated, the liquid tightness can be further improved.

  That is, by inserting the shaft portion 36 b of the rod-shaped body 34 into the through hole 32 of the embedded piece 35, the space between the outer peripheral surface of the shaft portion 36 b and the inner peripheral surface of the through hole 32, and the outer peripheral side surface ( The step portion 38) and the inner peripheral surface of the lower hole 43 of the slate roof tile 2 are in close contact with each other without any gap, and the space between them is liquid-tightly sealed.

  Above, description of the attachment method of the attachment metal fitting 4 on the slate roof tile 2 by the fixing tool 33 is complete | finished. With this method, as shown in FIG. 1, by attaching a predetermined number of mounting brackets 4 to predetermined locations on the foundation roof structure 3, the mounting work of the mounting brackets 4 on the foundation roof structure 3 can be performed. Complete.

  Then, as shown in FIG. 2, the frame portion of the solar cell module 7 is fixed by the mounting bracket 4. By repeating this process and fixing all the solar cell modules 7 to the mounting bracket 4 on the basic roof structure 3, the mounting operation of the solar cell module 7 on the roof by the mounting bracket 4 is completed.

  In the above-described embodiment, the case where the mounting bracket 4 provided with the roof protection material 14 is mounted on the slate tile 2 has been described. However, the mounting bracket of the solar cell module fixed by the fixing tool of the present invention is not limited to this. For example, the fixture of the present invention may be used for mounting a metal fitting that does not have a roof protection material and places the bottom plate portion directly on the slate tile 2. In the fixture of the present invention, the space between the outer peripheral surface of the shaft portion 36b of the rod-shaped body main body 36 and the inner peripheral surface of the through hole 32 formed in the embedded piece 35 is liquid-tightly sealed and embedded. The space between the outer peripheral side surface of the piece 35 and the inner peripheral surface of the lower hole 43 of the slate roof tile 2 is sealed in a liquid-tight manner. Therefore, even if water such as rain or snow-melted water reaches the vicinity of the upper opening of the lower hole 43 of the slate roof tile 2, the water does not enter the roof base 45 side.

  Further, the embedded piece and the lower hole 43 of the fixture of the present invention are not limited to the above-described embodiment. For example, the diameter of the lower hole 43 is made smaller or the maximum diameter of the embedded piece is made larger. The relative size of the diameter of the lower hole 43 with respect to the embedded piece may be made smaller by increasing the size. When the embedded piece is inserted into the lower hole 43, the upper portion of the stepped portion 38 formed in the embedded piece (the portion where the diameter of the embedded piece is large) is positioned above the upper surface of the slate roof tile 2. May be. That is, when the embedded piece is inserted into the lower hole 43, a part of the stepped portion 38 may protrude upward from the slate roof tile 2. In this case, the lower surface of the flange portion 41 formed on the embedded piece may not be in contact with the upper surface of the slate roof tile 2. That is, the lower surface of the flange portion 41 formed in the embedded piece does not necessarily need to be in contact with the upper surface of the slate roof tile 2 as long as the lower surface of the flange portion 41 and the upper surface of the slate roof tile 2 are close to each other. According to such a configuration, before the embedded piece is completely inserted into the lower hole 43, a part of the embedded piece can be hooked and temporarily fixed while being inserted into the lower hole 43.

  The fixing device of the present invention will be described below with respect to an embodiment different from the above-described first embodiment. However, the same reference numerals are given to the same structures as those of the above-described first embodiment, and description thereof will be omitted. .

  As shown in FIG. 10, the rod-shaped body 60 of the second embodiment of the present invention includes a rod-shaped body main body 36 and a rod-shaped body side sealing portion 61.

  And the rod-shaped body side sealing part 61 of this embodiment is provided with the sealing part main body 62, the coating | coated part 63, and the connection part 64. FIG.

The sealing portion main body 62 is a cylindrical member having a low height, and a through hole 62a having a circular opening shape penetrating from the top surface to the bottom surface is formed at the center thereof.
The sealing body 62 is made of an elastic material that has a water-stop property when compressed. Specifically, butyl rubber, acrylic rubber, fluororubber (Viton), multi-flow rubber (thiocol), etc. are used. Styrene butadiene rubber, nitrile rubber, ethylene propylene rubber, chlorosulfonated polyethylene rubber (hypalon), ethylene vinyl acetate rubber, epichlorohydrin rubber, etc. are preferable, natural rubber, synthetic natural rubber (isoprene rubber), butadiene rubber, chloroprene rubber, urethane Rubber, silicone rubber, etc. are more desirable. That is, a material having high resilience (a force that pushes back a portion to which an external force is applied when an external force is applied) is desirable.
In the present embodiment, it is assumed that the sealing portion main body 62 is formed of hard butyl rubber. Here, “hard” is a solid material having a shape-retaining property having a certain shape and volume in a natural state (a state in which no external force is applied). And the sealing part main body 62 of this embodiment can be elastically deformed (reversible deformation), deforms when an external force is applied, and returns to its original shape when the external force is removed.

The covering portion 63 is a member having a hemispherical outer shape, and a concave portion 65 is formed in an inner portion thereof. The concave portion 65 is a substantially cylindrical space with one end open, and is continuous with the outside through a circular opening 65 a formed in the flat portion 63 a of the covering portion 63. The diameter of the cross section of the recess 65 (the diameter of the opening 65a) is slightly smaller than the maximum diameter of the head portion 36a of the rod-shaped body main body 36.
The covering portion 63 is formed of hard butyl rubber, which is the same material as the sealing portion main body 62. That is, the covering portion 63 is made of a material having elasticity, low thermal conductivity, and heat insulation.

  The connecting portion 64 is a string-like body extending in a circular cross section, and is continuous with the sealing portion main body 62 at one end portion thereof and continuous with the covering portion 63 at the other end portion.

  As shown in FIG. 10, the rod-shaped body 60 of the present embodiment can cover the head portion 36 a of the rod-shaped body main body 36 with a covering portion 63. More specifically, the covering portion 63 is brought close to the head portion 36a of the rod-shaped body main body 36 from the flat portion 63a side, and the head portion 36a of the rod-shaped body main body 36 is pushed into the recess 65 of the covering portion 63. At this time, since the covering portion 63 is formed of a material having elasticity, the recessed portion 65 is expanded outward by pressing the head portion 36a. When the head 36 a is pushed in, the head 36 a is tightened by the inner peripheral surface of the recess 65. Thereby, the coating | coated part 63 can be fixed to the head 36a. At this time, the head 36a is surrounded by the covering portion 63. In this manner, by storing the head portion 36a of the rod-shaped body 36 in the recess 65, the internal space in which the head portion 36a is stored is blocked by the outside air by the covering portion 63 having heat insulating properties, and the head portion 36a is Since it is not exposed to outside air, it can prevent that the rod-shaped body main body 36 is cooled by outside air.

  Furthermore, the rod-shaped body 70 of the 3rd Embodiment of this invention is demonstrated.

  As shown in FIG. 11, the rod-like body 70 of the third embodiment of the present invention includes a rod-like body main body 36 and a rod-like body side sealing portion 71.

  And the rod-shaped body side sealing part 71 of this embodiment is provided with the sealing part main body 72, the coating | coated part 73, and the connection part 64. FIG.

The sealing portion main body 72 is a member in which a substantially mirror-like main body portion 74 in which flat hemispherical portions are stacked and a substantially disc-shaped flange portion 75 continuous with the lower end of the main body portion 74 are integrally formed. .
A stepped portion 76 is formed on the outer peripheral surface of the main body portion 74, and the projecting pieces 77, 77, 77 formed over the entire circumference of the main body portion 74 are formed in the axial direction of the main body portion 74. It is formed by providing continuously. And between each protrusion piece 77 is dented inside, and it is the recessed parts 78 and 78 whose diameter is smaller than the circumference | surroundings. That is, on the outer peripheral surface of the main body 74, the protruding pieces 77 and the recesses 78 are alternately continued in the axial direction. Further, a gently sloping surface gradually increases in diameter from a portion located at the upper end of the projecting piece 77 to a most projecting portion located at the lower end of the projecting piece 77. In other words, the outer shape of each projecting piece 77 is a substantially hemispherical shape that is convex upward and flat. Moreover, the diameter of each protrusion piece 77 is so small that the protrusion piece 77 located in an upper side. That is, the diameter of the projecting piece 77 located on the lowermost side is the largest, and the diameter of the projecting piece 77 located on the uppermost side is the smallest.

  Here, the diameter of the flange portion 75 is larger than the maximum diameter of the main body portion 74.

  Further, the main body 74 and the flange portion 75 are formed with through holes 79 and 80 having circular openings from the upper end to the lower end, respectively. And these two through-holes 79 and 80 are connected. At this time, the diameter of the through hole 79 formed in the main body portion 74 is larger than the diameter of the through hole 80 formed in the flange portion 75, and the two through holes 79 and 80 are continuous through a step. Yes. The diameter of the through hole 79 formed in the main body 74 is substantially the same as the maximum diameter of the head portion 36a of the rod body 36, and the diameter of the through hole 80 formed in the flange 75 is a rod-like shape. The diameter is substantially the same as the diameter of the shaft portion 36 b of the body main body 36.

  The sealing part main body 72 is integrally attached to the rod-shaped body main body 36 as shown in FIG. At this time, the shaft portion 36b of the rod-shaped body main body 36 is inserted into the through hole 80 of the flange portion 75, and the head portion 36a of the rod-shaped body main body 36 is brought into contact with the stepped portion formed by the two through holes 79 and 80. It is in a state.

  As shown in FIG. 11, the covering portion 73 is a cylindrical member having a cylindrical shape with a closed upper end portion, and is continuous with a space 81 formed inside by opening a lower portion. doing.

  The space 81 formed inside the covering portion 73 has a substantially mirror-like shape in which hemispherical portions whose outer shapes are flattened are stacked. Here, on the inner peripheral surface forming the edge portion of the space 81, protrusions 82 and 82 formed over the entire circumference of the inner peripheral surface are provided with an interval in the axial direction of the space 81. Yes. Each of the protrusions 82 and 82 protrudes inward from the inner peripheral surface of the space 81. More specifically, the protrusions 82 and 82 protrude substantially vertically from the radially outer side of the space 81 toward the center. ing.

  By providing the protrusions 82 and 82 as described above, the space 81 located inside the covering portion 73 becomes a flat hemispherical space 81a, which is convex upward, as shown in FIG. 81 a and 81 a are formed by being continuous in the axial direction of the covering portion 73. Here, the hemispherical space 81a is larger as the space 81a located below. That is, the lowermost space 81a is the largest, and the uppermost space 81a is the smallest.

  The connecting portion 64 is a string-like body extending in a circular cross section, and is continuous with the sealing portion main body 72 at one end portion thereof and is continuous with the covering portion 73 at the other end portion.

  In the rod-shaped body 70 of the present embodiment, the covering portion 73 can be attached to the sealing portion main body 72. More specifically, since both the covering portion 73 and the sealing portion main body 72 are formed of an elastic material, the covering portion 73 is pressed downward while being in contact with the sealing portion main body 72 from above. The main body portion 74 of the sealing portion main body 72 can be pushed into the space 81 inside the covering portion 73. That is, the protrusions 82 and the like of the covering portion 73 are temporarily deformed when pushed in, so that the protrusions 82 and 82 of the covering portion 73 can be fitted into the recesses 78 and 78 of the main body 74. Then, as shown in FIG. 11C, the protrusions 82 and 82 of the covering portion 73 are fitted into the recesses 78 and 78 of the main body portion 74, and the lower surface of the covering portion 73 contacts the upper surface of the flange portion 75. The covering portion 73 is integrally attached to the sealing portion main body 72 in a state where the upper surface of the main body portion 74 is in contact with the upper end surface on the inner side of the covering portion 73.

  When the covering portion 73 is attached to the sealing portion main body 72, the head portion 36 a of the rod-shaped body main body 36 is surrounded by the covering portion 73 and the main body portion 74 of the sealing portion main body 72. More specifically, the through-hole 79 formed in the main body portion 74 of the sealing portion main body 72 is formed in the internal space of the rod-shaped body side sealing portion 71 formed by closing the upper opening with the covering portion 73. The head portion 36a of the rod-shaped body main body 36 is accommodated. As a result, the head 36a of the rod-shaped body 36 is not exposed to the outside air.

  In addition, the rod-shaped body side sealing part and coating | coated part of this invention are not restricted to the thing of each above-mentioned embodiment. For example, the structure which does not provide a connection part may be sufficient as the rod-shaped body side sealing part of this invention. That is, the structure of only a sealing part main body and a coating | coated part may be sufficient. However, a configuration provided with a connecting portion is preferable because the covering portion is not lost when the covering portion is removed from the head portion 36a of the rod-shaped body main body 36. Moreover, this connection part does not need to be integrally formed with a coating | coated part or a rod-shaped body main body, and the structure attached to the engaging part formed in the coating | coated part or the rod-shaped body main body may be sufficient.

  Moreover, the coating | coated part of this invention is not restricted to an above-described shape. For example, the periphery of the head portion 36a of the rod-shaped body main body 36 may not be completely covered, and a part of the head portion 36a of the rod-shaped body main body 36a is exposed to the outside by forming a groove or a hole in the covering portion. Also good. In other words, it is only necessary to suppress the cooling of the head 36a by the outside air. However, a configuration that completely covers the periphery of the head portion 36a of the rod-shaped body main body 36 is desirable because cooling of the rod-shaped body main body 36 can be more reliably prevented.

  Furthermore, the shape of the covering portion is not limited to the shape described above. For example, the outer shape may be appropriately changed according to the shape of the sealing portion main body or rod-shaped body main body or the shape of the exterior member (mounting tool for solar cell module) such as a prismatic shape, a cylindrical shape, or a truncated cone shape. Moreover, you may change suitably the shape of the recessed part of a coating | coated part similarly. For example, the shape of the recess may be the same as the shape of the head of the rod-shaped body, or may be similar to the shape of the head of the rod-shaped body. Furthermore, a hemispherical shape, a prismatic shape, or a truncated cone shape may be used. That is, you may change suitably according to the shape of the head of a rod-shaped body, etc.

  Here, the embedded piece of the present invention is not limited to that of the first embodiment described above. For example, as shown in FIG. 12A, an embedded piece 88 that does not have a stepped portion on the side surface portion may be used. That is, it may be a cork-shaped embedded piece 88 whose outer shape is substantially cylindrical and whose cross-sectional diameter decreases from one end in the longitudinal direction to the other end. Moreover, the structure which provides not the through-hole 32 but the slit 88a may be sufficient. That is, the slit 88a may be widened by inserting the tip of the shaft portion 36b of the rod-shaped body main body 36 into the slit 88a and pressing the shaft portion 36b as it is. Further, as shown in FIG. 12B, an embedded piece 89 provided with a bottomed hole 89a instead of the through hole 32 may be used. That is, by inserting the shaft portion 36b of the rod-shaped body main body 36 into the bottomed hole 89a and pushing the rod-shaped body main body 36 downward, the space between the bottom portion of the bottomed hole 89a and the lower end surface of the embedded piece 89 is reduced. The structure which forms a through-hole newly may be sufficient. That is, the embedded piece employed in the fixture of the present invention may not be a cylindrical body having the through hole 32.

  Further, as shown in FIG. 12C, the diameter of one end portion in the longitudinal direction and the diameter of the other end portion may be the same. That is, the configuration may not be such that the diameter of the cross section decreases from one end to the other end. Further, the protruding piece forming the stepped portion of the embedded piece may not have a configuration in which the maximum diameter decreases from the one side end to the other end as in the first embodiment, and the maximum diameter is not limited. The embedded piece 90 may be configured such that the same protruding pieces 90a, 90a, 90a, 90a, 90a are continuously provided. That is, the protruding pieces 90a, 90a, 90a, 90a, 90a having the same maximum diameter and the embedded pieces 90 in which the groove portions 90b, 90b, 90b, 90b are alternately continued may be used. Further, the protruding piece 90a and the groove portion 90b do not have to be smoothly continuous, and the upper surface or the lower surface of the protruding piece 90a and the outermost peripheral surface located on the most central side corresponding to the bottom surface of the groove portion 90b intersect each other at a substantially right angle. Also good.

  Furthermore, as shown in FIGS. 12A to 12C, the embedded piece may have a configuration without a flange portion. That is, when inserted into the lower hole 43 of the slate roof tile 2, a portion of the embedded piece may not protrude upward from the opening of the lower hole 43. When the embedded piece employed in the present invention is inserted into the lower hole 43, the top surface of the embedded piece may be at the same height as the opening surface of the lower hole 43 or at a position lower than the opening surface.

  The fixture of the present invention may be used not only for mounting the mounting bracket of the solar cell module, but also for mounting other exterior members such as a wing. Moreover, you may use not only for the attachment of the exterior member on a roof but for the attachment of the exterior member to the outer wall of a building.
