Description

  The present invention relates to a fixing member for a folded plate roof for fixing an installation on the roof to the folded plate roof, and a mounting structure for the fixing member.

  There is a folded plate roof having a strip-like ridge portion and a pair of flat slope portions extending obliquely downward so as to be away from a pair of long sides extending in parallel with the ridge portion. . The folded plate roof has a plurality of units arranged in a direction perpendicular to the longitudinal direction of the ridge portion, with the ridge portion and the pair of slope portions as one unit. The folded plate roof is attached to the roof structural member by bolts and nuts at the ridge. The bolts and nuts protrude upward from the ridge portion with a space in the longitudinal direction. When fixing on-roof installations such as a solar cell module, a solar water heater, a greening panel, and an air conditioner outdoor unit to the folded plate roof, a fixing member for the folded plate roof as described later is used.

  As a fixing member for the folded-plate roof (hereinafter simply referred to as a fixing member), a pair of leg portions along the pair of slope portions and an upper end of the pair of leg portions are connected to the roof top installation object above the ridge portion. For example, there has been proposed a weir-like portion provided above and to the side of an attachment hole for attachment to a slope portion of a leg portion (Patent Document 1). The fixing member disclosed in Patent Document 1 can prevent rainwater flowing down the leg portion from bypassing the attachment hole by the weir-like portion and preventing rainwater from entering the attachment hole.

  However, in the technique of Patent Document 1, since the attachment portion of the fixing member is formed in a shape bent upwards near the center of the ridge portion after extending horizontally from the upper end of the slope portion onto the ridge portion, At the part where the bolt and nut protrude from the upper surface of the part, the attachment part interferes, and the fixing member cannot be attached to the part. In addition, when the fixing member is attached to the folded plate roof with a screw through the mounting hole, the head of the screw is exposed to the outside, so the head is likely to corrode depending on the material of the screw. There was a problem that the mounting strength was lowered.

  For such a problem, a pair of side plates along the pair of slope portions, a mounting portion that extends vertically upward from the upper ends of the pair of side plates, and the upper ends are connected to each other, and a covering member that covers the side plates And the fixing member provided with these is proposed (patent document 2). According to the technique of this patent document 2, since the upper end of the attachment portion is higher than the ridge portion and the attachment portion does not contact the ridge portion, the fixing member is also attached to the portion where the bolt and the nut protrude from the upper surface of the ridge portion. Can be installed. Moreover, since the cover member can cover the head of the screw with the side plate attached to the slope portion, corrosion of the head of the screw can be prevented.

  However, since the technique of Patent Document 2 does not have a portion that comes into contact with the upper surface of the ridge portion, only the pair of side plates attached to the pair of slope portions are used to load the load from the rooftop installation object or the like. Since it receives, a load acts on the side plate in the direction along the slope portion, and a large shear load is applied to the screw. Therefore, there is a problem that the screw is easily broken and the mounting strength of the fixing member is weakened. Moreover, in the technique of patent document 2, since the cover member is inserted in the insertion groove formed in the side plate so as to face each other, and the cover member is attached, an object flying during a typhoon or the like is covered by the cover member. In this case, the covering member is deformed and detached from the fitting groove, and there is a problem that the removed covering member may injure a person or damage other members. In addition, when the cover member is removed, the head of the screw is exposed, so that the head of the screw is corroded and the mounting strength of the fixing member is lowered.

  Then, this invention makes it a subject to provide the fixing member for folding plate roofs for fixing the installation object on a roof which can raise the attachment strength to a folded plate roof, and the attachment structure of a fixing member in view of said situation. Is.

  In order to solve the above-mentioned problem, the fixing member for folded plate roof according to the present invention is "beveled downward so that the strip plate-like ridge portion and a pair of long sides extending in parallel with the ridge portion are separated from each other. And a pair of flat slopes extending to the folding plate roof, the folding plate roof fixing member for fixing the installation on the roof, a pair below the ridge portion A pair of flat plate-shaped fixing portions that respectively contact the slope portions, a pair of flat plate-shaped leg portions that extend from the upper side of the pair of fixing portions to above the ridge portion, and above the ridge portion, respectively. A pair of plate-like connecting portions connecting the middle portions of the pair of leg portions, a pair of positioning portions provided immediately above a pair of long sides of the ridge portion on the upper surface of the connecting portion, and a pair of the above-mentioned The upper sides of the leg portions are connected to each other, and the fixed portion is mounted on the placement portion on which the installation object on the roof is placed and a pair of the leg portions. And a pair of draining portions extending obliquely downward toward the upper part of the part, the whole extending with a constant cross-sectional shape, and the bolts and nuts attaching the folded plate roof to the roof structure member pass And a long hole-like through-hole that penetrates the connecting portion in the center in the longitudinal direction and is long in the longitudinal direction, and at a certain distance from the both ends in the longitudinal direction of the pair of fixing portions toward each other. Each of the through holes, a mounting hole through which a screw for mounting on the folded plate roof is inserted, and the pair of fixing portions are in contact with the pair of slope portions, and the connecting portion is in contact with the ridge portion, In the state where the fixing part is attached to the folded plate roof by the screw passing through the attachment hole, a belt-like waterproof tape attached to at least the surface of the fixing part so as to cover the screw is provided. It is characterized by That.

  Here, as "folded plate roof", in addition to the ridge portion and a pair of slope portions, those having a valley portion connecting the lower sides of the adjacent slope portions, " What has the goby part which protrudes upwards from a ridge part can be illustrated. Further, examples of the “on-roof installation” include “solar cell module”, “solar water heater”, “greening panel”, “air conditioner outdoor unit”, and “roofing floor material”.

  In addition, the “mounting portion” is “open to the placing surface with a width through which the mounting surface on which the roof edge installation object is placed and the male screw portion of the mounting bolt for attaching the installation object on the roof are inserted. And an enlarged portion that is communicated with the opening and that is wider than the opening and into which a nut that is screwed into the head of the mounting bolt or the male screw is non-rotatably inserted. Having a holding groove extending in the longitudinal direction with a cross-section having an inverted T-shape ”,“ a mounting surface on which the installation object on the roof is mounted, and projecting upward from the mounting surface ” Having a male thread part to which a nut for mounting the installation object on the roof is screwed, "a mounting surface on which the installation object on the roof is mounted, and a mounting surface Having a female screw hole into which a male screw portion of a mounting bolt for mounting an installation on the roof is screwed ”,“ on-roof installation Having a mounting surface to be mounted and a mounting hole penetrating the mounting surface and through which a male screw part of a mounting bolt for mounting an installation on the roof is inserted "," on the roof There are a mounting surface on which the installation object is mounted, a flat mounting wall protruding upward from the mounting surface, and a male screw portion of a mounting bolt that penetrates the mounting wall and mounts the installation object on the roof. What has a mounting hole to be inserted "can be exemplified.

  Furthermore, examples of the “position determining portion” include “a groove recessed from the upper surface of the connecting portion” and “a protrusion protruding from the upper surface of the connecting portion”. Further, the positioning portion may be formed over the entire length in the longitudinal direction of the connecting portion, or may be formed only near both ends in the longitudinal direction of the connecting portion.

  In addition, “waterproof tape” includes “butyl rubber tape”, “foamed EPDM (ethylene / propylene / diene rubber) tape”, “vinyl tape”, “foamed EPM (ethylene / propylene rubber) tape”, “silicone tape”, Can be illustrated.

  The fixing member for the folded-plate roof of this structure makes a pair of fixing | fixed part contact | abut to the slope part of the both sides of the ridge part in a folded-plate roof, and makes the lower surface of a connection part contact | abut to a ridge part. Further, the pair of positioning portions on the upper surface of the connecting portion is positioned immediately above the pair of long sides of the ridge portion. In this state, after screwing the screw into the folded plate roof through the mounting hole penetrating the fixed portion, affixing the waterproof tape to the surface of the fixed portion so as to cover the screw, the fixed member is attached to the folded plate roof. Can be installed. And an installation thing on a roof can be fixed to a folded-plate roof by mounting and attaching an installation object on a roof to the mounting part of the fixing member attached to the folding-plate roof.

  Thus, according to the fixing member of this configuration, since the connecting portion is in contact with the ridge portion of the folded plate roof, the connecting portion in which the load from the installation object on the roof is in contact with the ridge portion. Therefore, it hardly acts on the pair of fixed portions that are in contact with the pair of slope portions. Accordingly, since the load acting on the fixed portion in the direction along the slope portion is reduced, the shear load acting on the screw attaching the fixed portion to the slope portion is also reduced, and the screw is difficult to break. While being able to do, the attachment strength of the fixing member with respect to a folded-plate roof can be raised.

  In addition, since the fixing member of this configuration has a waterproof tape attached to at least the surface of the fixing portion so as to cover the head of the screw, the rainwater or the like does not contact the screw, and the screw corrodes by rainwater or the like. This can be prevented, and a reduction in the mounting strength of the fixing member can be avoided. In addition, since the member that covers the screw is made of waterproof tape, and the waterproof tape has flexibility, even if the waterproof tape is peeled off for some reason, the peeled waterproof tape can damage people or damage other members. It can be made highly safe. Furthermore, when the waterproof tape is applied, it is possible to prevent rainwater or the like from coming into contact with the upper side of the waterproof tape by the drainage portion by attaching the waterproof tape so that the upper side is positioned below the drainage portion. . Thereby, it is possible to prevent rainwater or the like from entering between the fixing portion and the waterproof tape, and the waterproof tape is difficult to peel off.

  By the way, in the technique of patent document 1, when the site | part for attaching to the fixing member in an installation on a roof corresponds with the site | part which the volt | bolt and nut in a folded-plate roof have protruded, it is a fixing member in the said site | part in a folded-plate roof. Can not be installed. Therefore, in the technique such as Patent Document 1, first, the two fixing members are mounted apart from each other in the flow direction of the folded plate roof, avoiding the portion where the bolt and the nut protrude. And after attaching the crosspiece member of the length which can attach an installation object on a roof by the length which straddles them to two fixing members, the installation object on a roof is attached to the crosspiece member. Therefore, in the technique of Patent Document 1, when fixing the installation on the roof to the folded plate roof, a crosspiece member is required in addition to the fixing member, the number of parts increases, the fixing work becomes complicated, and the cost is increased. There are increasing problems.

  On the other hand, the fixing member of this configuration forms a through-hole through which a bolt and a nut that attach the folded plate roof to the roof structure material pass in a connecting portion that contacts the ridge portion of the folded plate roof. By inserting the bolt and nut through the through hole, the fixing member for the folded plate roof can be attached to the portion where the bolt and nut protrude. Therefore, even if the site | part for attaching to the fixing member in an installation on a roof corresponds with the site | part which the volt | bolt and nut in a folded-plate roof protrude, a fixing member can be attached to the said site | part of a folded-plate roof. Therefore, it is possible to fix the installation on the roof with a fixing member without using a cross member as in the technique of Patent Document 1, and to facilitate the fixing operation of the installation on the roof, An increase in cost can be suppressed.

  Moreover, since the fixing member of this structure can be attached to the part attached to the roof structure member in the folded-plate roof, that is, the part where the bolt and the nut protrude from the ridge portion, the fixing member is attached to the part. By attaching, the load of the installation on the roof can be directly applied to the roof structure member via the fixing member and the folded plate roof, and the load on the folded plate roof can be reduced. The fixed strength of the installation on the roof can be high.

  Moreover, the fixing member for folded plate roof according to the present invention, in addition to the above configuration, further includes “a waterproof sheet attached to at least the back surface of the fixing portion so as to cover the outer periphery of the mounting hole. It may also be characterized by

  Here, examples of the “waterproof sheet” include “butyl rubber sheet”, “urethane rubber sheet”, and “silicone rubber sheet”. In addition, as a part where the waterproof sheet is pasted, “only around the mounting hole on the back surface of the fixing portion”, “entire surface of the back surface of the fixing portion”, “end portions of the fixing portion, the leg portion, and the connecting portion in the longitudinal direction Can be exemplified by “a portion having a certain width including the mounting hole”.

  According to this configuration, since the waterproof sheet is attached to the back surface of the fixing portion at the attachment hole portion, when the fixing member is attached to the folded plate roof, the screw inserted through the attachment hole penetrates the waterproof sheet. It is screwed into the folded plate roof, and the space between the screw and the sloped portion of the folded plate roof is sealed watertight with a waterproof sheet. Thereby, it can prevent that rainwater etc. penetrate | invade via a screw | thread from the surface side to the back surface side of a folded-plate roof, and the performance of a folded-plate roof is not impaired.

  The mounting structure of the fixing member for the folded-plate roof according to the present invention is as follows: "A pair of ridge portions that are strip-shaped and a pair of long sides extending in parallel so that the ridge portions extend away from each other. A mounting structure of a fixing member for a folded-plate roof that fixes an installation on the roof to a folded-plate roof having a flat slope portion, and the fixing member is more than the ridge portion. A pair of flat plate-like fixing portions that are respectively in contact with the pair of slope portions at a lower side, and a pair of flat plate-like leg portions that respectively extend upward from the ridges from the upper sides of the pair of fixing portions. A flat plate-like connecting portion that is in contact with the ridge portion from above and connects the middle portions of the pair of leg portions, and is provided immediately above the pair of long sides of the ridge portion on the upper surface of the connecting portion. The pair of positioning portions and the upper sides of the pair of legs are connected to each other, and the installation object on the roof is Comprising a placing portion to be placed and a pair of draining portions respectively extending obliquely downward from the pair of leg portions toward the upper side of the fixed portion, and the whole extends with a constant cross-sectional shape, Bolts and nuts that attach the folded plate roof to the roof structural member pass, penetrate through the connecting portion in the center in the longitudinal direction, and are elongated in the longitudinal direction and a pair of the fixing portions In both of the longitudinal direction of the two in the direction of approaching each other at a fixed distance, a mounting hole through which a screw attached to the folded plate roof is inserted, and the fixing hole is inserted through the mounting hole A belt-like waterproof tape affixed to at least the surface of the fixed part so as to cover the screw to which the part is attached. "

  This structure is a fixing member mounting structure formed by attaching the above-mentioned fixing member for the folded-plate roof to the folded-plate roof, and exhibits the above-described effects and is attached to the folded-plate roof via the fixing member. The installation on the roof can be fixed.

  As described above, as an effect of the present invention, it is possible to provide a fixing member for a folded plate roof and an attaching structure for the fixing member for fixing an installation on the roof that can increase the attachment strength to the folded plate roof. .

  The placement portion 16 has a width direction length (width) larger than a width (a distance between a pair of long sides) of a ridge portion 1a of the folded plate roof 1 described later. The mounting portion 16 has an opening at the center in the width direction of the upper surface, and has a holding groove 16a having a reverse T-shaped cross section in the width direction. The holding groove 16a is inserted into the head 31b of the root bolt 31 so that a male screw portion 31a of a root bolt 31 to be described later for attaching the solar cell module 30 protrudes upward from the upper surface. Can be held in a non-rotatable manner around the axis of the male screw portion 31a, and can be held so as to be slidable in the longitudinal direction (see FIG. 5A). The mounting portion 16 is connected to the upper sides of the pair of leg portions 12 at a portion below the holding groove 16a.

  The pair of draining portions 17 extends obliquely downward from a portion of the leg portion 12 opposite to the portion connected by the connecting portion 13. The through hole 18 is formed in the center of the connecting portion 13. The through hole 18 has the same width direction as the width of the mounting portion 16, and the longitudinal direction is half the total length of the fixing member 10. The through hole 18 has a length in the longitudinal direction such that the distance from the longitudinal end of the connecting portion 13 to the through hole 18 is larger than the width in the flow direction of the roof mounting member 2 described later. The through-hole 18 is sized to allow a cap 5 (a member indicated by a two-dot chain line in FIGS. 2 and 3) covering the bolt 3 and the nut 4 protruding from the folded plate roof 1 described later.

  Two attachment holes 19 are formed in one fixing portion 11. The mounting hole 19 is formed at a position from the longitudinal end of the fixing member 10 to the longitudinal end of the through hole 18 with respect to the longitudinal direction of the fixing member 10. Furthermore, the attachment hole 19 is formed at a position at a distance of 1/8 of the entire length of the fixing member 10 from the longitudinal end of the fixing portion 11 at the center in the vertical direction of the fixing portion 11.

  The pair of fixed range identifying portions 20 is configured by a line extending upward from the lower side of the fixed portion 11 along the surface of the fixed portion 11 on the surface of the fixed portion 11. The pair of fixed range identifying units 20 are provided symmetrically with respect to the center in the longitudinal direction of the fixed unit 11.

After the cutting, the through hole 18 and the mounting hole 19 are punched, and the fixed range identifying portion 20 and the central identifying portion 21 are engraved. In the present embodiment, the waterproof tape 22 is a butyl rubber-based tape having an adhesive layer on one side, and the waterproof sheet 23 is a butyl rubber sheet.

  As shown in FIGS. 2 to 4 and the like, the folded plate roof 1 extends obliquely downward so as to be away from each other from a strip plate-like ridge portion 1a and a pair of long sides extending in parallel with the ridge portion 1a. A pair of flat slope portions 1b, and a direction in which the long side of the ridge portion 1a extends with the ridge portion 1a and the pair of slope portions 1b as a unit (a direction perpendicular to the paper surface in FIG. 2). In the following description, a plurality of units are arranged in a direction perpendicular to the flow direction (left and right direction in FIG. 2 and hereinafter referred to as the horizontal direction). Moreover, the folded-plate roof 1 has the strip | belt-plate-shaped trough part 1c which has connected the lower sides of the two slope parts 1b located between the ridge parts 1a. The folded plate roof 1 is formed by bending a metal plate.

  The folded plate roof 1 is attached to a roof attachment member 2 constituting a part of the roof structure member via bolts 3 and nuts 4. The roof mounting member 2 is formed by bending a band plate material in a zigzag manner along the lower surface of the folded plate roof 1, and a bolt protruding upward at a portion where the lower surface of the ridge portion 1 a of the folded plate roof 1 abuts. 3 is attached. The folded plate roof 1 is attached to the roof attachment member 2 by screwing and tightening a nut 4 to a bolt 3 penetrated from below in the ridge portion 1a. In the folded plate roof 1, as shown by a two-dot chain line in FIGS. 2 and 3, a cap 5 may be attached to the bolt 3 and the nut 4 protruding from the ridge portion 1a.

  The solar cell module 30 as an installation on the roof has a module main body 30a and mounting claws 30b protruding from two sides extending in parallel with the module main body 30a. The attachment claw 30 b is for attaching the solar cell module 30 to the fixing member 10. Although the solar cell module 30 will be described in detail later, the male screw portion 31a of the root bolt 31 that protrudes upward from the placement portion 16 in a state where it is placed on the placement portion 16 of the fixing member 10, and the male screw portion A pressing member 32 through which 31a penetrates and whose lower end is in contact with the mounting claw 30b from above, and a nut that presses the pressing member 32 downward by being screwed into the male screw portion 31a from above the pressing member 32 and tightening 33 to the fixing member 10.

  Next, the fixing method which fixes the solar cell module 30 to the folded-plate roof 1 using the fixing member 10 of this embodiment is demonstrated. First, an attachment line indicating a position (a position of the root bolt) that extends in the lateral direction of the roof and is spaced apart in the flow direction is fixed on the folded plate roof 1. In FIG. 5, for the sake of convenience, an alternate long and short dash line passing through the attachment line is referred to as an attachment line L. And the fixing member 10 is mounted and attached to the folded-plate roof 1 from the one side (here eaves side) of the flow direction.

  The fixing member 10 is placed on the folded plate roof 1 in such a way that the fixing member 10 is bonded to the pair of fixing portions 11 with the longitudinal direction of the fixing member 10 parallel to the flow direction of the folded plate roof 1. Through the sheet 23, the two protruding portions 14 protruding from the lower surface of the connecting portion 13 are brought into contact with the ridge portion 1 a while being brought into contact with the slope portions 1 b on both sides of the ridge portion 1 a in the folded plate roof 1. At this time, the central identification portion 21 provided on the upper surface of the placement portion 16 is made to coincide with the attachment line L marked on the folded plate roof 1 and a pair of positioning portions 15 on the upper surface of the connecting portion 13. Is positioned directly above the pair of long sides of the ridge 1a.

  When the fixing member 10 is placed on the folded plate roof 1 in this way, the screws 24 are screwed into the folded plate roof 1 and tightened through the attachment holes 19 of the fixed portion 11. Thereafter, the waterproof tape 22 is applied from the lower part of the leg part 12 to the fixing part 11 so as to cover the head of the screw 24 exposed on the surface of the fixing part 11. When the waterproof tape 22 is applied, the upper side of the waterproof tape 22 is applied in a state of being inserted between the leg portion 12 and the draining portion 17. By doing in this way, the fixing member 10 will be in the state attached to the folded-plate roof 1, and the attachment structure of the fixing member 10 is constructed | assembled.

  When a necessary number of fixing members 10 are attached to one attachment line L, the fixing member 10 is applied to the next attachment line L separated from the attachment line L in the flow direction by the same procedure as described above. Is attached to the folded roof 1.

  By the way, in the flow direction of the folded plate roof 1, the bolt 3 and the nut 4 protrude due to the difference between the interval at which the bolt 3 and the nut 4 protrude and the interval between the attachment lines L depending on the size of the solar cell module 30. The attachment line L may pass in the vicinity of the part (see FIG. 5). In such a case, the fixing member 10 is attached to the folded plate roof 1 so that the attachment line L is located between the pair of fixing range identifying portions 20 of the fixing member 10. At this time, when the distance between the mounting line L and the portion where the bolt 3 and the nut 4 protrude in the folded plate roof 1 is narrower than the distance between the pair of fixed range identifying portions 20, as shown in FIG. Further, the fixing member 10 is attached to the folded plate roof 1 such that the bolt 3 and the nut 4 protruding from the folded plate roof 1 are inserted into the through hole 18 of the fixing member 10.

  Or when the attachment line L can be located between a pair of fixed range identification part 20, as shown in FIG.5 (b), from the site | part which the volt | bolt 3 and the nut 4 in the folded-plate roof 1 protrude. Alternatively, the fixing member 10 may be attached to the folded plate roof 1 outside the flow direction.

  When the plurality of fixing members 10 are attached to the folded plate roof 1 in this way, the solar cell modules 30 are placed in order from the eaves side on the placement portion 16 of the fixing members 10 and attached to the fixing member 10. Specifically, the head 31 b of the root bolt 31 with the head 31 b down is inserted into the holding groove 16 a of the mounting portion 16 from the longitudinal end of the fixing member 10 and coincides with the attachment line L. Slide to position. Then, the root bolt 31 is fixed to the mounting portion 16 by screwing the nut 34 into the male screw portion 31a of the root bolt 31 protruding upward from the upper surface of the mounting portion 16 and tightening the nut 34 (FIG. 5A). )).

  In a state where the root bolt 31 is fixed to the fixing member 10, the end of the solar cell module 30 is placed on the placement portion 16, the solar cell module 30 is slid in the flow direction, and the attachment claw 30 b is attached to the root corner bolt 31. It is made to approach the male screw part 31a. Then, the male screw part 31a of the root bolt 31 is covered with the pressing member 32 so that the upper end of the male screw part 31a protrudes upward through the pressing member 32 and the lower end of the pressing member 32 is brought into contact with the mounting claw 30b. In this state, the nut 33 is screwed into the male screw portion 31a of the root bolt 31 and tightened, whereby the pressing member 32 presses the mounting claw 30b against the mounting portion 16, and the solar cell module 30 is attached to the fixing member 10. It is done.

  By the way, when attaching the several solar cell module 30 to a flow direction, as shown to Fig.5 (a), the external thread part 31a of the root bolt 31 which protrudes upwards from the mounting part 16 of the fixing member 10 is interposed. Thus, the pressing member 32 is straddled between the mounting claws 30b of the eaves-side solar cell module 30 and the mounting claws 30b of the ridge-side solar cell module 30, and the solar cell modules on both sides are formed by one pressing member 32.

  In this way, by attaching the solar cell module 30 to the plurality of fixing members 10 attached to the folded plate roof 1, the solar cell module 30 as the installation object on the roof can be fixed to the folded plate roof 1. .

  Thus, according to the fixing member 10 of this embodiment, since the two protrusion parts 14 which protrude from the connection part 13 contact | abut to the ridge part 1a of the folded-plate roof 1, the installation thing on a roof As a result, the load from the solar cell module 30 acts on the connecting portion 13 via the protruding portion 14 that is in contact with the ridge portion 1a, and the pair of fixed portions 11 that are in contact with the pair of slope portions 1b. Has little effect. Accordingly, since the load acting on the fixed portion 11 in the direction along the slope portion 1b is reduced, the shear load acting on the screw 24 that attaches the fixed portion 11 to the slope portion 1b is also reduced. It is possible to make it difficult to break, and to increase the attachment strength of the fixing member 10 to the folded plate roof 1.

  Further, since the fixing member 10 of the present embodiment has the waterproof tape 22 applied so as to cover the head of the screw 24, the rain water or the like does not contact the screw 24, and the screw 24 corrodes due to the rain water or the like. This can be prevented, and a reduction in the mounting strength of the fixing member 10 can be avoided. Further, since the upper side of the waterproof tape 22 is inserted between the leg portion 12 and the draining portion 17, the draining portion 17 can prevent contact of rainwater or the like with the upper side of the waterproof tape 22, and is waterproof. Peeling of the tape 22 can be suppressed.

  Further, in the fixing member 10 of the present embodiment, the member that covers the screw 24 is the waterproof tape 22, and the waterproof tape 22 has flexibility. Therefore, even if the waterproof tape 22 is peeled off for some reason, it is peeled off. The waterproof tape 22 does not hurt people or damage other members, and can be made highly safe.

  Furthermore, the fixing member 10 of this embodiment attaches the folded-plate roof 1 to the roof mounting member 2 as a roof structure material to the connection part 13 which contact | abuts the ridge part 1a of the folded-plate roof 1 via the protrusion part 14. FIG. Since the through-hole 18 through which the bolt 3 and the nut 4 pass is formed, by inserting the bolt 3 and the nut 4 through the through-hole 18, the fixing member 10 is also applied to the portion where the bolt 3 and the nut 4 protrude. Can be installed. Therefore, even if the attachment claw 30b (attachment line L for attachment) of the solar cell module 30 coincides with the part where the bolt 3 and the nut 4 protrude from the folded plate roof 1, it is fixed to the part of the folded plate roof 1. Since the member 10 can be attached, the eaves-side mounting claw 30b and the ridge-side mounting claw 30b of the solar cell module 30 are fixed by the fixing member 10 without using a crosspiece member as in the prior art. The solar cell module 30 can be easily fixed, and an increase in cost can be suppressed.

  Moreover, the fixing member 10 of this embodiment attaches the fixing member 10 to the site | part attached to the roof attachment member 2 in the folded-plate roof 1, ie, the site | part which the volt | bolt 3 and the nut 4 protrude from the ridge part 1a. Therefore, by attaching the fixing member 10 to the portion of the folded plate roof 1, the load of the solar cell module 30 is directly applied to the roof mounting member 2 via the fixing member 10 and the folded plate roof 1. Thus, the load on the folded plate roof 1 can be reduced, and the fixing strength of the solar cell module can be increased.

  Furthermore, since the fixing member 10 of the present embodiment has the protruding portion 14 protruding from the lower surface of the connecting portion 13 in contact with the ridge portion 1a of the folded plate roof 1, the protruding portion 14 and the connecting portion 13 are in contact with each other. Since a gap can be formed between the ridge portion 1a, rainwater or the like flowing down the ridge portion 1a can be caused to flow toward the eaves. Further, since the waterproof sheet 23 is attached only to the portion of the attachment hole 19 on the back surface of the fixing portion 11, when the fixing member 10 is attached to the folded plate roof 1, the two are separated in the longitudinal direction. Between the two mounting holes 19, a gap is formed between the fixed portion 11 and the slope portion 1 b due to the presence of the waterproof sheet 23, so that rainwater or the like flows from the ridge portion 1 a side to the fixed portion 11 and the slope portion 1 b. Even if it intrudes, it can flow downward of the slope 1b through the gap. For this reason, it is possible to prevent rainwater and the like from being accumulated in the fixing member 10, so that the fixing member 10 and the folded plate roof 1 can be prevented from being corroded by the accumulated rainwater and the like.

  Moreover, since the waterproof sheet 23 is affixed to the back surface of the fixing | fixed part 11 in the site | part of the attachment hole 19, the fixing member 10 of this embodiment is attached to the attachment hole 19 when attaching the fixing member 10 to the folded-plate roof 1. FIG. The inserted screw 24 passes through the waterproof sheet 23 and is screwed into the folded roof 1 so that the waterproof sheet 23 can seal the space between the screw 24 and the inclined surface 1b of the folded roof 1 in a watertight manner. Therefore, it is possible to prevent rainwater or the like from entering the screw 24 from the front surface side to the back surface side of the folded plate roof 1, and the performance of the folded plate roof 1 is not impaired.

  Moreover, since the fixing member 10 of the present embodiment has the holding groove 16a of the mounting portion 16 extending over the entire length of the fixing member 10, the position of the root bolt 31 for attaching the solar cell module 30 is maintained. It can be freely moved within the range of the length of the groove 16a. Thereby, even if the position which attaches the fixing member 10 with respect to the folded-plate roof 1 is somewhat shifted | deviated, the root bolt 31 can be slid in the mounting part 16 to an appropriate position, and the mounting position shift | offset | difference of the fixing member 10 is possible. Can be absorbed.

  Moreover, since the fixing member 10 of this embodiment has a pair of fixed range identification part 20, it is a solar cell by fixing the solar cell module 30 by using between the pair of fixed range identification parts 20 as a standard. It is possible to avoid the load from the module 30 being biased to one side in the longitudinal direction of the fixing member 10, and the solar cell module 30 can be fixed in a stable state.

  Furthermore, the fixing member 10 of the present embodiment connects the middle and upper side of the pair of leg portions 12 with the connecting portion 13 and the mounting portion 16, and the fixing member 10 includes a cylindrical portion. Therefore, the strength / rigidity of the fixing member 10 is increased, and even when a large load is applied from the solar cell module 30 side, the fixing member 10 is not easily deformed, and the solar cell module 30 can be fixed to the folded roof 1 with high fixing strength.

  By the way, as shown in FIG.2 and FIG.3, since the thickness of the roof mounting member 2 is more than double the thickness of the folded-plate roof 1, when screwing a screw in the roof mounting member 2, it is necessary to open a pilot hole. There is. And the fixing member 10 of this embodiment makes the distance from the edge part of the longitudinal direction of the connection part 13 to the through-hole 18 larger than the width | variety of the flow direction of the roof attachment member 2, and the attachment hole 19 is made. Since the fixing member 10 is formed at a position between the longitudinal end of the fixing member 10 and the longitudinal end of the through hole 18 with respect to the longitudinal direction of the fixing member 10, the mounting hole 19 is formed on the roof mounting member 2. The fixing member 10 cannot be placed on the folded-plate roof 1 so as to overlap. Accordingly, when the fixing member 10 is attached to the folded roof 1, the attachment hole 19 does not overlap the roof attachment member 2, so there is no need to open a pilot hole for screwing the screws 24 into the roof attachment member 2. The attachment work of the member 10 can be made easy.
