Description

The present invention relates to a wire rod pull-in structure and a wire rod pull-in tool in which a wire rod is pulled into a building from above the roof material via a wire rod pull-in tool.

In the past, the applicant has applied electric wires from the solar cell module, antenna wires from the TV antenna, etc. from the roofing material laid on the roof structure such as rafters and field boards that make up the roof of the building into the building. We have proposed a wire rod pulling tool for pulling in a wire rod (Patent Document 1 and Patent Document 2). These wire drawing tools include a container-shaped main body member whose upper end surface and eaves side end surface are open, and a lid member that covers the upper part of the main body member. The main body member has an insertion hole that penetrates vertically inside the container shape.

In the attachment of the wire rod retractor to the roof material, first, the main body member is attached to the roof material so that the insertion holes match the through holes formed in the roof structure and the roof material. Then, the wire rod is introduced into the main body member from the eaves side end face and extends into the building through the insertion hole and the through hole. After that, by attaching the lid member to the main body member from above, the drawing of the wire rod and the attachment of the wire rod pulling tool are completed. In this way, by pulling the wire into the building through the wire pulling tool, rainwater that has traveled through the wire can be prevented from entering the building.

In the above-mentioned wire rod pulling tool, a tubular member or a cylinder for preventing the wire rod from coming into contact with the roof structure and the through hole formed in the roof material and preventing rainwater from entering below the roof structure. It has a shaped part. Specifically, the wire rod retracting tool of Patent Document 1 has a tubular sleeve material that is inserted into the through hole from above the main body member through the insertion hole. Further, in the wire rod retracting tool of Patent Document 2, a tubular guide portion to be inserted into the through hole is integrally provided with the main body member.

However, in the technique of Patent Document 1, if the main body member is attached to the roofing material in a state where the insertion hole of the main body member is deviated from the through hole, there is a risk that the sleeve material cannot be inserted. Further, in the technique of Patent Document 1, since the sleeve material is inserted into the insertion hole and the through hole from above the main body member, the lid member can be attached to the main body member even when the sleeve material is insufficiently inserted. Therefore, if it is installed in such a state, rainwater may infiltrate into the building through between the sleeve material and the insertion hole and the through hole.

On the other hand, in the technique of Patent Document 2, when the through hole is formed so as to be tilted from the direction perpendicular to the upper surface of the roof material, when the guide portion is inserted into the through hole and the main body member is mounted on the roof material, the main body member There was a risk that the lower surface would be tilted with respect to the upper surface of the roofing material, making it impossible to attach the main body member to the roofing material.

For this reason, in the conventional techniques such as Patent Document 1 and Patent Document 2, it is necessary to carefully perform the work of attaching the main body member and the work of drilling through holes in the roof structure and the roof material. It took time and effort to pull in the wire.

Japanese Patent No. 4869141 Japanese Patent No. 5586574

Therefore, in view of the above circumstances, it is an object of the present invention to provide a wire rod pull-in structure and a wire rod pull-in tool that prevent rainwater from entering the building and facilitate the wire rod pull-in work.

In order to solve the above problems, the wire rod lead-in structure according to the present invention is a wire rod lead-in structure in which the wire rod is drawn into the building from above the roof material laid on the roof structure via the wire rod pull-in tool. The wire rod retracting tool includes a guide member having a tubular guide portion penetrating the roof material and the roof structure, and a flange portion extending outward from the upper end of the guide portion. , A flat plate-shaped substrate portion mounted on the roofing material so as to cover the upper part of the guide member, an opening larger than the diameter of the flange portion and penetrating the substrate portion into which the flange portion is inserted. The opening is opened in a state where the portion, the protrusion extending inward from the inner peripheral surface of the opening and extending upward from the flange, and the eaves extending upward from the substrate portion. The wire rod includes a main body member having a surrounding peripheral wall portion and a lid member attached to the main body member that covers the peripheral wall portion from the outside and closes the peripheral wall portion from above. , It is introduced from the eaves side into the peripheral wall portion, and is drawn into the building through the opening and the guide portion. "

Here, examples of the "roof structure" include field boards and rafters. Moreover, as a "roofing material", a sheet metal roofing material, a slate, an asphalt single, and a roof tile can be exemplified.

In addition, "wires" include "electric wires connected to solar cell modules, wind power generators, commercial power lines, lighting devices, etc.", "antenna wires connected to antennas", "telephones, the Internet, cable TV, etc." Examples thereof include "connected communication lines", "water distribution pipes connected to solar water heaters, sprinklers, etc.", "pipes connected to air conditioners", and "other pipes such as gas pipes".

In the wire rod lead-in structure of this configuration, the guide member is inserted from above into the roofing material and the through hole formed in the roof structure, and the main body member is moved upward so that the flange portion at the upper end of the guide member is fitted into the opening. Install on the roofing material. Then, the wire rod is extended from the open eaves side of the peripheral wall portion to the inside of the main body member, and is drawn into the building through the opening and the guide member, and the lid member is attached to the main body member from above. Can be done.

According to the wire rod lead-in structure of this configuration, the opening of the main body member has a protrusion extending above the flange of the guide member, so that the guide portion cannot be sufficiently inserted into the through hole. Even if the collar portion protrudes upward from the roof material, the protrusion can abut on the collar portion and press the guide member downward when the main body member is mounted on the roof material. As a result, the guide portion can be sufficiently inserted into the through hole, and rainwater can be prevented from entering the building through the guide member and the through hole.

Further, according to the wire rod lead-in structure of the present configuration, since the guide member is a separate member located below the main body member, it is inserted into the through hole of the roofing material and the roof structure and protrudes onto the roofing material. The main body member may be placed on the roof material so that the opening is fitted to the flange portion of the guide member, and the attachment work of the main body member can be facilitated. Further, since the guide member is a separate member from the main body member, the main body member can be mounted on the roofing material even if the through hole is tilted from the direction perpendicular to the upper surface of the roofing material, and the drilling work as in the conventional case. You don't have to be careful.

Further, in the wire rod lead-in structure according to the present invention, in addition to the above configuration, "the lid member is inclined so as to approach the substrate portion toward the eaves side".

By the way, in the wire rod lead-in structure, the inside of the wire rod lead-in tool through which the wire rod is inserted communicates with the inside of the building through the opening of the main body member and the guide member, so that the opening and the guide member are passed through when the temperature of the outside air is low. When warm air in the building is introduced into the wire pull-in tool, dew condensation occurs inside the wire lead-in tool. At this time, if the slope of the roof to which the wire drawing tool is attached is gentle, it becomes difficult for the condensed water inside the lid member to flow toward the eaves, and it becomes water droplets and falls into the building through the opening and the guide member. There is a risk that it will end up.

According to the wire drawing structure of this configuration, the lid member is inclined so that the eaves side is lower than the substrate portion of the main body member, so that the water condensed inside the lid member can easily flow toward the eaves. It is possible to prevent the condensed water from falling toward the opening. Therefore, even when the wire rod lead-in structure of this configuration is constructed on a roof with a gentle slope, it is possible to prevent the water condensed inside the wire rod lead-in tool from falling into the building.

The wire rod pulling tool according to the present invention covers "a guide member having a tubular guide portion and a flange portion extending outward from the upper end of the guide portion, and an upper portion of the guide member. A flat substrate portion, an opening that is larger than the diameter of the flange portion and penetrates the substrate portion and into which the collar portion is inserted, and an opening that protrudes inward from the inner peripheral surface of the opening portion. A main body member having a protrusion extending upward and a peripheral wall portion extending upward from the substrate portion and surrounding the opening in a partially opened state, and the main body member. It is attached and includes a lid member that covers the peripheral wall portion from the outside and closes the peripheral wall portion from above. "

The wire rod pulling tool having this configuration is used for the above wire rod pulling structure. This wire drawing tool is used with the open part of the peripheral wall facing the eaves side. Further, since the protrusion is extended inward from the inner peripheral surface of the opening in the main body member, when the wire rod retracting tool is attached, if the guide portion is not sufficiently inserted into the through hole, the protrusion Can abut on the collar and press the guide member downward. In this way, by using this wire rod pulling tool to pull the wire rod into the building, the above-mentioned action and effect are exhibited. In addition, since the wire pulling tool of this configuration uses the guide member as a separate member from the main body member, a mold for molding the main body member is required as compared with the case where the guide member and the main body member are integrated. It can be made smaller, and an increase in manufacturing cost can be suppressed.

As described above, as an effect of the present invention, it is possible to provide a wire rod drawing structure and a wire rod drawing tool that can prevent rainwater from entering the building and facilitate the wire rod drawing work.

It extends to the vicinity of the long side of the portion 12a. Then, the substrate portion 12a is bent near the long side and extends parallel to the long side to the eaves side short side 12c. On the upper surface of the peripheral wall portion 12g, screw holes 12h for attaching the lid member 13 are formed in the vicinity of the end portion close to the ridge side short side 12b and the vicinity of the end portion close to the eaves side short side 12c.

Further, the main body member 12 has a pair of first weir portions 12i and a second weir portion 12j. The first weir portion 12i extends upward from the substrate portion 12a below the peripheral wall portion 12g between the opening 12d and the eaves side short side 12c, respectively, inside the peripheral wall portion 12g. The second weir portion 12j extends upward from the substrate portion 12a on the eaves side short side 12c side of the pair of first weir portions 12i, lower than the peripheral wall portion 12g.

The pair of first weir portions 12i extend diagonally so as to approach the eaves side short side 12c toward the center side in the width direction from the inner peripheral surface of the portion extending in parallel in the peripheral wall portion 12g. The pair of first weir portions 12i has a free end at the central end in the width direction. The pair of first weir portions 12i is formed so that the portion included in the range when the opening portion 12d is projected in the longitudinal direction is lower in height than the portion outside the portion. The high portion of the pair of first weir portions 12i is 3/4 of the height of the peripheral wall portion 12g, and the low portion is 1/3 of the height of the peripheral wall portion 12g.

The second weir portion 12j is bent so that the center in the width direction projects toward the short side 12b on the ridge side, and both ends close to the peripheral wall portion 12g are free ends. The height of the second weir portion 12j is the same as the height of the cylindrical weir portion 12e. That is, the second weir portion 12j is formed higher than the lower portion in the first weir portion 12i.

Further, the main body member 12 has a plurality of mounting holes 12k penetrating the substrate portion 12a. The mounting holes 12k are provided at four locations, one on the outside of the peripheral wall portion 12g and near both ends of the ridge side short side 12b, and the other on the ridge side short side 12b side of the pair of first weir portions 12i. .. A mounting screw 18 described later for mounting the main body member 12 on the roof material 2 is inserted into the mounting hole 12k. The peripheral edge of the mounting hole 12k is formed higher than the upper surface of the substrate portion 12a.

Further, the main body member 12 has a groove portion 12l between the screw hole 12h close to the opening 12d in the peripheral wall portion 12g and the inner peripheral surface of the peripheral wall portion 12g.

The lid member 13 is mounted by closing the inside of the frame of the flat and frame-shaped mounting portion 13a, the lid peripheral wall portion 13b extending downward from the outer peripheral edge of the mounting portion 13a, and the mounting portion 13a. It has a top wall portion 13c that bulges upward from the placement portion 13a. Further, the lid member 13 has a plurality of assembly holes 13d penetrating the mounting portion 13a, and a pair of protruding wall portions 13e extending downward from the lower surface of the top wall portion 13c ( See FIG. 6).

The outer shape of the mounting portion 13a is substantially similar to the outer shape of the peripheral wall portion 12g of the main body member 12. The lid peripheral wall portion 13b extends downward with a length of ½ of the height of the peripheral wall portion 12g of the main body member 12.

In a plan view, the top wall portion 13c is a top wall central portion 13ca located in the central portion of the frame of the mounting portion 13a and a heaven extending from the top wall central portion 13ca to the eaves side short side 12c side. It has a wall rear portion 13 cc, and a top wall peripheral edge portion 13 cc that connects the widthwise edge of the top wall central portion 13 ca and the top wall rear portion 13 cc and the inner peripheral edge of the mounting portion 13a.

The central portion 13ca of the top wall is located above the mounting portion 13a and is inclined so as to be lower from the short side 12b on the ridge side toward the short side 12c on the eaves side (see FIG. 4). .. In the top wall central portion 13ca, the edge near the ridge side short side 12b is located above the center of the opening 12d of the main body member 12 in a state where the wire rod retractor 10 is assembled, and the eaves side short side. The edge close to 12c is located on the eave side short side 12c side of the first weir portion 12i.

The top wall rear portion 13cc is a mounting portion from the edge of the top wall central portion 13ca near the eaves side short side 12c to the same position in the longitudinal direction as the edge of the mounting portion 13a near the eaves side short side 12c. It extends parallel to 13a. The central portion 13ca of the top wall and the rear portion 13cc of the top wall are flat. On the other hand, the top wall peripheral portion 13cc is a curved surface, and is continuously connected to the top wall central portion 13ca and the top wall rear portion 13cc.

The assembly hole 13d is formed at a portion corresponding to the three screw holes 12h of the main body member 12. The pair of projecting wall portions 13e extend downward from the same positions as the top wall central portion 13ca and the top wall rear portion 13cc on the lower surface of the top wall peripheral portion 13cc in the longitudinal direction. The lower surface of the protruding wall portion 13e is on the same surface as the lower surface of the mounting portion 13a.

The details of the first waterproof material 14 will be described later, but at the construction site where the wire rod retracting tool 10 is attached, the sheet-shaped member is rolled into a cylindrical shape, and a plurality of cuts are made in the upper end portion to the outside. It is bent. The first waterproof material 14 is shipped in a sheet-like state with release papers stuck on both sides. The second waterproof material 15 has a sheet shape that is one size smaller than the outer shape of the substrate portion 12a of the main body member 12, and a hole 15a having an inner diameter larger than that of the opening 12d is formed in a portion corresponding to the opening 12d. The second waterproof material 15 is attached to the lower surface of the main body member 12 in advance at the time of shipment of the product. The first waterproof material 14 and the second waterproof material 15 are formed of a butyl rubber sheet.

The third waterproof material 16 is a putty made of a synthetic resin having water resistance, waterproofness, and insulating properties such as Plaseal (registered trademark). A predetermined amount of the third waterproof material 16 is included at the time of shipment of the product. The fourth waterproof material 17 is foam rubber. At the time of shipment of the product, the fourth waterproof material 17 is previously provided on the lower surface of the top wall portion 13c of the lid member 13 at a portion on the eave side short side 12c side of the pair of protruding wall portions 13e over the entire length in the width direction. It is pasted.

The guide member 11 of the wire lead-in tool 10 is formed by either injection molding of a synthetic resin or casting of an aluminum alloy. Further, the main body member 12 and the lid member 13 are formed by casting an aluminum alloy.

Subsequently, the construction of a wire rod pulling structure for pulling the wire rod 3 into the building from above the roof material 2 using the wire rod pulling tool 10 will be described. In this embodiment, a case where the roof structure 1 is a field board and the roof material 2 is a slate is illustrated.

First, a through hole 4 having an inner diameter slightly larger than the diameter of the guide portion 11a of the guide member 11 is formed from above so as to penetrate the roof material 2 and the roof structure 1 at a portion of the roof material 2 to which the wire rod retracting tool 10 is attached. Form. Next, the release paper on one side of the sheet-shaped first waterproof material 14 is peeled off, and in a state where the upper end is projected to some extent from the upper surface of the roofing material 2, the side from which the release paper is peeled off is on the outside, and the through hole 4 is formed. Wrap it while sticking it on the inner peripheral surface. Then, after cutting off the overlapping portion in the circumferential direction of the through hole 4, a plurality of cuts are made in the portion protruding from the upper surface of the roofing material 2 and bent outward, and the upper surface of the roofing material 2 is also formed. paste.

After that, after peeling off the release paper on the remaining surface of the first waterproof material 14, the guide member 11 with the collar portion 11b facing upward is guided to the tubular portion of the first waterproof material 14. The part 11a is inserted. At this time, the guide member 11 is press-fitted so that the lower surface of the flange portion 11b of the guide member 11 in the first waterproof material 14 comes into contact with the portion of the first waterproof material 14 that is attached to the roof material 2. .. As a result, the space between the guide member 11 and the through hole 4 is sealed by the first waterproof material 14, and rainwater can be prevented from entering the building.

Next, the main body member 12 in which the second waterproof material 15 is attached to the lower surface of the substrate portion 12a is placed in the opening 12d with the short side 12b on the ridge side facing the ridge side. It is placed on the roofing material 2 so that the portion 11b is inserted. Then, the mounting screw 18 passed through the mounting hole 12k from above is screwed into the roof structure 1 to mount the main body member 12 on the roof material 2.

At this time, if the guide member 11 is not sufficiently inserted into the through hole 4 and the flange portion 11b protrudes upward from the roof material 2, the protrusion 12f of the main body member 12 hits the collar portion 11b from above. The main body member 12 moves downward due to the contact and tightening of the mounting screw 18, so that the protrusion 12f presses the guide member 11 downward. As a result, the guide member 11 is sufficiently inserted into the through hole 4.

After the main body member 12 is attached to the roof material 2, the wire rod 3 is inserted into the opening 12d and the guide portion 11a from above and pulled into the building, and is bent toward the eaves above the opening 12d to form the peripheral wall portion 12g. It extends from the open eaves side short side 12c side to the eaves side. At this time, the wire rod 3 is passed above the low portion of the first dam portion 12i. Further, when a plurality of wire rods 3 are pulled into the building, they are arranged in the width direction on the eaves side of the opening 12d.

Then, the clay-like third waterproofing material 16 is filled inside the opening 12d and the guide 11a from above so as to fill the space between the opening 12d and the guide member 11 and the wire 3, and water is stopped (FIG. See 2). After that, the lid member 13 is covered from above the main body member 12, and the mounting screw 19 passed through the assembly hole 13d is screwed into the screw hole 12h and tightened. At this time, the fourth waterproof material 17 of foam rubber attached to the lower surface of the lid member 13 is elastically deformed, and water is stopped between the lid member 13 and the wire rod 3 (see FIG. 1 (b)). .. As a result, the wire rod retracting tool 10 is mounted on the roof material 2, and a wire rod retracting structure is constructed in which the wire rod 3 is drawn into the building from above the roofing material 2 via the wire rod retracting tool 10 ( See FIG. 1 (a)).

Here, since the top wall central portion 13ca of the top wall portion 13c of the lid member 13 is inclined so as to be lowered from the ridge side toward the eaves side, FIG. 2 shows the state in which the wire rod lead-in structure is constructed. As shown, the central portion 13ca of the top wall is inclined so as to approach the substrate portion 12a toward the eaves side. That is, when the wire rod retracting tool 10 is attached to the roof material 2, the central portion 13ca of the top wall is inclined so as to be lower toward the eaves side with respect to the upper surface of the roof material 2. Since the raised ridge-side edge of the top wall 13ca is located above the opening 12d, if dew condensation occurs inside the lid member 13, the water will be discharged from the opening 12d. It is possible to facilitate the flow in the direction, and it is possible to prevent the condensed water from falling into the opening 12d.

The water that condenses on the inside of the lid member 13 and falls toward the eaves side from the opening 12d flows down on the substrate portion 12a of the main body member 12 toward the eaves side, and the pair of first weir portions 12i and the second weir portion After being guided to 12j, it is discharged onto the external roofing material 2 from the eaves-side edge of the substrate portion 12a.

On the other hand, the intrusion of rainwater through the wire rod 3 into the wire rod drawing tool 10 is blocked by the fourth waterproof material 17 that closes between the wire rod 3 and the lid member 13. Further, the infiltration of rainwater into the inside of the wire rod drawing tool 10 below the wire rod 3 is blocked by the second weir portion 12j near the eaves side edge of the main body member 12. Even if rainwater invades between the second weir portion 12j and the peripheral wall portion 12g, it is blocked by a pair of first weir portions 12i on the ridge side, and further dammed by the cylindrical weir portion 12e on the ridge side. Can be stopped. Even if rainwater invades the inside of the wire drawing tool 10, it is guided to the eaves side by the pair of the first weir portion 12i and the second weir portion 12j and discharged to the outside in the same manner as the water condensed inside. As described above, the cylindrical weir portion 12e, the first weir portion 12i, and the second weir portion 12j have a configuration in which rainwater is less likely to enter and is easily discharged to the outside, so that it is difficult for rainwater to reach the opening 12d. The ingress of rainwater and dew condensation water into the building through the opening 12d and the guide member 11 is effectively prevented.

As described above, according to the present embodiment, since the opening 12d of the main body member 12 has the protrusion 12f extending upward from the flange portion 11b of the guide member 11, the guide to the through hole 4 is provided. Even if the flange portion 11b protrudes upward from the roof material 2 due to insufficient insertion of the portion 11a, the protrusion 12f comes into contact with the collar portion 11b from above when the main body member 12 is mounted on the roof material 2. The guide member 11 can be pressed downward. As a result, the guide portion 11a can be sufficiently inserted into the through hole 4, and rainwater can be prevented from entering the building through the guide member 11 and the through hole 4.

Further, according to the present embodiment, since the guide member 11 is a separate member located below the main body member 12, it is inserted into the through hole 4 of the roof material 2 and the roof structure 1 and placed on the roof material 2. The main body member 12 may be placed on the roof material 2 so that the opening 12d is fitted to the flange portion 11b of the protruding guide member 11, and the main body member 12 can be easily attached. can do. Further, since the guide member 11 is a separate member from the main body member 12, the main body member 12 can be mounted on the roof material 2 even if the through hole 4 is tilted from the direction perpendicular to the upper surface of the roof material 2. It is not necessary to carefully perform the drilling work as in.

Further, according to the present embodiment, since the central portion 13ca of the top wall of the lid member 13 is inclined so as to be lower toward the eaves side with respect to the upper surface of the roof material 2, the wire rod retracting structure of the present embodiment Even when the roof is constructed on a gently sloping roof, the water that has condensed inside the lid member 13 of the wire drawing tool 10 is more likely to flow toward the eaves than the opening 12d, and the condensed water falls toward the opening 12d. It can be prevented from doing so.

Further, according to the present embodiment, the protruding portion 12f protruding in the opening 12d of the main body member 12 is projected from the ridge side to the eaves side. In other words, since the protrusion 12f of the main body member 12 does not protrude from the eaves side to the ridge side in the opening 12d, there are the following advantages. More specifically, assuming that the protrusion is projected from the eaves side to the ridge side in the opening 12d, when the wire 3 inserted through the opening 12d and the guide member 11 is bent toward the eaves, the wire 3 The protrusion is located inside the bend. In that case, if the curvature of the wire rod 3 is small, it is easy to hit the protrusion, so it is necessary to increase the curvature of the wire rod 3, and the large curvature makes it easy for the wire rod 3 to break. On the other hand, in the present embodiment, since the protrusion 12f is not projected from the eaves side to the ridge side, it is possible to suppress an increase in the curvature of the wire rod 3 and suppress disconnection of the wire rod 3. Can be done.

Further, according to the present embodiment, since the inner diameter of the opening 12d of the main body member 12 is larger than the outer diameter of the flange portion 11b of the guide member 11, when the main body member 12 is mounted on the roof material 2, the wire rod 3 The inner diameter of the part through which is inserted becomes larger toward the top. As a result, when the wire rod 3 inserted through the opening 12d and the guide member 11 is bent toward the eaves, its curvature can be reduced, and the same effect as described above can be obtained.

Further, according to the present embodiment, a low portion is formed in the pair of first weir portions 12i close to the opening 12d so that the wire rod 3 is passed above the portion, so that the entire wire rod retracting tool 10 is formed. It is possible to lower the height. As described above, when the wire rod retracting tool 10 has a low height, for example, when the solar cell module is installed above the wire rod retracting tool 10, the height of the solar cell module from the roof material 2 can be lowered. There is.

Although the present invention has been described above with reference to preferred embodiments, the present invention is not limited to the above embodiments, and various improvements and design changes can be made without departing from the gist of the present invention. Is. In the following, parts having the same configuration are designated by the same reference numerals, and detailed description thereof will be omitted.

For example, in the above embodiment, the main body member 12 has one protrusion 12f, but the present invention is not limited to this, and as shown in FIG. 7A, two protrusions 12f are provided. It may have three protrusions 12f as shown in FIG. 7B. More specifically, in FIG. 7A, the protrusions 12f are projected from both sides in the width direction on the inner peripheral surface of the opening 12d. Further, in FIG. 7B, the protrusions 12f are projected from the ridge side on the inner peripheral surface of the opening 12d and both sides in the width direction, respectively. In this way, even if a plurality of protrusions 12f are provided, the same effect as described above can be obtained. The only difference between the main body member 12 of FIG. 7 and the main body member 12 of the above-described embodiment is the number and position of the protrusions 12f, and the same components are designated by the same reference numerals and description thereof will be omitted.

Further, in the above embodiment, the protrusion 12f of the main body member 12 is projected at the upper end edge of the opening 12d, but the present invention is not limited to this, and the protrusion 12f is projected in the middle of the opening 12d in the vertical direction. The portion 12f may be projected.

Further, in the above embodiment, the roofing material 2 is used as a slate, but the present invention is not limited to this, and a sheet metal roofing material, an asphalt single, or a roof tile may be used.
