Description

The present invention relates to a drainage member.

For example, the retaining material and connecting material described in Patent Document 1 are used to hide the seams between exterior panels that serve as roofing materials. The retaining material is made of a metal plate, and is formed with a plate receiving portion, an engaging recess, a bottom mounting portion, and a rising portion that are curved, while the connecting material is made of a metal plate, and is composed of a pair of horizontal portions made of a single plate of approximately the same width that face each other on the same plane, and a mating protrusion that extends perpendicular to the horizontal portions below the opposing portions of the horizontal portions, and the mating protrusion can be pressed into the mating recess.

The retaining material and the bonding material are applied in a state where a groove of a specified width is formed in the base material arranged on the top of the building, a waterproof sheet is fitted into the groove, and then a U-shaped recessed portion of the water receiving material that can be freely fitted into the groove is fitted and placed on top of the waterproof sheet. Specifically, the retaining material is placed in the recessed portion, and after the above-mentioned bottom surface portion is fixed to the bottom of the recessed portion, the side edge of the outer enclosure plate that is arranged parallel to the base material is placed so as to be supported on the plate receiving portion, and the fitting convex portion is fitted into the engagement concave portion so that the horizontal portion presses against the upper surface of the side of the outer enclosure plate. Thus, the seam between the adjacent outer enclosure plates is sealed by the horizontal portion, and water intrusion from this portion is prevented.

Japanese Patent Application Laid-Open No. 9-209512

Incidentally, the mounting bottom surface portion may be fixed to the bottom of the recessed portion, for example, using an adhesive. However, in the configuration described in Patent Document 1, the bonding position of the mounting bottom surface portion relative to the bottom of the recessed portion was not clear. Therefore, for example, depending on the bonding position of the mounting bottom surface portion relative to the bottom of the recessed portion, the engaging recess may be hidden by the outer surrounding plate, and as a result, the fitting protrusion cannot be fitted into the engaging recess.

Therefore, the present invention aims to provide a drainage member that allows the positioning of roofing material protection equipment.

The present invention is applied to a roof structure comprising a roof underlayment, a roofing material covering the roof underlayment, and a roofing material protector having a side end covering portion covering the side end of the roofing material, and is a plate-shaped water drainage member arranged between the roof underlayment and the roofing material, and is provided with a base portion placed on the roof underlayment and a blocking wall portion rising from the base portion, and a blocking protrusion portion is formed on the blocking wall portion that protrudes in the girder direction, and the blocking protrusion portion positions the roofing material protector in the vertical direction by engaging with the water drainage member.

According to the above configuration, the blocking protrusion protruding from the blocking wall portion in the girder direction engages with the roofing material protector to position the roofing material protector in the up-down direction, making it possible to clearly indicate the position of the roofing material protector relative to the water drainage member.

In addition, in the present invention, the roofing material protector may include a blocking wall fixing portion that abuts against the blocking wall surface of the blocking wall portion, and the blocking wall fixing portion may have a through hole that penetrates in the girder direction, and the blocking protrusion may be inserted into the through hole.

According to this configuration, the blocking protrusion is inserted into the through hole, so that the roofing material protector can be engaged with the drainage member, and the roofing material protector can be positioned in the vertical direction.

The present invention is also applicable to a roof structure comprising a roof underlayment, a roofing material covering the roof underlayment, and a roofing material protector having a side end covering portion covering the side end of the roofing material, and is a plate-shaped water drainage member arranged between the roof underlayment and the roofing material, and is provided with a base portion placed on the roof underlayment, a blocking wall portion extending in the vertical direction, and a blocking placement portion connected to the blocking wall portion and placed on the base portion, and a blocking protrusion portion is formed on the blocking placement portion that protrudes in the vertical direction, and the blocking protrusion portion positions the roofing material protector in the girder direction by engaging with the water drainage member.

According to the above configuration, the blocking protrusion protruding in the vertical direction from the blocking placement portion engages with the roofing material protector to position the roofing material protector in the girder direction, thereby making it possible to clearly indicate the position of the roofing material protector relative to the water drainage member.

In addition, in the present invention, the roofing material protector includes a drain placement part that is placed on the drain connection surface of the drain placement part, and a through hole that penetrates in the vertical direction is formed in the drain placement part, and the drain protrusion may be inserted into the through hole.

According to the above configuration, the blocking protrusion is inserted into the through hole, so that the roofing material protector can be engaged with the water drainage member, and the roofing material protector can be positioned in the girder direction.

In addition, in the present invention, the roofing material may be made of a softer material than the hard materials such as slate and metal.

According to the above configuration, since the roof material is made of a softer material than hard materials such as slate or metal, the blocking protrusion can effectively prevent the roof material from being lifted up by strong winds, for example.

In addition, in the present invention, the roof structure may include a solar cell module placed on the roof substrate, and the blocking wall portion may be disposed between the roof material and the solar cell module.

As described above, the drainage member of the present invention allows the position of the roofing material protector relative to the drainage member to be clearly defined, making it possible to position the roofing material protector.

FIG. 1 is a plan view of a roof structure according to a first embodiment of the present invention. FIG. 2 is a cross-sectional view of the roof structure in the embodiment as viewed from the spanning direction. FIG. 3 is a cross-sectional view of a roof structure according to the second embodiment as viewed from the spanning direction. FIG. 4 is a cross-sectional view of a roof structure according to the third embodiment as viewed from the spanning direction.

The following describes the roof structure 2 according to the first embodiment of the present invention.

In the following description, the direction in which the eaves beams and ridge beams (not shown) of the building extend is defined as the "beam direction Y", the direction spanning two imaginary lines extending in the beam direction Y is defined as the "spanning direction X", and the up-down direction in Figures 2 to 4 is defined as the "vertical direction Z". The span direction X intersects with the beam direction Y and the vertical direction Z, and in this embodiment, the beam direction Y and the vertical direction Z are perpendicular to each other.

In addition to the aforementioned directions X, Y, and Z in the building, when describing the configuration of the roof underlayment 3, solar cell module 4, water drainage member 5, roofing material 6, and roofing material protector 1, the direction indicating the length of each is defined as the "length direction x," the direction indicating the width of each is defined as the "width direction y," and the direction indicating the height of each is defined as the "height direction z." Note that the length direction x, width direction y, and height direction z are perpendicular to each other.

The roof structure 2 will now be described. In this embodiment, the roof structure 2 will be described as being inclined downwards as it moves from the ridge side to the eaves side. Therefore, the spanning direction X will be the eaves-ridge direction Xa along which the rafters extend. In addition, for the roof structure 2 that slopes downwards as it moves from the ridge side to the eaves side, it is preferable for the slope angle to be 14 degrees (2.5 inch slope) or more.

As shown in FIG. 2, the roof structure 2 includes a roof underlayment 3, a solar cell module 4, a water drainage member 5, a roof material 6, and a roof material protector 1.

The roof underlayment 3 extends in the width direction y and the length direction x. In this embodiment, the roof underlayment 3 is arranged so that the width direction y is aligned with the girder direction Y and the length direction x is aligned with the eaves-ridge direction Xa. As shown in FIG. 2, the roof underlayment 3 in this embodiment comprises a flat sheathing board 30 and a roofing sheet 31 placed on the sheathing board 30. The roofing sheet 31 is waterproof. This prevents water from being transmitted to the sheathing board 30 through the roofing sheet 31, preventing, for example, water from leaking indoors.

The solar cell module 4 is an integrated building material that functions as both a roofing material (e.g., a roof tile) and a solar cell. As shown in FIG. 2, the solar cell module 4 includes a solar cell panel 40 and a panel mounting portion 41.

The solar cell panel 40 is a plate-shaped panel having a light receiving surface 400 on its surface, and converts the light energy received by the light receiving surface 400 into electrical energy in solar cells provided inside. As shown in FIG. 1, the solar cell panel 40 is configured as a rectangular plate extending in the width direction y and the length direction x. In this embodiment, multiple solar cell panels 40 are arranged.

The panel mounting portion 41 is for mounting the solar panel 40 to the roof underlayment 3. As shown in FIG. 3, the panel mounting portion 41 includes a panel support portion (not shown or numbered) and a mounting body portion 411.

The panel support is primarily intended to support the solar panel 40 from below. In this embodiment, the panel support is located on the inside (right side in FIG. 2) of the solar panel 40 in the width direction y.

The mounting body 411 is used when mounting the solar cell module 4 to the roof underlayment 3. The mounting body 411 is configured in a plate shape (for example, a metal plate shape). The mounting body 411 is disposed below the panel support. The mounting body 411 of this embodiment is longer than the panel support in the width direction y. Therefore, as shown in FIG. 2, the mounting body 411 faces the underside (not numbered) of the solar cell panel 40 in the height direction z. Also, as shown in FIG. 2, the mounting body 411 of this embodiment extends outward in the width direction y beyond the solar cell panel 40. Furthermore, the mounting body 411 of this embodiment has a folded portion 412 by folding back the outer end in the width direction y.

As described above, the panel support portion of this embodiment is disposed inwardly of the solar cell panel 40 in the width direction y. The mounting body portion 411 of this embodiment is longer than the panel support portion in the width direction y and faces the underside of the solar cell panel 40. Therefore, in the solar cell module 4 of this embodiment, a gap space 413 is formed that is defined by the underside of the solar cell panel 40, the end face (not numbered) of the panel support portion in the width direction y, and the mounting body portion 411.

The drainage member 5 is for directing water on the roof so that it can be drained. In this embodiment, the drainage member 5 comprises a drainage main body 50 and a blocking portion 5a provided on the drainage main body 50.

The drain body 50 is placed on the roof underlayment 3 (it may be placed directly or indirectly). The drain body 50 is made of a plate-shaped member (specifically, a metal plate). This drain body 50 is plate-shaped and extends in the width direction y and the length direction x. In this embodiment, the drain body 50 is shorter in the width direction y than the mounting body 411. In addition, the drain body 50 in this embodiment includes a substantially flat base portion 500 and a folded portion 505 formed at the end in the width direction y.

The base portion 500 extends in the width direction y and the length direction x. In this embodiment, the length of the base portion 500 in the length direction x is longer than the length of the width direction y. The base portion 500 has a protrusion 501 that protrudes upward. In this embodiment, the protrusion 501 is formed by bending the base portion 500 in the width direction y. Therefore, the protrusion 501 in this embodiment is formed over the entire area of the length direction x of the base portion 500. In this embodiment, multiple (specifically, eight) protrusions 501 are formed in the width direction y. Note that in FIG. 2, four protrusions 501 are illustrated, and four protrusions 501 are omitted.

2, in the base portion 500 of this embodiment, a base region 502 is formed between two adjacent protrusions 501 (the protrusion 501 on the right side as the other side in the width direction y is not shown) at approximately the center in the width direction y, which is used when attaching the blocking portion 5a described later. In addition, in the base portion 500, a drainage region 503 is formed between the two adjacent protrusions 501 in the width direction y and between the protrusions 501 and the folded portion 505 described later, which is used to guide water in the length direction x. Here, the protrusions 501 of this embodiment are formed over the entire length direction x of the base portion 500. Therefore, the drainage region 503 of this embodiment guides water over the entire length direction x. Furthermore, in the base portion 500, an adhesive region 504 is formed between the two adjacent protrusions 501 and adjacent to the drainage region 503 in the width direction y, which is used to apply an adhesive. In this embodiment, the base region 502 is longer than the drainage region 503 and the adhesive region 504 in the width direction y. Also, in this embodiment, the drainage region 503 is longer than the adhesive region 504 in the width direction y.

The folded-back portion 505 is formed by folding back the end of the plate-shaped drainer body 50 in the width direction y upward. In this embodiment, the folded-back portion 505 is disposed on both ends of the base portion 500 in the width direction y.

The blocking portion 5a is for blocking the space above the drain member 5 in the width direction y. As shown in FIG. 2, the blocking portion 5a in this embodiment is formed by bending a plate-shaped member (specifically, a metal plate) extending in the width direction y and the length direction x, and has a substantially T-shaped cross section. The blocking portion 5a in this embodiment is shorter than the drain main body portion 50 in the width direction y and the length direction x. The blocking portion 5a includes a blocking wall portion 5b and a blocking placement portion 5d.

As shown in FIG. 2, the blocking wall portion 5b extends in the height direction z. In this embodiment, the blocking wall portion 5b is configured in a plate shape (specifically, a rectangular plate shape) that extends in the height direction z and the length direction x. Therefore, as shown in FIG. 2, the blocking wall portion 5b has a blocking wall surface 5c on one side in the width direction y. In this embodiment, the length of the blocking wall portion 5b in the height direction z is longer than the length of the gap space 413 in the height direction z.

The blocking wall surface 5c is formed with a blocking protrusion 5c1 that protrudes in the width direction y. This blocking protrusion 5c1 is configured in a rod shape extending in the width direction y. Note that the blocking protrusion 5c1 may be configured in a plate shape extending in the width direction y and the length direction x. As shown in FIG. 2, the blocking wall surface 5c of this embodiment is formed with a blocking protrusion 5c1 that protrudes to one side in the width direction y. Although not shown, in this embodiment, multiple blocking protrusions 5c1 are arranged at a distance in the length direction x. Furthermore, as shown in FIG. 2, the blocking protrusion 5c1 of this embodiment is arranged at a distance from the blocking placement portion 5d described later in the height direction z.

The interrupter placement portion 5d is used when connecting the interrupter portion 5a to the drain body portion 50. This interrupter placement portion 5d extends in the width direction y and the length direction x. Also, as shown in FIG. 2, the interrupter placement portion 5d is connected to one end (lower end) of the interrupter wall portion 5b in the height direction z. Therefore, the interrupter placement portion 5d of this embodiment is arranged so as to be perpendicular to the interrupter wall portion 5b. The interrupter placement portion 5d of this embodiment is provided on one side and the other side of the interrupter wall portion 5b in the width direction y. Also, in this embodiment, the interrupter placement portion 5d arranged on one side of the width direction y has an interrupter connection surface 5e extending in the width direction y and the length direction x at the other end (upper end) of the height direction z. The interrupter placement portion 5d of this embodiment is shorter than the base region 502 in the width direction y. Therefore, the interrupter portion 5a of this embodiment is shorter than the base region 502 in the width direction y and is configured to be placed on the base region 502. Furthermore, the interrupter placement portion 5d of this embodiment is configured to be fixed to the base region 502. Possible fixing methods include, for example, adhesive fixing or fixing using a fastener (not shown).

The draining member 5 is constructed by placing the draining placement portion 5d on the base region 502 of the base portion 500 with the width direction y of the blocking portion 5a aligned with the width direction y of the draining body portion 50, and fixing the blocking placement portion 5d to the base region 502. Therefore, as shown in FIG. 2, the blocking wall portion 5b rises from the base portion 500. In addition, in this embodiment, by placing the blocking portion 5a on the draining body portion 50, the draining member 5 is divided into one draining portion 5A on one side of the width direction y and the other draining portion 5B on the other side of the width direction y, with the blocking wall portion 5b as the boundary in the width direction y. In this embodiment, the one draining portion 5A is shorter than the other draining portion 5B in the width direction y to prevent the base portion 500 from being placed on the folded portion 412 and causing problems.

Next, we will explain the roofing material protector 1.

The roofing material protector 1 is used, for example, to protect the roofing material 6 described below from rainwater. The roofing material protector 1 of this embodiment is constructed by bending a plate-shaped member (specifically, a metal plate) that extends in the width direction y and the length direction x. Specifically, as shown in FIG. 2, the roofing material protector 1 of this embodiment is constructed by bending a plate-shaped member into a substantially U-shape. The roofing material protector 1 includes a protective main body portion 1a and a drain fixing portion 11.

The protective body 1a has a side end covering portion 1b and a folded portion 1c formed on one side of the side end covering portion 1b in the width direction y.

The side end covering portion 1b is intended to cover from above the side end 60 of the roofing material 6 described later. As shown in FIG. 2, the side end covering portion 1b extends in the length direction x and the width direction y. In this embodiment, the side end covering portion 1b is rectangular in shape with the length in the length direction x being longer than the length in the width direction y. Also, as shown in FIG. 2, the length in the width direction y of the side end covering portion 1b in this embodiment is shorter than the length in the width direction y of the roofing material 6 described later.

As shown in FIG. 2, the folded portion 1c is formed by folding one end of the protective body 1a in the width direction y downward. Therefore, the folded portion 1c can be hidden below the side end cover portion 1b, which prevents one end of the protective body 1a in the width direction y from being exposed to rain, thereby preventing the protective body 1a from rusting. Furthermore, for example, water droplets flowing downward from the protective body 1a along the folded portion 1c can be prevented from rusting. In addition, by folding one end of the protective body 1a in the width direction y downward, one end of the side end cover portion 1b in the width direction y can be rounded, which can prevent, for example, injuries to the worker's hands.

The drain fixing part 11 is used to adhesively fix the roofing material protector 1 to the drain member 5. In this embodiment, the drain fixing part 11 includes a blocking wall fixing part 12 and a drain placement part 13.

The barrier fixing portion 12 is used to adhesively fix the roofing material protector 1 to the barrier wall portion 5b. As shown in FIG. 2, the barrier fixing portion 12 extends in the height direction z. The barrier fixing portion 12 of this embodiment is rectangular in shape with the length in the length direction x being longer than the length in the height direction z. Therefore, the barrier fixing portion 12 of this embodiment has a barrier fixing surface 12a extending in the height direction z and the length direction x on the other side in the width direction y. As shown in FIG. 2, the barrier fixing portion 12 of this embodiment is disposed lower than the side end covering portion 1b in the height direction z. Specifically, the barrier fixing portion 12 of this embodiment is continuous with the other end of the side end covering portion 1b in the width direction y. The barrier fixing portion 12 of this embodiment is longer than the thickness of the roofing material 6 in the height direction z. Furthermore, the barrier fixing portion 12 of this embodiment is shorter than the barrier wall portion 5b in the height direction z. The length of the barrier wall fixing portion 12 in the height direction z of this embodiment is configured to be shorter than the distance in the height direction z between the barrier mounting portion 5d and the barrier protrusion 5c1. Therefore, as shown in FIG. 2, the barrier wall fixing portion 12 in this embodiment can be disposed between the barrier mounting portion 5d and the barrier protrusion 5c1. Note that the length of the barrier wall fixing portion 12 in the height direction z may be approximately the same as the distance in the height direction z between the barrier mounting portion 5d and the barrier protrusion 5c1.

The drain placement portion 13 is placed on the drain member 5 (specifically, the barrier placement portion 5d). In addition, the drain placement portion 13 of this embodiment is adhesively fixed to the drain member 5. The drain placement portion 13 extends in the width direction y. In this embodiment, the drain placement portion 13 is rectangular in shape with the length in the length direction x being longer than the length in the width direction y. In addition, as shown in FIG. 2, the drain placement portion 13 of this embodiment is longer in the width direction y than the side end cover portion 1b and the barrier placement portion 5d. Furthermore, the drain placement portion 13 of this embodiment is continuous with one end (lower end) of the barrier wall fixing portion 12 in the height direction z. Therefore, the drain placement portion 13 is disposed on one side of the barrier wall fixing portion 12 in the width direction y. Therefore, the drain placement portion 13 is disposed opposite the side end cover portion 1b in the height direction z.

Here, in this embodiment, the blocking wall fixing part 12 is continuous with the other end of the side end covering part 1b in the width direction y, and the drain placement part 13 is continuous with one end (lower end) of the blocking wall fixing part 12 in the height direction z. Therefore, as shown in FIG. 2, in this embodiment, the side end covering part 1b, the blocking wall fixing part 12 as the drain fixing part 11, and the drain placement part 13 are integrally configured.

The roofing material 6 covers the roof underlayment 3 and prevents rainwater from penetrating into the roof underlayment 3. The roofing material 6 in this embodiment is made of a softer material than hard materials such as slate and metal. Specifically, asphalt shingles are used as the roofing material 6 in this embodiment. Therefore, the roofing material 6 in this embodiment is easy to cut, and for example, a worker can cut the roofing material 6 to fit the shape of the roof. The roofing material 6 is shorter than the barrier wall fixing part 12 in the height direction z. In this embodiment, the thickness of the multiple roofing materials 6 is shorter than the length of the barrier wall fixing part 12 in the height direction z. Therefore, the roofing material 6 (specifically, the side end 60) can be arranged between the side end covering part 1b and the water drain placement part 13, which are arranged opposite each other in the height direction z. As shown in FIG. 1, in this embodiment, multiple roofing materials 6 are arranged in a checkerboard pattern to cover the roof underlayment 3.

In the above roof structure 2, first, as shown in Figure 2, a waterproof roofing sheet 31 is placed on the sheathing board 30 to form the roof foundation 3. Next, the mounting body 411 is placed on the roofing sheet 31 with the width direction y of the solar cell module 4 aligned with the girder direction Y, the length direction x aligned with the ridge direction Xa, and the height direction z aligned with the up-down direction Z so that the solar cell panel 40 is positioned above the panel mounting part 41. This allows the solar cell module 4 to be placed on the roof foundation 3.

Next, the drainage member 5 is placed on the mounting body 411 with the width direction y of the drainage member 5 aligned with the girder direction Y, the length direction x aligned with the eaves-ridge direction Xa, and the height direction z aligned with the up-down direction Z so that the blocking portion 5a is located on the upper side of the drainage body 50. Here, the drainage body 50 of this embodiment is shorter than the mounting body 411 in the width direction y. Therefore, as shown in FIG. 2, the drainage body 50 can be placed on the mounting body 411. Specifically, the drainage member 5 is placed on the mounting body 411 on one side in the width direction y so that the other drainage portion 5B is placed in the gap space 413. Here, the length of the height direction z of the blocking wall portion 5b of this embodiment is longer than the length of the height direction z of the gap space 413. Therefore, by placing the drainage member 5 on the mounting body 411, the blocking wall portion 5b is placed opposite the solar panel 40 in the width direction y. Therefore, the blocking wall portion 5b blocks the gap space 413 from one side in the width direction y. In particular, the blocking wall portion 5b of this embodiment is a plate-like shape that extends in the height direction z and the length direction x, so it can block the gap space 413 in the girder direction Y. Therefore, the blocking portion 5a can prevent rainwater, birds, and insects from entering the gap space 413 from one side in the width direction y. Thus, in this embodiment, the water drainage member 5 is placed on the roof foundation 3 via the mounting body portion 411.

Then, as shown in FIG. 3, the fastener screw is inserted through the drainage area 503 of the base portion 500, the mounting body portion 411, and the roof underlayment 3 to fix the water drainage member 5 and the solar cell module 4 to the roof underlayment 3. Then, the roof underlayment 3 is covered with the roof material 6 so that the roof material 6 is arranged on the one water drainage portion 5A side of the water drainage member 5. At this time, at least the side end 60 of the roof material 6 is arranged opposite the one water drainage portion 5A of the water drainage member 5 in the vertical direction Z. Also, as shown in FIG. 1, in this embodiment, in the eaves-ridge direction Xa, multiple roof materials 6 are arranged on the roof underlayment 3 so that at least a part of the roof material 6 on the ridge side (upper side in FIG. 1) overlaps with the roof material 6 on the eaves side (lower side in FIG. 1). In this way, the roof structure 2 is constructed.

Next, the roofing material protector 1 is installed on the drainage member 5. As shown in FIG. 2, the roofing material protector 1 of this embodiment is installed on one drainage section 5A of the drainage member 5. Specifically, the roofing material protector 1 is installed on one drainage section 5A with the width direction y of the roofing material protector 1 aligned with the girder direction Y, the length direction x aligned with the eaves-ridge direction Xa, and the height direction z aligned with the up-down direction Z so that the protective main body section 1a is positioned above the drainage fixing section 11.

As shown in FIG. 2, before the roofing material protector 1 is installed, adhesive is applied to the blocking connection surface 5e and blocking wall surface 5c of the water drainage member 5.

As shown in FIG. 2, in this embodiment, the blocking wall fixing portion 12 is disposed between the blocking protrusion 5c1 and the blocking placement portion 5d, the blocking fixing surface 12a is adhesively fixed to the blocking wall surface 5c, and the water drain placement portion 13 is placed on the blocking placement portion 5d and adhesively fixed. At this time, as shown in FIG. 2, the side end cover portion 1b and the blocking protrusion 5c1 abut in the vertical direction. Therefore, the roofing material protector 1 is engaged with the water drain member 5. In this way, the roofing material protector 1 is installed on one of the water drainage portions 5A.

Next, the roof underlayment 3 is covered with the roof material 6. Here, the blocking wall fixing portion 12 of this embodiment is longer than the thickness of the roof material 6 in the height direction z. Also, the water drain placement portion 13 is arranged opposite the side end covering portion 1b in the height direction z. Therefore, as shown in FIG. 2, the roof material 6 covers the roof underlayment 3 with the side end 60 being arranged between the water drain placement portion 13 and the side end covering portion 1b. Thus, the water drain member 5 is arranged between the roof underlayment 3 and the roof material 6, and the side end 60 is covered by the side end covering portion 1b. In this manner, the roof structure 2 of this embodiment is constructed.

As shown in FIG. 1, the roof structure 2 of this embodiment has a solar cell module 4 and a roof material 6 arranged on a roof base 3. Also, as shown in FIGS. 1 and 2, in the roof structure 2 of this embodiment, the water drainage member 5 is arranged at the boundary between the solar cell module 4 and the roof material 6. Specifically, in the longitudinal direction Y, the blocking wall portion 5b is arranged between the roof material 6 and the solar cell module 4.

As described above, according to this embodiment, the blocking protrusion 5c1 and the side end cover portion 1b come into contact with each other in the vertical direction Z, so that the roofing material protector 1 can be positioned in the vertical direction Z relative to the water draining member 5 by engagement. In addition, in this embodiment, the blocking protrusion 5c1 and the side end cover portion 1b come into contact with each other in the vertical direction Z, so that the roofing material protector 1 can be prevented from moving in the vertical direction Z relative to the water draining member 5. This allows the adhesion between the water draining mounting portion 13 and the blocking mounting portion 5d to be maintained, and prevents a decrease in the fixing strength between the water draining mounting portion 13 and the blocking mounting portion 5d.

Here, in this embodiment, asphalt shingles are used as the roofing material 6. As this is a soft material compared to, for example, slate or metal, the roofing material 6 of this embodiment is easy to cut on-site. Therefore, for example, when a worker uses scissors or the like on-site to cut the roofing material 6, a slight step may be formed in the side end 60 of the cut roofing material 6 in the length direction x. Even in such a case, the side end covering portion 1b covers the side end 60 of the roofing material 6 from above, thereby hiding the step in the side end 60 of the roofing material 6 and improving the appearance of the roof.

In addition, in this embodiment, for example, when the roof material 6 moves in the vertical direction Z due to strong winds, the blocking protrusion 5c1 holds the roof material protector 1 in the vertical direction Z, thereby preventing the roof material protector 1 from rattling. Therefore, the side end cover portion 1b of the roof material protector 1 held down by the blocking protrusion 5c1 can prevent the roof material 6 from being turned up.

In addition, in this embodiment, the drain fixing part 11 is adhesively fixed to one of the drain parts 5A, so that the roofing material protector 1 can be fixed to the drain member 5. Specifically, the blocking fixing surface 12a can be adhesively fixed to the blocking wall surface 5c, and the blocking connection surface 5e can be adhesively fixed to the drain placement part 13.

In addition, in this embodiment, the roofing material protector 1 is constructed by bending a plate-shaped member (specifically, a metal plate) that extends in the width direction y and the length direction x. Therefore, the side end cover portion 1b and the drain fixing portion 11 are constructed integrally. Therefore, for example, when the roofing material protector 1 is installed on the roof structure 2, or when an earthquake occurs after installation, the roofing material protector 1 can be prevented from coming apart.

Next, as shown in FIG. 3, a roof structure 2 according to a second embodiment will be described. Note that in describing the second embodiment, the same configuration and function as the first embodiment will not be described.

The blocking protrusion 5c1 of the second embodiment is disposed closer to the blocking placement portion 5d in the height direction z than the blocking protrusion 5c1 of the first embodiment. Specifically, the blocking protrusion 5c1 of the second embodiment is formed on a portion of the blocking wall surface 5c that faces the blocking fixed surface 12a in the girder direction Y when the drain placement portion 13 is placed on the blocking placement portion 5d. Also, the blocking fixed surface 12a of the second embodiment is formed with a through hole 12b that penetrates in the width direction y. This through hole 12b is configured so that the blocking protrusion 5c1 can be inserted therethrough.

Therefore, as shown in FIG. 3, in the second embodiment, when the roofing material protector 1 is installed on the water draining member 5, the blocking protrusion 5c1 is inserted into the through hole 12b in the girder direction Y. Therefore, the water draining member 5 and the roofing material protector 1 can be engaged. Therefore, the roofing material protector 1 can be positioned relative to the water draining member 5 in the vertical direction Z. In addition, since the blocking protrusion 5c1 is inserted into the through hole 12b, the movement of the roofing material protector 1 relative to the water draining member 5 in the vertical direction Z can be prevented, so that the adhesion between the water draining placement portion 13 and the blocking placement portion 5d can be maintained. Therefore, the fixing strength between the water draining placement portion 13 and the blocking placement portion 5d can be prevented from decreasing. Furthermore, as shown in FIG. 3, the blocking protrusion 5c1 may be arranged between multiple roofing materials 6. In this case, for example, when the roofing material 6 moves in the vertical direction Z due to a strong wind, the blocking protrusion 5c1 can prevent the roofing material 6 from being turned up. In addition, to avoid interference between the blocking protrusion 5c1 and the roof material 6, for example, the blocking protrusion 5c1 inserted into the through hole 12b may be bent in the vertical direction Z or in the eaves-ridge direction Xa.

Next, as shown in FIG. 4, a roof structure 2 according to a third embodiment will be described. In describing the third embodiment, the same configurations and functions as those of the first and second embodiments will not be described.

The third embodiment differs from the first and second embodiments in that a blocking protrusion 5e1 is formed on the blocking mounting portion 5d. Specifically, the blocking protrusion 5e1 of the third embodiment protrudes upward in the height direction z from the blocking connection surface 5e. Also, the blocking protrusion 5e1 of the third embodiment is formed on a portion of the blocking connection surface 5e that faces the drain mounting portion 13 in the up-down direction Z when the blocking wall fixing portion 12 abuts against the blocking wall portion 5b. Furthermore, in the third embodiment, a through hole 13b that penetrates the drain mounting portion 13 in the height direction z is formed. This through hole 13b is configured so that the blocking protrusion 5c1 can be inserted therethrough.

As described above, according to the third embodiment, when the roofing material protector 1 is installed on the water drainage member 5, the blocking protrusion 5e1 is inserted into the through hole 13b in the vertical direction Z. Therefore, the water drainage member 5 and the roofing material protector 1 can be engaged. Therefore, the roofing material protector 1 can be positioned relative to the water drainage member 5 in the girder direction Y. In addition, since the blocking protrusion 5e1 is inserted into the through hole 13b, the movement of the roofing material protector 1 relative to the water drainage member 5 in the girder direction Y can be prevented, so that the adhesion between the blocking fixing surface 12a and the blocking wall surface 5c can be maintained. Therefore, the fixing strength between the water drainage placement portion 13 and the blocking placement portion 5d can be prevented from decreasing. Furthermore, as shown in FIG. 4, in the third embodiment, the roofing material 6 arranged between the side end cover portion 1b and the water drainage placement portion 13 is placed on the blocking protrusion 5e1. This reduces the distance between the roof material 6 and the side end covering portion 1b in the vertical direction Z, and reduces the range of movement of the roof material 6 in the vertical direction Z, which can prevent the roof material 6 from being turned up by strong winds, for example. In addition, to avoid interference between the blocking protrusion 5e1 and the roof material 6, for example, the blocking protrusion 5e1 inserted into the through hole 13b may be bent in the girder direction Y or the ridge direction Xa.
