Description

The present invention relates to roofing material protection equipment.

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

However, there are cases where the mounting bottom part is fixed to the bottom of the recessed part using, for example, an adhesive. In this case, there is a risk that the mounting bottom part may become loose when blown by a strong wind. When the mounting bottom part becomes loose, the holding member rattles against the water receiving material, causing the bonding material to float up. This causes the fitting protrusion to come out of the engagement recess, exposing the seam of the outer panel. Therefore, when the mounting bottom part becomes loose from the bottom, water can enter the recessed part through the exposed seam of the outer panel.

It is also possible to fix the bottom surface portion to the bottom using a screw. However, in this case, the screw needs to penetrate the bottom, and there is a risk of water leaking into the base material from the part of the bottom where the screw penetrates.

The present invention aims to provide a roofing material protector that can prevent the roofing material from coming off the drainage member.

The present invention is a roof structure comprising a roof underlayment, a plate-shaped water drainage member placed on the roof underlayment, and a roofing material covering the roof underlayment. The roofing material protector is applied to a roof structure in which the side end of the roofing material is arranged opposite the water drainage member in the vertical direction, and the roofing material protector comprises a side end covering portion that covers the side end of the roofing material, a water drainage fixing portion that is adhesively fixed to the water drainage member, and a base fixing portion that is fixed using a fastener to an area of the roof underlayment where the water drainage member is not placed.

According to the above configuration, the side ends of the roofing material can be covered with the side end covering parts, thereby hiding the side ends; the roofing material protector can be fixed to the drainage member by adhesively fixing the drainage fixing parts to the drainage member; and the base fixing parts can be fixed to the roof base in an area where the drainage member is not placed using the fasteners, thereby fixing the roofing material protector to the roof base and preventing it from moving.

In addition, in the present invention, the base fixing portion may be in a position to be covered by the roofing material when the side end covering portion covers the side end of the roofing material.

According to the above configuration, when the side end covering portion covers the side end of the roofing material, the base fixing portion is in a position covered by the roofing material. Therefore, for example, the roofing material can protect the base fixing portion and the roof base to which the base fixing portion is fixed from rainwater, thereby preventing deterioration of the roof base around the fastener and preventing the roofing material protector from becoming easily detached from the water drainage member.

The present invention may also include a pushing part that pushes the drainage member toward the roof underlayment when the underlayment fixing part is fixed to an area of the roof underlayment where the drainage member is not placed.

According to this configuration, when the underlayment fixing portion is fixed to an area of the roof underlayment where the water drainage member is not placed, the pushing portion pushes the water drainage member toward the roof underlayment, thereby preventing the water drainage member from moving relative to the roof underlayment.

In addition, in the present invention, the side end covering portion, the drain fixing portion, the base fixing portion, and the pressing portion may be integrally configured.

According to the above configuration, the side end covering portion, the water drain fixing portion, the base fixing portion, and the pushing portion are configured as a single unit, so that, for example, the side end covering portion, the water drain fixing portion, the base fixing portion, and the pushing portion can be prevented from becoming separated, making it easy to apply to the roof structure.

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 side end covering portion can effectively prevent the roof material from being lifted up by strong winds, for example.

In addition, in the present invention, the base fixing portion may be provided in a plurality of portions spaced apart in the span direction.

According to the above configuration, since the substrate fixing parts are provided at intervals in the span direction, the substrate fixing parts can be fixed at multiple locations, and the roofing material protector can be further fixed to the roof substrate and prevented from moving.

In addition, in the present invention, the roof structure includes a solar cell module placed on the roof substrate, the water drainage member includes a base portion and a blocking wall portion rising from the base portion, the roof material is disposed on one side of the blocking wall portion in the girder direction, the solar cell module is disposed on the other side of the blocking wall portion in the girder direction, and the water drainage fixing portion may have a blocking wall fixing portion that is adhesively fixed to the blocking wall portion from one side in the girder direction.

According to the above configuration, the blocking wall fixing portion is adhesively fixed to the blocking wall portion from one side in the girder direction, thereby preventing the roofing material protector from separating from the blocking wall portion in the girder direction.

As described above, according to the present invention, the roofing material protector can be fixed to the roof base and immobilized, so that the roofing material can be prevented from coming off the water drainage member.

FIG. 1 is a plan view of a roof structure according to an embodiment of the present invention. FIG. 2 is a plan view of the roof structure according to the embodiment, showing a protective fixing portion with a part of the roof material cut away. FIG. 3 is a cross-sectional view of the roof structure according to the embodiment taken along line III-III in FIG.

The following describes a roofing material protector 1 according to one 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 FIG. 3 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.

For ease of explanation, the roof structure 2 will be described first. In this embodiment, the roof structure 2 is described as being inclined downward from the ridge side to the eaves side. Therefore, the spanning direction X is the eaves-ridge direction Xa along which the rafters extend. In addition, for the roof structure 2 that is inclined downward from the ridge side to the eaves side, it is preferable for the inclination angle to be 14 degrees (2.5 inch gradient) 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, and a roof material 6.

The roof underlayment 3 extends in the width direction y and the length direction x. As shown in FIG. 2, the roof underlayment 3 of this embodiment 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. 3, the roof underlayment 3 of 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. 3, 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 410 and a mounting body portion 411.

The panel support section 410 is primarily intended to support the solar cell panel 40 from below. As shown in FIG. 3, the panel support section 410 in this embodiment is positioned inward (to the right in FIG. 3) from the solar cell 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 410. The mounting body 411 of this embodiment is longer than the panel support 410 in the width direction y. Therefore, as shown in FIG. 3, the mounting body 411 faces the lower surface (not numbered) of the solar cell panel 40 in the height direction z. Also, as shown in FIGS. 2 and 3, the mounting body 411 of this embodiment extends outward (to the left in FIGS. 2 and 3) from the solar cell panel 40 in the width direction y. Furthermore, the mounting body 411 of this embodiment has a folded portion 412 by folding back the end on the outer side in the width direction y.

As described above, the panel support part 410 of this embodiment is disposed inward (to the right in FIG. 3) from the solar cell panel 40 in the width direction y. The mounting body part 411 of this embodiment is longer than the panel support part 410 in the width direction y and faces the underside of the solar cell panel 40. Therefore, as shown in FIG. 3, the solar cell module 4 of this embodiment has a gap space 413 defined by the underside of the solar cell panel 40, the end face (not numbered) of the panel support part 410 in the width direction y, and the mounting body part 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). As shown in FIG. 2, the drain body 50 is plate-shaped and extends in the width direction y and the length direction x. As shown in FIGS. 2 and 3, the drain body 50 of this embodiment is shorter in the width direction y than the mounting body 411. The drain body 50 of this embodiment also includes a substantially flat base portion 500 and a folded portion 505 formed at the end in the width direction y.

2, 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 base portion 500 in the width direction y. As shown in FIG. 3, the base portion 500 is formed with a protrusion portion 501 that protrudes upward. In this embodiment, the protrusion portion 501 is formed by bending the base portion 500 in the width direction y. Therefore, in this embodiment, the protrusion portion 501 is formed over the entire area of the base portion 500 in the length direction x. In this embodiment, multiple (specifically, eight) protrusion portions 501 are formed in the width direction y.

2 and 3, in the base portion 500 of this embodiment, a base region 502 is formed between two adjacent protrusions 501 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. In this embodiment, the drainage area 503 is longer than the adhesive area 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. As shown in Figures 2 and 3, the folded-back portion 505 in this embodiment is disposed at 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. 3, the blocking portion 5a in this embodiment is formed by bending a plate-shaped member (specifically, a metal plate) that extends 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 connection portion 5d.

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. 3, the blocking wall portion 5b has a blocking wall surface 5c on one side in the width direction y (the left side in FIGS. 1, 2, and 3). 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 interruption connection portion 5d is used when connecting the interruption portion 5a to the drain body portion 50. As shown in FIG. 2, the interruption connection portion 5d extends in the width direction y and the length direction x. Also, as shown in FIG. 3, the interruption connection portion 5d is connected to one end (lower end) of the interruption wall portion 5b in the height direction z. Therefore, the interruption connection portion 5d of this embodiment is arranged so as to be perpendicular to the interruption wall portion 5b. The interruption connection portion 5d of this embodiment is provided on one side and the other side of the width direction y of the interruption wall portion 5b. Also, in this embodiment, the interruption connection portion 5d arranged on one side of the width direction y has an interruption 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 interruption connection portion 5d of this embodiment is shorter than the base region 502 in the width direction y. Therefore, the interruption 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 connection part 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 blocking connection part 5d on the base region 502 of the base part 500 with the width direction y of the blocking part 5a aligned with the width direction y of the draining body part 50, and fixing the blocking connection part 5d to the base region 502. Therefore, the blocking wall part 5b stands up from the base part 500. In addition, in this embodiment, by placing the blocking part 5a on the draining body part 50, the draining member 5 is divided into one draining part 5A on one side of the width direction y and the other draining part 5B on the other side of the width direction y, with the blocking wall part 5b as the boundary in the width direction y. As shown in FIG. 2, in this embodiment, the one draining part 5A is shorter than the other draining part 5B in the width direction y to prevent the base part 500 from being placed on the folded part 412 and causing a problem.

The roofing material 6 covers the roof underlay 3 and prevents rainwater from penetrating into the roof underlay 3. In this embodiment, the roofing material 6 is made of a softer material than hard materials such as slate or metal. Specifically, in this embodiment, asphalt shingles are used as the roofing material 6. 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. As shown in FIG. 1, in this embodiment, multiple roofing materials 6 are arranged in a checkerboard pattern and cover the roof underlay 3.

In the above roof structure 2, first, as shown in Figure 3, a waterproof roofing sheet 31 is placed on the sheathing board 30 to form the roof foundation 3. Next, as shown in Figures 1 to 3, the width direction y of the solar cell module 4 is aligned with the girder direction Y, the length direction x is aligned with the ridge direction Xa, and the height direction z is aligned with the up-down direction Z so that the solar cell panel 40 is positioned above the panel mounting part 41, and the mounting body part 411 is placed on the roofing sheet 31. In this way, the solar cell module 4 is 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 vertical 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, the drainage body 50 can be placed on the mounting body 411. Specifically, as shown in Figures 2 and 3, 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, as shown in Figure 3, the drainage member 5 is placed on the mounting body 411, so that the blocking wall portion 5b is placed opposite the solar cell panel 40 in the girder direction Y. Therefore, the blocking wall portion 5b blocks the gap space 413 from one side in the girder direction Y. In particular, since the blocking wall portion 5b in this embodiment is a plate-like shape that extends in the height direction z and the length direction x, it can block the gap space 413 over a wide range in the eaves-ridge direction Xa. Therefore, the blocking portion 5a can prevent rainwater, birds, and insects from entering the gap space 413 from one side in the girder direction Y. Thus, in this embodiment, the water drainage member 5 is placed on the roof underlayment 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.

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 to 3, 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.

Next, we will explain the roofing material protector 1.

The roofing material protector 1 is used, for example, to protect the roofing material 6 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. 3, the roofing material protector 1 of this embodiment is constructed by bending a plate-shaped member into a roughly U-shape. The roofing material protector 1 includes a protective main body portion 1a and a protective fixing portion 10.

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 the side end 60 of the roofing material 6 from above. The side end covering portion 1b extends in the length direction x and the width direction y. As shown in FIG. 2, the side end covering portion 1b of this embodiment 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. 3, the length in the width direction y of the side end covering portion 1b of this embodiment is shorter than the length in the width direction y of the roofing material 6.

As shown in FIG. 3, 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 protective fixing part 10 is used to fix the roofing material protector 1 to the water drainage member 5 and the roof underlayment 3. The protective fixing part 10 includes a water drainage fixing part 11 and a underlayment fixing part 14.

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 wall fixing portion 12 is used to adhesively fix the roofing material protector 1 to the barrier wall portion 5b. As shown in FIG. 3, the barrier wall fixing portion 12 extends in the height direction z. The barrier wall 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 wall 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 of the width direction y. As shown in FIG. 3, the barrier wall fixing portion 12 of this embodiment is disposed lower than the side end covering portion 1b in the height direction z. Specifically, the barrier wall 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 length of the barrier wall fixing portion 12 in the height direction z is longer than the thickness of the roofing material 6. Note that, as shown in FIG. 3, the barrier wall fixing portion 12 of this embodiment is longer than the thickness of multiple (specifically, two) roofing materials 6 in the height direction z. Furthermore, in this embodiment, the blocking wall fixing portion 12 is shorter than the blocking wall portion 5b in the height direction z.

The drain placement portion 13 is placed on the drain member 5. In this embodiment, the drain placement portion 13 is adhesively fixed to the drain member 5. As shown in Figures 2 and 3, the drain placement portion 13 includes a cutoff connection fixing portion 13a and a connecting portion 13b arranged in the width direction y.

The interruption connection fixing part 13a is placed on the interruption connection part 5d. The interruption connection fixing part 13a extends in the width direction y. As shown in FIG. 2, the interruption connection fixing part 13a of this embodiment is rectangular in shape with a length in the length direction x longer than the length in the width direction y. The interruption connection fixing part 13a of this embodiment is longer than the side end covering part 1b in the width direction y. The interruption connection fixing part 13a of this embodiment is continuous with one end (lower end) of the interruption wall fixing part 12 in the height direction z. Therefore, the interruption connection fixing part 13a is disposed on one side of the interruption wall fixing part 12 in the width direction y. Therefore, as shown in FIG. 3, the interruption connection fixing part 13a is disposed opposite the side end covering part 1b in the height direction z.

The spanning portion 13b spans the interrupt connection fixing portion 13a and the base fixing portion 14 described below. As shown in FIG. 2, the spanning portion 13b in this embodiment is rectangular in shape with a length in the width direction y longer than its length in the length direction x. The spanning portion 13b is disposed on one side in the width direction y of the interrupt connection fixing portion 13a. The spanning portion 13b in this embodiment is continuous with one end of the interrupt connection fixing portion 13a in the width direction y. Furthermore, the spanning portion 13b in this embodiment is shorter in the length direction x than the interrupt connection fixing portion 13a.

The base fixing portion 14 is for fixing the roofing material protector 1 to the roof base 3. As shown in FIG. 2, the base fixing portion 14 is rectangular and extends in the width direction y and the length direction x. The base fixing portion 14 is disposed on one side of the span portion 13b in the width direction y. The base fixing portion 14 of this embodiment is continuous with one end of the span portion 13b in the width direction y. As shown in FIG. 3, the base fixing portion 14 of this embodiment is configured to be inclined downward in the width direction y as it moves away from the span portion 13b. In addition, the base fixing portion 14 of this embodiment has a through hole 14A that penetrates in the height direction z.

As shown in Figures 2 and 3, in the roofing material protector 1 of this embodiment, the total length in the width direction y of the drain placement portion 13 and the base fixing portion 14 is longer than the length in the width direction y from the blocking wall surface 5c of the blocking wall portion 5b to the folded portion 505.

In this embodiment, the barrier wall fixing part 12 is continuous with the other end of the side end covering part 1b in the width direction y, the barrier connection fixing part 13a is continuous with one end (lower end) of the barrier wall fixing part 12 in the height direction z, the spanning part 13b is continuous with one end of the barrier connection fixing part 13a in the width direction y, and the base fixing part 14 is continuous with one end of the spanning part 13b in the width direction y. Thus, in this embodiment, the side end covering part 1b, the barrier wall fixing part 12 as the drainage fixing part 11, the barrier connection fixing part 13a and the spanning part 13b, and the base fixing part 14 are integrally configured.

The roofing material protector 1 configured as described above is applied to the roof structure 2. The roofing material protector 1 is installed on the drainage member 5 before covering the roof underlayment 3 with the roofing material 6. The roofing material protector 1 of this embodiment is installed on one drainage section 5A of the drainage member 5. Specifically, as shown in FIG. 3, 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 protective fixing section 10.

As shown in FIG. 3, before the roofing material protector 1 is installed, adhesive is applied to the adhesive area 504, the blocking connection surface 5e, and the blocking wall surface 5c of the water drainage member 5.

In this embodiment, the protective body 1a is positioned below the blocking wall 5b, and the blocking wall fixing part 12 is abutted against the blocking wall 5b, and the drain placement part 13 is placed on the one-side drain part 5A. Specifically, the blocking fixing surface 12a is adhesively fixed to the blocking wall surface 5c, the spanning part 13b is placed on the folded part 505 and the protruding part 501, and is adhesively fixed to the adhesive area 504, and the blocking connection fixing part 13a is adhesively fixed to the blocking connection surface 5e. In this way, the roofing material protector 1 is installed on the one-side drain part 5A.

Here, in the roofing material protector 1 of this embodiment, the sum of the lengths in the width direction y of the drain placement portion 13 and the base fixing portion 14 is longer than the length in the width direction y from the blocking wall surface 5c of the blocking wall portion 5b to the folded portion 505. Therefore, as shown in Figures 2 and 3, when the roofing material protector 1 is installed on one of the drain sections 5A, the base fixing portion 14 is positioned on one side of the folded portion 505 in the girder direction Y. Specifically, the base fixing portion 14 of this embodiment is positioned in an area of the roof base 3 in the girder direction Y where the drain member 5 is not placed.

Then, the base fixing part 14 is fixed to the roof underlayment 3 using the fastener A. In this embodiment, the fastener A, which is a nail or a screw, is inserted into the through hole 14A of the base fixing part 14 to fix the base fixing part 14 to an area of the roof underlayment 3 where the water drainage member 5 is not placed. Here, as the base fixing part 14 is fixed to the roof underlayment 3, the water drainage placement part 13, which has the cross part 13b that is continuous with the base fixing part 14, is pressed downward. Therefore, the cross part 13b presses the folded part 505 and the protruding part 501 downward. Therefore, the water drainage placement part 13 presses the water drainage member 5 toward the roof underlayment 3. Therefore, the water drainage placement part 13 has a pushing part 13c that pushes the water drainage member 5 toward the roof underlayment 3. Specifically, the pushing part 13c in this embodiment is the part of the cross part 13b that is placed on the folded part 505 and the protruding part 501. In this way, the roofing material protector 1 is fixed to the water drainage member 5 and the roof underlayment 3.

Next, the roof underlayment 3 is covered with the roofing material 6. Here, as shown in FIG. 3, the blocking wall fixing portion 12 of this embodiment is longer than the thickness of the roofing material 6 in the height direction z. Also, the blocking connection fixing portion 13a is arranged opposite the side end covering portion 1b in the height direction z. Therefore, the roofing material 6 covers the roof underlayment 3 so that the side end 60 is arranged between the blocking connection fixing portion 13a and the side end covering portion 1b. Therefore, the side end 60 is covered by the side end covering portion 1b. Furthermore, in this embodiment, the lower end surface of the roofing material 6 is placed on the blocking connection fixing portion 13a and the cross portion 13b, and the roofing material 6 covers the water drain placement portion 13 and the underlayment fixing portion 14. Therefore, when the side end covering portion 1b covers the side end 60 of the roofing material 6, the underlayment fixing portion 14 is arranged in a position covered by the roofing material 6. In this way, the roofing material protector 1 of this embodiment is applied to the roof structure 2.

As described above, according to this embodiment, as shown in FIG. 3, the side end covering portion 1b covers the side end 60 of the roofing material 6 from above, so that the side end 60 can be hidden by the side end covering portion 1b as shown in FIGS. 1 and 2.

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, the length of the side end covering portion 1b in the width direction y in this embodiment is shorter than the length of the roof material 6 in the width direction y. Therefore, when the side end covering portion 1b covers the side end 60 of the roof material 6 from above, the side end covering portion 1b can be made less noticeable, improving the appearance of the roof.

In addition, in this embodiment, the drain fixing portion 11 is adhesively fixed to one drain portion 5A, so that the roofing material protector 1 can be fixed to the drain member 5. Specifically, the blocking fixing surface 12a is adhesively fixed to the blocking wall surface 5c, the bridge portion 13b is fixed to the adhesive region 504, and the blocking connection fixing portion 13a is adhesively fixed to the blocking connection surface 5e. Therefore, the roofing material protector 1 can be adhesively fixed to the drain member 5 in the vertical direction Z and the girder direction Y, which are in an intersecting relationship, and the roofing material protector 1 can be prevented from moving in the vertical direction Z and the girder direction Y.

In addition, in this embodiment, the drain fixing portion 11 is formed by adhesively fixing the blocking fixing surface 12a to the blocking wall surface 5c, fixing the bridge portion 13b to the adhesive region 504, and adhesively fixing the blocking connection fixing portion 13a to the blocking connection surface 5e. Therefore, the roofing material protector 1 can be adhesively fixed to the draining member 5 at multiple points, so that the roofing material protector 1 can be more firmly fixed to the draining member 5.

In addition, in this embodiment, the underlayment fixing portion 14 is fixed using the fastener A to the area of the roof underlayment 3 where the water drainage member 5 is not placed, so that the roofing material protector 1 can be fixed to the roof underlayment 3 and cannot move. Here, by fixing the underlayment fixing portion 14 to the area of the roof underlayment 3 where the water drainage member 5 is not placed, the bridge portion 13b connected to the underlayment fixing portion 14 presses the folded portion 505 and the protruding portion 501 downward. Therefore, the pushing portion 13c provided on the water drainage placement portion 13 can push the water drainage member 5 toward the roof underlayment 3. Therefore, the water drainage member 5 can be prevented from moving relative to the roof underlayment 3.

As shown in FIG. 3, when the roofing material protector 1 of this embodiment is applied to the roof structure 2, the base fixing part 14 is disposed in the area of the roof base 3 in the girder direction Y where the water drainage member 5 is not placed. Here, the drainage area 503 of this embodiment guides water throughout the entire length direction x. Therefore, for example, water guided by the drainage area 503 in the eaves-ridge direction Xa can be prevented from flowing into the base fixing part 14, and deterioration of the roof base 3 around the fastener A can be prevented.

In addition, according to this embodiment, when the roofing material protector 1 is applied to the roof structure 2, the lower end surface of the roofing material 6 is placed on the blocking connection fixing part 13a and the spanning part 13b, and the base fixing part 14 is disposed below the roofing material 6. Therefore, the weight of the roofing material 6 transmitted to the blocking connection fixing part 13a and the spanning part 13b also presses the base fixing part 14, which is continuous with one end of the spanning part 13b in the width direction y, downward, so that the roofing material protector 1 can be further prevented from moving.

In addition, in this embodiment, since the bridge portion 13b is placed on the protrusion portion 501, the bridge portion 13b can be prevented from interfering with the flow of water in the eaves-ridge direction Xa guided by the drainage area 503.

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, the gutter fixing portion 11, and the base fixing portion 14 are constructed as a single unit. 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.
