Description

Application of Article 30, Paragraph 2 of the Patent Act Riken Light Metals Industry Co., Ltd. disclosed the present invention in a product flyer titled “Eyelash” published on November 1, 2021.

This invention relates to building eaves that are attached to the eaves of a building, and in particular to building eaves that slope upwards gradually toward the front, so-called reverse slope eaves.

One example of this type of eaves is proposed in Patent Document 1. This eaves is constructed by holding the base end of the eaves plate with a retainer so that the eaves plate protrudes forward from the exterior wall surface of the building. The retainer has a retaining frame material with a horizontal plate part that supports the underside of the base end of the eaves plate over its entire width, which is integrated with a vertical plate part fixed to the exterior wall surface of the building, a wedge plate that is interposed so that the rear surface of the vertical plate part of the retaining frame material and the exterior wall surface of the building contact each of the front and rear surfaces, and tilts the vertical plate part with respect to the vertical plane so that the eaves plate is inclined downward to the rear, and a rain gutter that is connected to the lower end of the wedge plate and positioned below the horizontal plate part of the retaining frame material. A drainage hole that communicates with the rain gutter is formed in the horizontal plate part of the retaining frame material.

JP 2012-77468 A

However, the configuration described in the above-mentioned Patent Document 1 has a problem in that the gutter is provided integrally with the wedge plate, and the wedge plate and the gutter cannot be replaced without removing the retaining frame material, so that the gutter alone cannot be replaced. Also, if the screw fixing the wedge plate is damaged, there is a risk that the gutter will slip downward and fall off.
Therefore, an object of the present invention is to provide a building eave that allows one person to easily install gutters and replace parts.

In order to solve the above problems, the present invention comprises a base frame attached to the building structure, an eaves plate supported by the base frame, and a horizontal gutter positioned below the eaves plate and extending in the width direction. When the horizontal direction in which the eaves plate protrudes is the front and the building structure side as seen from the eaves plate is the rear, the eaves plate is supported by the base frame so that it slopes upwards as it moves forward, and the horizontal gutter is configured to be able to slide from the front to the rear and engage with the base frame.

As described above, the present invention allows the gutter to be slid from front to rear and engaged with the base frame, so that installation and replacement of the gutter can be easily performed by one person. In other words, when installing the gutter, it can be slid from front to rear to temporarily secure the gutter, making installation easy. In addition, when removing the gutter, it can be removed by sliding it forward, so that only the gutter can be easily replaced.

An embodiment of the present invention will be described with reference to the drawings. In the following description, the horizontal direction in which the eaves plate 11 protrudes is referred to as the front, and the building structure side (the opposite direction to the front) as viewed from the eaves plate 11 is referred to as the rear. This front-to-rear direction is referred to as the depth direction D of the building eaves 10, and the horizontal direction perpendicular to the depth direction D is referred to as the width direction W. The vertical direction is referred to as the height direction H (up-down direction).

The building eaves 10 according to this embodiment is attached to the eaves of a building to block direct sunlight, rainwater, etc., and includes an eaves plate 11, a base frame 20, a base angle 21, a base cover 23, a base lid 25, a tip frame 28, a tip cover 29, a tip lid 30, a drain section 31, a gutter bracket 35, a gutter 36, a gutter lid 37, a gutter cover 38, and a downspout 39, as shown in Figures 1 and 2.

The eaves plate 11 is formed by joining multiple eaves materials 12 in the width direction W. In this embodiment, the eaves plate 11 is formed by combining a left eaves material 14 used at the left end of the eaves plate 11, a right eaves material 15 used at the right end of the eaves plate 11, and an intermediate eaves material 13 arranged between the left eaves material 14 and the right eaves material 15. The width of the eaves plate 11 can be adjusted by increasing or decreasing the number of intermediate eaves materials 13. These three types of eaves materials 12 are hollow, long materials as shown in Figure 3, for example, extruded aluminum materials. These eaves materials 12 are all formed to the same length, and the height dimensions (thickness) at the top and bottom are set to be approximately the same.

The base frame 20 is a member for supporting the eaves plate 11 and other components, and is attached to the wall surface 70 of the building frame as shown in Figure 2. This base frame 20 is a long member with a width equal to or greater than that of the eaves plate 11. As shown in Figure 2, the base frame 20 of this embodiment is fixed to the wall surface 70 of the building by mounting bolts 20a and mounting nuts 20b that are attached to the wall surface 70 in advance. The eaves plate 11 is attached to the front of this base frame 20. The base frame 20 of this embodiment supports the eaves plate 11 so that it slopes upward as it goes forward.

The base angle 21 is a member that cooperates with the base frame 20 to support the eaves material 12. Specifically, as shown in FIG. 2, the eaves material 12, whose underside is supported by the base frame 20, is held down from above by the base angle 21, and the base frame 20 and the base angle 21 support the eaves material 12 by sandwiching it from both the top and bottom. As shown in FIG. 7, a base angle 21 is provided for each eaves material 12, and the same number of base angles 21 are used as the number of eaves materials 12. Note that the base angles 21 in this embodiment are provided so as to straddle adjacent eaves plates 11, so there may be fewer base angles than eaves plates 11 (for example, one for every two eaves plates 11).

The base cover 23 is a cover member that is attached to cover the top surfaces of the base frame 20 and the base angle 21. This base cover 23 prevents rainwater from falling directly onto the base frame 20 and the base angle 21. This base cover 23 is inclined so that rainwater flows forward toward the eaves material 12. The rear end of this base cover 23 is fixed to the base frame 20 by base cover screws 24, and the front end is hooked between the tip of the base angle 21 and the upper surface of the eaves plate 11.

The base lid 25 is a cover member that is attached to the side end (small edge) of the base frame 20. This base lid 25 is fixed to both ends of the base frame 20 with screws or the like.

The tip frame 28 is a member for attaching the tip cover 29 (described later) to the eaves plate 11. The tip frame 28 in this embodiment is a long member with a generally L-shaped cross section. This tip frame 28 is attached to the tip of the eaves plate 11 with tip frame screws 28a.

The tip cover 29 is a long cover material that covers the tip of the eaves plate 11. This tip cover 29 is attached to the tip frame 28 by tip cover screws 29a.

The tip lid 30 is a cover member that is attached to the side end (small end) of the tip cover 29. The tip lid 30 is fixed to both ends of the tip cover 29 with screws or the like.

The drain section 31 is for draining water that accumulates on the upper surface of the eaves plate 11 downward. The eaves plate 11 has a mounting hole 12c that penetrates vertically (see FIG. 6. The same shaped mounting hole 12c is formed in the upper plate portion 40 and the lower plate portion 41 described later), and by attaching the drain section 31 to this mounting hole 12c, water can be drained to the underside of the eaves plate 11. In addition, since the eaves plate 11 in this embodiment is inclined so that the front side is higher, rainwater received by the eaves plate 11 flows backward. For this reason, as shown in FIG. 8, the drain section 31 is provided near the rear end 11a of the eaves plate 11, so that rainwater that flows backward along the inclination of the eaves plate 11 can be drained downward.

The gutter bracket 35 is a member for attaching the gutter 36 (described later) to the underside of the eaves plate 11. The gutter bracket 35 is fixed to the underside of the eaves plate 11 with a screw or the like, with its rear end engaged with the base frame 20.

The horizontal gutter 36 is for receiving rainwater and the like collected by the eaves plate 11, and is positioned below the eaves plate 11 and extends in the width direction W. The horizontal gutter 36 is set to be at least longer than the width of the eaves plate 11.

The gutter lid 37 is a cover member that is attached to the side end (small end) of the gutter 36. This gutter lid 37 is fixed to the gutter 36 with a screw or the like. As shown in Figure 1, this gutter lid 37 has a lid hole 37a formed in it to prevent overflow.

The gutter cover 38 is a cover material that covers the fixing points between the gutter 36 and the gutter bracket 35 so that they cannot be seen from the outside. This gutter cover 38 is fitted and attached to the upper end of the front of the gutter 36.

The downspout 39 is a pipe for discharging the rainwater collected by the horizontal gutter 36 to the ground. The downspout 39 is connected to the horizontal gutter 36 at an arbitrary location in a T-shape (or an inverted L-shape).
Next, the specific shape of the above-mentioned canopy material 12 will be described in detail.

As shown in FIG. 3, the eaves member 12 according to this embodiment has an upper plate portion 40 and a lower plate portion 41 that are parallel to each other, and the space between the upper plate portion 40 and the lower plate portion 41 is hollow. A plurality of vertical walls extending in the vertical direction are provided between the upper plate portion 40 and the lower plate portion 41. In this embodiment, the vertical walls include side wall portions 42 on both the left and right sides, and an intermediate wall portion 43 is provided between the side wall portions 42.

These eaves members 12 also have a first joint 50 or a second joint 60 on the side. In this embodiment, the middle eaves member 13 has a first joint 50 on the right side and a second joint 60 on the left side. The left eaves member 14 has a first joint 50 on the right side and a side end gutter 68 on the left side. The right eaves member 15 has a side end gutter 68 on the right side and a second joint 60 on the left side. Adjacent eaves members 12 are joined to each other by the engagement of the first joint 50 on one side and the second joint 60 on the other side. The side end gutter 68 on the left eaves member 14 and the right eaves member 15 is a groove that opens upward and is used to drain rainwater received by the eaves plate 11.

The first joint portion 50 is a modified, generally U-shaped portion that opens to the side as shown in Fig. 3. The first joint portion 50 includes a first side wall portion 52 that is the side wall portion 42 that defines the first joint portion 50, a first upper protrusion portion 51 that protrudes laterally beyond the first side wall portion 52 by extending the upper plate portion 40, and a first lower protrusion portion 53 that protrudes laterally beyond the first side wall portion 52 by extending the lower plate portion 41.
A rotation shaft portion 51a is formed at the tip of the first upper protrusion portion 51. At least the lower surface of the rotation shaft portion 51a is formed as a curved surface (preferably a semi-cylindrical curved surface).

In addition, an arc-shaped portion 52a is provided at the upper end of the first side wall portion 52 so as to be continuous with the lower surface of the upper plate portion 40. The arc-shaped portion 52a is formed in an arc shape that follows the circumferential surface of the rotating shaft portion 51a. With this configuration, an arc-shaped guide groove 52b is formed between the rotating shaft portion 51a and the arc-shaped portion 52a, and the rotating shaft portion 51a is disposed above this guide groove 52b.

The first side wall portion 52 has a straight portion 52d that extends almost vertically downward connected below the guide groove 52b (arc-shaped portion 52a). The straight portion 52d is connected below the straight portion 52d. The inclined portion 52c is inclined inward (opposite the opening direction of the first joint portion 50) as it extends downward.

The first lower protrusion 53 includes a flat plate portion 53a that is continuous with the lower plate portion 41, a rising portion 53b that extends upward from the end of the flat plate portion 53a, and an arc-shaped curved piece 53c that extends diagonally upward from the upper end of the rising portion 53b. The curved piece 53c is formed in an arc shape centered on the rotating shaft portion 51a below the rotating shaft portion 51a. Note that the curved piece 53c does not have to be completely arc-shaped centered on the rotating shaft portion 51a, as long as it has a shape that follows the outer periphery of the rotating shaft portion 51a.

The space surrounded by the first side wall portion 52 and the first lower protrusion portion 53 is a groove-like opening facing upward, forming an intermediate gutter portion 54 for receiving water that seeps in through the joined joint. This intermediate gutter portion 54 allows water to flow in the longitudinal direction of the eaves material 12. In this embodiment, a portion of the first side wall portion 52 is formed at an angle (has an inclined portion 52c), so the volume of the intermediate gutter portion 54 (the maximum volume of water that can be received by the gutter) is ensured to be large. In addition, the curved piece 53c protrudes to the side in an arc, so the volume of the intermediate gutter portion 54 is further ensured to be large.

Next, the second joint 60 that is joined to the first joint 50 will be described. As shown in FIG. 3, the second joint 60 is also a modified, generally U-shaped portion that opens to the side. The second joint 60 includes a second side wall 62 that is the side wall 42 that defines the second joint 60, a second upper protrusion 61 that protrudes laterally beyond the second side wall 62 by extending the upper plate 40, and a second lower protrusion 63 that protrudes laterally beyond the second side wall 62 by extending the lower plate 41.

A pivot receiver 61a is formed at the tip of the second upper protrusion 61. The pivot receiver 61a has an arc-shaped inner peripheral surface that opens upward. This pivot receiver 61a can support the pivot shaft 51a of the first joint 50 from below. This pivot receiver 61a can rotatably support the placed pivot shaft 51a. In addition, this pivot receiver 61a can be inserted into the guide groove 52b of the first joint 50. The guide groove 52b has the same arc shape as the pivot receiver 61a, so it can rotatably support the inserted pivot receiver 61a. With this configuration, the first joint 50 and the second joint 60 can be rotated relative to each other to easily join the eaves material 12. This joining method will be described in detail later.

The second side wall 62 also has a support groove 62a into which the tip of the curved piece 53c of the first joint 50 is inserted. When the first joint 50 and the second joint 60 are joined, the curved piece 53c is inserted into the support groove 62a, so that it can withstand loads in the up, down, left and right directions, thereby increasing the strength of the joint. In other words, since it is supported at two points, the pivot receiver 61a inserted into the guide groove 52b and the curved piece 53c inserted into the support groove 62a, it can be reinforced against loads in the up, down, left and right directions. In addition, as shown in Figures 4(d) and 5(d), a labyrinth shape is formed at the tip of the intermediate gutter 54, so that water is less likely to leak to the underside of the eaves material 12. The support groove 62a is formed slightly wider than the thickness of the curved piece 53c, so that the curved piece 53c is loosely fitted inside the support groove 62a. In other words, the curved piece 53c is inserted into the support groove 62a so that a gap is created around it. It is desirable that the support groove 62a and the curved piece 53c are formed so that they do not come into contact with each other when the first joint part 50 and the second joint part 60 are rotated to join them. By loosely fitting the curved piece 53c into the support groove 62a in this way, no force is required when joining or removing the eaves material 12, making the work easy.

In addition, an upwardly bent erected portion 63a is formed at the tip of the second lower protrusion 63. This erected portion 63a abuts against the rising portion 53b when the first joint portion 50 and the second joint portion 60 are joined. By this erected portion 63a abutting against the rising portion 53b, adjacent eaves members 12 are supported in a flat state. In addition, by forming this erected portion 63a, the space surrounded by the second side wall portion 62 and the second lower protrusion portion 63 has a groove shape, forming a secondary gutter portion 64. As shown in Figures 4(d) and 5(d), this secondary gutter portion 64 is arranged so as to overlap below the intermediate gutter portion 54, and can receive water that leaks outside the intermediate gutter portion 54. By providing this secondary gutter portion 64, even if water infiltrates the back side of the curved piece 53c, this water can be received.

The first joint 50 and the second joint 60 can be joined by rotating the first joint 50 as shown in FIG. 4. Also, the second joint 60 can be joined by rotating the second joint 60 as shown in FIG. 5.

When joining by rotating the first joint 50, first, as shown in FIG. 4(b), the first joint 50 is tilted diagonally and inserted from above into the second joint 60. Then, as shown in FIG. 4(c), the pivot shaft 51a is placed on the pivot receiver 61a. After that, as shown in FIG. 4(d), the first joint 50 is rotated around the pivot shaft 51a, and the rising portion 53b is brought into contact with the erected portion 63a. This operation joins two adjacent eaves materials 12 flat to each other. At this time, the curved piece 53c is automatically inserted inside the support groove 62a.

When the second joint 60 is rotated to join, first, as shown in FIG. 5(a), the second joint 60 is tilted diagonally and inserted from above into the first joint 50. Then, as shown in FIG. 5(b), the rotation receiver 61a is slid upward along the inclined portion 52c. Then, as shown in FIG. 5(c), the rotation receiver 61a fits into and gets caught in the guide groove 52b. After that, as shown in FIG. 5(d), the second joint 60 is rotated by inserting the rotation receiver 61a along the guide groove 52b, and the erected portion 63a is brought into contact with the rising portion 53b. Through this operation, two adjacent eaves members 12 are joined flat to each other. At this time, the curved piece 53c is automatically inserted inside the support groove 62a.

The first joint 50 and the second joint 60 described above are formed over the entire longitudinal length of the eaves material 12. Therefore, as shown in FIG. 6, after the first joint 50 and the second joint 60 are joined, the eaves material 12 can be slid in the depth direction D of the building eaves 10. Therefore, after joining the eaves material 12, it can be slid to the mounting position (towards the base frame 20) and fixed to the base frame 20, which provides good workability.

In addition, an irregular wood grain pattern 12a is formed on the underside of these eaves materials 12, as shown in FIG. 6. This wood grain pattern 12a is formed along the longitudinal direction of the eaves material 12, and a natural wood grain can be expressed by making the intervals and heights irregular. By forming the wood grain, the design of the wood grain can be utilized, and the joints between the eaves materials 12 become less noticeable, so the design is good. In addition, since the wood grain can be formed during extrusion molding, manufacturing is also easy. In this embodiment, the wood grain is formed along the direction of extrusion molding, but this is not limited to this, and the wood grain may be formed in a direction perpendicular to the direction of extrusion molding.
Next, the specific shapes of the base angle 21 and the base frame 20 will be described in detail.

The base angle 21 is a member attached to the base frame 20 to support the upper surface of the eaves plate 11, and is formed in a plate shape bent in a step-like shape as shown in FIG. 8. The base angle 21 has a hook portion 21a at the upper end, an arm portion 21b extending diagonally downward from the hook portion 21a, and an attachment portion 21c formed to protrude forward from the tip of the arm portion 21b. The hook portion 21a is a portion that is hooked to the inside of the locking piece 26a (described later) of the base frame 20. The hook portion 21a is inserted into the inside of the locking piece 26a of the base frame 20 from below, and is held down from above by the locking piece 26a. The attachment portion 21c is a portion that abuts against the upper surface of the eaves material 12 and holds down the upper surface of the eaves material 12 from above. The attachment portion 21c is fixed to the eaves material 12 by an eaves fixing device 22 described later. In addition, a cover engagement portion 21d is formed at the tip of the mounting portion 21c for engaging the base cover 23. The arm portion 21b is formed so that the rear is higher and the front is lower, so that rainwater and the like received on the upper surface is guided forward.
As shown in FIG. 8 , the base frame 20 is a substantially L-shaped member, and includes a substantially vertical vertical piece 26 and a horizontal piece 27 that protrudes forward from the vicinity of the lower end of the vertical piece 26 .

The vertical piece 26 is a plate-like part that is fixed in contact with the surface (wall surface 70) of the building structure. A mounting hole for passing the mounting bolt 20a is pre-drilled in the vertical piece 26, and the mounting bolt 20a is inserted into this hole and the mounting nut 20b is fastened from the front to fix it to the wall surface 70. At this time, the rear surface of the vertical piece 26 is fixed in a state where it is tightly attached to the surface of the building structure. Since there is no gap between the vertical piece 26 and the surface of the building structure, it is possible to prevent rainwater, etc. from entering the gap. A cover mounting piece 26d, a locking piece 26a, and a support piece 26b are formed on the front surface of the vertical piece 26 and protrude forward.

The cover mounting piece 26d is for attaching the upper end of the base cover 23 and is provided near the upper end of the vertical piece 26. The upper surface of this cover mounting piece 26d slopes downward as it moves forward.

The locking piece 26a is a portion that protrudes forward to lock the hook portion 21a of the base angle 21 described above. The locking piece 26a protrudes horizontally in an approximately J-shape and opens downward. The hook portion 21a can be hooked to the locking piece 26a. Specifically, with the base angle 21 tilted, the hook portion 21a can be inserted into the inside of the locking piece 26a from below, and the hook portion 21a can be hooked to the inside of the locking piece 26a. After that, when the base frame 20 is rotated around the hooked tip as an axis, the locking piece 26a can embrace and hold the hook portion 21a. Note that since the locking piece 26a only hooks and holds the hook portion 21a, it can be easily disengaged by tilting the base angle 21. The upper surface of the locking piece 26a is inclined downward as it goes forward, so that rainwater and the like can be guided forward.

The support piece 26b is a portion that protrudes so that the rear end 11a of the eaves plate 11 can be abutted against it. A positioning protrusion 26c is formed at the tip of this support piece 26b, against which the rear end 11a of the eaves plate 11 can be abutted. When the eaves material 12 is attached to the base frame 20, the rear end 11a of the eaves plate 11 can be abutted against the positioning protrusion 26c to align the position of the eaves material 12. In addition, this positioning protrusion 26c protrudes vertically above the gutter groove 27c described later. Therefore, when the eaves material 12 is attached at a position where it abuts against the positioning protrusion 26c, the lower end 11b of the rear end 11a of the eaves plate 11 (eaves material 12) is positioned inside the gutter groove 27c. In other words, a gap is formed between the lower end 11b of the rear end 11a of the eaves plate 11 and the gutter groove 27c by the positioning protrusion 26c supporting the rear end 11a of the eaves plate 11. This arrangement allows water that accumulates in the intermediate gutter section 54 and the secondary gutter section 64 to flow smoothly into the gutter groove 27c. The upper surface of the support piece 26b is inclined downward toward the front, so that rainwater and the like are guided forward.

The horizontal piece 27 is a part that protrudes forward from the vertical piece 26 and supports the underside of the eaves plate 11. The horizontal piece 27 in this embodiment has a support surface 27g that supports the underside of the eaves plate 11 so that it slopes upward as it goes forward. This support surface 27g is a flat surface that forms an acute angle with the rear surface of the vertical piece 26 (the surface that contacts the wall surface 70), and the eaves plate 11 is placed on this support surface 27g, resulting in a so-called reverse slope of the eaves. In a building eaves 10 with such a reverse slope, rainwater received by the building eaves 10 flows toward the building structure.

The upper surface of the horizontal piece 27 is formed with a gutter groove 27c as shown in FIG. 8. The gutter groove 27c is located behind the support surface 27g. The gutter groove 27c is formed at the rear end 11a of the eaves plate 11 and can receive water that has flowed inside the eaves plate 11 (intermediate gutter section 54 and secondary gutter section 64). As shown in FIG. 9, the gutter groove 27c according to this embodiment is formed with a gutter front wall 27a on the front side and a gutter rear wall 27b on the rear side. The gutter rear wall 27b also functions as a reinforcement that supports the support piece 26b from below. The bottom surface of the gutter groove 27c is inclined forward, and a drain hole 27d is formed on the front side of the bottom surface (near the boundary with the gutter front wall 27a). The water collected in the gutter groove 27c is discharged downward (horizontal gutter 36) through the drain hole 27d. In addition, a protrusion 27h that protrudes downward is formed on the lower surface of the horizontal piece 27 behind the gutter groove 27c. By providing this protrusion 27h, even if water tries to flow from the opening edge of the drain hole 27d along the underside of the horizontal piece 27 toward the vertical piece 26, the water is cut off by the protrusion 27h and falls into the horizontal gutter 36.

A gutter locking portion 27e that engages with the rear end of the gutter 36 protrudes from the underside of the horizontal piece 27. The gutter locking portion 27e in this embodiment protrudes downward from the vertically lower portion of the vertical piece 26. The gutter locking portion 27e is formed in a generally horizontal L-shape, with the tip protruding forward.

A bracket engagement portion 27f is provided at the front end of the horizontal piece 27 for connecting the horizontal gutter bracket 35. The horizontal gutter bracket 35 is a plate-shaped member that is provided to extend the horizontal piece 27 of the base frame 20. This horizontal gutter bracket 35 is formed to be shorter than the base frame 20, and multiple horizontal gutter brackets 35 are attached at intervals in the width direction W. This interval is used to position the drain portion 31, so that the horizontal gutter bracket 35 and the drain portion 31 do not interfere with each other.

As shown in Fig. 9, the gutter bracket 35 according to this embodiment comprises a flat plate portion 35a, a rear end engagement portion 35b provided at the rear end of the flat plate portion 35a, an engagement recess 35c provided at the front end of the flat plate portion 35a, and a gutter support piece 35d extending diagonally downward and rearward from the engagement recess 35c. As shown in Fig. 8, this gutter bracket 35 is attached to the eaves plate 11 with a fixing device such as a screw by abutting the flat plate portion 35a against the underside of the eaves plate 11 with the rear end engagement portion 35b engaged with the bracket engagement portion 27f. The engagement portion 27f also serves as a screw hole for screwing the gutter cover 37 attached to both sides of the gutter 36.

A horizontal gutter 36 is attached to the horizontal gutter engaging portion 27e and the gutter support piece 35d. This horizontal gutter 36 can collect and drain water discharged from the gutter groove 27c and the drain portion 31. In addition, as shown in FIG. 6, a notch 12b is formed on the underside of the eaves material 12 to cut off water adhering to the joint between adjacent eaves materials 12. This notch 12b is for cutting off the edge of water droplets adhering to the joint of the eaves material 12, and is formed in a position covered by the horizontal gutter 36. By providing this notch 12b, even if water droplets adhering to the joint of the eaves material 12 try to rise toward the tip (forward direction) of the eaves material 12 due to capillary action, the water is cut off by the notch 12b, and the cut off water evaporates or falls into the horizontal gutter 36.

The building eaves 10 described above can be attached to the wall surface 70, for example, by the following procedure. Although not specifically explained in the procedure below, appropriate sealing is performed to ensure watertightness of gutters, etc.

(1) The mounting bolt 20a is attached to the wall surface 70. For example, a base material is attached to the back side of the wall surface 70, and the mounting bolt 20a inserted from the back side is fixed to the base material. This causes the mounting bolt 20a to protrude from the wall surface 70. Note that the mounting bolt 20a does not have to be attached in advance, and it can be inserted into the wall surface 70 from the side where the base frame 20 is attached, sandwiching the base frame 20, and fixed with the mounting nut 20b on the indoor side of the wall surface 70.

(2) Attach the base frame 20. Specifically, insert the mounting bolts 20a into the holes pre-formed in the base frame 20, and tighten the mounting nuts 20b from the front.

(3) Attach the eaves material 12 at the end (either the left eaves material 14 or the right eaves material 15). Specifically, the eaves material 12 is placed on the horizontal piece 27 of the base frame 20 and sandwiched from above by the base angle 21, and the base angle 21, eaves material 12, and base frame 20 are fixed together with the eaves fixing device 22. As shown in Figure 8, the eaves fixing device 22 in this embodiment is a bolt and nut that penetrates the mounting portion 21c of the base angle 21, the eaves material 12, and the horizontal piece 27 of the base frame 20, and this eaves fixing device 22 can fix these three components together.

(4) The remaining eaves materials 12 are attached in order. That is, adjacent eaves materials 12 are joined using the procedure described in FIG. 4 or FIG. 5. Then, as shown in FIG. 6, the joined eaves materials 12 are slid all the way to the back of the base frame 20. Then, they are clamped from above with the base angle 21 and fixed with the eaves fixing device 22. At this time, if the eaves materials 12 have mounting holes 12c formed, the drain section 31 is attached to the mounting holes 12c.

(5) Once all of the eaves materials 12 have been installed, screw the tip frame 28 to the tip of the eaves plate 11, and then screw the tip cover 29 to the tip frame 28.

(6) The base cover 23 is attached to the top of the base frame 20. Specifically, first, the front end of the base cover 23 is hooked onto the cover engagement portion 21d provided at the front end of the base angle 21. Then, the rear end of the base cover 23 is placed on the cover attachment piece 26d of the base frame 20 and fixed with the base cover screws 24.
(7) The base lid 25 is fixed to both sides of the base frame 20 with screws. Also, the tip lid 30 is fixed to both sides of the tip cover 29 with screws.

(8) The gutter bracket 35 is screwed to the underside of the eaves plate 11. Then, the gutter 36 is screwed. The gutter cover 38 is attached to the location where the gutter 36 is screwed.
(9) The gutter cover 37 is attached to both sides of the gutter 36 with screws.
(10) Connect the downspout 39 to the horizontal gutter 36. This completes the installation.
As shown in FIG. 10 , the drain portion 31 according to this embodiment is configured to include a drainage member 32 and a drain cover member 33 .

The drainage member 32 is a member that is inserted into the mounting hole 12c formed in the eaves material 12. The drainage member 32 is formed of a rear wall 32a and a pair of side walls 32b that extend forward from both ends of the rear wall 32a, forming an approximately U-shaped shape in plan view. In addition, the upper end of the pair of side walls 32b is provided with a bent portion 32c that extends in a direction perpendicular to the side walls 32b. The rear wall 32a and the pair of side walls 32b are shaped to fit closely to the inner circumferential surface of the mounting hole 12c. The front end of the mounting hole 12c is provided with a positioning shape 12d that engages with the front end of the side walls 32b. For this reason, the drainage member 32 is formed so that it cannot be attached in a different orientation (for example, an orientation in which the rear wall 32a is in the front) because the rear wall 32a interferes. When the drainage member 32 is inserted into the mounting hole 12c, the bent portion 32c comes into contact with the upper surface of the eaves material 12.

The drain cover member 33 is a member that is attached above the drain member 32 so as to cover the drain member 32. The drain cover member 33 has a hole 33a for introducing water into the drain member 32. The drain cover member 33 that is layered on the drain member 32 is fixed to the upper surface of the eaves material 12 by a screw 33b. The screw 33b penetrates the drain cover member 33, the bent portion 32c, and the upper surface (upper plate portion 40) of the eaves material 12 in one go and is attached. The hole 33a is sized so that things other than water, such as fallen leaves, do not easily get in. The shape and size of the hole 33a may be easily changed depending on the application. For example, multiple types of drain cover members 33 (not shown) with different hole shapes and sizes may be manufactured in advance, and the optimal drain cover member 33 may be selected depending on the application and attached to the drain member 32. In this way, the same drain member 32 can be used even when the application is different, so the number of parts is reduced. As shown in FIG. 8, the drain portion 31 protrudes from the underside (lower plate portion 41) of the eaves material 12, so that water that has infiltrated inside the eaves material 12 is reliably drained downward. In addition, the drain portion 31 in this embodiment is composed of a drainage member 32 and a drain cover member 33, but this is not limited, and the drainage member and the drain cover member may be integrated.

As described above, the eaves plate 11 has side end gutter sections 68 on both sides. Specifically, as shown in FIG. 11, the side end gutter sections 68 are formed at the left end of the left end eaves material 12 (left eaves material 14) and the right end of the right end eaves material 12 (right eaves material 15). As shown in FIG. 12, the side end gutter section 68 opens upward in a roughly U-shape. In addition, as shown in FIG. 11 and FIG. 12, a plurality of elongated drainage holes 68a are formed near the rear end of the side end gutter section 68. The drainage holes 68a are for draining water flowing through the side end gutter section 68 to the horizontal gutter 36 below. As shown in FIG. 12, the side end gutter section 68 has an inside corner section 68b (inner corner section) formed in an R shape, and among the above-mentioned plurality of drainage holes 68a, the drainage holes 68a provided at both ends are formed to overlap the inside corner section 68b. Inside the side end gutter 68, a blocking material 68c is provided to block the rear end of the side end gutter 68. As shown in FIG. 13, the blocking material 68c has an abutment 68d adjacent to the rear end of the drainage hole 68a. The presence of this abutment 68d makes it possible to prevent water from flowing into the side end gutter 68 behind the drainage hole 68a.

Next, the gutter 36 according to this embodiment will be described in detail. As shown in FIG. 14(a), the gutter 36 according to this embodiment is a generally U-shaped member that opens upward, and includes a bottom surface portion 45, a front surface portion 46 that extends diagonally upward and forward from the front end of the bottom surface portion 45, and a back surface portion 47 that extends diagonally upward and backward from the rear end of the bottom surface portion 45.

Near the upper end of the surface portion 46, there is a recess 46a that is recessed toward the rear. This recess 46a is used to attach the gutter 36 to the gutter bracket 35. At the back of this recess 46a (the bottom edge recessed toward the rear), there is an attachment surface 46b that abuts from the front against the gutter support piece 35d of the gutter bracket 35. A protrusion 46d for hanging the gutter cover 38 is formed on the front surface of this attachment surface 46b. At the front end of the upper edge of this recess 46a, there is a rotation receiver 46e that can rotatably hang the gutter cover 38. In addition, an insertion piece 46f is formed to protrude rearward from the upper end of the surface portion 46.

A first protruding piece 47a that protrudes rearward is provided at the upper end of the back surface portion 47. A second protruding piece 47b that protrudes rearward is provided below the first protruding piece 47a. A vertical piece 47c that extends downward is provided at the tip of the second protruding piece 47b. An insertion groove portion 47d is formed between the first protruding piece 47a and the second protruding piece 47b.

As shown in FIG. 15(a), the gutter 36 can be slid from front to rear to engage with the base frame 20 (and the gutter bracket 35). That is, the gutter 36 can be temporarily fixed to the base frame 20 by inserting the insertion piece 46f on the front side into the engagement recess 35c of the gutter bracket 35 and the first protruding piece 47a on the back side into the inside of the gutter locking piece 27e of the base frame 20. At this time, as shown in FIG. 15(b), the gutter locking piece 27e is inserted into the insertion groove 47d. The vertical piece 47c also abuts against the wall surface 70. The mounting surface 46b also abuts against the gutter support piece 35d.

To ensure that the gutter 36 is inserted all the way to the back (rear), the vertical piece 47c at the rear end of the gutter 36 can be pushed backwards and pressed against the exterior wall 70. That is, by inserting a hand into the space in front of the vertical piece 47c and pushing the vertical piece 47c backwards, the gutter 36 can be reliably slid to the specified installation position.

After sliding the gutter 36 to the specified position in this way and temporarily attaching it to the base frame 20, the gutter 36 is fixed in place by attaching a fastener 46c such as a screw from the front of the mounting surface 46b. At this time, the mounting surface 46b of the fastener 46c is inclined so that it faces diagonally downward. Therefore, the underside of the lower plate portion 41 of the eaves plate 11 and the mounting surface 46b of the fastener 46c form an obtuse angle, ensuring a wide working space between the two.

After the fastener 46c is attached as described above, the gutter cover 38 is attached so as to cover the mounting surface 46b. The gutter cover 38 according to this embodiment can be attached to the gutter 36 simply by fitting it together, without using screws or the like. When the gutter cover 38 is attached to the gutter 36, the recess 46a is blocked, hiding the fastener 46c and making the surface of the gutter 36 appear flush.

As shown in FIG. 14(b), the gutter cover 38 has a decorative surface portion 38a, a pivoting engagement portion 38b, and an engagement leg portion 38c. The decorative surface portion 38a is formed so as to be flush with the surface of the gutter 36. The pivoting engagement portion 38b is formed so as to protrude upward in an arc shape from the upper end of the decorative surface portion 38a. The engagement leg portion 38c is formed so as to protrude rearward from the back surface of the decorative surface portion 38a.

When attaching this gutter cover 38 to the gutter 36, first, as shown in FIG. 16(a), the pivot engagement portion 38b at the upper end is inserted into the pivot receiving portion 46e to engage it. Then, as shown in FIG. 16(b), the lower end is rotated around the pivot engagement portion 38b, and the gutter cover 38 is fitted into the recess 46a. Then, the engagement leg 38c engages with the protrusion 46d, and the gutter cover 38 is fixed in place.

As shown in FIG. 17, the above-mentioned horizontal gutter 36 is formed by joining multiple gutter members 36a. The multiple gutter members 36a are connected via an inner joint material 48 and an outer joint material 49 that are attached so as to sandwich the joint portion 36b. As shown in FIG. 18, the inner joint material 48 is attached so as to cover the joint portion 36b where the multiple gutter members 36a are joined from above. The outer joint material 49 is attached so as to cover the joint portion 36b where the multiple gutter members 36a are joined from below. The inner joint material 48 can be fixed by simply fitting it inside the horizontal gutter 36 without fixing it with screws or the like. The outer joint material 49 can be fixed to the horizontal gutter 36 by a joint screw 49a or the like. At this time, if the joint screw 49a is attached from the outside of the horizontal gutter cover 38 using the recess 46a, the outer joint material 49 can be attached without drilling a hole in the horizontal gutter 36. Since no holes are drilled in the gutter 36, water leakage from the gutter 36 can be prevented.

The width (length) of the horizontal gutter 36 is desirably greater than the width of the base frame 20. Furthermore, the width of the horizontal gutter 36 is desirably greater than the width of the base frame 20 with the base lid 25 attached. In other words, as shown in FIG. 19, it is desirably arranged so that the base frame 20 and the base lid 25 fit inside the horizontal gutter 36 when viewed from above. By ensuring a sufficient width for the horizontal gutter 36 in this way, water can be reliably received even if it drips from the base frame 20.

As described above, according to the building eaves 10 of this embodiment, the gutter 36 can be slid from front to rear to engage with the base frame 20, so that installation and replacement of the gutter 36 can be easily performed by one person. In other words, when installing the gutter 36, the gutter 36 can be temporarily secured by sliding it from front to rear, making installation easy. In addition, when removing the gutter 36, the fastener 46c can be removed and the gutter 36 can be slid forward, so that only the gutter 36 can be easily replaced.

The gutter 36 is fixed by attaching the fastener 46c from the front, and the mounting surface 46b of the fastener 46c provided on the gutter 36 is inclined so that it faces diagonally downward. With this configuration, tools, etc. are less likely to interfere with the eaves plate 11 when attaching the fastener 46c, making the work easier.

In addition, the gutter cover 38 is provided to cover the mounting surface 46b, and the gutter cover 38 can be attached to the gutter 36 by hooking the upper end and rotating the lower end. With this configuration, the cover can be attached to the mounting surface 46b with a simple operation.
Furthermore, since the width of the horizontal gutter 36 is greater than the width of the base frame 20, water dripping from the base frame 20 can be reliably received.

The horizontal gutter 36 is made up of multiple gutter members 36a, which are connected via an inner joint material 48 and an outer joint material 49 that are attached so as to sandwich the joint portion 36b. This configuration allows the horizontal gutter 36 to be easily made to any length. Also, by sandwiching it between the inner and outer joint materials 48, 49, it is possible to reliably prevent water leakage from the joint portion 36b.
