Description

Technical Field

[0001] The present invention relates to an eaves support member that can be applied to various roofs such as ordinary houses and apartment houses, and can stably and reliably attach various eaves gutters to the eaves of the roof, and a repair structure for the eaves of a building using the same.

Background Art

[0002] Conventionally, a roof with a rain gutter in which a gutter is attached to the eaves of the roof is known. For example, as disclosed in Patent Document 1, a roof with a rain gutter is known in which a mounting base is attached to an eaves constituent member of the roof, a support arm is rotatably attached to the mounting base, and a gutter is attached to the support arm.

Problems to be Solved by the Invention

[0004] In the roof with a rain gutter described in Patent Document 1, since the support arm can be rotated with respect to the mounting base, the gutter can be horizontally attached by rotating the support arm according to the gradient of the eaves constituent member, that is, the roof gradient. In short, it can cope with differences in roof gradients.

[0005] However, the roof with a rain gutter described in Patent Document 1 includes three types of members: a mounting base, a support arm, and a gutter, and the mounting base and the support arm are short, and a plurality of mounting bases are attached at intervals in the longitudinal direction of the eaves constituent member, so a plurality of mounting bases and support arms are used respectively. Moreover, because the mounting base and support arms are either short pieces formed by bonding together a wide variety of small parts, or extremely complex molded items, their design and manufacturing costs are high, and since the eaves gutter is attached across multiple support arms, the roof eaves components are visible when a person visually inspects the roof. For this reason, in conventional roofs with rain gutters, the eaves components must be of superior aesthetic design to improve the appearance of the eaves, which results in high costs.

[0006] Therefore, the present invention provides an eaves support material that can be applied to various types of roofs, such as those of ordinary houses and apartment buildings, and that allows various types of gutters to be attached to the eaves of the roof, as well as a building eaves repair structure using the same. [Means for solving the problem]

[0007] The present invention has been proposed in view of the above, and is a member for attaching a gutter, having the same cross-sectional shape in the longitudinal direction, a fixed part to which a cover material that covers the open upper surface of the gutter, which is arranged on the eaves side of a building is fixed, an attachment part that is fixed to a vertical fascia wall surface, and the lower end of the side of the gutter on the building side From the outside The lower holding portion that is held is formed to extend in the longitudinal direction. It is a molded body made of a single component. This invention proposes an eaves support material characterized by the following features.

[0008] Furthermore, the present invention relates to an upper holding portion in the eaves support material that holds the upper end of the side of the gutter facing the building. but Preparation Rare We also propose an eaves support material characterized by [specific feature].

[0009] Furthermore, the present invention relates to a half eaves support material It is fixed to the fascia wall. This also proposes a renovation structure for the eaves of buildings, characterized by the following features. [Effects of the Invention]

[0010] The eaves support member of the present invention is a member for attaching a gutter and has the same cross-sectional shape in the longitudinal direction. It is a molded body consisting of a single component,The cover material that covers the open upper surface of the gutter installed on the eaves side of the building is fixed to the fixing part, the mounting part that is fixed to the vertical fascia wall surface, and the lower end of the side of the gutter on the building side From the outside Since the lower holding portion that is held is formed to extend in the longitudinal direction, the eaves gutter can be easily, reliably, and firmly attached. Furthermore, since this eaves support material can be installed without being affected by the construction of the roof structure, it can be applied to new or existing roofs, and in particular it can be easily used for the renovation of existing roofs, making renovation work easier. In addition, the eaves support material has the same cross-sectional shape in the longitudinal direction. It is a molded body made of a single component. Therefore, the design and manufacturing costs can be reduced, and the eaves gutter is fixed to both sides, i.e., the building side and the eaves end side, at the fixed part and the lower holding part. outside Therefore, it can be held stably.

[0011] Also, the side of the gutter facing the building top end Hold Upward The eaves support material equipped with a retaining part is This makes it easy to install the eaves gutter on the side facing the building. .

[0012] Furthermore, the eaves support material of the present invention It is fixed to the fascia wall. The building eaves renovation structure can be applied to various eaves structures of existing general houses, apartment buildings, and other buildings, allowing for the easy and reliable installation of various types of gutters as the existing eaves structures of buildings deteriorate.

Mode for Carrying Out the Invention

[0014] The eaves support member of the present invention is a member for attaching an eaves gutter, has the same cross-sectional shape in the length direction, and has a fixed portion to which a cover material covering the open upper surface of the eaves gutter disposed on the eaves side of the building is fixed, an attachment portion fixed to a vertical nose hiding wall surface, and the lower end of the side surface of the eaves gutter on the building side From the outside is held by a lower holding portion, and each of them is formed to extend in the length direction It is a molded body made of a single component. This is the gist.

[0015] The eaves gutter used in the eaves structure of the present invention is not limited in its material, dimensions, particularly the shape of the bottom surface and both side surfaces, etc., as long as a drainage channel for rainwater or the like is provided inside, but it is desirable that a supported portion (for example, in a corner shape or angled shape) for supporting this eaves gutter from below is formed at the lower part (lower end) of the side surface on the building side. And a cover material is attached so as to cover the open upper surface of this eaves gutter.

[0016] The cover material is attached by engaging its eaves end with the eaves end of the gutter and covers the open upper surface of the gutter. As shown in the illustrated embodiment described later, it is desirable to provide a substantially U-shaped engaging portion at its eaves end that is bent downward and inward, so that the eaves end of the gutter can engage with its back side. This substantially U-shaped engaging portion holds the eaves end of the gutter in a way that pulls it toward the building, so the cover material acts as an arm that holds the load of the gutter. Furthermore, as this cover material is a member that covers the open upper surface of the gutter as described above, it also prevents snow from accumulating inside, leaves from entering and accumulating, and birds from building nests inside. It also has water inlets on its surface, such as small-diameter slit holes, that guide rainwater into the gutter. Thus, the cover material is a member that is installed for the purpose of performing the above-mentioned effective functions. Therefore, the eaves support material of the present invention, which is fixed to this cover material, plays the role of holding (supporting) the gutter together with the cover material (= supporting the gutter through the cover material).

[0017] The eaves support material of the present invention includes a fixing portion for fixing the cover material, but the configuration of this fixing portion and the configuration of the fixing portion provided on the building-side end of the cover material are not particularly limited. For example, as shown in the illustrated embodiment described later, they may be formed in a flat shape, and the fixing portion of the cover material may be placed on the fixing portion of the eaves support material and fixed with screws or the like.

[0018] Furthermore, the eaves to which this eaves support material is attached can be any part that is composed of a "surface" when viewed from the eaves and to which fasteners such as screws can be tightened, and mainly refers to "eaves boards" and "fascia boards," but is not limited to these. Also, fascia boards, etc., can be vertical or inclined surfaces. In other words, in the eaves support material of the present invention, the attachment portion to be attached to the eaves can be appropriately set according to the shape of the part of the eaves, for example, it may be one location as shown in the illustrated embodiment 1 and reference example 1 later, or it may be two locations as shown in the illustrated embodiment 2 and reference example 2 later.

[0019] Furthermore, the eaves support material of the present invention is formed from a single component, as shown in the illustrated examples 1 and 2 described later, and is not formed from multiple components, as shown in the illustrated reference examples 1 and 2 described later. As described above, the eaves support material of the present invention may have one or more mounting points, and may be formed from a single member or from multiple members. For example, illustrated embodiment 1 and illustrated embodiment 2, described later, are similar in that they are formed from a single member, but embodiment 1 has one mounting point, and embodiment 2 has two mounting points. Also, illustrated reference example 1 and illustrated reference example 2, described later, are similar in that they are formed from multiple members, but reference example 1 has one mounting point, and reference example 2 has two mounting points.

[0020] For example, if the system consists of a main body having a part to which a cover material is fixed, a separate component (eaves mounting component) having a mounting part, and an (angle) adjustment mechanism to which one end of these components is pivotally attached (see illustrated example 1 described later), then even if the eaves, such as a fascia board, has an inclined surface, the mounting part can be adjusted to an arbitrary fixed angle and integrated in contact with it, allowing for more stable and reliable fixing. Furthermore, in the case where the main body has a fixed portion for the cover material, and the eaves mounting material having a mounting portion is assembled to the main body in a slidable (protruding) adjustment mechanism (see illustrated example 2 described later), for example, even if the eaves have an inclined surface such as a fascia board, the mounting portion can be adjusted to an arbitrary protruding length and integrated in contact with it, and similarly it can be fixed more stably and securely. In other words, if the main body, which has a fixed portion for the cover material, is equipped with a position adjustment mechanism that allows the eaves mounting material, which has a mounting portion, to be assembled and integrated in a rotatable or slidable manner, then even if the eaves to which it is attached, such as a fascia board, is sloped, it can be fixed more stably and securely.

[0021] If the eaves support material of the present invention is equipped with the position adjustment mechanism described above, a fixing means is required to integrate the two members. This fixing means may be, for example, a fastener such as a screw, and is not particularly limited. In particular, when a configuration is adopted in which the other ends of both members are fitted together with a cylindrical device (Illustrated Reference Example 1, described later), it is easier to install than, for example, a work using a fastener such as a screw that requires tightening. Also, when a configuration is adopted in which the two members are integrated with a fastener (Illustrated Reference Example 2, described later), it is easier to install than a work using a separate fastener such as a screw.

[0022] Furthermore, the eaves support material is located on the building-side side of the eaves gutter. Lower retaining part that holds the lower end hold downward Equipped with a holding part Therefore, in combination with the configuration of the fixed part that secures the cover material, the gutter can be stably held from both sides, that is, from the building side and the eaves end side. Furthermore, it is equipped with an upper retaining part that holds the upper end of the side of the gutter facing the building. In this case, the installation of the eaves gutter can be made more stable. 。

[0023] Furthermore, the building eaves repair structure using the eaves support material of the present invention can be applied to various eaves structures of existing general houses, apartment buildings, and other buildings, allowing for the easy and reliable installation of various types of gutters as the eaves structure of existing buildings deteriorates. [Examples]

[0024] The eaves support member 1 of Embodiment 1 shown in Figures 1(a) and 1(b) comprises a fixing portion 11 for fixing a cover material 3 that covers the open upper surface of the eaves gutter 2, and a mounting portion 12 that is attached to the eaves (a substantially vertical wall surface is the fascia wall surface 4A). The eaves support member 1 of this embodiment 1 is a molded body (piece material) made of a single member, and has a portion where a vertical piece 13 arranged substantially vertically and a horizontal piece 14 arranged substantially horizontally intersect. The fixed portion 11 is provided at the eaves-side end of the horizontal piece 14, and the mounting portion 12 is formed as a vertical surface that protrudes substantially in a U-shape toward the building from a vertical piece 17 extending downward from the vertical piece 13. This mounting portion 12 is arranged so as to protrude toward the building from the vertical piece 13 with an upper piece 10o and a lower piece 10u facing each other vertically, and mounting holes 121 for driving in a fastener (1c) are formed at two locations, upper and lower.

[0025] In this embodiment 1, the eaves support member 1 has holding parts (15, 161) that hold the upper and lower ends of the building-side side 23 of the eaves gutter 2, in addition to the fixed part 11 and the mounting part 12. Specifically, a roughly L-shaped lower holding portion 15 is extended from the lower piece 10u towards the eaves, and as shown in Figure 1(c), the lower holding portion 15 holds (supports) the lower end (held portion 231) of the side surface 23 of the gutter 2. Furthermore, a groove-shaped upper holding portion 161, which is open at the bottom, is formed between the inclined piece 16 extending toward the eaves side from the intersection of the vertical piece 13 and the horizontal piece 14 and the vertical piece 17. As shown in Figure 1(c), the upper holding portion 161 holds (engages) the upper end 232 of the side surface 23 of the gutter 2. Note that the parts indicated by reference numerals 18 and 19 in the figure do not play any particular role in this embodiment 1 and will therefore not be described.

[0026] The eaves structure shown in Figure 1(c) is an example using the eaves support material 1 of Embodiment 1, in which the gutter 2 has a stepped side surface 22 formed on the eaves side (left side in the drawing) of the substantially horizontal bottom surface 21, which is composed of three inclined surfaces and two substantially horizontal surfaces, and a substantially vertical side surface 23 is formed on the building side of the bottom surface 21, and a drainage channel for rainwater and the like is formed by these bottom surface 21 and side surfaces 22, 23. The inclined surface and the substantially horizontal surface located at the upper end of the side surface 22 on the eaves side are the eaves tip 221 which is held (engaged) by the engaging portion 32 of the cover material 3. Furthermore, a corner-shaped holding portion 231 is provided at the lower end of the side surface 23, and this portion is positioned and held from above on the substantially L-shaped lower holding portion 15 of the eaves support member 1. The upper end 232 of this side surface 23 is positioned and held from below on the upper holding portion 161 of the eaves support member 1 by insertion.

[0027] Furthermore, the cover material 3 in this eaves structure is a component that prevents snow from accumulating inside, leaves from entering and accumulating, and birds from building nests. Multiple small-diameter slit holes are formed on its surface (decorative surface 31) as water inlets 311 to guide rainwater inside. An engaging portion 32, formed in a roughly U shape, is attached to the eaves tip by engaging with the eaves tip 221 of the gutter 2, and a fixing portion 33 is formed near its upper end to be fixed to the fixed portion 11 of the eaves support material 1. The upper end 34, which is folded up in a roughly vertical shape, is aligned with the vertical piece 13 of the eaves support material 1 and faces the back side of the flashing material 6b which is placed on the back side of the exterior material 6A. The engagement portion 32 extends diagonally upward from the eaves tip of the decorative surface 31, its tip is bent downward, and its lower end is further bent inward, forming a roughly U-shape. A drainage groove 35 is formed at the boundary between the decorative surface 31 and the engagement portion 32, and water inlets 351 are formed at predetermined intervals. The fixing portion 33 is located near the building-side end of the decorative surface 31, and in this embodiment 1, it is fixed to the fixing portion 11 of the eaves support material 1 with screws 1b.

[0028] As described above, the eaves to which the eaves support member 1 is attached are configured such that a substantially vertical wall surface forms a fascia wall surface 4A, and the mounting portion 12, which is a vertical surface, is placed along the wall surface 4A, and the fasteners 1c, 1c are driven in through two holes 121 in the mounting portion 12 to secure it. Furthermore, a vertical wall surface 4B is installed on the back side of wall surface 4A, and roof sheathing 4C and exterior cladding 6A are installed on the upper surface of the H-shaped frame 5 that forms the roof slope. Additionally, flashing materials 6b and 6c are fixed to the upper eaves side of roof sheathing 4C with fasteners 6d, and a waterproof sheet 6e is laid.

[0029] As described above, the eaves support member 1 of Embodiment 1 includes a fixing portion 11 for fixing a cover material 3 that covers the open upper surface of the eaves gutter 2 which is installed on the eaves side of the building, and a mounting portion 12 that is attached to the eaves (4A). Therefore, the eaves gutter 2 can be easily attached to the eaves (4A) such as a fascia board or a wide board. Furthermore, since this eaves support material 1 can be installed without being affected by the construction of the roof structure, it can be applied to new or existing roofs, and can be easily used in the renovation of existing roofs, making renovation work easier.

[0030] Furthermore, the eaves support member 1 of this embodiment 1 is equipped with holding parts (15, 161) that hold the upper end 232 and lower end (held part 231) of the side surface 13 on the building side of the eaves gutter 2. Combined with the configuration of the fixed part 11 that fixes the cover material 3, the eaves gutter 2 can be stably held from both sides, i.e., the building side and the eaves tip side.

[0031] The eaves support member 7 in Reference Example 1 shown in Figure 2(d) consists of a main body 7A having a fixed portion 11 for fixing a cover material 3 that covers the open upper surface of the eaves gutter 2, and an eaves mounting member 7B which is a separate component having an attachment portion 71. As shown in Figures 2(a) and 3(b), the main body 7A is the same as the eaves support member 1 in Embodiment 1, and all the part reference numerals are the same as in Embodiment 1, so the explanation of parts other than those indicated by reference numerals 18 and 19 will be omitted. Reference numeral 18 denotes a shaft portion formed in a small arc shape, and 19 denotes a locking projection portion which is a downward-facing piece. In reference example 1, the attachment portion of the eaves support member 7 to the eaves 4A', 4A'' is the attachment member 71 of the eaves attachment member 7B as described above, and the reference numeral for the attachment portion (12) in embodiment 1 has been deleted. As shown in Figures 2(b) and 3(a), the eaves mounting material 7B is a piece material having a rectangular vertical mounting portion 71 with holes 711, 711 for driving in fasteners 7d, a large arc-shaped bearing portion 72 into which the shaft portion 18 of the main body 7A is inserted at its upper end, and an arc-shaped locking receiving piece 73 at its lower end. Furthermore, multiple stages of engaging teeth 731 are formed on the upper surface side of the locking receiving piece 73, into which the locking projection 19 of the main body 7A abuts (locks). The cylindrical component 7C, which is used as a fixing means for the main body 7A and the eaves mounting material 7B, is a cylindrical body having a rectangular cavity and is a component that fits together the main body 7A and the eaves mounting material 7B to form a single unit.

[0032] In this reference example 1, first, as shown in Figures 2(c) and 3(d),(e), the shaft portion 18 of the main body 7A is inserted into the bearing portion 72 of the eaves mounting material 7B, and the lower end of the locking projection 19 is mounted so that it faces the engaging teeth 731. In this state, the eaves mounting material 7B can be rotated relative to the main body 7A with the shaft portion 18 and the bearing portion 72 as the central axis. Then, once the predetermined angle is set, the cylindrical member 7C is fitted onto both members 7A and 7B and integrated (fixed). Specifically, the upper and lower frames of the cylindrical member 7C are used to sandwich the lower piece 10u of the main body 7A and the locking receiving piece 73 of the eaves mounting material 7B, thereby integrating (fixing) them together.

[0033] The eaves structures shown in Figures 4(a) and 4(b) utilize the eaves support material 7 from Reference Example 1, and can be easily applied by adjusting the angle, whether the eaves structure in Figure 4(a) has a relatively gentle slope or the eaves structure in Figure 4(b) has a relatively steep slope. In these eaves structures, the structural elements and exterior materials used are exactly the same as those in Figure 1(c), but the angle of inclination is completely different from that in Figure 1(c). Therefore, the eaves (fascia wall surface) 4A, which was arranged almost vertically, are represented as 4A' in Figure 4(a) and 4A'' in Figure 4(b), with the same reference numerals used for other members and parts.

[0034] When constructing these eaves structures, as described above, one end of the main body 7A and the eaves mounting member 7B that constitute the eaves support member 7 are pivotally attached, and the lower end of the locking projection 19 of the main body 7A is attached so as to face the engaging teeth 731 of the eaves mounting member 7B. As described above, the mounting portion 71 of the eaves mounting member 7B is provided with holes 711, 711, so the mounting portion 71 is aligned with the respective fascia wall surface 4A, and the fasteners 7d are driven into the holes 711, 711 to secure it. Furthermore, for angle adjustment in each eaves structure, the lower end of the locking projection 19 is kept in contact with (locked to) the multiple stages of engaging teeth 731, while the vertical piece 13 of the main body 7A is rotated until it is positioned vertically. Subsequently, the cylindrical component 7C is fitted onto both members 7A and 7B to integrate (fix) them together.

[0035] Thus, the eaves support member 7 in Reference Example 1 allows for the installation of the eaves gutter 2 in almost the same manner using a single type of eaves support member 7, even for eaves with different slope gradients. Furthermore, the formed eaves structure has the exact same installation angle for the eaves gutter 2, as shown in Figures 4(a) and (b), and can be fixed stably and securely. Furthermore, in this reference example 1, since the cylindrical device 7C is used as a fixing means, there is no need for work such as tightening screws, resulting in excellent workability.

[0036] The eaves support member 8 of Embodiment 2 shown in Figure 5(a) comprises a fixing portion 81 for fixing a cover material 3 that covers the open upper surface of the eaves gutter 2, and a mounting portion 82 that is attached to the eaves (a substantially vertical wall surface is the fascia wall surface 4A). The eaves support member 8 of this embodiment 2 is a molded body (piece material) made of a single member, similar to the eaves support member 1 in embodiment 1, and is common in that it has a vertical piece 82 and a horizontal piece 84, but the upper end of the vertical piece 82 is curved toward the eaves, and its substantially vertical portion also serves as the upper mounting portion 82o. In addition, the fixed portion 81 provided at the eaves-side end of the horizontal piece 84 extends far toward the building, and the mounting portion consists of the upper mounting portion 82o and the lower mounting portion 82u, which is a vertical surface protruding toward the building from a vertical piece 87 that extends below the vertical piece 82. The lower mounting portion 82u has an inclined upper piece 80o positioned at its upper end so as to protrude toward the building, and a substantially horizontal lower piece 80u positioned at its lower end. Furthermore, fasteners (1c') are driven into the two mounting sections 82o and 82u at the top and bottom, with a circular hole 821 formed in the lower mounting section 82u and a vertically elongated hole 822 formed in the upper mounting section 82o.

[0037] In this embodiment 2, the eaves support member 8 has holding parts (85, 861) that hold the upper and lower ends of the building-side side 23 of the eaves gutter 2, in addition to the fixed part 81 and the mounting parts 82o, 82u. Specifically, a roughly L-shaped lower holding portion 85 is formed on the eaves side of the lower piece 80u, and as shown in Figure 5(b), the lower holding portion 85 holds (supports) the lower end (held portion 231) of the side surface 23 of the gutter 2. Furthermore, a groove-shaped upper holding portion 861, which is open at the bottom, is formed between the inclined piece 86 extending toward the eaves side from the intersection of the vertical piece 82 and the horizontal piece 84, and the vertical piece 87. As shown in Figure 1(c), the upper holding portion 861 holds (engages) the upper end 232 of the side surface 23 of the gutter 2. Note that the parts indicated by reference numerals 80s and 89 in the figure do not play any particular role in this embodiment 1 and will therefore not be explained.

[0038] The eaves structure shown in Figure 5(b) is an example using the eaves support material 8 of Embodiment 2, and the eaves gutter 2, cover material 3, and exterior structure used in this eaves structure are almost the same as those in Figure 1(c), so the same reference numerals are used and their explanation is omitted. The difference from the above-described embodiment 1 is that the eaves support member 8 is attached to the eaves 4D at two mounting points 82o and 82u, so it is installed stably. Also, since the hole for driving in one of the fasteners 1c' is a vertically elongated hole 822, the mounting position of the eaves support member 8 can be adjusted vertically. Furthermore, the gutter 2 (side 23) is held stably, but the fixing strength is further increased by screwing it to the eaves support member 8 (vertical piece 87) with screws (screw 2b). The upper end of the cover material 3 is folded back to the back side to form an engaging portion 36, which engages with the tip that extends from the fixed portion 81 toward the building side, thereby increasing the installation strength of the cover material 3. Another difference is that the curved upper end of the vertical piece 82 is positioned on the back side of the flashing material 6c.

[0039] Furthermore, the eaves support member 8 of this embodiment 2, like the eaves support member 1 of embodiment 1, includes a fixing portion 81 for fixing a cover material 3 that covers the open upper surface of the gutter 2 which is installed on the eaves side of the building, and mounting portions 82o, 82u that are attached to the eaves (4A). Therefore, the gutter 2 can be easily attached to the eaves (4A) such as a fascia board or soffit. Furthermore, since this eaves support material 8 can be installed without being affected by the construction of the roof structure, it can be applied to new or existing roofs, and can be easily used in the renovation of existing roofs, making renovation work easier.

[0040] Furthermore, the eaves support member 8 of this embodiment 2 also includes holding parts (85, 861) that hold the upper end 232 and lower end (held part 231) of the side surface 13 on the building side of the eaves gutter 2. Combined with the configuration of the fixed part 81 that fixes the cover material 3, the eaves gutter 2 can be stably held from both sides, i.e., the building side and the eaves tip side. In Figure 5(b), the dotted line labeled 5b indicates a part called a gable wrap that is fabricated on-site, 5c indicates its fasteners, and 5d indicates a newly installed flashing that is fabricated on-site.

[0041] The eaves support member 9 in Reference Example 2 shown in Figures 6(c) and (d) uses the eaves support member 8 from Embodiment 2 as the main body 9A, and consists of a separate component, the eaves mounting member 9B, and a fastener 9C. As shown in Figure 6(a), the reference numerals for all parts of the main body 9A are the same as in the previous embodiment 2, so the explanation of parts other than those indicated by reference numerals 80s and 89 will be omitted. The reference numeral 80s of the main body 9A is an open-topped fitting groove formed on the building side of the lower piece 80u, into which a nut 90 can be fitted and secured. Also, 89 is a set of multiple engaging teeth formed on its back side. In the above embodiment 2, the substantially vertical portion of the vertical piece 82 was the upper mounting portion 82o, but in this reference example 2, the curved portion near the upper end of the vertical piece 82 is the upper mounting portion 82o', and the lower mounting portion 91 is formed on the eaves mounting material 9B instead of the main body 9A, and the reference numeral for the lower mounting portion (82u) in the above embodiment 2 has been removed. As shown in Figure 6(b), the eaves mounting material 9B is a roughly L-shaped piece, with a vertically elongated hole 911 provided in the lower mounting portion 91, which is a curved vertical surface at the upper end, into which a fastener 9d is driven. Multiple rows of engaging teeth 93 are formed on the upper surface of the eaves tip of the horizontal piece 92. The horizontal piece 92 is also provided with a horizontally elongated hole 921 into which the fastener 9C moves. The fastener 9C is an upward-facing bolt that can be tightened from below onto the nut 90 which is fitted and fixed in the fitting groove 80s.

[0042] In this reference example 2, with the nut 90 pre-fitted and fixed into the fitting groove 80s of the main body 9A, the eaves mounting member 9B is positioned from below, the engaging teeth 93 of the eaves mounting member 9B are engaged with the engaging teeth 89 of the main body 9A, and the fastener 9C is positioned from below the lateral piece 92 and attached through the hole 921 of the lateral piece 92 to the nut 90 in the fitting groove 80s (without being tightly fastened). In this state, with the engaging teeth 89 and 93 positioned opposite each other, the eaves mounting member 9B can be assembled to slide (slide toward the building) relative to the main body 9A. Then, once the predetermined protrusion dimension is determined, the fastener 9C is used to integrate (fix) the two members 9A and 9B together. Specifically, by firmly tightening the fastener 9C, the engaging teeth 89 of the main body 9A and the engaging teeth 93 of the eaves mounting material 9B are engaged and integrated (fixed).

[0043] The eaves structures shown in Figures 7(a) and 7(b) utilize the eaves support member 9 of Reference Example 2, and can be easily applied by adjusting the angle of the protruding dimension, whether the eaves structure in Figure 7(a) has a relatively gentle slope or the eaves structure in Figure 7(b) has a relatively steep slope. In these eaves structures, the frame and exterior materials used are exactly the same as those in Figure 5(b), but the angle of inclination is completely different from that in Figure 5(b). Therefore, the eaves (fascia wall surface) 4D, which were arranged almost vertically, are represented as 4D' in Figure 7(a) and 4D'' in Figure 7(b), with the same reference numerals used for other members and parts.

[0044] When constructing these eaves structures, the eaves support members 9, which have been assembled in advance as described above, are attached to the eaves 4D', 4D''. The two mounting parts 82o', 91 on the top and bottom of the eaves support member 9 are formed in a curved shape, so that they can be securely brought into contact with the eaves 4D', 4D''. In addition, since vertically elongated circular holes 822, 911 are formed in both the upper mounting part 82c' and the lower mounting part 91, the fasteners 1c' can be adjusted vertically and then fixed in place when driving them in. Furthermore, to adjust the protruding dimensions of each eaves structure, the engaging teeth 89 and 93 are rotated until the vertical piece 82 of the main body 9A is positioned vertically, while maintaining the position of the engaging teeth 89 and 93 facing each other. Subsequently, the fastener 9C is firmly tightened to integrate (fix) both members 9A and 9B together.

[0045] Thus, the eaves support member 9 in the above-mentioned Reference Example 2 allows for the installation of the eaves gutter 2 in almost the same manner using a single type of eaves support member 7 for eaves 4D' and 4D'' with different slope gradients. Furthermore, the formed eaves structure has the exact same installation angle for the eaves gutter 2, as shown in Figures 7(a) and (b), and can be fixed stably and securely. Furthermore, in this reference example 2, since the fastener 9C is used as the fixing means, there is no need for work such as tightening screws, resulting in excellent workability.
