Description

Technical Field

[0001] The present invention relates to an eaves gutter support and an eaves gutter support structure.

Background Art

[0002] As a support for an eaves gutter disposed below the eaves tip of a folded-plate roof, a J-shaped eaves gutter support is known, which includes a support body attached to the eaves tip of the folded-plate roof and an eaves gutter receiving portion formed to extend from the support body to support the eaves gutter (see Patent Document 1).

[0003] This eaves gutter support includes a support body having a substantially U-shaped support recess to be fitted into the eaves tip end portion of the folded-plate roof, and a bolt for screwing into a bolt screw hole drilled in the upper piece of the support recess to tighten and fix the support body to the eaves tip end portion. Further, it includes a U-shaped receiving portion having a vertical piece extending downward from the support body and a horizontal piece and a locking piece attached via an adjustment bolt so as to extend from the lower portion of this vertical piece. Since these vertical piece, horizontal piece, and support piece are assembled in a U shape, the eaves gutter can be supported by these. The eaves gutter support described in Patent Document 1 has a configuration in which the eaves gutter is supported by a U-shaped receiving portion formed by a vertical piece, a horizontal piece, and a locking piece extending downward from the support body. Also, the locking piece is provided rotatably with respect to the horizontal piece via a slide pin, and is configured such that the eaves gutter can be temporarily installed on the horizontal piece when the locking piece is rotated downward.

Summary of the Invention

Problems to be Solved by the Invention

[0005] Figure 11 is an explanatory diagram showing a structure for joining metal gutters when supporting gutters using a general gutter support. Figure 11 shows a case where multiple gutter supports 100 are installed at the eaves, and an adjacent gutter 102 is joined to a gutter 101 that is temporarily supported by some of the gutter supports 100. Sealant 103 is applied to the inner surface of the end of the temporarily supported gutter 101, the end of the gutter 102 is overlapped and inserted from above onto the end of the gutter 101, and the overlapping portion is riveted to join the gutters together. Figure 12 shows the structure when a resin gutter is supported by a gutter support 100. In the case of a resin gutter 105, riveting is not applicable, so a U-shaped joint 107 with claws is provided between the end of the temporarily supported gutter 105 and the end of the gutter 106 to be joined. Adhesive 108 is applied to the inner surface of the joint 107, and the gutter 106 can be joined to the gutter 105 via the joint 107 with the adhesive 108.

[0006] As shown in Figure 12, when joining a gutter 106 to a resin gutter 105, it is necessary to lift the end of the gutter 106 diagonally relative to the end of the gutter 105 and fit it into the joint 107. If, for example, as shown in Figure 11, one attempts to join the gutter 106 by pushing it downwards from above, there is a risk of scraping off the adhesive 108. Therefore, it is necessary to lift the end of the gutter 106 once and then carefully fit it into the joint 107. However, the inner surface of the gutter support 100 is equipped with locking brackets that secure the edges of the gutter 106, and in some cases, these locking brackets may restrict the lifting operation of the gutter 106.

[0007] This invention has been made in view of the circumstances described above, and aims to provide a gutter support and gutter support structure that does not interfere when joining adjacent gutters during work at height, such as at the eaves, and when the end of the gutter is moved up and down along the gutter support and fitted into place. [Means for solving the problem]

[0008] To solve the aforementioned problems, the present invention proposes the following embodiments. "1" The gutter support according to this embodiment is a gutter support attached to the tip of the eaves board of a roof and supporting the gutter, comprising: a support body attached to the tip of the eaves board; a vertical piece extending from a part of the support body in a direction intersecting the support body; a horizontal piece extending from the tip of the vertical piece in a direction intersecting the vertical piece; a vertical locking piece extending from the tip of the horizontal piece toward the support body and rotatably supported with respect to the horizontal piece; an extension piece formed on the tip side of the vertical locking piece and attachable to the upper side of the support body by rotation of the vertical locking piece; and a mounting bolt detachably attached to the support body and passing through the support body, and having a gutter upper edge locking piece rotatably provided along the inner surface of the vertical piece or the inner surface of the vertical locking piece on at least one of the inner surfaces of the vertical piece and the vertical locking piece Furthermore, a configuration can be adopted in which at least one of the vertical piece and the vertical locking piece is made of a profile having a recessed groove on the inner surface and a protruding wall on the outer surface, the upper edge locking piece of the eaves gutter is inserted into the bottom of the recessed groove at its base end, and is rotatably attached around an axis by a shaft member that penetrates the base end and the bottom of the recessed groove.

[0009] With the aforementioned gutter support, if the support body is attached to the tip of the eaves board of the roof and the gutter is supported inside the gutter support, and if a gutter upper edge locking piece is provided inside the gutter support, the position of the gutter upper edge locking piece can be adjusted by rotating it to avoid interference with the gutter as much as possible. This allows for the smooth lifting and fitting of the gutter ends inside the gutter support when joining adjacent gutters. Therefore, it does not hinder the joining process between adjacent gutters, providing a gutter support with excellent joining workability.

[0011] If at least one of the vertical piece and the vertical locking piece is made of a profile having a groove on its inner surface, the structural strength of the vertical piece and the vertical locking piece can be increased, providing a gutter support that is resistant to twisting and bending even when supporting a gutter. Furthermore, by inserting the base end into the groove of the vertical piece or vertical locking piece, and providing a gutter upper edge support piece around the axis of the shaft member that penetrates the base end, the gutter upper edge support piece can be rotatably mounted on the inner surface of the vertical piece or the inner surface of the vertical locking piece. By rotating this gutter upper edge support piece, interference with the gutter can be avoided, and a gutter support device equipped with a gutter upper edge locking piece that does not interfere with the lifting and fitting operations of the gutter during the joining work of adjacent gutters can be provided.

[0012] "2" The gutter support device relating to this form is A gutter support that is attached to the tip of the eaves board of a roof and supports the gutter, comprising: a support body attached to the tip of the eaves board; a vertical piece extending from a part of the support body in a direction intersecting the support body; a horizontal piece extending from the tip of the vertical piece in a direction intersecting the vertical piece; a vertical locking piece extending from the tip of the horizontal piece toward the support body and rotatably supported with respect to the horizontal piece; an extension piece formed on the tip side of the vertical locking piece and attachable to the upper side of the support body by rotation of the vertical locking piece; and a mounting bolt that is detachably attached to the support body and penetrates the support body, and a gutter upper edge locking piece provided rotatably along the inner surface of the vertical piece or the inner surface of the vertical locking piece on at least one of the inner surfaces of the vertical piece and the vertical locking piece, At least one of the vertical piece and the vertical locking piece is made of a profile having a groove on the outer surface and a protruding wall on the inner surface, and the upper edge locking piece of the eaves gutter is attached so as to be rotatable around an axis by a shaft member that penetrates the base end and the protruding wall.

Furthermore, by providing a gutter upper edge support piece around the axis of a shaft member that penetrates the protruding wall of the vertical piece or the vertical locking piece, the gutter upper edge support piece can be rotatably mounted on the inner surface of the vertical piece or the inner surface of the vertical locking piece. By rotating this gutter upper edge support piece, interference with the gutter can be avoided, and a gutter support device equipped with a gutter upper edge locking piece that does not interfere with the lifting and fitting operations of the gutter during the joining work of adjacent gutters can be provided.

[0014] "3" Gutter support device related to this form The preceding item in "1" or "2" The base end of the gutter locking piece is made of a curved plate, and a configuration can be adopted in which the inner diameter and curvature of the curved plate are such that they allow rotation of the gutter upper edge locking piece.

[0015] By constructing the base end of the upper edge locking piece of the eaves gutter from a curved plate, a configuration can be adopted that does not hinder the rotation of the upper edge locking piece of the eaves gutter, regardless of whether the base end is located inside the groove or outside the protruding wall. For example, if the curved plate is placed inside the groove, the curved plate can rotate along the inner surface of the groove, so the upper edge support of the eaves gutter can rotate freely along the inner surface of the vertical piece or the inner surface of the vertical locking piece.

[0016] 「4」 In the gutter support according to this embodiment, the upper edge locking piece of the gutter can be configured to have a base end and an L-shaped locking portion provided on the tip side of the base end.

[0017] By providing an L-shaped locking portion on the upper edge locking piece of the eaves gutter, it is possible to provide an upper edge locking piece of the eaves gutter that can switch between a state in which the upper edge of the eaves gutter is locked by the locking portion through rotation of the upper edge locking piece of the eaves gutter, and a state in which interference with the eaves gutter can be avoided without the upper edge of the eaves gutter being supported by the locking portion.

[0018] 「5」 The gutter support structure in this embodiment is configured such that the gutter is supported by a gutter support attached to the tip of the eaves board of the roof, and the gutter support comprises a support body attached to the tip of the eaves board, a vertical piece extending from a part of the support body in a direction intersecting the support body, a horizontal piece extending from the tip of the vertical piece to the same side as the support body, a vertical locking piece extending from the tip of the horizontal piece toward the support body and rotatably supported relative to the horizontal piece, and a part formed on the tip side of the vertical locking piece, which allows the vertical locking piece to rotate The support member has an extension piece that can be attached to the upper side of the support member body, and a mounting bolt that is detachably attached to the support member body and passes through the support member body, and a gutter upper edge locking piece that is rotatably provided along the inner surface of the vertical piece or the inner surface of the vertical locking piece on at least one of the inner surfaces of the vertical piece and the vertical locking piece, the support member body is fixed to the tip of the eaves board, the gutter is supported surrounded by the support member body, the vertical piece, the horizontal piece, the vertical locking piece and the extension piece, and the upper edge of the gutter is locked by the gutter upper edge locking piece, At least one of the vertical piece and the vertical locking piece is made of a molded material having a groove on its inner surface, and the upper edge locking piece of the eaves gutter is attached so as to be rotatable around an axis by an axis member that penetrates the base end and the bottom.

[0019] In the case of the support structure by the above-mentioned eaves gutter support tool, when the support tool main body is attached to the tip end portion of the eaves board of the roof and the eaves gutter is supported inside the eaves gutter support tool, if an eaves gutter upper edge locking piece is provided inside the eaves gutter support tool, the position can be adjusted so that the eaves gutter upper edge locking piece can be rotated to avoid interference with the eaves gutter as much as possible. Thus, in order to join the end portions of adjacent eaves gutters, the operation of lifting or fitting the end portion of the eaves gutter inside the eaves gutter support tool can be carried out without trouble. Therefore, an eaves gutter support tool that does not hinder the joining operation of adjacent eaves gutters can be provided.

[0021] If at least one of the vertical piece and the vertical side locking piece is made of a profiled material having a concave groove on the inner surface side and a ridge wall on the outer surface side, the structural strength of the vertical piece and the vertical side locking piece can be increased, and an eaves gutter support structure using an eaves gutter support tool that is strong against twisting and bending even when supporting the eaves gutter can be provided. Further, by inserting the base end portion into the concave groove of the vertical piece or the vertical side locking piece and providing an eaves gutter upper edge support piece around the axis of a shaft member that penetrates the base end portion, the eaves gutter upper edge support piece can be provided rotatably on the inner surface side of the vertical piece or the inner surface side of the vertical side locking piece. By the rotation operation of this eaves gutter upper edge support piece, interference with the eaves gutter can be avoided, and an eaves gutter support structure provided with an eaves gutter upper edge locking piece that does not interfere with the lifting and fitting operations of the eaves gutter during the joining operation of adjacent eaves gutters can be provided.

[0022] 「6」 The eaves gutter support structure of this embodiment The gutter is supported by a gutter support attached to the tip of the eaves board of the roof, and the gutter support comprises a support body attached to the tip of the eaves board, a vertical piece extending from a part of the support body in a direction intersecting the support body, a horizontal piece extending from the tip of the vertical piece to the same side as the support body, a vertical locking piece extending from the tip of the horizontal piece toward the support body and rotatably supported relative to the horizontal piece, and a part formed on the tip side of the vertical locking piece, which allows the support to rotate when the vertical locking piece rotates. The main body has an extension piece that can be attached to the upper side, and a mounting bolt that is detachably attached to the support body and passes through the support body, and has a gutter upper edge locking piece that is rotatably provided along the inner surface of the vertical piece or the inner surface of the vertical locking piece on at least one of the inner surfaces of the vertical piece and the vertical locking piece, the support body is fixed to the tip of the eaves board, the gutter is supported surrounded by the support body, the vertical piece, the horizontal piece, the vertical locking piece and the extension piece, and the upper edge of the gutter is locked by the gutter upper edge locking piece, At least one of the vertical piece and the vertical side locking piece is made of a profiled material having a concave groove on the outer surface side and a ridge wall on the inner surface side, and the eaves gutter upper edge locking piece has its base end portion along the tip end surface of the ridge wall and is rotatably attached around the axis by a shaft member that penetrates the base end portion and the ridge wall Characterized by .

[0023] If at least one of the vertical piece and the vertical side locking piece is made of a profiled material having a concave groove on the outer surface side and a ridge wall on the inner surface side, the structural strength of the vertical piece and the vertical side locking piece can be increased, and an eaves gutter support structure provided with an eaves gutter support tool that is strong against twisting and bending even when supporting the eaves gutter can be provided. Furthermore, by providing a gutter upper edge support piece around the axis of a shaft member that penetrates the protruding wall of the vertical piece or the vertical locking piece, the gutter upper edge support piece can be rotatably mounted on the inner surface of the vertical piece or the inner surface of the vertical locking piece. This rotational operation of the gutter upper edge support piece avoids interference with the gutter, and provides a gutter support structure equipped with a gutter upper edge locking piece that does not interfere with the lifting and fitting operations of the gutter when joining adjacent gutters.

[0024] "7" Main type of gutter support structure The preceding item described in "5" or "6" The base end is made of a curved plate, and the inner diameter and curvature of the curved plate are such that they allow the upper edge locking piece of the gutter to rotate.

[0025] By constructing the base end of the upper edge locking piece of the eaves gutter from a curved plate, a configuration can be achieved that does not hinder the rotation of the upper edge locking piece of the eaves gutter, regardless of whether the base end is located inside the groove or outside the protruding wall. For example, if the curved plate is placed inside the groove, the curved plate can rotate along the inner surface of the groove, so the upper edge support of the eaves gutter can rotate freely along the inner surface of the vertical piece or the inner surface of the vertical locking piece.

[0027] By providing an L-shaped locking portion on the upper edge locking piece of the eaves gutter, it is possible to provide an upper edge locking piece of the eaves gutter that can switch between a state in which the upper edge of the eaves gutter is locked by the locking portion through rotation of the upper edge locking piece of the eaves gutter, and a state in which interference with the eaves gutter can be avoided without the upper edge of the eaves gutter being supported by the locking portion.

[0028] 「9」 In this embodiment of the gutter support structure, the gutter is made of resin, and a configuration can be adopted in which multiple gutters are joined together via joints.

[0029] When joining multiple resin gutters, the ends of adjacent gutters are sometimes joined using a joint and adhesive applied to the joint. In this case, it is necessary to lift the end of one gutter and fit it into the other gutter, which is supported by a gutter support. In this process, by providing a rotatable upper gutter support piece on the gutter support, interference with the gutter end can be avoided, and a structure can be adopted that does not hinder the joining of gutter ends. [Effects of the Invention]

[0030] With the gutter support of the present invention, if the support body is attached to the tip of the eaves board of the roof and the gutter is supported on the inside of the gutter support, and a gutter upper edge locking piece is provided on the inside of the gutter support, the position of the gutter upper edge locking piece can be adjusted by rotating it to avoid interference with the gutter as much as possible. This allows for the smooth lifting of the gutter end inside the gutter support and the insertion of it into the end or joint of another adjacent gutter, in order to join the ends of adjacent gutters. Therefore, a gutter support can be provided that does not hinder the joining work of adjacent gutters. [Brief explanation of the drawing]

[0032] Hereinafter, an example of a gutter support and gutter support structure according to the first embodiment of the present invention will be described with reference to Figures 1 to 5. The gutter support according to this embodiment is used, for example, to support the gutter when attached to the tip of the eaves board of a corrugated metal roof. As shown in Figures 1 and 2, in the first embodiment, multiple gutter support members A are installed along the eaves of the corrugated metal roof B at predetermined intervals, and the gutter 40, which will be described later, is supported by multiple gutter support members A. The corrugated metal roof B shown in this embodiment consists of corrugated metal roofing material 4 with multiple peaks 2 and multiple valleys 3 alternating in a continuous pattern. In this embodiment, both the peaks 2 and valleys 3 are formed in a corrugated shape with an isosceles trapezoidal contour. Although there are various types of corrugated metal roofs B, such as seam-jointed, overlapping, and interlocking types, the gutter support members A in this embodiment can be applied to any type of corrugated metal roof.

[0033] As shown in Figures 1 and 2, the gutter support A is bolted to the tip 2A of the eaves board that forms the peak of the ridge 2 of the corrugated metal roof B. The gutter support A has a support body 10 which includes a lower piece 6 that forms a recess 5 into which the tip 2A of the eaves board can be inserted, an upright piece 7, and an upper piece 9. Below the support body 10, a vertical piece 16, a horizontal piece 17, a vertical locking piece 18, and a mounting piece 22, which will be described later, are arranged together with the support body 10 to form an overall rectangular shape.

[0034] In this example, a rising piece 7 is formed on a portion of the end piece 8, which is superimposed on one end of the lower piece 6 in the longitudinal direction, and rises from the lower piece 6 at an angle. An upper piece 9 is formed to extend this rising piece 7. The lower piece 6, rising piece 7, end piece 8, and upper piece 9 are all made of plate material of the same width. In this example, a groove is formed in the center of the upper surface in the width direction on the right end side of the lower piece 6, and flat plate portions 6B are formed on both sides of the groove, i.e., on both sides of the lower piece 6 in the width direction. A protruding wall 6D is also formed on the back side of the portion of the lower piece 6 where the groove is formed. A gap of a certain width is formed between the lower piece 6 and the upper piece 9, and the tip of the eaves board 2A of the corrugated metal roof B is inserted into this gap until its tip reaches the upright piece 7. In other words, the tip of the eaves board 2A is inserted into the recess 5.

[0035] In Figure 1, the gap between the lower piece 6 and the upper piece 9 has the rising piece 7 located at its left end as the far end, so the right end of the gap between the lower piece 6 and the upper piece 9 is referred to as the entrance side of the recess 5. On the right end side of the upper piece 9, an inclined piece 11 is formed in the portion located on the entrance side of the gap, sloping away from the lower piece 6. In the portion where this inclined piece 11 is formed, the gap between the lower piece 6 and the upper piece 9, that is, the opening on the entrance side of the recess 5, is widened, so when inserting the tip of the eaves board 2A of the corrugated metal roof B through this entrance side, the inclined piece 11 acts as a guide, making the insertion of the tip of the eaves board 2A easier.

[0036] In Figure 1, the upper vertical piece 12 extends downward from the right end of the lower piece 6 at an angle of approximately 90°. The upper vertical piece 12 has a groove 12A formed in its widthwise center, and flat plate portions 12B are formed on both sides of the groove 12A, i.e., on both sides of the upper vertical piece 12 in the widthwise direction. In addition, a protruding wall 12D is formed on the back side of the groove 12A of the upper vertical piece 12. The overall width, groove width, and flat plate portion width of the upper vertical piece 12 are formed to be the same width as the overall width, groove width, and flat plate portion width of the lower piece 6, respectively.

[0037] The lower vertical piece 13 is superimposed on the upper vertical piece 12, passing from the upper side through the central and lower sides, and further extending the upper vertical piece 12 downwards. A groove 13A is also formed in the lower vertical piece 13, and a flat plate portion 13B and a protruding wall 13D are formed therein. Since the lower vertical piece 13 has an overall width, groove width, and flat plate portion width that correspond to the overall width, groove width, and flat plate portion width of the upper vertical piece 12, the lower vertical piece 13 can be superimposed on the upper vertical piece 12. Furthermore, the upper vertical piece 12 and the lower vertical piece 13 are integrated by a bolt 14 that passes through the overlapping portion of the two pieces and a nut 15 screwed onto it, forming a vertical piece 16.

[0038] A horizontal piece 17 is formed at the lower end of the lower vertical piece 13, extending laterally at an angle slightly wider than 90° relative to the lower vertical piece 13. A groove 17A is also formed in the horizontal piece 17, and a flat plate portion 17B and a protruding wall 17D are formed therein. This horizontal piece 17 has an overall width, groove width, and flat plate portion width that are equivalent to the overall width, groove width, and flat plate portion width of the lower vertical piece 13. A short bent piece 17E is formed at the tip of the horizontal piece 17, with the horizontal piece 17 bent outward (downward) at approximately 90°. A vertical locking piece 18 is formed on the outside of this bent piece 17E so as to intersect the horizontal piece 17 at an obtuse angle of nearly 90°. This vertical locking piece 18 has a groove 18A, a flat plate portion 18B, and a protruding wall 18D formed along its entire length, similar to the horizontal piece 17. The length of the vertical locking piece 18 is slightly shorter than the length of the vertical piece 16. Therefore, the tip (upper end) of the vertical locking piece 18 extends to a position close to one end of the lower piece 6.

[0039] A bolt 20 and a nut 21 that screws onto it are provided so as to pass through the portion where the lower end of the vertical locking piece 18 overlaps with the bent piece 17E of the horizontal piece 17. This bolted structure allows the lower end of the vertical locking piece 18 to be rotatably and detachably connected to the bent piece 17E of the horizontal piece 17. The vertical locking piece 18 is rotatably connected to the tip of the horizontal piece 17 with the bolt 20 as the pivot axis. Since the bolt 20 is arranged parallel to the length of the horizontal piece 17, in other words, it can also be said that the vertical locking piece 18 is rotatably supported with the bolt 20, which is aligned with the length of the horizontal piece 17, as the pivot axis. Furthermore, the portion where the lower end of the vertical locking piece 18 overlaps the bent piece 17E of the horizontal piece 17 is not limited to a bolted structure using a bolt 20 and nut 21; for example, the bent piece 17E of the horizontal piece 17 and the lower end of the vertical locking piece 18 may be connected by a hinge. In this case as well, the vertical locking piece 18 is connected to the tip of the horizontal piece 17 so as to be rotatable with the hinge as the pivot axis.

[0040] An L-shaped mounting piece 22 is provided on the outer side of the upper end of the vertical locking piece 18, with its lower side aligned with the outer side of the upper end of the vertical locking piece 18 and its upper side aligned with the upper piece 9. The mounting piece 22 has a groove 22A in the center in its width direction, flat plate portions 22B on both sides of the groove 22A in the width direction, and a protruding wall 22D on the back side of the groove 22A. The lower side of the mounting piece 22 has a groove 22A, a flat plate portion 22B, and a protruding wall 22D, just like the vertical locking piece 18, and their overall width, groove width, and flat plate portion width are the same as the overall width, groove width, and flat plate portion of the vertical locking piece 18. For this reason, the lower side of the mounting piece 22 is superimposed and aligned with the outer side of the upper end of the vertical locking piece 18. A bolt 25 and a nut 26 that screws onto it are provided so as to pass through the portion where the lower side of the mounting piece 22 overlaps with the outer side of the upper end of the vertical locking piece 18.

[0041] The upper part of the mounting piece 22 is attached to the upper side of the upper piece 9 as an extension piece 22F. The upper tip portion of the mounting piece 22 is superimposed on the flat upper piece 9.

[0042] In the portion where the lower piece 6 and the upper piece 9 overlap with a gap in between, through-holes are formed so as to penetrate the lower piece 6 and the upper piece 9, and a first mounting bolt 31 is attached as a fixing member so as to pass through these through-holes. A nut 33 is screwed onto the first mounting bolt 31. In addition, in the portion where the extension piece 22F overlaps the upper piece 9, through-holes are formed so as to penetrate the extension piece 22F, the upper piece 9, and the lower piece 6, and a second mounting bolt 32 is attached as a fixing member so as to pass through these through-holes. A nut 34 is screwed onto the second mounting bolt 32.

[0043] As shown in Figure 1, when the tip portion 2A of the eaves board is inserted into the recess 5, a through-hole is also formed in the tip portion 2A of the eaves board so as to align with the aforementioned through-hole. Therefore, the first mounting bolt 31 is provided so as to pass through the lower piece 6, the upper piece 9 and the tip portion 2A of the eaves board inserted between them, and the gutter support A is fixed to the tip portion 2A of the eaves board by tightening the nut 33 screwed onto the first mounting bolt 31. Furthermore, the second mounting bolt 32 is provided so as to pass through the extension piece 22F, the upper piece 9, the lower piece 6, and the tip portion 2A of the eaves board inserted between them, and the gutter support A is fixed to the tip portion 2A of the eaves board by tightening the nut 34 screwed onto the second mounting bolt 32.

[0044] Figure 1 shows the state in which the gutter support A is attached to the tip 2A of the eaves board of the corrugated metal roof B. The gutter 40 is supported inside a rectangular frame enclosed by the vertical piece 16, horizontal piece 17, and vertical locking piece 18 of the gutter support A. The gutter 40 consists of a bottom plate 40A, an inner plate 40B, and an outer plate 40C. Outward-facing ear portions 40E are formed at the upper ends of the inner plate 40B and the outer plate 40C, respectively. As shown in Figure 1, in this embodiment, the height of the outer plate 40C of the gutter 40 is formed to be slightly higher than the height of the inner plate 40B. The gutter 40 is, for example, a large gutter made of resin, such as a large gutter with a base plate 40A that is more than 200 mm wide. It is preferable to apply a gutter support A to support such a large gutter 40. In the gutter 40, if the width of the base plate 40A is increased by 1.6 times, the cross-sectional area of ​​the flow path of the gutter 40 becomes three times larger. Since such a large gutter 40 becomes considerably heavy when filled with rainwater, it is desirable to apply a gutter support A with a robust structure like that of this embodiment.

[0045] Furthermore, in the gutter support A, a gutter upper edge locking piece 42 is formed on the inside of the lower vertical piece 13 to secure the upper edge of the inner plate 40B, and a gutter upper edge locking piece 43 is formed on the inside of the vertical locking piece 18 to secure the upper edge of the outer plate 40C. The upper edge locking piece 43 of the eaves gutter consists of a base end 43A that contacts the inner surface of the vertical locking piece 18, an upright piece 43B extending from the end of the base end 43A at approximately a right angle to the base end 43A, and an extended piece 43C extending from the tip of the upright piece 43B at approximately a right angle to the upright piece 43B. The upright piece 43B and the extended piece 43C form an L-shaped locking portion 43D. The base end 43A is rotatably supported by a screw (shaft member) 44 that penetrates the central part of the base end 43A and the adjacent vertical locking piece 18 in the thickness direction of the two.

[0046] The base end portion 43A is made of a concave curved plate, with its central portion facing the groove 18A of the adjacent vertical locking piece 18, and the central portion of the base end portion 43A in contact with the bottom of the groove 18A. The width of the base end portion 43A is formed to be approximately the same as the width of the groove 18A in the vertical locking piece 18, and is sized so that the periphery of the base end portion 43A and the inner wall of the groove 18A do not interfere with each other when the base end portion 43A rotates. Therefore, as the base end portion 43A rotates around the screw, the upper edge locking piece 43 of the eaves gutter rotates along the inner surface of the vertical locking piece 18. In addition, the length of the upright piece 43B (the length in the direction perpendicular to the base end portion 43A when the base end portion 43A is considered as a flat plate) is formed to be slightly longer than the horizontal length of the ear portion 40E formed on the eaves gutter 40. Furthermore, a downward-facing protective piece 41 is formed slightly below the position where the upper edge locking piece 43 of the eaves gutter is provided. The protective piece 41 consists of a base end 41A, an upright piece 41B, and a locking piece 41C. The protective piece 41 is fixed to the vertical locking piece 18 with its base end 41A fixed to the inner surface of the vertical locking piece 18, and the locking piece 41C is fixed to the vertical locking piece 18 with its locking piece 41C facing downward. As shown in Figure 1, when the extended piece 43C of the upper edge locking piece 43 of the eaves gutter covers the upper surface of the ear portion 40E of the eaves gutter 40, the protective piece 41 is positioned inside the ear portion 40E and supports the ear portion 40E of the eaves gutter 40.

[0047] The upper edge locking piece 42 of the eaves gutter consists of a base end 42A that is in contact with the inner surface of the lower vertical piece 13, an upright piece 42B that extends from the end of the base end 42A at approximately a right angle to the base end 42A, and an extended piece 42C that extends from the tip of the upright piece 42B at approximately a right angle to the upright piece 42B. An L-shaped locking portion 42D is formed from an upright piece 42B and an extended piece 42C. The base end portion 42A is rotatably supported by a screw (shaft member) 45 that penetrates the central part of the base end portion 42A and the adjacent lower vertical piece 13 and upper vertical piece 12 in the thickness direction of those pieces. The base end portion 42A is formed in a roughly U-shape with low side wall portions 42b provided on both sides in the width direction of the flat plate portion 42a, inclined relative to the flat plate portion 42a. The upper edge locking piece 42 of the eaves gutter is roughly U-shaped, but since it is made of resin and the side wall portions 42b are low, the base end portion 42A can be rotated slightly so that the side wall portions 42b can pass over the edge of the protruding wall 12D. Alternatively, if the base end portion 42A of the upper edge locking piece 42 of the eaves gutter is made flat, or if the inner surface of the lower vertical piece 13 is made flat, the upper edge locking piece 42 of the eaves gutter can be supported so as to be rotatable.

[0048] The following describes the work process for attaching the gutter support A to the corrugated metal roof B, which has the configuration shown in Figure 2, and for supporting the gutter 40 with the gutter support A. First, the tip 2A of the eaves plate of the corrugated metal roof B is inserted into the recess 5 of the gutter support A. With the eaves plate tip 2A aligned with the through holes formed in the lower piece 6 and the upper piece 9, the first mounting bolt 31 is inserted through these through holes, and the nut 33 is screwed onto the first mounting bolt 31 and tightened. Furthermore, the vertical locking piece 18 is rotated downwards around the bolt 20 so that the vertical locking piece 18 and the mounting piece 22 are facing downwards. In this initial state, the storage space partitioned by the horizontal piece 17 and the vertical piece 16 is not closed by the vertical locking piece 18 and the mounting piece 22, but is open.

[0049] The gutter support A can be attached to the tip 2A of the eaves board by fastening the first mounting bolt 31 and nut 33 together. In this state, the gutter 40 can be placed on the horizontal piece 17 of the gutter support A and temporarily supported. As shown in Figure 2, multiple gutter support brackets A are installed at the eaves. When installing gutters 40 on multiple installed gutter support brackets A, it is necessary to install one gutter 40 and then connect the other gutters 40 via joints (not shown). In this case, as explained earlier based on Figure 12, it is necessary to lift the end of the gutter 106 and fit the end of the gutter 106 into the joint 107 at the end of the already installed gutter 105.

[0050] In the case of the gutter 40 of this embodiment, as explained earlier based on Figure 12, it is necessary to install a joint (not shown) at the end of the already installed gutter 40, apply adhesive to the inner surface of this joint, and then lift and fit the adjacent gutter 40 into this joint. To achieve this, it is desirable to rotate the upper edge locking pieces 42 and 43 of the eaves gutter, as shown in Figure 1, upward so as not to interfere with the lifting and fitting of the eaves gutter 40, and to install them in a direction that avoids obstruction to the eaves gutter 40. After fitting the end of one gutter 40 into the joint of the already installed gutter 40 and joining them, the vertical locking piece 18 is rotated upward so that the vertical locking piece 18 and the mounting piece 22 are facing upward, and the extended piece 22F at the tip of the mounting piece 22 is placed on top of the upper piece 9.

[0051] If the upper edge locking piece 43 of the eaves gutter, which is currently facing upwards, is rotated downwards to the state shown in Figure 1 (downward), then the locking portion 43D of the upper edge locking piece 43 of the eaves gutter can be used to hold down the upper edge of the outer plate 40C, as shown in Figure 1. Also, if the locking portion 42D of the upper edge locking piece 42 of the eaves gutter was facing upwards, the upper edge locking piece 42 of the eaves gutter can be rotated so that the locking portion 42D faces downwards, as shown in Figure 1, to hold down the upper edge of the inner plate 40B.

[0052] When the extension piece 22F is placed on the upper piece 9, the through holes formed in the mounting piece 22, the upper piece 9, the tip of the eaves board 2A, and the lower piece 6 are aligned. The second mounting bolt 32 is then passed through these holes, and the nut 34 is screwed onto the second mounting bolt 32. After this, the upper edge locking piece 43 of the eaves gutter is rotated downwards to position the extension piece 43C inside the outer plate 40C, thereby enabling the eaves gutter 40 to be supported by the eaves gutter support A.

[0053] With the gutter support A configured as described above, the tip of the eaves board 2A can be inserted into the recess 5 of the support body 10, and the gutter support A can be temporarily fixed to the tip of the eaves board with the first mounting bolt 31 that passes through the upper piece 9 of the support body 10, the tip of the eaves board 2A, and the lower piece 6. If the vertical locking piece 18 is rotated downward in this state, the gutter 40 can be installed and temporarily supported along the horizontal piece 17 and the vertical piece 16. Furthermore, the process of inserting the tip portion 2A of the eaves board into the recess 5 of the support body 10 and tightening the first mounting bolt 31 can be performed safely and easily by a single worker.

[0054] With the gutter support A temporarily fastened by the first mounting bolt 31, the gutter support A is in a state where it can stably support even heavy objects. Therefore, even if a heavy gutter 40 is placed on the horizontal piece 17, the gutter 40 will not become unstable. For this reason, workers can perform the temporary support work on the gutter 40 safely and securely, even in places with poor working environments such as high places. Furthermore, when joining another gutter to a temporarily supported gutter 40 via a joint, it is necessary to lift and fit the end of the other gutter into the temporarily supported gutter 40, but the gutter upper edge locking piece 42 does not get in the way during this process.

[0055] Furthermore, after temporarily installing the gutter 40, the vertical locking piece 18 is rotated upward, allowing the extension piece 22F at the tip of the mounting piece 22 to be attached to the upper piece 9 of the support body 10. From this state, the gutter support can be completed by fastening the extension piece 22F, the upper piece 9, the tip of the eaves board 2A, and the lower piece 6 with the second mounting bolt 32 that passes through them and the nut 34 that is screwed onto it. In this case, to prevent the upper edge locking piece 43 of the eaves gutter from interfering with the upper edge of the outer plate 40C of the eaves gutter 40, rotate the tip of the upper edge locking piece 43 so that it is closer to the tip of the vertical locking piece 18. After attaching the extension piece 22F to the upper piece 9, rotate the upper edge locking piece 43 downward, and as shown in Figure 1, the locking portion 43D can be used to hold down the upper edge of the outer plate 40C. With the above configuration, the first mounting bolt 31 and the second mounting bolt 32 can stably support the gutter support A, allowing even heavy gutters 40 to be stably supported, and also enabling safe and easy installation.

[0056] If the gutter support A has the above configuration, then a portion of the lower piece 6, the upper vertical piece 12, the lower vertical piece 13, the horizontal piece 17, and the vertical locking piece 18 all have recessed grooves and protruding walls, so all of them have a structure that is resistant to twisting. Therefore, even if the gutter 40 is heavy and is subjected to shaking or twisting due to wind, earthquakes, etc., a robust gutter support A can be provided that can stably support the gutter 40. Furthermore, when supporting the gutter 40, if the gutter support A is fixed to the tip 2A of the eaves board using the first mounting bolt 31 and the second mounting bolt 32, torsional forces tend to concentrate on the upper side of the vertical piece 16 and the upper side of the vertical locking piece 18. In this regard, the upper side of the vertical piece 16 has a structure that is resistant to twisting because it is a two-layer structure consisting of an upper vertical piece 12 and a lower vertical piece 13 with a recessed groove and a protruding wall fitted together. Moreover, the upper side of the vertical locking piece 18 also has a structure that is resistant to twisting because it is a two-layer structure consisting of a vertical locking piece 18 and a mounting piece 22 with a recessed groove and a protruding wall fitted together. Therefore, the gutter support A is resistant to twisting and has a robust structure that can stably support the gutter 40.

[0057] Furthermore, the connection between the upper piece 9 and the mounting piece 22 is not limited to a bolted structure using the first mounting bolt 31 and nut 33; for example, the tip of the upper piece 9 and the tip of the mounting piece 22 may be connected by a hinge. In this case, the mounting piece 22 is connected to the tip of the upper piece 9 so as to be rotatable with the hinge as the pivot axis, and the mounting piece 22 is rotatably supported so as to rotate on the plane formed by the upper piece 9 and the mounting piece 22. Furthermore, the connection between the bent piece 17E of the horizontal piece 17 and the vertical locking piece 18 may also be made by hinge. In this case, the vertical locking piece 18 and the mounting piece 22 are rotatable by hinges, and the vertical locking piece 18 and the mounting piece 22 are connected by a bolt 25 that passes through the overlapping portion of the upper part of the vertical locking piece 18 and the lower part of the mounting piece 22, and a nut 26 that is screwed onto it.

[0058] In the gutter support A shown in Figures 1 to 4, the configuration of the part where the base end 43A of the upper edge locking piece 43 of the gutter is connected to the vertical locking piece 18 is as shown in Figure 5. When the vertical locking piece 18 is positioned with the groove 18A facing outward and the protruding wall 18D facing inward, it can be attached to the surface side of the protruding wall 18D (the inner surface side of the gutter support A). Conversely, as shown in Figure 6, when the vertical locking piece 18 is positioned with the groove 18A facing inward and the protruding wall 18D facing outward, it can be attached to the inner surface side of the groove 18A (the inner surface side of the gutter support A).

[0059] The cross-sectional shape of the vertical locking piece 18 can be of various shapes. For example, it may be flat, as shown in the vertical locking piece 46 in Figure 7, or it may be a vertical locking piece 47 with a cross-sectional shape having a flat central part 47A and outward-facing inclined pieces 47B on both ends, as shown in Figure 8. In the vertical locking piece 47 shown in Figure 8, a groove 47C is formed on the side sandwiched between the inclined pieces 47B, 47B. Furthermore, as shown in Figure 9, the vertical locking piece 48 may have a cross-sectional shape with a flat central portion 48A and side wall portions 48B formed perpendicular to both ends, or it may have a vertical locking piece 49 having an arc-shaped cross-section, as shown in Figure 10. In the vertical locking piece 48 shown in Figure 9, a groove 48C is formed on the side sandwiched between the side wall portions 48B. In the vertical locking piece 49 shown in Figure 10, a groove 49C is formed. Any of the cross-sectional shapes of the vertical locking pieces 46, 47, 48, and 49 shown in Figures 7 to 10 can be applied as the vertical locking pieces of the gutter support A in the previous embodiment. Furthermore, the vertical locking pieces 47, 48, and 49 can be applied without any problems whether the grooved side is facing inward towards the gutter support A or outward towards the gutter support A.
