Description

The present invention relates to an eaves gutter hanger that includes a round-rod-shaped hanging bolt whose upper part is attached to a roof panel, and a gutter support body that is fixed to the hanging bolt through a hole and supports the eaves gutter by hanging it.

Conventionally, there has been known an eaves gutter hanger that suspends and supports an eaves gutter using a gutter support body fixed to a hanging bolt (see, for example, Patent Document 1). Such an eaves gutter hanger is fixed to the roof panel by two sets of nuts inserted into the hanging bolt.

Specifically, the hanging bolt is fixed to the roof panel by clamping the top and bottom surfaces of the roof panel with two nuts inserted into the upper part of the hanging bolt, and the gutter support body is fixed to the hanging bolt by being sandwiched between the nuts inserted into the lower part of the hanging bolt.

However, as mentioned above, installing one eaves gutter hanger requires fastening nuts at two locations, one above and one below, and this work is also done at a high altitude, so it takes time and effort. Moreover, because the eaves gutter hangers are installed in multiple locations, adjusting the height of multiple eaves gutter hangers to create a water gradient in the eaves gutter takes a lot of time.

The present invention was made in consideration of the above circumstances, and its purpose is to provide an eaves gutter hanging device that can shorten the work time required for height adjustment.

In order to achieve the above object, the eaves gutter hanger of the present invention comprises a hanging bolt whose upper part is inserted into an opening in a roof panel and fixed by a pair of first nuts arranged vertically above the opening, and a gutter support body that supports the eaves gutter by hanging, and is fixed by a pair of second nuts arranged vertically above the hole to the hanging bolt inserted into the hole, the hanging bolt having a threaded portion formed separately at the top and bottom and a rotation operating portion located between the threaded portions, one of the threaded portions being a reverse thread, and at least one of the pair of second nuts being arranged in a rotation-prohibited state relative to the gutter support body.

The eaves gutter hanger of the present invention has the above-mentioned configuration, which can reduce the work time required to adjust the height of the eaves gutter hanger relative to the roof panel.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
The eaves gutter hanger 1 shown in Figures 1 to 6 includes a hanging bolt 2 whose upper portion is inserted into an opening 8a of a roof panel 8 and fixed by a pair of first nuts 5A, 5B arranged in the vertical direction of the opening 8a. The eaves gutter hanger 1 also includes a gutter support body 3 that is fixed to the hanging bolt 2 inserted into a hole 31 by a pair of second nuts 5C, 5D arranged in the vertical direction of the hole 31, and supports the eaves gutter 7 by suspending it. The hanging bolt 2 has threaded portions 21A, 21B formed separately at the top and bottom, and a rotation operation portion 23 located between the threaded portions 21A, 21B. One of the threaded portions 21A, 21B is a reverse thread, and at least one of the pair of second nuts 5C, 5D is arranged in a rotation-prohibited state with respect to the gutter support body 3.
This will be explained in detail below. The up and down directions are defined based on the state in which the eaves gutter hanger 1 is fixed to the roof panel 8. The first nuts 5A, 5B and the second nuts 5C, 5D in this embodiment are hexagonal nuts having a hexagonal outer circumferential surface in a plan view.

Figure 1 (a) is a schematic side view of the eaves gutter hanger 1 fixed to the roof shingle 8. The hanging bolt 2 shown in Figure 1 (a) is a generally round bar-shaped member extending in the vertical direction, made of a metal material such as stainless steel. The hanging bolt 2 has threaded portions 21A and 21B, which are male threads separated in the vertical direction. In this embodiment, the upper threaded portion 21A and the lower threaded portion 21B are male threads formed so that the thread pitch is the same. The upper threaded portion 21A provided at the upper end of the hanging bolt 2 is inserted into the opening 8a of the roof shingle 8, and the first nuts 5A and 5B are fastened so as to clamp the roof shingle 8. This fastening fixes the hanging bolt 2 to the roof shingle 8. The lower threaded portion 21B provided at the lower end of the hanging bolt 2 is inserted into the hole 31 of the gutter support body 3, and the second nuts 5C and 5D are fastened so as to clamp the body portion 30 in which the hole 31 of the gutter support body 3 is provided. This fastening fixes the gutter support body 3 to the hanging bolt 2.

Unlike the upper threaded portion 21A, the lower threaded portion 21B is configured as a reverse thread (left-handed thread). Unlike a normal screw like the upper threaded portion 21A, which advances (advances) when turned to the right (clockwise) and retracts (retreats) when turned to the left (counterclockwise) with respect to the direction of travel, the lower threaded portion 21B retracts when turned to the right and advances when turned to the left. Between the upper threaded portion 21A and the lower threaded portion 21B, a portion 22 where no male thread is formed is provided, and a rotation operation portion 23 is provided in this portion 22.

The hanging bolt 2 has a rotation operation part 23 provided by deforming the portion 22 between the threaded parts 21A and 21B. In this embodiment, the rotation operation part 23 is deformed into a flat shape so that the thickness of the approximate center part in the vertical direction of the hanging bolt 2 is smaller than that of the threaded parts 21A and 21B (see Fig. 1(a) and Fig. 1(b), which is a cross-sectional view taken along line A-A' in Fig. 1(a)). A through hole 23a is provided in the approximate center of this rotation operation part 23, penetrating it in the thickness direction. This through hole 23a is a square hole, through which the rotation operation rod 9, described later, is inserted.

The gutter support body 3, which is fixed to the lower threaded portion 21B of the hanging bolt 2, is a long member made of a metal material such as stainless steel, and has ear holders 32, 32 formed at both ends in the longitudinal direction (left-right direction on the paper surface of FIG. 1(a)) that hold the front ears 7a and rear ears 7b of the eaves gutter 7. In addition, the body portion 30 between the ear holders 32, 32 has an elongated hole portion 31 formed in it that extends along the longitudinal direction of the gutter support body 3.

The second nuts 5C and 5D have female thread grooves that can be screwed into the lower threaded portion 21B, which is a reverse thread. The second nuts 5C and 5D, which are arranged below the hole 31 (gutter support body 3), are arranged in a rotation-prohibited state relative to the gutter support body 3 by the rotation-prohibiting member 4. The rotation-prohibiting member 4 shown in FIG. 2(a) is made of a metal plate such as stainless steel, and has a rectangular base plate 40 with a through hole 41 through which the hanging bolt 2 is inserted. The base plate 40 has insertion portions 42, 42 that are inserted along the short side (width direction) of the hole 31 of the gutter support body 3 at approximately the center of both end faces in the short side direction. The insertion portion 42 is formed by bending it at a substantially right angle from the base portion 40, and the longitudinal dimension of the insertion portion 42 is substantially the same as the short dimension of the hole portion 31 of the gutter support body 3, and its vertical dimension is substantially the same as the vertical (thickness) dimension of the hole portion 31 of the gutter support body 3.

Nut holding portions 43, 43 that hold the lower second nut 5D are formed on both longitudinal ends 40a, 40a of the base plate portion 40 of the rotation prohibiting member 4. The nut holding portion 43 includes a side plate portion 43a that is bent at a substantially right angle from the longitudinal end portion 40a of the base plate portion 40 and abuts against the outer circumferential surface of the second nut 5D, and a lower plate portion 43b that is bent at a substantially right angle from the side plate portion 43a toward the through hole 41 and abuts against the lower surface of the second nut 5D. As shown in FIG. 2(b), the side plate portions 43a, 43a are spaced apart at a distance substantially equal to the diameter of the second nut 5D (between the opposing surfaces of the outer circumferential surface of the second nut 5D), and the base plate portion 40 and the lower plate portion 43b are spaced apart at a distance substantially equal to the height of the second nut 5D.

Next, an example of a method for fixing the eaves gutter hanger 1 configured as described above to the roof panel 8 will be described with reference to Figures 3 to 6. Note that the fixing method is not limited to the following procedure or method.
As shown in FIG. 3, the lower first nut 5B is fixed to the desired position of the upper threaded portion 21A of the hanging bolt 2. Then, the second nut 5C, the gutter support body 3, the rotation preventing member 4, and the second nut 5D are fixed to the lower threaded portion 21B, which is a reverse thread, in this order from the top. At this time, the insertion portion 42 of the rotation preventing member 4 is arranged along the short direction of the hole portion 31 of the gutter support body 3. Then, the upper threaded portion 21A of the hanging bolt 2, to which the gutter support body 3 is fixed to the threaded portion 21B, is inserted into the opening 8a of the roof panel 8. When the hanging bolt 2 reaches a predetermined position, the gasket 6B, the mountain washer 6A, and the first nut 5A are inserted from below into the part exposed above the opening 8a of the upper threaded portion 21A of the hanging bolt 2, in that order, to fix the hanging bolt 2 to the roof panel 8. The first nut 5A, the mountain washer 6A, and the gasket 6B may be integrally formed. In this case, the first nut 5A may be configured in a state in which it can rotate with respect to the washer 6A, or may be configured in a state in which it cannot rotate with respect to the washer 6A. In the manner described above, the eaves gutter hanger 1 including the hanging bolt 2 and the gutter support body 3 is fixed to the roof panel 8.

Next, an example of a method for adjusting the height of the eaves gutter hanger 1 after the eaves gutter hanger 1 is fixed to the roof panel 8 in order to adjust the water gradient of the eaves gutter 7 suspended and supported by the gutter support body 3 will be described. Below, a case in which the gutter support body 3 is moved upward will be described. First, the rotation of the upper first nut 5A is fixed by a tool such as a clamp (not shown) to prevent the first nut 5A on the upper side from rotating together with the hanging bolt 2 as it rotates. "Co-rotating" means that the nut rotates together with the bolt.

As shown in Figures 4(a) and (b), the rotation operating rod 9 inserted through the through hole 23a of the rotation operating part 23 is rotated in the direction of the two-dot chain arrow in Figure 4(c) along the axial direction of the hanging bolt 2. At this time, the hanging bolt 2 is rotated while holding the gutter support body 3 by hand so that it does not rotate with the rotation of the hanging bolt 2. The first nut 5A is prevented from rotating with the rotation of the hanging bolt 2 by a tool (not shown), and the second nut 5D is prevented from rotating with the rotation of the hanging bolt 2 by the rotation prohibition member 4, so that the hanging bolt 2 threads upward relative to the roof panel 8 and moves a distance a as shown in Figure 5.

The gutter support body 3, which is manually stopped from rotating, moves upward a distance a relative to the lower threaded portion 21B as the hanging bolt 2 rotates. Because the lower threaded portion 21B is configured as a reverse thread, when the upper threaded portion 21A screws forward and the hanging bolt 2 moves upward, the gutter support body 3 moves upward relative to the lower threaded portion 21B.

The upper threaded portion 21A and the lower threaded portion 21B have the same thread pitch, so when the hanging bolt 2 moves upward by a distance a relative to the roof panel 8 as described above, the gutter support body 3 also moves upward by a distance a relative to the lower threaded portion 21B. In other words, as shown in FIG. 6, the gutter support body 3 moves upward by a distance 2a, which is the sum of the distance a moved by the hanging bolt 2 and the distance a moved relative to the lower threaded portion 21B. Therefore, since the vertical movement of the gutter support body 3 is greater than the vertical movement of the hanging bolt 2, the distance between the roof panel 8 and the gutter support body 3 can be adjusted by a slight rotation of the hanging bolt 2, making it possible to shorten the work time.

In this embodiment, the hanging bolt 2 is rotated by inserting the rotating rod 9 through the through hole 23a of the rotating operation part 23, but the hanging bolt 2 may be rotated by grasping the rotating operation part 23 by hand without using the rotating rod 9. In addition, in this embodiment, the lower first nut 5B and the upper second nut 5C are not arranged in a rotation-prohibited state, so they rotate together with the hanging bolt 2 as it rotates. Therefore, as the hanging bolt 2 moves upward, the lower first nut 5B comes into contact with the roof panel 8. In addition, the hanging bolt 2 moving upward moves downward relative to the gutter support body 3 as the threaded portion 21B is screwed downward, so the upper second nut 5C comes into contact with the gutter support body 3. Then, due to the frictional force associated with this contact, the lower first nut 5B and the upper second nut 5C are fixed and the rotation together is suppressed, resulting in a rotation-prohibited state.

Note that, due to the nature of the materials, etc., there may be cases where the frictional force between the roof panel 8 and the gutter support body 3 is not sufficient to prevent the first nut 5B and the second nut 5C from rotating together, making it difficult to move the hanging bolt 2 upwards using the first nut 5B and the second nut 5C. In that case, the first nut 5B and the second nut 5C can be rotated once to loosen them, and then the hanging bolt 2 can be rotated again. In addition, a washer that increases the frictional force, or a metal fitting such as a leaf spring that applies a biasing force to press and stop the first nut 5B and the second nut 5C from rotating together may be interposed between the first nut 5B and the roof panel 8, and between the second nut 5C and the gutter support body 3.

Also, before adjusting the height, the lower first nut 5B and the upper second nut 5C may be set to a predetermined distance from the roof panel 8 and the gutter support body 3, respectively, before adjusting the height. Also, the lower first nut 5B and the upper second nut 5C may be arranged in a rotation-prohibited state using a tool (not shown) before adjusting the height, similar to the first nut 5A and the second nut 5D. In this way, the lower first nut 5B and the upper second nut 5C do not rotate together with the rotation of the hanging bolt 2, so the height adjustment of the gutter support body 3 can be performed smoothly.

In the above description, an example of height adjustment when the gutter support body 3 is moved upward is described, but the height adjustment may be performed by moving the gutter support body 3 downward. In that case, the hanging bolt 2 is rotated in the opposite direction to the direction in which it is moved upward, so that the hanging bolt 2 moves downward, and the gutter support body 3 moves downward relative to the lower screw portion 21B. In this embodiment, the lower first nut 5B and the upper second nut 5C are not arranged in a rotation-prohibited state, so that they rotate together with the hanging bolt 2 as it rotates, and are separated from the roof plate 8 and the gutter support body 3, respectively. In that case, after the height adjustment of the gutter support body 3 is performed, the lower first nut 5B and the upper second nut 5C are tightened again to fix the hanging bolt 2 to the roof plate 8 and the gutter support body 3 to the hanging bolt 2. Because the upper first nut 5A and the lower second nut 5D are fixed, there is no risk of them falling even if you let go of the hanging bolt 2 or the gutter support body 3. Therefore, after adjusting the height of the gutter support body 3, you can easily tighten the lower first nut 5B and the upper second nut 5C.

If the lower first nut 5B and the upper second nut 5C are arranged in a rotation-prohibited state before the height adjustment, they will not rotate together with the rotation of the hanging bolt 2, and will not separate from the roof panel 8 and the gutter support body 3. Therefore, if the lower first nut 5B and the upper second nut 5C are arranged in a rotation-prohibited state, there is no need to perform fastening work after the height adjustment, and the height adjustment of the gutter support body 3 can be performed smoothly. In other words, if the lower first nut 5B and the upper second nut 5C are arranged in a rotation-prohibited state, like the upper first nut 5A and the lower second nut 5D, the height adjustment of the gutter support body 3 in both the upward and downward directions can be performed smoothly.

In the height adjustment of the eaves gutter hanger 1 described above, the first nut 5A arranged above the opening 8a of the roof plate 8 is arranged in a rotation-prohibited state relative to the roof plate 8 by a co-rotation prevention tool (not shown), but this is not limited to this. For example, if the opening 8a of the roof plate 8 is formed as a square hole, as shown in Figures 7 (a) and (b), the mountain washer 6A may be configured as a rotation-prohibiting member having a plate-shaped insertion portion 6Aa that is inserted along the edge of the opening 8a. The mountain washer 6A is arranged so that the pair of insertion portions 6Aa, 6Aa face each other. The upper first nut 5A is configured integrally with the mountain washer 6A, which is a rotation-prohibiting member, in a state in which rotation is fixed. Therefore, the insertion portions 6Aa, 6Aa of the mountain washer 6A are inserted along the edge of the opening 8a, and the upper first nut 5A is arranged in a rotation-prohibited state relative to the roof plate 8.

Modifications of the mountain washer 6A that function as a rotation-preventing member include those shown in Figs. 7(c) and (d). In Figs. 7(c) and (d), the mountain washer 6A has, in addition to the insertion portion 6Aa of Figs. 7(a) and (b), a nut holding portion 6Ab that holds the upper first nut 5A by abutting at least a portion of the outer circumferential surface and the lower surface of the upper first nut 5A. Unlike Figs. 7(a) and (b), the upper first nut 5A is not integrally formed with the mountain washer 6A. The upper first nut 5A is held by the nut holding portion 6Ab of the mountain washer 6A, and the insertion portions 6Aa, 6Aa of the mountain washer 6A are inserted along the edge of the opening 8a of the roof panel 8, so that the upper first nut 5A is arranged in a rotation-preventing state relative to the roof panel 8.

In addition, when the roof plate 8 is a folded plate roof, the upper first nut 5A may be arranged in a rotation-prohibited state relative to the roof plate 8 using a cover member 80 as shown in FIG. 8(a). The cover member 80 is formed of a metal plate such as stainless steel bent along the shape of the roof plate 8 near the round hole-shaped opening 8a. The cover member 80 has an upper plate portion 81 and side plate portions 82, 82 provided at both ends of the upper plate portion 81 and sandwiching a part of the roof plate 8 from the width direction (the direction that coincides with the direction of appearance relative to the building, the left-right direction on the paper surface of FIG. 8(b)). The upper plate portion 81 is provided with a through hole 81a formed in a shape that follows the outer peripheral surface of the first nut 5A. As shown in FIG. 8(b), the cover member 80 is arranged so as to cover from above the roof plate 8 in a state in which the first nut 5A, the mountain washer 6A, and the packing 6B are arranged above. This causes the first nut 5A to fit into the through hole 81a of the cover member 80, and the upper first nut 5A is positioned in a non-rotatable state relative to the roof panel 8.

The configuration of the cover member 80 is not limited to that shown in the figure. For example, the through hole 81a may be formed in a round hole shape through which the hanging bolt 2 is inserted, and the upper first nut 5A may be fixed to the upper or lower side of this through hole 81a by welding or the like, so that the cover member 80 and the upper first nut 5A are integrally configured.

Next, modified examples of the rotation operation part 23 of the hanging bolt 2 will be described with reference to Figs. 9(a) to (f). Figs. 9(a), (c), and (e) are schematic side views of the hanging bolt according to the modified examples, Fig. 9(b) is an enlarged cross-sectional view taken along line D-D' in Fig. 9(a), Fig. 9(d) is an enlarged cross-sectional view taken along line E-E' in Fig. 9(c), and Fig. 9(f) is an enlarged cross-sectional view taken along line F-F' in Fig. 9(e).

The rotation operation part 23 shown in Figures 9(a) and (b) is provided by deforming a part of the area 22 between the threaded parts 21A and 21B, and its cross-sectional shape is formed into a substantially square rectangular shape that is smaller than the cross-sectional area of the threaded parts 21A and 21B. Because the cross-sectional shape of the rotation operation part 23 is formed into a rectangle, it is easy to grasp and turn the rotation operation part 23 by hand.

The rotation operation unit 23 shown in Figs. 9(c)(d) and 9(e)(f) is composed of a separate gripping member 24 fixed to the portion 22 between the screw portions 21A and 21B. In Figs. 9(c)(d), the center of the gripping member 24, which is a rectangular plate material, is deformed to fit the hanging bolt 2 and then fixed to the hanging bolt 2 by welding or the like, thereby forming the rotation operation unit 23.

In Figures 9(e) and (f), a gripping member 24, which is a hexagonal nut inserted up to the upper end of the lower threaded portion 21B of the hanging bolt 2, is fixed to the hanging bolt 2 by welding or the like, so that a rotation operation portion 23 is formed between the upper threaded portion 21A and the lower threaded portion 21B.

The configuration of the eaves gutter hanger 1 is not limited to that described above or shown in the figures. For example, the hanging bolt 2 may be configured with a reverse thread on the upper thread portion 21A instead of the lower thread portion 21B, and the upper thread portion 21A and the lower thread portion 21B may be configured with different lengths. In particular, if the lower thread portion 21B is configured to be longer than the upper thread portion 21A, the range of height adjustment of the gutter support body 3 can be increased. Furthermore, the upper thread portion 21A and the lower thread portion 21B may have different thread pitches.

For example, the through hole 23a may not be provided in the rotation operation part 23 shown in Figs. 1 to 6, and the rotation operation part 23 in Figs. 9(c) and (d) may be provided with a through hole for inserting the rotation operation rod 9. The configuration of other members may also be designed appropriately. The upper first nut 5A may be directly fixed to the roof plate 8 by welding or the like so as to communicate with the opening 8a, and may be arranged in a state where rotation is prohibited relative to the roof plate 8. The lower second nut 5D is not limited to using a rotation prohibiting member 4 in order to be arranged in a state where rotation is prohibited. The lower second nut 5D may be arranged in a state where rotation is prohibited using a tool or the like, similar to the upper first nut 5A, or may be arranged in a state where rotation is prohibited relative to the gutter support body 3 by being fixed by welding or the like to the lower surface of the gutter support body 3 so as to communicate with the hole 31. The lower first nut 5B and the upper second nut 5C may also be arranged in a state where rotation is prohibited by various methods. Furthermore, the configuration of the rotation prevention member 4 is not limited to that described above, and the material is not limited to metal but may be, for example, synthetic resin, etc.

In the above description, the first nut 5A on the upper side and the second nut 5D on the lower side are arranged in a rotation-prohibited state, or both the pair of first nuts 5A, 5B and the pair of second nuts 5C, 5D are arranged in a rotation-prohibited state, but the present invention is not limited to these. Instead, only the first nut 5B on the lower side and the second nut 5C on the upper side may be arranged in a rotation-prohibited state before the height adjustment is performed. If the first nut 5B on the lower side and the second nut 5C on the upper side are arranged in a rotation-prohibited state, it becomes easier to adjust the height of the hanging bolt 2 downward relative to the roof panel 8. In addition, when the first nut 5B on the lower side and the second nut 5C on the upper side are in a rotation-prohibited state, the distance between the second nuts 5C, 5D increases when the height adjustment is performed upward, and the distance between the first nuts 5A, 5B increases when the height adjustment is performed downward. Therefore, the first nut 5A on the upper side and the second nut 5D on the lower side are tightened again after the height adjustment. As a result, the first nuts 5A, 5B and the second nuts 5C, 5D clamp and fasten the roof panel 8 and the gutter support body 3.

The rotation operation of the rotation operation part 23 of the hanging bolt 2 may be performed not only when adjusting the height of the gutter support body 3, but also when attaching the hanging bolt 2 to the roof plate 8. In that case, before the installation work of the hanging bolt 2, the upper first nut 5A is communicated with the opening 8a and then placed in a rotation-prohibited state relative to the roof plate 8. Then, the lower first nut 5B is screwed into the desired position of the upper threaded part 21A, and the upper end of the hanging bolt 2 is passed through the opening 8a and brought into contact with the end of the female threaded hole of the first nut 5A. In this state, by rotating the hanging bolt 2 by the rotation operation part 23, the upper threaded part 21A is screwed into the first nut 5A, and the hanging bolt 2 is screwed and moved upward. At this time, it is preferable that the rotation of the gutter support body 3 is stopped by hand. Then, if the lower first nut 5B is not in contact with the roof plate 8 when the hanging bolt 2 reaches the desired position, the first nut 5B is tightened. By doing as described above, the first nuts 5A and 5B are tightened to clamp the roof panel 8, and the hanging bolt 2 is fixed to the roof panel 8.

Before the installation of the hanging bolt 2, it is not the upper first nut 5A but the lower first nut 5B that is connected to the opening 8a and then placed in a rotation-prohibited state on the roof panel 8. In that case, after the hanging bolt 2 screwed into the lower first nut 5B reaches the desired position, the upper first nut 5A is screwed into the upper threaded portion 21A, so that the first nuts 5A and 5B are fastened to clamp the roof panel 8, and the hanging bolt 2 is fixed to the roof panel 8. In addition, it is preferable that the lower first nut 5B is firmly fixed to the roof panel 8 so that the weight of the eaves gutter hanger 1 does not cause the lower first nut 5B to fall off the roof panel 8 when the hand is released from the eaves gutter hanger 1 before the upper first nut 5A is fastened. Also, both of the first nuts 5A and 5B may be connected to the opening 8a and placed on the roof panel 8 in a rotation-prohibited state before the work of attaching the hanging bolt 2 to the roof panel 8.

In addition, in the eaves gutter hanger 1 of this embodiment, even if the first nuts 5A, 5B and the second nuts 5C, 5D are spaced apart, the hanging bolt 2 can be rotated to adjust the distance between them. If the first nuts 5A, 5B and the second nuts 5C, 5D screwed onto the hanging bolt 2 are spaced apart, and the first nuts 5A and the second nuts 5D are arranged in a state where they cannot rotate relative to the roof plate 8 and the gutter support body 3, respectively, the hanging bolt 2 can be moved upward by rotating it. By simply rotating the hanging bolt 2, the distance between the first nuts 5A, 5B and the second nuts 5C, 5D is reduced, and the roof plate 8 and the gutter support body 3 are sandwiched between the first nuts 5A, 5B and the second nuts 5C, 5D, so that the construction work can be carried out efficiently.

The eaves gutter 7 is suspended and supported by multiple eaves gutter hangers 1. When the eaves gutter 7 is suspended and supported by multiple eaves gutter hangers 1, the height of the gutter support body 3, i.e., the height of the eaves gutter 7, may be adjusted to adjust the water gradient and height position of the eaves gutter 7. To adjust the height of the eaves gutter 7, multiple hanging bolts 2 may be rotated simultaneously, and to adjust the water gradient of the eaves gutter 7, the hanging bolt 2 to which the corresponding gutter support body 3 is fixed may be rotated. The eaves gutter hanger 1 of this embodiment can adjust the height of the gutter support body 3 by rotating the hanging bolt 2, so that the height can be adjusted even when the eaves gutter 7 is suspended and supported.
