Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an eaves gutter hanger that is attached and fixed to the edge of an eave to hang an eaves gutter.

As an eaves gutter hanger of the type that hangs the eaves gutter from the folded plate roof using a hanging bolt, for example, Patent Document 1 discloses a hanging bolt that penetrates the folded plate roof and is bolted, and a lower end of the hanging bolt. A gutter hanger is shown with a support body attached to the ledge and on which the eaves of the eaves gutter rest on both ledges. The suspension bolt passes through a suspension hole in the center of the support body, and is fitted with nuts on both sides thereof. With this eaves gutter hanger, the support body can be attached at any position in the vertical direction of the hanging bolt by moving the nut up and down. It has the advantage of being easy to adjust. Further, as a method of adjusting the eaves gutter hanger in the front-rear direction, the support body is provided with a hanger hole, and the adjustment is made by changing the position of the hanger bolt in the hanger hole.

Patent Literature 2 discloses an eaves gutter hanger, which is not a hanger bolt, but vertically hangs a support main body at a position slightly backward from the position of the hanger hole. On the other hand, in eaves gutter hangers of the type attached to the edge of the eaves instead of attached to the folded plate roof, a support main body is supported by a fixing portion projecting in the front-rear direction from the edge of the eaves. known by 4. Since these support bodies are not of the type suspended from the folded-plate roof using suspension bolts, it is relatively difficult to adjust the height position of the support bodies.

The eaves gutter hanger as shown in Patent Document 1 has an advantage that the height of the eaves gutter can be easily adjusted as compared with the eaves gutter hangers shown in other patent documents. On the other hand, the positions in the front-rear direction of the support main body where the suspension bolts are attached are limited to the range of the suspension holes provided in the support main body. In order to prevent deformation of the eaves gutter hanger due to a large load on the eaves gutter, the position of the hanging hole is provided in the center of the eaves gutter hanger in the front-rear direction, and it is hung vertically from the folded plate roof. It is supported by the suspension bolts that are mounted on the suspension bolts, and in the range of general use, the limitation of the range of the suspension holes to which the suspension bolts are attached poses no problem. However, in actual construction, the hanging bolts may not be used as they are due to the special circumstances of the building.

[Example 1]
An embodiment of the eaves gutter hanger of the present invention will be described.
FIG. 1 shows a side cross section of the eaves gutter hanger 1 and eaves gutter 3 suspended from the folded plate roof 2 by hanging bolts. FIG. 1A shows the outer wall W1 of the building before renovation, and the dashed line in FIG. 1A indicates the position of the outer wall W2 after renovation. When the outer wall of a building is repaired in order to improve its durability, earthquake resistance, and aesthetic appearance, it often happens that the outer wall protrudes forward.

In FIG. 1A, the eaves gutter hanging fixture 1 before the exterior wall renovation has a fixed part 4 attached to the end of the folded plate roof 2, and a hanging bolt 7 joined by welding is hung from the fixed part 4, and the hanging bolt 7 is attached through the support body portion 6 on the lower side of the . After the exterior wall renovation, the exterior wall W2 protrudes forward. The position of the suspension bolt 7 in the front-rear direction FB is the end position of the folded plate roof 2 and cannot be moved, so the support body 6 interferes with the outer wall W2.

FIG. 1B also shows the state after the exterior wall renovation. An offset fitting 10, which will be described later, is applied to the eaves gutter hanger 1, and the position of the hanger bolt 7 is set back toward the outer wall W2 compared to the case shown in FIG. 1A. FIG. 2 shows a perspective view of the eaves gutter hanger 1 (FIG. 2A) and the offset fitting 10 (FIG. 2B). The eaves gutter hanger 1 itself is known, but by applying the offset fitting 10 to the eaves gutter hanger 1, the eaves gutter hanger of the embodiment is formed. First, the eaves gutter hanger 1 will be described.

In FIG. 2A , the eaves gutter hanger 1 comprises a fixing portion 4 , a hanging bolt 7 and a support body portion 6 . The suspension bolt 7 is inserted through the fixing hole 61 of the support main body 6, and is fixed by a nut so that the height can be adjusted. The support main body 6 is formed by bending a strip-shaped metal plate, and has a horizontal central side 64 in the center, and both ends thereof have various shapes (for example, parallel gutter, front high gutter, etc.). Shelves 62 and 63 are formed on which the eaves 31 (see FIG. 1) of the eaves gutter are placed. The fixing hole 61 is elongated in the front-rear direction FB at the center of the central side portion 64 . At least one end (rear side in the front-rear direction FB) of the central side portion 64 shown in the figure has an inclined portion 65 extending obliquely from the central side portion 64 and an inclined portion 65 extending horizontally outward from the inclined portion 65 . A protruded upper side portion 66, a slant portion 65 and a hanging side portion 67 extending downward from the upper side portion 66, and a stepped portion 68 extending from the lower end of the hanging side portion 67 toward the central side portion 64 side. and Further, it has a hanging side portion 69 extending downward from the front end of the stepped portion 68 . Further, an elastic plate 9 extending from the central side portion 64 is provided between the central side portion 64 and the stepped portion 68 , and a gap is formed between the tip of the elastic plate 9 and the stepped portion 68 . there is The tip of the elastic plate 9 is further bent to a standing surface portion 9a, and at least a portion of the standing surface portion 9a is located above the upper surface of the stepped portion 68. As shown in FIG. Some of the elastic plates 9 have roots attached to the central side 64, the inclined portion 65, the upper side 66, etc., but all of them extend from the central side 64 side toward the stepped portion 68 side. The ear part 31 of the eaves gutter 3 is placed on the stepped part 68 by pushing the elastic plate 9 from below, and the elastic plate 9 restored to its original position prevents the ear part 31 from coming off. A shelf portion 63 having a similar configuration is also provided on the front side of the support body portion 6 in the front-rear direction, but the description thereof will be omitted.

The hanging bolt 7 is erected vertically in a fixing hole 61 of the support body 6 . The fixed part 4 is formed by bending a strip-shaped metal plate, and is attached by sandwiching the folded plate roof 2 between two side parts that are folded on each other. A hanging bolt 7 is welded to the lower end of the fixing portion 4 .

In FIG. 2B, the offset metal fitting 10 is formed by cutting, punching, and bending a single metal plate. It has an overhang surface portion 10b that protrudes in the left-right direction RL (front side in the figure) of the central side portion 64 when it comes into surface contact with the portion 64 . The overlapping surface portion 10a and the overhang surface portion 10b form a continuous surface portion. The overlapping surface portion 10a is provided with a through hole 10c that communicates with the fixing hole 61 when overlapping the central side portion 64. As shown in FIG. Further, the other side (back side in the drawing) of the overlap surface portion 10a is bent upward to form a rib 10e elongated in the front-rear direction. The rib 10e is formed by vertically bending the overlapping surface portion 10a.

The overhang surface portion 10b is provided with a suspension hole 10d in the front-rear direction FB. The position of the hanging hole 10d in the front-rear direction FB is on the rear side with respect to the through hole 10c. Although the suspension hole 10d is illustrated, it may be an elongated hole elongated in the front-rear direction FB in order to widen the adjustment range of the position. Further, on the front side of the overhang surface portion 10b, a long rib 10f is provided in the left-right direction RL by vertically bending the overhang surface portion 10b.

3A and 3B are diagrams for explaining how to use the offset metal fitting 10, FIG. 3A is an assembly diagram when applying the offset metal fitting 10 to the eaves gutter hanging tool 1, and FIG. 3B is a diagram showing the state after assembly. . The offset metal fitting 10 is applied from the lower side of the central side portion 64, and the fixing hole 61 and the through hole 10c are communicated with each other and fixed with a bolt 81 and a nut 82. - 特許庁The rib 10e contacts the side of the central side portion 64 (the far side in the figure) in the front-rear direction FB, while the rib 10f contacts the other side of the central side portion 64 (the near side in the figure) at its end. . As a result, although the offset metal fitting 10 and the eaves gutter hanging tool 1 can change their relative positions in the front-rear direction, they are mutually restrained in the left-right direction and in the rotational direction. A suspension bolt 7 is passed through the suspension hole 10d of the overhang surface portion 10b, and is fixed by nuts 51 and 52 from above and below the overhang surface portion 10b. Therefore, the vertical position can be adjusted by the nuts 51 and 52 .

The overlap surface portion 10a has a length such that the front side of the overlap surface portion 10a reaches the front side of the fixing hole 61 when the fixing hole 61 communicates with the through hole 10c on the rear side. In this state, the rear side of the overlapping surface portion 10a has a length reaching the lower side of the elastic plate 9. As shown in FIG.

Returning to FIG. 1B, by applying the offset metal fitting 10, the position of the suspension bolt is retreated to the outer wall side. Specifically, the offset metal fitting 10 was brought into contact with the support body 6 from below, and the through hole 10c was aligned with the rear side of the fixing hole 61 and fixed with a nut. In this state, the front side of the overlapping surface portion 10a is located at a position p on the left beyond the fixing hole 61 (the fixing hole 61 does not appear in FIG. 1 but terminates at the right side of the position p. the same) and reaches forward. Considering the position p, the distance d between the support position q and the position p of the suspension bolt in FIG. is larger, and the moment applied to the position P is larger. However, the front side of the overlap surface portion 10a can suppress the deformation of the support body portion 6 by supporting up to the position P that reaches the front side of the fixing hole 61 .

Moreover, the overlapping surface portion 10 a reaches the lower side of the elastic plate 9 . Considering the elastic plate 9, in FIG. is likely to be pulled out. On the other hand, in FIG. 1B, since the overlapping surface portion 10a reaches the lower side of the elastic plate 9, the downward deformation of the elastic plate 9 is prevented, thereby preventing the ear portion 31 from being pulled out. be able to.

Although the support position Q of the hanging bolt 7 interferes with the shelf 62 of the support body 6, the shelf 62 can be avoided by using the offset metal fitting 10 to either the left or the right. Therefore, there is an effect that the advantage of easiness of height adjustment by the hanging bolt 7 can be enjoyed as it is.

In the above embodiment, the ribs 10e and 10f of the offset metal fitting 10 are not essential although the performance is lowered. Overhang surface portions 10b may be provided on both sides of the overlap surface portion 10a.

[Example 2]
In the first embodiment, the eaves gutter hanger 1 for the eaves gutter 3 which becomes relatively heavy is shown, but in the second embodiment, the eaves gutter hanger 100 for the light gutter is shown. FIG. 4 shows a perspective view of the eaves gutter hanger 100 (FIG. 4A) and the offset fitting 40 (FIG. 4B).

First, the eaves gutter hanger 100 will be described. The eaves gutter hanger 100 itself is known. The support body portion 106 of the eaves gutter hanger 100 is made of a strip-shaped metal plate thinner than the support body portion 6 of the first embodiment, and is provided with ribs 165 and 166 on both sides in order to reinforce the strength. there is The elastic plate 109 extends from the central side portion 164 side toward the step portion. The shelf portion 163 on the front side of the support body portion 106 is fitted in the hollow of the ear portion 31 of the eaves gutter 3 . Other than these points, it is the same as the support body portion 6 of the first embodiment.

The offset metal fitting 40 is formed by cutting, punching, and bending a single metal plate. It has an overhang surface portion 40b that protrudes in the left-right direction from the central side portion 164 when it is closed. Between the overlap surface portion 40a and the overhang surface portion 40b, an intermediate surface portion 40e rising by a height h and an intermediate surface portion 40f overlapping the shelf portion 162 are interposed. The height h is a height that exceeds the shelf 162 (including the ribs 165 and 166) on the rear side of the support body 106. As shown in FIG. Further, the overlapping surface portion 40a is provided with a through hole 40c that communicates with the fixing hole 161 when overlapping the central side portion 164. As shown in FIG. 40 d of suspension holes are provided in the overhang surface part 40b at the front-back direction FB. Although the suspension hole 40d is also illustrated as a round hole like the suspension hole 10d, it may be an elongated hole elongated in the front-rear direction FB in order to widen the adjustment range of the position.

How to use the offset fitting 40 will be described with reference to FIG. 5A, the offset metal fitting 40 is applied from the upper side of the central side portion 164 of the support body portion 106, and the fixing hole 161 and the through hole 40c are communicated and fixed with the bolt 181 and the nut 182. In FIG. In FIG. 5B, the ribs 165 and 166 of the support body 106 are in contact with the left and right ends of the overlap surface 40a over the front-rear direction FB. As a result, the offset metal fitting 40 and the support main body 106 can change their relative positions in the front-rear direction FB, but are constrained in the left-right direction and in the rotational direction. A suspension bolt 7 is passed through the suspension hole 40d of the overhang surface portion 40b, and the top and bottom of the suspension bolt 7 are fixed by nuts 51 and 52. As shown in FIG. Therefore, the vertical position can be adjusted by the nuts 51 and 52 .

In this embodiment as well, the suspension bolt 7 is positioned at a position where it interferes with the shelf 162 of the support body 106 in the front-rear direction FB. can be avoided as shown in Therefore, there is an effect that the advantage of easiness of height adjustment by the hanging bolt 7 can be enjoyed as it is.

[Example 3]
FIG. 6 shows an eaves gutter hanger 300 that can accommodate a folded-plate roof 21 having an irregular shape. FIG. 6E shows a perspective view of the eaves gutter hanger 300. As shown in FIG. FIG. 6A shows a case where the eaves gutter hanger 300 is suitable for application. This figure shows the appearance of a building with a folded-plate roof 21 having an irregular shape in which a part of the roof is obliquely cut at an angle θ due to the site. If the eaves gutter is installed in the position of the dashed line in the range H shown in FIG. 6B, it can be installed almost horizontally (the suspension bolt 7 and the eaves gutter intersect at almost right angles) although it has a small slope for water flow. On the other hand, in the obliquely cut range S, the eaves gutter does not intersect the hanging bolt 7 at right angles. In such a case, in a general eaves gutter hanger using a hanging bolt, the hanging bolt 7 is vertically lowered from the folded plate roof 21 and bent halfway so that the hanging bolt 7 and the eaves gutter intersect at a substantially right angle. Currently, it corresponds to However, this makes it difficult to adjust the height, which is an advantage of the hanger bolt 7 . This is because the direction of height adjustment has an angular component as shown in the direction r in the figure.

FIG. 6C shows a state in which the eaves gutter hanger 300 is used, and the hanging bolts 7 are in a vertical line shape, but the support body is inclined according to the slope of the gutter. The eaves gutter hanger 300 uses the same supporting body 6, hanging bolt 7, and fixing part 4 as in the first embodiment. The eaves gutter hanger 300 employs the offset fitting 50 shown in FIG. 6D. The offset metal fitting 50 differs from the offset metal fitting 10 shown in the first embodiment in that the overlap surface portion 50a and the overhang surface portion 50b form a predetermined angle. This angle corresponds to the slope of the trough in range S. The same components as those of the first embodiment are given the same reference numerals as those of the first embodiment, and the description thereof is omitted.

According to this embodiment, since the suspension bolt 7 is not bent by using the offset metal fitting 50, there is an effect that the advantage of easiness of height adjustment by the suspension bolt can be enjoyed as it is.

In the above embodiment, the offset metal fittings 10 and 40 have the overhang surface portions 10b and 40b extending from the central side portion 164 in one horizontal direction when the overlapping surface portions 10a and 40a overlap the central side portions 64 and 164. Although only the protruding example is shown, it may be protruded on both sides in the horizontal direction.
