Description

Technical Field

[0001] The present invention relates to an eaves gutter hanger that is fixedly attached to the eaves tip and suspends the eaves gutter.

Background Art

[0002] As an eaves gutter hanger of the type that suspends the eaves gutter from a folded plate roof using a suspension bolt, for example, Patent Document 1 discloses an eaves gutter hanger including a suspension bolt that is bolted through the folded plate roof, and a support main body portion that is attached to the lower end portion of the suspension bolt and on which the eaves portions of the eaves gutter are placed on both shelf portions. The suspension bolt passes through the suspension hole at the center of the support main body portion, and nuts are attached to both sides thereof. In this eaves gutter hanger, by moving the position of the nut up and down, the support main body portion can be attached at any position in the vertical direction of the suspension bolt. Therefore, there is an advantage that it is easy to adjust the height of the support main body portion to give a slight gradient to the eaves gutter. Further, as a method for adjusting the eaves gutter hanger in the front-rear direction, the support main body portion is provided with a suspension hole, and adjustment is performed by changing the position of the suspension bolt in the suspension hole.

[0003] Patent Document 2 discloses an eaves gutter hanger that suspends the support main body portion in the vertical direction at a position slightly behind the position of the suspension hole, although it is not a suspension bolt. On the other hand, in an eaves gutter hanger of the type that is attached not to the folded plate roof but to the eaves tip, there are those that support the support main body portion by a fixing portion that projects in the front-rear direction from the eaves tip, which are known from, for example, Patent Documents 3 and 4. In these support main body portions, since they are not of the type that suspends from a folded plate roof using a suspension bolt, it is relatively difficult to adjust the height position of the support main body portion.

Patent Document 1

Patent Document 2

Patent Document 3

[0005] The eaves gutter hanger shown in Patent Document 1 has the advantage of being easier to adjust the height of the eaves gutter compared to the eaves gutter hangers shown in other patent documents. On the other hand, the position where the suspension bolt can be attached in the front-rear direction of the support main body is 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 suspension hole is provided at the center in the front-rear direction of the eaves gutter hanger, and the suspension bolt vertically suspended from the folded plate roof supports it. In the general range of use, the limitation of the range of the suspension hole where the suspension bolt can be attached does not pose any problem. However, in actual construction, there may be cases where the suspension bolt cannot be used as it is due to special circumstances of the building.

[0006] Therefore, an object of the present invention is to provide an eaves gutter hanger that can be installed in response to special circumstances of a building while maintaining the advantages of the suspension bolt.

[0007] To achieve the above object, the present invention provides a support main body portion in which a strip-shaped metal plate is bent to form shelf portions on both ends of a central side portion for placing ear portions of an eaves gutter, and fixing holes are drilled in the central side portion. At least one of the shelf portions includes an inclined side portion extending obliquely from the central side portion, an upper side portion extending outward from the inclined side portion, a side side portion extending downward from the upper side portion, and a step portion extending the lower end of the side side portion toward the central side portion. A support main body portion, an elastic plate extending from the central side portion toward the step portion, a fixing portion attached to an end portion of a folded plate roof, a suspension bolt attached to the lower end of the fixing portion, An overlap surface portion that is in surface contact with the central side portion, and an overhang surface portion that protrudes in the left-right direction of the central side portion when the overlap surface portion is in surface contact with the central side portion, wherein the overlap surface portion is provided with a through hole that communicates with the fixing hole when overlapping the central side portion, and further, an offset fitting provided with a suspension hole in the overhang surface portion. The support body portion and the offset fitting are fixed with bolts and nuts through the communicated fixing hole and the through hole, and the suspension bolt penetrates through the suspension hole of the overhang surface portion and is fixed with nuts from above and below the overhang surface portion.

Effect of the Invention

[0008] According to the eaves gutter hanger of the present invention, by using an offset fitting, the suspension bolt is not bent, so that the advantage of easy height adjustment by the suspension bolt can be enjoyed as it is.

Mode for Carrying Out the Invention

[0010] [Example 1] An embodiment of the eaves gutter hanger of the present invention will be described. Fig. 1 shows a side cross-section in which an eaves gutter hanger 1 and an eaves gutter 3 are suspended by a suspension bolt on a folded plate roof 2. Fig. 1A shows the outer wall W1 of the building before renovation, and the broken line in Fig. 1A indicates the position of the outer wall W2 after renovation. When repairing the outer wall of the building to improve durability, earthquake resistance, and aesthetic appearance, the position of the outer wall often protrudes forward.

[0011] In Fig. 1A, the eaves gutter hanger 1 before the outer wall renovation attaches a fixing part 4 to the end of the folded plate roof 2, suspends a suspension bolt 7 joined by welding from the fixing part 4, and is attached through the support main body part 6 below the suspension bolt 7. After the outer wall renovation, the outer 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 since this cannot be moved, the support main body part 6 interferes with the outer wall W2.

[0012] Fig. 1B also shows the state after the outer wall renovation. An offset fitting 10 described later is applied to the eaves gutter hanger 1, and the position of the suspension bolt 7 has retreated to the outer wall W2 side compared to the case of Fig. 1A. Fig. 2 shows a perspective view of the eaves gutter hanger 1 (Fig. 2A) and the offset fitting 10 (Fig. 2B). Although the eaves gutter hanger 1 itself is a known one, 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.

[0013] In FIG. 2A, the eaves gutter hanger 1 includes a fixing portion 4, a suspension bolt 7, and a support main body portion 6. The suspension bolt 7 is inserted into the fixing hole 61 of the support main body portion 6 and is fixed so that its height can be adjusted by nuts up and down. The support main body portion 6 is formed by bending a strip-shaped metal plate, and a horizontal central side portion 64 is provided in the center. Both ends thereof are shelf portions 62 and 63 on which the ear portions 31 (see FIG. 1) of the eaves gutter having various shapes (for example, a parallel gutter, a front-high gutter, etc.) are placed. The fixing hole 61 is drilled longitudinally in the front-rear direction FB at the center of the central side portion 64. In the shelf portion 62 at at least one end (the rear side in the front-rear direction FB) of the illustrated central side portion 64, an inclined portion 65 extending obliquely from the central side portion 64, an upper side portion 66 extending outward in the horizontal direction from the inclined portion 65, a hanging side portion 67 extending downward from this upper side portion 66 and the inclined portion 65, and a stepped portion 68 extending the lower end of this hanging side portion 67 toward the central side portion 64 are provided. Further, it has a hanging side portion 69 extending downward the front end of the stepped portion 68. Further, an elastic plate 9 extending from the central side portion 64 side 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. The tip of this elastic plate 9 is further bent into a standing surface portion 9a, and at least a part of this standing surface portion 9a is located above the upper surface of the stepped portion 68. Although there are some elastic plates 9 whose roots are attached to the central side portion 64, the inclined portion 65, the upper side portion 66, etc., all extend from the central side portion 64 side toward the stepped portion 68 side. The ear portion 31 of the eaves gutter 3 is placed on the stepped portion 68 by pushing the elastic plate 9 from below, and the elastic plate 9 restored to its original position prevents the ear portion 31 from falling off. A similar configuration of the shelf portion 63 is also provided on the front side in the front-rear direction of the support main body portion 6, but the description thereof is omitted.

[0014] The suspension bolt 7 is erected vertically in the fixing hole 61 of the support main body portion 6. The fixing portion 4 is formed by bending a strip-shaped metal plate, and is attached by sandwiching the folded-plate roof 2 between two side portions overlapped with each other. The suspension bolt 7 is welded to the lower end of the fixing portion 4.

[0015] In FIG. 2B, the offset fitting 10 is formed by cutting out, punching, and bending a single metal plate, and includes an overlapping surface portion 10a that is in surface contact with the central side portion 64 of the support main body portion 6, and an overhanging surface portion 10b that protrudes in the left-right direction RL (front side in the figure) of the central side portion 64 when in surface contact with the central side portion 64. The overlapping surface portion 10a and the overhanging surface portion 10b are continuous surface portions. 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. Further, on the overlapping surface portion 10a, the other side (rear side in the figure) is bent upward to form a rib 10e that is long in the front-rear direction. The rib 10e is formed by bending perpendicularly from the overlapping surface portion 10a.

[0016] The overhanging surface portion 10b is provided with a suspension hole 10d in the front-rear direction FB. The position of the suspension 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 shown, it may be a long hole that is long in the front-rear direction FB in order to widen the adjustment range of the position. Further, on the front side of the overhanging surface portion 10b, a rib 10f that is long in the left-right direction RL is provided by bending perpendicularly from the overhanging surface portion 10b.

[0017] Figure 3 is a diagram for explaining the usage of the offset fitting 10. Figure 3A is an assembly diagram when applying the offset fitting 10 to the eaves gutter hanger 1, and Figure 3B is a diagram showing the state after assembly. The offset 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 and fixed with bolts 81 and nuts 82. The rib 10e contacts the side of the central side portion 64 (the back 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 front side in the figure) at its end. As a result, the offset fitting 10 and the eaves gutter hanger 1 can change their relative positions in the front-rear direction, but are mutually constrained in the left-right direction and the rotational direction. The suspension bolt 7 passes through the suspension hole 10d of the overhang surface portion 10b and is fixed with 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.

[0018] The overlapping surface portion 10a has a length such that the front side of the overlapping surface portion 10a reaches in front of the fixing hole 61 in a state where the fixing hole 61 and the through hole 10c communicate on the rear side. Also, in this state, the rear side of the overlapping surface portion 10a has a length that reaches below the elastic plate 9.

[0019] Returning to Figure 1B, by applying the offset fitting 10, the position of the suspension bolt has retreated to the outer wall side. Specifically, the offset fitting 10 is abutted from the lower side of the support main body portion 6, and the through hole 10c is 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 reaches forward beyond the position p on the left side that exceeds the fixing hole 61 (the fixing hole 61 does not appear in Figure 1 but ends on the right side of the position p. The same applies to the position P described later). Considering at the position p, the distance d between the support position q of the suspension bolt in Figure 1A and the position p is larger than the distance D between the support position Q of the suspension bolt 7 in Figure 1B and the position P on the left side that exceeds the fixing hole 61, and the moment applied to the position P is larger. However, the front side of the overlapping surface portion 10a can suppress the deformation of the support main body portion 6 by supporting up to the position P that reaches in front of the fixing hole 61.

[0020] Further, the overlapping surface portion 10a reaches below the elastic plate 9. Considering the elastic plate 9, in FIG. 1A, when the load on the eaves gutter 3 causes the ear portion 31 to be about to be pulled out from the shelf portion 62 downward, the elastic plate 9 may follow this and the ear portion 31 may be pulled out. On the other hand, in FIG. 1B, since the overlapping surface portion 10a reaches below the elastic plate 9, by preventing the deformation of the elastic plate 9 downward, it is possible to prevent the ear portion 31 from being pulled out.

[0021] And, the support position Q of the suspension bolt 7 is a position that interferes with the shelf portion 62 of the support main body portion 6, but by using the offset fitting 10, the shelf portion 62 can be avoided to either the left or the right. For this reason, there is an effect that the advantage of the ease of height adjustment by the suspension bolt 7 can be enjoyed as it is.

[0022] In the above embodiment, the ribs 10e and 10f of the offset fitting 10 are not essential although the performance deteriorates. Also, overhanging surface portions 10b may be provided on both sides of the overlapping surface portion 10a.

[0023] [Embodiment 2] In Embodiment 1, the eaves gutter hanger 1 for the relatively heavy eaves gutter 3 was shown, but in Embodiment 2, an eaves gutter hanger 100 for a lightweight gutter is shown. FIG. 4 shows perspective views of the eaves gutter hanger 100 (FIG. 4A) and the offset fitting 40 (FIG. 4B).

[0024] First, the eaves gutter hanger 100 will be described. The eaves gutter hanger 100 itself is a known one. The support main body portion 106 of the eaves gutter hanger 100 is formed of a strip-shaped metal plate thinner than the support main body portion 6 of Embodiment 1, and ribs 165 and 166 are provided on both sides to reinforce the strength. The elastic plate 109 extends from the central side portion 164 side toward the stepped portion. The front shelf portion 163 of the support main body portion 106 is adapted to fit into the hollow of the ear portion 31 of the eaves gutter 3. Other than these points, it is the same as the support main body portion 6 of Embodiment 1.

[0025] The offset fitting 40 is formed by cutting out, punching, and bending from a single metal plate, and includes an overlapping surface portion 40a that overlaps with the central side portion 164 of the support main body portion 106 in a plane, and an overhanging surface portion 40b that protrudes in the left - right direction from the central side portion 164 when overlapping with the central side portion 164. Between the overlapping surface portion 40a and the overhanging surface portion 40b, an intermediate surface portion 40e that rises by a height h and an intermediate surface portion 40f that overlaps with the shelf portion 162 are interposed. The height h is a height that exceeds the shelf portion 162 (including the ribs 165 and 166) on the rear side of the support main body portion 106. Further, on the overlapping surface portion 40a, a through - hole 40c that communicates with the fixing hole 161 is provided when overlapping with the central side portion 164. On the overhanging surface portion 40b, a suspension hole 40d is provided in the front - rear direction FB. The suspension hole 40d is also shown as a round hole similar to the suspension hole 10d, but it may be a long hole that is long in the front - rear direction FB in order to widen the adjustment range of the position.

[0026] With reference to FIG. 5, the usage of the offset fitting 40 will be described. In FIG. 5A, the offset fitting 40 is applied from above the central side portion 164 of the support main body portion 106, and the fixing hole 161 and the through - hole 40c are communicated and fixed with bolts 181 and nuts 182. In FIG. 5B, the ribs 165 and 166 of the support main body portion 106 contact the left and right ends of the overlapping surface portion 40a over the front - rear direction FB. As a result, the offset fitting 40 and the support main body portion 106 can change their relative positions in the front - rear direction FB, but are in a constrained state in the left - right direction and the rotational direction. A suspension bolt 7 is passed through the suspension hole 40d of the overhanging surface portion 40b, and the upper and lower parts are fixed with nuts 51 and 52. Therefore, the upper and lower positions can be adjusted by the nuts 51 and 52.

[0027] Also in this embodiment, although the position of the suspension bolt 7 interferes with the shelf portion 162 of the support main body portion 106 in the front - rear direction FB, by using the offset fitting 40, the shelf portion 162 can be avoided as shown by the arrow T in the left - right direction RL. For this reason, there is an effect that the advantage of the ease of height adjustment by the suspension bolt 7 can be enjoyed as it is.

[0028] [Example 3] FIG. 6 shows a eaves gutter hanger 300 that can be adapted to a folded plate roof 21 having an irregular shape. FIG. 6E shows a perspective view of the eaves gutter hanger 300. FIG. 6A shows a case where the application of the eaves gutter hanger 300 is suitable. In the figure, due to the relationship of the site, etc., it shows the building appearance of a folded plate roof 21 having an irregular shape in which a part of the roof is cut obliquely at an angle θ. When an eaves gutter is installed at the position of the broken line in the range H shown in FIG. 6B, although it has a small gradient for water flow, it can be installed almost horizontally (the suspension bolt 7 and the eaves gutter intersect almost at a right angle). On the other hand, in the obliquely cut range S, the eaves gutter does not intersect the suspension bolt 7 at a right angle. In such a case, in a general eaves gutter hanger using a suspension bolt, at present, the suspension bolt 7 is vertically lowered from the folded plate roof 21 and bent halfway so that the suspension bolt 7 and the eaves gutter intersect almost at a right angle. However, this makes it difficult to adjust the height, which is an advantage of the suspension bolt 7. This is because the direction of height adjustment has an angular component like the direction r in the figure.

[0029] FIG. 6C shows the state when the eaves gutter hanger 300 is used. The suspension bolt 7 is in a vertical line shape, but the support body part is inclined according to the gradient of the gutter. For the eaves gutter hanger 300, the support body part 6, the suspension bolt 7, and the fixing part 4 use the same ones as in Example 1. This eaves gutter hanger 300 is applied with an offset fitting 50 shown in FIG. 6D. The offset fitting 50 is different in that the overlapping surface part 50a and the overhanging surface part 50b form a predetermined angle compared with the offset fitting 10 shown in Example 1. This angle corresponds to the gradient of the gutter in the range S. Those having the same configuration as in Example 1 are denoted by the same reference numerals as in Example 1 and the description is omitted.

[0030] According to this embodiment, by using the offset fitting 50, the suspension bolt 7 is not bent, so there is an effect that the advantage of easy height adjustment by the suspension bolt can be enjoyed as it is.

[0031] In the above embodiment, the offset brackets 10 and 40 show an example where the overhang surfaces 10b and 40b protrude only in one direction in the left - right direction when the overlap surfaces 10a and 40a overlap the central side portions 64 and 164. However, they may protrude on both sides in the left - right direction.
