Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an eaves gutter support fitting formed by combining a mounting fitting fixed to an eaves member on the side of a house and a support fitting body.

[Conventional technology]

The eave gutter support metal fittings shown in the exploded perspective view in Figure 7 are as follows:
A mounting bracket 1 comprising a cross-shaped mounting leg portion 11 and a protruding portion 12, and U-shaped engagement portions 21 and 22 at both ends.
The main body 2 includes a support metal body 2 and a spring plate 3. In such an eaves gutter support metal fitting, the protruding part 12 of the mounting metal fitting 1 and the central part 2 of the supporting metal fitting main body 2
3 and the center portion of the spring plate 3 are joined together in a superimposed state. When the eaves gutter is installed, the edge of the eaves gutter (not shown) is connected to the engaging portion 2.
1 and 22, and both ends of the spring plate 3 are exposed to the back of the rim to prevent the rim from falling off.

Conventionally, the protruding portion 12 of the mounting fitting 1 and the central portion 23 of the support fitting main body 2 have been connected at one point using a rivet or a bolt/nut. They were also joined by spot welding.

[Problem that the invention attempts to solve]

However, in the case where one point is connected with a rivet or bolt/nut as described above, when a lateral force is applied to the support body 2, the support body 2 shifts in position in the direction of rotation around the joint point. However, the support body 2 was sometimes twisted relative to the protrusion 12. When such a twist occurs,
In the past, the edge of the eaves gutter that was locked to the engaging part 21 was caught on the engaging part 21, resulting in poor workability during construction of the eaves gutter, and after construction, the eaves gutter expanded and contracted due to changes in temperature, etc. This was no longer acceptable, and there was a problem in that it caused wavy deformation of the eaves and gutters.

In addition, if the parts are joined by spot welding, there will be no problem with twisting of the support metal body 2, but if the mounting metal 1 or the support metal body 2 is made of stainless steel, the quality of the joint will change due to the welding heat and the strength will deteriorate. is locally lowered, and the mounting bracket 1 and the support bracket main body 2 are likely to bend at the joint location.
Therefore, there has been a problem in that spot welding cannot be used as a joining means for stainless steel eaves gutter support fittings.

The present invention solves the above problems by devising a way to engage the mounting bracket and the support bracket body at their overlapping parts, thereby connecting them with rivets, bolts, nuts, etc. To provide an eaves gutter support fitting that does not cause twisting of the support fitting body.

[Means for solving problems]

The measures taken to solve the above problems are as follows: The mounting bracket fixed to the eaves member on the house side and the support bracket main body, which has an engaging part that locks the edge of the eaves gutter, are overlapped. They are connected via a shaft member such as a rivet, and a protruding piece formed by cutting and raising the tip of the mounting fitting downward is fitted into a hole formed in the support fitting main body.

[Effect]

In the eave gutter support metal fitting configured in this way,
When a lateral force is applied to the support body and the support body tries to shift in the rotational direction around the joint by the shaft member, the protruding piece engages with the periphery of the hole and prevents the shift. be done.

〔Example〕

FIG. 1 is an exploded perspective view of an eave gutter support fitting according to an embodiment of the present invention. The mounting bracket 1 shown in the figure has a hanging part 13 formed by bending a narrow metal plate at right angles.
A cross-shaped mounting leg 11 is formed by fixing a strip-shaped metal piece 14 perpendicularly thereto,
In addition, two parts of the protruding part 12 protruding from the upper end of the hanging part 13 are bent to form the inclined part 15 and the horizontal parts 16 and 17 on both sides thereof, and the protruding end of the horizontal part 16 on the tip side is bent in the width direction. The central part is cut and raised downward to form the projecting piece 18, and the horizontal part 1
A through hole 19 is formed in the center of the hole 6. The support metal body 2 has engaging parts 21 and 22 formed by bending both ends of a narrow metal plate into opposing U-shapes, and has the protruding piece 18 in the central part 23 of the metal plate.
A hole 24 and a through hole 25 having an opening width equal to or slightly larger than the width of the hole 24 and a through hole 25 are formed, and shoulders 26 and 27 are formed on both sides of the central portion 23. The spring plate 3 is formed by bending a narrow spring plate near one end into a chevron shape, and forming a through hole 31 in the horizontal portion. It is preferable that the opening width of the hole 24 be set to about 1/3 or less of the width of the support metal body 2 in order to ensure the necessary strength at the location where the hole is formed.

The mounting fitting 1, the supporting fitting main body 2 and the spring plate 3 are assembled as shown in FIGS. 2-4. That is, the horizontal part 16 of the mounting bracket 1 and the central part 2 of the support bracket main body 2
3 and the horizontal portion of the spring plate 3 are overlapped, and by caulking the rivet 4, which is an example of a shaft member inserted into each of the through holes 19, 25, and 31, the three members are riveted together at the overlapping portion. Furthermore, the protruding piece 18 is fitted into the hole 24.

According to such an eaves gutter support metal fitting, as is clear from FIGS. 4 and 5, the projecting piece 18 is attached to the periphery 24a of the hole 24 in the rotational direction A of the support metal body 2 around the rivet connection point. Since they are opposed to or engaged with each other, even if the support body 2 tries to shift in the rotational direction A, the protrusion 18 and the hole 24
are engaged with the peripheral edge 24a to prevent the displacement thereof. Further, the mounting fitting 1, the supporting fitting main body 2, and the spring plate 3 are reliably connected by the rivets 4 without wobbling. Note that instead of the rivet 4 described above, the connection may be made using a shaft member such as a bolt or nut.

The mounting leg portion 11 of the eaves gutter support metal fitting is fixed to an eaves member of a house, for example, a fascia. and,
As shown by imaginary lines in FIG. 2, the ear edges 110 and 120 of the eave gutter 100 are respectively engaged with the engaging portions 21 and 22 at both ends of the support fitting main body 2. and,
When the ear edges 110, 120 are locked to the engaging parts 21, 22, both ends 32, 33 of the spring plate 3 face the backs of the ear edges 110, 120, and the ear edges 110,
120 is prevented from retreating inward and falling off from the engaging portions 21 and 22.

In this embodiment, the length of the protrusion 18 is set to a length not longer than the wall thickness of the central portion 23 of the support body 2, and the protrusion 18 is configured not to protrude to the back side of the central portion 23. In this respect, for example, as shown in FIG.
By opening the hole 34 at
It may be configured to fit into the. If you do this,
Not only the positional displacement of the support fitting body 2 but also the spring plate 3
This has the advantage that it can also prevent misalignment. However, since the spring plate 3 is usually thin, the hole 34
In some cases, the strength of the location where the hole 34 is formed may be extremely reduced.In order to avoid such an extreme reduction in strength, the protruding piece 18 should be attached to the central portion as shown in FIG. It is desirable to have a structure that does not protrude to the back side of 23.

Moreover, although the hole 24 shown in FIGS. 1 and 5 is square, the shape of the hole 24 may be circular or other shapes. As for the eaves gutter support metal fittings, not only the above-mentioned front-mounted type, but also conventionally known types such as the driven-in type and the side-by-side receiving type are adopted.

[Effect of idea]

As explained above, in the eaves gutter support metal fitting of the present invention, the mounting metal fitting and the support metal body are connected by a shaft member such as a rivet at the overlapping portion of the two, and a shaft member such as a rivet is formed at the tip of the mounting metal fitting at the overlapping portion. Since the protruding piece is fitted into the hole made in the support body, even if a lateral force is applied to the support body and the support body attempts to shift in the rotational direction around the connection point,
The projecting piece engages with the periphery of the hole to prevent its displacement, thereby preventing the support fitting body from twisting relative to the mounting fitting. Therefore, the edge of the eaves gutter that is locked in the engaging part will not get caught in the engaging part, improving work efficiency when constructing the eaves gutter, and also prevents the eaves gutter from getting caught due to changes in temperature, etc. Expansion and contraction are always allowed, and there is no need to worry about waving deformation of the eaves and gutters.

In addition, since the mounting bracket and the support bracket body are not connected by welding such as spot welding,
There is no room for deterioration of the joint location due to welding heat. Therefore, the present invention can be applied to eave gutter support fittings made of stainless steel in the same way as to eave gutter support fittings made of other types of metal, and has the advantage that the strength of the joint portion can be sufficiently increased.

Furthermore, the eaves gutter support metal fitting of the present invention has a simple structure added to the conventional eave gutter support metal fitting by simply cutting the tip of the mounting metal part downward to form a protruding piece and opening a hole in the support metal body. There is also the advantage that no extra members are required and the configuration is simple.

Furthermore, since the projecting piece is formed by cutting and raising the tip of the mounting bracket downward, there is no reduction in the strength of the mounting bracket, and there is an advantage that the hanging strength can be maintained for a long period of time.
