Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an eaves gutter support metal fitting used for constructing eaves gutter.

[Conventional technology]

Conventionally, the eaves gutter was constructed in a hanging shape by hooking the front and rear ears of the eaves gutter to a pair of U-shaped engaging parts provided on the eaves gutter support fitting, and the above-mentioned engaging parts after construction In order to prevent the ears from falling off from the roof, a spring-like retaining piece that backs up the ears is attached to the eaves gutter support fitting. However, when constructing large eaves gutters, such as rain gutters with decorative panels, in response to the recent demand for luxury products, the weight of the eaves gutters becomes heavier than that of polyvinyl chloride eaves gutters, which have traditionally been widely used. Since it is heavy and susceptible to wind pressure, the above-mentioned presser piece has been unable to reliably prevent the ear from falling off.

Therefore, the applicant proposed eave gutter support fitting A shown in FIG. This eaves gutter support fitting A is for eaves gutter 10
A support metal body 1 that holds 0 in a suspended manner is fixed by welding or the like to a support rod 2 fixed to a rafter 200 of the eaves, etc., and is hooked to the upper end of the rising part of the support metal body 1. In order to prevent the ear part 110 of the eave gutter 100 from lifting up, the ear part 110 is pressed against the above-mentioned rising part with a presser metal fitting 120.

According to such eaves gutter support fitting A, eaves gutter 100
can be reliably supported at the eaves.

[Problem that the invention attempts to solve]

However, with the above eave gutter support fitting A, the eave gutter 100
If supported, thermal expansion and contraction of the eaves gutter 100 due to temperature differences such as changes in air temperature will not be tolerated by the tightening force of the holding fitting 120. Therefore, there was a fear that the eaves gutter 100 would be deformed into a meandering shape, or that excessive force would be applied to the eave gutter joint (not shown) due to the deformation, causing the connecting portion of the eaves gutter 100 to come off. In order to eliminate such concerns, leave the wing nut 121 of the presser fitting 120 loosely tightened, and leave the ear part 11 of the eaves gutter 100.
0 is the rising part of the support metal fitting body 1 and the holding metal fitting 1
It may be possible to allow the wing nut 121 to slide while being sandwiched between the wing nuts 121 and 20, but if this is done, the wing nut 121 may loosen due to various vibrations and may even fall off. is not realistic.

In the present invention, even if the rigidity of the eaves gutter 100 is increased in order to reliably support the eaves gutter 100,
It is an object of the present invention to provide an eaves gutter support fitting that can effectively absorb thermal expansion and contraction of 0.00.

[Means for solving problems]

Means for solving the above problems will be explained with reference to FIGS. 1 and 2, which correspond to embodiments.

That is, the eaves gutter support fitting A of the present invention is suitable for eaves gutter 100.
The support metal body 1 is provided with a support metal body 1 for holding the support metal body 1 in a hanging shape, and the support rod 2 for supporting the support metal body 1 on the eaves, and the support metal body 1 is connected to the support rod 2 by the eaves gutter 10.
It is characterized in that it is attached to the support rod 2 via a coupling mechanism 4 that allows sliding in the longitudinal direction.

[Effect]

According to the above means, the support fitting main body 1 is connected to the support rod 2.
The eaves gutter 1 is attached to the support rod 2 while being attached to the
00 in the longitudinal direction, and can absorb thermal expansion and contraction in the longitudinal direction of the eaves gutter 100 attached to the support rod 2.

〔Example〕

In the eaves gutter support fitting A illustrated in FIG.
00 ear part 110 is hooked, and a screw shaft 122 and a wing nut 121 are attached to the rising part.
A presser metal fitting 120 attached using a metal plate prevents the ear portion 110 from lifting and flapping. That is, the wing nut 121 is completely tightened, and the ear part 110 is sandwiched between the rising part of the support fitting main body 1 and the holding fitting 120 in such a manner that it cannot slide in the longitudinal direction of the eaves gutter. Further, the other ear portion 120 of the eaves gutter 100 is held by a U-shaped engagement portion 11 formed on the support body 1, and is held by a spring-like presser piece 5 fixed to the support body 1. Prevents it from falling off. Next, the base end 21 of the support rod 2 is fixed to a rafter 200 at the eaves. The support rod 2 in the illustrated example is a so-called front-cast type, but this point does not apply whether it is a type fixed to the side of the rafter 200 or a type suspended from a folded roof. , it may be something else. The support body 1 is attached to such a support rod 2 via a coupling mechanism 4 consisting of a pair of pins 41 and 42 and a long hole 43 formed in the support body 1. The pin 42 has flanges 421 and 422 at its upper and lower ends, and these flanges 421 and 422 sandwich the support fitting body 1 and the support rod 2.

As is clear from FIG. 2, of the pair of pins 41 and 42 constituting the coupling mechanism 4, the inner pin 41 rotatably couples the support fitting body 1 and the support rod 2. In addition, the outer pin 42 is connected to the support rod 2.
and is inserted into the elongated hole 43. Further, the elongated hole 43 is formed in a small arc shape centered on the center of rotation of the support fitting main body 1 and the support rod 2, that is, the inner pin 41. Therefore, when the eaves gutter 100 held in a hanging manner by the support body 1 is thermally expanded and contracted in the longitudinal direction, the support body 1 is
Along with the eaves gutter 100, the elongated hole 43 is connected to the pin 42 on the outside.
It slides around the inner pin 41 within a range that can be displaced relative to the inner pin 41. Thereby, thermal expansion and contraction in the longitudinal direction of the eaves gutter 100 is effectively absorbed.

According to this embodiment, the inner pin 41 rotatably connects both the support metal body 1 and the support rod 2 without play, so that the connection state between the support metal body 1 and the support rod 2 is strong. There are some advantages. Note that by making the hole width of the long hole 43 sufficiently larger than the outer diameter of the outer pin 42, the long hole 43
It is no longer necessary to form it into a small arc shape as shown in FIG.

FIG. 3 shows a modification of the coupling mechanism 4. In the coupling mechanism 4 shown in the figure, a pair of pins 44 and 45 held by the support rod 2 are inserted into elongated holes 46 and 47 formed at two locations in the support body 1, respectively.
In this case, the elongated holes 46 and 47 are formed long in the longitudinal direction of the eaves gutter (not shown) held by the support metal body 1. According to such a coupling mechanism 4, the support fitting main body 1 relative to the support rod 2 can be moved within a range in which the elongated holes 46 and 47 can be displaced relative to the corresponding pins 44 and 45.
The eave gutter can be slid in the longitudinal direction. Since the sliding direction matches the direction of thermal expansion and contraction of the eaves gutter, there is an advantage that thermal expansion and contraction in the longitudinal direction of the eaves gutter can be easily absorbed.

In the eave gutter support fitting A described in FIGS. 1 to 3, the coupling mechanism 4 includes pins 42, 44, and 45 provided on the support fitting main body 1 side, and elongated holes 43, 46, and 47 provided on the support rod 2 side. Of course, it may also be configured by

FIG. 4 shows another modification of the coupling mechanism 4. The coupling mechanism 4 shown in the figure has a pair of U-shaped holding portions 22, 22 formed at both ends of the support rod 2 in the width direction at a predetermined location of the support rod 2.
The support metal body 1 is held between the metal parts 2 and 22 so as to be slidable in the longitudinal direction of the eaves gutter. This also provides the same effect of absorbing thermal expansion and contraction in the longitudinal direction of the eaves gutter as in the case of the other coupling mechanisms 4 described above. Further, the coupling mechanism 4 shown in the figure has the advantage that extra parts such as pins are unnecessary.

[Effect of idea]

As is clear from the above, according to the eaves gutter support metal fitting of the present invention, the support metal body can slide in the longitudinal direction of the eaves gutter with respect to the support rod, so that the eaves gutter is not lifted up or fluttering on the support metal body. Even if the eaves gutter is firmly fixed, thermal expansion and contraction in the longitudinal direction occurring in the eaves gutter is reliably absorbed by the sliding of the supporting metal body. Therefore, even if the eaves gutter with a large weight is firmly constructed using a highly rigid eave gutter support metal fitting, there is no need to worry about deformation of the eaves gutter or separation from the eaves gutter joint.
